Description

Technical Field

[0001] The utility model relates to the technical field of automobile safety airbags, in particular to a cloth sewing device for automobile safety airbags. Background Art

[0002] The automobile airbag system is a passive safety protection system (see automobile safety performance). It works in conjunction with seat belts to provide effective collision protection for passengers. In the event of a car collision, the airbag can reduce the rate of head injuries by 25% and the rate of facial injuries by about 80%.

The airbag fabric pressing mechanism comprises a transverse pressure rod slidably disposed between the two support frames and a pressing cylinder connected to the transverse pressure rod. The control system controls the pressing cylinder to drive the transverse pressure rod up and down along the two support frames to press the airbag fabric to be sewn. The control system controls the sliding sewing mechanism to move relative horizontally, thereby sewing the airbag fabric. This utility model achieves the rapid docking of two rolls of fabric and the continuous production of airbag fabric on the equipment, improving production efficiency and reducing worker labor.
