TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting, and particularly relates to a cutting treatment device for zipper production. BACKGROUND

[0002] Zipper, as an innovative connector that realizes the convenient combination and separation of articles through the precise design of continuous chain teeth, has penetrated into all aspects of our daily life, especially in clothing, bags, tents and various fashion accessories. Its application is so widespread that it is almost everywhere, greatly enriching our wearing and carrying experience. In the manufacturing process of the zipper, the cutting process plays a crucial role, which undertakes the task of accurately dividing the long strip-shaped zipper raw material into multiple small sections with relatively uniform length. These small sections of zipper are then used to sew onto various products to meet the needs of different design styles and size specifications.

[0003] However, in actual operation, due to the lack of effective zipper tensioning mechanism, the zipper material often cannot maintain sufficient tension during cutting, which directly leads to the difficulty in ensuring the accuracy of the cutting position. Therefore, the length of the cut zipper section often cannot be completely consistent, sometimes with deviations, which not only brings great challenges to the subsequent assembly work, increases the difficulty and cost of manual adjustment, but also may affect the overall aesthetics and durability of the final product in the length of the zipper section, reducing the satisfaction of consumers and the competitiveness of the brand.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the present application.

[0033] Please refer to Figure 1 , Figure 3 and Figure 4It can be seen that the base frame 1 is firmly connected in the desired position by the reserved mounting lug. The base frame 1 has a protective baffle 2 guided by a threaded rod on one side, and a screw is threadedly connected to the threaded rod. A fastening push spring 3 is arranged outside the threaded rod between the screw and the protective baffle 2. The fastening push spring 3 is used to force the protective baffle 2 to always have a tendency to move towards the base frame 1. On this basis, combined with Figure 5 and Figure 8 It can be seen that the protective baffle 2 has a protective bottom plate 201 movably mounted on the side of the cylindrical rod. The protective bottom plate 201 can move within a certain range on the protective baffle 2. When the protective bottom plate 201 moves with the protective baffle 2 and approaches the base frame 1, the protective bottom plate 201 will eventually reach below the base frame 1. The spacing between the base frame 1 and the protective baffle 2 and the top surface of the protective bottom plate 201 can provide a single stable conveying path for the zipper element 26.

[0034] The base frame 1 movably has an adjusting slide 14 guided by a cylindrical rod. As shown in Figure 2 , the adjusting slide 14 is movably connected to the top of the base frame 1. An adjusting spring 140 is arranged outside the cylindrical rod between the adjusting slide 14 and the base frame 1 to force the adjusting slide 14 to always have a tendency to move along the base frame 1. More specifically, combined with Figure 2 and Figure 4 It can be seen that the adjusting slide 14 movably has a driven pressure wheel 250. Correspondingly, the adjusting slide 14 also movably has a motor 16 fastened by a bolt. The output shaft of the motor 16 is fixedly connected to a driving roller 25 below the driven pressure wheel 250. Since the installation position of the motor 16 in the vertical direction of the adjusting slide 14 can be adjusted as needed, the spacing between the driving roller 25 and the driven pressure wheel 250 can be relatively changed. When the zipper element 26 passes between the driving roller 25 and the driven pressure wheel 250, the zipper element 26 can be stably clamped. Furthermore, in actual application, the outer sides of the driving roller 25 and the driven pressure wheel 250 are preferably made of rubber. The certain elastic deformation of the rubber ensures that the two can stably clamp the zipper element 26 without damaging it.

