Description

Technical Field

[0001] This utility model relates to the field of double-sided tape processing, and more specifically, to a cutting device for double-sided tape. Background Technology

[0002] Double-sided tape is a roll of adhesive tape made of paper, cloth, plastic film, elastomer-type pressure-sensitive adhesive, or resin-type pressure-sensitive adhesive. Its characteristic is that the tape has a protective effect on both sides.

[0003] In the prior art, such as Chinese patent "CN223084961U", a "cutting device for processing double-sided adhesive" is proposed, which includes an operating table, an auxiliary mechanism installed on the upper part of the operating table, and a cutting mechanism.

[0004] However, although the aforementioned patent achieves double-sided tape cutting through the cooperation of the operating table, auxiliary mechanism and cutting mechanism, the design of its cutting mechanism is only for multi-segment cutting scenarios. It can only perform batch segment cutting of double-sided tape using multiple preset sets of blades. It cannot switch to single-segment cutting mode according to actual needs. When the production scenario requires single-segment fixed-length cutting of double-sided tape, such as custom processing of large-size double-sided tape, the device needs to be stopped, multiple sets of blades need to be disassembled and the equipment structure needs to be readjusted. The operation process is cumbersome and time-consuming, and it cannot adapt to the flexible processing needs of small batches and multiple specifications, resulting in low production efficiency and difficulty in covering the full-scenario needs of double-sided tape processing. Utility Model Content

[0005] 1. Technical problems to be solved In view of the problems existing in the prior art, the purpose of this utility model is to provide a cutting device for double-sided tape to solve the problems mentioned in the background art.

[0006] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0007] A cutting device for double-sided tape includes a mounting frame. A first screw is rotatably connected to the lower part of the mounting frame. A movable plate is threadedly connected to the outer wall of the first screw. The movable plate is slidably connected to the lower part of the mounting frame. A first mounting plate and a second mounting plate are slidably connected to the upper part of the movable plate. A rack is fixedly connected to one side of the first mounting plate and one side of the second mounting plate. A gear is rotatably connected to the middle of the upper part of the movable plate. The two sides of the outer wall of the gear mesh with the two racks respectively. A first blade is mounted on the upper part of the first mounting plate.

[0008] Furthermore, a hydraulic cylinder is rotatably connected above the movable plate, and the output end of the hydraulic cylinder is rotatably connected to the lower part of the first mounting plate.

[0009] Furthermore, a fixing plate is fixedly connected above the second mounting plate, and multiple sliders are slidably connected inside the fixing plate, with protrusions fixedly connected above each of the sliders.

[0010] Furthermore, a second blade is fixedly connected to one end of each slider.

[0011] Furthermore, a sliding plate is slidably connected above the fixed plate, and the sliding direction of the sliding plate is perpendicular to the sliding direction of the slider.

[0012] Furthermore, the surface of the sliding plate is provided with multiple inclined grooves, and the protrusion is slidably connected inside the inclined grooves.

[0013] Furthermore, a No. 1 motor is fixedly connected to the top of the fixed plate, and a No. 2 screw is fixedly connected to the output end of the No. 1 motor. The outer wall of the No. 2 screw is threadedly connected to the top of the sliding plate.

[0014] Furthermore, a winding roller is rotatably connected above the mounting frame.

[0015] Furthermore, a second motor is mounted on the outside of the mounting frame, and the output end of the second motor is fixedly connected to one end of the winding roller.

[0016] Furthermore, a No. 3 motor is mounted on the outside of the mounting bracket, and the output end of the No. 3 motor is fixedly connected to one end of the No. 1 screw.

[0017] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: In this invention, the device uses a gear and rack meshing linkage structure to achieve avoidance and coordination between the first and second blades. When single-segment cutting is required, the hydraulic cylinder pushes the first mounting plate closer to the winding roller, while simultaneously moving the second mounting plate away from the cutting area to avoid interference from the second blade. When multi-segment cutting is required, the reverse operation can be performed to allow the second blade to approach and the first blade to avoid. The cutting mode can be switched without disassembling or replacing the blade assembly, adapting to different scenarios from single-segment customization to multi-segment batch processing, especially meeting the production needs of small batches and multiple specifications, thus expanding the applicability of the equipment.

