Description

Technical Field

[0001] The invention relates to the technical field of aluminum strip coating, and in particular to a device and process for coating aluminum strips. Background Art

[0002] Aluminum strip lamination refers to the process of applying one or more layers of plastic film on the surface of aluminum strip. It is widely used in architectural decoration, electronic products, packaging materials and other fields. This lamination treatment is intended to improve the surface properties of the aluminum strip, such as enhancing corrosion resistance, providing an aesthetic appearance, improving coating adhesion or providing specific functional protection. Usually, the laminated aluminum strip also needs to be precisely cut to obtain the required size and shape.

[0003] The patent application document with publication number CN117227156A provides a coating device for an aluminum coil processing production line, including a machine table, a first reel is installed at the front end of the machine table, an aluminum coil pretreatment mechanism is arranged on the front side of the machine table, and recovery and processing mechanisms are arranged at the positions of the left and right ends of the machine table corresponding to the positions of the aluminum coil pretreatment mechanism, and a coating stabilization mechanism is arranged on the rear side of the machine table. When the aluminum coil moves toward the coating axis, the rectangular plates will separate from each other along the surface of the aluminum coil, so as to clean the stains and dust adsorbed on the surface of the aluminum coil by a cleaning brush, ensure that the film is evenly distributed on the surface of the aluminum coil, and avoid the problem of uneven coating. When the aluminum coil moves and reels on the outer wall of the second reel, the moving block will drive the roller to roll back and forth along the surface of the aluminum coil to both sides, discharge the bubbles between the film and the surface of the aluminum coil, ensure that the film is completely attached to the aluminum coil, thereby improving the stability of the coating, and avoiding the film from loosening and peeling due to bubbles between the film and the aluminum coil during subsequent processing or use.

[0004] However, when the surface of the aluminum coil is cleaned by the movement of the cleaning brush, since the aluminum coil is continuously transported forward, the cleaning brush cannot completely clean the surface of the aluminum coil, and there will be some places that cannot be cleaned, affecting the cleaning effect. In addition, when the bubbles between the film and the surface of the aluminum coil are discharged by the reciprocating rolling of the moving block, the moving block needs to be moved from the middle position of the aluminum coil to both sides of the aluminum coil to discharge the bubbles, so that some bubbles may need to move half the width of the aluminum coil to be discharged outward, resulting in low bubble discharge efficiency, which in turn affects the coating quality and coating efficiency.

[0046] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0047] like Figures 1 to 8 As shown, the aluminum strip slitting and coating device of the present invention includes a frame 1, on which is provided a support platform 11 and a conveying roller 12 for conveying the aluminum strip 6, and also includes a cleaning mechanism, a rolling mechanism, a coating mechanism and a slitting mechanism arranged in sequence along the conveying direction of the aluminum strip 6.

[0048] For ease of understanding, in this embodiment, the length direction of the rack 1 is defined as the front-to-back direction, and the width direction of the rack 1 is defined as the left-to-right direction.

[0049] The cleaning mechanism includes a cleaning roller 21 extending left and right along the axis, and a plurality of cleaning brushes 22 are arranged on the outer side of the cleaning roller 21, and the cleaning brushes 22 extend along the axial direction of the cleaning roller 21. The rolling mechanism includes a rolling roller 31 extending left and right along the axis, and a plurality of rolling wheels 32 installed on the outer side of the rolling roller 31 at intervals along the axial direction of the rolling roller 31, and are used to roll out indentations 61 at positions where the aluminum strip 6 needs to be cut later. The laminating mechanism includes a laminating shaft 41 and an exhaust assembly, and the exhaust assembly includes an exhaust fan and an exhaust roller 42. The air inlet end of the exhaust fan is connected to the aluminum strip through a plurality of suction channels 13. 6 is interconnected, a protruding structure is provided on the outer side of the exhaust roller 42 for scraping the gas between the aluminum strip 6 and the film 7 into the multiple indentations 61 on the aluminum strip 6, the slitting mechanism comprises a slitting roller 51 extending left and right along the axis, and a plurality of slitting knives 52 installed at intervals along the axial direction of the slitting roller 51 on the outer side of the slitting roller 51, the plurality of slitting knives 52 respectively correspond to the plurality of rolling wheels 32 on the outer side of the rolling roller 31, and the frame 1 is provided with a motor 2 34 for driving the rolling roller 31 to rotate, and a motor 3 44 for driving the exhaust roller 42 to rotate.