[0035] The lower cutter 22 is fastened to the base frame 1 by a bolt. From Figure 4 It can be seen that the lower cutter 22 is located on one side of the driving roller 25 and the driven pressure wheel 250. When the driving roller 25 rotates, it can convey the zipper element 26 above the lower cutter 22. Not only that, combined with Figure 1 , Figure 9 and Figure 12It can be seen that the base frame 1 outside has a cylinder 8 connected by bolts, and the cylinder 8 is connected with the air pump, which can make the support top frame 9 fixed on the air rod of the cylinder 8 move up and down. The push plate seat 10 is fixed at the bottom of the support top frame 9 and above the base frame 1 and the protective baffle 2, and the push plate seat 10 has an upper cutter 11 connected by bolts on the side. When the upper cutter 11 and the lower cutter 22 move relatively close, the zipper 26 between them can be cut off, and finally the cutting work of the zipper 26 is realized. Moreover, the push plate seat 10 is provided with a trapezoidal protrusion on the outside bottom, as shown in Figure 9 When the support top frame 9 pushes the push plate seat 10 to move downward and the upper cutter 11 does not contact the lower cutter 22, the trapezoidal protrusion on the outside of the push plate seat 10 will first reach between the base frame 1 and the protective baffle 2, forcing the protective baffle 2 to move away from the base frame 1 and pressing the push spring 3.

[0036] On this basis, combined with Figure 1 , Figure 2 , Figure 4 , Figure 9 and Figure 10 It can be seen that the base frame 1 is movably installed with a pressing seat 5, and the pressing seat 5 and the bottom of the base frame 1 are connected with a pressing spring 500. The pressing seat 5 is always pushed by the pressing spring 500 and has a downward movement tendency. The pressing seat 5 is fixedly installed with a reset top rod 7 on the side of the protective baffle 2. Correspondingly, the side of the protective baffle 2 is provided with a reset sliding groove 202, which is an inclined groove for limiting the upward and downward movement of the reset top rod 7. Under normal circumstances, the protective baffle 2 is pushed by the elastic force of the push spring 3 to move close to the base frame 1. At the same time, the reset top rod 7 is pushed by the reset sliding groove 202 to move upward along the reset sliding groove 202, and at the same time, the pressing spring 500 is compressed. When the trapezoidal protrusion on the push plate seat 10 pushes the protective baffle 2 outward, the protective baffle 2 moves away from the base frame 1. Therefore, under the elastic pulling of the pressing spring 500, the pressing seat 5 moves downward. Finally, by moving the bottom of the pressing seat 5 close to the base frame 1, the zipper 26 between them can be clamped. Moreover, in order to ensure that the zipper 26 can stop automatically after moving below the pressing seat 5, combined with Figure 9 It can be seen that the base frame 1 is fixedly installed with a photoelectric sensor 23 below the pressing seat 5. When the zipper 26 passes above the photoelectric sensor 23, the zipper 26 will block the photoelectric sensor 23, forcing the photoelectric sensor 23 to generate an electric signal and transmit it to the control computer 4 fixed on the outside of the base frame 1. After data processing by the control computer 4, the motor 16 stops working, ensuring that the zipper 26 can stop automatically after reaching above the photoelectric sensor 23, providing necessary conditions for subsequent fixed-length cutting of the zipper 26.

