Description

Technical Field

[0001] This invention belongs to the field of tape processing technology, specifically a tape processing and die-cutting device. Background Technology

[0002] Adhesive tape, as a commonly used adhesive material, is widely used in many industries such as electronics, printing and packaging, automobile manufacturing, and medical consumables. Die-cutting is an essential step in the tape processing. Die-cutting involves precisely cutting the tape under pressure using a die-cutting blade to form a pre-set shape and size, thus meeting the needs of different applications.

[0003] Patent application CN119188908A discloses a tape processing and die-cutting device. The key technical features are: a platform with a die-cutting mechanism mounted on its top surface. The die-cutting mechanism includes a connecting frame fixed to the top surface of the platform, a processing section slidably connected to the top surface of the connecting frame, a processing plate on the top of the platform, a buffer mechanism between the processing plate and the platform, the processing plate being located within the connecting frame and below the processing section, an input mechanism on one side of the platform, an output mechanism on the side of the platform away from the input mechanism, and a guide mechanism on the side of the platform near the output mechanism. The guide mechanism is rotatably connected to the connecting frame. The tape to be processed enters the connecting frame through the input mechanism and is placed on the top surface of the processing plate. The processing section processes the tape, the buffer mechanism provides cushioning force to the processing plate, and the processed tape is collected in the output mechanism via the guide mechanism.

[0004] However, the above-mentioned technologies often have the following drawbacks: when the existing devices are in use, they lack effective guidance for the tape entering the processing plate, which makes it impossible for the tape to be processed to be precisely aligned with the processing part, making the processing process prone to errors, and thus affecting the processing effect of the device. Therefore, the present invention provides a tape processing die-cutting device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: the tape processing and die-cutting device of the present invention includes a worktable, support blocks are fixedly connected to the four corners of the bottom of the worktable, and handles are fixedly connected to the front and rear surfaces of the worktable.

[0007] A processing plate is installed at the center of the top of the workbench via a buffer assembly. An L-shaped support frame is fixedly connected to the rear of the center of the top of the workbench. A die-cutting assembly is installed on the L-shaped support frame. Guide assemblies are installed on both the left and right sides of the top of the workbench.

[0008] The guide assembly includes two support plates, which are fixedly connected to the front and rear of the top of the workbench, respectively. A guide roller is provided between the two support plates through an adjustment assembly. A connecting plate is fixedly connected to the opposite side of each of the two support plates. A guide roller is rotatably installed between the two connecting plates.

[0009] Preferably, a bidirectional screw is rotatably installed between the lower interior of the two support plates. The front and rear of the outer surface of the bidirectional screw are threaded with internal threaded sleeves. A limit plate is fixedly connected to the outer surface of the internal threaded sleeve. The guide roller passes through the limit plate. A motor is fixedly connected to the front surface of the front support plate. The output end of the motor is fixedly connected to the front end of the bidirectional screw.

[0010] Preferably, a limiting groove is provided at the top of the workbench corresponding to the bidirectional screw, and limiting blocks are slidably connected to the front and rear of the limiting groove, and the limiting blocks are fixedly connected to the internal threaded sleeve.

[0011] Preferably, the adjusting assembly includes two slide grooves, which are respectively opened on opposite sides of the two support plates. An adjusting plate is slidably connected inside the slide groove. The guide roller is rotatably installed between the two adjusting plates. A moving assembly is provided between the two adjusting plates and the two support plates.

[0012] Preferably, the slide groove has through guide grooves on both the left and right sides, and guide blocks are slidably connected inside the guide grooves. The guide blocks are fixedly connected to the adjusting plate.

[0013] Preferably, the moving component includes two inner grooves, which are respectively opened inside and above the two support plates. A threaded rod is rotatably installed between the inner groove and the slide groove. A driving component is provided between the two threaded rods. An internal threaded sleeve is threadedly connected to the lower outer surface of the threaded rod. The internal threaded sleeve is fixedly connected to the adjusting plate.

[0014] Preferably, the drive assembly includes a rotating rod, which is rotatably mounted inside the inner groove. A second motor is fixedly mounted inside the inner groove at the front. The output end of the second motor is fixedly connected to the rotating rod at the front. A second helical gear is fixedly connected to the outer surface of the rotating rod. A first helical gear is fixedly connected to the top of the threaded rod. The first helical gear and the second helical gear are meshed together. The opposite ends of the two rotating rods extend to the outside of the support plate and are fixedly connected to a connecting rod.

