Abstract
Description
Technical Field
[0001] The utility model relates to the field of transport packaging, in particular to an impact-resistant barrier assembly. Background Art
[0002] Common vacuum packaging uses barrier materials such as aluminum-plastic film and multi-layer barrier materials such as PA / EVOH / PE composite film. During on-site vacuum packaging, the product is typically wrapped with barrier film, then vacuumed to create a certain degree of vacuum within the cavity formed by the entire package. Finally, the seal is heat-sealed. This packaging method extracts air from the package, reducing moisture inside the cavity and preventing air from entering through the film. While effective, it is a viable and economical method for packaging products with less stringent moisture-proofing requirements. However, for products with very stringent moisture-proofing requirements, this moisture-proofing method cannot meet the product protection needs, as shown in the following points:
[0003] 1. The product is wrapped with packaging film. However, if such a product is placed directly into the packaging box without being connected and fixed to the packaging base or other materials used for transportation, the moisture-proof effect will be affected by the film friction and damage caused by repeated movement of the product in the transportation packaging box.
[0004] 2. When the product needs to be reliably connected to the chassis, metal materials such as screws or rods are often used to penetrate the film to fasten the product to the packaging chassis. Even if glue is applied around the holes formed by the screw penetration or soft cushioning materials are applied, it is difficult to ensure that outside air will not enter the internal cavity during long-term transportation.
[0005] 3. In addition to being fixed to the chassis, the product also needs to be fixed horizontally and vertically. During transportation, the product will inevitably rub against the fixed parts, which may cause the barrier material to be damaged and the vacuum packaging to fail.
[0006] For rolled materials, there is a full-length support shaft in the middle, which is often made of metal round tubes or hard plastic nylon materials. The rolled product wound on the support shaft must not be subjected to other external forces during transportation, and the rolled material must not be directly supported. The support shaft supports the entire rolled material, and when such products are vacuum-packed, the barrier material wraps the support shaft, and then the entire product is placed on the support frame after wrapping. This type of packaging is very likely to be impacted by vehicle brakes during transportation, resulting in friction between the barrier material and the support frame, causing the barrier material to be worn or punctured, and other problems that destroy the vacuum environment.
[0007] In order to solve the above problems, we propose an impact-resistant barrier assembly. Utility Model Content
[0008] The utility model aims to provide an impact-resistant barrier assembly, which has the advantage of being able to withstand impact.
[0009] The above technical objectives of the present invention are achieved through the following technical solutions: an impact-resistant barrier assembly comprising a barrier material, a transparent barrier material embedded within the barrier material, an exhaust valve installed within the transparent barrier material, two hot-pressed components disposed within the barrier material, both the hot-pressed components and the end caps being made of HDPE material, which is a plastic material having good impact resistance and the ability to withstand high pressure without breaking or cracking, and is formed by injection molding or other methods; an end cap is disposed on one side of the hot-pressed component, and a support shaft is sleeved within the end cap;
[0010] The barrier material adopts a multi-layer barrier material such as one of the PA / EVOH / PE composite films, and the exhaust valve adopts a multi-layer barrier material such as one of the PA / EVOH / PE composite films, but needs to be processed into a transparent state.
[0011] By adopting the above technical solution, a seal is formed by arranging end covers and hot pressing components, a seal is formed by arranging barrier materials and hot pressing components for hot pressing, and then the air inside the barrier material is evacuated to form a vacuum by connecting the vacuum device through the exhaust valve, thereby ensuring that external moisture and air do not contact the coiled material. Moreover, after the two end covers are connected to the support shaft, the support shaft and the coiled material on its surface are supported. When the barrier material generates an impact during transportation, the end covers can fully withstand it, and the packaging barrier material will not have any contact with the support frame or the pallet, thereby avoiding the problem of wear and puncture of the barrier material caused by the impact. By using transparent barrier materials, it is convenient for personnel to check whether the internal coiled material is intact after transportation.
[0012] The utility model is further configured as follows: a coil is wound around the surface of the support shaft.
[0013] The utility model is further configured as follows: the end cover and the hot pressing component are processed in one piece.
[0014] By adopting the above technical solution, after the barrier material and the hot pressing component are hot pressed and sealed, the end cover and the hot pressing component are integrally processed into a sealed state, and no air leakage occurs.
[0015] The utility model is further configured as follows: the barrier material is wound around the surfaces of the two hot-pressing components, and the barrier material is also hot-pressed together with the two hot-pressing components.
[0016] By adopting the above technical solution, a sealed space can be formed between the barrier material and the two hot pressing components by hot pressing them together. In addition, the two joint points of the barrier material also need to be hot pressed to form a closed-loop seal, and the two hot pressing components can support the barrier material.
[0017] The utility model is further configured as follows: the air extraction valve is a one-way exhaust valve.
[0018] By adopting the above technical solution, after the barrier material and the two hot-pressing components are hot-pressed together, the exhaust direction of the exhaust valve is from the coil to the outside (from the inside to the outside). The exhaust valve can be connected to a vacuum pump to extract the vacuum. The design of the one-way exhaust valve can prevent outside air from entering the interior of the hot-pressed barrier material and contacting the coil.
[0019] The utility model is further configured as follows: the lower surface of the end cover contacts a support frame, and the bottom of the barrier material is provided with a supporting plate fixedly connected to the support frame.
[0020] The above technical solution is adopted to support the two end covers by providing a support frame and a support plate. During the support process, the barrier material will not have any contact with the support frame or the support plate.
