Description

[0001] The invention relates to the technical field of polyester film production equipment, and more specifically to a winding device for a transparent photovoltaic backplane base film. Background Art

[0002] During the production of transparent photovoltaic backplane base film, the formed transparent photovoltaic backplane base film finally needs to be rolled up and packaged by a winding device for easy storage and transportation. The transparent photovoltaic backplane base film winding device usually needs to use a conveyor roller for conveying, but the current conveyor roller is very easy to cause the transparent photovoltaic backplane base film to deviate, wrinkle, stripe, crease and other defects due to precision problems or film tension problems during the conveying process, and even make the transparent photovoltaic backplane base film unable to stably complete the specified process or be neatly rolled up. In addition, during the rolling process, dust particles are easily adhered to the transparent photovoltaic backplane base film, causing pollution of the transparent photovoltaic backplane base film.

The specific implementation of the present invention is described in more detail below in conjunction with specific embodiments:

[0027] like Figure 1 As shown, an embodiment of the present invention provides a winding device for a transparent photovoltaic backplane base film, which is used to wind up a transparent photovoltaic backplane base film 10 along a production direction (the direction shown by the arrow in the figure), including a frame 1, a winding roller 2, a first tension adjustment component 3, an exhaust dust removal component 4, a second tension adjustment component 5, a dust removal roller component 6 and a conveying roller 7; the winding roller 2 is rotatably connected to the frame 1; the first tension adjustment component 3 is connected to the frame 1, and is arranged in front of the winding roller 2 along the production direction, and is used to adjust the tension of the transparent photovoltaic backplane base film 10; the exhaust dust removal component 4 is connected to the frame 1, and is arranged The first tension adjustment component is located in front of the first tension adjustment component 3 along the production direction, and is used to absorb dust on the transparent photovoltaic backplane base film 10; the second tension adjustment component 5 is connected to the frame 1, and is arranged in front of the exhaust dust removal component 4 along the production direction, and is used to adjust the tension of the transparent photovoltaic backplane base film 10; the dust removal roller assembly 6 is connected to the frame 1, and is arranged in front of the second tension adjustment component 5 along the production direction, and is used to absorb dust on the transparent photovoltaic backplane base film 10; the conveying roller 7 is rotatably connected to the frame 1, and is arranged in front of the dust removal roller assembly 6 along the production direction, and is used to pull and convey the transparent photovoltaic backplane base film 10.

[0028] In this embodiment, the conveying roller 7 pulls and conveys the transparent photovoltaic backplane base film 10 along the production direction, and performs the first double-sided dust removal on the transparent photovoltaic backplane base film 10 when passing through the dust removal roller assembly 6. When passing through the second tension adjustment assembly 5, the second tension adjustment assembly 5 performs tension adjustment on the transparent photovoltaic backplane base film 10 in front of the production direction. When passing through the exhaust dust removal assembly 4, the exhaust dust removal assembly 4 performs the second dust removal on the transparent photovoltaic backplane base film 10. When passing through the first tension adjustment assembly 3, the first tension adjustment assembly 3 performs the second tension adjustment on the transparent photovoltaic backplane base film 10 behind the production direction, and is finally rolled up and stored by the winding roller 2. The dust removal roller assembly 6 is used for the first dust removal of the transparent photovoltaic backplane base film 10. This dust removal can effectively remove most of the dust on the transparent photovoltaic backplane base film 10. Since the first tension adjustment assembly 3 and the second tension adjustment assembly 5 are arranged on the front and rear sides of the exhaust dust removal assembly 4, the transparent photovoltaic backplane base film 10 passing through the exhaust dust removal assembly 4 can be tensioned to make it fully open to avoid wrinkles, so that the dust on the transparent photovoltaic backplane base film 10 can be effectively adsorbed by the exhaust dust removal assembly 4. After two dust removals, it can be basically guaranteed that there will be no dust on the transparent photovoltaic backplane base film 10.

When the first cylinder 32 is extended, it can push the first connecting rod 31 to move, thereby causing the first pressure roller 33 to move, thereby achieving the extrusion of the transparent photovoltaic backsheet base film 10, so as to increase the tension of the transparent photovoltaic backsheet base film 10, so that it can be fully unfolded under the action of tension.

[0030] like Figure 2 As shown, as one of the optional implementations of this embodiment, the winding roller 2 includes a winding roller body 21, a winding motor 22, a rotating shaft 23 and a baffle 24. The baffles 24 are provided at both ends of the winding roller body 21. The rotating shaft 23 is connected to the winding roller body 21 and passes through the baffle 24 to connect to the output shaft of the winding motor 22. The baffles 24 are provided at both ends of the winding roller body 21. The baffles 24 are used to limit the polyester film 10 to prevent the polyester film 10 from deflecting in the axial direction of the winding roller body 21 during the winding process.

[0031] As one of the optional implementations of this embodiment, the winding roller 2 further includes a fastener, which fastens and connects the baffle 24 and the winding roller body 21.

When the second cylinder 52 is extended, it can push the second connecting rod 51 to move, thereby causing the second pressure roller 53 to move, thereby achieving the extrusion of the transparent photovoltaic backsheet base film 10, so as to increase the tension of the transparent photovoltaic backsheet base film 10, so that it can be fully unfolded under the action of tension.

[0033] As one of the optional implementations of this embodiment, the exhaust dust removal assembly 4 includes a first box 41, a first exhaust fan (not shown), a second box 41 and a second exhaust fan (not shown), the first box 41 and the second box 42 are arranged opposite to each other, the exhaust port of the first box 41 faces one side surface of the transparent photovoltaic backplane base film 10, and the exhaust port of the second box 42 faces the other side surface of the transparent photovoltaic backplane base film 10, the first exhaust fan is connected to the first box 41 through a pipeline, and the second exhaust fan is connected to the second box 42 through a pipeline. Specifically, the first exhaust fan exhausts air, so that a negative pressure environment is generated in the first box 41, and dust on the surface of the transparent photovoltaic backplane base film 10 is adsorbed under the action of airflow. The second exhaust fan exhausts air, so that a negative pressure environment is generated in the second box 42, and dust on the surface of the transparent photovoltaic backplane base film 10 is adsorbed under the action of airflow.

Specifically, the first guide roller 8 and the second guide roller 9 pull the transparent photovoltaic backplane base film 10 at the exhaust dust removal component 4 to a horizontal setting, so that the transparent photovoltaic backplane base film 10 at the exhaust dust removal component 4 is unfolded along the horizontal plane. After unfolding, most of the area of ​​the transparent photovoltaic backplane base film 10 is covered by the exhaust dust removal component 4, which can effectively improve the efficiency of dust removal. At the same time, since the transparent photovoltaic backplane base film 10 is arranged horizontally, the dust particles on its lower surface are more easily detached from its surface under the action of gravity, thereby improving the dust removal effect.

[0035] As one of the optional implementations of this embodiment, the dust removal roller assembly 6 includes a first dust removal rubber roller 61, a second dust removal rubber roller 62, a first dust collection paper roll 63, and a second dust collection paper roll 64.

The dust collection paper on the first dust collection paper roll 63 is connected to the first dust removal rubber roller 61, and the dust collection paper on the second dust collection paper roll 64 is connected to the second dust removal rubber roller 62.
