Pressure belt type vacuum dewatering device

Abstract

The invention discloses a pressure belt type vacuum dewatering device which comprises a vacuum water absorption device for absorbing fabric moisture and a rotary pressure belt mechanism arranged above the vacuum water absorption device and used for adjusting the fabric water permeability; the vacuum water absorption device is provided with a vacuum suction pipe, water absorption openings are formed in the pipe wall of the vacuum suction pipe from one end to the other end in the axial direction, sealed pistons corresponding to an absorbed fabric in breadth are arranged at the two ends of the vacuum suction pipe, servo drive mechanisms for driving the sealed pistons are arranged outside the vacuum suction pipe, a photoelectric detection device for detecting the breadth of the fabric is arranged on the cloth inlet side of the vacuum suction pipe and is connected with the servo drive mechanisms through control units. According to the pressure belt type vacuum dewatering device disclosed by the invention, the fabric on the vacuum suction pipe is compacted through a pressure belt to keep the proper ventilation volume of the fabric, and the pressure belt type vacuum dewatering device is particularly suitable for knitted plush and blanket type products with strong air permeability; according to a cloth edge distance signal collected by a photoelectric pipe, through the control units and the servo drive mechanisms, the tracking seal of the sealed pistons for the water absorption ports uncovered by the fabric is realized.

Description

technical field [0001] The invention relates to a vacuum dehydration device used in the textile industry, in particular to a belt-pressing vacuum dehydration device. Background technique [0002] At present, the vacuum water absorption equipment in related industries at home and abroad does not have a belt press mechanism, which is more suitable for vacuum water absorption of products with high warp and weft density such as plain cloth, but cannot form effective vacuum water absorption for products with strong air permeability such as knitted plush and blankets. Vacuum area. [0003] At the same time, the vacuum suction pipes in the vacuum suction equipment in the existing textile industry generally adopt negative sealing, that is, the sealing device is installed outside the vacuum suction pipe, and the sealing is completed under the action of vacuum suction; since the sealing device is installed outside the vacuum suction pipe, it cannot The best combination of high vacuum...
