Abstract

The invention discloses a PET bottle preform wall thickness measuring device which can be used to measure different specifications of PET bottle preform wall thicknesses and can be used to measure different curvatures of PET bottle performs. The PET bottle preform wall thickness measuring device comprises an optical fiber fixing device and a Y-type optical fiber. The optical fiber fixing device comprises an arc base plate, an arc installation chute, an angle adjusting shaft and a locking nut. The optical fiber fixing device can be used to realize equiangular interval adjustment. The PET bottlepreform wall thickness measuring device can realize multipoint real-time measurement to a PET bottle preform wall thicknesses so that measuring efficiency is increased. Simultaneously, the optical fiber fixing device can adjust the relative position relationship among optical fibers to meet the requirement of measuring the different specifications of PET bottle preform wall thicknesses by the optical fibers so as to realize the measurement of the different curvatures of PET bottle preforms.

Description

technical field [0001] The invention relates to the technical field of optical fiber sensing, in particular to a PET bottle blank wall thickness measuring device. Background technique [0002] Well known: PET (polyethylene terephthalate, (C 10 h 8 o 4 ) n ) has many advantages and is widely used in various daily necessities packaging. In the process of making PET bottles, the quality of PET preforms directly affects the quality of PET bottles, and the wall thickness of PET preforms is an important indicator for evaluating the quality of PET preforms. Therefore, it is particularly important to measure the wall thickness of PET preforms. At present, there are many measurement methods for PET preform wall thickness, such as direct measurement method, Hall effect method, ultrasonic measurement method, capacitance measurement method, optical image processing method and so on. However, these methods have some shortcomings, such as poor measurement accuracy and low efficiency...
