Embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast description of drawings embodiment of the present utility model:
At first, see also shown in Fig. 1~4, be weight-loss type continuous measurement platform scale schematic representation of apparatus of the present utility model, it mainly is provided with the main stand 1 that an inside is divided into upper and lower layer 11,12, be provided with metering platform scale group 2 more than one group in main stand 1 internal frame, supply working machine 3 runnings via the discharging opening 13 of main stand 1 lower floor 12 and respectively measure platform scale group 2 corresponding transferring raw materials, wherein this metering platform scale group 2 includes:
One storage vat 21, correspondence is arranged at the upper strata 11 of main stand 1, for storing storage barrel via the storage raw material of vacsorb, and its storage vat 21 is provided with the particle collector 211 of a processing raw material dirt ash and air separation, and storage vat 21 belows are provided with a material controlling valve 25, open storage vat 21 in order to control and make raw material fall into metering charging basket 22;
One metering charging basket 22, correspondence is arranged at the lower floor 12 of main stand 1, and storage vat 21 outlets further connect binding by a soft external member 26;
At least three loading elements 23, correspondence be set up in metering charging basket 22 around, be suspended on main stand 1 crossbeam and will measure charging basket 22, and detect the interior material quantitative changeization of metering charging basket 22 with supported at three point;
One feed screw machine 24, correspondence are mounted on the exit of metering charging basket 22, and it is provided with a power source 241 and drives screw rod 242, and the screw rod 242 delivery raw materials of making way in the delivery pipe 243 are supplied to working machine 3 via the discharging opening 13 of main stand 1 lower floor 12.
Whereby, material vacuum is attracted in the storage vat 21, when metering charging basket 22 is in the state of weightlessness of low level, open material controlling valve 25, make additional the falling into of raw material in the storage vat 21 carry out suitably replenishing raw material in the metering charging basket 22, via the speed of respectively measuring platform scale group 2 corresponding feed screw machines 24 on the main stand 1, calculate the weight that falls in the metering charging basket 22 again, reach with the automatic suction of vacuum attraction raw material and the combination of weight-loss type continuous measurement platform scale by loading element 23.
See also Fig. 1~shown in Figure 4, when the utility model uses, equipment via vacsorb attracts raw material to deposit in the storage vat 21 in advance, and the attraction process while handles via the dust-collector that the particle collector on the storage vat 21 211 carries out raw material dirt ash and air separation; And give the metering charging basket 22 of working machine 3 runnings (carrying out plastics extrusion processing) as extruder for supplying raw material, when the raw material in the metering charging basket 22 arrives the state of weightlessness of low level, open material controlling valve 25, fall in the metering charging basket 22 with the junction that connects of measuring charging basket 22 to allow storage vat 21 interior raw materials be socketed on storage vat 21 via soft external member 26 correspondences, and its soft external member 26 can prevent blanking the time dust leak, and in blanking, via being set up in metering charging basket 22 loading element 23 on every side, detect the material quantitative changeization of measuring in the charging basket 22 with supported at three point, make it under the state that working machine 3 operates simultaneously, can be correctly and the various different material dosage of continuous supplementation in the metering charging basket 22 of each metering platform scale group 2; In addition, because of the required ratio difference of each raw material, therefore the metering charging basket 22 required benefits of each metering platform scale group 2 claim that the time of raw material is also different, so, be positioned at each metering charging basket 22 loading element 23 on every side, via additional control and the calculating of an electronic control system 4 amounts of expecting, with the shortest time blanking to measuring in the charging basket 22, so can in the fixing short time of setting, finish feed supplement, can significantly reduce the existing platform scale feed supplement process of tradition, provide fixed volume formula flow after feed supplement is finished, to measure with the weight-type platform scale again according to account keeping way, so can significantly improve its measuring accuracy, unmanned again scarce material and the specification that produces for operation is incompatible, various combination and the inadaptability that produces, owing to be the integrated design, can reduce to pollute producing and cost waste.
Continue, after raw material falls into metering charging basket 22, drive screw rod 242 by feed screw machine 24 with power source 241, and allow the delivery pipe 243 interior screw rod 242 delivery raw materials of feed screw machine 24 be supplied to working machine 3 via the discharging opening 13 of main stand 1 lower floor 12; In addition, when too much or density is high when raw material, it can use the double helix mode to cooperate the design of the different pitch of front and rear sections screw rod 242, leading portion is positioned at metering charging basket 22 for being to be used for quantitatively exporting than fine pitch, then to be positioned at the delivery pipe 243 of feed screw machine 24 be to be used for making raw material loose for the pitch that extends to section, reduce and to push and the formation of false knot piece, because the material density in the loose reduction delivery pipe 243 of raw material and two thread function can increase the stability of operational throughput, therefore, can significantly improve the precision of platform scale; Also can be provided with stirring machine 27 corresponding auxiliary material outputs simultaneously according to property of raw material, promptly be erected on the feed screw machine 24, between metering charging basket 22 and feed screw machine 24, stirring machine 27 drives a puddler 272 by a power source 271, and this puddler 272 is Z-shaped design, can assist feed screw machine 24 transferring raw materials by the setting of stirring machine 27, to improve the false knot piece that produces because of extruding, reaching the bridge formation cavitation influences feed screw machine 24 feeding unevenness, and the metering instantaneous variation that causes.
The above only is the schematic embodiment of the utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, equivalent variations of having done under the prerequisite that does not break away from design of the present utility model and principle and modification all should belong to the scope that the utility model is protected.
