Double-thread sewing machine capable of preventing hand pinching

Abstract

The invention discloses a double-thread sewing machine capable of preventing hand pinching. The double-thread sewing machine comprises a supporting plate and a double-thread sewing machine body, the double-thread sewing machine body is arranged on the top surface of the supporting plate, the two sides of the output end of the double-thread sewing machine body are provided with rubber sleeves, first springs are arranged in the rubber sleeves, and two first fixing frames are fixed at the bottom of the supporting plate; second springs are fixed to the top surfaces of the interiors of first grooves, and a motor is installed on the top surface of a first mounting plate; the end of an output shaft of the motor is rotationally connected with a second roller through a coupler, and a second mounting plate is fixed to the outer wall of the supporting plate; a second fixing frame is fixed to the top surface of the second mounting plate, and the bottom of a third spring is located in a second groove and is rotationally connected with a third roller through a second connecting pin. The double-thread sewing machine can well prevent hands from being pinched during work, meanwhile, long cloth canbe conveniently sewn, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of double-thread sewing machines, in particular to a hand-clamping-proof double-thread sewing machine. Background technique [0002] Double-needle sewing machine (also called double-needle flat car) is a commonly used sewing machine with two needles, two synchronizations, three synchronizations, and the corner sewing effect is that the double threads are juxtaposed and parallel to each other. But it is indispensable. Although the flat car can sometimes replace the double needle, considering the efficiency, use the flat car to do the work of the double needle in mass production. Unless it is a small amount of production, the double needle is efficient and the double lines are parallel and neat. Double-needle sewing machine is a commonly used sewing machine with two needles, two synchronous, three synchronous, and turning corners. The sewing effect is that the double threads are side by side and parallel to ea...

Problems solved by technology

[0004] The object of the present invention is to provide a double-thread sewing machine that prevents hands from being pinched, which is used to solve the problem that the double-thread sewing machine mentioned in the background technology does not have a protective function when it is working, and it is easy to pinch your hands if you are not careful when using it. At the same time, the double-thread sewing machine All materials are fed by hand, which is not convenient for sewing long fabrics, and the efficiency is relatively slow.