[0050] Specifically, the aluminum strip 6 is conveyed along the length direction of the frame 1 by the conveying roller 12. During this process, when the aluminum strip 6 is conveyed to the cleaning mechanism, the cleaning brush 22 on the cleaning roller 21 can clean the surface of the aluminum strip 6, and remove the stains and dust adsorbed on the surface of the aluminum strip 6 to ensure the uniformity of the subsequent coating. When the aluminum strip 6 is conveyed to the rolling mechanism, the motor 2 34 is started to drive the rolling roller 31 to rotate. During this process, the rolling wheel 32 on the rolling roller 31 can roll the aluminum strip 6 to roll out a dent 61 at the position where the aluminum strip 6 needs to be cut later. When the aluminum strip 6 is conveyed to the coating mechanism, the film 7 on the coating shaft 41 is attached to the surface of the aluminum strip 6, and then the motor 3 is started. 44 drives the exhaust roller 42 to rotate, so as to scrape the gas between the aluminum strip 6 and the film 7 into the multiple indentations 61 on the aluminum strip 6 through the convex structure on the outer side of the exhaust roller 42, and at the same time, the gas in the indentations 61 is extracted outwardly by the vacuum pump, which can accelerate the discharge of bubbles between the aluminum strip 6 and the film 7. At the same time, in the process of gas discharge, impurities between the aluminum strip 6 and the film 7 can be taken away, so as to clean the surface of the aluminum strip 6 again. When the aluminum strip 6 is transported to the slitting mechanism, the slitting knife 52 on the slitting roller 51 can slit the aluminum strip 6 along the indentations 61 on the aluminum strip 6. Through the setting of the indentations 61, the phenomenon of cutting deviation during the slitting process can be avoided, thereby improving the slitting quality of the aluminum strip 6.

[0051] In some embodiments, a shell 14 is provided on the frame 1, and the cleaning roller 21 and the rolling roller 31 are installed inside the shell 14. There is a gap between the lower end of the shell 14 and the support platform 11 for the aluminum strip 6 to pass through. A plurality of suction channels 13 are arranged on the side of the shell 14 facing the laminating mechanism, and the plurality of suction channels 13 correspond one by one to the plurality of indentations 61 on the aluminum strip 6, respectively. One end of each suction channel 13 faces the corresponding indentation 61, and the other end communicates with the suction port 141 provided on the shell 14.

[0052] Specifically, Figures 2 to 7 As shown, the vacuum pump is connected to the air inlet 141 provided on the shell 14, and after the film 7 is attached to the aluminum strip 6, the motor 44 is started to drive the exhaust roller 42 to rotate, so that the gas between the aluminum strip 6 and the film 7 can be scraped into the indentation 61 on the aluminum strip 6 through the convex structure on the exhaust roller 42. At the same time, the vacuum pump is started, and the gas scraped into the indentation 61 will be sucked into the vacuum pump through the corresponding air inlet channel 13, and then discharged to the outside. Through the cooperation of the indentation 61, the exhaust roller 42 and the vacuum pump, The gas between the aluminum strip 6 and the film 7 is scraped into the multiple indentations 61 by the exhaust roller 42, and can be extracted outwardly through the vacuum pump, so that the gas does not need to pass through the entire aluminum strip 6 and then be discharged outwardly from both sides of the aluminum strip 6, thereby reducing the difficulty of removing bubbles and thus improving the coating efficiency. In addition, through the setting of the shell 14, after the cleaning brush 22 cleans the surface of the aluminum strip 6, the shell 14 can cover the surface of the aluminum strip 6 to prevent impurities from falling on the surface of the aluminum strip 6 again and affecting the subsequent coating effect.

[0053] In some embodiments, a plurality of mounting grooves 211 evenly spaced along the circumference of the cleaning roller 21 are provided on the side wall of the cleaning roller 21, and a cleaning brush 22 is provided in each mounting groove 211. The cleaning brush 22 is slidably matched with the mounting groove 211 and can move radially along the cleaning roller 21. A spring 23 is connected between the end of each cleaning brush 22 facing the mounting groove 211 and the cleaning roller 21, and a motor 24 is provided on the frame 1. The motor 24 is used to drive the cleaning roller 21 to rotate a set angle, so that every time the cleaning roller 21 stops rotating, two adjacent cleaning brushes 22 are in contact with the surface of the aluminum strip 6 at the same time.

