Description

Technical Field

[0001] The utility model relates to a material arch breaking and screening device, belonging to the technical field of material quantitative conveying. Background Art

[0002] The rubbing screen machine mainly consists of a frame, explosion-proof motor, reducer, gear, transmission shaft, driven shaft, rotating impeller, screen, tank, etc. When the material enters the rubbing screen machine, the motor drives the rotating impeller on the transmission shaft and driven shaft, causing the material on the screen surface to flip and squeeze, and the material is discharged into the hopper through the screen. In order to meet the process requirements of different propellants during water-discharging and feeding, the gears are driven by adjusting the speed of the motor and reducer to achieve quantitative discharge.

[0003] The existing rubbing and screening machines have the following disadvantages when rubbing and screening materials. During the rubbing and screening process, due to the inconsistent moisture content of the cotton materials of different grades of absorbent drugs, the rubbing and screening materials will be arched and suspended, resulting in loose materials. Personnel are required to enter dangerous workplaces many times to use limited tooling for processing, which poses a great safety risk. Utility Model Content

[0004] The utility model aims to solve the problem of safety risks when the existing rubbing and screening machines rub and screen materials, and to provide a material arch breaking and rubbing and screening device.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] The utility model discloses a material arch breaking and rubbing screen device, comprising a frame, a rotating motor fixed to the right side of the upper end of the frame, a rubbing screen box fixed to the left side of the frame, a screen arranged at the lower end of the inner cavity of the rubbing screen box, an active rubbing screen shaft and a driven rubbing screen shaft horizontally arranged at the lower part of the inner cavity of the rubbing screen box, a stirring shaft horizontally arranged at the upper part of the inner cavity of the rubbing screen box, and a feed hopper fixed above the rubbing screen box; the output shaft of the rotating motor is connected to the active rubbing screen shaft through a reducer and a coupling, so that the rotating motor controls the active rubbing screen shaft to rotate, and the active rubbing screen shaft, the driven rubbing screen shaft and the stirring shaft are connected through a gear transmission mechanism, so that the active rubbing screen shaft, the driven rubbing screen shaft and the stirring shaft rotate synchronously;

[0007] The active rubbing screen shaft and the driven rubbing screen shaft are respectively provided with rubbing screen impellers;

[0008] The stirring shaft is provided with stirring blades.

[0009] The rotating motor adopts an explosion-proof motor.

[0010] The active rubbing screen shaft, the driven rubbing screen shaft and the stirring shaft are respectively connected to the rubbing screen box through rotating bearings.

[0011] Working process

[0012] When the material is sifted, the material to be sifted is first transferred to the feed hopper above the sifting box. When the material enters the sifting box, the rotating motor is started. The rotating motor drives the active sifting shaft to rotate through the reducer and the coupling. The driven sifting shaft and the stirring shaft rotate synchronously under the action of the gear transmission mechanism. The active sifting shaft and the driven sifting shaft sift the material through the sifting impeller on the side wall to squeeze the material through the screen. The stirring shaft stirs the material above the inner cavity of the sifting box through the stirring blades on the side wall to prevent the material from arching up and avoiding the material from being fluffy.

[0013] Beneficial effects:

[0014] The utility model discloses a material arch breaking and rubbing screen device. The rubbing screen driven shaft drives the stirring shaft to rotate, which can provide power for the stirring device. The upper and lower parts work simultaneously to realize full stirring of the material, prevent the material from arching up and being suspended in the air, reduce the possibility of material bursting, and improve the safety of employees during operation.
