automation equipment can effectively reduce employment /p >
"P >" the traditional spinning equipment has the problems of high labor intensity and more unit employment. Although the wages of the employees of the spinning enterprises are increasing year by year, the difficulty of recruiting workers has been plagued by the "a href=" "http://www.91se91.com/news/index_c.asp" > spinning enterprise < /a >. In addition to the soaring cost of labor, the spinning enterprises with low profits are aware of the need to solve the problems of employment and recruitment through the breakthroughs of equipment technology. The sixteenth Shanghai international "a target=" "_blank" href= "http://www.91se91.com/" > textile < /a > Industrial Exhibition of spinning equipment, from the comb to the collaterals, all in reducing the use of many innovations. The use of automation, continuous and intelligent high speed and high efficiency < a href= "http://www.91se91.com/news/ > spinning equipment < /a > becomes the main way to reduce labor intensity and reduce spinning labor. 
 1 to increase unit production and reduce allocation, 
 the Swiss Lida C70 carding machine, the German Te Luth Le TC8 carding machine and the British Cross Lo's MK-7 carding machine on the exhibition are all high-speed and efficient carding machines. The output of the single machine reaches 100 kg / h and 80 kg / h respectively. In recent years, Qingdao Hongda Textile Machinery Co., Ltd., Sura (Jintan) Textile Machinery Co., Ltd. and Jiaonan Jingwei Textile machinery factory have also adopted new measures, such as widening machine width and enhancing carding, to increase the output of single card. 
 by using blowing carding technology, especially increasing the unit output of the matching carding machine, the matching platform can be reduced. At the same time, the employment of the carding process has been significantly reduced. A 50 thousand spinning enterprise needs only 2 sets of blowing carding equipment, which can meet the production of the rear road, with 3~4 workers per class. 
 Shaanxi Baocheng Aviation Precision Manufacturing Limited by Share Ltd also exhibited the latest development of the two high-speed < a href= "http://www.91se91.com" > drawing frame < /a >. The BHFA1322 double row self levelling device has the speed of 600 m / minute for the high-speed drawing frame. The speed of the BHFA1382 type single eye high-speed drawing frame is 800 m / min, 2~3 times the speed of the traditional drawing equipment, and 2 sets for the 10000 spindles. 
 2 pre spinning large coil reduction, employment less than /strong > /p >
 at present, both the carding machine and the head drawing frame exhibited by domestic and foreign textile machinery manufacturers use the 1 meter diameter barrel to increase the capacity of the cotton sliver. The roving machine generally adopts 152 * 406 mm large coil, mostly suspended spindle roving frame, which creates conditions for large coil assembly. The capacity of the pre spinning equipment has been increased more than twice, compared with the traditional combing and rough equipment. 
 in automation, the automatic drawing changing technology is widely used in the drawing frame exhibited at this exhibition. In the roving machine, the automatic spinning technology is adopted in the roving machine produced by Seth Universal Machinery (Qingdao) Co., Ltd. and Tianjin Hongda Textile Machinery Co., Ltd. The data show that the doffing time of the roving frames is about 2 minutes, which not only shortens the time of stopping the doffing, but also saves more than 50% of the roving doffing workers, and has been popularized in many spinning factories in China. 
 at the speed of improving and coarse equipment, the highest speed of the German Te Luth Le TD-8 high-speed drawing frame displayed at this exhibition is up to 1000 meters / minute. The Swiss Lida D22 drawing frame can produce 4~6 tons per day, and ten million spindles can only match 1~2 sets. 
Most of the roving frames exhibited at this exhibition are suspended in P, and drive spindles and flyers separately to create conditions for roving machines at high speed. The spindle speed of suspended spindle roving machine can reach 1000~1200 revolutions per minute, nearly double the original spindle type roving frame. The number of spindles has also been increased generally in roving frames. For example, Germany's Tsing Ze company has 668 roving frames, each with 192 spindles, 72 more than the traditional roving machine. In recent years, Tianjin Hongda, Seth universal, Shanghai two spinning machinery Limited by Share Ltd and Hebei Taihang textile machinery company's roving machine has increased the number of ingots from 120 to 156~160 ingots in recent years. As the number of spindles per roving frame has increased by more than 1/3, it has reduced the number of roving frame from 3~4 to 2, saving the floor area and reducing 1/3's stroller.

