A kind of cleaning-sorting machine machinery segmented belt gain mechanism for measuring thick
[technical field]
The utility model relates to a kind of paper currency sorting thermomechanical components, is specifically related to a kind of cleaning-sorting machine machinery segmented belt gain mechanism for measuring thick.
[background technology]
Along with socioeconomic development, bank is increasing to the housekeeping amount of bank note.Also higher to the requirement of cleaning-sorting machine, the accuracy such as high-speed continuous measurement banknote thickness, wrinkle, flanging, knuckle, adhesive paper, adhesive tape are had to higher requirement.This test item is new and old, damaged to accurate sorting, stickup coin is extremely important.Erroneous judgement and poor repeatability will reduce the efficiency of paper currency sorting work.
Existing cleaning-sorting machine thickness measurement sensor precision is low, poor reliability, and manufacture difficulty is large.Existing machinery sectional type mechanism for measuring thick, formed by drive roll below and multiple engaged wheels above, take turns up and down axis parallel, multiple engaged wheel supports, string is on a public major axis, tested bank note is during by upper lower whorl gap, each engaged wheel support can rotate around major axis. and be the thickness of tested bank note, be converted into rotational angle variable. be converted to again electric signal output. multiple engaged wheel support independence continuous wave output thickness datas, can obtain thickness chart picture. but engaged wheel support string is on public major axis, measuring error is brought in the gap in axle and hole, when carefully moving, public major axis easily shakes, generation interferes with each other signal and brings Measurement sensibility poor. and major axis runic is long-pending large.
Existing thickness measurement sensor, by the thickness of tested bank note, does not gain in the mechanism of changing rotational angle variable into, is converted to electric signal very faint.For improve Measurement Resolution need join magnification at high multiple circuit, but also will on chat error and disturb simultaneously amplification. this thatch shield perplexs the development of cleaning-sorting machine manufacturing for a long time.
