Description

Technical Field

[0001] The present application relates to the technical field of carbon fiber tube production equipment, and in particular to a carbon fiber tube covering device and method. Background Art

[0002] Carbon fiber tubes, due to their lightweight and high strength, have been widely used in aerospace, automotive, and other fields. However, the traditional production of carbon fiber tubes presents many challenges, particularly in the coating process. Efficiently and uniformly coating the carbon fiber raw material sheet on the mandrel is a key issue. While the carbon fiber tube coating equipment currently available on the market can generally meet production needs, there is still significant room for improvement in terms of coating quality. To improve the coating quality of carbon fiber tubes, manual or semi-automatic coating methods are typically used in related technologies. Specifically, common methods include: 1) manually wrapping the carbon fiber raw material sheet around the mandrel. While this method is simple and easy, it is labor-intensive, inefficient, and prone to uneven coating. 2) using simple mechanical auxiliary tools, such as manual rollers or fixed brackets. These tools can partially reduce the burden on workers, but cannot completely avoid quality fluctuations caused by human factors. 3) using equipment such as electric rollers or conveyor belts to assist in the coating process. This type of equipment can improve production efficiency to a certain extent, but due to the lack of precise control mechanisms, it is still difficult to ensure the quality of the coating. Although various existing methods and technical means have solved some of the problems of carbon fiber tube coating to varying degrees, they generally have the following defects: the coating accuracy is not high, and problems such as uneven coating tightness and inconsistent thickness are prone to occur, which affect the quality and performance of the final product; therefore, there is an urgent need to develop a device that can improve the quality of carbon fiber tube coating to overcome the shortcomings of the existing technology.
