[0027] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0028] like Figure 1 This is a schematic diagram of the structure of the utility model, a high-quality hot-dip aluminum-zinc plate coating machine, including:

[0029] Frame 1 is used for equipment installation. Frame 1 also has a dryer that can dry the coated steel plates.

[0030] The transmission mechanism 2 is used to transport the aluminum-zinc plate. The transmission mechanism 2 is installed on the frame 1. The transmission mechanism 2 can be a chain conveyor or a belt conveyor.

[0031] The coating mechanism 3 is used to apply coating to the aluminum-zinc sheet. The coating mechanism 3 includes a coating roller 31, which is rotatably connected to the frame 1. The coating mechanism 3 includes a coating seat 32 and a slide rail 33. The slide rail 33 is fixedly connected to the frame 1, and the coating seat 32 is slidably connected to the slide rail 33. The coating roller 31 is rotatably connected to the coating seat 32, so that the coating roller 31 can be moved, which is convenient for replacement and maintenance. The coating mechanism 3 is located above the transmission mechanism 2.

[0032] like Figure 2 、 Figure 3 、 Figure 6As shown, the scraping mechanism 4 is used to scrape off excess paint on the paint roller 31. The scraping mechanism 4 includes an adjusting component 41 and a scraping plate 42. The adjusting component 41 is fixedly connected to the frame 1. The output end of the adjusting component 41 is transmission-connected to the scraping plate 42. The adjusting component 41 is used to provide power for the scraping plate 42 to move away from or approach the paint roller 31. The scraping plate 42 includes a connecting section 421, a material receiving portion 422 and a scraping head 423. One end of the connecting section 421 is transmission-connected to the adjusting end of the adjusting component 41, and the other end is fixedly connected to the material receiving portion 422. The material receiving portion 422 is fixedly connected to the scraping head 423. The material receiving portion 422 is used to receive the scraped paint. The material portion 422 is located between the scraper head 423 and the connecting section 421. Through the design of the material receiving portion 422 on the scraper plate 42, the scraped paint can be accommodated to prevent it from accumulating between the scraper plate 42 and the paint roller 31. The material receiving portion 422 has a V-shaped structure, and the inner bottom surface of the material receiving portion 422 has an inclined guide surface 424. The guide surface 424 is an arc-shaped surface. The scraped paint can be guided out through the guide surface 424 to avoid excessive accumulation of paint in the material receiving portion 422. The present application can add a collection frame to the frame 1. The collection frame is used to collect the paint flowing out from the end of the material receiving portion 422 to avoid the need to stop the machine to observe and clean the material receiving portion 422 during use.

[0033] like Figure 3 、 Figure 4 、 Figure 5 As shown, the material receiving portion 422 extends to the outside of the frame 1, and a through hole 11 is provided on the frame 1 for the material receiving portion 422 to move. The material receiving portion 422 passes through the through hole 11, and the guide surface 424 gradually lowers toward the through hole 11, so that excess paint can be discharged.

[0034] The scraping head 423 is located in the fourth quadrant, the origin of which is the center of the paint roller. This application establishes a coordinate system based on the center of the paint roller, and the scraping head 423 is facing the rotation direction of the paint roller 31. By arranging the scraping head 423 in the fourth quadrant and facing the paint roller 31, on the one hand, the excess paint on the paint roller 31 can be scraped off well, and on the other hand, the scraped paint can be prevented from dripping onto the transmission mechanism 2.

[0035] like Figure 3 、 Figure 5 As shown, the scraping head 423 has a pointed structure, and the end face of the scraping head 423 close to the paint roller 31 extends vertically, which can better scrape off excess paint. The end face of the scraping head 423 away from the paint roller 31 is inclined, which is convenient for scraping off the paint on the one hand, and can pull the scraped paint into the material storage portion 422 on the other hand.

[0036] The adjusting component 41 includes a motor 411, a screw rod 412, a nut seat 413, a connecting plate 414 and a mounting seat 415. The mounting seat 415 is fixedly connected to the frame 1, the screw rod 412 is rotatably connected to the mounting seat 415, the output shaft of the motor 411 is transmission-connected to the input end of the screw rod 412, the motor 411 is used to provide power for the rotation of the screw rod 412, the nut seat 413 is threadedly connected to the screw rod 412, one end of the connecting plate 414 is fixedly connected to the nut seat 413, and the other end is fixedly connected to the scraper plate 42. Through the design of the adjusting component 31, the distance between the scraper plate 42 and the coating roller 31 can be controlled, thereby controlling the thickness of the applied coating. The screw transmission mechanism has high control precision.

[0037] When adjusting the position of the scraper 42, the motor 411 is started, and the motor 411 drives the screw 412 to rotate, thereby moving the nut seat 413, and the scraper 42 is driven to move by the nut seat 413, so that the scraper 42 can move closer to or away from the coating roller 31. The change of the moving direction of the scraper 42 is achieved by the forward and reverse rotation of the motor 411.

[0038] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
