Description

Technical Field

[0001] The invention belongs to the technical field of packaging equipment and relates to a thermal paper roll conveying device. Background Art

[0002] With the rapid development of the express delivery industry, the demand for thermal paper used as the base material for label production is growing rapidly.

[0003] During the preparation of thermal paper, the coated thermal paper roll is easily discolored by external influences such as impact, light, and high temperature. Therefore, if a traditional paper roll conveying system is used to convey the coated thermal paper, it has the following shortcomings: 1. The contact surface of existing conventional conveying equipment is made of steel. During the conveying process, due to the polygonal effect, the chain plate and the paper roll will rub against each other, causing the thermal paper roll to change color; 2. When a conventional paper kicker transfers thermal paper rolls, the contact area between the paper kicking arm and the thermal paper roll causes discoloration; 3. The uneven surface of the paper ramp causes the paper roll to change color; 4. The paper roll is transferred by turning and rolling. Summary of the Invention
