Description
The present invention relates to the rolling distance regulator of kibbler roll, in a casing of this equipment two mixing rolls are arranged, one of them is can rotating roller; Also have guiding mechanism and one to adjust the device of roll clearance automatically by the remote control drive motor in addition, the latter is coupled through connecting in the middle of the clutch by transition utensil and guiding mechanism.
Roll clearance for kibbler roll is adjusted equipment, must consider three kinds of special modes of operation specially:
If any bigger foreign matter, for example screw enters in the roll clearance, and the compression shock power that is occurred must lower (bearing) immediately, and this realizes insuring with mechanical overload by cracker usually.
The second, do not having under the situation of abrasive material, mixing roll (especially when it is anilox roll) must enter the position of mutual disengaging automatically, otherwise two mixing rolls will grind mutually owing to their different revolutions, are damaged.
At last, for normal grinding operation, must adjust the roll clearance of mixing roll accurately.
Experience up to now shows, adjustment for roll clearance, machinery rolling distance regulator than other, for example corresponding hydraulic adjustment device is superior, for the roll clearance adjustment of kibbler roll, although itself be simple with regard to its adjustment process, but, as finding out from European patent item 13023, just generally speaking, this is a quite complicated process.For example, up to the present also can not ask and calculate definite parameter (for example grinding pressure or motor power consumption) with satisfactory way, and these parameters are for automatic adjustment mixing roll, just adjust roll clearance (roller spacing), according to corresponding requirement, can be used as suitable initial parameter.Consider from economic angle, also need to limit in quantity adjust necessary and can collect influence parameter.Each is adjusted automatically, needn't directly detailedly from the outside look, and just carries out control and adjustment process; Under normal circumstances, without manual operation.If will make lapping device energy optimum operation, all unpredictalbe disturbing factors (can cause because of various reason) are a pith of people's operating equipment all the time.If both required automatic adjustment, require manual operation again, just have to purchase very expensive complete equipment.
In view of the above, task of the present invention is when the oppositely rolling roller crusher seat keeps the manual operation possibility, for the automation that roll clearance is adjusted, to seek a kind of particularly advantageous solution.
According to the present invention, the device that beginning is named for this paper, this point realizes by following several respects: guiding mechanism constitutes self first an enclosed combiner, this combiner has the adjustment component (latter has long and short lever arm) of lever speed change, is placed in the side in the mixing roll scope; Drive motor and clutch constitute second kind of combiner, and it is settled with the spacing of first kind of combiner, and at this moment, the adjusting masterpiece of being drawn by drive motor is used on the long lever arm of adjustment component; The additional manual adjusting device that is equipped with of guiding mechanism.
Up to now, for the solution of the kibbler roll of operable automatically, be starting point all the time with following, promptly be exactly to consider from the structure angle, also be to pay the utmost attention to automatics rather than manual handling equipment; And solution in the past, major part is to make correspondingly direct be connected with the pulling force chain link of adjusting mixing roll (examination is the Fig. 6 of European patent Nr.13023 relatively) of a back geared motor.On the contrary, solution of the present invention be make traditional adjustment means comprehensive become one self, enclosed parts, this point shows soon, meets the requirements especially according to the conduct proof that the present invention passed by, and surprisingly has many advantages in practice.Solution of the present invention shows, replaces the manual adjustment mechanism that uses so far with automatics, is not to cause a kind of new grinding mode, roller " softened " or " sclerosis " or the like.Main is the stability that keeps mixing roll to adjust by the present invention.
Thereby device according to the present invention is replenishing of oppositely rolling roller crusher, can settle kibbler roll at any time thereafter, and but, the part of a grinding machine kibbler roll should be equipped with automatics.Because kibbler roll for mode of operation (processing of granular material), has been a kind of very compact machinery so far, the second cover parts of settling according to the present invention in the right roll clearance of mixing roll, do not increase the difficulty that adopts other elements.If desired, the roll crushing support then even also can be without automatics, but operates by the manual adjusting device of guiding mechanism.
