Bevel gear set includes being located on two screw rods the helical gear each other with engagement, the rotation direction of beveled gear teeth and place screw rod Rotation direction is consistent.Present design is that bevel gear set is not limited to one group in order to improve the shear extrusion effect to sizing material further, when When being provided with many group helical gears, it is provided with helicitic texture between group and group, sizing material is played conveying effect, it is to avoid blocking.
Rotor set at least includes the one in shearing-type and meshing rotor structure；Rotor set includes shearing-type and meshing rotor knot During structure, the shearing rotor structure feeding section being located closer to plasticized screw on plasticized screw；In present design, rotor Group has preferable shear-mixed effect to sizing material, and shearing rotor structure is mainly used in sizing material and tentatively mixes, it is preferred that will Shearing rotor structure is disposed proximate to de-connect at structure feeding mouth.
The feeding section of plasticized screw is gaining twist；In present design, the design of gaining twist is for ease of material feeding, increases Compression ratio, accelerates the fltting speed of sizing material, and flight pitch diminishes along with the conveying flight pitch of material.
Feeding pressure mechanism includes circular cone screw rod conveyor and is arranged on the hopper de-connecting Plasticator feeding mouth；In present design, circular cone The basic circle size of screw rod is constant, along with material conveying pitch and spiral groove depth constantly diminish, forms conical screw, this structure Screw rod improve conveying capacity to rubber powder.
Profiled section includes head and roller, it is achieved the extrusion molding slice of reclaimed rubber.
The present invention also provides for a kind of process using described equipment to prepare reclaimed rubber, and the method includes,
Waste Crumb rubber and activator, reclaiming aid etc. being stirring evenly and then adding into feeding pressure mechanism, opens and de-connect Plasticator, sizing material exists Under the effect of self gravitation and feeding pressure mechanism pushed to de-connecting mechanism；
The plasticized screw de-connecting mechanism rotates material feeding, and plasticized screw rotating speed is 30～60 revs/min, the temperature of plasticized screw feeding section Controlling at 50～80 DEG C, the temperature of the section of de-connecting controls at 120～150 DEG C, and the temperature of extruding zone controls at 60～90 DEG C.
Sizing material is extruded to shaping mechanism and carries out tabletting after de-connecting, put in storage after parking.
