Description

Technical Field

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

[0002] Photovoltaic power generation, as a renewable energy technology, has been widely adopted worldwide. Traditional photovoltaic power stations mostly exist in the form of fixed ground-mounted power stations or distributed power stations integrated with buildings. The electricity generated by these stations is primarily used locally or transmitted to other areas via long-distance power lines, thus supplementing traditional grid power supply. However, in certain specific situations, such as remote areas with relatively scarce power supply, outdoor work scenarios, and areas without power due to disasters, traditional photovoltaic power stations or grid power supply methods cannot meet the immediate and flexible power demand.

[0003] Currently, portable box-type power supplies are used to solve the above problems. The portable box-type power supplies adjust the number, size, and storage method of foldable flexible photovoltaic panels. After unfolding, the flexible photovoltaic panels can be connected to the energy storage box via cables to charge the energy storage box. Among them, the front and back of the flexible photovoltaic panels use fiber-reinforced film as the packaging material, 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 for our specific product. The equipment is heated and pressurized to shape it, and multiple photovoltaic panels are then sewn together through waterproof cloth. The photovoltaic panels are connected in series and parallel with cables inside the waterproof cloth. However, the fiber-reinforced film has a fiber structure inside, 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 carried out again. The operation is cumbersome and reduces work efficiency. Therefore, the above problems need to be solved urgently. Summary of the Invention

[0036] The working principle of this utility model:

[0037] First, the cutting assembly 31 is retracted to the rearmost side, and the fiber-reinforced membrane on the right unwinding roller 12 is unwound between the upper guide roller 14 and the lower guide roller 15 onto the workbench 16. During this process, the electric push rod 21, the pressure claw 22 and the pressure roller 23 are used in coordination to ensure that the fiber-reinforced membrane can be unwound in an orderly manner. After confirming the required cutting length, the abutment wheel 19 is driven by the cylinder 18 to contact the fiber-reinforced membrane, thereby ensuring the stability of the cutting operation. Then, with human assistance, the cutting assembly 31 moves forward horizontally and longitudinally along with the U-shaped frame 26, and through its own high-speed rotation, the fiber-reinforced membrane cutting operation is carried out.

[0038] When the unwinding roller 12 needs to be replaced, under the drive of the first motor 7, through the meshing cooperation of the main bevel gear 5 and the slave bevel gear 6, the rotating plate 9 is horizontally rotated 180°, and then the next unwinding roller 12 is horizontally rotated to the right side to continue the unwinding operation. At this time, the unwinding roller 12 on the left side can be replaced.
