Automatic cloth laying machine and automatic cloth finishing device thereof

Abstract

An automatic cloth finishing device is arranged on a knife rest of an automatic cloth laying machine. The automatic cloth finishing device comprises a drive piece, drive connecting arms, a rotary shaft, first swing arms, second swing arms and a cloth finishing piece. One end of the rotary shaft is fixedly sleeved with one ends of the drive connecting arms. The rotary shaft is supported on the knife rest through multiple supporting seats arranged on the knife rest. The rotary shaft is rotationally connected with a supporting frame. One end of each first swing arm is fixedly connected to the rotary shaft. The other end of each first swing arm is movably connected with one end of the corresponding second swing arm. The second swing arms can rotate around the connecting points of the first swing arms and the second swing arms. The other ends of the second swing arms are connected with the cloth finishing piece. Drive pieces drive the drive connecting arms to rotate. The drive pieces drive the cloth finishing piece to be switched between the cloth finishing position and the collection position in a reciprocating manner through linkage of the drive connecting arms, the rotary shaft, the first swing arms and the second swing arms. The invention further discloses an automatic cloth laying machine with the automatic cloth finishing device.

Description

technical field [0001] The present invention relates to the technical field of automatic cloth spreading in garment machinery, and more precisely relates to an automatic cloth spreading machine and an automatic cloth unscrambling device thereof. Background technique [0002] With the development of science and technology and the popularization of industrial automation, automatic cloth spreading machines have been widely used in garment production. The high production efficiency, convenient operation mode and economical production cost make automatic cloth spreading machines more and more popular among customers. . However, during the spreading process of the existing automatic spreader, because the pulling device of the spreader generates traction in the length direction of the spread during the process of pulling the fabric, when the traction speed is greater than the feeding speed, it will produce Wrinkles in the length direction of the cloth, after multi-layer cloth spre...

AI Technical Summary

Problems solved by technology

However, during the spreading process of the existing automatic spreader, because the pulling device of the spreader generates traction in the length direction of the spread during the process of pulling the fabric, when the traction speed is greater than the feeding speed, it will produce Wrinkles in the length direction of the cloth, after multi-layer cloth spreading, the edges of each layer of cloth will appear uneven, not straight, and wrinkled, especially when the cloth width is too wide and the cloth is too long, this defect phenomenon is more prominent ; and when the traction speed is lower than the feeding speed, the laid fabric will produce wrinkles along the width direction of the spread

Irregular edges mean that the effective area of ​​the cloth is reduced. Wrinkles will not only affect the neatness of the opposite sides, but also affect the size deviation of the automatic cutting of the cloth in the next process.

This will affect the quality of automatic spreading of the spreading machine, resulting in waste of fabrics, and even some fabrics cannot be used after cutting and scrapped

At present, the problem of wrinkles along the width and length of the spreading process is solved by manually adjusting the leveling. However, the manual finishing is inefficient and highly dependent on people. At the same time, manual There are also certain safety hazards in the finishing process
