The operation principle of present embodiment is：Can be with a belt conveyer scale real-time and precise feed or more belt conveyer scale groups
Close real-time and precise and be fed in main belt feeder or container and reach synchronous uniformly batch mixing purpose.Belt conveyer scale can be according to touch-screen institute
The different feed real-time accurate feedings of part by weight are set, while the flowing water linear velocity that can be gathered by encoder is fast according to speed
Slow different adjust automatically feeding speeds reach synchronous accurate feeding demand in real time.Belt balance with high precision of the present utility model mixes online
Weighting error caused by self structure and belt tension can be completely eliminated in material unit and combined system of weighing, so as to reason
The measuring accuracy thought, and stability is good, can keep measuring accuracy for a long time, mechanism is simple in addition, cost economy, installation and debugging
Easy to use, maintenance workload is few, and service life length, the labor intensity for greatly alleviating worker has wide applicability.
In order to solve the above technical problems, the main reason for causing belt conveyer scale error has carried out comprehensive analysis, conclude
Go out the error of belt conveyer scale essentially from following three aspect：
A, weighing sensor and computer instrument：
Due to the development of sensor apparatus technology, error very little.Substantially can ignore.One belt of weighing scale uses
Weighing sensor it is more, sensor parameters mismatch can make error occurs during material unbalance loading.
B, error caused by scale frame：
Scale frame structure has very big relation with error in dipping.Because scale frame is mostly steel construction piece, because welding stress and branch
The deformation of support frame in itself can all make scale frame stress change, and cause individual (each）Interfered with each other between fixing point, finally
Weighing results are made to produce error.This is the bad major reason of belt conveyer scale stability.
C, the influence of belt tension：
Belt tension mainly has two aspects to form for belt balance with high precision：
1. belt feeder in order to pull belt run caused by tension force；
2. at belt lacings due to need be bonded thus thus caused joint influence whether belt feeder tension variation this
And influence a stable bigger factor of belt feeder.
On the basis of being analyzed and researched more than, it is proposed that the online mixing system of the utility model belt balance with high precision：This is
System mainly has weighing sensor, main belt conveyer scale, divides belt conveyer scale, servomotor, servo deceleration machine, special feed bin, discharging opening, weighs
Sensor adjustment support composition.Work time-division skin scale passes through according to setting weight data with the speed data for collecting streamline
Plc is calculated and is transferred to belt conveyer scale so as to smoothly complete whole work process.
Compared with various prior arts, weighing unit of the present utility model has following mechanical feature：
1. a weighing unit has one to be no more than two strong points of weighing, not only structure simplifies, it is often more important that
With long-term stability.Because interfere mistake between unstable caused by the structural member of weighing platform itself and multi weighing point
Difference is all unstable principal element.Therefore long-time stability difference is always insoluble problem.And of the present utility model weigh
Unit single-point support, i.e., noiseless reason, is moved mutually in the absence of the strong point again, so having performance steady in a long-term.With commonly using
Belt sensor compared to having two big advantages：1st, offset load resistance is strong --- and same substance is appointed in one point sensing device support platform
A point sensor data measured of anticipating is equal, therefore it is possible to prevente effectively from influence of the material unbalance loading to weighing on belt.
2. with simple rational mechanism, it is overall using aluminium alloy extrusions is in light weight, deflection is small, without inherent strain,
So can be with the higher side crops industry weighing sensor of choice accuracy due to weight.
Analysis is, it is known that belt weighing error is mainly derived from weighing structure and belt tension more than.Improvement is weighed
Structure thoroughly eliminates the error that belt tension is brought to high precision belt machine simultaneously.By the utility model can directly eliminate with
The error that upper several aspects are brought.
The standardized element that the utility model uses can commercially, shaped piece according to specification and accompanying drawing
Record can carry out customized, the specific connected mode of each part is using bolt ripe in the prior art, rivet, weldering
The conventional meanses such as connect, machinery, part and equipment are using in the prior art, conventional model, plus circuit connection using existing
Conventional connected mode, will not be described in detail herein in technology.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
