Test paper quantity statistics device and working method thereof

Abstract

The invention discloses a test paper quantity counting device and a working method thereof. A support, a sliding rail, an upper baffle and a lower baffle are arranged, wherein the upper baffle can move up and down along the sliding rail, a distance between the upper baffle and the lower baffle is adjusted, test papers with different thicknesses can be measured, a first polar plate and a second polar plate of a capacitive sensor are respectively arranged at the bottom of the upper baffle and the bottom of the lower baffle, the capacitance measured by the capacitance sensor is changed by utilizing different thicknesses of media between polar plates of the capacitance sensor, the thickness of a test paper between the upper baffle and the lower baffle is measured, therefore, the number of testpapers is calculated, the upper baffle capable of moving along a slide rail can compact a to-be-tested roll, the upper baffle is supported on the support through the sliding rail, the upper baffle can only move in the direction of the sliding rail, that the opposite area of the two polar plates is constant is guaranteed, the number of the test papers can be rapidly and accurately measured, the structure is simple, cost is low, and the test papers are not damaged.

Description

technical field [0001] The invention relates to the field of paper counting, in particular to a test paper quantity counting device and a working method thereof. Background technique [0002] During the examination process in the school, multiple copies of one test paper will be made and split according to the class, which requires counting the test papers. [0003] Traditional paper counting methods mainly include manual counting method and mechanical equipment counting method. The efficiency of manual counting method is very low, and its accuracy is also affected by human factors, which may cause damage to paper; the typical application of mechanical equipment counting method is to count money Machine, which has strict requirements on paper specifications, is not suitable for counting test papers. The newer technical method is to count paper based on machine vision technology, but this method requires high equipment and complicated technology, so it is not suitable for so...

Problems solved by technology

[0003] Traditional paper counting methods mainly include manual counting method and mechanical equipment counting method. The efficiency of manual counting method is very low, and its accuracy is also affected by human factors, which may cause damage to paper; the typical application of mechanical equipment counting method is to count money machine, which has strict requirements on paper specifications, and is not suitable for counting test papers

The newer technical method is to count paper based on machine vision technology, but this method requires high equipment and complicated technology, so it is not suitable for some small occasions
