[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides an automatic cover opening and closing device, including an L-shaped connecting frame 1 fixed on a frame. A supporting horizontal plate 2 is fixedly installed on one side of the top of the L-shaped connecting frame 1. The connection between the supporting horizontal plate 2 and the L-shaped connecting frame 1 is fixedly connected by a triangular plate 3. The entire cover opening and closing device can be installed on the frame through the L-shaped connecting frame 1. The triangular plate 3 is used to support the connection and fixation between the horizontal plate 2 and the L-shaped connecting frame 1. The bottom of the supporting horizontal plate 2 is connected to a lower rotation drive assembly 5 through two electric telescopic rods 4. A lower rotation mounting plate 6 is installed at the bottom of the lower rotation drive assembly 5. A four-axis synchronous clamping assembly 7 is fixedly installed at the bottom center. It works synchronously through two electric telescopic rods 4, which drive the lower rotation drive assembly 5 to descend. At the same time, the lower rotation mounting plate 6 drives the four-axis synchronous clamping assembly 7 to descend. After the four-axis synchronous clamping assembly 7 clamps the lid of the mobile can synchronously, the lower rotation drive assembly 5 and the electric telescopic rods 4 work synchronously. The lower rotation drive assembly 5 causes the four-axis synchronous clamping assembly 7 to rotate, removing the lid. At the same time, the electric telescopic rods 4 drive it to slowly rise, thereby realizing the separation of the lid from the mobile can. Conversely, the lid is closed.

[0023] In one embodiment, please refer to the appendix to the specification. Figure 1 As shown, a movable can body 8 is located below the four-axis synchronous clamping assembly 7. An upper open tube 9 is installed at the top center of the movable can body 8. A movable can lid 10 is threaded onto the upper open tube 9, and the diameter of the movable can lid 10 is larger than the diameter of the upper open tube 9. Because the diameter of the movable can lid 10 is larger than the diameter of the upper open tube 9, the protruding part can be stably clamped when the four-axis synchronous clamping assembly 7 is clamped, which is beneficial for stable clamping.

[0024] In one embodiment, please refer to the appendix to the specification. Figure 2 As shown, the lower rotation drive assembly 5 includes a fixed support plate 11 fixedly connected to the bottom end of the electric telescopic rod 4. A groove 12 is formed at the top center of the fixed support plate 11, and a bearing 14 is embedded in the bottom of the groove 12. A drive motor 13 is installed at the center of the fixed support plate 11, and the output end of the drive motor 13 is connected to a transmission shaft 15 that passes through the inner ring of the bearing 14. An annular slide 16 is formed inside the fixed support plate 11, and an annular opening 17 is formed at the bottom of the annular slide 16. A sliding ball 18 is provided inside the annular slide 16, and a connecting post 19 that passes through the annular opening 17 is fixedly connected to the bottom of the sliding ball 18. The rotation of the lower rotating mounting plate 6 is achieved by the drive motor 13 driving the transmission shaft 15 to rotate. The bearing 14 improves the stability during rotation. When the lower rotating mounting plate 6 rotates, the sliding ball 18 moves within the annular slide 16, and the stability of the lower rotating mounting plate 6 is improved by the action of the connecting post 19.

[0025] In one embodiment, please refer to the appendix to the specification. Figure 3 As shown, a fixing sleeve 20, which is fixedly connected to the drive shaft 15, is embedded at the top center of the lower rotating mounting plate 6. A gap is formed between the lower rotating mounting plate 6 and the fixed support plate 11. The bottom of the connecting column 19 is fixed to the lower rotating mounting plate 6. A lower mounting shell 21 is fixed at the bottom center of the lower rotating mounting plate 6. A support frame 22, which is connected to the lower rotating mounting plate 6, is fixed outside the lower mounting shell 21. The fixing sleeve 20 facilitates the connection and fixation between the drive shaft 15 and the lower rotating mounting plate 6. The lower mounting shell 21 is used for the installation and fixation of the hydraulic cylinder 23 in the four-axis synchronous clamping assembly 7.

[0026] In one embodiment, please refer to the appendix to the specification. Figure 4 As shown, the four-axis synchronous clamping assembly 7 includes a hydraulic cylinder 23 fixed inside the lower mounting housing 21. A fixing sleeve 24 is fixedly installed outside the hydraulic cylinder 23. A connecting block 25 is fixed to the output end of the hydraulic cylinder 23. Four sets of connecting seats 26 are fixedly installed on the outer side of the fixing sleeve 24. A support rod 27 is rotatably connected to the connecting seat 26. A clamping claw 28 is connected to the other end of the support rod 27. A stop block 29 is provided on the inner side of the clamping claw 28. A connecting arm 30 is rotatably connected between the connecting block 25 and the clamping claw 28. During synchronous clamping, the hydraulic cylinder 23 drives the connecting block 25 to move upward, causing the connecting arm 30 to retract the clamping claw 28. At the same time, the stop block 29 is limited at the connection between the movable can lid 10 and the upper opening pipe 9. With the drive of the lower rotation drive component 5, the movable can lid 10 is rotated to disengage from the work. Conversely, the lower rotation drive component 5 rotates in the opposite direction to install the movable can lid 10. After installation, the hydraulic cylinder 23 drives the connecting block 25 to move downward, and the clamping claw 28 is released.

[0027] In practical applications, the entire lid-opening device can be mounted on the frame using the L-shaped connecting bracket 1. Two electric telescopic rods 4 work synchronously, causing the lower rotary drive assembly 5 to descend. Simultaneously, the lower rotary mounting plate 6 drives the four-axis synchronous clamping assembly 7 to descend. After the four-axis synchronous clamping assembly 7 clamps the lid of the mobile can, the lower rotary drive assembly 5 and the electric telescopic rods 4 work synchronously. The lower rotary drive assembly 5 causes the four-axis synchronous clamping assembly 7 to rotate, removing the lid. Simultaneously, the electric telescopic rods 4 slowly raise the lid, thus detaching the lid from the mobile can. Conversely, the lid closes. This invention has a simple structure and is easy to use, achieving efficient opening and closing between the mobile can and its lid. It eliminates the need for manual operation of the lid, improving work efficiency and reducing labor costs. Furthermore, the synchronous clamping of the lid in four directions prevents it from detaching when opened.

[0028] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
