Shredding device used for recycling polyester short fiber

Abstract

The invention provides a shredding device used for recycling polyester short fibers, and belongs to the technical field of recycling polyester short fiber spinning. The device comprises a tool apron, two round cutters, and a piston rod, and a piston. One round cutter is in a hollow cylindrical shape, and is fixed in the tool apron. The left end of the round cutter is a cutting edge. The other round cutter is in a solid cylindrical shape, and is fixed on the piston rod. The hollow cylindrical round cutter is the guide sleeve of the solid cylindrical round cutter. The middle of the solid cylindrical round cutter is provided with an arc gap, the left end of the gap is a cutting edge, and the outer wall of the tool apron is provided with a gap. The arc gap and the gap form a silk channel. The device is characterized by also providing with a yarn breaking detector used to detect broken yarns. The yarn breaking detector is arranged in the tool apron gap. The device is advantaged by broken yarn detection, full automatic shredding, rapid and accurate operation, long in service life, and is safe and reliable.

Description

technical field [0001] The invention specifically relates to a shredding device for regenerated polyester staple fiber with a broken wire detector, which is used on a regenerated polyester staple fiber winding machine and belongs to the technical field of regenerated polyester staple fiber spinning. Background technique [0002] In the production process of recycled polyester staple fiber spinning, when the floating yarn, spinning head, winding roller and equipment behind the winding machine (such as haul-off machine, feeding machine, and reciprocating machine for the silk barrel) fail, the process requires that the yarn The tow is cut before the haul-off machine, and then the cut tow is wound on the waste silk roller, or the waste silk is sucked away by the waste silk suction nozzle. At present, the manual operation method is generally adopted. After the operator sucks the tow with a suction gun, the tow is quickly cut with ordinary scissors. There is following shortcoming...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: First, the labor intensity is high, the operation requirements are high, and the action must be very fast and accurate

As the tow speed is as high as 1300m / min, the allowable operating time is very short, and the operation proficiency is required to be very high; secondly, the first-time success rate of the operation is very low, resulting in prolonged troubleshooting time and increased waste silk

Especially in a large-capacity production line, when the number of spinning holes reaches more than 3000 holes, the denier of the tow is very large, and manual operation is quite difficult; third, it is easy to damage the malfunctioning equipment and induce safety accidents
