[0005] Furthermore, both side portions of the driving shaft are rotatably connected to the frame of the peeling machine via bearing seats, and a sprocket is installed at one end of the driving shaft.

[0006] Furthermore, knurling is provided on the circumferential surface of the disc-shaped pressing roller.

[0007] Furthermore, the middle parts of the disc-shaped pressure roller and the toothed disc are both provided with shaft holes for the driving shaft to pass through, and the shaft holes are provided with keyways.

[0008] Furthermore, a pair of keyways are symmetrically arranged in the shaft hole.

[0009] Furthermore, one side of the disc-shaped pressure roller is provided with an annular protrusion and a limiting flange for abutting against the side of a toothed disk, and the other side of the disc-shaped pressure roller is a plane and is used to fit with another toothed disk.

[0010] Furthermore, the other end of the driving shaft is threadedly connected with a locking ring that abuts against the outermost gear disc, and a locking bolt that is threadedly connected to the outermost gear disc is axially penetrated through the locking ring.

[0011] Furthermore, pressure bars are installed in the gaps between two adjacent groups of disc-shaped pressure rollers and the toothed disc on the frame of the peeling machine, and wear-resistant blocks are installed at the lower ends of the pressure bars.

[0012] Furthermore, a transverse through groove is provided at the lower part of the pressure bar and toward the cutter side, a transverse gap is longitudinally provided on the side wall of the transverse through groove, and the wear-resistant block is arranged in the transverse through groove and clamped by a locking bolt vertically passing through the transverse gap.

[0013] Compared with the prior art, the utility model has the following advantages: the driving roller has a compact structure, and the convex teeth on the toothed disc form continuous concave points on the wood sheet cut from the rotary cutting, which helps the glue to penetrate into the wood sheet during the subsequent gluing, thereby improving the gluing effect of the wood sheet. This structure can also destroy the fibers of the veneer to a certain extent, making the cut veneer softer and reducing the occurrence of curling. In addition, a wear-resistant block is installed on the pressure bar arranged between two adjacent disc-shaped pressure rollers, which helps to improve the wear resistance of the pressure bar.

DETAILED DESCRIPTION

[0022] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0023] refer to Figures 1 to 7

[0024] A main structure of a rotary cutter driving roller includes a driving shaft 20, which is used for horizontal rotation and connected to a crossbeam 11 below a rotary cutter frame 10. A plurality of disc-shaped rollers 30 are installed on the driving shaft along the axial direction at intervals, and a knurling is arranged on the circumferential surface of the disc-shaped roller to increase the friction between the roller and the log; a toothed disc 40 is fitted on one side of the disc-shaped roller, and the convex teeth 41 of the toothed disc protrude from the circumferential surface of the disc-shaped roller. The log is driven to rotate by the plurality of disc-shaped rollers; and the convex teeth extend out of the circumferential surface of the disc-shaped roller, so that continuous concave points can be formed on the cut wood sheet, which is conducive to the subsequent gluing, so that the glue can better penetrate into the wood sheet, and the firmness of the gluing can be improved; at the same time, the fibers of the veneer can be destroyed to a certain extent, so that the cut veneer is softer and the generation of rolled board can be reduced.

[0025] In this embodiment, both sides of the driving shaft are rotatably connected to the crossbeam below the peeling machine frame via the bearing seat 21, and a sprocket 22 is installed at one end of the driving shaft so as to drive the driving shaft to rotate through the chain.

[0026] In this embodiment, the middle parts of the disc-shaped pressure roller and the toothed disk are provided with shaft holes 31 and 42 for the drive shaft to pass through, and the shaft holes are provided with keyways 32 and 43 to ensure that the disc-shaped pressure roller and the toothed disk will not slip on the drive shaft.

[0027] In this embodiment, a pair of keyways are symmetrically arranged in the shaft hole, thereby improving the circumferential limiting strength.

[0028] In this embodiment, one side of the disc-shaped pressure roller is provided with an annular protrusion and a limiting flange 33 for abutting against the side of a toothed disk, and the other side of the disc-shaped pressure roller is a plane and is used to fit with another toothed disk.

[0029] In this embodiment, the other end of the driving shaft is threadedly connected to a locking ring 23 that abuts against the outermost gear disk, and a locking bolt 24 is axially penetrated through the locking ring and threadedly connected to the outermost gear disk; a notch is provided on the circumferential surface of the locking ring along the circumferential direction for driving the locking ring to rotate.

[0030] In this embodiment, pressure bars 50 are installed in the gaps between two adjacent groups of disc-shaped pressure rollers and toothed discs on the frame of the peeling machine, and wear-resistant blocks 60 are installed at the lower ends of the pressure bars.

[0031] In this embodiment, a transverse through groove 51 is provided at the lower part of the pressure strip and toward the cutter side, a transverse slit 52 is longitudinally provided on the side wall of the transverse through groove, and a transverse hollow circular groove is connected to the end of the transverse slit away from the transverse through groove so that the transverse through groove forms a clamping groove; the wear-resistant block is arranged in the transverse through groove and clamped by a locking bolt 53 which vertically passes through the transverse slit and is screwed to the pressure strip.

[0032] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0033] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0034] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0035] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
