Description

Technical Field

[0001] The utility model relates to the technical field of stirring rods, in particular to a stirring rod assembly for fiberboard processing. Background Art

[0002] Fiberboard, also known as density board, is a man-made board made from wood fiber or other plant fiber as raw materials, with urea-formaldehyde resin or other suitable adhesives applied. Adhesives and / or additives can be applied during the manufacturing process. Fiberboard has the advantages of uniform material quality, small difference in longitudinal and transverse strength, and not being prone to cracking, and is widely used. During pulping, in the chemical mechanical method, a small amount of chemicals such as caustic soda and sodium sulfite are used to pretreat the raw materials, so that lignin and hemicellulose are damaged or dissolved to a certain extent, and then separated into fibers by the action of mechanical force. Stirring rods are used during this period to both evenly distribute the chemicals and separate the fibers with mechanical force. However, during this process, the stirring resistance is extremely large, the stirring position is limited, resulting in uneven stirring, and the existing stirring rods often adhere to a lot of raw materials, and a lot of raw materials are lost during each processing, which is very uneconomical. Generally, the lower end surface of the stirring rod is suspended, so it is often not that firm.

[0003] Chinese Patent Publication No. CN220900076U, an artificial fiberboard raw material mixer publicly disclosed on May 7, 2024. The key points of its technical solution are that by setting a knocking mechanism, the knocking mechanism can knock down the raw materials attached to the surface of the stirring blades while stirring the raw materials of the artificial fiberboard, preventing waste of raw materials and reducing the cleaning difficulty of subsequent devices. The driving motor drives the connecting shaft to rotate, thereby driving the first transmission wheel, the belt, and the second transmission wheel to rotate, and then driving the driven shaft and the cam to rotate, which is used to solve the problem that when using the stirring blades to stir and mix the raw materials of the fiberboard, the raw materials will adhere to the surface of the stirring blades, and it is difficult for the mixer in the above-mentioned comparative patent to knock down the raw materials attached to the surface of the stirring blades when stirring the raw materials, so it may cause waste of raw materials and increase the cleaning difficulty of the device; by setting a knocking rod and a knocking ball, the knocking ball knocks down the corresponding stirring blade downward, so that the raw materials attached to the surface of the stirring blade can be knocked and vibrated down. The deficiencies of this utility model are that the stirring position is limited, often having to solve the problem of adhering to a lot of raw materials and not being firm enough.
