Description

Technical Field

[0001] This application relates to the technical field of die-cutting machines, and in particular to a self-cleaning anti-tangling component for a die-cutting machine. Background Technology

[0002] Die-cutting machines are core processing equipment in industries such as packaging, printing, and electronics. They primarily use dies to precisely cut, creasing, or shape flexible substrates such as paper, film, leather, and metal foil. Their processing precision and stability directly determine the quality of the final product. In actual production, materials can easily become entangled on the die-cutting machine's blades, leading to machine downtime, reduced production efficiency, and even potential equipment damage.

[0003] Currently, during the operation of die-cutting machines, materials are prone to getting tangled on the die-cutting blades, which can lead to machine downtime, reduced production efficiency, and even damage to the equipment. Utility Model Content

[0004] The purpose of this application is to provide a self-cleaning anti-tangling component for a die-cutting machine, which has the advantages of easily cleaning up the material tangled on the die-cutting blade, preventing the material tangled on the die-cutting blade from affecting the operation of the equipment, and solving the problem that the material is easy to tangle on the die-cutting blade during the current die-cutting machine operation, which will lead to equipment downtime, reduced production efficiency, and even damage to the equipment.

[0005] This application provides a self-cleaning anti-winding component for a die-cutting machine, employing the following technical solution: A self-cleaning anti-winding component for a die-cutting machine includes a base. A die-cutting component is disposed above the base. The die-cutting component includes a die-cutting roller and an impression roller. The die-cutting roller is located below the impression roller. A driving mechanism is disposed at the ends of the die-cutting roller and the impression roller. The driving mechanism is fixedly disposed on the top of the base by a fixing frame. A cleaning component is disposed below the die-cutting roller. The cleaning component includes a rotating roller. A connecting rubber is wound around the outer surface of the middle portion of the rotating roller. A large number of cleaning brushes are fixedly disposed on the outer surface of the middle portion of the connecting rubber. The rotating roller is rotatably mounted on the inner side of the support frame via a rotating rod. A motor is fixedly mounted at one end of the top of the support frame, and one end of the motor output shaft is fixedly connected to one end of the rotating rod at one end of the rotating roller. The rotation direction of the rotating roller is opposite to that of the die-cutting roller. A pneumatic push rod is fixedly mounted on the top of the base, and the output end of the pneumatic push rod is fixedly mounted on the bottom of the support frame. A detection sensor is provided on one side of the die-cutting roller, and the detection sensor is fixedly mounted on the top of the base via a fixing bracket. A control host is fixedly mounted on the top of the base, and the control host is electrically connected to the motor, the pneumatic push rod, and the detection sensor.

[0006] By adopting the above technical solution, when the detection sensor detects material wrapped around the outer surface of the middle part of the die-cutting roller, the pneumatic push rod pushes the cleaning component to move upward through the support frame, the motor works, and drives the rotating roller to rotate. When the rotating roller rotates, it drives the cleaning brush to clean the material wrapped around the die-cutting roller, so that the material is separated from the die-cutting roller. This achieves convenient cleaning of the material wrapped around the die-cutting tool and avoids the material wrapped around the die-cutting tool from affecting the operation of the equipment.

[0007] Preferably, a fixing groove is formed on the outer surface of the middle part of the rotating roller, and the two ends of the connecting rubber are inserted into the fixing groove in a side-to-side fit. Two receiving cavities are formed on the two side walls inside the fixing groove, and two clamping plates are slidably arranged inside the two receiving cavities. The two clamping plates are located on both sides of the fit between the two ends of the connecting rubber.

[0008] By adopting the above technical solution, the connecting rubber and cleaning brush can be easily removed from the rotating roller for replacement by inserting both ends of the connecting rubber into the fixing groove. At the same time, the connecting rubber installed on the rotating roller can be fixed by the cooperation of two clamping plates to prevent the connecting rubber from loosening when the rotating roller rotates, so that the cleaning brush can stably clean the material wrapped on the die-cutting roller.

