Description
Technical Field
The invention relates to the technical field of paving equipment, in particular to airflow paving equipment with a circulating network belt.
Background
The wood shavings are paved into uniform plate blanks according to the specified weight, specification and the like by a certain paving method after glue mixing before hot pressing. The importance of the paving process is that the quality of the slabs has a decisive influence on the performance of the particle board!
The density of the chipboard pressed by the plate blanks paved uniformly is consistent, the expansion and the shrinkage of each part in the chipboard are also consistent, the warping deformation is not easy to occur, and the physical and mechanical properties of the plates are also consistent. Therefore, in order to obtain a uniform board quality, the laying of the chipboard slabs must meet specific requirements.
The existing surface layer of the shaving board is formed by a pneumatic paving head. Based on the geometry of the shavings, it is possible to arrange the shavings in the desired order using pneumatic classification. Through one or more stable air flows, the tiny shavings are taken away and firstly fall onto the paving belt to form a fine surface layer formed by the tiny shavings, and the bigger and heavier shavings are less influenced by the air flow and can only fall on the formed tiny shavings layer to form a coarse shavings layer or an intermediate layer. EP2626179B1 describes a composite paving head combining the advantages of both a mechanical roller paving head and an air flow paving head for staged paving of particle board skins, which is widely used in current large scale industrial production.
However, with the continuous expansion of the raw tree species of the chipboard, for some special tree species such as paper mulberry, eucalyptus, cypress, etc., after the processing links of chipping, flaking, drying, screening, etc., the bark and phloem thereof are difficult to be completely separated from the xylem and removed, so that the long fibers in the bark and phloem thereof enter the surface wood shavings in the form of fluff of different sizes. These long fluff fibers not only tend to bind the classifying screens of the air flow laying head, resulting in a decrease in classifying efficiency, but also tend to intertwine on the rotating mechanical roller bed to form fluff balls, severely affecting the classifying ability of the roller bed. The existing self-cleaning design of the vibrating motor and the roller bed arranged on the screen can not effectively eliminate the adverse effect caused by the fluffy long fibers, and only can be frequently stopped for manual cleaning, so that the production efficiency of the production line and the stability of products are seriously affected.
DE102008011056a discloses a movable or rotatable cleaning belt parallel to the screen surface in a spreading machine for continuously cleaning agglomerations agglomerating on the screen, but this internal cleaning approach causes the agglomerations to fall into the spreading mat, forming a significantly high density spot or face.
Therefore, how to effectively separate and remove impurities in raw materials becomes a great problem in the industry.
