Description

[Technical Field]

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

[0002] In composite wheel cutter head equipment, the rollers are the core transmission and support components, and their performance directly affects the equipment's operating efficiency, machining accuracy, and product quality. Traditional rollers are generally made of metal materials (such as stainless steel, carbon steel, or aluminum alloy). However, existing metal rollers have the following significant drawbacks:

[0003] 1. Excessive weight increases the overall load and energy consumption of the equipment.

[0004] 2. Difficult to process and prone to burrs. In order to meet the needs of ventilation, heat dissipation and weight reduction, it is often necessary to drill holes in the tube wall. Burrs, curling or deformation are easily generated during the drilling process. These defects cause scratch damage and other problems when the roller is used for material in-rolling.

[0005] 3. Dense perforation on metal rollers to achieve good ventilation will inevitably significantly weaken the structural strength and rigidity of the pipe, especially in the central area where it is subjected to large bending moments. Existing technology lacks a design scheme that effectively balances high strength and good ventilation requirements.

[0006] In view of this, this case involves in-depth research into the aforementioned issues, which led to the formation of this case. [Utility Model Content]

[0007] The present invention aims to solve the above-mentioned technical problems of existing metal rollers by providing a carbon fiber roller that achieves significant weight reduction and high specific strength while optimizing the ventilation hole layout to balance ventilation efficiency and structural strength.

[0008] This utility model is implemented as follows: a carbon fiber roller includes a tube body, an inner flange, and an outer flange. The tube body includes an inner end and an outer end, with the inner flange installed at the inner end and the outer flange installed at the outer end. The tube body is a carbon fiber tube body, and the tube wall of the carbon fiber tube body is provided with perforated parts.

[0009] Furthermore, the outer surface of the carbon fiber tube is coated with an anti-slip and wear-resistant alloy layer.

[0010] Furthermore, the perforated part includes a first perforation group, a second perforation group, and a third perforation group arranged sequentially along the axial direction; the first perforation group includes multiple sets of first perforation rings distributed along the axial direction, the second perforation group includes multiple sets of second perforation rings distributed along the axial direction, and the third perforation group includes multiple sets of third perforation rings distributed along the axial direction; the gap between adjacent first perforation rings and the gap between adjacent third perforation rings are both smaller than the gap between adjacent second perforation rings.

[0011] Furthermore, the inner flange includes an inner flange inner ring and an outer flange coaxially arranged. The inner wall of the outer flange forms an inner limiting step, and the outer wall of the inner flange forms a first inner convex ring for abutting against the inner limiting step. The inner flange inner ring is locked to the outer flange by a first bolt. The inner limiting step forms a first internal threaded hole for installing the first bolt, and the first inner convex ring forms a second internal threaded hole for installing the first bolt. The outer flange includes an outer flange inner ring and an outer flange coaxially arranged. The inner wall of the outer flange forms an outer limiting step, and the outer wall of the outer flange inner ring forms a first outer convex ring for abutting against the outer limiting step. The outer flange inner ring is locked to the outer flange outer ring by a second bolt. The outer limiting step forms a first external threaded hole for installing the second bolt, and the first external convex ring forms a second external threaded hole for installing the second bolt.

[0012] Furthermore, the outer wall of the inner flange outer ring forms a second inner convex ring for abutting the inner end, the inner flange outer ring forms a third internal threaded hole, the inner end forms a fourth internal threaded hole, and the inner flange outer ring is locked to the inner end by a third bolt; the outer wall of the outer flange outer ring forms a second outer convex ring for abutting the outer end, the outer side plate forms a third external threaded hole, the outer end forms a fourth external threaded hole, and the outer flange outer ring is locked to the outer end by a fourth bolt.

[0013] Furthermore, the outer ring of the inner flange forms multiple inner through holes, and the outer ring of the inner flange is provided with an inner cover plate that covers the inner through holes; the outer ring of the outer flange forms multiple outer through holes, and the outer ring of the outer flange is provided with an outer cover plate that covers the outer through holes.

[0014] Furthermore, the inner ring of the inner flange is an aluminum alloy inner flange inner ring; the outer ring of the inner flange is an alloy steel inner flange outer ring; the inner ring of the outer flange is an alloy steel outer flange inner ring; and the outer ring of the outer flange is an aluminum alloy outer flange outer ring.

[0015] Furthermore, the inner cover is a PC inner cover, and the outer cover is a PC outer cover.

