The working principle of the invention is as follows:

referring to fig. 2-24, when the log processing system for increasing efficiency and reducing personnel works, firstly, logs 17 are placed on a feeding frame 11 of a feeder 1 and enter a J-shaped feeding claw 13 through the transportation of a feeding chain 12; the J-shaped feed claw 13 then sends the logs 17 at intervals to the carriage 2 and is clamped by the J-shaped holding claw 27. The carriage 2 is then moved along the rail to the band saw machine 3, where the cutting of the logs 17 is started by the saw blade 32. Meanwhile, the material holding device 4 starts to work, and the material holding cylinder 44 pushes out the material holding sliding table 42, so that the material holding roller 47 is positioned above the front conveyor belt 6. Then, along with the advancing of the carriage 2 and the sawing of the log 17, the plates cut on the log 17 but not completely cut off start to contact with the material holding roller 47, and the material holding roller 47 tightly presses the plates to press the plates to the log 17 through the supporting action of the gas spring 45, so that the material holding operation is realized. After the sawing of the log 17 is finished, the roadster 2 resets through the rail, the material holding cylinder 44 drives the material holding sliding table 42 to reset to prepare for the next round of sawing; the completely sawn sheet material falls onto the front conveyor belt 6 under the action of its own weight, moves forward by the rotation of the front rollers 62 and can be transported edgewise by the roller screw teeth 67.

When the arc-shaped side plates 37 are sawn from the logs 17, the lifting cylinder 55 of the side-shifting conveyor 5 is not operated, and the conveying table 52 is still positioned below the front roller 62; the swing cylinder 74 of the rear conveyor belt 7 does not work, and the height of the upper end of the limit plate 76 is still lower than that of the rear roller 72. Therefore, the arc-shaped edge plate 37 can normally pass through the rear conveyor belt 7, and is conveyed to the end of the rear conveyor belt 7 and then is carried away by a worker. Finally, each part is reset and waits for the next round of work.

When the square material plate 36 is sawn from the log 17, the swing cylinder 74 of the rear conveyer belt 7 works, the piston rod of the swing cylinder 74 extends out, the limit plate 76 swings around the hinge shaft 75, the upper end of the limit plate 76 is higher than the rear roller 72, and the front end of the square material plate 36 is blocked by the limit plate 76 and cannot advance and stays at the tail end of the front conveyer belt 6. Then, the jacking cylinder 55 of the side shift conveyor 5 operates, the piston rod of the jacking cylinder 55 extends out to drive the conveying table 52 to rise to a height higher than the front roller 62, and the square material plate 36 staying on the front conveyor 6 is jacked up by the conveying chain wheel 523 on the conveying table 52 and leaves the front conveyor 6. Then the power motor 56 works, the conveying chain wheel 523 is driven to work through the transmission action, the square material plate 36 on the conveying chain wheel 523 is conveyed to the material storage platform 53, slides to the front of the supporting square pipe 54 through the rolling fit with the material storage bearing 531, and is then carried away by a worker. Finally, each part is reset and waits for the next round of work.

After the square material plate 36 and the arc-shaped side plate 37 are separated, the square material plate 36 is moved to the material plate transition frame 81 by a worker, and then the square material plate 36 is moved to the middle part of the edge cleaning and material changing integrated machine 83 to carry out an edge cleaning and slicing process; the arc-shaped edge plate 37 is moved to the side part of the edge cleaning and material changing integrated machine 83 to carry out the plate skin material changing process. The processed square material plate 36 and the processed arc-shaped side plate 37 can be returned to the material plate transition frame 81 again through the material returning conveying frames 82 arranged on the two sides of the edge cleaning and material changing integrated machine 83. Finally, the worker moves the processed square material plate 36 and the processed arc-shaped side plate 37 to the middle of the square wood multi-blade saw 84 through the material plate transition frame 81, and finally cuts the square material plate and the arc-shaped side plate into the specification plates.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
