Detailed description of the invention
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, the present invention includes the hollow barrel 2 of the equal opening in two ends, be provided with heater in described barrel 2 outer wall, it is characterized in that, also comprise:
-screw rod 4, to be arranged in barrel 2 and to be driven by power set and rotate, and described screw rod 4 comprises and being symmetrical arranged and the contrary two sections of points of bodies of rod 5 of hand of spiral;
-hopper 6, is provided with the cavity volume for placing material, and described hopper 6 is at least provided with two and center line along described screw rod 4 is symmetrical arranged, and the cavity volume of described hopper 6 is communicated with the hollow lumen of described barrel 2;
-material blanking tube 8, is at least provided with two, and all with the inner space of described barrel 2, described material blanking tube 8 is between described hopper 6;
-blanking switch 10, for controlling opening or cutting out of described material blanking tube 8.
As a further improvement on the present invention, described blanking switch 10 is connected with a controlling organization, described controlling organization comprises LOAD CELLS 12 and time-delay relay 14, when being positioned at described material blanking tube 8 and being inner and material above blanking switch 10 reaching setting value, control described blanking switch 10 to open, the timing of described time-delay relay 14, to setting-up time, controls described blanking switch 10 and closes simultaneously.
As a further improvement on the present invention, be provided with in the middle of described barrel 2 and hold described screw rod 4 and pass, and by partition 16 that the inner chamber of described barrel 2 separates.
