[0001] This utility model relates to the field of aluminum plate production, and in particular to a thin aluminum plate cleaning device for aluminum plate production. Background Technology

[0002] In the aluminum sheet production industry, the cleaning of thin aluminum sheets is crucial. During manufacturing, transportation, and subsequent processing, the surface of aluminum sheets is highly susceptible to the adhesion of oil, dust, aluminum powder, and other contaminants. If these contaminants are not effectively removed, they will seriously affect the surface quality of the aluminum sheets, negatively impacting subsequent coating, printing, and bonding processes. This can lead to problems such as reduced coating adhesion, blurred printed patterns, and weak bonding, ultimately reducing the overall quality and market competitiveness of the product.

[0003] Currently, some cleaning devices on the market use water cleaning, which uses the impact of water flow and cleaning agents to remove dirt from the surface of aluminum plates. It has the advantages of low cost and simple operation, and is suitable for large-scale production lines.

[0004] Existing thin aluminum plate cleaning devices have certain limitations in structural design and functional implementation. For example, some devices have a relatively simple scraper configuration, which cannot effectively clean different types of contaminants in stages. In terms of maintenance and upkeep, the disassembly and replacement of some internal components are inconvenient, increasing maintenance costs and downtime, and affecting production efficiency. Therefore, a thin aluminum plate cleaning device for aluminum plate production is proposed to solve the above problems. Utility Model Content

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by setting up an upper scraper, a connecting plate, a shell, a lower scraper, a slot, and a limiting component, the upper scraper is made of three different materials, which are used to remove burrs, dust and dirt, and residual water stains respectively.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a thin aluminum plate cleaning device for aluminum plate production, comprising a shell 1, with protective covers 2 at both the front and rear tops of the shell 1. The protective covers 2 are used to open the middle of the shell 1 for easy replacement of the upper scraper 12 and the lower scraper 18. They can be made of transparent acrylic material for easy external viewing of the cleaning process. Frame plates 3 are fixedly connected to the outer walls on both sides of the shell 1. The two sets of frame plates 3 serve as the inlet and outlet of the aluminum plate, facilitating direct alignment with the cleaning position. A placement plate 4 is fixedly connected to the middle of the outer wall of the frame plate 3. The placement plate 4 can be used to provide an auxiliary support position for lifting the aluminum plate, or to stack the aluminum plate, which is pushed into the device by a feeding device. A water pipe 5 is penetrating and fixedly connected to the inner wall of the right back of the shell 1. The outer end of the water pipe 5 is connected to a water pump for transmitting water to spray onto the surface of the aluminum plate through nozzles 6 to achieve a rinsing effect. Nozzles 6 are provided on the outer arc surface of the water pipe 5. Several sets of nozzles 6 are arranged vertically for multi-point spraying. The water source is used to rinse the aluminum plate. A drain hole 7 is provided at the bottom of the inner wall of the outer shell 1. There are three sets of drain holes 7, two in a group, located in the rinsing area, cleaning area and air drying area respectively, to drain the water from the outer shell 1. A water storage tank or diversion tank needs to be set at the bottom to collect the water after cleaning. A transmission roller 8 is set in the middle of the inner wall of the outer shell 1. The transmission roller 8 is existing technology and will not be described in detail. There are two sets of transmission rollers 8, which are used to transfer the aluminum plate to move laterally. A cylinder 9 is fixedly connected to the top of the outer shell 1. The cylinder 9 is existing technology and will not be described in detail. It is used to drive the connecting plate 10 to move up and down, thereby driving the upper scraper 12 and the auxiliary roller 11 to move up and down as well, so as to achieve the effect of cleaning aluminum plates of different thicknesses. The output end of the cylinder 9 is fixedly connected to the connecting plate 10. The connecting plate 10 is used to support the auxiliary roller 11 and is clamped to the upper scraper 12 by the limiting component to provide it with suspension support. The outer wall of the bottom end of the connecting plate 10 is slidably connected to the inner wall of the outer shell 1.

[0035] Reference Figures 3-5An auxiliary roller 11 is rotatably connected to the inner side of the bottom end of the connecting plate 10. The auxiliary roller 11 is used to maintain the stable lateral movement of the aluminum plate and prevent it from being pressed or naturally touching the lower scraper 18, which would cause the aluminum plate to get stuck. The bottom of the connecting plate 10 is connected to the upper scraper 12 through a limiting component. The upper scraper 12 is provided with three sets, which can be set with three different materials. The first set on the right can be set with a hard material to remove burrs or flash during the production process. The second set can be set with a fine brush or cotton cloth to remove dust and dirt from the surface. The third set is set with a soft rubber material to remove residual water. A slot 13 is opened on the side of the upper scraper 12 away from the auxiliary roller 11. The slot 13 is used to engage the limiting component and fix the upper scraper 12 to the inner wall of the connecting plate 10. The bottom of the inner wall of the outer shell 1 is engaged with the lower scraper 18 through the limiting component. The lower scraper 18 is set with a material corresponding to the upper scraper 12 to achieve a bidirectional cleaning effect. The upper scraper 12 is engaged with the bottom inner wall of the connecting plate 10.

