Cloth feeding adjustment system for sewing machine

Abstract

The invention discloses a cloth feeding adjustment system for a sewing machine, the structure of which comprises a synchronous belt, a main shaft, a machine body, a guard plate, a workbench, a deviation correcting device, a winding device, a cloth feeding tooth, a transmission shaft, and a cloth feeding dog frame. When the invention is improved and used, the neat cloth is fixed on the convex clamping block through the rubber pad, the push rod is pushed, the buckle block slides into the inside of the connecting buckle, and the spring drives the arc-shaped buckle to pop out to the outside, so that the arc-shaped buckle can be It is fixed and fastened with the connecting buckle, and the fabric can be sewed according to the required running path, which improves the sewing work efficiency; the sewn fabric is transported to the movable roller through the winding rotating disc, and the sliding guide plate and the moving slow plate cooperate with each other The auxiliary movable roller conveys the cloth, and the rotating roller conveys the cloth to the other end of the chute, and the cloth is rewound at a uniform speed through the movable roller and the sliding guide plate at the other end, which can realize that the cloth is not easy to wrinkle during output and ensure sewing The quality of the finished fabric.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a cloth feeding adjustment system for a sewing machine. Background technique [0002] With the evolution and development of sewing machine technology, more and more functions of sewing machines have been refined, and clothing, shoes and hats, etc. need to be processed with sewing machines. A sewing machine uses one or more sewing threads to stitch a layer or A machine for interweaving or sewing multiple layers of sewing materials, including a needle bar mechanism, a thread take-up mechanism, a feeding mechanism, a thread hooking mechanism, a pressing mechanism, a thread clamping device and a lubricating device, etc. When sewing and feeding the sewing material, the areas that need to be improved: [0003] 1. When feeding and sewing sewing materials, it is necessary for the operator to hold the edges of the fabric at both ends with both hands, align and overlap the edges of the fa...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a cloth feeding adjustment system for sewing machines, so as to solve the problem that when the sewing materials are fed and sewed, it is necessary for the operator to hold the edges of the cloth at both ends with both hands, and the cloth is The edges are aligned and superimposed, and then the running path of the selvedge is controlled by the hands, the fabric is fixed and positioned at the operating position, and the sewing is carried out through the machine head. Since the unsewn part of the sewing material has a large area, the worker is sewing It is very inconvenient to operate at the hem, which reduces the sewing work efficiency; when feeding the sewn fabric, there will be friction between the presser foot and the fabric that hinders the movement of the fabric, and the friction has the opposite effect on the movement of the fabric. When sewing and winding relatively smooth and thin fabrics, the control of the fabrics is unstable, causing wrinkles or tearing of the fabrics, resulting in a decrease in sewing quality or defective products, increasing production costs and reducing sewing results. question
