Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of zipper production and processing equipment, and in particular to a clamping block pin device. Background Technology
[0002] A zipper consists of two webbing strips (a left webbing strip and a right webbing strip). The inner edges of both strips are fitted with sequentially spaced teeth along their center lines. One strip has a pin at one end, and the other has a square at one end. When the zipper is closed, the pin is inserted into the corresponding slot in the square. Depending on the pin's position, the zipper can be either a left-side or right-side insertion zipper. For a left-side insertion zipper, the pin is located on the left webbing strip; for a right-side insertion zipper, the pin is located on the right webbing strip.
[0003] Furthermore, zippers can be categorized into metal zippers and nylon zippers based on the material of their teeth. For metal zippers, the teeth on each webbing are symmetrically arranged, and the teeth are exposed on both the front and back of the zipper. For nylon zippers, the teeth on each webbing are located on one side, and the teeth are only exposed on the front of the zipper.
[0004] In the zipper manufacturing process, two webbings form a chain structure, and both webbings are equipped with teeth, with the teeth meshing with each other. The chain consists of zipper units arranged at intervals, with gaps between adjacent zipper units (the gaps are where the teeth are not installed, commonly known as sizing holes). The chain is finally cut by a cutting device to form individual zippers.
[0005] In addition, for the square pin zipper, in order to ensure that the square and pin are stably connected to the center line of the webbing edge on the corresponding side, the back of the square and pin need to be reinforced by punching holes; two holes need to be punched on the square and one hole needs to be punched on the pin.
[0006] It should be noted that in the existing technology, zippers use a block pin machine to install the blocks and pins on the zipper belt. A Chinese utility model patent with patent number ZL202120052354.6 and titled "A Zipper Block Pin Machine" describes a zipper block pin machine that includes a frame. The frame is equipped with a chain feeder, a chain positioning component, a pressing and punching component, a block pin installation component, and a chain traction component, arranged sequentially from front to back along the chain conveying direction. A block feeding component is installed on the left side of the block pin installation component, and a pin feeding component is installed on the right side. The block pin installation component includes a lifting frame, and the frame is equipped with a corresponding lifting frame. The device includes a lifting drive cylinder that moves up and down, with its drive end connected to a lifting movable frame. The upper end of the lifting movable frame is equipped with a horizontal drive cylinder that moves left and right horizontally. The drive end of the horizontal drive cylinder is equipped with a horizontal movable frame, which is also equipped with a pushing movable frame. The rear end of the horizontal movable frame is equipped with a pushing drive cylinder that moves forward and backward horizontally, with its drive end connected to the pushing movable frame. The pushing movable frame is equipped with a block clamping gripper and a pin clamping gripper located on the right side of the block clamping gripper and spaced apart from it.
[0007] For the aforementioned zipper block and pin installation machine, during the block and pin installation process, the chain feeder continuously releases the chain, which moves from front to back under the traction of the chain traction component. When block and pin installation is required, the chain positioning component first positions the chain, the block feeding component automatically feeds the blocks to the block and pin installation component, and the pin feeding component automatically feeds the pins to the block and pin installation component. The block and pin installation component then installs the blocks and pins sequentially onto the chain. After the blocks and chain are installed, the clamping and drilling component performs clamping and drilling operations on the back of the blocks and pins respectively, so that the blocks and pins are securely fastened to the chain. During the clamping and drilling operation, the block clamping gripper holds the blocks, and the pin clamping gripper holds the blocks.
[0008] It should be noted that the aforementioned zipper block pin machine has the following defects, specifically:
[0009] Defect 1: Since the pin holes can only be made on the back of the square and pin, meaning the pin hole position is directional, one machine can only be used for a specific type of zipper. For left-insertion zippers and right-insertion zippers, two different models are required, which increases the equipment purchase cost for zipper manufacturers. The only difference between the square pin machine for left-insertion zippers and the square pin machine for right-insertion zippers is the feeding position of the square and pin and the pushing and installing position.
[0010] Defect 2: During the process of pressing and fixing blocks and pins by pressing and fixing the blocks and pins using the pressing and fixing assembly, in order to ensure that the pressing and fixing action is not voided, the clamping gripper is withdrawn before pressing and fixing and pressing, resulting in poor clamping stability and reliability; the blocks and pins are prone to misalignment when pressing and fixing, resulting in poor product stability. Utility Model Content
[0011] The purpose of this utility model is to provide a clamping block pin device to address the shortcomings of the existing technology. This clamping block pin device has a novel structural design, good stability and reliability, and strong versatility.

