[0033] Initially, the air intake pipe 12 is connected to an external air pump, and a piece of plate material is first placed between the porous support cylinders 11, and then the front and rear electric shafts 165 are started to rotate, and the rotation of the electric shaft 165 drives the front and rear winding wheels 166 to rotate, and the rotation of the winding wheels 166 reels the pull wire 167, and the reeling of the pull wire 167 drives the outer end of the elastic hinge frame 163 to swing, and the torsion spring of the elastic hinge frame 163 is compressed, so that the elastic hinge frame 163 stretches and drives the front and rear waist-shaped hole plates 164 to move in a direction close to each other, and the waist-shaped hole plates 164 drive the front and rear positioning plates 161 to move in a direction close to each other, and the front and rear positioning plates 161 contact with the plate material, and the front and rear positioning plates 161 center the plate material, so that the plate material is parallel to the vertical plate 21. state to prevent the plate material from being in an inclined state and affecting the cutting accuracy, thereby ensuring the cutting accuracy of the plate material, turn off the electric rotating shaft 165, the winding wheel 166 stops continuing to reel in the pulling wire 167, and the front and rear positioning plates 161 stop moving, then start the sensor 162 and the driving motor 6, the driving motor 6 drives the hollow cylinder 5 to rotate, the hollow cylinder 5 drives the contact rod 155 to rotate, the contact rod 155 rotates through the n-shaped groove 152 to drive the circular saw blade 4 to rotate, and then start the external air pump to blow air into the air intake pipe 12, the air in the air intake pipe 12 is discharged into the air guide pipe 10, the air in the air guide pipe 10 is discharged into the porous support tube 11, the porous support tube 11 sprays the air, the air is sprayed on the porous support tube 11 and the air guide pipe 10, and the air is in the porous support The outer wall of the support tube 11 and the outer wall of the air guide tube 10 form an airflow barrier. The stepper motor 9 is started to rotate forward to drive the conveying roller 7 to rotate forward. The conveying roller 7 rotates forward to drive the conveyor belt 8 to rotate forward, and the three-axis moving machine 2 is started to drive the electric rotating seat 3 to move. The electric rotating seat 3 moves through the hollow tube 5 to drive the circular saw blade 4 to move. At the same time, the movement of the three-axis moving machine 2 drives the movable frame 1401 to move. The movement of the movable frame 1401 drives the electromagnet 14 to move. The electromagnet 14 is started. When the electromagnet 14 moves to the bottom of the iron block 143, the electromagnet 14 attracts the iron block 143 downward through magnetic force. The iron block 143 is in magnetic contact with the electromagnet 14. The iron block 143 moves downward, driving the porous support tube 11 to move downward. The compression spring 142 is compressed, and the porous support tube 11 moves downward. The circular saw blade 4 moves forward and backward to avoid the position. When the electromagnet 14 continues to move and loses contact with the iron block 143, due to the action of the compression spring 142, the porous support cylinder 11 moves upward and resets, driving the iron block 143 to move upward and reset. When the circular saw blade 4 moves to the position for cutting the plate material, the three-axis moving machine 2 is turned off, and the electromagnet 14 stops moving. At this time, a row of iron blocks 143 corresponding to the electromagnet 14 are sucked downward by the electromagnet 14, which makes the porous support cylinder 11 move downward and lose contact with the plate material to avoid it, which does not affect the forward and backward movement of the circular saw blade 4 to cut the plate material, and the angle of the circular saw blade 4 can be adjusted by starting the electric rotating seat 3 to rotate, so that the circular saw blade 4 can be adjusted to the required angle for cutting according to needs.The three-axis moving machine 2 is restarted to drive the electric rotating seat 3 to move downward, so that the circular saw blade 4 moves downward to contact the plate material for cutting, and the electric rotating seat 3 moves downward to drive the sensor 162 to move downward to correspond to the positioning plate 161. The debris generated during the cutting process falls downward and contacts the formed airflow barrier. The airflow barrier can blow away the fallen debris to prevent the air duct 10 and the porous support tube 11 from being attached with debris and affecting subsequent use, thereby ensuring the normal use of the air duct 10 and the porous support tube 11. The blown debris falls onto the conveyor belt 8, and the conveyor belt 8 rotates forward to drive the debris to the right. The debris moves and falls onto the inclined plate 13, and the inclined plate 13 guides the debris. The guided debris falls from the inclined plate 13 and is collected. In this way, it can prevent the debris residue in the cutting process from causing the subsequent manual cleaning to take time, thereby improving the efficiency of cutting the plate material. Then the three-axis mobile machine 2 continues to operate to drive the electric rotating seat 3 to