[0076] Cover-taking bin 2, connected to the lifting cover bin 1, used to pick up cup lids 3;

[0077] Lifting cover bin drive component 4, arranged in the lifting cover bin 1, used to drive the lifting cover bin lid support 15 in the lifting cover bin 1 to convey cup lids 3 to the cover-taking bin 2 under the action of the Kevlar rope 46;

[0078] Cover-taking bin drive component 5, arranged in the cover-taking bin 2, used to drive and control the opening and closing of the bin door 24 of the cover-taking bin 2, and at the same time drive the insect-proof cover link drive assembly 23 in the cover-taking bin 2 to control the opening and closing of the insect-proof cover 21.

[0079] Specifically, as Figure 2 shown, the lifting cover bin 1 includes a lifting cover bin guide post 11, a fixed column 12, a lifting cover bin sliding door 13, a rotary plunger 14, and a lifting cover bin lid support 15;

[0080] As Figure 2As shown, the lid-taking bin 2 for taking the cup lid 3 includes an insect-proof cover 21, a lid-taking bin housing 22, an insect-proof cover link driving assembly 23, and a bin door 24;

[0083] Specifically, a plurality of lifting lid-taking bin guiding columns 11 and fixed columns 12 are provided. The upper ends of the lifting lid-taking bin guiding columns 11 and the fixed columns 12 are both connected to the bottom of the lid-taking bin housing 22; the lower ends are both connected to the bottom of the lifting lid-taking bin 1, and the fixed column 12 is located on one side of the bottom of the lifting lid-taking bin 1 away from the lifting lid-taking bin sliding door 13.

[0084] In the specific implementation process, if two lifting lid-taking bin lid supports 15 are provided, four lifting lid-taking bin guiding columns 11 are provided, and the lifting lid-taking bin guiding columns 11 are located in the same vertical plane. The distance between two lifting lid-taking bin guiding columns 11 is greater than the diameter of the cup lid 3, so that the lifting lid-taking bin lid support 15 can be arranged between the two lifting lid-taking bin guiding columns 11. In this way, during the conveying and rising process, the lifting lid-taking bin guiding columns 11 can also play a role in restricting the rising path of the cup lid 3 to prevent it from tipping over.

[0085] In the specific implementation, the corresponding number of lifting lid-taking bin guiding columns 11 and fixed columns 12 can be set as needed. The present invention does not limit the number, and the lifting lid-taking bin guiding columns 11 and fixed columns 12 with other numbers or placement positions are all within the protection scope of the present invention.

[0086] Specifically, grooves are provided on the inner surface of the bottom of the lifting lid-taking bin 1 and the outer surface of the bottom of the lid-taking bin housing 22.

The diameter of the hollow part is the same as the diameter of the bottom guiding mechanism of the cup cover 3, and is used for positioning and placing the cup cover 3. A slider 6 is fixedly connected to the vertical handle of the lifting cover bin cover support 15, and the slider 6 can slide along the lifting cover bin linear guide rail 43 connected to the fixed column 12.

[0089] In a specific implementation, the diameter of the arc part of the water droplet shape of the lifting cover bin cover support 15 is larger than the diameter of the cup cover 3 to ensure that the cup cover 3 can be completely supported. An arc transition is adopted between the horizontal handle and the vertical handle of the lifting cover bin cover support 15 to increase the stress capacity of the lifting cover bin cover support 15 and extend the service life of the lifting cover bin cover support 15.

[0090] Specifically, the cover taking bin housing 22 is divided into two layers. The upper cover taking bin housing 22 is used to install the cover taking bin driving component 5.

[0092] In a specific implementation, two hollow square frames are provided on both sides of the bottom of the upper cover taking bin housing 22 close to the door 24. The length of the hollow square frame is greater than the length of the cover taking bin door output rocker 55, so that the cover taking bin driving rocker 53, the roller assembly 54, and the cover taking bin door output rocker 55 can swing freely in the hollow square frame.

[0093] Two circular hollow parts are provided at the place where the insect-proof cover 21 can cover on the bottom of the cover taking bin housing 22. The diameter of the circular hollow part is larger than the diameter of the cup cover 3, and is used to sequentially convey the cup cover 3 to the cover taking bin 2 by using the lifting cover bin cover support 15.

[0094] In a specific implementation, the number of the circular hollow parts can be designed as required. The design of other numbers of hollow parts or other shapes of hollow parts is within the protection scope of the present invention.