[0021] In summary, the present invention has the following beneficial effects:
[0022] The utility model forms a seal by providing end caps and hot-pressing components, and forms a seal by providing barrier materials and hot-pressing components, and then connects a vacuum device via an exhaust valve to evacuate the air inside the barrier materials to form a vacuum, thereby ensuring that external moisture and air do not contact the coils. Furthermore, after the two end caps are connected to the support shaft, the support shaft and the coils on its surface are supported. When the barrier materials are impacted during transportation, the end caps can fully withstand the impact, and the packaging barrier materials will not have any contact with the support frame or pallet, thereby avoiding the problem of wear and puncture of the barrier materials caused by impact. By using transparent barrier materials, it is convenient for personnel to check whether the internal coils are intact after transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.
[0029] Example 1:
[0030] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a barrier assembly that can withstand impact, including a barrier material 1, a transparent barrier material 7 embedded in the interior of the barrier material 1, an exhaust valve 8 installed inside the transparent barrier material 7, two hot-pressing components 2 are provided inside the barrier material 1, the hot-pressing components 2 and the end caps 3 are both made of HDPE material, which is formed by injection molding or other methods; a plastic material with good impact resistance and the ability to withstand large pressure without breaking or cracking; an end cap 3 is provided on one side of the hot-pressing component 2, and a support shaft 4 is sleeved inside the end cap 3; the barrier material 1 is made of a multi-layer barrier material such as one of the PA / EVOH / PE composite films, and the exhaust valve 8 is made of a multi-layer barrier material such as one of the PA / EVOH / PE composite films, but needs to be processed into a transparent state; a seal is formed by arranging the end caps 3 and the hot-pressing component 2, and a seal is formed by arranging the barrier material 1 and the hot-pressing component 2 for hot pressing, and then the air inside the barrier material 1 is evacuated to form a vacuum by connecting a vacuum device through the exhaust valve 8, so as to ensure that external moisture and air do not contact the roll material. Furthermore, by connecting the two end caps 3 to the support shaft 4, the support shaft 4 and the coiled material on its surface are supported. The end caps 3 can fully withstand any impacts incurred by the barrier material 1 during transportation, and the packaging barrier material 1 will not come into any contact with the support frame 5 or the pallet 6, thereby avoiding the wear and puncture of the barrier material caused by impacts. The use of a transparent barrier material 7 facilitates inspection of the internal coiled material to ensure its integrity after transportation.
[0031] Furthermore, a coil is wound around the surface of the support shaft 4 .
[0032] Furthermore, the end cap 3 and the hot pressing component 2 are processed as one piece. After the barrier material 1 and the hot pressing component 2 are hot pressed and sealed, the end cap 3 and the hot pressing component 2 are processed as one piece into a sealed state, and no air leakage occurs.
[0033] Furthermore, the barrier material 1 is wrapped around the surfaces of the two hot-pressing components 2, and the barrier material 1 is also hot-pressed together with the two hot-pressing components 2. By hot-pressing the barrier material 1 and the two hot-pressing components 2, a sealed space can be formed between the barrier material 1 and the hot-pressing components 2, and the two joint points of the barrier material 1 also need to be hot-pressed to form a closed-loop seal, and the two hot-pressing components 2 can support the barrier material 1.
[0034] Furthermore, the exhaust valve 8 is a one-way exhaust valve. After the barrier material 1 and the two hot-pressing components 2 are hot-pressed, the exhaust direction of the exhaust valve 8 is from the coil to the outside (from the inside to the outside). The exhaust valve 8 can be connected to a vacuum pump to extract the vacuum. The design of the one-way exhaust valve can prevent outside air from entering the interior of the barrier material 1 after hot pressing and contacting the coil.
[0035] Furthermore, the lower surface of the end cover 3 contacts the support frame 5, and the bottom of the barrier material 1 is provided with a support plate 6 fixedly connected to the support frame 5. The support frame 5 and the support plate 6 are arranged to support the two end covers 3. During the support process, the barrier material 1 will not have any contact with the support frame 5 or the support plate 6.
[0036] The process is briefly described as follows: First, a hot-pressing component 2 and an end cap 3 are placed on one end of a support shaft 4. Another hot-pressing component 2 and end cap 3 are then placed on the other end of the support shaft 4. The end cap 3 is then placed on a support frame 5. A whole sheet of barrier material 1 is wrapped around two hot-pressing components 2 and heat-pressed together. The two barrier materials 1 are then heat-pressed together at their joints. A vacuuming device is connected to an air extraction valve 8, and the device is activated to perform vacuuming. As air is extracted during the vacuuming process, the transparent barrier material 7 adheres to the surface of the coil. Once vacuuming is complete, the vacuum packaging is complete.
[0037] During transportation, the impact caused by the vehicle braking will directly act on the end cover 3 and the support frame 5, and the material of the end cover 3 and the support shaft 4 inside the end cover 3 can directly withstand the impact force. In addition, the two end covers 3 and the two support frames 5 can also support the transparent barrier material 7 and the coiled material inside it to be suspended in the air. When the impact force is generated, the transparent barrier material 7 will not have any contact with the support frame 5 or the support plate 6, which can avoid wear and puncture.
[0038] Two threaded holes can be set on the support frame 5. By separating the two semicircular hoops with the same surface size as the end cover 3, placing them on the upper surfaces of the two end covers 3 respectively, and then connecting them through screws and threaded holes, the end covers 3 can be limited to prevent the end covers 3 and the support frame 5 from separating.
[0039] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
