[0036] The implementation principle of this embodiment is as follows:

[0037] When Xu needs to detect the flatness of the outer surface of the sealed container, first place the container on the top of the roller 3. Subsequently, the first motor 13 starts to work to drive the driving wheel 16 to rotate. Utilize the friction between the driving wheel 16 and the transmission belt 15. Use the transmission belt 15 to make the sprocket 14 rotate to drive the roller 3 to rotate. Use the roller 3 to make the container rotate on the top of the roller 3.

[0038] When the container rotates, the contact rod 27 slides on the outer surface of the container. When there are unevennesses on the outer surface of the container, the support spring 26 will be compressed. Subsequently, the sliding cylinder 24 slides up and down. Under the action of the limit plate 25, it plays a role in limiting. At the same time, the capacitive pen 29 will slide up and down on the outside of the electric contact plate 30. Then use the signal transmitter 11 to make the waves received by the electric contact plate 30 be transmitted to the cloud to form a wavy line. When the outer surface of the container is flat, a straight line will be displayed in the data of the cloud. When there are unevennesses, a wavy line will be formed to judge whether the outer surface of the container is flat.

[0039] When facing containers with different radii, the third motor 23 drives the rotation of the threaded rod 22. By using the cooperation of the threaded rod 22 and the threaded hole 21, the mounting block 19 and the lifting block 20 are driven to move up and down. Since the guide rod 7 is fixedly arranged inside the mounting block 19 and the lifting block 20, when the lifting block 20 slides up and down, it can drive the mounting block 19 to slide outside the limiting rod 18, controlling the height of the contact rod 27 to adapt to containers with different radii. When horizontally detecting the flatness of the container, the first motor 13 starts to work and drives the screw rod 12 to rotate. By using the cooperation of the screw rod 12 and the threaded slider 10, the guide block 8 is driven to slide outside the guide rod 7, and at the same time, the flatness of the container is detected.

[0040] Compared with the prior art, the present utility model has the following beneficial effects over the prior art:

[0041] By adding the roller 3, it plays a role in driving the container to rotate. By adding the second motor 17, it plays a role in driving the transmission wheel 16 to rotate. Through the cooperation of the transmission wheel 16, the transmission belt 15 and the sheave 14, it plays a role in driving the roller 3 to rotate. By using the cooperation of the threaded rod 22 and the threaded hole 21, it plays a role in controlling the height of the measuring device 9. By using the above structures, containers with different radii can be driven to rotate, and its application range is increased. Through the cooperation of the contact rod 27 and the sliding cylinder 24, it plays a role in transmission.