[0037] ReferenceFigure 1 It can be seen that the end of the support top frame 9 is provided with an upper wedge-shaped sliding block 12 which is fastened by a bolt, and the adjusting sliding seat 14 is provided with a lower wedge-shaped sliding block 18 which is fastened by a bolt. When the upper wedge-shaped sliding block 12 moves downward along with the support top frame 9, the upper wedge-shaped sliding block 12 will finally be in close contact with the lower wedge-shaped sliding block 18. With the downward movement of the upper wedge-shaped sliding block 12, the lower wedge-shaped sliding block 18 will be pushed by the upper wedge-shaped sliding block 12 to move the adjusting sliding seat 14 in the direction of the compression adjusting spring 140. As mentioned above, when the zipper element 26 moves to the upper side of the photoelectric sensor 23 after being conveyed by the driving roller 25 and the driven pressure roller 250, the motor 16 will stop working. In addition, the control computer 4 will drive the air pump to pull the support top frame 9 downward through the air cylinder 8 and the air rod. During the downward movement of the support top frame 9, the trapezoidal protrusions on the outer side of the push plate seat 10 will first abut against the protective baffle 2, so that the protective baffle 2 moves away from the base frame 1. Under the elastic pushing of the pressing spring 500, the pressing seat 5 moves downward until the pressing seat 5 and the base frame 1 firmly clamp the zipper element 26. Then, with the downward movement of the support top frame 9 and the upper wedge-shaped sliding block 12, the upper wedge-shaped sliding block 12 pushes the lower wedge-shaped sliding block 18 to move and compresses the adjusting spring 140 at the same time. During this process, since the driving roller 25 and the driven pressure roller 250 clamp the zipper element 26, when the receiving baffle 24 moves away from the lower cutter 22, the zipper element 26 is pulled tight by the clamping between the driving roller 25 and the driven pressure roller 250. At this moment, one end of the zipper element 26 is clamped by the pressing seat 5 and the base frame 1, and the other end is pulled tight by the driving roller 25 and the driven pressure roller 250. Therefore, with the downward movement of the support top frame 9 and the upper cutter 11, the cutting of the zipper element 26 is finally realized by the relative movement between the upper cutter 11 and the lower cutter 22.

[0038] In order to ensure that the subsequent zipper element 26 can be continuously cut, in combination with Figure 4 , Figure 9 and Figure 10It can be seen that the side of the adjusting slide 14 is fixedly provided with a stop rod 15 which is movable in the base frame 1, and a buffer cavity 100 is formed in the inner side of the base frame 1 and located at the end of the stop rod 15. When the stop rod 15 passes through the overflow groove 101 formed in the top of the base frame 1, the stop rod 15 entering the buffer cavity 100 will extrude the air in the buffer cavity 100, so that the extruded air can only slowly flow out from the damping hole 102 formed in the end of the base frame 1. Therefore, it can be seen that the movement speed of the stop rod 15 extruding the buffer cavity 100 will be greatly reduced when the stop rod 15 passes through the overflow groove 101. Furthermore, the side of the stop rod 15 is provided with a transition inclined portion 151, and the side of the pressure seat 5 is movably provided with a limiting top rod 6 which is symmetrical to the reset top rod 7. The limiting top rod 6 and the pressure seat 5 are connected by a limiting top spring 600. The limiting top rod 6 is pushed by the elastic force of the limiting top spring 600 and abuts against the limiting sliding groove 103 formed in the inner side of the base frame 1. The limiting sliding groove 103 is a stepped groove, and the transition inclined portion 151 can be used to transition between the two groove depths, so that when the pressure seat 5 moves downward, the limiting top rod 6 can pass through the transition inclined portion 151 and enter the limiting sliding groove 103. Similarly, if the transition inclined portion 151 is away from the limiting top rod 6, when the outer side of the pressure seat 5 abuts against the limiting top rod 6, the downward movement of the pressure seat 5 will be limited.

[0039] Furthermore, referring to Figure 2 and Figure 11 It can be seen that the adjusting slide 14 is movably provided with a gear 17 which is coaxially and tightly connected with the driven pressure wheel 250, and the side of the adjusting slide 14 is movably provided with a detection slide 19. The detection slide 19 and the adjusting slide 14 are connected by a detection spring 190. The detection slide 19 is always inclined to move towards the adjusting slide 14 under the elastic force of the detection spring 190. The detection slide 19 is hingedly provided with a detection rod 20. The detection rod 20 is located above the gear 17, and the bottom of the detection rod 20 is provided with a triangular tooth, as shown in Figure 11 When the detection rod 20 is in a horizontal state, the triangular tooth at the bottom of the detection rod 20 abuts against the outside of the gear 17. The advantage of the triangular tooth is that when the gear 17 rotates, the outer tooth of the gear 17 abuts against the inclined surface of the triangular tooth, so that the detection rod 20 is inclined to move upward. Correspondingly, the base frame 1 is tightly connected by a bell body 21 through a bolt, as shown in Figure 2 When the adjusting slide 14 moves to the right limit, the upwardly moving detection rod 20 will finally knock the bell body 21 and make the bell body 21 emit a sound.

