Vertical loop-transferring jacquard control mechanism of round knitting machine

Abstract

The invention discloses a vertical loop-transferring jacquard control mechanism of a round knitting machine. The vertical transferring jacquard control mechanism comprises an upper needle dial, a reset triangular component, an upper loop-transferring working triangular component, an upper jacquard sheet, knitting needles, a weft nozzle, a lower loop-transferring working triangular component, a middle needle, a lower jacquard sheet, a needle selector, a lower needle dial, needle protecting plates and two groups of needle opening tongue pieces; the knitting needles include an upper knitting needle and a lower knitting needle; the needle protecting plates are arranged on the outer edge of the upper needle dial and the lower needle dial so as to ensure stable sliding of the knitting needle; two groups of needle opening tongue pieces are located at the needle lifting place of the weft nozzle, and a group of needle opening tongue pieces are used for opening the needle tongue of the upper knitting needle to perform the next turn of weaving; the other group of needle opening tongue pieces are used for opening the needle tongue of the lower knitting needle to perform the next turn of weaving. The knitting needle is stable and smooth in running, small in transfer bias, long in service life, suitable for many patterns, accurate in needle selection, high in output, and good in textile quality.

Description

technical field [0001] The invention relates to the technical field of circular knitting machines, in particular to a circular knitting machine up and down transfer jacquard control mechanism. Background technique [0002] The existing circular knitting machine utilizes the upper knitting needle and the lower knitting needle to complete double-sided embroidery. In order to enable the latch of the knitting needle to be opened reliably, a needle opening piece is usually provided, but the existing needle opening piece is usually Fixed setting, it is easy to have a rigid collision with the needle hook of the knitting needle and cause damage to the knitting needle, which not only wastes resources, but also reduces work efficiency, and the upper and lower transfer cams of the existing circular knitting machine are usually unchanged Yes, the patterns that can be used are limited.

Problems solved by technology

[0002] Existing circular knitting machines use the upper knitting needle and the lower knitting needle to complete double-sided embroidery. In order to enable the latch of the knitting needle to be opened reliably, a needle opening piece is usually provided, but the existing needle opening piece is usually Fixed setting, it is easy to have a rigid collision with the needle hook of the knitting needle to cause damage to the knitting needle, which not only wastes resources, but also reduces work efficiency, and the upper and lower transfer cams of the existing circular knitting machine are usually unchanged Yes, the patterns that can be used are limited

[0003] The connection between the existing jacquard sheet and the upper transfer cam is through two stitches, which go in and out at the same time as the knitting needles. During the assembly process of the knitting needles, the jacquard sheet and the knitting needles need to be assembled first. Well, put it on the dial, and then connect it with the needle groove of the upper transfer triangle to achieve the transfer action. This structure is time-consuming and expensive to assemble, and because the connection relationship between the jacquard piece and the knitting needle is a point-to-point relationship, In the knitting process, it is easy to slip, not smooth, and the service life is short. Therefore, there is an urgent need for a knitting needle that runs smoothly, has small transmission errors, and has a long service life.
