The structure and output method of the feeding device 9 are conventional methods in the field, and therefore will not be described in detail.

[0041] Combine the following Figure 1-Figure 3As shown, the tape guide input device 1 includes a tape guide mechanism 11 and a clamping and pulling mechanism 12. The tape guide mechanism 11 includes a first guide wheel rod 111 and a second guide wheel rod 112 arranged vertically, and a plurality of guide wheels 113 arranged on the first guide wheel rod 111 and the second guide wheel rod 112 arranged vertically.

[0042] See also Figure 2 As shown, the cutting device 2 includes a positioning mechanism 21 and a cutting mechanism 22. The positioning mechanism 21 and the cutting mechanism 22 are arranged in sequence along the direction in which the continuous zipper tape turns around. Figure 2 The direction is opposite to the direction indicated by the arrow F2, and both are conventional structures in the art.

[0043] Recombination Figure 1-Figure 3 As shown, during the zipper tape input process, the continuous zipper tapes are sequentially input laterally along the first guide wheel rod 111, that is, along Figure 2-3 In the direction indicated by the middle arrow F2, the zipper tape passes through the second guide wheel rod 112 and then turns around for transportation. During this process, the clamping motor 121 rotates forward to make the clamping pulley 122 run, thereby driving the clamping slider 125 to slide along the clamping guide rail 124 toward the second guide wheel rod 112, that is, along the Figure 2-3 The clamping and pulling motor 121 rotates in the reverse direction to make the clamping and pulling pulley 122 run, thereby driving the clamping and pulling slider 125 to slide along the clamping and pulling guide rail 124 away from the second guide wheel rod 112, that is, along the clamping and pulling guide rail 124. Figure 2 The zipper tape moves in the reverse direction indicated by the middle arrow F2, thereby turning around along the horizontal U-shaped route to achieve the input and flipping of the zipper tape. When the clamping and pulling slider 125 slides to the end of the clamping and pulling guide rail 124, the positioning mechanism 21 fixes the end of the zipper tape close to the second guide wheel rod 112, and then the cutting mechanism 22 cuts it to obtain a single semi-finished zipper tape.

[0044] Combine the following Figure 1-2 , Figure 4-5As shown, the lateral feeding device 3 is longitudinally arranged below the clamping and pulling mechanism 12, and includes a feeding drive 31, a feeding slider 32, a feeding guide rail 33, a feeding mounting plate 34, and a feeding fixture 35. Among them, the feeding guide rail 33 is longitudinally arranged below the clamping and pulling guide rail 124, the feeding slider 34 is slidably connected to the feeding guide rail 33, the feeding drive 31 is connected below the feeding slider 34, and the feeding fixture 35 is installed above the feeding slider 34 through the feeding mounting plate 34.

[0045] In the present invention, the feed drive member 31 is preferably a rodless cylinder, but is not limited thereto. For example, the feed slider 34 may be driven to reciprocate by cooperation of a motor, a screw rod, and a nut sleeve.

[0046] Continue to view Figure 4-5 As shown, the feed clamp 35 includes an upper clamp group and a lower clamp group. The upper clamp group includes an upper connecting rod 351, an upper cylinder 352, an upper flip block 353 and an upper opening and closing clamp 354. The upper connecting rod 351 is fixed to the feed mounting plate 34 and extends longitudinally. One end of the upper flip block 353 is pivoted to the upper connecting rod 351 and extends upward. The upper opening and closing clamp 354 is vertically fixed to the other end of the upper flip block 353. The upper cylinder 352 is installed on the feed mounting plate 34 and the telescopic end is pivoted to the upper flip block 353. When the telescopic end of the upper cylinder 352 is extended and retracted, the upper flip block 353 is driven to rotate, thereby causing the upper opening and closing clamp 354 to flip up and down. The lower clamp group includes a lower connecting rod 355, a lower cylinder 356, a lower flip block 357 and a lower opening and closing clamp 358. The lower connecting rod 355 is fixed below the upper connecting rod 351 and is parallel thereto. One end of the lower flip block 357 is pivoted to the lower connecting rod 355 and extends downward, that is, the lower flip block 357 and the upper flip block 353 are symmetrically arranged. The lower opening and closing clamp 358 is vertically fixed to the other end of the lower flip block 357, and its protruding direction is the same as that of the upper opening and closing clamp 354. The lower cylinder 356 is installed on the feed mounting plate 34 and the telescopic end is pivoted to the lower flip block 357. When the telescopic end of the lower cylinder 356 is extended and retracted, it drives the lower flip block 357 to rotate, thereby causing the lower opening and closing clamp 358 to flip up and down.

