Overlock sewing machine for cloth waste

Abstract

The invention relates to the technical field of sewing machines, in particular to an overlock sewing machine for cloth waste. The overlock sewing machine for the cloth waste comprises a machine table,a rack, a needle head and a controller. The rack is installed on the machine table, the needle head is installed on the rack, and the controller is installed on the rack; the machine table comprisesa first motor and a slide plate, and the machine table is provided with a slide rail; the slide plate comprises a downward pushing plate and conical springs, groove ports are formed in the slide plate, the downward pushing plate is installed at the bottoms of the groove ports, and the conical springs are arranged over the downward pushing plate; a fixing module comprises a second motor, a lead screw, a slide block, a first air cylinder and an upward pressing plate; the rack is provided with a slide groove; the upward pressing plate is connected to the end of the first air cylinder, and the upward pressing plate and the downward pushing plate can be matched with each other for clamping cloth. According to the overlock sewing machine, automatic clamping and fixing can be achieved during cloth sewing, the instability caused when the cloth waste is fixed by hand is effectively overcome, so that cloth sewing is always conducted on the same straight line, and the sewing effect is better.

Description

technical field

[0001] The invention relates to the technical field of sewing machines, in particular to a rag sewing machine. Background technique

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew fabrics such as cotton, fiber crops, silk, wool, and artificial fibers, and products such as leather, plastics, and paper.
