Behind The Scenes Exploration Of Textile Machinery Products Upgrading

Though many

The managers of enterprises have been accustomed to the rhythm of the industry for several years and bad years, but they are somewhat lacking in confidence in this year's market.

In fact, as early as the advent of the world financial crisis in 2008, the plight of the whole industry has already begun to emerge. Only after the support of financial policy, the surge in industrial capacity has temporarily covered these problems.

In the second half of 2011, with the continuous downturn of the international market and the rapid growth of labor costs, the industrial predicament caused by overcapacity was once again highlighted.

The people even estimate that the whole industry will not be very good in the next 3~5 years, and the prelude to shuffle the industry has been opened.

New trend of environmental protection, energy saving and ecology

There are two ways to increase profits. One is to find ways to generate revenue and the other is to save as much as possible.

With the rapid growth of human capital and production cost, how to economize has become the focus and main outlet of many enterprises.

Against this background, eco environmental protection and energy saving products have become a bright spot and trend of spinning equipment.

At the China International Textile Machinery Exhibition and ITMA Asia Exhibition held this year, the eco self twisting spinning machine developed by the company has the advantages of saving power, reducing the amount of waste silk, reducing the floor area, and giving the operator a maximum of 22 stands.

It is understood that 110 ecological self twisting spinning machines can produce 300 kilograms of yarn per hour, which is equivalent to 6000 spindles of ring spinning, followed by winding of 120 spinning spindles and twisting of 1344 times twisting spindles after ring spinning.

Taking 300 kilograms of yarn per hour, for example, the output speed of the self twisting spinning machine is 230 meters per minute, and the power consumption per kilowatt hour is 1.7 kilowatts per hour. 110 units consume 187 kilowatts per hour, while the traditional ring spinning, winding, twisting and other equipment can consume nearly 450 kilowatts per hour.

The intelligent electrical spindle spinning machine exhibited by the Pacific Electric and mechanical group company has a roving broken end roving stop feeding device. The device is linked with the electric spindle to realize the roving stop feeding after the broken ends of the spinning frame, which effectively reduces the number of flowers returned and the reading table of the equipment, reduces the labor cost and reduces the production cost.

Through the digital control system of the whole machine, the machine can monitor the change of spinning tension, optimize the spinning tension curve, and increase the average production speed of one doffing, and the production efficiency of the whole machine can be increased by more than 10%.

The highest working speed of the HXFA299B comber developed by Shaanxi Hengxin precision textile machinery Co., Ltd. is 500 clamp times / min.

This machine has improved the drafting structure, reduced the parking rate and improved the overall productivity of the equipment. The machine has adjusted the eccentricity of the timing adjusting disc and the eccentric copper sleeve, and has effectively reduced the resistance of the equipment and reduced the power consumption by 8%.

High speed, stability, reliability, new development and new breakthrough

At present, the most obvious difference between the domestic spinning equipment and the foreign advanced equipment is still in the direction of stability and reliability, and this gap will be more obvious in high speed production.

With the continuous progress of weaving technology of domestic spinning machines, this gap has gradually narrowed. This is also a reason why more and more domestic users have gradually recognized the domestic spinning equipment.

This change is reflected in both the Qing, the combing equipment and the coarse and fine equipment.

For example, at the China International Textile Machinery Exhibition and ITMA Asia Exhibition held this year, the JWF1209 wide carding machine exhibited by Qingdao Hongda Textile Machinery Co., Ltd. widened its work width to 1.5 meters on the basis of the original equipment, adjusted the carding system, raised the cylinder and lowered doffer, which increased by 74% compared with the traditional carding machine.

The machine adopts a new feeding box and provides stable cotton, which effectively improves evenness and weight irregularity.

The TMFD81L drawing frame introduced by Tianmen textile machinery company is equipped with Ulster's UQA fragment self levelling system. It has the functions of on-line detection, quality monitoring, fault diagnosis and so on. The effect of leveling is remarkable and stable.

The SXF1589 type spinning frame of Shanxi Hongji Polytron Technologies Inc adopts synchronous draft and two-way pmission of vehicle tail. It not only ensures the synchronous pmission of the front middle rear roller, but also has stable and reliable draft.

The JSFA588 comber developed by Jiangsu Kai Gong machinery Limited by Share Ltd has the advantages of high speed, high yield, high efficiency, low energy consumption, low noise and low vibration.

The air turbine is optimized and analyzed to ensure that the cotton web is clear, without edge breaking, holes and cloud spots.

Modular automation, less labor and easy maintenance

The modular and automatic technological progress of spinning equipment has provided technical guarantee for textile enterprises to reduce labor consumption and reduce maintenance workload.

At the China International Textile Machinery Exhibition and ITMA Asia Exhibition held this year, the CMT1801 fully automatic doffing roving machine introduced by Seth Universal Machinery (Qingdao) Limited does not affect the normal operation of the spinning system when the doffing roving machine is being repaired. The success rate of doffing is high, and the 8 machine synchronous control is adopted to achieve the real man-machine conversation.

Hebei Taihang FA469 automatic doffer has the function of automatic collective doffing. On the basis of retaining the characteristics of FA467E, the machine adopts external independent collective doffing form and two degree of Freedom Dragon bar mechanism to simplify the doffing process and achieve truly unattended doffing.

The SMARO- two thin winding automatic winder developed by Qingdao Hongda Textile Machinery Co., Ltd. adopts intelligent single spindle, which realizes automatic restarting, automatic lifting and automatic yarn conveying. It saves manpower and realizes direct and automatic connection and continuous production.

The TH498 intelligent high speed collective doffing roving machine was exhibited at Tonghe textile machinery Weaving Co., Ltd.

It uses endpoint protection technology. When the external power grid suddenly fails, the motors can still be stopped according to normal steps, effectively preventing the details and breakage caused by roving, and the automatic exchange of full and thin pipes in the thick and thin exchange area is reliable and correct.

Important development position of new spinning equipment

The textile machinery industry "12th Five-Year" development guidance points out that during the "12th Five-Year" period, the textile machinery industry's scientific and technological research and industrialization projects include the automatic rotor spinning machine and the jet vortex spinning machine. These products have already been developed at home, but the sales volume of the market is not large.

In the future, these devices will become an important position in the development of the industry.

At the China International Textile Machinery Exhibition and ITMA Asia Exhibition held this year, Lida exhibited a new automatic rotor spinning machine R60, which set up a new standard for quality, output and flexibility. The machine energy consumption was further reduced, the production capacity increased by 5%, and the yarn quality was better.

The machine has the seamless joint technology, and can get the same joint as the original yarn, so that the yarn quality is uniform.

The JWF1612 rotor spinning machine developed by Jingwei Yuci branch has the advantages of high speed, high efficiency, high quality and humanized design.

The actual speed of the machine can be ~105000 R / min at 80000 R / min, and the speed of insertion can reach 200 m / min.

In addition, the TQF368 rotor spinning machine developed by Zhejiang Titan textile machinery company is a new spinning equipment with high speed, high efficiency and automatic miscellaneous discharge. The spinning machine has the best air flow parameters, and can be adjusted according to the spinning requirements, at the same time, it can control the miscellaneous efficiency and ensure the yarn quality.

The machine has a mechatronic semi-automatic digital joint system. The control accuracy of the joint time reaches milliseconds. The stepper motor is fed separately. After breaking, the fiber bar is passed back from the combing roller not only by the return function of the motor, but also to prevent any damage to the fiber and achieve single spindle control.
