Description

Technical Field

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

[0002] Carbon fiber is a high-strength, high-modulus fiber with a carbon content of over 90%, possessing properties such as high temperature resistance, friction resistance, thermal conductivity, and corrosion resistance. It is primarily composed of carbon elements, has a fibrous, flexible shape, and can be processed into various fabrics. Due to its graphite microcrystalline structure preferentially oriented along the fiber axis, it exhibits very high strength and modulus along the fiber axis. Carbon fiber has a low density, resulting in high specific strength and specific modulus.

[0003] A carbon fiber sizing system refers to the equipment and process used in carbon fiber production to sizing the surface of carbon fibers. The main purpose of sizing is to coat the carbon fiber surface with a thin, uniform coating called sizing agent. The functions of the sizing agent include protecting the carbon fiber surface, preventing fiber fuzzing and loosening, improving the adhesion between the fiber and resin, and improving the mechanical properties and chemical resistance of the fiber.

[0004] For example, CN202576898U describes a mechanism for enhancing the sizing effect of carbon fiber. This mechanism expels air from the carbon fiber before it enters the sizing tank, making it easy to wet. Since there are multiple sizing tanks, the carbon fiber is immersed in the tank, saturated with sizing liquid, and then squeezed dry. This process is repeated many times, resulting in a better sizing effect. The stepped distribution also facilitates the flow of sizing liquid, eliminating dead zones and sedimentation, thus enhancing the sizing effect. However, similar mechanisms for enhancing the sizing effect of carbon fiber in the above document lack a scraper to remove excess sizing liquid from the surface of the carbon fiber material, which can lead to over-coating and waste of sizing liquid. Utility Model Content

[0005] The purpose of this invention is to provide a carbon fiber sizing mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber sizing mechanism, comprising a coating component and a homogenizing component. The coating component has a combined column installed at both its left and right ends. The homogenizing component is connected to the lower end of the combined column, and a guide rail is horizontally connected to the bottom end of the combined column. The homogenizing component includes a stabilizing seat, an electric push rod, a support frame, and a scraper. The electric push rod is installed at the end of the stabilizing seat away from the combined column, and the output end of the electric push rod is connected to the support frame. A scraper is installed on the side of the support frame away from the electric push rod.

[0007] Furthermore, the coating assembly includes a coating roller, a coating sleeve, a support base, an electric telescopic rod, and a fixed base. The coating sleeve is sleeved on the surface of the coating roller, and support bases are installed at both ends of the coating roller. Electric telescopic rods are installed at both ends of the support bases, and the output end of the electric telescopic rod is connected to the fixed base.

[0008] Furthermore, the coating roller and the support base are arranged in an "H" shape, and the electric telescopic rod is horizontally installed through the upper and lower ends of the support base.

[0009] Furthermore, the electric telescopic rod and the fixed base are connected by a detachable structure, and the coating assembly is horizontally mounted between the two sets of combined columns.

[0010] Furthermore, the combined column includes a support column, a connecting seat, and an adjusting slider. The bottom of the support column is provided with a connecting seat, and the bottom of the connecting seat is provided with an adjusting slider.

[0011] Furthermore, the support column and the connecting seat are welded together, and the connecting seat and the adjusting slider are connected by a detachable structure.

[0012] Furthermore, the adjusting slider and the guide rail are connected to each other by a slotted embedded mounting structure, and the tightness between the adjusting slider and the guide rail can be controlled by adjusting the bolt structure. The coating component, the combined column and the homogenizing component are symmetrically arranged at both ends of the guide rail.

[0013] Furthermore, the side of the fixed seat away from the electric telescopic rod is connected to the support column by a detachable structure, and the end of the stable seat away from the electric push rod is connected to the support column by a detachable structure. The output end of the electric push rod is connected to the support frame by a detachable structure. The scraper is made of high-density sponge material, and the coating sleeve and the scraper are made of the same material.

[0014] This invention provides a carbon fiber sizing mechanism, which has the following beneficial effects:

[0015] 1. This utility model, by setting up homogeneous components, wherein the scraper is horizontally inserted into the side of the support frame, and utilizing the structural telescopicity of the electric push rod, can push and adjust the support frame with the scraper installed in the horizontal direction. Using the above structure, appropriate adjustments can be made according to the structural thickness of the carbon fiber plate to ensure that the two sets of homogeneous components can maintain a suitable structural position relative to the carbon fiber plate. This allows the scraper to adhere to the surface of the carbon fiber plate at a certain distance, thereby achieving different degrees of scraping treatment, avoiding excessive adhesion of the coating slurry, and reducing unnecessary waste of slurry. At the same time, since the scraper is made of high-density sponge material, the structural characteristics of the scraper material itself ensure the uniformity of scraping while avoiding unnecessary damage to the surface of the carbon fiber plate.

[0016] 2. In this utility model, the coating assembly is mounted on the guide rail by two sets of combined columns, and the coating assembly is symmetrically arranged on the left and right. The entire coating assembly is installed on the side of the support column using a fixed base. With the structural telescopicity of the electric telescopic rod, the coating roller connected to the support base and the electric telescopic rod can be adjusted for horizontal displacement. Using the above structure, the relative distance between the two sets of coating rollers can be adjusted, thereby adapting to carbon fiber plates of different thicknesses. At the same time, since the coating sleeve is made of the same material as the scraper, the problem of excessive coating slurry on the surface of the carbon fiber plate can be minimized, and the uniformity of the coating slurry can be ensured.

