As the toner is adhered to the surface of the toner cartridge, in order to prevent the toner from flying to pollute the environment when the surface of the toner cartridge is polished, as shown in figure 1, the upper cover 12 is additionally arranged on the upper surface of the shell, and the transparent window 13 is arranged on the upper cover 12, so that the working conditions of all components in the shell can be observed conveniently. A drawer type base 14 is additionally arranged at the lower part of the shell. The selenium drum fixing and rotating assembly 2 and the polishing assembly 3 are installed on a drawer type base 14, and a blanking port 15 is formed in the top surface of the drawer type base 14 and below the selenium drum fixing and rotating assembly 2. The air outlet of the drawer-type base 14 is provided with filter cotton for absorbing fine powdered ink. In order to prevent the powdered ink from overflowing from the gap, sealing strips are stuck around the shell and between the shell and the upper cover. Strong magnets are arranged between the base 14 and the drawer 17, so that the base 14 and the drawer 17 are tightly attached, the joint of the blanking port of the drawer 17 and the blanking port of the base 14 adopts a wedge-shaped design, and the attachment is tight without waste leakage. After the toner powder and debris have been collected, the entire drawer 17 is withdrawn and the collected waste material is dumped by opening the cover 171 or lid at the rear of the drawer.
As shown in fig. 1, the present invention further includes a control unit 18, a power plug, an indicator light, and various control keys 181 for starting, stopping, forward rotation, and reverse rotation are mounted on the surface of the power unit 18, and a power converter, a control circuit and a relay for controlling the rotation of the blade motor 22, the stepping motor 351, the grinding motor 33, and the swing arm motor 44 are mounted in the box to control the rotation or stop of the motors.
The invention has the advantages that:
