Abstract

The invention relates to the technical field of printing machines, in particular to a drying unit of a printing machine. The drying unit comprises a draught fan, a heat and an oven which are sequentially connected; the drying unit further comprises a baffle used for changing the area of an outlet of the oven, and the baffle is located at the outlet of the oven; and a drying agent is arranged at an outlet of the heater, and an adsorbent is further arranged at the outlet of the oven. The drying agent is arranged behind the heater, hot air can be dried, and the drying efficiency of the oven is improved. The adsorbent is arranged at the outlet of the oven, so that pollution of discharged gas to the environment is avoided. In addition, through the design of the baffle, the exhaust amount of the oven can be adjusted, and the using rate can be improved.

Description

Technical field [0001] The invention relates to the technical field of printing machines, and in particular to a drying device for printing machines. Background technique [0002] There is a certain amount of unabsorbed ink on the surface of the finished product printed by the existing printing machine, which is easy to paste off after being touched. Therefore, an oven is generally used to dry the printed matter. The existing oven mainly includes a fan and a heater, but during heating, the humidity of the hot air tends to increase, resulting in low drying efficiency. During the drying process, there will still be some harmful gases produced by the volatilization of organic components in the ink, which will cause environmental pollution to be directly eliminated. In addition, the existing oven often cannot control the air volume in the oven. Summary of the invention [0003] The purpose of the present invention is to provide a printing press drying device with high drying efficie...
