Description

Technical Field

[0001] The utility model relates to the technical field of zipper manufacturing, in particular to a metal butterfly-shaped movable top stop machine. Background Art

[0002] A zipper's top stop is a fixed component of the zipper tape. It secures the ends of the zipper tape, preventing the slider from falling off and ensuring the zipper remains in the correct position when closed. The top stop not only provides structural stability but also prevents the zipper from opening during use.

[0003] Among them, a metal butterfly-shaped top stop (for example, a copper butterfly code) includes a butterfly-shaped body and a buckle foot set on the body. The metal butterfly-shaped top stop has become a highlight among zipper top stops due to its unique design. Its metal material gives it excellent strength and toughness, making it widely used in the zipper manufacturing field.

[0004] In order to facilitate the installation of the metal butterfly-shaped top stop on the zipper tape, technicians have developed a related top stop machine, including a base, a top stop mold set on the base, and a cylinder. The top stop mold is provided with a mounting slot for the metal butterfly-shaped top stop to be placed, and part of the buckle legs extend outward from the mounting slot. The end of the cylinder is provided with a pressure block, and the cylinder drives the pressure block to move in the direction of approaching or moving away from the mounting slot. When installing the metal butterfly-shaped top stop on the zipper tape, the operator places the metal butterfly-shaped top stop in the mounting slot so that part of the buckle legs extend outward from the mounting slot. The operator pinches the zipper tape into a Y shape (fixing the two sides of the cloth tape at one end and separating the two sides of the cloth tape at the other end) to adapt to the shape of the metal butterfly-shaped top stop. Then, the branches of the Y-shaped zipper tape are aligned with the metal butterfly top stop. The cylinder drives the pressure block to pass the buckle legs through and fasten them to the zipper tape.

[0005] However, using the top stop machine in the prior art requires an operator to place the top stop in the installation slot, pinch the zipper tape into a Y shape, and install the top stop by punching it one by one, which makes the installation efficiency low. Utility Model Content

[0006] In order to improve the problem that an operator is required to pinch a zipper tape into a Y-shape, the utility model provides a metal butterfly-shaped movable top stop machine which can pinch a zipper tape into a Y-shape and has high installation efficiency.

[0007] The utility model provides a metal butterfly-shaped movable top stop machine, which adopts the following technical solutions:

[0008] A metal butterfly-shaped movable top stop machine comprises a frame, wherein the frame is provided with a feeding mechanism and a mounting mechanism; the mounting mechanism comprises a mounting frame provided on the frame, a belt pressing assembly provided on the mounting frame, and an assembly assembly;

[0009] The belt pressing assembly includes a lower mold base, an upper mold base and a forked stop rod slidably arranged on the lower mold base, the lower mold base is provided with a chain belt base and an outer lower membrane, the outer lower membrane is located on one side of the chain belt base, a cloth pushing slider is slidably provided on the outer lower membrane, the upper mold base is slidably provided with a cloth pressure plate, and the cloth pressure plate slides in the direction approaching or away from the chain belt base, the forked stop rod is passed through the lower mold base, and a rod gap for the forked stop rod to pass through is formed between the outer lower membrane and the chain belt base, the forked stop rod slides and cooperates with the lower mold base in the direction of extending out or extending into the rod gap, and the cloth pushing slider is used to push the cloth belts on both sides of the zipper belt in the direction approaching each other.

[0010] With the above technical solution, during loading, the top stop is fed into the assembly assembly via the loading mechanism. When installing the zipper tape, the zipper tape is placed on the tape base, the end of the zipper tape is placed on the outer lower membrane, and the two side tapes of the zipper tape are placed on the tape base, so that the two side tapes face each other along the width of the tape base. Furthermore, one side of the zipper tape end is inserted into the first and second tape gaps of a cloth push slider, so that the two side tapes of the zipper tape end are located within the two cloth push sliders.

[0011] When the zipper tape is installed, the cloth pressing plate is driven to move in a direction close to or away from the chain base, so that the cloth pressing plate abuts against the chain base. At the same time, the zipper tape on the chain base is pressed and fixed, thereby preventing the zipper tape on the chain base from moving. Then, the forked baffle is driven to slide along the length direction of the support portion, so that one end of the forked baffle extends through the rod gap. At this time, the two side tapes in the zipper tape are located on both sides of the forked baffle. By driving the cloth pushing slider to slide in a direction toward each other, the two side tapes in the zipper tape are pushed in a direction close to each other. Through the resistance of the forked baffle, the two side tapes on the outer lower membrane are gradually tightened and overlapped along the edge of the forked baffle, thereby driving the zipper tape into a Y shape. Finally, the assembly component is driven to install the top stop on the zipper tape.

