Middle cam of computerized flat knitting machine

Abstract

The invention discloses a middle cam of a computerized flat knitting machine, which comprises a third rail and a fourth rail used for tucking and receiving, wherein the third rail and the fourth rail are splayed and laterally pass through a body. Middles of the two rails form a middle groove, a limiting groove is arranged right below the middle groove, and a swing cam is arranged in the limiting groove and positioned by a center hole which is arranged on the center line of the body. A fourth left inclined groove, the left slope of the swing cam, a third right slope and a third right inclined groove form a one-way needle passing rail c, and other portions form a one-way needle passing rail d correspondingly. A step is arranged on the inner lower portion of the fourth left inclined groove so that an upper inner space of the fourth left inclined groove allows a combined needle butt to slide out, and the height of the step is smaller than the depth of the fourth left inclined groove. The step and a wide inlet of the fourth left inclined groove are in connection through a slope. Slipping of the needle butt is limited while sliding out is convenient during knitting, sliding in of the needle butt is facilitated, sliding of the needle can be more smooth, and operation of the computerized flat knitting machine can be more stable.

Description

technical field [0001] The invention relates to a computerized flat knitting machine, in particular to a Zhongshan triangle of a computerized flat knitting machine. Background technique [0002] The computerized flat knitting machine is the most common machine in the knitting field, and the triangle part of the machine head is a key component of the computerized flat knitting machine, which is generally assembled on the triangle bottom plate. In the past flat knitting machines, the Zhongshan triangle is composed of a movable triangle and a fixed triangle, and the movable triangle is controlled by some electrical equipment. When starting computer knitting, according to the needs of pattern technology, the movable triangle needs to do some switching actions, and some corresponding pressing pieces also need to change the position, and whether it is triangle switching or pressing piece position changes, it must be assisted flexibly The mechanism is completed under the control o...

AI Technical Summary

Problems solved by technology

[0003] The existing Zhongshan triangle has the following defects in the process of use: 1. Many transmission mechanisms and electric drive devices must be arranged behind the triangle bottom plate and the jacquard triangle bottom plate, which increases the weight and production cost of the flat knitting machine, and has higher requirements for the manufacture and assembly of parts , leading to high manufacturing costs and installation difficulties, and inconvenient maintenance; 2. Due to the complex structure, affected by mechanical wear, electrical control failure, or other factors such as hair dust, oil pollution, etc., the triangular action is often insensitive, not in place or even Stuck phenomenon occurs; 3. The triangular action is not in place, so that the knitting needle can not go back, bend and knit normally, and the phenomenon of needle hitting or missing needles will cause the flat knitting machine to fail to work normally, the production efficiency is not high enough, and the failure rate is high. , which reduces the weaving effect of the equipment and affects the user's production

[0005] But, above-mentioned technical scheme, comprise in the technical scheme of other Zhongshan triangle in the prior art, because the 4th left and right chute do not have protection design, the needle clock of combined needle is running along the one-way needle track c, d to connect. During needle knitting, due to the large openings on both sides, the needle bell is easy to slip off, causing needle movement errors, which will affect the operation of the flat knitting machine
