Technical Field

[0001] This utility model relates to the field of photovoltaic film packaging equipment, and in particular to a packaging structure for a photovoltaic film plastic pallet box. Background Technology

[0002] With the increasing global demand for clean energy, the production and sales of photovoltaic modules have been increasing year by year, driving the development of the photovoltaic encapsulant film industry. Photovoltaic encapsulant film plays a key role in the encapsulation process of photovoltaic modules. Its main function is to bond photovoltaic cells, photovoltaic glass and backsheets, protect the cells and encapsulate them into photovoltaic modules that can output direct current. The main types of photovoltaic encapsulant film include transparent EVA film, white EVA film, POE film, EPE film, etc., which are suitable for a variety of application scenarios. The production and transportation of photovoltaic encapsulant film are usually carried out in roll form, and the boxing method is mainly hoisting by crane. Its packaging and storage requirements include rain protection, light protection, high temperature protection, and structural stability. During transportation, the roll material should not be squeezed, and direct sunlight and dust pollution should be avoided. At present, the packaging of encapsulant film is mostly disposable. The form is that a carton is placed on a wooden pallet, the encapsulant film wrapped on the paper core is placed on a wooden support board, and then the box is sealed and packed.

[0003] However, this packaging method has many drawbacks. First, cardboard boxes are easily damaged, and U-shaped openings are usually made for easy handling, allowing dust and impurities to easily enter and affecting the cleanliness of the film. Second, when packaged products are stacked in multiple layers, there is a lack of interlocking structure between the upper and lower layers, making them prone to shaking and tilting during transportation, increasing the risk of damage to the roll material. In addition, cardboard box packaging is cumbersome, time-consuming, and labor-intensive, and materials such as wooden pallets and cardboard boxes are disposable and cannot be recycled.

[0004] Therefore, in view of the problems of the existing film packaging method, such as the easy damage of cardboard boxes, the easy entry of dust through U-shaped openings, the lack of embedding structure during stacking leading to shaking and tilting, cumbersome operation and non-recyclable materials, a packaging structure of photovoltaic film plastic collapsible box can be designed to solve the above problems. Utility Model Content

[0005] In order to overcome the problems that existing packaging methods have in the process of using film packaging, such as easy damage to cardboard boxes, easy dust to enter through U-shaped openings, lack of embedding structure during stacking leading to shaking and tilting, as well as cumbersome operation and non-recyclable materials.

[0006] The technical solution of this utility model is as follows: a packaging structure for a photovoltaic film plastic enclosure box, including a plastic base tray and a plastic box enclosure. The bottom end of the plastic base tray has four stacking recesses, and the front and rear ends of the upper surface of the plastic base tray have lower limiting grooves. The upper end of the plastic base tray is provided with a plastic top cover, and the upper surface of the plastic top cover has four stacking protrusions. The front and rear ends of the lower surface of the plastic top cover have upper limiting grooves, and the lower end of the plastic top cover is provided with a plastic box enclosure. The front and rear ends and four corners of the plastic box enclosure are provided with creases.

Finally, the lower end of the plastic box panel is inserted into the lower ring slot, and the upper ring slot is aligned with the upper end of the plastic box panel, so that the photovoltaic film is wrapped by the box body composed of the plastic base, plastic box panel and plastic top cover. At the same time, the lower limit groove and the upper limit groove limit the upper and lower ends of the metal support frame to suppress the shaking of the metal support frame. When the boxes are stacked, the stacking concave points and stacking convex points are aligned with each other to suppress the shaking and tilting of the boxes. In addition, the plastic box panel can be folded through the creases for easy folding and storage, and multiple plastic bases can also be stacked for easy storage.

[0008] Preferably, a lower ring slot is provided around the lower limit groove, and an upper ring slot is provided around the upper limit groove. The lower end of the plastic box panel is inserted into the lower ring slot, and the upper end of the plastic box panel is inserted into the upper ring slot.

[0009] Preferably, the lower end face of the plastic base has two square annular grooves, and the upper end face of the plastic top cover has grooves for the upper packing strap on both sides.

[0010] Preferably, packing straps are fixed to both sides of the metal support frame, and damping pads are fixed to the bottom of the U-shaped groove.

[0011] Preferably, a limiting baffle is fixed to the outer side of the bottom end of the U-shaped groove, and a tooling support frame is provided on one side of the plastic base.

