Description

Technical Field

[0001] This utility model relates to the technical field of profile surface treatment devices, and in particular to a surface treatment device for aluminum alloy profiles. Background Technology

[0002] Shelving profiles refer to various types of materials used to manufacture shelving shelves, back panels, and beams. Aluminum alloy profiles, with their advantages of light weight and ease of processing, are used to assemble shelving that requires frequent movement, such as display shelves and light-duty storage shelves. To improve the corrosion resistance of shelving products, chromating treatment is usually performed on the surface of aluminum alloy shelving profiles before applying an anti-corrosion coating. This chemical reaction forms a passivation film on the surface of the aluminum alloy profiles, enhancing the corrosion resistance of the surface and the adhesion of the coating, thus improving the corrosion resistance of the shelving products.

[0003] The surface treatment process for aluminum alloy shelving profiles typically includes steps such as degreasing, alkaline washing, water washing, pickling, chromating, and water washing. Therefore, aluminum alloy shelving profiles need to be transferred between multiple tanks. Chinese patent document CN214142548U discloses an alkaline washing device for pre-treatment of aluminum single-panel roller coating, which can realize the transfer of aluminum single-panel inside and outside the alkaline washing tank. However, this alkaline washing device has the following shortcomings: (1) the existing alkaline washing device cannot realize the transfer of aluminum single-panel between multiple tanks; (2) it cannot be used for the transfer of other types of aluminum alloy shelving profiles.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] This utility model provides a surface treatment device for aluminum alloy profiles, aiming to solve the following technical problems:

[0006] (1) Existing alkaline washing equipment cannot transfer aluminum panels between multiple tanks; (2) It cannot transfer other types of aluminum alloy rack profiles.

The railing is provided vertically at multiple intervals, and the railing is located inside the first side frame and the second side frame. The upper and lower ends of the railing are connected to the first side frame or the second side frame.

[0011] Optionally, wire mesh is laid on the inner side of the bottom frame, the inner side of the first side frame, and the inner side of the second side frame.

[0012] Optionally, the triangular lifting rod includes an inverted V-shaped lifting rod body and a structural reinforcing rod for connecting the two sides of the lifting rod body; the structural reinforcing rod is welded to the first side frame, or to the second side frame, or to the railing.

[0013] Optionally, the first support rod is a cylindrical support rod; the lower side of the upper end of the lifting rod body has an arc-shaped groove that cooperates with the cylindrical support rod.

[0018] Beneficial effects:

[0019] This utility model provides a surface treatment device for aluminum alloy profiles. By setting up a crane above multiple pools arranged side by side, and using a cage equipped with triangular lifting rods to load the aluminum alloy profiles, the cage containing the aluminum alloy rack profiles can be transferred into the pools simply by inserting a first support rod through two triangular lifting rods and having the crane lift the first support rod.

[0039] Please see Figures 1 to 8This utility model provides a surface treatment device for aluminum alloy profiles, including multiple pools 1 arranged side by side. It also includes a cage 2, a triangular lifting rod 3, a first support rod 4, a hanging plate 14, and a crane 13.

[0040] Specifically, the cage 2 is used to load processed aluminum alloy shelf profiles; two triangular lifting rods 3 are provided, and the two triangular lifting rods 3 can be fixed to both sides of the cage 2 by welding; the first support rod 4 can be inserted through the two triangular lifting rods 3, and the first support rod 4 is lifted by the crane 13, so that the cage 2 loaded with aluminum alloy shelf profiles can be transferred into the pool 1, and can be transferred between multiple pools 1; the hanging plate 14 can be fixed to the first support rod 4 by welding. By using a crane 13 located above the pool 1 and using the hook of the crane 13 to hold the hanging plate 14, the first support rod 4 and the cage 2 below the first support rod 4 can be lifted. The cage 2 loaded with aluminum alloy rack profiles can be transferred to different pools 1 in sequence according to the surface treatment process. This meets the transfer requirements of aluminum alloy rack profiles between multiple surface treatment processes such as dealkalization, water washing, pickling, chromating, and water washing, ensuring the continuity of the surface treatment process of aluminum alloy rack profiles and improving the efficiency of surface treatment of aluminum alloy rack profiles.

[0041] It should be noted that this utility model does not limit the volume of the pool 1. Each pool 1 can accommodate multiple hanging cages 2, thereby allowing for the surface treatment of a larger number of aluminum alloy rack profiles within the same pool 1. This shortens the processing cycle of the aluminum alloy rack profiles and meets the needs of large-scale production. Furthermore, aluminum alloy rack profiles of different batches or specifications can be flexibly arranged for processing within the same pool 1 according to actual conditions, thus enhancing the flexibility of the profile surface treatment process.

