Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging, in particular to a foldable packaging for a PET film roll. Background Art
[0002] After the PET film is wound up, the PET film roll needs to be placed on a tray for easy storage, accommodation and positioning. Later, it is also convenient to move the tray with a forklift. Under the existing technology, the tray usually adopts a wooden structure, and wooden boards also need to be arranged on both sides of the film roll to support the film roll. Although the cost is low, the load-bearing capacity of the wooden structure is limited, and it cannot be fireproof, waterproof and moisture-proof.
[0003] Moreover, when the output of the film roll is large, the corresponding trays also need to be increased. Such wooden trays cannot be stacked in multiple layers during storage, and they will also occupy a large space when not loaded with film rolls. Therefore, the space utilization rate is low. Summary of the Utility Model
[0004] To solve the problem that the wooden trays under the existing technology cannot be stacked in multiple layers during storage and will also occupy a large space when not loaded with film rolls, so the space utilization rate is low, this application provides a foldable packaging for a PET film roll, and the specific scheme is as follows.
[0005] A foldable packaging for a PET film roll includes a bottom plate and side plates. The side plates include long-side side plates and wide-side side plates. The long-side side plates are hinged on both sides of the bottom plate in the length direction, and the wide-side side plates are hinged at both ends of the bottom plate in the length direction. When the side plates are rotated to the limit position, they can all abut against the bottom plate, and the side plates are stacked when retracted.
[0006] By adopting the above technical solution, the side plates are directly hinged to the bottom plate, and the side plates can be retracted for storage when not in use. When the side plates are stored, the side plates can be stacked to form a relatively thick plate body, so as to improve the space utilization rate during storage. At the same time, when the side plates are rotated to the limit position, they can abut against each other to form a fixed box body, and the side plates can also abut against the loaded film roll to stabilize the shape.
[0007] Optionally, an embedding groove is provided on the bottom plate corresponding to the wide-side side plates, and the wide-side side plates can be embedded in the embedding groove when retracted.
[0008] By adopting the above technical solution, an embedding groove is provided on the bottom plate corresponding to the wide-side side plates. Since the wide-side side plates are arranged at both ends, it is difficult to contact when the length of the wide-side side plates is not set too long. Therefore, as long as the two wide-side side plates are embedded in the embedding groove, the wide-side side plates can be stacked under the long-side side plates to achieve storage.
[0009] Optionally, ribs are provided on both sides of the embedding groove in the length direction, and the long-side side plate is hinged to the ribs.
[0010] By adopting the above technical solution, ribs are provided on both sides of the embedding groove in the length direction, and the long-side side plate is hinged to the ribs, so that it can be directly located above the embedding groove. Therefore, it can also be on the upper side of the wide-side side plate after being folded, thus realizing stacked storage, further improving the stacking effect and space utilization rate.
[0011] Optionally, the rib on one side of the embedding groove is thicker than the rib on the other side.
[0012] By adopting the above technical solution, the rib on one side is thicker than the rib on the other side, and the long-side side plate on one side can be directly on the upper side of the long-side side plate on the other side after being folded, thus completing the stacked storage.
[0013] Optionally, a groove is provided on the long-side side plate, and the groove is arranged corresponding to the shape of the film roll reel.
[0014] By adopting the above technical solution, a groove corresponding to the shape of the film roll is provided on the long-side side plate. When the film roll is placed, the groove can position and limit the film roll, thereby reducing the situation of the film roll moving in the package and improving the storage stability.
[0015] Optionally, guiding inclined surfaces are provided on both sides of the groove, and the side of the guiding inclined surface away from the groove is higher than the side close to the groove.
[0016] By adopting the above technical solution, guiding inclined surfaces are provided on both sides of the groove. When the film roll is placed, it can roll along the guiding inclined surface and thus fall into the groove. When the reel is not aligned with the groove, it can also be guided and aligned into the groove, further improving the convenience.
[0017] Optionally, two groups of grooves and guiding inclined surfaces are provided on the long-side side plate.
[0018] By adopting the above technical solution, two groups of grooves and guiding inclined surfaces are provided, so that two film rolls can be placed in one package, further improving the convenience of placement and handling.
[0019] Optionally, convex blocks are provided at both ends of the long-side side plate in the length direction, clamping grooves are correspondingly provided on the wide-side side plate, and the convex blocks are used for being embedded into the clamping grooves.
[0020] By adopting the above technical solution, convex blocks are provided in the length direction of the long-side side plate, and the convex blocks can be embedded into the clamping grooves to form clamping, thereby improving the stability after forming the box body.
[0021] Optionally, a handling groove is further provided on the bottom plate, and the handling groove is arranged along the length direction of the bottom plate.
[0022] By adopting the above technical solution, a handling groove is provided on the bottom plate, and the handling groove is arranged along the length direction of the bottom plate. When a forklift is used for handling, it can be embedded in the handling groove, and it is less likely to fall off the forklift during the handling by a forklift, thereby improving the convenience and stability during handling.
[0023] Optionally, the bottom plate includes a PET foam board, and the side plates also include PET foam boards.
[0024] By adopting the above technical solution, the PET foam board has high mechanical strength, stiffness and hardness, and has waterproof performance, and is not prone to mildew and other situations similar to those of wooden pallets, is not easily damaged and has better load-bearing performance.
