Description
Technical field
The utility model belongs on the tobacco processing line device technique field of tobacco being carried out measuring fixed amount.Can be applicable on the tobacco threshing redrying line, with front and back material transfer equipment cooperating, the control mass flow.Also can be applicable on the tobacco processing line, with front and back material transfer equipment cooperating, the control mass flow.
Background technology
On existing tobacco processing line, mass flow is mainly controlled by the flow controlling unit that feeding machine (or ribbon conveyer), quantitative measuring device and belted electronic balance (or ribbon conveyer) are formed.Control principle is: under electric control system controls; Upstream equipment (for example feeding machine) is sent into material in the quantitative measuring device and material is piled up in quantitative measuring device; Material downstream equipment (belted electronic balance or ribbon conveyer) conveyer belt pulling continually behind quantity tube is transported to upstream device by certain volume down.Can realize control through changing upstream device (belted electronic balance or ribbon conveyer) conveyer belt speed to mass flow.The piling height of material in quantitative measuring device detects subsequent signal to electric-control system through Charge level measurer spare, and electric-control system is realized the constant of flow according to material level signal controlling upstream and downstream equipment.For example: when material is in low material level (or middle material level), upstream equipment specified rate metering device feed; When material level was in high charge level, upstream equipment stopped feed.
Yet; Present quantitative measuring device (for example material disperses in quantitative measuring device, quantitative measuring device specific region moment fall more material, caking or large scale material and continue through test point etc.) under individual station or operating mode that some are complicated is easy to generate wrong material level signal; Cause electric-control system to take wrong operation, cause the fluctuation of subsequent production index.For example: cigar mill's throwing line perfuming station; Because it is less at this station tobacco density; Pipe tobacco is subject to airflow influence in the process that falls into quantitative measuring device from upstream equipment, is created in the phenomenon that specific region moment falls more pipe tobacco and blocks corresponding Charge level measurer spare.Though other local not how many pipe tobaccos in this material level quantitative measuring device; But because this Charge level measurer spare is blocked; Sent the rub-out signal that this material level has material to electric-control system, electric-control system also can only take corresponding actions according to this wrong material level signal.If the Charge level measurer spare that is blocked is the high charge level detection means, then its material level signal of sending to electric-control system is high charge level has material.Electric-control system receives after wrong high charge level has the material signal, and electric-control system stops the upstream equipment operation in order to avoid cause putty with follow procedure.Simultaneously, downstream electronic belt conveyer scale or ribbon conveyer continue operation with pipe tobacco take out of quantitative measuring device with dependable flow continuously.Yet actual situation but is a quantitative measuring device and less than material, a small amount of pipe tobacco that blocks Charge level measurer spare is only arranged in a certain section.Though after upstream device operation a period of time, the conducting again of high charge level detection means, electric-control system instruction upstream equipment specified rate metering device feed.The pipe tobacco speed of filling can not be very fast, few for a long time phenomenon when so just having produced on belted electronic balance pipe tobacco.Caused the fluctuation of mass flow, follow-up perfuming precision has been exerted an influence.The major reason that produces wrong material level signal is exactly that quantitative measuring device level of filler material test point is single and the position is unreasonable, can't adapt to some special operation conditions, thereby produce wrong material level signal.