[0015] Preferably, the die-cutting assembly includes a hydraulic cylinder, which is fixedly installed on the top of the L-shaped support frame. The output end of the hydraulic cylinder passes through the upper part of the L-shaped support frame and is fixedly installed with a die-cutting blade. Guide rods are fixedly connected to the four corners of the top of the die-cutting blade, and the top ends of the guide rods pass through the top of the L-shaped support frame.

[0016] Preferably, the buffer assembly includes four buffer rods, which are fixedly connected to the four corners of the bottom of the processing plate. Each buffer rod has a support rod at its bottom end and is slidably connected to the support rod. Springs are fixedly connected between the four corners of the top of the processing plate and the top of the worktable, and the springs are sleeved on the outside of the buffer rods and the support rods.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The tape processing and die-cutting device of the present invention can guide and limit the position of the tape during the tape conveying process by setting a guide component, so that the tape always stays on the preset conveying path, ensuring that the tape conveyed to the processing plate can be accurately aligned with the die-cutting component, reducing the positional deviation of the die-cutting process, and effectively improving the processing accuracy and finished product quality.

[0019] 2. The tape processing die-cutting device of the present invention, by setting a buffer component, when the die-cutting blade presses down to complete the die-cutting operation, the impact force of the downward pressure on the processing plate can drive the buffer rod to slide down along the support rod, and at the same time compress the spring. The elastic deformation of the spring absorbs and offsets the impact force generated during the die-cutting process, reduces the damage of the impact force to the overall structure of the device, extends the service life of the device, and also avoids the tape displacement caused by excessive impact force, further improving the accuracy of die-cutting processing.

[0020] 3. The tape processing and die-cutting device of the present invention allows for vertical adjustment of the position of the guide roller 1 via an adjustment component to adjust the tension of the tape. When adjustment is required, the adjustment plate is moved up and down within the chute by a moving component, thereby changing the height position of the guide roller 1. The sliding connection between the adjustment plate and the chute ensures that the guide roller 1 remains stable during adjustment and does not shift or shake, thus ensuring the stability of the tape during the guiding process.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 7 As shown in the figure, a tape processing and die-cutting device according to an embodiment of the present invention includes a worktable 1, with support blocks fixedly connected to the four corners of the bottom of the worktable 1, and handles fixedly connected to the front and rear surfaces of the worktable 1.

[0032] A processing plate 13 is provided at the top center of the workbench 1 via a buffer assembly. An L-shaped support frame 6 is fixedly connected to the rear of the top center of the workbench 1. A die-cutting assembly is provided on the L-shaped support frame 6. Guide assemblies are provided on both the left and right sides of the top of the workbench 1.

[0033] The guiding assembly includes two support plates 2, which are fixedly connected to the front and rear of the top of the workbench 1, respectively. A guide roller 3 is installed between the two support plates 2 via an adjusting assembly. A connecting plate 8 is fixedly connected to the opposite sides of each support plate 2, and a guide roller 14 is rotatably installed between the two connecting plates 8. During operation, the bottom of the support block is first aligned with a flat surface to ensure the device is stable. After stable placement, the tape to be die-cut, input via an external input mechanism, passes through the guiding assembly on the left side of the top of the workbench 1, and then enters the processing plate 13 through the guidance of the left-side guiding assembly. The guiding assembly can limit and guide the tape to be processed, ensuring that the tape aligns with the center of the processing plate 13 after being guided and limited. This ensures that the tape is processed without errors and improves the performance of the device. The guiding assembly guides the tape through the cooperation of guide roller 3 and guide roller 14. Guide roller 3 can be adjusted up and down via an adjustment component, allowing the tape to be adjusted to fit snugly against guide roller 3 and guide roller 14 when the tape is relaxed, thus avoiding any impact on the guiding effect. Next, the die-cutting assembly on the L-shaped support frame 6 processes the tape. During die-cutting, the processing plate 13 is cushioned by a buffer assembly, effectively improving the die-cutting effect and tape quality. Finally, the processed tape is output through the guide assembly on the right and collected by an external collection mechanism.

