Portion 214 so that the charging effect of screw feed rod is more preferable；By the way that wear-resisting sheath 215 is arranged at the first warping part so that often Can the first warping part that be contacted with raw material protected, reduce the direct abrasion to the first warping part, improve spiral into Expect the service life of bar；(2) auger bar 302, the lower end position of auger bar are set as by the way that the bar that stirs of raw material will be stirred In in feeding warehouse, auger bar will be sent with the raw material of barrel bottom to top in feeding warehouse, under the action of rotary force from It is thrown away at the top of auger bar, carries out convertible stirring, stirring is more fully and uniform；By by helical mixing blade 304 It is set as the structure become larger from lower to upper so that convertible mixing effect is more preferable；By in the upper end of helical mixing blade It is arranged by the spreading disk 306 of center to edge inclined arcwall face shape gradually downward so that sent to top by helical mixing blade The raw material in portion is arranged at spreading disk, in order to which raw material is preferably spilt so that the mixed effect of raw material is more preferable；(3) By the way that vertical main air hose 401 is arranged on the inner wall of barrel, several be fixed in barrel is set from top to bottom on main air hose Annular averaging wind pipe 402 on wall so that the wind that comes of the generation of centrifugal blower 7 is uniformly directed to each annular after main air hose It in air hose, is finally discharged by the equal air holes 405 on annular averaging wind pipe so that the air circulation in barrel is got up, when raw material is stirring When the dust and moisture that are generated when mixing, it can be carried over barrel with the air of circulation, preferably ensure that the quality of raw material；It is logical It crosses at equal air holes and the equal tuyere 406 of gourd shape is set so that wind can be more smooth in blowout, more there is dynamics, can be effective Prevent shredded plastic piece from blocking air outlet, while the strong wind blown out can also so that the shredded plastic piece in barrel is fitted When stir, also allow for the mixing of not homogeneous raw material, since equal air holes is directed to the center of annular averaging wind pipe, so tuyere exist When in equal air holes, the air outlet of equal tuyere is also the center for being directed toward annular averaging wind pipe so that the wind come out by equal tuyere Directly horizontal blowout, then gradually scattered up and down by horizontal direction so that can all there be air at the gap in barrel between shredded plastic piece The more preferable discharge of dust and moisture is convenient in circulation；(4) by the way that heat riser 5 is arranged on air pipeline 6, centrifugal blower is blown Air in feeding cylinder is heated, and can be carried out heating, drying to the shredded plastic in barrel, be improved the quality of raw material；Pass through Two pieces of opposite support plates 502 are set in shell 501 to fix heating tube 506, the card slot 505 of insulated ring 504 is stuck in fixation At hole 503, be mounted in insulated ring by heating tube, it is simple in structure, it is easy for installation, while insulation performance is preferable, safety compared with It is high；Waterproof layer 509 made of calcium carbonate are set between the plug 508 and shell 507 of heating tube, external moisture can be prevented It penetrates into inside heating tube and causes to leak electricity, safety is higher；By filling crystal magnesium oxide powder between shell and resistance wire 510 511 so that

material of conveying Carry out certain stirring so that raw material begins to mix when conveying at the beginning；Silicon carbide has preferable wear-resisting property, as Wear-resisting sheath 215 rubs with raw material, is protected to helical blade, and the service life of helical blade is extended, and reduces Maintenance cost；The restriction of 213 number of arc groove 209, annular groove 210 and hemisphere jut is ensureing that connection structure is uncomplicated Meanwhile it is easy to connect, connection effect is preferable, and positioning column 218 coordinates with arc groove, is located at after annular groove for hemisphere jut Final locking, easy to operate, locking effect is preferable；(7) by the way that 307 shape of several arc panels is arranged in the disk of spreading disk 306 At several spreading channels 308 so that when spreading disk rotates, raw material can be thrown away from different spreading channels, be spilt evenly, So that the raw material stirring and mixing effect in barrel is more preferable；Quantity limitation to arc panel, can preferably form appropriate number of Spreading channel, convenient for preferably being distributed raw material so that it is more preferable to spill mixed effect；By the spiral of arc panel on spreading disk Direction is set as the rotation direction with agitating shaft on the contrary, also for the rotation direction for adapting to agitating shaft so that raw material is to stirring Mix in the case that axis generates minimum drag, by it is a kind of naturally in a manner of throw away and spill out, it is preferable to spill effect for reasonable design；It is logical It is perpendicular to cross setting stirring rod 217, the contact position of stirring rod and helical mixing blade 304 on helical mixing blade so that spiral shell Stirring blade is revolved while upward helical feed raw material, plays certain stirring, top spills and internal stirring two ways It is carried out at the same time, ensures the good mixing of raw material in barrel；It is vertical bar column to set stirring rod to lower end, and upper end is the circle of opening The structure of arcuation ensures preferable mixing effect with a kind of relatively simple structure, easy to use；(8) by main air hose 401 It is upper that three mounting holes 407 are set again between adjacent annular averaging wind pipe 402, the equal tuyere of gourd shape is equipped at mounting hole 406, sufficient utilization is done to the surface of main air hose so that there are not external wind, barrel in dead angle in barrel Inside have air circulation everywhere, and by between mounting hole installation position and setting angle all done strict regulations, be exactly in order to Ensure that best air-out effect, design are relatively reasonable；While round and smooth excessive throat structure 408 is so that wind energy is enough smoothly blown out Also there is larger power so that the wind of equal tuyere blowout more has intensity；Specific amount of setting so that the cylindrical section of barrel Inner wall at the annular averaging wind pipe 402 of equally spaced setting from top to bottom, ensure airflow effects；The air outlet of all equal tuyeres refers both to To the center of annular averaging wind pipe, being arranged on annular averaging wind pipe for angle is provided with enough equal tuyeres, ensures annular Outlet air is uniform at averaging wind pipe；(9) polyimides has heat resistance, cold resistance, weatherability, electrical property and anti-flammability so that absolutely The electric insulating effect of edge circle is preferable, and service life is longer；The design of 501 structure of shell so that air enters after shell can be into Row buffering and wind speed are adjusted, and good heating of the air in shell, infrared heat lamp 515 has heat source soft, and safety is higher The characteristics of, the infrared heat lamp of lower part can in advance be preheated to entering the air at heating tube, the infrared heat lamp on top Also supplement appropriate can be carried out to the heating effect of heating tube；So that the reasonable quantity of heating tube 506, ensures air in shell Heating effect.