[0049] The following is a combination of the appended examples of the present invention Figures 1 to 12 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0050] A metal butterfly-shaped movable top stop machine, refer to Figure 1 The invention comprises a square frame 1, on which a feeding mechanism and an installation mechanism are provided. The feeding mechanism is used to arrange the scattered top stops 18 and transport them one by one to the installation mechanism, and the installation mechanism is used to install the top stops 18 on the zipper tape.

[0051] It should be noted that, referring to Figure 2 In this embodiment, the top stop 18 is a copper butterfly code. The top stop 18 includes a butterfly-shaped body and four buckle feet. The four buckle feet are respectively located at the four corners of the body. The top stop 18 can be installed by passing the buckle feet through the cloth belt and driving the buckle feet to bend.

[0052] Specifically, refer to Figure 3 The loading mechanism includes a vibrating plate 5 for arranging the scattered top stops 18 into rows and transporting them out, and a feeding assembly for delivering the top stops 18 one by one to the installation mechanism. The vibrating plate 5 is a relatively mature technology in the prior art and will not be described in detail here. One end of the vibrating plate 5 serves as the discharge end. During loading, the scattered top stops 18 are placed into the vibrating plate 5, which then arranges them into rows and transports them out from the discharge end. The feeding assembly then delivers the top stops 18 one by one to the installation mechanism, where they are then installed.

[0053] Reference Figure 4 and Figure 5 The feeding assembly includes a feeding main seat 6 connected to the vibration plate 5, a main seat pressure plate 7 arranged on the feeding main seat 6, and an upper stop pressure plate 11 arranged on the main seat pressure plate 7.

[0054] Continue to refer to Figure 4 and Figure 5 The main feed seat 6 is in the shape of an elongated block, and one long side of the main feed seat 6 is connected to the discharge end of the vibration plate 5. A feeding trough 8 is provided on the main feed seat 6. The feeding trough 8 is a long trough and is distributed along the width direction of the main feed seat 6. The shape of the feeding trough 8 allows the upper stop 18 to move along the length direction of the feeding trough 8. The feeding trough 8 passes through the top side of the main feed seat 6, and one end of the feeding trough 8 is connected to the discharge end of the vibration plate 5, so that the upper stop 18 transported out of the discharge end of the vibration plate 5 enters the feeding trough 8, and through the vibration of the vibration plate 5, the upper stop 18 in the feeding trough 8 moves along the length direction of the feeding trough 8. The main seat pressure plate 7 is in the shape of a long plate. The main seat pressure plate 7 is distributed along the length direction perpendicular to the feed trough 8. The main seat pressure plate 7 is arranged on the top side of the feed main seat 6. The main seat pressure plate 7 is fixed to the feed main seat 6 by bolts, and one side of the main seat pressure plate 7 closes the top side of the feed trough 8, thereby preventing the upper stop 18 from falling out of the feed trough 8 during movement.

[0055] Reference Figure 4 and Figure 5The main feed seat 6 is also provided with a push chute 9, which is also a long trough and is distributed along the length of the main feed seat 6. The push chute 9 runs through both ends of the main feed seat 6 and is connected to the end of the feed trough 8 away from the vibrating plate 5. In addition, the cross-section of the push chute 9 is square and just allows one upper stop 18 to enter the push chute 9. A push slider 10 is slidably provided in the push chute 9. The push slider 10 is in the shape of an elongated block and is distributed along the length of the push chute 9. The push slider 10 slides along the length of the push chute 9 and fits into the push chute 9. The mounting mechanism is located at one end of the main feed seat 6. When the upper stop 18 in the feed trough 8 moves along the length direction of the feed trough 8, an upper stop 18 at the end of the feed trough 8 enters the pushing chute 9. By driving the pushing slider 10 to move along the length direction of the pushing chute 9, an upper stop 18 located in the pushing chute 9 can be pushed to the installation mechanism.

