Description
Technical field
It the utility model is related to a kind of electronic batching scale.
Background technology
Electronic batching scale is commonly called as " burden balance, constant feeder ", belonging to automation equipment again, is that one kind can will by dispensing
Ask, automatically control the proportioner of the dosage of various materials.Electronic batching scale is previously given mass ratio, to by title thing
Several materials carry out batching metering weighing apparatus.In modern industrial production, electronic batching scale has a very wide range of applications, such as
Feed manufacturing, steel-making, production cement etc., are frequently necessary to match somebody with somebody different materials in constant weight ratio in these production procedures
Put carry out hybrid process.Existing electronic batching scale stability and measuring accuracy in actual metered be not high.
The content of the invention
The utility model purpose is to provide a kind of electronic batching scale, and stability is good, and measuring accuracy is high.
In order to realize the above object the technical solution adopted in the utility model is：A kind of electronic batching scale, including scale frame,
Velocity sensor and weighing sensor are provided with scale frame, the side that drive roll is located on scale frame is provided with rotary electric machine and frequency conversion
Device, rotary electric machine and frequency converter are connected with microcontroller, on scale frame on driven voller side setting tensioning apparatus, scale frame
Drive roll position is provided with automatic link code calibration equipment, described velocity sensor includes being arranged at scale frame rear and front end
First, second velocity sensor, vertical hack lever is fixed with support stringer between the stage casing of scale frame is located at two hack levers of scale frame, supports
The stage casing vertical support longeron of longeron is fixed with support Heng Liang, supports Heng Liang projecting end to be fixed on the setting a roof beam in place of scale frame, described
Weighing sensor be arranged at support Heng Liang on.
It is of the present utility model to have technical effect that：Burden balance are automatically controlled by microcontroller according to setting to run.Adopt
With the front and rear velocity sensor of two-speed sensor first, second, sensing haul speed, so test the speed more accurate.This practicality is new
Type weighing sensor uses parallelogram weighing sensor, is avoided that between belt and roller horizontal force caused by friction to burden balance
The influence of precision.And weighing sensor is arranged on support Heng Liang, support Heng Liang one end and scale the frame connected, other end of setting a roof beam in place lead to
The hack lever for crossing support stringer and scale frame is connected, and the weighing sensor being arranged so as to relies on the stable construction of scale frame itself, and arrangement is more
Add stabilization.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to the drawings, a kind of electronic batching scale, including scale frame 1, velocity sensor 2 and weighing and sensing are provided with scale frame 1
Device 3, the side on scale frame 1 positioned at drive roll 4 are provided with rotary electric machine 5 and frequency converter 6, rotary electric machine 5 and frequency converter 6 and micro-control
Device MCU7 connections processed, tensioning apparatus 9 is set positioned at the side of driven voller 8 on scale frame 1, is provided with scale frame 1 close to the position of drive roll 4
Automatic link code calibration equipment 10, first, second speed that described velocity sensor 2 includes being arranged at the rear and front end of scale frame 1 pass
Sensor 2a, 2b, vertical hack lever is fixed with support stringer 11, support stringer 11 between the stage casing of scale frame 1 is located at two hack levers of scale frame 1
Stage casing vertical support longeron 11 be fixed with support weighing apparatus beam 12, the projecting end of support weighing apparatus beam 12 is fixed on the setting a roof beam in place of scale frame 1, institute
The weighing sensor 3 stated is arranged on support weighing apparatus beam 12.
Burden balance are automatically controlled by microcontroller 7 according to setting to run.Using front and rear two-speed sensor 2 first,
Second speed sensor 2a, 2b sense haul speed, so test the speed more accurate.The utility model weighing sensor 3 is using flat
Row quadrangle weighing sensor, it is avoided that influence of the horizontal force to burden balance precision caused by friction between belt and roller.And it will claim
Retransmit sensor 3 to be arranged on support weighing apparatus beam 12, support the weighing apparatus one end of beam 12 and scale the frame 1 connected, other end of setting a roof beam in place pass through support stringer
11 are connected with the hack lever of scale frame 1, and the weighing sensor 3 being arranged so as to relies on the stable construction of scale frame 1 itself, and arrangement is more steady
It is fixed.Automatic link code calibration equipment 10 is arranged on the lower position of burden balance scale frame 1, by electric control gear automatic lifting roller code or link code,
Roller is fallen during verification（Hang）Code, makes roller（Hang）Code automatic steady press on scale frame 1, simulate homogeneous material by, to
The precision and stability of burden balance is examined, at the end of verification, roller can be risen automatically（Hang）Code, receive to original position, it is accurate to complete burden balance
The verification of exactness.
Further, the beam-ends of support stringer 11, which is provided with, strengthens steel plate 13, and described reinforcement steel plate 13 is embedded in scale frame 1
Hack lever in fixed and arranged.By strengthening the stable arrangement between the reinforcement support stringer 11 of steel plate 13 and scale frame 1, and then further
Ensure the stable arrangement of weighing sensor 3.
Further, the haul direction of scale frame 1 is provided with multiple weighing sensors 3.The multiple weighing and sensings set
Device 3 reaches the multi-faceted detection of weighing to haul on scale frame 1, further reduces error in dipping.
In addition, the utility model burden balance scale frame 1 uses direct-loading scale frame structure, that is, carrying of not weighing
Device, this scale frame 1 is easy to maintenance, does not have balance pivot on scale frame 1, without movable member, the problem of abrasion in the absence of fulcrum.Directly
Connect that loading scale frame size is short and small, the surface area of horizontal direction is small, and dust stratification amount is small, and dust stratification causes Zero change small, without frequent
Clean.Direct bearing type scale frame structure ensure that the weight of material is applied directly on weighing sensor 3, and very simply, weight is also very
Gently.