[0025] In summary, the present application has at least the following beneficial effects:
[0026] 1. The present application solves the problem that in the prior art, wooden pallets cannot be stacked in multiple layers during storage, and will also occupy a large space even when the film rolls are not loaded, so the space utilization rate is low. By providing a foldable bottom plate and side plates, the side plates can be folded when storage is not required, and the entire package can be folded into a plate shape for storage, thereby improving the space utilization rate, and the side plates can be propped up when in use.
[0027] 2. The present application also uses PET foam boards as the bottom plate and side plates. The PET foam boards have excellent physical properties, can not only improve the load-bearing strength, but also have waterproof performance, can reduce the humidity during storage, and further improve the storage effect.

[0034] The following further details the present application through specific embodiments in conjunction with the drawings.
[0035] A foldable package for a PET film roll, comprising a bottom plate 1 and side plates. The side plates include long-side side plates 2 and wide-side side plates 3. The long-side side plates 2 are hingedly arranged on both sides of the bottom plate 1 in the length direction, and the wide-side side plates 3 are hingedly arranged at both ends of the bottom plate 1 in the length direction. When the side plates are rotated to the extreme positions, they can all abut against the bottom plate 1. When the side plates are retracted, they are stacked. In specific implementation, when the film roll needs to be stored, the side plates can be erected for storage. When not in use, the side plates are retracted, so as to realize the storage of the package, further improving the space utilization rate. The hinge between the side plates and the bottom plate 1 is realized by means of hinges. During the rotation process, the side plates can abut against the bottom plate 1 at both extreme positions, so as to form positioning. After the film roll is placed, it can further support the side plates. In other embodiments, rotation can also be carried out by arranging hinge rods.
[0036] As Figure 1 and Figure 2 shown, an embedding groove 11 is provided on the bottom plate 1 corresponding to the wide-side side plate 3. When the wide-side side plate 3 is retracted, it can be embedded in the embedding groove 11. In specific implementation, the embedding groove 11 runs through the bottom plate 1 along the length direction. The length of the wide-side side plate 3 is less than half of the length of the embedding groove 11. Therefore, the two wide-side side plates 3 will not interfere with each other during storage. When storing, the two wide-side sides can be respectively stored at both ends of the embedding groove 11.
[0037] As Figure 1 and Figure 2 shown, convex strips 12 are provided on both sides of the embedding groove 11 in the length direction. The long-side side plates 2 are hinged to the convex strips 12. The thickness of the convex strip 12 on one side of the embedding groove 11 is thicker than that of the convex strip 12 on the other side. In specific implementation, the height of the long-side side plate on the side where the convex strip 12 is thicker is less than that of the long-side side plate 2 on the side where the convex strip 12 is thinner. The tops of the two long-side side plates 2 are at the same horizontal height. When folding and storing, the long-side side plate 2 on the side where the convex strip 12 is higher can just be folded onto the upper side of the long-side side plate 2 on the other side, so as to complete the folding and storage. After folding, as Figure 2 shown in, the space utilization rate is increased.
[0038] As Figure 1 and Figure 2As shown, a groove 21 is formed on the long-side side plate 2, and the groove 21 is arranged corresponding to the shape of the film roll reel. Guide inclined surfaces 211 are provided on both sides of the groove 21, and the side of the guide inclined surface 211 away from the groove 21 is higher than the side close to the groove 21. Two sets of the groove 21 and the guide inclined surface 211 are provided on the long-side side plate 2, and the two sets of the groove 21 and the guide inclined surface 211 are arranged along the length direction of the long-side side plate 2. During specific implementation, the reel of the film roll can just be embedded in the groove 21, and the groove 21 can play a role in limiting and positioning the reel, reducing the situation that the film roll moves in the reel, improving the stability of the film roll in the package, and the guide inclined surface 211 can guide the product into the inside of the groove 21 when the reel does not face the groove 21, so as to send the reel of the film roll into the groove 21 to achieve positioning.
[0039] As Figure 1 and Figure 2 shown, bumps 22 are provided at both ends of the long-side side plate 2 in the length direction, and clamping grooves 31 corresponding to the bumps 22 are provided on the wide-side side plate 3, and the bumps 22 are used for being embedded in the clamping grooves 31. During specific implementation, after the long-side side plate 2 and the wide-side side plate 3 are erected, the bumps 22 can be embedded in the clamping grooves 31 to achieve clamping, thereby restricting the rotation of the long-side side plate 2 and the wide-side side plate 3, improving the strength after the package is formed, and reducing the situation that the side plates fall again to affect the packaging stability.
[0040] As Figure 1 and Figure 2 shown, a handling groove 13 is further provided on the bottom plate 1, and the handling groove 13 is arranged along the length direction of the bottom plate 1. During specific implementation, the handling groove is arranged at the bottom of the bottom plate 1, and a forklift or a hydraulic truck can just cooperate with the handling groove 13 during handling, further improving the handling convenience and efficiency of the product.
[0041] As Figure 1 and Figure 2 shown, the bottom plate 1 includes a PET foam board, and the side plates also include PET foam boards. During specific implementation, the PET foam board has strong mechanical strength and high waterproofness, and can further improve the service life.
[0042] Working principle: When not in use, the wide-side side plate 3 can be first folded and stored, and then the long-side side plate 2 can be folded and stored. At this time, the storage can be completed, thereby improving the convenience of packaging storage. When the film roll needs to be stored, the side plates are erected to form a box-type package. During the packaging process, the reel of the film roll can be sent into the groove 21 along the guide inclined surface 211 to complete the storage.
[0043] The above is the preferred embodiment of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
