Description

Technical Field

[0001] The invention relates to the technical field of zipper manufacturing equipment, in particular to a continuous zipper tape turning, cutting and side-out unit and a zipper manufacturing equipment with the unit. Background Art

[0002] The manufacture of a zipper requires many processes, including gluing, punching, sizing, forming a bottom stop, forming a square latch, cutting, threading, forming an upper stop, and discharging. In the processes of gluing, punching, sizing, forming a bottom stop, and forming a square latch, the external form of the semi-finished zipper to be processed is a continuous zipper tape, with the lower end stop as the head, moving forward, passing through the gluing device for gluing, passing through the punching device for punching, passing through the sizing device for sizing, passing through the bottom stop forming device for forming a bottom stop or passing through the square latch forming device for forming a square latch, and then the continuous zipper tape is cut between the previous upper end stop and the next lower end stop by the cutting device, thereby becoming a separate semi-finished zipper that is no longer continuous. The separate semi-finished zipper must then be taken as the head of the upper end stop, move forward, pass through the threading device to put on the slider, pass through the upper stop forming device to form the upper stop, and then be discharged by the discharging device, thus completing the manufacture of a zipper.

[0003] With the increasing demand for automation in zipper manufacturing, various zipper manufacturing automation equipment is increasingly being widely used in the zipper manufacturing field, and even fully automated equipment for zipper gluing, punching, sizing, forming bottom stops or forming square plugs, and fully automated equipment for zipper cutting, threading, forming top stops, and discharging have appeared. However, in the processes of zipper gluing, punching, sizing, forming bottom stops or forming square plugs, the lower end stop is the head and moves forward, while in the processes of zipper threading and forming top stops, the upper end stop is the head and moves forward. As a result, for a long time, the connection between the processes of zipper gluing, punching, sizing, forming bottom stops or forming square plugs and the processes of zipper threading and forming top stops has been done manually to turn the zipper around. Therefore, it is very regrettable that there has been no automatic zipper cutting, threading, forming, and discharging of zippers that can connect the processes of zipper gluing, punching, sizing, forming bottom stops or forming square plugs with the processes of zipper threading and forming top stops. There is no automated unit that can automatically connect the processes of forming the bottom stop or forming the square pin with the processes of zipper threading and forming the top stop and realize U-turn. There is also no zipper manufacturing pre-process equipment that can automatically connect with the processes of zipper threading and forming the top stop, or a zipper manufacturing post-process equipment that can automatically connect with the processes of zipper gluing, punching, sizing, forming the bottom stop or forming the square pin, and there is no fully automated equipment for the pre- and post-processes of zipper manufacturing. It is increasingly unable to meet people's demand for full automation of zipper manufacturing equipment. Summary of the invention
