[0002] Conventional paper tubes are prone to problems such as fading, burrs, insufficient pressure resistance, difficulty in tube removal, and long or short tubes. During the rainy season, paper tubes are prone to deformation and insufficient pressure resistance due to moisture. Users are required to monitor the condition of paper tubes in real time and test them during use to ensure the normal use of paper tubes. If paper tubes are found to be too long or too short or deformed, they need to be shipped back to the supplier for baking or new tubes are sent, which increases production costs and may also extend product delivery time, resulting in a delay in delivery.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] like Figure 1-Figure 3 As shown, the recyclable grafting tube of this embodiment includes a plastic tube 1, a paper tube 2, a groove 3 and a connecting rod 4. An annular hole 11 is opened inside the plastic tube 1, one end of the connecting rod 4 is fixed to the inside of the tube wall of the paper tube 2, and the other end of the connecting rod 4 extends to the inside of the annular hole 11; the plastic tube 1, the connecting rod 4 and the paper tube 2 are fixed by an adhesive; the groove 3 is opened in the middle of the outer wall of the paper tube 2.
[0024] The utility model uses a plastic tube 1 and a paper tube 2 to be grafted and fixed, which can reduce the use of paper raw materials, reduce costs, and facilitate reuse. A connecting rod 4 is arranged inside the paper tube 2 and the plastic tube 1, and the connecting rod 4 can enhance the structural strength of the paper tube 2 and prevent the paper tube 2 from bending and being damaged; by applying adhesive on the surface of the connecting rod 4, the connection between the paper tube 2 and the plastic tube 1 can also be made stronger. An annular hole 11 is opened inside the plastic tube 1, and the annular hole 11 can reduce the overall weight of the plastic tube 1 and can also be fixed with the connecting rod 4.
[0025] Furthermore, the plastic tube 1 and the paper tube 2 have the same thickness.
[0026] Furthermore, the plastic tube 1 and the paper tube 2 use solvent-free polyurethane or polyvinyl acetate emulsion as an adhesive.
[0027] Solvent-free polyurethane and polyvinyl acetate emulsions are environmentally friendly materials with strong peeling power and low energy consumption.
[0028] Furthermore, melamine resin is added to the adhesive.
[0029] When the yarn is wound, tension is generated, which causes a clamping effect on the paper tube 2, causing the paper tube 2 to slowly creep and cause the paper tube 2 to rupture. Therefore, melamine resin can be added to the adhesive to reinforce the paper tube 2 so that the paper tube 2 has the function of resisting deformation.
[0030] The method of using the utility model is:
[0031] A certain number of plastic tubes 1 and paper tubes 2 are selected as needed, and then a connecting rod 4 of appropriate length is selected. The paper tube 2 and the plastic tube 1 are bonded and fixed by applying adhesive at the connection between the plastic tube 1 and the paper tube 2 and on the surface of the connecting rod 4. After the adhesive dries, the fixation of the paper tube 2 and the plastic tube 1 is completed. Then the yarn can be stuffed into the embedding groove 3, and the yarn can be wound by using a machine to wind the grafting tube.
[0032] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
