Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printers, in particular to an anti-static brush component and an inkjet printer. Background Art

[0002] Inkjet printer is a device used to print text, patterns, barcodes and other information on the surface of products. It uses inkjet technology to spray ink onto the printed object to achieve fast and high-quality printing effects. Inkjet printers are widely used in packaging, food, pharmaceutical and other industries. During product processing, static electricity will accumulate charges on the surface of the printed product. If static electricity is not removed, static electricity will interfere with the ink jet path, resulting in reduced print quality. Therefore, static electricity needs to be removed from the printed object when the inkjet printer is working. By removing static electricity, the accumulation of static electricity on the surface of the printed object can be reduced, ensuring normal ink jetting and obtaining clear and accurate printing effects.

[0003] After searching, in the prior art, Chinese Patent Publication No.: CN219467365U discloses an inkjet printer. The utility model includes a base plate, two support plates are fixedly installed on the upper surface of the base plate, a movable plate is slidably installed in the support plate, a transverse plate is fixedly installed on the upper surface of the movable plate, a mounting plate is slidably installed on the upper surface of the transverse plate, and a spray terminal is fixedly installed on the lower surface of the mounting plate. In the utility model, the spray terminal is driven up and down by a motor to adjust the height of the spray terminal, and the spray terminal is driven left and right by a cylinder to adjust the position of the spray terminal, which is convenient for daily use. In the utility model, the fixed plate is driven to move by a double-headed screw so that the sides of the fixed plate that are close to each other are in contact with the two ends of the pipe, and the second limiting column is driven to move by the second screw rod so that the outer surfaces of the first limiting column and the second limiting column are in contact with the outer surface of the pipe, which is convenient for limiting pipes of different sizes.
