Single-motor 360-degree all-dimensional shuttle type towel device

Abstract

The invention discloses a single-motor 360-degree all-dimensional shuttle type towel device. The single-motor 360-degree all-dimensional shuttle type towel device comprises a swing needle, a rotatingbase, a driving source, a transmission mechanism and a linkage mechanism, wherein the transmission mechanism is used for transmitting kinetic energy output by the driving source to the swing needle, acavity is formed in the middle of the rotating base, the rotating base can rotate along the center of the cavity, the swing needle comprises a poking end and a driving end, the poking end is locatedin the cavity, the driving end is connected with the transmission mechanism, the transmission mechanism drives the swing needle to move through the driving end, the linkage mechanism comprises a swingpath, a guide part and a limiting part, the limiting part moves in the swing path, and the swing path has a path end point. The linkage mechanism matches with the transmission mechanism, so that thesingle driving source can control the loop poking operation of the swing needle, the purpose of direction adjustment can be further achieved, and the number of required motors and the compression costare effectively reduced.

Description

technical field [0001] The invention relates to a matching device of a computerized embroidery machine, in particular to a 360-degree omni-directional shuttle towel device with a single motor. Background technique [0002] Ring towel stitch is a kind of embroidery pattern on clothing fabrics, which is favored by many female consumers. But existing shuttle type computerized embroidery machine can't produce ring-shaped towel stitches on fabric, and although the common towel embroidery device installed on shuttle type computerized embroidery machine can also produce towel stitches on fabric, but to pattern The direction is required (usually not greater than 180 degrees), and the decorative effect of the embroidered towel stitches is not ideal. [0003] The applicants proposed a utility model patent named "360-degree all-round additional towel embroidery device" on June 1, 2010 (publication number CN101831769A, hereinafter referred to as comparative patent 1); and on December 2...

AI Technical Summary

Problems solved by technology

[0013] 1. The volume occupied by the motor is relatively large, the overall structure is not compact enough, and the operating space for employees is small and the operation is not very convenient

[0014] 2. The motor increases the weight of the embroidery head, increases the power consumption of other components, and leads to an increase in the cost of the embroidery head

Therefore, if the gap is insufficient or filled with wool dust, it is easy to cause jamming between the shift fork 4 and the shift fork sleeve 24, so that the coil picked out by the pendulum needle 19 is different from the preset shape

[0016] 4. Since the pendulum needles in the comparison patent 1 and the comparison patent 2 all perform reciprocating arc swings along their pivots, the shape of the lifted coil is "U" in the vertical plane, and the flatness of the coil is relatively high. Low
