Abstract

The utility model relates to the field of precious metal wire mesh knitting, in particular to a back stitching triangle for a metal wire mesh knitting machine. The problem that an existing knitting machine back stitching triangle is not reasonable in structural design, wires can be easily broken by being pulled, holes are formed in a mesh face, and production loss and cost are increased is solved. The back stitching triangle comprises a back stitching triangle body fixed on a needle cylinder table. A back stitching inlet is formed in the upper portion of one side of the back stitching triangle body, and a back stitching outlet is formed in the lower portion of the other side of the back stitching triangle body. A bearded needle sliding way is arranged between the back stitching inlet and the back stitching outlet. A back stitching groove which is in arc transition with the bearded needle sliding way is formed in the back stitching outlet. The included angle alpha between the connecting line of the lowest point and the highest point of the back stitching groove and the horizontal direction is 50-53 degrees. The height H between the highest point of the back stitching groove and the lower end of the back stitching triangle body is 20-25mm. A bearded needle can be separated from a knitting zone timely and normally during back stitching, a large number of wire breaking phenomena are reduced, production loss is lowered, the improved structure is simple, design is ingenious, and certain popularizing and using value is achieved.

Description

Woven wire knitting machine back-stitching cam

Technical field

The utility model relates to noble metal silk screen braiding field, is specially a kind of woven wire knitting machine back-stitching cam.

Background technology

At present, knitting machine is in the knitmesh process, back-stitching cam is important function corner block, Main Function is the playback height that determines crochet hook, by the height of regulating the crochet hook position, reach the purpose of smooth braiding, but existing back-stitching cam structural design is unreasonable, crochet hook often can not normally break away from knitting zone in time when back stitching, easily cause in the knitmesh process excessive to stretching wiry, often cause and break silk, make wire side form hole, have a strong impact on the woven wire quality, the wearing and tearing of crochet hook to twine in the knitmesh process, have also been increased simultaneously, formed noble metal powder, increased to produce and consumed and cost.

Summary of the invention

The utility model is unreasonable in order to solve existing knitting machine back-stitching cam structural design, easily causes to break silk, wire side and form hole and increase to produce and consume and the problem of cost, and a kind of woven wire knitting machine back-stitching cam is provided.

The utility model is to adopt following technical scheme to realize: woven wire knitting machine back-stitching cam, comprise the back-stitching cam body be fixed on the syringe platform, back-stitching cam body one side top has the back stitching entrance, the opposite side below has the back stitching outlet, between back stitching entrance and back stitching outlet, be provided with the crochet hook slideway, innovative point of the present utility model is to be provided with in the back stitching exit back stitching groove with crochet hook slideway arc transition, and the angle α of the line between back stitching groove minimum point and peak and horizontal direction is 50 ° ~ 53 °.

Height H between described back stitching groove peak and back-stitching cam body lower end is 20 ~ 25mm.

Adopt structural design of the present utility model, by the repeated structure to netting machine, explore, experiment, in the back stitching of back-stitching cam, export out and set up the back stitching groove, and determined line and the angle α (being the back stitching angle) of horizontal direction and the height (being that back stitching goes out open height) between back stitching groove peak and back-stitching cam body between back stitching groove minimum point and peak through test of many times, make crochet hook can normally break away from time knitting zone when back stitching, reduced a large amount of fracture of wire phenomenons, reduced to produce and consumed, and improve simple in structure, design ingenious, has certain application value.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the top view of Fig. 1;

Fig. 3 is use state diagram of the present utility model;

In figure: 1-back-stitching cam body; 2-back stitching entrance; The outlet of 3-back stitching; 4-crochet hook slideway; 5-back stitching groove; 6-syringe platform; 7-back stitching angle fixed block; The 8-bolt; The 9-crochet hook; The 10-syringe; The 11-slide block.

The specific embodiment

Woven wire knitting machine back-stitching cam, as shown in Figure 1, 2, comprise the back-stitching cam body 1 be fixed on syringe platform 6, back-stitching cam body one side top has back stitching entrance 2, the opposite side below has back stitching outlet 3, between the outlet of back stitching entrance and back stitching, be provided with crochet hook slideway 4, in the back stitching exit, be provided with the back stitching groove 5 with crochet hook slideway arc transition, the angle α of the line between back stitching groove minimum point and peak and horizontal direction is 50 ° ~ 53 °.Height H between back stitching groove 5 peaks and back-stitching cam body 1 lower end is 20 ~ 25mm.

As shown in Figure 3, during use, back-stitching cam is utilized to back stitching angle fixed block and be bolted on the syringe platform, crochet hook is plugged in the syringe relevant position, and then the slide block on crochet hook is entered, moved to the back stitching exit through the crochet hook slideway by the back stitching entrance in the knitmesh process, now, slide block on crochet hook enters in the back stitching groove, adjusts in time the position of crochet hook, makes it normally break away from timely knitting zone, reduced a large amount of fracture of wire phenomenons, reduced to produce consuming.

Claims
