Description

Technical Field

[0001] This utility model relates to the field of color-coated steel sheet coating technology, and more specifically, to coating equipment for color-coated steel sheets with self-cleaning function. Background Technology

[0002] The coating equipment for self-cleaning functional color-coated plates is a professional system that integrates advanced technologies such as nanomaterial processing, precision coating and functional curing. Its core lies in achieving uniform dispersion and stable coating of nano-functional materials.

[0003] Typically, self-cleaning pre-coated steel sheets require an additional self-cleaning coating layer on top of the standard pre-coated sheet. Since traditional pre-coated steel sheet coating equipment is only capable of single-coat application, the standard pre-coating process must be completed first, followed by a second coating in specialized equipment to add the self-cleaning coating. This process doubles energy consumption, labor costs, and production efficiency. Therefore, developing equipment capable of completing the self-cleaning pre-coated steel sheet coating process in a single step is crucial. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a device for completing the self-cleaning color-coated steel sheet coating in one step, so as to solve the problems in the background technology.

Each air inlet chamber has two sets of evenly distributed air outlet holes on its inner wall.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0026] Please see Figure 1-4 In this utility model: a coating equipment for color-coated steel sheets with self-cleaning function includes a workbench 1, on which two feed troughs 2 and two paint troughs 3 are provided. Two symmetrically arranged coating mechanisms 4 are installed on the inner wall of the workbench 1. A cavity 5 is provided inside the workbench 1, and an air inlet pipe 6 is connected to the inner wall of the cavity 5. An air pump 7 is installed on the air inlet pipe 6. Four electric heating plates 8 are installed on the inner wall of the cavity 5. Two air outlet pipes 9 are connected to the inner wall of the cavity 5. One end of each of the two air outlet pipes 9 is fixedly connected to a drying chamber 10. Each of the two drying chambers 10 has a conveying trough 11 and an air inlet chamber 12. The chambers 12 are all annular in shape. The inner walls of the two air inlet chambers 12 are connected to the two air outlet pipes 9 respectively. The inner walls of the two air inlet chambers 12 are provided with two sets of evenly distributed air outlet holes 13. The coating mechanism 4 includes a material conveying roller 401, a coating roller 402 and a steering roller 403. The two ends of the material conveying roller 401, the coating roller 402 and the steering roller 403 are rotatably connected to the inner wall of the worktable 1. The material conveying roller 401 is located inside the paint tank 3. Three motors 404 are fixedly connected to the back of the worktable 1. The output shafts of the three motors 404 are fixedly connected to the material conveying roller 401, the coating roller 402 and the steering roller 403 respectively.

[0027] In this invention, the pre-treated color-coated steel plate substrate enters from the left feed chute 2. The plate is redirected by the left steering roller 403, moving to the right. It then passes the right steering roller 403 again and exits from the right feed chute 2. The two paint tanks 3 contain paint and self-cleaning paint, respectively. At the start of coating, six motors 404 are simultaneously activated, driving the conveyor roller 401, coating roller 402, and steering roller 403. First, the left conveyor roller 401 rotates, transferring the paint from the left paint tank 3 to the coating roller 402, forming a wet film of a certain thickness on its surface. The coating roller 402 then transfers this wet film to the surface of the color-coated steel plate substrate, achieving a one-time coating effect. The coated plate then enters the conveyor chute 11 in the top drying chamber 10. Before this, the air pump 7 is activated to input air into the cavity 5, which is then heated by the heating plate 8. Air enters the air inlet chamber 12 through the air outlet pipe 9. The heated air is then sprayed out through the air outlet 13 and blown evenly onto the color-coated sheet. After the hot air blows onto the color-coated sheet, it achieves a pre-drying treatment of the color-coated sheet after the first coating. After the color-coated sheet is dried, it passes through the right-side turning roller 403. The rotation of the right-side conveying roller 401 transfers the self-cleaning coating in the right-side coating tank 3 to the coating roller 402, forming a wet film of a certain thickness on the surface of the coating roller 402. Then, the coating roller 402 transfers the wet film to the surface of the color-coated sheet, thereby achieving the effect of secondary coating of the color-coated sheet and completing the purpose of coating the color-coated sheet with self-cleaning coating. The color-coated sheet that has completed the secondary coating enters the conveying trough 11 in the bottom drying box 10. The hot air in the cavity 5 can also enter the air inlet chamber 12 in the bottom drying box 10 through the air outlet pipe 9 on the right side. The hot air is blown onto the color-coated sheet that has undergone secondary coating through the air outlet 13, thereby achieving the effect of drying the self-cleaning coating on the color-coated sheet.

[0028] Please see Figure 2 The air intake pipe 6 has an air intake cover 14 fixedly connected to one end of its back side, and a filter screen 15 is fixedly connected to the inner wall of the air intake cover 14.

[0029] In this invention, the air intake hood 14 can be used to install the filter screen 15, which can filter the air and prevent dust from entering the cavity 5 and blowing onto the color-coated plate, thereby improving the quality of the color-coated plate coating.

[0030] Please see Figure 1 Among them, the front of the workbench 1 is fixedly connected to a controller 16 that controls the opening and closing of the air pump 7, the electric heating plate 8, and the motor 404.

[0031] In this invention, the controller 16 facilitates the user's control of the air pump 7, the heating plate 8, and the motor 404, thereby improving the practicality of the device.

[0032] Please see Figure 3 Among them, a solenoid valve 17 is installed on the air outlet pipe 9, and the output terminal of the controller 16 is connected to the solenoid valve 17 for signal transmission.

[0033] In this invention, the solenoid valve 17 can be configured to control the hot air outflow path. When only one coat of paint is needed for the color-coated sheet, the solenoid valve 17 on the bottom air outlet pipe 9 can be closed. At this time, the hot air will only flow out from the top drying box 10 and the bottom drying box 10 will be closed. This saves energy and avoids damage to the color-coated sheet during secondary drying, thereby improving the practicality of the device.

[0034] Please see Figure 2-4 The workbench 1 has two air ducts 18 fixedly connected to its back side. The inner sides of the two air ducts 18 are in contact with the two drying boxes 10 respectively. The two air ducts 18 are U-shaped. The back side of the two air ducts 18 is connected to the exhaust pipe 19. The two exhaust pipes 19 are equipped with air pumps 20. The back side of the two air ducts 18 has two filter plates 21 and two activated carbon layers 22.

[0035] In this invention, during the drying process, there are certain harmful substances in the hot air. By turning on the air pump 20, the air in the drying area is drawn into the back of the workbench 1 through the air duct 18 via the air extraction pipe 19. The air is then filtered and adsorbed by the filter plate 21 and the activated carbon layer 22 in sequence, thereby effectively preventing harmful gases from harming the health of workers and improving the safety of the device.

[0036] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
