Pendulum shaft structure of wide-width high-speed warp knitting machine

Abstract

The invention relates to a swing shaft structure of a wide-width high-speed warp knitting machine. Its precision reaches IT7 level and above, and it is formed by rigid connection of several short shafts, and the rigid connection is connected by hoop. The present invention adopts the technology of breaking first and connecting later. In the process of manufacturing, the pendulum shaft is divided into several short shafts for processing, and then combined in the pendulum shaft workshop, and rigidly connected to form a whole pendulum shaft. The manufacturing difficulty and cost are greatly reduced. It can also adapt to various working environments.

Description

technical field [0001] The invention belongs to the technical field of warp knitting equipment, in particular to a swing shaft structure of a wide-width high-speed warp knitting machine. Background technique [0002] In the warp knitting equipment, the length of the pendulum shaft of the wide-width high-speed warp knitting machine needs to exceed the working width, and the length of the swing in some wide-width warp knitting machines even exceeds 7m. During the operation of the warp knitting machine, the pendulum shaft needs to swing at high speed , high precision is required. Due to its long length and high precision requirements, its manufacturing is particularly difficult and costly. The processing cost of a high-speed warp knitting machine pendulum shaft with a length of φ45 of 4800mm and an accuracy of IT7 is as high as several thousand yuan. Another important issue is that the balance shaft is made of 45-gauge steel, while the knitting needle bed of the warp knitting...

AI Technical Summary

Problems solved by technology

Because the temperature of the warp knitting production workshop is different from that of the warp knitting machine pendulum shaft installation workshop, the length of the pendulum shaft and the knitting needle bed of the warp knitting machine is different due to thermal expansion and contraction, resulting in stress. The connecting arm connecting the pendulum shaft to the bed is bent, thereby affecting the normal operation of the pendulum shaft, and even the warp knitting machine cannot produce due to the misalignment of the guide needle and the needle groove.

It is usually required that the warp knitting machine manufacturing environment and the working environment are the same, that is, the pendulum shaft installation workshop and the warp knitting machine operating workshop are controlled at the same constant temperature, however, this is difficult to achieve in practice
