Description

Technical Field

[0001] The invention belongs to the field of zipper machines and relates to a high-stability oblique-mouth parallel machine. Technical Background

[0002] The traditional zipper molding method first molds the lower stop of the chain, then completes the upper pull head action through the chain threading machine, and then molds the front upper stop, so it requires two injection moldings. Now this bevel upper pull head process can mold the upper stop and lower stop at one time, and then mold the bevel on the chain upper stop with a square, and complete the upper pull head work through the bevel, reducing the process steps and shortening the production line length.

[0003] Chinese invention patent ZL2023115980228, the patent name is a parallel mechanism with an oblique stop band on a chain belt, which discloses that the block position is positioned by a block positioning device, and then the left and right cylinders control the latch chain moving plate to move to the right. Since the initial position of the latch chain moving plate is located at a horizontal line higher than the block chain, the latch after the rightward movement is located above the block, and then the lifting cylinder controls the corresponding block chain clamping wheel to lift, so that the rear traction wheel loses the traction force on the block chain. When the rear traction wheel rotates, only the latch chain retreats, so that the latch retreats to the rear and upper part of the block, and then the upper and lower cylinders control the latch chain moving plate to move downward, so that the latch is located behind the block and the pull head socket; then the front traction device controls the chain belt to move forward to insert the latch into the pull head and the block socket, thereby completing the parallel connection.

[0004] Although the device can complete the automatic chaining process for the chain belt that has been injection molded with upper and lower stops and has been threaded with a pull head, the device has the following two problems: 1. Since the front and rear driving forces of the pin chain are all from the traction wheel, and the traction wheel is also the driving force for the chain belt traction, after the front traction wheel inserts the pin into the pull head and the block, the front traction wheel drives the block chain and the pin chain to move simultaneously to complete the parallel connection. At this time, the pin is often not inserted to the bottom, affecting the stability of production;

[0005] Second: because the clamping wheel on the block chain is in the lifted state during the process of the pin being inserted into the pull head and the block, the chain belt on the block chain will become loose, affecting the stability of production. Summary of the invention

[0006] In view of the above problems, the present invention provides a high-stability oblique-mouth parallel machine, which has the advantage of being able to improve the stability of the pin being inserted to the bottom, thereby improving the overall production stability.

[0007] The object of the present invention is achieved in that:

[0008] A high-stability oblique parallel machine comprises a chain belt traction device and a chain belt platform, the chain belt platform is divided into a block chain channel and a latch chain channel, the block chain channel is provided with a block fixing device, the front of the latch chain channel is provided with a latch chain lowering plate and a lowering cylinder driving the latch chain lowering plate to move up and down, the latch chain lowering plate is formed with a latch chain groove, the front of the latch chain lowering plate is provided with a latch chain forward clamp, a first clamping cylinder driving the forward clamp to open and close, and a forward drive driving the latch chain forward clamp to move forward, the rear of the latch chain lowering plate is provided with a latch chain retracting clamp, a second clamping cylinder driving the retracting clamp to open and close, and a first-stage latch cylinder and a second-stage parallel cylinder driving the latch chain retracting clamp to move backward;

[0009] A long parallel device is also arranged in front of the latch branch chain downward moving plate.

[0010] Through the above settings, the forward clamp of the latch chain drives the latch chain forward, so that the latch moves to the upper front of the pull head socket, the lower plate of the latch chain moves downward to move the latch to the front of the latch socket, and then the backward clamp of the latch chain inserts the latch into the pull head and the block under the drive of a first-stage latch cylinder. At this time, no matter whether the latch is inserted to the bottom or not, since the backward clamp of the latch chain is clamped separately on the latch chain, when the two-stage parallel cylinder drives the latch chain to retreat to complete the parallel connection, it can ensure that the latch is inserted to the bottom and then completes the parallel connection, thereby improving the stability of the latch being inserted to the bottom and improving the stability of the overall production.

