Description

Technical Field

[0001] The invention relates to the technical field of color-coated plate manufacturing, in particular to a cleaning device for color-coated plate manufacturing. Background Art

[0002] Color-coated sheets are made by coating metal coils with various organic coatings or plastic films. Before coating, the grease on the surface of the color-coated sheets needs to be cleaned.

[0003] During the degreasing process, a degreasing cleaning agent needs to be coated on the surface of the plate, and a spray method is often used to clean the surface of the plate. The traditional spray cleaning method has the following problems: 1. The cleaning agent comes into contact with the plate after spraying, and the cleaning agent is easy to splash, which not only causes a waste of resources, but also easily causes environmental pollution; 2. Spray coating is prone to uneven spraying, which in turn leads to uneven degreasing of the plate surface. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-8 , a cleaning device for color-coated plate manufacturing, comprising a workbench 1, a transport component, a lifting component, a bearing component and a cleaning component, wherein a transport component for transporting materials is arranged at the center above the workbench 1;

[0035] In actual use, the transport assembly includes a driving roller, a driven roller, a motor and a conveyor belt. The conveyor belt is sleeved on the driving roller and a plurality of sets of driven rollers. The motor drives the driving roller to rotate, and the material on the conveyor belt moves accordingly.

[0036] Since it is necessary to perform coating and cleaning operations on plates of different thicknesses, it is necessary to adjust the height of the output end of the cleaning component. The lifting component includes a top plate 2, legs 3, a dual-axis motor 4, a worm gear 5, a worm 6, a protective cover 7 and a threaded rod 8. The four corners below the top plate 2 are arranged on the workbench 1, and the dual-axis motor 4 is also arranged at the center above the top plate 2. The dual-axis motor 4 is symmetrically provided with protective covers 7 on the left and right sides, and the protective cover 7 is provided with a worm gear 5 and a worm 6 that mesh with each other. The output end of the dual-axis motor 4 passes through the corresponding protective cover 7 and is connected to the corresponding worm 6. The threaded rod 8 is arranged in two groups of symmetrical arrangements. The corresponding threaded rod 8 is rotatably connected to the workbench 1 at the bottom, and the corresponding threaded rod 8 passes through the top plate 2 and the protective cover 7 at the top and is connected to the center of the corresponding worm gear 5;

[0037] The cleaning assembly includes a liquid supply tank 9, a liquid supply pump 10, a connecting pipe 11, an output pipe 12, an output head 13, a connecting piece, a coating roller 14 and a roller sleeve 15. The workbench 1 is provided with a liquid supply tank 9 at one end, one end of the liquid supply pump 10 is connected to the liquid supply tank 9, and the other end of the liquid supply pump 10 is connected to the output pipe 12 through the connecting pipe 11. The coating roller 14 is provided with a roller sleeve 15 for contacting the material. The left and right sides of the coating roller 14 are symmetrically provided with connecting pieces connected to the bearing assembly. The output pipe 12 is provided with a plurality of groups of output heads 13 outputting toward the roller sleeve 15.

[0038] The bearing assembly includes a bearing plate 16, a bearing cover 17 and a clutch assembly. There are two sets of symmetrically arranged bearing assemblies on the workbench 1. A bearing cover 17 is arranged on the bearing plate 16. The top wall of the bearing cover 17 is threadedly connected to the threaded rod 8. A connection hole is arranged at one end of the bearing cover 17 close to the coating roller 14. The outer diameter of the connection hole is larger than the outer diameter of the connecting piece. A clutch assembly connected to the connecting piece is also arranged inside the bearing cover 17. A driving motor 19 is also arranged on one set of the bearing plates 16. The output end of the driving motor 19 penetrates through the bearing cover 17 and is connected to the input end of the clutch assembly. A U-shaped bearing frame 18 is also arranged between the two bearing covers 17. The output pipe 12 is embedded in the bearing frame 18. The connecting pipe 11 penetrates through the bearing frame 18 and is connected to the output pipe 12. An output head 13 penetrating through the bearing frame 18 is arranged on the output pipe 12;

