When the cutting head 14 cuts the plate, the three-dimensional movement of the cutting head 14 can be realized through the cooperation of the first linear motor 11, the second linear motor 12 and the electric push rod 13, so as to cut different positions of the plate. When cutting, the air pump 15 is started to drive the airflow from the air inlet pipe 17 into the filter box 16. At this time, the airflow will pass through the cutting position and bring the generated smoke into the filter box 16. At this time, the activated carbon placed in the filter box 16 can filter the smoke, and the filtered gas is discharged from the air pump 15. Through the above structure, the air pump 15 is set to connect the filter box 16 and the air inlet pipe 17. During cutting, air can be exhausted from the cutting position, and the smoke generated during cutting is sucked away by the action of exhaust, and the smoke is filtered out in the filter box 16 to reduce the pollution caused by more smoke generated during cutting.

[0026] like Figure 5 As shown, the end of the air inlet pipe 17 is connected to the air guide pipe 2; the side wall of the air guide pipe 2 is connected to the air guide cover 21; during operation, when the cutting position is evacuated, when the airflow enters the air inlet pipe 17, the air guide pipe 2 can divert the airflow, so that the airflow passes through the air guide pipe 2 and enters the air inlet pipe 17, and then converges and enters the filter box 16. At this time, the air guide pipe 2 can increase the air extraction range of the air inlet pipe 17, and the air guide cover 21 is an expanded structure, which can increase the air extraction range of the air guide pipe 2.

When one side of the plate is cut, the first motor 3 can be started to drive the fixing frame 31 to rotate, and the plate can be turned over, and then the cutting head 14 is used to cut the other side. Through the above structure, the first motor 3 is set to connect the fixing frame 31, and the spring rod 33 is used in combination, so that the plate can be turned over during cutting, so as to improve the convenience during cutting and reduce the need to disassemble the plate, turn it over and re-fix it, resulting in cumbersome operation.

[0028] like Figure 3 As shown, the connection assembly includes a fixed box 4; the fixed box 4 is fixedly connected to the top of the base 1; a second motor 41 is fixedly connected to the bottom of the inner wall of the fixed box 4; a fixed plate 42 is fixedly connected to the output end of the second motor 41; a pair of support plates 43 are fixedly connected to the side wall of the fixed plate 42; the first motor 3 is fixedly connected to the inner wall of the support plate 43; during operation, when the current plate is cut at one of the fixed frames 31, another plate to be cut is placed on the other fixed frame 31, and after the current plate is cut, the second motor 41 is started to drive the fixed plate 42 and the support plate 43 to rotate, at this time, the fixed frame 31 and the plate can be driven to rotate, so that the current cut plate and the plate to be cut are exchanged with each other, and then the cutting head 14 continues to cut the new plate, and the cut plate can be removed at the same time, and then a new plate can be placed for continuous processing. Through the above structure, the second motor 41, the fixed plate 42 and the support plate 43 are set, and the plate to be cut and the cut plate are exchanged to achieve continuous processing of the plate, so as to improve the continuity and convenience during processing.

[0029] like Figure 3 As shown, a collecting box 5 is fixedly connected to the top of the base 1; the collecting box 5 is arranged at the bottom of the fixed frame 31; during operation, the waste generated during cutting will fall from the plate, and the collecting box 5 is located at the bottom of the plate at the cutting position at this time, and the fallen waste can be collected. Through the above structure, the collecting box 5 can be arranged to collect the waste generated during cutting, so as to reduce the waste from being scattered on the top of the base 1 when it falls, causing inconvenience in cleaning and dirt.

[0030] like Figure 1As shown, a baffle 6 is fixedly connected to the top of the base 1; the baffle 6 is a U-shaped structure; during operation, when the cutting head 14 is cutting, a strong light beam will be generated, and the baffle 6 can block the generated strong light.

Through the above structure, the rubber pad 7 is arranged to connect the spring rod 33, which can reduce the damage caused by squeezing the plate when the spring rod 33 clamps and fixes the plate, and at the same time can increase the friction between the spring rod 33 and the plate, reducing the sliding of the plate.

[0032] Working principle: Starting the first linear motor 11 can drive the second linear motor 12 to move horizontally forward and backward, starting the second linear motor 12 can drive the electric push rod 13 to move horizontally left and right, and starting the electric push rod 13 can drive the cutting head 14 to move vertically up and down. When the cutting head 14 cuts the plate, the first linear motor 11 cooperates with the second linear motor 12 and the electric push rod 13 to achieve three-dimensional movement of the cutting head 14, so as to cut different positions of the plate. When cutting, starting the air pump 15 drives the air flow from the air inlet pipe 17 into the filter box 16. At this time, the air flow will pass through the cutting position The generated smoke and dust are brought into the filter box 16. At this time, the activated carbon placed in the filter box 16 can filter the smoke and dust, and the filtered gas is discharged from the air pump 15. When the cutting position is evacuated, when the airflow enters the air intake pipe 17, the air guide pipe 2 can divert the airflow, so that the airflow passes through the air guide pipe 2 and enters the air intake pipe 17, and then merges and enters the filter box 16.

When cutting, pull the spring rod 33 to keep its end away from the fixed frame 31 , and then place the plate on the fixed frame 31, and then release the spring rod 33 so that its end is in contact with the surface of the plate, the plate can be clamped and fixed, and then the cutting head 14 can cut the plate. When one side of the plate is cut, the first motor 3 can be started to drive the fixed frame 31 to rotate, the plate can be turned over, and then the cutting head 14 can be used to cut the other side. When the current plate is cut at one of the fixed frames 31, another plate to be cut is placed on the other fixed frame 31. After the current plate is cut, the second motor 41 is started to drive the fixed plate 42 and the support plate 43 to rotate. At this time, The fixed frame 31 and the plate are driven to rotate, so that the plate currently being cut and the plate to be cut are exchanged with each other, and then the cutting head 14 continues to cut the new plate. At the same time, the plate that has been cut can be removed, and then a new plate can be placed for continuous processing. The waste generated during cutting will fall from the plate. At this time, the collection box 5 is located at the bottom of the plate at the cutting position, and the fallen waste can be collected. When the cutting head 14 is cutting, a strong light beam will be generated. At this time, the baffle 6 can block the strong light generated. When the spring rod 33 clamps and fixes the plate, the rubber pad 7 will contact the surface of the plate.
