Cloth overlock cutting and sewing machine

Abstract

The cloth overlock cutting and sewing machine according to the present invention includes an installation structure, and the installation structure is sequentially provided with a feeding unit, a cutting unit, a sewing unit, a positioning unit, a rotating folding unit, a cutting unit, and a cloth sewing unit; The unit includes a clamping mechanism for clamping the cloth, a rotating mechanism connected with the clamping mechanism and whose rotation axis is perpendicular to the feeding direction, and a movable mechanism connected with the rotating mechanism; the clamping mechanism clamps the cloth and passes through the movable mechanism to make the cloth Folding provides space, and the rotating mechanism drives the clamping mechanism to turn over to change the folding direction of the fabric. The position changes of the above-mentioned components realize the folding of long fabrics. The position change of the movable mechanism of the present invention realizes one round of folding of the long cloth. During the folding process, the rotating mechanism is turned, and the length of the folded cloth is determined by the space determined by the movable mechanism, so that the device is suitable for folding long cloth.

Description

technical field [0001] The present invention relates to the technical field of fabric sewing devices, and more particularly, to a fabric overlock cutting and sewing machine. Background technique [0002] A mattress is an item between the human body and the bed board used to ensure a healthy and comfortable sleep for consumers. The side of the mattress is usually sewn with a perimeter strip, also called a perimeter, the width of which is basically the same as the thickness of the mattress, and surrounds the mattress along the perimeter of the mattress. [0003] The common processing methods of mattress side strips on the market are: first use a machine to lock the material, and then manually measure the position of the handle that needs to be sewn and the position of the brand air hole, and then manually measure the required length and cut it. Then the handle is stitched, and finally the stitching is done. The disadvantages of such a process are: there are many processing s...

AI Technical Summary

Problems solved by technology

The disadvantages of this kind of process are: many processing steps, the length and size of manual measurement are not standard, and the efficiency is low; the number of machines is large, the area is large, and the cost is high; the processing steps are complicated and the technical requirements are high, and 5 people are needed to complete the enclosure processing

However, due to the limitation of the vertical swing range of the rotating shaft, this technical solution has little space for stacking fabrics, and is not suitable for folding fabrics with a long length.
