[0006] A pulping device for producing pulp molded products, comprising a pulping box, the pulping box is fixed on a support frame, a pulping barrel is rotatably arranged inside the pulping box, a crushing motor is vertically arranged downward on the top of the pulping box, a crushing rod is fixedly connected to the rotor of the crushing motor, a plurality of crushing blades are fixed on the crushing rod, and a plurality of first crushing teeth are evenly distributed on the crushing blades;

[0007] A plurality of filtering holes are evenly arranged on the barrel wall of the pulping barrel, and a discharge pipe is arranged at the bottom of the pulping box.

[0008] As an improvement: a plurality of second crushing teeth are provided on the inner wall of the pulping barrel.

[0009] As an improvement: an annular limiting groove is provided on the top inner wall of the pulp box, and the top of the pulp barrel is rotationally limited inside the annular limiting groove.

[0010] As an improvement: a feed funnel and a water injection pipe are provided on the top of the pulping box, and the feed funnel and the water injection pipe are both located above the pulping barrel.

[0011] As an improvement: an electric valve is provided on the discharge pipe.

[0012] As an improvement: a rotating motor is provided at the bottom of the pulping box, and the rotor of the rotating motor is fixedly connected to the bottom of the pulping barrel.

[0013] As an improvement, a liquid level sensor is provided at the bottom of the pulp box.

[0014] In summary, the utility model has the following beneficial effects:

[0015] 1. The crushing motor drives the crushing rod, the crushing blades and the first crushing teeth to rotate, and the waste paper can be crushed. At the same time, the pulping barrel rotates. Under the action of centrifugal force, the waste paper is fully mixed with water to form slurry after crushing. The slurry is discharged into the pulping box through the filter hole and discharged through the discharge pipe. At this time, the slurry discharged through the discharge pipe is a finished product and does not need to be filtered twice, thereby improving the pulping efficiency;

[0016] 2. A number of second crushing teeth are arranged on the inner wall of the pulping barrel, and the rotation of the pulping barrel can also crush the waste paper, thereby improving the crushing efficiency to a certain extent;

[0017] 3. The annular limit groove can improve the rotation stability of the pulping barrel. BRIEF DESCRIPTION OF THE DRAWINGS
