TECHNICAL FIELD

[0001] The utility model relates to paper product field especially relates to a compression resistance textile paper tube. BACKGROUND

[0002] Paper tube is a tubular object processed by paper, most paper tubes are spiral paper tubes and seamless paper tubes, in production and life, paper tubes are usually used for winding spinning, cloth or paper articles, compared with metal pipes, paper tubes are more environmentally friendly, with people's environmental awareness constantly enhancing, the paper tube of environmental protection type is widely popularized, and is used more and more widely, the existing paper tube is often bent and broken due to insufficient strength when being used, and the paper tube is damaged due to the lack of compression resistance structure for supporting.

[0003] For example, the utility model 201921480524X discloses a kind of compression resistance paper tube, including paper tube and outer hoop ring, the outer hoop ring right end cutting is carved with annular groove, the paper tube both ends are inserted with annular groove, the material of paper tube is corrugated paper, the utility model is set by inner oil paper layer and outer oil paper layer, blocks the influence paper tube of water to paper tube, to realize the purpose of compression resistance, but this scheme lacks support in pipe body, and compression resistance effect is limited, affects the article wound on paper tube, affects subsequent normal use. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the utility model provides a compression resistance textile paper tube to solve the above problems.

[0005] In order to solve the above technical problems, the utility model takes the following technical scheme:

[0006] A compression resistance textile paper tube, comprising an inner paper tube and an outer paper tube, a space is provided between the inner paper tube and the outer paper tube, and a plurality of I-shaped support members are arranged in the space in an annular array around the axis;

[0007] A corrugated paper filling layer is provided between the I-shaped support members;

[0008] An outer metal sheet layer is provided on the top of the I-shaped support member, and an inner metal sheet layer is provided on the bottom of the I-shaped support member;

[0009] The outer metal sheet layer is bonded to the outer paper tube;

[0010] The inner metal sheet layer is bonded to the inner paper tube.

[0011] Optionally, the top of the I-shaped support member is an outer convex arc surface that is in close contact with the inner wall of the outer metal sheet layer.

[0012] Optionally, the bottom of the I-shaped support member is a concave arc surface that fits against the outer wall of the inner metal sheet.

[0013] Beneficial effects

[0014] By setting an I-shaped support member between the outer and inner paper tubes, and setting metal sheets inside and outside the I-shaped support member, the outer and inner paper tubes are connected to form a paper tube body, which effectively improves the strength, hardness, toughness and compressive strength of the paper tube body, making the paper tube body less prone to bending and breaking, thereby improving the service life of the paper tube body.

[0023] 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.

[0024] Please see Figure 1 This utility model provides a pressure-resistant textile paper tube, including an inner paper tube 1 and an outer paper tube 6. A space is provided between the inner paper tube 1 and the outer paper tube 6, and a plurality of I-shaped support members 4 are arranged in a circular array around the axis of the space. A corrugated paper filling layer 3 is provided between the I-shaped support members 4. An outer metal sheet layer 5 is provided on the top of the I-shaped support members 4, and an inner metal sheet layer 2 is provided on the bottom of the I-shaped support members 4. The outer metal sheet layer 5 is bonded to the outer paper tube 6.

[0025] The inner metal sheet 2 is bonded to the inner paper tube 1. By setting an I-shaped support member 4 between the outer paper tube 6 and the inner paper tube 1, and setting metal sheets inside and outside the I-shaped support member 4, the outer paper tube 6 and the inner paper tube 1 are connected to form a paper tube body, which effectively improves the strength, hardness, toughness and compressive strength of the paper tube body, making the paper tube body less prone to bending and breaking, thereby improving the service life of the paper tube body.

[0026] To improve fit, the top of the I-shaped support member 4 is a convex arc surface that fits against the inner wall of the outer metal sheet layer 5.

[0027] The bottom of the I-shaped support member 4 is a concave arc surface that fits against the outer wall of the inner metal sheet layer 2.

[0028] Setting inner and outer arcs allows the I-shaped support member 4 to better fit with the metal sheet layer, increasing the stress area and compressive strength.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
