Description
Technical field
The utility model relates to a kind of for detecting the device of roller-crushing mill powder machine bin-level, belong to detection technique field.
Background technique
When roller-crushing mill powder machine is run, Ultramicro-powder enters flour mill feed bin by the efficient plansifter of upper part, then at two
Opposite grinding roller gap crushes.When lacking material in feed bin, it just will appear between grinding roller and be mutually twisted, cause grinding roller odontotripsis, finally lead
It causes grinding roller mechanical damage occur, influences the normal service life of grinding roller.In order to extend the service life of grinding roller, roller-crushing mill powder machine
Feed bin is typically equipped with the material-level detecting device connecting with milling machine controller, and when detecting that bin-level is excessively high, grinding roller is certainly
It takes offence closure, prevents the generation of blocking phenomenon (putty can also damage grinding roller)；When detecting that bin-level is too low,
Grinding roller automatic pneumatic is opened, in the case of avoiding no material, the occlusion abrasion of grinding roller tooth.
Traditional material-level detecting device generally uses weight method or capacitor plate method to detect material position, the one-way for induction of weighing
It not can reflect putty, the shortcomings that capacitor plate method is that Ultramicro-powder can be attached to its inner wall, to influence detection accuracy.In short,
Existing material-level detecting device is undesirable, cannot achieve the effective protection to grinding roller, it is necessary to be improved.
Utility model content
The purpose of this utility model is that aiming at the disadvantages of the prior art, providing a kind of material position inspection for roller-crushing mill powder machine
Device is surveyed, to realize to the effective protection of grinding roller, extends the service life of grinding roller.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of material-level detecting device for roller-crushing mill powder machine includes bracket, dynamometer and detection arm, the branch in composition
Frame is fixed on the outer wall of flour mill feed bin, and the dynamometer is fixed on frame upper, and the signal output end of dynamometer connects milling
Machine controller, the detection arm lie in a horizontal plane in the top of dynamometer, detect on side wall of the one end of arm by flour mill feed bin
Detection window protrudes into feed bin, and the other end is connect by horizontal rotating shaft with holder pivots, detects the middle part of arm and erecting for dynamometer
Straight measuring rod is hinged.
The above-mentioned material-level detecting device for roller-crushing mill powder machine further includes rubber backgauge film, the rubber backgauge in composition
Film blocks on the detection window on flour mill feed bin side wall, and the middle part of rubber backgauge film is equipped with to be led to what detection arm matched
Hole.
The above-mentioned material-level detecting device for roller-crushing mill powder machine, it is tip-like that the detection arm, which protrudes into one end in feed bin,.
The utility model judges the material position in feed bin according to the stress condition of detection arm, can not only be fallen according to material
When to detection arm apply pressure to determine whether lack material, and can according to when being gushed on material to detection arm apply lifting force
To determine whether putty, in this way milling machine controller can adjust in time the working condition of grinding roller according to testing result, avoid
Putty and scarce material are injured caused by grinding roller, extend the service life of grinding roller.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model.
It is marked in figure as follows: 1, feed bin, 2, rubber backgauge film, 3, bracket, 4, dynamometer, 5, detection arm.
Specific embodiment
Referring to Fig. 1, the utility model mainly includes rubber backgauge film 2, bracket 3, dynamometer 4 and detection arm 5.Wherein, it props up
Frame 3 is metalwork, is welded on the lower section for the detection window on the outer wall of feed bin 1 and being located on feed bin side wall.Dynamometer 4 is fixed on
3 upper middle position of bracket, measuring rod is straight up.It detects arm 5 to be horizontally arranged, the measurement rod end at middle part and dynamometer 4
Portion is hinged, and the one end of one end and bracket 3 far from feed bin 1 for detecting arm 5 is rotatablely connected by horizontal rotating shaft, and the other end is from inspection
The inside that window extend into feed bin 1 is surveyed, the extruding force of all directions material is received.
Material causes adverse effect to dynamometer 4 after detection window spilling in order to prevent, will be examined using rubber backgauge film 2
Window aperture seal is surveyed, detection arm 5 is passed through from the through-hole at 2 middle part of rubber backgauge film, since the thickness of rubber backgauge film 2 is smaller and has
It is flexible, to the active force very little of detection arm 5, it will not influence detection accuracy substantially.
One end that detection arm 5 is extend into inside feed bin 1 is made into tip-like, can reduce the axis that material applies detection arm 5
Xiang Li, the service life of extension detection device.
Working principle of the utility model is:
When equipment operates normally, one downward pressure, the size and material position of pressure are applied to detection arm 5 when material falls
Related, for the pressure through the leverage that is made of detection arm 5 on the measuring rod of dynamometer 4, controller is defeated according to dynamometer 4
Pressure signal out can judge the height of material position.When putty occurs, material can be frequently to turning under the action of grinding roller
It gushes, a upward thrust is applied to detection arm 5, the measuring rod of dynamometer 4 will receive upward pulling force at this time, and controller is accordingly
It can determine whether that putty failure has occurred.When material position is high or putty failure occurs, controller first starts distributing roller and flour mill roller
Mill, delay, which opens clutch and rolls solenoid valve and close, rolls；When material position is lower, controller first controls clutch and rolls solenoid valve from rolling, and delay, which is closed, to divide
Expect roller and roller-crushing mill grinding roller.
The utility model structure is simple, easy for installation, and reliable for operation, suitable for media such as powder, particle, fluids
Material-level measure.
