Description

Technical Field

[0001] This application relates to the field of packaging bag structure technology, and in particular to a cushioning air bag and a cushioning air bag processing technology. Background Technology

[0002] Air cushioning bags are a type of cushioning packaging that is becoming increasingly widely used. Utilizing air as a protective barrier, they maximize resource conservation and reduce waste. Furthermore, their flat, uninflated state significantly reduces logistics and warehousing costs, and after inflation, they can be punctured to release air, making them easy to recycle. Currently, they are widely used in e-commerce, logistics, consumer goods, and industrial products.

[0003] In current technology, when using a cushioning air bag, the air inside needs to be vented before it can be returned to a flat state for recycling. Generally, this is done by puncturing the cushioning air bag. As a result, the cushioning air bag can only be used once, which is not conducive to reuse and causes serious waste of resources.

[0004] Therefore, how to achieve the recyclability and reuse of cushioning air bags is a technical problem that urgently needs to be solved. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] It should be understood that, in the description of this application, unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0041] It should also be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0042] Example 1

[0043] This application provides a cushioning air bag, as shown in the reference. Figure 1 The bag includes: a first film 1, a second film 2, an exhaust assembly 3, and an adhesive assembly 4. The first film 1 and the second film 2 are sealed around their perimeter, leaving only an air inlet to form a bag body. One end of the bag body has an air inlet channel 5 connected to the air inlet. One or more exhaust assemblies 3 are provided on the first film 1 and / or the second film 2, and adhesive assemblies 4 are provided between adjacent exhaust assemblies 3.

[0044] Specifically, the cushioning air bag includes a first film 1, a second film 2, an exhaust assembly 3, and an adhesive assembly 4. The first film 1 can be the upper film, and the second film 2 can be the lower film; similarly, the first film 1 can be the lower film, and the second film 2 can be the upper film; no specific limitation is made here. The following explanation uses the example of the first film 1 as the upper film and the second film 2 as the lower film. The first film 1 and the second film 2 are sealed around their perimeter, leaving only an air inlet to form the bag body, as shown in the reference. Figure 1One end of the bag body is provided with an air inlet channel 5, and the end of the air inlet channel 5 is provided with an air inlet seal. The air inlet channel 5 is connected to the air inlet. Inflation is performed by connecting the inflation nozzle to the opening of the air inlet channel 5, allowing the bag body to be inflated through the air inlet via the air inlet. One or more exhaust components 3 are provided on the first film 1 and / or the second film 2, and an adhesive component 4 is provided between adjacent exhaust components 3. It should be noted that the exhaust components 3 and adhesive components 4 are arranged alternately, that is, an adhesive component 4 is placed every other exhaust component 3. When the cushioning air bag is reused, the cushioning air bag can be vented simply by pulling the last exhaust component 3. After the cushioning air bag is vented, it can be heat-sealed by the adhesive component 4 arranged adjacent to the last exhaust component 3. After bonding, it can be inflated by connecting the inflation nozzle to the opening of the air inlet channel 5, allowing the bag body to be inflated through the air inlet via the air inlet via the air inlet. Then, pulling the last vent assembly 3 will vent the cushioning air bag again. After the cushioning air bag is vented again, it can be heat-sealed again through the adhesive assembly 4 adjacent to the last vent assembly 3. After bonding, it can be inflated again by connecting the inflation nozzle to the opening of the air inlet channel 5, allowing the bag to continue to be inflated through the air inlet. It should be noted that the number of vent assemblies 3 and adhesive assemblies 4 can be arranged according to actual usage needs, and the number of adhesive assemblies 4 indicates the number of times the bag needs to be reused. In particular, the reuse of the cushioning air bag can also be achieved by discarding the damaged parts cut off after recycling and resealing them. By adopting this structural form, after the cushioning air bag is used up, simply pulling the end venting component 3 can cut the cushioning air bag to release the air, allowing the cushioning air bag to return to a flat state for easy recycling. It can also re-heat-seal the recycled cushioning air bag through the built-in adhesive component 4, which can strengthen the seal and indicate the resealing position, enabling the recycling and reuse of the cushioning air bag without relying on additional tools. In addition, the number of times the adhesive component 4 is arranged determines the number of times the cushioning air bag can be reused. The number of times the cushioning air bag can be reused can be selected according to the actual application scenario conditions such as product weight, strength, and logistics conditions, which has strong flexibility and scenario adaptability.