[0056] Reference Figure 4 and Figure 5 A first cylinder 19 is provided at one end of the feeding main seat 6 away from the mounting mechanism. The first cylinder 19 is used to drive the push slide 10 to slide along the length direction of the push chute 9. The driving end of the first cylinder 19 is connected to one end of the push slide 10. Therefore, when feeding, the vibration of the vibrating plate 5 causes the top stop 18 in the feeding trough 8 to move along the length direction of the feeding trough 8, so that a top stop 18 at the end of the feeding trough 8 enters the pushing chute 9. The first cylinder 19 drives the push slide 10 to move along the length direction of the pushing chute 9, pushing a top stop 18 located in the pushing chute 9 to the mounting mechanism.

[0057] In addition, continue to refer to Figure 4 and Figure 5 In order to prevent the upper stop 18 of the pushing slider 10 from falling out of the pushing chute 9 during the pushing process, the pushing slider 10 is integrally formed with a stopper 14. The stopper 14 is located at the end of the pushing slider 10 away from the first cylinder 19. The stopper 14 is close to the top side of the pushing slider 10. When an upper stop 18 at the end of the feed trough 8 enters the pushing chute 9, the stopper 14 is located on the top side of the upper stop 18, thereby preventing the upper stop 18 from falling out of the pushing chute 9 during the sliding process of the pushing slider 10 through the limiting of the stopper 14.

[0058] Continue to refer to Figure 4 and Figure 5, a through opening 20 is provided on the main seat pressure plate 7. The through opening 20 is distributed along the height direction of the main seat pressure plate 7 and passes through the upper and lower surfaces of the main seat pressure plate 7, and the through opening 20 is connected to the feed trough 8. The upper pressure stop plate 11 is in the shape of an L-shaped block. The upper pressure stop plate 11 includes two ends, and the first end of the upper pressure stop plate 11 extends into the through opening 20. When the upper pressure stop plate 11 is driven to move along the length direction of the through opening 20, the first end of the upper pressure stop plate 11 is driven to extend into or out of the feed trough 8. When the upper pressure stop plate 11 extends into the feed trough 8, the upper stop 18 closest to the push chute 9 is fixed, thereby stopping the upper stop 18 in the feed trough 8 from moving forward. When the upper pressure stop plate 11 extends out of the feed trough 8, the upper stop 18 in the feed trough 8 continues to move forward due to the vibration of the vibration plate 5.

[0059] Reference Figure 3 and Figure 5 A pressure plate frame 21 is also provided on the main seat pressure plate 7, and a second cylinder 22 is provided on the pressure plate frame 21 for driving the upper pressure stop plate 11 to slide along the length direction of the through opening 20. The second cylinder 22 is a punch needle positioning cylinder, and the driving end of the second cylinder 22 is connected to the upper pressure stop plate 11, so that the upper pressure stop plate 11 is driven to move along the length direction of the through opening 20 by the second cylinder 22, so that the upper pressure stop plate 11 extends into or extends out of the feed trough 8.

[0060] During feeding, the scattered top stops 18 are arranged into rows by the vibration plate 5 and transported to the feeding trough 8. The vibration of the vibration plate 5 causes the top stops 18 in the feeding trough 8 to move along the length direction of the feeding trough 8 and enter the pushing chute 9 through a top stop 18 at the end of the feeding trough 8. At this time, the second cylinder 22 drives the upper pressure plate 11 to move along the length direction of the through-port 20, so that the upper pressure plate 11 extends into the feeding trough 8 and fixes a top stop 18 closest to the pushing chute 9, thereby stopping the top stop 18 in the feeding trough 8 from moving forward and ensuring the stability of subsequent feeding. The first cylinder 19 drives the pushing slide 10 to move along the length direction of the pushing chute 9, so that a top stop 18 located in the pushing chute 9 can be pushed to the installation mechanism.

[0061] Specifically, refer to Figure 6 and Figure 7 The mounting mechanism includes a mounting frame 2 mounted on a frame 1, a belt pressing assembly 3 mounted on the mounting frame 2, and an assembly assembly 4. The belt pressing assembly 3 is used to drive the zipper tape into a Y-shape, and the assembly assembly 4 is used to attach the top stop 18 to the branches of the zipper tape Y-shape. The mounting frame 2 is an inverted L-shaped block, with one end fixedly connected to the frame 1.