[0047] Recombination Figure 1-2 , Figure 4-5 As shown, when feeding from the side, the telescopic end of the upper cylinder 352 extends to drive the upper flip block 353 to rotate downward, so that the upper opening and closing clamp 354 flips downward, and correspondingly, the telescopic end of the lower cylinder 356 extends to drive the lower flip block 357 to rotate upward, so that the lower opening and closing clamp 358 flips upward, and then the upper opening and closing clamp 354 and the lower opening and closing clamp 358 that are flipped and attached hold the semi-finished zipper tape. Figure 1After being transported to the zipper tape transverse conveying device 4 in the direction indicated by the middle arrow F1, the telescopic ends of the upper cylinder 352 and the lower cylinder 356 are retracted, driving the upper flip block 353 to rotate upward and the lower flip block 357 to rotate downward, so that the upper opening and closing clamp 354 and the lower opening and closing clamp 358 are released, and then the feed drive member 31 drives the feed clamp 35 along the Figure 1 Slide in the opposite direction indicated by the middle arrow F1 to retract.

[0048] Combine the following Figure 1 , Figure 6-Figure 7 As shown, the zipper tape transverse conveying device 4 includes a linear module, a conveying cantilever 44, and a conveying fixture 45. The linear module is transversely arranged in front of the upper stop forming mold set 5, the conveying cantilever 44 is slidably connected to the linear module, and the upper end of the conveying cantilever 44 is equipped with a conveying fixture 45, and the linear module can drive the conveying cantilever 44 to slide back and forth transversely.

[0049] In a specific embodiment of the present invention, the linear module includes a conveying motor 41, a conveying screw (not shown), a conveying nut sleeve (not shown), a conveying guide rail 42, and a conveying slider 43. The conveying guide rail 42 is transversely arranged in front of the upper stop forming mold set 5, and one end of the conveying guide rail 42 extends into the mold base 51 (described later). The conveying screw is transversely arranged below the conveying guide rail 42 and one end is fixedly connected to the driving shaft of the conveying motor 41. The conveying nut sleeve is threadedly connected to the conveying screw and fixedly connected to the conveying slider 43. The conveying slider 43 is slidably connected to the conveying guide rail 42, and the conveying slider 43 is fixedly connected to the lower end of the conveying cantilever 44. When the conveying motor 41 drives the conveying screw to rotate forward or reverse, the conveying nut sleeve is reciprocated along the conveying screw, thereby driving the conveying slider 43 to reciprocate on the conveying guide rail 42, and the conveying slider 43 drives the conveying fixture 45 to slide reciprocatingly along the conveying guide rail 42, and repeatedly conveys the semi-finished zipper tape to the upper stop forming mold set 5.

[0050] It is understandable that the linear module is not limited to the above structure. For example, in another embodiment, the linear module is a rodless cylinder, which drives the conveying cantilever 44 to slide back and forth, so as to simplify the structure of the zipper tape transverse conveying device 4. In another embodiment, the linear module can also be a belt module, which drives the conveying cantilever 44 to slide back and forth.

