Description

Technical Field

[0001] The utility model belongs to the technical field of paper production, and particularly relates to a sizing device for art cardboard. Background Art

[0002] In the modern printing and packaging industries, art cardboard is widely popular due to its unique texture, color, and decorative effects. To enhance the aesthetics and durability of art cardboard, a layer of glue or coating is usually applied to the surface of the cardboard. This process not only enhances the tear resistance of the cardboard but also provides protection such as waterproof and moisture-proof functions, while endowing it with rich visual effects.

[0003] However, when the existing sizing device is used for a long time, as the glue solidifies on the sizing roller, the diameter of the sizing roller gradually increases, resulting in a smaller gap between the sizing rollers, which affects the uniformity of paper sizing. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sizing device for art cardboard in view of the above existing technical problems, achieving the effect of improving the sizing uniformity of paper.

[0005] In view of this, the utility model provides a sizing device for art cardboard, including:

[0006] A frame, on which a front sizing roller and a rear sizing roller are arranged in sequence, and adjusting plates are arranged between the two sides of the front sizing roller and the frame;

[0007] Two motors, which are arranged on the side of the frame, and the output shafts penetrate the frame and are connected to the front sizing roller and the rear sizing roller;

[0008] A guiding roller, which is rotatably arranged on the frame and is located below the front sizing roller;

[0009] A cleaning assembly, which has two groups and is respectively arranged on the side of the frame and the top surface of the adjusting plate, and is respectively in contact with the surfaces of the front sizing roller and the rear sizing roller.

[0010] In this technical solution, the art cardboard passes through the gap between the front sizing roller and the rear sizing roller. Through the cooperation between the front sizing roller and the rear sizing roller, the art cardboard is sized, and the cleaning assembly can clean the surfaces of the front sizing roller and the rear sizing roller, which is beneficial to improving the stability of the device and the sizing uniformity.

[0011] In the above technical solution, further, the cleaning assembly includes:

[0012] Fixing plates, which are symmetrically arranged on the side of the frame, and support frames are arranged on the top surfaces of the fixing plates and the adjusting plates;

[0013] A spray pipe, which is installed on a support frame, and nozzles are evenly distributed along the axis direction of the spray pipe;

[0014] A scraper, which is arranged below the spray pipe, and a telescopic structure is arranged between the scraper and the fixed plate and the adjusting plate;

[0015] Wherein, a collection tank is arranged below the scraper.

[0016] In this technical solution, through the cooperation between the spray pipe and the nozzles, the cleaning liquid can be sprayed onto the surfaces of the front rubber roller and the rear rubber roller, and through the arranged scraper, the glue on the surfaces of the front rubber roller and the rear rubber roller can be cleaned, which is beneficial to improving the stability of the device and the uniformity of glue application. And through the arranged telescopic structure, the state of the scraper abutting against the outer surfaces of the front rubber roller and the rear rubber roller can be maintained, which is beneficial to improving the cleaning efficiency.
