Description

Technical Field

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

[0002] Various types of rollers are used in the production of plastic film, and the venting roller is one of them. The main purpose of the venting roller is to promptly expel the gas between the roller surface and the plastic film to prevent wrinkles from forming on the plastic film under the action of gas, and to flatten the plastic film.

[0003] However, existing exhaust rollers are usually made of metal, which has the following drawbacks in actual use: they are relatively bulky, consume a lot of energy during operation, and their wear resistance and exhaust effect need to be improved. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a carbon fiber exhaust roller that can reduce overall weight, thereby reducing energy consumption, while also improving wear resistance and exhaust performance.

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

[0006] A carbon fiber exhaust roller includes a main roller body and shaft heads disposed at both ends of the main roller body; the main roller body includes a carbon fiber inner tube layer and a wear-resistant coating applied to the outer surface of the carbon fiber inner tube layer, and exhaust grooves are alternately distributed on the outer surface of the carbon fiber inner tube layer.

[0007] Furthermore, the outer surface of the carbon fiber inner tube layer is crisscrossed with several rhomboid-shaped exhaust grooves.

[0008] Furthermore, the shaft head includes an end cover plate and a shaft extending outward from the center of the end cover plate, with the end face of the carbon fiber inner tube layer fixedly connected to the inner surface of the end cover plate.

[0009] Furthermore, the outer surface of the carbon fiber inner tube layer is flush with the circumferential surface of the end cap plate, and the wear-resistant coating extends to the circumferential surface of the end cap plate.

[0010] Furthermore, the thickness of the carbon fiber inner tube layer is 5mm-9mm, and the depth of the exhaust groove is 0.4mm-0.6mm.

[0011] Furthermore, the wear-resistant coating is a ceramic coating.

[0012] Furthermore, the shaft head is a one-piece molded metal shaft head.

[0013] By adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved:

[0014] 1. By designing the main roller body, which includes a carbon fiber inner tube layer and a wear-resistant coating on the outer surface of the carbon fiber inner tube layer, the weight of the entire carbon fiber exhaust roller can be effectively reduced because the density of carbon fiber is 1 / 4 that of steel. This reduces energy consumption during operation, thereby lowering production costs and making it easier to handle the carbon fiber exhaust roller. At the same time, because the specific modulus of carbon fiber is 3 times that of steel, the carbon fiber exhaust roller has stronger rigidity. In addition, the rotational inertia of the entire carbon fiber exhaust roller is low and the critical speed is high during operation.

[0015] 2. By setting a diamond-shaped exhaust groove on the outer surface of the carbon fiber inner tube layer, it is more conducive to gas discharge and can achieve better exhaust effect, thereby playing a better role in flattening the plastic film.

[0016] 3. By spraying a ceramic coating onto the outer surface of the carbon fiber inner tube layer, the wear resistance of the carbon fiber exhaust roller can be further improved, ensuring that it is not easily worn during actual use. Attached Figure Description

[0024] 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.

[0025] Please see the appendix Figures 1 to 3As shown, this utility model provides a preferred embodiment of a carbon fiber exhaust roller 100. The carbon fiber exhaust 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 convey 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 exhaust roller 100. The main roller body 1 includes a carbon fiber inner tube layer 11 and a wear-resistant coating 12 coated on the outer surface of the carbon fiber inner tube layer 11. Exhaust grooves 13 are staggered on the outer surface of the carbon fiber inner tube layer 11 to achieve the exhaust effect.

[0026] This invention designs the main roller body 1 to include a carbon fiber inner tube layer 11 and a wear-resistant coating 12 applied to the outer surface of the carbon fiber inner tube layer 11. Since the density of carbon fiber is 1 / 4 that of steel, the weight of the entire carbon fiber exhaust roller 100 can be effectively reduced. This reduces energy consumption during operation, thereby lowering production costs, and also makes it easier to handle the carbon fiber exhaust roller 100. At the same time, since the specific modulus of carbon fiber is 3 times that of steel, the carbon fiber exhaust roller 100 has stronger rigidity. In addition, the moment of inertia of the entire carbon fiber exhaust roller 100 is low and the critical speed is high during operation.

[0027] In the preferred embodiment of this utility model, please refer to the following: Figure 3 As shown, the outer surface of the carbon fiber inner tube layer 11 has a plurality of diamond-shaped exhaust grooves 13 interwoven. By setting the diamond-shaped exhaust grooves 13 on the outer surface of the carbon fiber inner tube layer 11, it is more conducive to gas exhaust and can achieve better exhaust effect, thereby playing a better role in flattening the plastic film.

[0028] In a preferred embodiment of this invention, the shaft head 2 includes an end cover plate 21 and a shaft body 22 extending outward from the center of the end cover plate 21. The end face of the carbon fiber inner tube layer 11 is fixedly connected to the inner surface of the end cover plate 21. The shaft body 22 is used to achieve a rotatable connection with the support structure. In specific implementations of this invention, the end face of the carbon fiber inner tube layer 11 and the inner surface of the end cover plate 21 can be fixed together by adhesive bonding, or by using screws and adhesive to fix the end face of the carbon fiber inner tube layer 11 to the inner surface of the end cover plate 21.

[0029] In a preferred embodiment of the present invention, the outer surface of the carbon fiber inner tube layer 11 is flush with the circumferential surface of the end cover plate 21, and the wear-resistant coating 12 extends to the circumferential surface of the end cover plate 21. This makes the entire circumferential surface of the carbon fiber exhaust roller 100 wear-resistant, and at the same time makes the external structure of the entire carbon fiber exhaust roller 100 simpler and more beautiful.

[0030] In one specific embodiment of this utility model, the thickness of the carbon fiber inner tube layer 11 is 5mm-9mm, and the depth of the exhaust groove 13 is 0.4mm-0.6mm. Of course, the above is only one specific embodiment of this utility model, but it is not limited thereto. In specific implementations, the thickness of the carbon fiber inner tube layer 11 and the depth of the exhaust groove 13 can be adjusted according to actual needs.

[0031] In one specific embodiment of this utility model, the wear-resistant coating 12 is a ceramic coating. By spraying a ceramic coating onto the outer surface of the carbon fiber inner tube layer 11, the wear resistance of the carbon fiber exhaust roller 100 can be further improved, ensuring that it is not easily worn during actual use. Of course, the above is only one specific embodiment of this utility model, but this utility model is not limited to this. In specific implementations, wear-resistant coatings of other materials can also be used according to actual needs.

[0032] As a 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] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
