As shown in Figures 2 and 3, the control setup that belt provided by the utility model is quantitatively carried comprises discharging shake groove 1, tiltedly feed belt 2, impregnating autoclave 3, electronic scale 4, controller 5 and frequency converter 7, wherein: the shake outlet of groove 1 of discharging is arranged on the feed end top of oblique feed belt 2, and the discharging outlet of groove 1 of shaking be oppositely arranged with the oblique feed end of feed belt 2.The import of impregnating autoclave 3 is arranged on the below of oblique feed belt 2 discharge ends, and the import of impregnating autoclave 3 is oppositely arranged with oblique feed belt 2 discharge ends.Pipe tobacco, via the discharging groove 1 that shakes, drops to oblique feed belt 2, by oblique feed belt 2, is transported to impregnating autoclave 3.
Discharging groove 1 top that shakes arranges electronic scale 4, and electronic scale 4 can adopt HAUNI electronic belt scale of the prior art, but is not limited to this.The shake import of groove 1 of discharging is relative with the discharge port of electronic scale 4, and pipe tobacco is by after electronic scale 4 like this, just enters into the discharging groove 1 that shakes, and electronic scale 4 collections are fallen the instantaneous flow of tobacco of oblique feed belt 2 by the discharging groove 1 that shakes, and export to afterwards controller 5.Electronic scale 4 is connected with controller 5, and controller 5 receives described instantaneous flow of tobacco, and exports the control signal of oblique feed belt 2 running frequencies.Frequency converter 7 is connected with controller 5, receives the control signal of oblique feed belt 2 running frequencies, and produces corresponding frequency output.The mouth of frequency converter 7 is connected with the power intake of oblique feed belt 2, controls the running frequency of oblique feed belt 2.What controller 5 adopted is programmable logic controller (PLC).Variable frequency control mode can be so that tiltedly the frequency control of feed belt 2 be more flexible.
The utility model arranges electronic scale above shaking groove in discharging, and the discharging import of groove of shaking is relative with the discharge port of electronic scale, pipe tobacco is by after electronic scale like this, just enter into the discharging groove that shakes, pipe tobacco is again via the discharging groove that shakes, drop to oblique feed belt, by oblique feed belt, be transported to impregnating autoclave, electronic scale can weigh the instantaneous flow of tobacco of the pipe tobacco by it, then by by this instantaneous flow of tobacco input control device, obtain the running frequency of an oblique feed belt, flow to frequency converter, and then make oblique feed belt according to the frequency operation of frequency converter output, therefore at oblique feed belt along pipe tobacco throughput direction width all under identical precondition everywhere, the height that tiltedly on feed belt, pipe tobacco is stacked will keep even, thereby guaranteed the stable of every batch of pipe tobacco weight that enters impregnating autoclave.
Pass between the running frequency of instantaneous flow of tobacco and tiltedly feed belt is: h=m/k; Wherein: m is instantaneous flow of tobacco.H is the running frequency of oblique feed belt, and because needs guarantee permission length and the cloth height of pipe tobacco on oblique feed belt as far as possible, therefore tiltedly the running frequency of feed belt is controlled between 15hz-30hz conventionally.
K serve as reasons length and the definite preset value of pipe tobacco height of oblique feed belt, its reason is mainly:
1, for the length of oblique feed belt, this length scale is fixed, according to technological requirement and technical requirements, the pipe tobacco of preset weight needs uniform spreading to be located on oblique feed belt, and leaves surplus along the front end of pipe tobacco throughput direction pipe tobacco with the discharge end of oblique feed belt.The concept of casehistory " surplus ": such as the weight of pipe tobacco is M, tiltedly the length of feed belt is L, now pipe tobacco need to spread the 2/3*L of oblique feed belt overall length, now along the front end of pipe tobacco throughput direction pipe tobacco and the surplus 1/3*L of the discharge end of oblique feed belt.
2, for pipe tobacco height, because there is the cover of certain altitude in the position of oblique feed belt discharge end, therefore pipe tobacco height can not surpass the bottom of this cover to the distance of oblique feed belt, to prevent that pipe tobacco height from surpassing the putty phenomenon that this pipe tobacco height is caused.
Because instantaneous flow of tobacco is all thousands of order of magnitude, and tiltedly the numerical value of the frequency converter of feed belt is only 0-50, so K value is arranged to be greater than 1.
This shows, instantaneous flow of tobacco and tiltedly the running frequency relation in direct ratio of feed belt, the instantaneous flow of tobacco that HAUNI electronic belt scale weighs is larger, tiltedly feed belt running velocity is just faster, thereby at oblique feed belt width is identical everywhere in the situation that, tiltedly on feed belt, pipe tobacco is stacked height and is just directly proportional to the speed of its operation, to guarantee stablizing of pipe tobacco amount on oblique feed belt.
