Description

Technical Field

[0001] This application relates to the field of zipper production equipment technology, specifically a zipper punching machine. Background Technology

[0002] In the zipper production process, teeth need to be formed on the zipper belt. The teeth are arranged continuously during the forming process. The entire zipper belt needs to be divided into multiple zipper units. The teeth between each zipper unit are punched and removed by a tooth punching machine to break and remove the teeth on the zipper belt between adjacent zipper units. A zipper tooth punching machine is required.

[0003] Existing zipper punching machines typically involve pressing and positioning the zipper at one end, while the other end remains free to move. During the punching process, the unfixed portion of the zipper may lift up, affecting the punching quality and the neatness of the teeth at both ends of the zipper after punching. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a zipper toothing machine that can stably press and fix the zipper belt around the toothed area during toothing, preventing the belt from lifting up near the toothed area, improving the quality of the finished product, and ensuring high uniformity of the teeth at both ends of the zipper belt. This solves the problem that existing zipper toothing machines typically only press and fix one end of the zipper belt, leaving the other end free to move. This can cause the unfixed part of the zipper belt to lift up during toothing, affecting the quality of toothing and the uniformity of the teeth at both ends of the zipper belt after toothing.

[0005] To achieve the aforementioned goal of stably pressing and fixing the perimeter of the zipper teeth during punching, preventing warping near the punching area, improving the finished product quality of the zipper teeth, and ensuring high uniformity of the teeth at both ends of the zipper, this application provides the following technical solution: a zipper punching machine, including a frame. A first hydraulic rod is mounted on the top of the frame via a support frame. One end of the inner hydraulic rod of the first hydraulic rod is mounted with a punching cutter via an mounting assembly. A second hydraulic rod is mounted on the top of the frame via a support frame. One end of the inner hydraulic rod of the second hydraulic rod is connected to an adjusting assembly via a pressure adapting assembly. The adjusting assembly is connected to two connecting plates. Two first pressure plates are provided at one end of the two connecting plates. The two first pressure plates are located below both ends of the punching cutter. Two second pressure plates are provided between the two first pressure plates. The two second pressure plates are located below both sides of the punching cutter. The first pressure plates and the second pressure plates are connected by a connecting assembly.

[0006] Through the above scheme, the second hydraulic rod operates, causing the pressure adaptation component to push the connecting plate downward, which in turn moves the two first pressure plates and two second pressure plates downward to press against the periphery of the chain belt punch teeth. This achieves stable pressing and fixing of the periphery of the chain belt punch teeth during punching, preventing the area near the chain belt punch teeth from lifting up, improving the finished product quality of the chain belt punch teeth, and ensuring that the teeth at both ends of the chain belt have a high degree of uniformity.

[0007] Furthermore, both the first pressure plate and the second pressure plate are provided with anti-slip pads at their bottoms, and the anti-slip pads are made of anti-slip rubber material.

[0008] By using the above solution, and by setting anti-slip pads made of anti-slip rubber material at the bottom of the first pressure plate and the second pressure plate, the friction between the first pressure plate and the second pressure plate and the surface of the chain can be effectively increased, preventing the chain from slipping due to the pulling at the punching teeth during the punching process, and improving the stability of the first pressure plate and the second pressure plate in holding the chain.

[0009] Furthermore, the installation assembly includes a plug rod and a sleeve. One end of the plug rod is disposed at one end of the hydraulic inner rod of the first hydraulic rod, and the sleeve is disposed at the top of the punch cutter. The plug rod is inserted into the inner wall of the sleeve, and the plug rod and the sleeve are fixedly connected by fastening bolts.

[0010] With the above solution, the installation component, through the plug-in structure of the plug rod and the sleeve, combined with the lateral fixation of the fastening bolts, can quickly assemble and disassemble the punch cutter and the first hydraulic rod, and can easily and quickly replace punch cutters of different specifications according to punch requirements.

