Abstract

The utility model discloses an electronic belt scale which comprises a hopper (5), a small burdening belt (4) positioned below the hopper (5), a frequency converter (1) electrically connected with a driving motor (6) and conducting frequency conversion and speed regulation on the driving motor (6), and a belt scale instrument (3), and is characterized by also comprising a voltage/frequency converter (2), wherein an output terminal of the frequency converter (1) is electrically connected with an input terminal of the voltage/frequency converter (2), and an extending terminal of the voltage/frequency converter (2) is electrically connected with the belt scale instrument (3), so that the rotating speed of the small burdening belt (4) can be directly displayed on the belt scale instrument (3) through the current frequency. The electronic belt scale is accurate in speed measurement without being influenced by the external environment.

Description

A kind of belted electronic balance
Technical field
The utility model relates to a kind of belt that is provided with speed measuring device and claims, exactly is that a kind of belt that tests the speed through frequency conversion is claimed.
Background technology
Belt is claimed to be widely used on the commercial production material being weighed.Belt often claim in transmission material process needs confirm feeding quantity in the unit interval how much, with this feeding quantity in explained hereafter is controlled.The speed measuring device that belt commonly used is claimed in the production mainly contains two kinds of modes, and a kind of is " contact ", and speed sensors is installed, and directly tests the speed through sensor; Another kind is " contactless ", promptly Hall element is installed or reducer gear tests the speed, and the drawback of two kinds of speed measuring devices is: because installing component all at the scene; And on-the-spot environment is more abominable; Artificial many with unartificial factor, the part that tests the speed often suffers damage, and beats like gear; The electromagnetic induction device is loosening, will cause test the speed inaccurate, thereby influence proportioning accuracy, if field management is not in place, feed proportioning system is possibly so can't normally move.
The utility model content
The purpose of the utility model solves the existing belt inaccurate problem of claiming to test the speed exactly, provides a kind of belt that has the frequency conversion speed measuring device to claim.
The technical scheme that the utility model adopts is: a kind of belted electronic balance; It comprises hopper, be positioned at the batching belt lace of hopper below, be electrically connected frequency converter and belt that drive motor is carried out frequency control with drive motor claims instrument; It is characterized in that it also comprises electric voltage/frequency converter; An output terminal of frequency converter is electrically connected with the input end of electric voltage/frequency converter; The external part of electric voltage/frequency converter claims that with belt instrument is electrically connected, and makes to claim the rotating speed that instrument directly shows the belt lace of preparing burden through the frequency of electric current from belt.
Adopt technique scheme; During use, because the rotating speed of drive motor and the frequency of electric current are in direct ratio, when frequency converter output voltage passes through electric voltage/frequency converter; Can record the frequency of belt drives electric moter voltage; Because the frequency and the belt drives motor speed of motor are in direct ratio, therefore can show rotating speed of motor through instrument, also just record the rotating speed of batching belt lace.
In sum; The utility model beneficial effect is: because the speed measuring device of the utility model does not directly contact with the batching belt lace; Can place the speed measuring device of the utility model environment preferably in the pulpit like this, so external environment influence be little, tests the speed through the electric voltage frequency conversion simultaneously; Speed measuring device is not fragile, so the utility model tests the speed accurately.

Embodiment
A kind of belted electronic balance of the utility model; As shown in Figure 1; It comprises hopper 5, be positioned at the batching belt lace 4 of hopper 5 belows, be electrically connected frequency converter 1 and belt that drive motor 6 is carried out frequency control with drive motor 6 claims instrument 3; It also comprises electric voltage/frequency converter 2; An output terminal of frequency converter 1 is electrically connected with the input end of electric voltage/frequency converter 2, and the external part of electric voltage/frequency converter 2 claims that with belt instrument 3 is electrically connected, and makes to claim the rotating speed that instrument 3 directly shows batching belt lace 4 through the frequency of electric current from belt.
