[0028] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0030] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0031] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0032] like Figure 1-6As shown, this embodiment provides a bottom film lifting device, which consists of a mounting truss 1, a lifting assembly (the lifting assembly consists of a slide rail mounting plate 8, a slide rail 9, a slider 10, a lifting pull plate 11, a cylinder 12, etc.), a swing arm mounting plate 2, a first connecting swing arm 3, a second connecting swing arm 4, a swing arm connecting rod 5, a first S-shaped plate 6, a bottom film 7, a limit plate 13, a second S-shaped plate 14, an input port lower plate 15, an input port upper plate 16, and the like.

[0033] The mounting truss 1 is arranged horizontally and is designed as a long strip.

[0034] The slide rail mounting plate 8 is fixedly mounted on the underside of the mounting truss 1. The slide rail 9 is vertically mounted on the slide rail mounting plate 8. The slider 10 is slidably connected to the slide rail 9. The lift plate 11 is fixedly connected to the slider 10. The piston rod of the cylinder 12 is fixedly connected to the lift plate 11. Therefore, when the piston rod of the cylinder 12 moves downward, the lift plate 11 is stably driven downward by the action of the slider 10 and the slide rail 9. Conversely, when the piston rod of the cylinder 12 moves upward, the lift plate 11 is stably driven upward.

[0035] The lifting plate 11 is fixedly connected to the swing arm mounting plate 2. A stop plate 13 is fixedly connected to the top of the swing arm mounting plate 2, which engages the upper side of the mounting truss 1. Therefore, when the lifting plate 11 moves upward, the swing arm mounting plate 2 moves upward with it; when the lifting plate 11 moves downward, the swing arm mounting plate 2 moves downward with it. When it descends a certain distance, the stop plate 13 stops it, effectively limiting the distance the swing arm mounting plate 2 can descend.

[0036] One end of the first connecting swing arm 3 is hingedly mounted on the swing arm mounting plate 2, and the other end is hingedly connected to one end of the swing arm connecting rod 5. One end of the second connecting swing arm 4 is hingedly mounted on the swing arm mounting plate 2, and the other end is hingedly connected to the other end of the swing arm connecting rod 5. Furthermore, the first connecting swing arm 3 and the second connecting swing arm 4 are arranged in parallel. When the first connecting swing arm 3 and the second connecting swing arm 4 are both in a vertical downward position, the first connecting swing arm 3 and the second connecting swing arm 4 are symmetrical to each other.

[0037] One sidewall of the swing arm connecting rod 5 is fixedly connected to the top of the first S-shaped plate 6, the bottom of which is fixedly connected to the bottom film 7. The other sidewall of the swing arm connecting rod 5 is fixedly connected to the top of the second S-shaped plate 14, the bottom of which is fixedly connected to the input port lower plate 15. The bottom of the slide rail mounting plate 8 is fixedly connected to the input port upper plate 16. Carton board channels are left between the input port lower plate 15 and the input port upper plate 16, as well as between the bottom film 7 and the input port upper plate 16. It should be noted that the provision of the first S-shaped plate 6 and the second S-shaped plate 14 facilitates the spatial arrangement between the structures.

[0038] In summary, when the piston rod of the cylinder 12 moves downward, it drives the lifting plate 11, the swing arm mounting plate 2, the first connecting swing arm 3, the second connecting swing arm 4, the swing arm connecting rod 5, the first S-shaped plate 6 and the second S-shaped plate 14 to move downward, so that the bottom membrane 7 and the input port lower plate 15 move downward and are limited by the limit plate 13; when the piston rod of the cylinder 12 moves upward, it drives the lifting plate 11, the swing arm mounting plate 2, the first connecting swing arm 3, the second connecting swing arm 4, the swing arm connecting rod 5, the first S-shaped plate 6 and the second S-shaped plate 14 to move upward, so that the bottom membrane 7 and the input port lower plate 15 move upward and are limited by the input port upper plate 16.

[0039] In the process of the carton board passing through the carton board channel to the position above the bottom film 7, if the carton board is not in a flat position, the first connecting swing arm 3 and the second connecting swing arm 4 will swing the bottom film 7 and the lower plate 15 of the input port, so that the position of the carton board can be flexibly adjusted, thereby avoiding the situation where the carton board is stuck due to rigid adjustment (the bottom film 7 and the lower plate 15 of the input port cannot swing but can only move up and down).

[0040] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the methods and technical content disclosed above to make many possible variations and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations. Therefore, any equivalent variations based on the shape, structure, and principle of the present invention that do not depart from the content of the present invention are intended to be covered by the scope of protection of the present invention.