[0051] like Figure 7As shown, the conveying cantilever 44 includes a column 441, a beam 442, a left arm 443, and a right arm 444. The lower end of the column 441 is fixed to the conveying slider 43, and the upper end of the column 441 is fixedly connected to the front end of the beam 442. The beam 442 is horizontally and longitudinally arranged and straddles the top of the conveying guide rail 42. The front end of the beam 442 is fixedly connected to the left arm 443, and the rear end of the beam 442 is fixedly connected to the right arm 444. The left arm 443 and the right arm 444 are arranged opposite to each other, and the conveying clamp 45 is respectively installed on the left arm 443 and the right arm 444.

[0052] The conveying clamp 45 includes a first pneumatic clamp 451, a second pneumatic clamp 452, a first linear motor 453 and a second linear motor 454. The first linear motor 453 is installed on the left arm 443 and connected to the first pneumatic clamp 451, and the first linear motor 453 can drive the first pneumatic clamp 451 to move longitudinally; the second linear motor 454 is installed on the right arm 444 and connected to the second pneumatic clamp 452, and the second pneumatic clamp 452 is arranged opposite to the first pneumatic clamp 451, and the second linear motor 454 is used to drive the second pneumatic clamp 452 to move longitudinally.

[0053] Combination Figure 1 , Figure 6-Figure 7 As shown, in the present invention, the head threading device includes a slider holding mechanism 46, a slider regularizing mechanism 47, and a slider conveying mechanism (not shown) connected therebetween; the slider holding mechanism 46 is arranged on the side of the conveying guide rail and below the conveying fixture 45, and is used to clamp and fix the slider, the slider regularizing mechanism 47 uniformly transports the disordered sliders to the slider conveying mechanism, and the slider conveying mechanism transports the sliders to the slider holding mechanism 46 one by one. Among them, the structures and working methods of the slider holding mechanism 46, the slider regularizing mechanism 47, and the slider conveying mechanism are all conventional methods in the art, and therefore will not be described in detail.

[0054] Continue to combine Figure 1 , Figure 6-Figure 7As shown, when conveying the semi-finished zipper tape, the conveying motor 41 drives the conveying screw to rotate so that the conveying nut sleeve drives the conveying slider 43 to move to the front end of the guide rail 42, and the conveying slider 43 moves the conveying clamp 45 to the front end of the conveying guide rail 42 through the conveying cantilever 44, and then clamps the semi-finished zipper tape through the first pneumatic clamp 451 and the second pneumatic clamp 452 respectively. After the feeding clamp 35 releases the semi-finished zipper tape, the conveying motor 41 drives the conveying screw to rotate in the opposite direction so that the conveying nut sleeve drives the conveying slider 43 to slide along the conveying guide rail 42 to the rear end, that is, slides in the direction indicated by the arrow F2, thereby pulling the semi-finished zipper tape to move toward the upper stop forming mold set 5. During this conveying process, the first linear motor 453 drives the first pneumatic clamp 451 and the second linear motor 454 drives the second pneumatic clamp 452 to move forward and backward in the longitudinal direction to tear open the semi-finished zipper tape. When the semi-finished zipper tape passes through the slider holding mechanism 46, the slider is put on. Then, the conveying cantilever 44 is driven to continue to drive the conveying clamp 45 to slide in the direction indicated by the arrow F2 to convey the semi-finished zipper tape to the upper stop forming mold set 5.

[0055] When the conveying slide block 43 slides to the rear end of the conveying guide rail 42, the conveying motor 41 stops running, and the first pneumatic clamp 451 and the second pneumatic clamp 452 enter the die base 51 of the upper stop forming mold set 5 until the upper mold assembly 52 and the lower mold assembly 53 (described later) of the upper stop forming mold set 5 are closed, and then the first pneumatic clamp 451 and the second pneumatic clamp 452 release the semi-finished zipper tape. Then, the conveying motor 41 drives the conveying screw to rotate in the reverse direction so that the conveying nut sleeve drives the conveying slide block 43 to slide in the reverse direction indicated by the arrow F2 until the conveying slide block 43 slides to the front end of the conveying guide rail 42 again to receive the next semi-finished zipper tape.

