Improved head cam system for computerized flat knitting machine

Abstract

The invention relates to the technical field of knitting machines, and particularly discloses an improved head cam system for a computerized flat knitting machine and a knitting needle device of the computerized flat knitting machine, comprising at least a knitting unit. Each knitting unit comprises a cam bottom plate, the middle part of the cam bottom plate is provided with a needle cushion guide rail, one side of the needle cushion guide rail is provided with a needle selection sheet rear guide block, and the other side of needle cushion guide rail is provided with a left density cam and a right density cam, a stitch cam is arranged between the left and the right density quality cams and provided with an external needle track and an internal needle track, and an inlet and an outlet of the external needle track are arranged into stitch guide blocks; a raising cam is arranged between the stitch cam and the needle cushion guide rail and embedded with a tucking guide block, the stitch guide block and the tucking guide block are connected to form a whole body; an inlet and an outlet of the internal needle track are provided with loop transfer guide blocks; and the needle cushion guide rail is provided with an intermediate sheet knit stitch guide block, and a needle selection sheet front guide block is arranged between the needle cushion guide rail and the needle selection sheet rear guide block. The cam system has a simple structure, low manufacture cost and high working efficiency, and is reliable in running.

Description

technical field [0001] The invention relates to the technical field of knitting machinery, in particular to an improved head cam system of a computerized flat knitting machine. Background technique [0002] The cam system of the computerized flat knitting machine in the prior art generally has the following deficiencies: [0003] 1. The computerized flat knitting machines currently on the market generally use multi-section needle selection (more than six sections), and there are many movable triangular pressing pieces, the mechanism is complicated, and the probability of malfunction and failure is also high. Once a mistake is made, it will affect the pattern and quality of the braid. [0004] 2. Because it is a multi-section needle selection, it adopts a large number of needle selection jacks (six types for six sections, eight types for eight sections, and ten types for ten sections), and the assembly is cumbersome. [0005] 3. Due to the multi-stage needle selection, it n...

AI Technical Summary

Problems solved by technology

[0003] 1. The computerized flat knitting machines currently on the market generally use multi-section needle selection (more than six sections), and there are many movable triangular pressing pieces, the mechanism is complicated, and the probability of malfunction and failure is also high.

Once a mistake will affect the pattern and quality of the braid

[0004] 2. Due to the multi-stage needle selection, it uses more needle selection pieces (six types for six segments, eight types for eight segments, and ten types for ten segments), and the assembly is cumbersome

[0005] 3. Due to the multi-stage needle selection, it needs to install more needle selection electromagnets (forty-eight for the six-stage dual system, and sixty-four for the eight-stage), the control circuit is quite complicated, there are many lines, and the manufacturing cost is high.

Then the machine head runs from right to left, and the last two needle selectors of the machine head needle selection system work to perform preliminary selection for the first line of formal knitting according to the needle selection set by the flower board. The work of the computerized flat knitting machine in the prior art low efficiency
