Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0035] The utility model provides a kind of compression-resistant and deformation-resistant seamless paper tube as Figures 1-4 As shown in a kind of compression-resistant and deformation-resistant seamless paper tube, including: waterproof composite layer 1, waterproof composite layer 1 is hollow cylindrical;Compression-resistant composite layer 2, compression-resistant composite layer 2 is annular array and is set to the outside of waterproof composite layer 1;Wear-resistant composite layer 3, wear-resistant composite layer 3 is set to the outside of waterproof composite layer 1, and compression-resistant composite layer 2 is set to the gap between waterproof composite layer 1 and wear-resistant composite layer 3.

[0036] The compression-resistant composite layer 2 comprises: a triangular support structure 21, which is triangularly supported outside the waterproof composite layer 1; and an arc-shaped support plate 22, which is connected between adjacent triangular support structures 21 and has two ends connected to the middle of the triangular support structure 21. The triangle is one of the most stable geometric shapes in nature and has excellent compression resistance and shear resistance. The annular array of the triangular support structure 21 allows the triangular support structure 21 to be triangularly supported between the waterproof composite layer 1 and the wear-resistant composite layer 3, so that external forces can be evenly dispersed through the triangular support structure 21, significantly improving the compression resistance of the paper tube. The triangular support of the triangular support structure 21 can absorb and disperse impact energy, reduce direct damage to the paper tube by external forces, reduce stress concentration in the paper tube during long-term use, and prolong the service life of the paper tube. The two ends of the arc-shaped support plate 22 are located between two triangular support structures 21, thereby facilitating the stability and strength of the triangular support structure 21.

[0037] The triangular support structure 21 comprises: a triangular support frame 211, which is triangularly arranged, with two support points connected to the waterproof composite layer 1 and the other support point connected to the wear-resistant composite layer 3; a reinforcing rib 212, which is supported on the inner side of the triangular support frame 211 and is arranged in a V shape; and a support pipe 213, which is tangentially arranged between the triangular support frame 211 and the reinforcing rib 212. The symmetrical arrangement of the two triangular support frames 211 facilitates the formation of a triangular support and improves the compression resistance and deformation resistance of the seamless paper tube. The reinforcing rib 212 supports the two triangular support frames 211 to improve the compression resistance of the triangular support frame 211. The hollow structure of the support pipe 213 provides elastic support for the triangular support frame 211, making the triangular support frame 211 stronger.

[0038] The waterproof composite layer 1 comprises: a compression-resistant support layer 11 in the shape of a hollow cylinder; a compression-resistant filling layer 12 covering the outside of the compression-resistant support layer 11; and a waterproof kraft paper 13 adhered to the inside of the compression-resistant support layer 11. The outer wall of the compression-resistant support layer 11 is connected with a plurality of first reinforcing strips 14 at equal intervals, and the first reinforcing strips 14 are filled in the inside of the compression-resistant filling layer 12. The compression-resistant support layer 11 is made of high-density polyethylene (HDPE) or polypropylene (PP) film with a thickness of 0.1-0.2 mm, which can provide rigid support for the inner wall and prevent the inner wall from collapsing when the paper tube is under pressure. The compression-resistant filling layer 12 is made of expanded polyethylene (EPE) or polyurethane foam with a thickness of 1.0-3.0 mm, which can provide cushioning and compression resistance to reduce deformation and stress concentration of the paper tube under pressure. The waterproof kraft paper 13 can be used for waterproof treatment of the inner side of the paper tube. The first reinforcing strips 14 can be used to strengthen the bending resistance of the paper tube.

[0039] The wear-resistant composite layer 3 comprises: a reinforced fiber layer 31 in the shape of a hollow cylinder; a compression-resistant filling material 32 covering the outside of the reinforced fiber layer 31; a second reinforcing strip 33 in the shape of a ring array filled in the inside of the compression-resistant filling material 32; a structural reinforcement layer 34 adhered to the outside of the compression-resistant filling material 32; and a surface treatment layer 35 provided on the outside of the structural reinforcement layer 34. The reinforced fiber layer 31 is made of glass fiber or carbon fiber composite material with a thickness of 0.3-0.5 mm, which can improve the overall strength and impact resistance of the paper tube and prevent deformation or damage caused by external forces. The compression-resistant filling material 32 is made of expanded polyethylene (EPE) or polyurethane foam with a thickness of 1.0-2.0 mm, which can provide cushioning and compression resistance to reduce impact and vibration of the paper tube during transportation or use. The second reinforcing strip 33 is parallel to the axis of the paper tube, which can strengthen the bending resistance of the paper tube. The structural reinforcement layer 34 is made of paper-based honeycomb structure or aluminum honeycomb structure with a thickness of 2.0-5.0 mm, which can provide high strength and compression resistance through the honeycomb structure. The honeycomb structure provides high compression strength and rigidity through its unique hexagonal cell design, which can effectively disperse external forces and prevent deformation or collapse of the paper tube under heavy load or stacking conditions, while reducing the overall weight. The surface treatment layer 35 is made of nano-silicon dioxide or graphene-based coating with a thickness of 0.01-0.02 mm, which can improve the surface hardness and compression resistance of the paper tube through the nano-scale surface structure, while providing waterproof and anti-fouling functions.
