[0029] The chemical fiber paper tube body 1 includes two body layers 11, the opposite sides of the two body layers 11 are provided with a reinforcing layer 12, and the opposite sides of the two body layers 11 are provided with a barrier layer 13, and the outer side of the surface barrier layer 13 is provided with a moisture-proof layer 14.

[0030] In the embodiment: by setting the chemical fiber paper tube body 1 is composed of the reinforcing layer 12, the body layer 11, the barrier layer 13 and the moisture-proof layer 14, the barrier layer 13 can directly block the oil stain from contacting the body layer 11, the reinforcing layer 12 helps to strengthen the overall structure to prevent performance degradation caused by oil absorption, and the moisture-proof layer 14 can also assist in preventing the oil stain and other pollutants in the external environment from entering the chemical fiber paper tube body 1 to some extent, effectively protecting the performance of the chemical fiber paper tube body 1 itself, prolonging its service life, and avoiding pollution to the chemical fiber products packaged or supported, ensuring product quality.

[0031] Specifically, as shown in Figure 5 The reinforcing layer 12 is composed of carbon fibers and is wound on the surface of the inner body layer 11.

[0032] Specifically, as shown in Figure 5 The barrier layer 13 is composed of oil-proof paper and is spirally arranged on the opposite sides of the two body layers 11.

[0033] Specifically, as shown in Figure 5 The moisture-proof layer 14 is composed of moisture-proof kraft paper and is spirally wound on the surface of the surface barrier layer 13.

[0034] Specifically, as shown in Figure 5 The opposite sides of the two body layers 11 are uniformly coated with epoxy resin, and the carbon fibers are spirally adhered between the opposite sides of the two body layers 11 by the epoxy resin.

[0035] In the embodiment: by setting the reinforcing layer 12 composed of carbon fibers bonded between the two main layers 11 by epoxy resin, the carbon fibers have extremely high strength and modulus advantages, and the winding on the surface of the main layer 11 can significantly enhance the overall strength of the reinforced paper tube body 1, making it more flexible when subjected to pressure and less likely to deform or break. By setting the barrier layer 13 composed of oil-proof paper, the low permeability and oil resistance of the oil-proof paper can effectively prevent external oil from contacting the main layer 11, greatly reducing the possibility of the chemical fiber paper tube body 1 absorbing oil, protecting the internal structure of the chemical fiber paper tube body 1 from oil erosion, maintaining the original performance of the chemical fiber paper tube body 1, prolonging its service life, and preventing oil from contaminating the packaged or supported chemical fiber products, ensuring that the product quality meets the requirements. And by setting the moisture-proof layer 14 composed of moisture-proof kraft paper, the moisture-proof kraft paper can effectively block the moisture in the external environment from entering the chemical fiber paper tube body 1, preventing the chemical fiber paper tube body 1 from being affected by moisture.

[0038] In the embodiment: by setting the arc-shaped protrusions 6 and the elastic members 7, when the chemical fiber paper tube body 1 is subjected to external pressure, the arc-shaped protrusions 6 can first contact and disperse part of the pressure, playing a preliminary buffering role, and the elastic members 7 can further deform under pressure to absorb and buffer the remaining pressure, effectively reducing the direct pressure on the chemical fiber paper tube body 1, preventing the chemical fiber paper tube body 1 from deforming or breaking due to excessive pressure, improving the pressure resistance of the chemical fiber paper tube body 1, and better protecting the structural integrity of the chemical fiber paper tube body 1 when facing larger pressure. By setting the retaining ring 8, it can be ensured that the structure of the support cylinder 4 and the pressure-bearing cylinder 5 will not loosen or separate due to external force during use of the chemical fiber paper tube body 1.

[0039] Specifically, as shown in Figure 4 , the surface of the support ring 10 is in contact with the inner wall of the chemical fiber paper tube body 1, and the inner wall of the inner cylinder 3 is provided with a thread that matches the thread on the surface of the support ring 10.

[0040] In the embodiment: by setting the support ring 10, the support ring 10 provides an additional support point for the inside of the chemical paper tube body 1, when the chemical paper tube body 1 is subjected to external pressure, especially in the case of possible pressure concentration in the middle of the chemical paper tube body 1, the support ring 10 can share part of the pressure, play a role in relieving pressure concentration, and the threaded connection between the support rod 2 and the inner cylinder 3 makes the connection between the support rod 2 and the inner cylinder 3 more stable and reliable, during the use of the chemical paper tube body 1, no matter what external force is applied, the support rod 2 and the inner cylinder 3 can maintain a close connection state, and will not appear loose, dislocation and other conditions.
