Description

Technical Field

[0001] This utility model is a carbon fiber drying device, belonging to the technical field of carbon fiber drying equipment. Background Technology

[0002] Carbon fiber is a composite material containing high-strength, high-modulus fibers with a carbon content of over 95%. Surface treatment of carbon fiber is a crucial step in its production process, specifically comprising five steps: electrolytic surface treatment, washing, drying, sizing, and drying again. Drying is the most critical step in the carbon fiber surface treatment process.

[0003] Patent No. CN220083596U discloses a carbon fiber drying device. Hollow plates one and two are slidably mounted on the inner walls of the front and rear sides of a drying chamber. Four guide ports are opened on the front side of the drying chamber, and an adjustment component is installed within these ports and connected to hollow plates one and two. Strip-shaped openings are opened on both sides of the drying chamber, enabling continuous drying of the carbon fiber. The device can also change the movement trajectory of the carbon fiber within the drying chamber, thereby increasing the drying time and effectively improving the drying effect. Furthermore, it can recover and reuse heat within the drying chamber, effectively reducing the energy consumption required for drying carbon fiber. However, the hot air blower is fixed in position, limiting the drying range, and the overall drying efficiency needs further improvement. There is an urgent need for a carbon fiber drying device to address these problems. Utility Model Content

Second U-shaped plates 18 are installed on the shaft ends of the two electric push rods 5 respectively. Second guide rollers 19 are rotatably installed inside the two second U-shaped plates 18 respectively. A mounting plate 25 is installed above the moving end of the linear motor 22. Second rack plates 26 are installed on the left and right sides of the mounting plate 25 respectively. This design solves the problems of the fixed position of the hot air blower in the original device, the large limitation of the drying range, and the need to further improve the overall drying efficiency.

[0021] In the first embodiment of this utility model: two linear motors 22 and two square frames 2 are respectively provided. The two square frames 2 are installed on the left and right sides of the drying chamber 1, and the two linear motors 22 are installed in the middle of the upper and lower sides of the drying chamber 1. By setting two linear motors 22, it is convenient to drive multiple second hot air blowers 8 and multiple first hot air blowers 7 to move. Multiple second rack plates 26 are respectively meshed with multiple gears 23. Fourth U-shaped plates 28 are respectively installed on the outer side of the multiple second rack plates 26. Second hot air blowers 8 are respectively installed on the outer side of the horizontal end of the multiple fourth U-shaped plates 28. The air outlets of the multiple second hot air blowers 8 pass through the horizontal ends of the multiple fourth U-shaped plates 28. Two second through slots 10 and two third through slots 11 are respectively provided on the upper and lower sides of the drying chamber 1. First through slots 9 are respectively provided on the left and right sides of the drying chamber 1. Support columns 4 are respectively installed at multiple corners below the drying chamber 1. A transparent cover plate 3 is movably installed on the front side of the drying chamber 1. By setting two first through slots 9, it is convenient to insert and exit carbon fibers. Inside the drying chamber 1, cylinders 13 are installed on the upper and lower sides respectively. Rectangular plates 12 are installed on the shaft ends of the two cylinders 13 respectively. The inner sides of the two rectangular plates 12 are respectively provided with two fourth through grooves 14 and two fifth through grooves 15. Multiple first U-shaped plates 16 are installed on the inner sides of the two rectangular plates 12 respectively. First guide rollers 17 are rotatably installed inside the multiple first U-shaped plates 16. The multiple first guide rollers 17 are set to facilitate the guidance of carbon fibers. The air outlets of multiple second hot air blowers 8 are respectively sealed with second air ducts 21, and the air outlets of multiple first hot air blowers 7 are respectively sealed with first air ducts 20.

At this time, multiple electric push rods 5 can be activated to move the multiple second guide rollers 19 to initially limit the carbon fiber. Then, two cylinders 13 are activated to drive the two rectangular plates 12 to move down, so that the multiple first guide rollers 17 limit the carbon fiber a second time. Then, the transparent cover plate 3 is reset, and multiple second hot air blowers 8 and multiple first hot air blowers 7 are activated to allow hot air to flow. The carbon fiber is dried by air blowing from multiple first air ducts 20 and multiple second air ducts 21. Then, the moving ends of two linear motors 22 reciprocate linearly, which drives two mounting plates 25 to move. Multiple second rack plates 26 reciprocate, which drives multiple gears 23 to rotate in both directions. The rotation of multiple gears 23 drives multiple first rack plates 24 to reciprocate along multiple sliding plates 6, which in turn drives multiple second hot air blowers 8 and multiple first hot air blowers 7 to reciprocate, thereby drying the carbon fiber more thoroughly. The operator can connect the left end of the carbon fiber to an external winding device to control the movement speed of the carbon fiber and thus control the drying time.
