Detailed Implementation The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0009] like Figure 1-3 As shown, a dust removal device for the surface of a mechanical pencil lead processing unit includes a body 1. The body 1 has a hopper 2, a channel 3, and a dust collection hood 4. The hopper 2 is located in the middle of the body 1, and a support frame 5 is fixed to the hopper 2 at a 15° angle by screws. Connecting screws 6 are welded at equal intervals to the bottom of the support frame 5. An ultrasonic transducer 7 is threaded to the lower end of the connecting screws 6. Ultrasonic adhesive is applied between the top of the ultrasonic transducer 7 and the bottom of the support frame 5. The channel 3 is located in the middle of the top of the body 1. The dust collection hood 4 is fixed to the top of the body 1 by screws. A cyclone separator 8 is placed on the right side of the body 1. The inlet pipe of the cyclone separator 8 is connected to the dust collection hood 4. The exhaust pipe of the cyclone separator 8 is connected to a first solenoid valve 9 via a flange. A connecting pipe 10 is connected to the end of the first solenoid valve 9 via a flange. A pulse dust collector 11 is connected to the end of the connecting pipe 10 via a flange. A second solenoid valve 12 is connected to the bottom outlet of the pulse dust collector 11 via a flange. A recycling box 13 is connected to the end of the second solenoid valve 12 via a flange. Specific usage: Connect the ultrasonic transducer 7 to the external ultrasonic generator via wires, and connect the first solenoid valve 9, pulse dust collector 11, and second solenoid valve 12 to the external PLC control cabinet via wires. When performing dust removal on pencil leads, start the ultrasonic transducer 7, place the pencil lead on the material rack 5, and simultaneously start the pulse dust collector 11. At this time, the dust on the pencil lead is peeled off under the amplitude of the ultrasonic waves. The negative pressure suction generated by the pulse dust collector 11 draws the dust into the cyclone separator 8 through the dust collection hood 4 for separation. After separation, the fine particles of raw material dust are drawn onto the filter bags inside the pulse dust collector 11. After the pulse dust collector 11 has been working for a period of time, the first solenoid valve 9 closes and the second solenoid valve 12 opens. At this time, the pulse dust collector 11 starts pulse jet cleaning, which back-blowing and peeling off the fine particles of dust on the filter bags inside the pulse dust collector 11, causing them to settle into the recovery box 13.
