Technical Field
[0001] This utility model relates to the field of industrial inkjet technology, specifically a UV printhead cleaning machine. Background Technology
[0002] Industrial inkjet printing is a technology that precisely sprays ink or other functional liquids through a printhead onto the surface of various materials to create specific patterns, logos, functional coatings, etc. It has a wide range of applications. For example, in the packaging and printing industry, it can quickly and accurately print exquisite patterns and text on cartons and boxes to meet the diverse packaging needs of products. Compared with traditional printing methods, it can achieve personalized customization, switch between different printing content at any time, and is faster, greatly improving the efficiency of packaging and printing. Printhead cleaning is an important part of the industrial inkjet industry. Its purpose is to ensure the normal operation of the printhead to maintain high-quality printing results.
[0003] The installation of nozzles is cumbersome, requiring operators to spend a lot of time and effort to fix them, resulting in low efficiency and safety issues such as nozzle loosening and cleaning fluid leakage. Cleaning machines are all fixed and integrated, lacking flexibility and unable to target different types of nozzles for specific cleaning, easily leading to incomplete cleaning or damage to the nozzles. Circulating cleaning lacks effective suction methods, failing to deeply clean the inside of the nozzles, leaving residual dirt that affects nozzle performance and lifespan. Room temperature cleaning is ineffective against stubborn stains, and the lack of pump speed adjustment and nozzle cleaning effect monitoring functions makes it difficult for operators to monitor the cleaning process in real time. Adjusting the nozzle height is also difficult, resulting in poor cleaning results. Therefore, this application proposes an alternative technical solution to address these problems.