[0009] Preferably, each end of the rotating roller is provided with two extrusion plates, which are located on opposite sides of the corresponding ends of the two clamping plates. The side surfaces of the extrusion plates abut against the side surfaces of the clamping plates. Each end of the rotating roller is provided with a threaded rod, and the inner walls of the middle portions of the two corresponding extrusion plates are threaded to the outer surfaces of the middle portions of the threaded rod. The two ends of the threaded rod are rotatably mounted on the ends of the rotating roller via two support plates. The thread directions of the outer surfaces of the middle portions of the threaded rod are opposite, and the thread directions of the outer surfaces of the middle portions of the threaded rod are adapted to the thread directions of the inner walls of the middle portions of the two corresponding extrusion plates.

[0010] By adopting the above technical solution, rotating the threaded rod can drive the corresponding two extrusion plates to move and adjust the distance between the two extrusion plates. When the two extrusion plates are close to each other, they can clamp the two clamping plates, thereby enabling the clamping plates to stably clamp and fix the connecting rubber in the fixing groove. When the two extrusion plates are far apart, the clamping plates can be released, thereby releasing the clamping plates from the connecting rubber, making it easy to remove the connecting rubber from the rotating roller.

[0011] Preferably, both ends of the rotating roller are fixedly provided with limit rods by fixing plates, and the inner wall of one end of the extrusion plate is slidably disposed on the outer surface of the middle part of the limit rod.

[0012] By adopting the above technical solution, the inner wall of one end of the extrusion plate slides on the outer surface of the middle part of the limiting rod, which can limit the angle when the extrusion plate moves, prevent the extrusion plate from swinging when the threaded rod rotates, and enable the threaded rod to stably drive the extrusion plate to move.

[0013] Preferably, an anti-slip pad is fixedly provided on the side of the clamping plate near the connecting rubber.

[0014] By adopting the above technical solution, the anti-slip pad can increase the friction between the clamping plate and the connecting rubber, so that the clamping plate can stably clamp the connecting rubber through the anti-slip pad, preventing the connecting rubber from falling off between the two clamping plates as it rotates with the rotating roller.

[0015] Preferably, two pads are fixedly provided on opposite sides of the corresponding ends of the two clamping plates, and the two corresponding pads abut against each other.

[0016] By adopting the above technical solution, the pad block can support the corresponding ends of the two clamping plates, preventing the clamping plates from being excessively squeezed by the extrusion plate, which could cause the clamping plates to bend and break.

[0017] Preferably, a worm gear is fixedly provided at the end of the threaded rod, and a worm is provided on one side of the worm gear. The worm gear meshes with the worm, and the worm is rotatably mounted at the end of the rotating roller via a connecting frame.

[0018] By adopting the above technical solution, the threaded rod can be easily driven by rotating the worm gear and worm wheel. At the same time, the self-locking between the worm gear and worm wheel can prevent the threaded rod from rotating back, thereby ensuring that the extrusion plate stably clamps the clamping plate.

[0019] Preferably, a plurality of sliding rods are fixedly provided on one side of the inner wall of the receiving cavity, and the outer surface of the middle part of the sliding rods is slidably connected to the inner wall of the middle part of the clamping plate.

[0020] By adopting the above technical solution, the inner wall of the middle part of the clamping plate slides on the outer surface of the middle part of the slide rod, which can limit the trajectory of the clamping plate in the receiving cavity, prevent the clamping plate from sliding out from the opening at the end of the receiving cavity, and make the clamping plate only move along the axial direction of the slide rod, thus avoiding the clamping plate tilting or deviating during the movement.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This self-cleaning anti-tangling component for a die-cutting machine detects material tangling on the outer surface of the die-cutting roller via a detection sensor. A pneumatic pusher then moves the cleaning component upwards via a support frame. A motor operates, driving a rotating roller to rotate. This rotation causes a cleaning brush to clean the material tangled on the die-cutting roller, separating the material from the roller. This allows for convenient cleaning of material tangled on the die-cutting blade, preventing it from affecting the machine's operation. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: A self-cleaning anti-tangling component for a die-cutting machine, please refer to... Figure 1 , Figure 2 and Figure 3The system includes a base 1, with a die-cutting assembly 2 above the base 1. The die-cutting assembly 2 includes a die-cutting roller 201 and an impression roller 202. The die-cutting roller 201 is located below the impression roller 202. A drive mechanism 3 is provided at the ends of the die-cutting roller 201 and the impression roller 202. The drive mechanism 3 is fixedly mounted on the top of the base 1 by a fixing frame. A cleaning assembly 4 is provided below the die-cutting roller 201. The cleaning assembly 4 includes a rotating roller 401. A connecting rubber sheet 402 is wrapped around the outer surface of the middle part of the rotating roller 401. A large number of cleaning brushes 403 are fixedly mounted on the outer surface of the middle part of the connecting rubber sheet 402. The rotating roller 401 is rotatably mounted inside the support frame 16 by a rotating rod. On one side, a motor 17 is fixedly installed at one end of the top of the support frame 16. One end of the output shaft of the motor 17 is fixedly connected to one end of the rotating rod of the rotating roller 401. The rotation direction of the rotating roller 401 is opposite to the rotation direction of the die-cutting roller 201. A pneumatic push rod 18 is fixedly installed at the top of the base 1. The output end of the pneumatic push rod 18 is fixedly installed at the bottom of the support frame 16. A detection sensor 20 is provided on one side of the die-cutting roller 201. The detection sensor 20 is fixedly installed at the top of the base 1 through a fixing frame. A control host 19 is fixedly installed at the top of the base 1. The control host 19 is electrically connected to the motor 17, the pneumatic push rod 18 and the detection sensor 20.

