Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically a waterproof packaging device for paper product processing. Background Technology

[0002] In the paper processing industry, paper products (such as books, documents, and packaging paper) are highly susceptible to external moisture and humid environments during transportation and storage, leading to paper becoming damp, deformed, and moldy, which seriously affects the quality and performance of the paper products. To ensure the quality of paper products during circulation, waterproof packaging equipment has become an indispensable supporting equipment for paper processing enterprises. With the booming development of the logistics industry and the increasing requirements for environmental protection and recycling, higher demands have been placed on the waterproof performance, durability, and recyclability of waterproof packaging equipment, driving continuous innovation and upgrading of such equipment.

[0003] Existing waterproof packaging devices for paper product processing are partially made of plastic sheets. These packaging devices typically possess waterproof, wear-resistant, and corrosion-resistant properties. They are foldable and stackable, have strong load-bearing capacity, and are not easily deformed. The material is mostly PP polypropylene, which can be repeatedly recycled and has a service life of about 3 years, falling into the category of recyclable logistics packaging boxes. In practical applications, this device achieves the closing and sealing of the box door through box structure design and methods such as magnetic adsorption, thereby achieving the purpose of waterproof protection. It is widely used in the transportation and storage of paper products, providing a certain degree of waterproof protection for paper products.

[0004] The existing waterproof packaging device for paper products has significant defects during use. During closing, the inner tongue can easily enter the box due to excessive force. This can prevent the magnets on the outer and inner tongues from attracting each other, negatively impacting the protective effect of the packaging. Especially after prolonged use, the inner tongue is difficult to maintain at a fixed position after rotating 90 degrees, easily rotating directly into the box during closing, failing to achieve an effective seal and providing reliable waterproof protection for paper products. Therefore, improvements are urgently needed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a waterproof packaging device for paper product processing, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof packaging device for paper product processing, comprising a box body, wherein the box body is provided with an inner tongue and an outer tongue, a second magnet is installed on the inner tongue, and a first magnet that is magnetically compatible with the second magnet is installed on the outer tongue, and a pull tab is also connected to the inner tongue, wherein a magnetic strip is embedded in the top of the pull tab and the magnetic strip is magnetically compatible with the first magnet on the outer tongue, and the pull tab is used to limit the excessive rotation of the inner tongue into the box body when it is folded, so as to ensure that the second magnet and the first magnet can be stably attracted;

[0007] The inner tongue is provided with a first waterproof structure, and the outer tongue is provided with a second waterproof structure. The second waterproof structure works in conjunction with the first waterproof structure to enhance the waterproof effect of the inner and outer tongues.

[0008] By adopting the above technical solution, the pull tab is used to limit the excessive rotation of the inner tongue into the box when it is folded. The magnetic strip at the top of the pull tab is attracted to the magnet to further fix the position of the inner tongue, which solves the problem that the inner tongue is easily misaligned in the traditional device, causing the magnet to fail to attract and the seal to fail. The first waterproof structure of the inner tongue and the second waterproof structure of the outer tongue work together to enhance the waterproof effect.

[0009] Furthermore, the first waterproof structure includes a rubber pad installed on the outer wall of the inner tongue. The rubber pad has an "I" shape and fits tightly against the outer tongue when the outer tongue is closed, forming two physical barriers to prevent rainwater from seeping in.

[0010] By adopting the above technical solution, the inner tongue and outer tongue are tightly fitted when the inner tongue is closed, and two physical waterproof barriers are formed on both sides of the rubber pad. This effectively prevents rainwater from seeping into the box from the gap between the inner tongue and outer tongue, which greatly improves the waterproof reliability of the gaps compared to a single sealing structure.

[0011] Furthermore, the second waterproof structure includes a sealing strip installed on the end face of the outer tongue, and the outer tongue is provided with two sets. After the two sets of outer tongues are closed, sealing strips are installed on the adjacent end faces. The two sets of sealing strips are squeezed against each other when the outer tongues are closed to fill the gap between the two sets of outer tongues.

[0012] By adopting the above technical solution, the path of rainwater infiltration is blocked at the splicing point of the outer tongue, thus solving the problem of water easily entering through the splicing gap of the outer tongue in traditional devices.

[0013] Furthermore, the second waterproof structure includes a guide strip installed on the bottom side of the outer tongue, and the outer wall of the guide strip near the outer tongue has an outwardly inclined slope design to guide rainwater on the side wall of the outer tongue.

[0014] By adopting the above technical solution, rainwater is prevented from flowing back to the sealing gap below the outer tongue, reducing the contact between rainwater and the sealing part from the source and reducing the risk of rainwater infiltration.

[0015] Furthermore, the pull tab is provided with a groove, which is used for the user to apply force with their hand to pull the pull tab to adjust the position of the inner tongue.

