Embodiment Construction

[0019] like Figure 1-Figure 7 As shown, the double sheet detection device of the present invention includes a bracket 1 , a left lever 21 , a right lever 22 , a thickness measuring wheel 3 , a photoelectric sensor 4 and a paper biting wheel 5 .

[0020] like figure 1 , figure 2 , image 3 and Figure 4 As shown, a bracket 1 is provided on one side of the circumferential surface of the biting wheel 5 . Described support 1 is vertical direction, and support 1 top is fixedly connected with the right part of support upper rod 11, and the left part of support upper rod 11 is hingedly connected with left lever 21 by axle 211. A compression spring 112 is provided between the bracket 1 and the left lever 21 . The compression spring 112 is located on the lower side of the shaft 211 . The middle part of the upper rod 11 of the support is fixedly connected with the upper part of the clip spring guide rail 111 . The compression spring 112 passes through the through hole in the mi...

Abstract

The invention relates to a detection device, in particular to a double-sheet detection device for measuring paper in the transport process, and aims to provide a double-sheet detection device which saves paper, time and labor and improves the quality of products. The double-sheet detection device is characterized in that six to eight sheets of paper which is the same as paper on a paper biting wheel is placed on a fixing block, a threaded rod is controlled to compress the paper to adjust the gap between a thickness measuring wheel and the paper biting wheel, a gap between a wheel raised head and the circumferential surface of the paper biting wheel which is larger than the thickness of a sheet of paper and smaller than the thickness of two sheets of paper can be conveniently found, the complex operation of thickness calibration of workers is omitted, and then a plurality of sheets of paper can conveniently and smoothly pass the paper biting wheel one by one. When two sheets of paper passes, the thickness measuring wheel can be triggered to rotate, the relative position between a balance weight induction block and a photoelectric induction device changes, the photoelectric induction device can detect transport of two sheets of paper, and therefore printing quality and waste of paper are prevented from being affected in the printing process of the two sheets of paper.

Description

technical field [0001] The invention relates to a detection device, in particular to a double-sheet detection device used for measuring paper in the transportation process of a cover folding machine. Background technique [0002] The cover folding machine needs to complete the process of transporting the piles of covers to the book processing line through the bite wheel to provide cover paper for the book. However, if the biting wheel transports the double-covered paper to the assembly line, there will be defective products of two-covered books, and paper will be wasted. The original double-sheet detection equipment was time-consuming and laborious to adjust when dealing with cover papers of different thicknesses. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-sheet detection device that saves paper, can quickly adjust cover paper of different specifications during production, saves time and effort, an...