[0056] Combine the following Figure 6 , Figure 8-Figure 9 As shown, the zipper tape transverse conveying device 4 further includes an auxiliary conveying mechanism 48, which is arranged between the slider holding mechanism 46 and the upper stop forming mold set 5.

[0063] like Fig.13 As shown, more specifically, the driving assembly 54 further includes a guide rod 546, a guide plate 547, a bottom plate 548, a suspension column 549, an upper connecting plate 550 and a guide sleeve 551.

[0064] Combination Figure 10-15 As shown, when the zipper tape is clamped by the zipper tape transverse conveying device 4 and conveyed to the position corresponding to the upper mold 521 and the lower mold 531, the first motor 541 is activated and drives the lower mold 531 to move up and close with the upper mold 521. At this time, the two positioning columns 524 extend into the two positioning holes 554 respectively, and at the same time, the upper pressure belt block 523 and the lower pressure belt block 555 are pressed together to clamp the semi-finished zipper tape for positioning, and the upper mold core 522 and the lower mold core 552 are closed to injection mold the upper stop. After the upper stop is formed, the first motor 541 is activated and drives the lower mold 531 to move down, and the finished zipper tape with the upper stop is output from the side by the lateral discharge device 6. In the above process, the opening and closing of the upper stop molding mold is completed only by the up and down movement of the lower mold assembly 53, so the power consumption when the motor is driven can be greatly saved, achieving the purpose of saving energy and reducing production costs.

[0065] Combine the following Figure 10-11 , Figure 16-18 As shown, the injection molding device 6 includes a fixing frame 61, an injection mechanism 62 and a lifting mechanism 63.

In one embodiment of the present invention, the lower end of the fixing frame 61 is H-shaped, and the opening at the lower end forms the second cleaning hole 611. The lifting mechanism 63 is installed on the fixing frame 61 and connected to the injection mechanism 62, and is used to drive the injection mechanism 62 to rise and fall.

[0066] Specifically, the injection mechanism 62 is installed on the fixed frame 61 and is located above the mold base 51. The injection mechanism 62 includes a barrel 621, a hopper 622, a second motor 623 and a synchronous wheel transmission assembly. The lower end of the barrel 621 is provided with an injection nozzle connected to the upper mold 521. The hopper 622 is connected to the upper end of the barrel 621 for injecting injection material into the barrel 621. The second motor 623 is connected to the upper end of the barrel 621 through the synchronous wheel transmission assembly to drive it to rotate.

When the second motor 623 drives the first pulley 624 to rotate, the barrel 621 is driven to rotate through the belt 626 and the second pulley 625.

[0068] Furthermore, the injection mechanism 62 further includes a first connecting plate 627, a second connecting plate 628 and a third connecting plate 629, the first connecting plate 627 and the third connecting plate 629 are respectively vertically connected to the second connecting plate 628 and protrude in opposite directions, and the first connecting plate 627 and the third connecting plate 629 are parallel to each other, that is, there is a certain height difference between the first connecting plate 627 and the third connecting plate 629. The upper end of the barrel 621 is mounted on the first connecting plate 627, and the second motor 623 is mounted on the third connecting plate 629, so that the barrel 621 and the second motor 623 are respectively arranged on both sides of the second connecting plate 628 with a certain distance, so as to facilitate the installation with the lifting mechanism 63, so as to achieve the purpose of compact structure.

