Description

Technical Field

[0001] This invention belongs to the field of extrusion device technology, specifically a rolling device for metal sheets. Background Technology

[0002] Metal sheet rolling devices, often called grooving machines, are used to press metal materials to form specific shapes or grooves. They are widely used in industries such as construction, automobiles, and aerospace. They are extrusion devices used to manufacture various metal components and metal sheets. Through extrusion processing, the microstructure of the metal changes, which can usually improve the strength and hardness of the material. Extrusion processing enables rapid mass production and is suitable for large-scale manufacturing.

[0003] For example, a Chinese patent with announcement number CN215467315U discloses a metal sheet rolling and folding device, including an outer box, an inner storage cavity, and a main body of the rolling and folding device inside the storage cavity. This utility model features an outer box, a storage cavity, a lifting structure, a limiting groove, an upper cover, and a limiting block, enabling the main body of the rolling and folding device to extend out of the storage cavity during rolling and folding and to be stored within the storage cavity when not rolling and folding. This does not affect the normal rolling and folding operation of the device. Furthermore, when not rolling and folding, it effectively prevents external moisture from causing rust on the main body of the rolling and folding device or external dust from affecting its structural operation. It provides good waterproof and dustproof performance, reducing the frequency of maintenance and extending the service life of the main body of the rolling and folding device.

[0004] However, existing metal sheet extrusion devices can only extrude at specific locations when extruding sheet metal, which is not flexible enough and makes it difficult to adjust the position of the groove. This results in certain limitations when performing extrusion and grooving processes on different locations of metal sheets. These limitations not only affect the processing efficiency but also restrict the adaptability to complex workpiece shapes.

[0005] Therefore, the present invention provides a rolling device for metal sheets. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the problem of inconvenient quick adjustment of the pressure groove position, this invention proposes a rolling device for metal sheets.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A rolling device for metal sheets, comprising a worktable, a housing fixedly mounted on the worktable, a controller provided on the worktable, a support roller inside the worktable, an extrusion roller inside the worktable and positioned above the support roller, two sets of annular dies fixedly mounted on the extrusion roller, extrusion dies symmetrically arranged around the extrusion roller, a through groove provided inside the extrusion roller, a connecting plate fixedly mounted on the inner ring of the extrusion die, a threaded ring fixedly mounted inside the connecting plate, and a threaded screw rotatably mounted inside the through groove, the threaded screw being connected to the threaded thread... The extrusion rollers are connected by a ring thread. A mounting box is symmetrically arranged inside the extrusion roller, and a power motor is fixedly installed inside the mounting box. The output end of the power motor is fixedly connected to one end of a corresponding threaded screw. A battery assembly is installed inside the power motor and is electrically connected to the power motor. Heat dissipation holes are provided inside the extrusion rollers and are connected to the mounting boxes. A power assembly for driving the support rollers and extrusion rollers to rotate is provided on the worktable. A storage assembly is provided inside the worktable. A guide assembly is provided inside the connecting plate. Square frames are symmetrically installed on the connecting plate, and a wind-powered assembly is provided inside the square frames. A cleaning assembly is provided on the extrusion die.

[0008] By adopting the above technical solution, the metal sheet to be processed is manually picked up, and one end of the metal sheet is inserted between the extrusion roller and the support roller. The annular die and the extrusion die then contact the surface of the metal sheet. Through the cooperation of the extrusion roller, the metal sheet can be extruded to create grooves. This enhances the structural strength, rigidity, and aesthetics of the metal sheet, increases its resistance to bending and torsion, and makes it less prone to deformation under stress. The annular die and the extrusion die can be used to perform a grooving process on the metal sheet. The power motor is a remote-controlled motor. When the position of the grooving on the metal sheet is adjusted as needed, the power motor will drive the threaded screw to rotate. When the threaded screw rotates, it will drive the connecting plate to move through the engagement of the threaded ring. The guide component will guide the connecting plate to move smoothly. When the connecting plate moves, the position of the extrusion die can be adjusted, which facilitates the grooving process at different positions on the metal sheet.

[0009] Preferably, the storage component includes a discharge trough, a sliding trough, and a waste trough. The sliding trough is disposed inside the workbench, the waste trough is disposed inside the sliding trough, and the discharge trough is disposed inside the workbench, and the discharge trough is connected to the sliding trough. An anti-deviation groove is provided on the workbench.

