Description

Technical Field

[0001] The invention belongs to the field of zipper machines, and relates to a high-speed threading and assembling machine for formed upper and lower stop zippers. Technical Background

[0002] The traditional chain belt molding process is: 1. Injection molding the chain teeth for the cloth bag; 2. Molding the bottom stop for the chain belt; 3. Then complete the chain threading and parallel connection; 4. Finally, injection molding the top stop. The reason for molding the top stop last is that if the top stop is molded first, the slider cannot be inserted, so the slider can only be inserted first, and then the top stop is molded.

[0003] This method has a long process, large equipment space and low production efficiency. In order to solve this problem, China Invention Patent ZL2023115975287, the patent name is a chain belt upper stop belt beveled chain threading and chain connecting integrated machine, which discloses positioning the chain belt position through a block sensing mechanism, and then moving the upper stop positioning clamp to a fixed position through the mobile drive device of the upper stop positioning clamp. The side of the upper stop positioning clamp will abut against the rear end face of the upper stop, and move the upper stop forward to the set position, indirectly positioning the upper stop bevel position, and then rising through the upper slider mold, the positioning clamp is to position the upper stop bevel to the slider side of the slider mold, and then the push block drive device pushes the upper stop bevel into the slider , then the rear traction 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 fixed groove, the pressure wheel lifting device controls the pressure wheel of the corresponding block chain to lift, and 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 this method can automatically thread and connect the zippers with upper and lower stops, the process is still complicated and the production efficiency is not high enough. Summary of the invention

The belt-passing channel includes a sprocket channel and a cloth belt channel. A positioning pin and a positioning pin driving mechanism driving the positioning pin to move up and down are arranged on the sprocket channel. After the positioning pin is extended, the sprocket channel is only large enough for the sprocket to pass through but not for the upper stop to pass through.

[0009] The double positioning mechanism also includes a linear rail fixed on the bracket, the linear rail and the chain belt moving direction are parallel, the slide seat is slidably arranged on the linear rail, the frame is also provided with a tension spring, the tension spring is connected to the slide seat and always gives the slide seat a pulling force to pull backward, and the rear of the slide seat is also provided with an upper stop positioning cylinder and a block positioning cylinder; the outer side of the slide seat is also fixed with a detection baffle, and the frame is provided with an induction switch plate corresponding to the detection baffle, when the induction switch plate cannot sense the detection baffle, the protruding end of the upper stop positioning cylinder is controlled to extend and abut against the rear side of the slide seat; when the block sensing mechanism senses the block, the block moves to the rear of the pulling head, and the block sensing mechanism delays the control of the belt plate cylinder to extend and controls the block positioning cylinder to extend, so that the positioning seat abuts against the rear end face of the block to fix the block;

[0011] Through the setting of the stop pin, when the pin chain side pushing device pushes the pin chain into the pull head, the stop pin blocks the chain belt behind the pin to prevent the chain belt from following the pin into the pull head and getting stuck, or the pin cannot be inserted into place; in this way, the pin chain side pushing device does not need to rise and fall processes, which greatly improves the production speed.

[0012] The present invention is further configured as follows: the extending end of the needle stopper cylinder extends upward and is fixed with a needle stopper seat, the needle stopper is rotatably arranged on the needle stopper seat, the lower end of the needle stopper is also provided with a sensing strip, and a sensing strip sensing switch is fixed on the upper pull head mold.

[0013] Through the above settings, the pin chain side pushing device pushes the pin sideways to the rear of the pull head socket, and then the pin chain retreat device drives the pin chain retreat to insert the pin into the socket; at this time, the pin chain retreats to drive the stop pin to swing, and the induction switch senses the swing of the induction bar, then controls the stop pin cylinder to retract the stop pin to its original position.

[0015] Through the above arrangement, after the stopper needle is raised, it will always rotate forward due to the center of gravity without external force, so the stopper needle and the positioning block will counteract each other, so that the stopper needle can maintain a stable state.

[0016] The present invention is further configured as follows: a limited rotation shaft is fixed on the stopper needle, the limited rotation shaft is arranged above the stopper needle seat, and the upper end portion of the stopper needle seat is the limited rotation portion.