[0011] The present invention is further configured as follows: the latch chain retraction clamp is slidably arranged on a slide rail, a two-stage parallel cylinder is arranged behind the latch chain retraction clamp and fixed on a frame, the protruding ends of the two-stage parallel cylinders extend forward and are connected to a slide seat, the slide seat is also slidably arranged on the slide rail, the one-stage latch cylinder is fixed on the slide seat, and the protruding end of the one-stage latch cylinder extends forward and is fixedly connected to the latch chain retraction clamp.

[0012] The present invention is further configured as follows: a block chain splitting auxiliary clamp and an auxiliary clamp cylinder for driving the auxiliary clamp to open and close are provided at the rear of the block chain splitting channel; a tension spring is connected to the block chain splitting auxiliary clamp, and the tension spring always gives the block chain splitting auxiliary clamp a force to move backward; an auxiliary clamp reset cylinder is also provided at the rear of the block chain splitting auxiliary clamp, and the protruding end of the auxiliary clamp reset cylinder extends forward and presses against the rear end of the block chain splitting auxiliary clamp.

[0013] By setting the block chain auxiliary clamp and the tension spring, when the pin chain retreat clamp drives the pin chain to retreat, the tension spring drives the block chain auxiliary clamp to clamp the block chain backward, so that the chain belt in front can be in a straightened state, preventing the loose block chain from interfering with the pin chain or other mechanisms, thereby improving the overall production stability.

[0014] The present invention is further configured as follows: the long parallel device includes a long parallel clamp arranged in front of the latch chain lower moving plate, left and right cylinders driving the long parallel clamp to move left and right, and a long parallel drive driving the long parallel clamp to move forward and backward, and a parallel groove is formed on the long parallel clamp.

[0015] Through the above settings, after the two-section parallel cylinder drives the pin chain retracting clamp to complete the parallel connection for a short distance, the long parallel device is used to complete the parallel connection of the remaining unconnected parts. The parallel connection is divided into two sections in order to shorten the working station length of the pin entering the pull head part.

[0016] The present invention is further configured as follows: the long parallel clamp is fixed on the protruding ends of the left and right cylinders, the left and right cylinders are fixed on the slide, the latch chain forward clamp and the first clamping cylinder are also fixed on the slide, the slide is slidably arranged on the linear module, and the long parallel drive of the long parallel clamp and the forward drive of the latch chain forward clamp are both linear modules.

[0017] Through the above arrangement, the assembly space can be saved and the structure can be made more compact.

[0018] The present invention is further configured as follows: the latch chain slot includes a chain tooth slot and a chain belt slot. Through the above configuration, the latch chain slot and the chain belt can be more closely matched, so that the slot drives the chain belt to move and position more accurately.

[0019] The present invention is further configured as follows: a flattening auxiliary platform is also provided in front of the chain belt platform, and the flattening auxiliary platform is provided with two auxiliary channels corresponding to the two branch chains, and the two auxiliary channels are provided with elastic steel sheets fixed on the frame, and the front ends of the elastic steel sheets are tilted downward, and the front ends of the two elastic steel sheets are bent and rest against the corresponding auxiliary channels.

[0020] Through the above settings, the chain belt can run more smoothly.

[0021] The present invention is further configured as follows: a chain platform is provided in front of the chain belt platform, a pull head fixing groove and a block fixing groove are provided adjacent to the chain platform in sequence, the rear of the block fixing groove is open, and the block fixing device presses against the rear of the block from the open position to fix the block.

[0022] Through the above settings, after the block chain is threaded with the pull head, the pull head and the block are positioned together. After the pin is inserted into the pull head and the block, the block fixing device releases the block, allowing the block to move backward from the block fixing groove to create a distance from the pull head, thereby completing the parallel connection.

[0023] The present invention is further configured as follows: the block fixing device includes a fixed cylinder, a movable seat, a rocker rod and a fixed rod, the protruding end of the fixed cylinder protrudes forward and is fixedly connected to the movable seat, a transverse groove for the rocker rod to swing is formed in the movable seat, the rocker rod is arranged in the transverse groove by rotating through a pin shaft, a swing cylinder is provided on the movable seat, the protruding end of the swing cylinder protrudes downward and abuts against the rear end of the rocker rod, the front end of the rocker rod is fixedly connected to the fixed rod, and a fixing groove matching the block is formed at the lower end of the fixed rod.