[0069] Continue to combine Figure 10-11 , Figure 16-18 As shown, the lifting mechanism 63 includes a lifting cylinder 631, a vertical fixed plate 632, a lifting slider 633, a lifting rail 634, a horizontal fixed plate 635 and a connecting column 636. The lifting rail 634 is fixed to the fixed frame 61 and extends along its height direction, the vertical fixed plate 632 is slidably connected to the lifting rail 634 through the lifting slider 633, the horizontal fixed plate 635 is vertically fixed to the vertical fixed plate 632, the barrel 621 is inserted through the horizontal fixed plate 635 so that the injection nozzle at the lower end is connected to the upper mold 521, and the first connecting plate 627 at the upper end of the barrel 621 is parallel to the horizontal fixed plate 635, and the two ends of the first connecting plate 627 in the length direction protrude from the horizontal fixed plate 635. At both ends of the fixing frame 61, two connecting columns 636 are respectively connected between the horizontal fixing plate 635 and the first connecting plate 627, and the two connecting columns 636 are arranged on both sides of the barrel 621; the lifting cylinder 631 is fixed to the fixing frame 61 and connected to the first connecting plate 627. When the lifting cylinder 631 pushes the first connecting plate 627, it will drive the vertical fixing plate 632 to slide up and down along the lifting rail 634 through the connecting column 636 and the horizontal fixing plate 635, thereby driving the barrel 621 and the second motor 623 to move up and down as a whole. In addition, the second connecting plate 628 is arranged parallel to the fixing frame 61, and the second motor 623 of the injection mechanism 62 is located on the outside of the fixing frame 61, that is, the second motor 623 and the barrel 621 are arranged on both sides of the fixing frame 61, so that the structure of the entire injection molding device 6 is compact and the occupied space is reduced. The lifting mechanism 63 has a simple structure and is easy to drive. The energy consumption required in the process of driving the injection mechanism 62 to lift is also greatly reduced, which is conducive to reducing production costs and saving energy.

[0070] like Figure 16-18As shown, the lifting mechanism 63 drives the barrel 621 to rise and fall through two lifting cylinders 631. Correspondingly, two mounting plates 637 are fixed on both sides of the fixed frame 61. The two mounting plates 637 are located at the same horizontal height. The two lifting cylinders 631 are respectively fixed to the two mounting plates 637 and connected to the two ends of the first connecting plate 627. The two lifting cylinders 631 synchronously push the two ends of the first connecting plate 627 to drive it to rise and fall, so that the force is balanced.

[0071] Continue to combine Figure 10-11 As shown, in the present invention, the blowing device 7 includes a blowing nozzle 71, a first material receiving trough 72, a second material receiving trough 73 and an outer cover 74. The blowing nozzle 71 is installed on the front side of the mold base 71, that is, on the side of the open end of the mold base 71, the first material receiving trough 72 is clamped in the first cleaning hole 514 and the second cleaning hole 611 and is arranged obliquely, the upper end of the first material receiving trough 72 is connected to the lower mold 531, the second material receiving trough 73 is arranged below the fixed frame 61 and is arranged obliquely, and the oblique direction of the second material receiving trough 73 is staggered with the oblique direction of the first material receiving trough 72, thereby saving installation space, and the outer cover 74 is fixed to the fixed frame 61 and covers the outside of the second cleaning hole 611. When the blowing nozzle 71 is working, the gas blown out blows the waste on the lower mold 531 into the first cleaning hole 514 and the second cleaning hole 611. The waste falls into the first receiving groove 72 and then slides down it into the second receiving groove 73, and then automatically slides down and is discharged along the second receiving groove 73. In this way, the purpose of online cleaning of the lower mold 531 at any time is achieved, the cleanliness of the upper stop molding mold set 5 is maintained, and the injection molding quality is guaranteed. On the other hand, there is no need for people to clean or stop the machine to clean the upper stop molding mold set 5, thereby improving production efficiency.

