[0017] The following is combined with Figure 1-4 This application is described in further detail.

[0018] The present application discloses a double-sided dust removal mechanism for photovoltaic thin film printing, referring to Figure 1-4, including a roller frame 1, on which are mounted several guide rollers, the guide rollers including a right-side feeding guide roller, a right-side bottom guide roller, a left-side bottom receiving guide roller, a left-side top supporting guide roller and a left-side bottom discharging guide roller. The arrangement of these guide rollers allows a certain amount of photovoltaic film to be stored in the roller frame 1 for subsequent printing and feeding. The roller frame 1 is also provided with a plurality of dust removal components 2, which are respectively arranged on both sides of the photovoltaic film. There are two dust removal components 2, which are respectively arranged on both sides of the photovoltaic film for dust removal on the front and back of the photovoltaic film. The dust removal component 2 includes a sticky roller 21, an expansion shaft 22, a dust collecting roll 23 and a bracket module. The bracket modules are symmetrically arranged at both ends of the sticky roller 21. The frame module includes a support frame 24, a mounting plate 25, a cylinder 26 and a support plate 27. The support frame 24 is fixed on the roller frame 1, the mounting plate 25 is fixed on the support frame 24, the sticky roller 21 is rotatably connected to the mounting plate 25, the sticky roller 21 is a silicone sticky roller 21, the cylinder 26 is fixed on the mounting plate 25, the output end of the cylinder 26 is fixed with a connecting plate 28, the support plate 27 is fixed on the connecting plate 28, and a card slot 271 with an upward opening is provided on the support plate 27. A bearing is installed at the end of the expansion shaft 22, and the bearing is matched and arranged in the card slot 271. The dust collecting roll 23 is sleeved on the expansion shaft 22, and the cylinder 26 is used to drive the dust collecting roll 23 to fit the sticky roller 21. Multiple sticky rollers 21 can be respectively fitted on both sides of the photovoltaic film.

[0019] Reference Figure 4 In order to make the dust collecting roll 23 fit tightly with the dust sticking roller 21, a guide groove 261 is opened on the cylinder body of the cylinder 26, and a guide block matching the guide groove 261 is fixed on the support plate 27 at the position corresponding to the guide groove 261.

[0020] Reference Figure 1 and Figure 2 The two sides of the roller frame 1 are retaining walls, and a double door 3 is installed on the surface of the retaining wall. The staff can open the double door 3 to peel off the dust collecting roll 23 in the dust removal assembly 2 on the inner side of the photovoltaic film.

[0021] The implementation principle of a double-sided dust removal mechanism for photovoltaic thin film printing in the embodiment of the present application is as follows:

[0022] The photovoltaic film is fed from the right feeding guide roller and discharged from the left bottom discharging guide roller. During this process, the photovoltaic film is supported by the right bottom guide roller, the left bottom receiving guide roller and the left top support guide roller, so that a certain amount of photovoltaic film can be stored in the roller frame 1 and the photovoltaic film can be tightened. The two dust removal components 2 are respectively arranged on both sides of the tightened photovoltaic film. The sticky roller 21 is always attached to the photovoltaic film. The photovoltaic film drives the sticky roller 21 to rotate, and the dust on the surface of the photovoltaic film will be sticky roller 21. After the sticky roller 21 adheres for a period of time, the cylinder 26 pulls the dust collecting roll 23 tightly against the sticky roller 21, and the dust on the sticky roller 21 can be sticky roller 23. After the dust collecting roll 23 adheres for a period of time, the cylinder 26 drives it away from the sticky roller 21. At this time, the staff can remove a layer of the surface of the dust collecting roll 23 for reuse.

[0023] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