[0054] Specifically, Figures 2 to 7As shown, in the set initial state, two adjacent cleaning brushes 22 are in contact with the surface of the aluminum strip 6 at the same time. At this time, as the aluminum strip 6 moves, the two cleaning brushes 22 can successively wipe the same position on the aluminum strip 6. Through two wipes, the cleaning effect of the aluminum strip 6 can be improved. After the cleaning mechanism has been used for a period of time, since the two cleaning brushes 22 are in contact with the aluminum strip 6 successively, the front cleaning brush 22 will adhere to more impurities, while the rear cleaning brush 22 will adhere to less impurities. At this time, the motor 24 is started to drive the cleaning roller 21 to rotate the set angle, and a new cleaning brush 22 is replaced to clean the surface of the aluminum strip 6 In the present embodiment, five cleaning brushes 22 are provided so that the angle between any two adjacent cleaning brushes 22 is 72 degrees. Therefore, when a new cleaning brush 22 needs to be replaced, the cleaning roller 21 is driven by the motor 24 to rotate 72 degrees, and the original cleaning brush 22 at the front is replaced, so that the original cleaning brush 22 at the back is rotated to the front side to continue to clean the surface of the aluminum strip 6. At the same time, the new cleaning brush 22 is rotated to the lower side to contact the surface of the aluminum strip 6. At this time, the surface of the aluminum strip 6 can be preliminarily cleaned by the original cleaning brush 22 at the back, and the surface of the aluminum strip 6 can be cleaned again by the new cleaning brush 22 to ensure the cleaning effect.

[0055] In some embodiments, the rolling mechanism also includes a mounting shell 33 for mounting a rolling roller 31. The mounting shell 33 is mounted inside the shell 14 along the width direction of the frame 1. The rolling roller 31 is rotatably arranged in the mounting shell 33. The lower end of the mounting shell 33 can contact the surface of the aluminum strip 6.

[0056] Specifically, Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, starting motor 2 34 drives the rolling roller 31 to rotate, so that in the process of rolling out the dent 61 on the surface of the aluminum strip 6 through the rolling wheel 32, the lower end of the mounting shell 33 is always in contact with the surface of the aluminum strip 6, which can exert a certain pressing effect on the aluminum strip 6, thereby avoiding the edge warping of the aluminum strip 6 during the rolling process, so as to ensure the quality of the aluminum strip 6.

[0057] In some embodiments, there are multiple raised structures and they are evenly spaced on the outer peripheral side of the exhaust roller 42 along the circumference of the exhaust roller 42. Each raised structure includes a plurality of V-shaped protrusions 43 arranged in sequence along the axial direction of the exhaust roller 42. The tip of each V-shaped protrusion 43 is facing the rotation direction of the exhaust roller 42, and the tip is facing the middle of two adjacent indentations 61 on the aluminum strip 6. The two ends of each V-shaped protrusion 43 are respectively aligned with the two adjacent indentations 61 on the aluminum strip 6.

[0058] Specifically, Figure 1 , Figure 4 and Figure 5As shown, the starting motor 44 drives the exhaust roller 42 to rotate clockwise, and at the same time, it can drive the V-shaped protrusion 43 arranged on the outside of the exhaust roller 42 to rotate synchronously. When the V-shaped protrusion 43 contacts the film 7 attached to the aluminum strip 6, the rotation of the V-shaped protrusion 43 can make the gas between the aluminum strip 6 and the film 7 move from the tip of the V-shaped protrusion 43 along the two oblique sides of the V-shaped protrusion 43 to the two adjacent indentations 61, so that the gas in the aluminum strip 6 and the film 7 can be discharged outward by half of the distance between the two adjacent indentations 61 without moving half of the width of the entire aluminum strip 6, thereby reducing the difficulty of gas discharge and thereby improving the coating efficiency and coating quality.

