A zipper assembly machine

Abstract

A zipper puller assembling machine comprises a machine frame, vibrating disc feeding mechanisms and a rotating table. The rotating table comprises a rotating disc and a rotating table base, a plurality of station grooves are formed in the rotating disc, clamping blocks capable of containing zipper pullers are installed in the station grooves, and positioning grooves matched with zipper pullers in shape are formed in the front portions of the clamping blocks. A stamping head is arranged above the rotating disc. The zipper puller assembling machine further comprises a returning mechanism. The returning mechanism comprises a returning stop block and a blowing pipe. Pushing assemblies are arranged in the clamping blocks and used for applying pushing force to zipper pullers to promote returning. Each pushing assembly comprises an ejecting rod, a beating cap, a connecting rod and a pushing plate, wherein the ejecting rod is used for pushing zipper pullers to move outwards, and the beating cap, the connecting rod and the pushing plate are used for driving the ejecting rod to move transversely, and the beating cap and the ejecting rod are sleeved with springs respectively. Positioning parts are arranged on the rear portions of the clamping blocks in an upward protruding mode, the beating caps protrude out of the upper end faces of the positioning parts, and through holes for the ejecting rods to penetrate through are formed in the end faces of the positioning grooves. The returning mechanism further comprises a beating air cylinder used for striking the beating caps. The zipper puller assembling machine is stable in returning and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an assembly machine, in particular to a zipper slider assembly machine. Background technique [0002] The zipper slider, as an important part of the zipper, is mainly composed of a pull piece, a slider body, a hook and a cap. The cost is too expensive for enterprises to bear. Nowadays, mechanized production equipment has appeared, which can replace manual assembly of zipper pullers to a certain extent, reducing production costs. [0003] Existing zipper slider assembly equipment generally includes basic structures such as a vibrating disc feeder for feeding, a turntable with a processing station and a gas blowing pipe for returning materials. The slider body is positioned on the processing station and rotates with the turntable. In order to prevent the zipper slider from leaving the processing station during assembly, the clamp on the processing station exerts a certain clamping...

AI Technical Summary

Problems solved by technology

The slider body is positioned on the processing station and rotates with the turntable. In order to prevent the zipper slider from leaving the processing station during assembly, the clamp on the processing station exerts a certain clamping force on the slider body, and the gas The ejection method of the blowing tube is unstable, and the zipper head cannot be blown out of the processing station effectively and quickly, and when the zipper head is subjected to a relatively large clamping force, the strength of the gas blowing pipe is insufficient, which affects the assembly progress

[0004] Secondly, there will be more scraps and impurities on the processing table, some of which are burrs and scraps dropped by the zipper head itself, and some are impurities carried by automatic feeding. These scraps and impurities are easy to fall into the turntable, making the turntable It is stuck and cannot be rotated, and it is not easy to clean and maintain