[0017] The setting of the rotation limiting shaft can prevent the belt from deviating too much at an angle when the blocking needle is chained and retracted by the latch pin, thereby affecting the resetting of the blocking needle.

[0018] The present invention is further configured as follows: the induction switch is arranged below the stopper needle, the upper end surface of the induction switch is a plane, the lower end surface of the stopper needle is a plane, and when the stopper needle cylinder retracts, the two planes fit together, causing the stopper needle to rotate and return to a vertical state.

[0022] Arranging the positioning pin and its rotating mechanism in the positioning seat can make the structure more stable. The movement of the positioning pin is guided by the vertical groove. Since the chain belt is soft after all, it moves up and down a lot during operation. After moving up, the positioning pin can be retracted into the positioning seat and is not easy to interfere with the chain belt.

[0024] Through the above arrangement, the belt-passing plate cylinder is extended and retracted to drive the slide plate to slide on the slide seat. The belt-passing plate and the positioning seat are both arranged on the slide plate. Therefore, the belt-passing plate and the positioning seat slide under the drive of the belt-passing plate cylinder to achieve left and right movement. After the positioning pin in the positioning seat is controlled to come down, the cloth belt pulling surface of the positioning pin is against the inner side of the cloth belt in front of the upper stop straight code, and then the belt-passing plate cylinder drives the positioning seat to move outward, and the positioning pin in the positioning seat pulls the chain belt open a hole to allow the pull head to come up

[0050] 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.

[0051] A high-speed threading and assembling machine for forming upper and lower stop zippers, comprising a chain belt guide platform 11 and a chain belt traction mechanism 14 arranged on a frame 1, wherein the chain belt guide platform 11 is respectively provided with a block chain belt channel 12 and a latch chain belt channel 13, and the block chain belt channel 12 is provided with a block sensing mechanism 15, and an upper pull head device 4 is provided in front of the block sensing mechanism 15, and an upper stop and block double positioning mechanism 2 and an upper stop side pushing mechanism 3 are provided on the side of the upper pull head device 3 close to the block chain; a latch chain advancing device 6 is provided in front of the latch chain belt channel 13, and a latch chain retreating device 8 is provided at the rear of the latch chain belt channel, and a latch chain side pushing device 7 is provided on the side of the upper pull head device 4 close to the latch chain;

[0052] The upper stop and block dual positioning mechanism 2 includes a slide 21, a belt-passing plate 22 slidably arranged on the slide 21, and a belt-passing plate cylinder 23 for driving the belt-passing plate 22 to move left and right. A positioning seat 24 is provided on the belt-passing plate 22, and a belt-passing channel is formed between the belt-passing plate 22 and the positioning seat 24. The belt-passing channel includes a sprocket channel 25 and a cloth belt channel 26. A positioning pin 27 and a positioning pin driving mechanism for driving the positioning pin to move up and down are provided on the sprocket channel 25. After the positioning pin 27 is extended, the sprocket channel 25 is only large enough for the sprocket to pass through but not for the upper stop.

[0053] The double positioning mechanism also includes a linear rail 28 fixed on the bracket, the linear rail 28 is parallel to the moving direction of the chain belt, the slide 21 is slidably arranged on the linear rail 28, the frame 1 is also provided with a tension spring (not shown), the tension spring is connected to the slide 21 and always gives the slide 21 a pulling force to pull backward, the rear of the slide 21 is also provided with an upper stop positioning cylinder 29 and a block positioning cylinder 210; the outer side of the slide 21 is also fixed with a detection baffle 211, the corresponding The detection baffle 211 is provided with an induction switch plate 212. When the induction switch plate 212 cannot sense the detection baffle 211, the extended end of the upper stop positioning cylinder 29 is controlled to extend and abut against the rear side of the slide seat 21; when the block sensing mechanism 15 senses the block 103, the block moves to the rear of the pull head, and the block sensing mechanism 15 delays the control of the strip plate cylinder 23 to extend and controls the block positioning cylinder 210 to extend, so that the positioning seat 24 abuts against the rear end face of the block to fix the block 103;

[0054] The upper slider device includes an upper slider mold 41, an upper and lower slider cylinder 42 that moves the upper slider mold up and down, and a slider front and rear cylinder 43 that drives the upper slider mold to move forward and backward; a slider fixing position 44 is provided at the upper end of the upper slider mold, and a stopper needle 45 is provided on the side of the upper slider mold 41 facing the pin chain side pushing device, and a stopper needle cylinder 46 that drives the stopper needle to move up and down, and the stopper needle 45 is blocked on the side of the slider fixing position 44.