[0059] In some embodiments, the laminating mechanism also includes two flattening rollers 45 arranged between the shell 14 and the exhaust roller 42, and a hot pressing roller 46 arranged between the exhaust roller 42 and the slitting roller 51. The two flattening rollers 45 are respectively arranged on the upper and lower sides of the aluminum strip 6, and there is a gap between the two flattening rollers 45 for the aluminum strip 6 to pass through. A driving assembly is provided on the frame 1 for realizing the reverse rotation of the exhaust roller 42 and the hot pressing roller 46. The driving assembly includes gears 47 respectively installed on the exhaust roller 42 and the hot pressing roller 46, and the two gears 47 are meshedly connected.

[0060] Specifically, Figures 1 to 4 As shown, after the film 7 is attached to the surface of the aluminum strip 6, the aluminum strip 6 with the film 7 will pass through the gap formed between the two flattening rollers 45 to flatten the film 7 on the aluminum strip 6, which is helpful to achieve the discharge of bubbles and improve the quality of lamination. Then the aluminum strip 6 with the film 7 passes through the exhaust roller 42, and the exhaust roller 42, the vacuum pump and the indentation 61 cooperate to complete the discharge of bubbles. Then the aluminum strip 6 with the film 7 passes through the hot pressing roller 46, and heat and pressure can be applied by the hot pressing roller 46 to activate the adhesive to promote the firm bonding of the film 7 and the aluminum strip 6. By providing a driving component, the hot pressing roller 46 can be driven to rotate in the opposite direction while the exhaust roller 42 is driven to rotate by the starting motor 3 44. The rotation of the hot pressing roller 46 helps to ensure that the film 7 can be evenly heated and pressurized when passing through, which is conducive to achieving good bonding and flatness between the film 7 and the aluminum strip 6, and also helps to discharge bubbles generated during the lamination process, further improving the quality of lamination.

[0061] In some embodiments, a self-cleaning component for cleaning the cleaning brush 22 is also provided in the shell 14, and the self-cleaning component includes a toggle block 25 and an extrusion block 26. The toggle block 25 is provided in plurality and is installed inside the shell 14 along the circumference of the cleaning roller 21, and each toggle block 25 is inclined on the side facing the cleaning roller 21. Two extrusion blocks 26 are provided and are symmetrically installed on the left and right sides of the shell 14. Each extrusion block 26 has an arc surface 1 and an arc surface 2 on the side facing the cleaning roller 21, and the arc surface 1 is set downward, and the arc surface 2 is in contact with the outer wall of the cleaning roller 21. An impurity groove 142 for collecting impurities is provided in the shell 14, and the inlet end of the impurity groove 142 is in contact with the outer wall of the cleaning roller 21. A through hole 261 is provided on the extrusion block 26, and the impurity groove 142 is communicated with the outside through the through hole 261.

[0062] like Figures 1 to 8As shown, when a new cleaning brush 22 needs to be replaced to clean the surface of the aluminum strip 6, the motor 24 is started to drive the cleaning roller 21 to rotate at a set angle, so that the new cleaning brush 22 rotates to the bottom of the cleaning roller 21 to clean the aluminum strip 6. At the same time, the original cleaning brush 22 can be rotated to the top of the cleaning roller 21, and the impurities adhering to the cleaning brush 22 are cleaned by the self-cleaning component. Specifically, the cleaning roller 21 is driven by the motor 24 to rotate clockwise, and the cleaning brush 22 installed on the cleaning roller 21 is driven to rotate synchronously. When the cleaning roller 21 is cleaned, the cleaning brush 22 is rotated to the bottom of the cleaning roller 21 to clean the aluminum strip 6. When the cleaning brush 22 contacts the toggle block 25 provided in the housing 14, the cleaning brush 22 can be moved in the radial direction of the cleaning roller 21 toward the cleaning roller 21 under the action of the inclined surface of the toggle block 25, and the spring 23 is compressed to store force until the cleaning brush 22 passes over the toggle block 25. At this time, the cleaning brush 22 will move in the direction away from the cleaning roller 21 under the action of the spring 23. By retracting and extending the cleaning brush 22, impurities adhering to the cleaning brush 22 can be shaken off, and at the same time, impurities can be removed through the mounting groove 211. The side wall of the cleaning roller 21 scrapes off the impurities adhering to the cleaning brush 22. At this time, the impurities will fall on the outer peripheral side of the cleaning roller 21. As the cleaning roller 21 continues to rotate, the impurities will enter the impurity groove 142 along the inlet end of the impurity groove 142 for collection. During the rotation of the cleaning roller 21, when the cleaning brush 22 contacts the extrusion block 26 installed in the housing 14, the cleaning brush 22 can be moved in the radial direction of the cleaning roller 21 to the direction close to the cleaning roller 21 under the action of the arc surface 1 on the extrusion block 26, and the spring 23 is pressed It retracts and accumulates force until the cleaning brush 22 is completely retracted into the mounting groove 211. At this time, the cleaning roller 21 can smoothly pass over the extrusion block 26 and the impurity groove 142, avoiding the cleaning brush 22 from hindering the rotation of the cleaning roller 21. After the cleaning brush 22 passes over the impurity groove 142, the cleaning brush 22 can be reset under the action of the spring 23. In addition, a through hole 261 is provided on the extrusion block 26, and the air inlet end of the vacuum pump can be connected to the through hole 261, and the vacuum pump can be opened regularly so that the impurities in the impurity groove 142 can be drawn out with the air flow.

