Abstract
The utility model relates to an electronic belt scale with a suspended scale rack. The electronic belt scale is widely used for the continuous dynamic weighing and measuring of bulk materials. The utility model is characterized in that the electronic belt scale is provided with a suspended scale rack; a horizontal limiting spring strip is arranged between the scale rack and a fixing bracket. The suspended scale rack is mainly composed of a loading bolt, an adjusting bolt, a loading member, a weighing supporting roller, a supporting roller rack, a sensor, etc. The electronic belt scale has the advantages of high weighing precision, simple structure, reliable work, convenient installation, debugging, use and maintenance, etc.
Description
The utility model relates to a kind of belted electronic balance, and it has floated scale frame, is widely used in the continuous Dynamic Weighting of bulk cargo.
At present, the belted electronic balance scale frame that generally adopts has rubber gudgeon fulcrum, double lever type, no counterweight, many roller-types.From weighing principle, belted electronic balance is to convert the weight of material on the belt to electric signal through sensor and other instrument, shows at last.Obviously in signal transduction process, many conversion links will have more existing transformed error.The transformed error of belted electronic balance is mainly from the scale frame, for the scale frame of band fulcrum and lever, because of the effect of the process central bearing point that transmits power and the lever transmission error of exerting all one's strength bigger.Because all there is inertia in any lever system, all can produce hysteresis error and reproducibility error; Any lever system all exists the arm of force and lever ratio, so when not simultaneously by the application point of dynamometry, the suffered real load of its sensor will be different, thereby cause the power transmission error, in addition, because lever system is a balanced system, when certain reason (as dust stratification, vibrate, snap in foreign matter etc.) causes former balance destroyed, will be offseted (or increase) part by dynamometry, thereby produced the distortion of measuring.Usually the environment of belted electronic balance work often all compares badly, has many factors that causes above-mentioned error, therefore has the scale frame of fulcrum and lever to have very big weak point.
In view of the problems referred to above that exist, the purpose of this utility model is to design a kind of weighing precision height, and is simple in structure, reliable operation, installation, debugging, use, a kind of belted electronic balance with floated scale frame easy to maintenance.
For achieving the above object, the technical measures that the utility model is taked are: 1]. the belted electronic balance with floated scale frame is by head cylinder (1), dust cover (2), belt frame (3), scale frame (4), fixed support (6), hopper (7), afterbody belt tensioning drum (8), motor--reductor (9), belt (10) is formed, wherein scale frame (4) adopts floated scale frame, and it is by counterweight frame (11), loading bolt (12), adjust bolt (13), loaded members (14), weighing carrier roller (15), carrier roller frame (16), sensor (17), sensor base (18), sensor stand (19) is formed.2]. between scale frame (4) and fixed support (6), horizontal position-limiting spring leaf (5) is set.
The good effect that the utility model produces is: owing to take above-mentioned measure, the weighing error of belt conveyer scale is significantly reduced, and the weighing precision height, simple and reasonable, reliable operation, installation, debugging, use, easy to maintenance.
Introduce structure, principle of operation and the process of the belted electronic balance of the floated scale frame of the utility model band in detail below in conjunction with accompanying drawing.
Fig. 1 is the one-piece construction figure with the belted electronic balance of floated scale frame.
Fig. 2 is the structural representation of floated scale frame.
As shown in Figure 1, with the belted electronic balance of floated scale frame by head cylinder (1), dust cover (2), belt frame (3), scale frame (4), horizontal position-limiting spring leaf (5), fixed support (6), hopper (7), afterbody belt tensioning drum (8), motor--reductor (9), belt (10) are formed.
As shown in Figure 2, scale frame (4) adopts floated scale frame, and it is made up of counterweight frame (11), loading bolt (12), adjustment bolt (13), loaded members (14), weighing carrier roller (15), carrier roller frame (16), sensor (17), sensor base (18), sensor stand (19).
Only experience the signal power of vertical direction in order to make sensor (17), be not subjected to the perturbed force of horizontal direction, horizontal position-limiting spring leaf (5) can be connected between scale frame (4) and the fixed support (6), utilize big rigidity on its large deflection, little rigidity and the horizontal direction to realize retraining the horizontal shift of carrier roller frame (16), also can not influence the displacement of its vertical direction simultaneously in vertical direction.
Because the material on the belt (10) is taken back sometimes or is taken over, in order to eliminate because of the uneven uneven loading error that causes of cloth, so respectively establish a sensor (17) together with two subfacieses of carrier roller frame (16) at weighing carrier roller (15), secondary instrument is all got two signal of sensor sums like this, weighing precision is improved, also be convenient to simultaneously loading and unloading and maintenance, easy to use.
This principle of operation and process with the belted electronic balance of floated scale frame is: when belt (10) is gone up by material, the weight of material acts on weighing carrier roller (15) and the carrier roller frame (16) through belt (10), act on the sensor (17) through adding article carrying piece (14) and loading bolt (12), the output signal sum of two sensors (17) shows behind secondary instrument again.Owing on the transfer route of power, do not have rotatable parts and movable part, therefore realized directly weighing.
Claims (2)
1, a kind of belted electronic balance with floated scale frame, it is by head cylinder (1), dust cover (2), belt frame (3), scale frame (4), fixed support (6), hopper (7), afterbody belt tensioning drum (8), motor--and reductor (9), belt (10) are formed, and it is characterized in that:
1]. scale frame (4) adopts floated scale frame, and it is made up of counterweight frame (11), loading bolt (12), adjustment bolt (13), loaded members (14), weighing carrier roller (15), carrier roller frame (16), sensor (17), sensor base (18), sensor stand (19);
2]. between floated scale frame (4) and fixed support (6), be fixed with horizontal position-limiting spring leaf (5).
2. the belted electronic balance with floated scale frame according to claim 1, it is characterized in that sensor (17) respectively the weighing carrier roller (15) in scale frame (4) respectively establish one together with two below the carrier roller frame (16).
