[0022] Reference Figure 1-2 As shown, a high-hardness industrial packaging paper tube comprises an outer paper tube 1, an inner paper tube 2, an adhesive layer 3, an outer protective layer 4 and an inner protective layer 5, wherein the outer paper tube 1 and the inner paper tube 2 are fixedly connected by the adhesive layer 3, the outer side of the outer paper tube 1 is provided with the outer protective layer 4, the inner side of the adhesive layer 3 is provided with the inner protective layer 5, the inner side of the adhesive layer 3 is fixedly connected with a reinforcing ring 6, the inner side of the reinforcing ring 6 is fixedly connected with a plurality of groups of reinforcing rods 7, and the plurality of reinforcing rods 7 are evenly distributed in a ring shape inside the reinforcing ring 6. The inner paper tube 2 and the outer paper tube 1 are connected into a whole by the adhesive layer 3, which effectively improves the strength, hardness, toughness and compression resistance of the paper tube as a whole, so that the paper tube as a whole is not easy to bend and break, thereby improving the service life of the paper tube as a whole. At the same time, the reinforcing ring 6 and the reinforcing rod 7 fixedly connected to the inner side of the inner paper tube 2 can support the paper tube as a whole, further strengthen the compression resistance of the paper tube as a whole, so that the paper tube as a whole is not easy to bend and break, thereby improving the service life of the paper tube as a whole.

[0023] Specifically, in this embodiment, the outer paper tube 1 is made of kraft paper, and a first steel mesh 101 is provided inside the outer paper tube 1. The steel mesh is fixed in the pulp sheet when it is pressed into paperboard, ensuring that the steel mesh is evenly distributed in the wall of the paper tube to provide balanced support and strength, preventing the paper tube from deforming or breaking when subjected to external force or pressure, and providing additional tensile strength so that the paper tube can withstand greater weight and pressure.

[0024] Specifically, in this embodiment, the raw material for making the inner paper tube 2 is corrugated paper, and a second steel wire mesh 201 is arranged inside the inner paper tube 2, wherein the corrugated paper has a high compression strength and impact resistance due to its wavy structure, and can better withstand external pressure and impact, so that the paper tube has good bearing capacity and protection performance, and is suitable for transporting and storing various items. Kraft paper is mainly used for the outer layer of the paper tube, providing the paper tube with beautiful appearance and surface protection, and has high tensile strength and tearing strength. When the paper tube needs to obtain higher strength, thicker corrugated paper can be selected or the number of layers of the paper tube can be increased to improve the overall bearing capacity.

[0025] Specifically, in this embodiment, the outer protective layer 4 includes a first wear-resistant layer 401 and a first waterproof layer 402. The first waterproof layer 402 is coated and bonded on the outer side wall of the outer paper tube 1, and the first wear-resistant layer 401 is coated on the outer side of the first waterproof layer 402.
