Abstract
The invention discloses a paper feeding device for a beta ray-method PM10 online monitor, which comprises a mainboard (11), a driving shaft (17), a fixed shaft (5) and a claw-pole motor (1), wherein the claw-pole motor (1) is in transmission connection with the driving shaft (17); a driven shaft (8) is arranged above filter paper (2) and is provided with a rubber roll (9); the fixed shaft (50 is sleeved with a fixed shaft sleeve (7); a pressing plate (4) is arranged between the fixed shaft sleeve (7) and the driven shaft (8); the fixed shaft sleeve (7) is provided with symmetrical torsion springs to squeeze the pressing plate (4); and the claw-pole motor (1) is provided with a positioning disc (12), and a photoelectric breaker (2) matched with the positioning disc (12) is arranged on the motor body so as to jointly control the rotation of the claw-pole motor (1). The filter paper moves steadily without paper breaking; and the distance between adjacent sampling spots always keeps consistent, and the counting accuracy is high.
Description
Technical field
The present invention relates to β rays method PM10 on-line monitoring instrument chart drive assembly.
Background technology
β rays method PM10 on-line monitoring instrument is one of China's main monitoring instrument of measuring pellet in the atmosphere at present.In observation process, calibration, sampling, counting and the output link that is absolutely necessary, and in these links, need filter paper accurately to be moved to the left certain distance sometimes needs filter paper certain distance that accurately moves right sometimes.The filter paper of existing chart drive assembly is to be wound on the axle, realize moving of filter paper by the drive unit drive shaft turns, the rotation of axle is by each quantitative the moving of rotating identical angle realization filter paper of control rotating shaft, because axle rotates the circumference arc length difference under the identical pairing different radii of angle, cause each filter paper amount of movement difference, do not reach the requirement that requires identical filter paper amount of movement in the production.
Summary of the invention
Purpose of the present invention is exactly to solve the different problem of the β rays method PM10 on-line monitoring each filter paper amount of movement of instrument chart drive assembly.
The technical solution used in the present invention is: a kind of β rays method PM10 on-line monitoring instrument chart drive assembly, it is characterized in that it comprises mainboard, is positioned at the filter paper underside and is connected main drive shaft on the mainboard, is parallel to main drive shaft and is fixedly connected on dead axle on the mainboard and be fixed on claw-pole motor on the mainboard, described claw-pole motor and main drive shaft driving coupling drive main drive shaft and rotate; Described filter paper top is provided with the driven shaft parallel with main drive shaft, driven shaft is provided with two can be around the rubber-surfaced roll of driven shaft rotation, be set with the dead axle cover on the dead axle, be provided with pressing plate between dead axle cover and the driven shaft, driven shaft and dead axle cover connect with the pressing plate two ends are movable respectively, and dead axle puts the torsion spring extruding pressing plate that is provided with symmetry; Claw-pole motor is provided with positioning disk, and fuselage is provided with the photo interrupter that cooperates with positioning disk, and common the realization rotated control to claw-pole motor.
The employing technique scheme, the mobile of filter paper is to move with the main drive shaft straight line, and main drive shaft is realized control by the rotation of claw-pole motor, so the identical angle of the each rotation of main drive shaft, and the amount of movement of filter paper is identical.
Beneficial effect of the present invention is: 1, filter paper moves steadily, does not have disconnected paper phenomenon; 2, be encased in filter paper from filter paper and use up the whole process, the distance between the neighbouring sample spot remains unanimity; When 3, filter paper was moved to the left a distance and is A, when sampling was finished, filter paper can be adopted to the right more like clockwork and return that to move a distance be A, thereby has improved the precision of postorder G-M Geiger tube rolling counters forward.
