first fixing frame 43 move leftward on the first supporting frame 41, at this time, the rotating saw blade 49 will complete the sawing work of the wood, the sawed wood will directly drop from between the first conveying device 2 and the second conveying device 3, so that the front end of the wood will be kept neat, after the cutting is completed, the first air cylinder 44 will be shortened, the first fixing frame 43 will move rightwards on the first supporting frame 41 and return to the original position, and at the same time, the clasping mechanism 6 on the first conveying device 2 will also return to the original position, then the first conveying device 2 will continue to operate under the control of the PLC control system, when the wood material continues to move forwards to the guiding mechanism 7 on the second conveying device 3, because the guiding mechanism 7 on the second conveying device 3 and the guiding mechanism 7 on the first conveying device 2 have the same structure and working principle, similarly under the cooperation of the PLC controller 141 and the first photoelectric sensor 143 on the second conveying device 3, the guiding mechanism 7 on the second conveying device 3 can be controlled to complete the guiding function to the wood material, so as to promote the wood material to stably move on the second conveying device 3, and at the same time, the PLC controller 141 will control the fourth air cylinder 82 to extend, and the blocking piece 84 can be driven to correspondingly rotate by the rotation of the connecting rod 83, until the blocking piece 84 is positioned right ahead of the moving of the wood, when the third photoelectric sensor 145 senses the wood, the PLC controller 141 simultaneously controls the first conveying device 2 and the second conveying device 3 to stop operating, at this time, the blocking piece 84 can effectively block the wood from continuing to move forward under the action of inertia, then the PLC controller 141 can control the holding mechanism 6 on the second conveying device 3 to work, because the holding mechanism 6 on the second conveying device 3 and the holding mechanism 6 on the first conveying device 2 have the same structure and working principle, the fixing work of the wood can be completed in the same way, meanwhile, the fourth cylinder 82 can be shortened under the control of the PLC controller 141, and drives the blocking piece 84 to recover to the original position, at this time, the pressure switch 142 positioned on the second conveying device 3 can judge whether the holding degree of the wood by the holding mechanism 6 meets the safe operation requirement by detecting the air pressure value in the second cylinder 62 connected with the pressure switch, until the holding force of the holding mechanism 6 to the wood reaches the safety standard, the cutting device 4 can be controlled to complete the fixed-length cutting of the wood under the control of the PLC controller 141, after the cutting is completed, the cutting device 4 and the holding mechanism 6 on the second conveying device 3 can also be restored to the original position, then the first conveying device 2 and the second conveying device 3 can continue to operate under the control of the PLC controller 141, the cutting of the wood is continued to be completed according to the working principle, when the remaining wood is short, the wood can fall from between the first conveying device 2 and the second conveying device 3 or can be continuously conveyed by the second conveying device 3, the cut wood can continue to move forwards on the second conveying device 3, when the wood moves from the second conveying device 3 to the third conveying device 9 and collides with the baffle 99, the vibration sensor 150 can sense the vibration of the baffle 99, under the action of the PLC controller 141, the third conveyor 9 stops operating, and at the same time, the fifth cylinder 95 is controlled to extend, since the fixed end of the fifth cylinder 95 is hinged to the second frame 91, the movable end of the fifth cylinder 95 is hinged to the fixing rod 98, thereby driving the roll-over stand 94 to rotate around the first connecting shaft 96 as a central axis, and simultaneously pushing away the wood on the second frame 91 to a specific position, in the process of cutting the wood, when the first photoelectric sensors 143 on the first conveying device 2 and the second conveying device 3 cannot sense the existence of the wood, the guide mechanism 7 can automatically return to the original position under the control of the PLC 141, when the fourth photoelectric sensor 146, the fifth photoelectric sensor 147, the sixth photoelectric sensor 148 and the seventh photoelectric sensor 149 on the first conveying device 2 do not sense the existence of the wood, the PLC controller 141 controls the second motor 123 to operate and continue to supply the first conveyor 2.
