Abstract
The utility model provides an automatic scale for powder particle materials for quantitative measuring powder particle materials, which is characterized in that the utility model is composed of a material storage bin, a material feeding tray, a weighing device and a transition bracket. The weighing device is composed of two identical containing cups and two identical measuring hoppers, the two containing cups is fixedly connected with the material feeding tray, and a tray with a valve is arranged at the lower part of the material feeding tray. The two measuring hoppers are connected with respective weighing sensor, the measuring hopper is also provided with a measuring hopper door, and the upper openings of the two measuring hoppers are respectively provided with a micro material feeder.
Description
The utility model relates to a kind of automatic balance of weigh, especially a kind of automatic balance that is used for the weighing powder and granule shape material.
In the prior art, the weighing powder and granule shape material generally adopts the quantitative and quantitative two kinds of metering methods of weight method of volumetric method.Volume quantitative method cost simple in structure is low, owing to be by holding the how much next quantitative of wine material, so its metering speed is very fast, but the accuracy of its metering is lower, be generally ± 3-5%, it is more even only to be suitable for material density, and the less demanding occasion of the accuracy of measuring.The sizing technique of weighing can have the higher accuracy of measuring, can reach ± 0.1% accuracy, but because the restriction of little dispenser feed and sensor response time, feed can not be too fast, so make its metering speed slower, be applicable to require accuracy of measuring height the uneven quantitative weighing of material density.Most powder and granule shape materials in process of production, be subjected to all multifactor influences such as raw material, prescription and technological operation, its product density is difficult to stable, quantitative package adopts volumetric method quantitative, and speed is with soon, but its measuring accuracy is too poor, if adopt weight method quantitative, the measuring accuracy of weight can be guaranteed, but all too is slow again for the speed of its metering, and this is a pair of insoluble contradiction.
The purpose of this utility model is exactly at existing in prior technology contradiction, and provides a kind of metering speed very fast, and can guarantee the powder and granule shape material automatic balance technical scheme that measuring accuracy requires.
For clearly demonstrating the technical characterstic of this programme,, and, this programme is described in detail in conjunction with its accompanying drawing below by a specific embodiment.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 looks synoptic diagram for the right side of Fig. 1;
Fig. 3 overlooks the part cross-sectional schematic for Fig. 2's.
In the accompanying drawings as can be seen, the powder and granule shape material automatic balance of this programme has a storage bin hopper 7 and to delivery plate 8 feed, is measured by weighing device again, then the material that measures is defeated by transition bucket 1 output, enters next procedure.Described weighing device is made up of with two identical weighing hoppers 12 two identical appearance cups 9, described two are held cup 9 and fixedly connected with a delivery plate 8, it is next to be one to have the pallet 15 of a valve 10, two identical appearance cups 9 are the adjustable Adjustable Capacity cups of volume, quantitative by its volumetric method that carries out material, and provide rough quantitatively.Described two weighing hoppers 12 are connected with separately LOAD CELLS 4, and are quantitative in order to carry out weight method, and provide accurate metering.On weighing hopper 12, measure sluice gate 13 in addition, a little loader 6 is then respectively arranged, and, small volume feeding is provided for weighing hopper 12 by little loader 6 by storage bin hopper 7 feed in upper shed place of two weighing hoppers 12.Metering sluice gate 13 on described weighing hopper 12, be to be connected with the push rod 11 that opens the door, at a side of the push rod 11 that the opens the door cylinder 3 that opens the door, in order to back down metering sluice gate 13 by the pull bar 14 that opens the door, in addition, on the push rod 11 that opens the door, close the door extension spring 2 be used for closing the metering sluice gate 13.In addition, the rotating shaft 16 of described delivery plate 8 is to be connected with a rotating shaft cylinder 5 by connecting rod, makes rotating shaft 16 drive delivery plate 8 and does back and forth to rotate, to guarantee holding cup 9 feeds to two.
Pass through said structure, can learn clearly that this programme is that to carry out volumetric method quantitative by holding cup, come material is done rough metering with the volumetric metering method, then, material enters weighing hopper, adjust by little loader feed, carry out accurately the Weighing method by LOAD CELLS and measure, and can obtain quantitative comparatively exactly.Weighing hopper except that with LOAD CELLS be with the external world exist be connected, the switch part of other metering sluice gate all is on weighing hopper, there is not annexation with the external world, being used for backing down the cylinder that opens the door that measures sluice gate also only just contacts with the push rod that opens the door when back pullout (BPO) is finished in metering, so the measuring fixed amount of weighing hopper is very accurate.In addition, this programme is made up of the identical measuring apparatus of two covers, slightly measure to intersect and carry out with accurate measurement, when a covering device slightly measures, another set of device is then carrying out accurate measurement, and when thick metering, can finish a large amount of feed processes fast, during to accurate measurement, then only need finish the few material of residue and replenish, so improved metering speed greatly, realized making volumetric method quantitatively with quantitative the combining of weight method, utilized the advantage of the two, overcome the shortcoming of the two, reached fast and measure with accurate.This shows that the utility model compared with prior art has substantive distinguishing features and progressive, its implementation result also is conspicuous.
