Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] like Figure 1-Figure 3 As shown in the figure, a paper feeding device of a beta-ray method atmospheric particulate matter monitor of the present invention includes an installation main frame 1, and the front side of the installation main frame 1 is provided with a paper feeding wheel 2, a paper delivery wheel 3 and a pair of rollers that are axially parallel to each other. 4, 5, in which the feeding roller 2 and the feeding roller 3 are located at the same level, and are distributed left and right on the front of the main frame 1. The feeding roller 2 and the feeding roller 3 are respectively rotated and installed on the Install the front of the main frame. The two rollers 4 and 5 are located at the same level, and are distributed to the left and right on the front of the main frame 1. At the same time, the level of the two rollers 4 and 5 is l...

The invention discloses a paper feeding device of a beta-ray method atmospheric particulate monitor. The device includes an installation main frame, a paper releasing wheel and a paper collecting wheel which are arranged in parallel left and right are respectively mounted on the mounting main frame; the paper collecting wheel is connected with a driving motor; rollers which are arranged in parallel left and right are also mounted on the mounting main frame; a photoelectric switch separation blade is arranged on a wheel shaft of the right roller; a photoelectric switch is arranged near the photoelectric switch separation blade; the photoelectric switch separation blade passes through the photoelectric switch; the filter paper is wound on the paper unwinding wheel; the paper is wound on a paper winding wheel through a left roller and a right roller respectively; paper feeding of the filter paper is pulled through rotation of the claw machine motor on the paper collecting wheel, the filter paper drives the idler wheel on the right and the photoelectric switch blocking piece to rotate, on-off of the photoelectric switch is controlled, and therefore the rotation amount of the motor andthe paper feeding amount of the filter paper are accurately monitored, and the structure is simple, reliable, convenient, practical and accurate in control.
Description
technical field [0001] The invention relates to the field of paper feeding devices, in particular to a paper feeding device of a beta-ray method atmospheric particle monitoring instrument. Background technique [0002] Atmospheric particulate matter is a general term for solid or liquid particulate matter dispersed in the atmosphere. The particle size of atmospheric particles is different, and the parts of the air that are inhaled and deposited in the respiratory system are different, and the harm to the body is also different. Those larger than 5 μm are mostly retained in the upper airways, and those smaller than 5 μm are mostly retained in the bronchioles and alveoli. As people pay more and more attention to the health hazards of atmospheric particulate matter, the monitoring technology of atmospheric particulate matter is also more and more advanced. In order to improve the overall reliability of monitoring data, the paper feeder is particularly important. Most of the ...
