Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides an automatic wrapping device for sealing petri dishes, comprising a workbench 1, a motor 2 fixedly connected inside the workbench 1, a roller 3 fixedly mounted at the output end of the motor 2, a belt 4 mounted on the outer wall of the roller 3, a roller 5 mounted on the inner wall of the belt 4, a connecting shaft 6 fixedly connected inside the roller 5, the outer wall of the connecting shaft 6 rotatably connected inside the workbench 1, a gear 7 fixedly connected to the outer wall of the connecting shaft 6, a gear ring 8 meshing with the tooth end of the gear 7, a ball bearing 9 fixedly connected to the lower surface of the gear ring 8, the outer wall of the ball bearing 9 slidably connected inside the workbench 1, a limit block 10 slidably connected to the outer wall of the gear ring 8, the lower surface of the limit block 10 fixedly connected to the upper surface of the workbench 1, a winding tube 11 mounted on the upper surface of the gear ring 8, and a support assembly mounted on the lower surface of the workbench 1 for auxiliary support.

[0025] Specifically, the workbench 1 fixes the motor 2. Starting the motor 2 drives the first roller 3 to rotate, which in turn drives the belt 4 to rotate. The belt 4 drives the second roller 5 to rotate, which in turn drives the connecting shaft 6 to rotate. While the connecting shaft 6 is rotating, the workbench 1 supports it. The connecting shaft 6 drives the gear 7 to rotate, which in turn drives the gear ring 8 to rotate. While the gear ring 8 is rotating, the limit block 10 limits its movement. The gear ring 8 drives the ball bearing 9 to slide, which supports it. The gear ring 8 also drives the unwinding tube 11 to rotate, which holds the protective film.

[0026] Reference Figure 3 The support assembly includes a support column 12, the upper surface of which is fixedly connected to the lower surface of the workbench 1, and a support table 13 is fixedly connected to the lower surface of the support column 12.

[0027] Specifically, the support column 12 provides fixed support for the workbench 1 and the support table 13 is fixed to the support column 12. The support table 13 is used to support the device.

[0028] Reference Figure 4 and Figure 5 A hydraulic cylinder 14 is fixedly connected to the upper surface of the support table 13. A sliding block 15 is fixedly connected to the output end of the hydraulic cylinder 14. A limit plate 16 is slidably connected to the lower surface of the sliding block 15. The lower surface of the limit plate 16 is fixedly connected to the upper surface of the support table 13. A sliding column 17 is fixedly connected inside the sliding block 15. A connecting plate 18 is slidably connected to the outer wall of the sliding column 17. A placement platform 19 is fixedly connected to the upper surface of the connecting plate 18. A sliding column 20 is fixedly connected to the lower surface of the placement platform 19. A sleeve 21 is slidably connected to the outer wall of the sliding column 20. The outer wall of the sleeve 21 is fixedly connected to the inside of the support table 13. A fixed platform 22 is fixedly connected to the upper surface of the placement platform 19.

[0029] Specifically, the support table 13 fixes the hydraulic cylinder 14. Activating the hydraulic cylinder 14 causes the sliding block 15 to slide. While the sliding block 15 slides, the limiting plate 16 limits its movement. The sliding block 15 fixes the sliding column 17. The sliding column 17 moves the connecting plate 18, which has an arc-shaped groove inside. The sliding column 17 slides within this groove, moving the connecting plate 18. The connecting plate 18 moves the placement platform 19, which in turn moves the sliding column 20. While the sliding column 20 slides, the sleeve 21 limits its movement. The sliding column 20 moves the fixing platform 22, which limits the movement of the culture dish.

[0030] Working principle: When the wrapping device is needed, the culture dish to be wrapped is first placed on the upper surface of the fixed platform 22. The hydraulic cylinder 14 is activated to drive the sliding block 15 to slide on the upper surface of the limiting plate 16, which in turn drives the sliding column 17 to slide inside the connecting plate 18. While the sliding column 17 is sliding, the placement platform 19 is moved, which in turn drives the sliding column 20 to slide on the inner wall of the sleeve 21, thereby achieving the effect of lifting the culture dish. When the culture dish is raised to the middle of the inner groove of the worktable 1, the film on the outer wall of the unwinding tube 11 is attached to the outside of the culture dish. At this time, the motor 2 drives the roller 3 to rotate, which in turn drives the belt 4 to rotate, and at the same time drives the roller 5 to rotate. While the roller 5 is rotating, the connecting shaft 6 rotates inside the worktable 1, which in turn drives the gear 7 to rotate, and at the same time drives the gear ring 8 to rotate. The limiting block 10 limits the gear ring 8, which in turn drives the ball 9 to rotate inside the worktable 1, achieving the effect of automatic film wrapping. This device can not only automatically lift the culture dish and improve efficiency, but also achieve the effect of automatic film wrapping, improving the quality and efficiency of film wrapping.