[0016] By adopting the above technical solution, a convenient point of force is provided for the user to apply force with their hands, making it easy to pull the tab to adjust the position of the inner tongue. Whether it is to limit the excessive rotation of the inner tongue or to pull the inner tongue when opening the box later, no tools are needed, making the operation simple and labor-saving.

[0017] Furthermore, the box body, inner tongue, and outer tongue are all made of PP polypropylene material.

[0018] By adopting the above technical solutions, PP polypropylene material is not easily deformed, can maintain the structural stability of the device for a long time, ensure that the sealing and waterproof effect does not decrease significantly with the number of uses, and reduce packaging costs.

[0019] Furthermore, the rubber pad has a thickness of 1-5mm, and the edge of the rubber pad is flush with the edge of the inner tongue, ensuring that the rubber pad can completely cover the contact area between the inner and outer tongues.

[0020] By adopting the above technical solution, the rubber pad is guaranteed to have sufficient elasticity to fit tightly against the outer tongue, forming an effective waterproof barrier, further ensuring the comprehensiveness and reliability of waterproofing at the gaps, and preventing rainwater from seeping into the uncovered areas.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention uses a pull tab to limit the excessive rotation of the inner tongue into the box body, and works with magnet one, magnet two, and the pull tab magnetic strip to achieve stable adsorption between the inner and outer tongues, avoiding the sealing failure problem caused by misalignment of the inner tongue in traditional devices. The "I"-shaped rubber pad forms two physical waterproof barriers, the outer tongue sealing strip fills the splicing gap, and the guide strip guides rainwater away from the box body. The multiple waterproof structures work together to enhance the waterproof effect. Moreover, the box body, inner tongue, and outer tongue are made of PP polypropylene material, which is recyclable. It provides continuous and reliable waterproof protection for the transportation and storage of paper products, while also taking into account environmental protection and durability, and is suitable for the packaging needs of the paper product processing industry.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure;

[0032] A waterproof packaging device for paper product processing, such as Figure 1 - Figure 6 As shown, it includes components such as housing 1, inner tongue 2, outer tongue 3, first waterproof structure, second waterproof structure, and pull tab 7;

[0033] Among them, box 1 is the core storage structure of the packaging device, used to store paper products (such as books, documents, packaging paper, etc.). It is made of PP polypropylene material, which has waterproof, wear-resistant and corrosion-resistant properties. It can also be folded and stacked, has a strong load-bearing capacity, and has a service life of about 3 years. It belongs to the category of recyclable logistics packaging boxes and can meet the protection needs of long-term transportation and storage of paper products.

[0034] Meanwhile, the box 1 is provided with an inner tongue 2 and an outer tongue 3. The inner tongue 2 and the outer tongue 3 work together to seal the box 1 and prevent external moisture from entering.

[0035] Specifically, in this embodiment, a magnet 2 5 is installed on the inner tongue 2, and a magnet 4 is installed on the outer tongue 3. The magnet 4 and the magnet 2 5 are magnetically compatible, and the inner tongue 2 and the outer tongue 3 are tightly attached by magnetic adsorption, which is convenient for opening and closing and can be used repeatedly. A pull tab 7 is also fixedly installed on the inner tongue 2. The pull tab 7 is used to limit the inner tongue 2 from rotating excessively into the box 1 when it is folded, and to ensure that the magnet 2 5 and the magnet 4 can be stably adsorbed.

[0036] Secondly, a magnetic strip is embedded inside the top of the pull tab 7. This magnetic strip is magnetically matched with the magnet 4 on the outer tongue 3. When the inner tongue 2 is folded to a 90° position perpendicular to the side wall of the box 1, the pull tab 7 can fit against the outer wall of the outer tongue 3. The position of the inner tongue 2 is further fixed by the attraction between the magnetic strip and the magnet 4. Furthermore, a pull groove 8 is provided on the pull tab 7. The pull groove 8 is used for the user to apply force with their hand to easily pull the pull tab 7 to adjust the position of the inner tongue 2, thereby improving the ease of operation.

[0037] For example, a first waterproof structure is provided on the inner tongue 2. The first waterproof structure is used to enhance the waterproof effect of the inner tongue 2. It includes a rubber pad 6 installed on the outer wall of the inner tongue 2. The rubber pad 6 has an "I" shape and a thickness of 1-5mm. Its edge is flush with the edge of the inner tongue 2, ensuring that the rubber pad 6 can completely cover the contact area between the inner tongue 2 and the outer tongue 3. When the outer tongue 3 is closed, the rubber pad 6 is tightly fitted to the outer tongue 3. The protrusions on both sides of the "I" shape form two physical barriers to prevent rainwater from seeping in, greatly reducing the risk of rainwater seeping in from the gap between the inner tongue 2 and the outer tongue 3.

