Description
Technical field
The invention belongs to batching weighing equalizer technology field, more particularly, to a kind of many belt speed governing scales of suspension type.
Background technology
Speed governing scale has been widely used for the dynamic weighing of material, its according to lever principle, under the belt for continuously running
Leverage is installed in face, and the loading end of lever is then several drum apparatus, walks out-of-date reduction belt above for meeting belt
The error in dipping caused with the friction of loading end.Metering section has also got rid of traditional sliding weight of steelyard device simultaneously, and using utilization
The LOAD CELLS of strain resistor manufacture is being measured.
Speed governing scale is suitable for carrying out various pieces, granular material continuous conveying, feed control and dynamic weighting, can be extensive
The industries such as cement, metallurgy, chemical industry, grain are applied to, accurate continuous data and reliable control are provided to commercial production and management
Means processed.Common are electronic speed-adjusting weigher and frequency conversion type speed governing scale etc..Wherein, the operation principle of frequency control belt conveyer scale is:Weight
Belt speed signal that the output of force transducer stress gravitational cue and tachogenerator side go out is conditioned and digitized processing after, by
Controller carries out multiplication and quantum chemical method, draws instantaneous delivery and cumulative amount on belt conveyer scale, while controller is by instantaneous delivery
It is compared with specified rate and draws deviation, according to deviation controlled output value, quite device is become by output valve control, by converter control
Motor speed processed, changes the linear velocity of belt, so that instantaneous delivery convergence specified rate, realizes the purpose of dosing.
In prior art, the scale frame of belted electronic balance is mostly using single carrying roller Cross-shape Plate Spring supporting structure, the scale of this structure
Frame by belt tension change and kinestate change affected larger, when weigh carrying roller on bondd material or dust when, can send out
The riempie phenomenon such as sideslip, bounce in operation, when the tension force of belt is affected by ambient temperature, humidity and is changed,
Instrument zero point can be caused to be continually changing, these factors will all have a strong impact on the degree of accuracy of weighing, the scale body of belt conveyer scale is longer, these
Phenomenon is just more difficult to overcome.If in addition, belt is aging, will also result in measuring accuracy step-down.
Content of the invention
The purpose of the present invention is to overcome deficiency of the prior art, improves the measuring accuracy of speed governing scale.
For reaching above-mentioned purpose, the invention provides a kind of many belt speed governing scales of suspension type.The speed governing scale includes that belt drives
Dynamic device, support, scale frame, multiple gravity sensors, multiple pressure transducers and multiple velocity sensors, and double belts, institute
Stating support includes that upper bed rack and lower layer frame, the plurality of velocity sensor are fixed on the lower floor of support, and the scale frame sets
Put on the plurality of velocity sensor, and scale frame is hung under the upper bed rack of support, the belt drive drives
In material carriage direction, double belts, described pair of belt include that first pair of belt and second pair of belt, wherein first pair belt are laid
Between the scale frame and the plurality of gravity sensor and multiple velocity sensors, second pair of belt is laid in and props up
On the upper bed rack of frame, and second pair arranges the plurality of gravity sensor between belt and upper bed rack.
Further, scale frame adopts rubber hanger, vibration proof.
Further, using Japanese big and LOAD CELLS, waterproof and dustproof, (with temperature difference automatic compensation function) metering
Precision：0.015%.
The invention has the beneficial effects as follows ensure that many belt speed governing scales remain to timely be tieed up in use for some time
Shield, is unlikely to make precise decreasing because of the factor such as aging, and the reason for be easy to keep in repair and search precise decreasing caused by belt.
Description of the drawings
Fig. 1 shows the structural representation of many belt speed governing scales of suspension type.
Specific embodiment
Elaborate below in conjunction with the accompanying drawings.Structural representation as shown in Figure 1, many belt speed governing scales of suspension type include skin
Band driving means (motor, not shown), support 1, scale frame 2, multiple gravity sensors 3, multiple pressure transducers 5 and multiple speed
Sensor (not shown), and double belts, the support include that upper bed rack and lower layer frame, the plurality of velocity sensor are fixed
On the lower floor of support 1, the scale frame 2 is arranged on the plurality of velocity sensor, and scale frame 2 hangs on support 1
Under upper bed rack, the belt drive drives double belts, described pair of belt to include first pair of belt in material carriage direction
With second pair of belt, wherein first pair belt be laid in the scale frame 2 and the plurality of gravity sensor 3 and multiple speed
Between sensor, second pair of belt is laid on the upper bed rack of support 1, and second pair is arranged between belt and upper bed rack
The plurality of gravity sensor 3.The advantage of this structure of the present invention is：The pressure measured using second pair of belt on upper bed rack
Force value (is actually pressure value), whether can more accurately obtain first pair of belt (i.e. dispensing transport band) in lower layer frame
Aging or be affected tension force because being infected with the factor such as dust.
Tread speed sensor direct detection belt linear velocity, eliminates the velocity measuring that various intermediate conversion links are brought
Deviation.
The structure of of the invention some specific embodiments is illustrated in the way of word and description of the drawings above, and non-exhaustive
Nothing left is limited to concrete form described above.It should be pointed out that for those skilled in the art, do not taking off
On the premise of the principle of the invention, some improvements and modifications can also be made, these improvements and modifications also should be regarded as the present invention's
Protection domain.
