Abstract

The invention provides a presswork dampening device. The device comprises supports, a motor, a main rotary shaft, an auxiliary rotary shaft, a steam generator, a water inlet pipe and a conveying belt.A water inlet valve is arranged on the water inlet pipe. The motor drives the main rotary shaft to rotate, and accordingly, the auxiliary rotary shaft is driven. The presswork dampening device further comprises a humidity sensor used for detecting presswork humidity. The steam generator is provided with a plurality of air guide pipes. A regulating valve is arranged on each air guide pipe. An exhaust pipe is arranged on the air guide pipes in a communicating mode and perpendicularly arranged below the conveying belt. A plurality of air spray holes are formed uniformly in the upper portion of the exhaust pipe. According to the presswork dampening device, since the humidity sensor is arranged, a steam control module and a time adjusting button are arranged in the steam generator, the steam spray-out amounts can be effectively controlled, the paper presswork dampening effect is made better, the paper presswork yield is greatly increased, the production efficiency is improved, and the production cost is lowered.

Description

[0001] 【Technical field】 [0002] The present invention relates to the technical field of supporting facilities for printing machinery, and more specifically, relates to a printing matter wetting device. [0003] 【Background technique】 [0004] At present, in the production process of paper printed matter, the printing pattern on the surface of the printed paper output from the printing machine is generally still in a non-drying state. In order to make the paper dry quickly, a A heating and drying device, through the heating and drying of the heating and drying device, the paper is dried quickly. During the reheating and drying process of paper printed matter, the paper fiber moisture of paper printed matter will be lost, which will lead to stretching and deformation of paper printed matter, resulting in brittle edges of paper printed matter. Usually, it will be wetted by wetting device after heating and drying. , the existing wetting device can not detect the humidity of pa...
