Description

Technical Field

[0001] The present application relates to the technical field of industrial paper tubes, and specifically to a high-strength, pressure-resistant industrial paper tube. Background Art

[0002] In the industrial packaging sector, industrial paper tubes are widely used across a variety of industries, including paper, textiles, and plastic film, due to their low cost, ease of processing, and recyclability. These paper tubes serve as a crucial packaging tool, primarily used for winding and storing various rolls of material, ensuring the orderliness and integrity of the materials during transportation, storage, and processing.

[0003] Since paper tubes are mainly made of natural materials such as cellulose, there are a large number of micropores and gaps on their surface and inside. These microstructures make it easy for paper tubes to absorb moisture in the air, causing them to become damp, deformed, or even moldy. Once the paper tubes become damp, their strength and stability will drop significantly. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a high-strength, pressure-resistant industrial paper tube with advantages such as moisture-proof, which solves the problems raised in the background technology.

[0005] To achieve the above objectives, the present application provides the following technical solution: a high-strength, pressure-resistant industrial paper tube, comprising an outer tube, an outer tube disposed inside the outer tube, the outer tube and the inner tube being coaxial, a spiral reinforcement rib disposed on the outer surface of the inner tube, the spiral reinforcement rib in contact with the inner wall of the outer tube, the cross-section of the spiral reinforcement rib being funnel-shaped;

[0006] A support assembly is provided inside the inner tube;

[0007] The support assembly includes a central column, a plurality of support rings and a plurality of polyurethane foam rings;

[0008] The outer surface of the outer tube body is provided with a hydrophobic and wear-resistant coating, and a polyethylene film is bonded to the outer side of the hydrophobic and wear-resistant coating.

[0009] The above solution forms a stable support structure by providing spiral reinforcing ribs with a funnel-shaped cross-section on the outer surface of the inner tube and tightly bonding them to the inner wall of the outer tube. This design not only enhances the paper tube's longitudinal compressive strength but also effectively improves its ability to withstand radial pressure through the dispersing effect of the spiral reinforcing ribs. Furthermore, the support components within the inner tube, including a central column, multiple support rings, and a polyurethane foam ring, further enhance the overall strength of the paper tube, enabling it to withstand greater external impact and pressure while ensuring the integrity and stability of the internal material. The outer tube is made by rolling and tightly bonding multiple layers of paper. This multi-layer composite structure effectively reduces gaps and micropores between the sheets, reducing the risk of moisture penetration. Furthermore, the hydrophobic and wear-resistant coating applied to the outer surface of the outer tube and the polyethylene film bonded to the outside further enhance the paper tube's moisture resistance. The polyethylene film not only has excellent waterproof properties but also effectively isolates moisture from the air, preventing the paper tube from deforming due to moisture. The polyurethane foam ring has the function of absorbing moisture, further ensuring a dry environment inside the paper tube.

[0010] Furthermore, the spiral reinforcement ribs are bonded to the outer surface of the inner tube and the inner wall of the outer tube.

[0011] Through the above solution, a stable supporting structure can be formed and the overall strength can be improved.

[0012] Furthermore, the surface of the polyethylene film is provided with anti-slip texture.

[0013] The above solution is used to improve the stability of paper tubes during transportation.

[0014] Furthermore, the central column is bonded to the support ring.

[0015] The above solution can facilitate assembly for users.

[0016] Furthermore, a plurality of the support rings are arranged on the central column at equal intervals.

[0017] Through the above solution, the pressure from the radial direction of the paper tube can be dispersed and withstood, thereby improving the compression resistance of the paper tube.

[0018] Furthermore, each of the polyurethane foam rings is bonded to the central column.

[0019] The above solution not only plays a supporting role, but also has the function of absorbing moisture to prevent the entire structure from being invaded by moisture.

[0020] Furthermore, each of the support ring and the polyurethane foam ring is bonded to the inner wall of the inner tube.

[0021] Through the above solution and the above arrangement, the self-movement of the central column can be effectively avoided and the support stability can be ensured.

[0022] Furthermore, the outer tube is formed by rolling up multiple layers of paper and tightly bonding them.

[0023] The above solution ensures that the outer tube can maintain the stability and integrity of the overall structure when subjected to external pressure and impact.

