Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment, specifically a novel roller coating device for aluminum-zinc alloy sheets. Background Technology

[0002] Aluminized zinc alloy sheet is mainly composed of aluminum, zinc and silicon. These components solidify at high temperature to form an alloy material. The corrosion resistance of aluminized zinc alloy sheet is one of its most significant characteristics. Due to the dual protection of aluminum and zinc, this sheet can maintain long-term stability in various environments. The production and processing of aluminized zinc alloy sheet requires roller coating shafts for auxiliary processing, which improves the processing efficiency and coating smoothness of the alloy sheet.

[0003] Application number CN218982137U discloses a roller coating device for aluminized zinc alloy plates. The device includes a machine body, which comprises a conveying mechanism for conveying the steel plate and a roller coating mechanism for roller coating the surface of the steel plate. The roller coating mechanism includes a second motor, a third motor, a first coating roller, a second coating roller, a rotating roller, and a first liquid storage tank. The second and third motors are fixedly connected to the machine body. The output shaft of the second motor is driven by the first coating roller, driving it to rotate. The output shaft of the third motor is also driven by the second coating roller, driving it to rotate. The first coating roller is positioned above the second coating roller, with its surface abutting against the upper surface of the steel plate, and the surface of the second coating roller abutting against the lower surface of the steel plate. This invention offers advantages such as double-sided coating and improved coating efficiency.

[0004] In existing technologies, double-sided coating is achieved through components such as conveying mechanisms and roller coating mechanisms. The conveying mechanism is used to transport steel plates and works with the first coating roller, the second coating roller, and the motor in the roller coating mechanism to perform the coating process. During the coating process, the positions of the first coating roller and the second coating roller are fixed and cannot be adjusted, which limits the thickness of the coating and thus restricts the application range of the roller coating device. At the same time, thick or thin coatings are prone to occur during the coating process, resulting in an uneven coating effect and affecting the coating effect. Utility Model Content

The scraper structure 3 includes a connecting plate 301, a support column 302, a telescopic spring 303, and a scraper 304.

[0027] The adjusting roller 202 is set up, and its position can be changed through the openings on both sides of the side plate 201 and the control handle 205. This makes the distance between the feeding roller 203 and the coating roller 204 and the adjusting roller 202 adjustable, so that the coating thickness of the board can be adjusted according to the actual situation, thereby expanding the application range of the device.

[0028] Additionally, a scraper structure 3 is provided. The scraper structure 3 is located on the rear side of the roller coating assembly 2 to scrape the surface of the plate. The scraper 304 is moved left and right by the telescopic springs 303 on both sides of the support column 302, so that the coating on the outside of the plate is smooth, ensuring the smoothness of the plate after roller coating, thereby improving the quality of the coating on the aluminum zinc alloy plate.

[0029] The base 101 has two sets of square platforms arranged side by side. The support plate is square and has connecting columns on both sides inside. The connecting columns are cylindrical and have several sets arranged at equal distances. The conveyor belt 102 is aligned with both ends of the base 101 and is of equal length. The back support roller 104 is a cylindrical roller and has several sets arranged at equal distances at the bottom of the roller coating assembly 2.

[0030] The side plate 201 has openings on both sides, which are square arc-shaped. The roller body includes an adjusting roller 202. On the same side of the adjusting roller 202, there is a feeding roller 203 and a paint roller 204. The adjusting roller 202 is cylindrical. The feeding roller 203 and the paint roller 204 are distributed vertically. The control handle 205 is connected to the adjusting roller 202, the feeding roller 203 and the paint roller 204 respectively.

[0031] The connecting plate 301 has two sets of oppositely distributed support columns 302 installed on the inner side of the connecting plate 301. A telescopic spring 303 is provided on one side of the support column 302, and a scraper 304 is installed on the top of the telescopic spring 303.

[0034] Working principle: During use, the conveyor belt 102 in the conveying structure 1 conveys the sheet material to the bottom of the roller coating assembly 2. The distance between the adjusting roller 202 and the feeding roller 203 is adjusted according to the thickness of the coating. The coating is applied to the surface of the sheet material by the rotation of the back support roller 104, the feeding roller 203 and the coating roller 204 and is conveyed to the bottom of the scraper structure 3. The scraper 304 moves by the action of the support column 302 and the telescopic spring 303 to perform the scraping work, thereby removing excess coating from the surface of the sheet material and smoothing the coating on the outside of the sheet material, so that the coating is evenly and smoothly covered on the surface of the sheet material, thereby improving the quality of the coating of aluminum zinc alloy sheet.
