AI Technical Summary
After increasing the number of cutters, the existing wood slice breaker has severe return air in the gap, causing the wood sheet to fly out, and sealing the gap requires changing the external structure of the equipment and is costly.
A windproof plate is added at the gap between the blade protective cover and the beam, and an EVA-based annular sponge is filled between the blade. The return air is reduced through the blade opening of the windproof plate, and the return air is blocked by the ring sponge to ensure that the wood chip falls through the discharge plate.
It effectively reduces the return air, reduces the weight of the cutter wheel shaft, saves transformation costs, and achieves smooth discharge of wood chips.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of wood processing, and particularly to a knife disc filling and anti-air return structure for a wood slicing and dispersing machine. Background Art
[0002] After the wood slices are dispersed, they are mostly used for furniture boards, building templates, papermaking and other purposes. In the existing wood slicing and dispersing machine, since the number of knife discs installed on the knife disc rotating shaft is small, it can only process and disperse large sliced wood. When small wood slices need to be processed, the number of knife discs used needs to be increased so that the processed and dispersed wood thin slices are smaller to meet the production requirements. In the existing equipment structure, due to the large gap between the knife disc protective cover and the cross beam, when the number of knife discs used on the knife disc rotating shaft is increased, a large amount of air return will be generated at this gap, which will cause the processed wood thin slices to fly out at the gap, and the wood thin slices cannot fall below the knife disc rotating shaft through the discharge plate. And blocking this gap requires changing the external structure of the equipment, and the increased cost is also relatively high, which is obviously unreasonable. Content of the Utility Model
[0003] The purpose of the utility model is to provide a knife disc filling and anti-air return structure for a wood slicing and dispersing machine. After the number of knife discs used is increased, by adding a wind-proof plate on the frame plate at the gap between the knife disc protective cover and the cross beam, when the knife disc rotates, through the knife disc openings on the wind-proof plate, the air return at the gap above the knife disc is reduced, and the air return between the knife discs is blocked by the annular sponge filled with EVA material. In this way, the thin wood slices sliced and dispersed by the knife disc can fall below the knife disc rotating shaft through the discharge plate.
[0004] The utility model is realized by the following technical solutions:
[0005] A knife disc filling and anti-air return structure for a wood slicing and dispersing machine, including a knife disc rotating shaft, a plurality of knife discs are equidistantly installed on the knife disc rotating shaft, a filling layer is further arranged on the knife disc rotating shaft between the plurality of knife discs, and a wind-proof plate is further included. A plurality of knife disc openings are opened on the wind-proof plate, the plurality of knife disc openings cooperate with the plurality of knife discs, and the plate body of the wind-proof plate extends towards the filling layer between the knife discs.
[0006] Further, the filling layer is an annular sponge.
[0007] Further, the material of the annular sponge is EVA.
[0008] Further, a plurality of weight-reducing holes are opened on the knife disc. When the number of knife discs increases, the overall load weight of the knife disc rotating shaft can be reduced.
[0009] Furthermore, it also includes a fixing plate which is installed on the frame plate at the gap between the cutter head protective cover and the cross beam. The wind deflector is installed on the fixing plate and is vertically installed. When the cutter head rotates, it passes through the cutter head opening.
[0010] Furthermore, the fixing plate is welded to the frame plate, and the wind deflector is installed on the fixing plate by bolts and nuts.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. After the number of cutter heads used increases, by adding a wind deflector on the frame plate at the gap between the cutter head protective cover and the cross beam, when the cutter head rotates, it passes through the cutter head opening of the wind deflector to reduce the return air at the gap above the cutter head. The return air between the cutter heads is blocked by the annular sponge filled with EVA material. In this way, the thin wood chips scattered by the cutter head slicing can fall below the cutter head rotating shaft through the discharge plate.
[0013] 2. By opening weight reduction holes on the cutter head, the overall load weight of the cutter head rotating shaft can be reduced.
[0014] 3. Save the usage area of the wind deflector. With the use of the annular sponge, it can further reduce the overall weight of the cutter head rotating shaft and also reduce the transformation cost. Description of the Drawings

[0020] The present utility model will be further described and illustrated below with reference to the drawings.
[0021] Embodiment 1
[0022] As Figure 2 – Figure 4As shown in the figure, a windproof structure for filling a cutter head of a wood slicing and dispersing machine includes a cutter head rotating shaft 3, and a plurality of cutter heads 2 are equidistantly installed on the cutter head rotating shaft 3. A filling layer 10 is further provided on the cutter head rotating shaft 3 between the plurality of cutter heads 2. It also includes a windproof plate 1, and a plurality of cutter head openings 4 are formed on the windproof plate 1. The plurality of cutter head openings 4 cooperate with the plurality of cutter heads 2, and the plate body of the windproof plate 1 extends towards the filling layer 10 between the cutter heads 2.
[0023] Embodiment 2
[0024] As Figure 1 As shown in the figure, a windproof structure for filling a cutter head of a wood slicing and dispersing machine, the filling layer 10 is an annular sponge; the material of the annular sponge is EVA; a plurality of weight reduction holes 5 are formed on the cutter head 2. When the number of cutter heads 2 increases, the overall load weight of the cutter head rotating shaft 3 can be reduced; it also includes a fixing plate 8, and the fixing plate 8 is installed on the frame plate 7 at the gap between the cutter head protective cover 9 and the cross beam. The windproof plate 1 is installed on the fixing plate 8, and the windproof plate 1 is installed vertically. When the cutter head 2 rotates, it passes through the cutter head opening 4; the fixing plate 8 is welded to the frame plate 7, and the windproof plate 1 is installed on the fixing plate 8 through bolts and nuts, and the others are the same as in Embodiment 1.
[0025] Increase the number of cutter heads 2 used on the cutter head rotating shaft 3 (the number of cutter heads 2 used is about 1 times the original). In order to reduce the overall weight, weight reduction holes 5 are formed on the cutter head 2. When the cutter head 2 rotates, it passes through the cutter head opening 4 of the windproof plate 1 to reduce the return air at the gap above the cutter head 2. The return air between the cutter heads 2 is blocked by filling the annular sponge made of EVA material. In this way, the thin wood chips sliced and dispersed by the cutter head 2 can fall below the cutter head rotating shaft 3 through the discharge plate 6. It saves the usage area of the windproof plate 1, and with the use of the annular sponge, it can further reduce the overall weight of the cutter head rotating shaft 3 and also reduce the transformation cost.
