Knitting system for computerized flatbed knitting machine

Abstract

The invention discloses a knitting system for a computerized flatbed knitting machine, which comprises stitch cams, a stitch transfer cam and a knitting cam, wherein a knitting rail and a stitch receiving rail are arranged on the surface of the knitting cam; the stitch transfer cam and the knitting cam are bilaterally symmetrical; a symmetry axis of the stitch transfer cam is superposed with that of the knitting cam; the stitch transfer cam and the knitting cam are fixedly arranged on a triangular mother board; the stitch transfer cam is arranged above the knitting cam; the bottom side of the stitch transfer cam is in a W shape; an opening is formed at the center above the knitting rail of the knitting cam; a stitch transfer guiding rotor is arranged in the center of the knitting camp; two sides of the rotor are crossed at the lower end to form an acute angle; the rotor can rotate around the self rotating shaft within limiting blocks at two sides of the rotor; and the two stitch cams are respectively arranged at two sides of the knitting cam. According to the knitting system disclosed by the invention, the manufacturing cost is reduced, the accessibility of the computerized flatbed knitting machine is improved and the fault rate of the knitting system is reduced.

Description

technical field [0001] The invention belongs to the technical field of knitting machines, and in particular relates to a knitting system of a computerized flat knitting machine. Background technique [0002] Computerized flat knitting machine is the most widely used machine in the knitting field. It generally includes needle bed mechanism, pulling mechanism, knitting system, transmission mechanism, etc., and the knitting system is the key part. Existing computerized flat knitting machine knitting systems generally include knitting cams, transfer cams, and stitch cams. It is necessary to install the transfer cams and knitting cams in the corresponding cavity of the cam mother board. When performing transfer or knitting actions, Cooperating with a complex linkage mechanism, the electromagnet controls the switch to make the transfer cam and the knitting cam move up and down in large quantities, so as to complete the transfer action and knitting action. When yarn, dust, grease,...

AI Technical Summary

Problems solved by technology

When yarn, dust, grease, etc. enter the movement track of the transfer cam and the knitting cam, or these parts are rusted, the above two cams will be stuck in the cavity of the cam mother board, causing the knitting needle to strike the needle , and when the electromagnet fails, it will also cause the inability to transfer or knit

In the existing triangular mother plate, the cavities corresponding to the above two triangles must not have a large gap when they cooperate with the triangles, so that the requirements for machining accuracy are improved.

[0003] In the transfer process of existing computerized flat knitting machines, the stitches of the knitting needles need to have a single transfer track. In order to provide this transfer track for the knitting needles, it is installed on the cam The transfer cam or knitting cam on the motherboard needs to add a complete transfer track according to the transfer track, which requires higher production costs and increases the area occupied by the transfer cam and knitting cam, thereby making the cam mother board also increased dramatically in size

In addition, since the transfer action and the knitting action use two completely different needle trajectories, the positions of the knitting needles after the two actions are completed are different, resulting in the need for two completely different sets of instructions to return the knitting needles. Therefore, the computerized flat knitting machine requires a relatively complex software system, which has high production costs and has high requirements for the user's operating skills.

[0004] In addition, the needle track structure of the knitting cam on the existing computerized flat knitting machine is very complicated. The needle track is formed by stacking at least five structures such as the guide cam, which greatly increases the difficulty of production. During the process, the stitches of the knitting needles are easy to hit the relevant structures in the needle track, causing damage, breakage and other consequences, seriously affecting the economic benefits of users
