Working process of the present invention and principle:
During work; Rubber powder gets into feed end pipe 12, under automatic controlling system from rubber powder feeding bin 11; Variable-frequency motor 18 drives the spring loaded spiral conveying mechanism high speed rotating of hollow with the rotating speed of 1000-1500r/min; Generation frequent shake, rubber powder is upwards carried, and has especially used carrier pipe 3 that tetrafluoroethylene etc. has high lubricity and a wear-resisting material through the whisker that rotates up and down and the frictional impact and the cutting of carrier pipe; Make the caking rubber powder in the process that rises to storage bin more than 5 meters, tentatively smashed granularity below 6 millimeters.Lay a good foundation for realizing meticulous metering.Rubber powder is got in the band level gage storage bin 2 by discharge port 19.
Rubber powder gets into storage bin 23 from opening for feed 27; In robotization control continuous dosing operational process; When storage bin 23 charge levels reach upper limit material level 26; Limes superiors position level gage 2-1 promptly sends the material level detection signal to automatic control system, is sent to pay-off by automatic control system to stop the feeding wave, and feeding stops; Rubber powder is from discharging 4 dischargings; When charge level reached bottom limit state 25, smallest limit position level gage 2-2 promptly sent the material level detection signal to automatic control system, was sent to rubber powder transfer roller 1 by automatic control system to start the feeding wave; Material loading motor 18 operation starts continue feeding; Go round and begin again, remaining has an amount of material in the rubber powder storage bin, and guarantees continuously reliable feed, has reduced operator's labour intensity simultaneously.Rubber powder is from the discharge port 24 of storage bin 23, through last uncovered 341 (being opening for feed) the entering distributor of distributor 3.
During distributor 3 work, the starting position of metering roll 36 is positioned at both sides up and down for metering box 362, at this moment; Rubber powder falls in the metering box 362 of metering roll 36, during work, is controlled by stepper-motor 31; Metering roll 36 is realized spinning upside down feeding intake through rotating; Revolution half-turn bottom metering box 362 feeds intake once, and 362 chargings of top metering box once go round and begin again.According to processing requirement, corresponding different charging capacitys, the not isometric metering box 362 of dress can crouch in scale tank 361; And through adjusting the rotating speed of stepper-motor 31; The injected volume of accurate measurement rubber powder is thrown in precision and can be reached 10 grams, the especially even setting of scale tank on the metering roll 36; Make the rubber powder uniform distribution, evenly feed intake.In automation control system, can make production technique be able to effective execution by manufacturing technique requirent at any time through the rotating speed adjustment rubber powder injected volume of adjustment stepper-motor, avoided personal errors, guaranteed the permanent stability of quality product.Rubber powder through metering is that discharge port 342 gets into last uncovered 461 (being opening for feed) of beating crusher 4 from the distributor lower open mouth.
Rubber powder is smashed processing before rendering to reaction kettle 5 productions; By automatic controlling system, be under running up of 1200-1600r/min drives at flour motor 41 rotating speeds equally, the connected steel-tooth flour rod 45 steel-tooth brute forces through inclined in opposite directions impact rubber powder; Fully it is smashed the fine powder state that is reduced into; And be dispensed onto equably in the reaction kettle 5, in reaction kettle 5,, avoid rubber powder by the hard pitch wrapping agglomeration through comprehensive powerful stir rapidly and matrix pitch fully merges; Thereby shortened process has improved production efficiency.
The above only is the preferred embodiments of the present invention, is not shape material of the present invention and structure are done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