[0062] Reference Figure 6 and Figure 8 The belt pressing assembly 3 includes a lower die base 31 , an upper die base 32 and a forked blocking rod 33 slidably arranged on the lower die base 31 .

[0063] Reference Figure 6 and Figure 8 The lower die base 31 includes a connecting portion 311 and a supporting portion 312. The connecting portion 311 is connected to the mounting frame 2. The supporting portion 312 is in the form of a rectangular block. The supporting portion 312 is distributed along the height direction of the frame 1. A chain base 34 is provided on the top side of the supporting portion 312. The chain base 34 is in the form of a rectangular plate. The chain base 34 is distributed along the length direction of the push slider 10. A chain tooth groove 23 is provided on the chain base 34. The chain tooth groove 23 is distributed along the length direction of the chain base 34 and passes through both ends of the chain base 34. There are two chain tooth grooves 23, and the two chain tooth grooves 23 are spaced apart along the width direction of the chain base 34. When in use, by placing the zipper tape on the chain base 34 and placing the chain teeth of the cloth tapes on both sides in the chain tooth grooves 23, the cloth tapes on both sides of the chain base 34 can be limited.

[0064] Reference Figure 6 and Figure 8 The support portion 312 is also provided with an outer lower membrane 35. The outer lower membrane 35 is in the shape of an elongated block and extends along the width of the chain base 34. The outer lower membrane 35 is located at one end of the chain base 34 and is close to the feed assembly. The outer lower membrane 35 has a first chute 351 extending along its length and extending through the top and ends of the outer lower membrane 35. The outer lower membrane 35 also has a second chute 352 extending along its length and extending through the top and ends of the outer lower membrane 35. The second chute 352 and the first chute 351 are aligned along the width of the outer lower membrane 35, and the first chute 351 is close to the chain base 34.

[0065] Reference Figure 8 and Figure 9 A cloth-pushing slider 36 is slidably provided on the outer lower membrane 35. The cloth-pushing slider 36 includes a driving block 361, a first limiting block 362 and a second limiting block 363 provided on the driving block 361. The driving block 361 is provided at one end of the outer lower membrane 35. The first limiting block 362 and the second limiting block 363 are both located on the side of the driving block 361 facing the outer lower membrane 35. Figure 10The first limiting block 362 forms a first cloth-tape gap 12 for the cloth tape to pass through, and the first limiting block 362 slidably cooperates with the first chute 351. The second limiting block 363 forms a second cloth-tape gap 13 for the cloth tape to pass through, and the second limiting block 363 slidably cooperates with the second chute 352. The driving block 361 slides along the length direction of the outer lower membrane 35, causing the first limiting block 362 to slide along the length direction of the first chute 351, and the second limiting block 363 to slide along the length direction of the second chute 352. Two cloth-pushing sliders 36 are provided, and the two cloth-pushing sliders 36 are opposed to each other along the length direction of the outer lower membrane 35.

[0066] When installing the zipper tape, place the end of the zipper tape on the tape base 34, the end of the zipper tape on the outer lower membrane 35, and the two side tapes of the zipper tape on the tape base 34, wherein the fastener elements on the tape are respectively located in the two fastener element grooves 23, so that the two side tapes are opposite each other along the width direction of the tape base 34. Furthermore, extend one side of the zipper tape end into the first tape gap 12 and the second tape gap 13 of a cloth pushing slider 36, so that the two side tapes of the zipper tape end are respectively located in the two cloth pushing sliders 36.

[0067] Reference Figure 6 and Figure 8 , the upper mold base 32 is located on the top side of the lower mold base 31. The upper mold base 32 is slidably provided with a cloth pressing plate 37. When the cloth pressing plate 37 is driven to move along the height direction of the frame 1, the cloth pressing plate 37 abuts against or moves away from the chain base 34. The upper mold base 32 is provided with a third cylinder 24 for driving the pressing plate to move along the height direction of the frame 1. The driving end of the third cylinder 24 is connected to the cloth pressing plate 37. When the zipper tape is installed, the cloth pressing plate 37 is driven by the third cylinder 24 to move along the height direction of the frame 1, so that the cloth pressing plate 37 abuts against the chain base 34. At the same time, the zipper tape on the chain base 34 is pressed and fixed, thereby preventing the zipper tape on the chain base 34 from moving.

