Description

TECHNICAL FIELD

[0002] The printing machine is a machine for printing characters and images, and is the core equipment of the printing industry. In the modern printing industry, the quality of printing directly affects the market competitiveness of products, and the accurate control of paper tension is one of the key factors to ensure the quality of printing. In the printing process, the paper needs to be continuously transmitted between multiple groups of rollers. The floating roller, as the core component of tension control, maintains the stability of paper tension by adjusting the position and pressure, avoiding problems such as blurred printing patterns, inaccurate overprinting, paper tearing or wrinkling caused by tension fluctuations.

[0003] The printing machine tightness adjusting device with publication number CN221140541U has a certain up and down floating of the tightness adjusting of the tightness roller through the elasticity of the spring, preventing the tightness of the printing paper from changing again after the tightness roller is adjusted, thereby reducing the tightness adjusting frequency. The connecting plate is arranged between the two printing machine support plates and slides along the printing machine support plate. The lug is connected with the tightness roller through the bearing, supporting the tightness roller while not affecting the rotation of the tightness roller, so that the tightness roller can only move longitudinally.

[0004] The printing machine tightness adjusting device adjusts the tension of the transmitted paper by adjusting the lifting of the tightness roller, but the lifting degree of the tightness roller is limited. When the tightness roller is adjusted and the paper is still in a relaxed state, the tension of the paper cannot be adjusted, making the effect unsatisfactory when the paper is greater than the tension. Therefore, improvement is needed. UTILITY MODEL CONTENTS
