Description
Technical field
The present invention relates to a kind of method of measuring material conveying instant speed of exit of screw feeder, belong to Weighing type conveyor technical field.
Background technology
The speed measuring device that is extensive use of at present helical feed computation weigh system normally adopt gather the drive motor rotating speed as measuring parameter to determine material movement speed.Because mainly by the promotion of blade, material itself not only will overcome the friction force of cylindrical shell in the motion of material in the screw feeder, simultaneously at the motion or the generation movement tendency radially that radially also can produce radially because of friction with blade.Material comprises water cut in addition, the character of itself is not constant homogeneous, therefore the material in the screw machine cylindrical shell is actually and is doing very complicated variable motion, and weighing measurement requirement collection is the axial velocity of material output cylindrical shell instantaneous time, moment axial velocity when the rotating speed of therefore gathering drive motor can not show material output as measuring parameter, this makes metering produce very mistake, symmetry remakes very big influence, for addressing this problem, need real-time measurement be arranged to the instantaneous velocity of the material axially-movable of cylindrical shell outlet.
Summary of the invention
The purpose of this invention is to provide a kind of method of measuring material conveying instant speed of exit of screw feeder
For realizing above purpose, technical scheme of the present invention provides a kind of method of measuring material conveying instant speed of exit of screw feeder, it is characterized in that, adopts gear to test the speed, and its method is:
The first step. the gear shaft support is fixed on the afterbody cylindrical shell below of weighing type spiral batcher, gear shaft is installed on the gear shaft support, measure speed gears is installed on the gear shaft, and the feeding cylindrical shell is stretched in its upper part, makes the measure speed gears down motion of drive of material at the volley;
Second step. an end of grating encoder is connected with gear shaft, and the other end is connected with Displaying Meter; Or magnetic survey speed probe is installed in the measure speed gears end portion over against teeth groove, magnetic survey speed probe is connected with Displaying Meter;
The 3rd step. start the weighing type spiral batcher, material in the cylindrical shell drives the measure speed gears motion of barrel front end bottom, gear driven grating encoder in the motion produces pulse signal as metering signal, show by Displaying Meter, or the magnetic field of a variation of magnetic survey speed probe formation, by magnetic survey speed probe the electric signal that this field signal is converted into variation is shown by Displaying Meter.
The present invention adopts gear to test the speed, other movement velocitys influences that radially reach of the material of compound movement are eliminated, only gather axially-movable speed, when the material in the cylindrical shell is carried vertically, although material has irregular movement or trend, the output but material always can move vertically, therefore allow the material web moving gear of axially-movable rotate thereupon, thereby make the irregular movement of material in the cylindrical shell change into the linear movement of gear rule, by grating encoder or magnetic survey speed probe the mechanical signal of gear movement is converted into again that the electric signal of variation is convenient to use various measurement means to carry out the measurement of speed.
Advantage of the present invention is to adopt the gear mechanism distortion of testing the speed little, can measure the material instantaneous velocity immediately exactly.