[0068] Reference Figure 8 and Figure 10The forked barrier rod 33 is disposed through the support portion 312. The forked barrier rod 33 is a long rod and extends along the length of the support portion 312. The forked barrier rod 33 is located between the two chain tooth grooves 23. The forked barrier rod 33 slides along the length of the support portion 312 and fits within the support portion 312. A rod gap 38 is formed between the outer lower membrane 35 and the chain belt base 34 for the forked barrier rod 33 to pass through. By driving the forked barrier rod 33 to slide along the length of the support portion 312, one end of the forked barrier rod 33 can be extended into or out of the rod gap 38. A fourth cylinder 25 is provided at the end of the support portion 312 facing away from the outer lower membrane 35. The fourth cylinder 25 is used to drive the forked barrier rod 33 to move along the length of the support portion 312. The driving end of the fourth cylinder 25 is connected to the forked barrier rod 33. Thus, the fourth cylinder 25 drives the forked blocking rod 33 to slide along the length direction of the support portion 312 , so that one end of the forked blocking rod 33 can be extended into or out of the rod gap 38 .

[0069] Reference Figure 8 and Figure 9 The support portion 312 is provided with a fifth cylinder 26, and the driving end of the fifth cylinder 26 is connected to the driving block 361. Thus, the fifth cylinder 26 drives the block 361 to slide along the length direction of the outer lower membrane 35, causing the first limit block 362 to slide along the length direction of the first chute 351, and the second limit block 363 to slide along the length direction of the second chute 352. That is, the cloth-pushing slider 36 can be driven to slide as a whole by the fifth cylinder 26. Two fifth cylinders 26 are provided corresponding to the number of cloth-pushing sliders 36. The two fifth cylinders 26 are connected to the driving blocks 361 of the two cloth-pushing sliders 36 in a one-to-one correspondence. Since the two cloth-pushing sliders 36 are opposite to each other along the length direction of the outer lower membrane 35, the two fifth cylinders 26 respectively drive the two cloth-pushing sliders 36 to slide in directions toward or away from each other. When the two fifth air cylinders 26 respectively drive the two cloth pushing sliders 36 to move in directions toward each other, the first limit block 362 and the second limit block 363 on one cloth pushing slider 36 push one side of the cloth tape of the zipper tape along the length direction of the outer lower membrane 35, and the two cloth pushing sliders 36 respectively push the two sides of the cloth tape of the zipper tape in the direction close to each other.

[0070] When the zipper tape is installed, the third cylinder 24 drives the cloth pressing plate 37 to move in the height direction of the frame 1, so that the cloth pressing plate 37 abuts against the chain base 34, and at the same time, presses and fixes the zipper tape on the chain base 34, thereby preventing the zipper tape on the chain base 34 from moving. When the cloth pressing plate 37 presses and fixes the zipper tape on the chain base 34, the fourth cylinder 25 drives the forked blocking rod 33 to slide along the length direction of the support portion 312, so that one end of the forked blocking rod 33 extends through the rod gap 38. At this time, the two side strips of the zipper tape are located on both sides of the forked blocking rod 33. The two fifth cylinders 26 are used to drive the two cloth-pushing sliders 36 to slide in directions toward each other, so that the two cloth-pushing sliders 36 push the two side tapes of the zipper tape in directions close to each other, and the forked baffle 33 is used to resist the two side tapes on the outer lower membrane 35, so that the two side tapes are gradually tightened and overlapped along the edge of the forked baffle 33, thereby driving the zipper tape into a Y shape. Then, the top stop 18 is installed on the zipper tape through the assembly component 4 to complete the installation of the top stop 18.

[0071] Specifically, refer to Figure 5 and Figure 11 The assembly component 4 includes a positioning plate 41 provided on the mounting frame 2 and a die base 42 slidably provided on the positioning plate 41. The positioning plate 41 is U-shaped, close to the pusher slider 10, and the opening of the positioning plate 41 faces the pusher slider 10. The die base 42 is long and distributed along the length direction of the pusher slider 10. The shape of the die base 42 is adapted to the opening of the positioning plate 41, so that the die base 42 slides along the length direction of the pusher slider 10 to fit the opening of the positioning plate 41. Figure 4 An elastic member 45 is provided at the opening of the positioning plate 41. This elastic member 45 is a spring, one end of which is connected to the bend of the positioning plate 41, and the other end of which is connected to the die base 42. This elastic member 45 ensures that, in a natural state, one end of the lower die base 31 always extends beyond the positioning plate 41 and beyond the mounting frame 2. When an external force is applied, causing the die base 42 to extend into the positioning plate 41 along the length of the pusher slide 10, the elastic member 45 is compressed.

