Description

Technical Field

[0001] The present application relates to the technical field of composite material preparation, and in particular to an air pressure driven automatic lifting and adjustable heating plate device. Background Art

[0002] The dry preparation process of composite materials (prepregs) requires heating and pressurizing the fibers and resins to melt the resin and fuse it with the fibers under pressure, so that the resin molecules wrap each fiber, thereby preparing a composite material (prepreg).

[0003] In the current composite material preparation (dry process), several groups of hot pressing rollers and several groups of heating plates are used to alternately press and heat (keep warm) the fibers and resins in the preparation process. That is, the fibers and resins pass through the middle of the heating rollers, enter the heating plates for heating, and then enter the heating rollers for pressing, and so on. This prepreg preparation process is a linear process (such as Figure 5 ).

[0004] However, for high-viscosity resins that are not conducive to penetration or when the prepreg surface density is large, the number of heating rollers and heating plates required for pressing and heating will increase accordingly. Therefore, in order to ensure better heating and pressurizing effects under limited conditions, a process method has been developed in which the fiber and resin are pre-wound around the upper and lower heating rollers, then enter the heating plate, and then are re-wound around the upper and lower heating rollers. This prepreg preparation process is an S-type process (such as Figure 6 ).

[0005] In the S-type process, the heating plate needs to be tilted along the path to ensure the adhesion between the fiber and the resin, and its angle or height needs to be adjustable. Therefore, a set of adjustable heating plate devices is required to realize the conversion of the paths of the straight-line and S-type processes. Summary of the invention
