Description

Technical Field

[0001] The utility model belongs to the field of waste paper pulping machines, and in particular relates to a waste paper pulping machine for pulp molding production. Background Art

[0002] In the field of paper product processing, using waste paper to make pulp can reduce the felling of wood, which is beneficial to ecological balance and environmental protection, and can also reduce production costs. In the process of making waste paper pulp, a pulping machine is needed.

[0003] The Chinese patent with publication number CN219862103U discloses a waste paper pulping machine for pulp molding production, including a tank body, a feed hopper is installed on the top of the side of the tank body, a controller is installed in the middle of the side of the tank body, a motor is installed on the top of the tank body, a rotating shaft is installed on the output shaft of the motor, a plurality of stirring blades distributed equidistantly are installed on the outer wall of the rotating shaft, a scraping assembly is formed between the stirring blades and the tank body, a partition is installed in the inner cavity of the tank body below the rotating shaft, a filter plate is detachably provided below the partition, and a filter plate is provided at the bottom of the tank body. The utility model is provided with a discharge port. The waste paper pulp can be stirred by the coordinated use of a motor, a rotating shaft and a stirring blade.
