A buckle feeding device for a sewing machine

Abstract

The invention relates to a button feeding device for a sewing machine, which comprises a machine frame, a button feeding slideway and a turn button mechanism, the button delivery slideway includes a pressure plate that can be adjusted up and down, the turn button mechanism includes a friction column, and the turn button mechanism also includes a sleeve , the friction column protrudes from the lower port of the sleeve; the circular cylinder is used to drive the friction column to move downward, including a retractable and tubular output end; the motor, the output shaft of the motor passes through the output end of the cylinder and is connected with the friction The column is connected by a connecting sleeve, which has a certain up and down movement stroke in the sleeve, and also includes a spring elastically resisting the connecting sleeve. The output end of the circular cylinder drives the connecting sleeve to move downward when it moves; the connecting sleeve is in the sleeve. The stroke of the inner upward movement can be adjusted, and it also includes a limit adjustment assembly for adjusting the upward movement stroke of the friction column. The limit adjustment assembly is set in linkage with the upward and downward adjustment of the pressure plate. The height of buckle-feeding slideway and buckle-turning mechanism can be adjusted synchronously.

Description

technical field [0001] The invention relates to a garment processing machine collar, in particular to a button feeding device for a sewing machine. Background technique [0002] With the advancement of technology, the degree of automation in the sewing field is also getting higher and higher. More sewing operations are carried out by automatic operation, such as button sewing. At present, the cooperation of button sewing machines and button feeding machines is generally used. Realize automatic button fastening. [0003] The button feeding machine generally includes a frame and moving parts. There is a button feeding channel on the frame. One end of the button feeding channel is the button-in end, and the other end is the button-out end. In the plate, it is transported from the button-in end to the button-feeding channel through the vibrating plate, and then transported to the button-out end along the button-feeding channel. A button-turning mechanism for rotating the button...

AI Technical Summary

Problems solved by technology

The adjustment of the pressure plate and the friction column needs to be adjusted separately. The two are not adjusted synchronously, and there will be adjustment errors. Multiple adjustments are required, and the adjustment steps are more complicated.
