Pressure control system of evenness padder

Abstract

The invention provides a pressure control system of an evenness padder. The system includes an air-channel pneumatic proportional valve, an ail-controlled oil-channel pneumatic proportional valve and an oil-channel oil pressure detector, wherein the air-channel pneumatic proportional valve is arranged on an air channel of the pressure control system of the evenness padder and used for controlling input of air pressure and detecting the air pressure, the ail-controlled oil-channel pneumatic proportional valve is arranged on an air-controlled oil channel of the pressure control system of the evenness padder and used for controlling input of oil pressure, and the oil-channel oil pressure detector is arranged on the oil channel of the pressure control system of the evenness padder and used for detecting the oil pressure value; the air-channel pneumatic proportional valve, the ail-controlled oil-channel pneumatic proportional valve and the oil-channel oil pressure detector are connected with a controller; according to different fabric parameters and the rotation speed of a roller, the controller calculates the air pressure value meeting the requirement of the liquid carry rate, according to a compatibility model, the corresponding oil pressure value is then calculated, and then the open degree of the air-channel pneumatic proportional valve and the open degree of the ail-controlled oil-channel pneumatic proportional valve are adjusted. According to the system, the liquid carry rate of the evenness padder and the rolling liquid uniformity can be accurately controlled, the principle of the system is simple, the structure is compact, the cost is low, the reliability is high, the stability is high, and operation and maintenance are convenient to conduct.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a uniform rolling car pressure control system. Background technique [0002] The uniform padder is widely used in the fabric processing and production process. It relies on the extrusion of two rolls to remove excess dye liquor in the process of fabric dyeing and sizing, or to make the surface of the fabric smooth and clean to meet certain requirements. For fabrics that have been uniformly rolled by a padder, the rolling ratio and the uniformity of the rolling liquid are the two most important evaluation indicators: too high or too low a rolling ratio will increase the burden on subsequent processing or be unfavorable for subsequent production; The uneven liquid extrusion in the width direction will also cause chromatic aberration. [0003] Traditional uniform rolling cars are mostly controlled mechanically, relying on manual knobs to adjust the ratio of air pressure t...

Problems solved by technology

This control and adjustment method often cannot meet the precise input of air pressure and oil pressure, resulting in the deviation of the rolling ratio and rolling fluid uniformity often exceeding the allowable range
