[0015] In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features. In the description of the utility model, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically limited.
[0016] In the present application, unless otherwise expressly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship of two elements, unless otherwise expressly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0017] In the present application, unless otherwise expressly specified and limited, the first feature is "on" or "under" the second feature. The first and second features can be in direct contact, or the first and second features can be in indirect contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" the second feature can be directly above or obliquely above the first feature, or only indicate that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature can be directly below or obliquely below the first feature, or only indicate that the horizontal height of the first feature is less than that of the second feature.
[0018] Referring to the drawings Figure 1 The high-pressure-resistant paper tube with a reinforcing structure in the embodiment comprises a paper tube body, the paper tube body is wound by multiple layers of paper, the multiple layers of paper comprise inner layer paper 1, middle layer paper 2 and outer layer paper 3, the middle layer paper 2 is internally provided with a reinforcing fiber layer, the outer surface of the outer layer paper 3 is provided with a buffer layer 4, and the inner wall of the paper tube body is provided with an annular reinforcing rib 5.
[0019] The paper tube body in the embodiment is composed of the inner layer paper 1, the middle layer paper 2 and the outer layer paper 3 to form a multi-layer structure, the wall thickness and structural complexity of the paper tube are increased, so that the paper tube can withstand greater pressure. The reinforcing fiber layer (made of glass fiber, thickness 8-15 μm) in the middle layer paper 2 further significantly improves the pressure resistance of the paper tube. The glass fiber has the characteristics of high strength and high modulus, and can effectively share and transmit the load when the paper tube is subjected to pressure, prevent the relative slip and deformation between the paper layers, thereby greatly improving the axial and radial compressive strength of the paper tube, so that it can adapt to more stringent bearing requirements, such as maintaining structural stability when winding heavy coiled materials or bearing greater external extrusion.
[0020] The annular reinforcing ribs 5 provide internal support, and the annular reinforcing ribs (2mm thick) arranged on the inner wall of the paper tube body provide additional internal support structure for the paper tube. These annular reinforcing ribs can effectively resist the inward deformation tendency of the paper tube when subjected to pressure, enhancing the overall rigidity of the paper tube. When subjected to axial pressure, the annular reinforcing ribs act as a solid framework, evenly distributing the pressure to the entire inner wall of the paper tube, reducing the occurrence of local stress concentration, greatly improving the collapse resistance of the paper tube, and ensuring the integrity and reliability of the paper tube under high load conditions.
[0021] The setting of the buffer layer 4 (made of rubber or foam material, thickness of 3-4mm) can effectively absorb and dissipate energy, reduce the impact of impact force on the internal structure of the paper tube and the packaged goods, and play a good protection role. For example, when encountering bumps or collisions during transportation, the buffer layer can reduce the risk of damage to the paper tube due to vibration, ensuring the safe transportation of the packaged products. On the other hand, the buffer layer can also adjust the surface hardness and friction of the paper tube to a certain extent, making it more stable when in contact or stacked with other objects, reducing accidental damage caused by friction or sliding.
[0022] The anti-slip pattern on the outer wall of the paper tube body (raised or recessed strip or mesh structure, depth or height of 1-1.5mm) can increase the friction between the hand or other handling tools and the surface of the paper tube, allowing the operator to hold the paper tube more stably, reducing the safety hazards caused by slipping, and improving the convenience and safety of operation. At the same time, when the paper tube needs to be matched or fixed with other components, the anti-slip pattern can also help to enhance the connection stability between the paper tube and the adjacent components, preventing the relative sliding from affecting the performance of the overall structure.
[0023] The above embodiments are only preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