[0036] Reference Figures 1-3 The inner wall of the outer casing 1 has a U-shaped groove 19, which is used to connect four sets of air outlets 20 to reduce the energy consumption of multiple fans and compress the air source so that it can only be blown out through the air outlets 20. The top and bottom of the inner wall of the outer casing 1 at the U-shaped groove 19 are fixedly connected to the air outlets 20. The air outlets 20 are provided with an upwardly inclined scraper 12 and a downward scraper 18. The front and rear sets are set to prevent water from being blown towards the auxiliary roller 11 and then rebounding. Multiple air blowing can achieve the effect of air drying. The top of the outer casing 1 is connected to the U-shaped groove 19 through and fixedly connected to the air duct 21. The air duct 21 needs to be connected to an external fan to transmit the air source into the U-shaped groove 19 and then to the air outlets 20 through the U-shaped groove 19. There are four sets of air outlets 20, one above the other. The air outlet end is set to be angled and aligned with the middle of the inner wall of the outer casing 1. The top and bottom ends of the U-shaped groove 19 are interconnected with the air outlets 20.

[0037] Reference Figures 4-6The limiting assembly includes a limiting rod 15, which is used to simultaneously release the limiting block 16, facilitating manual release. The limiting rod 15 is slidably connected to the inner wall of the connecting plate 10. A connecting rod 17 is elastically connected to the inner wall of the connecting plate 10 via a limiting spring 14. The connecting rod 17 is used to connect to the limiting block 16, simultaneously releasing the limiting of the two sets of upper scrapers 12 on the right side via the limiting rod 15. The limiting block 16 is fixedly connected to the bottom left side of the connecting rod 17. The limiting block 16 is used to engage with the slot 13, so that both ends of the upper scraper 12 are stably engaged on the inner wall of the connecting plate 10. One end of the limiting spring 14 is fixed. The other end of the limiting spring 14 is fixedly connected to the inner wall of the connecting plate 10. Through the opposing pressing force between the limiting spring 14 and the connecting plate 10, the limiting block 16 and the limiting rod 15 are always locked on the inner wall of the slot 13 without being affected by external force. The top of the limiting rod 15 is fixedly connected to the bottom right side of the connecting rod 17. The connecting rod 17 is slidably connected to the inner wall of the connecting plate 10. The left side of the limiting rod 15 is inserted into the inner wall of the slot 13. The limiting block 16 is slidably connected to the inner wall of the connecting plate 10 and locked on the inner wall of the slot 13.

[0038] Working principle: During the aluminum plate feeding stage, the aluminum plate is pushed to the placement plate 4 of the frame plate 3 by the feeding device. The placement plate 4 can provide a leverage point for manual feeding and can also temporarily store the aluminum plate. Then, the aluminum plate enters the device through the feed port of the frame plate 3 and is driven by the transmission roller 8 to move the aluminum plate laterally, thus starting the cleaning process.

[0039] In the cleaning process, the water pump transmits water to the nozzles 6 through the water pipes 5. The nozzles 6 have multiple sets of structures distributed vertically to spray water from multiple points, performing a preliminary rinse on the aluminum plate surface to remove most of the stains and impurities. The wastewater after rinsing is discharged through the drainage holes 7 at the bottom of the inner wall of the outer shell 1. The drainage holes 7 are set in different areas to ensure that wastewater from each stage is discharged in a timely manner, avoiding water accumulation that could affect the cleaning effect.

[0040] When the aluminum plate moves to the scraper cleaning area, the cylinder 9 drives the connecting plate 10 to move up and down, which in turn drives the auxiliary roller 11 and the upper scraper 12 to adjust their positions to accommodate aluminum plates of different thicknesses. The auxiliary roller 11 keeps the aluminum plate moving horizontally and prevents it from getting stuck due to pressure or natural drooping and touching the lower scraper 18. The upper scraper 12 has three sets of different material structures: a hard material scraper to remove burrs, a brush or cotton cloth scraper to remove dust and dirt, and a soft rubber scraper to remove residual water. These structures work in conjunction with the lower scraper 18 to achieve all-round bidirectional cleaning of the aluminum plate surface.

[0041] After cleaning, the aluminum plate continues to move forward and enters the drying area. An external fan transmits air through the air duct 21 to the U-shaped groove 19. The U-shaped groove 19 connects to four sets of air outlets 20. After compressing the air source, the air is blown out from the inclined air outlets 20. The four sets of air outlets 20 are obliquely aligned with the aluminum plate. Multiple air blows dry the residual moisture on the surface of the aluminum plate. The setting of the front and rear sets of air outlets 20 prevents water from flowing back to the auxiliary roller 11, ensuring the drying effect.

[0042] In terms of device maintenance, when it is necessary to replace the upper scraper 12 and the lower scraper 18, open the protective cover 2, manually pull the limit rod 15, the limit rod 15 drives the limit block 16 to move outward against the elastic force of the limit spring 14 through the connecting rod 17, release the locking of the slot 13, and then the scraper can be disassembled for replacement. The operation is convenient and quick.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
