Fig. 2 is the partial schematic diagram of structure shown in Figure 1.
The specific embodiment
Introduce preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, this spinning low temperature extruder comprises feed system 10 and spinning system 20.
Wherein, feed system 10 comprises feeding motor 11, feed spool 12, feeding sprocket wheel 13, feed mechanism 14 and feed bin 15.Feeding sprocket wheel 13 is connected between feeding motor 11 and the feed spool 12, and the output of feeding motor 11 is delivered to feed spool 12, fixedly connected feed mechanism 14 on the feed spool 12, and feed mechanism 14 is erected to be arranged on the central authorities of feed bin 15.
Preferably, feed mechanism 14 comprises symmetrically arranged 2 the feeding wing plates 141 that are fixed on the feed spool 12, each feeding wing plate 141 profile curl, and in axial direction have certain length, play the effect of guiding feeding; Certainly, feeding wing plate also can be other suitable shapes in other embodiment of the utility model, and its number also can arrange a plurality of according to circumstances.The feeding structure of any suitable construction also can be used at this in the prior art.Among this embodiment, two feeding wing plates 141 form one, are nested in outside the feed spool 12, and feed spool 12 tops tighten cap 120 with feeding and tighten, so that feeding wing plate is fixed.
Wherein, spinning system 20 comprises spinning motor 21, spinning axle 22, spinning sprocket wheel 23, spinning wheel 24 and spinning chamber 25.Spinning sprocket wheel 23 is connected between spinning motor 21 and the spinning axle 22, and the output of spinning motor 21 is delivered to spinning axle 22, fixedly connected spinning wheel 24 on the spinning axle 22.Spinning chamber 25 is arranged on the bottom of feed bin 15 and is communicated with feed bin 15, is transferred the material that comes from feed bin 15 and is spun chamber 25 and accepts.In the present embodiment, spinning chamber 25 is built into by last spinning flange 252 and the backspin platen press orchid 253 of make-up, certainly, in other embodiment of the utility model, also can adopt any other suitable structure in the prior art.
Spinning wheel 24 is erected to be arranged on the central authorities in spinning chamber 25.Be provided with discharging opening 251 in the side in spinning chamber 25, discharging opening 251 arranges the orifice plate 2510 of inclination.Preferably, spinning wheel 24 comprises spinning base 241 and the spinning wing plate 242 that is erected to be fixed on the spinning base 241, and spinning base 241 is fixedly connected on the spinning axle 22, and spinning wing plate 242 adapts to spinning chamber 25 inwalls, with spinning material in spinning chamber 25.For strengthening the spinning effect, the gap arranges very for a short time between the outside of spinning wing plate 242 and the orifice plate 2510, and outer shape and orifice plate shape are adaptive.
For above-mentioned spinning motor 21 and feeding motor 11 are provided with motor mutual interlocking gear 30.
Preferably, above-mentioned spinning axle 22 is the cover tubular of hollow, and feed spool 12 passes the cavity of spinning axle 22 hollows and passes from the top, and the fixing above-mentioned feeding wing plate 141 in the position after passing.And above-mentioned spinning motor 21 and 11 outputs of feeding motor are reverse, the feasible spinning axle that is set-located 22 and feed spool 12 reverse rotations.