The lifting adjustment screw is located below the movable base, and the lower end of the movable base has a screw clearance hole with a downward opening corresponding to the lifting adjustment screw. The upper end of the lifting adjustment screw extends into the screw clearance hole of the movable base.
[0029] The lifting adjustment screw is fitted with a support nut, and the movable seat rests against and is supported by the upper surface of the support nut;
[0030] The fixed seat has a vertically extending lifting guide groove, and the movable seat has a lifting guide rail that is slidably installed in the lifting guide groove.
[0031] The pressing block driving mechanism includes a pressing block driving motor and a pressing block driving shaft mounted on the clamp mounting base, wherein the power output shaft of the pressing block driving motor is drivingly connected to the pressing block driving shaft.

[0041] The frame is also equipped with a feeding vibratory feeder on the side of the feeding receiving block, and the discharge port of the feeding vibratory feeder is connected to the feeding groove of the feeding receiving block.
[0042] During operation, the feeding vibratory feeder feeds blocks or pins one by one into the feeding groove of the feeding receiving block. The push rod drive cylinder drives the feeding push rod to move so that the blocks or pins falling into the feeding groove are fed into the corresponding clamping and pushing mechanism.
[0043] Compared with the prior art, the present invention has the following beneficial effects:
[0044] 1. Since the pushing height of each clamping and pushing mechanism remains unchanged when the blocks and pins are installed on the corresponding zipper centerline of the chain belt; since the positions of the chain teeth of metal zippers and nylon zippers are different, the clamping block and pin device of this utility model can adaptively adjust the height of the chain belt positioning component so that the corresponding zipper centerline of the chain belt is aligned with the clamping and pushing mechanism. That is, this utility model can be applied to the installation of blocks and pins on metal zippers and nylon zippers, and has strong adaptability and versatility.
[0045] 2. By pressing down on the movable clamping block, the block or pin clamps the corresponding zipper centerline of the chain. During the clamping process, the automatic grippers of each clamping and pushing mechanism keep holding the corresponding block or pin, which can effectively ensure the stability of the block or pin position during clamping. Compared with the existing technology of clamping and reinforcing after the block or pin is inserted into place, this utility model has better stability and reliability.
[0046] 3. This utility model does not use needle holes to press the blocks and pins onto the corresponding zipper centerline of the zipper belt. Instead, it uses the movable clamping block of the automatic gripper to press the blocks and pins together. With the clamping and pushing mechanism remaining unchanged, simply changing the conveying direction of the zipper belt (either front-facing or back-facing) allows for universal installation of blocks and pins for both left-side and right-side zipper insertion. In other words, the clamping block and pin device of this utility model can be used for both left-side and right-side zipper insertion. This means that zipper manufacturers only need one machine to simultaneously process both left-side and right-side zipper insertions, thereby reducing the purchase cost of zipper production equipment.
[0047] 4. The clamping block pin device of this utility model has the advantages of novel structural design, good stability and reliability, and strong versatility. Attached Figure Description

Detailed Implementation
[0066] The present invention will now be described in conjunction with specific embodiments.
[0067] Example 1, as Figures 1 to 3 As shown, a clamping block pin device includes a frame 1, on which a chain positioning assembly 2 and a block pin mounting assembly are arranged sequentially from front to back along the chain conveying direction.
[0068] Among them, such as Figure 1 As shown, the frame 1 is equipped with a lifting adjustment seat 3 corresponding to the chain positioning component 2, and the chain positioning component 2 is installed on the lifting adjustment seat 3; the lifting adjustment seat 3 can realize lifting adjustment to realize the height adjustment of the chain positioning component 2.
[0069] Furthermore, such as Figures 1 to 5 As shown, the block pin mounting assembly includes two clamping and pushing mechanisms 4, one of which is used to mount the block and the other is used to mount the pin.
[0070] Specifically, the clamping and pushing mechanism 4 includes a pushing drive cylinder 41 mounted on the frame 1 and moving horizontally back and forth. The driving end of the pushing drive cylinder 41 is equipped with a pushing movable frame 42. The pushing movable frame 42 is equipped with an automatic gripper 43. The automatic gripper 43 includes a fixed clamping block 431 that opens and closes, and a movable clamping block 432 located above the fixed clamping block 431.
