At this time, the first nozzle 114 sprays disinfecting gas obliquely downward, and the disinfecting gas is injected into the disposable plastic cup whose cup mouth is in the same conveying direction as the conveyor belt 111, and pushes the disposable plastic cup to move along the arc-shaped groove on the supporting block 112, and then the folded edge of the disposable plastic cup is embedded in the fixed groove 113 on the supporting block 112, and the two adjacent supporting blocks 112 cooperate to restrict the disposable plastic cup from continuing to move, and the disinfecting gas sprayed by the first nozzle 114 can only be sprayed onto the outer wall of the disposable plastic cup whose cup mouth is facing the opposite conveying direction of the conveyor belt 111, and the disposable plastic cup is not affected, and the conveyor belt 111 continues to Continue to move the disposable plastic cup, the second nozzle 115 sprays disinfecting gas obliquely upward, and the folded edge of the disposable plastic cup with the cup mouth facing the same direction as the conveyor belt 111 is stuck in the fixed groove 113 on the supporting block 112, and the gas sprayed by the second nozzle 115 can only hit the outer wall of the disposable plastic cup, and the disposable plastic cup is not affected. The second nozzle 115 sprays disinfecting gas obliquely upward just enough to inject it into the disposable plastic cup with the cup mouth facing the opposite direction of the conveying direction of the conveyor belt 111, and gives the disposable plastic cup an oblique upward force, pushing the disposable plastic cup to flip over, so that the cup mouth of the disposable plastic cup is in the same direction as the conveying direction of the conveyor belt 111, and the conveyor belt 111 drives the disposable plastic cup to move, and the third nozzle 116 sprays disinfecting gas obliquely downward to disinfect the inner wall of the disposable plastic cup with the cup mouth facing the same direction as the conveying direction of the conveyor belt 111.

[0043] As another embodiment further provided by the present invention, a stacking cage 121 corresponding to the conveying channels formed by two adjacent conveyor belts 111 is disposed inside the stacking chamber 12 .

[0044] Specifically, the supporting blocks 112 on the conveyor belt 111 move the disposable plastic cups to the curved portion of the conveyor belt 111 , the gaps between the supporting blocks 112 increase, and the disposable plastic cups fall into the stacking cages 121 in the stacking chamber 12 under the action of gravity and are stacked in the stacking cages 121 .

[0049] Specifically, Figure 8 As shown, the bottom surface of the movable portion 123 occupies most of the bottom surface of the stacking cage 121. When the number of disposable plastic cups in the stacking cage 121 reaches a predetermined number, the limiting block 124 is tightly attached to the bottom surface of the fixed portion 122. At this time, the movable portion 123 rotates relative to the fixed portion 122, and the bottom surface of the movable portion 123 pushes the disposable plastic cups sleeved on the limiting block 124, so that the stacked disposable plastic cups are separated from the limiting block 124, and the stacked disposable plastic cups fall onto the movable portion 123. At this time, the stacked disposable plastic cups can be taken out and packaged.

At this time, the movable plate 125 drives the limit block 124 to move downward a predetermined distance. When the disposable plastic cup that falls into the stacking cage 121 is facing upward, the push rod 126 moves and pushes the disposable plastic cup out of the stacking cage 121. At this time, the movable plate 125 will not move downward, and the limit block 124 will not move, so that the next disposable plastic cup with the mouth facing downward can be stacked.

[0054] As another embodiment further provided by the present invention, a plurality of horizontal grooves 1251 are provided on the movable plate 125 , an inclined groove 1252 is provided between two adjacent horizontal grooves 1251 , and a tenon rod 128 adapted to the horizontal grooves 1251 and the inclined grooves 1252 is provided on the push rod 126 .

[0055] Specifically, a connecting rod 127 is slidably provided on the push rod 126, a tenon rod 128 is provided on the connecting rod 127, a spring is provided between the connecting rod 127 and the push rod 126, the push rod 126 is specifically a self-elastic telescopic rod, an elastic sheet 1253 is provided on the horizontal groove 1251 for blocking the adjacent upper inclined groove 1252, a connecting groove 1254 is provided between the uppermost horizontal groove 1251 and the lowermost horizontal groove 1251 on the movable plate 125, a blocking piece 1255 is hinged at the bottom of the connecting groove 1254, and a torsion spring is provided between the blocking piece 1255 and the movable plate 125.

