Water-based ink drying device for film bag printing

Abstract

The invention provides a water-based ink drying device for film bag printing. The water-based ink drying device comprises a fan, a drying oven and an electric cabinet. An air outlet cylinder and an air inlet cylinder are arranged on the fan; an air outlet and an air inlet are formed in the drying oven; the air outlet cylinder of the fan is connected with the air inlet of the drying oven, and the air inlet cylinder of the fan is connected with the air outlet of the drying oven; and the electric cabinet controls the fan. The fan and the drying oven form internal circulation of air, so that a film bag runs more smoothly and stably in drying equipment, meanwhile, the film bag is dried more uniformly by hot air, the drying effect on the film bag is qualitatively changed on the whole, further, the heat loss can be reduced by the internal circulation form of the hot air, the energy consumption can be reduced to a certain extent, and the production cost is reduced.

Description

technical field [0001] The invention relates to drying equipment for blow molding production, in particular to a water-based ink drying device for plastic film processing. Background technique [0002] Film bag is a kind of plastic bag, and film bag is the most widely used plastic bag on the market at present. It has good transparency and luster; it has good air tightness and fragrance retention; Humidity drops. Plastic film has excellent mechanical properties, and its toughness is the best among all thermoplastics. [0003] The production of film bags is generally realized by blow molding equipment. The plastic raw materials are heated and melted, and then the cylindrical plastic film is blown out through the blow molding machine head, and then one side is sealed to realize the production of the basic shape of the film bag. . In the production process of film bags, it is often encountered that customers customize film bags. It is necessary to print patterns or characters...

AI Technical Summary

Problems solved by technology

There are great disadvantages and deficiencies in the setting method of this drying box, such as the poor support effect of the roller shaft on the film bag, the blowing of the hot air to the film bag is not uniform enough, and the film bag is easy to break out under the action of the hot air and the roller shaft. Shaking and curling will affect the effect and quality of printing, and it is not conducive to the winding work of the film bag after printing