[0045] In some embodiments, when there is one exhaust assembly 3, the adhesive component 4 is disposed on the side of the exhaust assembly 3 near the air inlet. When there are multiple exhaust assemblies 3, an adhesive component 4 is provided between every two adjacent exhaust assemblies 3, and the exhaust assembly 3 closest to the air inlet among all exhaust assemblies 3 is also provided with an adhesive component 4 on the side closest to the air inlet.

[0046] For example, when there is only one exhaust assembly 3, the adhesive assembly 4 is located on the side of the exhaust assembly 3 near the air inlet. When the cushioning air bag needs to be vented after use, it can be vented simply by pulling the last exhaust assembly 3. After the cushioning air bag is vented, it can be heat-sealed by the adhesive assembly 4 arranged adjacent to the last exhaust assembly 3. At this time, the adhesive assembly 4 is located on the side of the exhaust assembly 3 near the air inlet. After bonding, it can be inflated by connecting the inflation nozzle to the opening of the air inlet channel 5, and the bag can continue to be inflated through the air inlet through the air inlet channel 5. This is an example of an implementation scenario when there is only one exhaust assembly 3. In this case, the cushioning air bag can be reused once and can be applied to lightweight scenarios.

[0047] For example, when there are multiple exhaust components 3, an adhesive component 4 is provided between every two adjacent exhaust components 3, and the exhaust component 3 closest to the air inlet is also provided with an adhesive component 4 on the side closest to the air inlet. The exhaust components 3 and adhesive components 4 are arranged alternately, that is, an adhesive component 4 is arranged every other exhaust component 3. When the cushioning air bag is reused, it is only necessary to pull the last exhaust component 3 to exhaust the air bag; after the cushioning air bag is exhausted, it can be heat-sealed by the adhesive component 4 arranged adjacent to the last exhaust component 3. After bonding, it can be inflated by connecting the inflation nozzle to the opening of the air inlet channel 5, and the bag can continue to be inflated through the air inlet through the air inlet channel 5. Then, pulling the last exhaust component 3 will again vent the cushioning air bag. After the cushioning air bag is vented again, it can be heat-sealed again through the adhesive component 4 adjacent to the last exhaust component 3. After bonding, it can be inflated again by connecting the inflation nozzle to the opening of the air inlet channel 5, allowing the bag to continue to be inflated through the air inlet. If there is an adhesive component 4 between every two adjacent exhaust components 3, and the exhaust component 3 closest to the air inlet has an additional adhesive component 4 on the side closest to the air inlet, after the last venting through the exhaust component 3, it can be heat-sealed again through the adhesive component 4 located inside the last exhaust component 3. After bonding, it can be inflated again by connecting the inflation nozzle to the opening of the air inlet channel 5, allowing the bag to continue to be inflated through the air inlet, thus reusing it once more. That is, compared to the embodiment where adhesive components 4 are only set between exhaust components 3, it can be reused once more through the last adhesive component 4. If adhesive components 4 are only installed between the exhaust components 3, the air can be vented and recovered through the last exhaust component 3 after the last adhesive component 4 is heat-sealed and inflated again, facilitating air release and recovery. Both implementation methods have their advantages and can be selected according to actual application needs. By adopting this structural form, the arrangement of the adhesive components 4 determines whether the air bag is reused once more or facilitates final air release and recovery. The number of adhesive components 4 determines the number of times the cushioning air bag can be reused. The number of reuses can be selected based on actual application conditions such as product weight, strength, and logistics conditions, offering greater flexibility and adaptability to different scenarios.

[0048] In some embodiments, the exhaust assembly 3 is provided with a plastic film groove 6 at the position corresponding to the first film 1 and / or the second film 2.

[0049] Specifically, the plastic film groove 6 can be formed by pressing with an improved cooling roller 103 having a groove structure. The design of the plastic film groove 6 facilitates its cooperation with the exhaust assembly 3 to cut the buffer air bag, thereby making it easier to exhaust air, which can achieve the technical effects of saving effort and making operation convenient.

