Review And Reflection Of China International Textile Machinery Exhibition And ITMA Asia Exhibition 2014

Although 2014 China International Spin The machinery exhibition and ITMA Asia exhibition have been successfully concluded in June 20th, but the attention and discussion about exhibition exhibits are just beginning. During the exhibition, the textile machinery enterprises not only fully displayed their products, but also fully communicated with the users and internationally famous manufacturers, and made clear their future research and development directions. The user enterprises were more inclined to understand the trend of technology development and find the best transformation plan for the technological transformation of their own enterprises. In order to more fully reflect the exhibition, we invited Miu Dingshu, senior engineer of Suzhou textile engineering society, to talk about the highlights of this exhibition and suggestions on the development of textile and textile machinery industry after the exhibition.

From the 2014 China International Textile Machinery Exhibition and ITMA Asia exhibition, we can see that both exhibitors and users are paying more attention to the economic practicality of products. The production enterprises begin to pay attention to the user's individual needs, and the user's demand for products tends to be rational.

The author understands that most textile enterprises are visiting the exhibition with problems. Some enterprises and even a full range of production lines have arrived at the exhibition site. For example, the Xinjiang Yida textile factory is composed of more than 10 visiting teams led by the factory director, and 5 of the 3542 textile factories. After visiting the exhibition, many textile enterprises representatives said that the gap between the technological progress of domestic equipment and imported equipment is gradually narrowing.

Obvious progress of domestic mainframe

Although most people think that the number of new products at this exhibition is not large, it does not mean that there is no bright spot in this exhibition.

I believe that the main highlight of this exhibition is that the trend of high speed, high yield and high efficiency of the main engine is more obvious. For example, the PFA1505 intelligent electric spindle spinning machine exhibited by Shanghai Pacific Electric and Mechanical Group Co., Ltd., spinning the J50 yarn in real time, reached a speed of 21000 revolutions / min. at such a high spindle speed, there was almost no breakage. This device has been able to achieve high speed, high yield and high efficiency.

At the exhibition, Shanghai two textile machinery company first exhibited 1800 spindles of super long EJM198JL spinning frames. The doffing time of the machine was only 2.5 minutes (currently 4 minutes or more), and it was a high-speed and efficient spinning equipment. The machine adopts all electronic drafting, forming electronic cam, lifting and changing the steel collar plate smoothly.

Shanxi Best company first exhibited the new BS562 compact spinning long car, and equipped with automatic tube machine with automatic tipping bucket, which further reduced the labor intensity of the workers and reduced the employment.

The blowing carding system developed by Jiangyin Bai Tian machinery manufacturing company is in line with the current flexible opening and reducing technological requirements for fiber damage. It uses the dust filter instead of the traditional cotton coagulating device, effectively eliminates the short pile and dust. The centrifugal cotton collector uses airflow to remove the dust in the cotton, which is conducive to better carding machine.

　 Equipment close to international quality

It can be seen from the exhibition that the quality of domestic equipment has improved significantly, and some products have even reached the international advanced level.

For example, a FHMHg (composite) high precision bearing collar made by Chongqing Golden Cat Corporation uses Cr15 bearing steel pipe material, and uses intelligent CNC machining center equipment to overcome the problems of quenching / tempering integration, heat treatment and other difficult problems.

Zhejiang Zhong Rui Polyurethane Technology Co., Ltd. developed a subversion of the traditional nitrile rubber cots to attract everyone's attention. The hardness of the cots can reach 55 degrees and has excellent elasticity (the elasticity value is about 3 times of tradition). At present, the cots can not only be used to spin compact spinning, siro spinning compact spinning (speed can reach 450 m / min), but also achieve mass promotion on vortex spinning. In the 4 days before the exhibition, nearly 60 foreign enterprises had a strong interest in this new polyurethane cots. Some of them have repeatedly proposed to be agents of this product.

