Description

Technical Field

[0001] The invention belongs to the field of zipper machines and relates to a highly efficient and stable oblique-mouth threading and zipping all-in-one machine. Technical Background

[0002] Now the beveled upper slider process can form the upper stop and the lower stop at one time, and then form the bevel on the chain splitter upper stop with a square, and complete the upper slider work through the beveled mouth, reducing the process steps and the length of the production line. Therefore, the beveled chain threading machine is becoming more and more popular in the market.

[0003] Chinese invention patent CN2023115975287, the patent name is a chain threading and chain connecting integrated machine with a chain upper stop and an oblique mouth, which discloses that the chain position is positioned by a block sensing mechanism, and then the side of the upper stop positioning clamp will abut against the rear end surface of the upper stop, and move the upper stop forward to the set position, thereby positioning the upper stop position, indirectly positioning the oblique mouth position of the upper stop, and then the upper slider mold rises, the positioning clamp is to position the oblique mouth of the upper stop to the side of the slider of the slider mold, and then the rotating drive mechanism rotates the slider mold to a certain angle, so that the inlet of the slider is aligned with the oblique mouth, and then the push block drive device pushes the oblique mouth of the upper stop into the slider, and then the rear pull The guiding device controls the chain belt to retreat so that the pull head enters the block chain to complete the chain threading, and then the chain belt continues to retreat. When the block enters the block fixing groove, the positioning block of the block positioning device fixes the block, and the clamping wheel lifting device controls the clamping wheel of the corresponding block chain to lift. The traction wheel drives the latch chain to retreat alone, so that the latch retreats to the rear side of the block, and the latch chain moving plate is used to move the latch chain up, down, left and right, so that the latch is aligned with the sockets of the block and the pull head, and then the aligned latch is inserted into the socket through the front traction device, and then the chain belt is pulled forward through the front traction device to realize the chain paralleling process, thereby realizing automated production and improving production efficiency.

[0004] Although the device can automatically thread and parallelize the chain belt with the upper stop bevel, the device has the following four problems: 1. The block sensing mechanism and the block positioning device of the device are two separate mechanisms, resulting in a complex structure, large space occupation and high cost; 2. Since the upper stop positioning mechanism actively moves and positions the upper stop position, it is impossible to detect whether an upper stop is formed on the block chain; 3. Since the front and rear driving forces of the latch chain are both from the traction wheel, the traction wheel is also the driving force for the chain belt traction. After the front traction wheel inserts the latch into the pull head and the block, the front traction wheel drives the block chain and the latch chain to move simultaneously to complete the parallel connection. At this time, the latch is often not inserted to the bottom, affecting the stability of production; 4. Since the device needs to complete all the parallel connections of the previous pull head before it can thread the chain of the next pull head, the efficiency is low. Summary of the invention

DETAILED DESCRIPTION

[0038] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0039] A highly efficient and stable oblique-mouth threading and combining machine, comprising a chain belt traction mechanism 1 and a chain belt platform 11 arranged on a frame 0, the chain belt platform 11 is divided into a block chain channel 12 and a latch chain channel 13, the block chain channel 12 is provided with a block fixing induction mechanism 2, an upper stop side pushing mechanism 4 and an upper stop positioning mechanism 3 are arranged in front of the block fixing induction mechanism 2, an upper slider mold 5 which can fix and transport the slider to a position is arranged below the upper stop positioning mechanism 3, the upper slider mold 5 is moved to a set position after the upper stop is positioned by the upper stop positioning mechanism 3, the upper stop side pushing mechanism 4 is arranged on the side of the upper slider mold 5, the push block 41 on the upper stop side pushing mechanism 4 pushes the oblique mouth on the upper stop 105 into the chain inlet of the slider 109, the front opening of the slider is the chain inlet, and the rear opening of the slider is the slider socket 110;

[0040] A latch chain lowering plate 61 and a lowering cylinder 62 for driving the latch chain lowering plate to move up and down are provided in front of the latch chain channel 13. A latch chain slot 63 is formed on the latch chain lowering plate 61. The latch chain slot 63 includes a chain tooth slide groove and a chain belt slide groove. A latch chain forward clamp 64 and a forward drive for driving the latch chain forward clamp to move forward are provided in front of the latch chain lowering plate 61. A latch chain two-stage backward movement mechanism 7 is provided at the rear of the latch chain channel 13. A long parallel mechanism 9 is also provided between the latch chain lowering plate 61 and the latch chain forward clamp 64. A block chain auxiliary mechanism 8 is provided at the rear of the block chain channel.

