[0012] Operating method of the device: Step 1: Feeding. The first vacuum chamber and the second vacuum chamber can be evacuated to a vacuum state by a vacuum pump, and the vacuum degree inside can be observed through a vacuum pressure display. The product packaging bottle to be tested is conveyed to the bottom of the detection box through a group of first conveyor belts. Step 2: Fixing. The detection box can be lowered by the second electric push rod until the suction cup abuts against the top of the product packaging bottle. At this time, the spring can be compressed by the suction cup, and under the action of the spring, the bottom end of the suction cup is tightly attached to the top of the product packaging bottle. Then the first three-way solenoid valve and the first solenoid valve work. At this time, the air between the suction cup and the product packaging bottle enters the first vacuum chamber through the fourth connecting pipe, the second connecting pipe, and the first connecting pipe. Under the action of the external atmospheric pressure, the product packaging bottle is sucked by the suction cup. Step 3: Transferring. The detection box is lifted by the second electric push rod, and the product packaging bottle can be lifted by the suction cup. The product packaging bottle is moved to the top of the bottom plate through the moving plate, the second electric push rod, the detection box, and the suction cup. The detection box and the product packaging bottle are lowered by the second electric push rod so that the product packaging bottles are respectively located on the top of the pressure sensors. The first three-way solenoid valve is made to work again, allowing external air to enter the first connecting pipe, and at the same time closing the first connecting pipe at one end of the first vacuum chamber. At this time, the suction cup no longer tightly sucks the product packaging bottle. Step 4: Detection. The product packaging bottle inside the detection chamber can be detected through the pressure sensor. At this time, the second three-way solenoid valve works, and at the same time, the second solenoid valve in the detection chamber with the product packaging bottle also works. The seventh connecting pipe is opened through the second three-way solenoid valve, and the sixth connecting pipe is opened through the second solenoid valve. At this time, the air pressure inside the detection chamber can be instantaneously reduced through the second three-way solenoid valve, the seventh connecting pipe, the fifth connecting pipe, the sixth connecting pipe, and the second solenoid valve. Then the second three-way solenoid valve and the second solenoid valve are instantaneously closed. The air pressure change inside the detection chamber is detected through the air pressure detection sensor. If the air pressure inside the detection chamber changes, the corresponding product packaging bottle inside the detection chamber is a product with unqualified sealing, otherwise it is a qualified product. After the detection is completed, one end of the seventh connecting pipe is connected to the outside air through the second three-way solenoid valve, and the inside of the detection chamber is made to be the same as the outside atmospheric pressure by opening the second solenoid valve; Step 5: Transfer again. The suction cup tightly sucks the product packaging bottle again through the first three-way solenoid valve and the first solenoid valve. The detection box and the product packaging bottle are moved to the first conveyor belt on one side of the second conveyor belt through the second electric push rod and the first electric push rod. Then the detection box is reset through the first electric push rod and the second electric push rod, and the next group of product packaging bottles is detected again; Step 6: Remove the unqualified product packaging bottle. The third electric push rod corresponding to the unqualified product packaging bottle for detection works. The fixed sleeve and the semi-circular sleeve plate are moved to one side of the product packaging bottle through the third electric push rod. Then the double-shaft motor works, and the arc-shaped buckle plate is moved through the gear and the tooth groove until one side of the limit block fits against the inner wall at one end of the limit arc groove. At this time, the movement stops. The fixed sleeve, the semi-circular sleeve plate, and the product packaging bottle can be moved through the third electric push rod until the product packaging bottle is at the top of the second conveyor belt. Then the arc-shaped buckle plate is reset through the double-shaft motor and the gear. Finally, the fixed sleeve and the semi-circular sleeve plate are reset again through the third electric push rod. At the same time, it can be detected through the third electric push rod whether all the unqualified product packaging bottles are at the top of the second conveyor belt. If there are unqualified product packaging bottles at the top of the first conveyor belt, the second conveyor belt will not start at this time, otherwise the second conveyor belt starts and moves away the unqualified product packaging bottles.