When instantaneous flow of tobacco is less than default flow of tobacco, tiltedly feed belt adopts crawl operation.Default flow of tobacco is not less than 1000kg/h conventionally, the factor that the size of this default flow of tobacco need to be considered is conventionally: the frequency converter that prevents oblique feed belt moves under ulf, this is because be less than default flow of tobacco once instantaneous flow of tobacco, the instantaneous load of HAUNI electronic belt scale is very little, now need to utilize experience time and empirical Frequency to adjust the frequency of frequency converter and the time gap of operation, the flow of tobacco stability while realizing low discharge.The second factor that the size of default flow of tobacco need to be considered is: guarantee to be no more than the peak work capacity of himself by the flow of tobacco of HAUNI electronic belt scale, thereby play the effect of protection electronic scales.
When instantaneous flow of tobacco is more than or equal to default flow of tobacco, pass between the running frequency of instantaneous flow of tobacco and tiltedly feed belt is: h=m/k, wherein: the running frequency that h is oblique feed belt, m is instantaneous flow of tobacco, k the serve as reasons length of oblique feed belt and the oblique definite amount of outer cover height at feed belt discharging opening place, k is greater than 1.Being arranged on above of h and k all elaborates, and do not repeat them here.
When the control setup that uses belt provided by the utility model quantitatively to carry carries out work, when the accumulating weight of pipe tobacco reaches default total weight, the discharging groove 1 that shakes stops charging.Such as: the maximum weight of each batch of permission of technological requirement cloth on oblique feed belt 2 is 320kg, when the accumulating weight of HAUNI electronic belt scale reaches 320kg, the accumulating weight that is pipe tobacco reaches when presetting total weight, HAUNI electronic belt scale stops to the discharging groove feeding tobacco-thread that shakes, further to guarantee the stable of every batch of pipe tobacco weight that enters impregnating autoclave, make it to meet setting value.
In discharging, shake when groove 1 stops charging, tiltedly feed belt 2 continues the running frequency motion of shaking before groove 1 charging according to stopping discharging, until pipe tobacco is transported to the discharge end stop motion of oblique feed belt 2.That is to say, when the accumulating weight of pipe tobacco reaches in the situation of default total weight, HAUNI electronic belt scale stops to the discharging groove feeding tobacco-thread that shakes, but in order to guarantee the cloth evenness of pipe tobacco on oblique feed belt simultaneously, need to proceed cloth to being deposited in the shake pipe tobacco of groove of discharging.
Judge that the method whether pipe tobacco is transported to the discharge end of oblique feed belt is: along the pipe tobacco throughput direction distance position that tiltedly discharge end of feed belt is preset length, a height sensor is being set, once height sensor detects pipe tobacco altitude signal, controls the out of service of oblique feed belt.
In order to guarantee discharging, shake groove after stopping charging, the pipe tobacco being deposited in wherein is all routed on oblique feed belt, and therefore, discharging is shaken after groove 1 stops charging, discharging groove 1 delay working that shakes, the tobacco material until discharging is shaken in groove 1 falls to oblique feed belt completely.Conventionally after time delay 3-5s, then stop the discharging discharging work of groove 1 of shaking, thereby can guarantee that the material that deserves to be called the 320kg having passed by HAUNI electronic belt can drop on oblique feed belt 2 completely.
In above-described embodiment, the control setup that belt provided by the utility model is quantitatively carried also comprises height sensor 6, wherein: height sensor 6 is arranged on along the pipe tobacco throughput direction distance position that tiltedly discharge end of feed belt 2 is preset length.Height sensor 6 is connected with controller 5, and height sensor 6 detects the altitude signal of pipe tobacco on oblique feed belt, flows to controller 5, and controller 5 is controlled the start and stop of frequency converter 7 according to pipe tobacco altitude signal, thereby controls the start and stop of oblique feed belt 2.Set forth above, the pipe tobacco of preset weight needs uniform spreading to be located on oblique feed belt 2, and leaves surplus along the front end of pipe tobacco throughput direction pipe tobacco with the discharge end of oblique feed belt 2.Still the weight of pipe tobacco of take is M, and tiltedly the length of feed belt is L, and pipe tobacco need to spread the 2/3*L of oblique feed belt overall length, along the front end of pipe tobacco throughput direction pipe tobacco, is now that example describes with the oblique surplus 1/3*L of the discharge end of feed belt.In this embodiment, height sensor 6 need to be arranged on the distance position that tiltedly surplus of the discharge end of feed belt 2 is 1/3*L, therefore, once pipe tobacco front end runs to height sensor 6 positions, controller 5 sends work order to frequency converter 7, controls the out of service of oblique feed belt 2.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