[0016] The advantages of this utility model are:

[0017] 1. The carbon fiber roller of this utility model uses a carbon fiber tube body instead of a traditional metal tube body, which significantly reduces the overall weight of the roller. The carbon fiber material has a high specific strength (strength / density ratio), which can withstand a large working load while reducing weight. By setting perforations in the tube wall of the carbon fiber body, ventilation paths are provided for the roller, which helps to dissipate heat or remove dust.

[0018] 2. The axially distributed perforated ring group design provides a regular perforation pattern, which helps maintain the overall stiffness and stability of the carbon fiber tube and avoids stress concentration or local deformation caused by irregular perforation. By setting three groups of perforated ring groups with different gaps (the first and third groups have small gaps, and the second group has a large gap), more dense holes are provided in areas that require better ventilation (such as the first and third perforated ring groups near the ends), while more carbon fiber tube material is retained in the middle area that bears a large bending moment (the second perforated ring group) to maintain high strength. This design achieves the best balance between ventilation requirements and structural strength. [Attached Image Description]

Detailed Implementation Methods

[0024] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figures 1 to 3As shown, this utility model provides a carbon fiber roller, including a tube body 1, an inner flange 2, and an outer flange 3. The tube body 1 includes an inner end and an outer end, with the inner flange 2 installed at the inner end and the outer flange 3 installed at the outer end. The tube body 1 is a carbon fiber tube body 1, and the tube wall of the carbon fiber tube body 1 has perforated portions 4. Using a carbon fiber tube body 1 instead of a traditional metal tube body 1 significantly reduces the overall weight of the roller. Carbon fiber material has a high specific strength (strength / density ratio), which allows it to withstand a large workload while reducing weight. By providing perforated portions 4 on the tube wall of the carbon fiber tube body 1, a ventilation path is provided for the roller, which helps to dissipate heat or remove dust.

[0026] In this invention, the outer surface of the carbon fiber tube 1 is coated with an anti-slip and wear-resistant alloy layer. This layer isolates the carbon fiber tube 1 from direct damage caused by external environmental factors (such as oxidation and friction). The anti-slip and wear-resistant alloy layer is a nickel-chromium-aluminum alloy layer, which is itself heat-resistant and oxidation-resistant, making it suitable for working environments that may generate high temperatures. The anti-slip and wear-resistant alloy layer is applied to the outer surface of the carbon fiber tube 1 using a high-temperature plasma spraying process, ensuring a firm deposition of a high-melting-point alloy coating on the carbon fiber tube 1 and overcoming the problems of carbon fiber's poor heat resistance and the tendency for spraying to fail.

[0027] In this invention, the perforated section 4 includes a first perforation group 41, a second perforation group 42, and a third perforation group 43 arranged sequentially along the axial direction. The first perforation group 41 includes multiple sets of first perforated ring groups 411 distributed along the axial direction, the second perforation group 42 includes multiple sets of second perforated ring groups 421 distributed along the axial direction, and the third perforation group 43 includes multiple sets of third perforated ring groups 431 distributed along the axial direction. The gaps between adjacent first perforated ring groups 411 and adjacent third perforated ring groups 431 are smaller than the gaps between adjacent second perforated ring groups 421. Each perforated ring group consists of multiple equally spaced circumferentially distributed perforations, ensuring uniform ventilation along the circumferential direction. The axially distributed perforated ring group design provides a regular perforation pattern, which helps maintain the overall stiffness and stability of the carbon fiber tube 1 and avoids stress concentration or local deformation caused by irregular perforation. By setting three sets of perforated rings with different gaps (the first and third sets have small gaps, and the second set has large gaps), denser holes are provided in areas requiring better ventilation (such as the first perforated group 41 and the third perforated group 43 near the end), while more carbon fiber tube material is retained in the middle area (the second perforated group 42) to maintain high strength, achieving the best balance between ventilation requirements and structural strength.

