Description

Technical Field

[0001] The utility model relates to the technical field of portable box group power supplies, in particular to a fiber reinforced film cutting device for a portable box group power supply. Background Art

[0002] Photovoltaic power generation, as a renewable energy generation technology, has been widely used around the world. Traditional photovoltaic power stations are mostly in the form of fixed ground power stations or distributed power stations combined with buildings. The electricity generated by these power stations is mainly used locally or transmitted to other areas through long-distance power lines, thus forming a beneficial supplement to the traditional power grid. However, in certain specific situations, such as remote areas with relatively scarce power supply, outdoor work scenes, and power outages caused by disasters, traditional photovoltaic power stations or power grids are difficult to meet immediate and flexible power needs.

[0003] At present, portable box power supplies are used to solve the above problems. The portable box power supplies adjust the number, size, and storage method of foldable flexible photovoltaic panels. After the flexible photovoltaic panels are unfolded, they can be connected to the energy storage box through cables to charge the energy storage box. Among them, the front and back of the flexible photovoltaic panels use fiber-reinforced film as packaging materials, and the middle is the core solar cell power generation component. The battery is first cut into small pieces by laser, and a specific number of small pieces are then connected in series by equipment to form the structure required by our specific product. The equipment is heated and pressurized to shape the structure, and multiple photovoltaic panels are sewn together through waterproof cloth. The photovoltaic panels are connected in series and parallel with cables inside the waterproof cloth. However, there is a fiber structure inside the fiber-reinforced film, which cannot be cut by traditional film cutters. The current method of cutting fiber-reinforced film is manual cutting, which is time-consuming and labor-intensive. Moreover, when a roll of fiber-reinforced film is used up, it needs to be replaced and repositioned before cutting can be performed again. The operation is cumbersome and reduces work efficiency. Therefore, the above problems need to be solved urgently. Summary of the invention