[0034] In a preferred embodiment of the present invention, a bidirectional screw 12 is rotatably mounted between the lower interiors of the two support plates 2. An internally threaded sleeve 24 is threaded to both the front and rear of the outer surface of the bidirectional screw 12. A limiting plate 15 is fixedly connected to the outer surface of the internally threaded sleeve 24. A guide roller 14 passes through the limiting plate 15. A motor 9 is fixedly connected to the front surface of the front support plate 2, and the output end of the motor 9 is fixedly connected to the front end of the bidirectional screw 12. During operation, the two limiting plates 15 positioned between the guide roller 1 and the guide roller 2 can limit the guide tape of the guiding assembly, ensuring that the tape is positioned between the guide roller 1 and the guide roller 2 during guidance. This allows the guided tape to precisely correspond to the center of the processing plate 13, thereby enabling the die-cutting assembly to perform its cutting function. There will be no error, and the distance between the two limiting plates 15 can be adjusted to accommodate tapes of different sizes. When adjustment is needed, the motor 9 is started, and the output end of the motor 9 drives the bidirectional screw 12 to rotate. Since the front and rear of the outer surface of the bidirectional screw 12 are threaded with internal thread sleeves 24, and the outer surface of the internal thread sleeves 24 is fixedly connected with the limiting plates 15, the rotation of the bidirectional screw 12 will cause the two internal thread sleeves 24 to move relative to or away from each other on the bidirectional screw 12, and the two limiting plates 15 can move relative to or away from each other, thereby adapting to the processing requirements of tapes of different sizes and improving the applicability of this device. At the same time, the limiting plates 15 do not contact the guide rollers 1 and 2, thus avoiding the limiting plates 15 from affecting the rotation of the guide rollers 1 and 2 during guidance.

[0035] In a preferred embodiment of the present invention, a limiting groove 23 is provided on the top of the workbench 1 corresponding to the bidirectional screw 12. Limiting blocks 22 are slidably connected to the front and rear of the limiting groove 23. The limiting blocks 22 are fixedly connected to the internal threaded sleeve 24. During operation, by setting the limiting groove 23 and the limiting blocks 22, the movement of the internal threaded sleeve 24 can be guided and limited, ensuring that the internal threaded sleeve 24 can move smoothly relative to or away from each other when the bidirectional screw 12 rotates. The sliding connection between the limiting blocks 22 and the limiting groove 23 effectively prevents the internal threaded sleeve 24 from shifting or rotating during movement, thereby improving the accuracy of the adjustment of the limiting plate 15.

[0036] In a preferred embodiment of the present invention, the adjusting assembly includes two slide grooves 21, which are respectively opened on opposite sides of the two support plates 2. An adjusting plate 17 is slidably connected inside the slide groove 21. The guide roller 3 is rotatably installed between the two adjusting plates 17. A moving assembly is provided between the two adjusting plates 17 and the two support plates 2. During operation, the position of the guide roller 3 can be adjusted up and down by the adjusting assembly to adjust the tension of the tape. When adjustment is required, the moving assembly drives the adjusting plate 17 to slide up and down in the slide groove 21, thereby changing the height position of the guide roller 3. The sliding connection between the adjusting plate 17 and the slide groove 21 ensures that the guide roller 3 remains stable during the adjustment process and does not shift or shake, thereby ensuring the stability of the tape during the guiding process.

[0037] In a preferred embodiment of the present invention, a through guide groove 19 is provided on both the left and right sides of the slide groove 21. A guide block 18 is slidably connected inside the guide groove 19, and the guide block 18 is fixedly connected to the adjusting plate 17. During operation, by setting the guide groove 19 and the guide block 18, the stability of the adjusting plate 17 when sliding in the slide groove 21 can be further enhanced. The cooperation between the guide block 18 and the guide groove 19 can effectively prevent the adjusting plate 17 from tilting or getting stuck during the up and down movement, thereby ensuring that the guide roller 3 always remains horizontal when the height is adjusted.

