Description

Technical Field

[0001] This utility model relates to the field of air flotation roller technology, specifically a carbon fiber air flotation roller. Background Technology

[0002] Air-bearing rollers are industrial devices that utilize air-bearing technology to achieve non-contact conveying. They form a micron-sized air film between the roller surface and the product using compressed air, significantly reducing friction and pressure deviation. They are currently widely used in plastic film, printing, papermaking, and electronic component manufacturing.

[0003] Existing air flotation rollers are usually made of metal (generally steel), which are bulky and difficult to handle, and generate a lot of energy during production, which is not conducive to reducing production costs. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this utility model provides a carbon fiber air flotation roller, which can not only reduce the energy consumption generated in the production process, thereby reducing the production cost, but also make the handling more convenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A carbon fiber air-bearing roller includes a main roller body and shaft heads located at both ends of the main roller body. The shaft heads are provided with air inlets communicating with the interior of the main roller body, and the outer surface of the main roller body is provided with a plurality of exhaust holes communicating with the interior of the main roller body. The main roller body includes a carbon fiber inner tube and an outer skin layer sleeved on the outside of the carbon fiber inner tube. The exhaust holes extend from the outer surface of the outer skin layer to the inner wall of the carbon fiber inner tube.

[0007] Furthermore, the shaft head includes an end cap plate and a shaft extending outward from the center of the end cap plate. The end cap plate is connected to the end of the carbon fiber inner tube and the outer skin layer. The air inlet extends from the free end face of the shaft body to the inner surface of the end cap plate.

[0008] Furthermore, the length of the outer skin layer along the axial direction is greater than the length of the carbon fiber inner tube, and the end face of the carbon fiber inner tube is connected to the inner surface of the end cap plate; the inner wall of the end of the outer skin layer is connected to the circumferential surface of the end cap plate.

[0009] Furthermore, the end face of the outer skin layer is flush with the outer surface of the end cap plate.

[0010] Furthermore, the shaft includes a first shaft segment connected to the middle of the end cover plate and a second shaft segment connected to the first shaft segment, wherein the outer diameter of the first shaft segment is larger than the outer diameter of the second shaft segment.

[0011] Furthermore, the carbon fiber inner tube and outer skin have several rings of exhaust holes evenly distributed in the middle.

[0012] Furthermore, the outer skin layer and the carbon fiber inner tube are fixed together by adhesive bonding.

[0013] Furthermore, the shaft head is a one-piece molded metal shaft head.

[0014] Furthermore, the outer skin layer is a stainless steel outer skin layer.

[0015] By adopting the above-mentioned technical solution of this utility model, at least the following beneficial effects are achieved: by designing the main roller body to include a carbon fiber inner tube and an outer skin layer sleeved on the outside of the carbon fiber inner tube, on the one hand, since the density of carbon fiber is 1 / 4 that of steel, the weight of the entire carbon fiber air bearing roller can be effectively reduced. This not only reduces the energy consumption generated during the production process, thereby reducing production costs, but also makes it easier to handle the carbon fiber air bearing roller; on the other hand, since the specific modulus of carbon fiber is 3 times that of steel, the carbon fiber air bearing roller can have stronger rigidity.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Please see the appendix Figures 1 to 2As shown, this utility model provides a preferred embodiment of a carbon fiber air-bearing roller 100. The carbon fiber air-bearing roller 100 includes a main roller body 1 and shaft heads 2 disposed at both ends of the main roller body 1. The main roller body 1 is used to transport plastic film, and the shaft heads 2 are used to rotatably connect with a support structure (not shown) to meet the support requirements of the entire carbon fiber air-bearing roller 100. The shaft heads 2 are provided with air inlets 21 that communicate with the interior of the main roller body 1, so as to transport gas to the interior of the main roller body 1 through the air inlets 21. The outer surface of the main roller body 1 is provided with a plurality of holes that communicate with the interior of the main roller body 1. The exhaust port 11 is connected to the main roller body 1 and is used to discharge the gas inside the main roller body 1. Since the plastic film passes through the outer surface of the main roller body 1, a micron-sized air film can be formed between the outer surface of the main roller body 1 and the plastic film during the actual operation, thereby reducing friction and pressure deviation. The main roller body 1 includes a carbon fiber inner tube 12 and an outer skin layer 13 sleeved on the outside of the carbon fiber inner tube 12. The exhaust port 11 penetrates from the outer surface of the outer skin layer 13 to the inner wall of the carbon fiber inner tube 12, so that the gas can be discharged from the outer surface of the outer skin layer 13.

