Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of composite material molding, and specifically is a gas pressure driven automatic rotating adjustable heating plate device with reasonable structure and simple adjustment, which can adapt to the requirements of flat plate heating and S-type heating in the composite material molding process. Background Art
[0002] The dry process of preparing composite materials (prepregs) requires heating and pressurizing the fibers and resins. This causes the resin to melt and fuse with the fibers under pressure, allowing the resin molecules to wrap around each fiber, thus preparing the composite material (prepreg). The current composite material preparation (dry process) often uses several sets of hot pressing rollers and several sets of heating plates to alternately press and heat (keep the heat) the fibers and resin during the preparation process. That is, the fibers and resin 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, as shown in the attached figure. Figure 1 shown.
[0003] However, for high viscosity resins that are not conducive to penetration or when the prepreg surface density is high, 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 once, then enter the heating plate, and then are re-wound around the upper and lower heating rollers once. This prepreg preparation process is called an S-type process, as shown in the attached figure. Figure 2 As shown in the figure, in the S-shaped process, the heating plate must be tilted along the path to ensure proper lamination between the fiber and the resin, and its angle or height must be adjustable. Therefore, an adjustable heating plate assembly is required to achieve the transition between the straight and S-shaped process paths. Summary of the Invention
[0004] In view of the shortcomings and deficiencies in the existing technology, the utility model proposes a gas pressure driven automatic rotating adjustable heating plate device with reasonable structure, simple adjustment, and capable of adapting to the needs of flat-plate heating and S-type heating in the composite material molding process.

[0009] The rotary lifting and limiting mechanism of the present invention is preferably installed on the horizontal X-axis of the heating plate to improve the lifting and limiting stability of the heating plate.
[0010] When the utility model is working, the inclination angle of the heating plate can be adjusted according to the processing needs, so that the heating plate meets the requirements of the linear process flow or the S-shaped process flow.

At this time, the lifting base and the adjustable stroke cylinder adjustment nut are locked; in addition, when switching between different processes, when the heating plate is currently in a linear process, the adjustable stroke cylinder is simultaneously reversed, and the adjustable stroke cylinder is adjusted from a retracted state to a lifted state.

When the cylinder reaches the limit position, it is now in a linear process.

It has significant advantages such as reasonable structure, simple operation, and stable adjustment. BRIEF DESCRIPTION OF THE DRAWINGS
