Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a raw material crusher for preparing fiberboards. Background Art

[0002] Fiberboard refers to a man-made board made of wood cellulose fibers interwoven and made using their inherent adhesive properties. Adhesives and / or additives may be applied during the manufacturing process. Fiberboard, also known as density board, is a man-made board made of wood fiber or other plant fiber as raw materials, with urea-formaldehyde resin or other suitable adhesives applied.

[0003] From the production process of fiberboard, it can be seen that its raw materials mainly come from various dried plant powders, which can be straw powder, sawdust powder, bamboo fiber powder, etc. The raw materials are not necessarily various powder structures, but block structures. Therefore, they need to be fully crushed before pressing, and because the block structure is difficult to dry inside, drying operation is required after crushing.

[0004] Before crushing, the raw materials have different sizes, different water contents, and different hardness, which puts a lot of pressure on the crushing device, so that the finished product still contains a certain amount of large block structures after crushing, and it needs to be crushed again. Therefore, it is necessary to design a more efficient and reasonable crushing device. Utility Model Content

[0005] The utility model aims to provide a raw material crusher for preparing fiberboard, which can crush fiber raw materials more efficiently and reduce the burden of crushing equipment.

[0006] The embodiment of the utility model is realized through the following technical scheme: the raw material crusher for fiberboard preparation of the utility model comprises a horizontally arranged feed plate, enclosures arranged on both sides of the feed plate, a pressing plate arranged above the feed plate, a cutting device arranged at one end of the feed plate, a crushing device arranged below the cutting device, a feed port arranged at one end of the pressing plate away from the cutting device, a push plate slidably arranged between the feed plate and the pressing plate, and a first driving device for driving the push plate to reciprocate along the feed plate; the push plate is arranged on the side of the feed port away from the cutting device.
