Auxiliary device for sewing double-layer clothes for sewing machine

Abstract

The invention relates to the technical field of cloth sewing devices, and discloses an auxiliary device for sewing double-layer clothes for a sewing machine. The auxiliary device comprises a main fixing frame, an operation table is arranged in the main fixing frame, a device box is arranged at the right side of the operation table, and a first rotating wheel, a second rotating wheel and a third rotating wheel are sequentially arranged in the device box from bottom to top. A lower conveying roller is fixedly connected to the first rotating wheel, an upper conveying roller is fixedly connected to the third rotating wheel, and a driving motor is arranged in front of the device box. The driving motor drives a lower conveying roller to rotate clockwise to convey cloth, the lower conveying roller drives the third rotating wheel to rotate clockwise through the second rotating wheel, the rotating speed of the first rotating wheel is the same as that of the third rotating wheel, therefore the upper conveying roller and the lower conveying roller rotate at the same speed to convey cloth, the transmission speed is same, when the two kinds of cloth are sewn, the phenomenon of cloth staggeringis avoided, cloth waste caused by cloth staggering is avoided, and the utilization rate of the cloth is increased.

Description

technical field [0001] The invention relates to the technical field of cloth sewing, in particular to an auxiliary device for sewing double-layer clothes with a sewing machine. Background technique [0002] At present, the sewing machine is the most commonly used machine for sewing clothes and fabrics. When the sewing machine is sewing the fabric, the movement of the fabric is generally completed by people. There are some problems in this way of moving the fabric. When sewing double-layer fabrics, artificial Moving the cloth can not ensure that the moving speed of the two layers of cloth is the same, so that the clothing has the disadvantage of misalignment during sewing. The misplaced clothing will cause the deviation of sewing, and the clothing cannot meet the use requirements, which will cause waste of cloth. In order to solve the above problems, An auxiliary device for sewing double-layer clothes with a sewing machine is now proposed Contents of the invention [0003]...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the invention provides an auxiliary device for sewing double-layered clothes with a sewing machine, which has the advantages of making the conveying speed of the double-layered cloths the same, avoiding the dislocation of the cloths, and rolling the cloths, and solving the problem of artificially moving the cloths. Can't ensure that the two layers of fabric move at the same speed, resulting in misalignment of the garment when sewing