[0072] Continue to combine Figure 1 , Figure 19-20As shown, the lateral discharge device 8 includes a discharge drive 81, a first discharge guide 82, a first discharge slider 83, a second discharge guide 84, a second discharge slider 85, a discharge cylinder 86, a finger cylinder 87 and a discharge fixture 88. The first discharge guide 82 is longitudinally arranged on the side of the upper stop forming mold set 5, the first discharge slider 83 is slidably connected to the first discharge guide 84 and connected to the discharge drive 81, and the discharge drive 81 drives the first discharge slider 83 to slide back and forth along the first discharge guide 84. The second discharging guide rail 84 is installed on the first side plate 8a and also extends longitudinally. The first side plate 8a is fixed to the first discharging slider 83. The second discharging slider 85 is slidably connected to the second discharging guide rail 84, and the second side plate 8b is fixed on the second discharging slider 85. A finger cylinder 87 is installed at the front end of the second side plate 8b. The finger cylinder 87 is connected to the discharging fixture 88. The finger cylinder 87 is used to drive the discharging fixture 88 to open or close. The rear end of the second side plate 8b is connected to the discharging cylinder 86. The discharging cylinder 86 is installed on the first side plate 8a. The discharging cylinder 86 can drive the second side plate 8b to slide along the second discharging guide rail 84 to realize the longitudinal sliding of the discharging fixture 88.

[0073] In the present invention, the discharging driving member 81 is preferably a rodless cylinder, but is not limited thereto. For example, the first discharging sliding block 83 may be driven to reciprocate by cooperation of a motor, a screw rod, and a nut sleeve.

[0074] Recombination Figure 1 , Figure 19-20 As shown in the figure, when the material needs to be discharged laterally after the upper stop injection molding, first, the discharge drive member 81 drives the first discharge slide block 83 to move along the first discharge guide rail 84 to the upper stop molding mold set 5, that is, the first discharge slide block 83 moves along the Figure 1 , Figure 19-20 The first side plate 8a slides in the opposite direction to the direction indicated by the middle arrow F3, so that the first side plate 8a drives the second side plate 8b, the discharge cylinder 86, the finger cylinder 87, and the discharge clamp 88 installed thereon to move as a whole. After the first discharge slider 83 slides to the front end of the first discharge guide rail 84, the discharge drive member 81 stops running; then, the finger cylinder 87 drives the discharge clamp 88 to open, and the discharge cylinder 86 pushes the second side plate 8b to continue to move in the opposite direction indicated by the arrow F3 along the second discharge guide rail 84. When the second discharge slider 85 moves to the front end of the second discharge guide rail 84, the discharge clamp 88 extends into the upper stop molding mold set 5. At this time, the finger cylinder 87 drives the discharge clamp 88 to close and clamp the finished zipper tape.

[0075] When discharging the material laterally, the discharging driving member 81 first drives the first discharging slide block 83 to slide in the direction indicated by the arrow F3, so that the first side plate 8a drives the second side plate 8b, the discharging cylinder 86, the finger cylinder 87, and the discharging clamp 88 to move as a whole. When the first discharging slide block 83 slides to the rear end of the first discharging guide rail 84, the discharging clamp 88 corresponds to the clamp of the unloading device 9; then, the finished zipper tape is clamped by the clamp of the unloading device 9, and at this time, the finger cylinder 87 drives the discharging clamp 88 to open to release the finished zipper tape; then, the discharging cylinder 86 drives the second side plate 8b to slide toward the rear end of the first discharging guide rail 88, that is, along the Figure 1 , Figure 19-20 The unloading device 9 moves in the direction indicated by the middle arrow F3, so that the finished zipper tape can be driven to move horizontally for output.

[0076] In the present invention, the lateral discharge device 8 is set with a two-stage stroke to prevent the unloading device 9 from pulling the zipper tape inconveniently or scratching the zipper tape due to the discharge clamp 88 not opening at a large enough angle, so that the lateral discharge of the zipper tape is smoother. At the same time, the lateral discharge can shorten the discharge time of the zipper tape, thereby shortening the processing cycle of the upper stop molding mold set 5, improving production efficiency, and making the structure of the entire production line more compact.

