Base material graph-text length control method in compounding process

Abstract

The invention provides a base material graph-text length control method in the compounding process. The method includes the following steps that 1) a theoretical value of a single circulating graph-text length level signal is calculated and obtained according to equipment parameters and a set rotation speed and is recorded as t1, and t1 is input into a computing system; 2) the circulating graph-text length level signal in the moving direction of a base material is collected in real time, and the single circulating graph-text length level signal is recorded as t and input into the computing system; 3) the equivalent relation between t and t1 is compared, and according to a comparison result, stretching or retracting or normality of the base material is obtained; and 4) according to the conclusion in the step 3), the relationship between the speed of a motor and the speed of an uncoiling motor in a coating mechanism and / or a composite mechanism is adjusted, and finally, t is equal to t1.The method is simple in structure, clear in principle and convenient to use. Through conversion and comparison of the level signal and the rotation speed of the motor, rotation of the motor is controlled and adjusted, so that the uncoiling device reaches the most ideal state, base material graph-text deformation is prevented, the product production quality is improved, requirements of industrialproduction are met, and the method is suitable for application and popularization.

Description

technical field [0001] The invention relates to a control method and system, in particular to a method and device for controlling graphics and text of substrates in compounding, and belongs to the field of mechanical technology. Background technique [0002] The application of composite machines is becoming more and more common, and the types of composite substrates are also becoming more and more extensive. Among them, most of the glued composite substrates are printing materials. In the production process of the composite machine, the composite base material needs to pass through a long transfer channel; therefore, for materials with high stretchability, such as PE, NY, etc., if the tension is not selected properly, it is easy to cause excessive deformation of the composite product, resulting in product failure. The quality is not up to standard, and even subsequent processing cannot be carried out. Contents of the invention [0003] In view of the deficiencies in the a...
