It should be noted that the flexible blocking strip 12 is made of textiles or rubber products, and its movement state is limited by the groove bottom and the groove top of the arc-shaped sliding groove, so that it can cover the width shape of the arc-shaped sliding groove.
[0023] Specifically, the vibration assembly is embedded and fixed to the fixed seat 1001 of the movable seat 6 or the moving strip 11. The outer coaxial of the center column of the fixed seat 1001 is fixed with a ring-shaped magnet 1002.

[0024] Specifically, the filtering and collecting assembly comprises a rotating shaft 20 arranged below the partition plate and rotated by a motor (not shown in the figure), a top portion of the rotating shaft 20 is coaxially fixed with a driving gear 22, a plurality of filtering bags 10 are uniformly arranged on the outer side of the rotating shaft 20 at a certain radius, top portions of the filtering bags 10 are rotatably arranged below the partition plate by a hollow shaft, a top portion of the hollow shaft is coaxially fixed with a driven gear 23, each driven gear 23 is engaged with the driving gear 22 for transmission, the top portion of the hollow shaft extends into an airflow interlayer 24 arranged in the partition plate, one side of the airflow interlayer 24 is provided with an air duct and connected with a negative pressure generating device to discharge the airflow in the collecting box 17, so that the residual floating beads are left in the collecting box 17 by the filtering bags 19, and an inner wall of the collecting box 17 is attached with a collecting film 18; in addition, the rotating shaft 20 is fixed with a plurality of poking rods 21 uniformly distributed at different heights on the outer periphery, the poking rods 21 strike and disturb the filtering bags 19 at different heights to avoid the light beads from adhering and blocking the filtering holes, and the poking rods 21 are made of soft rubber.
[0025] In use, after the anti-fake reflective film is pulled, the height position of the guide pulling wheel 2 is adjusted so that the anti-fake reflective film is between the airflow jet strip 4 and the movable seat 6, and has a film surface arc similar to the frame of the movable seat 6; the anti-fake reflective film is blown by the airflow jet strip 4 to be in an airflow suspension tension state; then the inflatable air bag 7 is inflated so that the top of the movable seat 6 is close to the reflective surface of the anti-fake reflective film to a certain distance; then the periodic alternating current in the vibration assembly 10 is turned on, the periodic alternating current generates a magnetic field in the coil 1007, the magnetic field cooperates with the magnetic field of the annular magnet 1002, so that the lightweight sleeve 1003 moves up and down at high frequency, thereby driving the metal foil 1005 to vibrate at high frequency; the vibration causes the airflow on the surface of the metal foil 1005 to vibrate at high frequency, and then acts on the film surface of the anti-fake reflective film suspended and tensioned by the airflow above; the film surface vibrates under the impact of high-frequency airflow, so that the residual floating beads that are not firmly adhered to the film surface are separated from the film surface and fall into the base 5 and the standby hopper 25 under the action of gravity and negative pressure, and then into the collecting box 17; the anti-fake reflective film is intermittently pulled at low speed during the action of high-frequency airflow, and the residual floating beads on the surface of the anti-fake reflective film are cleaned; during the cleaning process, the moving strip 11 moves back and forth at a constant speed under the cooperation of the gear and rack, and each time the moving strip 11 moves back and forth, it means that the cleaning of the film surface of the corresponding area is completed; continue to pull for a distance to clean the film surface of the subsequent area. The light beads entering the collecting box 17 are filtered and retained in the collecting box 17 or the filtering bag 19 by the filtering bag 19, and the rotating shaft 20 driven by the motor rotates to strike and disturb the filtering bag 19 at different height positions, so that the light beads adsorbed on the surface of the filtering bag 19 fall off, preventing the filter holes from being blocked, and because the filtering bag 19 is also in a rotating state, the position of each strike is different, thereby avoiding damage caused by concentrated strikes; after the anti-fake reflective film is pulled, the filtering and collecting assembly is closed in a time-delay manner, and then the collecting film 18 is packed to quickly complete the cleaning and collecting work.
