Machine head structure of knitting flat machine

Abstract

A head structure of flak knitting machine features that on the base plate of its front and back heads there are central jacquard cam, fixing cam, needle raising cam, big knit cam, leaf and right herringbone cams, return cam, movable kit cam and regulation mechanism for generating different densities and varying pattern.

Description

Technical field: [0001] The invention relates to the technical field of flat knitting machines, in particular to a head structure of a flat knitting machine. Background technique: [0002] The flat knitting machine is one of the commonly used mechanical equipment in the knitting industry. The head of the flat knitting machine is equipped with a central jacquard cam, a fixed cam, a needle starting cam, a large yarn bending cam, left and right herringbone cams and a back stitch cam. Among them, the large yarn bending triangle can slide up and down along the outer surface of the left and right herringbone triangles to control the degree of yarn bending, the shape and size of the new loop during the loop forming process (that is, the fabric density), and whether to withdraw the loop and the degree of the loop. , a tuck can be formed when the circle is not retreated. The bending triangle of this machine head has only one layer. When the machine head moves on the needle bed, it c...

AI Technical Summary

Problems solved by technology

The bending triangle of this machine head has only one layer. When the machine head moves on the needle bed, it cannot simultaneously drive the high-heel needles and low-heel needles on the needle bed to participate in the knitting process. Only one density can be produced in one knitting row. coils, so it is impossible to form a changing pattern

[0003] The triangular bottom plate and machine feet on the head of the existing flat knitting machine are easy to wear after being used for a period of time, so that the gap between the triangular bottom plate and the needle bed of the knitting machine, and the gap between the machine foot and the guide rail of the needle bed of the knitting machine become larger, while the existing The hand knitting machine cannot adjust it, which will easily cause the knitting machine to not work properly

[0004] The movements of the corresponding central jacquard triangles on the front and rear heads of the existing flat knitting machine are exactly the same, they rise together when they want to rise, and fall together when they want to fall, so that the knitting pattern is limited. Or fish scale pattern, it can only be achieved by arranging the high and low pins in order, which is quite inconvenient to use

[0005] In addition, the adjustment of the bending triangle on the head of the existing flat knitting machine is very cumbersome, and the accuracy of the adjustment is poor, which makes the density of knitted fabrics uneven