[0050] In some implementations, refer to Figure 2 The exhaust assembly 3 includes an exhaust line 31 and a pull ring 32. The exhaust line 31 is located inside the bag, and the pull ring 32 is located outside the bag and connected to the exhaust line 31.

[0051] Specifically, the venting assembly 3 includes a venting line 31 and a pull ring 32. The venting line 31 is connected to the pull ring 32, allowing the user to easily operate the venting line 31 to cut along the groove 6 of the plastic film for venting. The venting line 31 is located inside the bag and can be laid on the first film 1 and / or the second film 2. In particular, the venting line 31 can be laid on the second film 2 (taking the second film 2 as the lower film as an example), allowing the adhesive assembly 4 and the venting line 31 to be placed directly on the second film 2, further simplifying the manufacturing process. The venting line 31 is embedded in the groove 6 of the plastic film. The venting line 31 can be made of polyamide resin material or polyester plastic rope, as long as the tensile strength meets the requirements for use; this is only an example and not a specific limitation. By adopting the structure of the exhaust line 31 and the pull ring 32, the operator can easily operate the exhaust line 31 to cut and exhaust air along the plastic film groove 6 through the pull ring 32. The operation is convenient and facilitates the exhaust and recovery of the buffer air bag. In addition, the design of the plastic film groove 6 and the exhaust line 31 working together can also ensure the shape of the buffer air bag after exhaust, so as not to affect the next use and improve the user experience.

[0052] In some embodiments, the bag body is provided with one or more heat-sealing lines 7, which divide the bag body into multiple air column cavities 8. Each air column cavity 8 is provided with a one-way valve diaphragm 9 connected to the air inlet.

[0053] Specifically, the bag body is provided with one or more heat-sealing lines 7, which can divide the bag body into multiple air column cavities 8, thereby providing a reliable protective effect for heavy products. A one-way valve diaphragm 9 is located between the air inlet channel 5 and the air column cavities 8. One end of the one-way valve diaphragm 9 is connected to the air inlet, and the other end is connected to each air column cavity 8, so that air can be continued to be injected into each air column cavity 8 through the air inlet channel 5 and then through the air inlet.

[0054] In some embodiments, the first film 1 and the second film 2 include a first polyethylene resin layer and a first polyamide resin layer, with the first polyethylene resin layer disposed on both sides of the first polyamide resin layer. The adhesive component 4 includes a second polyethylene resin layer and a second polyamide resin layer, with the second polyethylene resin layer disposed on both sides of the second polyamide resin layer.

[0055] In some embodiments, the thickness of the second polyethylene resin layer is greater than the thickness of the first polyethylene resin layer.

[0056] Specifically, the first film 1, the second film 2, and the adhesive component 4 all adopt a material structure arrangement of polyethylene resin layer-polyamide resin layer-polyethylene resin layer. The difference lies in that the thickness of the polyethylene resin layer on both sides of the adhesive component 4 is greater than the thickness of the polyethylene resin layers on both sides of the first film 1 and the second film 2. By adopting this structural form, the polyethylene resin layers on both sides have good adhesion, and the inner polyamide resin layer has good toughness; while the second polyamide resin layer of the adhesive component 4 is thicker, resulting in stronger adhesion and facilitating heat sealing.

[0057] In this embodiment, after the cushioning air bag is used up, simply pulling the end venting component 3 can cut the cushioning air bag to release air, allowing it to return to a flat state for easy recycling. Furthermore, the built-in adhesive component 4 can reseal the recycled cushioning air bag, strengthening the seal and indicating the resealing position. This allows for the recycling and reuse of the cushioning air bag without relying on additional tools. Additionally, the number of adhesive components 4 determines the number of times the cushioning air bag can be reused. The number of reuses can be selected based on actual application conditions such as product weight, strength, and logistics, offering high flexibility and adaptability.

