Detecting device of color plate printing production line

Abstract

The invention discloses a detecting device of a color plate printing production line. The detecting device of the color plate printing production line comprises a fixing bottom plate; lower groove steel is fixed at the fixing bottom plate; vertical square tubes are fixed at the two ends of the lower groove steel in an inserting manner and the upper ends of the square tubes are fixed at upper groove steel in an inserting manner; a light screen sensor is arranged between the lower groove steel and the upper groove steel and comprises an infrared emitting tube and an infrared receiving tube; theinfrared emitting tube and the infrared receiving tube are respectively fixed in the upper groove steel and the lower groove steel in an inserting manner; L-shaped auxiliary supports are fixed on thefront side walls and the rear side walls of the square tubes; the lower ends of the auxiliary supports are fixed at the fixing bottom plate and bearing seats are fixed at the upper end surfaces of theauxiliary supports; the two ends of a carrier roller is hinged to the bearing seats and vertical inserting grooves are formed in the square tubes and located below the carrier roller; a grating sensor is arranged between the square tubes and consists of an emitter and a receiver which are correspondingly fixed in the inserting grooves of the square tubes. The device is capable of detecting the transportation process of a steel strip and detecting whether the steel strip is slack during the transportation at the same time.

Description

Technical field: [0001] The invention relates to the technical field of steel strip detection equipment, and more particularly to a detection device on a color steel plate printing production line. Background technique: [0002] As a brand-new building and decoration material, printed decorative color steel plate is a high-grade color-coated plate used in star-rated buildings and top-level decoration in the world today. Printing and other processes, and then rolled into a finished product. The blank steel needs a corresponding detection device to detect whether there is a steel strip during the conveying process between each process, so as to prepare for the next process. The commonly used detection mechanism is to use a photoelectric sensor for detection, but it can only detect whether the steel strip is There is, the tension of the steel belt during the conveying process cannot be detected. Invention content: [0003] The purpose of the present invention is to address ...
