Automatic cloth clamps of embroidery machine

Abstract

The invention discloses automatic cloth clamps of an embroidery machine, wherein each cloth clamp is a set of independent system, and each set of system comprises a control system unit and an actuating mechanism unit. The cloth clamps are controlled by a single chip microcomputer (SCM) to achieve the purposes of automatically disassembling and clamping the cloth clamps of the embroidery machine through actuating mechanisms. The clamps can be disassembled simultaneously or independently according to the requirements of actual production. In the cloth clamping process, the clamps do not need to be pressed and only need to be put on the cloth, and a button is pressed to automatically clamp the cloth. Compared with the prior art, the invention has the advantages that (1) the actuating mechanisms are used for achieving the purpose of clamping cloth, thereby achieving the purpose of replacing manual operation by mechanical operation and achieving the automation of clamping; (2) the SCM is used for controlling the actuating mechanisms to simultaneously disassemble the cloth clamps, so that the cloth clamps of the whole embroidery machine can be disassembled in a very short time, thereby realizing the automation of disassembling, saving the precious time, reducing the production cost and improving the working efficiency. and (3) the automatic cloth clamps are used for replacing manually pressing clamps to clamp cloth, thereby reducing the labor intensity of operators, increasing the average operating number of embroidery machines of the operators, and obtaining very obvious effects on improving the competitive power of products and protecting the working environment of staff. The invention has great application and popularization prospects.

Description

technical field [0001] The invention relates to an automatic cloth clipping and unloading device of an embroidery machine, in particular to the cloth clip in the embroidery machine and its technology. Background technique [0002] The existing embroidery machine cloth clips are all made of spring steel plates to form the shape of the cloth clamping position of the embroidery machine embroidery frame. To achieve the requirement of holding the fabric in the embroidery frame; when the cloth clips need to be removed, the cloth clips should be pulled out of the embroidery frame one by one by hand to loosen the fabric. This is labor-intensive and time-consuming, and the work intensity of the workers is high, and the working environment is just poor. At the same time, because the fabric is fixed by the elastic force of the material itself, when embroidering a pattern with a large number of stitches, due to the large inward pulling force generated, the situation that the cloth clip...

AI Technical Summary

Problems solved by technology

In this way, it is labor-intensive and time-consuming, the work intensity of the workers is high, and the working environment is poor.

At the same time, because the fabric is fixed by the elastic force of the material itself, when embroidering a pattern with a large number of stitches, due to the large inward pulling force generated, the situation that the cloth clip jumps out of the embroidery frame sometimes occurs; The rear flower shape will be displaced, and the produced embroidery will be a waste product

At present, the embroidery industry judges the production capacity of operators as follows: based on the cloth width of 1.4 meters and the pattern of 100,000 stitches per flower, one worker can produce 8 sheets of cloth in 8 hours, that is, clamping the fabric 16 times (because most The height of the embroidery frame is 85CM, so a 1.4-meter piece of cloth needs to be clamped up and down twice,), the length of a piece of cloth is 6 meters, and the head spacing of an embroidery machine is 300CM, and the head of a machine The number is 20, and the length of the cloth clips is equal to the distance between the machine head, that is, the number of cloth clips of a machine: 40 on the two horizontal sides and 6 on the two vertical sides (two of the clips are only 20CM long) Based on this, it is calculated that a cloth worker needs to install and remove the clip 92 times, and the labor intensity can be imagined. Because of this, many workers are unwilling to engage in embroidery operations, resulting in a labor shortage in the industry.