[0041] The block fixing induction mechanism 2 comprises a fixed cylinder 21, a moving seat 22, a swing rod 23, a swing cylinder 24, an induction fixing strip 25, an induction switch 26 and a compression reset spring 27. The protruding end of the fixed cylinder 21 fixed on the frame protrudes forward and is fixedly connected to the moving seat 22. A transverse groove 221 for the swing rod to swing is formed in the moving seat 22. The swing rod 23 is rotatably arranged in the transverse groove 221 through a pin shaft 222. A swing cylinder 24 is arranged on the moving seat 22. The protruding end of the swing cylinder 24 protrudes downward and presses against the moving seat 22. At the rear end of the swing rod 23, a compression return spring 26 is also provided at the upper end of the front end of the swing rod 23. The compression return spring 26 always gives a downward force to the front end of the swing rod 23. The front end of the swing rod 23 is fixedly connected to the induction fixing bar 25. A fixing groove 28 matching the block is formed in front of the lower end of the induction fixing bar 25. The rear of the lower end of the induction fixing bar 25 is an arc-shaped induction part 29. The arc-shaped induction part 29 is arranged on the path of the block. The frame is also provided with an induction switch 26 for detecting the position of the induction fixing bar 25.

[0042] Through the above arrangement, when the block 103 passes through the induction fixing bar 25 and lifts it, and then quickly resets under the action of the compression reset spring 27, the induction switch 26 obtains a short signal, at which time the upper stop positioning clip 31 is controlled to extend to position the upper stop 105, and at the same time the long parallel mechanism is controlled to complete the parallel connection of the remaining chain belts for the chain belts that have completed a small part of the parallel connection in front;

[0043] After the slider is threaded through the chain, the chain belt keeps moving forward to move the block 103 to the block fixing groove 51 behind the slider, and the extended end of the fixed cylinder 21 extends forward, driving the inductive fixing bar 25 to move forward, so that the fixing groove 28 on the inductive fixing bar 25 just presses against the block 103, thereby fixing the block. After the latch 104 is inserted into the slider 109 and the block 103, the extended end of the swing cylinder 24 extends out, the inductive fixing bar 25 moves upward, and the extended end of the fixed cylinder 21 retracts, the inductive fixing bar 25 loses the fixation of the block 103, and the block can retreat from the opening of the block fixing groove 51, so that the block 103 and the slider 109 are separated by a distance to achieve a short distance of parallel connection. When the two-stage backward movement mechanism 7 completes the short distance of parallel connection, the extended end of the swing cylinder 24 retracts, and the inductive fixing bar 25 moves downward and resets under the action of the compression reset spring 27.

[0044] The latch chain two-stage backward movement mechanism 7 includes a latch chain retracting clamp 71 arranged at the rear of the latch chain channel 13, a first-stage latch cylinder 72 and a second-stage parallel cylinder 73 for driving the latch chain retracting clamp to move backward, the second-stage parallel cylinder 73 is arranged at the rear of the latch chain retracting clamp 71 and fixed on the frame 0, the protruding end of the second-stage parallel cylinder 73 extends forward and is connected with a slide seat 74, the slide seat 74 is slidably arranged on a slide rail 75, the first-stage latch cylinder 72 is fixed on the slide seat 74, the protruding end of the first-stage latch cylinder 72 extends forward and is fixedly connected to the latch chain retracting clamp 71, and the latch chain retracting clamp 71 is slidably arranged on the slide rail 75. Through the above arrangement, the latch chain forward clamp 64 drives the latch chain 102 forward, so that the latch 104 moves to the upper front of the slider socket 110, and the latch chain lowering plate 61 moves downward to move the latch to the front of the slider socket 110, and then the latch chain retracting clamp 71, driven by a first-stage latch cylinder 72, inserts the latch 104 into the slider 109 and the block 103. At this time, regardless of whether the latch 104 is inserted to the bottom or not, since the latch chain retracting clamp 71 is clamped separately on the latch chain 102, when the second-stage parallel cylinder 73 drives the latch chain to retreat to complete the parallel connection, it can ensure that the latch 104 is inserted to the bottom and then the parallel connection is completed, thereby improving the stability of the latch being inserted to the bottom and improving the stability of the overall production.

