Pin selecting piece group of pin selector

Abstract

The invention relates to a pin selecting piece group of a pin selector. The pin selecting piece group comprises a plurality of pin selecting pieces which are connected onto a shell of the pin selectorin a swinging manner and correspond to striking pins projecting out of a pattern bit, axis of oscillation of the plurality of pin selecting pieces are parallel to one another and stay on a same plane, each pin selecting piece is provided with a tool bit extending out of the pin selector shell, the tool bit is provided with an oblique surface, and the oblique surface can contact the striking pinscorresponding to the tool bit on the pattern bit in a sliding manner. The oblique surface forms an acute angle alpha with the length direction of the pin selecting piece, and the angle alpha corresponding to the oblique surface of the pin selecting piece is gradually increased according to a sequence from top to bottom. The oblique surface on the tool bit of the pin selecting piece has different oblique angles according to different positions, so that a friction contact distance between the original tool bit and the pattern bit is shortened, the friction force between the original tool bit andthe pattern bit is also reduced, the problem in the prior art that the striking pin is severely abraded on the pattern bit is solved, and the service life of the pattern bit is prolonged.

Description

technical field [0001] The invention relates to a needle selector group of a needle selector, which is applied to a jacquard circular machine. Background technique [0002] Jacquard circular knitting machine is more and more widely used because of its ability to weave richer patterns. The needle selector is an important part of the circular jacquard machine. During the weaving process, its action is controlled by the control system according to the fabric pattern design, thereby driving the movement of the jacquard piece on the circular jacquard machine, so that the thread change mechanism can perform thread change knitting at an appropriate time. . as attached figure 1 And attached figure 2 As shown, in the prior art, the jacquard piece revolves around the central axis of the jacquard circular machine, the central axis is parallel to the length direction of the jacquard piece 50, and the needle selector 10 is formed by the loop joint 40 (see the appendix for the coil jo...

AI Technical Summary

Problems solved by technology

Since the jacquard sheet swings with its own lower end as the fulcrum, and its striker pins are arranged in the up and down direction, the stroke length of the frictional contact between the striker and the cutter head is different, resulting in more serious wear of the striker with a long frictional contact stroke with the cutter head, which seriously affects the Service life of jacquard sheets
