Embodiment Construction

[0022] The invention is a control system capable of realizing high-precision and large-scale automatic batching and weighing, and establishes a dynamic ratio model for the differences in dye specific gravity, particle size, flow rate and drop size of various dyes. On the basis of solving the dynamic weighing accuracy, the network real-time multi-task control technology is applied to form a dynamic weighing and automatic batching production line of 20-100 kinds of materials. Using adaptive control algorithm, according to the specific gravity and particle size of various dyes, the corresponding final drop control time is established, and according to the real-time closed-loop feedback of high-precision scales, accurate weighing is finally realized. The weighing range of each dye is between 0.1g-32kg, the minimum resolution is between 0.01-0.1g, and the weighing accuracy is ≤1%. The system is equipped with a sample debugging system and a production system, both of which can compl...

Abstract

This invention, relating to automatic measure technology realm, discloses a control system for automatic batch weighing powdered solid dye in textile dyeing and finishing industry, which is composed by an upper machine, a lower machine and a high-precision electronic scale, also defines as high-precision and automatic batching and dyeing control apparatus adopting modern automatic control technology to make the batching course supermatic. Wherein, the lower machine comprises multi-axis motion control card and electric control cabinet; the upper machine is linked to multi-axis motion control card via PCI bus, and forms a closed-loop feedback system with said scale; upper machine and the scale are separately connected to A.C. regulated power supply. The system adopts advanced control means based on machine learning, optimality principle, adaptive control theory and computer net technology to solve problem of precision in batching and dynamic weighing powder dye.

Description

technical field [0001] The invention relates to the technical field of automatic measurement, in particular to a high-precision automatic batching and weighing control system for powdery solid dyes in the textile dyeing and finishing industry. Background technique [0002] The domestic textile dyeing and finishing industry has long used manual weighing methods for batching due to the inability to overcome the problem of controlling the accuracy of automatic weighing. The low batching accuracy is difficult to guarantee product quality. The realization of batching automation has been investing a lot of energy and material research for major companies at home and abroad to form a large number of products, such as grain weighing and packaging production lines, petrochemical weighing and batching production lines, etc., and the above are all for relatively constant or similar ratios and relative weighing. It is not very small. For the printing and dyeing industry, 20 to 100 kinds...
