Abstract
Description
Technical Field
[0001] This application relates to the field of carbon fiber roller technology, specifically carbon fiber micro-carving roller. Background Technology
[0002] A carbon fiber micro-carved roller is a roller component made of carbon fiber material with a surface micro-carving process. It generally consists of a carbon fiber roller body, a metal shaft head, and micro-carved patterns or structures on the surface. The carbon fiber roller body provides basic properties such as high strength and lightweight. The metal shaft head is used to connect the drive device or other components to realize the roller's rotation function. The micro-carved parts on the surface are designed and processed according to specific application requirements, such as having specific textures, patterns, and micropores to meet the needs of different processes, such as printing, coating, and embossing.
[0003] Many existing carbon fiber micro-carving rollers feature a hollow internal design with a central shaft secured at both ends by bushings. During coating or embossing, the roller presses against the object and rotates to imprint the texture onto it. However, due to the lack of support in the central area, while carbon fiber boasts high strength and rigidity, the roller's buckling resistance still depends on its structural integrity. This lack of support in the central area can lead to localized stress concentration that exceeds the material's allowable bending strength, especially under prolonged and repeated stress, potentially causing fatigue deformation and affecting the roller's lifespan.
[0004] Therefore, it is necessary to provide carbon fiber micro-carving rollers to solve the above problems.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0033] like Figure 1-2 As shown, this application provides a carbon fiber micro-carving roller, including a carbon fiber roller body 1, which has a hollow design and is made of high-performance carbon fiber composite material. This material uses carbon fiber as reinforcement and epoxy resin as matrix, and is processed by winding molding process. It not only has extremely high strength and rigidity, but also features light weight, corrosion resistance, and low coefficient of thermal expansion.
[0034] The outer wall of the carbon fiber roller body 1 is covered with precise micro-engraved patterns 6, which are processed by laser engraving technology. The depth, spacing, and shape of the patterns can be customized according to specific processing requirements. For example, in the film embossing process, the micro-engraved patterns 6 can be specific patterns or textures that can press clear and uniform patterns onto the film surface.
[0035] A central shaft 2 is installed inside the carbon fiber roller body 1. The central shaft 2 is made of high-strength alloy steel and has been heat-treated to have good toughness and fatigue resistance, enabling it to withstand torque and radial force during roller operation. Both ends of the central shaft 2 are fitted with bushings 5, which are made of wear-resistant ductile iron. These bushings are fixed to the central shaft 2 with high-strength bolts, and the connection points are coated with thread-locking adhesive to prevent loosening during long-term operation.
[0036] Two bushings 5 are tightly fitted inside both ends of the carbon fiber roller body 1, and the bushings 5 and the carbon fiber roller body 1 are interference-fitted. The interference amount is precisely calculated to ensure the firmness of the connection between the two and to avoid internal damage to the carbon fiber roller body 1 due to excessive interference. This connection method can effectively transmit torque and ensure that the carbon fiber roller body 1 and the central shaft 2 operate synchronously.
[0037] Both ends of the central shaft 2 are fixed with shaft heads 4. The shaft heads 4 are made by an integrated forging process and are welded to the central shaft 2 before precision machining to ensure the coaxiality of the shaft heads 4 and the central shaft 2. The ends of the shaft heads 4 are provided with standard connection interfaces, which can be connected to external power equipment such as motors and reducers to facilitate the driving and speed adjustment of the roller.
[0038] like Figure 3-4As shown, in order to enhance the structural stability of the carbon fiber roller body 1, a reinforcing component 3 is provided on the central shaft 2 for its hollow internal part. The reinforcing component 3 includes a first sliding sleeve 31 and a second sliding sleeve 38 that are slidably sleeved on the central shaft 2. Both the first sliding sleeve 31 and the second sliding sleeve 38 are made of lightweight aluminum alloy material and have undergone anodizing treatment, which has good wear resistance and oxidation resistance.
[0039] The first limiting plate 34 and the second limiting plate 311 are fixedly installed on both sides of the middle part of the central shaft 2. These two limiting plates are made of steel plates and are welded and fixed to the central shaft 2. They are used to limit the position of the first sliding sleeve 31 and the second sliding sleeve 38 to ensure the accuracy of the installation position of the first sliding sleeve 31 and the second sliding sleeve 38.