 3 comber achieves high speed and high quality .
 combing machine exhibited on this exhibition has the characteristics of high speed and high quality. Shanghai one spinning machinery Co., Ltd., Jiangsu Kai Gong machinery Limited by Share Ltd and Shaanxi Hengxin precision textile machinery Co., Ltd. all displayed the high-speed comber, demonstrating speed between 450~500 clamp times / points. The equipment is running normally at the scene, the vibration is small, and the cotton web has no edge breaking phenomenon. 
 in actual production operation, if the domestic efficient comber can run normally at 400 times per minute, the output per unit can reach 50~60 kg / hour, and each comber (6 sets) produces 7~8 tons of combed sliver, which can produce 18.5 to 14.8tex combed yarn from 15 thousand to 20 thousand spindles. In addition, the CJ68 type high efficiency comber displayed on a spinning machine in Shanghai also increased automatic devices such as automatic roll changing, automatic joint and automatic delivery of small rolls, which not only reduced the labor intensity of the truck, but also eliminated the unevenness of the coiling and increased the quality of the combed strip. 
 because due to the rapid progress of domestic comber technology in recent years, the technical gap between the current "a href=" http://www.91se91.com "comber" less than /a has been getting smaller and smaller, which can completely replace the import, changing the situation that the original high quality combed yarn depends on the imported comber, and the domestic high-performance comber has a good performance price ratio. 
 4 spinning machine reduces labor intensity 
 the use of thick and thin connection technology. The roving, which is dropped from roving frame, can be directly conveyed to the roving frame of the spinning frame by the coarse and fine connection system. The roving conveyer is cancelled, and the spinning frame can be roped directly on the spinning frame, and the empty roving tube can be returned to the roving process by the connecting system. 
 collective doffing < a href= "http://www.91se91.com" > spinning frame < /a > reduces the number of doffing doffing workers by 2/3, and the doffing group can be reduced from 6 to 2. If a spinning workshop of 50 thousand spindles needs 5 doffing groups, the number of doffing workers can be reduced from 30 to 10, and 60 doffing workers can be reduced in three classes. 
 as the collective doffing spinning machine is developing trend, at this exhibition, the two spinning machines of Lang Wei, Shanghai, the flying machine of East Flying mare, the 4806th factory of the Chinese people's Liberation Army, the Changzhou Tonghe Textile Machinery Manufacturing Co., Ltd. and so on, all have exhibited the long spinning cars with collective doffing, and each spindle number is over 1000. In order to adapt to the spanformation of old spinning machines in domestic spinning mills and the fact that the production enterprises have many varieties and frequent alterations, the Jingwei Textile Machinery Limited by Share Ltd Yuci branch and East Fei Ma Zuo Li also launched the short dash of the collective doffing spinning frame, with the number of spindles between 420~600, and the number of ingot can be selected by the user enterprise, 
At P exhibition, Tongling song Bao Machinery Co., Ltd. exhibited its own S9 intelligent doffer. The equipment can pull and insert 10 bobbins at one time, and the doffing time of a 420 spindle spinning machine is about 90 seconds. After the doffing, the head retention rate can reach more than 95%, and the time of doffing stopping and the broken ends of doffing are better than that of manual doffing. There are 2 sets of intelligent doffer, which can be used for 24~30 spinning frames, and the doffing crew of each doffing group is reduced from 6 to 2~3. According to introducing, at present, more than 100 cotton mills in China are using more than 400 S9 intelligent doffer, which have achieved over 50% of saving labour and reduced the time of doffing to stop the platform, and the retrofit cost is lower than that of the purchasing collective automatic doffing spinning frame.

