Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The working principle and its related details of the utility model are further described with reference to the accompanying drawing.This kind of twin-screw extrusion The collection device of machine, including organic frame, be disposed in the rack water-cooling section 30, air cooling section 32, granulating mechanism 25, Screening part 33 and transfer unit, the water-cooling section 30 include sink 31, and pressing plate 21, sink are provided in the sink On be provided with bridge crossing plate 22, continuous threaded plastic 20 after molding enters sink, bypasses from the lower section of pressing plate 21, and by passing a bridge The top of plate 22 bypasses, and pressing plate 21 then guarantees that plastics enter in sink 31, and plastics is avoided to expose the surface, and the setting of bridge crossing plate 22 makes Plastics expose in air, into air-cooled processing；The air cooling section includes baffle 23, blower and gas nozzle 24, the gas nozzle 24 connect with blower, and the baffle 23 and gas nozzle 24 are respectively mounted on the rack, and the baffle 23 and gas nozzle 24 shift to install, modeling Material is bypassed from the top of baffle, and the top of plastics is then arranged in gas nozzle, and the gas nozzle is flat, more plastics in this way 20 can be blown to by cold wind, according to cooling requirement, multiple groups gas nozzle 24 can be set and radiate；The granulating mechanism 25 includes Traction element, pelletizing component and discharging platform 27, the traction element include traction roller, and plastics are by traction roller by defeated forward It send, the pelletizing component includes hobboing cutter, and the lower section of hobboing cutter is arranged in the discharging platform 27, and is covered with above the hobboing cutter Plastic grain is prevented to be detached from the flexible backgauge part 26 of discharging platform, the backgauge part 26 extends in discharging platform 27, the flexible gear Materials and parts are cloth, and cloth is soft and quality is light, can be gathered the plastic grain of cutting in discharging platform 27, and will not influence The conveying of plastic grain；The screening part 33 includes sieve 28, material receiving desk 35 and vibrator 34, and the setting of sieve 28 exists The lower section of material receiving desk is arranged in top on material receiving desk 35, the vibrator 34, and the rear end of the sieve 28 and discharging platform 27 connect It connects, the front end of the sieve 28 is connect with waste channel, and the discharging platform 27 is obliquely installed most preferably, i.e. the front end of discharging platform 27 is low In rear end, guarantee that the plastic grain after cutting can smoothly enter into sieve 28 in this way；The transfer unit includes vibrating disk 36 and receives Charging basket 37, the material receiving desk 35 are connected with the feed inlet of vibrating disk 36, and the discharge port of the vibrating disk 36 is connected with rewinding bucket 37, The helical orbit 29 of the vibrating disk is provided with multilayer, and helical orbit 29 is longer, and the stroke of plastic grain conveying is longer, conveying Time is also more long, in this way cut off after plastic grain can be radiated on spiral tracks with further progress, so guarantee into In the complete state of cooling when entering rewinding bucket.

After material is squeezed out by extrusion die, molding threaded plastic 20 is fed forward by traction roller, and plastics 20 are introduced into Sink 31 be quickly cooled down, plastics 20 pass through water cooling, then enter it is air-cooled, gas nozzle 24 blows to cold wind with water stain plastics, makes Plastics 20 are further cooling, and keep plastics dry, are provided with two groups of gas nozzles 24 referring to attached drawing, in the present embodiment and radiate, Not only good cooling results, but also guarantee that plastics are dry, cooling and after drying plastics enter cutting mechanism 25, by hobboing cutter by plastics Graininess is cut into, and is dropped down onto discharging platform 27, sieve 28 is entered by discharging platform, since vibrator shakes, if plastic grain ratio The mesh of sieve 28 is big, since this kind of plastic grain is excessive, needs to re-work, and last this kind of plastics into waste material then by leading to Road is uniformly collected, if plastic grain is smaller than the mesh of sieve, plastic grain enters on the material receiving desk 35 below sieve, after And the feed inlet through vibrating disk enters helical orbit 29, vibrating disk 36 makes plastic grain spiral along helical orbit 29 to move up, mould Material particle radiates again in moving process, until completely cooling, last plastic grain is discharged into rewinding bucket 37 by discharge port Interior collection.
