Crocheting fancy twisting machine

Abstract

The invention discloses a crocheting fancy twisting machine, and belongs to the field of textile machines. The crocheting fancy twisting machine comprises a transmission device, a controller, a yarn break automatic stop device, a plurality of crocheting heads and a plurality of winding and yarn guiding devices. The crocheting heads are connected with the transmission device through a first transmission belt, the winding and yarn guiding devices are connected with the transmission device through a second first transmission belt, and the controller is electrically connected with the transmission device, the winding and yarn guiding devices and the yarn break automatic stop device. According to the crocheting fancy twisting machine, the mechanical structure is simplified, one motor drives the multiple crocheting heads and the multiple winding and yarn guiding devices to work through a tangential belt in transmission mode, and therefore cost and energy are saved; rotation of the crocheting heads and the winding and yarn guiding devices is flexibly controlled by independent electromagnetic clutches, the transmission structure is reasonable, operation is easy, convenient and flexible, and production efficiency is improved; the internal structures of the crocheting heads are changed, an adjustable end cover can be rotated by loosening locking nuts of the adjustable end cover, and the working gap between an upper cam and a lower cam can be adjusted in real time to the optimal state.

Description

technical field [0001] The invention belongs to the field of textile machinery, and more specifically relates to a hook knitting fancy twisting machine. Background technique [0002] In recent years, the production of fancy yarns, threads, silks and tapes in my country has increased exponentially, and its application fields have gradually moved from knitted garments to home textile decorations. Since the home textile industry is a new industry, fancy yarn is an indispensable raw material in the design of home textile products, and has a wide range of applications in home textile decoration products. [0003] However, most of the equipment for producing fancy yarns on the market is hollow spindle fancy twisting machine, followed by computerized crochet machine, chenille machine, 12-needle, 24-needle needle cylinder machine and roving machine transformed belly Yarn frames, slub yarn machines and other fancy thread production machines transformed from spinning frames are mostl...

AI Technical Summary

Problems solved by technology

[0003] However, most of the equipment for producing fancy yarns on the market is hollow spindle fancy twisting machine, followed by computerized crochet machine, chenille machine, 12-needle, 24-needle needle cylinder machine and roving machine transformed belly Yarn machines, fancy thread production machines such as slub yarn machines transformed from spinning frames, are mostly for processing and producing multi-needle threads, and the quality and output of products produced by improved machines also have certain limitations.

[0004] Existing twisting machines generally use crochet shell transmission, each winding spindle is equipped with a motor, and the crochet head is driven by a single motor spindle, which is costly and consumes a lot of power; when the yarn breaks and needs to be shut down, The crochet head and the winding spindle cannot be stopped synchronously, which affects productivity, easily damages parts, and leads to safety accidents; at the same time, there are high surface roughness of the crochet cam, misalignment of the upper and lower curves of the cam, and needle blocking when the latch needle runs at high speed. The crochet head uses guide grooves and positioning screws to control the position of the cam. Due to the existence of gaps, it is difficult to align, and the needle is easily displaced. Long time and other issues

At present, the production technology of processing fancy threads by means of crochet in the market is not mature enough, so to a certain extent, it limits the development of the decorative products industry.
