Abstract
The invention discloses a multi-idler overall suspension type electronic belt scale weighing device with high weighting accuracy. The weighing device comprises a fixing frame [4], a weighing frame [5], a plurality of weighting idler racks [1] connected with the weighing frame [5] and a plurality of load transfer modules [2] fixedly connected with the fixing frame [4], wherein the fixing frame [4] is fixedly connected with an electronic belt scale support; each weighting idler rack [1] is connected with an idler [6] in a rotating manner; the inside of each load transfer module [2] is provided with a sensor [3] used for weighting the material; and each sensor [3] is connected with the weighing frame [5] to ensure that the weighing frame [5] is suspended on the fixing frame [4], and the bearing surfaces of the sensors [3] and the resultant of the frictional forces of the belt and the idlers [6] are on the same plane. The weighing device has high weighting accuracy.
Description
Technical field
The present invention relates to a kind of electronic belt scale, especially a kind of weighing device of electronic belt scale.
Background technology
It is very extensive that electronic belt scale uses, and is mainly used to convey materials and material is weighed.Belted electronic balance carrier (title frame) is that the loading of belt conveyer scale is born and gravity transfer device, also be first link of weight transfer and conversion in the material weighing process, the good and bad decisive role of the performance of the belted electronic balance of the degree of accuracy of this link and stability.The whole floated title frame of present many carrying rollers is because of its efficient height of weighing, and weighing length is long, and the meter characteristics such as good wave filtering effect to heterogeneous material are widely used.But LOAD CELLS is installed in the certain distance in carrier roller frame below.Belt and carrying roller have produced certain friction force during operation, because the stress surface of this friction force and load sensor has certain distance, so just produced moment of friction, this moment changes along with the weight size of material, thereby influence the stressed of sensor, when belt had certain angle, this moment influence was bigger, so measuring accuracy is subjected to certain influence.
Summary of the invention
Purpose of the present invention is exactly the inaccurate problem of electronic belt scale measuring accuracy that solves the whole floated title frame of existing many carrying rollers, provides a kind of many accurately carrying rollers of weighing whole suspended electronic belt conveyor scale using weighing device.
The technical solution used in the present invention is: the whole suspended electronic belt conveyor scale using weighing device of many accurately carrying rollers of weighing, it comprises fixed frame, weighing frame, be connected in the many groups weighing carrier roller frame on the weighing frame and be fixed in several power transmission modules on the fixed frame, fixed frame and electronic belt scale support are affixed, rotate on the weighing carrier roller frame and be connected with carrying roller, be provided with the sensor that material is weighed in the power transmission module, sensor links to each other with weighing frame, weighing frame is suspended on the fixed frame, it is characterized in that described biography subtracts the making a concerted effort at grade of friction force of device stress surface and belt and carrying roller.
Adopt technique scheme, because the making a concerted effort at grade of the friction force of sensor stress surface and belt and carrying roller, so the friction force of belt and carrying roller is zero to the moment of sensor generation, eliminated the influence of friction force like this.
In sum, beneficial effect of the present invention is: is zero because the present invention, makes friction force by changing the position of sensor to the moment of sensor generation, has eliminated the influence of moment of friction to the belt weighing, has therefore improved the weighing precision that belt claims greatly.

Among the figure, 1, heavy carrier roller frame, 2, the power transmission module, 3, pass and subtract device, 4, fixed frame, 5, weighing frame, 6, carrying roller.
Embodiment
The present invention's whole suspended electronic belt conveyor scale using weighing devices of many accurately carrying rollers of weighing, it comprises fixed frame 4, weighing frame 5, be connected in the many groups weighing carrier roller frame 1 on the weighing frame 5 and be fixed in several power transmission modules 2 on the fixed frame 4, fixed frame 4 is affixed with the electronic belt scale support, rotate on the weighing carrier roller frame 1 and be connected with carrying roller 6, be provided with the sensor 3 that material is weighed in the power transmission module 2, sensor 3 links to each other with weighing frame 5, weighing frame 5 is suspended on the fixed frame 4, and described biography subtracts the making a concerted effort at grade of friction force of device 3 stress surfaces and belt and carrying roller 6.
The present invention is because the friction force of belt and carrying roller 6 makes a concerted effort to be difficult to accurately to determine that general sensor stress surface is a little more than the belt lower surface.
