[0030] Specific usage method and function of this embodiment:

[0031] In this utility model, as Figure 1As shown, the fixed bearing plate 2 is in a truncated state before and after. The composite film to be folded is located between the top end face of the fixed bearing plate 2 and the lifting and pressing roller 7. When the lifting and pressing roller 7 is adjusted in height, the lifting adjustment cylinder 4 is rotated forward to be in threaded engagement with the lifting bearing rod 3, causing the lifting adjustment cylinder 4 to rise through threaded engagement. The lifting adjustment cylinder 4 drives the moving lifting rod 5 to rise synchronously through the bearing. The moving lifting rod 5 drives the lifting and pressing roller 7 to rise synchronously, and the lifting and pressing roller 7 drives the roller bearing rod 8 to rise synchronously, thereby realizing the upward adjustment of the lifting and pressing roller 7. The lifting adjustment cylinder 4 is rotated reversely to be in threaded engagement with the lifting bearing rod 3, causing the lifting adjustment cylinder 4 to descend through threaded engagement. The lifting adjustment cylinder 4 drives the moving lifting rod 5 to descend synchronously through the bearing. The moving lifting rod 5 drives the lifting and pressing roller 7 to descend synchronously, and the lifting and pressing roller 7 drives the roller bearing rod 8 to descend synchronously, thereby realizing the downward adjustment of the lifting and pressing roller 7. At the same time, the composite film guide plate 10 always contacts the top end face of the fixed bearing plate 2 under its own weight, thus facilitating the guiding of the composite film to be folded. Note that the guide plate anti - detachment cylinder 11 does not lock the composite film guide plate 10, but only limits and prevents the detachment of the composite film guide plate 10. Therefore, the guiding adjustment cylinder 9 can move up and down inside the double - round - head rectangular hole of the composite film guide plate 10. When the position of the composite film guide plate 10 is adjusted, the guiding adjustment cylinder 9 is rotated to be in threaded engagement with the moving lifting rod 5 and the roller bearing rod 8, causing the guiding adjustment cylinder 9 to move through threaded engagement. The guiding adjustment cylinder 9 drives the composite film guide plate 10 to move synchronously through the guide plate anti - detachment cylinder 11, thereby realizing the position adjustment of the composite film guide plate 10.

[0032] Embodiment Two:

[0033] The difference from Embodiment One is that the regular hexagon groove of the lifting bearing rod 3 can also be set as a regular heptagon groove. Thus, the lifting bearing rod 3 needs to be rotated by a special tool that matches the regular heptagon groove, preventing non - staff from rotating and disassembling the lifting bearing rod 3.

[0034] Embodiment Three:

[0035] The difference from Embodiment One is that the regular hexagon groove of the lifting guide rod 6 can also be set as a regular heptagon groove. Thus, the lifting guide rod 6 needs to be rotated by a special tool that matches the regular heptagon groove, preventing non - staff from rotating and disassembling the lifting guide rod 6.
