Description

Technical Field

[0001] The utility model relates to the field of wood processing, and particularly to a reduced air return structure of a wood slicing and dispersing machine. Background Art

[0002] After being sliced and dispersed, wood chips are mostly used for furniture boards, building formworks, papermaking and other purposes. In the existing wood slicing and dispersing machine, since the number of cutter disks installed on the cutter disk rotating shaft is small, it can only process and disperse wood with larger slices. When it is necessary to process small wood slices, the number of cutter disks used needs to be increased so that the processed and dispersed wood flakes are smaller to meet the production requirements. In the existing equipment structure, due to a large gap between the cutter disk protective cover and the cross beam, when the number of cutter disks used on the cutter disk rotating shaft is increased, a large amount of air return will be generated at this gap, which causes the processed wood flakes to fly out at the gap, and the wood flakes cannot fall below the cutter disk rotating shaft through the discharge plate. 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 reduced air return structure of a wood slicing and dispersing machine. After the number of cutter disks used is increased, by adding a windproof plate on the frame plate at the gap between the cutter disk protective cover and the cross beam, when the cutter disk rotates, through the cutter disk openings of the windproof plate, the air return at the gap can be reduced, and the thin wood chips sliced and dispersed by the cutter disk can fall below the cutter disk rotating shaft through the discharge plate.

[0004] The utility model is realized by the following technical solutions:

[0005] A reduced air return structure of a wood slicing and dispersing machine includes a cutter disk rotating shaft, and a number of cutter disks are equidistantly installed on the cutter disk rotating shaft. It also includes a windproof plate, and a number of cutter disk openings are formed on the windproof plate. The number of cutter disk openings cooperates with the number of cutter disks, and the plate body of the windproof plate extends towards the cutter disk rotating shaft between the cutter disks.

[0006] Further, a number of weight reduction holes are formed on the cutter disk. When the number of cutter disks increases, the overall load weight of the cutter disk rotating shaft can be reduced.

[0007] Further, it also includes a fixing plate, which is installed on the frame plate at the gap between the cutter disk protective cover and the cross beam. The windproof plate is installed on the fixing plate, and the windproof plate is installed vertically. When the cutter disk rotates, it passes through the cutter disk openings.

[0008] Further, the fixing plate is welded to the frame plate, and the windproof plate is installed on the fixing plate through bolts and nuts.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. After the number of cutter discs used increases, by adding a windproof plate on the frame plate at the gap between the cutter disc protective cover and the cross beam, when the cutter disc rotates, through the cutter disc openings of the windproof plate, the return air at the gap can be reduced, and the thin wood chips scattered by the cutter disc slicing can fall below the cutter disc rotating shaft through the discharge plate.

[0011] 2. By opening weight-reducing holes on the cutter disc, the overall load weight of the cutter disc rotating shaft can be reduced. Description of the Drawings

[0017] The present utility model will be further described and explained below in conjunction with the drawings.

[0018] Embodiment 1

[0019] As Figure 2 – Figure 4 shown, a structure for reducing return air of a wood chip slicing and dispersing machine includes a cutter disc rotating shaft 3, a plurality of cutter discs 2 are equidistantly installed on the cutter disc rotating shaft 3, and further includes a windproof plate 1, a plurality of cutter disc openings 4 are opened on the windproof plate 1, the plurality of cutter disc openings 4 cooperate with the plurality of cutter discs 2, and the plate body of the windproof plate 1 extends towards the cutter disc rotating shaft 3 between the cutter discs 2.

[0020] Embodiment 2

[0021] As Figure 1As shown in the figure, a structure for reducing return air of a wood slicing and dispersing machine. A number of weight-reducing holes 5 are provided on the cutter disc 2. When the number of cutter discs 2 increases, the overall load weight of the cutter disc rotating shaft 3 can be reduced. It further includes a fixed plate 8, which is installed on the frame plate 7 at the gap between the cutter disc protective cover 9 and the cross beam. The wind-proof plate 1 is installed on the fixed plate 8 and is vertically installed. When the cutter disc 2 rotates, it passes through the cutter disc opening 4. The fixed plate 8 is welded to the frame plate 7, and the wind-proof plate 1 is installed on the fixed plate 8 by bolts and nuts. The rest is the same as in Embodiment 1. The rest of the structure, connection relationship, etc. are all prior arts and will not be elaborated.

[0022] Increase the number of cutter discs 2 used on the cutter disc rotating shaft 3 (the number of cutter discs 2 used is 1-2 times the original). In order to reduce the overall weight, weight-reducing holes 5 are provided on the cutter disc 2. When the cutter disc 2 rotates, it passes through the cutter disc opening 4 of the wind-proof plate 1 to reduce the return air at the gap between the cutter disc protective cover 9 and the cross beam. The thin wood chips sliced and dispersed by the cutter disc 2 can then fall below the cutter disc rotating shaft 3 through the discharge plate 6.
