Background technology
The conveying belt of band conveyor (being commonly called as belt) is one of inscape of belt conveyer scale carrier, and states such as the variation of its tension force, the degree of sideslip, speed are all very close for the weighing accuracy relation of belt conveyer scale.
For belt is normally moved, must make belt have suitable elasticity, just to make it keep enough vertical equity tension force.But then, belt is not a rigid body, between adjacent carrying roller group, has sag of chain, so produced the vertical component of tension force, will become the perturbed force to the belt balance weighing sensor.Because the inventory of carrying is taking place to change constantly; The tension force of belt also changes thereupon; Random variation also takes place in the perturbed force for LOAD CELLS, has greatly influenced the weighing accuracy of belt conveyer scale, therefore when the load change of belt, keeps its constant tension constant most important.Because Weight type or trolley type tensioning system the belt conveyer scale (like complete machine type belt conveyer scale) that frame is lacked is inapplicable adopt the spiral tensioning system more, therefore can't realize the automatic adjusting of tension force.
Because in esse all factors, unavoidably can sideslip in the belt operational process, so that the load on the belt conveyer scale carrier will depart from its center line, make sensor receive unbalance loading and reduce accuracy; Also can cause belt conveyer scale normally to move when sideslip is serious.The running deviation value of the rib axle sleeve of 1～2 setting with the restriction belt usually respectively is installed in the belt both sides, but when the frame of belt conveyer scale more in short-term, the installation site of rib axle sleeve is difficult to can have a strong impact on the accurate metering of belt conveyer scale away from weighing length region.
Belt conveyer scale is a kind of dynamic weighing apparatus, its metering to as if its working time in be transferred the cumulative amount of material, so belted electronic balance not only needs LOAD CELLS, also need detect the tachogenerator of material speed or displacement.Belt conveyer scale tests the speed and generally adopts the contact tachogenerator at present.The core of this type sensor is code-disc and change-over circuit, produces pulse signal when code-disc rotates, and code-disc is driven by roller that contacts with belt or changed course roll friction.But the belt contact of roller less (promptly shorter with the belt arc length of contact) is skidded easily, though the cornerite of changed course cylinder big, install comparatively difficulty of code-disc additional.