[0072] Reference Figure 7 and Figure 11 The mounting frame 2 is further provided with a drive seat 43, one end of which protrudes from the mounting frame 2 and is located above the die base 42. The bottom side of the die base 42 abuts against a support base 44, which is connected to the drive seat 43 by bolts. The support base 44 supports the bottom of the die base 42, thereby ensuring that the die base 42 slides along the length direction of the pusher slide 10.

[0073] Reference Figure 4 and Figure 5A mold block 46 is integrally formed on the side of the die base 42 facing away from the elastic member 45. The mold block 46 matches the shape of the top stop 18. In its natural state, the elastic member 45 causes the mold block 46 to abut against the main feed base 6 and be positioned above the outer lower die. When the first cylinder 19 drives the pusher slide 10 to move along the length of the pusher chute 9, a top stop 18 located in the pusher chute 9 is pushed onto the mold block 46. The stopper 14 and the mold block 46 clamp the top stop 18, thereby preventing it from falling during the pusher process. At the same time, the elastic member 45 helps to buffer the pusher process, preventing deformation of the top stop 18 caused by rigid collisions. The shape of the mold block 46 matches that of the top stop 18, which helps to better support the top stop 18. The pusher slide 10 is reset by the first cylinder 19, at which time the mold block 46 supports the top stop 18.

[0074] Reference Figure 5 and Figure 11 The die base 42 is also integrally formed with a guide block 47, which is on the same side as the mold block 46. The side of the guide block 47 away from the die base 42 is the inclined side. A first pressing block 48 is movably provided on the driving base 43. The first pressing block 48 is in the form of an elongated strip and is distributed along the height direction of the die base 42. When the first pressing block 48 is driven to move along the height direction of the die base 42, the first pressing block 48 abuts against the main body of the top stop 18 and pushes the inclined side of the guide block 47, causing the die base 42 to slide along the length direction of the pusher slide 10. At this time, the elastic member 45 is compressed.

[0075] Reference Figure 11 and Figure 12 A second pressure block 49 is movably connected to the first pressure block 48. The second pressure block 49 is also elongated and extends along the length of the first pressure block 48. The side of the first pressure block 48 closest to the mold block 46 protrudes beyond the second pressure block 49. A pick-up edge 491 is provided at the end of the second pressure block 49, which matches the shape of the main body of the top stop 18. This pick-up edge 491 facilitates the removal of the top stop 18 from the mold block 46. When the first pressure block 48 is driven to move along the height of the mold base 42, the mold base 42 extends into the positioning plate 41 along the length of the pusher slide 10. Simultaneously, the first pressure block 48 drives the second pressure block 49 to move, causing the pick-up edge 491 to abut against the main body of the top stop 18, removing the top stop 18 from the mold block 46. Continued movement of the first pressure block 48 then passes the buckle leg of the top stop 18 through and fastens it to the fabric tape on the outer lower film 35.

[0076] Reference Figure 8 and Figure 10A guide groove 15 is provided at the outer lower membrane 35 corresponding to the buckle feet of the top stop 18. The guide groove 15 is used to guide the buckle feet of the top stop 18 to bend correctly. Four guide grooves 15 are provided, and the four guide grooves 15 correspond to the four buckle feet one by one, and the four guide grooves 15 are all close to the bifurcated blocking rod 33. When the top stop 18 passes through the cloth tape on the outer lower membrane 35 through the continuous movement of the first pressing block 48, the four buckle feet of the top stop 18 are guided by the guide grooves 15 to bend correctly, thereby fastening the top stop 18 to the branch of the Y-shape of the zipper bag, and improving the accuracy and efficiency of installation through the guide grooves 15.

