[0002] In the food, beverage, and daily chemical industries, plastic cups are a commonly used packaging container, and their demand continues to rise. The corresponding boxing process has become a critical link in the production flow. The boxing of plastic cups requires orderly handling, precise transfer, and standardized stacking, directly impacting product packaging efficiency and transportation safety.

[0017] 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.

[0018] Please see Figure 1-4 This embodiment discloses a plastic cup packing machine, which includes a frame 1, a track 2 above the frame 1, a slidable movable seat 3 on the track 2, a liftable connecting arm 4 inside the movable seat 3, a connecting seat 5 at the bottom of the connecting arm 4, three connecting frames 6 spaced apart on the connecting seat 5, a fixed frame 7 facing downward on the connecting frame 6, a set of vacuum suction cups 8 inserted downward on the bottom plate 71 of the fixed frame 7, each vacuum suction cup 8 including a connecting rod 81, the connecting rod 81 being limited and installed on the top surface of the bottom plate 71, the connecting rod 81 having a retaining ring 82, and a spring 83 located between the retaining ring 82 and the bottom plate 71 on the connecting rod 81, the connecting seat 5 having an inner cavity, a vacuum connector 9 communicating with the side wall of the connecting seat 5, and a connecting connector 10 communicating with each set of vacuum suction cups on the top surface of the connecting seat 5, the connecting connector 10 communicating with the corresponding vacuum suction cup 8 through a flexible hose.

[0019] In this device, the frame serves as the supporting foundation for the entire equipment. A track is fixedly installed on top of the frame, allowing the movable seat to slide smoothly along the track. The movable seat contains a liftable connecting arm, with a connecting seat at its bottom. The connecting seat has a hollow structure with an internal cavity. A vacuum connector is connected to the side wall of the connecting seat, and this vacuum connector is connected to an external vacuum pump (not shown in the figure) via a pipe. This connection provides negative pressure to the vacuum suction cups, allowing the negative pressure generated by the external vacuum pump to be transmitted to each vacuum suction cup through the vacuum connector, the internal cavity, the connecting connector, and the hose.

[0020] Figure 4 In this design, the vacuum suction cup 8 includes a connecting rod 81, with a limiting mounting sleeve 84 at its top. The limiting mounting sleeve 84 limits the connecting rod to the top surface of the base plate, preventing it from detaching. Simultaneously, when the vacuum suction cup grips the plastic cup, it moves upwards a small distance, compressing the spring. Under the cushioning effect of the spring, the vacuum suction cup tightly adheres to the top surface of the plastic cup, firmly adsorbing and fixing it in place.

[0021] Combination Figure 2-3The left and right fixed frames 7 are slidably installed on the connecting frame 6 at the same position, and the middle fixed frame is fixedly installed on the connecting frame at the same position. The left and right fixed frames are equipped with adjusting cylinders 11, and the drive shaft of the adjusting cylinder 11 is connected to the corresponding position of the connecting frame 6.

[0022] During the actual packing process, the distance between the three fixed frames can be adjusted by adjusting the extension and retraction of the cylinder to drive the fixed frames on the left and right sides to slide on the connecting frame in the same position, according to the specifications of the plastic cups to be packed and the packing arrangement requirements.

[0023] As a preferred structure, combined with Figure 2 , Figure 5 The connecting arm 4 is slidably installed inside the movable seat 3. A lifting belt 12 is fixed on the side wall of the connecting arm 4. An upper pressure wheel 13, a lower pressure wheel 14, and a lifting wheel 15 are rotatably installed inside the movable seat 3. The lifting belt 12 passes around the upper pressure wheel 13, the lifting wheel 15, and the lower pressure wheel 14 in sequence. The upper pressure wheel 13 and the lower pressure wheel 14 press against the outer surface of the lifting belt 12, and the lifting wheel 15 presses against the inner surface of the lifting belt 12. The rotating shaft of the lifting wheel 15 passes through the movable seat 3 and is connected to a rotating wheel 16. The movable seat 3 is provided with a lifting motor 17 for driving the rotating wheel to rotate.

[0024] In this structure, a lifting belt is fixed to the side wall of the connecting arm. The lifting belt passes sequentially around the upper pressure wheel, the lifting wheel, and the lower pressure wheel. The upper and lower pressure wheels press against the outer surface of the lifting belt, while the lifting wheel presses against the inner surface of the lifting belt, forming a stable transmission structure. When the lifting motor is working, it drives the rotating wheel and the lifting wheel to rotate, which in turn drives the connecting arm to move up and down via the lifting belt.

[0025] As a specific structure, Figure 2 In the track 2, a driving wheel 18 and a driven wheel 19 are rotatably mounted on the side walls, respectively. A sliding belt 20 is provided between the driving wheel 18 and the driven wheel 19, and a belt connecting block 21 is provided on the sliding belt 20. The belt connecting block 21 is connected to the movable seat 3. A sliding motor 22 for driving the driving wheel to rotate is also provided on the track 2. When the sliding motor is working, it drives the driving wheel to rotate, which in turn drives the movable seat to slide along the track via the sliding belt.

[0026] The working principle of the above embodiment is as follows: First, according to the specifications of the plastic cups to be packed and the packing arrangement requirements, the adjusting cylinders in the left and right fixed frames are controlled to extend and retract, driving the left and right fixed frames to slide along the connecting frame, adjusting the distance between the three fixed frames, and then closing the adjusting cylinders after the adjustment is completed.

[0027] Start the sliding motor, which drives the drive wheel to rotate. This drives the moving seat to slide along the track to the top of the plastic cup conveyor line via the sliding belt and belt connecting block. Then, start the lifting motor, which drives the lifting wheel to rotate. This drives the connecting arm to descend via the lifting belt, bringing the vacuum suction cup on the fixing frame into contact with the top surface of the plastic cup. With the cushioning effect of the spring, the vacuum suction cup tightly adheres to the top surface of the plastic cup, adsorbing and fixing the plastic cup in place.

[0028] The lifting motor reverses, raising the connecting arm to the set height. Then, the sliding motor reverses again, moving the moving seat along the track to above the packaging box. The lifting motor then rotates forward again, lowering the connecting arm so that the plastic cup falls into the set position inside the packaging box. The external vacuum pump is then turned off, and the vacuum suction cup loses its suction force, separating from the plastic cup. Finally, the lifting motor reverses again, raising the connecting arm back to its original position, completing one packing operation.

[0029] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
