Button clamping mechanism for button sewing machine

Abstract

The invention discloses a button clamping mechanism for a button sewing machine. The button clamping mechanism comprises a ring-shaped bottom ring and a top ring, wherein a rubber ring is clamped between the bottom ring and the top ring, a support is formed on one side wall of the bottom ring, a placing groove is formed in the side wall, facing the bottom ring, of the support, guide grooves extending through the upper face and the lower end face of the support are formed in the inner wall of the upper side and the lower side of the placing groove, a U-shaped adjusting portion is formed in oneend of a rubber ring, the adjusting portion is inserted into the placing groove, a supporting shaft abuts against the adjusting portion in an inserted mode, a pair of supporting lugs are formed in theupper end of the supporting shaft, each supporting lug is hinged to one end of each connecting rod, the other end of each connecting rod is hinged to an adjusting block, the adjusting blocks are located on the two sides of the guiding grooves, inserting grooves perpendicular to the guiding grooves are formed in the support on the two sides of the guiding grooves, the lower ends of the adjusting blocks are inserted into the inserting grooves, an electromagnet layer is arranged on each adjusting block, and the energized electromagnet layers can be adsorbed on the inner walls of the inserting grooves. According to the button clamping mechanism, a rubber ferrule can be adjusted, so that a button can be conveniently clamped.

Description

technical field [0001] The invention relates to the technical field of clothing machinery, in particular to a button clamping mechanism for a button sewing machine. Background technique [0002] A button sewing machine is a machine specially used to sew buttons on clothing and belongs to clothing machinery. When the button sewing machine is in use, the button needs to be transported to the button sewing position separately, and the button needs to be positioned at the button sewing position when the button is nailed, which requires the use of a button clip. At present, button clips are generally held by two fingers, and the buttons need to be accurately positioned when the buttons are transported by the fingers. At the same time, it is necessary to control the force of the button, otherwise the force is too small and the button cannot be clamped. It is easy to cause damage to the button, and the requirements for clamping and positioning the button with the fingers are relat...

AI Technical Summary

Problems solved by technology

At present, button clips are generally held by two fingers, and the buttons need to be accurately positioned when the buttons are transported by the fingers. At the same time, it is necessary to control the force of the button, otherwise the force is too small and the button cannot be clamped. It is easy to cause damage to the button, and the requirements for clamping and positioning the button with the fingers are relatively high, so some people have proposed a clamping structure that uses a rubber ferrule to clamp the button, but the volume of the button is small, and there is no suitable rubber ferrule, so it needs to be adjusted. The clamping structure of the rubber ferrule is improved to realize the clamping button of the rubber ferrule
