Description

Technical Field

[0001] The utility model relates to the technical field of color-coated aluminum coils, in particular to a device for automatically adjusting the thickness of coatings for a color-coated line. Background Art

[0002] Color-coated aluminum coils, as the name suggests, are aluminum coils that have been painted and colored on their surface. Common ones include fluorocarbon color-coated aluminum coils, carbon color-coated aluminum coils, and polyester color-coated aluminum coils. They are widely used in aluminum-plastic panel industrial factory roofs and walls, aluminum blinds, composite panels, aluminum ceilings, cans, and electronic products.

[0003] For example, the patent document with application number 202323129524.4 discloses a steel plate color coating production line, including a box body, a feeding roller group is arranged at the inlet, a printing roller group 1 is arranged behind the feeding roller group, a nozzle 1 is arranged between the printing roller group 1 and the feeding silver group, a printing silver group 2 is arranged behind the printing roller group 1, a nozzle 2 and a drying device 1 are arranged between the printing silver group 2 and the printing roller group 1, a film material 1 is arranged behind the printing roller group 2, a pressing roller group 1 is arranged behind the film material roller 1, a drying device 2 is arranged between the pressing silver group 1 and the printing roller group 2, a guide roller 1 is arranged behind the pressing roller group 1, a film material roller 2 is arranged behind the guide roller 1, a pressing lifting group 2 is arranged behind the film material roller 2, a tension is arranged behind the pressing silver group 2, and a guide lifting group 2 is arranged behind the tension roller. The utility model can shorten the entire process and effectively improve the color coating efficiency.

[0004] For similar color coating production lines, there are impurities such as dust and fine particles in the environment around the production site. These impurities are attached to the surface of the aluminum coil through air transmission or other means. The presence of dust or other impurities on the surface of the aluminum coil will prevent the coating from being completely attached to the aluminum coil, resulting in uneven coating quality or shedding, affecting the appearance and quality of the product. In addition, the high viscosity of the coating will increase the flow resistance, making it difficult for the pressure roller to apply enough pressure to press the coating evenly onto the surface of the substrate, resulting in insufficient pressure, uneven adhesion between the coating and the film material, and blistering.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a device for automatically adjusting the coating thickness of a color coating line is proposed. Utility Model Content
