A thickness detection device for PET strapping during winding

Abstract

This utility model discloses a thickness detection device for PET strapping during winding, relating to the field of strapping production. It includes a unidirectionally moving strapping during PET strapping winding and two sets of horizontal guide rollers. A measuring guide roller is positioned between the two sets of horizontal guide rollers. A detection base is positioned above the measuring guide rollers. The front and rear side walls of the inner cavity of the detection base are equipped with an upper laser sensor switch and a lower laser sensor switch, each including a receiving and transmitting device. An upper sleeve is connected to the inside of the detection base via a lifting mechanism. A movable rod extending from the bottom of the upper sleeve is movably engaged within the inner cavity of the upper sleeve. The bottom of the movable rod is connected to a contact block via a magnetorheological damping buffer assembly. A laser rangefinder transmitter is positioned at the top of the inner cavity of the upper sleeve, and a laser rangefinder receiver and a force sensor are positioned at the top of the movable rod. This application enables real-time thickness detection during PET strapping winding, achieving improved detection accuracy, adaptive pressure adjustment, and reduced material waste.