[0077] During installation, the first cylinder 19 drives the push slider 10 to move along the length direction of the push chute 9, so that an upper stop 18 located in the push chute 9 is pushed onto the mold block 46, and the upper stop 18 is clamped by the stop block 14 and the mold block 46, and the first cylinder 19 drives the push slider 10 to reset, so that the mold block 46 supports the upper stop 18. By driving the first pressing block 48 to move along the height direction of the die base 42, the first pressing block 48 pushes the guide block 47, and the die base 42 extends into the positioning plate 41 along the length direction of the pusher slide 10, compressing the elastic member 45. At the same time, the first pressing block 48 drives the second pressing block 49 to move, causing the material removal edge 491 to abut against the main body of the top stop 18, removing the top stop 18 from the mold block 46. The first pressing block 48 continues to move, and the buckle legs of the top stop 18 are passed through and fastened to the fabric tape on the outer lower film 35. Then, the first pressing block 48 continues to move, passing the buckle legs of the top stop 18 through the fabric tape on the outer lower film 35. Guided by the guide groove 15, the four buckle legs of the top stop 18 are properly bent, thereby fastening the top stop 18 to the Y-shaped branch of the zipper bag. When the first pressing block 48 is driven to reset, it drives the second pressing block 49 to reset, and the elastic force of the elastic member 45 resets the die base 42, the mold block 46, and the guide block 47.

[0078] In addition, refer to Figure 7 and Figure 12 The driving seat 43 is further provided with a driving assembly 16 for driving the first pressing block 48 to move. Specifically, the driving assembly 16 includes a driving motor 161 provided on the driving seat 43, a rotating shaft 162 passing through the driving seat 43, and a rotating disk 163 provided at one end of the rotating shaft 162.

[0079] Reference Figure 7The drive end of the drive motor 161 is fitted with a first transmission wheel (not shown). A second transmission wheel 164 is fitted on the end of the rotating shaft 162 facing away from the rotating disk 163. The second transmission wheel 164 is larger than the first transmission wheel. A transmission belt is wound between the second transmission wheel 164 and the first transmission wheel. The first transmission wheel, the second transmission wheel 164, and the transmission belt are all conventional and will not be described in detail. Thus, the drive motor 161 drives the first transmission wheel to rotate, which in turn drives the transmission belt, which in turn drives the second transmission wheel 164, thereby driving the rotating shaft 162 and the rotating disk 163.

[0080] Reference Figure 7 and Figure 12 The rotating disk 163 is circular and is provided with a connecting shaft 165. Connecting shaft 165 faces away from the second transmission wheel 164 and extends along the length of the rotating shaft 162, near the edge of the rotating disk 163. A first link 166 and a second link 167 are rotatably connected to the connecting shaft 165. Both the first link 166 and the second link 167 are elongated and closely aligned along the length of the connecting shaft 165, with the first link 166 being closer to the rotating disk 163. The first link 166 is rotatably connected to the second pressure block 49 on the side away from the connecting shaft 165, while the second link 167 is rotatably connected to the first pressure block 48 on the side away from the connecting shaft 165. Thus, the first pressure block 48 and the second pressure block 49 are movably connected via the connecting shaft 165, the first link 166, and the second link 167. The drive base 43 is also equipped with a sliding cover plate 168, which faces away from the second pressure block 49. The sliding cover plate 168 and the first pressure block 48 slide together along the height direction of the mold base 42, thereby limiting the sliding movement of the first pressure block 48. Furthermore, the second pressure block 49 and the first pressure block 48 also slide together along the height direction of the mold base 42, thereby making way for the rotation of the turntable 163. Thus, each rotation of the turntable 163 causes the first and second pressure blocks 48, 49 to move along the height direction of the mold base 42 and reset once.

[0081] During driving, the driving motor 161 drives the first transmission wheel to rotate, driving the transmission belt to rotate, and the transmission belt drives the second transmission wheel 164 to rotate, thereby driving the rotating shaft 162 and the turntable 163 to rotate. When the turntable 163 rotates one circle, the first pressure block 48 and the second pressure block 49 move along the height direction of the mold base 42 and reset once.

[0082] In addition, look back Figure 4 and Figure 5 The feeding main seat 6 is also provided with a connecting plate 17, which is connected to the sliding cover plate 168 by bolts to enhance the support of the feeding main seat 6 and prevent the impact generated when the spring is reset from causing the feeding main seat 6 to shake.

