Detailed description of the invention
Below detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises the hollow barrel 2 of the equal opening in two ends, is provided with heater, it is characterized in that, also comprise in described barrel 2 outer wall:
-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 further improvement of the utility model, 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 further improvement of the utility model, 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.
As further improvement of the utility model, described partition 16 is rolling bearing, and the outer ring of described rolling bearing and inner ring are separately fixed on the inwall of described barrel 2 and the outer wall of screw rod 4.
Principle of the present utility model is as follows:
(1) material is placed in the cavity volume of hopper 6, and falls under gravity in the inner chamber of material pipe;
(2) when screw rod 4 rotates in barrel 2, plastic grain in barrel 2 is involved in the screw channel of screw rod 4, and is progressively melted, compacting, exhaust;
(3) liquid material in material pipe, under the effect of screw rod 4, drops into material blanking tube 8 gradually;
(4) the quantitative mixing of material is realized by blanking switch 10, every root material blanking tube 8 is equipped with LOAD CELLS 12, a fixing value is set to the LOAD CELLS 12 on every root material blanking tube 8, when material accumulative in material blanking tube 8 reaches setting value, LOAD CELLS 12 can be opened, material is opened, drop in space below, mix, in addition, LOAD CELLS 12 is also electrically connected with time-delay relay 14, this time-delay relay 14 is for controlling the opening time of material blanking tube 8, to ensure, it is have time enough that material falls.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
