Cloth overlock cut-off and sewing machine

Abstract

The invention discloses a cloth overlock cut-off and sewing machine that comprises a mounting structure, wherein a discharging unit, a cutting unit, a sewing unit, a positioning unit, a rotary foldingunit, a cut-off unit and a cloth sewing unit are sequentially arranged on the mounting structure; the rotary folding unit comprises a clamping mechanism used for clamping cloth, a rotating mechanismconnected with the clamping mechanism, and a movable mechanism connected with the rotating mechanism, and the rotating axis of the rotating mechanism is perpendicular to a feeding direction; the clamping mechanism clamps the cloth to provide space for cloth folding through the movable mechanism; the rotating mechanism drives the clamping mechanism to turn over to change a cloth folding direction;and long cloth folding is achieved through position change of the above-mentioned components. One-round of folding of the long cloth is achieved through position change of the movable mechanism, steering is conducted through the rotating mechanism in a folding process, the length of the folded cloth is determined by the space determined by the movable mechanism, and therefore the device is suitable for folding of the long cloth.

Description

technical field [0001] The invention relates to the technical field of cloth sewing devices, and more particularly, to a cloth overlock cutting and sewing machine. Background technique [0002] A mattress is an article between the human body and the bed board used to ensure consumers get a healthy and comfortable sleep. The side of the mattress is usually sewn with a surrounding strip, also called a surrounding edge, whose width is basically the same as the thickness of the mattress, and surrounds the mattress along the perimeter of the mattress. [0003] The common processing method of the mattress side panel on the market is: firstly use the machine to lock the edge of the material, and then manually measure the position of the handle to be stitched and the position of the trademark air hole, and then manually measure the required length and cut it off. Hand stitching is then performed, followed by splicing. The disadvantages of this kind of process are: many processing ...

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.
