Background
In the field of chipboard production, spreading of wood shavings refers to uniformly and continuously spreading the metered glue-applied wood shavings into chipboard slabs before hot pressing, which determine the properties and performance fluctuation of the final board.
The requirements for a paving system depend on: (1) The type of raw material (material type, wood flake morphology and weight); (2) Final product requirements (sheet structure, thickness and sheet smoothness); (3) throughput of the production line. This determines the working principle of the head and its number.
The material constituting the slab is composed of shavings, non-uniform particles such as fibers, dust, etc., that is, shavings of different sizes and shapes, and even contains high-density sand and stone components for recycling wood raw materials. To achieve a smooth transition of the shavings size in the thickness direction of the slab, a reasonable grading of shavings is necessary to obtain a uniform and fine surface.
EP2626179B1 provides a composite surface layer paving head combining a roller paving head and an air flow paving head for recycling wood raw materials containing a large amount of impurities. The combined paving head has the outstanding advantages that fine shavings are blown onto a fine roller suitable for classifying the fine shavings through air flow above the roller bed, the outermost layer of the slab is formed through classification, heavier shavings such as particle shavings and mineral gravel can be completely blown onto a coarse roller bed, meanwhile, light flaky shavings can be blocked on the coarse roller bed by a screen arranged above the roller bed, and the light flaky shavings are separated into slabs deeper from the slab through the coarse roller, so that better slab quality and slab edge performance are obtained.
However, in practical production, it has been proved that the precision of the material distributed by the spreading device (wood shavings dispersing device) with such a structure in the transverse direction of production is not stable enough, and only the material quantity is small, and the air flow is kept stable under the laminar flow condition, when the material characteristics change, especially after the yield is increased, the air flow of the required dispersed material is also required to be increased, and the increased air flow speed leads to the occurrence of turbulence, which is uncontrolled, and causes the mixed material to float, so that the distribution of the slab (or the material mat) fluctuates.

Example 1
As shown in fig. 1 to 4, the present embodiment provides an airflow pavement apparatus with a cylindrical revolving body 6, which includes a pavement chamber 5 formed by a feeding port 1, a blowing device 2, an air-out device 3 and a bottom conveyor belt 4, wherein at least one cylindrical revolving body 6 with a surface permeable to airflow is disposed in the pavement chamber 5.
The surface of the cylindrical rotor 6 may be covered with a metallic or nonmetallic screen.
A plurality of partition plates 7 perpendicular to the central rotation axis are arranged in the cylindrical rotation body 6 at certain intervals.
In this embodiment, in order to solve the above technical problem, the idea of the present solution is to provide a cylindrical revolving body 6 outside the air door grille instead of the vibrating screen, where the cylindrical revolving body 6 may be a cylindrical revolving body 6, and a partition 7 corresponding to the air door grille is provided on the cylindrical revolving body 6, so that in the paving process, the cylindrical revolving body 6 not only has an effect of stabilizing airflow as a screen, but also can reduce the lateral movement of the material caused by the instability of the airflow in the range of the cylindrical revolving body 6 through the partition 7 provided inside the cylindrical revolving body 6, specifically, when the airflow carries the material to blow out from the air door grille, part of the material will move laterally along with the unstable airflow, and before the roller grille is not added, the lateral movement range is the whole box; after the cylindrical revolving body 6 is added, the transverse movement of the material is within the range of the baffle 7 of the cylindrical revolving body 6, so that the transverse movement of the material within a certain range is greatly reduced. Meanwhile, the cylindrical revolving body 6 continuously rotates in the normal operation process, and the cleaning device continuously cleans the net surface in the rotation process, so that the material is less prone to sticking compared with a common vibrating screen.
In the cylindrical revolving body 6, a plurality of partition plates 7 are transversely arranged in the cylindrical revolving body 6, and a layer of screen mesh is wrapped on the outer periphery of the cylindrical revolving body 6 to form the cylindrical revolving body 6; the cleaning device of this scheme can be various for example: the axial direction of the shaft of the cylindrical revolving body 6 inside the cylindrical revolving body 6 is provided with a plurality of small hammers 8 with lines (or each small hammer 8 with lines corresponds to a gap of a baffle 7, the small hammers 8 with lines at different axial positions are uniformly arranged along the circumference of the shaft of the cylindrical revolving body 6, and the specific view can be seen), in the rotating process of the cylindrical revolving body 6, the lines of the small hammers 8 with lines can be tightened by the small hammers 8 after being coiled by the shaft of the cylindrical revolving body 6, and then the small hammers 8 are hammered against a screen surface by gravity after being released instantly, so that the screen surface adhered materials fall off in vibration.

Further, on the basis of embodiment 1, a small hammer 8 is disposed in the cylindrical revolving body 6, the small hammer 8 is connected with the central rotation axis of the cylindrical revolving body 6 through a rope 9, and the small hammer 8 rotates along with the central rotation axis of the cylindrical revolving body 6 through the rope 9.
The number of the small hammers 8 is several, and the small hammers 8 are respectively arranged between the adjacent partition plates 7.