[0010] By adopting the above technical solution, after the debris falls onto the worktable, it enters the discharge chute and slides into the waste chute for collection. When cleaning the collected debris, the waste chute can be pulled out of the sliding chute, thereby cleaning the debris collected inside the waste chute.

[0011] Preferably, the power assembly includes a drive motor, which is symmetrically mounted on the worktable. Support shafts are fixedly mounted at both ends of the support roller and the extrusion roller. A through-tube corresponding to the support shaft is fixedly mounted inside the worktable. The support shaft passes through the through-tube, and the output ends of the two sets of drive motors are respectively fixedly connected to one end of the corresponding support shaft.

[0012] By adopting the above technical solution, the drive motor can drive the corresponding support rollers and extrusion rollers to rotate through the support shaft, thereby enabling the extrusion process of the metal sheet.

[0013] Preferably, the guiding component includes a guide groove and a guide plate. The guide groove is symmetrically arranged inside the connecting plate. The guide plate passes through the guide groove, and both ends of the guide plate are fixedly connected to the inner wall of the through groove. A toothed rack is embedded inside the guide plate.

[0014] By adopting the above technical solution, when the connecting plate moves, it will drive the guide groove to slide on the guide plate. The guide groove and the guide plate will cooperate to guide the connecting plate, so that the connecting plate moves smoothly.

[0015] Preferably, the connecting plate has symmetrically arranged frames corresponding to the guide grooves inside, and the frames are connected to the guide grooves. A first gear is rotatably arranged inside the frame, and the first gear meshes with a first rack. A rotating rod is rotatably arranged inside the frame, and a second gear is fixedly installed on the rotating rod, and the second gear meshes with the first gear. A protrusion is fixedly installed on the rotating rod, and a vibration component is arranged inside the frame.

[0016] By adopting the above technical solution, the movement of the connecting plate will drive the frame to move, which in turn will drive the first gear to move. The first gear will rotate through the first rack, and the rotation of the first gear will drive the second gear to rotate, which in turn will drive the rotating rod to rotate, and the rotation of the rotating rod will drive the protrusion to move.

[0017] Preferably, the vibration assembly includes a square groove, a guide plate, a return spring, a sliding block, a guide channel, and a limiting block. The square groove is symmetrically installed inside the frame. The guide plate is fixedly installed inside the square groove. The return spring is arranged around the guide plate, with one end of the return spring fixedly connected to the square groove. The sliding block passes through the square groove. The guide channel is located inside the sliding block, and one end of the guide plate passes through the guide channel. The limiting block is fixedly installed on the sliding block and located inside the square groove. One end of the return spring is fixedly connected to the limiting block.

[0018] By adopting the above technical solution, the rotating rod will drive the protrusion to move. After the protrusion contacts one end of the sliding block, it will push the sliding block to move. At the same time, it will drive the limiting block to slide inside the square groove. The guide groove and the guide plate will make the sliding block move smoothly. When the protrusion and the sliding block are no longer in contact, the reset spring will push the limiting block to reset. The reset limiting block will contact and collide with the square groove, causing the square groove to vibrate. This repeated process will cause the connecting plate to vibrate. The vibration of the connecting plate will drive the extrusion die to vibrate, thereby removing the impurities adsorbed on the extrusion die.

[0019] Preferably, the cleaning component includes an annular groove and air jets. The annular groove is symmetrically mounted on the extrusion die, and the array of air jets is disposed on the annular groove. The inner ring of the extrusion die is symmetrically provided with arc-shaped plates, and the arc-shaped plates are in contact with the extrusion rollers.

[0020] By adopting the above technical solution, after the air enters the annular groove, the air will flow to the outside through the air jet hole. The air comes into contact with the surface of the extrusion roller, which can remove the impurities adsorbed on the surface of the extrusion roller. At the same time, when the position of the extrusion die is adjusted, the arc plate will move, and the movement of the arc plate can remove the impurities adsorbed on the extrusion roller.

[0021] Preferably, the square frame is provided with an air inlet, and the extrusion roller is symmetrically provided with grooves corresponding to the square frame, and the square frame and the grooves are engaged. A second rack is fixedly installed inside the groove.

[0022] By adopting the above technical solution, the movement of the connecting plate will cause the square frame to slide inside the trough, and the cooperation between the trough and the square frame will guide the connecting plate.

[0023] Preferably, the square frame is provided with a support inside, and a No. 3 gear is rotatably arranged inside the support, and the No. 3 gear meshes with the No. 2 rack.

