Description
Technical field
The utility model relates to a kind of Novel double-screw extruding machine feed arrangement.
Background technology
Bitruder pours in extruder by master batch, through heating and melting, twin-screw extrusion, then measure through measuring pump, extrude through mould again thus form certain thickness sheet material, sheet material is again through carry-over pinch rolls roll-in, traction, rolling, and the sheet material made like this can be used for automotive upholstery etc.
At present, Bitruder feed arrangement comprises feed hopper.Manually directly pour in feed hopper by material, material enters in Bitruder again.Easily there is clogging in such one side, on the other hand, hand feed efficiency is low.
Utility model content
For existing problem, the purpose of this utility model is the Novel double-screw extruding machine feed arrangement providing a kind of powder feeding efficiency high.
To achieve these goals, the technical solution of the utility model is: a kind of Novel double-screw extruding machine feed arrangement, comprise feed hopper, it is characterized in that: above twin-screw extrusion machine inlet capable, feeding cylinder is set, the below of described feed hopper arranges spiral propeller, discharging opening below described feed hopper is connected with the charging aperture of spiral propeller, and the discharging opening of described spiral propeller is connected with the sidewall of feeding cylinder;
The upper end of described feed hopper is provided with cover plate, described cover plate is provided with little hopper, discharging opening below described little hopper communicates with feed hopper, the discharging opening of described little hopper is provided with by-pass valve control, and described little hopper upper end is provided with seal cover board, and described seal cover board is provided with bleeding point, described bleeding point is provided with exhaust tube, described bleeding point is provided with screen pack, and the sidewall of described little hopper is provided with charging aperture, and described charging aperture is provided with feed pipe.
Adopt such scheme, charging aperture arrange feeding cylinder, convenient to be connected with spiral propeller, set up spiral propeller, make material from feed hopper out time not easily block.
In addition, we arrange little feed hopper above feed hopper, the exhaust tube of little feed hopper is connected with vavuum pump, and feed pipe is connected with the sack or material temporary storing bin filling material, utilizes to vacuumize to be extracted in little hopper by material, when material is taken out full, stop vacuumizing (by the time controling vacuumized, this control program is this area routine techniques), then control by-pass valve control and open, material is put into feed hopper, the trouble of hand stock can be saved like this.And adopt little hopper to take out material, bucket capacity is little, and vacuum easily reaches, and energy consumption is low.Arranging of filter screen can avoid material to be extracted in vavuum pump, and cause vacuum pump evacuation effect bad, service life is short.
In such scheme: the lower sides of described feed hopper is provided with observation window.The material situation inside hopper can be observed like this.
In such scheme: the upper end of described feeding cylinder is provided with upper cover plate.
The beneficial effects of the utility model are: the utility model sets up spiral propeller below feed hopper, avoid the phenomenon of feed blocking, and adopt little hopper to vacuumize charging, little bucket capacity is little, and vacuum easily reaches, and energy consumption is low, eliminates the trouble of hand stock.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Embodiment 1
As shown in Figure 1: novel Novel double-screw extruding machine feed arrangement of the present utility model comprises twin-screw extrusion machine inlet capable and feed hopper 1, and above twin-screw extrusion machine inlet capable, arrange feeding cylinder 2, the upper end of feeding cylinder 2 is provided with upper cover plate 21.The lower sides of feed hopper 1 is provided with observation window 10.The below of feed hopper 1 arranges spiral propeller 3, and spiral propeller 3 comprises screw sleeve, pushing screw rod and motor, is provided with charging aperture on the upside of the middle part of screw sleeve, and this is prior art, does not repeat at this.Discharging opening below feed hopper 1 is connected with the charging aperture of spiral propeller 3, and the discharging opening of spiral propeller 3 is connected with the sidewall of feeding cylinder 2.Owing to having set up spiral propeller 3, therefore, feed hopper 1 is difficult to realize sealing, on feed hopper 1, directly vacuumize charging energy consumption high, and effect is bad.Therefore we are provided with cover plate 4 in the upper end of feed hopper 1, cover plate 4 is provided with little hopper 5, discharging opening below little hopper 5 communicates with feed hopper 1, the discharging opening of little hopper 5 is provided with by-pass valve control 6, little hopper 5 upper end is provided with seal cover board 51, seal cover board 51 is provided with bleeding point, bleeding point is provided with exhaust tube 8, exhaust tube 8 is connected with vavuum pump by pipeline, bleeding point is provided with screen pack 9, avoid in material suction vavuum pump, the sidewall of little hopper 5 is provided with charging aperture, and charging aperture is provided with feed pipe 7.
By-pass valve control 6 and vavuum pump are controlled by switch board, gap charging and discharging, and namely by the setting of time, vavuum pump first vacuumizes charging, and then time is up opens by-pass valve control 6 blowing, and then charging so circulates.This control method is this area routine techniques.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