The present invention is a kind of structural form with multiple advantage, and its clutch constitutes a kind of adjustable slip-clutch, and this may be in the mode of excellence according to rated value given in advance, and for example the spacing of mixing roll makes roller regulation mechanism of grinding realize automation.Here, adjustment can be that the rated value system diagram is realized according to program given in advance.Owing to disturb in practice is inevitably, so slip-clutch is answered the limit erroneous operation.So also can prevent: grind slit or the pressure too high value of furnishing unconsciously; Kibbler roll or roller bearing are destroyed.
Below this situation prove existing advantage, operation is convenient again: respectively there is first kind of combiner the both sides of mixing roll bearing end, next is that the both sides of bearing end have second kind of common combiner, also have auto-paralleling to adjust the means of roller in addition, first kind of combiner can be controlled by second kind of combiner through a non-slip transition transmission.Like this, ancillary equipment on the kibbler roll of having put into operation already especially easily, and this point can allow the bigger economic worth that keeps it to embody to all existing roll crushing supports, and can replenish the equipment kibbler roll with other automation equipments, and not need to set up new kibbler roll.
The present invention in view of another easy to operate make with advantage is, drive motor is by transition transmission utensil, chain transmission regulating shaft for example, and the latter acts on the long lever arm of adjustment component, and short three times of the length of long lever arm ratio are outstanding good.Be equipped with a manual adjustment wheel on the regulating shaft, the general indicating equipment that is equipped with a dial gauge form of this regulating wheel.Indicating equipment of the general outfit of manual adjustment wheel is the position indicator, and this indicator generally constitutes the shape of dial gauge, and dial gauge shows that as survey table structurally can directly concentrate in the handwheel.Like this, handwheel is all correspondingly accepted each automatic correction value simultaneously, and correspondingly shows on handwheel.If second kind of combiner is positioned on foot's scope of kibbler roll, just have more superiority.
The make that rolling distance regulator another kind of the present invention has advantage is that a position signal device is arranged, and the latter is controlled by transition transmission utensil or guiding mechanism.Preferably pacify such position signal device, for example a potentiometer.The mode that has advantage especially is, transition transmission utensil is by non-slip transition transmission transmission adjusting power, and at this moment, the electric potential signal device directly is coupled by a chain or with non-slip transition transmission or with the driving side of clutch.Non-slip transition passes device and preferably adopts tooth belt, or chain or similar devices, so that can drive position signal device simultaneously.
The general position signal device that is connected with a suitable position indicator, can show and feed back the exact position of two mixing rolls at any time, especially when position indicator is placed in the transmission side of clutch, when just directly forcibly being connected, all the more so with guiding mechanism.Practical operation proves, peace one digital display and manual input button on the casing of kibbler roll, and the operating personnel by position signal device control drive motor, and are then more suitable.These can be by the operating personnel that are responsible for, and for example grinding machine is long suitably controls drive motor, if correspondingly obtain desirable roller position value.
The structural form that roll clearance of the present invention, adjusting device have advantage equally is that peace one digital display and manual input button on the casing of kibbler roll are in order to the control drive motor; A programme controlled computer preferably is installed in addition again, and the remote control drive motor is preferably pacified a common central computer of connecting with the computer of a plurality of kibbler rolls again to this program-con-trolled computer.But, in some cases, do not realize series connection here, and only settle a common computer (possess one or more rated value memories, store the value of a plurality of kibbler rolls), also have an enormous advantage.By above-mentioned measure, can be according to rated value system diagram given in advance, promptly an accurate control procedure is directly controlled all kibbler rolls.
At this moment, except that control procedure, rolling distance regulator also can be the part of a precise adjusting device, at this moment, grinds the result, and promptly the grain fineness that draws according to the roll clearance width is elected to be factor to be transferred, and controls according to roll clearance.
