Belt-type vacuum dehydration device

Abstract

A belt-pressing vacuum dehydration device, comprising a vacuum suction device for sucking moisture in fabrics and a rotary belt press mechanism arranged above the vacuum suction device to adjust the water permeability of the fabric; The suction port is arranged axially on the pipe wall of the vacuum suction pipe. The two ends of the vacuum suction pipe are provided with sealing pistons corresponding to the width of the fabric to be adsorbed. The outside of the vacuum suction pipe is equipped with a servo drive mechanism for driving the sealing piston. A photoelectric detection device for detecting the width of the fabric is provided on the cloth side, and the photoelectric detection device is connected with the servo drive mechanism through the control unit. The present invention compacts the fabric on the vacuum suction tube through the pressure belt to maintain the appropriate air permeability of the fabric, and is especially suitable for products with strong air permeability such as knitted plush and blankets; The servo drive mechanism realizes the tracking and sealing of the sealing piston to the water suction port on the vacuum suction tube which is not covered by fabric.

Problems solved by technology

[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 installation of the belt pressing mechanism cannot achieve the best combination of high vacuum and flow

Therefore, the traditional vacuum water absorption equipment has poor suction effect, high excess rate (liquid-carrying rate), high energy consumption, and small application range.