[0071] Furthermore, the clamping block pin device also includes a clamping assembly 5, which includes a clamping mounting base 51 mounted on the frame 1. The clamping mounting base 51 is equipped with a clamping pressure block 52 and a pressure block drive mechanism 53 for driving the clamping pressure block 52 to move up and down.
[0072] It should be noted that during operation, when the block and pin installation assembly installs the block and pin onto the webbing of the chain belt, the automatic gripper 43 holds the block or pin in place, and the pressure block drive mechanism 53 drives the clamping block 52 to move downward and press the movable clamping block 432 downward, so that the movable clamping block 432 moves further toward the fixed clamping block 431 and presses the block or pin tightly against the corresponding zipper centerline of the chain belt.
[0073] It should be explained that the chain positioning component 2 in this embodiment is used to position the chain. The specific structure and working method of the chain positioning component 2 have been disclosed in the prior art, and will not be repeated here.
[0074] It should be further explained that the clamping block pin device of this embodiment is applied to the pin-locking block machine; accordingly, the pin-locking block machine is equipped with a chain feeder on the front side of the clamping block pin device of this embodiment, and a chain traction assembly is equipped on the rear side of the clamping block pin device of this embodiment; during operation, the chain feeder continuously feeds out the chain, and the chain feeder feeds out the chain feeder moves from front to back under the traction of the chain traction assembly, so as to realize that the continuous chain feed passes through the chain positioning assembly 2 and the block pin installation assembly in sequence.
[0075] In the process of installing blocks and pins using the clamping block and pin device of this embodiment, the chain positioning component 2 first positions the chain. Then, one of the clamping and pushing mechanisms 4 clamps the block using the fixed clamping block 431 and movable clamping block 432 of its automatic gripper 43, and the other clamping and pushing mechanism 4 clamps the pin using the fixed clamping block 431 and movable clamping block 432 of its automatic gripper 43. When the clamped block and pin are installed on the webbing of the chain positioned by the chain positioning component 2, each pushing drive cylinder 41 pushes the corresponding pushing movable frame 42 forward, and each pushing movable frame 42 drives the corresponding automatic gripper 43 to move forward, so that the block and pin are installed on the chain. The clamped blocks and pins are inserted into the corresponding zipper centerline positions of the chain belt. After the blocks and pins are pushed forward into place, the clamping assembly 5 is activated. During this process, the pressure block drive mechanism 53 drives the clamping pressure block 52 to move downward and presses the movable clamping block 432 downward, so that the movable clamping block 432 moves further toward the fixed clamping block 431. Since the blocks or pins are clamped between the corresponding fixed clamping block 431 and the movable clamping block 432, the blocks and pins are pressed tightly during the further downward movement of the movable clamping block 432, so that the blocks or pins are pressed tightly against the corresponding zipper centerline positions of the chain belt, thereby completing the installation of the blocks and pins.
[0076] It should be emphasized that, since the pushing height of each clamping and pushing mechanism 4 remains unchanged when the blocks and pins are installed on the corresponding zipper centerline of the chain belt; since the positions of the chain teeth of metal zippers and nylon zippers are different, the clamping block and pin device of this embodiment can adaptively adjust the height of the chain belt positioning component 2 so that the webbing of the chain belt is aligned with the clamping and pushing mechanism 4. That is, this embodiment can be applied to the installation of block pins on metal zippers and nylon zippers, and has strong adaptability and versatility.
[0077] Furthermore, in this embodiment, the movable clamping block 432 is used to press the block or pin to clamp the corresponding zipper centerline of the chain. During the pressing process of the block and pin, the automatic grippers 43 of each clamping and pushing mechanism 4 keep clamping the corresponding block and pin. This can effectively ensure the stability of the position of the block and pin during pressing. Compared with the existing technology of inserting the block and pin into place and then retracting the clamp for reinforcement, this embodiment has better stability and reliability.
[0078] It should be further emphasized that, since the clamping block and pin device in this embodiment does not press the block and pin onto the corresponding zipper centerline of the chain by punching holes, but rather achieves the clamping of the block and pin by pressing the movable clamping block 432 of the automatic clamping claw 43, the installation of the block and pin for both left-inserted chain belts and right-inserted zippers can be universally achieved by simply changing the conveying direction of the chain belt (selecting front-up conveying or back-up conveying). For example, when front-up conveying is used to install the block and pin for left-inserted zippers, simply adjusting to back-up conveying and adaptively adjusting the height of the lifting adjustment seat 3 can achieve the installation of the block and pin for right-inserted zippers. Therefore, the clamping block and pin device in this embodiment can achieve universal use for both left-inserted and right-inserted zippers, meaning that zipper manufacturers only need one machine to simultaneously meet the processing requirements for left-inserted and right-inserted zippers, thereby reducing the purchase cost of zipper production equipment.
