Problems solved by technology

[0003] The sewing machine used now has gradually changed from the previous manual to automatic, and the cloth can also be automatically supplied by some machinery. When the sewing machine is working, the supply or grabbing of the cloth is mostly completed by a cloth suction device with a suction cup-shaped suction head. The suction device uses vacuum force to absorb the cloth and move it to the predetermined position, but there are still some shortcomings in the use of this device: (1) The applicable cloth range is small, and it can only be used for the cloth with very dense yarn fibers. , and most of the fabrics are knitted or woven, the gaps between the yarn fibers of these fabrics are relatively large, and there will be air leakage during the actual suction device, causing the fabric to not be absorbed; (2) due to the yarn of the fabric There is a gap between the fibers, the cloth and the sucti

Abstract

The invention provides a cloth gripping device which comprises a gripping arm body. One end of the gripping arm body is provided with a cavity. One end of the cavity is covered with an elastic film piece arranged on the gripping arm body. The elastic film piece is provided with a through hole. The other end of the cavity is connected with an air pipe. The outer side of the elastic film piece is provided with a plurality of rows of needle-shaped protrusions. According to the cloth gripping device, by means of the adsorption force of air pressure and the clamping force of the needle-shaped protrusions, automatic feeding of cloth is stable and reliable. Moreover, due to the clamping function of the needle-shaped protrusions, the applicable cloth range of the cloth gripping device is wide. In addition, due to the special structure, the energy consumption in the working process of the cloth gripping device is small and the noise is low.

Description

technical field [0001] The invention relates to an auxiliary device of a sewing machine, in particular to a cloth grabbing device. Background technique [0002] With the development of the sewing machine industry, more and more sewing machines are used in different fields of production and life, and the auxiliary equipment matched with the sewing machine is gradually enriched. [0003] The sewing machine used now has gradually changed from the previous manual to automatic, and the cloth can also be automatically supplied by some machinery. When the sewing machine is working, the supply or grabbing of the cloth is mostly completed by a cloth suction device with a suction cup-shaped suction head. The suction device uses vacuum force to absorb the cloth and move it to the predetermined position, but there are still some shortcomings in the use of this device: (1) The applicable cloth range is small, and it can only be used for the cloth with very dense yarn fibers. , and most ...