[0040] Multiple first support ribs 32 are uniformly fixedly installed on the outer wall of the first sliding sleeve 31. The first support ribs 32 are made of high-strength alloy steel strips and are connected to the first sliding sleeve 31 by welding. The number of ribs depends on the inner diameter of the carbon fiber roller body 1, and is generally 4-8, arranged radially. A first support sleeve 33 is fixedly installed on the outer end of the first support rib 32. The first support sleeve 33 is made of wear-resistant engineering plastic, and its outer wall is tightly fitted with the inner wall of the carbon fiber roller body 1, which can uniformly transmit the radial force borne by the carbon fiber roller body 1 to the central shaft 2.
[0041] Similarly, multiple second support ribs 39 are also fixedly installed on the outer wall of the second sliding sleeve 38. The structure and material of the second support ribs 39 are the same as those of the first support ribs 32. A second support sleeve 310 is fixedly installed on the second support ribs 39. The material and function of the second support sleeve 310 are the same as those of the first support sleeve 33. Together, they support the hollow part inside the carbon fiber roller body 1 and prevent the roller body from deforming when subjected to pressure.
[0042] like Figure 3-6 As shown, a locking mechanism is provided on one side of the first sliding sleeve 31 and the second sliding sleeve 38 to fix them in a set position. The locking mechanism includes a first fixing plate 35 sleeved on one side of the central shaft 2. The first fixing plate 35 is made of steel plate and slides in cooperation with the central shaft 2. A first limiting groove 37 is evenly opened on one side of the first fixing plate 35. A plurality of first limiting blocks 36 are fixedly installed on the first sliding sleeve 31. The first limiting blocks 36 are snapped into the first limiting groove 37. This structure can ensure that the first fixing plate 35 and the first sliding sleeve 31 move synchronously.
[0043] Meanwhile, the first fixing plate 35 is provided with a number of first locking bolts (not marked in the figure). The first locking bolts are high-strength internal hex bolts, which pass through the first fixing plate 35 and the first support rib 32 and are threadedly connected to the first limiting plate 34. By tightening the first locking bolts, the first sliding sleeve 31 can be firmly fixed to one side of the first limiting plate 34 to prevent it from shifting during operation.
[0044] like Figure 3-6 As shown, the locking mechanism also includes a second fixing plate 312 sleeved on the other side of the central shaft 2. The structure and material of the second fixing plate 312 are the same as those of the first fixing plate 35. A second limiting groove 314 is evenly provided on one side of the second fixing plate 312. A plurality of second limiting blocks 313 are fixedly installed on the second sliding sleeve 38, and the second limiting blocks 313 are snapped into the second limiting groove 314.
[0045] Meanwhile, the second fixing plate 312 is provided with a number of second locking bolts (not marked in the figure). The second locking bolts are also high-strength internal hex bolts. They pass through the second fixing plate 312 and the second support rib 39 and are threadedly connected to the second limiting plate 311, thereby fixing the second sliding sleeve 38 to one side of the second limiting plate 311. This ensures that the reinforcement component 3 remains stable during the operation of the roller body and provides reliable support for the carbon fiber roller body 1.
[0046] Working principle: During the operation of the carbon fiber micro-carving roller, the external power equipment drives the central shaft 2 to rotate through the shaft head 4. The central shaft 2 drives the carbon fiber roller body 1 to rotate synchronously through the bushing 5 and the interference fit between the bushing 5 and the carbon fiber roller body 1. When the carbon fiber roller body 1 comes into contact with the workpiece to be processed and pressure is applied (such as coating, embossing, etc.), the micro-carving texture 6 on its outer wall will form corresponding textures or patterns on the surface of the workpiece.
[0047] At this time, the carbon fiber roller body 1 generates radial pressure due to the force, which is transmitted to the first support sleeve 33 and the second support sleeve 310 inside. Since the first support sleeve 33 and the second support sleeve 310 are respectively connected to the central shaft 2 through the first support rib 32, the first sliding sleeve 31 and the second support rib 39, the second sliding sleeve 38, and the first sliding sleeve 31 and the second sliding sleeve 38 are fixed between the first limiting plate 34 and the second limiting plate 311 of the central shaft 2 by a locking mechanism, a stable support structure is formed.
[0048] The first support rib 32 and the second support rib 39 are radially distributed, which can evenly distribute the radial pressure to the central shaft 2 and avoid the pressure from concentrating in a certain part of the carbon fiber roller body 1.
[0049] The locking mechanism ensures that the first sliding sleeve 31 and the second sliding sleeve 38 are stably positioned on the central shaft 2 by engaging the first limiting block 36 with the first limiting groove 37, fixing the first locking bolt, engaging the second limiting block 313 with the second limiting groove 314, and fixing the second locking bolt. This prevents them from shifting due to force and ensures the reliability of the support.
[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