[0024] By adopting the above technical solution, when the square frame moves, the bracket will drive the No. 3 gear to move. When the No. 3 gear moves, the No. 2 rack will rotate the No. 3 gear.

[0025] Preferably, the wind power assembly includes a support ring, a drive rod, a micro fan, an impeller, and a delivery pipe. The support ring is fixedly mounted on a bracket. The drive rod is rotatably disposed inside the support ring. A fourth gear is fixedly mounted on the drive rod, and the fourth gear meshes with a third gear. The micro fan is fixedly mounted inside a square frame. The impeller is disposed inside the micro fan, and one end of the drive rod is fixedly connected to the center of the impeller. One end of the delivery pipe is connected to the output end of the micro fan, and the other end of the delivery pipe is connected to an annular groove.

[0026] By adopting the above technical solution, when the No. 3 gear rotates, the meshing No. 4 gear will drive the drive rod to rotate. When the drive rod rotates, it will drive the impeller to rotate, which will cause the micro fan to work and generate wind. The wind will flow into the annular groove through the delivery pipe, and the wind will flow to the surface of the extrusion roller through the air jet hole, which can remove the impurities adsorbed on the extrusion roller.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. The rolling device for metal sheets described in this invention facilitates the adjustment of the groove position through the connecting plate and the extrusion die. When adjusting the groove position of the metal sheet as needed, the power motor drives the threaded screw to rotate. When the threaded screw rotates, it drives the connecting plate to move through the engagement of the threaded ring, thereby adjusting the position of the extrusion die. This facilitates the groove process at different positions on the metal sheet, improving the flexibility of the metal sheet extrusion device.

[0029] 2. The rolling device for metal sheets described in this invention facilitates the removal of impurities adsorbed on the extrusion rollers through the provided arc-shaped plate and air jet holes. When the extrusion die moves, it drives the arc-shaped plate to move as well. The movement of the arc-shaped plate can remove impurities adsorbed on the extrusion rollers and can also repeatedly adjust the position of the extrusion die to remove impurities adsorbed on the extrusion rollers, thereby improving the cleanliness of the extrusion rollers and effectively preventing impurities adsorbed on the extrusion rollers from affecting the metal sheets, thus improving the flexibility of the metal sheet extrusion device.

[0030] 3. The rolling device for metal sheets described in this invention facilitates the removal of impurities adsorbed on the extrusion die through the square groove and sliding block. When the connecting plate moves, it drives the square frame to slide inside the groove. The groove and the square frame cooperate to guide the connecting plate. When the square frame moves, it drives the third gear to move through the bracket. When the third gear moves, it rotates through the engagement of the second rack. When the third gear rotates, it drives the drive rod to rotate through the meshing fourth gear. When the drive rod rotates, it drives the impeller to rotate, which in turn causes the micro fan to work and generate wind. The wind flows into the annular groove through the conveying pipe and flows to the surface of the extrusion roller through the air jet, which can remove impurities adsorbed on the extrusion roller, improve the cleanliness of the extrusion roller, and effectively prevent impurities adsorbed on the extrusion roller from affecting the quality of extruding the metal sheet.

[0031] 4. The rolling device for metal sheets described in this invention facilitates the collection of cleaned impurities through the provided discharge trough and waste trough. After the cleaned debris falls onto the worktable, it enters the discharge trough and slides into the waste trough for collection. When cleaning the collected debris, the waste trough can be pulled out of the sliding trough, thereby cleaning the debris collected inside the waste trough, achieving the purpose of facilitating the collection of debris and impurities.

[0045] 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.

