Cloth fixing device during shutdown of sewing machine

Abstract

The invention relates to the technical field of sewing machine machinery, and discloses a cloth fixing device during the shutdown of a sewing machine, the device includes a center shaft, a spring is connected with the right side of the center shaft movably, a moving rod is fixedly connected with the end, far away from the center shaft, of the spring, according to the cloth fixing device during theshutdown of the sewing machine, through the connection of a base and the center shaft, the connection of the base and a moving bar, a stop board connected with the moving bar can stop the offset of cloth when a whole clamp device opens and does not clamp the cloth; through the connection of an expansion rod and a special-shaped air pipe, air pressure generated by the up-down movement of the sewing machine can enters the bottom end of a cylinder through the special-shaped air pipe, a piston at the bottom can be pushed to move, the piston extrudes the spring to the left end to move leftward through the moving rod connected with the center shaft, the distance of two clamp buckles is lengthened, when the air pressure is reduced, the piston moves rightward, the spring moves leftward, the center shaft drives the moving rod to move rightward, and the distance of the clamp buckles is shortened to clamp the cloth.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a device for fixing cloth when a sewing machine is shut down. Background technique [0002] After the industrial revolution in the middle of the 18th century, the large-scale production of the textile industry promoted the invention and development of sewing machines. After the Second World War, the sewing machine industries in the former West Germany, Italy and Japan developed rapidly, and European countries still produced high-end traditional household sewing machines. Outside the company, most companies started producing industrial sewing machines. In the early 1990s, it began to transfer to China in an all-round way. According to the driving mode, it can be divided into hand, pedal, and electric sewing machines. [0003] Due to the development of e-commerce, a large number of clothing products are sold, and electric sewing machines are widely used. Most of the sewi...
