Abstract
The utility model provides a suspension type electronic belt weighing device, comprising a frame, a feeding belt machine and a belt balance which are arranged on the frame. The utility model is characterized in that: the feeding belt machine and the belt balance are formed into a butt joint by a feeding board. The belt balance fully suspends on the frame by pressure sensors which are distributed over the four corners below the belt balance. Furthermore, the protective supports are arranged beside the pressure sensors. A driving motor dynamic shaft is directly connected with the active roller shafts of the output ends of the feeding belt machine and the belt balance. Fundamentally, the utility model overcomes the shortages of low measuring accuracy, complicated structure and inconvenient operation of the prior electronic belt weighing device. The utility model increases the symmetry and the equilibrium of the weighing table. The utility model eliminates the angle difference of the balance table and makes the force-response curves of the sensors present the horizontal lines completely. Consequently, the utility model is free from the effects of the material eccentric load, the belt deviation and the lateral force. The utility model can protect the sensors and ensure the accurate prescription. The utility model is an electronic belt weighing device with low cost, high measuring accuracy and compact complete-machine structure actually.
Description
Technical field
The utility model relates to a kind of belted electronic balance, especially a kind of suspended electronic belt conveyor scale using of finishing dynamic measurement in course of conveying simultaneously.
Background technology
Loose unpacked material needs to carry out dynamic measurement in course of conveying, to control mass flow or to carry out the assembly of various materials.Existing dynamic measurement belted electronic balance exists complex structure, adjustment and proofreads deficiencies such as trifling numerous and diverse again, function singleness, measuring accuracy difference, particularly measuring accuracy is low is to need a difficult problem of capturing for a long time, and the factor that influences measuring accuracy is varied, all directly affects the measuring accuracy of belt conveyer scale as distribution of the flatness of the size of material drop, belt tension, material unbalance loading, conveying belt, side force, mechanical friction point, sensor etc.Chinese patent 02216680.7 discloses " a kind of floated pair of belt conveyer scale ", and this belt conveyer scale is made of feeder hopper, belt feeder, belt conveyer scale etc.For reducing the impact that the material drop causes to belt conveyer scale greatly, the belt feeder of this machine and belt conveyer scale all adopt big, the driven cylinder of drive roll little, and with the mode of carrying roller back-up belt, and the layout of sensor below belt conveyer scale is three points.The drawback that this frame mode brought is that Panasonic is tight on the belt conveyor, add the effect of upper supporting roller, cause the out-of-flatness and the vibration of band big, 3 layouts that add upper sensor, in conveying, metering process, very easily influence the measuring accuracy of belt conveyer scale, simultaneously material is spilt from the junction, soft limit of both sides, thereby influence the prescription of material, finally cause product quality to descend.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of measuring accuracy height is provided, the weighing platform good stability, and no blanking impacts, and friction is adjusted, check and correction is simple and convenient, can protect the suspended electronic belt conveyor scale using of sensor.
The utility model is realized by following technical proposal: a kind of suspended electronic belt conveyor scale using; comprise frame; place belt feeder and belt conveyer scale on the frame; it is characterized in that belt feeder and belt conveyer scale connect by stock guide; belt conveyer scale is suspended on the frame by the pressure transducer on four angles that distribute thereunder entirely; and be provided with protective cradle on the pressure transducer side, the drive motor line shaft directly links to each other with the drive roll axle of belt feeder and belt conveyer scale output terminal.
Both sides, belt feeder end are fixed or be movably arranged on to described stock guide one end, and the soft limit tower of the other end by its port is connected on the belt conveyer scale scale face, overcoming the impact of blanking difference to belt conveyer scale, the soft tower of stock guide and scale face connects and does not influence its accurate measurement simultaneously.
The other protective cradle of four pressure transducers in described belt conveyer scale below is liftable cylinder or screw rod; it is separately fixed on belt conveyer scale below and the frame at two ends up and down; fall this lifter during work; belt conveyer scale is suspended on the pressure transducer entirely, guarantees measuring accuracy, rise this lifter when not working; belt conveyer scale is supported thereon; the infringement of avoiding human factor or other factors that pressure transducer is caused reduces the workload of adjusting, proofreading pressure transducer simultaneously, increases work efficiency.
The support bar of described belt feeder is fixed bar or is adjustable height and/or the adjustable movable support rod of level, so that require to adjust the height of belt feeder or/and horizontal level according to operation field.
The utility model compared with prior art has following advantage and effect: adopt such scheme; it is big because of material impacts fundamentally to have overcome existing belted electronic balance; the feeding out-of-flatness; drive roll is located at input end; sensor irrational distribution and the measuring accuracy brought is low; complex structure; operate the loaded down with trivial details deficiency that waits; especially the setting of stock guide achieves a butt joint belt feeder and belt conveyer scale; eliminated the impact of material to weighing platform; the layout at pressure transducer four angles below belt conveyer scale has enlarged the carrying plane of feed track and material; increased the symmetry of weighing platform; balance; eliminate the weighing platform angular difference; make the force-responsive curve of sensor be entirely horizontal linear; thereby be not subjected to the material unbalance loading; the influence of belt deviation and side force; being provided with of protective cradle has protective effect to sensor simultaneously; make it can be not impaired; need not during work to adjust everyday; the school scale; drive roll makes conveying belt tighten pine down in the setting of output terminal; advantages of higher stability and planarization have been kept; material can be flexible coupling from scale face and two side shields to be spilt; guarantee that this weighing-appliance has higher measuring accuracy; for the accurate prescription of postorder material provides reliable guarantee; motor is installed on the drive roll axle in addition; directly driving drive roll rotates; both saved various gear train; reduce cost; make compact integral structure again; therefore, be that an ideal is practical in fact; the belted electronic balance that measuring accuracy is high.
