The front code clamping mechanism of the zipper assembly machine

Abstract

The invention provides a top stop clamping mechanism of a zipper assembling machine. A clamping bar is partitioned into a front portion and a back portion at the hinge point of a slider container. The top stop clamping mechanism comprises a driving medium with a transmission spring driver, and a sensor, wherein the sensor is connected with a transmission device, which moves forwards and backwards in a reciprocating way on a base, of a transmission slider container; when the slider container moves to the foremost end, a transmission spring is used for driving the driving medium to supply torque for driving the back portion of the clamping bar to move towards the outer side, and the torque is greater than torque applied to the clamping bar by a distance reset spring at the moment; when the slider container moves to the rearmost end, torque applied to the clamping bar by the driving medium is smaller than torque applied to the clamping bar by the distance reset spring at the moment, and the sensor is used for receiving a position signal of the driving medium. When a top stop is not placed onto the clamping bar normally, torque applied to the clamping bar by the driving medium overcomes the distance reset device to reduce the distance between the front ends of left and right front clamping bars, the position of the driving medium is in an abnormal workings state, a signal received by the sensor is an abnormal working state signal, the transmission device stops working, manual processing is performed, and work is continued after processing.

Description

technical field [0001] The invention relates to a front code clamping mechanism of a zipper assembly machine. Background technique [0002] Zipper (zipper) The zipper is a connecting piece that relies on the chain teeth arranged continuously to make the items merge or separate. It is now widely used in clothing, bags, tents, etc. The zipper is composed of a zipper body, chain teeth, slider, upper and lower stops (front and rear) or locking pieces. The top stop (topstop or front code) is fixed on the belt body of the zipper, and the stopper that prevents the slider from sliding out of the belt body when the zipper is closed; currently, the top stop of the zipper is set on the belt body through the clamping mechanism when the zipper is assembled , the assembly process includes putting the front stopper into the clamping mechanism, and the clamping mechanism fixes the front stopper on the belt of the zipper, so it often happens that the front stopper is not normally placed in ...

Problems solved by technology

The top stop (topstop or front code) is fixed on the belt body of the zipper, and the stopper that prevents the slider from sliding out of the belt body when the zipper is closed; currently, the top stop of the zipper is set on the belt body through the clamping mechanism when the zipper is assembled , the assembly process includes putting the front stopper into the clamping mechanism, and the clamping mechanism fixes the front stopper on the belt of the zipper, so it often happens that the front stopper is not normally placed in the clipping mechanism, or the front stopper is stuck Into the device, and the clamping mechanism works in a normal state, resulting in no fixed upper front code on the belt body, and because of the fast production speed of the assembly machine, a large number of unqualified products without upper front code will be produced, which need to be selected and carried out. Reloading the clamping code will affect the production
