Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rewinding machines, in particular to a tension control device for a rewinding machine. Background Art
[0002] The 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 paper machine in sequence. After rewinding, the paper is made into finished paper for shipment. It has become a development trend in the papermaking machinery industry to use AC drive instead of DC drive for rewinders. The paper rolls rolled by the rewinder are relatively soft, and may be damaged or broken inside, with uneven edges on both sides and paper width. They cannot be directly used in paper processing or printing machines. Most types of paper (such as newsprint, letterpress printing paper, packaging paper, etc.) must be trimmed, slit, and spliced by the rewinder, and rewound on the paper roll core to form finished paper rolls of certain specifications and certain tightness requirements before they can be shipped.
