Description

Technical Field

[0001] The utility model relates to the technical field of industrial paper tubes, in particular to a compression-resistant industrial paper tube. Background Art

[0002] An industrial paper tube is a tubular object processed from paper. Most paper tubes are spiral paper tubes and seamless paper tubes, which are applied in multiple industries. In the textile industry, they are widely used for winding and transporting yarns, fabrics, etc. In the food industry, they are often used for packaging and transporting various foods, such as potato chips, candies, nuts, etc. In the chemical industry, they are used for packaging various chemical substances. In the pharmaceutical industry, they are used for packaging various solid and liquid medicines, such as tablets, capsules, potions, etc.

[0003] However, in the prior art, due to the limited thickness of industrial paper tubes and the fact that when they are stored or transported, most of them are placed in a stacked manner, and the supporting strength of existing industrial paper tubes is limited, resulting in poor compression resistance. Therefore, when the items they package are heavy, it is extremely easy to cause the paper tubes to deform, thus easily damaging the internal packages, greatly reducing the protection effect of industrial paper tubes. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the prior art that the existing industrial paper tubes have limited supporting strength and poor compression resistance, and to propose a compression-resistant industrial paper tube.

The anti-corrosion reinforcing inner layer is adhesively fixed inside the cardboard inner core, the fireproof and heat-insulating reinforcing outer layer is sleeved outside the cardboard inner core, and a number of reinforcing cardboard pieces are equidistantly fixed between the inner wall of the fireproof and heat-insulating reinforcing outer layer and the outer surface of the cardboard inner core. The inner wall of the anti-corrosion reinforcing inner layer and the outer surface of the fireproof and heat-insulating reinforcing outer layer are both coated with a waterproof coating, and an anti-scratch film is coated outside each waterproof coating.

[0006] Preferably, a number of reinforcing inner rods are equidistantly fixed inside the paper tube body. The middle parts of every two reinforcing inner rods are cross-fixed to form an "X" shape, and the number of reinforcing inner rods inside the paper tube body is an even number.

[0007] Preferably, a number of reinforcing support rods are equidistantly embedded and fixed inside the cardboard inner core, and the length of the reinforcing support rods is equal to the length of the cardboard inner core. The thickness of the reinforcing support rods is less than the thickness of the cardboard inner core.

[0008] Preferably, cardboard cores are fixed to the front and rear edges of the outer layer of fireproof and heat-insulating reinforcement and the inner edges of the front and rear ends of the anti-corrosion reinforcement layer, and another waterproof coating is applied to the outside of the cardboard cores, and an anti-scratch film is applied to the outside of the other waterproof coating.

[0009] Preferably, every two adjacent reinforcing cardboard pieces are triangular in shape, and the length of each reinforcing cardboard piece is equal to the length of the cardboard core. The inner and outer sides of each reinforcing cardboard piece are respectively fixed to the outer surface of the cardboard core and the inner wall of the fireproof and heat-insulating reinforcement outer layer.

[0010] Preferably, the thicknesses of the inner and outer waterproof coatings are both equal to the thickness of the anti-scratch film, and the other waterproof coating and the anti-scratch film at the front and rear are respectively merged and communicated with the waterproof coatings and the anti-scratch films on the inner and outer sides.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0020] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification. Embodiment 1

[0021] As Figures 1-4 shown, the present utility model provides a compression-resistant industrial paper tube, including a paper tube body 1. The paper tube body 1 includes a cardboard inner core 11, a fireproof and heat-insulating reinforced outer layer 13, an anti-corrosion reinforced inner layer 14, reinforced cardboard pieces 15, a waterproof coating 16 and an anti-scratch film 17. An anti-corrosion reinforced inner layer 14 is adhesively fixed inside the cardboard inner core 11. A fireproof and heat-insulating reinforced outer layer 13 is sleeved outside the cardboard inner core 11. A plurality of reinforced cardboard pieces 15 are equidistantly fixed between the inner wall of the fireproof and heat-insulating reinforced outer layer 13 and the outer surface of the cardboard inner core 11. Every two adjacent reinforced cardboard pieces 15 are triangular. The length of each reinforced cardboard piece 15 is equal to the length of the cardboard inner core 11. The inner and outer sides of each reinforced cardboard piece 15 are respectively fixed on the outer surface of the cardboard inner core 11 and the inner wall of the fireproof and heat-insulating reinforced outer layer 13. The inner wall of the anti-corrosion reinforced inner layer 14 and the outer surface of the fireproof and heat-insulating reinforced outer layer 13 are both coated with a waterproof coating 16. An anti-scratch film 17 is coated outside each waterproof coating 16.

[0022] The following specifically describes the specific settings and functions of this embodiment: The front and rear edges of the fireproof and heat-insulating reinforced outer layer 13 and the inner edges of the front and rear ends of the anti-corrosion reinforced inner layer 14 are both fixed with the cardboard inner core 11. Another waterproof coating 16 is coated outside the cardboard inner core 11, and an anti-scratch film 17 is coated outside another waterproof coating 16 to protect the front and rear ends of the paper tube body 1, thereby preventing water stains from seeping into the inside of the paper tube body 1 and ensuring the waterproof performance inside the paper tube body 1. A plurality of reinforcing struts 12 are equidistantly embedded and fixed inside the cardboard inner core 11. The length of the reinforcing struts 12 is equal to the length of the cardboard inner core 11. The thickness of the reinforcing struts 12 is smaller than the thickness of the cardboard inner core 11. The vertical supporting performance of the paper tube body 1 is further enhanced through the reinforcing struts 12, thereby improving the compression resistance of the paper tube body 1. The thicknesses of the inner and outer waterproof coatings 16 are both equal to the thickness of the anti-scratch film 17. Another waterproof coating 16 and anti-scratch film 17 at the front and rear are respectively converged and communicated with the waterproof coatings 16 and anti-scratch films 17 on the inner and outer sides to ensure the overall waterproof and anti-scratch effects of the waterproof coating 16 and the anti-scratch film 17. Embodiment 2

[0023] As shown Figures 1-4 in the figure, several reinforcing inner rods 2 are fixedly arranged at equal intervals inside the paper tube body 1, and the middle parts of every two reinforcing inner rods 2 are cross-fixed to form an "X" shape, and the number of the reinforcing inner rods 2 inside the paper tube body 1 is an even number.

[0024] The effect achieved by the whole embodiment is that the inner part of the paper tube body 1 is further strengthened and supported by the reinforcing inner rods 2, and the number of the reinforcing inner rods 2 inside the paper tube body 1 can be adjusted according to the required supporting strength and compressive strength of the paper tube body 1. The greater the required supporting strength, the more the number of the reinforcing inner rods 2 inside the paper tube body 1, and the smaller the required supporting strength, the fewer the number of the reinforcing inner rods 2 inside the paper tube body 1.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
