main devices: cotton feeding roller, spindle head of cotton feeding roller, wallboard of cotton box, anti-winding discs, fixed bolt. Anti-winding discs are made of special material The principle of the device: After putting the raw fiber into the two rollers and rollers rotate downward, there is a small part of fiber rotate to the spindle head of roller. With the spindle head rotates, more and more fiber entangled to it, until the fiber jam the gap between the spindle head and the wallboard. And eventually the jammed fiber caused breakage and bend to the roller. With the use of anti - winding device, the fiber will be blocked outside the anti-winding disc. Since the anti-winding disc is fixed on the wallboard, and it will not rotate as the roller does. Moreover, although the fiber rotates, the fiber is free from entangle due to the fact that the anti-winding disk is covered by the disc. Therefore, the problem of roller being entangled by fiber is solved fundamentally and successfully. The device was first tested in a large spinning factory in Shandong province after it was produced. During the test, different fiber materials have been taken and the technology and design also have been upgraded constantly, we finally achieved the optimized designing scheme. The problem of fiber like acrylic filament entangling the roller has been overcame successfully, which free us from extra cleaning work, and more importantly the quality of product has been improved greatly. Staff from fist-line workers to workers in workshop and quality control department all support and praise this device. Finally, all the clean-card boxes are replaced by this kind of structure, and gradually popularized, gaining recognition by customers. This device has been adopted during the production of hopper, brining great convenience and benefits to customers though our cost increased a lot. After solving the problem of roller being entangled by fiber, we upgrade the product and advance the technology, and more importantly get over the intractable technological problem so that to improve the quality of spinning. This technique is not only suits for the new carding system, but also upgrades the old blowing carding. It is a technique worth popularizing.

Customers all support and praise this device. All the clean-card boxes are replaced by this device, brining great convenience and benefits to customers though our cost increased a lot.

This product has been recognized by customers since it was equipped with FA1712 cotton box, which increase its sales volume year by year. In the latter half of 2015, 500 units of devices have been sold with sales revenue of RMB 20 million, accounting for 20% of total product sales. There were 1000 units and RMB 40 million in 2016 totally, which advanced the promotion of our brand.

The device has been proved to be effective in filament winding problem by putting it into use of textile mills and has been recognized and praised by customers. The previously widely used wooden lining block has been completely changed by the device, which used to block the top of the roller merely rather than prevent fiber from entering into the roller from below. The principle of the device is to prevent the fiber from entering the spindle head of the roller so as to avoid winding. The device has been applied for national invention patent, and the patent is under examination and authorization.

Our company has encountered similar problems in actual production. The feeding box of FA1711 for combing system and upgraded FA1712 for traditional equipment that we used both led to breakage and bend of the roller during the process of customers’ use. This weakness has not only affected the production quality of customers, but also increased the cost of equipment maintenance, bringing about negative effect and increased service costs to our company. Our company has specially held a group to study and research in terms of the feeding cotton box and roller winding. We are determined to solve this problem for our customers and for the reputation of our products. After repeated research and testing, the company finally produced anti-winding device of feeding cotton roller. The device has been proved to be effective in filament winding problem by putting it into use of textile mills and has been recognized and praised by customers. The previously widely used wooden lining block has been completely changed by the device, which used to block the top of the roller merely rather than prevent fiber from entering into the roller from below. The principle of the device is to prevent the fiber from entering the spindle head of the roller so as to avoid winding. The device has been applied for national invention patent, and the patent is under examination and authorization.

Finish time of designing: February 4th 2015 Time of initial application: April 16th 2015

This product has been recognized by customers since it was equipped with FA1712 cotton box, which increase its sales volume year by year. In the latter half of 2015, 500 units of devices have been sole with sales revenue of RMB 20 million, accounting for 20% of total product sales. There were 1000 units and RMB 40 million in 2016 totally. Well-known enterprises like SHIJIAZHUANG CHANGSHAN TEXTILE CO.LTD recognized this new device. This product advances the promotion of our brand and the long-term development of the company.