[0039] The support legs 3 provide stable support for the top plate 2. The bearing plate 16, the bearing cover 17 and the bearing frame 18 form a lifting plate that is threadedly connected to the two threaded rods 8. Both the dual-axis motor 4 and the driving motor 19 are servo motors with precise control. The dual-axis motor 4 drives the worm 6 to rotate, the worm 6 drives the worm gear 5 to rotate, and the corresponding worm gear 5 drives the threaded rod 8 to rotate. The protective cover 7 ensures the stability of the connection between the worm gear 5 and the worm 6. The lifting plate rises and falls with the rotation of the threaded rod 8. Initially, the lifting plate is at the highest end. At this time, the connecting pieces on both sides of the coating roller are just inserted into the clutch assembly. At this time, it is convenient to disassemble and assemble the coating roller. When the lifting plate is at the lower end, the connecting piece is stably inserted into the clutch assembly at this time. The driving motor 19 drives the clutch assembly to rotate, and the clutch assembly then drives the coating roller to rotate through the connecting piece. The flexible roller sleeve 15 sleeved on the coating roller rotates with the rotation of the coating roller. The liquid supply pump 10 is started. The liquid supply pump 10 sends the cleaning liquid into the connecting pipe 11, and then the liquid is sprayed on the roller sleeve 15 through several output heads 13 of the output pipe 12, and then the roller sleeve 15 contacts the plate to complete the coating operation of the cleaning liquid.

[0040] After long-term operation, impurities are likely to remain on the coating roller sleeved with the roller sleeve 15. Moreover, if the same set of coating rollers and roller sleeves 15 are used for processing different plates, cross-contamination is likely to occur. Therefore, it is necessary to regularly replace the coating rollers sleeved with the roller sleeve 15. If the clutch assembly and the connecting piece adopt a non-spacing adjustable plug-in connection, if the plug-in stroke is too large, it is likely to be inconvenient to disassemble. If the plug-in stroke is too small, when the roller sleeve 15 contacts the material, it is likely to cause the unstable assembly of the coating roller. The clutch assembly includes a rotating shaft 20, a bearing bracket 21, a bearing body 22, a clutch bracket 23, a spline 24, a clutch sleeve 25, a plug block 26, a connecting block 27, a guide bracket 28 and a rack 29. A bearing bracket 21 is arranged above the bearing plate 16. One end of the rotating shaft 20 is connected to the output end of the driving motor 19. The other end of the rotating shaft 20 penetrates through the bearing bracket 21 and is provided with a spline 24. The clutch sleeve 25 is provided with a keyway adapted to the spline 24. The clutch sleeve 25 is slidably connected to the other end of the rotating shaft 20. One end of the clutch sleeve 25 close to the coating roller 14 is provided with a plug block 26 inserted into the connecting piece. A guide rail is arranged on the outer side of the clutch sleeve 25. The clutch bracket 23 is in a U shape with an open top. The inner sides of the two free ends above the clutch bracket 23 are rotatably provided with bearing bodies 22. The bearing bodies 22 are arranged in the guide rail. The outer diameter of the bearing body 22 is the same as the width of the guide rail. The center of the lower part of the clutch bracket 23 is provided with a connecting block 27 connected to the rack 29. A guide bracket 28 slidably connected to the rack 29 is also arranged below the bearing plate 16. A gear 30 with a height higher than the height of the rack 29 is arranged below the threaded rod 8. The rack 29 meshes with the gear 30. A hollow hole for the connecting block 27 and the gear 30 to move is also arranged below the bearing plate 16. When the lifting plate is in a higher state, that is, the gear 30 is flush with the upper surface of the rack 29. At this time, the rack 29 is located away from the coating roller. At this time, the clutch assembly and the connecting piece are just clamped. When coating operation is required, the lifting plate needs to descend. At this time, the threaded rod 8 drives the gear 30 to rotate. A guide bracket 28 slidably connected to the rack 29 is arranged below the bearing plate 16. The rack 29 descends relative to the gear 30 along with the bearing plate 16. The gear 30 drives the rack 29 to move towards the coating roller. The rack 29 drives the clutch bracket 23 to move towards the coating roller through the connecting block 27. The clutch bracket 23 is provided with a bearing body 22 contacting the guide rail of the clutch sleeve 25. The clutch sleeve 25 moves towards the connecting piece on the rotating shaft 20 under the guidance of the spline 24, further completing the insertion of the plug block 26 of the clutch sleeve 25 into the connecting piece, ensuring the stability of the coating roller sleeved with the roller sleeve 15 during operation. The driving motor 19 drives the rotating shaft 20 on the bearing bracket 21 to rotate. The rotating shaft 20 drives the clutch sleeve 25 to rotate through the spline 24. The clutch sleeve 25 further drives the coating roller with the connecting piece to rotate.

