Description

Surface gloss oil coating device for packaging box printing

Technical Field

Background

The polishing process after printing the corrugated packaging box refers to a process of coating a layer of water-based surface gloss oil on the surface of a printed pattern of the packaging box so as to form protection on the printed pattern on the surface. The process not only can enable the surface of the printed image and text to have the effect of reflecting light and increase the grade of products, but also can enable the surface of the printed image and text to have the effects of wear resistance and moisture resistance and improve the reliability of the packaging box in use, especially for the printed packaging box printed by intaglio printing, the implementation of the glazing process can form strong protection on the printed image and text protruding out of the surface. In the prior art, a gloss plate method is generally adopted to polish and oil the graphics on the surface of the packaging box. The control of the gloss plate pressure in the process is important, the gloss oil covers the image-text surface at the ridge peak because the corrugated packaging box surface has the uneven phenomenon, and the gloss oil cannot be protected at the Yu Lenggu position at the ridge peak position because the gloss oil is smaller. The polishing pressure is larger, and the corrugation can be crushed, so that the compression strength of the packaging box is affected.

In the prior art, the polishing pressure is often controlled by pushing and pulling the polishing plate to be close to the surface of the packaging box on the working platform through a pressure pushing cylinder, so that the pressure of the rubber scraping plate on the surface of the packaging box when the polishing plate is polished is increased or reduced. When the method is used for adjusting the polishing pressure, the push-pull force of the air cylinder is not easy to control, and the pressure value of the polishing pressure changes greatly when the scraping plate is in a moving state relative to the packaging box, so that the adjustment operation becomes difficult, and the pressure value of the polishing pressure is generally recorded and adjusted in a low-speed running or stopping state in the industry. Furthermore, when the polishing pressure is too high, excessive polishing oil can sometimes flow into the non-image-text part on the box body along the gaps between the ridges and the valleys, so that the surface of the box body is polluted.
