Abstract
The utility model provides a slide plate electronic scale, which can continuously and dynamically weigh movable materials in production operation. The utility model uses a sloping rigid slide plate (1) to make materials which are measured slide downwards along a baffle plate (2) to form continuous material flow. The rigid slide plate (1), a force transmission rod (2), a force sensor (4), and a supporting frame (5) are all connected in rigidity. Compared with belt electronic scales, the utility model cancels a movement mechanism, and thus, the utility model has the advantages of higher and stable measuring accuracy and simple structure, and the utility model avoids regular maintenance regulation and material consumption.
Description
The utility model relates to a kind of to material metage, particularly moving bulk, graininess and powder material in the production operation is carried out the dynamic device of weighing continuously and being transformed into corresponding electric signal.
On the production line of industries such as metallurgy, mine, building materials, grain, often need carry out dynamic weighing to solid block, graininess and powder material, promptly weight of material is transformed into corresponding electric signal, calculates the data such as flow, semi-invariant of tested material then by microcomputer or instrument with measurement mechanism.The dynamic weigher that generally uses is a belt scale at present.The measuring accuracy of belt scale is except that being subjected to used sensor accuracy influences, also there is such problem in use, promptly, belt do not cause the easy sideslip of belt because not stopping transport to move, load variations and temperature variation cause the belt tension change and cause the belt speed instability, these factors all directly have influence on the accuracy of measurement, and this influence surpasses the influence of sensor accuracy to measuring, and in order to keep measuring accuracy, just must often regulate correction; Therefore in addition, belt scale has motion, certainly exists wearing and tearing, must be lubricated, daily servicing operations such as renewal part, adjustment.
The purpose of this utility model be to provide a kind of can the kinetic measurement weight of material and can be converted into the device of electric signal, it can solve the problem that is caused the measuring accuracy reduction by measurement mechanism motion itself.
The purpose of this utility model is achieved in that the supporting body of making measured material with a rigid plate-like metal material, this rigid plate (1) is arranged to play the slide plate effect horizontal by an angle, rigidity slide plate both sides have baffle plate (2), and this baffle plate can be that same material forms through bending with the rigidity slide plate.The rigidity slide plate is fixed on the transmission rod (3).Transmission rod is fixed on the force side of force transducer (4).Force transducer is installed on the bracing frame (5).Above-mentioned be connected and fixed to be rigidly connected, this connection makes and keeps relative static state between rigidity slide plate and bracing frame, when being subjected to normal external force, the rigidity slide plate does the time spent, small elastic deformation only takes place in parts such as rigidity slide plate, transmission rod, force transducer, and the motion with respect to bracing frame does not take place.Rigid connection method can adopt methods such as bolt, welding, riveted joint.When charging gear on the rigidity slide plate during feed, material is subjected to action of gravity and glides along the baffle plate direction, forms continuous streams.By physics knowledge as can be known, the weight of material linear dependence of the acting force that the rigidity slide plate is subjected to and its carrying, the vertical stress component of this acting force is delivered to the force side of force transducer through transmission rod, and force transducer is transformed into corresponding electric signal to vertical stress component for microcomputer or instrument sampling.Microcomputer or instrument can be selected for use commercially available for weighing supporting product, as Shanghai greatly with the relevant product of electronic scale company.
Material supporting body material and one-piece construction that the utility model adopts are different fully with existing belt scale.The rigidity sliding material is made with metal, is better than elastomeric material serviceable life.There are not the required balanced controls of belt scale in the device; There is not the necessary motion of belt scale in the device, thus not only simple in structure, and exempted daily maintenance work and material consumption.Owing to do not have the adverse effect of motion own, so measuring accuracy of the present utility model is main relevant with sensor accuracy, so measuring accuracy is higher and stable than belt scale to measuring accuracy.
Below the utility model is described further.
Fig. 1 is a synoptic diagram of the present utility model.
This slide plate electronic scales device comprises a rigidity slide plate (1), rigidity slide plate both sides have baffle plate (2) rigidity slide plate to be rigidly connected by transmission rod (3) and force transducer (4), force transducer is rigidly attached to above the bracing frame (5), rigidity slide plate and horizontal plane angle are the 35-55 degree, and the rigidity slide plate is relative static with bracing frame.
When the charging gear on the production line (6) during to slide plate electronic scales feed, material drops on the upper surface of rigidity slide plate (1) and glides along the direction of baffle plate (2) and forms streams (7), material is delivered to force transducer (4) to the vertical stress component of rigidity slide plate acting force by transmission rod (3), force transducer is transformed into corresponding electric signal to detected vertical stress component through cable (8) output, for microcomputer or instrument sampling.Because streams is continuous, so the utility model can be realized the continuous detection of dynamic of weight of material and be transformed into corresponding electric signal.
Claims (3)
1, to material metage, particularly to moving bulk in the production operation, the slide plate electronic scales device that graininess and powder material are weighed continuously, the feature of this device is, make the supporting body of measured material with a rigid plate-like metal material, this rigid plate (1) is arranged to play the slide plate effect horizontal by an angle, rigidity slide plate both sides have baffle plate (2), the rigidity slide plate is fixed on the transmission rod (3), transmission rod is fixed on the force side of force transducer (4), force transducer is fixed on the bracing frame (5), above-mentioned be connected and fixed to be rigidly connected, this connection makes and keeps relative static state between rigidity slide plate and bracing frame, when being subjected to normal external force, the rigidity slide plate does the time spent, the rigidity slide plate, transmission rod, small elastic deformation only takes place in parts such as force transducer, and the motion with respect to bracing frame does not take place.