[0024] Through the above arrangement, when the block moves to the block fixing groove behind the slider, the extended end of the swing cylinder retracts, the fixing rod moves downward, and then the extended end of the fixing cylinder extends forward, driving the fixing rod to move forward, so that the fixing groove on the fixing rod just hits the block, thus fixing the block. Then, after the latch is inserted into the slider and the block, the extended end of the swing cylinder extends, the fixing rod moves upward, and the extended end of the fixing cylinder retracts, driving the fixing rod to retract and reset, thus losing the fixation of the block, and the block can retreat from the opening of the block fixing groove, so that the block and the slider are separated by a distance to achieve parallel connection.

[0025] The present invention is further configured as follows: a latch detection mechanism is also provided on the latch chain channel, the latch detection mechanism includes a slide bar seat, a slide bar is slidably arranged in the slide bar seat, a roller is rotatably arranged at the lower end of the slide bar, the roller is arranged on the latch chain channel and on the travel path of the latch; a detection switch for detecting the upper end of the slide bar is fixed on the slide bar seat; a limit pin is also provided in the slide bar seat, and a limit groove is also formed on the slide bar seat.

[0026] By setting up the latch detection mechanism, it is possible to determine whether there is a latch on the latch chain. If there is no latch, the equipment will be controlled to stop moving, thereby improving production stability.

[0027] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects: the forward clamp of the latch chain drives the latch chain forward, so that the latch moves to the upper front of the pull head socket, the lower moving plate of the latch chain moves downward to move the latch to the front of the latch socket, and then the backward clamp of the latch chain inserts the latch into the pull head and the block under the drive of a first-stage latch cylinder. At this time, no matter whether the latch is inserted to the bottom or not, since the backward clamp of the latch chain is clamped separately on the latch chain, when the two-stage parallel cylinder drives the latch chain to retreat to complete the parallel connection, it can ensure that the latch is inserted to the bottom and then completes the parallel connection, thereby improving the stability of the latch being inserted to the bottom and improving the stability of the overall production.

[0046] 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.

[0047] A high-stability oblique parallel machine, comprising a chain belt traction device 100 and a chain belt platform 2, the chain belt platform 2 is divided into a block chain channel 21 and a latch chain channel 22, the block chain channel 21 is provided with a block fixing device 9, the front of the latch chain channel 22 is provided with a latch chain down plate 3 and a down cylinder 31 for driving the latch chain down plate 3 to move up and down, the latch chain down plate 3 is formed with a latch chain groove, the latch chain groove includes a chain tooth The slide groove 32 and the chain belt slide groove 33, the front of the latch chain downward moving plate 3 is provided with a latch chain forward clamp 4, a first clamping cylinder 41 that drives the forward clamp to open and close, and a forward drive that drives the latch chain forward clamp 4 to move forward, and the rear of the latch chain downward moving plate 3 is provided with a latch chain retracting clamp 5, a second clamping cylinder 51 that drives the retracting clamp to open and close, and a first latch cylinder 52 and a second parallel cylinder 53 that drive the latch chain retracting clamp 5 to move backward;

[0048] A long parallel device 6 is also provided in front of the latch chain downward moving plate 3 .

[0049] Through the above arrangement, the latch chain forward clamp 4 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 3 moves downward to move the latch 104 to the front of the slider socket 110, and then the latch chain retracting clamp 5 inserts the latch 104 into the slider 109 and the block 103 under the drive of a first-stage latch cylinder 52. At this time, regardless of whether the latch 104 is inserted to the bottom or not, since the latch chain retracting clamp 5 is clamped separately on the latch chain 102, when the second-stage parallel cylinder 53 drives the latch chain 102 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 104 being inserted to the bottom and improving the stability of the overall production.

[0050] The latch chain retracting clamp 5 is slidably set on the slide rail 54, the two-stage parallel cylinder 53 is set behind the latch chain retracting clamp 5 and fixed on the frame 0, the protruding end of the two-stage parallel cylinder 53 extends forward and is connected with a slide seat 55, and the slide seat 55 is also slidably set on the slide rail 54, the one-stage latch cylinder 52 is fixed on the slide seat 55, and the protruding end of the one-stage latch cylinder 52 extends forward and is fixedly connected to the latch chain retracting clamp 5.

