Paper coloring device

Abstract

The invention relates to the technical field of papermaking equipment and in particular provides a paper coloring device, which adopts a process of drying, then coloring and then drying products. Dual guide rollers are adopted to drive blankets and operate in opposite directions to enable paper to be clamped between the blankets, and a paper coloring process is completed by spraying onto the blankets through pump circulation. The paper is prevented from being deformed and ruptured and is kept in an original state, and the color can be freely adjusted. Then, excessive coloring dye is absorbed by using a vacuum pump, the color of the paper is enabled to be uniform and bright, the quality is good, the dye cost is low, the dye is enabled to be circulated in a coloring tank, can be collected and utilized and does not leak outside, and the pollution is precluded. The equipment cost is low, the operation is simple, the coloring speed is fast, the output is high, the situation that a great amount of wastewater is produced due to pollution caused by the dye is precluded, the sewage treatment expense is reduced, the safety performance is good, no potential hazard exists, and the device is very good novel, environmental-friendly, energy-saving equipment which benefits the nation and the people at present.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to the field of coloring, and relates to a paper coloring device of baking paper technology. Background technique [0002] Over the past 5,000 years in China, the progress of culture, the development of society, and the invention of papermaking have been applied in many places. From ancient handicraft workshops to mechanized papermaking in recent decades, the investment is heavy, the production cost is high, and the environment is polluted. In particular, colored paper such as yellow paper and red paper is applied to the fireworks and firecracker industry, and the ethnic customs for thousands of years, weddings and funerals, opening ceremonies and other places are indispensable. If mechanized drying is used for production, the cost is high, the surface of the paper is too smooth, there is no strength and thickness, and the investment is large, the process is complicated, the pow...

Problems solved by technology

[0003] On the premise that the existing background technology is insufficient, the patent of the present invention designs a paper coloring device, which can complete the paper coloring process at the same time as production. The equipment is cheap, and the secondary pollution of water is reduced. Pigments or chemical raw materials can be collected and recycled, which is safe and has no hidden dangers, and the production cost is low, which solves the big problem of major water pollution
