Problems solved by technology

This kind of backing paper force mechanism of printing press uses gear transmission and motor as the transmission mechanism and power mechanism. Due to equipment manufacturing reasons, in the actual use process, due to power and transmission problems, the shaft will vibrate irregularly. This vibration brings Tension fluctuations on backing paper

Abstract

The invention discloses a tension device of a printing machine. The tension device of the printing machine comprises a rack (9), wherein two ends of the rack (9) are provided with a rotating shaft (4)through supporting seats (6); the rotating shaft (4) is wound with a lining paper (8), and a gear transmission mechanism (3) is installed at one end of the rotating shaft (4); a support (7) which extends out and is perpendicular to the rack (9) is arranged on one side of the rack (9), and a magnetic powder brake (1) is installed on the support (7) through a seat (2); and an output shaft of the magnetic powder brake (1) is coaxially installed with a driven wheel of the gear transmission mechanism (3), and a tension control device (5) for controlling the tension of the magnetic powder brake (1)is installed on one side of the rack (9). The tension device of the printing machine has the advantages that defects in the prior art can be overcome, and the structure design is reasonable and novel.

Description

technical field [0001] The invention relates to a tensioning device of a printing machine, belonging to the field of printing machinery. Background technique [0002] Printing press, a machine used to print words and images. Modern printing machines are generally composed of plates, inking, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first, the text and images to be printed are made into printing plates, which are installed on the printing press, and then the printing press applies ink to the places with the text and images on the printing plate, and then directly or indirectly transfers them to the 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] During the printing process of the printing machine, lining paper is usually added to the printing plate and the roller to increase the thickness of the roller lining, t...