[0045] The block chain auxiliary mechanism 8 includes a block chain auxiliary clamp 81 arranged at the rear of the block chain channel 12, and a tension spring (not shown) is connected to the block chain auxiliary clamp 81. The tension spring always gives the block chain auxiliary clamp 81 a force to move backward. An auxiliary clamp reset cylinder 82 is also arranged at the rear of the block chain auxiliary clamp 81, and the extended end of the auxiliary clamp reset cylinder 82 extends forward and abuts against the rear end of the block chain auxiliary clamp 81. Through the arrangement of the block chain auxiliary clamp 81 and the tension spring, when the latch chain retreat clamp 71 drives the latch chain 102 to retreat, the tension spring drives the block chain auxiliary clamp 81 to clamp the block chain 101 to retreat, so that the front chain belt can be in a straightened state, preventing the block chain 101 from being loose and interfering with the latch chain 102 or other mechanisms, thereby improving the overall production stability.

[0046] The long parallel mechanism includes a long parallel clamp 91, a left and right cylinder 93 for driving the long parallel clamp to move left and right, and a long parallel drive for driving the long parallel clamp to move forward and backward. A parallel groove 92 is formed on the long parallel clamp 91. Through the above arrangement, the parallel connection is divided into two independent sections, which has two advantages: 1. After the second-section parallel cylinder 73 drives the latch chain back clamp to complete the short-distance parallel connection, the long parallel device is used to complete the parallel connection of the remaining unconnected parts. Dividing the parallel connection into two sections can shorten the length of the second-section backward movement mechanism station; 2. After completing the first section of short-distance parallel connection, the second section of long-distance parallel connection is realized by the movement of the long parallel clamp 91. At this time, the chain belt needs to be fixed, so it is just carried out at the same time as the chain threading action of the next pull head. Therefore, when the block sensing fixing mechanism 2 senses the block 103, it controls the upper stop positioning mechanism 3 and the long parallel mechanism to work at the same time, thereby increasing work efficiency.

[0047] The long parallel clamp 91 is fixed on the protruding ends of the left and right cylinders, the left and right cylinders are fixed on the slide 94, the latch chain forward clamp 64 is also fixed on the slide 94, the slide 94 is slidably set on the linear module 95, and the long parallel drive of the long parallel clamp 91 and the forward drive of the latch chain forward clamp are both linear modules 95.

[0048] The upper stop positioning mechanism 3 includes an upper stop positioning clamp 31 arranged in front of the block chain belt channel and a clamping cylinder 32 for driving the upper stop positioning clamp to open or close. The upper stop positioning clamp 31 is formed with a chain splitting channel 33, and the chain splitting channel 33 includes a sprocket channel 331 and a belt channel 332. The width of the sprocket 108 is less than the width of the sprocket channel 331 and the width of the upper stop 105.

