Both-side printing equipment for medical paper-plastic bag production

Abstract

The invention discloses both-side printing equipment for medical paper-plastic bag production, and relates to the technical field of medical paper-plastic bags. The equipment comprises a base. The twosides of the upper end of the base are symmetrically provided with two side plates. A baffle is arranged at the portions, below the front portion of an unreeling roller, of the inner sides of the side plates. A first sweeping plate is arranged at the portion, at the front side of the baffle, of the inner sides of the side plates. A first guiding roller is arranged below the front sides of the first sweeping plate. A first auxiliary plate is arranged over the first guiding roller. Surface treatment is performed on the two side faces of a paper-plastic bag through the sweeping plate before printing, air-drying treatment is performed at the printed position by means of a cooling mechanism, meanwhile, by cooperatively using the adjustable auxiliary plate and a printing roller, the position ofthe auxiliary plate can be conveniently adjusted, and therefore the problem that when the paper-plastic bag and the printing roller are in contact printing, printing is not clear enough due to the influence of stretchable tension of the paper-plastic bag is avoided. The both-side printing quality of the paper-plastic bag is improved, and the both-side printing speed of the paper-plastic bag is increased.

Description

technical field [0001] The invention relates to the technical field of paper-plastic bags for medical use, in particular to double-sided printing equipment for the production of paper-plastic bags for medical use. Background technique [0002] The plastic composite film on one side of the medical paper-plastic bag is used for the packaging of medical devices to be sterilized. It belongs to the initial inner packaging of the product. The paper of the packaging bag generally needs to print the relevant information of the manufacturer or product of the medical device, which is produced in the paper-plastic bag. During the process, the relevant information of these products needs to be printed on both sides of the paper-plastic bag, so that it is convenient for users to understand and use. [0003] In the existing printing production process of medical paper-plastic bags, most of the paper-plastic bags need to be printed on one side, and then the other side is printed, and a sma...

AI Technical Summary

Problems solved by technology

[0003] In the existing printing production process of medical paper-plastic bags, most of the paper-plastic bags need to be printed on one side, and then the other side is printed, and a small number of paper-plastic bags are printed on both sides at the same time, but the printing effect is not ideal. And in the printing process, due to the stretching tension of the paper-plastic bag, when the printing roller is in contact with the surface of the paper-plastic bag, the printing is not clear enough due to the tension, and the surface of the paper-plastic bag is easy to print before printing in the production workshop. Falling dust and impurities will have a certain impact on the printing effect
