In order to solve the above technical problems, to causing the main cause of belt conveyer scale error to carry out comprehensive analysis, concluding
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 it can ignore.The title of one belt conveyer scale use of weighing
Retransmit sensor more, sensor parameters, which are mismatched, can make occur error during material unbalance loading.
The error that B, scale frame are produced：
Scale frame structure has very big relation with error in dipping.Because scale frame is generally steel construction piece, because welding stress and support machine
The deformation of frame in itself can all make scale frame stress change, and cause individual (each）Interfered with each other between fixing point, finally make title
Weight result produces error.This is the bad major reason of belt conveyer scale stability.
C, belt tension influence：
Belt tension mainly has two aspect compositions for belt balance with high precision：
1. belt feeder in order to pull belt operation produce tension force；
2. at belt lacings due to need be bonded thus thus caused joint influence whether belt feeder tension variation this be also
One of influence belt feeder stabilization is than larger factor.
On the basis of being analyzed and researched more than, it is proposed that the online mixing system of belt balance with high precision of the present invention：System master
There are weighing sensor, main belt conveyer scale, point belt conveyer scale, servomotor, servo deceleration machine, special feed bin, discharging opening, weighing and sensing
Device adjustment support composition.Work time-division skin scale is according to setting weight data and collects the speed data of streamline by plc meters
Calculation is transferred to belt conveyer scale to smoothly complete whole work process.
Compared with various prior arts, weighing unit of the invention 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 have
Long-term stability.Because interfering error all between unstable caused by the structural member of weighing platform itself and multi weighing point
It is unstable principal element.Therefore long-time stability difference is always insoluble problem.And the weighing unit single-point of the present invention
Support, i.e., noiseless reason is moved mutually in the absence of the strong point again, so with performance steady in a long-term.Passed with conventional belt
Sensor, which is compared, has two big advantages：1st, offset load resistance is strong --- and same substance is passed at one point sensing device support platform any point
Sensor data measured is equal, therefore it is possible to prevente effectively from influence of the material unbalance loading to weighing on belt.
2. there is simple rational mechanism, it is overall using aluminium alloy extrusions is lightweight, deflection is small, no inherent strain,
Due to weight so can be with the higher side crops industry weighing sensor of choice accuracy.
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.The above can directly be eliminated by the present invention several
The error that individual aspect is brought.
The standardized element that the present invention is used can commercially, and shaped piece is according to specification and accompanying drawing note
Load can carry out customized, specific connected mode use bolt, rivet, welding of maturation etc. in the prior art of each part
Conventional meanses, machinery, part and equipment are using in the prior art, and conventional model adds circuit connection and uses prior art
Middle conventional connected mode, will not be described in detail herein.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit is required rather than described above is limited, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as to the claim involved by limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
