The dust suction fan 23 is used to reduce the internal air pressure of the dust box 2 when it rotates, so that the external air quickly enters from the air inlet slot 16, so that the metal dust in the electrostatic adsorption wheel structure 4 that is moved and raised by the metal dust removal rod 9 will be quickly absorbed into the dust box 2.

[0031] like Figure 1-Figure 4 As shown, the principle of the metal dust capture filter provided in this embodiment is as follows: when using the device, a suitable second rotating wheel 6 should be selected first, and then one end of the second rotating wheel 6 should be fixed to the first connecting shaft 12 at the output end of the second motor 11 by bolts, and then the other end of one end of the second rotating wheel 6 should be fixed to the second connecting shaft 15 on the dust box 2 corresponding to the position of the first connecting shaft 12 by bolts; a suitable first rotating wheel 5 should be selected, and one end of the first rotating wheel 5 should be fixed to the first connecting shaft 12 at the output end of the first motor 10 by bolts, and then the other end of one end of the first rotating wheel 5 should be fixed to the second connecting shaft 15 on the dust box 2 corresponding to the position of the first connecting shaft 12 by bolts, and then an air intake baffle 7 should be embedded under the second rotating wheel 6 and fixed to the dust box 2 by bolts, and then another air intake baffle 7 should be embedded above the first rotating wheel 5 and fixed to the dust box 2 by bolts; open the sealing door 18 and put the recovery box 19 into the dust box 2, and then the filter plate 24 should be embedded and installed and the sealing door 18 should be closed;

[0032] The uncut diaphragms are rolled together, and a cutting device is used to pull out and cut the diaphragm roll. The device needs to be installed in front of the cutting device to allow the diaphragm to be cut to pass through the device and remove metal dust from the surface of the diaphragm.

[0033] When the diaphragm passes through the electrostatic adsorption wheel structure 4, the first motor 10 and the second motor 11 will respectively drive the first rotating wheel 5 and the second rotating wheel 7 to rotate along the movement direction of the diaphragm. The rotation directions of the first rotating wheel 5 and the second rotating wheel 7 are always opposite. The first rotating wheel 5 and the second rotating wheel 7 will rotate to make the metal dust capturing brushes 8 on themselves clean the front and back sides of the diaphragm. At this time, the metal dust will be electrostatically adsorbed on the first rotating wheel 5 and the second rotating wheel 7 through the metal dust capturing brushes 8; the first rotating wheel 5 and the second rotating wheel 7 that are respectively rotated into the air intake baffle 7 will be moved by the metal dust removing rod 9 so that the metal dust is removed from the metal dust capturing brush 8. The metal dust sucked into the dust box 2 will be blocked by the filter plate 24; if it is found that the suction force of the device is not enough to absorb the metal dust, the device can be turned off and the sealing door 18 can be opened. When the dust suction fan 23 stops rotating, the metal dust on the filter plate 24 will fall into the recovery box 19. A small amount of attached metal dust can be knocked on the filter plate 24 to fall into the recovery box 19. The user can take out the recovery box 19, put in a new recovery box 19 and close the sealing door 18 to start the operation.