[0049] The upper stop positioning mechanism 3 also includes a guide rail 34 arranged on the frame, the guide rail 34 is parallel to the chain belt channel, a slider 35 is slidably arranged on the guide rail 34, a connecting plate 36 is fixed on the slider 35, a telescopic cylinder 37 is fixed on the connecting plate 36, the output end of the telescopic cylinder 37 is fixedly connected to the clamping cylinder 32, and the telescopic direction of the output end of the telescopic cylinder is perpendicular to the direction of the guide rail 34;

[0050] A tension spring 38 is also connected between the connecting plate 36 and the frame, and the tension spring 38 always gives the connecting plate 36 a force to move backward;

[0051] The frame is also provided with an upper stop positioning mechanism position detection plate 39; the frame is also provided with an upper stop positioning mechanism positioning cylinder 310. When the detection plate 39 detects that the upper stop positioning clamp 31 reaches the set position, the protruding end of the positioning cylinder 310 is controlled to extend forward and press against the upper stop positioning mechanism to prevent the connecting plate 36 from retreating; if the detection plate 39 does not detect the upper stop positioning clamp 31 reaching the set position signal within the set time, the control device stops operating.

[0052] By forming a sprocket channel 331 on the upper stop positioning clamp 31, and setting the width of the sprocket 108 less than the width of the sprocket channel 331 less than the width of the upper stop 105, when the chain belt has the upper stop 105 in a normal state, after the induction fixing strip 25 detects the block 103, the upper stop positioning clamp 31 extends and closes in the transition section 107 without sprockets, and the chain belt traction device 1 pulls the chain belt to continue to move forward. Since the width of the upper stop 105 is greater than the width of the sprocket channel 331 in the upper stop positioning clamp, and the positioning clamp 31 is fixed on the connecting plate 36, the front end of the upper stop 105 moves forward together with the side of the upper stop positioning clamp 31 until the detection plate 39 detects the signal that the upper stop positioning mechanism reaches the set position, and then controls the positioning cylinder 310 to extend and press against the upper stop positioning mechanism to prevent the connecting plate 36 from being pulled back by the tension spring 38, and then completes the subsequent upper pull head action;

[0053] If the upper stop 105 of the chain belt falls off, after the sensing fixing strip 25 detects the block 103, the upper stop positioning clip 31 extends out and closes in the transition section 107, and the chain belt continues to move forward. However, since there is no upper stop and the sprocket channel 331 on the positioning clip 31 is larger than the width of the sprocket 108, the sprocket 108 on the chain belt passes directly through the sprocket channel 331 and cannot move forward with the positioning clip 31. Therefore, if the detection plate 36 does not detect that the upper stop positioning mechanism is in place within the set time, it is determined that there is no upper stop on the chain belt, and then the equipment is controlled to stop running to prevent equipment damage.

[0054] The extended end of the telescopic cylinder 37 is connected to the first guide seat 311 , a first slideway 312 matching the first guide seat 311 is fixed on the connecting plate 36 , and the clamping cylinder 32 is fixedly connected to the first guide seat 311 .

[0055] The top stop side thrust mechanism 4 includes a push block 41 disposed behind the top stop positioning clamp 31 and a push block cylinder 42 for driving the push block to move left and right. The push block cylinder 42 is fixedly connected to the connecting plate 36 .

[0056] The protruding end of the push block cylinder 42 is connected to a second guide seat 43 , a second slideway 44 matching the second guide seat 43 is fixed on the connecting plate 36 , and the push block 41 is fixedly connected to the second guide seat 43 .

[0057] The upper end surface of the upper slider mold 5 has a slider fixing groove 52 and a block fixing groove 51 . The rear of the block fixing groove 51 is open. The induction fixing strip 25 abuts against the rear of the block from the open position to fix the block 105 .

[0058] Working principle:

