Linear PET bottle blank defect detection device

The invention relates to a linear PET (Polyethylene Terephthalate) bottle blank defect detection device which is characterized in that a conveying mechanism and a removing mechanism are mounted on a conveying frame, a feeding slide way, a feeding assembly, a detection assembly, a discharging assembly and a discharging slide way are mounted on a feeding frame, the feeding slide way conveys bottle blanks to the feeding assembly, the feeding assembly clamps the bottle blanks and conveys the bottle blanks to the conveying mechanism, and the removing mechanism is mounted on the conveying frame; the conveying mechanism drives bottle blanks to move forwards, bottle blank detection is completed through the detection assembly, the removing mechanism removes unqualified bottle blanks detected by the detection assembly, and qualified bottle blanks detected by the detection assembly are clamped and conveyed to the discharging slide way through the discharging assembly. The linear conveying mode is adopted, the structure