[0079] In summary, the clamping block pin device of this embodiment has the advantages of novel structural design, good stability and reliability, and strong versatility through the above structural design.
[0080] Example 2, as Figures 6 to 8 , Figure 15 As shown, the difference between this embodiment 2 and embodiment 1 is that: the movable clamping block 432 is equipped with a top-pressing contact block 433, and the movable clamping block 432 has an upward-opening contact block mounting groove 4321 corresponding to the top-pressing contact block 433 above the clamping position. The lower end of the top-pressing contact block 433 is slidably installed in the contact block mounting groove 4321 of the movable clamping block 432, and the upper end of the top-pressing contact block 433 extends to the top of the movable clamping block 432; a compression spring 434 is installed in the contact block mounting groove 4321 of the movable clamping block 432, the upper end of the compression spring 434 abuts against the top-pressing contact block 433, and the lower end of the compression spring 434 abuts against the movable clamping block 432.
[0081] Furthermore, to prevent the top-pressing contact block 433 from exiting the contact block mounting groove 4321 of the movable clamping block 432, the second embodiment can adopt the following limiting structure design. Specifically, the movable clamping block 432 is equipped with a contact block limiting member 435, and the contact block limiting member 435 has a vertical through-hole 4351 corresponding to the top-pressing contact block 433. The top-pressing contact block 433 passes through the limiting through-hole 4351 of the contact block limiting member 435 from bottom to top. The top-pressing contact block 433 is provided with a contact block shoulder 4331 located below the contact block limiting member 435. When the top-pressing contact block 433 moves upward relative to the movable clamping block 432 to the upper limit position, the contact block shoulder 4331 of the top-pressing contact block 433 abuts against and is limited by the contact block limiting member 435.
[0082] During the action of the clamping assembly 5 and the downward movement of the movable clamping block 432, the downward-moving clamping block 52 first contacts the pressing contact block 433, causing the pressing contact block 433 to move downward. Since there is a compression spring 434 structure between the pressing contact block 433 and the movable clamping block 432, the movable clamping block 432 can elastically press the block or pin by pressing the pressing contact block 433 downward.
[0083] Example 3, as Figure 6 and Figure 8 , Figure 15 As shown, the difference between this embodiment 3 and embodiment 1 is that: the fixed clamping block 431 of the automatic gripper 43 is screwed and fastened to the front end of the pusher frame 42, the pusher frame 42 is pivotally mounted with a movable swing arm 436, and the movable clamping block 432 is installed at the front end of the movable swing arm 436; a gripper drive cylinder 437 is installed above the rear end of the pusher frame 42 on the movable swing arm 436, and the drive end of the gripper drive cylinder 437 is connected to the rear end of the movable swing arm 436.
[0084] It should be explained that the clamping positions of the fixed clamping block 431 and the movable clamping block 432 are respectively provided with contoured clamping grooves. For the clamping and pushing mechanism 4 used to install the block, the contoured clamping grooves of its fixed clamping block 431 and movable clamping block 432 are consistent with the shape of the block; for the clamping and pushing mechanism 4 used to install the pin, the contoured clamping grooves of its fixed clamping block 431 and movable clamping block 432 are consistent with the shape of the pin. Through the above-mentioned contoured clamping groove design, this embodiment 3 can enable the fixed clamping block 431 and movable clamping block 432 to stably and accurately clamp the block or the pin.
[0085] When the block or pin has not entered between the fixed clamping block 431 and the movable clamping block 432, the gripper drive cylinder 437 drives the movable swing arm 436 to move and cause the movable clamping block 432 to open relative to the fixed clamping block 431; when the fixed clamping block 431 and the movable clamping block 432 cooperate and clamp the block or pin, the gripper drive cylinder 437 drives the movable swing arm 436 to move and cause the movable clamping block 432 to close relative to the fixed clamping block 431.
