The fixing block 416 is detachably fixed, so that when the chain belt needs to be replaced, the fixing block 416 can be removed, the rear end of the upper plate can be pressed down, the front end of the upper plate can be lifted up, and the pin split chain sliding groove 44 is opened to facilitate the replacement of the chain belt.

[0058] The latch sub-chain sliding groove 44 includes a chain tooth sliding groove 441 and a chain belt sliding groove 442, and the chain tooth sliding groove 441 is half arranged on the upper plate 411 and half arranged on the lower plate 412. Since the chain tooth 108 of the chain belt protrudes upward and downward, the above arrangement makes the shape of the latch sub-chain sliding groove 44 and the chain belt more matched, so that the sliding groove drives the chain belt to move and position more accurately.

[0059] The upper and lower air cylinders 42 are fixed on the support, the driving end of the upper and lower air cylinders 42 is fixed with a first connecting seat 421, the left and right air cylinders 43 are fixedly connected with the first connecting seat 421, the driving end of the left and right air cylinders 43 is connected with a second connecting seat 431, the second connecting seat 431 is fixedly connected with a wire rail 432, the wire rail 432 is fixedly connected with the lower plate 412 of the latch sub-chain moving plate 41, and the first connecting seat 421 is further provided with a sliding seat 433 matched with the wire rail.

The pull head fixing groove 34 first fixes the position of the pull head 109, then the chain belt traction device 1 drives the chain belt 10 to move, so that the block 103 moves into the block fixing groove 33, the sensing ejector pin 36 on the block fixing groove 33 can sense the block 103 to be in place, then the positioning cylinder 36 is controlled to drive the positioning block 37 to extend and press the block 103, so that the effect of positioning and stabilizing the position of the block 103 is achieved, and the chain is conveniently completed.

[0061] The latch sub-chain 102 of the block positioning device 4 is further provided with a latch safety device 6, the latch safety device 6 includes a mechanical clamp 61, an opening and closing cylinder 62 and a horizontal moving cylinder 63, the mechanical clamp 61 includes two openable and closable mechanical arms 64, the mechanical arm 64 is connected with the opening and closing cylinder 62, and the driving end of the opening and closing cylinder 62 is fixedly connected with the horizontal moving cylinder 63. When the front traction device 11 pulls the latch 104 to insert into the block 103, there may be a case that the latch 104 is not inserted to the bottom, so that the chain tooth cannot be accurately positioned, affecting the chain. Through the arrangement of the latch safety device, when the latch is pulled by the front traction device to insert into the block, the mechanical clamp 61 clamps the belt of the latch sub-chain 102, and then the horizontal moving cylinder 63 sends the latch inward, so that the latch 104 is inserted to the position.

[0062] The front of the block positioning device 3 is provided with a chain clamp 7 and a chain clamp cylinder 71 that drives the chain clamp 7 to open and close. The chain clamp 7 is provided with a chain passage 72, and the thickness of the chain 10 is less than the thickness of the chain passage 72 and the thickness of the puller 109. By setting the chain clamp 7, the position of the puller and the length of the chain can be adjusted after the puller comes out of the chain device.

[0063] Working principle:

[0064] First, the zipper chain machine puts the zipper puller 109 on the chain 10 with a stop bevel, fixes the zipper puller 109 in the puller fixing groove 34, and then the rear traction device 12 pulls the chain 10 to move backward until the block 103 moves into the block fixing groove 33. Since the block fixing groove 33 and the puller fixing groove 104 are adjacent, the block 103 is tightly attached to the puller 109. At this time, the sensing needle 35 controls the positioning cylinder 36 to drive the positioning block 37 to extend and press the block 103, so that the block 10 is fixed.

[0065] Then the left and right cylinders 43 control the pin split chain moving plate 41 to move to the right (towards the block split chain 101 direction), because the initial position of the pin split chain moving plate 41 is located above the horizontal line of the block split chain 101, so the pin 104 is located above the block 103 after moving to the right. Then the lifting cylinder 54 controls the pressing wheel 51 corresponding to the block split chain 101 to lift, so that the rear traction wheel 121 loses the traction force of the block split chain 101. When the rear traction wheel 121 rotates, only the pin split chain 102 retreats, so that the pin 104 retreats to the upper rear of the block 103. Then the up and down cylinder 42 controls the pin split chain moving plate 41 to move down, so that the pin 104 is located behind the block 103 and the puller socket (the reason for moving the chain from top to bottom is that there is a knife edge 107 in front of the pin 104, which can bend the chain 10 in front of the pin 104 through the knife edge 107, so that the pin 104 can be aligned with the socket); then the front traction device 11 controls the chain 10 to move forward to make the pin 104 inserted into the socket of the puller 109 and the block 103.

[0066] During the forward movement of the pin 104, the pin safety device 6 can also be set, that is, when the pin 104 is inserted into the block 103 by the forward movement of the chain 10 controlled by the front traction device 11, the mechanical clamp 61 of the pin safety device clamps the cloth tape of the pin split chain 102, and then the transverse cylinder 63 moves the pin split chain 102 forward, so that the pin 104 is forced to the bottom of the block 103, ensuring that the pin 104 is inserted in place. The pin safety device 6 is not necessary, and the existence of the pin safety device 6 increases stability.

[0067] After the insertion of the pin 104 into the block 103, the positioning cylinder 36 drives the positioning block 37 to retract, the mechanical clamp 61 opens the clamp, the compression wheel 51 of the block split chain 101 lowers the compression, then the front traction device 11 drives the chain belt 10 to move forward by a distance, because of the opening in front of the block fixing groove 33, the block 103 and the pin 104 move forward, and the puller 109 is still in the puller fixing groove 34, thus the chain splicing action is completed. After the chain splicing by a distance, the chain splicing platform 31 lowers, the puller 109 leaves the puller fixing groove 34, the front traction device 11 continues to drive the chain belt 10 to move forward, and when the block 103 passes through the chain splicing clamp 7, the chain splicing clamp 7 is closed, the puller 109 is against the back of the chain splicing clamp 7, and in the process of moving forward of the chain belt 10, the distance of the chain splicing can be controlled as needed, and when the distance reaches the set distance, the chain splicing clamp 7 is opened, and finally the front traction device 10 continues to move forward, and waits for the next puller 109 to pass through the chain, so as to realize the automation of the chain splicing by reciprocating.

[0068] The present application has the characteristics of being able to apply to the chain splicing of the puller after the upper and lower stoppers are injection molded and the puller is inserted, complete the automatic chain splicing process, and improve the production efficiency.

[0069] The above embodiments are only the preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
