A dyeing machine auxiliary agent intelligent distribution system and its control method

Abstract

The invention discloses a dyeing machine auxiliary agent intelligent distribution system and a control method thereof. The system comprises an auxiliary agent storage tank, an auxiliary agent distribution valve, a flushing water valve, a distribution rotor pump, a pipeline reverse forced mixer, a flow meter, a Material valve, dyeing machine material vat and control system. The control system includes upper computer intelligent PC system, PLC control system, compressed air barometer, frequency converter and on-site signal collector. The upper computer intelligent PC system obtains the name, dosage and drop The material valve number forms the auxiliary agent distribution order; according to the current auxiliary agent distribution data, the recommended pre-stop value is obtained, and the empirical pre-stop value is superimposed according to a variable ratio to obtain the final pre-stop value. The PLC control system collects the distribution parameters and judges according to the final pre-stop value The remaining distribution volume controls the opening and closing of the auxiliary distribution valve, blanking valve, distribution rotor pump and flushing water valve, and adjusts the output frequency of the inverter. The invention automatically adjusts the pre-stop value according to the historical distribution data, thereby improving the distribution accuracy.

Description

technical field [0001] The invention relates to the technical field of material and reagent distribution, in particular to an intelligent distribution system and control method for dyeing machine auxiliaries. Background technique [0002] During the distribution process of dyeing machine auxiliaries, various factors such as the viscosity and fluidity of different auxiliaries, the length of distribution pipelines at different discharge ports, the operating frequency of distribution pumps, the pressure of compressed air, and the distribution volume will all cause After the dispensing valve is closed, the volume of the additive flowing through the valve is different, and these factors comprehensively affect the dispensing accuracy of the additive. At present, the accuracy control of auxiliary agent distribution requires technicians to conduct distribution tests many times, record the error between the order delivery value and the actual delivery value, and then adjust the accur...

Problems solved by technology

Since the measurement of the flowmeter requires the ion of the solution to be relatively uniform to measure accurately, the mixture of these uneven additives and water flowing through the flowmeter will cause the flowmeter to jump violently, resulting in a large measurement error and affecting the measurement of flushing water.

On the other hand, when the same dyeing machine needs multiple auxiliaries, during the conversion process of dispensing one auxiliary and then dispensing the second auxiliaries, due to the large difference in specific gravity, diffusion capacity and conductivity of different auxiliaries , the mixing aid flowing through the flowmeter will be very uneven, which will also cause the measurement value of the flowmeter to fluctuate violently, and the measurement error will be large
