A driving rod 77 is coaxially arranged between the two driving sprockets 721 of the first sprocket assembly 71 and one driving sprocket 721 of the second sprocket assembly 72 in a penetrating manner, the driving rod 77 is fixedly connected to all the driving sprockets 721, the turnover motor 78 is fixedly installed on one side of the connecting plate 75, a rotating shaft at the end of the turnover motor 78 is fixedly connected to the driving rod 77, the driving sprocket 721 and the driven sprocket 722 are both meshed with the transmission chain 76, and the driving rod 77 simultaneously penetrates through the two connecting plates 75 and is rotatably connected to the two connecting plates 75 through bearings. The cylinder end of the first cylinder 73 is pivotally connected to the upper end of the base plate 64, the rod end of the first cylinder 73 is pivotally connected to the lower end of the connecting plate 75 of the second sprocket assembly 72, the cylinder end of the second cylinder 74 is pivotally connected to the upper end of the base plate 64, and the rod end of the second cylinder 74 is pivotally connected to the lower end of the connecting plate 75 of the first sprocket assembly 71.
After cutting one side of the log, it needs to be turned over. And simultaneously starting the third pressure cylinders 65, lifting the turnover mechanism 70 by the third pressure cylinders 65, enabling the logs to abut against the surfaces of the first chain wheel assembly 71 and the second chain wheel assembly 72 simultaneously, and driving the second chain wheel assembly 72 and the first chain wheel assembly 71 to rotate to a state of being difficult to fall off by the first pressure cylinders 73 and the second pressure cylinders 74 respectively. When the turning motor 78 is started, the driving sprockets 721 of the first sprocket assembly 71 and the second sprocket assembly 72 rotate to drive the first sprocket assembly 71 and the second sprocket assembly 72 to drive in the same direction, thereby turning the logs. When the log is turned to the position where the log is needed to be cut and the cutting tool is opposite to each other, the first pressure cylinder 73 and the second pressure cylinder 74 respectively drive the second chain wheel assembly 72 and the first chain wheel assembly 71 to rotate to the initial state, and the third pressure cylinder 65 drives the bottom plate 64 to slowly fall back to the initial position.
The implementation principle of the high-efficiency wood cutting assembly line in the embodiment of the application is as follows: logs are fed from the side of the transport mechanism 10 and are then sequentially transferred to the positioning mechanism 20, and the positioning mechanism 20 adjusts the axial position of the logs. After the position adjustment, the guiding assembly 41 guides the log onto the table 43, and after the positioning mechanism 50 fixes the position of the log, the table 43 is pulled to the cutting mechanism 90 side, and the cutting mechanism 90 cuts the round edge of the log while moving. After the round edge on one side is cut, the turning mechanism 70 turns the log, adjusts the cutting surface of the log, and then continues the cutting process. After the cutting is completed, the positioning mechanism 50 is released from the fixing, and the log is taken down.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
