Air-controlled thermostatic printing ink roller for printing

Abstract

The invention provides an air-controlled thermostatic printing ink roller for printing, and relates to the technical field of printing. The air-controlled thermostatic printing ink roller comprises anink roller, wherein an ink cavity is formed in the middle of the ink roller, a heating sheet is fixedly connected to the inner wall of the ink roller, and an air cavity is formed in the inner wall ofthe left side of the ink roller. According to the air-controlled thermostatic printing ink roller for printing, the air cavity and a conductive block are matched for use; in an initial state, a circuit of the heating sheet is switched on, and the ink in the ink cavity is heated; at the same time, a heating sheet at the bottom of the air cavity simultaneously heats the air at the bottom of a piston block, so that the air expands to upwards push the piston block; when the heating sheet is heated to a certain temperature, the circuit of the heating sheet is switched off; when the temperature ofthe ink cavity is decreased, the temperature of the air in the air cavity drops and contracts, the piston block descends, the conductive block is connected with the electric ring again, the circuit ofthe heating sheet is switched on, and the heating sheet is heated to the specific temperature again, so that the constant temperature effect of air holes is achieved, the ink is effectively ensured to be in the most suitable state, and the printing quality is improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an air-controlled and constant-temperature printing ink roller for printing. Background technique [0002] Printing is to transfer the ink to the surface of paper, fabric, plastic, leather and other materials through plate making, ink application, pressure and other processes to copy the content of the original manuscript in batches. The process of transferring the approved printing plate to the substrate through printing machinery and special ink. [0003] In the printing process, ink is an indispensable raw material. In the printing process, the temperature of the ink can affect the shape of the ink. When the temperature is too low, the ink may be too dry and the ink is difficult to discharge. When the temperature is too high, the consistency of the ink If the ink is too thick, the ink cannot be dried in time, causing the printed matter to appear mushy. No matter whether the ...

[0003] In the printing process, ink is an indispensable raw material. In the printing process, the temperature of the ink can affect the shape of the ink. When the temperature is too low, the ink may be too dry and the ink is difficult to discharge. When the temperature is too high, the consistency of the ink If the ink is too thick, the ink cannot be dried in time, causing the printed matter to appear mushy. No matter whether the ink is too dry or too thick, it will greatly affect the production efficiency. Therefore, the constant temperature heating of the ink needs to be solved urgently.