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The first vacuum chamber and the second vacuum chamber can be evacuated to a vacuum state by a vacuum pump. The vacuum pressure display can be used to observe the vacuum degree inside. After the product packaging bottle of the sample to be tested is conveyed to the bottom of the detection box by a set of first conveyor belts, the detection box can be lowered by the second electric push rod at this time, so that the product packaging bottle is inside the detection chamber until the suction cup touches the top of the product packaging bottle. At this time, the suction cup can compress the spring, and under the action of the spring, the bottom end of the suction cup is tightly attached to the top of the product packaging bottle. Then the first three-way solenoid valve and the first solenoid valve work. At this time, the air between the suction cup and the product packaging bottle enters the inside of the first vacuum chamber through the fourth connecting pipe, the second connecting pipe and the first connecting pipe. Under the action of the external atmospheric pressure, the product packaging bottle is sucked by the suction cup. The detection box is lifted by the second electric push rod until the bottom end of the limit ring fits with the inner wall of the bottom end of the limit groove. At this time, the product packaging bottle can be lifted by the suction cup. Then the moving plate slides on the surface of the sliding rod by the first electric push rod. The product packaging bottle is moved to the top of the bottom plate through the moving plate, the second electric push rod, the detection box and the suction cup. The detection box and the product packaging bottle are lowered by the second electric push rod so that the product packaging bottles are respectively on the top of the pressure sensors. At this time, the first three-way solenoid valve works again to make the external air enter the first connecting pipe, and at the same time, the first connecting pipe at one end of the first vacuum chamber is closed. At this time, the suction cup no longer tightly sucks the product packaging bottle. The product packaging bottle inside the detection chamber can be detected by the pressure sensor. At this time, the second three-way solenoid valve works, and at the same time, the second solenoid valve with the product packaging bottle inside the detection chamber also works. The seventh connecting pipe is opened by the second three-way solenoid valve, and the sixth connecting pipe is opened by the second solenoid valve. At this time, the air pressure inside the detection chamber can be instantly reduced through the second three-way solenoid valve, the seventh connecting pipe, the fifth connecting pipe, the sixth connecting pipe and the second solenoid valve. Then the second three-way solenoid valve and the second solenoid valve are instantly closed. The air pressure change inside the detection chamber is detected by the air pressure detection sensor. If the air pressure inside the detection chamber changes, the product packaging bottle inside the corresponding detection chamber is a product with unqualified sealing, otherwise it is a qualified product. After the detection is completed, one end of the seventh connecting pipe is connected to the external air by the second three-way solenoid valve. The inside of the detection chamber is made to be the same as the external atmospheric pressure by opening the second solenoid valve, which is convenient for the second electric push rod to drive the detection box to move up. At the same time, the suction cup tightly sucks the product packaging bottle again through the first three-way solenoid valve and the first solenoid valve. The detection box and the product packaging bottle are moved to the first conveyor belt on one side of the second conveyor belt by the second electric push rod and the first electric push rod. Then the detection box is reset by the first electric push rod and the second electric push rod, and the next group of product packaging bottles are detected again. At the same time, the third electric push rod corresponding to the product packaging bottle with unqualified detection works. The fixed sleeve and the semi-circular sleeve plate