[0002] Paper tube refers to a tubular object made of paper. Paper tube is widely used in packaging paper products, textiles and other fields. Most of the existing paper tubes are spiral paper tubes and seamless paper tubes. In the use scenario that needs to withstand a certain pressure, the outer wall strength of the tube is not enough, and it will bend or collapse, and it can not provide better support for the product. To solve this problem, we propose a hollow pressure-resistant paper tube. Utility Model Content

[0006] Preferably, a support frame is fixedly connected to the inner wall of the first paper tube layer, and the support frame is an integrated structure.

[0007] Preferably, the tube body assembly further comprises a first waterproof layer, the first waterproof layer is arranged inside the first paper tube layer, and a polyethylene film is provided on the inner wall of the first waterproof layer.

[0008] Preferably, the end of the support frame passes through the first waterproof layer.

[0009] Preferably, the reinforcing rib layer is arranged in a cross-shaped structure, and a support ring is provided inside the reinforcing rib layer, and the support ring is evenly distributed in the tube body assembly.

[0010] Preferably, the tube body assembly further comprises a second waterproof layer, the second waterproof layer is arranged on the outer wall of the second paper tube layer, and the outer wall of the second waterproof layer is provided with a polyethylene film.

[0011] Preferably, the pipe body assembly further comprises a wear-resistant layer, the wear-resistant layer is arranged on the outer wall of the second waterproof layer, and the wear-resistant layer is a polymer wear-resistant coating.

[0013] Compared with the prior art, the utility model provides a hollow pressure-resistant paper tube, which has the following beneficial effects:

[0014] The support frame penetrates the first waterproof layer and is fixedly connected to the first paper tube layer. The support frame is an integrated structure of multiple connecting rods, which provides great support for the paper tube. The polyethylene film on the inner wall of the first waterproof layer can effectively prevent the intrusion of water vapor inside the tube body assembly. When the internal paper tube is damp, the strength of the paper tube will be reduced. The metal mesh layer and the reinforcing rib layer improve the internal structural strength so that the paper tube can withstand greater pressure. A support ring is provided inside the reinforcing rib layer to provide support for the paper tube so that the paper tube is not easy to bend. A polyethylene film is provided on the outer wall of the second waterproof layer to effectively block external water vapor. The wear-resistant layer provided on the outermost layer is made of polytetrafluoroethylene material, which has good wear resistance, reduces the wear of the paper tube, and increases its service life. Waterproof covers are provided at both ends of the paper tube to improve the waterproof performance of the exposed end faces of the paper tube. BRIEF DESCRIPTION OF THE DRAWINGS