[0040] As shown in Figure 2 and Figure 4As shown, the end of the base frame 1 has a press bar 27 connected by bolt fastening, and the press bar 27 is above the detection rod 20, and correspondingly, the middle of the detection rod 20 is provided with an arc-shaped protrusion, when the arc-shaped protrusion is away from the press bar 27, the rotation of the gear 17 can make the detection rod 20 deflect upward, when the arc-shaped protrusion is close to the press bar 27 and below the press bar 27, the press bar 27 will limit the upward deflection of the detection rod 20, and when the gear 17 rotates, the detection rod 20 has a tendency to push the detection slide 19 to compress the detection spring 190. On this basis, combined with Figure 1 、 Figure 4 and Figure 6 It can be seen that the side of the upper wedge-shaped sliding block 12 is fixedly connected with a limiting strip 120, as mentioned above, when the support top frame 9 is pressed downward, the zipper element 26 will be clamped and tensioned by the driven roller 25 and the driven pressure wheel 250, if the zipper element 26 is not tensioned during this process, the detection rod 20 will block the downward movement of the limiting strip 120, ensuring that the upper cutter 11 will not be cut when the zipper element 26 is not tensioned.

[0041] Specifically, in the normal state, the protective baffle 2 is pushed by the fastening push spring 3 to drive the protective bottom plate 201 to resist to the lower side of the base frame 1, because the two are close, the reset sliding groove 202 pushes the reset top rod 7 to move upward, the reset top rod 7 drives the material pressing seat 5 to move upward and compresses the material pressing spring 500, finally, the reset top rod 7 moves to the upper side of the reset sliding groove 202, and the limiting top rod 6 moves along the limiting sliding groove 103 to the upper side of the blocking rod 15. The air pump makes the air rod on the air cylinder 8 move upward to force the push plate seat 10 to move away from the starting switch 13 fixed on the top of the base frame 1, at this time, the starting switch 13 is in the on state, and the photoelectric sensor 23 is also in the on state. In detail, when the starting switch 13 and the photoelectric sensor 23 are in the working state at the same time, the motor 16 can be started. The adjusting slide 14 pushes the blocking rod 15 to the buffer cavity 100 under the push of the adjusting spring 140, and during this process, the transition inclined part 151 is below the limiting top rod 6.

[0042] The zipper element 26 is placed between the driven roller 25 and the driven pressure wheel 250. Because the air rod on the air cylinder 8 pushes the push plate seat 10 away from the starting switch 13, and the photoelectric sensor 23 above is also not blocked by the zipper element 26, therefore, the photoelectric sensor 23 and the starting switch 13 are both in the on state, after the data is transmitted to the control computer 4, the control computer 4 forces the motor 16 to start, and uses the motor 16 to drive the driven roller 25 to rotate counterclockwise (the direction is referred to Figure 6 ), and then makes the zipper element 26 forward. The zipper element 26 is supported by the protective bottom plate 201, and guided by the side of the base frame 1 and the protective baffle 2, forcing the zipper element 26 to move forward continuously.

[0043] When the zipper 26 moves above the photoelectric sensor 23, the photoelectric sensor 23 is blocked by the zipper 26 and is in an open state. The control computer 4 processes the data to stop the motor 16 from rotating. Moreover, due to the gravity of the detection rod 20, the triangular teeth are pressed against the outside of the gear 17, thereby restricting the rotation of the gear 17. This, in turn, synchronously restricts the rotation of the driven pressure roller 250, thus preventing the driven pressure roller 250 from rotating freely and forcing the zipper 26 to be over-released when the motor 16 stops working.