[0086] It should be noted that when the clamping assembly 5 is activated and the block and pin are pressed and fixed to the corresponding zipper centerline of the chain, the clamping block 52 will cause the movable clamping block 432 to move further toward the fixed clamping block 431. During this process, the rear end of the movable swing rod 436 will adaptively tilt upward and react on the piston rod of the gripper drive cylinder 437. At this time, the piston of the gripper drive cylinder 437 will adaptively perform a return stroke.
[0087] Example 4, as Figure 9As shown, the difference between this embodiment four and embodiment one is that the block pin mounting assembly further includes a block pin mounting bracket 45. The block pin mounting bracket 45 includes a mounting bracket base 451 mounted on the frame 1. A mounting bracket top seat 452 is mounted on the upper side of the mounting bracket base 451. A mounting bracket cylinder 453 that moves along the direction perpendicular to the chain conveying direction is mounted on the upper end of the mounting bracket base 451. The drive end of the mounting bracket cylinder 453 is connected to the mounting bracket top seat 452, and two clamping and pushing mechanisms 4 are respectively mounted on the mounting bracket top seat 452.
[0088] It should be noted that during the installation of the block and pin in the block and pin installation assembly of Embodiment 1, the two clamping and pushing mechanisms 4 are located on both sides of the center of the chain belt. The clamping and pushing mechanism 4 for installing the pin first operates and installs the pin at the corresponding zipper centerline of the chain belt. After the clamping assembly 5 operates and presses the pin against the corresponding zipper centerline of the chain belt, the clamping and pushing mechanism 4 for installing the pin resets and retracts from the pressed pin. Then, the clamping and pushing mechanism 4 for installing the block operates again and installs the block at the corresponding zipper centerline of the chain belt. After the clamping assembly 5 operates and presses the block against the corresponding zipper centerline of the chain belt, the clamping and pushing mechanism 4 for installing the block resets and retracts from the pressed block. For the block pin installation assembly in this embodiment, since the two clamping and pushing mechanisms 4 are located on both sides of the center of the chain, in order to avoid interference when the two clamping and pushing mechanisms 4 are in operation, the automatic gripper 43 of the clamping and pushing mechanism 4 used to install the block can only clamp part of the block, and the clamping stability and reliability are not enough.
[0089] For the block pin mounting assembly of this embodiment four, during its operation, the mounting frame cylinder 453 drives the mounting frame top seat 452 to move, thereby achieving the shifting and switching of the two clamping and pushing mechanisms 4. Specifically: before the clamping and pushing mechanism 4 for installing the pin moves and installs the pin at the corresponding zipper centerline position of the chain, the mounting frame cylinder 453 moves and aligns the clamping and pushing mechanism 4 for installing the pin with the corresponding zipper centerline position of the chain; after the pin is installed, the mounting frame cylinder 453 drives the mounting frame top seat 452 and the two clamping and pushing mechanisms 4 to move horizontally, so that the clamping and pushing mechanism 4 for installing the block is aligned with the corresponding zipper centerline position of the chain. Through the design of the block pin mounting frame 45 in this embodiment four, this embodiment four can avoid the problem of interference when the two clamping and pushing mechanisms 4 move, and can make the automatic gripper 43 of the clamping and pushing mechanism 4 for installing the block clamp the entire block, resulting in better clamping stability and reliability.
[0090] Example 5, as Figure 13 and Figure 14As shown, the difference between this fifth embodiment and the first embodiment is that the lifting adjustment seat 3 includes a fixed seat 31 that is screwed and fastened to the frame 1, and a movable seat 32 is slidably mounted on the fixed seat 31. The chain positioning assembly 2 is mounted on the upper end of the movable seat 32.
[0091] A lifting and adjusting mechanism 33 is installed between the movable seat 32 and the fixed seat 31.
[0092] Specifically: The lifting adjustment mechanism 33 includes a lifting adjustment screw 331 mounted on the fixed base 31 and arranged vertically. The lifting adjustment screw 331 is located below the movable base 32, and the lower end of the movable base 32 has a screw clearance hole with a downward opening corresponding to the lifting adjustment screw 331. The upper end of the lifting adjustment screw 331 extends into the screw clearance hole of the movable base 32. The lifting adjustment screw 331 is screwed with a support nut 332, and the movable base 32 abuts against and supports the upper surface of the support nut 332. The fixed base 31 has a vertically extending lifting guide groove 333, and the movable base 32 is provided with a lifting guide rail 334 that is slidably installed in the lifting guide groove 333.
