Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic adhesive film production, and more specifically to a dust removal mechanism for photovoltaic adhesive film winding. Background Art

[0002] Photovoltaic film materials are usually ethylene-vinyl acetate copolymer (EVA) films, which are used to wrap and encapsulate both sides of photovoltaic cells in photovoltaic panels, so that the whole is located between photovoltaic glass and photovoltaic backplane, thereby increasing the service life of the entire photovoltaic module and slowing down the failure rate of photovoltaic cells. After the EVA film is produced into a finished product, it needs to be rolled up and stored. During the rolling process, special attention should be paid to dust and impurities in the production environment that may contaminate the film. The existing photovoltaic film dust removal mechanism has the disadvantage of not having an automatic cleaning function when in use, which is not conducive to long-term uninterrupted operation. In addition, when the new photovoltaic film is placed on the mechanism for installation, it is not easy to disassemble, which makes it inconvenient to operate.

[0003] Therefore, it is necessary to propose a dust removal mechanism for photovoltaic film winding to solve the above problems. Utility Model Content

The upper end of the threaded lifting column 4 is fixedly connected to a connecting frame 9 and a connecting beam 10. One side of the connecting frame 9 is movably connected to an upper plate 14.

[0032] In this embodiment, the worm 6, the bevel gear 7 and the bevel gear rod 8 are adapted to drive the threaded volute 2 to rotate, and the rotation of the threaded volute 2 can drive the threaded lifting column 4 to rise and fall, so that the interval between the base frame 1 and the upper plate 14 can be adjusted according to the usage, which is more convenient to operate during use. Example 2

[0033] See also Figure 3 and 6 This embodiment is further optimized on the basis of the embodiment 1. Specifically, an active cavity is opened on the inner side of the connecting beam 10, a first spring 11 is fixedly connected to the inner side of the active cavity, and a bayonet 12 is fixedly connected to the other end of the first spring 11.

[0034] Specifically, one end of the latch 12 is fixedly connected to a pull rod 13 , and the other end of the pull rod 13 passes through the connecting beam 10 .

[0035] Specifically, a card slot 15 is formed on one side of the upper plate 14 , and the card slot 15 is matched with the card pin 12 .

[0036] In this embodiment, by pulling the pull rod 13, the pin 12 can be moved after overcoming the elastic force of the first spring 11, thereby disconnecting the connection with the slot 15, so that the upper plate 14 can be opened when needed, making it easier to install the photovoltaic film to be dusted. Example 3

[0037] See also Figure 4 and 7This embodiment is optimized as follows on the basis of Example 1 or Example 2. Specifically, the upper plate 14 and the inner side of the base frame 1 are rotatably connected with an electrostatic tube 16, and the multiple electrostatic tubes 16 are symmetrically distributed up and down, so that the upper and lower pressures can be symmetrical when the photovoltaic film is squeezed, thereby avoiding the photovoltaic film from being broken due to asymmetric upper and lower pressures. The inner sides of the multiple electrostatic tubes 16 are fixedly installed with cylindrical motors 17, which can provide power for the rotation of the electrostatic tubes 16, and the two ends of the output shafts of the multiple cylindrical motors 17 are respectively fixedly connected to the base frame 1 and the upper plate 14.

[0038] Specifically, the inner sides of the bottom frame 1 and the upper plate 14 are fixedly connected with the second springs 20 , and one end of each of the second springs 20 is fixedly connected with the electrostatic generator 21 , which is matched with the electrostatic tube 16 .

[0039] Specifically, a suction groove 18 is provided on the inner side of the bottom frame 1 and the upper plate 14 , one end of the suction groove 18 is in contact with the electrostatic tube 16 , and an exhaust pipe 19 is provided on the other end of the suction groove 18 .

[0040] In this embodiment, the electrostatic tube 16 can be driven to rotate by the cylindrical motor 17, and the surface of the electrostatic tube 16 can be filled with static electricity by the electrostatic generator 21, so that the dust on the surface of the photovoltaic film can be adsorbed by the static electricity on the surface of the electrostatic tube 16, and the dust adsorbed on the surface of the electrostatic tube 16 can be cleaned by an external vacuum pump through the vacuum pipe 19 and the suction groove 18, so that it can operate for a long time.

[0041] In summary, when the utility model is used, the pull rod 13 is first pulled outward, and after overcoming the elastic force of the first spring 11, the latch 12 is made to slide in the movable cavity on the inner side of the connecting beam 10, so that it is disconnected from the latch slot 15, so that the upper plate 14 is not restricted, so that the upper plate 14 can be opened as needed, and then the photovoltaic film that needs to remove dust can be clamped between the upper plate 14 and the multiple electrostatic tubes 16 on the inner side of the bottom frame 1, and the upper plate 14 is reset, so that the latch 12 is adapted to the latch slot 15 again, so that the upper plate 14 can be limited to avoid displacement during use, and the helical gear rod 8 can be adapted to the two helical gears 7 at the same time by manually rotating the helical gear rod 8, so that the two worm gears 6 can be driven to rotate, so that the multiple threaded worm tubes 2 can be driven to rotate at the same time, The limit column 3 is adapted to the limit hole 5, and the cross-sections of the limit hole 5 and the limit column 3 are both non-circular. At the same time, the threaded volute 2 is adapted to the threaded lifting column 4, so that the lifting and lowering of the threaded lifting column 4 can be realized, so that the interval between the base frame 1 and the upper plate 14 can be adjusted according to the usage, which is more convenient to operate during use. After the interval is adjusted, the electrostatic tube 16 can be driven to rotate by the cylindrical motor 17, and the surface of the electrostatic tube 16 can be filled with static electricity through the electrostatic generator 21, so that the dust on the surface of the photovoltaic film can be adsorbed by the static electricity on the surface of the electrostatic tube 16, and the dust adsorbed on the surface of the electrostatic tube 16 can be cleaned by an external vacuum pump through the exhaust pipe 19 in combination with the suction groove 18, so that it can be able to operate for a long time, thereby achieving the purpose of dust removal.
