Paper deformation prevention printing device of packaging printing machine

Abstract

The invention relates to the technical field of printing, in particular to a paper deformation prevention printing device of a packaging printing machine. The paper deformation prevention printing device comprises a printing mechanism and a paper pressing mechanism arranged at the left part of a printing component; the paper pressing mechanism comprises two sets of paper pressing frames inclining downwards, a fixed concave frame fixedly connected to the upper side of the position between the two paper pressing frames, an adjusting screw penetrating through the middle of the fixed concave frame in a threaded mode, an adjusting concave frame rotationally connected to the bottom end of the adjusting screw, and pressing rollers rotationally connected into the adjusting concave frame through pressing shafts; and a lower driving mechanism is arranged on the front side of the front paper pressing frame, an upper driving mechanism is arranged on the front side of the adjusting concave frame, and a plurality of sets of lower roller pieces are rotationally connected between the two paper pressing frames at equal intervals. According to the paper deformation prevention printing device, hard paper is rolled and flattened through the pressing rollers and heat conduction pipes, pressing on the hard paper is achieved through the heat of the heat conduction pipes, then flattening treatment on the hard paper is achieved, deformation of the printed hard paper can be avoided to a certain extent, and then the subsequent packaging effect on the hard paper is improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printing device for preventing paper deformation of a packaging printing machine. Background technique [0002] Paper has a long history, and the use of paper is ubiquitous in our lives, so the paper production industry is becoming more and more developed. In the field of packaging, paper can also be used for packaging, usually some hard paper is printed, and then the hard paper is wrapped around the item. Due to the fast degradation speed of rigid paper, it is widely used in the packaging industry. [0003] At present, when the current packaging and printing equipment prints hard paper, it is easy to cause deformation of the printed hard paper, thereby affecting the subsequent packaging effect of the hard paper. Contents of the invention [0004] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a printing device for prev...
