An electromagnet 29 is fixedly installed at the bottom of the processing table 2 corresponding to the position of the fixed shell 24, and the transmission roller 26 is a magnetic material component, so that the electromagnet 29 magnetically attracts the transmission roller 26 and drives the elastic transmission belt 27 to fit tightly against the wood. The electromagnet 29 is energized to generate a magnetic field, and the electromagnet 29 generates suction on the transmission roller 26, so that the transmission roller 26 drives the elastic transmission belt 27 to fit tightly against the top of the wood, so that the wood will not move accidentally when being cut by the cutting saw 7.

[0039] At the same time, when the first transmission shaft 31 rotates, the first transmission shaft 31 will drive the second chain 10 through the second sprocket 9 and the third output shaft 8, so that the second chain 10 drives the first movable frame 12 to move, and when the first movable frame 12 moves to the top position of the processing table 2, the first movable frame 12 will drive the limiting plate 13 to move to the inner wall of the guide bracket 19, and the two ends of the C-shaped guide bracket 19 are respectively located between the two limiting plates 13, so that the movement of the first movable frame 12 can be stably guided by the guide bracket 19 and the limiting plate 13, and when the first movable frame 12 moves, due to the two ends of the driving bracket 20 The inclined setting will cause the driving bracket 20 to gradually squeeze the second movable frame 16 until the second movable frame 16 moves to the horizontal position of the driving bracket 20, and in the process of the driving bracket 20 squeezing the second movable frame 16, the second movable frame 16 will drive the squeezing plate 14 to squeeze the wood at both ends of the wood through the damping spring 17. Since the transmission of the second chain 10 and the transmission of the feeding push block 6 are both driven by the first transmission shaft 31, the moving speed of the first movable frame 12 is equal to the moving speed of the feeding push block 6, so that the damping spring 17 squeezes the wood while cooperating with the feeding push block 6 to drive the wood to move synchronously until the wood is cut by the cutting saw 7.

[0040] After the wood is cut, the waste will fit with the cutting saw 7. At this time, under the action of squeezing and moving of the squeezing plate 14, the waste will fall from one end of the movable groove 11 corresponding to the position of the baffle plate 21, thereby completing the purpose of waste separation.