[0011] Furthermore, the pressure adaptation component includes a telescopic rod and a spring. One end of the telescopic rod's outer telescopic tube is located at one end of the second hydraulic rod's inner hydraulic rod, and one end of the telescopic rod's inner telescopic rod is located at the top of the adjustment component. A spring is installed inside the telescopic rod.

[0012] Through the above scheme, after the first and second pressure plates contact the chain belt, the second hydraulic rod holds...

[0013] Continuing to press down can retract the telescopic rod, compressing the spring. Through the spring and the telescopic rod, appropriate pressure can be applied to the chain, maintaining a stable pressure on the chain.

[0014] Furthermore, the adjustment assembly includes a connecting frame, and a threaded rod is rotatably disposed inside the connecting frame. The outer surfaces of the two sides of the middle part of the threaded rod are threadedly connected to the inner wall of one side of the middle part of the two connecting plates.

[0015] The above scheme allows the connecting plate to move by rotating the threaded rod, thereby adjusting the position of the two connecting plates and consequently adjusting the position of the two first pressure plates. This allows the position of the two first pressure plates to adapt to the requirements of punches of different lengths.

[0016] Furthermore, the inner wall of one end of the connecting plate is slidably disposed on the outer surface of one side of the middle part of the limiting rod, and the two ends of the limiting rod are disposed at the two ends of the inner wall of the middle part of the connecting frame.

[0017] With the above solution, the inner wall of one end of the connecting plate slides on the outer surface of the middle side of the limiting rod, which can be used in conjunction with the threaded rod to fix the angle when the connecting plate moves, thereby improving the stability when the connecting plate drives the first pressure plate to move.

[0018] Furthermore, the thread directions on the outer surfaces of the two sides of the middle part of the threaded rod are opposite, and the thread directions on the outer surfaces of the two sides of the middle part of the threaded rod are adapted to the thread direction on one side of the inner wall of the two connecting plates.

[0019] With the above solution, by setting the thread direction on the outer surfaces of both sides of the middle of the threaded rod, the two connecting plates can be moved in different directions by rotating the threaded rod. The two connecting plates can be centered and adjusted so that the distance and position between the two connecting plates can be precisely adapted to the requirements of punches of different lengths.

[0020] Furthermore, the connecting assembly includes a connecting frame and a plug-in bracket. The connecting frame is disposed at the end of the upper surface of the first pressure plate, and the plug-in bracket is disposed at the end of the upper surface of the second pressure plate. One end of the outer surface of the plug-in bracket is inserted into the inner wall of the middle part of the connecting frame, and the plug-in bracket and the connecting frame are fixedly connected by fastening bolts.

[0021] The above solution allows for the quick assembly and disassembly of the second pressure plate between the two first pressure plates using a plug-in bracket and connecting frame. This enables the easy and rapid replacement of the second pressure plate with the appropriate length according to different punch length requirements.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This zipper punching machine operates via a second hydraulic rod, causing the pressure adaptation component to push the connecting plate downwards. This, in turn, moves two first pressure plates and two second pressure plates downwards to press against the perimeter of the zipper teeth. This achieves stable pressing and fixing of the perimeter of the zipper teeth during punching, preventing warping near the teeth and improving the quality of the finished product. This results in a higher degree of uniformity in the teeth at both ends of the zipper. Attached Figure Description

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please refer to Figures 1, 2, and 3. The zipper punching machine in this embodiment includes a frame 1. A first hydraulic rod 2 is mounted on the top of the frame 1 via a support frame. One end of the inner hydraulic rod of the first hydraulic rod 2 is mounted with a punching cutter 4 via a mounting assembly 3. A second hydraulic rod 5 is mounted on the top of the frame 1 via a support frame. One end of the inner hydraulic rod of the second hydraulic rod 5 is connected to an adjusting assembly 7 via a pressure adapting assembly 6. The adjusting assembly 7 is connected to two connecting plates 8. Two first pressure plates 10 are provided at one end of the two connecting plates 8. The two first pressure plates 10 are located below both ends of the punching cutter 4. Two second pressure plates 11 are provided between the two first pressure plates 10. The two second pressure plates 11 are located below both sides of the punching cutter 4. The first pressure plates 10 and the second pressure plates 11 are connected by a connecting assembly 9.