move back and forth, and the electric rotating seat 3 drives the sensor 162 and the hollow cylinder 5 to move back and forth. The hollow cylinder 5 moves back and forth to drive the circular saw blade 4 to move back and forth to cut the plate material. The sensor 162 moves continuously close to the corresponding positioning plate 161, and the sensor 16 2 and the positioning plate 161 reaches the set value, the sensor 162 controls the electric shaft 165 to rotate in the opposite direction through the control module, the electric shaft 165 rotates in the opposite direction to drive the winding wheel 166 to rotate in the opposite direction, the pull wire 167 is loosened, due to the torsion spring of the elastic hinge frame 163, the elastic hinge frame 163 swings and resets to drive the waist-shaped hole plate 164 to move outward and reset, the waist-shaped hole plate 164 resets and drives the positioning plate 161 to move outward and reset, the positioning plate 161 resets and breaks away from the contact with the plate material to avoid, so as to prevent the corresponding positioning plate 161 from affecting the cutting of the plate material by the circular saw blade 4, The remaining three positioning plates 161 continue to position the board material. When the board material is cut once, the electric rotating seat 3 drives the circular saw blade 4 and the sensor 162 to move to the middle and reset through the hollow cylinder 5. The distance between the sensor 162 and the positioning plate 161 does not match the set value. The sensor 162 controls the electric rotating shaft 165 to rotate through the control module to drive the winding wheel 166 to rotate and reset, which makes the positioning plate 161 move and reset again to contact the board material for positioning. This is repeated to continuously cut the board material and make the board material cut into the required size. When the cutting of the plate material is completed, the electromagnet 14 is turned off, and the three-axis moving machine 2 is started to drive the electric rotating seat 3 to move rightward and reset, so that the circular saw blade 4 and the electromagnet 14 are moved rightward and reset, and the electromagnet 14 is reset and contacts the scraper 141, and the scraper 141 scrapes the debris remaining on the electromagnet 14, and the scraped debris falls to the conveyor belt 8 to be transported and removed, and then the drive motor 6 is turned off, the circular saw blade 4 stops rotating, and then the electric rotating shaft 165 is started to rotate in the opposite direction so that the pull wire 167 is relaxed, and the elastic hinge frame 163 drives the front and rear positioning plates 161 to move away from each other and reset through the waist-shaped hole plate 164.The positioning plate 161 is reset to be out of contact with the plate material, and then the cut plate material is removed for subsequent processing, the stepper motor 9 is turned off, the conveyor roller 7 stops driving the conveyor belt 8 to rotate forward, and the external air pump is turned off at the same time, the air stops being discharged into the air inlet pipe 12, and the porous support tube 11 also stops spraying air; Switching of the circular saw blade 4: initially, four of the strong magnets 151 have four circular saw blades 4 of different types magnetically attracted thereto. When different types of circular saw blades 4 are needed for cutting, the three-axis moving machine 2 is first started to drive the electric rotating seat 3 to move forward and backward. The electric rotating seat 3 drives the circular saw blade 4 to move forward and backward through the hollow cylinder 5. When the circular saw blade 4 moves forward and backward to correspond to the strong magnet 151 to which the circular saw blade 4 is not magnetically attracted, the three-axis moving machine 2 is closed, the electric telescopic frame 15 is started to move rightward to drive the strong magnet 151 to move rightward. When the strong magnet 151 to which the circular saw blade 4 is not magnetically attracted moves rightward and contacts the left end of the circular saw blade 4 on the hollow cylinder 5, the strong magnet 151 attracts the circular saw blade 4 on the hollow cylinder 5 through magnetic force, and the strong magnet 151 continues to move rightward to drive the circular saw blade 4 to The circular saw blade 4 moves right, drives the n-type slot 152 and the six-pointed rod 153 to move right, and the connecting spring 154 is compressed. When the n-type slot 152 moves to the right so that the leftmost side contacts the contact rod 155, the electric telescopic frame 15 is closed, and the driving motor 6 is started again to drive the hollow cylinder 5 to rotate forward. The forward rotation of the hollow cylinder 5 drives the contact rod 155 to rotate forward. When the contact rod 155 rotates forward to the other side of the n-type slot 152, the driving motor 6 is turned off, and the hollow cylinder 5 stops driving the contact rod 155 to rotate forward. Then the electric telescopic frame 15 is started to move left, driving the strong magnet 151 to move left. The strong magnet 151 moves left and drives the circular saw blade 4 to move left. The circular saw blade 4 moves left and drives the n-type slot 152 to move left. The n-type slot 152 is out of contact with the contact rod 155, and the circular saw blade 4 Move left and disengage from the six-pointed rod 153.
