Description

Technical Field

[0001] The utility model belongs to the technical field of chemical fiber paper tube production, and in particular relates to a paper stretching control device in a chemical fiber paper tube production process. Background Art

[0002] During the production process of chemical fiber paper tubes, the rolled paper needs to be unwound, then transported through various traction rollers and guide rollers, coated with glue, compounded to form multiple layers of paper, and then wound to form a paper tube. Finally, cutting, chamfering and other operations are performed to obtain chemical fiber paper tubes. When the paper is unrolled and pulled, the surface of the paper is relatively smooth, and the contact between the paper and the roller is prone to slippage, resulting in speed errors when the paper is transported between different sections between the unwinding roller and the traction roller, which in turn causes the paper to be pulled excessively or too loose. Problems such as paper breaking are prone to occur, and the paper tension is unstable. The compounded multiple layers of paper and even the subsequent paper tubes are prone to bursting.