[0044] Afterwards, when motor 16 stops working, control computer 4 controls air pump to retract cylinder 8, which in turn moves support top frame 9 downwards synchronously. During this process, support top frame 9 descends and first presses down on the outer side of protective baffle 2. When the trapezoidal protrusion on the outer side of support top frame 9 contacts protective baffle 2, it will push protective baffle 2 away from base frame 1. When protective baffle 2 moves reset slide 202 away from base frame 1, pressure seat 5 moves downwards under the force of pressure spring 500. Limiting top rod 6 moves downwards along transition slope 151 to limiting slide 103. Reset top rod 7 descends along reset slide 202 until pressure seat 5 and base frame 1 press down zipper 26. During this process, because the protective base plate 201 is pressed against the bottom of the base frame 1, driven by the friction between the two, the protective base plate 201 will not move with the protective baffle 2. Therefore, the protective base plate 201 ensures that the zipper component 26 will not move when the base frame 1 and the pressure seat 5 press against it. Subsequently, as the trapezoidal protrusion continuously pushes the protective baffle 2 away from the base frame 1, the protective baffle 2 will eventually also drive the protective base plate 201 to move away from the base frame 1 until the protective base plate 201 is far away from the zipper component 26, thus making the bottom of the zipper component 26 relatively suspended.

[0045] After the pressure seat 5 and the base frame 1 press down on the zipper component 26, the continuing downward-moving upper wedge-shaped slider 12 will approach the lower wedge-shaped slider 18. The lower wedge-shaped slider 18, pushed by the upper wedge-shaped slider 12, will cause the adjusting slide 14 to compress the adjusting spring 140, thus compressing the adjusting spring 140. When the adjusting slide 14 compresses the adjusting spring 140, the adjusting slide 14 will drive the drive roller 25 and the driven pressure roller 250 to tighten the zipper component 26. Figure 2 As shown, as the adjusting slide 14 moves to the left, the zipper 26 is further tightened. If the zipper 26 is not tightened, as the adjusting slide 14 moves, the arc-shaped protrusion on the detection rod 20 enters below the pressure rod 27. As the upper wedge-shaped slider 12 moves downward, the limiting strip 120 on the upper wedge-shaped slider 12 will abut against the detection rod 20. The detection rod 20 blocks and restricts the downward movement of the upper wedge-shaped slider 12, thereby forcing the upper cutter 11 and the lower cutter 22 to be unable to cut the zipper 26, thus avoiding the problem of inconsistent lengths caused by cutting the zipper 26 when it is not tightened.

[0046] Similarly, if the zipper element 26 is in a tension state at this time, as the adjustment slide 14 moves towards the adjustment spring 140, the end of the zipper element 26 is pressed by the pressing seat 5 and the base frame 1 and cannot move, and when the driven pressure roller 250 and the driving roller 25 further tension the zipper element 26, the driving roller 25 and the driven pressure roller 250 will relatively rotate, the gear 17 will rotate counterclockwise, as shown in Figure 2 The gear 17 rotates to make the external teeth abut the triangular teeth at the bottom of the detection rod 20. Since the arc-shaped protrusion above the detection rod 20 is blocked by the pressing rod 27, the detection rod 20 cannot be deflected upward, and thus the rotating gear 17 will push the detection slide 19 and compress the detection spring 190 by using the detection rod 20. When the detection rod 20 moves towards the detection spring 190, it will be relatively misaligned with the limiting bar 120.

[0047] As the upper wedge-shaped slide 12 descends without obstruction, the push plate seat 10 drives the upper cutter 11 to synchronously descend, and the upper cutter 11 and the lower cutter 22 cut the zipper element 26. It should be noted that, as shown in Figure 6 and Figure 7 The adjusting slide 14 is fixedly installed with a material receiving baffle 24 above the lower cutter 22, and when the adjusting slide 14 moves away from the lower cutter 22, the material receiving baffle 24 can support the zipper element 26 to avoid the cut zipper element 26 from falling from the gap between the lower cutter 22 and the driving roller 25 due to gravity. After the upper cutter 11 and the lower cutter 22 cut, the zipper element 26 will fall from below the base frame 1, but the base frame 1 and the pressing seat 5 still clamp the end of the zipper element 26.

