Tape casting machine varied-ratio self-adapting controlling system

Abstract

The invention relates to a tape casting machine varied-ratio self-adapting controlling system. The system comprises an extruding part, a casting part, a drawing part, a rolling part, and four electrical controlling parts. The four electrical controlling parts are connected to a bus CC-LINK. The electrical controlling parts are provided with a self-adapting controlling system comprising a frequency converter which is connected to a sensor system. The sensor system comprises four sensor sets which are respectively connected to the extruding part, the casting part, the drawing part, the rolling part, and the frequency converter. The tape casting machine controlling system also comprises a host computer connected to the bus CC-LINK. With the technical scheme provided by the invention, the tape casting machine controlling system can automatically reply both internal changes of the machine and external disturbances, such that the tape casting machine is provided with advantages such as stable performance, high reliability, high automaticity, and energy-saving equipment operation.

Description

technical field [0001] The invention relates to a control system of a tape casting device, in particular to a control system of a tape casting machine. Background technique [0002] As early as the 1950s, composite plastic film packaging materials have come out, and since then the traditional packaging using a single packaging material has entered a new stage of modern packaging. At present, in addition to being widely used in food, medicine and hygienic material industries, it can be found in almost all industrial fields. my country has introduced foreign casting machines since the mid-1980s to start the production of casting plastic films, but most of them are single-layer structure equipment. [0003] The tape casting machine is a special production equipment that uses the casting method to form plastic films. The tape casting control system is the core of the entire tape casting production line and plays a key role in the molding of plastic films. In the 21st century,...

[0004] However, the existing machines are basically lacking in control. Feedback control is usually used in machine control, and feedback control has a certain ability to suppress changes in the machine itself or external disturbances, while the internal parameters of the machine are often Fixed, this will greatly reduce the performance of the machine, and even damage the machine itself