are moved to one side of the product packaging bottle by the third electric push rod. Then the double-shaft motor works, and the arc-shaped buckle plate is moved through the gear and the tooth groove.The arc-shaped chute and arc-shaped slide plate can guide the arc-shaped buckle plate. The limit arc groove and the limit block can limit the moving distance of the arc-shaped buckle plate. After the arc-shaped buckle plate drives the limit block until one side of the limit block fits against the inner wall of one end of the limit arc groove, the movement stops at this time. The third electric push rod can move the fixed sleeve, the semi-circular sleeve plate and the product packaging bottle until the product packaging bottle is at the top of the second conveyor belt. Then, the arc-shaped buckle plate is reset by the double-shaft motor and the gear. Finally, the fixed sleeve and the semi-circular sleeve plate are reset by the third electric push rod again. At the same time, it can be detected by the third electric push rod whether all unqualified product packaging bottles are at the top of the second conveyor belt. If there are unqualified product packaging bottles at the top of the first conveyor belt, the second conveyor belt will not start at this time. Otherwise, the second conveyor belt starts to move the unqualified product packaging bottles away. This device can complete the detection work automatically, and can also separately take out and move away the unqualified product packaging bottles, which further facilitates the user's detection work. This device is simple and convenient to operate, does not require multiple people to operate, further reduces the practical cost. At the same time, this device detects by means of negative pressure, and judges the sealing performance according to the change of pressure, which will not cause any pollution or damage to the product packaging bottle, and can also improve the detection accuracy. At the same time, it can further reduce the user's usage cost and maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

After the arc-shaped clamping plate 45 drives the limiting block 49 until one side of the limiting block 49 fits against the inner wall of one end of the limiting arc groove 48, the movement stops at this time. The fixed sleeve 43, the semi-circular sleeve plate 44 and the product packaging bottle 11 can be moved through the third electric push rod 42 until the product packaging bottle 11 is at the top of the second conveyor belt 5. Then the arc-shaped clamping plate 45 is reset through the double-shaft motor 51 and the gear 52. Finally, the fixed sleeve 43 and the semi-circular sleeve plate 44 are reset again through the third electric push rod 42. At the same time, it can be detected through the third electric push rod 42 whether all unqualified product packaging bottles 11 are at the top of the second conveyor belt 5, and a ring can be formed to facilitate the limitation and movement of the product packaging bottle 11; Please refer to Figures 3 - 6, in this embodiment, the detection mechanism includes a fifth connecting pipe 31, a sixth connecting pipe 32, a second solenoid valve 33, a seventh connecting pipe 34, a second three-way solenoid valve 35, a bottom plate 36, an installation groove 37, a pressure sensor 38, and an air pressure detection sensor 39.

One end of the fifth connecting pipe 31 is connected to a seventh connecting pipe 34, and one end of the seventh connecting pipe 34 passes through the pipe groove 29 and is connected to the second vacuum chamber 13. A second three-way solenoid valve 35 is provided at one end of the seventh connecting pipe 34. The tops of the detection chambers 19 are all connected to a sixth connecting pipe 32, and the tops of the sixth connecting pipes 32 are all connected to the fifth connecting pipe 31. Second solenoid valves 33 are provided in the middle of the sixth connecting pipes 32. The middle of the workbench 1 is fixedly connected to a bottom plate 36. Installation grooves 37 are evenly formed in the top of the bottom plate 36. Pressure sensors 38 are provided inside the installation grooves 37, and the positions of the pressure sensors 38 respectively correspond to the detection chambers 19. Air pressure detection sensors 39 are provided at both ends of the pressure sensors 38. The control ends of the second solenoid valve 33, the second three-way solenoid valve 35, the pressure sensor 38, and the air pressure detection sensor 39 are all electrically connected to the control panel 2. The bottom end of the detection box 10 has elasticity, and the top end of the bottom plate 36 has elasticity. Through the pressure sensor 38, the product packaging bottle 11 inside the detection chamber 19 can be detected. At this time, the second three-way solenoid valve 35 works, and at the same time, the second solenoid valve 33 of the detection chamber 19 with the product packaging bottle 11 inside also works. Through the second three-way solenoid valve 35, the seventh connecting pipe 34 is opened, and through the second solenoid valve 33, the sixth connecting pipe 32 is opened. At this time, the air pressure inside the detection chamber 19 can be instantly reduced through the second three-way solenoid valve 35, the seventh connecting pipe 34, the fifth connecting pipe 31, the sixth connecting pipe 32, and the second solenoid valve 33. Then the second three-way solenoid valve 35 and the second solenoid valve 33 are instantly closed. The air pressure change inside the detection chamber 19 is detected through the air pressure detection sensor 39. If the air pressure inside the detection chamber 19 changes, the product packaging bottle 11 inside the corresponding detection chamber 19 is a product with unqualified sealing, otherwise it is a qualified product. After the detection is completed, one end of the seventh connecting pipe 34 is connected to the outside air through the second three-way solenoid valve 35. By opening the second solenoid valve 33, the inside of the detection chamber 19 can be made the same as the outside atmospheric pressure, which is convenient for the second electric push rod 9 to drive the detection box 10 to move upward, facilitating the sealing detection of this device and protecting the product packaging bottle 11 at the same time; It should be noted that a vacuum pump 14 is provided at one end of both the first vacuum chamber 12 and the second vacuum chamber 13, and a vacuum pressure display 15 is provided at one end of both the first vacuum chamber 12 and the second vacuum chamber 13. A pipe groove 29 is opened at one end of the workbench 1, and a baffle 30 is fixedly connected to one end of the pipe groove 29 to provide a vacuum environment and ensure that the product packaging bottle 11 stands upright normally. The baffle 30 prevents the first connecting pipe 16 and the seventh connecting pipe 34 from knocking down the product packaging bottle 11. The control panel 2 is electrically connected to an external power supply, and the control ends of the first conveyor belt 4, the second conveyor belt 5, the first electric push rod 8, the second electric push rod 9, the vacuum pump 14, and the vacuum pressure display 15 are all electrically connected to the control panel 2, facilitating the fully automatic operation of this device; Operating method of this device: Step 1: Feeding. The first vacuum chamber 12 and the second vacuum chamber 13 can be evacuated to a vacuum state by the vacuum pump 14, and the internal vacuum degree can be observed through the vacuum pressure display 15. The product packaging bottle 11 of the sample to be tested is conveyed to the bottom end of the detection box 10 through a set of first conveyor belts 4; Step 2: Fixing. The detection box 10 can be lowered by the second electric push rod 9 until the suction cup 22 abuts against the top end of the product packaging bottle 11. At this time, the spring 23 can be compressed by the suction cup 22, and under the action of the spring 23, the bottom end of the suction cup 22 is closely attached to the top end of the product packaging bottle 11. Then the first three-way solenoid valve 17 and the first solenoid valve 28 work. At this time, the air between the suction cup 22 and the product packaging bottle 11 enters the interior of the first vacuum chamber 12 through the fourth connecting pipe 27, the second connecting pipe 18, and the first connecting pipe 16, and the product packaging bottle 11 is sucked by the suction cup 22 under the action of the external atmospheric pressure; Step 3: Transferring. The detection box 10 is lifted by the second electric push rod 9, and the product packaging bottle 11 can be lifted by the suction cup 22. The product packaging bottle 11 is moved to the top end of the bottom plate 36 through the moving plate 6, the second electric push rod 9, the detection box 10, and the suction cup 22. The detection box 10 and the product packaging bottle 11 are lowered by the second electric push rod 9 so that the product packaging bottles 11 are respectively located at the top ends of the pressure sensors 38. The first three-way solenoid valve 17 works again to allow external air to enter the first connecting pipe 16, and at the same time, the first connecting pipe 16 at one end of the first vacuum chamber 12 is closed. At this time, the suction cup 22 no longer tightly sucks the product packaging bottle 11; Step 4: Detection. The product packaging bottle 11 inside the detection bin 19 can be detected through the pressure sensor 38. At this time, the second three-way solenoid valve 35 works, and at the same time, the second solenoid valve 33 inside the detection bin 19 with the product packaging bottle 11 also works. The seventh connecting pipe 34 is opened through the second three-way solenoid valve 35, and the sixth connecting pipe 32 is opened through the second solenoid valve 33. At this time, the air pressure inside the detection bin 19 can be instantaneously reduced through the second three-way solenoid valve 35, the seventh connecting pipe 34, the fifth connecting pipe 31, the sixth connecting pipe 32, and the second solenoid valve 33. Then the second three-way solenoid valve 35 and the second solenoid valve 33 are instantaneously closed, and the air pressure change inside the detection bin 19 is detected through the air pressure detection sensor 39. If the air pressure inside the detection bin 19 changes, the product packaging bottle 11 inside the corresponding detection bin 19 is a product with unqualified sealing, otherwise it is a qualified product. After the detection is completed, one end of the seventh connecting pipe 34 is connected to the outside air through the second three-way solenoid valve 35, and the inside of the detection bin 19 can be made to be the same as the outside atmospheric pressure by opening the second solenoid valve 33; Step 5: Transfer again. The suction cup 22 tightly sucks the product packaging bottle 11 again through the first three-way solenoid valve 17 and the first solenoid valve 28. The detection box 10 and the product packaging bottle 11 are moved to the first conveyor belt 4 on one side of the second conveyor belt 5 through the second electric push rod 9 and the first electric push rod 8. Then the detection box 10 is reset through the first electric push rod 8 and the second electric push rod 9, and the next group of product packaging bottles 11 is detected again; Step 6: Remove the unqualified product packaging bottle 11. The third electric push rod 42 corresponding to the unqualified product packaging bottle 11 works. The fixed sleeve 43 and the semi-circular sleeve plate 44 are moved to one side of the product packaging bottle 11 through the third electric push rod 42. Then the double-shaft motor 51 works, and the arc-shaped buckle plate 45 is moved through the gear 52 and the tooth groove 50 until one side of the limit block 49 fits against the inner wall of one end of the limit arc groove 48. At this time, the movement stops. The fixed sleeve 43, the semi-circular sleeve plate 44, and the product packaging bottle 11 can be moved through the third electric push rod 42 until the product packaging bottle 11 is at the top of the second conveyor belt 5. Then the arc-shaped buckle plate 45 is reset through the double-shaft motor 51 and the gear 52. Finally, the fixed sleeve 43 and the semi-circular sleeve plate 44 are reset again through the third electric push rod 42. At the same time, it can be detected through the third electric push rod 42 whether all the unqualified product packaging bottles 11 are at the top of the second conveyor belt 5. If there are unqualified product packaging bottles 11 at the top of the first conveyor belt 4, the second conveyor belt 5 will not start at this time, otherwise the second conveyor belt 5 starts and moves away the unqualified product packaging bottles 11.

[0018] First, the user uses a vacuum pump 14 to evacuate the first vacuum chamber 12 and the second vacuum chamber 13 to a vacuum state, and observes the internal vacuum degree through a vacuum pressure display 15. After the product packaging bottle 11 to be tested is conveyed to the bottom end of the detection box 10 through a group of first conveyor belts 4, at this time, the second electric push rod 9 can make the detection box 10 descend, so that the product packaging bottle 11 is inside the detection chamber 19 until the suction cup 22 abuts against the top end of the product packaging bottle 11. At the same time, under the action of pressure, the suction cup 22 can continue to move upward. At this time, the suction cup 22 can compress the spring 23. Then, under the action of the self-return elasticity of the spring 23, the bottom end of the suction cup 22 is tightly attached to the top end of the product packaging bottle 11. Then the first three-way solenoid valve 17 and the first solenoid valve 28 work. At this time, the air between the suction cup 22 and the product packaging bottle 11 enters the inside of the first vacuum chamber 12 through the fourth connecting pipe 27, the second connecting pipe 18 and the first connecting pipe 16, so as to slightly reduce the vacuum degree inside the first vacuum chamber 12, and at the same time, it can also reduce the air pressure inside the suction cup 22. Under the action of the external atmospheric pressure, the product packaging bottle 11 is sucked by the suction cup 22. The second electric push rod 9 is used to make the detection box 10 move upward until the bottom end of the limit ring 24 is attached to the inner wall of the bottom end of the limit groove 21. At this time, the limit ring 24 and the limit groove 21 can limit the movement of the suction cup 22. Then the product packaging bottle 11 can be lifted by the suction cup 22. The first electric push rod 8 can make the moving plate 6 slide on the surface of the sliding rod 7. The moving plate 6 drives the second electric push rod 9 to move, and the second electric push rod 9 drives the detection box 10, the suction cup 22 and the product packaging bottle 11 to move until the product packaging bottle 11 moves to the top end of the bottom plate 36. At this time, the second electric push rod 9 makes the detection box 10 and the product packaging bottle 11 descend, so that the product packaging bottles 11 are respectively on the top of the pressure sensors 38. At this time, the first three-way solenoid valve 17 works again, so that the external air enters the first connecting pipe 16, and at the same time, the first connecting pipe 16 at one end of the first vacuum chamber 12 is closed. At this time, the suction cup 22 no longer tightly sucks the product packaging bottle 11. The product packaging bottle 11 inside the detection chamber 19 can be detected by the pressure sensor 38. At this time, the second three-way solenoid valve 35 works, and at the same time, the second solenoid valve 33 with the product packaging bottle 11 inside the detection chamber 19 also works. The seventh connecting pipe 34 is opened by the second three-way solenoid valve 35, and the sixth connecting pipe 32 is opened by the second solenoid valve 33. At this time, the air pressure inside the detection chamber 19 can be instantaneously reduced through the second three-way solenoid valve 35, the seventh connecting pipe 34, the fifth connecting pipe 31, the sixth connecting pipe 32 and the second solenoid valve 33. Then the second three-way solenoid valve 35 and the second solenoid valve 33 are instantaneously closed. The air pressure change inside the detection chamber 19 is detected by the air pressure detection sensor 39. If the air pressure inside the detection chamber 19 changes, the product packaging bottle 11 corresponding to the detection chamber 19 at this time is a product with unqualified sealing, otherwise it is a qualified product. After the detection,One end of the seventh connecting pipe 34 is connected to the outside air through the second three-way solenoid valve 35. By opening the second solenoid valve 33, the inside of the detection chamber 19 can be made the same as the outside atmospheric pressure, thus facilitating the upward movement of the detection box 10 driven by the second electric push rod 9. At the same time, through the first three-way solenoid valve 17 and the first solenoid valve 28, the suction cup 22 tightly sucks the product packaging bottle 11 again. Through the second electric push rod 9 and the first electric push rod 8, the detection box 10 and the product packaging bottle 11 are moved to the first conveyor belt 4 on one side of the second conveyor belt 5. Then, through the first three-way solenoid valve 17 and the first solenoid valve 28, the suction cup 22 no longer tightly sucks the product packaging bottle 11. Finally, through the first electric push rod 8 and the second electric push rod 9, the detection box 10 is reset to facilitate the movement and detection of the next group of product packaging bottles 11 again. At the same time, the third electric push rod 42 corresponding to the unqualified product packaging bottle 11 works. Through the third electric push rod 42, the fixed sleeve 43 and the semi-circular sleeve plate 44 are moved to one side of the product packaging bottle 11. Then the double-shaft motor 51 works, and the output ends of the double-shaft motor 51 drive the two groups of gears 52 to rotate in the same direction at the same time. At this time, through the gears 52 and the tooth grooves 50, the arc-shaped buckle plate 45 moves. Through the arc-shaped chute 46 and the arc-shaped slide plate 47, the arc-shaped buckle plate 45 can be guided, so that the arc-shaped buckle plate 45 performs a circular motion. Through the limit arc groove 48 and the limit block 49, the moving distance of the arc-shaped buckle plate 45 can be limited to prevent the arc-shaped buckle plate 45 from moving out of the semi-circular sleeve plate 44. After the arc-shaped buckle plate 45 drives the limit block 49 until one side of the limit block 49 fits against the inner wall of one end of the limit arc groove 48, the movement stops at this time. Through the third electric push rod 42, the fixed sleeve 43, the semi-circular sleeve plate 44 and the product packaging bottle 11 can be moved until the product packaging bottle 11 is at the top of the second conveyor belt 5. Then, through the double-shaft motor 51 and the gears 52, the arc-shaped buckle plate 45 is reset. Finally, through the third electric push rod 42 again, the fixed sleeve 43 and the semi-circular sleeve plate 44 are reset. At the same time, through the third electric push rod 42, it can be detected whether all the unqualified product packaging bottles 11 are at the top of the second conveyor belt 5. If there are unqualified product packaging bottles 11 at the top of the first conveyor belt 4, the second conveyor belt 5 will not start at this time. On the contrary, the second conveyor belt 5 starts to move the unqualified product packaging bottles 11 away. This device can complete the detection work automatically, and at the same time, it can also separately take out and move away the unqualified product packaging bottles 11, further facilitating the user's detection work. This device is simple and convenient to operate, does not require multiple people to operate, further reduces the practical cost. At the same time, this device detects through a negative pressure method, and judges the sealing performance according to the change of pressure, will not cause any pollution or damage to the product packaging bottle 11, can also improve the detection accuracy, and can further reduce the user's use cost and maintenance cost.

At this time, the second three-way solenoid valve (35), the seventh connecting pipe (34), the fifth connecting pipe (31), the sixth connecting pipe (32) and the second solenoid valve (33) can instantly reduce the pressure. The air pressure inside the testing chamber (19) is tested, and then the second three-way solenoid valve (35) and the second solenoid valve (33) are closed instantly. The air pressure change inside the testing chamber (19) is tested by the air pressure testing sensor (39). If the air pressure inside the testing chamber (19) changes, the corresponding product packaging bottle (11) inside the testing chamber (19) is a sealed unqualified product, otherwise it is a qualified product. After the test is completed, one end of the seventh connecting pipe (34) is connected to the outside air through the second three-way solenoid valve (35). By opening the second solenoid valve (33), the inside of the testing chamber (19) can be made equal to the outside atmospheric pressure; Step 5: Transfer again, through the first three-way solenoid valve (17) and the first solenoid valve (28), the suction cup (22) again firmly sucks the product packaged bottle (11), and through the second electric push rod (9) and the first electric push rod (8), the detection box (10) and the product packaged bottle (11) are moved to the first conveyor belt (4) on the side of the second conveyor belt (5), and then the detection box (10) is reset through the first electric push rod (8) and the second electric push rod (9), and the next group of product packaged bottles (11) are detected again; Step 6: Take away the unqualified product packaging bottle (11), detect the third electric push rod (42) corresponding to the unqualified product packaging bottle (11) to work, and move the fixed sleeve (43) and the semicircular sleeve plate (44) to one side of the product packaging bottle (11) through the third electric push rod (42), and then the double-axis motor (51) works to move the arc buckle plate (45) through the gear (52) and the tooth groove (50) until one side of the limit block (49) fits with the inner wall of one end of the limit arc groove (48), and then stop moving. The fixed sleeve (43), the semicircular sleeve plate (44) and the product packaging bottle (11) can be moved through the third electric push rod (42). Until the product packaged bottles (11) are at the top of the second conveyor belt (5), the arc-shaped buckle plate (45) is reset by the double-axis motor (51) and the gear (52), and finally the fixing sleeve (43) and the semicircular sleeve plate (44) are reset again by the third electric push rod (42). At the same time, the third electric push rod (42) can detect whether all unqualified product packaged bottles (11) are at the top of the second conveyor belt (5). If there are unqualified product packaged bottles (11) at the top of the first conveyor belt (4), the second conveyor belt (5) will not start. Otherwise, the second conveyor belt (5) will start to move the unqualified product packaged bottles (11) away.
