[0002] Carbon fiber is a new fiber material with high strength and high modulus, containing more than 90% carbon. The manufacturing process of carbon fiber involves carbonizing soft organic polymer fibers to convert them into carbon fiber. This material has many excellent properties, including high strength, low density, high temperature resistance, corrosion resistance, good electrical and thermal conductivity, etc. Carbon fiber pre - impregnation refers to a mixture of continuous carbon fiber, carbon fiber fabric or chopped carbon fiber impregnated with a resin matrix under certain process conditions, which is a main material method for manufacturing advanced composite structural parts.

The connecting bracket 64 is rotatably connected to one side of the upper bearing bracket 62. The cylinder 63 adjusts the distance between the upper and lower hot pressing rollers 65 by the extension or contraction of the piston rod.

[0026] Moreover, a yarn spreading carbon cloth unwinding roller 8 is arranged at the top of the first mounting bracket 1. A yarn spreading carbon cloth 05 is wound on the yarn spreading carbon cloth unwinding roller 8. A cloth guiding roller assembly 9 is arranged on one side of the yarn spreading carbon cloth unwinding roller 8. The cloth guiding roller assembly 9 is used for the transmission of the yarn spreading carbon cloth 05.

[0027] In addition, a fiber guiding roller assembly 4 is arranged in the middle of the first mounting bracket 1. A first hot pressing roller assembly 6 is arranged on one side of the fiber guiding roller assembly 4. A carbon fiber unwinding roller 3 is arranged on the other side of the fiber guiding roller assembly 4 away from the first hot pressing roller assembly 6. The carbon fiber unwinding roller 3 is used for the transmission of carbon fiber.

[0028] Moreover, a lowering winding roller 5 is provided at the bottom of the first mounting bracket 1. A protective film 06 is wound around the lowering winding roller 5. A film guiding roller assembly 7 is provided on one side of the lowering winding roller 5. A carbon cloth 04 is output between the hot pressing rollers 65 of the first hot pressing roller assembly 6. The carbon cloth 04 is extruded by the hot pressing roller assembly 6 from the spread yarn carbon cloth 05, the protective film 06 and the carbon fiber through the hot pressing rollers 65.

[0029] Meanwhile, the first rolling unit 02 includes a second mounting bracket 10. Second hot pressing roller assemblies 11 are arranged horizontally and uniformly on the second mounting bracket 10. The second hot pressing roller assemblies 11 are convenient for performing the second hot pressing.

The lowering winding roller 5 at the bottom unwinds the protective film 06 and then transmits it to the first hot pressing roller assembly 6 through the film guiding roller assembly 7. Then, while the hot pressing rollers 65 of the first hot pressing roller assembly 6 are rolling for transmission, they perform hot pressing in alignment, so that the spread yarn carbon cloth 05 and the protective film 06 are hot pressed and impregnated on both sides of the carbon fiber to form the carbon cloth 04. And the carbon cloth 04 is transmitted to the heating plate frame 2, and the heating plate frame 2 heats both sides of it synchronously, making the impregnation effect better.

[0034] After the carbon cloth 04 is transmitted from the yarn spreading and combining unit 01, it enters the first rolling unit 02. During this process, it is hot-pressed by a plurality of second hot pressing roller assemblies 11, so that the carbon cloth 04 is better impregnated. Then it enters the second rolling unit 03 for the final rolling work, which is carried out by the third hot pressing roller assembly 13. Then, the carbon cloth 04 is guided to the carbon cloth winding mechanism 15 on one side by the traction pressing roller assembly 14 for winding, and the winding film mechanism 16 is used to wind up the used protective film 06 material.

[0035] In the present utility model, the yarn spreading and combining unit 01 is provided to impregnate the composite material with carbon fiber, and the strength of the composite carbon cloth 04 is higher through the yarn spreading carbon cloth 05 and the protective film 06.
