Paving device and corresponding mixing and paving system

The invention relates to the technical field of plate paving, in particular to a paving device and a corresponding mixing and paving system.

In the conventional plate making process, the raw materials are pulverized, ground into a powder, and then mixed with the glue. The mixed materials have certain sliding characteristics, and are laid on the template frame even if the materials are laid unevenly. However, under the rolling action of the flat rolls in the later stage, the uneven materials will slide to the position where the material is less, such as the dough that has been licked by the rolling pin, and will be flattened by the external force. In the existing industrial production, the same is true for the processing of the sheet material using straw as a raw material. However, after the straw is pulverized, the toughness and pinching power of the straw itself will not be exerted on the board, and the board made of the crushed straw will have poor drill resistance, but if the strip or strip is used to make the sheet, Moreover, due to its strong cohesive force and no sliding property, the straw cannot be uniformly mixed, and even if it is made into a plate, the effect of the straw cannot be fully exerted.

In view of this, the present invention provides a paving device and a corresponding mixing material paving system to improve the existing drill straw sheet with poor drill resistance, or to make the straw having a good toughness, and the straw cannot be uniformly mixed.