[0048] As the supporting top frame 9 continuously descends, when the trapezoidal protrusion passes the protective baffle 2, the protective baffle 2 is pushed by the fastening push spring 3 to move towards the base frame 1, and the reset top rod 7 is pushed by the reset slide groove 202 to move upwards until the pressing seat 5 ascends and forces the limiting top rod 6 to move above the blocking rod 15 again. Since the blocking rod 15 has moved with the adjusting slide 14 at this time, the end of the blocking rod 15 has passed the air overflow groove 101 and is away from the air buffering cavity 100, and the limiting top rod 6 is above the side plane of the blocking rod 15 at this time, and the limiting top rod 6 is limited from descending by the side plane of the blocking rod 15, that is, the pressing seat 5 is relatively away from the base frame 1.

[0049] Afterwards, the air pump will push the air rod in the cylinder 8 upwards, making the support top frame 9 move upwards, the trapezoidal block will contact the protective baffle 2 again, forcing the protective baffle 2 to open again, but at this time the pressure seat 5 cannot descend due to the limiting of the top rod 6 against the side plane of the baffle 15, so when the base frame 1 and the protective baffle 2 open again, the cut-off zipper part 26 falls from the bottom of the base frame 1 and the protective baffle 2. Generally, a storage box or a conveying belt is placed at the bottom of the base frame 1 and the protective baffle 2 to facilitate the processing of the cut-off zipper part 26.

[0050] When the support top frame 9 pulls the push plate seat 10 and the upper wedge-shaped slider 12 to continuously move upwards, the upper wedge-shaped slider 12 will eventually move away from the lower wedge-shaped slider 18 until the upper wedge-shaped slider 12 and the lower wedge-shaped slider 18 are separated. Afterwards, the adjusting slide 14 moves again in the direction away from the adjusting spring 140 under the elastic pushing of the adjusting spring 140, and the arc-shaped protrusion on the detection rod 20 will also move away from the pressing rod 27. The baffle 15 moving with the adjusting slide 14 will also pass through the air overflow groove 101 and enter the air buffering cavity 100.

[0051] When the push plate seat 10 is completely raised, the start switch 13 is also released, and there is no zipper part 26 on the photoelectric sensor 23, so the motor 16 will work again and transport the zipper part 26 again to the direction of the photoelectric sensor 23. When the zipper part 26 reaches the top of the photoelectric sensor 23 again, the tension detection and cutting of the zipper part 26 are completed again according to the above content.

[0052] When the driving roller 25 and the driven pressure roller 250 are outputting the zipper part 26, the adjusting slide 14 still causes the baffle 15 to press the air buffering cavity 100 under the pushing of the adjusting spring 140, and the air in the air buffering cavity 100 slowly flows out from the damping hole 102. If the baffle 15 completely squeezes out the air in the air buffering cavity 100, and the zipper part 26 has not reached the top of the photoelectric sensor 23, it means that there is a material breakage between the driving roller 25 and the driven pressure roller 250 or the zipper part 26 is not normally transported between the base frame 1 and the protective baffle 2. In combination Figure 2 When the adjusting slide 14 moves to the right limit, the detection rod 20 is located below the bell body 21, and since the motor 16 drives the driving roller 25 to rotate, the driving roller 25 and the driven pressure roller 250 are always tightly pressed together due to the rubber material, so the driven pressure roller 250 rotates synchronously with the gear 17. When the outer teeth of the rotating gear 17 pass through the triangular teeth, since the arc-shaped protrusion on the detection rod 20 is not restricted, the detection rod 20 moves upwards and continuously hits the bell body 21, and the bell body 21 continuously emits sound to alert external personnel that this place needs to be maintained.
