Abstract
The utility model relates to a warning device for controlling the pressure of a powdered toner classifying procedure air-leading pipeline. The warning device comprises an air-leading pipeline, and also comprises an electro-connecting pressure gauge, a warner, an air-delivering pipe and leads wherein the electro-connecting pressure gauge is connected on one side of the air-leading pipeline by the air-delivering pipe, and the warner is connected with the electro-connecting pressure gauge by the leads. By adopting the warning device, the air-taking pressure in the classifying procedure is controlled in the overall powdered toner manufacturing process, thus the subpressure of a powdered toner classifying chamber is ensured, the size distribution of powdered toner is ensured and the product quality is increased.
Description
Technical field
The utility model relates to duplicating machine and ink powder of laser printer process equipment, particularly a kind ofly is used to control ink powder classification operation induced duct road pressure warning unit.
Background technology
For duplicating machine, the employed ink powder of laser printer, the size-grade distribution of ink powder directly influences its product quality.In the process that ink powder is produced, the control of the granularity of ink powder mainly is to finish in the classification operation, and the classification operation is provided with the air channel that the different grain size toner particles is passed through, and realizes the ink powder size-grade distribution by the pressure of controlling each air channel.Usually the main cause that influences air channel pressure is exactly the sticking powder amount on the filter cloth bag, promptly in the process that cyclone separator is separated the gas in each air channel material, the gaseous mixture that produces is discharged by the filter cloth bag, superfine powder particle in the gaseous mixture is bonded at and stops up the filter cloth bag on the filter cloth bag, influences air channel pressure.Common control method is: regularly get ink powder classification product sample, and on-the-spot its size-grade distribution that detects, the pressure of adjusting corresponding air channel according to testing result reaches requirement up to the ink powder size-grade distribution.Because superfine powder is blocked the filter cloth bag easily, air inducing pressure can change at any time influences Granularity Distribution, and this influence will could show in detection next time.That is to say that this control method affects the stability of product quality to a great extent, also increased workload.
Summary of the invention:
The utility model is to solve above deficiency, provides a kind of especially and just reports to the police when the pressure that enters the air channel does not satisfy setting value, reminds adjustment air inducing pressure, guarantees pressure in setting range, the warning device thereby assurance ink powder size-grade distribution meets the requirements.
For achieving the above object, the technical scheme that the utility model is taked is: be used to control ink powder classification operation induced duct road pressure warning unit, comprise the air inducing pipeline, also comprise electro connecting pressure gauge, alarm, gas piping, lead, electro connecting pressure gauge is connected a side of air inducing pipeline by gas piping, and described alarm is connected with electro connecting pressure gauge by lead.
The beneficial effects of the utility model are, make the air intake pressure overall process of the classification operation in the ink powder production run controlled, have guaranteed the pressure of ink powder grading room negative pressure, thereby have guaranteed the size-grade distribution of ink powder.
Description of drawings
Fig. 1 is a structural representation of the present utility model and as Figure of abstract.
Embodiment
As shown in the figure, be used to control ink powder classification operation induced duct road pressure warning unit, comprise air inducing pipeline 5, also comprise electro connecting pressure gauge 1, alarm 2, gas piping 3, lead 4, electro connecting pressure gauge 1 is connected a side of air inducing pipeline 5 by fast connector, gas piping 3, and alarm is connected with electro connecting pressure gauge with lead by connection terminal.
Material to be fractionated enters oscillating feeder by loading hopper, under the suction function that induced draft fan produces, spray into the ink powder grading room at a high speed by the air inducing pipeline, under the effect of downdraught, do parabolic motion, because granule size difference, the running orbit difference, bulky grain flies to such an extent that far return pulverizing process as the grain granule materials and pulverize again, and granule flies nearerly that to return raw material as micro mist salty newly mixing, and the stage casing particle is that qualified semi-manufacture enter next procedure.Because the common main cause that influences air channel pressure is exactly the sticking powder amount on the filter cloth bag, promptly in the process that cyclone separator is separated the gas in each air channel material, the gaseous mixture that produces is discharged by the filter cloth bag, superfine powder particle in the gaseous mixture is bonded at and stops up the filter cloth bag on the filter cloth bag, influences the air inducing pipeline pressure.When the vacuum tightness in the grading room did not meet setting numerical value, electro connecting pressure gauge was passed to alarm with signal, sound and light alarm, pressure is paid close attention in prompting, or adjusts pressure or cleaning filter cloth bag, guarantees that the grading room negative pressure is in specialized range, thereby guarantee classification product size-grade distribution, improve the quality of products.
