Description

Double-shaft rewinding and disc separating machine

Technical Field

The utility model belongs to the technical field of the papermaking, especially, relate to a biax rewinding machine of dividing dish.

Background

In the current society developing at a high speed, the demand of functional crepe paper is increasing day by day, and in order to facilitate subsequent processing, semi-finished products are mostly realized in a dish-packing manner. The PMT4 paper machine of our company mainly produces crepe paper, the paper of this type has the characteristics of large elongation, fluffy softness and the like, the thickness and the elongation of the base paper are required to be kept as much as possible in the slitting and rewinding process, and the diameter of a general disc is required to be about 900 mm. When the ordinary rewinding splitting machine splits the paper, the phenomenon of edge lapping is easy to occur due to poor paper stiffness, so that the split bobbin paper cannot be split, waste products are produced, and the production yield is influenced. The existing tray separator on the market achieves the tray separating effect, but the fly roll adopts a swing arm form, and the fly roll moves in an arc track. In the winding process, the paper pressing roller position is increased along with the increase of the diameter of the paper winding disc, so that deviation gradually occurs between the paper pressing roller position and the center position of the paper winding disc, paper guiding tension changes, the tightness of the paper winding disc is inconsistent due to the change of the tension, the disc surface is not good, and the diameter of the paper winding disc is limited.