Zhejiang Jinfeng Textile Machinery Co., Ltd. has introduced a new type of cylinder clothing arrangement. On the basis of the original 5 sets of Xilin saw tooth card clothing, the organization added two rows of pins for the front end of the cylinder, and at the same time, the fan angle reached 95 degrees, which increased the length of the carding arc, and solved the problem of increasing the short staple and reducing the efficiency directly.

European textile machinery efficient and practical

At this exhibition, the most important foreign equipment for the author is the TC-11 high yield and high performance carding machine. The machine has optimized design, for example, carding radian reaches 2.8 meters, width increases to 1.28 meters, the capacity is increased by 40% under the same area, and the T-Con spacing setting optimization system can reduce 20% yarn faults. The TC-FCT cover plate accurate detection device truly achieves the same process on the vehicle and the machine. TC-NCT online nep detection device can realize on-line monitoring of cotton net and ensure product quality for a long time. The TC-MT magnetic cover system not only saves labor greatly, but also maintains simple and practical maintenance. In addition, the machine has another bright spot, that is, the carding machine has also developed a WEBFEED device for artificial cotton, which is equipped with a large single thorn roll with a diameter of 50% and a special angle pin. It broke through the current production of artificial cotton in carding machine is not high, the current output can reach 160 kg / hour, production capacity has been greatly improved. One such device can replace 3 ordinary carding machines.

Another foreign equipment that makes the author heartbeat is a blessing AUTOCONER-X5 winding machine that integrates today's high technology. 該機(jī)具有五大特點(diǎn)：一是采用數(shù)字式紗線橫動(dòng)技術(shù)，只須在顯示屏快速更改圈數(shù)、交叉角等絡(luò)筒參數(shù)，就可以得到個(gè)性化設(shè)計(jì)的筒子密度、直徑、規(guī)格;二是采用獨(dú)一無二的捻接技術(shù)，多樣化的模塊化設(shè)計(jì)，將捻接塊、退捻管以及氣路分配器組合成“快速更換裝置”，只須簡單步驟加上少量元件，無須單獨(dú)調(diào)節(jié)，就可把標(biāo)準(zhǔn)捻接器改為緊密紡紗捻接器、彈力捻接器、熱捻接器或噴濕捻接器;三是可實(shí)現(xiàn)全自動(dòng)、快速換批，無須手動(dòng)生頭，機(jī)上管紗一旦到位，X-Change落紗裝置就立即把紗線卷繞到空管上，以最快速度返回到工作面上;四是使用Ecopack裝置，紗線精密長度可控制在1%以內(nèi)，明顯減少了下道工序的浪費(fèi);優(yōu)化了下紗抓取動(dòng)作，防脫圈裝置置于頂部，有效防止下紗被吸入小吸嘴;五是顯示屏能以清晰符號、圖文和代碼向維修人員告知出現(xiàn)故障的單錠，并快速排除故障 To improve overall production efficiency and output.

In addition, USTER CLASSIMAT 5 is the latest yarn defect detection analyzer. The biggest feature of this instrument is that it can help users to use instrument testing to solve the overall quality problem of cloth. It is difficult to detect the fine neps and the thick and thin sections that can be found in the cloth. The latest alien fiber sensors can locate and classify the polluted yarn by multiple light sources, which can distinguish the harmful defects and harmless defects in the yarn. For the first time, the detection and classification of the polypropylene fiber content can be distinguished; the size and range of the bubbles can be analyzed by special periodic defects, and the severity of the defects can be displayed to prevent the possible occurrence of cloud spots in the woven or knitted fabrics. Besides the traditional H value, Mao Yuyi has also increased the more intuitive 3 mm hairiness detection commonly used in China's textile enterprises. The number of roots from 1 mm to 7 mm is both real and cumulative, and is detected at 400 m / minute under high speed conditions, and the detection efficiency is improved significantly. Its main functions are: solving past instruments
