Description

Technical Field

[0001] The utility model belongs to the technical field of bamboo fiber production, and specifically relates to a decomposition and grinding machine for extracting bamboo fiber. Background Art

[0002] The decomposition grinder for bamboo and wood fiber extraction is a mechanical equipment specially used to decompose bamboo and wood materials into fibers. This equipment plays a vital role in the extraction process of bamboo and wood fibers. It can efficiently grind bamboo and wood materials into fine fibers for subsequent processing and use.

[0003] The prior art discloses a material stirring device (CN114797528A) for the production of bamboo-wood fiber integrated wall panels, comprising a mixing box fixed on a base, the inner wall of the mixing box being a grinding surface, a grinding mechanism being arranged on the base, the grinding mechanism comprising grinding balls, and the grinding mechanism drives the grinding balls to rotate and cooperate with the inner wall of the mixing box to grind and mix the materials inside the mixing box, a swinging mechanism being arranged on the grinding mechanism, and the grinding mechanism drives the swinging mechanism to drive the grinding balls to swing back and forth in the mixing box while grinding the materials, thereby dispersing and mixing the materials, a suction circulation mechanism being arranged on the grinding mechanism, and the grinding mechanism drives the suction circulation mechanism to transport the materials in the direction of the swinging of the grinding balls while grinding the materials.

[0004] When in use, the above-mentioned device utilizes the back-and-forth swinging of the grinding balls and the coordination between the mixing boxes to grind the bamboo and wood fibers. However, since the swinging direction of the grinding balls cannot be changed, some fibers adhere to the inner wall of the mixing box and cannot be ground, resulting in poor grinding effect of the device as a whole. Furthermore, due to the special structural shape of the mixing box, there will be certain dead corners and difficult-to-clean angles when cleaning, which is inconvenient to clean and also affects the hygiene of the device.
