[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a self-positioning paper tube proposed by this utility model is provided in conjunction with the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions. Terms such as "center," "side," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and do not indicate or imply that a self-positioning paper tube or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model, but are only used to conveniently and clearly assist in explaining the purpose of the embodiments of this utility model. Please refer to the accompanying drawings to make the objectives, features, and advantages of this utility model more apparent and understandable.

[0027] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0028] The following describes the specific structure of a self-positioning paper tube:

[0029] Please see Figure 1 and Figure 2 In this embodiment, the self-positioning paper tube includes a positioning tube 1, a winding tube 2, and a positioning element 3. The winding tube 2 is movably mounted on the positioning tube 1 via the positioning element 3. Preferably, the positioning element 3 is made from the edge ring of a waste paper tube, which conforms to the concept of resource conservation while reducing production costs.

[0030] For further information, please refer to [link / reference]. Figure 4The positioning tube 1 is uniformly provided with at least one set of first holes 101 along a first direction. Each set of first holes 101 is collinear along the first direction and penetrates the positioning tube 1 along the setting direction. Preferably, in this embodiment, the opening of the first holes 101 all passes through the center of the positioning tube 1. The positioning tube 1 has two sets of first holes 101, which can be adaptively adjusted according to different customer products. The cross-section of the positioning member 3 matches the first hole 101, allowing the positioning member 3 to freely enter and exit the first hole 101 to achieve positioning support. In this embodiment, the first direction is the direction of the height of the positioning tube 1.

[0031] For further information, please refer to [link / reference]. Figure 5 and Figure 6 The winding tube 2 has a second hole 201, which fits the outer diameter of the positioning tube 1, so that the winding tube 2 can be adapted to the positioning tube 1 after being wound on its outer surface and then stacked on the positioning tube 1.

[0032] Furthermore, grooves 202 are uniformly arranged in a ring around the opening of the second hole 201, and the grooves 202 penetrate the winding tube 2 along the setting direction. Please continue reading. Figures 1 to 3 The positioning element 3 is fitted into the slot 202, and the height of the positioning element 3 along the first direction is greater than the depth of the two slots 202. This ensures that the two adjacent winding tubes 2 do not contact each other during the stacking process, effectively avoiding deformation of the end face of the winding tube 2 due to contact during storage or transportation.

[0033] For further information, please refer to [link / reference]. Figure 7 The positioning member 3 has symmetrically arranged limiting portions 301 on its surface. These limiting portions 301 cooperate with the winding tube 2, and the length of the positioning member 3 is greater than the outer diameter of the winding tube 2. Preferably, the limiting portions 301 restrict the length of the positioning member 3 extending beyond both ends of the winding tube 2, effectively ensuring that the center of the positioning member 3 is collinear with the center of the end faces of the positioning tube 1 and the winding tube 2 in the first direction. Furthermore, the length of the positioning member 3 protruding beyond both ends of the winding tube 2 provides a reference for the thickness of the winding on the surface of the winding tube 2, facilitating the operator's production work.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