[0018] In this invention, the second blade is linked to the inclined groove of the sliding plate by the slider, the protrusion and the first motor driving the second screw to drive the sliding plate to slide, and the spacing between multiple sliders is adjusted simultaneously, thereby changing the cutting width of the second blade. Compared with the traditional method of adjusting the blades one by one, there is no need to stop the machine to replace parts, and the adjustment efficiency is significantly improved.

[0019] In this invention, the fixed plate integrates components such as the slider, the second blade, and the sliding plate. The winding roller is installed close to the second motor, and the first screw is installed close to the third motor. The overall structure of the equipment is compact, saving installation space. Lateral adjustment does not require a separate drive component for the second mounting plate, reducing the number of equipment parts, manufacturing costs, and the difficulty of later maintenance.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] In some embodiments, please refer to Figures 1-5 A cutting device for double-sided tape includes a mounting frame 1. A screw 12 is rotatably connected to the lower part of the mounting frame 1. A movable plate 13 is threadedly connected to the outer wall of the screw 12. The movable plate 13 is slidably connected to the lower part of the mounting frame 1. A mounting plate 14 and a mounting plate 15 are slidably connected to the upper part of the movable plate 13. A rack 17 is fixedly connected to one side of the mounting plate 14 and one side of the mounting plate 15. A gear 16 is rotatably connected to the middle part of the upper part of the movable plate 13. The two sides of the outer wall of the gear 16 mesh with the two racks 17 respectively. A hydraulic cylinder 19 is rotatably connected to the upper part of the movable plate 13. The output end of the hydraulic cylinder 19 is rotatably connected to the lower part of the mounting plate 14. A blade 18 is mounted on the upper part of the mounting plate 14.

[0026] In this embodiment, a threaded transmission structure is formed between the first screw 12 and the moving plate 13 below the mounting frame 1. Compared with the traditional manual adjustment or cylinder push method, the threaded transmission has the advantages of "no slippage and high displacement accuracy". When the third motor 29 drives the first screw 12 to rotate, the moving plate 13 can move smoothly along the sliding trajectory below the mounting frame 1, which can accurately adapt to the cutting requirements of double-sided tapes of different widths and specifications, and avoid tape waste caused by position deviation. Mounting plate 14 and mounting plate 15 above the moving plate 13 are connected by rack 17 and gear 16 to form a "synchronous reverse movement" structure. When the hydraulic cylinder 19 pushes mounting plate 14 to slide along the moving plate 13, the rack 17 on one side of mounting plate 14 will drive gear 16 to rotate, and then pull mounting plate 15 to slide in the opposite direction through the rack 17 on the other side. This linkage structure does not require separate adjustment of the two mounting plates and can quickly adjust the lateral spacing between the components on the first blade 18 and mounting plate 15. The adjustment efficiency is significantly improved compared with the traditional independent adjustment method, and the spacing consistency error is small, ensuring the uniformity of multiple tape cutting.

[0027] In some embodiments, please refer to Figures 1-5A cutting device for double-sided tape is provided. A fixed plate 2 is fixedly connected above a second mounting plate 15. Multiple sliders 21 are slidably connected inside the fixed plate 2. Each slider 21 has a protrusion 22 fixedly connected above it. A second blade 23 is fixedly connected to one end of each slider 21. A sliding plate 26 is slidably connected above the fixed plate 2. The sliding direction of the sliding plate 26 is perpendicular to the sliding direction of the sliders 21. Multiple inclined grooves 27 are formed on the surface of the sliding plate 26. The protrusions 22 are slidably connected inside the inclined grooves 27. A first motor 24 is fixedly connected above the fixed plate 2. A second screw 25 is fixedly connected to the output end of the first motor 24. The outer wall of the second screw 25 is threadedly connected to the top of the sliding plate 26. A winding roller 11 is rotatably connected above the mounting frame 1. A second motor 28 is mounted outside the mounting frame 1. The output end of the second motor 28 is fixedly connected to one end of the winding roller 11. A third motor 29 is mounted outside the mounting frame 1. The output end of the third motor 29 is fixedly connected to one end of the first screw 12.

