The fixed disk 18 is sleeved and fixedly connected with the sliding sleeve 13, and the fixed disk 18 is arranged above the pressure plate 2, and the fixed disk 18 is fixedly connected with the pressure plate 2 through the connecting column 23. The sliding sleeve 13 is also fixedly connected with a transition sleeve 15, and the transition sleeve 15 is arranged above the fixed disk 18. The transition sleeve 15 is fixedly connected with the inner ring of the slewing bearing 14, and the cam 11 is fixedly connected with the outer ring of the slewing bearing 14. The upper part of the key 17 is fixedly connected with the fixed disk 18 and the pressure plate 2 respectively, and the fixed seat 12 is provided with a guide groove 19, and the bottom of the key 17 is inserted into the guide groove 19. At this point, the fixed seat 12 rotates with the transmission shaft 7, and the fixed seat 12 drives the pressure plate 2, the fixed plate 18, the sliding sleeve 13 and the inner ring of the slewing bearing 14 to rotate through the key 17. The transmission shaft 7 is a cavity type, and a transmission rod is rotatably connected in the inner cavity of the transmission shaft 7. The top end of the transmission rod passes out of the inner cavity of the transmission shaft 7 and is matched with a guide sleeve, which is connected to the sliding sleeve 13. When the transmission rod and the transmission shaft 7 rotate relative to each other, the guide sleeve drives the sliding sleeve 13, the slewing bearing 14 and the pressure plate 2 to move upward, thereby changing the distance between the pressure plate 2 and the rotating disk 1.

The bottom end of the packaging bottle 6 is placed on the pad 403, and the top end of the packaging bottle 6 is pressed against the pressure rod 5. When the turntable 2 drives the second lifting assembly 10 to be placed in the lifting section of the cam 11, the pressure rod 5 is separated from the packaging bottle 6.

[0030] The tray 16 is connected with a connecting rod 24, which extends upward in the vertical direction, and is connected to a support arm 21, and a locking sleeve 22 is connected to the end of the support arm 21. A locking cylinder 2201 is fixed inside the locking sleeve 22, and a support column 20 is circumferentially arranged outside the turntable 1. The locking sleeve 22 is slidably connected to the support column 20, and can be extended through the telescopic end of the locking cylinder 2201 to press against the support column 20, but the locking sleeve 22 and the support column 20 are relatively fixed.

[0031] The linear conveyor line 27 is arranged on one side of the turntable 1, and the bottle inlet star wheel assembly 28 and the bottle outlet star wheel assembly 29 are arranged tangent to the linear conveyor line 27, and the bottle inlet star wheel assembly 28 and the bottle outlet star wheel assembly 29 are placed at both ends of the lifting section of the cam 11.

[0032] The working process of the device is as follows: the bottle 6 to be inspected enters from one end of the linear conveyor line 1, passes through the bottle inlet star wheel assembly 28 and is placed on the inspection station 4 of the turntable 1; the pressure rod 5 moves downward to the top of the bottle 6 to fix it to prevent it from tipping over; at the same time, the light source board 8 moves downward to one side of the bottle 6 to provide sufficient light for the inspection terminal 3; the bottle 6 rotates under the drive of the inspection station 4 and revolves under the drive of the turntable 1; when the bottle 6 moves to the bottle outlet star wheel assembly 29, the pressure rod 5 and the light source board 8 rise, and the bottle 6 passes through the bottle outlet star wheel assembly 29 and is transferred to the linear conveyor line 1 again. When the height of the bottle 6 changes, the driving rod is rotated, so that the guide sleeve drives the sliding sleeve 13, the pressure plate 2, the single spring key of the first lifting assembly 9 and the second lifting assembly 10 to move upward.
