Description

Technical Field

[0001] The invention relates to the field of rewinding devices, and in particular to a tape slitting and rewinding device. Background Art

[0002] Rewinder is a special equipment for paper, mica tape and film. Its purpose is to rewind the paper rolls (called base paper rolls) produced by the papermaking machine in sequence. After rewinding, the paper is made into finished paper and shipped out. Rewinder is generally used for rewinding, slitting and splitting mica tapes, paper and films. It is often used to slit wide rolls and plays an important role in subsequent re-slitting. It is a special equipment for paper, mica tape, film and tape.

[0003] During the rewinding process of the rewinding machine, wrinkles are inevitable due to the elasticity of the tape. The appearance of wrinkles will reduce the usability of the tape and reduce the qualified rate of the product. In the prior art, if wrinkles appear during the rewinding process, they are often sorted manually, which greatly reduces the production efficiency of the product.

[0004] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention
