When the plastic bottle moves to the bottom of the air pressure leak detection cover, the limiter restricts the plastic bottle from moving forward, and the conveyor belt continues to move to transport the plastic bottle. When multiple plastic bottles gather under multiple air pressure leak detection covers, the control component controls motor one to turn off, so that multiple plastic bottles are aligned with multiple air pressure leak detection covers, which is convenient for starting cylinder one, so that the piston rod of cylinder one pushes the air pressure leak detection cover downward, so that the air pressure leak detection cover is covered on the bottle mouth of the plastic bottle.

[0010] By adopting the above technical solution, two guide rods 1 are set above the frame 1, and the distance between the two guide rods 1 is adjusted by moving the movable rod 1, so that the two guide rods can limit the plastic bottles of different sizes.

[0012] By adopting the above technical solution, motor one is started, so that the output shaft of motor one drives drive roller one to rotate, and drive roller one drives the conveyor belt to rotate and transport plastic bottles. At the same time, cylinder two is started, so that the piston rod of cylinder two drives limit rod one to move, and limit rod one moves to the top of the conveyor belt to limit the movement of the plastic bottle. When the plastic bottle moves to the bottom of the air pressure leak detection hood following the conveyor belt, the infrared sensor monitors the plastic bottle and transmits the monitoring signal to the control unit. When the control unit simultaneously receives the model of the plastic bottle detected by multiple infrared sensors, the control unit controls motor one to turn off and starts cylinder two, so that the piston rod of cylinder two drives limit rod one to move, and limit rod one moves to one side of the conveyor belt. Then cylinder one is started, so that the piston rod of cylinder one drives the air pressure leak detection hood to move downward to detect the sealing of the plastic bottle.

[0013] Preferably, a third cylinder is provided at one end of the top surface of the first frame, a push rod is fixed to the end surface of the piston rod of the third cylinder, the output ends of the plurality of pressure gauges are electrically connected to the input ends of the control unit, and the control end of the control unit is electrically connected to the control end of the third cylinder.

When the air pressure leak detection hood detects the sealing of the plastic bottle, the pressure gauge transmits the pressure signal value to the control unit. When the plastic bottle leaks, the pressure value of the pressure gauge cannot reach the highest peak value, indicating that the plastic bottle may be leaking. When the pressure signal value received by the control unit is less than the set pressure signal value, the control unit controls cylinder three to start, so that the piston rod of cylinder three pushes the push rod to move, so that the push rod pushes the leaking plastic bottle off the conveyor belt.

[0017] The transmission mechanism that this support rolls out is arranged on this support roll, and this support roll is located between this support roll and this support roll.

When the placement table is piled with enough plastic bottles for the packing box, the packing box is placed at one end of the packing table so that the front end of the packing box is in contact with the placement table, and then the pushing component is started to push the plastic bottles on the placement table into the packing box, thereby facilitating the packing of the plastic bottles with the packing box.

[0022] By adopting the above technical solution, the conveyor belt transports the plastic bottles to the packaging table, and the packaging boxes transported by the conveyor belt are counted by the counting sensor. The counted plastic bottles move to the position of limit rod 2, and limit rod 2 limits the forward movement of the plastic bottles. The counting sensor transmits the detected number of plastic bottles to the controller. When the counting sensor counts the number of plastic bottles in each row of the packaging box, the controller controls motor 3 to start, so that the output shaft of motor 3 drives limit rod 2 to rotate, so that limit rod 2 moves to one side of the conveyor belt, and a row of plastic bottles moves to one side of the push plate, so that when the push plate pushes the plastic bottles to the placement table, the number of plastic bottles in each row is the same.

[0023] Preferably, a connecting plate is fixed to the side of the placement table away from the frame 2, the bottom surface of the connecting plate is spaced apart from the top surface of the packing table, and guide plates are fixed on both sides of the top surface of the packing table.

