Description

Technical Field

[0001] This utility model relates to the technical field of zipper production and processing equipment, and in particular to a general-purpose zipper block pin machine. 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.

Detailed Implementation

[0065] The present invention will now be described in conjunction with specific embodiments.

[0066] Example 1, as Figure 1 and Figure 2 As shown, a general-purpose zipper block pinning machine includes a frame 1. The frame 1 is equipped with a first chain positioning component 21, a block pinning component, and a chain traction component 5 arranged sequentially from front to back along the chain conveying direction.

[0067] Among them, such as Figure 1 and Figure 2As shown, the frame 1 is equipped with a second chain positioning component 22 and a pinhole component 7 located above the second chain positioning component 22, between the block pin mounting component and the chain traction component 5.

[0068] Furthermore, such as Figures 3 to 6 As shown, the block pin mounting assembly includes two clamping and pushing mechanisms 4, one of which is used to install the block and the other is used to install the pin. 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.

[0069] Furthermore, such as Figures 1 to 4 As shown, the universal zipper block pin machine also includes a clamping assembly 6. When the block pin installation assembly installs the block or pin to the corresponding zipper centerline position of the chain, the automatic gripper 43 holds the block or pin in place, and the clamping assembly 6 moves and presses the movable clamping block 432 downward, so that the movable clamping block 432 presses the block or pin tightly against the corresponding zipper centerline position of the chain.

[0070] It should be explained that the first chain positioning component 21 and the second chain positioning component 22 in this embodiment are used to position the chain. The specific structure and working method of the chain positioning components have been disclosed in the prior art, and will not be repeated here. Also, the chain traction component 5 in this embodiment is used to traction the chain from front to back. The specific structure and working method of the chain traction component 5 have been disclosed in the prior art, and will not be repeated here.

[0071] In the process of installing blocks and pins using the block and pin installation assembly of this embodiment, the first chain positioning assembly 21 first positions the chain, and then one of the clamping and pushing mechanisms 4 clamps the block through the fixed clamping block 431 and the movable clamping block 432 of its automatic gripper 43, and the other clamping and pushing mechanism 4 clamps the pin through the fixed clamping block 431 and the 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 first chain positioning assembly 21, each pushing... The drive cylinder 41 pushes the corresponding pusher frame 42 forward, and each pusher frame 42 drives the corresponding automatic gripper 43 to move forward, so that the clamped block and pin are inserted into the corresponding zipper center line of the chain belt. After the block and pin are pushed forward into place, the clamping assembly 6 is activated. The automatic gripper 43 holds the block or pin in place, and the clamping assembly 6 is activated and pushes the movable clamping block 432 downward, so that the movable clamping block 432 presses the block or pin tightly against the corresponding zipper center line of the chain belt.

[0072] It should be noted that in this embodiment, the block or pin clamps the corresponding zipper centerline part of the chain by pressing the movable clamping block 432. 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 edge clamping method of the block and pin in the prior art, this embodiment has better stability and reliability.

[0073] In the operation of the general-purpose zipper block pin machine of this embodiment, after the first chain positioning component 21, the block pin installation component, and the clamping component 6 cooperate to complete the block pin installation, the chain with the block pin installed is then positioned by the second chain positioning component 22. Then, the eyeletting component 7 performs eyeletting to reinforce the back of the block and pin. It should be explained that when the chain passes through the first chain positioning component 21 with the front side facing up and the block pin is installed, the operator can flip the chain and feed it so that the back side faces up as it passes through the second chain positioning component 22, allowing the eyeletting component 7 to make eyelets on the back of the block and pin. When the chain passes through the first chain positioning component 21 with the back side facing up and the block pin is installed, the operator can pass the chain directly through the second chain positioning component 22 without flipping it, allowing the eyeletting component 7 to make eyelets on the back of the block and pin. Therefore, the universal zipper block pin machine of this embodiment can be used for the installation of block pins for both left-side and right-side zippers, making it highly versatile.

