Embodiment 1

[0051] Such as Figure 1-4 shown.

[0052] A method for manufacturing a thermosetting carbon fiber plate for wind blades, such as figure 1 As shown, it includes the following steps:

[0053] Firstly, the carbon fiber is introduced from the tension creel 1 into the sealing and dipping box 2 for impregnation. The sealing and dipping box has a fully automatic feeding device 3 that automatically injects glue according to the detected pressure and glue position in the sealing and dipping box. , to ensure that the carbon fiber is fully impregnated under the set pressure; the pressure in the sealed dipping box is 0.01-3.0MPA. The working principle of fully automatic feeding device 3 is as follows image 3 As shown, the mixing ratio of epoxy, polyurethane and thermoplastic resin is 100:20 to 100:200, and the feeding range is 0.01L~20.0L;

[0054] Secondly, the impregnated carbon fiber enters the curing mold 5 for three-stage heating and curing to obtain a carbon fiber plate, and a...

Embodiment 2

[0058] Such as Figure 1-4 shown.

[0059] A production line for manufacturing thermosetting carbon fiber panels for wind blades, such as figure 1 As shown, it includes:

[0060] A tension creel 1, the tension creel 1 is used to provide a continuous flow of raw materials for the manufacture of carbon fiber panels;

[0061] A sealed dipping box 2, the sealed dipping box 2 is used for dipping the carbon fibers drawn from the tension creel 1, so that the surface of the carbon fiber filaments is bonded with thermosetting adhesive, laying the foundation for the next step of thermosetting molding; By controlling the amount of glue in the sealed dipping box 2, the internal pressure is controlled between 0.01-3.0MPA;

[0062] A fully automatic feeding device 3 (according to image 3 self-designed and manufactured according to the requirements), the fully automatic feeding device 3 is used to inject the stirred heat-curing glue into the sealing dipping box 2, and realize the heat-c...

Abstract

The invention provides a manufacturing method and production line for a thermoset carbon fiber plate for a wind vane. The manufacturing method is characterized by comprising the following steps that firstly, carbon fibers are guided into a sealed impregnation box (2) to be impregnated from a tension creel (1), and the sealed impregnation box is provided with a full-automatic proportioning and feeding device (3) which can conduct glue injection automatically according to the detected pressure and glue positions in the sealed impregnation box; secondly, the impregnated carbon fibers are pushed into a curing mold (5) to be heated, cured and shaped, so that a carbon fiber plate is obtained, and a centering correction mechanism is additionally installed at the outlet end of the curing mold (5), so that the cured carbon fiber plate is pulled out of the curing mold (5) with the set straightness; and thirdly, the cured carbon fiber plate is guided into a surface treatment device (6) to be subjected to surface polishing, and the surface roughness of the polished carbon fiber plate is kept between 0.3-1.0 micrometer; and fourthly, the carbon fiber plate subjected to surface polishing is pulled by a pulling mechanism (7) to be conveyed into a rolling mechanism to be rolled. The manufacturing method is simple, the production efficiency is high, and the quality is good.

Description

technical field [0001] The invention relates to a wind power generation technology, in particular to a carbon plate technology for reinforcing wind blades of more than 3 megawatts, specifically a manufacturing method and production line for a thermosetting carbon fiber plate for wind blades. Background technique [0002] As we all know, my country's wind energy resources that can be developed and utilized are about 253 million kilowatts, and the effective wind time percentage of the two main wind belts from Xinjiang, Inner Mongolia to the northeast and southeast coast is above 70%. Therefore, my country has a good natural environment and resources for the development of wind energy. condition. In recent years, with the improvement of power grid coverage, my country has established more than 20 wind farms in Xinjiang, Inner Mongolia, Guangdong and other regions, with a total installed capacity of 302MW, which has played a very good role in alleviating the contradiction of loca...