[0055] Through the setting of the stop needle 45, when the pin chain side pushing device 7 pushes the pin chain 102 into the slider 9, the stop needle 45 blocks the cloth bag behind the pin 104, preventing the cloth bag from following the pin 104 into the slider 9 and causing the cloth bag to get stuck or the pin not being inserted into place; through the design of the stop needle 45, the pin chain side pushing device 7 does not need the rising and falling processes, and can also prevent the cloth belt from getting stuck in the slider, thereby greatly improving the production speed.

[0056] The present invention adopts the design of the positioning pin 27 on the double positioning mechanism. After the positioning pin 27 is extended, the sprocket channel 25 is only large enough for the sprocket 108 to pass through but not the upper stop 105 to pass through. In the normal state of the chain with the upper stop 105, after the block sensing mechanism 15 detects the block 103, the positioning pin 27 is extended, and the chain belt traction device 14 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 25 after the positioning pin 27 is extended, the front end of the upper stop 105 moves forward together with the side of the positioning seat 24 until the sensing switch plate 212 cannot sense the detection baffle 211, and the slide 24 reaches the set position, and then the upper stop positioning cylinder 29 is controlled to extend to support the slide 21 to prevent the slide from being pulled back by the tension spring, and then the subsequent upper pull head action is completed;

[0057] If the upper stop of the chain belt falls off, the block sensing mechanism 15 detects the block 103, the positioning pin 27 extends, and the chain belt continues to move forward. However, since there is no upper stop 105, the sprocket channel 25 after the positioning pin 27 extends is larger than the width of the sprocket 108, so the sprocket on the chain belt passes directly through the sprocket channel and cannot move forward with the positioning seat 24. Therefore, if the sensing switch board does not detect that the slide seat 24 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.

[0058] The double positioning mechanism 2 can also fix the block 103. When the block sensing mechanism senses the block 103, the block 103 moves to the rear of the pull head 9. The block sensing mechanism 15 delays the extension of the belt plate cylinder 23 and controls the extension of the block positioning cylinder 210, so that the positioning seat 24 abuts against the rear end face of the block 103 to fix the block 103. Integrating the upper stop positioning mechanism and the block positioning mechanism together can reduce the size of the equipment.

[0059] The protruding end of the needle stopper cylinder 46 extends upward and is fixed with a needle stopper seat 47, the needle stopper 45 is rotatably arranged on the needle stopper seat 47, the lower end of the needle stopper 45 is also provided with a sensing bar 48, and the upper slider mold is fixed with a sensing bar induction switch 49. Through the above arrangement, the latch pin chain side push device 7 pushes the latch pin to the rear of the slider latch pin opening 91, and then the latch pin chain retreat device 8 drives the latch pin chain to retreat, so that the latch pin 104 is inserted into the slider latch pin opening 91; when the latch pin chain 102 retreats, it drives the needle stopper 45 to swing, and the sensing bar induction switch 49 senses the swing of the sensing bar 48, and then controls the needle stopper cylinder 46 to retract the needle stopper 45 to return to its original position.

[0060] The center of gravity of the stopper needle 45 is arranged in front of the rotation axis, a positioning block 410 is arranged in front of the stopper needle seat 47, and a positioning groove 411 matching the positioning block 410 is formed on the front end surface of the middle part of the stopper needle. Through the above arrangement, after the stopper needle 45 is raised, it always rotates forward due to the center of gravity without external force, so the stopper needle 45 and the positioning block 410 are counteracted, so that the stopper needle 45 can maintain a stable state.

