As shown in fig. 1 and 2, the frame 1 is provided with a second chain belt positioning assembly 22 and a pin hole assembly 7 above the second chain belt positioning assembly 22 between the block pin installation assembly and the chain belt traction assembly 5.

Further, as shown in fig. 3 to 6, the block plug pin mounting assembly includes two clamping and pushing mechanisms 4, wherein one clamping and pushing mechanism 4 is used for mounting a block, and the other clamping and pushing mechanism 4 is used for mounting a plug pin; the clamping and pushing mechanism 4 comprises a pushing driving cylinder 41 which is arranged on the frame 1 and horizontally moves back and forth, a pushing movable frame 42 is arranged at the driving end of the pushing driving cylinder 41, an automatic clamping jaw 43 is arranged on the pushing movable frame 42, and the automatic clamping jaw 43 comprises a fixed clamping block 431 which moves in an opening and closing manner and a movable clamping block 432 which is arranged above the fixed clamping block 431.

Further, as shown in fig. 1 to 4, the universal type zipper block latch machine further comprises a clip assembly 6, and when the block latch mounting assembly mounts the block latch to the corresponding zipper center line position of the zipper belt, the automatic clamping jaw 43 keeps clamping the block latch, and the clip assembly 6 acts and pushes down the movable clamping block 432, so that the movable clamping block 432 presses the block latch to the corresponding zipper center line position of the zipper belt.

It should be explained that, the first chain belt positioning assembly 21 and the second chain belt positioning assembly 22 of the first embodiment are used for positioning the chain belts respectively, and the specific structure and the specific working mode of the chain belt positioning assembly have been disclosed in the prior art, which are not described herein. In other words, the chain belt pulling assembly 5 of the first embodiment is used for pulling the chain belt to move from front to back, and the specific structure and the specific working mode of the chain belt pulling assembly 5 have been disclosed in the prior art, which are not described herein.

In the process of realizing the block and bolt installation by using the block bolt installation assembly of the first embodiment, the first chain belt positioning assembly 21 firstly positions the chain belts, then one clamping and pushing mechanism 4 clamps the block by the fixed clamping block 431 and the movable clamping block 432 of the automatic clamping jaw 43, and the other clamping and pushing mechanism 4 clamps the bolt by the fixed clamping block 431 and the movable clamping block 432 of the automatic clamping jaw 43; when the clamped square blocks and bolts are arranged on the woven belts of the chain belts fixed by the first chain belt positioning assembly 21, the pushing driving cylinders 41 respectively push the corresponding pushing movable frames 42 forward, and the pushing movable frames 42 respectively drive the corresponding automatic clamping jaws 43 to move forward, so that the clamped square blocks and bolts are respectively inserted into the corresponding central line parts of the chain belts; after the square block and the bolt are pushed forward to the right position, the clamp assembly 6 acts, the automatic clamping jaw 43 keeps clamping the square block or the bolt, the clamp assembly 6 acts and pushes down the movable clamping block 432, so that the movable clamping block 432 tightly presses the square block or the bolt on the corresponding central line part of the zipper belt.

It should be noted that, in this embodiment, the movable clamping blocks 432 are pressed to clamp the central line of the zipper belt by the square or bolt, and the automatic clamping jaw 43 of each clamping and pushing mechanism 4 keeps clamping the corresponding square or bolt during the pressing process of the square or bolt, so that the stable positions of the square or bolt during the pressing process can be effectively ensured; compared with the clamping mode of the edge part during the installation of the square bolt in the prior art, the first embodiment has better stability and reliability.

In the working process of the universal zipper block plug machine of the first embodiment, after the first chain belt positioning component 21, the block plug mounting component and the clip punching component 6 are matched and the block plug is mounted, the chain belt with the block plug mounted thereon is positioned by the second chain belt positioning component 22, and then the needle punching component 7 performs the needle punching processing so as to perform the needle punching reinforcement on the back surfaces of the block and the plug. It should be noted that, after the front side of the chain belt passes through the first chain belt positioning assembly 21 and the installation of the square bolt is completed, the worker can turn over and convey the chain belt and make the back side of the chain belt pass through the second chain belt positioning assembly 22 upwards, so as to punch needle holes on the back sides of the square bolt through the needle hole punching assembly 7; after the fastener tape back face is upward passed through the first fastener tape positioning assembly 21 and the block pin installation is completed, the worker can directly pass the fastener tape through the second fastener tape positioning assembly 22 without turning over, so as to punch the pin holes on the block, pin back face through the pin hole punching assembly 7. Therefore, the universal block latch machine for the zipper of the first embodiment can be used for installing the block latches of the left-inserted zipper and the right-side zipper in a universal manner, and has strong universality.

It should be further emphasized that, since the universal zipper block latch machine of the first embodiment performs the punching and compaction not at the block latch installation position, but the compaction of the block and the latch is realized by pressing the movable clamping block 432 of the automatic clamping jaw 43, the block latch installation versatility of the left-inserted zipper and the right-inserted zipper can be realized only by changing the conveying direction of the zipper belt (selecting right-side upward conveying or back upward conveying) under the condition that the clamping and pushing mechanism 4 is kept unchanged; for example, when right side up transport is the block pin installation for the left side insert zipper, the block pin installation for the right side insert zipper can be achieved by adjusting to back side up transport. Therefore, the universal zipper block latch machine of the first embodiment can realize the universality of the left-side zipper and the right-side zipper, namely, a zipper manufacturer can simultaneously process the left-side zipper and the right-side zipper by only one piece of equipment, so that the purchase cost of the zipper production equipment is reduced.