[0093] During the adaptive adjustment of the height of the chain positioning component 2, the operator also needs to rotate the support nut 332. Since the support nut 332 is screwed onto the lifting adjustment screw 331, the support nut 332 moves up and down relative to the lifting adjustment screw 331. Since the movable seat 32 remains in contact with the upper surface of the support nut 332, the movable seat 32 moves up and down adaptively when the support nut 332 moves up and down relative to the lifting adjustment screw 331, so as to realize the adaptive adjustment of the height position of the chain positioning component 2.
[0094] Example 6, as Figures 10 to 12 As shown, the difference between this embodiment six and embodiment one is that the pressing block drive mechanism 53 includes a pressing block drive motor 531 and a pressing block drive shaft 532 mounted on the clamp mounting base 51, and the power output shaft of the pressing block drive motor 531 is drivenly connected to the pressing block drive shaft 532.
[0095] The pressing block driving mechanism 53 further includes a first driving slider group 533 and a second driving slider group 534 that are slidably mounted on the clamp mounting base 51. The first driving slider group 533 includes a first upper driving slider 5331 and a first lower driving slider 5332 that is adjustablely mounted on the lower end of the first upper driving slider 5331. The second driving slider group 534 includes a second upper driving slider 5341 and a second lower driving slider 5342 that is adjustablely mounted on the lower end of the second upper driving slider 5341.
[0096] Furthermore, an eccentric drive rod 535 is installed at the end of the pressure block drive shaft 532. A first drive connecting rod 5361 is installed between the eccentric drive rod 535 and the upper end of the first upper drive slider 5331. The two ends of the first drive connecting rod 5361 are pivotally connected to the eccentric drive rod 535 and the upper end of the first upper drive slider 5331, respectively. A second drive connecting rod 5362 is installed between the eccentric drive rod 535 and the upper end of the second upper drive slider 5341. The two ends of the second drive connecting rod 5362 are pivotally connected to the eccentric drive rod 535 and the upper end of the second upper drive slider 5341, respectively.
[0097] It should be explained that the clamping block 52 includes a clamping pin clamping block 521 and a clamping block clamping block 522, which are respectively slidably mounted on the lower end of the first lower drive slider 5332.
[0098] Furthermore, a first driving cylinder 5371 is installed at the lower end of the first lower driving slider 5332, and a wedge-shaped stop 5372 is installed at the driving end of the first driving cylinder 5371. The first wedge-shaped stop 5372 is located above the clamping pin pressure block 521. A switching slider 5382 is slidably installed at the lower end of the second lower driving slider 5342. A second driving cylinder 5381 is fastened to the side of the switching slider 5382 at the lower end of the second lower driving slider 5342. The driving end of the second driving cylinder 5381 is connected to the switching slider 5382, and the switching slider 5382 is located above the clamping block pressure block 522.
[0099] In the process of the pressing block driving mechanism 53 driving the clamping pressing block 52 to move and perform clamping action in the sixth embodiment, the pressing block driving motor 531 drives the pressing block driving shaft 532 to rotate. The rotating pressing block driving shaft 532 drives the eccentric driving rod 535 to rotate eccentrically. The eccentrically rotating eccentric driving rod 535 drives the first driving slider group 533 to move up and down through the first driving connecting rod 5361. The eccentrically rotating eccentric driving rod 535 drives the second driving slider group 534 to move up and down through the second driving connecting rod 5362. The first driving slider group 533 and the second driving slider group 534 move synchronously. When it is necessary to drive the clamping block 522 downward and press the clamped block into place firmly, the second drive cylinder 5381 actuates and drives the switching slider 5382 to slide directly above the clamping block 522. The first drive cylinder 5371 actuates and causes the wedge-shaped stop 5372 to retract from directly above the clamping pin block 521. The second drive slider group 534 moves downward and drives the switching slider 5382 to move downward simultaneously. The downward-moving switching slider 5382 presses down on the clamping block 522. Since the wedge-shaped stop 5372 retracts from directly above the pin block, there is no gap above the clamping pin block 521. When it is necessary to drive the clamping pin block 521 downward and press the clamped block into place firmly, the second drive cylinder 5381 actuates and drives the switching slider 5382 to slide directly above the clamping pin block 522. When the delivered pin is pressed and tightened, the second drive cylinder 5381 is activated and drives the switching slider 5382 to move away from directly above the clamping block 522. The first drive cylinder 5371 is activated and causes the wedge block 5372 to move directly above the clamping pin 521. At this time, the wedge block 5372 blocks and limits the upper end of the clamping pin 521. When the first drive slider group 533 moves downward, the first drive slider group 533 drives the first drive cylinder 5371, the wedge block 5372, and the clamping pin 521 to move downward. Since the switching slider 5382 is deviated from directly above the clamping block 522, there is no gap above the clamping block 522.
