Pay-off tightening device for high-performance fiber knitting machine

Abstract

The invention provides a pay-off tightening device for a high-performance fiber braiding machine, the pay-off tightening device comprises a device main body, one side of the top of the device main body is connected with an adjusting assembly capable of adjusting pay-off tightening of textile fibers, the pay-off tightening device further comprises a hydraulic push rod, and the hydraulic push rod is in transmission connection with the adjusting assembly. A plurality of strands of textile fibers are separated through a protection box in the moving assembly, the textile fibers can be protected in the moving process through moving in the protection box, the take-up speed is reduced through stable rotation of the adjusting assembly in the take-up process, the effect that take-up is stopped in time can be achieved, the situation that the textile fibers are broken due to pulling caused by inertia is prevented, and the service life of the textile fibers is prolonged. Through cooperation with the protection air bag rotating inside, the air bag can be expanded during sudden stop, textile fibers make contact with the air bag for buffering, the air bag can be slowly contracted during pay-off, and the problem that the textile fibers are too long and knotted is solved.

Description

technical field [0001] The invention relates to the field of fiber weaving machines, in particular to a pay-off and tightening device for high-performance fiber weaving machines. Background technique [0002] The braiding machine is a textile device that closely knits a variety of yarn fibers to each other according to a certain rule. It is necessary to connect the raw yarn fibers to the braiding machine to obtain the finished product. However, when the yarn fibers are unloaded, the number of fibers is large and the diameter is slender. , It is necessary to carry out a tightening device to assist the adjustment of the knitting machine. In the tightening device, two actions of pay-off and take-up are required. Pay-off is to mechanically pull the yarn fibers to form a complete pay-off section. Tightening is to tighten one end of the yarn fiber to prevent the yarn fiber from being too tight or loose, resulting in entanglement or breakage after the tension limit. [0003] In vi...

AI Technical Summary

Problems solved by technology

[0004] Because in the process of taking up the thread, because the yarn fiber is relatively thin, when the device is in the state of taking up the thread during operation, the device cannot stop in time, and the yarn fiber is easy to be pulled due to inertia when the thread is stopped, such as The continuous pulling of the device will lead to the breakage of the yarn fibers, making it difficult to connect the yarn fibers in the later stage. At the same time, the yarn suddenly becomes loose when the yarn is unwound, so that the multi-strand yarn fibers are easily entangled after drooping, resulting in troublesome handling of the yarn fibers.