[0046] like Figures 1 to 11As shown in the embodiment of the present invention, a rolling device for metal sheets includes a worktable 1, a housing 2 fixedly mounted on the worktable 1, a controller 3 mounted on the worktable 1, a support roller 5 disposed inside the worktable 1, an extrusion roller 6 disposed inside the worktable 1, and the extrusion roller 6 being located above the support roller 5. Two sets of annular molds 7 are fixedly mounted on the extrusion roller 6, and extrusion molds 13 are symmetrically mounted around the extrusion roller 6. A through groove 14 is provided inside the extrusion roller 6, a connecting plate 16 is fixedly mounted on the inner ring of the extrusion mold 13, a threaded ring 17 is fixedly mounted inside the connecting plate 16, a threaded screw 18 is rotatably mounted inside the through groove 14, and the threaded screw 18 is threadedly connected to the threaded ring 17. Mounting boxes 19 are symmetrically arranged inside the extrusion roller 6. The mounting box 19 houses a power motor 20, the output of which is fixedly connected to one end of a corresponding threaded screw 18. A battery assembly 21 is installed inside the power motor 20 and electrically connected to it. The extrusion roller 6 has heat dissipation holes 22 connected to the mounting box 19, allowing airflow within the box and improving heat dissipation efficiency. The worktable 1 is equipped with a power assembly for driving the support roller 5 and extrusion roller 6. The worktable 1 also houses a storage assembly. A guide assembly is installed inside the connecting plate 16, and square frames 39 are symmetrically mounted on the connecting plate 16. A wind-powered assembly is installed inside the square frames 39. A cleaning assembly is installed on the extrusion die 13. When using a metal sheet extrusion device to groove the surface of a metal sheet, the power unit drives the extrusion roller 6 and support roller 5 to move. The metal sheet to be processed is manually picked up, and one end of the sheet is inserted between the extrusion roller 6 and support roller 5. The annular die 7 and extrusion die 13 then contact the surface of the metal sheet. Through the cooperation of the extrusion roller 6, the metal sheet is extruded, creating grooves. This enhances the structural strength, rigidity, and aesthetics of the sheet, increases its resistance to bending and torsion, and makes it less prone to deformation under stress. The annular die 7 and extrusion die 13 perform the grooving process on the metal sheet. The power motor 20 is a remote-controlled motor, allowing adjustment of the grooving position on the metal sheet as needed. The operation of the power motor 20 drives the threaded screw 18 to rotate. When the threaded screw 18 rotates, it moves the connecting plate 16 through the engagement of the threaded ring 17. The guide assembly guides the connecting plate 16, ensuring its smooth movement. The movement of the connecting plate 16 allows for adjustment of the position of the extrusion die 13, facilitating groove pressing at different locations on the metal sheet and improving the flexibility of the metal sheet extrusion device. The movement of the connecting plate 16, via the square frame 39, drives the air-powered assembly, generating airflow. This airflow enters the cleaning assembly and removes impurities adsorbed on the extrusion roller 6, effectively preventing impurities on the extrusion roller 6 from affecting the quality of the metal sheet extrusion.Impurities removed from the extrusion roller 6 will fall into the collection assembly for safekeeping, facilitating the collection of debris and impurities.

[0047] like Figure 1 and Figure 3 As shown, the storage assembly includes a discharge trough 8, a sliding trough 9, and a waste trough 10. The sliding trough 9 is located inside the workbench 1, and the waste trough 10 is located inside the sliding trough 9. The discharge trough 8 is located inside the workbench 1 and is connected to the sliding trough 9. An anti-deviation groove 12 is provided on the workbench 1. After the debris falls onto the workbench 1, it enters the discharge trough 8 and slides into the waste trough 10 for collection. When cleaning the collected debris, the waste trough 10 can be pulled out of the sliding trough 9, and the debris collected in the waste trough 10 can be cleaned. After one side of the metal plate to be processed enters the anti-deviation groove 12, the anti-deviation groove 12 can effectively prevent the metal plate from tilting, thus affecting the quality of metal plate processing.

[0048] like Figure 2 , Figure 3 and Figure 10 As shown, the power assembly includes a drive motor 4, which is symmetrically mounted on the worktable 1. Support shafts 15 are fixedly mounted at both ends of the support roller 5 and the extrusion roller 6. A through-tube 11 corresponding to the support shaft 15 is fixedly mounted inside the worktable 1. The support shaft 15 passes through the through-tube 11, and the output ends of the two sets of drive motors 4 are respectively fixedly connected to one end of the corresponding support shaft 15. The support shaft 15 and the through-tube 11 cooperate to support the positions of the connected support roller 5 and extrusion roller 6. The drive motor 4 is electrically connected to the controller 3. The controller 3 can control the operation of the drive motor 4. The operation of the drive motor 4 can drive the corresponding support roller 5 and extrusion roller 6 to rotate through the support shaft 15, thereby performing the extrusion process on the metal plate.

[0049] like Figure 4 and Figure 5 As shown, the guide assembly includes a guide groove 23 and a guide plate 24. The guide groove 23 is symmetrically arranged inside the connecting plate 16. The guide plate 24 passes through the guide groove 23, and both ends of the guide plate 24 are fixedly connected to the inner wall of the through groove 14. A first rack 25 is embedded inside the guide plate 24. When the connecting plate 16 moves, it will drive the guide groove 23 to slide on the guide plate 24. The guide groove 23 and the guide plate 24 cooperate to guide the connecting plate 16, so that the connecting plate 16 moves smoothly. The guide plate 24 provides installation space for the first rack 25.