[0058] Example 2

[0059] Corresponding to the above embodiments, this application also provides a process for processing a cushioning air bag, including:

[0060] S1. Prepare the first thin film 1 and the second thin film 2;

[0061] S2. Lay the exhaust assembly 3 and the adhesive assembly 4 at designated positions on the first film 1 and / or the second film 2 at intervals, and fix them with heat adhesive;

[0062] S3. Align the first film 1 and the second film 2, and seal the four sides, leaving only the air inlet to form a bag;

[0063] S4. The heat sealing line 7 is completed by the column sealing mold to divide the bag into multiple air column cavities 8.

[0064] Specifically, a first film 1 and a second film 2 are first prepared. For example, the first film 1, the second film 2, and the adhesive component 4 are all arranged with a material structure of polyethylene resin layer-polyamide resin layer-polyethylene resin layer, the difference being that the thickness of the polyethylene resin layer on both sides of the adhesive component 4 is greater than the thickness of the polyethylene resin layer on both sides of the first film 1 and the second film 2.

[0065] Specifically, when there is only one exhaust assembly 3, the adhesive assembly 4 is located on the side of the exhaust assembly 3 near the air inlet. When the cushioning air bag needs to be vented after use, it can be vented simply by pulling the last exhaust assembly 3. After the cushioning air bag is vented, it can be heat-sealed by the adhesive assembly 4 arranged adjacent to the last exhaust assembly 3. At this time, the adhesive assembly 4 is located on the side of the exhaust assembly 3 near the air inlet. After bonding, it can be inflated by connecting the inflation nozzle to the opening of the air inlet channel 5, and the bag can continue to be inflated through the air inlet through the air inlet channel 5. This is an example of an implementation scenario when there is only one exhaust assembly 3. In this case, the cushioning air bag can be reused once and can be applied to lightweight scenarios.

[0066] Specifically, when there are multiple exhaust components 3, an adhesive component 4 is provided between every two adjacent exhaust components 3, and the exhaust component 3 closest to the air inlet also has an adhesive component 4 on the side closest to the air inlet. The exhaust components 3 and adhesive components 4 are arranged alternately, that is, an adhesive component 4 is placed every other exhaust component 3. When the cushioning air bag is reused, it is only necessary to pull the last exhaust component 3 to exhaust the air bag; after the cushioning air bag is exhausted, it can be heat-sealed by the adhesive component 4 arranged next to the last exhaust component 3. After bonding, it can be inflated by connecting the inflation nozzle to the opening of the air inlet channel 5, and the bag can continue to be inflated through the air inlet through the air inlet channel 5. Then, pulling the last exhaust component 3 will again vent the cushioning air bag. After the cushioning air bag is vented again, it can be heat-sealed again through the adhesive component 4 adjacent to the last exhaust component 3. After bonding, it can be inflated again by connecting the inflation nozzle to the opening of the air inlet channel 5, allowing the bag to continue to be inflated through the air inlet. If there is an adhesive component 4 between every two adjacent exhaust components 3, and the exhaust component 3 closest to the air inlet has an additional adhesive component 4 on the side closest to the air inlet, after the last venting through the exhaust component 3, it can be heat-sealed again through the adhesive component 4 located inside the last exhaust component 3. After bonding, it can be inflated again by connecting the inflation nozzle to the opening of the air inlet channel 5, allowing the bag to continue to be inflated through the air inlet, thus reusing it once more. That is, compared to the embodiment where adhesive components 4 are only set between exhaust components 3, it can be reused once more through the last adhesive component 4. If adhesive components 4 are only installed between the exhaust components 3, the air can be vented and recovered through the last exhaust component 3 after the last adhesive component 4 is heat-sealed and inflated again, facilitating air release and recovery. Both implementation methods have their advantages and can be selected according to actual application needs. By adopting this structural form, the arrangement of the adhesive components 4 determines whether the air bag is reused once more or facilitates final air release and recovery. The number of adhesive components 4 determines the number of times the cushioning air bag can be reused. The number of reuses can be selected based on actual application conditions such as product weight, strength, and logistics conditions, offering greater flexibility and adaptability to different scenarios.

