Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and more specifically, to a crushing device for papermaking raw materials. Background Technology

[0002] Papermaking technology is specifically divided into two forms: machine-made and hand-made. Machine-made papermaking is a continuous process on a papermaking machine. Pulp suitable for paper quality is diluted with water to a certain concentration, and then initially dewatered on the wire section of the papermaking machine to form a wet sheet. This sheet is then pressed to remove more water and finally dried to form paper. Hand-made papermaking uses a frame with bamboo screens, polyester mesh, or copper mesh to form a wet sheet of dispersed and suspended fibers in water. This sheet is then pressed to remove more water and then dried in the sun or by baking to form paper.

[0003] Application No. 202323168045.3 discloses a crushing device for papermaking raw materials, including a main body of equipment, a sealing baffle provided on one side of the inner end face of the main body of equipment, a discharge port provided on the bottom outer end face of the main body of equipment, a motor provided on one side of the lower part of the main body of equipment, a drive shaft provided on one side of the upper end of the motor, a cover provided on one side of the upper end of the main body of equipment, and a stirring shaft column provided inside the main body of equipment. This invention provides a location for the internal crushing structure by incorporating a stirring shaft column within the main body of the equipment. Four sets of stirring rollers of varying heights are arranged around the upper and lower ends of the stirring shaft column, with metal counterweights at the ends of the rollers. This allows the rollers to exert greater weight during crushing. Stirring teeth are located around the metal counterweights, enabling the equipment to more easily shred papermaking raw materials. However, this device, relying solely on stirring rollers, metal counterweights, and stirring teeth, is insufficient for thoroughly crushing papermaking raw materials. Furthermore, the crushed material requires filtration to ensure quality. Conventional methods rely solely on filter screens, which require manual cleaning when clogged, impacting production efficiency.