[0056] Furthermore, during the reciprocating movement of the push rod 126, the tenon rod 128 moves along the horizontal groove 1251 on the movable plate 125. When the disposable plastic cups are normally stacked, the disposable plastic cups are stacked on the limit block 124 or the previous disposable plastic cup with their mouths facing downward. At this time, the push rod 126 will abut against the outer wall of the stacked disposable plastic cups during the reciprocating movement. At this time, the tenon rod 128 is facing the inclined groove 1252, and the elastic sheet 1253 abuts against the tenon rod 128. The movable plate 125 deforms the elastic sheet 1253 under the action of gravity, and the movable plate The inclined slot 1252 on 125 is opened, the movable plate 125 moves downward with the limit block 124, the limit block 124 moves downward with the disposable plastic cup, and gradually staggers with the push rod 126, and the tenon rod 128 enters the adjacent upper horizontal slot 1251 along the inclined slot 1252; when the disposable plastic cup dropped into the stacking cage 121 is facing upward, the push rod 126 moves quickly, and the tenon rod 128 passes quickly in the horizontal slot 1251 through the inclined slot 1252 blocked by the elastic sheet 1253 above, and the tenon rod 128 can move back and forth in the horizontal slot 1251.

[0057] Furthermore, the predetermined distance in the above embodiment is the distance between two adjacent horizontal grooves 1251, and the limit block 124 moves the predetermined distance to change the push rod 126 from abutting against the side wall of the normally stacked disposable plastic cups to abutting against the top of the normally stacked disposable plastic cups.

[0058] As another embodiment further provided by the present invention, a push block 131 for resisting the rotation of the movable part 123 is movably provided on the frame 1, and the limit block 124 moves to the lowest point to enable the push block 131 to move.

[0059] Specifically, a transmission wheel 117 is provided on the roller of the conveyor belt 111, a crankshaft 118 is rotatably provided on the frame 1, a synchronous chain is provided between the crankshaft 118 and the transmission wheel 117, a rocker 119 is provided between the crankshaft 118 and multiple push rods 126, a pull rope 129 is provided between the movable part 123 and the movable plate 125, a tenon block facing the movable plate 125 is provided on the push block 131, a groove adapted to the push block 131 is opened on the movable part 123, and a slope is provided on the side wall of the groove.

[0060] Furthermore, after the disposable plastic cup enters the disinfection chamber 11, the conveyor belt 111 drives the supporting block 112 to move, and the supporting block 112 pushes the disposable plastic cup so that the disposable plastic cup is located in the conveying channel formed between the two conveyor belts 111. At this time, the first nozzle 114 sprays disinfecting gas obliquely downward, and the disinfecting gas is injected into the disposable plastic cup whose cup mouth is in the same conveying direction as the conveyor belt 111, and pushes the disposable plastic cup to move along the arc-shaped groove on the supporting block 112, and then the folded edge of the disposable plastic cup is embedded in the fixed groove 113 on the supporting block 112, and the two adjacent supporting blocks 112 cooperate to restrict the disposable plastic cup from continuing to move, and the disinfecting gas sprayed by the first nozzle 114 can only be sprayed onto the outer wall of the disposable plastic cup whose cup mouth is facing the opposite conveying direction of the conveyor belt 111, and the disposable plastic cup is not affected. The conveyor belt 111 Continue to move the disposable plastic cup, the second nozzle 115 sprays disinfecting gas obliquely upward, the folded edge of the disposable plastic cup with the cup mouth facing the same direction as the conveyor belt 111 is stuck in the fixed groove 113 on the supporting block 112, and the gas sprayed by the second nozzle 115 can only hit the outer wall of the disposable plastic cup, and the disposable plastic cup is not affected. The second nozzle 115 sprays disinfecting gas obliquely upward just enough to inject it into the disposable plastic cup with the cup mouth facing the opposite direction of the conveying direction of the conveyor belt 111, and gives the disposable plastic cup an oblique upward force, pushing the disposable plastic cup to flip over, so that the cup mouth of the disposable plastic cup is in the same direction as the conveying direction of the conveyor belt 111, and the conveyor belt 111 drives the disposable plastic cup to move, and the third nozzle 116 sprays disinfecting gas obliquely downward to disinfect the inner wall of the disposable plastic cup with the cup mouth facing the same direction as the conveying direction of the conveyor belt 111.

