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 roller sealing device for preventing back suction. The centerless roller sealing device comprises a rectangular box, a roller sealing mechanism is arranged on the inner side of the rectangular box, and a linkage transmission mechanism is arranged on one side of the rectangular box. The centerless roller sealing device has the beneficial effects that the simple structural design is adopted, the manufacturing cost is reduced, and meanwhile, the sealing effect is improved; and a cylindrical box and a centerless roller are cut together under the action of gravity to form a sealing line surface, airflow in a triangular area is prevented from rising, materials are prevented from being sucked back upwards, the phenomenon that fibers wind a pressing roller or a stripping roller is eradicated, and smooth operation of equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of negative pressure three-roller collection, and more specifically, relates to a centerless roller sealing device for preventing suckback. Background technique [0002] At present, domestic and foreign enterprises mainly adopt the hanging basket sealing method for the anti-suction control of the negative pressure three-roller collection device. The fan-shaped area is sealed to block the airflow formed by negative pressure to prevent falling objects from being sucked back; [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 fail...
