[0002] Paper cups are lightweight containers made of pulp or cardboard, usually with a waterproof coating on the inside, primarily used for holding hot and cold beverages. They are characterized by their single-use nature, portability, and low cost, and are widely used in fast food restaurants, offices, and outdoor activities. Modern paper cups are mostly conical or cylindrical in shape, and some are printed with brand logos or environmental reminders. They are recyclable but require sorting and disposal as everyday consumables.

[0003] During the paper cup production process, brand logos or environmental protection notices are printed on the surface. Traditional printing equipment lacks the function of precise printing positioning. During production, paper cups are transported by conveyor belts, and printing is performed by pausing the conveyor belt. Therefore, the printing position is prone to significant deviation, affecting the production pass rate of paper cups. Utility Model Content

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figures 1-5 As shown, this utility model provides a technical solution: a paper cup printing pattern precision positioning mechanism, including a pattern printing device body 11, and further comprising:

[0027] The base 1 and the main body 11 of the pattern printing device are fixedly installed on the top of the base 1;

[0028] Precision guiding mechanism 2 is located on the top of base 1 and is used to guide unprinted paper cups.

[0029] The precision gripping mechanism 3 is located on the top of the base 1 and is used to grip and move the paper cup.

[0030] Receiving mechanism 4 is located on top of base 1 and is used to guide the printed paper cups.

[0031] The precision guiding mechanism 2 includes a connecting frame 21, a strip frame 22 fixedly installed on the right side of the connecting frame 21, the strip frame 22 fixedly installed on the top of the base 1, and limit bars 23 fixedly installed on the front and back of the inner wall of the strip frame 22. A roller shaft 24 is rotatably connected between the front and back of the inner wall of the strip frame 22. The connecting frame 21 is used to guide the paper cups on the conveyor belt into the inner cavity of the strip frame 22. The paper cups will slide and move on the top of the roller shaft 24. At the same time, the design of the limit bars 23 can limit the side wings of the paper cups to ensure the accuracy of the paper cups' movement position. Furthermore, the design of the precision gripping mechanism 3 can grip and move the paper cups to facilitate the precise printing process of the paper cups in conjunction with the main body 11 of the pattern printing device.

[0032] As one implementation method in this embodiment, such as Figure 3 As shown, the precision gripping mechanism 3 includes a first support arm 31 and a second support arm 32. The first support arm 31 is fixedly installed on the top of the base 1, and the second support arm 32 is fixedly installed on the top of the base 1. A servo motor 33 is fixedly installed on the side of the first support arm 31. A lead screw 34 is rotatably connected between adjacent sides of the first support arm 31 and the second support arm 32. A track rod 35 is fixedly installed between adjacent sides of the first support arm 31 and the second support arm 32. The output shaft of the servo motor 33 is fixedly connected to the end of the lead screw 34. A sliding seat 36 is slidably connected to the outer wall of the lead screw 34 and the track rod 35. Controlling the servo motor 33 to work can drive the lead screw 34 to rotate, thereby causing the sliding seat 36 to slide left and right on the outer wall of the track rod 35, so as to facilitate the movement control of the gripped paper cup.

[0033] As one implementation method in this embodiment, such as Figure 3 As shown, a connecting platform 37 is fixedly installed on the front of the sliding seat 36, and a first electric cylinder 38 is fixedly installed on the top of the connecting platform 37. The telescopic end of the first electric cylinder 38 extends to the bottom of the connecting platform 37 and a frame 39 is fixedly installed thereon. By controlling the telescopic operation of the first electric cylinder 38, the height of the frame 39 can be adjusted to facilitate the paper cup gripping action.

[0034] As one implementation method in this embodiment, such as Figure 4As shown, an air pump 391 is fixedly installed on the top of the inner wall of the frame 39, a tee 392 is fixedly connected to the bottom of the inner wall of the frame 39, an electric valve 393 is fixedly connected to the outer wall of the tee 392, the output end of the air pump 391 is fixedly connected to the top of the tee 392, a round tube 394 is fixedly connected to the bottom of the frame 39, an annular airbag 395 is fixedly connected to the outer wall of the round tube 394, the inner cavity of the tee 392 communicates with the inner cavity of the round tube 394, and a small hole is opened on the outer surface of the round tube 394, so that the round tube 391... The inner cavity of tube 4 is connected to the inner cavity of the annular airbag 395. After the entire round tube 394 extends into the paper cup, the air pump 391 is controlled to work, which can deliver gas into the inner cavity of the three-way valve 392. The gas then enters the interior of the annular airbag 395, causing the annular airbag 395 to expand and elastically deform, thereby securing the paper cup to its outer surface. If it is necessary to release the paper cup, the electric valve 393 is controlled to open, releasing the gas inside the annular airbag 395, allowing the annular airbag 395 to recover its deformation, thus completing the release of the paper cup.

[0035] As one implementation method in this embodiment, such as Figure 5 As shown, the receiving mechanism 4 includes a receiving frame 41 and a second electric cylinder 43. An output roller 42 is rotatably connected between the front and back sides of the inner wall of the receiving frame 41. The tilt angle of the receiving frame 41 is 5°. Through the cooperation of the receiving frame 41 and the output roller 42, the printed paper cups can be received. Since its overall tilt design, the paper cups can be guided.

[0036] As one implementation method in this embodiment, such as Figure 5 As shown, the second electric cylinder 43 is fixedly installed on the top of the base 1. The telescopic end of the second electric cylinder 43 is fixedly connected to the outer wall of the receiving frame 41. A slider 45 is fixedly installed on the outer wall of the receiving frame 41. A vertical rod 44 is slidably connected to the inner wall of the slider 45. The vertical rod 44 is fixedly installed on the top of the base 1. Before receiving the paper cup, the second electric cylinder 43 is controlled to extend, which can raise the overall height of the receiving frame 41 and the output roller 42, reduce the drop of the paper cup, and ensure the safety of the paper cup. After receiving the paper cup, the second electric cylinder 43 is controlled to retract, reducing the drop at the output end. The slider 45 can slide on the outer wall of the vertical rod 44 as the receiving frame 41 rises and falls, increasing stability.

[0037] Working principle: In use, the paper cup conveyor belt is set up at the left end of the connecting frame 21 and the right end of the receiving frame 41. The connecting frame 21 guides the paper cups on the conveyor belt into the inner cavity of the strip frame 22. The paper cups slide on the top of the roller 24. At the same time, the design of the limiting bar 23 can limit the side wings of the paper cups to ensure the accuracy of the paper cup movement position. Then, the first electric cylinder 38 is controlled to extend, so that the round tube 394 extends into the inside of the paper cup. Then, the air pump 391 is controlled to work, which can deliver gas into the inner cavity of the three-way valve 392. The gas then enters the interior of the annular air bladder 395, causing the annular air bladder 395 to expand elastically. The first electric cylinder 38 is then retracted to raise the height of the paper cup. The servo motor 33 is then activated, causing the paper cup to move to the right and pause near the main body 11 of the pattern printing device for printing. After printing, the servo motor 33 is activated again, moving the fixed paper cup to the top of the receiving frame 41. The electric valve 393 is then opened to release the gas inside the annular airbag 395, allowing the annular airbag 395 to recover its deformation and release the paper cup. The receiving frame 41 and the guide roller 42 then work together to receive the printed paper cup and guide it to the subsequent conveyor belt.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
