Technical Field

The utility model relates to the technical field of knitting machines, in particular to a high-speed knitting machine and a knitting needle thereof.

Background

The knitted fabric has the advantages of good elasticity, wide application and the like. The production principle of knitting machine is that knitting needle is used to bend yarn into loop by means of the constraint of runway on triangle, after the loop is formed, the formed loop is pushed out of loop forming position by sinker so as to leave working position to start secondary loop forming. The traditional knitting machine, the sinker and the needle groove or the inserting piece on the needle cylinder form a pair of friction pairs, and under the action of other components, the sinker slides back and forth in a friction way to finish the loop withdrawal action, so that the loop withdrawal mode is large in abrasion, and the running speed of the equipment is limited in order to avoid burning yarns at too high machine temperature caused by friction.

The knitting needle is a main looping machine part on a knitting machine, is made of steel wires or steel belts through mechanical processing, is one of key equipment of the knitting machine, and is used for knitting yarns into loops and connecting loop strings into knitted fabrics, and the structure and the shape of the knitting needle influence the knitting looping process, and when the weaving structure of the knitting machine is changed, the productivity and the quality of products are improved. The outer dimensions of the needles of the knitting machine structure vary, the type of knitting machine that is suitable varies, and the fabric produced varies.

Detailed Description

In order to further explain the technical scheme of the utility model, the utility model is explained in detail by specific examples.

As shown in fig. 1 and 2, the utility model discloses a high-speed knitting machine, which comprises a loop withdrawing structure and a knitting needle 6, wherein the loop withdrawing structure comprises a sinker 1, a loop withdrawing cam 2, an adjusting cam 3, a resetting cam 4 and a needle cylinder 5, the knitting needle 6 is arranged in the needle cylinder 5, the sinker 1 comprises a loop withdrawing opening 11, a loop withdrawing heel 12, an adjusting heel 13, a resetting heel 14 and an arc swinging fulcrum 15, the loop withdrawing opening 11 is arranged at the front end of the sinker 1 and is used for pushing yarns out, the resetting heel 14 is arranged at the rear end of the sinker 1, the loop withdrawing heel 12 is arranged behind the loop withdrawing opening 11 at intervals, the adjusting heel 13 is arranged between the loop withdrawing heel 12 and the resetting heel 14 at intervals, the loop withdrawing opening 11, the loop withdrawing heel 12, the adjusting heel 13 and the resetting heel 14 are arranged at the same side of the sinker 1, the arc swinging fulcrum 15 is arranged on the other side of the sinker 1 and is positioned between the withdrawal heel 12 and the reset heel 14, the withdrawal heel 12 is arranged on the withdrawal cam 2, the adjustment heel 13 is connected with the adjustment cam 3, the reset heel 14 is arranged on the reset cam 4, the needle cylinder 5 is in a circular ring shape, a groove is arranged on the needle cylinder, the arc swinging fulcrum 15 is in contact with the bottom of the needle cylinder 5, the withdrawal cam 2 and the reset cam 4 are convex cams, the strokes of the withdrawal cam 2 and the reset cam are opposite, namely, when the withdrawal cam 2 is at a high point, the reset cam 4 is at a low point, and when the withdrawal cam 2 is at a low point, the reset cam is at a high point, so that the withdrawal heel 12 and the reset heel 14 of the sinker 1 are acted, and the sinker 1 swings by taking the arc swinging fulcrum 15 as a fulcrum. The adjusting triangle 3 is a groove cam, the groove on the adjusting triangle 3 is changed according to production requirements, namely, the runway track of the adjusting triangle 3 is changed, and then the sinker 1 can be controlled to move in the vertical direction by matching the loop-withdrawing triangle 2 with the reset triangle 4, so that the swing amplitude of the sinker 1 is changed.