[0051] A block chain auxiliary clamp 7 and an auxiliary clamp cylinder 71 for driving the auxiliary clamp to open and close are provided at the rear of the block chain channel 21. A tension spring (not shown) is connected to the block chain auxiliary clamp 7. The tension spring always gives the block chain auxiliary clamp 7 a force to move backward. An auxiliary clamp reset cylinder 73 is also provided at the rear of the block chain auxiliary clamp 7. The extended end of the auxiliary clamp reset cylinder 73 extends forward and abuts against the rear end of the block chain auxiliary clamp 7. Through the arrangement of the block chain auxiliary clamp 7 and the tension spring 71, when the latch chain retreat clamp 5 drives the latch chain 102 to retreat, the tension spring 71 drives the block chain 101 auxiliary clamp to retreat with the block chain 101, 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.

[0052] The long parallel device 6 includes a long parallel clamp 61 arranged in front of the bolt chain lowering plate 3, a left and right cylinder 62 driving the long parallel clamp 61 to move left and right, and a long parallel drive driving the long parallel clamp to move forward and backward. A parallel groove 63 is formed on the long parallel clamp 61, and the width of the parallel groove is smaller than the width of the pull head. Through the above arrangement, after the two-stage parallel cylinder 53 drives the bolt chain 102 to retreat the clamp to complete the parallel connection for a short distance, the long parallel device completes the parallel connection of the remaining unconnected parts. The purpose of dividing the parallel connection into two sections is to shorten the station length of the bolt into the pull head part.

[0053] The long parallel clamp 61 is fixed on the extended ends of the left and right cylinders 62, the left and right cylinders 62 are fixed on the slide 64, the latch chain forward clamp 4 and the first clamping cylinder 41 are also fixed on the slide 64, the slide 64 is slidably arranged on the linear module 65, and the long parallel drive of the long parallel clamp 6 and the forward drive of the latch chain forward clamp are both linear modules 65. Through the above arrangement, the assembly space can be saved and the structure can be made more compact.

[0054] A flattening auxiliary platform 11 is also provided in front of the chain belt platform 2. The flattening auxiliary platform 11 is provided with two auxiliary channels 12 corresponding to the two branch chains. The two auxiliary channels 12 are provided with elastic steel sheets 13 fixed on the frame. The front ends of the elastic steel sheets 13 are tilted downward. The front ends of the two elastic steel sheets 13 are bent and abut against the corresponding auxiliary channels 12. Through the above arrangement, the chain belt can run more smoothly.

[0055] A chain paralleling platform 23 is provided in front of the chain belt platform 2, and a slider fixing slot 24 and a block fixing slot 25 are arranged adjacent to the slider fixing slot 24 and the block fixing slot 25 in sequence. The rear of the block fixing slot 25 is open, and the block fixing device abuts against the rear of the block 103 from the open position to fix the block 103. Through the above arrangement, after the slider 109 is inserted into the block chain 101, the slider 109 and the block 103 are positioned together, and after the latch 104 is inserted into the slider 109 and the block 103, the block fixing device releases the block 103, so that the block 103 can move backward from the slider fixing slot 25 to create a distance from the slider 109, thereby completing the parallel connection.

