[0033] As Figures 1-5As shown, in this embodiment, there are two static eliminators 3, which are located on the upper and lower sides of the discharge port 12, respectively. Each static eliminator 3 includes a static eliminator rod 31, which is attached to the upper and lower sides of the plastic seal film to perform static elimination treatment on the upper and lower sides of the plastic seal film. To avoid mutual interference between the two static eliminators 31, the two static eliminators 31 are staggered and can slide up and down relative to the dust collection box 1. Specifically, the static eliminators 31 are fixedly installed on the support plate 32, which is connected to the sliding plate 33 by an elastic connector. The sliding plate 33 is slidably connected to the side wall of the dust collection box 1.

[0034] like Figures 1-5 As shown, in this embodiment, the elastic connector includes a guide rod 341 and a spring 342. The guide rod 341 is fixedly installed on the side of the support plate 32 away from the antistatic rod 31. The spring 342 is sleeved on the guide rod 341.
