Zipper assembly device of auto-end-closing injection machine and zipper assembly method of zipper assembly device

Abstract

A zipper assembly device of an auto-end-closing injection machine comprises a main frame of a bench. A guide groove allowing a slider to slide directionally, a pull device driving a zipper to slide along the guide groove, and a zipper assembly mechanism are arranged on the bench. The zipper assembly mechanism comprises a left push arm with a driver, and a right push arm with a driver. The left push arm and the right push arm are disposed on two sides of the guide groove. A slider sensor, a swing bar and a swing bar sensor are further disposed on the bench, wherein the slider sensor senses passage of the slider, the swing bar arranged above the guide groove freely swings up and down around a shaft, and the swing bar sensor senses swinging of the swing bar. The zipper assembly device is capable of assembling zippers different in length, while the position of the zipper assembly mechanism is not adjusted. The zipper assembly device has the function of automatic zipper assembly and is low in labor intensity and high in production efficiency. In addition, the zipper assembly device effectively prevents deformation and scratch of an upper stopper, even breakage of the upper stopper and the like caused by forced assembly of the slider with the zipper, product quality is better guaranteed, and product quality is improved.

Description

technical field [0001] The invention relates to a chain closing device and a chain closing method thereof, in particular to a chain closing device and a chain closing method of an automatic closed injection molding machine. Background technique [0002] The production process of the zipper includes the chain closing process. The previous process of the chain closing process is the assembly of the upper and lower stops. The assembly of the upper and lower stops is mostly injection molding. In the chain closing process, the upper and lower stops discharged from the injection molding machine are relatively soft. During the zipper closing process, it is easy for the slider to forcibly close the chain, causing the top stop to be deformed, scratched, or even broken; It is easy to appear when the slider is pulled over the top stop. The Chinese utility model patent with the patent number "ZL 200620125271.0" discloses a "plastic-steel fully automatic closed-end zipper tooth closing ...