Input at the aforementioned calculation machine; generally can install attached mixing roll the grinding pressure tester and (or) the output signal device of voltage limiting value switch; at this moment; can optionally use the voltage limiting value switch and (or) spacing value switch so that the disturbed condition that causes of control instruction that sends mistake owing to the roll clearance adjustment is carried out overload protection.Generally be input end and computer settle attached mixing roll the power consumption tester and (or) the output signal device of power dissipation limits value switch.But, equally generally also can input end and computer settle attached roller spacing tester and (or) the output signal device of spacing limiting value switch.
If the selectable limiting value to grinding pressure or power consumption or roller spacing is equipped with an adjustable safety element,, then also has its advantage so that can work to motor and manually operated adjusting device simultaneously.
According to schematic diagram the present invention is further described in principle below:
The rolling distance regulator of the kibbler roll of Fig. 1 band motor of the present invention governor motion;
Fig. 2 is according to the kibbler roll of Fig. 1, front-view schematic diagram, and the existing motor adjustment in the both sides of this machine also has manual adjustment mechanism;
Fig. 3 this be and different another kind of version shown in Figure 2, and all there is manual adjustment mechanism its both sides, but has only a motor transmission mechanism, so that parallel adjustment mixing roll;
The motor governor motion of Fig. 4 illustrative rolling distance regulator of the present invention and its computer.
Fig. 1 is a kibbler roll, and it has, and guiding mechanism is made first kind of combiner 1 and controllable adjusting transmission mechanism is made second kind of combiner 2.Two mixing rolls 41 and 42 are by 3 supportings of a common support.Roller 42 is fixed on the fixing cam pin 4, and it can turn round, and at this moment, starting and disconnected connection are by lever 5 and separate oil cylinder 6 and control.By the gyration of lever 5, make cam pin 4 rotation, but and cause the horizontal displacement of floating bearing case 7 lower parts, thereby reach the purpose of the spacing coarse adjustment of two mixing rolls.Yet for accurate adjustment, this equipment is very coarse.Thereby, have only when making two mixing rolls 41 and 42 enter starting or disconnected connection position, just use this equipment when just entering two fixed positions.Real fine setting realizes that by regulating shaft 8 it adjusts arm 9 around fixing gantry post 10 motions by rotating directly to make.Adjust lever arms short above the arm 9 by connecting rod 11 with can be connected with a joggle by rotating bearing housing 7 power.The energy transmission realizes that by cutter cutter is the part of overload spring insurance on a side.On corresponding opposite side, the pressure test equipment of an adjustable bracket knob 13 and band pressure-indication means 15 is arranged on the connecting rod 11.For can adjust mixing roll abreast when operating, the correction work on a required side can be finished by adjusting screw 43 and 44.Regulating shaft 8 is by bearing 10 ' fixedly hold on, and it can only be by directly being equipped with dial gauge 17(Fig. 2) handwheel, or by the motor means, promptly operate by transition chain 18 and back geared motor or drive motor.Drive motor 19 is fixed on the roll crushing support 26, be in slip-clutch 20 and sprocket wheel 21 above, sprocket wheel 21 directly is connected with regulating shaft 8 with transition chain 18.
In addition, position signal device 22 directly is connected with transition chain 18 with sprocket wheel 24 by chain 23, and like this, each motion of transition chain 19 all is recorded in the position signal device 23, and is continued to be transmitted to desirable position.By Fig. 1 and 2 as can be seen, for the motor regulating measure, only need few discrete component.Maximum element, drive motor 19 and clutch 20 generally can be placed in the scope in roll crushing frame 26 following spaces, like this, just can on the existing roll crushing support of relative configurations, replenish at any time and settle second kind of parts, the i.e. automatic mechanism of roll clearance.Like this, parts also can be made into the form of closed combiner when suitable structure, thereby can be easy to and accelerate replenish installment work.Because the roll crushing support generally all is the double structure formula, so, with center line 27 signals of imaginary point in Fig. 1.Each roller of two half kibbler roll seats is right, can equip or not equip this automatic governor motion.
