Description

TECHNICAL FIELD

[0001] The utility model relates to iron sheet printing technical field, especially iron sheet high fidelity printing dust removal equipment. BACKGROUND

[0002] Iron sheet printing, simply referred to as "iron printing", is a method of printing graphics on metal materials such as iron sheet or aluminum sheet. High-fidelity printing is relative to four-color printing. It improves the reproducibility and authenticity of printed colors by adding red, green, blue, and orange inks to the C, M, Y, and K four-color printing. To ensure the quality of high-fidelity printing, the surface of the iron sheet needs to be kept clean. However, dust will inevitably fall on the surface of the iron sheet during storage. Therefore, before high-fidelity printing, the surface of the iron sheet needs to be dusted, which requires the use of dust removal equipment.

[0003] In the Chinese patent CN221476456U, an environmental protection dust removal equipment for printing iron printing is disclosed. The environmental protection dust removal equipment for printing iron printing places the iron product to be printed on the first conveyor. The first conveyor moves the iron product. When the iron product moves between the first cleaning roller and the second cleaning roller, the second motor and the first motor are started. The second motor and the first motor drive the first cleaning roller and the second cleaning roller to rotate. The first cleaning roller and the second cleaning roller can lift the dust on the upper and lower ends of the iron product. The first fan is started, which can suck away the dust to prevent it from affecting the printing of the iron product and causing waste due to the impact on the printing quality in the later stage.