[0012] Preferably, two right-angle limiting plates are fixedly connected to the tooling support frame. The upper ends of the two right-angle limiting plates are provided with four limiting claws that are fixedly connected to the tooling support frame. The right-angle limiting plates are slidably connected to the lower ring slot, and the limiting claws are slidably connected to the metal support frame.

[0013] Preferably, the upper end of the damping pad is provided with a film-wound core, and the inside of the film-wound core and the upper end of the packing strap limiting piece are both wrapped with inner packing straps.

[0014] The beneficial effects of this utility model are:

[0015] By using a plastic base, plastic top cover, plastic box enclosure, and metal support frame, the photovoltaic film can be wrapped around a film-wrapping core. The core is then placed in a U-shaped groove, and the metal support frame supports both the photovoltaic film and the core. Finally, the lower end of the plastic box enclosure is inserted into the lower ring slot, and the upper ring slot is aligned with the upper end of the enclosure. This creates a box-like structure that completely encloses the photovoltaic film. Simultaneously, the lower and upper limit grooves limit the movement of the metal support frame, preventing it from swaying. Furthermore, when the boxes are stacked, the stacking indentations and stacking protrusions align to suppress shaking and tilting. In addition, the plastic box panels can be folded through creases for easy storage, and multiple plastic base trays can also be stacked for convenient storage. The U-shaped groove is set inside the box to completely block external dust and debris, and the inlay structure suppresses shaking and tilting. The box is constructed with sturdy and recyclable materials to form modular, stackable, and foldable components, increasing recyclability while ensuring ease of use. Attached Figure Description

After being wrapped around the film-coating core 22, the film-coating core 22 is placed in the U-shaped groove 15. The metal support frame 13 supports the photovoltaic film and the film-coating core 22. Finally, the lower end of the plastic box panel 11 is inserted into the lower ring slot 4, and the upper ring slot 9 is aligned with the upper end of the plastic box panel 11. The plastic bottom support 1, the plastic box panel 11, and the plastic top cover 6 form a box to wrap the photovoltaic film. At the same time, the lower limit groove 5 and the upper limit groove 10 limit the upper and lower ends of the metal support frame 13 to suppress the shaking of the metal support frame 13. When the boxes are stacked, the stacking indentation 3 and the stacking protrusion 7 are aligned to suppress the shaking and tilting of the boxes. In addition, the plastic box panel 11 can be folded through the crease 12 for easy folding and storage. Multiple plastic bottom supports 1 can also be stacked for easy storage.

[0025] Please see Figures 1-4In this embodiment, a lower ring slot 4 is provided around the lower limiting groove 5, and an upper ring slot 9 is provided around the upper limiting groove 10. The lower end of the plastic box enclosure 11 is inserted into the lower ring slot 4, and the upper end of the plastic box enclosure 11 is inserted into the upper ring slot 9. Two square annular square tube grooves 2 are provided on the lower end face of the plastic base 1. Upper packing strap grooves 8 are provided on both sides of the upper end face of the plastic top cover 6. After the plastic base 1, plastic box enclosure 11, and plastic top cover 6 form the box body, the upper packing strap grooves 8 can be wrapped around the box. The packing strips are used for fixing, and the upper packing strip groove 8 can be used to limit the sliding of the packing strips outside the box. Packing strip limiting pieces 16 are fixed to both sides of the metal support frame 13. The bottom of the U-shaped groove 15 is fixed with a damping and vibration damping pad 17. The packing strip limiting piece 16 is used to prevent the fixed inner packing strip 23 from sliding downwards. The damping and vibration damping pad 17 is used to reduce the vibration of the wrapping core 22 during the transportation of goods. When the two boxes are stacked one on top of the other, a rigid square tube can be placed at the lower end of the two square tube grooves 2 to enhance the load-bearing capacity.

