[0028] Furthermore, a vertical baffle 5 is provided on the frame 1, and the support plate 61 and the transverse feeding device 2 are respectively arranged on both sides of the vertical baffle 5. A plurality of cutting openings 51 are provided on the vertical baffle 5, and the cutting knife 31 can pass through the cutting opening 51. The horizontal side of the log 8 can abut against the vertical baffle 5, which can limit the backward movement of the log 8, thereby further enhancing the firmness of the log 8 and facilitating the cutting of the log 8.

[0029] Furthermore, the inner side of the buckle 4 is curved, that is, the inner side surface of the buckle 4 is curved, and can naturally abut against the log 8 after flipping, and during the flipping process, the log 8 can be driven to roll toward the vertical baffle 5 and gradually pressed to a suitable cutting position, and this process causes little damage to the wood and has high smoothness; in addition, the method of driving the buckle 4 to rotate and then buckle the wood by the rotating shaft 7 can reduce the requirements for the drive motor 33, thereby reducing costs.

[0030] Furthermore, the transverse feeding device 2 includes a guide rail 22, a slider 23 and a linear drive device 21, the output end of the linear drive device 21 is drive-connected to the slider 23, and the slider 23 is slidably connected to the guide rail 22; the cutting device 3 also includes a driving motor 33 and a driving shaft 32, the cutting blade 31 is installed on the driving shaft 32, the driving motor 33 is installed on the slider 23 through a machine base and is driven and connected to the driving shaft 32 through a chain drive.

[0031] Furthermore, the receiving assembly 6 also includes a transverse baffle 63 and a base frame 62, the transverse baffle 63 is fixedly connected to the upper side of the base frame 62, and the support plate 61 is fixedly connected to the transverse baffle 63. Specifically, the base frame 62 includes a bottom plate 621 and a rear baffle 622, and the bottom plate 621, the rear baffle 622 and the transverse baffle 63 are connected in a box shape, which has high stability and allows the rotating shaft 7 to be set on the inner side, thereby improving the protection of the rotating shaft 7; an axle seat is installed on the bottom plate 621 or the support plate 61, and a bearing is provided on the outer sleeve of the drive shaft 32, and the bearing is assembled on the axle seat, thereby realizing the rotation of the rotating shaft 7 relative to the base frame 62; in addition, a rotating drive motor 33 can be installed at one end of the frame 1 to directly coaxially drive the rotating shaft 7 to rotate.

[0032] Furthermore, a clearance hole 631 is provided on the transverse baffle 63, and the buckle 4 passes through the clearance hole 631 after being flipped over, so that the buckle 4 can be flipped over and stored under the transverse baffle 63. The advantage of such a setting is that after the buckle 4 is flipped over and stored under the transverse baffle 63, the top surface of the transverse baffle 63 is smooth, and the wood can move smoothly from the transverse baffle 63 to the support plate 61; the smoothness of feeding can be improved, the conveying efficiency can be improved, and the processing preparation time can be shortened.

[0035] Example 2

[0036] On the basis of Example 1, the rotating shaft 7 is connected to a toggling assembly 10 for toggling the wood segment through an intermittent transmission assembly 9. The toggling assembly 10 includes a toggling shaft 101 and a plurality of toggling plates 102 fixed on the toggling shaft 101. The wood segment is easier to get stuck on the support plate 61, so it is convenient for the toggling plate 102 to be set against the support plate 61, so as to facilitate toggling the wood segment and causing it to fall.

[0038] Specifically, the toggle plate 102 is a bent plate, and the upper part of the toggle plate 102 is bent toward the vertical baffle 5. It tends to flip downward under the action of gravity and maintains the original state through gear meshing; the incomplete gear used by the driving gear 91 specifically includes a number of closely adjacent teeth. When the driving gear 91 rotates, the upper part of the toggle plate 102 flips upward, which can lift up part of the wood segments stuck on the support plate 61, so that all the wood segments fall down. During the process of the wood segments falling down, the driven gear 92 is separated from the driving gear 91, and the gravity is still on the same side of the toggle shaft 101. Under the action of gravity, it will automatically flip down and mesh with the driving gear 91 again, thereby realizing cyclic toggling and preventing the wood segments from being blocked.
