Jacquard needle block for warp knitting machine

Abstract

The invention discloses a jacquard needle block for a warp knitting machine, which comprises a supporting seat which is formed by detachably connecting a baseplate, a needle inserting block and a limit block, wherein the needle inserting block is a plastic piece; the front side face of the needle inserting block is provided with a U-shaped groove in the left and right direction; the fronts of theupper and lower surfaces of a needle inserting block are provided with an arc upper positioning protrusion and an arc lower positioning protrusion; a part of the needle inserting groove into which a jacquard needle is inserted is provided with a positioning sleeve which is a plastic piece; the left and right side faces of the positioning sleeve are provided with an upper positioning edge and a lower positioning edge; and jacquard needles are positioned on the rear sides of the upper and lower positioning protrusions of a side needle inserting block through the upper and lower positioning edges on the two sides of the positioning sleeve, and are respectively pressed on the upper and lower surfaces of the side needle inserting block so as to be fixed in the needle inserting groove of the needle inserting block. The supporting seat is an assembly; the baseplate, the needle inserting block and the limit block are convenient to machine; and the limit block serving as a wearing part is replaced by only detaching screws, and a jacquard guide needle is only pulled out and replaced, so that the wearing parts are convenient to replace.

Description

technical field [0001] The invention relates to a jacquard needle block for a warp knitting machine. Background technique [0002] The jacquard needle block of the warp knitting machine includes a support seat and a jacquard guide needle. The bottom plate of the support seat is provided with an inlay block and a limit block. The inlay block and the limit block are respectively provided with a longitudinal inlay groove and a longitudinal Limiting groove, a jacquard needle is embedded in the needle groove of each needle block and the limiting groove of the corresponding limiting block. The jacquard guide needle has an intermediate carrier, a guide needle and piezoelectric sheets arranged on both sides of the intermediate carrier. The piezoelectric sheet of the jacquard needle is generally a ceramic piezoelectric sheet at present. The ceramic piezoelectric sheet receives a voltage signal and passes through The bending deformation drives the guide needle to make a warp gauge of...

AI Technical Summary

Problems solved by technology

The above-mentioned jacquard needle block has the following disadvantages: ①. The support seat is an integral special-shaped part, so high requirements are placed on the processing of the support seat, and the processing cost is relatively high

②.Because the needle head of jacquard jacquard needle deviates in the limit groove of the limit block and rubs against the inner wall of the limit groove, the limit block is easy to wear. Once the limit block is worn out as a wearing part, it needs to be repaired Needle blocks are replaced as a whole, resulting in serious waste

Although the above operation can reuse the jacquard needle block, it is still very troublesome to replace a single jacquard guide needle
