Automatic taking-up and roll changing device

Abstract

An automatic taking-up reel alternation device comprises a machine frame, a double-station taking-up mechanism and an automatic roll changing mechanism, wherein the automatic roll changing mechanism comprises a cutter mechanism and an automatic roll feeding mechanism, and the automatic roll feeding mechanism comprises an arc-shaped roll feeding mechanism and a press roller. The cutter mechanism and the press roller are arranged on the machine frame. The press roller abuts against and is pressed on a taking-up shaft of a taking-up station through an elastic part. The automatic roll feeding mechanism is arranged on the machine frame at at-leaset one end of the double-station taking-up mechanism, the cutter mechanism and the arc-shaped roll feeding mechanism are located outside the double-station taking-up mechanism and are respectively located on two sides of a sheet on the double-station taking-up mechanism. The arc-shaped roll feeding mechanism and the taking-up shaft of the taking-up station are matched in a fitting or separated mode. When the arc-shaped roll feeding mechanism is fit with the taking-up shaft of the taking-up station, the opening of the arc-shaped roll feeding mechanism corresponds to the press roller, the leading-in end of the arc-shaped roll feeding mechanism is in contact with the sheet passing through the leading-in end, and a shear space is formed between the leading-in end of the arc-shaped roll feeding mechanism and the taking-up shaft of the taking-up station. The cutter mechanism extends into and retreats out of the shear space.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and more specifically, the invention relates to an automatic winding and changing device. Background technique [0002] During the production or processing of sheets (such as films, etc.), the produced or processed sheets are generally wound by a winding device. The traditional winding device generally has only one winding shaft. When the diameter of the sheet taken by the winding shaft reaches the set value and the roll needs to be changed, the machine must be stopped, and then the worker manually removes the finished roll and installs a new one. Take up the reel to facilitate the continuation of the rewinding. [0003] Because the traditional winding device needs to stop when changing the roll, which affects the continuous production or processing, so in order to solve the problem between the stop of the traditional winding device and the continuous production or processing, peo...

AI Technical Summary

Problems solved by technology

However, the reliability of winding by electrostatic adsorption is relatively poor, and sometimes the rewinding shaft cannot absorb the sheet, and, due to the instantaneous high-voltage discharge of static electricity, there is a potential risk of electric shock. Volume is not safe to use
