DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1 As shown, the electrostatic dust removal mechanism for the heat shrink film in this embodiment includes a frame 1, a feeding roller 2, a winding roller 3, a driving motor 4, an electrostatic elimination component 5, a negative pressure fan 6 and a dust removal box 7. The feeding roller 2 and the winding roller 3 are respectively supported and arranged at the upper ends of the frame 1, the driving motor 4 is connected to the winding roller 3 by transmission, the electrostatic elimination component 5 is arranged above the frame 1 and is located between the feeding roller 2 and the winding roller 3, and a guide roller 8 is provided on each side of the electrostatic elimination component 5.

[0017] The heat shrinkable film coil to be dusted is set on the feeding roller 2, and the heat shrinkable film is wound onto the winding roller 3 through two guide rollers 8 and the static elimination component 5. Driven by the driving motor 4, the heat shrinkable film on the feeding roller 2 is wound onto the winding roller 3.

[0018] The negative pressure fan 6 is arranged at the bottom of the static elimination component 5, the dust removal box 7 is arranged on the frame 1 and connected to the negative pressure fan 6 through the pipe 9, and a pull-out dust collection drawer 71 is provided in the dust removal box 7. When the dust in the dust removal box 7 is full, the dust collection drawer 71 can be pulled out for cleaning.

[0019] like Figure 2 As shown, the static elimination component 5 includes a sealed shell 51, a dust removal chamber 52 is provided on the upper part of the sealed shell 51, a dust removal rod 53 is provided on the upper and lower sides of the dust removal chamber 52, a dust removal plate 54 is provided on the opposite side of the two dust removal rods 53, and a plurality of dust removal holes 55 are provided on the dust removal plate 54, and a film inlet 56 and a film outlet 57 are provided on the front and rear sides of the sealed shell 51, respectively, and the film inlet 56 and the film outlet 57 are both connected to the dust removal chamber 52.

[0020] Negative pressure channels 58 are provided on both side walls of the sealed shell 51 , a suction port 59 is provided at the bottom of the negative pressure channel 58 , and an air inlet 510 is provided at the top. The suction port 59 is connected to the negative pressure fan 6 , and the air inlet 510 is connected to the dust removal chamber 52 .

[0021] Among them, the dust removal rod 53 can be a wind-type ion rod. When the ion rod is working, a super strong ionization field can be generated between the discharge needle and the ground level, and the air molecules are ionized to generate a large number of positive and negative charges, which can neutralize the charge on the heat shrink film. When the charge on the surface of the heat shrink film is negative, it will attract the positive charge in the airflow, and the negative charge will be repelled; when the charge on the surface of the heat shrink film is positive, it will attract the negative charge in the airflow, and the positive charge will be repelled, so that the static electricity on the surface of the heat shrink film is neutralized, achieving the purpose of eliminating static electricity.

[0022] The heat shrink film is pulled into the dust removal chamber 52 through the film inlet 56, and the dust removal rod 53 works to remove the static electricity on the surface of the heat shrink film. Since the heat shrink film surface loses static electricity, the heat shrink film no longer has adsorption force, and the negative pressure fan 6 works to suck the dust on the surface of the heat shrink film into the dust removal box 7 through the negative pressure channel 58, thereby realizing the cleaning and dust removal of the heat shrink film.
