Abstract
The utility model relates to an electronic belt scale, in particular an electronic belt scale which is arranged under the belt of the conveyor. The purpose of the utility model is to solve the problem of inaccurate measure when an angle exits for the conveyor. The technical proposal is characterized in that the weighting arm (4) is connected with an end of the weighting sensor (6) through an inferior joint bearing (9); the other end of the weighting sensor is connected with a beam which is arranged on a stander of the conveyor and kept in horizontality, through an upper joint bearing. When an inclination angle exists in the belt of the conveyor, the sensor remains vertical with the horizontal line and only gets pressure from the vertical direction because of the function of the joint bearing. So the pulling force of the sensor is always half of the weight of the object and the direction of the pulling force is parallel to that of the gravity of the object. The utility model has the advantages of reasonable structure and precise measure, and can be used for conveyors with any inclination angle and can improve the measuring precision level.
Description
Technical field: the utility model relates to a kind of belted electronic balance scale frame, particularly is installed in the belted electronic balance scale frame under the conveyer belt.
Background technology: belted electronic balance is widely used in industries such as metallurgy, building materials, chemical industry, electric power, coal, and it is installed in the conveyer belt below, and the bulk material on the conveyer belt is carried out weighing automatically.The belted electronic balance weighing system is by the scale frame that comprises LOAD CELLS, tachogenerator, compositions such as Displaying Meter, wherein the scale frame is generally by weighing carrier roller, sway brace, weighing arm, crossbeam, LOAD CELLS is formed, one end of sway brace is hinged on the frame of conveyer, become fulcrum, the other end is connected with an end vertical fixing of weighing arm, the other end of weighing arm is connected with LOAD CELLS one end vertical hanging, the other end of LOAD CELLS is suspended on the crossbeam, crossbeam is fixed on the frame of conveyer, weighing carrier roller is vertically fixed on the middle part of weighing arm, directly contact travelling belt, the weight of material is delivered to sensor by weighing arm.The scale frame be to gather weight signal as the time spent by LOAD CELLS.The weighing arm of scale frame and belt and crossbeam are arranged in parallel, and when the weighing system was arranged on the conveyor horizontal segment, the tensile force f of sensor was half of weight of material W, i.e. F=W/2.When conveyer belt and surface level have certain inclination alpha, the tensile force f of sensor=Wcos α/2.Owing to introduce the α angle, if microdeformation takes place for scale frame and band conveyor frame, the α angle will be changed, all the stressed of sensor produced a very large impact.Equaling 10 ° with the conveyor inclination angle is example, and there is 0.5 ° of variation at the α angle, will make measuring accuracy produce 0.14% error, and all there is certain inclination angle in the belt feeder major part of practical application, and the problem that error in dipping is big needs to be resolved hurrily.In addition, belt conveyer scale is made of many sensors mostly, must keep the consistance of output, could guarantee measuring accuracy.Sensor is subjected to force direction and gravity direction to have angle, makes sensor be subjected to side force, also will produce certain influence to the measuring accuracy of sensor.
The utility model purpose provides a kind of high-precision electronic belt conveyer scale scale frame, makes sensor and the angle of weighing between the crossbeam changes with the inclination angle of conveyor, guarantees measuring accuracy, solves the problems referred to above that prior art exists.
The utility model content: by two oscillating bearings sensor and weighing arm and crossbeam are coupled together, the hinged quadrature of oscillating bearing can all directions freely rotate, and makes sensor only be subjected to the power of vertical direction, guarantees measuring accuracy.
Adopt the utility model, if conveyer belt is horizontally disposed, weighing arm is parallel with belt, and sensor keeps vertical and is provided with, and vertical with weighing arm, sensor is exported accurate weight signal.If conveyer belt has certain angle of inclination, weighing arm is parallel with belt, also angled with horizontal line, because the effect of oscillating bearing, it is vertical with horizontal line that sensor still can keep, and only is subjected to the power effect of vertical direction, and the tensile force f that always keeps sensor is half of weight of material W, be F=W/2, sensor direction of pull and material gravity direction keeping parallelism.
The utlity model has rational in infrastructure, guarantee characteristics such as measuring accuracy, be applicable to the conveyor at any inclination angle, can improve the measuring accuracy grade.
Description of drawings:
Fig. 1 is a user mode synoptic diagram among the utility model embodiment.
Fig. 2 is sensor and an oscillating bearing structural representation among the utility model embodiment.
Among the figure: conveyer belt 1, material 2, sway brace 3, weighing arm 4, weighing carrier roller 5, sensor 6, crossbeam 7, upper and lower oscillating bearing 8,9 is regulated bolt 10, clamp nut 11.
Embodiment:, further specify the utility model by embodiment below in conjunction with accompanying drawing.
In an embodiment, by sway brace 3, weighing arm 4, weighing carrier roller 5, sensor 6, crossbeam 7, upper joint bearing 8, hypozygal bearing 9, regulate bolt 10, clamp nut 11 is formed the utility model, one end of sway brace is hinged on the frame of conveyer, the other end is connected with weighing arm one end vertical fixing, the other end of weighing arm is connected with LOAD CELLS one end by the hypozygal bearing, the other end of LOAD CELLS is connected with crossbeam by the upper joint bearing, crossbeam is fixed on the frame of conveyer, keep horizontality, weighing carrier roller is vertically fixed on the middle part of weighing arm, directly contact travelling belt 1, the weight of material 2 is delivered to sensor by weighing arm.The weighing arm and the belt of scale frame are arranged in parallel, and when the weighing system was arranged on the conveyor horizontal segment, the tensile force f of sensor was half of weight of material W, i.e. F=W/2.When conveyer belt and surface level have certain inclination alpha, because the effect of oscillating bearing, it is vertical with horizontal line that sensor still keeps, only be subjected to the power effect of vertical direction, the tensile force f that always keeps sensor is half of weight of material W, be F=W/2, sensor direction of pull and material gravity direction keeping parallelism guarantee measuring accuracy.For the belted electronic balance of forming by a plurality of sensors, be provided with on sensor and the oscillating bearing that crossbeam is connected and regulate bolt 10, clamp nut 11, by adjusting bolt and nut, the output of many sensors is kept consistency, improve measuring accuracy.
