Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a pulping screening device for producing pulp molded products. Background Art

[0002] Pulp molding is a three-dimensional papermaking technology. It uses pulp made from waste paper as raw material and uses special molds on a molding machine to shape paper products of a certain shape. It has four major advantages: the raw materials are waste paper, including cardboard, waste carton paper, waste white-edge paper, etc., which are widely available; its production process is completed by pulping, adsorption molding, drying and shaping, etc., which is harmless to the environment; it can be recycled and reused; its volume is smaller than that of foamed plastics, it can be overlapped, and transportation is convenient. In addition to making lunch boxes and tableware, pulp molding is more used for industrial cushioning packaging, and it has developed very rapidly. Items such as egg trays and electrical appliance trays made of pulp molding can all be called pulp molded products;

[0003] When making the pulp needed for pulp molding, you first need to use a shredder to cut the waste paper into pieces, then soak it in warm water for an hour, then pour it into a blender to stir it into pulp, and finally pour the pulp stirred by the blender into the pulp screen for filtration, screening and dehydration to improve the quality of the finished product.

[0004] The patent with application number CN202223140151.6 discloses a pulping slurry screening device for the production of pulp molded products, including a screening device body, a screening frame is installed in the middle position of the upper end surface of the screening device body, and a through hole is provided near the middle position on the front and rear end surfaces of the screening frame; a stepper motor installed on the outer surface of the screening device body is provided on the front and rear sides of the screening frame, and a rotating shaft is connected to the surface facing the screening frame on the two stepper motors, and a connecting rod is provided on the surface facing the screening frame on the rotating shaft, and a rectangular parallelepiped groove is provided inside the rotating shaft. The utility model has two stepper motors installed on the outer surface of the screening device that can drive the screening frame to rotate. Under the action of the telescopic structure and the clamping structure, the stepper motor connected to the screening frame can be quickly replaced. The above technical solution can effectively prevent the stepper motor from being damaged, thereby causing the device to be unusable.