[0074] It should be further emphasized that, since the universal zipper block pin machine of this embodiment does not perform pin hole pressing at the installation position of the block pin, but rather achieves the pressing of the block and pin by pressing the movable clamping block 432 of the automatic gripper 43, with the clamping and pushing mechanism 4 remaining unchanged, only the conveying direction of the chain belt needs to be changed (either front-facing or back-facing conveying) to achieve universal installation of block pins for left-side zipper insertion and right-side zipper insertion. For example, when front-facing conveying is used to install block pins for left-side zipper insertion, simply adjusting to back-facing conveying will achieve block pin installation for right-side zipper insertion. Therefore, the universal zipper block pin machine of this embodiment can achieve universal installation for both left-side and right-side zipper insertion, meaning that zipper manufacturers only need one machine to simultaneously meet the processing needs of left-side and right-side zipper insertion, thereby reducing the purchase cost of zipper production equipment.

[0075] In summary, the general-purpose zipper block pin machine of this embodiment has the advantages of novel structural design, good stability and reliability, and strong versatility. It can also realize the ability to insert nylon zippers or metal zippers from the left or right and pass them through in both directions.

[0076] Example 2, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 11 , Figure 12 As shown, the difference between this embodiment two and embodiment one is that the clamping assembly 6 includes a clamping mounting base 61 mounted on the frame 1. The clamping mounting base 61 is equipped with a clamping pressure block 62 and a pressure block driving mechanism 63 for driving the clamping pressure block 62 to move up and down. During operation, when the block and pin mounting assembly installs the block or pin to the corresponding zipper centerline of the chain, the automatic gripper 43 holds the block or pin in place, and the pressure block driving mechanism 63 drives the clamping pressure block 62 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.

[0077] Specifically, the pressing block drive mechanism 63 includes a pressing block drive motor 631 and a pressing block drive shaft 632 mounted on the clamp mounting base 61. The power output shaft of the pressing block drive motor 631 is drivenly connected to the pressing block drive shaft 632.

[0078] The pressing block driving mechanism 63 further includes a first driving slider group 633 and a second driving slider group 634 that are slidably mounted on the clamp mounting base 61. The first driving slider group 633 includes a first upper driving slider 6331 and a first lower driving slider 6332 that is adjustablely mounted on the lower end of the first upper driving slider 6331. The second driving slider group 634 includes a second upper driving slider 6341 and a second lower driving slider 6342 that is adjustablely mounted on the lower end of the second upper driving slider 6341.

[0079] Furthermore, an eccentric drive rod 635 is installed at the end of the pressure block drive shaft 632. A first drive connecting rod 6361 is installed between the eccentric drive rod 635 and the upper end of the first upper drive slider 6331. The two ends of the first drive connecting rod 6361 are pivotally connected to the eccentric drive rod 635 and the upper end of the first upper drive slider 6331, respectively. A second drive connecting rod 6362 is installed between the eccentric drive rod 635 and the upper end of the second upper drive slider 6341. The two ends of the second drive connecting rod 6362 are pivotally connected to the eccentric drive rod 635 and the upper end of the second upper drive slider 6341, respectively.

[0080] It should be explained that the clamping block 62 includes a clamping pin clamping block 621 and a clamping block clamping block 622, which are respectively slidably mounted on the lower end of the first lower drive slider 6332.

[0081] Furthermore, a first driving cylinder 6371 is installed at the lower end of the first lower driving slider 6332, and a wedge-shaped stop 6372 is installed at the driving end of the first driving cylinder 6371. The first wedge-shaped stop 6372 is located above the clamping pin pressure block 621. A switching slider 6382 is slidably installed at the lower end of the second lower driving slider 6342. A second driving cylinder 6381 is fastened to the side of the switching slider 6382 at the lower end of the second lower driving slider 6342. The driving end of the second driving cylinder 6381 is connected to the switching slider 6382, and the switching slider 6382 is located above the clamping block pressure block 622.

