Description

Technical Field

[0001] The utility model relates to the technical field of card printers, in particular to a cleaning wheel mechanism for a card printer. Background Art

[0002] A retransfer card printer consists of a ribbon and a retransfer film. A digital thermal head (TPH) with multiple linear heat sources heats the dye on the ribbon, vaporizing it and transferring it to the retransfer film via thermal sublimation. The retransfer film then moves to the transfer area, where it is aligned with the card using a heated roller module and a card drive roller mechanism. The heated rollers then apply pressure and heat to transfer the image from the film to the card. This card printer has strict requirements for the surface cleanliness of the print media, whether plastic or paper, which significantly impacts print quality.

[0003] A search revealed CN220995927U, which discloses a card printer cleaning wheel mechanism comprising an outer shell, characterized in that a cleaning wheel body is symmetrically mounted near the upper and lower ends of the inner portion of the outer shell, the cleaning wheel body being rotatably connected to the outer shell body, a card inlet being provided on one side of the outer shell body, and a card outlet being provided at the opposite end of the outer shell body, a bidirectional screw being provided behind the cleaning wheel body in the direction of card entry and discharge, the bidirectional screw being disposed near the rear side of the outer shell body, the bidirectional screw being rotatably connected to the outer shell body, a threaded sleeve being symmetrically mounted near the upper and lower ends of the bidirectional screw body, the threaded sleeve being threadedly connected to the bidirectional screw body, the threaded sleeve being slidably connected to the outer shell body, a connecting frame being fixedly mounted on one side of the threaded sleeve body, a scraper being mounted on the connecting frame, the scraper being parallel to the cleaning wheel body. In the utility model, by turning a first knob, the bidirectional screw body is driven to rotate, thereby driving the two threaded sleeves to slide, causing the scraper to contact the cleaning wheel body to scrape away dust and impurities on the cleaning wheel body.

[0004] However, in the process of using a scraper to clean the cleaning wheel, dust and impurities generated will accumulate in the outer shell. These accumulated dust and impurities can easily contaminate the card again, so there is room for improvement. Utility Model Content
