The connecting plate is fixedly connected to the slider. The fixed end of the vertical drive cylinder is fixedly connected to the connecting plate. The suction cup 8 is connected to the movable end of the vertical drive cylinder.

[0030] Storage tray 6, used to hold plastic cups and bowls;

[0031] The propulsion mechanism is located on the storage tray 6 and is used to stack plastic cups and bowls.

[0032] The storage tray 6 has multiple positioning holes 5 arranged in a rectangular array. Each positioning hole 5 is detachably fitted with a storage tube 7, which is used to hold plastic cups and bowls.

[0033] Both ends of the storage cylinder 7 are open, and the bottom end of the storage cylinder 7 is equipped with an openable end cap. Specifically, the top of the storage cylinder 7 has lugs on both sides, and each positioning hole 5 has an ear groove. The lugs and ear grooves match. When the storage cylinder 7 is inserted into the positioning hole 5, the lugs and ear grooves are aligned and inserted, thus completing the positioning of the storage cylinder 7. The end cap can be connected to the bottom end of the storage cylinder 7 by existing hinges, and the other side of the end cap can be equipped with a buckle to close the storage cylinder 7.

[0034] The storage tray 6 is connected to two sides by transmission chains 4, each transmission chain 4 is wound around two gear disks 3, one of which is connected to a drive motor 2. Specifically, the storage tray 6 is a flat plate structure, and the two ends of the storage tray 6 can be connected to the transmission chains 4 by screws. The gear disks 3 that are not connected to the drive motor 2 are rotatably connected to the base frame 1 through a rotating shaft and bearings. The base frame 1 is composed of two rectangular frames spaced apart.

[0035] The propulsion mechanism includes a fixed bracket 11, a drive component 12, and a pressure plate 13. The fixed bracket 11 is fixed to the outside of the storage tray 6, the drive component 12 is mounted on the fixed bracket 11, and the pressure plate 13 is connected to the drive component 12. The pressure plate 13 is provided with pressure rods 14, the number of pressure rods 14 corresponds to the number of positioning holes 5, and each pressure rod 14 faces the center of a positioning hole 5.

[0036] The fixed support 11 includes a left support and a right support, which are respectively set on both sides of the storage tray 6; the driving component 12 includes a crossbeam and a driving cylinder, with the two ends of the crossbeam respectively mounted on the left and right supports, the driving cylinder set on the crossbeam, and the pressure plate 13 fixed to the movable end of the driving cylinder. Specifically, the left and right supports are each equipped with a horizontal moving component 10, that is, there are two sets of horizontal moving components 10 for the handling robot, and the two sets of horizontal moving components 10 are respectively fixed on the left and right supports; the driving cylinder is threadedly connected to the horizontal moving component 10 through the crossbeam, and the horizontal moving component 10 drives the driving cylinder to move, and the driving cylinder drives the pressure plate 13 to rise and fall in the vertical direction, so that the pressure rod 14 can move towards the positioning hole 5, pushing the plastic cups and bowls into the storage cylinder 7 for stacking.

[0037] The pressure rod 14 is a telescopic rod structure. Specifically, the pressure rod 14 includes a fixed cylinder, a movable rod, and a spring. One end of the fixed cylinder is fixed to the bottom of the pressure plate 13, and the other end of the fixed cylinder has a movable opening. The movable rod is inserted into the fixed cylinder through the movable opening. A spring connects the movable rod and the fixed cylinder. A limiting groove is provided on the side wall of the fixed cylinder, and a limiting block is provided on the movable rod. The limiting block is slidably connected to the limiting groove. By setting the pressure rod 14 as described above, during the pressing process of the pressure plate 13, the movable rod first contacts the plastic cup and bowl and squeezes the plastic cup and bowl, causing the plastic cup and bowl to move into the storage cylinder 7. Due to the reaction force of the plastic cup and bowl, the movable rod moves in the opposite direction. Through the cooperation of the spring and the limiting groove and the limiting block, the rigid contact between the movable rod and the plastic cup and bowl can be reduced, which could cause damage to the plastic cup and bowl or result in uneven stacking.

[0038] In use, the horizontal moving component 10 drives the vertical moving component 9 and the suction cup 8 to move horizontally. When the suction cup 8 moves above the mold of the plastic cup and bowl processing equipment, the horizontal moving component 10 stops driving, and the vertical moving component 9 starts, driving the suction cup 8 to move towards the mold until the suction cup 8 adsorbs the plastic cup and bowl on the mold. Then, the vertical moving component 9 drives the suction cup 8 to rise away from the mold and reset. The horizontal moving component 10 drives the suction cup 8 to move towards the storage tray 6 until the suction cup 8 is aligned with the storage tray 6. The vertical moving component 9 drives the suction cup 8 to move towards the storage tray 6. After moving into position, the suction cup 8 stops the negative pressure adsorption, and the plastic cup and bowl is placed in the storage cylinder 7 at the positioning hole 5. The vertical moving component 9 drives the suction cup 8 to reset, and the horizontal moving component 10 drives the suction cup 8 to move... During the transport of the next set of plastic cups and bowls, the horizontal moving component 10 moves, and the pushing mechanism also moves accordingly. Therefore, when the horizontal moving component 10 moves the suction cup 8 above the mold, the pressure plate 13 is located above the storage tray 6. The driving component 12 drives the pressure plate 13 to move towards the storage tray 6. The pressure rod 14 of the pressure plate 13 pushes the plastic cups and bowls into the storage cylinder 7, completing the stacking of a set of plastic cups and bowls. The above process is repeated to stack the plastic cups and bowls into the storage cylinder 7. When the storage cylinder 7 is full of stacked plastic cups and bowls, the drive chain 4 is driven by the drive motor 2 to move the drive chain 4, and another storage tray 6 is installed on the drive chain 4. The storage cylinder 7 is taken out from the storage tray 6, the end cap is opened, and a cylinder of plastic cups and bowls is taken out and placed in a packaging bag.