[0082] In the process of the pressing block driving mechanism 63 driving the clamping pressing block 62 to move and perform clamping action in the second embodiment, the pressing block driving motor 631 drives the pressing block driving shaft 632 to rotate. The rotating pressing block driving shaft 632 drives the eccentric driving rod 635 to rotate eccentrically. The eccentrically rotating eccentric driving rod 635 drives the first driving slider group 633 to move up and down through the first driving connecting rod 6361. The eccentrically rotating eccentric driving rod 635 drives the second driving slider group 634 to move up and down through the second driving connecting rod 6362. The first driving slider group 633 and the second driving slider group 634 move synchronously. When it is necessary to drive the clamping block 622 downward and press the clamped block into place firmly, the second drive cylinder 6381 actuates and drives the switching slider 6382 to slide directly above the clamping block 622. The first drive cylinder 6371 actuates and causes the wedge-shaped stop 6372 to retract from directly above the clamping pin block 621. The second drive slider group 634 moves downward and drives the switching slider 6382 to move downward simultaneously. The downward-moving switching slider 6382 presses down on the clamping block 622. Since the wedge-shaped stop 6372 retracts from directly above the pin block, there is no gap above the clamping pin block 621. When it is necessary to drive the clamping pin block 621 downward and press the clamped block into place firmly, the second drive cylinder 6381 actuates and drives the switching slider 6382 to slide directly above the clamping pin block 622. When the delivered pin is pressed and tightened, the second drive cylinder 6381 actuates and drives the switching slider 6382 to retract from directly above the clamping block 622. The first drive cylinder 6371 actuates and causes the wedge block 6372 to move directly above the clamping pin 621. At this time, the wedge block 6372 blocks and limits the upper end of the clamping pin 621. When the first drive slider group 633 moves downward, the first drive slider group 633 drives the first drive cylinder 6371, the wedge block 6372, and the clamping pin 621 to move downward. Since the switching slider 6382 is deviated from directly above the clamping block 622, there is no gap above the clamping block 622.

[0083] It should be noted that, regarding the first drive slider group 633 of this embodiment, during use, the operator can adjust the height position of the first lower drive slider 6332 relative to the first upper drive slider 6331 as needed to adjust the height of the first lower drive slider 6332. By adjusting the height of the first lower drive slider 6332, the lower limit position of the first drive slider group 633 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 634 of this embodiment, during use, the operator can adjust the height position of the second lower drive slider 6342 relative to the second upper drive slider 6341 as needed to adjust the height of the second lower drive slider 6342. By adjusting the height of the second lower drive slider 6342, the lower limit position of the switching slider 6382 during vertical movement can be adjusted, that is, it can be adaptively adjusted according to the clamping thickness requirements of the block.

[0084] It should be further noted that the first drive slider group 633 and the second drive slider group 634 in this embodiment can adopt the following lifting and adjusting structure design. Specifically, the first drive slider group 633 and the second drive slider group 634 also include vertically arranged adjusting screws 639. The adjusting screw 639 in the first drive slider group 633 is screwed to the first upper drive slider 6331, and the lower end of the adjusting screw 639 in the first drive slider group 633 is connected to the first lower drive slider 6332. The adjusting screw 639 in the second drive slider group 634 is screwed to the second upper drive slider 6341, and the lower end of the adjusting screw 639 in the second drive slider group 634 is connected to the second lower drive slider 6342. During the adjustment process, the lifting and lowering adjustment of the first drive slider group 633 and the second drive slider group 634 can be achieved simply by rotating the corresponding adjusting screw 639.

[0085] Example 3, as Figures 7 to 9 , Figure 20 As shown, the difference between this embodiment 3 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.

[0086] 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.

[0087] During the action of the clamping assembly 6 and the downward movement of the movable clamping block 432, the downward-moving clamping block 62 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.

[0088] Example 4, as Figure 10 As 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 driving 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.

[0089] 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 6 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 6 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.

[0090] 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.

[0091] Example 5, such as Figures 7 to 9 , Figure 20 As shown, the difference between this fifth embodiment and the first embodiment 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.