[0026] Please see Figure 2 , Figure 3 and Figure 4 A fixing groove 5 is provided on the outer surface of the middle part of the rotating roller 401. The two ends of the connecting rubber 402 are inserted into the fixing groove 5 with their sides touching each other. Two receiving cavities 6 are provided on the two side walls inside the fixing groove 5. Two clamping plates 7 are slidably arranged inside the two receiving cavities 6. The two clamping plates 7 are located on both sides of the touching ends of the connecting rubber 402. By inserting the two ends of the connecting rubber 402 into the fixing groove 5, the connecting rubber 402 and the cleaning brush 403 can be easily removed from the rotating roller 401 for replacement. At the same time, the two clamping plates 7 cooperate with each other to clamp the connecting rubber 402 in the fixing groove 5, which can fix the connecting rubber 402 installed on the rotating roller 401 and prevent the connecting rubber 402 from loosening when the rotating roller 401 rotates. This allows the cleaning brush 403 to stably clean the material wrapped on the die-cutting roller 201.

[0027] Please see Figure 2 , Figure 4 and Figure 5Two extrusion plates 8 are provided at both ends of the rotating roller 401. The two extrusion plates 8 are located on opposite sides of the corresponding ends of the two clamping plates 7. The side surfaces of the extrusion plates 8 abut against the side surfaces of the clamping plates 7. Threaded rods 9 are provided at both ends of the rotating roller 401. The inner walls of the middle sections of the two corresponding extrusion plates 8 are threaded to the outer surfaces of the middle sections of the threaded rods 9. The two ends of the threaded rods 9 are rotatably mounted on the ends of the rotating roller 401 via two support plates. The thread directions of the outer surfaces of the middle sections of the threaded rods 9 are opposite. The threads on the inner walls of the two extrusion plates 8 are aligned. By rotating the threaded rod 9, the corresponding two extrusion plates 8 can be moved, and the distance between the two extrusion plates 8 can be adjusted. When the two extrusion plates 8 are close to each other, they can clamp the two clamping plates 7, thereby enabling the clamping plates 7 to stably clamp and fix the connecting rubber 402 in the fixing groove 5. When the two extrusion plates 8 are far apart, the clamping of the clamping plates 7 can be released, thereby releasing the clamping plates 7 from clamping the connecting rubber 402, and the connecting rubber 402 can be easily removed from the rotating roller 401.

[0028] Please see Figure 2 and Figure 4 Both ends of the rotating roller 401 are fixed with limit rods 13 by fixing plates. The inner wall of one end of the extrusion plate 8 is slidably disposed on the outer surface of the middle part of the limit rod 13. The inner wall of one end of the extrusion plate 8 slides on the outer surface of the middle part of the limit rod 13, which can limit the angle when the extrusion plate 8 moves, and prevent the extrusion plate 8 from swinging when the threaded rod 9 rotates, so that the threaded rod 9 can stably drive the extrusion plate 8 to move.

