Adjustable rolling device of printer

Abstract

The invention discloses an adjustable rolling device of a printer. The device comprises a left vertical plate and a right vertical plate opposite to the left vertical plate, and further comprises two clamping bases, bearings are arranged in the clamping bases, and the bearings are arranged at the two ends of a paper rolling shaft. The upper right portion of the left vertical plate and the upper right portion of the right vertical plate are provided with multiple opposite trapezoid clamping grooves clamped with the clamping bases, paper guide rollers include the first paper guide roller, the second guide roller and the third guide roller, and the upper rear portion of the left vertical plate and the upper rear portion of the right vertical plate are respectively provided with two semicircular installation holes and one round installation hole. Two paper guide rollers are installed in the semicircular installation holes, the heights of the two paper guide rollers can be adjusted conveniently, and tension force can be adjusted with the other paper guide roller; the paper rolling shaft has three trapezoid adjusting gears so as to have different tension forces, printed paper become more compact after being rolled, and rolling is more stable.

Description

technical field [0001] The invention relates to a printing machine, in particular to a tension-adjustable winding device arranged on one side of the printing machine. Background technique [0002] A printing press is a machine that prints text and images. Modern printing machines are generally composed of plate loading, ink application, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Print onto paper or other substrates such as textiles, sheet metal, plastic, leather, wood, glass, and ceramics to reproduce the same print as the printing plate. [0003] A winding mechanism is provided on one side of the printing machine, through which the printed printing paper ca...

AI Technical Summary

Problems solved by technology

However, in the existing winding mechanism, the paper guide roller and the paper reel are all fixed. When the printed paper is sorted into rolls, the position of the printed paper is easily shifted, the printed paper is loose, etc., which is not convenient for the subsequent sorting of the printed paper. , the whole roll of printing paper is loose, which is not convenient for loading and unloading and subsequent cutting work