[0028] In this utility model, the inner flange 2 includes an inner flange inner ring 21 and an inner flange outer ring 22 coaxially arranged. The inner wall of the inner flange outer ring 22 forms an inner limiting step 221, and the outer wall of the inner flange inner ring 21 forms a first inner convex ring 211 for abutting against the inner limiting step 221. The inner flange inner ring 21 is locked to the inner flange outer ring 22 by a first bolt 23. The inner limiting step 221 forms a first internal threaded hole for installing the first bolt 23, and the first inner convex ring 211 forms a second internal threaded hole for installing the first bolt 23. The outer flange 3 includes an inner ring 31 and an outer ring 32 coaxially arranged. The inner wall of the outer ring 32 forms an outer limiting step 321, and the outer wall of the inner ring 31 forms a first outer convex ring 311 for abutting against the outer limiting step 321. The inner ring 31 is locked to the outer ring 32 by a second bolt 33. The outer limiting step 321 forms a first external threaded hole for installing the second bolt 33, and the first outer convex ring 311 forms a second external threaded hole for installing the second bolt 33. The inner flange 2 and the outer flange 3 adopt a split structure of inner ring + outer ring. The cooperation of the limiting step and the convex ring achieves precise axial positioning of the side plate assembly (preventing misalignment of the inner and outer rings). The coaxial inner and outer rings help ensure the coaxiality of the entire side plate assembly, thereby ensuring the overall rotational accuracy of the roller. The split structure is easy to manufacture and facilitates later disassembly and maintenance. Bolts are used to lock the inner and outer rings together to form a rigid side plate assembly structure.

[0029] In this invention, to achieve stable connection between the carbon fiber tube 1 and the side plate assembly, the outer wall of the inner flange outer ring 22 forms a second inner convex ring 222 for abutting the inner end, the inner flange outer ring 22 has a third internal threaded hole, and the inner end has a fourth internal threaded hole. The inner flange outer ring 22 is locked to the inner end by a third bolt 24. The outer wall of the outer flange outer ring 32 forms a second outer convex ring 322 for abutting the outer end, the outer side plate has a third external threaded hole, and the outer end has a fourth external threaded hole. The outer flange outer ring 32 is locked to the outer end by a fourth bolt 34. The use of convex ring positioning and bolt locking facilitates installation and completely avoids welding, which is essential for the non-weldable carbon fiber tube 1 and eliminates the heat-affected zone, deformation, and residual stress problems caused by welding.

[0030] In this invention, the inner flange outer ring 22 forms multiple inner through holes 223, and the inner flange outer ring 22 is provided with an inner cover plate 224 covering the inner through holes 223; the outer flange outer ring 32 forms multiple outer through holes 323, and the outer flange outer ring 32 is provided with an outer cover plate 324 covering the outer through holes 323. Providing through holes on the outer ring can effectively reduce the overall weight and further optimize the lightweight design of the roller. The inner through holes 223 and outer through holes 323 can serve as channels for threading wires, installing sensors or other accessories, or facilitating later maintenance. The inner cover plate 224 and outer cover plate 324 are used to seal these through holes, preventing foreign objects from entering or maintaining a clean appearance.

[0031] In this invention, the inner flange inner ring 21 is a lightweight, high-strength aluminum alloy inner flange inner ring 21; the inner flange outer ring 22 is a high-strength, wear-resistant alloy steel inner flange outer ring 22; the outer flange inner ring 31 is a high-strength, wear-resistant alloy steel outer flange inner ring 31; and the outer flange outer ring 32 is a lightweight, high-strength aluminum alloy outer flange outer ring 32. The lightweight, high-strength aluminum alloy is 6063-T6 aluminum alloy; the high-strength, wear-resistant alloy steel is 40Cr alloy. Appropriate materials are selected based on the different loads borne by different components in the roller (e.g., the inner flange outer ring 22 and outer flange inner ring 31 may bear greater assembly preload or working load). Lightweight, high-strength aluminum alloy is used for the inner ring 21 of the inner flange and the outer ring 32 of the outer flange (contact surfaces or areas requiring lightweighting), providing good lightweighting, corrosion resistance, and a certain level of strength; high-strength, wear-resistant alloy steel is used for the outer ring 22 of the inner flange and the inner ring 31 of the outer flange (critical load-bearing areas or areas requiring wear resistance), providing higher strength, hardness, and wear resistance; this combination meets functional requirements (lightweight, load-bearing, and wear-resistant) while being lighter and more economical than using all high-specification alloy steel.

[0032] In this invention, the inner cover plate 224 is a PC inner cover plate 224, and the outer cover plate 324 is a PC outer cover plate 324. The PC cover plate is lighter than the metal cover plate and is transparent, making it easy to observe the inside of the through hole. If inspection is required, the cover plate does not need to be removed.

[0033] In this invention, the inner wall of the carbon fiber tube 1 is a smooth surface. The smooth inner wall surface significantly reduces the frictional resistance generated when materials (such as films, paper, and fabrics) are wound or run on the inner surface of the roller, and also eliminates the risk of damage to the rolled material caused by burrs or rough points, thereby improving product quality.

[0034] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