[0017] 3. In this utility model, the entire coating assembly is connected to the guide rail via a combination column. Due to the connection characteristics between the adjusting slider and the guide rail, and because the adjusting slider can control the tightness between itself and the guide rail through the bolt structure, this structural arrangement allows for fine adjustment of the relative distance between the two sets of combination columns that simultaneously connect the coating assembly and the homogenizing component. This ensures structural stability while providing flexibility for structural adjustment. Furthermore, the coating assembly, combination column, and homogenizing component are structurally detachable, facilitating maintenance and adjustment of the device. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1 to 4 As shown, a carbon fiber sizing mechanism includes a coating component 1 and a homogenizing component 3. The coating component 1 has combined columns 2 installed at both its left and right ends. The homogenizing component 3 is connected to the lower end of the combined columns 2, and a guide rail 4 is horizontally connected to the bottom end of the combined columns 2. The homogenizing component 3 includes a stabilizing seat 301, an electric push rod 302, a support frame 303, and a scraper 304. The electric push rod 302 is installed at the end of the stabilizing seat 301 away from the combined columns 2, and the output end of the electric push rod 302 is connected to the support frame 303. The scraper 304 is installed on the side of the support frame 303 away from the electric push rod 302. The side of the fixed seat 105 away from the electric telescopic rod 104 is connected to the support column 201 by a detachable structure, and the end of the stable seat 301 away from the electric push rod 302 is connected to the support column 201 by a detachable structure. The output end of the electric push rod 302 is connected to the support frame 303 by a detachable structure. The scraper 304 is made of high-density sponge material, and the coated sleeve 102 and the scraper 304 are made of the same material. By utilizing the structural extensibility of the electric push rod 302, the support frame 303 with the scraper 304 installed can be pushed and adjusted in the horizontal direction.

[0025] like Figures 1 to 4As shown, the coating assembly 1 includes a coating roller 101, a coating sleeve 102, a support base 103, an electric telescopic rod 104, and a fixed base 105. The coating sleeve 102 is sleeved on the surface of the coating roller 101, and the support base 103 is installed at both the left and right ends of the coating roller 101. The electric telescopic rod 104 is installed at both the upper and lower ends of the support base 103, and the output end of the electric telescopic rod 104 is connected to the fixed base 105. The coating roller 101 and the support base 103 are arranged in an "H" shape, and the electric telescopic rod 104 is horizontally installed through the upper and lower ends of the support base 103. The electric telescopic rod 104 and the fixed base 105 are connected by a detachable structure. The coating assembly 1 is horizontally mounted between two sets of combined columns 201. The entire coating assembly 1 is installed on the side of the support column 201 using the fixed base 105. At the same time, with the structural telescopicity of the electric telescopic rod 104, the coating roller 101 connected to the electric telescopic rod 104 through the support base 103 can be adjusted horizontally.

[0026] like Figures 1 to 4 As shown, the combined column 2 includes a support column 201, a connecting seat 202, and an adjusting slider 203. The bottom of the support column 201 is provided with the connecting seat 202, and the bottom of the connecting seat 202 is provided with the adjusting slider 203. The support column 201 and the connecting seat 202 are welded together, and the connecting seat 202 and the adjusting slider 203 are connected by a detachable structure. The adjusting slider 203 and the guide rail 4 are connected by a slotted embedded installation structure. The adjusting slider 203 can be adjusted and controlled to control the tightness between itself and the guide rail 4 by a bolt structure. The coating component 1, the combined column 2, and the homogenizing component 3 are symmetrically arranged at both ends of the guide rail 4. Due to the connection characteristics between the adjusting slider 203 and the guide rail 4, and because the adjusting slider 203 can be adjusted and controlled to control the tightness between itself and the guide rail 4 by a bolt structure, this structural arrangement allows for fine adjustment of the relative distance between the two sets of combined columns 2 that are simultaneously connected to the coating component 1 and the homogenizing component 3.

[0027] In summary, as Figures 1 to 4 As shown, when using this carbon fiber sizing mechanism, the carbon fiber plate to be processed is first placed vertically between two sets of opposing coating components 1. Before this, the structure of the adjusting slider 203 can be adjusted. The side of the structure can be screwed in by the bolt structure to adjust the tightness between the adjusting slider 203 and the guide rail 4, so that the coating component 1 and the homogenizing component 3 installed on the combined column 2 can move and adjust along the surface of the guide rail 4 until they are adjusted to the appropriate position.

[0028] Then, under the telescopic adjustment of the electric telescopic rod 104 connected to the fixed seat 105, the support seat 103 connected to the coating roller 101 is pushed horizontally, and the coating sleeve 102 on the surface of the coating roller 101 is pressed against the surface of the carbon fiber plate to facilitate the subsequent coating of slurry.

[0029] As the carbon fiber plate attached to the coating sleeve 102 moves vertically downward, slurry is sprayed onto the surface of the coating sleeve 102. As the coating roller 101 rotates, the slurry is evenly coated onto the surface of the carbon fiber plate. When the carbon fiber plate moves down between the two sets of homogeneous components 3, the electric push rod 302 at one end of the stabilizing seat 301 pushes the support frame 303 on which the scraper 304 is installed, so that the scraper 304 can stick to the surface of the carbon fiber plate. In this way, the excess slurry on the surface of the carbon fiber is scraped off, avoiding material waste.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
