Abstract

The invention discloses a papermaking rewinder with upper and lower dust removal. The dust removal device includes an upper dust collecting box, a lower lifting central column and a pair of lower closing plates; Guide groove; the lifting of the lower lifting center column is set in a pair of lifting guide grooves and vertical limit units are formed at the left and right ends; a pair of lower closing plates are arranged in the lower dust outlet groove and the far ends are respectively hinged on the bottom of the lower dust outlet groove Between the left and right side walls; the left and right parts of the lower lifting center column are respectively rotated with an outer insertion connection block and an inner insertion connection block; a pair of inner insertion connection blocks are formed on the rear end surface of the lower closed plate on the front side Block matching connecting groove; the front end surface of the lower closed plate on the rear side is formed with a pair of connecting grooves matching with the externally inserted connecting block.

Description

technical field [0001] The invention relates to the field of papermaking machinery, in particular to a papermaking rewinder for upper and lower dust removal. Background technique [0002] The rewinding machine is a special equipment for papermaking. Its purpose is to rewind the paper rolls produced by the paper machine in sequence, and the paper is made into finished paper after rewinding. The paper roll rolled by the winder is relatively soft, the inside may be damaged or broken, the edges on both sides are not neat, and the width of the paper width cannot be directly used in paper processing or printing machines. Most paper types (such as newsprint , Toppan printing paper, wrapping paper, etc.) must go through rewinding machine trimming, slitting, jointing, and rewinding on the paper roll core to form a finished paper roll with a certain specification and a certain tightness requirement before leaving the factory. During the rewinding process, a large amount of base paper...
