Yarn creel of multi-axis warp knitting machine

Abstract

The invention provides a yarn creel of a multi-axis warp knitting machine. The yarn creel comprises a base, a yarn shaft, a yarn retaining plate, a bearing group, a brake disc, a brake pad and a retaining ring, wherein the bearing group comprises a bearing I and a bearing II, the base sequentially penetrates through the brake disc, the yarn retaining plate, the bearing I, the bearing II and the retaining ring, the bearing II is fixed by the retaining ring, the middle part of the yarn shaft is provided with a cylindrical inner cavity, the bearing I and the bearing II are respectively embedded into the two ends of the inner cavity of the yarn shaft, a rubber ring I and a rubber ring II respectively sleeve the two ends of the yarn shaft, the exterior of the brake disc is in contact with the brake pad, and the brake pad is connected with the base. The yarn creel has the advantages that the contact between a yarn and the yarn base is blocked, and the end breaking of the yarn is prevented; the friction force between a yarn spindle and the base is reduced, the drawing and plugging drag is reduced, and each spindle of yarns is controlled by tension; the operation is convenient, the control of yarn tension is more effective, uniform and convenient, the running efficiency of equipment and the product quality are improved, the production cost is reduced, the modification difficulty is decreased, and the cost is lower.

Description

technical field [0001] The invention relates to a creel for a multiaxial warp knitting machine. Background technique [0002] As an important equipment for the production of multi-axial warp knitted fabrics, the creel is used for the extraction of fibers. But there are many problems in the existing creel. For example: the tension of the creel is unstable, the yarn is easily entangled into the support and causes end breaks, the resistance to pulling out or putting in the yarn is too large, and the sliding friction of the yarn shaft is too large, etc. These problems have affected normal production to a certain extent, reduced production efficiency, increased production costs, and reduced product quality. The specific analysis is as follows: [0003] 1. The yarn tension is unstable. After analysis, this is caused by the fact that the tension of the spindle cannot be adjusted separately. Specifically, the processing accuracy of each yarn shaft and base is not the same, a...

Problems solved by technology

[0008] The purpose of the present invention is to provide a yarn creel for multi-axial warp knitting machines to solve the problems in the prior art that the tension of the creel is unstable, the yarn is easily entangled into the support, resulting in broken ends, and the yarn is pulled out or put in too much resistance. Problems such as large, excessive sliding friction of the yarn shaft, etc.
