Knitting cam system of electric control automatic flat-knitting machine

Abstract

The invention discloses a knitting triangle system of an electronic control automatic flat knitting machine which belongs to the textile machinery technique field. The system includes a triangle bottom plate, a needle selection triangle area A and a knitting triangle area B on the triangle bottom plate. The system has characteristics that a pushing rod triangle is fixed installed on the knitting triangle area B of the triangle bottom plate, the pushing rod triangle has a push rod surface and a received ring press needle surface, a hoop pushing rod triangle is next to a pushing rod surface of the pushing rod triangle and is installed on the triangle bottom plate, the hoop pushing rod triangle can be flexible moved on the triangle bottom plate, a hoop pressing needle triangle is fixed on the triangle bottom plate of the hoop pushing rod triangle upper. The system provided by the invention has reasonable design, compact structure, high working stability, and can increase running speed for reducing fault and increasing product.

Description

technical field [0001] The invention relates to a knitting cam system of an electronically controlled automatic flat knitting machine, which belongs to the field of manufacturing supporting parts of textile machinery. Background technique [0002] In the flat knitting machine manufacturing technology at home and abroad, high-end computer-controlled flat knitting machines using four-section needles (knitting needles, stitches, and spring stitch selectors) are quite mature, but the mechanism is complicated and the cost is high. For this purpose, a low-cost, simple computer-controlled flat knitting machine is developed by using two-section needles (knitting needles and needle selectors) to replace a large number of hand-operated flat knitting machines. However, the structure of the original two-stage needle-triangular system mostly adopts the following Figure 5 As shown in the form, it consists of two parts: the needle selection area A' and the knitting triangle area B' instal...

Problems solved by technology

However, the structure of the original two-stage needle-triangular system mostly adopts the following Figure 5 As shown in the form, it consists of two parts: the needle selection area A' and the knitting triangle area B' installed on the triangular bottom plate 1', and the left flat stitch panel 4' is fixed in the needle selection area A', and the right flat stitch The paneling is 5', the stitching cam 6' is retractable and movable: the left cam 7', the right cam 8' and the jacking cam 14' are all installed in the needle selection area A', through the left Needle cam 7', right-starting cam 8' and needle-lifting cam 14' are used to control the movement of the knitting needles, and cooperate with the loop-shifting and lifting cam 15' to complete the work of loop forming and loop transfer, but the computer controls the horizontal The machine has the following defects: 1. Since the needle lifter cam 14' is designed in the needle selection area A', the entire movement of the knitting needle rising in the needle selection area A' is all borne by the needle selection piece

In the design of the two-stage needle, there is a potential instability in the suspended movement of the needle selector in the needle groove, and this instability affects the increase in machine speed; 2. In the existing simple two-stage needle flat knitting machine Needle-lifting cam 14' all use linear needle-starting cams, and because the needle-lifting cams are all designed in the needle selection area, in order to avoid work conflicts during loop transfer, they must quit working, which causes the following disadvantages: a. Linear needle-starting The increase of the initial impact force of the triangle on the heel of the selector piece is an important factor causing the heel to be broken

b. The working stroke of the needle selector is greatly increased, and the control parts are added, which reduces the working stability of the flat knitting machine, increases the cost, and affects the increase of the machine speed.
