Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco machinery and relates to an improved YJ17 vortex fan, in particular to a self-cleaning YJ17 cigarette making machine vortex fan. Background Art

[0002] The YJ17 cigarette making machine is a machine specially designed for producing cigarettes. In the YJ17 cigarette making machine, the rolled cigarette rods are cut into double-length cigarettes by the cutting system, and the cigarette conveying system sucks the cigarettes and conveys them to the YJ27 cigarette receiving drum. In the cigarette conveying mechanism, the cigarette conveying relies on the negative pressure generated by the vortex fan to absorb the cigarettes under the conveying suction claws. During the cigarette production process, some dust will enter the vortex fan through the suction channel.

[0003] The vortex fan is composed of a shell, an impeller, and a motor, which is fixed to the studs by four M8 bolts. The stud mounting plate is suspended on the rear frame of the bed conveying mechanism. Part of the dust entering the vortex fan enters the central dust removal system through the pipe along with the high-speed rotating impeller, and part of the wind accumulates in the cavity at the root of the impeller or adheres to the surface of the impeller. As the running time increases, the dust in the impeller cavity will increase, causing the negative pressure of the vortex fan to drop. As a result, during the process of conveying cigarettes, the negative pressure in the suction claws of the conveying mechanism is not enough to absorb the air, and the cigarettes cannot be stably adsorbed on the surface of the suction claws. During the conveying process, cigarettes fall off and are not arranged evenly. Summary of the invention
