[0031] Such as Figure 1 and Figure 2As shown in the figure, a finished egg tray demolding device includes a frame 1, a rotating shaft 2, a connecting arm 3, a connecting rod 4, a tray 5, a limiting mechanism and a power mechanism. A bearing seat 21 is fixedly arranged on the frame 1, the rotating shaft 2 is rotatably arranged on the bearing seat 21, one end of the connecting arm 3 is fixedly connected to the rotating shaft 2, the other end of the swing 3 is rotatably connected to the connecting rod 4, the tray 5 is fixedly arranged on the connecting rod 4, an air cavity is arranged inside the tray 5, a plurality of air holes are formed on one side of the tray 5 away from the connecting rod 4, the air holes are communicated with the air cavity, a trachea is connected to the other side of the tray 5, the trachea is communicated with the air cavity, and the trachea can suck air or blow air into the air cavity. The limiting mechanism is arranged between the frame 1 and the connecting rod 4 and is used for limiting the connecting rod 4 and the tray 5 so that the tray 5 can only rotate within a range of 90 degrees, enabling the tray 5 to be in a vertical state and a horizontal state. The power mechanism is arranged on the frame 1, and the power mechanism is in transmission connection with the rotating shaft 2 to drive the rotating shaft 2 to rotate. In the present utility model, after the egg tray is produced by the molding machine, since a plurality of egg tray templates on the molding machine are uniformly arranged along the circumferential direction, when one template adsorbs the paper pulp slurry, the egg tray on the other template is processed and needs to be removed. At this time, the power mechanism drives the rotating shaft 2 to rotate, thereby driving the connecting arm 3, the connecting rod 4 and the tray 5 to rotate. The limiting mechanism limits the rotation angle of the tray 5 so that the tray 5 rotates between the vertical state and the horizontal state. When the tray 5 is in the vertical state, the side of the tray 5 provided with the air holes is attached to the template of the egg tray processed by the molding machine, and both sides of the finished egg tray are respectively in contact with the template and the tray 5. At this time, the trachea sucks air to suck the egg tray onto the tray 5. The power mechanism continues to drive the tray 5 to rotate so that the tray 5 is in the horizontal state. At this time, the trachea blows air to blow the egg tray on the tray 5 onto the ground or the conveyor, completing the demolding of the egg tray. The whole process does not require manual intervention and can automatically demold the egg tray, which is more convenient and fast.
[0032] It should be noted that the trachea includes a main pipe and branch pipes. There is one main pipe, and the main pipe is connected to the tray 5. There are two branch pipes, and both branch pipes are connected to the main pipe. One branch pipe is connected to an air compressor for sucking air to suck the egg tray onto the tray 5, and the other branch pipe is connected to an air pump for blowing air to blow the egg tray off the tray 5. Solenoid valves are arranged on the branch pipes to control the on-off of the air paths of the branch pipes.
[0033] Further, the power mechanism includes a power component and a connecting rod component. The power component is fixedly arranged on the frame 1. The power component includes a driving motor 6 and a speed reducer 7. The speed reducer 7 is fixedly arranged on the frame 1. The input shaft of the speed reducer 7 is connected to the driving motor 6, and the output shaft of the speed reducer 7 is connected to the connecting rod component. The connecting rod component is respectively connected to the power component and the rotating shaft 2. The connecting rod component includes a first transmission rod 8, a second transmission rod 9 and a rocker arm 10. One end of the first transmission rod 8 is fixedly connected to the output shaft of the speed reducer 7. The first transmission rod 8 rotates around the output shaft of the speed reducer 7. The other end of the first transmission rod 8 is rotatably connected to the second transmission rod 9. One end of the second transmission rod 9 away from the first transmission rod 8 is rotatably connected to one end of the rocker arm 10. One end of the rocker arm 10 away from the second transmission rod 9 is rotatably connected to the rotating shaft 2. In this embodiment, the motor 6 drives the speed reducer 7 to work to drive the connecting rod component to transmit, so that the rotating shaft 2 rotates. The rotating shaft 2 and the rocker arm 10 make reciprocating motions within a range of 90 degrees.
[0034] As Figure 3 and Figure 4 shown, further, the second transmission rod 9 includes a first support rod 11 and a second support rod 12. A first sliding groove 13 and a first locking hole 14 are formed in the first support rod 11. A first locking bolt is arranged in the first locking hole 14. The second support rod 12 includes a second sliding groove 15 and a second locking hole 16. A second locking bolt is arranged in the second locking hole 16. The first locking bolt is located in the second sliding groove 15, and the second locking bolt is located in the first sliding groove 13. Therefore, the length of the second transmission rod 9 can be adjusted. The first support rod 11 and the second support rod 12 slide relative to each other to make the second transmission rod 9 extend or shorten. After the adjustment is completed, the first locking bolt and the second locking bolt are tightened to fix the relative locking between the first support rod 11 and the second support rod 12.
[0035] Further, the limiting mechanism includes a fixed rod 17. The fixed rod 17 is vertically and fixedly arranged on the frame 1. A limiting shaft 18 is fixedly arranged on the upper part of the fixed rod 17. A limiting plate 19 is rotatably arranged on the connecting rod 4. One end of the limiting plate 19 is rotatably connected to the connecting rod 4. A limiting groove 20 is formed in the limiting plate 19. The limiting shaft 18 is slidably arranged in the limiting groove 20. The limiting plate 19 and the limiting shaft 18 cooperate with each other to limit the tray 5, so that the tray 5 makes reciprocating motions between the vertical state and 90 degrees of the horizontal state. When the tray 5 is in the vertical state, the limiting plate 19 is in the horizontal state. On the contrary, when the tray 5 is in the horizontal state, the limiting plate 19 is in the vertical state.
[0036] Furthermore, a roller is rotatably arranged on the limiting shaft 18, and the roller is rollingly arranged in the limiting groove 20, which can reduce the friction between the limiting plate 19 and the roller and reduce wear.
[0037] Furthermore, the connecting rod 4 and the tray 5 are connected through a clamping seat 22. The clamping seat 22 is in a "Ji" - shaped structure. The bottom end of the clamping seat 22 is fixedly connected to the tray 5 by bolts, and the top of the clamping seat 22 is fixedly connected to the connecting rod 4.
