Description
Technical field:
The present invention relates to the dynamic weighing equipment technical field, specifically a kind of suspended electronic belt conveyor scale using that can detect the tare weight value in real time.
Background technology
Belted electronic balance is a kind of bulk material dynamic measurement and opertaing device that is widely used in industries such as tobacco, metallurgy, chemical industry, for a long time, the stability of metering is all solved at all, the principal element that influences the belted electronic balance metering accuracy comes from belt tension variation, the deformation of scale frame and laying dust, and the influence of these principal elements finally all is reflected as the variation of tare weight value.Belted electronic balance can be divided into simple lever, double lever, cantilevered, type such as floated by the version of scale frame.From theoretical analysis and practical effect, suspended electronic belt conveyor scale using is the belted electronic balance the most accurately of metering at present.Even but suspended electronic belt conveyor scale using can't accomplish that also long-term stable operation measures state accurately, the main cause that influences its steady operation just is to guarantee a stable tare weight value.
Summary of the invention
The objective of the invention is to overcome prior art problems, provide a kind of and can detect the tare weight value in real time, guarantee the stable accurately suspended electronic belt conveyor scale using of work.
The present invention uses simple structure to realize floated weighing structure to guarantee the accuracy of metering, and the device that secondly is design one online detection tare weight value is with real-time detection tare weight value.By the realization of above-mentioned measure, can solve the problem of the ubiquitous poor stability of present belt conveyer scale, for the accurate metering of stablizing of belted electronic balance provides a solution.
Suspended electronic belt conveyor scale using of the present invention mainly is made of band conveyor, floated single-idler receptor, online in real time tare weight value detection device, a plurality of LOAD CELLS, belt speed pick-up unit, signal transmitting device and signal processor; Single-idler receptor is directly supported by LOAD CELLS and suspends, constitute floated weighing platform and place in the band conveyor by two or more single-idler receptors, online in real time tare weight value detection device connects LOAD CELLS, LOAD CELLS connects the signal transmitting device, the signal transmitting device is connected with signal processor, and the belt speed pick-up unit is with the contact of band conveyor belt and be connected signal processor.
Wherein, floated weighing platform and adjacent two transition carrying rollers have constituted between the Weighing Area of belted electronic balance; Described online in real time tare weight value detection device is floated single-idler receptor; Described LOAD CELLS is LOAD CELLS simulation or numeral; Described signal transmitting device amplifies and transmitter for signal simulation or numeral; Described belt speed pick-up unit is the roller that speed measuring coder is housed; Described signal processor can be PLC, can be computing machine, can be industrial computer, also can be secondary instrument.
The present invention has the following advantages compared with the prior art:
(1) owing on return belt, adopted the online tare weight value detection device that constitutes by floated single-idler receptor, the tare weight value of any time can be accurately detected in real time, and instantaneous mass net weight accurately can be obtained behind the material weight+tare weight signal operation between Weighing Area.In the production run, no matter how the tare weight value changes, and the tare weight value detection device can both accurately detect the tare weight signal in real time, for the accurate work of stablizing of belted electronic balance provides reliable guarantee.
(2) adopted the floated weighing platform that constitutes by two or more floated single-idler receptors, compactness simple for structure, accuracy of measuring height, convenient for installation and maintenance.
(3) signal of simulation LOAD CELLS or digital weighing sensor is all handled by the signal transmitting device separately, has avoided the problem that angular difference can't effectively be adjusted under the conventional balance plate terminal box processing mode, no longer needs pairing to select when selecting sensor for use.
(4) the belt speed pick-up unit directly detects the belt linear velocity, has eliminated the speed detection deviation that various intermediate conversion links are brought.
