This invention discloses a self-cleaning dust filtration mechanism for cardboard processing, relating to the field of dust filtration technology in cardboard processing. It includes an adjustment unit mounted on top of a fixed frame to prevent dust overflow, and a cleaning unit that works in conjunction with the adjustment unit to periodically clean the dust inside the dust collection hopper. The top of the fixed frame is equipped with elastic ropes whose thickness changes with pulses. The dust collection hopper contains a first dust collection plate and a second dust collection plate for collecting dust. This invention utilizes a fixed rod at the top of the lifting frame that engages with the inclined groove of a rotating ring to convert displacement along the inclined groove into circumferential rotation of the rotating ring. As the rotating ring deflects, the elastic ropes are simultaneously tightened, dynamically increasing the gap between adjacent elastic ropes and providing a smooth falling channel for dust. Furthermore, the first and second dust collection plates flip from a horizontal to a vertical state, causing dust adhering to their surfaces to fall into the bottom of the dust collection hopper and be collected by an external collection system.

The application discloses a rotating shaft assembly and a clothes processing device. The rotating shaft assembly comprises a first rotating shaft, a second rotating shaft and a spring piece. The first rotating shaft is connected with a machine body, the second rotating shaft is connected with a door body, the second rotating shaft is located on one side of the first rotating shaft in the axial direction and coaxially arranged with the first rotating shaft, and the first rotating shaft is rotationally connected with the second rotating shaft. The spring piece is sleeved on the first rotating shaft and the second rotating shaft, one end of the spring piece is connected with the first rotating shaft, and the other end of the spring piece is connected with the second rotating shaft. The first rotating shaft and the second rotating shaft are arranged along the axial direction of the rotating shaft assembly, and the spring piece is sleeved on the first rotating shaft and the second rotating shaft. The spring piece has a longer axial length, the force acting on the spring piece can be transmitted to a farther position away from the connecting position of the spring piece and the first rotating shaft / second rotating shaft, the deformation of a single coil of the spring piece is smaller, the service life of the spring piece can be prolonged, and the spring piece can be prevented from being frequently in a high-strength deformation state and thus prematurely failing.
