Description

Technical Field

[0001] The invention relates to the technical field of printer accessories, and in particular to an inkjet head cleaning device. Background Art

[0002] The inkjet head of an inkjet printer may be clogged due to long-term operation, affecting the printing effect. In order to keep the inkjet head clean, it is necessary to use a cleaning device to clean it regularly. In the prior art, the cleaning device of the inkjet head is usually an ink suction box. When the inkjet head moves to the ink suction box, the ink suction box can effectively absorb and remove the ink remaining in the inkjet head and unclog the nozzle. For example, the utility model patent with announcement number CN214396003U discloses a high-speed flatbed UV printer, including a base, a printing table and a transmission module are movably arranged on the top of the base, the printing table is movably connected to a support table, and an ink suction box is fixedly installed on the top of the support table. After printing is completed, the printing module is moved to the ink suction box on the top of the support table to clean the print nozzle.

[0003] However, the ink pads made of rubber are mostly used for sealing between the inkjet head and the ink absorption box. After long-term use, the ink pads are prone to deformation or corrosion, and the connection between the inkjet head and the ink cartridge may be loose. When the ink absorption box generates suction to absorb excess ink in the nozzle, it may cause slight displacement of the inkjet head and cause shaking, resulting in poor sealing between the ink absorption box and the inkjet head, affecting the cleaning of the inkjet head. Summary of the invention

[0004] The purpose of the present invention is to provide an inkjet head cleaning device designed to address the deficiencies of the above-mentioned technology.
