Description

Needle plate inserting piece of braiding machine

Technical Field

The utility model relates to the technical field of knitting machines, in particular to a needle plate inserting piece of a knitting machine.

Background

As is known in the art, the tabs on knitting machines are typically mounted on needle plates that form needle slots for the needles to be inserted. When the knitting machine works, the knitting needles stretch along the needle grooves by the driving of the triangular mechanism, thereby finishing the knitting work of fabrics.

In order to shorten the needle pitch of adjacent knitting needles, the current common practice for needle plate insertion in a dense needle knitting machine is to mill symmetrical abdicating grooves 101 on two side walls of the front part of an insertion piece 100 respectively as shown in fig. 1, and change the original mode that only one knitting needle can be placed in one needle groove into the mode of installing two knitting needles to increase the number of knitting needles per inch on the needle plate so as to achieve the purpose of shortening the needle pitch.

Although the number of the knitting needles is increased and the needle pitch of the adjacent knitting needles is shortened, the width of the abdicating groove 101 is easy to control when the abdicating groove 101 is machined, but the position on the inserting sheet is difficult to grasp, so that the position of the abdicating groove 101 on each inserting sheet 100 has machining errors, namely, some abdicating grooves 101 are machined upwards, and some abdicating grooves are machined downwards. Even if the machining error is relatively small, the following technical problems still exist during subsequent assembly:

1. if the processing of the abdicating groove is deviated, after the inserting sheet 100 is loaded into the inserting sheet groove on the needle plate, the knitting needle in the abdicating groove 101 is pressed by the surface of the needle plate, so that the knitting needle can not perform telescopic motion in the abdicating groove 101;

2. if the processing of the abdicating groove is deviated upwards, after the inserting sheet 100 is loaded into the inserting sheet groove on the needle plate, the knitting needle will swing in the gap reserved by the abdicating groove 101, thereby affecting the assembly and operation precision of each knitting needle.

Therefore, no matter how to process the abdicating groove 101, the technical problem is existed, so that the knitting machine can not ensure the yarn looping consistency at all when working, and further the flatness and the planeness of the knitted fabric are directly influenced, and the requirement of high quality is difficult to achieve.
