Circuit system for automatic material weighing and blending production line control

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...

[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 ensure 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 of dyeing materials are needed for dyeing fabrics, and the various proportions are different. It often appears that only a few grams or more than ten grams of materials are required in the formula of a certain fabric and requires There is nothing you can do if the weighing accuracy cannot be lower than 1%.