[0029] Please see Figure 4 and Figure 5 An anti-slip pad 14 is fixedly provided on the side of the clamping plate 7 near the connecting rubber 402. The anti-slip pad 14 can increase the friction between the clamping plate 7 and the connecting rubber 402, so that the clamping plate 7 can stably clamp the connecting rubber 402 through the anti-slip pad 14, preventing the connecting rubber 402 from falling off between the two clamping plates 7 as the rotating roller 401 rotates.

[0030] Please see Figure 2 , Figure 3 and Figure 5 Two pads 10 are fixedly provided on opposite sides of the corresponding ends of the two clamping plates 7. The two corresponding pads 10 abut against each other. The pads 10 can support the corresponding ends of the two clamping plates 7, and prevent the clamping plate 7 from being over-compressed by the compression plate 8, which would cause the clamping plate 7 to bend and break.

[0031] Please see Figure 4 and Figure 5Multiple sliding rods 15 are fixedly installed on one side of the inner wall of the receiving cavity 6. The outer surface of the middle part of the sliding rod 15 is slidably connected to the inner wall of the middle part of the clamping plate 7. The inner wall of the middle part of the clamping plate 7 slides on the outer surface of the middle part of the sliding rod 15, which can restrict the trajectory of the clamping plate 7 in the receiving cavity 6, prevent the clamping plate 7 from sliding out from the opening at the end of the receiving cavity 6, and make the clamping plate 7 only move along the axial direction of the sliding rod 15, so as to avoid the clamping plate 7 tilting or deviating during the movement.

[0032] Example 2: A self-cleaning anti-tangling component for a die-cutting machine, please refer to... Figure 2 , Figure 3 and Figure 4 A worm wheel 11 is fixedly installed at the end of the threaded rod 9. A worm 12 is provided on one side of the worm wheel 11. The worm wheel 11 meshes with the worm 12. The worm 12 is rotatably installed at the end of the rotating roller 401 through the connecting frame. By rotating the worm 12 in conjunction with the worm wheel 11, the threaded rod 9 can be easily driven. At the same time, the self-locking between the worm 12 and the worm wheel 11 can prevent the threaded rod 9 from rotating, thereby ensuring that the extrusion plate 8 can stably clamp the clamping plate 7.

[0033] The implementation principle of this application embodiment is as follows: The drive mechanism 3 drives the die-cutting roller 201 and the impression roller 202 to rotate. The material passes between the die-cutting roller 201 and the impression roller 202. The die-cutting roller 201 and the impression roller 202 cooperate to die-cut the material. When the detection sensor 20 detects that the material is wrapped around the cutter of the die-cutting roller 201, the detection sensor 20 sends a signal to the control host 19. The control host 19 controls the motor 17 to pneumatically drive the rotating roller 401 to rotate in the opposite direction to the rotation of the die-cutting roller 201. At the same time, the control host 19 controls the pneumatic push rod 18 to work. The pneumatic push rod 18 pushes the support frame 16 to move upward, so that the support frame 16 drives the rotating roller 401 to move upward. The cleaning brush 403 on the outside of the rotating roller 401 cleans the material wrapped around the cutter of the die-cutting roller 201. When the cleaning brush 403 is worn and needs to be replaced, the worm gear 12 is rotated to drive the worm wheel. Rotating the worm gear 11 causes the threaded rod 9 to rotate. As the threaded rod 9 rotates, it causes the two extrusion plates 8 to move in opposite directions, releasing them from clamping the ends of the two clamping plates 7. This, in turn, releases the clamping plates 7 from clamping the connecting rubber 402, allowing both ends of the connecting rubber 402 to be pulled out of the fixing groove 5. The connecting rubber 402 and the cleaning brush 403 are then removed from the rotating roller 401. The connecting rubber 402 with the new cleaning brush 403 is wound around the rotating roller 401, and both ends of the connecting rubber 402 are inserted into the fixing groove 5. Rotating the worm gear 12 causes the worm gear 11 to rotate the threaded rod 9, causing the threaded rod 9 to move the two extrusion plates 8 in opposite directions, clamping the ends of the two clamping plates 7. This, in conjunction with the anti-slip pad 14, clamps and fixes the connecting rubber 402 in the fixing groove 5, completing the replacement of the cleaning brush 403.