[0063] In some embodiments, the frame 1 is further provided with a positioning assembly, which is located between the hot pressing roller 46 and the slitting roller 51, and the structure of the positioning assembly is consistent with the structure of the rolling roller 31. Specifically, the positioning assembly includes a positioning roller 35 whose axis extends left and right, and a plurality of positioning wheels 36 installed at intervals along the axial direction of the positioning roller 35 on the outside of the positioning roller 35. The plurality of rolling wheels 32 correspond to the plurality of positioning wheels 36 one by one, such as Figure 1 and Figure 4 As shown, the rolling wheel 32 rolls out a notch 61 on the aluminum strip 6, and the positioning wheel 36 positions the aluminum strip 6 through the notch 61, which can ensure the linear conveyance of the aluminum strip 6 and avoid the deflection of the aluminum strip 6 during the conveyance process, thereby ensuring the subsequent slitting quality and avoiding the phenomenon of slitting deviation.

[0064] In some embodiments, the frame 1 is also provided with an adjustment component, which includes a cylinder 15 and a screw 16. The cylinder 15 is arranged on the frame 1, and the output end is connected to the shell 14, which is used to drive the shell 14 to move up and down. A moving block 17 is provided on the frame 1 for longitudinal sliding.

The screw 16 is rotatably engaged with the frame 1, and the lower end is threadedly engaged with the moving block 17.

[0065] Specifically, Figure 1 and Figure 2 As shown, the starting cylinder 15 drives the shell 14 to move up and down, and can drive the cleaning roller 21 and the rolling roller 31 installed in the shell 14 to move synchronously. At the same time, rotating the screw 16 can drive the moving block 17 that cooperates with the screw 16 thread to move up and down, and drive the exhaust roller 42 and the hot pressing roller 46 that are rotationally connected to the moving block 17 to move synchronously, so that aluminum strips 6 of different thicknesses can be coated and cut, thereby improving the applicability of the device.

[0066] like Figures 1 to 8 As shown, the present invention also provides a slitting aluminum strip coating process using the above-mentioned slitting aluminum strip coating device, which specifically includes the following steps:

[0067] S1, cleaning: in the process of conveying the aluminum strip 6 along the length direction of the frame 1, when the aluminum strip 6 is conveyed to the cleaning mechanism, the cleaning brush 22 on the cleaning roller 21 can clean the surface of the aluminum strip 6 to ensure the uniformity of subsequent coating;

[0068] S2, rolling: when the aluminum strip 6 is conveyed to the rolling mechanism, the rolling wheel 32 on the rolling roller 31 can roll the aluminum strip 6 to roll out a dent 61 at a position where the aluminum strip 6 needs to be cut later;

[0069] S3, laminating: When the aluminum strip 6 is transported to the laminating mechanism, the film 7 on the laminating shaft 41 is attached to the surface of the aluminum strip 6, and the gas between the aluminum strip 6 and the film 7 is scraped into the multiple indentations 61 on the aluminum strip 6 by the rotation of the exhaust roller 42, and the gas in the indentations 61 is extracted outward by the vacuum pump, so as to accelerate the discharge of bubbles and ensure the laminating efficiency and laminating quality;

[0070] S4. Slitting: When the aluminum strip 6 is transported to the slitting mechanism, the slitting knife 52 on the slitting roller 51 can slit the aluminum strip 6 along the indentation 61 on the aluminum strip 6, avoiding the occurrence of skewed cutting and ensuring the slitting quality.

[0071] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
