[0002] In the plastic container packaging industry, the semi-finished preforms used in the two-step method of blowing bottles are made by heating and melting the raw materials through an injection molding machine and then injecting them into a matching mold. During the processing of the preforms, when the raw material properties and the injection molding process fluctuate, or when the injection mold is not installed in place, and when the new injection mold is just produced, it is easy to affect the quality of the preforms. If the lack of material and flash can be visually inspected by the naked eye, they can be handled in time by adjusting the injection molding process and reinstalling the mold, which will not cause a great impact. However, when there is a slight deviation in the verticality of the preform, it is generally difficult to detect it with the naked eye, unless there are individual special cases such as "banana preforms". In order to ensure that the verticality of the preforms is controlled within the standard range, it is necessary to detect the verticality data of the preforms on site in a timely manner.
