Technical Field
[0001] This utility model belongs to the technical field of winding equipment, and particularly relates to a tank inflation device and a carbon fiber winding equipment. Background Technology
[0002] In the manufacturing process of carbon fiber composite pressure vessels, winding is a core technological step. This process requires maintaining a constant air pressure within the rotating tank cavity to resist deformation caused by winding tension, ensuring uniform fiber layup and structural density. Traditional winding equipment uses a separate inflation scheme: the inflation device (including air source, pipelines, and sealing joints) is independent of the winding machine's main drive system, and pressurization is achieved through a temporary connection to the tank interface via external pipelines. However, the independent inflation unit requires additional configuration of a drive motor, rotary sealing mechanism, and support frame, which not only increases equipment size and manufacturing costs but also occupies production line space. Each time the tank is changed, the inflation device and drive device on the tank must be removed separately, which is complex and time-consuming, resulting in decreased production efficiency. Utility Model Content
[0003] In view of this, the present invention provides a tank inflation device and a carbon fiber winding equipment to solve the problems of increased cost and low production efficiency caused by the split inflation scheme in the prior art.
