Tipping Paper Rewinder Based on Servo System

Abstract

The invention discloses a tipping paper rewinding machine on the basis of a servo system. The tipping paper rewinding machine is characterized in that a linear speed is measured by a speed measuring roll in a tipping paper take-up procedure, real-time disc diameters of an unwinding disc and a winding disc are computed according to the real-time linear speed, a rotational speed of an unwinding motor and a rotational speed of a winding motor, and then the rotational speed of the unwinding motor and the rotational speed of the winding motor are computed according to the obtained disc diameters and a linear speed, which is given by a machine, in the tipping paper take-up procedure, and are adjusted via a central processing unit. The tipping paper rewinding machine has the advantages that circular adjustment is realized, so that the linear speed in a procedure for rolling tipping paper on the rewinding machine is consistent with the given speed, tension on the surface of the tipping paper in the take-up procedure keeps constant, disc surfaces are flat, and the winding quality is improved.

Description

technical field [0001] The invention relates to a tipping paper rewinding machine based on a servo system. Background technique [0002] Rewinding machine is a special equipment for papermaking. Its purpose is to rewind the paper rolls produced by the paper machine (usually called base paper rolls, tipping paper in this invention) in sequence, and the paper is made into finished products after rewinding. Paper leaves the factory. At present, it has become a development trend in the papermaking machinery industry to use AC drives instead of DC drives for rewinders. 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 edge trimming, slitting, jointing, and rewinding on the paper roll co...

AI Technical Summary

Problems solved by technology

The current tipping paper rewinding machine has the following defects: the surface tension of the base paper roll is small, and it will relax and wrinkle during winding, and it will deviate in the lateral direction and be uneven; the surface tension of the base paper roll is large, and the paper is easily deformed or broken when it is stretched Paper