[0034] Please refer to Figures 1 and 2. Figure 5Both the first pressure plate 10 and the second pressure plate 11 are provided with anti-slip pads 12 at their bottoms. The anti-slip pads 12 are made of anti-slip rubber. By providing anti-slip rubber pads 12 at the bottoms of the first pressure plate 10 and the second pressure plate 11, the friction between the first pressure plate 10 and the second pressure plate 11 and the surface of the chain can be effectively increased, preventing the chain from slipping due to the pulling at the punching teeth during the punching process, and improving the stability of the first pressure plate 10 and the second pressure plate 11 in holding the chain.

[0035] Please refer to Figures 2, 3, and 6. The mounting assembly 3 includes a plug rod 301 and a sleeve 302. One end of the plug rod 301 is located at one end of the hydraulic inner rod of the first hydraulic rod 2. The sleeve 302 is located at the top of the punch cutter 4. The plug rod 301 is inserted into the inner wall of the sleeve 302. The plug rod 301 and the sleeve 302 are fixedly connected by fastening bolts. Through the plug-in structure of the plug rod 301 and the sleeve 302, combined with the lateral fixation of the fastening bolts, the mounting assembly 3 can quickly assemble and disassemble the punch cutter 4 and the first hydraulic rod 2, and can easily and quickly replace punch cutters 4 of different specifications according to punching requirements.

[0036] Please refer to Figures 1 and 2. Figure 4 The pressure adaptation component 6 includes a telescopic rod 601 and a spring 602. One end of the telescopic rod 601's outer telescopic tube is located at one end of the hydraulic inner rod of the second hydraulic rod 5, and the other end of the telescopic rod 601's inner telescopic rod is located at the top of the adjustment component 7. The spring 602 is installed inside the telescopic rod 601. After the first pressure plate 10 and the second pressure plate 11 come into contact with the chain belt, the continuous downward pressure of the second hydraulic rod 5 can cause the telescopic rod 601 to retract, compressing the spring 602. Through the cooperation of the spring 602 and the telescopic rod 601, appropriate pressure can be applied to the chain belt, maintaining a stable pressure on the chain belt.

[0037] Please refer to Figure 1 and Figure 2 The adjusting component 7 includes a connecting frame 701, inside which a threaded rod 702 is rotatably mounted. The outer surfaces of the two sides of the middle part of the threaded rod 702 are threaded to the inner wall of one side of the middle part of the two connecting plates 8. By rotating the threaded rod 702, the connecting plates 8 can be moved, and the positions of the two connecting plates 8 can be adjusted, thereby adjusting the positions of the two first pressure plates 10 so that the positions of the two first pressure plates 10 can adapt to the requirements of punch teeth of different lengths.

[0038] Please refer to Figure 1 and Figure 2One end of the inner wall of the connecting plate 8 is slidably disposed on the outer surface of the middle side of the limiting rod 703. The two ends of the limiting rod 703 are disposed on the two ends of the inner wall of the middle part of the connecting frame 701. The inner wall of one end of the connecting plate 8 slides on the outer surface of the middle side of the limiting rod 703, which can cooperate with the threaded rod 702 to fix the angle when the connecting plate 8 moves, thereby improving the stability when the connecting plate 8 drives the first pressure plate 10 to move.