 5 the new spinning technology reduces the spinning work /p >
 compared with ring spinning, the new a href= "http://www.91se91.com" > spinning technology < /a > has abolished two processes of roving and winding. At the same time, the yarn forming mechanism is different from ring spinning, and is not limited by the speed of steel collar and wire coil, so it has the characteristics of short spinning process, fast spinning speed and high automation. The new spinning technology can reduce more than 1/2 of the yarn per ton of yarn than the ring spinning. In particular, as one of the most mature new spinning technologies, rotor spinning has run about 3500000 in China. 
At the P exhibition, the German luck company and Swiss Lida Company did not exhibit the prototype. However, they introduced the A-8 and R60 models, the two most advanced automatic spinning machines in the world. 480 and 540 spindles were installed on the two devices respectively, and the maximum speed of the spinning cups could reach 150 thousand rpm. 
 Shanghai Chun Rui Machinery Technology Co., Ltd. has exhibited ET420 and ET480 two semi-automatic rotor spinning machines, and has carried out the actual demonstration operation. The ET480 rotor spinning machine is specially designed for spinning medium and fine count yarn. 420 spinning machines are installed on each unit, and many major improvements have been made to the spinner. When spinning the 14.8tex viscose yarn at the exhibition, the speed of the spinning cup reaches 120 thousand revolutions per minute, which is not inferior to that of the imported similar ones. It shows that the domestic rotor spinning technology (except automatic rotor spinning machine) has also made great progress in recent years, and the gap with foreign countries is shrinking. 
 6 three types of machines to solve winding work more than /strong > 
 because the automatic winding machine adopts the technology of automatic joint, fixed length winding, automatic conveying yarn and so on, it is used as the 1/3 of the common winder. At present, the automatic winding machine has gradually replaced the traditional A series of ordinary winding machines, becoming the key direction of equipment spanformation in spinning mills. At this exhibition, many enterprises have exhibited automatic winding machines. All kinds of automatic winder displayed in Qingdao Hongda, Shanghai two spinning machine, East flying horse, Jiangsu and so on. The running speed of all kinds of automatic winder reaches 1000~1500 meters / minute, nearly twice that of the ordinary winder, the efficiency of the equipment can reach 90%, and it is 20% higher than that of the ordinary winder. The operation efficiency and speed of the automatic winder are higher than that of the traditional common winder, which can reduce the allocation and save labor. 
 tray type automatic winding machine adopts intelligent operation of automatic yarn changing tube, automatic conveying of empty bobbins, automatic replenishment of bobbins, automatic dropping yarn and so on, and its technology has made remarkable progress than that of yarn library type automatic winder. Therefore, the pallet type automatic winding machine has begun to replace the yarn library automatic winding machine. The yarn winder type automatic winding machine can only see one per person, while the tray type can watch 3~4 units per person. The automatic winder, which is from Germany, Japan, Murata and Italy, has been put on the market and used by spinning enterprises in China. At this exhibition, Qingdao Hongda displayed the SMOR-M pallet type automatic winding machine, which indicates that the home-made pallet automatic winding machine will soon be put on the market. 
 < a href= "http://www.91se91.com >" thin link equipment < /a > has been popularized and applied abroad. At this exhibition, a POL winder displayed by Italy's bio show is an automatic winding machine specially designed for spinning connection. The machine can be connected to 2000 spindles at most. The popularization and application of the thin link couplet indicates that the winding process is developing towards automation, continuity and unmanned operation. The automatic winder has gone through three developing stages: yarn storehouse type, pallet type and fine thread connection, so that the winding process will become the least working procedure in spinning process, which is a major breakthrough in the progress of spinning technology.

