Computer flat knitting machine with pre-traction mechanisms of guide rail of yarn guide

Abstract

The invention discloses a computer flat knitting machine with pre-traction mechanisms of a guide rail of a yarn guide. The computer flat knitting machine comprises the guide rail of the yarn guide, wherein the yarn guide is slidably arranged on the guide rail of the yarn guide, and the pre-traction mechanisms are arranged at one end or two ends of the guide rail of the yarn guide and stretch the guide rail of the yarn guide to lead the guide rail of the yarn guide to keep straight. Pre-traction is exerted on the guide rail of the yarn guide to lead the guide rail of the yarn guide to parallely, stably and accurately send weaving yarns into a knitting needle hook for knitting along the straight guide rail of the yarn guide during knitting operation under the effect of pre-traction, and normal large-strength knitting of the guide rail of the yarn guide is ensured.

Description

technical field [0001] The invention relates to a computerized flat knitting machine, in particular to a computerized flat knitting machine with a yarn guide rail pre-gravity mechanism. Background technique [0002] With the rapid development of computerized flat knitting machines, there are new requirements for the development of the original models, and super-long, multi-head, and wide-width knitting have become the development trend. [0003] The left and right sliding work of the yarn guide is carried out on the guide rail of the yarn guide, and the length of the guide rail of the yarn guide determines the model length of the computerized flat knitting machine. The existing guide rails of the yarn guide are fixed on the guide rail brackets at both ends thereof. When the span of the guide rails of the yarn guide is constant, the rigidity of the guide rails of the yarn guide can overcome its own gravity and the influence of the yarn guide to keep straight. [0004] When t...

AI Technical Summary

Problems solved by technology

This is because: the yarn guide rail must be parallel to the straight line so that the yarn guide carriage can carry the yarn into the needle hook of the knitting needle for knitting without error, and the yarn guide rail can be extended after the yarn guide rail The span will increase, and its own rigidity is certain. When its own weight increases, the guide rail of the yarn guide will be deformed under the action of gravity, and the head drives the yarn guide on the yarn guide. Due to the continuous back and forth operation on the guide rail, the parallel straightness of the guide rail of the yarn guide cannot be guaranteed, which affects the normal weaving work