[0042] In this invention, the hanging piece 14 is fixed to the first support rod 4 by welding, forming a strong connection between the hanging piece 14 and the first support rod 4. During the surface treatment of the aluminum alloy rack profile, the cage 2 is frequently lifted and moved by the crane 13; the welding connection method prevents the hanging piece 14 from moving on the first support rod 4, and the first support rod 4 will not separate from the hanging piece 14, thus ensuring the safety of the lifting process.

[0043] like Figure 3 As shown, in an optional embodiment, the cage 2 includes a bottom frame 21, a second support rod 22, a first side frame 23, a second side frame 24, and a railing 25.

[0044] Specifically, the base frame 21 is rectangular; multiple second support rods 22 are horizontally spaced and located within the base frame 21, with both ends of the second support rods 22 connected to two opposite side edges of the base frame 21. In this embodiment, the second support rods 22 provide multiple support points for the aluminum alloy rack profiles, adapting to the placement requirements of profiles of different lengths and shapes, ensuring stable placement of the profiles. Moreover, the second support rods 22 also serve as structural reinforcement, preventing deformation of the base frame 21 when loading profiles, ensuring the overall structural stability of the cage 2, and guaranteeing the safety of the profiles during transfer.

[0045] Specifically, there are two first side frames 23, which are vertically mounted on the two long side frames of the bottom frame 21; there are two second side frames 24, which are vertically mounted on the two short side frames of the bottom frame 21; multiple railings 25 are vertically spaced, and the railings 25 are located inside the first side frames 23 and the second side frames 24, with their upper and lower ends connected to either the first side frame 23 or the second side frame 24. In this embodiment, the first side frames 23, the second side frames 24, and the bottom frame 21 together form the main structure of the cage 2. Combined with the use of the railings 25, this allows the profiles to be stacked to a high height inside the cage 2 without falling off, thus ensuring the safety of the profile transfer process while also increasing the number of profiles that can be surface-treated at one time.

[0046] In an optional embodiment, wire mesh (not shown in the attached drawings) is laid on the inner side of the bottom frame 21, the inner side of the first side frame 23, and the inner side of the second side frame 24. Since smaller aluminum alloy shelving profiles are prone to falling out between the second support rods 22 and the railings 25 after being loaded into the hanging cage 2, the wire mesh laid on the inner sides of the bottom frame 21, the first side frame 23, and the second side frame 24 prevents the smaller aluminum alloy shelving profiles from falling and being damaged or lost. This also ensures safety on the production site and prevents accidents caused by falling profiles. Furthermore, it increases the versatility of the hanging cage 2, allowing it to transfer different types of aluminum alloy shelving profiles.

[0047] like Figure 3 and Figure 4 As shown, in an optional embodiment, the triangular lifting rod 3 includes a lifting rod body 31 in the shape of an inverted V and a structural reinforcing rod 32 for connecting the two sides of the lifting rod body 31; the structural reinforcing rod 32 is welded to the first side frame 23, or welded to the second side frame 24, or welded to the railing 25.

[0048] Specifically, the inverted V-shaped lifting rod body 31 possesses excellent mechanical stability. When bearing the force of the first support rod 4, the lifting rod body 31 can evenly distribute the force to both sides. The addition of the structural reinforcing rod 32 further enhances the structural stability of the triangular lifting rod 3. Furthermore, the structural reinforcing rod 32 can be welded to the first side frame 23, the second side frame 24, and the railing 25, making the triangular lifting rod 3 and the cage 2 form a stable whole. When the crane 13 lifts the cage 2, it can effectively resist external forces generated by swaying and inertia, preventing the cage 2 from tilting or overturning during transfer, thus ensuring the safety of the aluminum alloy rack profile transfer process.

[0049] Furthermore, when the cage 2 is loaded with aluminum alloy rack profiles, it is quite heavy. The connection method of the structural reinforcing rod 32 allows the lifting rod body 31 to bear the weight of the cage 2 and the profiles, so that the triangular lifting rod 3 will not be damaged or broken, further ensuring the safety of the aluminum alloy rack profiles during the transfer process.

[0050] like Figure 3 and Figure 4 As shown, in an optional embodiment, the first support rod 4 is a cylindrical support rod; the upper end of the lifting rod body 31 has an arc-shaped groove 311 that mates with the cylindrical support rod. In this embodiment, the cylindrical support rod and the arc-shaped groove 311 have a large contact area and fit tightly. When the crane 13 lifts the first support rod 4 and moves the cage 2, it can effectively reduce swaying and displacement.

