Abstract

The invention discloses an automatic paper tube expansion method in the field of composite material preparation, which comprises the following steps: S1, a main shaft is mounted on a winding device and is driven by a motor or a brake device, at least two support frames are mounted on the main shaft, a paper tube is mounted on the support frames, the support frames at two ends of the paper tube are provided with flanges, and the flanges are connected with the winding device; the support frame is fixed on the belt main shaft through a fastening screw; s2, the supporting frame is of a cylindrical structure, a polygonal special-shaped groove and a circular groove are formed in the middle of the supporting frame, a synchronous ring is installed on a circular groove shaft, n open type long grooves are formed in the synchronous ring, H-shaped supporting columns are installed in the open type long grooves in the synchronous ring, and the diameter of the circular groove formed in the middle of each supporting column is the same as the width of the open type long grooves of the synchronous ring. And the self weight of the large-diameter air swelling shaft can be reduced to a manual carrying state, so that the large-diameter air swelling shaft is wide in application range and easy to process and manufacture.

Description

technical field [0001] The invention relates to the field of composite material preparation, in particular to a method for automatically expanding and tightening a paper tube. Background technique [0002] During the preparation of composite materials (prepregs), it is necessary to unwind the release paper or rewind the prepregs. Both the release paper and the prepreg are collected or unrolled by means of curling, and the release paper and the prepreg are curled on a 12-inch / 10-inch / 6-inch / 3-inch paper tube. The paper tube is fixed on the rewinding device of the equipment. Due to the diversification of product sizes, the demand for paper tubes is also increasing. In order to ensure that the rewinding and unwinding equipment can meet various paper tubes, it is necessary to prepare air shafts of various sizes and specifications. [0003] At present, 12-inch / 10-inch / 6-inch / 3-inch air shafts are used for winding work in the equipment. When the paper tube is installed at the des...
