The bottom of the cavity 4-1 is provided with an inclined air outlet 4-3, and the air outlet end of the air outlet 4-3 is set to a long strip shape. When in use, the electrostatic fan 4-2 is started to blow air, so that the wind enters the cavity 4-1 and is discharged from the air outlet 4-3. By starting two groups of electrostatic blowing assemblies 4, the upper and lower surfaces of the film are subjected to the first electrostatic treatment, thereby ensuring the electrostatic treatment effect on the film.