[0039] Please refer to Figure 1 and Figure 2 The threads on the outer surfaces of the two sides of the middle section of the threaded rod 702 are set in opposite directions. The threads on the outer surfaces of the two sides of the middle section of the threaded rod 702 are adapted to the threads on the inner wall of one side of the two connecting plates 8. By setting the threads on the outer surfaces of the two sides of the middle section of the threaded rod 702, the two connecting plates 8 can be moved in different directions by rotating the threaded rod 702. The two connecting plates 8 can be adjusted to be centered, so that the distance and position between the two connecting plates 8 can be precisely adapted to the requirements of punches of different lengths.

[0040] Please refer to Figures 2, 3, and 5. The connecting assembly 9 includes a connecting frame 901 and a plug-in bracket 902. The connecting frame 901 is located at the end of the upper surface of the first pressure plate 10, and the plug-in bracket 902 is located at the end of the upper surface of the second pressure plate 11. One end of the outer surface of the plug-in bracket 902 is inserted into the inner wall of the middle part of the connecting frame 901. The plug-in bracket 902 and the connecting frame 901 are fixedly connected by fastening bolts. By using the plug-in bracket 902 in conjunction with the connecting frame 901, the second pressure plate 11 between the two first pressure plates 10 can be quickly disassembled and assembled. It is convenient to quickly replace the second pressure plate 11 of the appropriate length according to different punch length requirements.

[0041] In this embodiment, the zipper punching machine operates via the second hydraulic rod 5, causing the pressure adaptation component 6 and the adjustment component 7 to push the connecting plate 8 downwards. This causes the two first pressure plates 10 and the two second pressure plates 11 to move downwards and press against the periphery of the zipper punching area. This achieves stable pressing and fixing of the periphery of the zipper punching area during punching, preventing the area near the zipper punching area from lifting up. This improves the finished product quality of the zipper punching and ensures that the teeth at both ends of the zipper have a high degree of uniformity.

[0042] The working principle of the above embodiment is as follows: Place the chain belt that needs to be punched on the punching frame at the top of the frame 1. According to the required punching length, remove the fastening bolts between the sleeve 302 and the insert rod 301, remove the sleeve 302 from the insert rod 301, replace the punching cutter 4, and put the sleeve 302 at the top of the punching cutter 4 that matches the punching length onto the insert rod 301. Use fastening bolts to fix the insert rod 301 and the sleeve 302. Remove the fastening bolts between the connecting frame 901 and the insert bracket 902, so that the outer surface of one end of the insert bracket 902 slides out from the middle inner wall of the connecting frame 901. Remove the two second pressure plates 11 from between the two first pressure plates 10. Rotate the threaded rod 702 to drive the two connecting plates 8 to move, so that the two connecting plates 8 move in different directions, so that the two connecting plates 8 drive the two first pressure plates 10 to move. Adjust the two first pressure plates 10. The distance between the two first pressure plates 10 is adjusted to match the length requirements of the punch. A second pressure plate 11, which is suitable for the distance between the two first pressure plates 10, is installed between the two first pressure plates 10. The outer surface of one end of the plug-in bracket 902 at both ends of the top of the second pressure plate 11 is inserted into the inner wall of the corresponding two connecting frames 901. Fastening bolts are used to fix the plug-in bracket 902 to the connecting frame 901, completing the installation of the second pressure plate 11. When punching, the second hydraulic rod 5 works, pushing the adjusting component 7 downward through the pressure adaptation component 6. The adjusting component 7 pushes the two first pressure plates 10 and the two second pressure plates 11 downward through the connecting plate 8. After the first pressure plates 10 and the second pressure plates 11 contact the chain belt, the continuous work of the second hydraulic rod 5 causes the telescopic rod 601 to retract, compressing the spring 602, so that the two first pressure plates 10... With the two second pressure plates 11 stably pressing and holding the chain belt around the punch teeth, the first hydraulic rod 2 works, driving the punch knife 4 downward through the mounting component 3, so that the punch knife 4 punches the chain belt held by the first pressure plate 10 and the second pressure plate 11.