[0026] Please see Figures 4-5 In this embodiment, a limiting baffle 18 is fixedly connected to the outer side of the bottom end of the U-shaped groove 15. A tooling support frame 19 is provided on one side of the plastic base 1. Two right-angle limiting plates 20 are fixedly connected to the tooling support frame 19. Four limiting claws 21 fixedly connected to the tooling support frame 19 are provided at the upper end of the two right-angle limiting plates 20. The right-angle limiting plates 20 are slidably connected to the lower ring slot 4. The limiting claws 21 are slidably connected to the metal support frame 13. A film-wrapped core 22 is provided at the upper end of the damping and vibration damping pad 17. The inside of the film-wrapped core 22 and the upper end of the packing strap limiting plate 16 are both wrapped with inner packing. When placing the film-wrapping core 22 into the U-shaped groove 15, the tooling support frame 19 and the limiting claw 21 must first limit the U-shaped groove 15 to prevent the metal support frame 13 from tipping over. At the same time, the right-angle limiting piece 20 will be inserted into the lower ring slot 4 to fix the distance between the plastic base 1 and the tooling support frame 19. After the photovoltaic film and the film-wrapping core 22 are placed, the photovoltaic film and the film-wrapping core 22 must first be tied together with the metal support frame 13 using the inner packing strap 23. Then the tooling support frame 19 is removed, and then the plastic box side panel 11 and the plastic top cover 6 are placed.

[0027] When in use, first connect the limiting bottom block 14 with the lower limiting groove 5, and limit the U-shaped groove 15 through the tooling support frame 19 and the limiting claw 21 to prevent the metal support frame 13 from tipping over. At the same time, the right angle limiting piece 20 will be inserted into the lower ring slot 4 to fix the distance between the plastic base 1 and the tooling support frame 19.

[0028] Subsequently, after the photovoltaic film is wrapped around the wrapping core 22, the wrapping core 22 is placed in the U-shaped groove 15 so that the photovoltaic film and the wrapping core 22 are supported by the metal support frame 13. The damping and vibration reduction pad 17 is used to reduce the vibration of the wrapping core 22 during the transportation of goods. After the photovoltaic film and the wrapping core 22 are placed, the photovoltaic film and the wrapping core 22 need to be tied together with the metal support frame 13 by the inner packing strap 23. The packing strap limit piece 16 is used to prevent the fixed inner packing strap 23 from sliding downward. Then the tooling support frame 19 is removed.

[0029] Next, insert the lower end of the plastic box panel 11 into the lower ring slot 4, and then align the upper ring slot 9 with the upper end of the plastic box panel 11, so that the photovoltaic film is wrapped by the box body composed of the plastic base 1, the plastic box panel 11 and the plastic top cover 6. After the box body is composed of the plastic base 1, the plastic box panel 11 and the plastic top cover 6, the packing strip can be wrapped around the position of the upper packing strip groove 8 for fixation, and the upper packing strip groove 8 can be used to limit the sliding of the packing strip outside the box.

[0030] Meanwhile, the lower limit groove 5 and the upper limit groove 10 limit the upper and lower ends of the metal support frame 13 to suppress the shaking of the metal support frame 13. When the boxes are stacked, the stacking indentation 3 and the stacking protrusion 7 are connected to each other to suppress the shaking and tilting of the boxes. In addition, the plastic box side panel 11 can be folded through the crease 12 for easy folding and storage. Multiple plastic base trays 1 can also be stacked one on top of the other for easy storage. When two boxes are stacked one on top of the other, a rigid square tube can be placed at the lower end of the two square tube grooves 2 to enhance the load-bearing capacity.

[0031] Through the above steps, by setting up the plastic base 1, plastic top cover 6, plastic box enclosure 11, and metal support frame 13, the photovoltaic film can be wrapped around the wrapping core 22. The wrapping core 22 is then placed in the U-shaped groove 15, and the metal support frame 13 supports the photovoltaic film and the wrapping core 22. Finally, the lower end of the plastic box enclosure 11 is inserted into the lower ring slot 4, and the upper ring slot 9 is aligned with the upper end of the plastic box enclosure 11. The plastic base 1, plastic box enclosure 11, and plastic top cover 6 form a box that wraps the photovoltaic film. Simultaneously, the lower limit groove 5 and upper limit groove 10 will support the upper and lower ends of the metal support frame 13. The limit is used to suppress the shaking of the metal support frame 13, and the stacking indentation 3 and stacking protrusion 7 are aligned with each other when the boxes are stacked to suppress the shaking and tilting of the boxes. In addition, the plastic box side panel 11 can be folded through the crease 12 for easy folding and storage. Multiple plastic base trays 1 can also be stacked to facilitate storage. The U-shaped groove 15 is set inside the box to completely block external dust and debris. An inlay structure is set to suppress the shaking and tilting of the box. The box is constructed of sturdy and recyclable materials to form modular, stackable, and foldable components, which increases the recyclability of the box while making it convenient to use.
