Abstract

The invention discloses a paper smoothing and conveying device for flat-plate printing. The paper smoothing and conveying device comprises a mounting frame, conveying rollers, a conveyor belt, a firstsmoothing assembly, a second smoothing assembly and a third smoothing assembly, wherein the conveying rollers are rotationally arranged at two ends of the mounting frame; the first smoothing assemblyis arranged on the mounting frame; a mounting plate is arranged at the paper outlet end of the mounting frame; the second smoothing assembly is arranged on the mounting plate; and the third smoothingassembly is arranged below the second smoothing assembly. According to the paper smoothing and conveying device for flat-plate printing, by arranging the first smoothing assembly, an air supply partblows printing ink and cool paper at the same time, so that the deformation is reduced; a first smoothing roller presses the protruding part of the deformed paper so as to restore part of deformation;by arranging the second smoothing assembly, a first rotating roller, a second smoothing roller and the conveying rollers at the paper outlet end press the concave part of the deformed paper so as torestore part of the deformation; and by arranging the third smoothing assembly, so that a third smoothing roller presses the two sides of the paper, the deformation is further avoided, therefore, thepaper is stiff and smooth, and finally, the purpose of smoothing the paper is achieved.

Description

technical field [0001] The invention relates to the field of printing, in particular to a paper smoothing conveying device for flat printing. Background technique [0002] Printing is a technology that transfers the ink to the surface of paper, fabric, plastic, leather and other materials through plate making, ink application, and pressurization to copy the contents of the original manuscript in batches. In the existing paper printing technology, the paper will be heated and bent under force during the printing and transmission process. The paper obtained after printing often has a certain angle of bending, and it is impossible to obtain a flat as new paper, which will affect the subsequent process. Reduce production efficiency. [0003] In order to solve the above problems, the present application proposes a paper smoothing conveying device for offset printing. Contents of the invention [0004] (1) Purpose of the invention [0005] In order to solve the technical prob...
