Problems solved by technology

[0002] The domestic printing and packaging industry is developing rapidly, and the emission of organic solvents such as laminating machines and coating machines is increasing. Toluene in organic solvents has carcinogenic effects, and other organic solvents such as benzene, esters, and ketones have different degrees of environmental impact. pollution, affecting human health, and wasting resources
The use of water-based glue and water-based ink can effectively reduce the discharge of organic solvents, but the latent heat of evaporation of water is relatively large, resulting in slower volatilization, increasing the energy consumption of equipment, and affecting the printing and coating speed

Embodiment Construction

[0008] According to the general existence of ink and glue that the viscosity decreases when heated and the leveling property improves, the ink tank (or glue tank, ink storage barrel (or glue storage barrel)) is added with heating and constant temperature control functions, which can make the ink , glue, and paint are kept at a suitable temperature higher than room temperature, so as to ensure the leveling property, increase the solid content of ink, glue, and paint, thereby reducing the energy consumption of the drying box. For solvent-based inks , glue, paint, which not only saves energy, but also reduces the emission of organic solvents.

[0009] For water-based inks, glues, and paints, because water has a large latent heat of evaporation and is difficult to volatilize, in order to achieve the purpose of drying, the previous method is to increase the drying power and reduce the production speed, which affects the production efficiency and increases the cost. According to dif...

Abstract

The invention relates to an energy-saving printing and coating machine and an energy-saving method. In the technical scheme, a glue and ink supply system (an ink tank, a glue tank, an ink storage tank and a glue storage tank) is additionally provided with functions of heating and constant-temperature control to reduce the viscosity and to improve the solid content of the glue or ink, thereby achieving the energy-saving purpose. The invention belongs to the field of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to an energy-saving printing and coating machine and an energy-saving method, especially the improvement on the glue (ink) supply system of the printing and coating machine, belonging to the field of energy saving and emission reduction. Background technique [0002] The domestic printing and packaging industry is developing rapidly, and the emission of organic solvents such as laminating machines and coating machines is increasing. Toluene in organic solvents has carcinogenic effects, and other organic solvents such as benzene, esters, and ketones have different degrees of environmental impact. pollution, affecting human health and wasting resources. The use of water-based glue and water-based ink can effectively reduce the discharge of organic solvents, but the latent heat of evaporation of water is relatively large, resulting in slower volatilization, increasing the energy consumption of equipment, and affecting the printing an...
