[0032] Reference Figure 1-Figure 5 In the utility model, when in use, a large silicon nitride plate is pushed between the clamping seats 2 on both sides, and then the turntable 43 is rotated to drive the threaded rod 42 to rotate. Since the threads on both sides of the threaded rod 42 are opposite, the sliding blocks 41 on both sides will move in opposite directions at the same time, thereby achieving the clamping of plates of different widths and improving the scope of application. Then the transmission motor drives one set of pulleys 52 to rotate, and the transmission effect between the guide rod 53 and the pulley 52 will make multiple sets of driving rollers 5 rotate at the same time, thereby pushing the plate on the clamping seat 2 to move. When the plate moves to the predetermined cutting length, the transmission motor stops rotating. At this time, the driving motor 72 and the cutting motor 74 move simultaneously. First, the driving motor 72 will drive the reciprocating screw rod 71 to rotate, so that the cutting blade 3 moves from one end of the reciprocating screw rod 71 to the other end, and at this time, the cutting motor 74 will drive the cutting blade 3 to rotate, thereby achieving the cutting of the plate. The process is used to divide the large silicon nitride plate into smaller volumes for transportation and construction needs, and through the effective cooperation between the transmission motor, the drive motor 72 and the cutting motor 74, the continuous cutting of the large silicon nitride plate is achieved, which effectively improves the cutting effect. When the cutting blade 3 rotates, the push flow blade 81 will also rotate, so as to push the airflow in the air guide box 8 into the air guide hole 82, and make the output ends of the air guide holes 82 on both sides generate airflow blowing, so as to effectively reduce the friction and high temperature generated on the surface of the cutting blade 3 during cutting, realize the protection of the cutting blade 3, and improve the durability of the cutting blade 3. The bottom of the cutting table 1 is fixedly connected with a collecting groove 83, and the collecting groove 83 is located below the cutting blade 3, and the cutting blade 3 slides along the central axis of the collecting groove 83, and the airflow blowing downwardly will push the debris generated during cutting into the collecting groove 83, so as to avoid the splashing of debris and improve the cleanliness in the cutting area.
