Description

Technical Field

[0001] The utility model belongs to the technical field of button sewing machines, in particular to a pneumatic button clamp structure of a button sewing machine. Background Art

[0002] A button sewing machine is a type of sewing machine that is specifically used to sew buttons on clothing. When using the button sewing machine, the buttons need to be transported to the button sewing position individually, and the buttons need to be positioned when sewing. The function of the button clamp is to position the buttons at the button sewing position.

[0003] The existing buckle clip includes a clamping part for clamping a button, and the clamping part usually includes two clamping claws, one end of the two clamping claws is hinged to the fixed part of the buckle clip respectively, and the other ends of the two clamping claws are close to each other, so that the button can be clamped, and the button can be released when they are away from each other; the existing buckle clip usually also includes a moving part and a power device, and the middle part of the two clamping claws is provided with a convex structure, and the convex structure on the moving part corresponding to the two clamping claws is provided with two sliding grooves, and the distance between the two sliding grooves gradually decreases from top to bottom, and the convex structure is located in the sliding groove on the corresponding side, and then the moving part is pushed up and down by the power device, and when the moving part moves upward, the two convex structures slide relative to each other. The grooves move downward and approach each other, so that the two ends of the two clamping claws holding the button are close to each other and clamp the button; when the moving part moves downward, the two protruding structures move upward relative to the slide groove and move away from each other, so that the two ends of the two clamping claws holding the button are away from each other and the button is released; currently, most power devices use cylinders or oil cylinders. When the size of the button is large or small, the position of the power device needs to be adjusted so that the button can be clamped. Generally, when adjusting the position of the power device, the power device needs to be disassembled as a whole, and then fixed after the position is adjusted. The position adjustment of the power device is very troublesome. Utility Model Content