[0051] like Figure 3 and Figure 4 As shown, in an optional embodiment, the cylindrical support rod is provided with two sets of limiting structures; each set of limiting structures includes two limiting posts 41, the axial direction of the limiting posts 41 being perpendicular to the axial direction of the cylindrical support rod; the upper end of the lifting rod body 31 is located between the limiting posts 41, so that when the first support rod 4 lifts the triangular lifting rod 3, the triangular lifting rod 3 will not fall off the first support rod 4, ensuring the safety of the aluminum alloy rack profile during the transfer process.

[0052] like Figure 1 , Figure 2 , Figure 7 as well as Figure 8 As shown, optionally, a drain outlet is provided at the bottom of the pool body 1; a filter screen 5 is provided on the inner wall of the pool body 1 at the drain outlet. The filter screen 5 can be a flat filter screen 5 or a cage filter screen 5, which can initially intercept large-diameter impurities and debris in the treatment liquid of each pool body 1, and can reduce the burden on the recycling device when recycling the treatment liquid of each pool body 1.

[0053] Specifically, the top of the filter screen 5 is detachably connected to two handles 6, both of which are inverted L-shaped, providing convenient leverage points for operators. When cleaning, maintaining, or replacing the filter screen 5, operators can lift it from each pool body 1 by simply gripping the handles 6 without needing additional complicated tools. Furthermore, to facilitate gripping the handles 6, cylindrical grip portions 7 are fitted onto the horizontal portion of the handles 6.

[0054] Specifically, the gripping rod 6 can be fixed to the top surface of each pool body 1 by locking screw 8. This not only allows the filter screen 5 to be covered at the drain port of each pool body 1, but also prevents the filter screen 5 from shifting or shaking under the impact of the flow of the treated liquid in each pool body 1.

[0055] like Figure 5 and Figure 6 As shown, in an optional embodiment, the surface treatment device for the aluminum alloy profile further includes a main water supply pipe 9, a water supply pump 11, a water supply branch pipe 10, and a water filling control valve 12; the output end of the water supply pump 11 is connected to the main water supply pipe 9; the number of water supply branch pipes 10 is the same as the number of pool bodies 1, and the inlet end of the water supply branch pipe 10 is connected to the main water supply pipe, and the outlet end of the water supply branch pipe 10 extends into the interior of the pool body 1; the water filling control valve 12 is installed on the water supply branch pipe 10.

[0056] During the surface treatment of aluminum alloy shelving profiles, the treatment solution in tank 1 may decrease due to evaporation, profile carryover, or the need for solution replacement. Water pump 11 can be connected to the workshop's water storage device or production water source. Through the main water supply pipe 9 and branch water supply pipes 10, pump 11 supplies water to each tank 1, replenishing the consumed treatment solution and maintaining a stable solution level. A stable solution level ensures that the profiles are always completely submerged in the treatment solution (acidic, alkaline, and chromating reagents can be added manually), guaranteeing consistent treatment results and preventing insufficient treatment due to low solution levels, which could affect product quality. Furthermore, by installing a water supply control valve 12 on the branch water supply pipe 10, not only can the amount of water added to tank 1 be controlled, but also the specific tank 1 to which water is supplied.

[0057] like Figure 1As shown, optionally, the pool body 1 includes an alkaline washing pool 101, a water washing pool 102, an acid washing pool 103, a chromating pool 104, and a water washing pool 102 arranged sequentially. The system includes an alkaline washing tank 101 filled with an alkaline aqueous solution to effectively remove oil, grease, and other organic contaminants from the surface of the aluminum alloy shelving profiles. Following the alkaline washing, a water washing tank 102 thoroughly cleans away any residual alkaline solution from the profile surface. An acidic washing tank 103 uses an acidic aqueous solution to remove the natural oxide film on the aluminum alloy profile surface, as well as other impurities generated during processing, such as metal oxides. The chromating treatment in the chromating tank 104 forms a dense passivation film on the aluminum alloy profile surface. This passivation film significantly improves the profile's corrosion resistance and enhances the adhesion of the subsequent anti-corrosion coating to the profile surface, making the shelving products more durable and extending their service life. The water washing tank 102, following the chromating tank 104, removes any residual chromating solution and other reaction products from the chromating process, ensuring a clean and uncontaminated surface and preventing residual substances from adversely affecting the coating quality, thus guaranteeing the surface quality and performance of the final product.

[0058] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
