Aluminum foil paper printing device

Abstract

The invention relates to a printing device for a soft-box packaging unit in the tobacco industry. The printing device comprises an aluminium paper roll, an aluminium paper transmission device, an aluminium paper guide roller set and an aluminium paper direction guiding device, wherein the aluminium paper guide roller set consists of a plurality of paper guide rollers which are arranged in the aluminium paper transmitting direction and sequentially numbered in the aluminium paper running direction from the paper guide roller close to the aluminium paper roll, and an aluminium paper printing roller is arranged near to one of the paper guide rollers. The printing device is characterized in that the aluminium paper printing roller comprises a steel seal roller, a steel seal arranged at one end of the steel seal roller and a cylinder component arranged at the other end of the steel seal roller and enabling the printing roller and the paper guide roller to be in close contact. Owing to the structure, the aluminium-foil paper printing device has the advantages of long service life, reduction of steel seal consumption and clarity in printing.

Description

technical field [0001] The invention relates to the field of soft box packaging units in the tobacco industry, in particular to a printing device of the packaging unit. Background technique [0002] In the tobacco industry, the aluminum paper conveying device in the commonly used soft box packaging unit is as figure 1 shown. The aluminum paper conveying device includes an aluminum paper roll 1 , an aluminum paper transmission device 2 , an aluminum paper guide roller set 3 and an aluminum paper direction guiding device 4 . Among them, the aluminum paper transmission device 2 includes an aluminum paper transmission gear 25 and an aluminum paper transmission wheel shaft 26; the aluminum paper guide roller group 3 is composed of a plurality of paper guide rollers, and the paper guide rollers start from the aluminum paper roll 1 along the running direction of the aluminum paper in sequence The numbers are the first paper guide roller, the second paper guide roller, the third p...

Problems solved by technology

[0004] The stencil of the above-mentioned aluminum foil paper printing device is set on the third paper guide roller, and the stencil is pressed and rolled on the position of the aluminum paper stencil. Due to the large contact surface of the integrated stencil, the rubber roller 29 is controlled by a tension spring, and the tension is uneven, resulting in the stencil. The printing is not clear, and the aluminum paper is smashed

After such packaging is sold, it will be mistaken as "fake cigarettes" and receive complaints and market feedback, which will directly affect the social reputation of the product

[0005] In addition, the integrated steel stamp is adopted, and shifts cannot be replaced separately. The entire steel stamp needs to be replaced every month or every month, resulting in waste of steel stamps. The steel stamp is installed on the third paper guide roller. The paper guide roller must be equipped with a shaft to install the steel stamp. The matching shaft cannot be used, resulting in waste of the aluminum roller transmission shaft

[0006] Since the steel stamp needs to be replaced every month, the steel stamp fixing hole and the steel stamp roller socket must be ground and matched to be installed in place. Every time the shift is changed, the entire multi-character conjoined steel stamp needs to be removed, which makes replacement difficult and takes a long time to adjust.

Moreover, according to the process requirements, the aluminum paper steel stamps are now required to be replaced every shift, which will cause a greater impact on production, and the hidden dangers caused by improper adjustment will be even greater.
