[0021] The fixed plate 7 is evenly fixed with guide rods 701, and a leakage hole 702 is provided on the fixed plate 7, and the leakage hole 702 is equal in size to the circular hole 502, and four guide rods 701 are distributed around the leakage hole 702; the lower end surface of the fixed plate 7 is symmetrically fixed with a side plate 8, and the side plate 8 is located above the conveyor belt 4; the side plate 8 is symmetrically fixed with a first cylinder 9, and an upper clamping plate 901 is fixed at the output end of the first cylinder 9, and an arc groove corresponding to the position of the leakage hole 702 is provided on the upper clamping plate 901; the side plate 8 is symmetrically fixed with a second cylinder 10, and a lower clamping plate 1001 is fixed at the output end of the second cylinder 10, and an arc groove corresponding to the position of the leakage hole 702 is provided on the lower clamping plate 1001;

[0022] When using the automatic cup lid dropping device, if Figure 1-Figure 5As shown, firstly, the whole device is installed and powered by an external power supply, and then the stacked cup covers are placed between the guide rods 701, and the cup covers can slide downward through the leakage holes 702, and then the first cylinder 9 is started to extend, and the upper clamping plate 901 is driven to move by the first cylinder 9, thereby reducing the distance between the two upper clamping plates 901, so that the upper clamping plate 901 can clamp and fix the flange on the lowermost cup cover, thereby ensuring the stability of the stacked cup covers and the bottom surface of the lowermost cup cover in the stack is just flush with the lower end surface of the lower clamping plate 1001, thereby achieving the installation of the cup covers;

[0023] The support bracket 5 is evenly provided with support holes 501, and the support bracket 5 is also evenly provided with round holes 502, and the diameter of the round holes 502 is smaller than the diameter of the support holes 501, and the round holes 502 and the through holes 401 are distributed in a one-to-one correspondence, and the diameter of the round holes 502 is equal to the diameter of the through holes 401; a movable plate 1201 is fixed to the output end of the third cylinder 12, and vertical rods 1202 are evenly fixed to the movable plate 1201, and a suction cup 1203 is fixed to the upper end of the vertical rod 1202; the diameter of the suction cup 1203 is smaller than the diameter of the through hole 401, and the positions of the suction cup 1203 and the leakage hole 702 correspond to each other;

[0024] In actual use, the conveyor belt 4 and the supporting frame 5 are moved by the roller 3. When the supporting hole 501 on the supporting frame 5 moves to just below the leakage hole 702, the second cylinder 10 extends to drive the lower clamping plate 1001 to move and adjust the distance between the two clamping plates 1001. After the adjustment is completed, the maximum distance between the grooves on the lower clamping plate 1001 is greater than the lower diameter of the cup cover, and the maximum distance between the grooves on the lower clamping plate 1001 is less than the diameter of the upper flange of the cup cover. The cylinder 9 is then controlled to contract and drive the upper clamping plate 901 to move, thereby releasing the limit on the stacked cup covers. The stacked cup covers slide downward under the action of gravity until the upper flange of the lowermost cup cover contacts the upper end surface of the lower clamping plate 1001. At this time, the upper flange of the second-to-last cup cover on the lower side of the stacked cup covers is just located between the upper clamping plates 901. The cylinder 9 is then started to extend and drive the upper clamping plate 901 to move to clamp and limit the upper flange of the second-to-last cup cover, and the cylinder is started The third cylinder 12 extends, thereby driving the movable plate 1201, the vertical rod 1202 and the suction cup 1203 to move upward, so that the suction cup 1203 passes through the through hole 401 and the circular hole 502 and contacts the lowermost cup cover, thereby realizing the adsorption effect of the cup cover, and then controlling the second cylinder 10 to contract and drive the lower clamping plate 1001 to move, which can release the limiting effect of the lowermost cup cover, and controlling the third cylinder 12 to contract and drive the movable plate 1201, the vertical rod 1202, the suction cup 1203 and the cup cover to move downward. When the cup cover cooperates with the supporting hole 501, the third cylinder 12 continues to contract to separate the suction cup 1203 from the cup cover, thereby realizing the automatic and accurate falling effect of the cup cover. According to the above principle, by controlling the roller 3 to drive the conveyor belt 4 to operate, each movement makes the position of the next support bracket 5 just move to the position of the previous support bracket 5, thereby realizing the continuous automatic cover falling effect. This is the working principle of the automatic cover falling device for the cup cover.
