Description

Technical Field

[0001] The present invention relates to the technology in the field of UV printers, and in particular to an automatically rotatable UV printer for shoe uppers. Background Art

[0002] UV ink is an environmentally friendly ink that does not use solvents, has a fast drying speed, good gloss, bright colors, and strong water resistance. Applying UV ink to the printing field of furniture boards can effectively solve the risk of heavy metal exceeding the standard existing in the application of paint. UV printing is a printing process that dries and cures ink through ultraviolet light, and it requires the cooperation of ink containing photosensitizer and UV curing lamps. The application of UV printing is one of the most important contents in the printing industry. Metal paper cards, composite paper cards, aluminized paper, and paper cards with glazing treatment are being used more and more widely in the field of cosmetic packaging, showing a continuous and stable growth trend. New transparent composite materials have also begun to be used in plastic box packaging. Since these printing substrates cannot be printed by ordinary methods and must be achieved through UV technology to obtain the desired effects, not only more and more UV glazing is applied, but the use of UV printing ink is also more common. According to this trend, UV printing will become the standard configuration in the future, and completing a printing operation with stable quality will no longer depend on luck as before. A powerful sheet delivery and curing system is just the most basic configuration, and in-line curing is no longer a luxury equipment. These devices provide a broad application space for printing enterprises and can fully meet various special requirements of the cosmetic industry. The UV printing process mainly refers to achieving partial or overall UV printing effects on a UV printer using special UV ink. It is mainly suitable for printing non-absorbent materials, such as: gold card paper, silver card paper, pearlescent paper, transparent self-adhesive labels, plastics, PVC, PE, gratings, etc.

[0003] Most of the current UV printers for shoes on the market need to be adjusted manually for the position and angle of the shoes, and cannot process the inclined surface of the shoes fully automatically, which seriously reduces the production efficiency of shoes and increases the production cost of shoes. Moreover, the processing method of manually turning the shoes also results in a low qualified rate of products.
