[0023] like Figure 1-3 As shown, a dust collecting device for a laser cutting dust collector includes a main body 1, an ash collecting chamber 2 is provided inside the main body 1, a filter portion 3 is rotatably provided inside the ash collecting chamber 2, the ash collecting chamber 2 and the filter portion 3 are both cylindrical structures and have the same height, and the upper and lower sides of the ash collecting chamber 2 and the filter portion 3 are both arranged close to the inner side of the main body 1.

[0024] An ash collecting space 4 is formed between the outer side of the filter part 3 and the inner side of the ash collecting chamber 2. Four partitions 5 are evenly arranged on the outer side of the filter part 3. The four partitions 5 divide the ash collecting space 4 into a first area 6, a second area 7, a third area 8 and a fourth area 9. The four areas can only be connected through the filter part 3, and the other positions of the four areas are almost in a closed state. A first motor chamber 10 is arranged above the middle of the filter part 3 inside the main body 1. A first drive motor 11 is arranged in the first motor chamber 10. The output end of the first drive motor 11 extends downward to the middle of the filter part 3 and is connected to a rotating shaft 12. A connecting rod 13 is arranged on the side of the rotating shaft 12, and the connecting rod 13 is connected to the inner side of the filter part 3. The filter part 3 and the four partitions 5 can be driven to rotate by the first drive motor 11.

[0025] An air inlet pipe 14 and an air return pipe 15 are also provided on both sides of the inner side of the main body 1 above the ash collecting chamber 2. The bottoms of the air inlet pipe 14 and the air return pipe 15 are arranged close to the top surface of the ash collecting chamber 2. After the airflow with dust enters the air inlet pipe 14, it can only be filtered by the filter unit 3 and then flow out through the air return pipe 15. The air inlet pipe 14 is used by the dust collector to suck the dust generated when the laser cutter is working. Figure 2 As shown by the arrow in , below the air inlet pipe 14 is the first area 6. The air inlet pipe 14 first transports the dust-carrying airflow generated when the laser cutter is working to the first area 6. Under the action of the airflow, it diffuses to other areas through the filter unit 3. The dust contained in the airflow is blocked by the filter unit 3, and the filter unit 3 is a circular tubular structure composed of a filter screen with a certain filtering ability. The dust is thus accumulated in the first area 6. The return air pipe 15 is above the third area 8. In addition to the third area 8, it can also be set above the second area 7 or the fourth area 9. The function of the return air pipe 15 is to promote airflow circulation. The main body 1 is located below the dust collection space 4 and is provided with a dust outlet 16. In this embodiment, the dust outlet 16 is located below the second area 7. After the dust collector has been working for a period of time, a lot of dust will accumulate inside the first area 6. At this time, the first motor is driven to drive the filter part 3 and the four partitions 5 to rotate counterclockwise by 90°, so that the first area 6 rotates to the original position of the second area 7. At this time, the dust in the first area 6 will fall to the dust outlet 16 and then be discharged from the dust outlet 16. By rotating the filter part 3 by the motor, the accumulated dust can be automatically removed regularly, and the system can achieve continuous and stable operation, which can extend the service life of the equipment, reduce the maintenance frequency, and improve the reliability and stability of the system.

[0026] After the rotation is completed, the air inlet pipe 14 first transports the dust-containing airflow generated by the laser cutter to the fourth area 9, and the fourth area 9 begins to accumulate dust. When the dust is full, the filter part 3 and the partition 5 are rotated again to complete the dust cleaning.

[0027] A negative pressure chamber 22 is provided above the main body 1, an exhaust fan 23 is provided in the negative pressure chamber 22, an air outlet 24 is provided at the top of the negative pressure chamber 22, an air inlet 25 is provided at the bottom of the negative pressure chamber 22, and the air inlet 25 is connected to the return air pipe 15. The exhaust fan 23 generates negative pressure by wind force, the air inlet pipe 14 starts to suck the airflow with dust, and the filtered airflow enters the negative pressure chamber 22 from the return air pipe 15 and is discharged. Example 2

[0028] Combination Figure 4-5 , this embodiment has the same parts as the embodiment 1, and the difference between this embodiment and the embodiment 1 is that: a cleaning pipe 17 is also connected to the main body 1, one end of the cleaning pipe 17 is connected to the cleaning air pump, and the other end of the cleaning pipe 17 passes through the main body 1 and communicates with the inner side of the filter 3. The air pump can blow air into the inner side of the filter 3, and the airflow impacts the filter 3 on both sides, which can wash away the accumulated dust on the outer side of the filter 3, thereby preventing blockage. In this embodiment, the cross section of the dust discharge port 16 is funnel-shaped, and a discharge channel 18 is provided at the bottom of the dust discharge port 16. A second motor chamber 19 is provided on the side of the discharge channel 18. A second drive motor 20 is provided in the second motor chamber 19, and the output end of the second drive motor 20 extends into the discharge channel 18 and is connected to a discharge auger 21. The discharge auger 21 is a screw conveyor, which is a machine that uses a motor to drive the screw to rotate and push the material to achieve the purpose of transportation. It is a well-known technology in the art, and the specific principle and structure of this embodiment will not be repeated.

[0029] The spiral structure of the discharge auger 21 can prevent dust from accumulating and clogging at the dust discharge port 16 . Through continuous rotation, the discharge auger 21 can smoothly push the dust to the downstream processing system, thus avoiding the possible clogging problem of the dust discharge port 16 .

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