When the plastic bottles follow the conveyor belt 34 to move to the position of the limit rod 62, the limit rod 62 blocks the plastic bottles from moving forward. When multiple infrared sensors 591 detect the plastic bottles at the same time, the multiple infrared sensors 591 transmit signals to the control unit 25, and the control unit 25 controls the motor 35 to turn off, so that the conveyor belt 34 stops moving, and then Then, multiple cylinders 21 are started at the same time, so that the piston rod of cylinder 21 drives the air pressure leak detection cover 22 to move downward, so that the air pressure leak detection cover 22 is placed on the bottle mouth of the plastic bottle, and then gas is transported to the air pressure leak detection cover 22 through the air pipe 23, so that the gas is input into the plastic bottle, and the air pressure on the pressure gauge 24 is observed at the same time. The pressure gauge 24 transmits the pressure signal to the control unit 25. When the pressure value on the pressure gauge 24 corresponding to a certain plastic bottle does not reach the pressure value set by the control unit 25, it indicates that the plastic bottle may have a leak, thereby completing the detection of the sealing of the plastic bottle. By performing sealing detection on multiple plastic bottles at the same time, the detection efficiency of the sealing of the plastic bottles is further improved. When the sealing test of the plastic bottle is completed, cylinder 2 61 is started, so that the piston rod of cylinder 2 61 drives limit rod 1 62 to move, so that limit rod 1 62 is separated from the plastic bottle. At the same time, the control unit 25 controls motor 1 35 to start, so that the conveyor belt 34 continues to convey the plastic bottle forward. When the leaking plastic bottle moves in front of the push rod 64, the control unit 25 controls cylinder 3 63 to start, so that the piston rod of cylinder 3 63 drives push rod 64 to move, so that push rod 64 pushes the leaking plastic bottle off the conveyor belt 34, causing the plastic bottle to hit the gauze 67 and fall into the receiving box 68, thereby facilitating the staff to collect and clean the leaking plastic products.

[0051] When the plastic bottles have completed the sealing test, the conveyor belt 34 conveys the plastic bottles to the conveyor belt 74 through the rotating roller 65, and the motor 2 75 is started. The output shaft of the motor 2 75 drives the conveyor belt 74 to rotate, so that the conveyor belt 74 conveys the plastic bottles forward. When the conveyor belt 74 conveys the plastic bottles, the conveyed plastic bottles are counted by the counting sensor. The plastic bottles passing the counting sensor move to the position of the limit rod 2 102, and the counting sensor transmits the counting signal to the controller. When the counting sensor counts the number of plastic bottles packaged in each row of the packaging box, the controller controls the motor 3 101 to start, so that the output shaft of the motor 3 101 drives the limit rod 2 102 to rotate, so that the limit rod 2 102 is separated from the plastic bottles, so that the conveyor belt 74 drives the plastic bottles forward. When the front plastic bottle moves to the position of the limit rack 103, the controller starts the motor 3 101 again, so that the output shaft of the motor 3 101 drives the limit rod 2 1 02 rotates to the top of the conveyor belt 74, so that the limit rod 2 102 blocks the subsequent plastic bottles, and then the cylinder 4 83 is started. The piston rod of the cylinder 4 83 drives the push plate 82 to move, so that the push plate 82 pushes the plastic bottles located above the packing table 8 to the placement table 81. When enough plastic bottles for packing boxes are gathered on the placement table 81, the packing box is placed between the two guide plates 89, and then the packing box is moved in the direction close to the placement table 81 so that the front end of the packing box is inserted between the gap between the connecting plate 88 and the packing table 8. Then the cylinder 5 86 is started, so that the piston rod of the cylinder 5 86 drives the push plate 87 to move downward, so that the push plate 87 moves to the bottle body position, and then the movable frame 85 is moved in the direction close to the packing box, so that the push plate 87 pushes the plastic bottles on the placement table 81 into the packing box. Then the staff takes out the packaging box and manually seals one side of the opening of the packaging box, thereby completing the packaging of the plastic bottles.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
