[0028] How it works

[0029] When using the internal grinder body 3 to grind the wiper, first put the wiper in the U-shaped seat 13. After adjusting the fixed position, hold the hand wheel 17 to rotate the movable bolt 16. After the movable bolt 16 rotates in the mounting nut seat 15, it drives the anti-skid clamp 18 at the other end to move toward the wiper until the anti-skid clamp 18 contacts the wiper and clamps the wiper on the anti-skid positioning pad 14, completing the rapid fixation of the wiper. When it is necessary to adjust the grinding position of the wiper, start the drive motor 7, control the output shaft of the drive motor 7 to rotate, and drive the threaded screw 28 to rotate in the mounting seat 5 through the bearing seat 8. The movable nut seat 9 is driven by the meshing of the threaded screw 28 and the limiting action of the positioning slider 10 at the lower end of the movable nut seat 9 sliding on the guide slide rail 6. The movable nut seat 9 can make linear motion in the sliding groove 12, drive the U-shaped seat 13 to move horizontally, and realize automatic adjustment of the grinding position of the wiper in the U-shaped seat 13. When the internal cylindrical grinder body 3 generates a large amount of dust when grinding the wiper, the centrifugal fan 23 is started. After the blades of the centrifugal fan 23 rotate at high speed, the interior of the ash storage box 21 will be instantly vacuumed, forming a pressure difference with the air below the suction hood 27. Under the action of the pressure difference, the suction hood 27 can suck the air containing dust below into the ash storage box 21, and the filter net 25 filters and blocks the dust and leaves it in the ash storage box 21. The filtered air is discharged through the exhaust pipe 24, completing the automatic real-time cleaning and collection of the dust generated during grinding.
