Printed sheet overlay detection system for full-automatic glazing machine

Abstract

The invention discloses a printed sheet overlay detection system for a full-automatic glazing machine. The system comprises a first support, a rotary shaft, a first rotary arm, a second rotary arm and a second support, wherein a shaft sleeve is arranged on the first support; the rotary shaft is arranged in the shaft sleeve; two or more than two rollers are arranged on the rotary shaft and fixedly connected with the rotary shaft through roller arms; one end of the first rotary arm is fixedly connected with one end of the rotary shaft, and the other end of the first rotary arm is provided with a fan-shaped rack; a gear is fixedly arranged on the second support; the gear is meshed with the fan-shaped rack; one end of the second rotary arm is fixedly connected with the gear, and a proximity switch is arranged at the other end; and a sensing plate is arranged at the lower part of the second support. The printed sheet overlay detection system for the full-automatic glazing machine is simple in structure, and can screen out overlaid printed sheets, so that local ink missing caused by printed sheet overlay is avoided, waste of the printed sheets in the production process is reduced, and efficiency of glazing of the printed sheets is improved.

Description

technical field [0001] The invention relates to the technical field of packaging and printing, in particular to a printed sheet overlap detection system for a fully automatic glazing machine. Background technique [0002] Fully automatic glazing machine is one of the main equipment in the packaging and printing industry, which in turn includes a paper feeder, a front paper feeding platform, a primer coating machine, an infrared dryer, a surface coating machine, an ultraviolet dryer, and a rear paper feeding platform and receiving machine. Due to the long conveying distance of the printed sheets, it is easy to produce position deviation, and often the printed sheets are skewed, causing overlapping and overlapping of adjacent printed sheets. In this case, during the oiling process, the edged sheets cannot be coated As for defects, due to the high operating speed of the equipment, it is almost impossible to manually check out such defective waste printed sheets, which will cau...

Problems solved by technology

Due to the long conveying distance of the printed sheets, it is easy to produce position deviation, and often the printed sheets are skewed, causing overlapping and overlapping of adjacent printed sheets. In this case, during the oiling process, the edged sheets cannot be coated As for defects, due to the high operating speed of the equipment, it is almost impossible to manually check out such defective waste printed sheets, which will cause unqualified printed sheets to be mixed into the next process, and even sent to users to cause quality accidents