[0083] The implementation principles of this application are:

[0084] During feeding, the scattered top stops 18 are arranged into rows by the vibration plate 5 and transported to the feeding trough 8, and the vibration of the vibration plate 5 causes the top stops 18 in the feeding trough 8 to move along the length direction of the feeding trough 8, and enter the pushing chute 9 through a top stop 18 at the end of the feeding trough 8. At this time, the second cylinder 22 drives the upper pressure plate 11 to move along the length direction of the through opening 20, so that the upper pressure plate 11 extends into the feeding trough 8, and fixes the top stop 18 closest to the pushing chute 9, thereby stopping the top stop 18 in the feeding trough 8 from moving forward, thereby ensuring the stability of subsequent feeding. By driving the push slide 10 along the length direction of the push chute 9 by the first cylinder 19, a top stop 18 located in the push chute 9 can be pushed onto the mold block 46, and the top stop 18 is clamped by the stop block 14 and the mold block 46, thereby preventing the top stop 18 from falling during the push process. At the same time, the elastic member 45 is conducive to buffering during the push process, avoiding deformation of the top stop 18 caused by rigid collision, and the shapes of the mold block 46 and the top stop 18 are adapted to each other, which is conducive to better supporting the top stop 18. The push slide 10 is driven to reset by the first cylinder 19, and at this time the mold block 46 supports the top stop 18.

[0085] When installing the zipper tape, place the end of the zipper tape on the tape base 34, the end of the zipper tape on the outer lower membrane 35, and the two side tapes of the zipper tape on the tape base 34, wherein the fastener elements on the tape are respectively located in the two fastener element grooves 23, so that the two side tapes are opposite each other along the width direction of the tape base 34. Furthermore, extend one side of the zipper tape end into the first tape gap 12 and the second tape gap 13 of a cloth pushing slider 36, so that the two side tapes of the zipper tape end are respectively located within the two cloth pushing sliders 36.

[0086] When the zipper tape is installed, the third cylinder 24 drives the cloth pressing plate 37 to move along the height direction of the frame 1, so that the cloth pressing plate 37 abuts the chain base 34 and, at the same time, presses and fixes the zipper tape on the chain base 34, thereby preventing the zipper tape on the chain base 34 from moving. When the cloth pressing plate 37 presses and fixes the zipper tape on the chain base 34, the fourth cylinder 25 drives the forked blocking rod 33 to slide along the length direction of the support portion 312, so that one end of the forked blocking rod 33 extends through the rod gap 38. At this time, the two side strips of the zipper tape are located on both sides of the forked blocking rod 33. The two fifth cylinders 26 respectively drive the two cloth pushing sliders 36 to slide in directions toward each other, so that the two cloth pushing sliders 36 push the two side strips of the zipper tape in a direction toward each other. Through the resistance of the forked blocking rod 33, the two side strips on the outer lower membrane 35 are gradually tightened and overlapped along the edges of the forked blocking rod 33, thereby driving the zipper tape into a Y-shape.

[0087] The first transmission wheel is driven by the driving motor 161 to rotate, which drives the transmission belt to rotate. The transmission belt drives the second transmission wheel 164 to rotate, thereby driving the rotating shaft 162 and the turntable 163 to rotate. When the turntable 163 rotates one circle, the first pressure block 48 and the second pressure block 49 are moved along the height direction of the mold base 42 and reset. At the same time, by driving the first pressing block 48 to move along the height direction of the mold base 42, the first pressing block 48 pushes the guide block 47, and the mold base 42 extends into the positioning plate 41 along the length direction of the pushing slider 10, the elastic member 45 is compressed, and the first pressing block 48 drives the second pressing block 49 to move, so that the material picking edge 491 abuts against the upper stop 18 body, and the upper stop 18 is removed from the mold block 46, and the first pressing block 48 is continuously moved to pass the buckle foot of the upper stop 18 through and fasten it to the cloth tape on the outer lower membrane 35, and then the first pressing block 48 is continuously moved to pass the buckle foot of the upper stop 18 through the cloth tape on the outer lower membrane 35, and the four buckle feet of the upper stop 18 are correctly bent through the guidance of the guide groove 15, so that the upper stop 18 is fastened to the Y-shaped branch of the zipper bag.

[0088] In summary, the zipper tape can be conveniently pinched into a Y-shape, and the materials can be automatically sorted, loaded, and installed at the top stop 18, thereby improving the degree of automation and thus enhancing the installation efficiency.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
