Description

Technical Field

[0001] This invention relates to a needle plate assembly for a horizontal knitting machine that prevents the needles from wobbling after exiting the machine. Background Technology

[0002] Currently, when knitting on a horizontal knitting machine, there is no sufficient pressure gap between the needles. When the needles turn over and come out, there is a lot of wobbling, which affects the stability of the stitching.

[0003] High-end flat knitting machines, especially fine-gauge flat knitting machines, knit expensive fabrics. Even a slight missed stitch in the stitching can lower the quality of the knitted sweater. Even if it is repaired manually, the cost of labor increases due to the current labor shortage. Against this backdrop, it is necessary to improve the precision of existing needle plate components. To promote the progress of the flat knitting machine industry—especially the stability of fine-gauge flat knitting machines—continuous improvement and innovation of the needle plate components of flat knitting machines are required. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to design a needle plate assembly for a horizontal knitting machine that avoids the shaking of the needle after it comes out of the machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a needle plate assembly for a horizontal knitting machine that prevents the needle from shaking after exiting the machine, comprising a pressure bar, inserts, a needle plate, a knitting needle, and a dovetail stopper. The insert slot of the needle plate is provided with inserts arranged in sequence, and a needle groove is formed by two adjacent inserts. The knitting needle is placed in the needle groove. The pressure bar is placed in the needle groove located above the knitting needle. The lower end of the pressure bar is provided with a pressure surface for fitting the upper end face of the knitting needle. The pressure bar is provided with a groove for fitting the dovetail stopper. A first wire hole is provided on the rear side of the pressure bar. The inserts are provided with a stepped surface that extends beyond the first wire hole at the location corresponding to the first wire hole.

[0006] Furthermore, a raised second extension is provided on one side of the groove of the pressure needle strip, and a first groove is provided at the dovetail plug corresponding to the insert strip. A raised third extension is provided in the first groove, and the third extension is higher than the second extension.

[0007] Furthermore, the front side of the pressure bar is provided with a first extension section for inserting into the notch of the sinker plate in the horizontal knitting machine.

[0008] Furthermore, the pressure needle surface is an inclined pressure needle surface that gradually slopes downwards from the rear to the front.

[0009] Furthermore, the back of the pressure bar is provided with a connecting structure for the corresponding knitting needle selection foot.

[0010] Furthermore, the upper end of the first extension is a forward-sloping surface.

[0011] Furthermore, the needle plate has a plurality of first insert slots and second insert slots arranged at equal intervals. The first inserts are installed in the first insert slots, and the second inserts are installed in the second insert slots, arranged in a 1-every-1 configuration in the insert slots of the needle plate. The front end of the insert group consisting of the first inserts and the second inserts is limited by insert positioning wires. Each pair of adjacent first inserts and second inserts forms two adjacent needle slots, including an adjacent first needle slot and a second needle slot. One needle is placed in each of the first needle slot and the second needle slot. The knitting needles consist of two mirror images of each other, arranged in a 1-alternate configuration. The dividing line between the two needles corresponds to the second insert. A toothed plate is placed at the upper opening of the first insert slot. The first and second insert slots are assembled in a 1-alternate combination. A sinker is installed in the sinker installation notch of the second slot. A pressure bar is installed in the needle groove formed by the first and second inserts, and is limited and fixed by a dovetail plug passing through the corresponding grooves at the upper ends of the first, second, and pressure bars. A steel wire passes through the first wire hole and is placed on the stepped surface.

[0012] Furthermore, during installation, the stepped surface of the insert plate mounted on the needle plate is ground flat according to the position of the first wire hole, and the dust is cleaned after reaching the position of the first wire hole.

[0013] Furthermore, during installation, the third extension of the insert plate mounted on the needle plate is flat-ground according to the position of the second extension, and then the dust is cleaned.

[0014] The advantages are: it solves the problem of low precision and easy needle wobbling caused by errors between the wire hole of the insert and the first wire hole in the existing technology, and achieves the effect that the stepped surface and the first wire hole can be precisely matched through the wire; it solves the problem that the needle can easily wobble up and down when the dovetail plug passes through the first groove of the insert and the groove of the pressure strip due to errors between the first groove and the groove, and achieves the effect that the third extension section and the second extension section can be precisely matched through the dovetail plug.