[0061] The stopper needle 45 is also fixed with a limited rotation shaft 412, which is arranged above the stopper needle seat 47, and the upper end of the stopper needle seat is a limited rotation part. The setting of the limited rotation shaft can prevent the stopper needle from being deviated too much when the belt is retracted by the pin chain, thus affecting the reset of the stopper needle.

[0062] The induction switch 49 of the induction strip is arranged below the stopper needle 45. The upper end surface of the induction switch 49 is a plane, and the lower end surface of the stopper needle 45 is a plane. When the stopper needle cylinder 46 retracts, the two planes fit together, so that the stopper needle 45 rotates and returns to a vertical state.

[0063] The lower end of the positioning pin 27 is formed with an "L"-shaped groove, the upper end surface of the "L"-shaped groove is the cloth tape pressing plane, the inner side surface of the "L"-shaped groove is the cloth tape pulling surface, and the rear side surface of the "L"-shaped groove is the upper stop resistance surface. The height of the "L"-shaped groove is less than the height of the chain tooth, and the distance from the cloth tape pulling surface 272 to the inner side surface of the chain tooth channel is less than the width of the chain tooth.

[0064] The positioning needle driving mechanism includes a positioning needle cylinder 213 fixed on the positioning seat 24, the output end of the positioning needle cylinder 213 is rotatably connected to a push rod 214, and the other end of the push rod 214 is rotatably connected to a positioning needle 27. The positioning seat 24 is formed with a vertical groove 215 for the positioning needle to move up and down, and a horizontal groove 216 for the push rod 214 to rotate. A pin shaft 217 is fixed in the horizontal groove 216 and passes through the push rod 214, and the push rod 214 rotates around the pin shaft 217 as the axis.

[0065] A block chain auxiliary clamp 51 and an auxiliary clamp cylinder 52 for driving the auxiliary clamp to open and close are arranged at the rear of the block chain passage. A tension spring (not shown) is connected to the block chain auxiliary clamp 52, which always gives the block chain auxiliary clamp 51 a force to move backward. By setting the block chain auxiliary clamp 51, when the latch chain retreat device 8 drives the latch chain 102 to retreat, the tension spring drives the block chain auxiliary clamp 51 to retreat with the block chain, so that the chain belt in front can be in a straightened state, preventing the block chain from being loose and interfering with the latch chain, thereby improving the overall production stability.

[0066] The latch chain advancing device 6 includes a belt-passing plate 61, a pressure plate 62, a clamping cylinder 63 and a forward power. The forward power of this embodiment and the forward power of the long parallel clamp 66 share a set of linear modules 64. A fixed seat 65 is fixed at the lower end of the belt-passing plate 61, and the clamping cylinder 63 is fixed on the fixed seat 65. The protruding end of the clamping cylinder 63 protrudes upward and is fixedly connected to the pressure plate 62. The fixed seat 65 and the linear module 64 are fixedly connected.

[0067] The latch chain side push device 7 includes a latch push plate 71 and a latch push plate cylinder 72 arranged on the side of the upper slider mold 41. The latch push plate opens toward the upper slider mold, and the opening is a latch chain slot 73 that matches the latch chain.

[0068] The latch chain retraction device 8 includes a retraction cylinder 81, a retraction seat 82, an upper clamping plate 83, a lower clamping plate 84 and a clamping plate cylinder 85. The retraction cylinder 81 is fixed on the bracket 1, and the protruding end of the retraction cylinder 81 is fixedly connected to the retraction seat 82. The lower clamping plate 84 is fixed to the upper end of the retraction seat 82. The clamping plate cylinder 85 is fixed to the lower end of the retraction seat 82. The protruding end of the clamping plate cylinder 85 extends upward and is fixedly connected to the upper clamping plate 83. The clamping plate cylinder 85 drives the upper clamping plate 83 to move up and down and clamps with the lower clamping plate 84.

[0069] The upper stop side thrust mechanism 3 includes an upper stop thrust plate 31 arranged at the rear end of the positioning seat and a side thrust cylinder 32 that drives the upper stop thrust plate to move left and right. The side thrust cylinder 32 is fixed on the slide seat 21. The outer end of the upper stop thrust plate 31 is formed with an upper stop side thrust groove 33, which matches the block chain.