[0041] In this embodiment, the connecting member includes a support tube 31, an elastic member and a connecting seat 32. The coating roller 14 is symmetrically provided with support tubes 31 on both sides. The two ends of the elastic member are respectively connected to the inner wall of the support tube 31 and one end of the connecting seat 32. The other end of the connecting seat 32 is provided with a slot adapted to the plug block 26. The elastic member includes a telescopic rod 33 and a spring 34. The spring 34 is sleeved on the telescopic rod 33. The two ends of the spring 34 and the telescopic rod 33 are respectively connected to the inner wall of the support tube 31. It is connected to a connecting seat 32, and the outer diameter of the connecting seat 32 is consistent with the outer diameter of the clutch sleeve 25. Initially, when the lifting plate is at a higher end, the distance between the output end of the clutch assembly and the connecting piece is larger, and the elastic piece is in a naturally extended state. The elastic piece is squeezed by the connecting seat 32 to align the slot of the connecting seat 32 with the plug block 26, and then the connecting seat 32 is released. At this time, the spring 34 pushes the connecting seat 32 to reset, and the telescopic rod 33 ensures the stability of the movement of the connecting seat 32. The support tube 31 provides stable support for the elastic piece and the connecting seat 32.

[0042] In actual use, the above structure has the problem of inconvenience in aligning the slot and the plug block 26. The bearing cover 17 is also provided with a closing inclined plate 35 for auxiliary guiding of the connecting member near one end of the connecting member. The closing inclined plate 35 is arranged on the front and rear sides of the corresponding connecting member. The bearing plate 16 is provided with a support member for supporting the support tube 31. The support member includes an auxiliary roller 36 and an auxiliary frame 37. The auxiliary frame 37 is fixed on the bearing plate 16. The auxiliary rollers 36 supporting the support tube 31 are symmetrically arranged at the front and rear ends of the auxiliary frame 37. A limiting ring 39 is also provided on the support ring. The limiting ring 39 is symmetrically arranged on both sides of the corresponding two groups of the auxiliary rollers 36. The outer side of the connecting seat 32 is also symmetrically provided with a guide block 38. The guide block 38 is arranged on the upper and lower sides of the slot. The connecting hole A positioning groove adapted to the guide block 38 is also provided on the top, and the inner diameter of the connecting hole is larger than the maximum spacing between the two groups of guide blocks 38. An unlocking ring 40 is also provided on the connecting seat 32, and the unlocking ring 40 is arranged between the bearing cover 17 and the coating roller 14. The closing inclined plate 35 is convenient for pre-positioning the connecting piece, and the guide block 38 is inserted downwardly into the positioning groove, and the connecting seat 32 is conveniently driven to extrude the elastic member through the unlocking ring 40. The front and rear auxiliary rollers 36 are located between the corresponding two groups of limit rings 39. After the auxiliary rollers 36 support the support tube 31, the unlocking ring 40 is released, and the elastic member drives the connecting seat 32 to plug into the plug block 26. When the lifting plate is in a lower position, due to the feeding of the clutch sleeve 25 with the plug block 26, the distance of the plug block 26 inserted into the slot becomes deeper. At this time, the coating roller is stably assembled, not easy to fall off, and easy to use.

[0043] In this embodiment, the output head 13 is provided with an electromagnetic switch valve 41, and the electromagnetic switch valve 41 is arranged on the outside of the support frame 18. The electromagnetic switch valve 41 is used to conveniently control the output of the corresponding output head 13. The support cover 17 is also embedded with an observation window 42, through which the connection status of the clutch assembly and the connecting part can be conveniently understood.
