Description
Technical Field
The invention discloses an upper disc knitting needle track adjusting device in a double-sided circular knitting machine, and belongs to the technical field of textile equipment.
Background
A circular knitting machine is also called a weft knitting machine, and weft knitting fabric refers to a knitted fabric knitted from the transverse direction, namely the weft knitting machine makes a yarn perform transverse reciprocating motion (or circular motion) from one side of the machine to the other side of the machine, and a new knitting yarn loop can be formed by matching with the motion of a knitting needle. The weft-knitted fabric is formed by knitting a course of stitches which are connected to each other up and down in the course direction by a knitting needle. All the yarn loops of one row are knitted by one yarn, and the knitting of the yarn is completed by the needle discharging cam and the needle pressing cam, but the needle moving track of the existing needle discharging cam cannot be changed, so that the knitted fabric is single in structure and cannot be diversified.
The invention patent with publication number CN104372510B discloses a circular knitting machine upper disc triangle disassembly-free curve-changing mechanism, which comprises an upper disc triangle seat and an upper disc triangle arranged on the upper disc triangle seat, wherein the inner part and the outer part of each path of the upper disc triangle are integrated into a whole, the upper disc triangle is decomposed into a main body part and a needle pressing part according to the left-right direction, and the needle pressing part of the upper disc triangle is arranged on a sliding key; the main body part of the upper disc triangle is fixed on an upper disc triangle base and can not move, two groups of telescopic blocks which influence the knitting motion trail are arranged in the inner cavity of a track groove of the main body part, the telescopic blocks are arranged at the outer ends of telescopic rods, the telescopic rods penetrate through the upper disc triangle base, the upper part of the telescopic rods is provided with cam grooves, end face cams are arranged in the upper disc triangle base, and the end face cams are matched with the cam grooves; the side surface of the end face cam is provided with an installation process notch which is matched with the outer diameter of the upper part of the telescopic rod; the telescopic block comprises a half needle telescopic block arranged in the needle inlet direction and a needle outlet telescopic block arranged on one side of the needle outlet direction of the half needle telescopic block.
The above patent changes the position of the low position section, the ascending section and the high position section on the end cam by rotating the adjusting handle, so that the position of the half needle telescopic block and the needle outlet telescopic block also changes, so that the knitting needle presents three states of flat needle, half needle or needle outlet, but because the half needle telescopic block and the needle outlet telescopic block are controlled by the end cam, the heights of the low position section, the ascending section and the high position section are not consistent, if the adjusting handle is ensured to rotate smoothly, a transition section with gradually changed heights is necessary among the low position section, the ascending section and the high position section, so that the relative sliding between the telescopic rod and the end cam is easy to occur, the contact area of the two is also reduced, the needle outlet telescopic block or the half needle is not easy to keep stable when stressed, thereby causing the condition of unsmooth needle firing and needle outlet, and simultaneously because the end cam is subjected to unilateral pressure, the adjustment lever is forced to abut to one side, which causes resistance to its rotation, and it is not clearly known in which state the knitting needle is presently in when the adjustment lever is rotated, and therefore, there is a need for improvement.