[0067] Specifically, depending on the actual application scenario and the required number of reusable uses of the cushioning airbag, the venting assembly 3 and the adhesive assembly 4 can be laid at designated positions on the first film 1 and / or the second film 2 at intervals, and then thermally bonded together. The venting assembly 3 can be laid on the first film 1 and / or the second film 2. In particular, the venting assembly 3 includes a venting line 31 and a pull ring 32. The venting line 31 can be laid on the second film 2 (taking the second film 2 as the lower film as an example). The adhesive assembly 4 and the venting line 31 can be directly placed on the second film 2, further simplifying the manufacturing process.

[0068] In this embodiment, by adopting such a manufacturing process, the cushioning air bag can be customized according to the actual application scenario and the number of times it needs to be reused. The number of times the bonding components 4 are arranged is the number of times the cushioning air bag can be reused. The number of times the cushioning air bag can be reused can be selected according to the actual application scenario conditions such as product weight, strength and logistics conditions, which has strong flexibility and scenario adaptability.

[0069] In some embodiments, the processing technology further includes:

[0070] 101. A first film 1 and / or a second film 2 with plastic film grooves 6 are prepared by a groove extrusion device 10;

[0071] 102. Lay the exhaust assembly 3 inside the film with the plastic film groove 6.

[0072] Specifically, the plastic film groove 6 can be formed by pressing with an improved cooling roller 103 having a groove structure. The design of the plastic film groove 6 facilitates its cooperation with the exhaust assembly 3 to cut the buffer air bag, thereby making it easier to exhaust air and achieving the technical effects of saving effort and making operation convenient. In addition, the design of the plastic film groove 6 and the exhaust line 31 together can also ensure the shape of the buffer air bag after exhaust, so as not to affect the next use and improve the user experience.

[0073] In some implementations, refer to Figure 3 The grooved extrusion device 10 includes an extruder 101, an auxiliary pressing roller 102, an improved cooling roller 103, and a take-up roller 104. The extruder 101 includes an extrusion nozzle 1011, and the improved cooling roller 103 is provided with a grooved assembly 1031. The extrusion clamp aligns with the gap between the auxiliary pressing roller 102 and the improved cooling roller 103. The auxiliary pressing roller 102 and the improved cooling roller 103 calender the material to form a film with plastic film grooves 6, and then wind it up using the take-up roller 104.

[0074] Specifically, the extrusion device 10 also includes a drive assembly and a cooling system. The auxiliary pressing roller 102 and the improved cooling roller 103 rotate relative to each other. The drive assembly drives the improved cooling roller 103 to rotate, thereby rotating the auxiliary pressing roller 102. The cooling system provides cooling for the improved cooling roller 103. For example, the cooling system may include an inlet pipe connected to one end of the improved cooling roller 103 and an outlet pipe connected to the other end of the improved cooling roller 103. The cooling system may also include a cooling water tank for cooling the cooling water. The inlet end of the inlet pipe is connected to one side of the cooling water tank, and the outlet end of the outlet pipe is connected to the other side of the cooling water tank, cooling and circulating the cooling water to form a circulating cooling system. Cooling water flows into the inner cavity of the improved cooling roller 103. The auxiliary pressing roller 102 and the outer wall of the improved cooling roller 103 abut against each other and rotate relative to each other, thereby pressing the molten material into a film. Heat exchange occurs between the cooling water and the calendered film on the outer wall, achieving cooling. (Refer to...) Figure 4 The improved cooling roller 103 with groove assembly 1031 can prepare a first film 1 and / or a second film 2 with plastic film grooves 6 during the calendering process, and finally be wound into a film by winding roller 104. By adopting such a groove extrusion device 10, the groove extrusion device 10 has a simple structure and a simple processing technology, which can facilitate the production of films with plastic film grooves 6. Therefore, it can be used in conjunction with the venting assembly 3 to facilitate venting, which can achieve the technical effects of labor saving and convenient operation. It can also ensure the shape of the buffer air bag after venting, so as not to affect the next use and improve the user experience.

[0075] In this embodiment, by adopting such a manufacturing process, the cushioning air bag can be customized according to the actual application scenario and the number of times it needs to be reused. The number of adhesive components arranged corresponds to the number of times the cushioning air bag can be reused. The number of times the cushioning air bag can be reused can be selected according to the actual application scenario conditions such as product weight, strength, and logistics conditions, which provides greater flexibility and scenario adaptability.
