Problems solved by technology

The above-mentioned connection methods between the thread hooking rod and the thread hooking fork have not considered the problem of dust accumulation, and after the embroidery machine has been used for a long time, dust will easily accumulate at the connection between the thread hooking rod and the thread hooking fork , so it will increase the linkage resistance between the thread hooking lever and the thread hooking fork, which will affect the normal work of the thread hooking lever and the thread hooking fork, resulting in the inability to hook the thread, affecting the quality of embroidery, and may cause jamming in severe cases, resulting in damage to the machine

Embodiment 1

[0025] like figure 1 and figure 2 As shown, the present invention provides a thread hooking device, which includes a thread hooking driver, a thread hooking lever 1, a thread hooking shift fork 2 and a hooking knife 3. The thread hooking driver drives the thread hooking lever 1 to reciprocate in a straight line. There is a slide block 11, the slide block 11 is provided with a chute 111 perpendicular to the axial direction of the draw bar 1, the slide block 11 reciprocates in a straight line with the draw bar 1, and a ball 21 is arranged on the draw fork 2, and the ball 21 slides Rolling in the groove 111 makes the hooking fork 2 swing back and forth, and the hooking fork 2 drives the hooking knife 3 to reciprocate in a straight line to realize the hooking. There is an air gap 112 between the end extending into the sliding groove 111 and the sliding groove 111 .

[0026] Firstly, use the structure that the chute 111 cooperates with the ball 21 to realize the interlocking mov...

Embodiment 2

[0036] like Figure 7 As shown, the outer diameter of the ball 21 is smaller than the width of the chute 111, two balls 21 can be provided, one of which rolls against a groove wall 1111 of the chute 111, and the other rolls against another groove wall 1112 of the chute 111 Since the two balls 21 move synchronously with the slider 11 in two directions respectively, it can be ensured that the reciprocating movement of the hooking rod 1 can drive the hooking fork 2 to swing in time, so that the hooking knife 3 can be stretched out and retracted. It can be timely and fast, and the hooking efficiency is guaranteed. In order to reduce space occupation and avoid excessive width of the chute 111, the two balls 21 are distributed in a staggered manner in the chute 111, such as Figure 8 shown. It can be understood that the number of balls 21 can be increased as required.

Abstract

The invention discloses a thread hooking device, and belongs to the field of embroidery machine accessories in order to solve a problem that dust accumulation in the prior art reduces the connecting and driving reliability of a thread hooking pull rod and a thread hooking shift fork. The thread hooking device for solving the problem is mainly characterized in that the thread hooking pull rod is provided with a slide block, the slide block is provided with a sliding slot perpendicular to the axial direction of the thread hooking pull rod, the slide block reciprocates linearly with the thread hooking pull rod, the thread hooking shift fork is provided with a ball, the ball rolls in the sliding slot to make the thread hooking shift fork reciprocate and swing, the thread hooking shift fork drives a hook knife to reciprocate linearly in order to realize thread hooking, two ends of the sliding slot penetrate through two opposite sidewalls of the slide block, and a ventilating space is arranged between the end part, extending into the sliding slot, of the ball and the sliding slot. The thread hooking device is mainly used for improving the stability and the reliability of thread hooking of the thread hooking device and prolonging the service life of the thread hooking device.

Description

technical field [0001] The invention relates to embroidery machine accessories, in particular to a thread catcher. Background technique [0002] Embroidery machines use various silk threads to embroider. Due to the contact and wear of the silk threads during the conveying process and the embroidery machine, a lot of dust will naturally be generated. In the existing thread hooker, the thread hook pull rod drives the thread hook shifting fork to rotate through the universal bearing, also drives the thread hook shifting fork to rotate through two pushing sliders and springs, and also uses the swinging connecting rod to drive the thread hooking fork to rotate. Drive the line-hooking fork to rotate. The above-mentioned connection methods between the thread hooking rod and the thread hooking fork have not considered the problem of dust accumulation, and after the embroidery machine has been used for a long time, dust will easily accumulate at the connection between the thread hoo...