[0028] In this embodiment, the winding roller 11 is used to wind double-sided tape. Multiple sliders 21 are slidably connected inside the fixing plate 2 above the second mounting plate 15. Each slider 21 has a second blade 23 fixed at one end, and the slider 21 slides in cooperation with the inclined groove 27 of the sliding plate 26 through the protrusion 22. When the first motor 24 drives the second screw 25 to rotate, the sliding plate 26 slides along the fixing plate 2, and the inclined groove 27 will synchronously drive multiple sliders 21 to slide along the inside of the fixing plate 2 through the protrusion 22. Since the sliding direction of the sliding plate 26 and the slider 21 is perpendicular, the spacing between adjacent second blades 23 can be quickly adjusted. When the spacing between adjacent second blades 23 is adjusted to a suitable position, the first motor 24 can be stopped. Multiple sliders 21 are adjusted in linkage through the inclined groove 27 of the same sliding plate 26, which can ensure that the spacing adjustment of all second blades 23 remains synchronous.

[0029] Working principle: Double-sided tape is wrapped around the outer wall of the wrapping roller 11. Then, the second motor 28 is started to drive the wrapping roller 11 to rotate. When only a section of double-sided tape needs to be cut, the first blade 18 is activated first. At the same time, the second blade 23 is moved away from the wrapping roller 11 through the meshing structure of the gear 16 and the rack 17.

[0030] The hydraulic cylinder 19 above the moving plate 13 is activated, and its output end pushes the first mounting plate 14 to slide along the top of the moving plate 13 toward the winding roller 11, that is, to move toward the cutting area. Because the rack 17 on one side of the first mounting plate 14 meshes with the gear 16 in the middle of the moving plate 13, and the other side of the gear 16 meshes with the rack 17 of the second mounting plate 15, the sliding of the first mounting plate 14 will drive the gear 16 to rotate, thereby pulling the second mounting plate 15 to slide in the opposite direction away from the winding roller 11. During this process, the first blade 18 above the first mounting plate 14 moves closer to the cutting area synchronously with the mounting plate, while the second blade 23 on the fixed plate 2 above the second mounting plate 15 moves away from the cutting area with the mounting plate to avoid the second blade 23 interfering with the single-segment cutting. At the same time, the output pressure is adjusted by the hydraulic cylinder 19 to control the cutting pressure of the first blade 18. Combined with the third motor 29 driving the first screw 12 to move the moving plate 13 to slide, the longitudinal cutting position of the first blade 18 is adjusted until the single-segment cutting requirements are met. When multiple sections of double-sided tape need to be cut, multiple second blades 23 are used first, while the meshing structure of gear 16 and rack 17 keeps the first blade 18 away from the winding roller 11.

[0031] Start the hydraulic cylinder 19, and its output end pulls the first mounting plate 14 to slide along the upper part of the moving plate 13 away from the winding roller 11. Through the meshing transmission of the rack 17 and the gear 16, the second mounting plate 15 is pushed to slide towards the winding roller 11, so that the second blade 23 on the fixed plate 2 is close to the cutting area and the first blade 18 is away from the cutting area. Then, the first motor 24 is started, and its output end drives the second screw 25 to rotate, driving the sliding plate 26 to slide along the fixed plate 2 perpendicular to the slider 21. The inclined groove 27 of the sliding plate 26 drives multiple sliders 21 to slide synchronously along the inside of the fixed plate 2 through the protrusion 22, adjusting the spacing between adjacent second blades 23 to adapt to the width requirements of multi-segment cutting; then, the third motor 29 adjusts the longitudinal position of the moving plate 13, locks the cutting position of the second blade 23, and completes the setting of multi-segment cutting parameters.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