[0095] Specifically, the insect-proof cover 21 is connected to the bottom of the cover taking bin housing 22. The insect-proof cover 21 is in a half capsule shape. The width of the insect-proof cover 21 is larger than the diameter of the cup cover 3, and the length of the insect-proof cover 21 is larger than twice the diameter of the cup cover 3.

[0096] In a specific implementation, the width of the insect-proof cover 21 should be greater than the diameter of the cup lid 3.

The first rotating shaft 71 is used to drive the opening and closing of the insect-proof cover 21. One side of the first rotating shaft 71 is connected with an insect-proof cover link driving assembly 23. The other side of the insect-proof cover link driving assembly 23 is connected with the output rocker arm 55 of the lid-taking bin door. The insect-proof cover link driving assembly 23 is used to drive the rotation of the first rotating shaft 71 under the drive of the output rocker arm 55 of the lid-taking bin door to open and close the insect-proof cover 21.

[0098] In a specific implementation, the swinging of the output rocker arm 55 of the lid-taking bin door will drive the insect-proof cover link driving assembly 23 to work. The insect-proof cover link driving assembly 23 drives the first rotating shaft 71 to rotate. The rotating first rotating shaft 71 can drive the opening and closing movement of the insect-proof cover 21.

[0099] Specifically, the upper limit sensor 41 of the lifting lid bin is provided on the lid-taking bin housing 22. The number of the upper limit sensors 41 of the lifting lid bin is the same as that of the circular hollow parts, and they are located behind the circular hollow parts for detecting whether there is a cup lid 3 in the circular hollow parts.

[0100] The lower limit sensor 42 of the lifting lid bin is provided at the bottom of the lifting lid bin 1. The number of the lower limit sensors 42 of the lifting lid bin is the same as that of the lid supports 15 of the lifting lid bin for detecting whether there is a cup lid 3 at the bottom of the lifting lid bin 1 and for detecting whether the lid supports 15 of the lifting lid bin have descended to the specified positions.

[0101] Specifically, there are several linear guide rails 43 of the lifting lid bin. The number of the linear guide rails 43 of the lifting lid bin is the same as that of the lid supports 15 of the lifting lid bin. The linear guide rails 43 of the lifting lid bin can be slidably matched with the sliders 6 connected to the lid supports 15 of the lifting lid bin.

[0102] In a specific implementation, the centers of the hollow parts of the linear guide rails 43 of the lifting lid bin and their corresponding lid supports 15 of the lifting lid bin are located in the same vertical plane.

[0103] Specifically, the driving wire winding wheel 44 of the lifting lid bin is connected to the driving motor 45 of the lifting lid bin, and both are fixed on the fixed column 12. The number of the driving wire winding wheels 44 of the lifting lid bin and the driving motors 45 of the lifting lid bin is the same as that of the lid supports 15 of the lifting lid bin.

[0104] The Kevlar rope 46 bypasses the lifting cover bin driving winding wheel 44 and the slider 6. Under the drive of the Kevlar rope 46 and the lifting cover bin driving winding wheel 44, the slider 6 pulls the lifting cover bin cover support 15 to move the cup cover 3 upward.

[0105] In a specific implementation, the lifting cover bin driving winding wheel 44 and the lifting cover bin driving motor 45 are fixedly arranged at the upper half near the top of the fixed column 12 to rotate the lifting cover bin driving winding wheel 44, and the Kevlar rope 46 is used to pull the lifting cover bin cover support 15 towards the cover taking bin 2.

[0106] Specifically, the cover taking bin double-output shaft driving motor 51 is arranged at the edge of the upper layer cover taking bin housing 22.

[0107] Specifically, a roller assembly 54 is arranged on the side of the cover taking bin driving swing arm 53 far from the second rotating shaft 72. The cover taking bin driving swing arm 53 is connected to the cover taking bin door output swing arm 55 through the roller assembly 54. The swing of the cover taking bin driving swing arm 53 drives the roller assembly 54 to rotate, so as to drive the cover taking bin door output swing arm 55 to swing and open the bin door 24 of the cover taking bin 2.

[0108] In a specific implementation, the cover taking bin double-output shaft driving motor 51 starts to work, driving the second rotating shaft 72 to rotate. The second rotating shaft 72 drives the cover taking bin driving swing arm 53 to swing. The swinging cover taking bin driving swing arm 53 makes the roller assembly 54 start to roll to drive the connected cover taking bin door output swing arm 55 to swing. An insect-proof cover link driving assembly 23 is connected to the cover taking bin door output swing arm 55. When the cover taking bin door output swing arm 55 works, the connected insect-proof cover link driving assembly 23 will also start to work to realize the opening or closing of the insect-proof cover 21.
