The hydraulic paper shredding mechanism belongs to a partial structure in the hydraulic paper shredder and is also a key structure for shredding paper, and the specific structure, the functional principle and the technical effect of the hydraulic paper shredding mechanism are detailed in the foregoing, so that the details are not repeated herein.

For any technical details regarding the hydra-shredder mechanism, reference may also be made to the above description of the hydra-shredder mechanism.

opening the case 4, and injecting liquid and paper to be cut into the paper shredding container 1 of the hydraulic paper shredding mechanism;

the casing 4 is closed and the cutter assembly 2 is driven to cut the sheets.

Further, in the embodiment of the present invention, when the number of sheets is small, the cutter assembly 2 is driven to move at a high speed to cut the sheets;

when the number of the paper is large, the paper is soaked in the liquid and drives the cutter assembly 2 to cut the paper at a low speed, and after the paper is soaked, the cutter assembly 2 is driven to cut the paper at a high speed.

Therefore, when the hydraulic paper shredder is used for liquid shredding, different shredding modes can be selected according to different paper quantities.

The first mode is for a case where the number of sheets is small, for example, when the number of sheets is within 10. In this mode, when the number of paper sheets is small, the paper sheets can be cut strongly in water directly by the high-speed motion of the cutter assembly 2, so that the paper sheets can be directly shredded into pulp. For example, when the cutter assembly 2 is a rotor cutter, the driving device 5 can be used to drive the rotor cutter to rotate at a high speed, and the cutter blades 22 of the rotor cutter can be used to cut paper at a high speed.

The second mode is for a large number of sheets, for example, when the number of sheets is greater than 10. When the number of the paper is large, the paper can be soaked firstly in the mode, and the paper is cut by matching with the cutting motion of the cutter component 2 at a slow speed, so that the paper is softened firstly in the soaking process, and then the paper can be cut by matching with the cutting motion at a high speed after being completely soaked. For example, when the cutter assembly 2 is a rotor cutter, the driving device 5 may be used to drive the rotor cutter to rotate at a slow speed to soften the paper, and then the rotor cutter is driven to rotate at a high speed to cut the paper at a high speed by the cutter blades 22 of the rotor cutter.
