Continuous fastener tape turning-around and cutting-off unit and zipper manufacturing equipment adopting continuous fastener tape turning-around and cutting-off unit

Abstract

The invention discloses a continuous zipper tape turning-around and cutting-off unit which comprises a tape pulling device used for pulling a continuous zipper tape to advance, a positioning device used for positioning a lower end stop part of the zipper and a cutting-off device used for cutting off the continuous zipper tape between an upper end stop part and a lower end stop part; the unit further comprises a tape guiding device is used for guiding the continuous zipper tape to turn around and advance, and a conveying device used for conveying the zipper which turns around and is cut off. The positioning device, the cutting-off device, the conveying device and the zipper tape pulling device are sequentially arranged in the turning advancing direction of the continuous zipper tape. Through the design and application of the continuous zipper tape turning-around and cutting-off unit, the automation degree of the zipper manufacturing equipment is greatly improved, and the requirement ofpeople for zipper manufacturing automation at present can be met.

Description

technical field [0001] The invention relates to the technical field of zipper manufacturing equipment, in particular to a continuous zipper tape turning and cutting unit and zipper manufacturing equipment using the unit. Background technique [0002] Manufacturing a zipper needs to go through many processes, including gluing, punching, dimensioning, forming the bottom stop, forming a square pin, cutting, threading, forming the top stop, and discharging. In the processes of gluing, punching, sizing, forming bottom stop, and forming square pins, the external form of the semi-finished zipper as the processing object is a continuous zipper tape, with the bottom end as the head, moving forward, passing through The gluing device is used to apply glue, the punching device is used to punch holes, the dimensioning device is used to determine the size, the bottom stop forming device is used to form the bottom stop or the box pin forming device is used to form the box pin, and then the...

AI Technical Summary

Problems solved by technology

However, in the processes of zipper pasting, punching, dimensioning, forming the bottom stop or forming the box plug, the bottom end is used as the head to move forward, while in the processes of zipper threading, forming the top stop, etc., it is the upper end. For a long time, the connection between the processes of zipper glueing, punching, dimensioning, forming bottom stop or forming square pin and zipper threading, forming top stop and other processes has been done manually. The U-turn of the zipper is done manually, so it is a pity that there is no automatic connection between the processes of zipper glueing, punching, dimensioning, forming bottom stop or forming square pin with the processes of zipper threading and forming top stop. There is no automatic U-turn unit, and there is no zipper manufacturing pre-production equipment that can be automatically connected with zipper threading, forming top stop, etc., or can be connected with zipper glue, punching, dimensioning, forming bottom stop or forming square pins A kind of post-zipper manufacturing equipment that automatically connects, and there is no fully automated equipment before and after zipper manufacturing, which is increasingly unable to meet people's needs for fully automated zipper manufacturing equipment.
