For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0020] like Figure 1-6 As 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.

[0021] The mounting truss 1 is arranged horizontally and is designed as a long strip.

[0022] The slide rail mounting plate 8 is fixedly mounted on the lower side 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 slider 9, the lifting plate 11 is fixedly connected to the slider 10, and the piston rod of the cylinder 12 is fixedly connected to the lifting plate 11. Therefore, the piston rod of the cylinder 12 moves downward, and with the help of the slider 10 and the slide rail 9, the lifting plate 11 is stably driven to move downward; conversely, the piston rod of the cylinder 12 moves upward, and the lifting plate 11 is stably driven to move upward.

[0023] The lifting plate 11 is fixedly connected to the swing arm mounting plate 2. The top of the swing arm mounting plate 2 is fixedly connected to the limit plate 13, and the limit plate 13 cooperates with the upper side of the mounting truss 1. Therefore, when the lifting plate 11 moves upward, the swing arm mounting plate 2 moves upward accordingly; when the lifting plate 11 moves downward, the swing arm mounting plate 2 moves downward accordingly, and when it descends to a certain distance, it is limited by the limit plate 13, that is, the descending distance of the swing arm mounting plate 2 is limited.

[0024] One end of the first connecting swing arm 3 is hingedly arranged 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 arranged 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. Further, the first connecting swing arm 3 and the second connecting swing arm 4 are arranged in parallel, and when the first connecting swing arm 3 and the second connecting swing arm 4 are both in a vertical downward state, the first connecting swing arm 3 and the second connecting swing arm 4 are symmetrical to each other.

[0025] One side wall of the swing arm connecting rod 5 is fixedly connected to the top of the first S-shaped plate 6, and the bottom of the first S-shaped plate 6 is fixedly connected to the bottom film 7. The other side wall of the swing arm connecting rod 5 is fixedly connected to the top of the second S-shaped plate 14, and the bottom of the second S-shaped plate 14 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, and carton board channels are left between the input port lower plate 15 and the input port upper plate 16, and 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 is conducive to the spatial arrangement between the structures.

[0026] In summary, when the piston rod of the cylinder 12 moves downward, it drives the lifting and pulling plate 11, the swing arm mounting plate 2, the first connected swing arm 3, the second connected 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 limiting plate 13; when the piston rod of the cylinder 12 moves upward, it drives the lifting and pulling plate 11, the swing arm mounting plate 2, the first connected swing arm 3, the second connected 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.

[0027] 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 bottom film 7 and the lower plate 15 of the input port can be driven to swing by the swinging movement of the first connecting swing arm 3 and the second connecting swing arm 4, 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 of the position (the bottom film 7 and the lower plate 15 of the input port cannot swing but can only move up and down).

[0028] A control method for a bottom film lifting device, specifically comprising: Monitor the glueing or stapling action of the carton stitching machine.

[0029] When the box stitching machine is gluing boxes, the piston rod of the control cylinder 12 contracts, driving the lifting and pulling 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 film 7 and the input port lower plate 15 move upward, thereby retracting the bottom film 7 to facilitate the gluing work; the distance sensor on the input port upper plate 16 detects the position of the input port lower plate 15 in real time, and when the height of the carton board channel is 0, the control cylinder 12 stops contracting.

[0030] When the carton nailing machine is nailing boxes, the piston rod of the control cylinder 12 is extended outward, driving 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 film 7 and the input port lower plate 15 move downward, thereby opening the carton board channel to facilitate the nailing work; the distance sensor on the input port upper plate 16 detects the position of the input port lower plate 15 in real time, and based on the thickness of the carton board, the height of the carton board channel is customized. When it is detected that the height of the carton board channel reaches the set value, the control cylinder 12 stops extending.

[0031] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the above disclosed methods and technical contents without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the present invention without departing from the content of the technical solution of the present invention should be included in the protection scope of the present invention.
