Abstract

The invention discloses a material folding mechanism of a bottom crotch attaching sewing machine. The material folding mechanism comprises a supporting plate used for placing a bottom crotch sheet, the supporting plate is provided with a supporting face used for supporting a bottom plate sheet, and a first limiting plate and a second limiting plate which are higher than the supporting face are arranged at the two sides of the supporting plate. Material folding plates used for folding the two ends of the bottom crotch sheet are arranged at the two ends of the supporting plate respectively. According to the material folding mechanism, the first limiting plate and the second limiting plate which are higher than the supporting face are arranged at the two sides of the supporting plate, the situation that the bottom crotch sheet is distorted and misaligned when placed on the supporting face is prevented, and the folding quality of the bottom crotch sheet is improved.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a bottom rail sewing machine for automatic feeding, folding, cutting and laminating sewing of bottom rails. Background technique [0002] In the processing technology of trousers, there is a process of attaching the bottom shelf. At present, the bottom shelf is mainly folded manually, and then aligned and placed at the bottom shelf, and the sewing machine is used for sewing. The existing technology requires high proficiency of workers, high labor cost, and low processing efficiency. Contents of the invention [0003] Aiming at the technical problems of easy distortion and difficult alignment during the automatic folding process of the bottom rail, the present invention provides a material folding mechanism for the bottom rail sewing machine, which can ensure the accuracy of folding the bottom rail and prevent the material from being twisted or twisted during folding. misalignment etc. [0...
