Description

Technical Field

[0001] The present application relates to the technical field of label printing equipment, and in particular to a high-reliability UV inkjet printing equipment for labels. Background Art

[0002] Labels are commonly seen in supermarkets and other shopping malls, primarily displaying product information. Currently, UV inkjet printing is gaining widespread attention and adoption in the label printing industry due to its environmental friendliness and efficiency. UV inkjet printing utilizes a combination of ultraviolet curing technology and inkjet printing to precisely apply ink to various surfaces, rapidly curing the ink and creating a high-quality, durable print.

[0003] Traditional UV inkjet label printers usually adopt a single nozzle design and adapt to label paper of different thicknesses by adjusting the ink droplet size. Although this method can adapt to uneven thickness materials to a certain extent, due to the lack of dynamic adjustment function, problems such as unclear printing will still occur when encountering particularly rough or uneven surfaces. Therefore, improvements are now being made to a high-reliability UV inkjet printing device for labels. Utility Model Content

[0015] As a preferred technical solution of the present application, the ultraviolet curing unit includes a mounting frame fixedly mounted on the upper surface of the workbench, the inner top wall of the mounting frame is provided with a placement groove, and two ultraviolet lamps are fixedly mounted inside the placement groove.

[0016] By adopting the above technical solution, the ultraviolet lamp emits an ultraviolet beam, causing the light-curing resin in the ink to undergo a chemical reaction, rapidly changing from liquid to solid, firmly adhering to the label surface.

[0017] As a preferred technical solution of the present application, the console is electrically connected to the intelligent recognition unit, the ultraviolet curing unit, the two driving motors and the two UV inkjet device bodies respectively.