Version shown in Figure 2, each bearing side all is equipped with parts 1 and 2.At this moment, having a kind of may be respectively to pacify a handwheel 16 with integrated dial gauge 17 in both sides.Two bearing sides correspondingly have 19, one position signal devices 22 of a drive motor and a transition chain 18.Like this, on two bearing sides, the roller spacing can be controlled by motor 19 and chain 18, or is adjusted by handwheel 16 by operating personnel.But, also can be without dial gauge 17, and adopt digital display 45 and manual input button 46.Also it is contemplated that there is the stage of a custom, can be equipped with handwheel 16 simultaneously and manually import button 45 for making operating personnel.Also can settle digital display 45 or dial gauge 17 separately, the two perhaps is installed simultaneously, this has its advantage in some cases.
Fig. 3 is the selection scheme of Fig. 2 structure.At this moment, in order to carry out single correction, on the left side and the right only dispose handwheel 16 and dial gauge 17, promptly compound configuration.Also have a kind of more simple proposal, just whether about dispose handwheel, but only settle handwheel 16.A side the correction that must carry out, can finish (Fig. 1) by nut 43 and 44, thereby, only need the handwheel 16 of a band dial gauge 17, this is applicable to bigger grinding machine, and seldom changes product and mix situation, promptly is identical final products all the time.The adjustment of roll clearance also can be finished by drive motor 19 among Fig. 3, and at this moment, adjustment stroke is delivered to another bearing side by chain 39 and 40.Adopt this mode to regulate mixing roll abreast by corresponding automatics.
Fig. 1 illustrates mixing roll 41 and 42(only with dashed lines) transmission mechanism 28.Also can in transmission system, dispose an electric power consumption test and an indicator 29.Like this, can make electric power-consumption limitations in lower limit and higher limit; When it surpassed the scope of institute's preliminary election, mixing roll just was separated from each other out.
Another kind may be to determine effective spacing (comparison diagram 1) of bearing housing parts by test of roller spacing and indicator 30.Particularly when using anilox roll, can prevent wrong instruction reliably by roller spacing supervising device in simple mode, it is a part of mechanical failure of kibbler roll at least that this instruction will cause.
Fig. 4 illustrates this other control connection additional equipments once more.According to Fig. 4, all signals of roll crushing support are all coordinated by computer 31 and are controlled, and at this moment, this computer can call necessary rated value from the central computer 32 that has memory 33.According to Fig. 4, position indicator 22 also is equipped with a position limit value switch 34, and it can adjust desirable limiting value, so that stop wrong the adjustment by automatics.The advantage of position limit value switch 34 positions shown in the figure is that it also can stop mistakenly manually adjusts, because handwheel and automatic governor motion can make transition chain 18 and chain 23 corresponding travel displacement occur.Position signal device 22 also has governor motor 19 equally, can be connected with an input-output instrument 35, and the latter receives corresponding signal from computer 31, and it is sent, and this is equivalent to the digital display 45 among Fig. 2 and manually imports button 46.Equally, pressure test can be connected with computer 31 with 15 with display unit 14.According to the dismounting degree of a bench roller formula disintegrating machine, can assemble one or several insurance in the above.Go into anilox roll as peace, the then effect of grinding pressure watch-dog and little, on the contrary, the spacing by position indicator 22 or rangefinder 36 monitoring mixing rolls is then highly significant.The situation of smooth roller is just in time opposite, and it is a lot of that it is carried out the pressure monitor benefit.Computer 37 and signal line 38 among Fig. 4 should illustrate, the computer 32 that has a memory 33 is being controlled the great majority in the grinding machine, in some cases or even all roll crushing supports, if desired, goes back tunable and adjust function.
If digital display 45 sends show value with the same way as of handwheel display demonstration numerical value, as if the value (for example handwheel is in 15.30 o'clock position, just digital display illustrates 15: 30) that clock and watch show just has its special superiority.
Its huge superiority also shows the empirical value of roll crushing support more non-automaticization or non-remote control, and the formation or the improvement of corresponding control program are estimated.