[0092] 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 five can enable the fixed clamping block 431 and movable clamping block 432 to stably and accurately clamp the block or the pin.

[0093] 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.

[0094] It should be noted that when the clamping assembly 6 is activated and the block and pin are pressed and fixed to the corresponding zipper centerline of the chain, the clamping block 62 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 arm 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.

[0095] Example 6, as Figures 1 to 6 As shown, the difference between this sixth embodiment and the first embodiment is that the frame 1 is equipped with an automatic feeding mechanism 44 on the side of each clamping and pushing mechanism 4.

[0096] 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 vibration device 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.

[0097] During the process of the clamping and pushing mechanism 4 installing the block or pin on the edge of the webbing on the corresponding side of the chain belt, the feeding vibrating plate 444 sends out the block or pin in an orderly manner, and the block or pin sent out in an orderly manner 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 side, 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 to realize the automatic feeding action.

[0098] Example 7, as Figures 13 to 18 , Figure 21 As shown, the difference between this embodiment seven and embodiment one is that: the needle hole assembly 7 includes a needle hole mounting base 71 installed on the frame 1, and a needle hole lifting drive cylinder 721 that moves up and down is installed at the upper end of the needle hole mounting base 71; a needle hole lifting slider 722 is installed on the needle hole mounting base 71 below the needle hole lifting drive cylinder 721, and the drive end of the needle hole lifting cylinder is connected to the upper end of the needle hole lifting slider 722.

[0099] The needle insertion mounting base 71 is horizontally slidably equipped with a lower switching slider 731 located below the needle insertion lifting slider 722. The needle insertion mounting base 71 is equipped with a lower switching drive cylinder 732 corresponding to the lower switching slider 731. The drive end of the lower switching drive cylinder 732 is connected to the lower switching slider 731. The lower switching slider 731 is equipped with a needle insertion mounting base 733. The needle insertion mounting base 733 is equipped with four movable needles 734 arranged in a rectangular shape. The four movable needles 734 are, in order, the left front needle, the left rear needle, the right front needle, and the right rear needle. The left front needle and the left rear needle are aligned front to back and spaced apart. The right front needle and the right rear needle are aligned front to back and spaced apart.

[0100] In addition, the needle hole lifting slider 722 is horizontally slidable to the left and right and is equipped with an upper switching slider 741 located above the lower switching slider 731. The needle hole mounting base 71 is equipped with an upper switching drive cylinder 742 corresponding to the upper switching slider 741. The drive end of the upper switching drive cylinder 742 is connected to the upper switching slider 741. The upper switching slider 741 is located above the left rear end needle and the right rear end needle, and a downward-opening slider clearance groove 7411 is opened in the middle of the lower surface of the upper switching slider 741.

[0101] Furthermore, the injection hole lifting slider 722 is equipped with slider protrusions 7221 located above the left front injection hole and the right front injection hole.

[0102] The injection site component 7 of this embodiment will be described in detail below with reference to the specific action process;

[0103] 1. When the pin position of the chain entering the second chain positioning component 22 is on the left and the block position is on the right, it is necessary to drill one pinhole on the left and two pinholes on the right. The lower switching drive cylinder 732 drives the lower switching slider 731 to move horizontally, causing each movable pinhole 734 to move to the corresponding position. The left front pinhole and the right front pinhole face the slider protrusion 7221 of the pinhole lifting slider 722. The upper switching drive cylinder 742 drives the upper switching slider 741 to move, causing the left rear pinhole to face the slider clearance groove 7411 of the upper switching slider 741 and the right rear pinhole to deviate from the upper switching slider 734. 41 slider clearance groove 7411; after the upper switching slider 741 and the lower switching slider 731 move into place, the needle hole lifting drive cylinder 721 is activated and drives the needle hole lifting drive slider to move down. The needle hole lifting slider 722 drives the upper switching drive cylinder 742 and the upper switching slider 741 to move down synchronously. During this process, the slider protrusion 7221 of the needle hole lifting slider 722 simultaneously presses down on the left front needle and the right front needle, and the upper switching slider 741 presses down on the right rear needle. The left front needle makes a needle hole for the pin, and the right front needle and the right rear needle make a needle hole for the block.