 online testing to improve yarn quality 
 because at present, the supply of domestic spinning capacity exceeds demand, < a href= "http://www.91se91.com" > spinning enterprise < /a > medium and low grade yarn of conventional production needs not only the fierce competition of similar products, but also the risk of no profit or even loss. Therefore, more and more spinning enterprises realize that in addition to eliminating backward spinning equipment, automatic control and on-line testing technology must be adopted to improve yarn quality and grade and occupy the market. At the sixteenth Shanghai international textile industry exhibition, a number of new technologies such as automatic control and on-line detection were displayed around the upgrading of yarn quality and grade. 
 1 compact spinning and siro spinning combined 
"P > > a href=" http://www.91se91.com "> spinning machine enterprise < /a > shows many spinning machines that use compact spinning and siro spinning technology to improve yarn quality. 
 the effect of compact spinning technology on reducing yarn hairiness and improving yarn strength has been recognized by the people in the industry. At present, this technology is accelerating. According to relevant information, about 10000000 spinning frames in China have adopted compact spinning technology. 
 but the spinning frame on this exhibition will combine compact spinning with Siro spinning technology. It shows that the integration of the two technical advantages is more conducive to improving the yarn quality and grade of ring spinning, and is the inevitable choice for producing high quality yarn. 
 2 blowing carding unit uses self levelling .
 in the blowing carding process, especially the carding machine, the equipment exhibited on this exhibition has been widely used in self-adjusting leveling and frequency conversion control technology to control the weight difference of the output strip, and the carding area is enlarged by raising the cylinder and reducing the doffer position. 
 the British MK7C A high yield carding machine adopts unique A type rack. Its biggest advantage is that it brings greater carding area. The JWF1209 carding machine produced by Qingdao Hongda Textile Machinery Co., Ltd. also increased the length of the carding area to 2.76 meters, which increased the carding area by 74%. 
 in addition, the C70 carding machine of the Swiss Lida Company adopts an integrated automatic grinding system. The TC8 carding machine produced by Germany's TLC is equipped with T-CON carding machine spacing optimization setting tool and on-line NEP monitoring device. 
 the application of these new technologies enables the carding machine to keep at a high level at high speed and lay a solid foundation for improving yarn quality. 
 3 roving machine multi motor drive 
 the a href= "http://www.91se91.com" > the roving machine < /a > almost all adopts the automatic control technology of multi motor drive. 
 motors respectively drive rollers, spindles, spindles and dragons to improve the synchronicity of the components, and achieve constant tension spinning, so that the winding tension of the front and rear flyers and large, medium and small yarns of roving will be the same. 
 this has good effect on improving roving structure, improving evenness and reducing weight difference of roving, and using multi motor roving function to provide high quality roving for spinning process.

 4 winding electronic yarn cleaning 
 winding is a key process to control the quality of yarn. In addition to the continuous use of electronic yarn clearer produced by Uster or Luo Fei company for continuous monitoring of yarn and removal of defects and foreign objects on yarn, a new type of capacitive or photoelectric fiber sensor is installed at the core of the yarn clearer. Among them, different fiber sensors are equipped with a variety of light sources to detect various colored fibers, which can distinguish colored fibers from harmless plant fibers and play a role as scouts in improving the quality of the yarn. 
Besides, P also displays a new generation of CLASSIMAT-5 yarn fault grading instrument, which extends the yarn fault classification from the original 2~3 to the 4~5 level, so that smaller yarn faults can be detected and graded. It is combined with the Uster-Q3 type electronic clearer. It is more scientific to control and remove the yarn defects, making the yarn quality superior and praised by users. 
 5, the application of on-line monitoring 
 in addition to increasing the output speed, the online drawing and self leveling technology commonly used in the drawing frame of the "a href=" http://www.91se91.com "spinning machine enterprise < /a" at home and abroad can correct the weight difference of the output strip in time, so that the weight deviation of the strip can meet the set requirement and create favorable conditions for the control of the yarn weight irregularity. 
 show the spinning equipment analysis of various processes from the exhibition. Due to the technological progress of domestic textile machinery manufacturing industry in recent years, the gap between domestic equipment and foreign similar products is narrowing.
