Description

A kind of dual-screw pelletizer

Technical field

The utility model relates to pelletizer technical field, specially a kind of dual-screw pelletizer.

Background technique

Screw pelletizer is a kind of forming machine that can be manufactured material into specific shape, and underwater pelletizer and air-flow are granulated Machine and water spray pelletizer are similar, and environment division is mainly covered, plastic granulator, single double-screw plastic extrusion machine, plastic film blowing machine, Bag Making Machine, printing machine, coating machine, sealing-tape machine, adhesive tape cutting machine, cutting machine, strap machine, modified formula aspect is with alloy material Based on, the material especially to be gone from strength to strength with PET, PC, ABS, these current application regions, plastic formula develops fresh-keeping The formulas such as film, degradative membrane, PET thickening toughening, the difference is that it has one stable water flow to flow through die face, and directly connect with die face The size of touching, pelletizing room crosses die face without limiting water flow temperature, molten polymer to be just enough to make grain-cutter to be freely rotatable From die extrusion, rotating knife cuts pellet, and pellet takes pelletizing room out of by the water Jing Guo temperature adjustment and enters centrifugal dryer, in drying In device, water is flow back to basin, cooling and Recycling, and pellet removes moisture content by centrifugal dryer, and billot production line cost is not Height, it is easy to operate, and cleaning is convenient, this has its advantage for colorant compounding, because the replacement of two batches difference colorant must be thorough Bottom cleaning equipment, still, the shortcomings that making method is that cooling section needs occupied space, and length is come true by the temperature requirement of polymer Fixed, most polymers are before being made final products, it is necessary to which cooperation is kneaded, and is then granulated, is become vendible raw material, is granulated Power needed for machine and extrusion output are proportional, and with strainer size exponent function relation, there are many different nodulizers to design, but All nodulizers can be divided into two major classes, cold palletizing system and die-face hot pelletizing system, and the main distinction of the two is pelletizing The arrangement of journey time, cold palletizing system, in process finally from cured polymer pellets, and in die-face hot pelletizing system In system, pelletizing is carried out when molten condition polymer occurs from mouth mold, and pellet is cooled down in downstream, two kinds of pelletizing systems System respectively has its advantage and disadvantage, cold palletizing system: cold palletizing system includes mouth mold, cooling zone and pelletizing room, and cold palletizing system has two big Class, i.e. sheet stock pelletizer and strand pelletizer, the polymer of melting are cut from hot die extrusion by the rotating knife that ground die face rotates At pellet, the characteristic of this sweet grain system is the water spray pelletizing room of its special designing, and helically line is around because of flowing for water, until outflow Sweet grain room, after pellet is cut, that is, is thrown into water flow, carries out preliminary quenching, and pellet water slurry is discharged into pellet stock tank and is further cooled, It is then fed into centrifugal dryer removing moisture, the usage history of strand pelletizer is almost same as tablet pelletizer long, including Mouth mold, cooling section and grain-cutter squeeze out the mouth mold that the polymer of melting is horizontally mounted by one with extruder or gear pump Billot is formed, billot uses air blower or air after shape of the mouth as one speaks discharge, vacuum facility cooled down, or with water-bath cooling, if Using water cooling, billot need to be blown down moisture with forced ventilation, then be sent billot to pelletizing room, utilize one by a dryer section To the shear action of fixing cutter and rotating knife, billot is accurately cut to required length, but existing dual-screw pelletizer is in life Heat can be generated to raw material when production, such heat can damage product if heat dissipation gently not in time, may when serious Lead to products with adhesive together, people is needed to go to separate again in this way, and isolated product also has different degrees of damage, also increases The labor intensity for having added people reduces the efficiency of production, for this purpose, it is proposed that a kind of dual-screw pelletizer.
