Problems solved by technology

[0003] However, the design structure is relatively complicated, and the production cost is high. Long-term dust accumulation will easily lead to the imbalance of the hanging basket, and it is inconvenient to clean and maintain; especially in the wool and linen textile industry, due to the characteristics of fibers rich in oil and colloid, and even accompanied by electrostatic effects, The traditional control method is very prone to failure, which will cause the sucking back phenomenon of the falling material, or even wrap the pressing roller or the stripping roller, which will cause the bad result of the deformation and scrapping of the cylindrical box in severe cases.

Abstract

The invention discloses a centerless drum sealing device for preventing back suction. The beneficial effect of the invention is that the simple structure design is adopted, the manufacturing cost is reduced, and the sealing effect is improved; the cylindrical box and the centerless roller are co-cut to form a sealing line surface under the action of gravity, which prevents the air flow in the triangular area from rising, and prevents the rabbit material from rising upward. Suction back, prevent the occurrence of the phenomenon of fiber winding on the pinch roller or stripping roller, and ensure the smooth operation of the equipment.

Description

technical field [0001] The invention relates to the technical field of negative pressure three-roller collection, and more particularly, to a centerless roller sealing device for preventing back suction. Background technique [0002] At present, the anti-suction control of the negative pressure three-roller collection device by domestic and foreign enterprises mainly adopts the hanging blue sealing method. The fan-shaped area is sealed to block the airflow formed by the negative pressure, so as to prevent the falling objects from being sucked back; [0003] However, the design structure is relatively complex, the production cost is high, the long-term dust accumulation easily leads to the unbalance of the hanging basket, and the cleaning and maintenance are inconvenient; especially in the wool and linen textile industry, because the fibers are rich in grease, colloid and other characteristics, and even accompanied by electrostatic effects, The traditional control method is ...
