Description

TECHNICAL FIELD

[0001] The application belongs to the field of zipper machines, and relates to a zipper tape upper stop tape bevel port chain threading and chain integrated machine. BACKGROUND

[0002] The zipper chain threading machine is used for installing the puller into the zipper tape and automatically producing the complete zipper. The equipment needs to transport the puller to the upper puller mold first, and then deliver the puller to the zipper tape channel through the upper puller mold, and complete the action of threading the puller into the zipper tape through a series of actions.

[0003] The traditional zipper forming mode first forms the lower stop of the zipper tape, then completes the upper puller action through the chain threading machine, and then forms the front upper stop, so that two times of injection molding are required. The present zipper tape upper stop tape bevel port chain threading and chain integrated machine can form the upper stop and the lower stop at one time, form the bevel port on the upper stop, and complete the upper puller work through the bevel port, so that the process steps are reduced, and the production line length is reduced.

Through the setting of the chain connection clamp 57, the position of the puller and the length of the chain connection can be adjusted after the puller comes out of the chain connection device.

[0078] Working principle:

[0079] The patent application is applicable to a chain belt which has been simultaneously formed with an upper stop 105 and a lower stop. The chain insertion action is realized by forming a bevel 106 on the upper stop 105 for the puller to pass through. The chain belt includes two chain belts, namely a block chain 101 and a pin chain 102. The lower stop of the block chain for chain insertion is formed with a block 103, and the upper stop is formed with a bevel 106. The lower stop of the pin chain 102 is a pin 104, and the upper stop is a normal upper stop.

[0080] When the chain belt 10 enters the device, it is in a chain state. The block chain 101 with a bevel passes through a block chain passage 21, and the pin chain 102 passes through a pin chain passage 22. The block chain passage 21 is provided with a sensing wheel 313. When the block of the block chain 101 passes under the sensing wheel 313 during the forward movement of the chain belt, the sensing wheel 313 rotates through a first connecting rod 312. A sensing switch 311 detects the rotation of the first connecting rod 312, so as to control the chain belt traction mechanism to stop traction. At this time, the chain belt 10 stops moving.

[0081] Then the second cylinder 332 controls the positioning clamp 321 to extend to the block sub-chain 101, and then the clamp cylinder 341 controls the positioning clamp 321 to retract, at this time the positioning clamp 321 is in the transition section 109 between two sections of chain belts, that is, in the cloth belt 110 between the block 103 of the previous section of block sub-chain and the upper stop 105 of the next section, the transition section 109 is provided in the chain belt through slot 324 of the positioning clamp 321. The first cylinder 331 controls the positioning clamp 321 to advance, when advancing, the side of the positioning clamp 321 abuts against the rear end of the upper stop 105 and advances together with the upper stop 105 (the chain belt also advances), and finally is positioned to the set position, that is, the side of the puller fixing groove 423 of the upper puller die 42 (that is, the side of the puller), so that the bevel 106 of the upper stop faces the entrance position of the puller 9.

[0082] Then the up-down driving cylinder 451 drives the upper puller die 42 to ascend to the set position (the puller 9 has been sent into the puller fixing groove 423 by the puller feeding device such as a vibrating disc), then the rotating cylinder 441 controls the puller base 41 to rotate 20-30°, so that the entrance of the puller 9 is parallel to the bevel 106, and the safety cylinder controls the puller to pull down the pull ring to open the safety.

[0083] Then the push block cylinder 352 drives the push block 351 to move to laterally push the bevel 106 of the upper stop into the entrance of the puller 9, then the clamp cylinder 341 controls the positioning clamp 321 to open, the second cylinder 332 and the first cylinder 331 control the positioning clamp 321 to reset, the push block 351 resets, then the rear traction device 12 drives the chain belt 10 to retreat, in the process of retreating, the upper puller die 42 rotates to the normal position, and the puller 9 enters the chain belt through the bevel to complete the chain penetration.

[0084] Then the rear traction device 12 pulls the chain belt to move backward until the block 103 moves into the block fixing groove 422, since the block fixing groove 422 and the puller fixing groove 423 are adjacent, the block 103 tightly abuts against the puller 9. At this time, the sensing ejector pin 512 controls the positioning cylinder 513 to drive the positioning block 514 to extend to press the block 103, so that the block 103 is fixed.

[0085] Then the left and right air cylinders 522 control the pin chain moving plate 53 to move right, because the initial position of the pin chain moving plate 53 is higher than the position of the block chain 101, so the right-moving pin 104 is above the block 103, then the lifting cylinder 554 controls the corresponding block chain 101 to lift the compression wheel 551, so that the rear traction wheel 121 loses the traction force of the block chain 101, and when the rear traction wheel 121 rotates, only the pin chain 102 retreats, so that the pin 104 retreats to the rear upper side of the block 103, then the up and down air cylinder 521 controls the pin chain moving plate 53 to move down, so that the pin 104 is located behind the block 103 and the puller 9 port (the reason for moving the chain 10 from top to bottom to align the pin 104 with the block 103 port is that there is a knife edge 107 in front of the pin 104, which can facilitate the bending of the cloth belt 110 in front of the pin 104 through the knife edge 107, so as to facilitate the alignment of the pin 104 with the block 103 port); then the front traction device 11 controls the chain 10 to move forward to make the pin 104 inserted into the port of the block 103 and the block 9.

[0086] During the forward movement of the pin 104, the pin safety device 56 can also be provided, that is, when the front traction device 11 controls the chain 10 to move forward to make the pin 104 inserted into the block 103, the mechanical clamp 561 of the pin safety device 56 clamps the cloth belt 110 of the pin chain 102, and then the pin chain 102 is moved forward by the horizontal moving cylinder 563, so that the pin 104 is forced to the bottom of the block 103, to ensure that the pin 104 is inserted in place. The pin safety device 56 is not necessary, and the presence of the pin safety device 56 increases stability.

[0087] After the pin 104 is inserted into the block 103, the positioning cylinder 513 drives the positioning block 514 to retract, the mechanical clamp 561 opens the clamp, the compression wheel 551 of the block chain 101 is lowered and presses the rear traction wheel 121, then the front traction device 11 drives the chain 10 to move forward a distance, because of the opening in front of the block fixing groove 422, the block 103 and the pin 104 move forward, while the puller 9 is still in the puller fixing groove 423, thereby completing the chain operation. After a certain distance of chain, the upper puller mold 42 is lowered, the puller 9 leaves the puller fixing groove 423, the front traction device 11 continues to drive the chain 10 to move forward, and when the block 103 passes through the chain clamp 57, the chain clamp 57 is closed, the puller 9 is located behind the chain clamp 57, and the distance of the chain can be controlled during the forward movement of the chain 10, and when the distance reaches the set distance, the chain clamp 57 is opened, and finally the front traction device 11 continues to move forward, and waits for the next block 103 of the block chain 101 to reach the position of the induction wheel 313, so as to realize the automation of the chain and the chain.

[0088] The present application has the characteristics of being capable of completing the chain pulling and chain combining of the puller after the upper stop has been injection molded, thereby completing the automatic production and improving the production efficiency.

[0089] 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 within the protection scope of the present application.