[0077] Combine again below Figure 1-Figure 20 As shown, the working principle of the injection zipper cutting, threading and injection top stop integrated machine of the present invention is explained.

[0078] First, the continuous zipper tape is turned around and fed along a horizontal U-shaped route through the tape guide mechanism 11 to realize the turning over of the zipper tape. The clamping and pulling mechanism 12 clamps the end of the zipper tape and pulls it to the end, and the other end of the zipper tape is fixed by the positioning mechanism 21. The zipper tape is cut by the cutting mechanism 22 to obtain a semi-finished zipper tape, such as Figure 1-3 shown.

[0079] Then, the feeding fixture 35 of the lateral feeding device 3 clamps the semi-finished zipper tape and moves along the longitudinal direction ( Figure 1 The semi-finished zipper tape is moved in the direction indicated by the middle arrow F1 to be sent into the zipper tape transverse conveying device 4. When the conveying clamp 45 of the zipper tape transverse conveying device 4 clamps the semi-finished zipper tape, the feeding clamp 35 is released and returned.

[0080] Next, the zipper tape transverse conveying device 4 drives its input clamp 45 to clamp the semi-finished zipper tape and convey it in the transverse direction ( Figure 1During this process, the slider is put on after passing through the slider holding mechanism 46, and then the conveying fixture 45 is driven to continue sliding in the direction indicated by the arrow F2. When the first pneumatic clamp 451 and the second pneumatic clamp 452 of the input fixture 45 move into the die base 51 and are conveyed to between the upper die 521 and the lower die 531, the driving assembly 54 operates to drive the lower die 531 to move upward and the upper die 521 to close. Then the first pneumatic clamp 451 and the second pneumatic clamp 452 release the semi-finished zipper tape and are driven by the linear module to return horizontally to clamp the next semi-finished zipper tape.

[0081] The semi-finished zipper tape is formed into an upper stop in the upper stop forming mold set 5, and the process is as described above. The waste generated during the injection molding process is blown toward the lower mold 531 by the blowing nozzle 71 of the blowing device 7, and the gas blows the waste into the first cleaning hole 514 and the second cleaning hole 611, so that the waste automatically slides down along the first receiving groove 72 to the second receiving groove 73, and automatically slides down along the second receiving groove 73 for recovery. In this process, the outer cover 74 prevents the blown waste from flying around and contaminating other parts of the equipment, thereby ensuring the cleanliness of the upper stop forming mold set 5 and other equipment. Figure 10-11 shown.

[0082] After the injection molding of the upper stop is completed, the finished zipper tape is obtained. At this time, the lateral discharge device 8 drives its discharge fixture 88 to move longitudinally into the die base 51 of the upper stop molding die set 5, and the finished zipper tape is clamped by the discharge fixture 88. At this time, the upper die 521 and the lower die 531 are opened to release the finished zipper tape, and the lateral discharge device 8 drives the discharge fixture 88 to move longitudinally ( Figure 1 The machine moves in the direction indicated by the middle arrow F3 to complete the lateral discharge.

[0083] After the lateral discharging device 8 outputs the finished zipper tape, the finished zipper tape is clamped by the clamp of the unloading device 9 and pulled out in the lateral direction, and then outputted by the unloading device 9.

[0084] In summary, due to the injection molding zipper cutting, threading, and injection molding upper stop integrated machine of the present invention, firstly, the side feeding device 3 and the side discharging device 8 are respectively arranged perpendicularly to the zipper tape transverse conveying device 4, thereby realizing the side feeding and side discharging of the zipper tape, thereby shortening the feeding and discharging time of the zipper tape, and then shortening the overall processing cycle of the zipper tape, and improving production efficiency; secondly, the guide belt input device 1 and the zipper tape transverse conveying device 4 are arranged in parallel and the conveying direction of both is transverse, and the side feeding device 3 and the side discharging device 8 are respectively arranged perpendicularly between the two, so that the structure of the entire production line is more compact.

[0085] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