[0104] 2. When the pin position of the chain entering the second chain positioning component 22 is on the right and the block position is on the left, two pinholes need to be drilled on the left and one pinhole on the right. The lower switching drive cylinder 732 drives the lower switching slider 731 to move horizontally, causing each movable pinhole 734 to move to the corresponding position. The left front pinhole and the right front pinhole are aligned with the slider protrusion 7221 of the pinhole lifting slider 722. The upper switching drive cylinder 742 drives the upper switching slider 741 to move, causing the left rear pinhole to deviate from the slider clearance groove 7411 of the upper switching slider 741 and the right rear pinhole to align with the upper switching slider 741. 1. Slider clearance groove 7411; After the upper switching slider 741 and the lower switching slider 731 move into place, the needle hole lifting drive cylinder 721 is activated and drives the needle hole lifting drive slider to move down. The needle hole lifting slider 722 drives the upper switching drive cylinder 742 and the upper switching slider 741 to move down synchronously. During this process, the slider protrusion 7221 of the needle hole lifting slider 722 simultaneously presses down on the left front needle and the right front needle, while the upper switching slider 741 presses down on the left rear needle. The right front needle drills a needle hole for the pin, and the left front needle and the left rear needle drill a needle hole for the block.

[0105] It should be emphasized that the eyelet assembly 7 of this embodiment 7 can make eyelets on the chain belt in different conveying directions, and has strong adaptability and versatility.

[0106] Example 8, as Figure 1 , Figure 3 , Figure 13 , Figure 14 as well as Figure 19 As shown, the difference between this embodiment eight and embodiment one is that: the frame 1 is respectively equipped with lifting adjustment seats 3 corresponding to the first chain positioning component 21 and the second chain positioning component 22, and the first chain positioning component 21 and the first chain positioning component 22 are respectively installed on the corresponding lifting adjustment seats 3.

[0107] Specifically, the lifting adjustment seat 3 includes a fixed seat 31 screwed and fastened to the frame 1, and a movable seat 32 is slidably mounted on the fixed seat 31. The first chain positioning component 21 and the second chain positioning component 22 are respectively mounted on the upper end of the corresponding movable seat 32.

[0108] In addition, a lifting adjustment mechanism 33 is installed between the movable seat 32 and the fixed seat 31. The lifting adjustment mechanism 33 includes a lifting adjustment screw 331 installed on the fixed seat 31 and arranged vertically. The lifting adjustment screw 331 is located below the movable seat 32, and the lower end of the movable seat 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 seat 32. The lifting adjustment screw 331 is screwed with a support nut 332, and the movable seat 32 abuts against and supports the upper surface of the support nut 332. The fixed seat 31 has a vertically extending lifting guide groove 333, and the movable seat 32 is provided with a lifting guide rail 334 that is slidably installed in the lifting guide groove 333.

[0109] 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 universal zipper block and pin machine of this embodiment seven can adaptively adjust the height of the first chain belt positioning component 21 so that the webbing of the chain belt is aligned with the clamping and pushing mechanism 4. That is, this embodiment eight can be applied to the block and pin installation operation of metal zippers and nylon zippers, and has strong adaptability and versatility.

[0110] Furthermore, since the needle hole punching stroke of the needle hole punching component 7 is fixed, the universal zipper block pin machine of this embodiment eight can adaptively adjust the height of the second chain positioning component 22 so that the chain can be adaptively adjusted to the needle hole punching height position. That is, this embodiment eight can be applied to the needle hole punching operation of metal zippers and nylon zippers, and has strong adaptability and versatility.

[0111] It should be noted that during the adaptive adjustment of the height of the first chain positioning component 21 and the second chain positioning component 22, 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 achieve adaptive adjustment of the height position of the first chain positioning component 21 or the second chain positioning component 22.

[0112] The above description is only a preferred embodiment of this utility model. 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.
