Description

Technical Field

[0001] The utility model relates to the technical field of pipe material detection equipment, in particular to a pipe material size detection mechanism used for discharging plastic pipes. Background Art

[0002] The pipe is produced on the production line and cut into a plastic pipe. The discharged plastic pipe needs to be randomly sampled by quality inspectors to check whether its inner diameter and outer diameter size data are qualified. The finished product with qualified data can be offline. The existing plastic pipe size detection is generally performed by quality inspectors manually selecting a position on the surface of the pipe for detection. This method of detection is not comprehensive enough, especially for long pipes. When testing, it is necessary to conduct more comprehensive inspections at multiple positions to ensure uniformity and consistency within the error range to avoid large deviations in pipe size. For this reason, we provide a pipe size detection mechanism for plastic pipe discharge. Utility Model Content