[0024] This invention designs the main roller body 1 to include a carbon fiber inner tube 12 and an outer skin layer 13 sleeved on the outside of the carbon fiber inner tube 12. On the one hand, since the density of carbon fiber is 1 / 4 that of steel, the weight of the entire carbon fiber air bearing roller 100 can be effectively reduced. This reduces energy consumption during production, thereby reducing production costs, and also makes it easier to handle the carbon fiber air bearing roller 100. On the other hand, since the specific modulus of carbon fiber is 3 times that of steel, the carbon fiber air bearing roller 100 can have stronger rigidity.

[0025] In a preferred embodiment of this invention, the shaft head 2 includes an end cover plate 22 and a shaft body 23 extending outward from the middle of the end cover plate 22. The end cover plate 22 is connected to the ends of the carbon fiber inner tube 12 and the outer skin layer 13. The air inlet 21 extends from the free end face of the shaft body 23 to the inner surface of the end cover plate 22. The end cover plate 22 is used to seal both ends of the main roller body 1, and the shaft body 23 is used for rotatable connection with the support structure. In specific implementations of this invention, air inlets 21 can be provided on both ends of the shaft head 2 of the main roller body 1, or only on one of the shaft heads 2; the choice can be made according to actual needs.

[0026] Furthermore, in order to better connect the end cover plate 22 with the main roller body 1 and ensure a sealing effect, the length of the outer skin layer 13 along the axial direction is greater than the length of the carbon fiber inner tube 12, the end face of the carbon fiber inner tube 12 is connected to the inner surface of the end cover plate 22, and the inner wall of the end of the outer skin layer 13 is connected to the circumferential surface of the end cover plate 22.

[0027] In a specific implementation of this invention, the outer skin layer 13 and the carbon fiber inner tube 12 are fixed together by adhesive bonding; the inner wall of the end of the outer skin layer 13 is also fixed together with the circumferential surface of the end cover plate 22 by adhesive bonding, and the end face of the outer skin layer 13 and the outer surface of the end cover plate 22 can be fixed together by welding to ensure that the end cover plate 22 can be reliably connected to the end of the main roller body 1 and to ensure a sealing effect.

[0028] As a specific embodiment of this utility model, the end face of the outer skin layer 13 is flush with the outer surface of the end cover plate 22, which makes the external structure of the entire carbon fiber air flotation roller 100 simpler and more beautiful.

[0029] In one specific embodiment of the present invention, the shaft 23 includes a first shaft segment 231 connected to the middle part of the end cover plate 22 and a second shaft segment 232 connected to the first shaft segment 231, wherein the outer diameter of the first shaft segment 231 is larger than the outer diameter of the second shaft segment 232.

[0030] This utility model designs the shaft body 23 to include a first shaft segment 231 and a second shaft segment 232, so that in the specific use process, on the one hand, the first shaft segment 231 can be used to achieve a rotatable connection with the support structure, and on the other hand, the second shaft segment 232 can be used to connect with an external air pipe (not shown) to realize the delivery of gas into the main roller body 1.

[0031] In a preferred embodiment of this invention, to achieve a better air flotation effect, several rings of exhaust holes 11 are evenly distributed in the middle of the carbon fiber inner tube 12 and the outer skin layer 13. As a specific implementation of this invention, the spacing between two adjacent exhaust holes 11 on the same ring is equal, and the exhaust holes 11 on each ring are aligned. Of course, the above is only one specific implementation of this invention, but this invention is not limited to this; in specific implementations, the position, spacing, and arrangement of each exhaust hole 11 can be adjusted according to actual needs.

[0032] In one specific embodiment of this utility model, in order to ensure the overall strength of the shaft head 2, the shaft head 2 is a one-piece molded metal shaft head.

[0033] In one specific embodiment of this utility model, the outer skin layer 13 is a stainless steel outer skin layer, which enables the outer skin layer 13 to better protect the carbon fiber inner tube 12.
