Problems solved by technology

[0004] However, the heating device of this plastic film printing machine uses a fan to blow the hot air generated by the heating plate, which will cause the hot air blown by the fan to be largely gathered on the printed graphics of the packaging bag, so that the drying area is not large enough. Uniform, drying effect is not good

Abstract

The invention provides a drying device of a packaging bag printing machine, and belongs to the technical field of printing. The technical problems such as instable drying and poor drying effect of the existing drying device of the printing machine are solved. According to the drying device of the packaging bag printing machine, the printing machine comprises a rack, as well as a plurality of guide rollers and a printing box which are arranged on the rack; the drying device comprises a heating box in which a cavity is formed, as well as a fan which is arranged at one side of the heating box; both the heating box and the fan are fixed to the rack; the heating box is internally provided with a plurality of electrical heating fins; an air outlet pipe of the fan is communicated with the cavity; an air outlet is formed in the other side of the heating box; the air outlet leads to a printed surface of the packaging bag through an air delivery pipe; and a clapboard in which a plurality of through holes are formed is arranged on the air outlet. The drying device is capable of effectively preventing hot air and greatly drying the printed patterns on the packaging bag, and is simple in structure and good in drying effect.

Description

technical field [0001] The invention belongs to the technical field of printing, and relates to a packaging bag printing machine, in particular to a drying device of the packaging bag printing machine. Background technique [0002] A printing machine is a machine for printing text and images. A modern printing machine is generally composed of plate loading, ink application, embossing, and paper feeding. On the printing press, the ink is applied manually or by the printing machine to the place where the text and images are on the printing plate, and then directly or indirectly transferred to paper or other substrates to reproduce the same print as the printing plate. At present, the application of printing machines in food packaging bags has become more and more extensive. [0003] However, after printing the food packaging bags, it is usually necessary to dry the printed graphics and texts by a drying device. After searching, for example, a Chinese patent document discloses...