[0050] like Figure 5 , Figure 6 and Figure 8As shown, the connecting plate 16 has symmetrically arranged frame bodies 26 corresponding to the guide groove 23, and the frame bodies 26 are connected to the guide groove 23. A first gear 27 is rotatably arranged inside the frame body 26, and the first gear 27 meshes with a first rack 25. A rotating rod 28 is rotatably arranged inside the frame body 26, and a second gear 29 is fixedly installed on the rotating rod 28, meshing with the first gear 27. A protrusion 30 is fixedly installed on the rotating rod 28. A vibration component is installed inside the frame body 26. When the connecting plate 16 moves, it will drive the frame body 26 to move, which in turn will drive the first gear 27 to move. The first rack 25 causes the first gear 27 to rotate, which in turn drives the second gear 29 to rotate, which in turn drives the rotating rod 28 to rotate. The rotating rod 28 then drives the protrusion 30 to move, which in turn drives the vibration component to move. The movement of the vibration component, through the connecting plate 16, drives the extrusion die 13 to vibrate, thereby removing impurities adsorbed on the extrusion die 13 and improving its cleanliness. This effectively prevents impurities from adsorbing on the extrusion die 13, which would affect the grooving quality when grooving metal sheets, thus improving the overall processing quality.

[0051] like Figure 6 and Figure 8 As shown, the vibration assembly includes a square groove 31, a guide plate 32, a return spring 33, a sliding block 34, a guide groove 35, and a limiting block 36. The square groove 31 is symmetrically installed inside the frame 26. The guide plate 32 is fixedly installed inside the square groove 31. The return spring 33 is arranged around the guide plate 32, with one end of the return spring 33 fixedly connected to the square groove 31. The sliding block 34 passes through the square groove 31. The guide groove 35 is located inside the sliding block 34, and one end of the guide plate 32 passes through the guide groove 35. The limiting block 36 is fixedly installed on the sliding block 34 and is located inside the square groove 31. One end of the return spring 33 is fixedly connected to the limiting block 36. When the rotating rod 28 rotates, it will drive the protrusion 30 to move. After the moving part contacts one end of the sliding block 34, it will push the sliding block 34 to move. At the same time, it will drive the limiting block 36 to slide inside the square groove 31. The guide groove 35 and the guide plate 32 will make the sliding block 34 move smoothly. When the protrusion 30 no longer contacts the sliding block 34, the reset spring 33 will reset and push the limiting block 36 to reset. The reset limiting block 36 will contact and collide with the square groove 31, causing the square groove 31 to vibrate. This repeated process will cause the connecting plate 16 to vibrate. The vibration of the connecting plate 16 will cause the extrusion die 13 to vibrate, thereby removing the impurities adsorbed on the extrusion die 13, improving the cleanliness of the extrusion die 13, and effectively preventing impurities adsorbed on the extrusion die 13 from affecting the grooving process of the metal plate.

[0052] like Figure 4 and Figure 5As shown, the cleaning assembly includes an annular groove 37 and air jet holes 38. The annular groove 37 is symmetrically mounted on the extrusion die 13, and the air jet holes 38 are arrayed on the annular groove 37. The inner ring of the extrusion die 13 is symmetrically provided with arc-shaped plates 49, and the arc-shaped plates 49 are in contact with the extrusion roller 6. After the generated air enters the interior of the annular groove 37, it will flow to the outside through the air jet holes 38. The air comes into contact with the surface of the extrusion roller 6, which can remove the impurities adsorbed on the surface of the extrusion roller 6. At the same time, when the position of the extrusion die 13 is adjusted, it will drive the arc-shaped plates 49 to move. The movement of the arc-shaped plates 49 can remove the impurities adsorbed on the extrusion roller 6, thereby improving the cleaning purpose of the extrusion roller 6.

[0053] like Figure 4 , Figure 5 and Figure 11 As shown, the square frame 39 is provided with an air inlet 40. The extrusion roller 6 is symmetrically provided with grooves 41 corresponding to the square frame 39, and the square frame 39 and the grooves 41 are engaged. A second rack 42 is fixedly installed inside the groove 41. When the connecting plate 16 moves, it will drive the square frame 39 to slide inside the groove 41. The groove 41 and the square frame 39 cooperate to guide the connecting plate 16. The groove 41 provides installation space for the second rack 42.

