The inlet side of the upper dust cover 11 is provided with an air nozzle 10 and an air pipe 9 for blowing the residues that fall into the upper dust cover 11 to the outlet of the upper dust cover 11. A suction pipe 12 is provided at the outlet of the upper dust cover 11 for sucking out residue. The upper dust cover 11 is rectangular in shape, and the top surface of the upper dust cover 11 has an upper felt mounting hole. During operation, the upper felt 5 passes through the upper felt mounting hole and is pressed against the outer edge of the upper cutter disc.

[0024] The lower cleaning mechanism is similar in structure to the upper cleaning mechanism, including a lower felt for cleaning the lower cutter head blades and a lower dust cover 21 for collecting residue that falls off the lower felt during cleaning. The lower dust cover 21 is 400mm long, 170mm wide, and 75mm high. The lower felt is connected to the housing 1 via a clamping mechanism for pressing the lower felt against the blades. The clamping mechanism includes a rotating shaft 2 connected to the housing 1, a rotating shaft sleeve 3 rotating on the rotating shaft 2, and a tension spring 4 for pulling the rotating shaft sleeve 3 to rotate so that the lower felt is pressed against the blades. The lower felt is connected to the rotating shaft sleeve 3 via a connecting rod. A second connecting rod is provided on the rotating shaft sleeve 3, and one end of the tension spring 4 is connected to the housing 1, and the other end is connected to the connecting rod. An air nozzle and an air pipe are provided on the inlet side of the lower dust cover for blowing residue that falls into the lower dust cover to the outlet of the lower dust cover. A suction pipe is provided at the outlet of the lower dust cover to remove residue. The lower dust cover is rectangular in shape, and the bottom surface of the lower dust cover has a lower felt mounting hole. During operation, the lower felt passes through the lower felt mounting hole and is pressed against the cutting edge of the inner side of the lower cutter disc.

[0025] Cutter shaft clearance openings are provided on the front and bottom surfaces of the upper dust cover 11. The edge of the opening on the front surface of the upper dust cover 11 is arc-shaped 1101, and the diameter of the arc 1101 is 1 mm larger than the outer diameter of the upper cutter pad 15. The edge of the opening on the bottom surface of the upper dust cover 11 is convex in shape. Cutter shaft clearance openings are provided on the front and top surfaces of the lower dust cover. The edge of the opening on the front surface of the lower dust cover is arc-shaped, and the diameter of the arc 1101 is 1 mm larger than the outer diameter of the lower cutter disc 19. The edge of the opening on the top surface of the lower dust cover is convex in shape.

[0026] The housing 1 is equipped with a needle valve type oil cup 8 and an oil delivery pipe 6 for conveying the cleaning oil in the oil cup 8 to the upper felt and the lower felt respectively. The oil cup 8 is mounted on the upper part of the housing 1 via an oil cup bracket 7.

[0027] When installing the upper cleaning mechanism, first drill threaded holes at suitable positions on the disc scissor box 1. Install the rotating shaft 2 first, then fix the rotating shaft sleeve 3 to the rotating shaft with nuts. Connect a tension spring 4 to one end of the rotating shaft sleeve and an upper felt 5 to the other end. One side of the upper felt 5 is connected to the oil supply pipe 6, and the other side contacts the outer edge of the upper cutter disc. Drill holes on the side of the cutter box 1 to install the oil cup bracket 7. Install two needle valve type oil cups 8 on the oil cup bracket 7. Fix the upper dust cover 11 above the blade with screws. Install an air pipe 9 and an air nozzle 10 on the inlet side of the upper dust cover 11, and install a suction pipe 12 on the outlet side. A vacuum cleaner is connected to the outer end of the suction pipe 12. The lower cleaning mechanism is installed in the same way.

[0028] During normal operation, cleaning oil is injected into the upper cleaning mechanism via the needle valve-type oil cup 8 and flows into the upper felt 5 through the oil supply pipe 6, thus immersing the upper felt 5 in cleaning oil. The upper felt 5 is installed on one side of the rotating shaft sleeve 3, which rotates around the rotating shaft 2. The other side of the rotating shaft sleeve 3 is connected to a tension spring 4, which is fixed to the tool box. The tension spring 4 generates tension through deformation, causing the rotating shaft sleeve 3 to rotate and contact the upper felt 5 with the cutting edge of the upper tool disc. When the cutting edge contacts the upper felt 5 during operation, it can clean the residue at the cutting edge. The residue falls through the upper felt 5 into the upper dust cover 11. The upper dust cover 11's inlet side is blown to the outlet side by the air nozzle 10. The upper felt 5 also cools the cutting edge. The suction pipe 12 on the outlet side of the upper dust cover 11 sucks the blown residue out of the upper dust cover 11. The lower cleaning mechanism operates in the same way as the upper cleaning mechanism.
