Large package control equipment for coiling organic membrane and method

Abstract

The invention discloses large package equipment for coiling an organic membrane and a method. Coiling angular speed and tension of the organic membrane are controlled by the equipment, so that the coiling package amount of the organic membrane is increased, joint waste of the organic membrane is decreased, the production efficiency is enhanced, influence of coiling process on the organic membrane is reduced, and the labor intensity of workers is reduced. The equipment comprises a furnace body, an uncoiling device and a coiling device, wherein the uncoiling device puts the organic membrane into the furnace body in a way of self correcting angular speed and gradually reduced tension taper, and the coiling device drags the organic membrane out of the furnace body in a way of self correcting angular speed and gradually reduced tension taper. An uncoiling tension detection device comprises a floating roller bearing shaft, a floating roller arranged on one end of the floating roller bearing shaft, a counter weight arranged on the other end of the floating roller bearing shaft, a sensor arranged on the floating roller bearing shaft, a low friction cylinder rotatably connected with the floating roller bearing shaft and a ratio regulating valve used for controlling the low friction cylinder. Drive rollers are all connected with servo motors.

Description

technical field [0001] The invention relates to organic film processing and manufacturing equipment and methods, and belongs to the technical field of organic film processing and manufacturing, in particular to a large volume organic film winding control equipment and method. Background technique [0002] The manufacturing technology of organic film, the current winding technology of organic film mostly adopts the constant line speed and constant tension winding method, the winding control system composed of main speed + floating roller feedback compensation, with the change of the winding diameter during the winding process, When the package volume reaches a certain level, due to the limitation of the feedback value range of the floating roller, the requirement for a large package volume cannot be realized. Because the organic film will expand and shrink during the manufacturing process, the constant line speed and constant tension winding method will cause negative effects...

Problems solved by technology

[0002] The manufacturing technology of organic film, the current winding technology of organic film mostly adopts the constant line speed and constant tension winding method, and the winding control system composed of main speed + floating roller feedback compensation, as the winding diameter changes during the winding process, When the package volume reaches a certain level, the requirement for a large package volume cannot be realized due to the limitation of the feedback value range of the floating roller

Because the organic film will expand and shrink during the manufacturing process, the constant line speed and constant tension winding method will cause negative effects such as normal temperature stretching, loose winding, and uneven winding of the organic film.
