Description

Film volume unwinding device

(1) technical field

The utility model relates to the Fabricating machinery of diaphragm cylinder material, is specially a kind of film volume unwinding device.

(2) background technology

Plastic sheeting, paper or cloth all will be wound on the film volume that mandrel becomes reel at process of manufacture, and big film coil diameter can reach more than 1 meter.

The film of winding twists in and carries out next step and add man-hour, when for example getting into cutting machine, coating machine, MULTILAYER COMPOSITE equipment, coating apparatus etc., all needs unwinding device that the diaphragm of reeling is launched once more, supplies next process to use.In the process that diaphragm launches, require membrane tension to regulate, the phase center line left and right sides, edge of diaphragm is adjustable.Traditional unwinding device volume core just is placed on the two stands rotationally, the film volume is erected, by the pulling of subsequent processing, emit diaphragm.The rotor inertia of film volume is very big when completely rolling up, and membrane tension is often excessive, unreels that the film coil coil-diameter diminishes gradually in the process, and diaphragm again can be loose, causes the edge to swing, and is difficult to stablely, influences the processing of subsequent processing.Wide cut diaphragm (fabric width is more than three meters) particularly, the centering problem is more outstanding.

(3) utility model content

The purpose of the utility model is a kind of film volume of design unwinding device, disposes oscillating oil cylinder, can realize unreeling diaphragm automatic tracking centering.