[0054] like Figure 9 As shown, a bracket 51 is provided inside the square frame 39. A third gear 50 is rotatably installed inside the bracket 51, and the third gear 50 meshes with the second rack 42. When the square frame 39 moves, the bracket 51 will drive the third gear 50 to move. When the third gear 50 moves, it will rotate through the second rack 42.

[0055] like Figure 9 As shown, the wind power assembly includes a support ring 43, a drive rod 44, a micro fan 45, an impeller 46, and a delivery pipe 47. The support ring 43 is fixedly mounted on the bracket 51. The drive rod 44 is rotatably disposed inside the support ring 43. A fourth gear 48 is fixedly mounted on the drive rod 44, and the fourth gear 48 meshes with a third gear 50. The micro fan 45 is fixedly mounted inside the square frame 39. The impeller 46 is disposed inside the micro fan 45, and one end of the drive rod 44 is fixedly connected to the center of the impeller 46. The delivery pipe 47... The end of the conveying pipe 47 is connected to the output end of the micro fan 45, and the other end of the conveying pipe 47 is connected to the annular groove 37. When the third gear 50 rotates, it will drive the drive rod 44 to rotate through the meshing fourth gear 48. When the drive rod 44 rotates, it will drive the impeller 46 to rotate, which will cause the micro fan 45 to work and generate wind. The wind will flow into the annular groove 37 through the conveying pipe 47. Through the air jet 38, the wind will flow to the surface of the extrusion roller 6, which can remove the impurities adsorbed on the extrusion roller 6 and improve the cleanliness of the extrusion roller 6.

[0056] Working Principle: Firstly, when the metal sheet extrusion device performs groove processing on the surface of the metal sheet, the controller 3 controls the drive motor 4 to operate. The drive motor 4, through the support shaft 15, drives the corresponding support roller 5 and extrusion roller 6 to rotate. The metal sheet to be processed is manually picked up, and one end of the metal sheet is inserted between the extrusion roller 6 and the support roller 5. Then, the annular die 7 and the extrusion die 13 contact the surface of the metal sheet. Through the cooperation of the extrusion roller 6, the metal sheet is extruded, creating grooves on the metal sheet. This enhances the structural strength, rigidity, and aesthetics of the sheet, increases its resistance to bending and torsion, and makes it less prone to deformation under stress. The pressing die 13 can perform a grooving process on the metal sheet. When adjusting the grooving position of the metal sheet as needed, the power motor 20 drives the threaded screw 18 to rotate. When the threaded screw 18 rotates, it drives the connecting plate 16 to move through the engagement of the threaded ring 17. The connecting plate 16 is guided by the guide groove 23 and the guide plate 24, allowing the connecting plate 16 to move smoothly. When the connecting plate 16 moves, the position of the extrusion die 13 can be adjusted, which facilitates the grooving process at different positions on the metal sheet, improving the flexibility of the metal sheet extrusion device. When the extrusion die 13 moves, it also drives the arc plate 49 to move. The movement of the arc-shaped plate 49 can remove impurities adsorbed on the extrusion roller 6 and can also repeatedly adjust the position of the extrusion die 13 to remove impurities adsorbed on the extrusion roller 6, improving the cleanliness of the extrusion roller 6. At the same time, when the connecting plate 16 moves, it will drive the square frame 39 to slide inside the groove 41. The groove 41 and the square frame 39 cooperate to guide the connecting plate 16. When the square frame 39 moves, it will drive the third gear 50 to move through the bracket 51. When the third gear 50 moves, it will rotate through the engagement of the second rack 42. When the third gear 50 rotates, it will drive the drive rod 44 to rotate through the meshing fourth gear 48. When the drive rod 44 rotates, it will drive the impeller 46 to rotate. This will cause the micro fan 45 to work and generate wind. The wind will flow into the annular groove 37 through the conveying pipe 47. Through the air jet 38, the wind will flow to the surface of the extrusion roller 6, which can remove the impurities adsorbed on the extrusion roller 6, improve the cleanliness of the extrusion roller 6, and effectively prevent the impurities adsorbed on the extrusion roller 6 from affecting the quality of extruding the metal sheet. After the removed debris falls onto the worktable 1, the debris enters the discharge chute 8 and slides into the waste chute 10 for collection. When cleaning the collected debris, the waste chute 10 can be pulled out of the sliding groove 9, thereby cleaning the debris collected in the waste chute 10, achieving the purpose of facilitating the collection of debris and impurities.
