Technical Field

[0001] This utility model relates to the field of pressed steel plate processing technology, and in particular to a surface spraying device for pressed steel plate processing. Background Technology

[0002] Pressed steel sheet is a type of steel sheet with an organic coating. It has advantages such as good corrosion resistance, bright colors, beautiful appearance, convenient processing and forming, and the original strength of steel sheet, as well as low cost.

[0037] The dust and impurity wiping mechanism is installed on the top of the L-shaped support base 1 and the top inner wall of the U-shaped support plate 3. The dust and impurity wiping mechanism includes two wiping cottons 701. The wiping cottons 701 are used to wipe and clean the dust and impurities on the pressed steel plate. The top inner wall of the U-shaped support plate 3 and the top of the L-shaped support base 1 are both fixedly connected to the connecting base 7.

The side of the two wiping cottons 701 that are close to each other is flush with the top of the first roller 401 and the bottom of the second roller 402.

[0038] The dust and impurity extraction and collection mechanism 8 includes a third loop tube 801 fixedly installed on the top of the L-shaped support 1. Multiple inclined suction heads 802 are fixedly connected to the top and bottom of the inner side of the third loop tube 801. The suction heads 802 are inclined towards the wiping cotton 701 and can be used to extract dust and impurities adhering to the wiping cotton 701, maintaining its cleanliness and not affecting subsequent cleaning work. A filter box 803 is fixedly connected to the top of the third loop tube 801, and a connecting pipe is fixedly connected to the bottom of the filter box 803. The bottom end of the connecting pipe extends into the third loop tube 801. A filter screen 805 is movably fitted inside the filter box 803, used to filter, block, and collect the extracted dust. A plug is fixedly connected to the front of filter screen 805 and movably fitted inside filter box 803. A U-shaped handle is fixedly connected to the front of the plug, allowing filter screen 805 to be removed for cleaning of filtered dust. An air pump 804 is fixedly connected to the top of filter box 803, with its extraction end extending into filter box 803 for suction. This invention, through a series of structural designs, can wipe and suction clean the dust on the top and bottom of the pressed steel plate during its movement before spraying, eliminating the need for separate personnel. It can also dry the pressed steel plate after spraying, eliminating the need for separate subsequent drying operations. This integrated design of wiping, cleaning, spraying, and drying achieves multi-functionality, effectively improving work efficiency.

[0039] Working principle: In use, the left side of the steel plate to be coated is placed between the first roller 401 and the second roller 402 on the right side, with the bottom of the steel plate in contact with the top of the first roller 401. Then, the four electric telescopic rods 2 are opened synchronously via a synchronous control switch. The output shafts of the four electric telescopic rods 2 simultaneously drive the U-shaped support plate 3 downwards. The U-shaped support plate 3 drives the two second rollers 402 downwards until they are in contact with the top of the steel plate, at which point the four rollers are closed. The electric telescopic rod 2 is activated simultaneously with two drive motors 403, an air pump 804, an extraction pump 602, and a hot air blower 503. The drive motor 403 drives the corresponding second rotating roller 402 to rotate. As the second rotating roller 402 on the right rotates, it works in conjunction with the first rotating roller 401 on the right to rub and drive the pressing steel plate to move to the left. The pressing steel plate passes through the third loop tube 801, two wiping cottons 701, the second loop tube 601, the first loop tube 501, and between the first rotating roller 401 and the second rotating roller 402 on the left in sequence.

[0040] As the pressed steel plate passes between the two wiping cottons 701, the two wiping cottons 701 rub against the top and bottom of the pressed steel plate respectively. Under the friction, the dust and impurities adhering to the top and bottom of the pressed steel plate can be rubbed away. At the same time, the air pump 804 sequentially sucks away the rubbed dust and the dust on the pressed steel plate through the filter box 803, the connecting pipe, the third loop pipe 801 and multiple suction pipe heads 802. It can also suck away the dust adhering to the wiping cottons 701. Under the suction force, the gas containing dust enters the filter box 803 and is discharged to the outside by the air pump 804. At the same time, the filter screen 805 filters and blocks the dust at its bottom, thereby achieving the purpose of wiping and sucking away the dust and impurities on the pressed steel plate before spraying. By wiping and cleaning during the automatic movement of the pressed steel plate, there is no need for personnel to clean it separately before spraying, thereby improving work efficiency.

[0041] When the cleaned pressed steel plate enters the second loop 601, the extraction pump 602 draws the paint from the paint tank 603 through the L-shaped suction pipe 605 and pumps it into the second loop 601. The paint inside the second loop 601 is sprayed out through multiple spray atomizing nozzles 604 to spray the top and bottom of the pressed steel plate. When the sprayed pressed steel plate enters the first loop 501, the hot air fan 503 draws in the external air and discharges hot air into the first loop 501. Inside the loop tube 501, hot air from inside the first loop tube 501 is discharged through multiple air blowing heads 502 to dry the coated and pressed steel plate. The dried pressed steel plate is removed by the first rotating roller 401 and the second rotating roller 402 on the left side. By directly blowing hot air to dry the pressed steel plate during the removal process after coating, no separate drying operation is required afterward. The integrated design of wiping, cleaning, spraying and drying achieves a multi-functional effect and can effectively improve work efficiency.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
