Slitting rewinder

Abstract

Disclosed is a slitting rewinder. The slitting rewinder comprises a rack; a paper material frame, a paper material tensioning mechanism, a rewinding station, a paper tube cutting station and a conveying mechanism are disposed on the rack; the paper tube cutting station is located above the rewinding station; a paper tube to be slit is connected to a central spindle in a sleeving mode; the central spindle is erected on the rack and on a supporting part and the ends of the central spindle are exposed; the conveying mechanism is provided with a pair of movable supporting blocks; each movable supporting block is provided with one driving mechanism; the movable supporting blocks are wedge blocks, and stop blocks are disposed in the lowest positions of the movable supporting blocks; the highest travel position and the lowest travel position of the movable supporting blocks are disposed on a driving guide way; when the movable supporting blocks reach the highest travel position, the movable supporting blocks lift the central spindle to leave from the supporting part and the central spindle reaches the lowest point along the wedge-shaped surface; when the movable supporting blocks reach the lowest travel position, the central spindle is separated from the movable supporting blocks to reach a driving roller of the rewinding station; the movable supporting blocks reciprocate between the highest travel position and the lowest travel position. The slitting rewinder has the advantage that only one machine is needed to achieve paper tube slitting and finished paper winding.

Description

technical field [0001] The invention relates to a slitting and rewinding machine. technical background [0002] The rewinding machine 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, and the paper is made into finished paper after rewinding. factory. [0003] For the finished paper tube with a paper core, at present, the paper tube is first wound into a paper tube with a paper tube machine, and then the paper tube is cut according to the designed length, and the cut paper tube is removed. Then put the cut paper tube on the mandrel of the rewinder, and glue the paper head to be wound on the paper tube for rewinding. At present, two machines are needed to realize the cutting of the paper tube and the rewinding of the paper product. The unloading and handling of the paper roll after cutting, and the loading of the paper roll into the rewinder all require manual p...

AI Technical Summary

Problems solved by technology

At present, two machines are needed to realize the cutting of the paper tube and the rewinding of the paper product. The unloading and handling of the paper roll after cutting, and the loading of the paper roll into the rewinder all require manual participation, and the degree of automation is low, resulting in low efficiency
