Printing presses with stable web

Abstract

The invention discloses a printing machine stable in paper winding. The printing machine comprises a machine base (1), wherein a workbench (2) is arranged on the machine base (1); paper winding units (3) are arranged at the two sides of the workbench (2); the two ends of the two paper winding units (3) are respectively connected with cantilevers (4) and support units (5); drive motors (6), driving wheels (7), driving belts (8) and driven wheels (9) are arranged on the cantilevers (4); the driven wheels (9) are connected with the paper winding units (3); the support units (5) comprise support frames (51); support shafts (52) are arranged at one sides of the support frames (51); extension bases (53) are arranged at the bottoms of the support frames (51); one ends of the extension bases (53) are connected with bolts (54); mounting bases (10) are arranged at the two sides of the workbench (2); waist-shaped holes (11) are formed in the mounting bases (10). The printing machine can achieve the effect of improving the paper winding stability, is convenient to use and also has the advantage of wide range of application.

Description

technical field [0001] The invention relates to a printing machine, in particular to a printing machine with stable web. Background technique [0002] In the existing printing machines, a paper roll mechanism is generally required to feed and rewind the paper, so that the printing paper passes through the surface of the workbench; generally, the paper core is connected to the paper core through the paper roll and drives the paper core to rotate, so that the paper on the paper feed roll The printing paper is sent out, and the printing paper is rewound by the take-up reel; when the paper is rolled, the clips are clamped from both sides of the paper feed reel and the take-up reel. However, when the existing printing machine rolls the paper, the clamping stability is poor, which leads to the deviation of the paper core and the unsatisfactory stability of the roll paper. Moreover, the existing printing machine can only be installed with a paper core with a specified diameter whe...

AI Technical Summary

Problems solved by technology

However, when the existing printing machine rolls the paper, the clamping stability is poor, which leads to the deviation of the paper core and the unsatisfactory stability of the roll paper

Moreover, the existing printing machine can only be installed with a paper core of a specified diameter when winding paper. When winding paper cores with different diameters, it is necessary to replace the winding roll or add an auxiliary sleeve of the corresponding specification, which is inconvenient to use and has a small scope of application.

Therefore, the existing printing machines have the problems of unsatisfactory roll paper stability, inconvenient use and small application range.
