The invention relates to the field of packaging, and aims to provide a blister varnish coating machine and a blister varnish coating method. The blister varnish coating machine comprises a mounting base, a rubber roller pivoted to the mounting base at the two ends, a driven roller positioned at the lower side of the rubber roller, an oiling device, a conveying belt device positioned at the back side of the driven roller, a heating baking device and a cooling airing device positioned at the upper side of the conveying belt device and arranged in a front-back manner, a roll preventing pressure frame penetrating in the heating baking device and the cooling airing device, a loading plate opposite to the upper part of the front side of the driven roller at the back end and connected with the mounting base at the two side ends, a passing plate connected with the mounting base at the two side ends, and a rubber roller driving device, wherein the front end of the passing plate is opposite to the upper part of the back side of the driven roller, and the back end of the passing plate is opposite to the upper part of the front end of the driven roller. The blister varnish coating machine has the advantages of good uniformity and brightness of blister varnish coating a paperboard, high heating baking and cooling airing efficiency, clearness of characters and patterns due to difficult rolling and bonding of the paperboard and good blister effect.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a blister oil coating machine and a blister oil coating method. Background technique [0002] Many products are packaged and decorated in boxes made of cardboard with printed text patterns. In order to protect the products and make the text patterns printed on the packaging boxes clear and not covered, the packaging boxes are often covered with protective materials such as PVC and PET. layer; coating the plastic-absorbing oil on the cardboard for making the packaging box can make the packaging box and the protective layer fit well; A kind of cardboard blister oil and its preparation method have been understood; at present, because there is no suitable coating blister oil device, there are problems such as uneven coating of blister oil on cardboard, poor brightness, low efficiency of heating, baking and cooling air drying, and easy curling and sticking of cardboard Insufficient that the ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problems of uneven coating of blister oil on cardboard, poor brightness, low efficiency of heating, baking and cooling air-drying, and unclear characters and patterns caused by easy curling and sticking of cardboard due to the lack of suitable coating blister oil device. And the lack of plastic effect is poor, to provide a cardboard coated with plastic oil uniform brightness, high efficiency of heating and baking and cooling air-drying, cardboard is not easy to curl and stick, will not cause unclear text pattern and good plastic effect Blister oil coating machine and blister oil coating method