[0056] The block fixing device 9 comprises a fixed cylinder 91, a moving seat 92, a swing rod 93 and a fixed rod 94. The extended end of the fixed cylinder 91 extends forward and is fixedly connected to the moving seat 92. A transverse groove 95 is formed in the moving seat 92 for the swing rod 93 to swing. The swing rod 93 is rotatably arranged in the transverse groove 95 through a pin 96. A swing cylinder 97 is provided on the moving seat 92. The extended end of the swing cylinder 97 extends downward and abuts against the rear end of the swing rod 93. The front end of the swing rod 93 is fixedly connected to the fixed rod 94. The lower end of the fixed rod 94 is formed with a fixed groove 98 matching the block. Through the above arrangement, when the block 103 moves to the block fixing groove 24 behind the pull head 109, the extended end of the swing cylinder 97 retracts, the fixed rod 94 moves downward, and then the extended end of the fixed cylinder 91 extends forward, driving the fixed rod 94 to move forward, so that the fixed groove 98 on the fixed rod 94 just presses against the block 103, thereby fixing the block 103. Then, after the latch 104 is inserted into the slider 109 and the block 103, the protruding end of the swing cylinder 97 extends out, the fixing rod 94 moves upward, and the protruding end of the fixing cylinder 91 retracts, driving the fixing rod 94 to retract and return to its original position, losing the fixation on the block 103. The block 103 can retreat from the opening of the block fixing groove 98, so that the block and the slider are separated by a distance to achieve parallel connection.

[0057] The latch chain channel 22 is also provided with a latch detection mechanism 8, which includes a slide bar seat 81, in which a slide bar 82 is slidably arranged, and a roller 83 is rotatably arranged at the lower end of the slide bar 82, and the roller 83 is arranged on the latch chain channel 22 and on the path of the latch; a detection switch 84 for detecting the upper end of the slide bar is fixed on the slide bar seat 81; a limit pin 85 is also arranged in the slide bar seat 81, and a limit groove is also formed on the slide bar seat 81. Through the setting of the latch detection mechanism, it is possible to determine whether there is a latch on the latch chain, and if there is no latch, the device will be controlled to stop moving, thereby improving the stability of production.

[0058] Working principle:

[0059] First, the pull head 109 fixed on the pull head fixing groove 24 is inserted into the block chain 101 with bevel teeth, and then the chain belt traction device 1 drives the chain belt 10 to move forward, so that the block 103 moves to the block fixing groove 25 behind the pull head 109, and then the protruding end of the swing cylinder 97 retracts, the fixing rod 94 moves downward, and the protruding end of the fixing cylinder 91 extends forward, driving the fixing rod 94 to move forward, so that the fixing groove 98 on the fixing rod 94 just hits the block 103, thereby fixing the block 103.

[0060] Then the latch chain forward moving clamp 4 clamps 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 and upper part of the pull head socket 110, and then the latch chain lowering plate 3 drives the latch 104 to move downward, so that the latch 104 is located in front of the pull head socket 110, and then the first-stage latch cylinder 52 drives the latch chain backward clamp 5 to clamp the latch chain 102 and retreat a short distance, so that the latch 104 is inserted into the pull head 109 and the block 103. Then the fixing rod releases the fixation of the block 103, and the second-stage parallel cylinder 53 drives the latch chain backward clamp 5 to clamp the latch chain 102 and retreat a distance for the second time. Since the pull head 109 is still fixed by the pull head fixing groove 24 on the parallel platform 23 at this time, the latch 104 and the block 103 are separated from the pull head 109 by one end, completing the parallel connection of a short distance.

[0061] When the latch chain retracting clamp 5 clamps the latch chain 102, the block chain auxiliary clamp 7 clamps the block chain 101. When the latch chain retracting clamp 5 drives the latch chain 102 to retreat, the protruding end of the auxiliary clamp reset cylinder 73 retracts, and the tension spring 72 drives the block chain auxiliary clamp 7 to clamp the block chain 101 and retreat, so that the chain belt in front can be in a straightened state.

[0062] Then the pin chain retracting clamp 5 and the block chain auxiliary clamp 7 are both opened, the parallel platform 23 (pull head mold) moves down and loses the fixation on the pull head 109, and the chain belt moves forward under the action of the traction mechanism. When the pull head moves in front of the long parallel clamp 61, the long parallel clamp 61 extends toward the chain belt, and the parallel groove 63 on the long parallel clamp 6 is against the rear of the pull head 109. Then the long parallel clamp 6 moves forward to drive the pull head 109 to complete the parallel connection of the remaining long distance unconnected part.

[0063] The present invention has the characteristics of being able to improve the stability of the latch being inserted to the bottom, thereby improving the overall production stability.

[0064] 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.