[0100] It should be noted that, regarding the first drive slider group 533 of this embodiment, during use, the operator can adjust the height position of the first lower drive slider 5332 relative to the first upper drive slider 5331 as needed to adjust the height of the first lower drive slider 5332. By adjusting the height of the first lower drive slider 5332, the lower limit position of the first drive slider group 533 during movement can be adjusted, that is, it can be adaptively adjusted according to the clamping thickness requirements of the pin. Similarly, regarding the second drive slider group 534 of this embodiment, during use, the operator can adjust the height position of the second lower drive slider 5342 relative to the second upper drive slider 5341 as needed to adjust the height of the second lower drive slider 5342. By adjusting the height of the second lower drive slider 5342, the lower limit position of the switching slider 5382 during vertical movement can be adjusted, that is, it can be adaptively adjusted according to the clamping thickness requirements of the block.
[0101] It should be further noted that the first drive slider group 533 and the second drive slider group 534 in this embodiment six can adopt the following lifting and adjusting structure design. Specifically, the first drive slider group 533 and the second drive slider group 534 also include vertically arranged adjusting screws 539. The adjusting screw 539 in the first drive slider group 533 is screwed to the first upper drive slider 5331, and the lower end of the adjusting screw 539 in the first drive slider group 533 is connected to the first lower drive slider 5332. The adjusting screw 539 in the second drive slider group 534 is screwed to the second upper drive slider 5341, and the lower end of the adjusting screw 539 in the second drive slider group 534 is connected to the second lower drive slider 5342. During the adjustment process, the lifting and lowering adjustment of the first drive slider group 533 and the second drive slider group 534 can be achieved simply by rotating the corresponding adjusting screw 539.
[0102] Example 7, as Figures 1 to 5 As shown, the difference between this embodiment seven and embodiment one is that: the frame 1 is equipped with an automatic feeding mechanism 44 on the side of each clamping and pushing mechanism 4; during operation, the automatic feeding mechanism 44, which cooperates with the clamping and pushing mechanism 4 for installing blocks, feeds the blocks into the clamping and pushing mechanism 4, and the automatic feeding mechanism 44, which cooperates with the clamping and pushing mechanism 4 for installing pins, feeds the pins into the clamping and pushing mechanism 4.
[0103] Specifically, the automatic feeding mechanism 44 includes a feeding receiving block 441 mounted on the frame 1, the feeding receiving block 441 having a feeding groove 4411, and a feeding push rod 442 slidably mounted in the feeding groove 4411; a push rod drive cylinder 443 is mounted on the side of the feeding receiving block 441 on the frame 1, and the drive end of the push rod drive cylinder 443 is connected to the feeding push rod 442; a feeding vibrator is also mounted on the side of the feeding receiving block 441 on the frame 1. The discharge port of the feeding vibratory feeder 444 is connected to the feeding groove 4411 of the feeding receiving block 441. During operation, the feeding vibratory feeder 444 feeds the blocks or pins one by one into the feeding groove 4411 of the feeding receiving block 441. The push rod drive cylinder 443 drives the feeding push rod 442 to move so that the blocks or pins falling into the feeding groove 4411 are sent to the corresponding clamping and pushing mechanism 4 through the feeding push rod 442.
[0104] During the process of the clamping and pushing mechanism 4 installing the block or pin on the corresponding zipper centerline of the chain, the feeding vibrating plate 444 feeds out the block or pin in an orderly manner, and the orderly fed block or pin enters the feeding groove 4411 of the feeding receiving block 441 one by one; after the automatic gripper 43 of the clamping and pushing mechanism 4 moves to the clamping position and the fixed clamping block 431 and the movable clamping block 432 of the automatic gripper 43 open, the push rod drive cylinder 443 pushes the feeding push rod 442 to move. The moving feeding push rod 442 pushes the block or pin and makes the block or pin move towards the automatic gripper 43, and finally makes the block or pin enter between the fixed clamping block 431 and the movable clamping block 432 of the corresponding automatic gripper 43, so as to realize the automatic feeding action.

For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