[0038] In a preferred embodiment of the present invention, the moving component includes two inner grooves 25, which are respectively opened above the interior of two support plates 2. A threaded rod 28 is rotatably mounted between the inner groove 25 and the sliding groove 21. A driving component is provided between the two threaded rods 28. An internal threaded sleeve 20 is threadedly connected to the lower outer surface of the threaded rod 28, and the internal threaded sleeve 20 is fixedly connected to the adjusting plate 17. During operation, the moving component can precisely control the up-and-down movement of the guide roller 3 to meet the guiding requirements of tapes of different thicknesses. When adjustment is needed... When the height of guide roller 3 is adjusted, the drive assembly is activated. The drive assembly drives the two threaded rods 28 to rotate synchronously. Since the threaded rod 28 has an internal threaded sleeve 20 connected to the lower surface of its outer surface, and the internal threaded sleeve 20 is fixedly connected to the adjusting plate 17, the rotation of the threaded rod 28 is converted into the linear motion of the internal threaded sleeve 20. This causes the two adjusting plates 17 to move up and down smoothly together, making the adjustment of guide roller 3 more convenient and stable. This design not only enables precise adjustment of the height of guide roller 3, but also ensures the stability and reliability of the adjustment process.

[0039] In a preferred embodiment of the present invention, the driving assembly includes a rotating rod 26, which is rotatably mounted inside an inner groove 25. A second motor 31 is fixedly mounted inside the inner groove 25, and the output end of the second motor 31 is fixedly connected to the rotating rod 26. A second helical gear 29 is fixedly connected to the outer surface of the rotating rod 26. A first helical gear 27 is fixedly connected to the top of the threaded rod 28, and the first helical gear 27 meshes with the second helical gear 29. The opposite ends of the two rotating rods 26 extend to the outside of the support plate 2 and are fixedly connected to a connecting rod 30. During operation, the height of the guide roller 3 can be precisely controlled by the driving assembly. When adjustment is required... When the motor 21 is started, its output drives the front rotating rod 26 to rotate. The helical gear 29 fixed on the outer surface of the rotating rod 26 rotates accordingly and meshes with the helical gear 27 fixed at the top of the threaded rod 28, thereby transmitting the rotational motion to the threaded rod 28. The rotation of the threaded rod 28 causes the internal threaded sleeve 20 connected to it to produce linear motion, which in turn drives the adjusting plate 17 to move up and down along the slide groove 21. The two rotating rods 26 are linked synchronously through the connecting rod 30 to ensure that the rotation of the threaded rods 28 on both sides is consistent, thereby realizing the synchronous adjustment of the height of the two ends of the guide roller 3, avoiding the problem of tilting of the guide roller 3 due to uneven adjustment, and further improving the adjustment efficiency.

[0040] In a preferred embodiment of the present invention, the die-cutting assembly includes a hydraulic cylinder 5, which is fixedly installed on the top of an L-shaped support frame 6. The output end of the hydraulic cylinder 5 passes through the upper part of the L-shaped support frame 6 and is fixedly installed with a die-cutting blade 7. Guide rods 4 are fixedly connected to the four corners of the top of the die-cutting blade 7, and the top of the guide rods 4 passes through the top of the L-shaped support frame 6. During operation, the hydraulic cylinder 5 is activated, and its output end drives the die-cutting blade 7 to move downward. The die-cutting blade 7 remains vertical and stable under the guidance of the guide rods 4, ensuring that the die-cutting process is accurate and error-free. The cooperation between the guide rods 4 and the L-shaped support frame 6 effectively prevents the die-cutting blade 7 from deviating or shaking during the downward pressing process, thereby improving the die-cutting quality. After the die-cutting blade 7 contacts the tape on the processing plate 13, it completes the die-cutting process of the tape.

[0041] In a preferred embodiment of the present invention, the buffer assembly includes four buffer rods 16, which are fixedly connected to the four corners of the bottom of the processing plate 13. Each buffer rod 16 has a support rod 10 at its bottom end and is slidably connected to the support rod 10. Springs 11 are fixedly connected between the four corners of the top of the processing plate 13 and the top of the worktable 1. The springs 11 are sleeved around the buffer rods 16 and the support rods 10. During operation, when the die-cutting assembly die-cuts the tape, the processing plate 13 is subjected to downward pressure. At this time, the buffer rods 16 slide inside the support rods 10, and the springs 11 are compressed. The elastic deformation of the springs 11 absorbs part of the impact force, effectively reducing the vibration and impact generated during the die-cutting process, thereby protecting the processing plate 13 and the tape from damage and improving the die-cutting accuracy and tape quality. Furthermore, after die-cutting, the buffer assembly can use the restoring force of the springs 11 to quickly reset the processing plate 13, ensuring the efficiency and stability of continuous processing.