[0061] The supporting blocks 112 on the conveyor belt 111 move the disposable plastic cup to the curved part of the conveyor belt 111, and the gaps between the supporting blocks 112 increase. The disposable plastic cup falls into the stacking cage 121 in the stacking cavity 12 under the action of gravity. When the disposable plastic cup with the cup mouth facing downward falls into the stacking cage 121, the cup mouth of the disposable plastic cup is buckled on the limiting block 124. The limiting block 124 cooperates with the stacking cage 121 to keep the disposable plastic cup in the center of the stacking cage 121, so as to support the disposable plastic cup that falls subsequently and stack multiple disposable plastic cups in the stacking cage 121.

[0062] When the conveyor belt 111 is working, the roller of the conveyor belt 111 drives the transmission wheel 117 to rotate, and the transmission wheel 117 drives the crankshaft 118 to rotate through the synchronous chain. The crankshaft 118 pushes the push rod 126 to reciprocate on the fixed part 122 of the corresponding stacking cage 121 through the rocker 119. During the reciprocating movement of the push rod 126, the tenon rod 128 moves along the horizontal groove 1251 on the movable plate 125. When the disposable plastic cups are stacked normally, the cup mouths of the disposable plastic cups face down and are stacked on the limit block 124 or the previous disposable plastic cup. At this time, the push rod 126 will abut against the outer wall of the stacked disposable plastic cups during the reciprocating movement. At this time, the tenon rod 128 is opposite to the inclined groove 1252, and the elastic sheet 1253 abuts against the tenon rod 128. The movable plate 125 deforms the elastic sheet 1253 under the action of gravity, and the inclined groove 1252 on the movable plate 125 opens. 125 moves downward with the limit block 124, and the limit block 124 moves downward with the disposable plastic cup, gradually staggered with the push rod 126, and the tenon rod 128 enters the adjacent upper horizontal groove 1251 along the inclined groove 1252; when the disposable plastic cup dropped into the stacking cage 121 has its mouth facing upward, it means that the inner wall of the disposable plastic cup has not been fully disinfected, and the bottom of the disposable plastic cup abuts against the bottom of the disposable plastic cup in the stacking cage 121, affecting the subsequent stacking of disposable plastic cups. At this time, the push rod 126 on the fixed part 122 moves, pushing the disposable plastic cup with the mouth facing upward to pass over the shorter movable part 123 and leave the stacking cage 121, and the push rod 126 moves rapidly, and the tenon rod 128 quickly passes through the inclined groove 1252 blocked by the elastic sheet 1253 above in the horizontal groove 1251, and the tenon rod 128 can move back and forth in the horizontal groove 1251.

[0063] After a certain amount of disposable plastic cups are stacked in the cage 121, the movable plate 125 moves to the lowest point, the limit block 124 is pressed against the bottom surface of the fixed portion 122, and the movable plate 125 moves along the inclined surface of the wedge block 132, pushing the wedge block 132 to move away from the movable portion 123. The wedge block 132 takes the push block 131 out of the groove at the bottom of the movable portion 123 and moves along the slope of the groove, pushing the bottom surface of the movable portion 123, and the movable portion 123 rotates. Since the bottom surface of the movable portion 123 occupies most of the bottom surface of the stacking cage 121, the movable portion 123 rotates during the rotation of the movable portion 123. The bottom surface of the movable part 123 pushes the disposable plastic cups on the limit block 124, so that the stacked disposable plastic cups are separated from the limit block 124, and the stacked disposable plastic cups fall onto the movable part 123. At this time, the stacked disposable plastic cups can be taken out and packaged, and the movable part 123 pulls the movable plate 125 upward through the pull rope 129, and the tenon rod 128 on the push rod 126 moves downward along the connecting groove 1254 on the movable plate 125, and pushes the blocking piece 1255 into the horizontal groove 1251 at the bottom of the movable plate 125, and the blocking piece 1255 seals the connecting groove 1254 again under the action of the torsion spring.

[0064] After the worker takes out the stacked disposable plastic cups, he manually pushes the movable part 123, and the slope on the movable part 123 pushes the push block 131 to move, so that the push block 131 returns to the groove at the bottom of the movable part 123, and the movable part 123 returns to the vertical state, and cooperates with the fixed part 122 to form a stacking cage 121, so as to continue to stack the disposable plastic cups.
