Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of the water baffle door of a cleaning machine, and in particular to a novel rotating door device for a cleaning machine. BACKGROUND

[0002] At present, in order to avoid water splashing out, a water baffle door is generally installed in a cleaning machine, and the existing water baffle door structure generally adopts a hoisting door. The gravity of the hoisting door needs to be supported from above for a long time, and after a long time, the phenomenon of sagging and deformation occurs, so that the door body cannot run smoothly.

[0003] Therefore, it is urgent to develop a door body structure which is simple in structure and smooth in operation. CONTENT OF THE UTILITY MODEL

[0004] The present application aims to provide a novel rotating door device for a cleaning machine to solve the problems in the background art.

[0005] To achieve the above-mentioned purpose, the present application provides a novel rotating door device for a cleaning machine, which adopts the following technical scheme:

[0006] A novel rotating door device for a cleaning machine comprises a rack, and a double-opening door mechanism is arranged on the front side of the rack. The double-opening door mechanism comprises door body assemblies which are symmetrically arranged on both sides of the rack. The door body assembly comprises a door plate, a rotating shaft, a lower bearing seat, an upper bearing seat, an air cylinder, a linear guide rail, a rack gear and a pinion gear. The lower bearing seat and the upper bearing seat are fixed on the rack correspondingly. The rotating shaft is vertically installed in the lower bearing seat and the upper bearing seat. The door plate is arranged between the lower bearing seat and the upper bearing seat and is fixed on the rotating shaft. The pinion gear is fixed on the top end of the rotating shaft. The linear guide rail is fixed on the rack. The rack gear is slidingly connected to the linear guide rail. The air cylinder is fixed on the linear guide rail and is used to drive the rack gear to move. The rack gear is engaged with the pinion gear.

[0007] Preferably, in order to improve the water blocking effect, rubber pads are wrapped on the opposite side walls of the two door plates.

[0008] A connecting piece is fixed on the door plate near the positions close to both ends. The connecting piece comprises a base block which is welded on the door plate. A lock block is fixed on the base block by means of screws. Arc-shaped grooves are formed on the surfaces of the lock block and the base block.

[0009] Preferably, in order to improve the mounting firmness of the door plate, anti-skid lines are formed on the surface of the rotating shaft corresponding to the positions of the connecting pieces.

[0010] In summary, the application includes at least one of the following beneficial technical effects: the new rotary door device for the cleaning machine has simple structure, good opening and closing effect, adopts the split door mode, and utilizes rack and pinion drive, which is reliable in transmission and stable in operation. The rack, pinion and cylinder are arranged on the top of the rack, which does not rust and corrode and does not occupy the space inside the rack, and the maintenance is also relatively simple.
