The specific embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this description.
Refer to Fig. 1 to Fig. 2.Notice, appended graphic the illustrated structure of this description, ratio, size etc., all contents in order to coordinate description to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
If figure is with as shown in the of 1 to Fig. 2, the utility model provides a kind of extruder batching mixing arrangement, comprises weighing silo, weighing device 3, drawing-in device 4, blending bunker 5.Weighing silo of the present utility model comprises a major ingredient storehouse 1 and two auxiliary material storehouses 2, and major ingredient storehouse 1 is for depositing major ingredient, and auxiliary material storehouse 2 is for depositing auxiliary material; On each major ingredient storehouse 1 and auxiliary material storehouse 2, be equipped with a weighing device 3, weighing device 3 is installed on the barrel of weighing silo, one side is connected with weighing silo, opposite side is connected (shown in Fig. 2) with a frame, in weighing device 3, be provided with LOAD CELLS, LOAD CELLS is for detection of the actual flow of raw material in weighing silo, and exports actual flow signal to controller.Drawing-in device 4 is arranged on below, auxiliary material storehouse, and is single screw rod drawing-in device, is connected with the discharge gate 21 in auxiliary material storehouse; Blending bunker 5 is arranged on 1 below, major ingredient storehouse, and blending bunker 5 has separate major ingredient passage 51 and auxiliary material passage 52, and major ingredient passage 51 is connected and communicates with the discharge gate 11 in major ingredient storehouse, and auxiliary material passage 52 is connected and communicates with the discharging opening 41 of drawing-in device; Blending bunker bottom is connected with extrusion main unit 6, and major ingredient passage and auxiliary material passage are connected to the feeding mouth of extrusion main unit jointly, and major ingredient and auxiliary material respectively by independently passage conveying, are realized nature at the feeding mouth place of extrusion main unit raw material and mixed in mixing bunker.