[0024] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0025] This high-strength, pressure-resistant industrial paper tube forms a stable support structure by arranging spiral reinforcement ribs with a funnel-shaped cross-section on the outer surface of the inner tube and tightly bonding them to the inner wall of the outer tube. This design not only enhances the longitudinal compressive strength of the paper tube, but also effectively improves the paper tube's ability to withstand radial pressure through the dispersing effect of the spiral reinforcement ribs. At the same time, the support components inside the inner tube, including a central column, multiple support rings and a polyurethane foam ring, further enhance the overall strength of the paper tube, enabling it to withstand greater external impact and pressure, ensuring the integrity and stability of the internal material. The outer tube is made of multiple layers of paper rolled up and tightly bonded. This multi-layer composite structure effectively reduces gaps and micropores between the papers, reducing the risk of moisture penetration. In addition, the hydrophobic and wear-resistant coating coated on the outer surface of the outer tube and the polyethylene film bonded to the outside further enhance the moisture-proof performance of the paper tube. The polyethylene film not only has good waterproof properties, but also can effectively isolate moisture in the air to prevent the paper tube from deformation due to moisture. The polyurethane foam ring has the function of absorbing moisture, further ensuring a dry environment inside the paper tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] See also Figure 1 、 Figure 2 and Figure 3 In this embodiment, a high-strength, pressure-resistant industrial paper tube includes an outer tube 1. An inner tube 2 is provided inside the outer tube 1. The outer tube 1 and the inner tube 2 are on the same axis. The outer surface of the inner tube 2 is provided with spiral reinforcement ribs 3, and the spiral reinforcement ribs 3 are in contact with the inner wall of the outer tube 1. The cross-section of the spiral reinforcement ribs 3 is funnel-shaped. The spiral reinforcement ribs 3 are bonded to the outer surface of the inner tube 2 and the inner wall of the outer tube 1, which can form a stable support structure and improve the overall strength. The outer tube 1 is made of multiple layers of paper rolled up and tightly bonded to ensure that the outer tube 1 can maintain the stability and integrity of the overall structure when subjected to external pressure and impact.

[0034] A support assembly 4 is provided inside the inner tube 2 .

[0035] See also Figure 1 、 Figure 3 and Figure 4 The support assembly 4 includes a central column 401, multiple support rings 402 and multiple polyurethane foam rings 403. The central column 401 is bonded to the support rings 402, which can be easily assembled by the user. Multiple support rings 402 are arranged on the central column 401 at equal intervals, which can disperse and withstand the radial pressure from the paper tube, thereby improving the compression resistance of the paper tube. Each polyurethane foam ring 403 is bonded to the central column 401, which not only plays a supporting role, but also has the function of absorbing moisture to prevent the whole from being invaded by moisture.

[0036] See also Figure 1 、 Figure 2 and Figure 3 Each support ring 402 and polyurethane foam ring 403 are bonded to the inner wall of the inner tube 2. Through the above arrangement, the center column 401 can be effectively prevented from moving by itself, ensuring the support stability. The outer surface of the outer tube 1 is provided with a hydrophobic and wear-resistant coating 5. The outer side of the hydrophobic and wear-resistant coating 5 is bonded with a polyethylene film 6. The surface of the polyethylene film 6 is provided with an anti-slip texture to improve the stability of the paper tube during transportation.

[0037] In this embodiment, a high-strength, pressure-resistant industrial paper tube is provided with a spiral reinforcing rib 3 with a funnel-shaped cross section on the outer surface of the inner tube 2, which is tightly bonded to the inner wall of the outer tube 1 to form a stable support structure. This design not only enhances the longitudinal compressive strength of the paper tube, but also effectively improves the paper tube's ability to withstand radial pressure through the dispersion effect of the spiral reinforcing rib 3. At the same time, the support assembly 4 inside the inner tube 2, including the central column 401, multiple support rings 402 and the polyurethane foam ring 403, further enhances the overall strength of the paper tube, enabling it to withstand greater external impact and pressure, ensuring To ensure the integrity and stability of the internal material, the outer tube 1 is made of multiple layers of paper rolled up and tightly bonded. This multi-layer composite structure effectively reduces the gaps and micropores between the papers, reducing the risk of moisture penetration. In addition, the hydrophobic and wear-resistant coating 5 coated on the outer surface of the outer tube 1 and the polyethylene film 6 bonded to the outside further enhance the moisture-proof performance of the paper tube. The polyethylene film 6 not only has good waterproof performance, but also can effectively isolate moisture in the air to prevent the paper tube from being deformed by moisture. The polyurethane foam ring 403 has the function of absorbing moisture, further ensuring a dry environment inside the paper tube.

[0038] The working principle of the above embodiment is as follows: first, the spiral reinforcement ribs 3 on the outer surface of the inner tube 2 are tightly bonded to the inner wall of the outer tube 1 to form a stable support structure, which effectively disperses and resists the longitudinal and radial pressure from the outside and enhances the compressive resistance of the paper tube. Secondly, the central column 401 inside the inner tube 2 is tightly combined with multiple support rings 402 and polyurethane foam rings 403, further improving the overall strength and stability of the paper tube, ensuring that the internal material can still be protected from damage in complex environments. The outer tube 1 is made of multiple layers of paper tightly bonded together, reducing the channels for moisture penetration. At the same time, the hydrophobic and wear-resistant coating 5 coated on the outer surface works together with the polyethylene film 6 to form a waterproof barrier, effectively isolating moisture in the air and preventing the paper tube from being deformed by moisture. The polyurethane foam ring 403 absorbs and discharges internal moisture, keeping the inside of the paper tube dry, and further improving the moisture-proof effect. In summary, the paper tube achieves high-strength compressive resistance and excellent moisture-proof performance through multi-layer protection and reinforcement design.