[0070] Working principle:

[0071] 1. After the block sensing mechanism 15 senses the block 103, the positioning pin 27 extends, and the chain belt traction device 14 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 25 after the positioning pin extends, the front end of the upper stop 105 pushes against the side of the positioning seat 24 and moves forward together until the sensing switch plate 212 fails to detect the signal that the detection baffle 211 represents that the slide 21 moves to the set position, and then the upper stop positioning cylinder 29 is controlled to extend to push against the slide 21 to prevent the slide from being pulled back by the tension spring; then the belt plate cylinder 23 retracts to separate the block chain and the latch chain;

[0072] 2. Then the upper slider mold 41 rises to a predetermined position, so that the slider chain inlet 92 is aligned with the upper stop bevel 106, and then the upper thrust plate 31 pushes the bevel 106 into the slider chain inlet 92;

[0073] 3. Then the chain belt traction mechanism 14 drives the chain belt forward so that the pull head 9 passes through the block chain 101, and continues to move forward until the block sensing mechanism 15 senses the next block 103, controls the auxiliary clamp 51 to clamp the block chain 101, and delays the control of the double positioning mechanism 2 to extend. At this time, the block 103 moves to the rear end of the pull head 9 and is close to the rear end of the pull head 9. The belt passing plate cylinder 23 of the double positioning mechanism extends to move the positioning seat 24 toward the chain belt, and the block positioning cylinder 210 extends to move the positioning seat 24 forward, so that the positioning seat 24 is against the rear end of the block 103 to fix the block 103.

[0074] 4. Then the forward pressing plate 62 presses the latch chain 102 and drives the latch chain 102 to move forward a short distance, so that the latch 104 moves forward to the front of the pull head 9;

[0075] 5. Then the needle stopper cylinder 46 drives the needle stopper 45 to move up to the side of the slider 9. The most ideal position is on the side where the slider 9 and the block 103 are connected to prevent the chain belt from following the pin into the slider and the block when the pin is pushed sideways.

[0076] 6. Then the latch push plate 71 moves the latch chain 102 arranged on the side of the slider closer to the slider, so that the latch 104 moves to the rear of the slider latch opening 91, and the latch 104 is aligned with the latch opening 91 of the slider. At this time, due to the existence of the blocking needle 45, the cloth bag behind the latch is blocked and will not enter the slider and the block.

[0077] 7. While pushing sideways, the forward pressing plate 62 releases the latch chain and resets it, and then the upper clamping plate 83 of the latch sub-chain retracting device 8 clamps the latch sub-chain 102 to move the latch sub-chain 102 backward, and the latch 104 on the latch sub-chain 102 is inserted into the pull head and the block;

[0078] 8. During the process of the bolt chain retreating, the retreating chain belt drives the stopper needle 45 to rotate, and the induction switch 49 senses the deviation of the stopper needle 45, so the stopper needle cylinder 46 is controlled to drive the stopper needle 45 to move down and reset, the bolt push plate 71 retreats and resets, and the positioning seat 24 is also reset;

[0079] 9. Then the front and rear cylinders 43 of the slider drive the upper slider mold 41 to move forward, so that the slider and the block are separated to complete the first distance of chain connection, and then the slider mold 41 descends and resets, and then the traction mechanism drives the chain belt to continue to move forward. Since the positioning pin 27 extends, the chain tooth channel 25 on the positioning seat is smaller than the width of the upper stop 105. Therefore, the upper stop 105 on the block chain 101 drives the positioning seat 24 to move forward to the set position. This position has two positioning functions. The first is to locate the position of the slider 9 that has completed the parallel connection in the previous section, so that the slider is set in front of the long parallel clamp 66, and the long parallel clamp 55 extends and moves forward to complete the long distance of parallel connection; the second is that this position is also the position of the positioning upper stop 105. Therefore, the block chain threading action and the parallel connection of the second section of the long parallel clamp are carried out simultaneously here, which can improve production efficiency.

[0080] The invention has the characteristics of simplifying the working procedure and improving the production speed.

[0081] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