[0059] When the chain belt enters the device, it is in a split chain state. The block chain 101 with the upper stop 105 with the oblique mouth 106 goes through the block chain belt channel 12, and the latch chain 102 goes through the latch chain belt channel 13. The block chain belt channel 12 is provided with an induction fixing strip 25. The chain belt moves under the traction of the traction device. When the block passes through the induction fixing strip 25 and lifts it up, and then quickly resets it under the action of the compression reset spring 27, the induction switch 26 gets a short signal. After the induction switch detects the short signal, it controls the telescopic cylinder 37 to extend the upper stop positioning clamp 31 and then controls the clamp The holding cylinder 32 closes the upper stop positioning clip 31 in the transition section 107 without sprockets, and the chain belt traction device pulls the chain belt to continue to move forward. Since the width of the upper stop 105 is greater than the width of the sprocket channel 331 in the upper stop positioning clip 31, and the positioning clip 31 is fixed on the connecting plate 36, the front end of the upper stop 105 pushes against the rear end surface of the upper stop positioning clip 31 and moves forward together until the detection plate 39 detects the signal that the upper stop positioning mechanism reaches the set position, and then controls the positioning cylinder 310 to extend and push against the upper stop positioning mechanism to prevent the connecting plate 36 from being pulled back by the tension spring 38;

[0060] Then the telescopic cylinder 37 controls the upper stop positioning clamp 31 to retract, pulling the block chain 101 and the pin chain 102 to create a gap for installing the slider, and then the upper slider mold 5 moves up to position the chain inlet 111 of the slider to the side of the upper stop bevel 106, and then the upper stop positioning clamp 31 is released, and the push block 41 pushes the upper stop bevel 106 to the chain inlet 111 of the slider, so that the chain belt continues to move forward under the traction device, and the slider is fixed by the upper slider mold 5, and the block 103 on the chain belt moves until it reaches the block fixing groove 51 to complete the action of the upper slider.

[0061] Then the chain belt traction device drives the chain belt forward, so that the block moves into the block fixing groove 51 behind the pull head, and the extended end of the fixing cylinder 21 extends forward, driving the induction fixing bar 25 to move forward, so that the fixing groove 28 on the induction fixing bar 25 just presses on the block 103, thereby fixing the block.

[0062] Then the bolt chain forward moving clamp 64 clamps the bolt chain 102 and drives the bolt chain to move forward a short distance, so that the bolt 104 moves forward to the front upper part of the slider socket 110, and then the bolt chain lowering plate 61 drives the bolt to move downward, so that the bolt is located in front of the slider socket 110, and then the first-stage bolt cylinder 72 drives the bolt chain backward clamp 71 to clamp the bolt chain and retreat a short distance, so that the bolt 104 is inserted into the slider 109 and the block 103. Then the swing cylinder 24 extends to make the induction fixing bar 25 move upward to release the fixation of the block, and the second-stage parallel cylinder 73 drives the bolt chain backward clamp 71 to clamp the bolt chain 102 and retreat a distance for the second time. Since the slider is still fixed by the slider fixing groove 52 on the upper slider mold 5 at this time, the bolt and the block are pulled away from the slider by one end, completing the parallel connection of a short distance.

[0063] When the latch chain retracting clamp 71 clamps the latch chain, the block chain auxiliary clamp 81 clamps the block chain 101. When the latch chain retracting clamp 71 drives the latch chain 102 to retreat, the protruding end of the auxiliary clamp reset cylinder 82 retracts, and the tension spring drives the block chain auxiliary clamp 81 to retreat with the block chain, so that the chain belt in front can be in a straightened state.

[0064] Then the latch chain retracting clamp 71 and the block chain auxiliary clamp 81 are both opened, the upper slider mold 5 moves down and loses its fixation on the slider, the swing cylinder 24 retracts the induction fixing bar 25, and the compression reset spring 27 moves downward and resets, and the chain belt moves forward under the action of the traction mechanism. When the next block goes under the induction fixing bar 25, the slider that has completed the partial parallel connection goes in front of the long parallel clamp 91. At this time, the induction switch 26 senses the short signal again to control the upper stop positioning mechanism to position the upper stop and complete the corresponding slider chain threading action, and the long parallel clamp 91 extends toward the chain belt, and the parallel slot 911 on the long parallel clamp 91 is against the rear of the slider, and then the long parallel clamp 91 moves forward to drive the slider to complete the parallel connection of the remaining long distance of the unconnected part, thereby realizing the simultaneous chain threading and parallel connection, thereby increasing production efficiency.

[0065] The invention has the characteristics of simple structure, high efficiency and stability.
