Paper dividing device and paper dividing method

Abstract

The invention discloses a paper dividing device and a paper dividing method. The paper dividing device comprises a motor, a synchronized belt, a driving wheel, at least one planet wheel and an air pump; the motor drives the driving wheel to rotate by the synchronized belt; the driving wheel and the at least one planet wheel are arranged in a linkage mode so that when being rotated, the driving wheel can drive the at least one planet wheel to rotate; the planet wheel is provided with a paper sucking tip and branch air suction pipes; the paper sucking tip is provided with an air suction channel of which one end is an air suction port while the other end is of an air inlet; when the paper sucking tip is used for rotating, the air inlet is communicated with the branch air suction pipes; the air suction port is adjacent to an external paper sheet; the air pump is respectively communicated with each branch air suction pipe and is used for sucking air from the branch air suction pipes when being controlled, and negative pressure is formed at the corresponding air suction port to suck the external paper sheet. By adopting the scheme, the paper dividing device is simple in structure, low in cost and convenient to apply, has low quality demands on the paper sheet, is suitable for the paper sheets of different standards, effectively avoids the paper clamping and has better practical value.

Description

technical field [0001] The invention relates to the field of paper separation, in particular to a paper separation device and a paper separation method. Background technique [0002] Teachers in colleges and universities are burdened with heavy teaching and scientific research tasks. Every final exam requires a lot of manpower to distribute test papers, which is time-consuming and laborious, wasting teachers’ precious time, and manual counting of test papers is prone to errors. Once the number is wrong, the invigilator needs to ask the test papers one by one , It is not conducive to the teacher's invigilation and also affects the normal answer sheet of the students. Therefore, teachers in school are in urgent need of a machine with low cost, small size, and fast and accurate counting of paper. This equipment must have the following features: accurate counting of papers, low cost, small size, can count B4 test papers and papers below B4, simple and reliable. [0003] At pre...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no machine for counting examination papers in colleges and universities on the market. The commonly used banknote counting machines are expensive to manufacture and are not suitable for counting examination papers in colleges. the cost is too high

[0004] Other related equipment on the market generally have the following problems: complex structure, large volume, high price; poor accuracy of counting paper, high quality requirements for paper quality, and serious impact on counting accuracy when paper is damp or charged with static electricity; strong pertinence , strictly limit the size of the paper when counting paper

When the weather is humid or the paper is charged, it is very easy to jam or twist multiple pages at a time. If the paper is folded, it is easy to jam. Once the paper is jammed, it is very inconvenient to take out the paper.
