It should be noted that the concepts such as "first", "second", etc. mentioned in the present utility model are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence relationship of the functions performed by these devices, modules or units.

[0030] It should be noted that the modifications of "one" and "a plurality" mentioned in the present utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless clearly specified otherwise in the context, it should be understood as "one or more".

[0031] The names of the messages or information exchanged between multiple devices in the embodiments of the present utility model are only for illustrative purposes and are not used to limit the scope of these messages or information.

[0032] See Figure 1 and Figure 2, an embodiment of the present utility model provides a roll-changing and material-storing device applied to a photovoltaic film production line, which includes a frame 1. A plurality of material-storing rollers 2 are arranged on the frame 1, and a material-storing interval 3 is arranged between adjacent material-storing rollers 2. Each material-storing roller 2 is respectively driven by a material-storing motor (not shown in the figure). A pressure roller mechanism 4 is arranged at the position of the frame 1 corresponding to the material-storing roller 2. The pressure roller mechanism 4 includes a pressure roller 41, and the pressure roller 41 is in close contact with the material-storing roller 2, so that the photovoltaic film passes through between the pressure roller 41 and the material-storing roller 2. Specifically, the plurality of material-storing rollers 2 can be arranged horizontally or obliquely (not shown in the figure). Among them, the oblique arrangement includes the arrangement modes of broken lines and curves. When the plurality of material-storing rollers 2 are arranged horizontally, the amount of photovoltaic film stored in each material-storing interval 3 can be the same, which is convenient for calculating the storage amount of the photovoltaic film. When the plurality of material-storing rollers 2 are arranged obliquely, the storage amount of the material-storing interval 3 can be increased.

[0033] With the above structure, when storing the photovoltaic film, through the cooperation of the plurality of pressure rollers 41 and the material-storing rollers 2 and being driven by the material-storing motors of each material-storing roller 2, the photovoltaic film can be stored at the material-storing interval 3, and the photovoltaic film naturally hangs down in the material-storing interval 3, so as to prevent the photovoltaic film from being pulled and deformed during storage, ensure the production quality of the photovoltaic film, and make the structure of the roll-changing and material-storing device simple and the manufacturing cost low.

[0034] In one embodiment, see Figure 1 and Figure 2 , the pressure roller mechanism 4 further includes a moving frame 42. The pressure roller 41 is rotatably connected to the moving frame 42, the moving frame 42 is slidably connected to the frame 1, and the moving frame 42 is driven by a moving cylinder 43. In actual use, with the arrangement of the moving frame 42, the moving frame 42 can be driven by the moving cylinder 43 to move on the frame 1, so as to adjust the distance between the pressure roller 41 and the material-storing roller 2 to adapt to photovoltaic films of different thicknesses.

[0035] A moving groove 11 is arranged at the position of the frame 1 corresponding to the moving frame 42, and the moving frame 42 is slidably connected to the moving groove 11. In actual use, with the arrangement of the moving groove 11, the moving frame 42 can move along the moving groove 11 to improve the stability of the movement of the moving frame 42.

[0036] In one embodiment, see Figure 1 and Figure 3 , a feeding end and a discharging end are arranged on the frame 1, and a tensioning mechanism 5 is arranged at the positions of the frame 1 corresponding to the feeding end and the discharging end. The tensioning mechanism 5 includes a tensioning roller 51 that moves relative to the material-storing roller 2. In actual use, with the arrangement of the tensioning roller 51, the tension of the photovoltaic film between the feeding end and the discharging end of the frame 1 and the adjacent material-storing rollers 2 can be ensured, and it can be avoided that when the photovoltaic film enters or exits the material-storing roller 2, the too small tension affects the quality of the photovoltaic film.

[0037] The tensioning mechanism 5 further includes a tensioning frame 52. The tensioning roller 51 is rotatably connected to the tensioning frame 52, and the tensioning frame 52 is driven to move by a tensioning cylinder 53. In actual use, with the arrangement of the tensioning frame 52, when the tensioning frame 52 is driven to move by the tensioning cylinder 53, it is convenient to adjust the tension of the photovoltaic film.

[0038] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0039] Those skilled in the art should understand that the above embodiments are only for clearly explaining the present utility model, rather than limiting the scope of the present utility model.
