Technical Field

[0001] This utility model relates to the field of paper tube technology, and in particular to a spliced ​​resin paper tube. Background Technology

[0002] Resin paper tubes are tubular structures made of high-strength composite materials, the main materials of which include resin and paper.

[0003] Resin paper tubes enhance their performance by impregnating paper with resin, making them more stable and less prone to deformation during use. However, when the length of a single resin paper tube is insufficient, two resin paper tubes need to be spliced ​​together. But the splice joint of the two resin paper tubes is not supported enough, which makes it easy for deformation to occur when the splice joint is subjected to single-point compression. To address this, we propose a spliced ​​resin paper tube. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figures 1-3The splicing resin paper tube shown includes a tube body 101 and a splicing mechanism. The tube body 101 is a composite structure. The composite structure of the tube body 101 makes the tube body 101 more pressure resistant, thereby making the tube body 101 less prone to deformation during use.

[0021] In a preferred embodiment, a splicing mechanism is disposed between two tubes 101. The splicing mechanism includes a first metal tube 202. A first annular groove 201 is formed on the side of the inner wall of the tube 101. The first metal tube 202 is inserted into the inner wall of the first annular groove 201. A fixing mechanism is provided between the first metal tube 202 and the tube 101. A support mechanism is provided at the end of the tube 101 away from the first metal tube 202. By inserting the first metal tube 202 into the first annular groove 201 of both tubes 101 at the same time, the two tubes 101 can be spliced ​​together. This allows the first metal tube 202 to support the splice of the two tubes 101, thereby making it less prone to compression deformation at the splice of the two tubes 101 and improving the stability of the spliced ​​tubes 101.

[0022] The fixing mechanism includes a double-sided adhesive layer 301, which is coated on the outer wall of the first metal tube 202. By setting the double-sided adhesive layer 301, the tube body 101 is bonded to the first metal tube 202, thereby making the tube body 101 more stable when spliced ​​and further improving the stability of the tube body 101 when spliced.

[0023] The support mechanism includes a second metal tube 402. A second annular groove 401 is provided on the other side of the inner wall of the tube body 101. The outer wall of the second metal tube 402 is inserted and connected to the inner wall of the second annular groove 401. A reinforcing mechanism is provided on one side of the second metal tube 402. By providing the second metal tube 402, the end position of the tube body 101 is less likely to deform under pressure, thereby improving the stability of the tube body 101 in use.

[0024] The reinforcing mechanism includes a metal ring 502. A third annular groove 501 is provided at one end of the tube body 101. The interior of the third annular groove 501 is connected to the interior of the second annular groove 401. The outer wall of the metal ring 502 is inserted and connected to the inner wall of the third annular groove 501. The metal ring 502 is connected to the second metal tube 402. The outer diameter of the metal ring 502 is larger than the outer diameter of the third annular groove 501. By setting the large outer diameter of the metal ring 502, the force required for the deformation of the metal ring 502 is greater than the force required for the deformation of the second metal tube 402. Therefore, even when the end of the tube body 101 is compressed, the second metal tube 402 is not prone to deformation, further improving the stability of the tube body 101 in use.

[0025] The tube body 101 includes an inner layer 601, a pressure-resistant layer 602, a support layer 603, a protective layer 604, and a wear-resistant layer 605. The protective layer 604 is disposed on the inner wall of the wear-resistant layer 605, the support layer 603 is disposed on the inner wall of the protective layer 604, the pressure-resistant layer 602 is disposed on the inner wall of the support layer 603, and the inner layer 601 is disposed on the inner wall of the pressure-resistant layer 602. The inner layer 601 is made of heat-resistant paper, the pressure-resistant layer 602 is made of paper impregnated with epoxy resin, the support layer 603 is made of composite fiber paper, and the protective layer 604 is made of paper impregnated with phenolic resin. The outer wall of the wear-resistant layer 605 is coated with a wear-resistant coating. The thickness of the inner layer 601 is 0.5 mm to 1.0 mm, and the inner layer 601 provides heat resistance and mechanical strength to the inner wall of the tube body 101. The thickness of the pressure-resistant layer 602 is 1.0 mm to 2.0 mm, and the pressure-resistant layer 602 enhances the heat resistance of the inner wall of the tube body 101. The support layer 603 has a thickness of 1.5 mm to 3.0 mm and is used to provide the overall load-bearing capacity and structural support for the pipe body 101. The protective layer 604 has a thickness of 0.5 mm to 1.5 mm and is used to improve the environmental corrosion resistance of the pipe body 101. The wear-resistant layer 605 has a thickness of 0.2 mm to 0.5 mm and is used to enhance the wear resistance and protective performance of the outer wall of the pipe body 101. The epoxy resin forms a highly network structure through cross-linking reaction, which can provide significant compressive strength and deformation resistance. At the same time, the homogeneity of epoxy resin allows the pipe body 101 to be evenly dispersed under pressure, avoiding material damage caused by stress concentration. The aromatic hydroxyl groups in the phenolic resin have high chemical stability and form a dense protective layer after curing, which can resist the erosion of strong corrosive chemicals.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
