Printing medium flattening device of printer and printer

Abstract

The invention provides a printing medium flattening device of a printer. The printing medium flattening device comprises a rack, a paper feeding end brush roller, a printing panel and a paper discharging end brush roller, and the paper feeding end brush roller, the printing panel and the paper discharging end brush roller are arranged on the rack; the paper feeding end brush roller and the paper discharging end brush roller both comprise roller bodies and brushes densely distributed on the surfaces of the roller bodies, the paper feeding end brush roller is arranged on the paper feeding side of the printing panel, and the paper discharging end brush roller is arranged on the paper discharging side of the printing panel; and a plurality of parallel grooves are formed in the printing panel, a boss is formed between every two adjacent grooves, the upper surfaces of the bosses are located on the same horizontal plane, and ventilation holes are densely distributed in the printing panel. The printing medium flattening device of the printer has the advantages that a good flattening effect on a thin medium is achieved, and excessive deformation of the thin medium after printing is avoided.

Description

technical field [0001] The invention relates to the field of printers, in particular to a printing medium flattening device of a printer. Background technique [0002] Printing machine is a kind of printer, which has been widely used in textile, home improvement, building materials, decoration and other fields. [0003] Take the field of home improvement and textiles as an example, such as curtains, quilt covers, sheets and other products, the current main printing and dyeing method is realized by rolling printing. The mold pattern on the rolling printing is glued with dye and printed on the fabric to form Patterned products. [0004] This roll printing method is relatively backward and requires a large amount of ink, which leads to more pollution in the printing and dyeing process, which is not conducive to environmental protection. In addition, the image unit produced by the roll printing method is small and the repetition is too high. Low-end, it is difficult to form co...

Problems solved by technology

[0006] However, in the thermal transfer process, the cost of the transfer medium-transfer paper has become an obstacle that limits the application of printing machines. In order to pursue profits and improve product competitiveness, material manufacturers make transfer paper thinner and thinner. High-quality paper can reduce costs, but the defects of thin paper are also very obvious. During the printing process, thin paper is easily stretched and deformed, especially after printing is completed, ink soaks the paper, and the paper is under a certain tension. , microscopic wrinkles are prone to occur, and such wrinkles are almost unavoidable