[0038] For example, a second waterproof structure is provided on the outer tongue 3. The second waterproof structure cooperates with the first waterproof structure to further improve the overall waterproof performance. The second waterproof structure includes a sealing strip 9 and a guide strip 10.

[0039] Among them, the sealing strip 9 is installed on the end face of the outer tongue 3. Since there are two sets of outer tongue 3, sealing strip 9 is installed on the end faces of the two sets of outer tongue 3 after they are closed. When the outer tongue 3 is closed, the two sets of sealing strip 9 are squeezed against each other, which can fill the gap between the two sets of outer tongue 3 and prevent rainwater from seeping in from the joint of the outer tongue 3.

[0040] Secondly, the guide strip 10 is installed on the bottom side of the outer tongue 3. The outer wall of the guide strip 10 near the outer tongue 3 is designed with an outward inclined slope. This inclined structure can guide the rainwater on the side wall of the outer tongue 3 to flow away from the box 1, while preventing the rainwater from flowing back to the bottom of the outer tongue 3, thus reducing the probability of rainwater contacting the sealing gap from the source.

[0041] Through the coordinated operation of the aforementioned components, this waterproof packaging device for paper product processing requires the assembly and sealing of box 1 before the paper products are loaded. The entire process achieves efficient waterproofing through the coordinated action of multiple components. The specific process is as follows:

[0042] Before packing the paper products, first seal the bottom of the box 1; fold a set of inner tongues 2 at the bottom of the box 1 into the box 1, then pull the pull tab 7 on the inner tongue 2. At the same time, the magnetic strip embedded in the top of the pull tab 7 restricts the inner tongue 2 from rotating excessively by the pulling force of the pull tab 7, so as to prevent it from completely sinking into the box 1 and ensure that the inner tongue 2 remains at a 90° angle to the side wall of the box 1 after being folded.

[0043] Next, fold the outer tongue 3 towards the inner tongue 2. The magnet 5 on the outer wall of the inner tongue 2 and the magnet 4 on the inner wall of the outer tongue 3 are attracted by magnetism, automatically align and fit together, forming a preliminary fixation. Then fold another set of outer tongues 3 in the same way, so that both sets of outer tongues 3 are tightly attached to the inner tongue 2.

[0044] Finally, the pull tab 7 is attached to the outer wall of the outer tongue 3, and the magnetic strip at the top of the pull tab 7 is magnetically attracted to the magnet 4 of the outer tongue 3, further fixing the relative position of the inner tongue 2 and the outer tongue 3.

[0045] After the bottom of the box 1 is sealed, the processed paper products are placed smoothly inside the box 1, ensuring that the paper products do not exceed the edge of the box 1 to avoid affecting the sealing effect of the top. Then, the bottom assembly process is repeated. First, the inner tongue 2 at the top of the box 1 is folded, and the pull tab 7 is pulled to limit its excessive rotation. Then, the two sets of outer tongues 3 are folded in sequence and fixed by the attraction force of magnet 1 4 and magnet 2 5. Finally, the pull tab 7 is attached to the outer tongue 3 to complete the overall sealing of the box 1 and form basic protection for the paper products inside.

[0046] During the sealing process of the box 1, the "I"-shaped rubber pad 6 installed on the outer wall of the inner tongue 2, when it is in contact with the outer tongue 3, the two sides of the rubber pad 6 make close contact with the inner tongue 2 and the outer tongue 3 respectively, forming two physical barriers to prevent rainwater from seeping into the interior of the box 1 from the gap between the inner and outer tongues, and greatly improving the sealing performance of the gap.

[0047] After the two sets of outer tongues 3 are closed, the sealing strips 9 on their adjacent end faces are squeezed and deformed to fill the gap between the outer tongues 3, preventing a large amount of rainwater from seeping in from the splice of the outer tongues 3, further enhancing the end face sealing effect. At the same time, the inner wall of the guide strip 10 at the bottom of the side of the outer tongue 3 is designed with an outward sloping surface. When rainwater falls on the side wall of the outer tongue 3, the guide strip 10 will guide the rainwater away from the box 1. At the same time, the sloping structure prevents rainwater from flowing back to the gap below the outer tongue 3 during the guidance process, reducing the probability of rainwater contacting the sealing part from the source and maximizing the waterproof performance.

[0048] When paper products need to be removed, the operation is reversed; first, peel off the pull tab 7 to overcome the attraction between magnet 4 and magnet 5, then flip the two sets of outer tongues 3 outward, and then pull the inner tongue 2 out of the box 1 through the pull tab 7 to open the box 1; the box 1 can be reused multiple times for paper product packaging, taking into account both environmental protection and practicality. This utility model effectively solves the problems of easy misalignment of the inner tongue and unreliable sealing in traditional devices, providing continuous and stable waterproof protection for the transportation and storage of paper products;

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
