Technical Field

[0001] The utility model relates to the field of paper processing, in particular to a rewinding machine which can be adjusted according to the size of paper. Background Art

[0002] Papermaking generally refers to a production process in which water is used as a fiber carrier, and after pulping and seasoning, the pulp is dehydrated on a filter screen to form wet sheet paper, which is then further squeezed, dehydrated, and dried to form paper. When making paper, a rewinder is needed. A rewinder is a commonly used device in the fields of paper, film, etc. Its purpose is to rewind the paper rolls (called base paper rolls) produced by the papermaking machine in sequence, and the paper is rewound to be made into finished paper for shipment. However, most of the existing rewinders have a simple structure and do not have an adjustment mechanism. They cannot be adjusted according to the size of the paper, which can easily cause paper damage during the rewinding process, reducing the convenience of use. In addition, the paper cannot be flattened while rewinding, which can easily cause wrinkles, affecting the subsequent use effect, and thus easily affecting the convenience of use of the entire rewinder. Utility Model Content
