Yarn sequin sewing device of multi-needle sewing machine

Abstract

The invention provides a yarn sequin sewing device of a multi-needle sewing machine, and belongs to the technical field of sewing machines. The device solves the problems of low sewing quality and low production efficiency of the conventional sequin sewing device. The yarn sequin sewing device of the multi-needle sewing machine comprises a needle plate positioned on a workbench plate of a frame, a cutter arranged on a machine needle seat and feeding push rods corresponding to machine needles in quantity; a guide mechanism capable of guiding feeding of sequins is arranged on the needle plate; and a mounting seat is fixedly connected to the end face of the frame, the mounting seat is connected with a push rod fixing rack through a rotating shaft, the feeding push rods are connected to the push rod fixing rack and can swing around the joints, and a driving mechanism capable of driving a push rod fixing seat to swing around the axial line of the rotating shaft through a transmission main shaft so that the feeding push rods push the sequins in the guide mechanism out one by one is also arranged on the mounting seat. According to the sequin sewing device, synchronism of the machine needles and the push rods is high, and the yarn sequin sewing quality is improved.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, and relates to a multi-needle sewing machine, in particular to a yarn sequin sewing device of a multi-needle sewing machine. Background technique [0002] In people's daily life, there are various styles and patterns of clothing. In order to increase the aesthetic effect, many clothing such as underwear, women's fashion, children's clothing, T-shirts, embroidery pattern combinations, handbags, hair accessories, hats, ribbons, lace, etc. need Metal sequins for embellishment. [0003] In the prior art, conventional sewing machines are usually refitted to have the function of sewing sequins in a single row, and some enterprises have designed and developed sewing machines capable of sewing sequins in a single row. For example, the Chinese patent [Application No. 200610085891.O; Publication No. CN1858326A] discloses a sequin guide nozzle mechanism of a sequin embroidery machine, which include...

AI Technical Summary

Problems solved by technology

[0004] Single-row sewing has the problem of low production efficiency. To solve this problem, technicians designed and developed a multi-needle sequin embroidery device, and applied for a Chinese patent [Patent No. ZL200920197757.9; Authorized Notice No. CN201574288U]. The multi-needle sequin embroidery device includes a needle frame, a piece feeding device and a slicing device. The piece feeding device also includes a plurality of ratchets with different numbers of teeth fixed on the output shaft of the motor. The needle frame corresponds to each ratchet. An embroidery needle is installed at the position, and each ratchet is connected with a swing mechanism, and each swing mechanism also includes a ratchet that can cooperate with the teeth of the corresponding ratchet and a connecting rod that is rigidly connected with the ratchet. One end is pivotally connected to a fixed shaft fixed on the motor mounting plate, the other end of the connecting rod is hinged to the shift fork, and a torsion spring that can realize the reset of the swing mechanism is arranged at the hinge of the connecting rod and the shift fork

[0005] The above-mentioned multi-needle-position sequin embroidery device is equipped with multiple ratchet wheels with different numbers of teeth connected to the output shaft of the motor. Since the number of teeth of each ratchet wheel is different, the swing frequency of the corresponding ratchet and shift fork is Different from each other, so as to realize the synchronous embroidery of sequin patterns of different specifications, but the problems of this multi-needle sequin embroidery device are: 1. It adopts the structure of ratchet and pawl, and when the pawl passes through the teeth of the ratchet, 2. The fork that moves the sequins and the cutter that cuts the sequins are driven by a separate motor, and the synchronization with the needle sewing action is difficult to guarantee

The above-mentioned problems may lead to a decrease in the sewing quality of the sequins, greatly reducing the overall visual effect of the garment
