Detailed description of the invention
Below in conjunction with drawings and Examples this utility model it is further elaborated and illustrates.In this utility model, the technical characteristic of each embodiment is not under having conflicting premise, all can carry out respective combination.
Of the present utility model automatically control microweigh system and method operation principle be: gear diameter and its lower portion are tangent, and when gear stationary, sample will be stored in application of sample funnel；When gear starts to rotate, the gap that sample will pass through between gear enters sample cup, by controlling rotation status and the resting state of gear, it is achieved that the required precision of sample microweigh；Launch signal by controller gear rotation status or resting state are controlled, it is achieved that trace controls the automatization with precision controlling.
As illustrated in fig. 1 and 2, a kind of automatic fine Weighing system, including application of sample funnel 2, gear 3, controller 4, dodge gate 5, sample cup 6, gravity sensor 7, base 10, shell 11.For the base 10 for supporting bottom shell 11.Shell 11 is provided with handle 1.It is internal that application of sample funnel 2 is arranged at shell 11, and application of sample funnel 2 top communicates with the external world, as charging aperture.The sample cup 6 accepting material it is provided with bottom application of sample funnel 2.The material that filler neck falls is directly entered in cup 6.As it is shown on figure 3, application of sample funnel 2 cervical region is provided with the gear 3 being controlled rotation by controller 4.Gear 3 and application of sample funnel 2 cervical region interference fit, application of sample funnel 2 cervical region is preferably with the preparation of somewhat resilient, and airtight between gear 3 both sides and filler neck, and its relative one or more pairs of gear teeth connect with the both sides of filler neck simultaneously, it is achieved seal.Thus, the material in application of sample funnel 2 horn mouth, when gear does not rotate, is completely blocked above gear 3；When gear 3 rotates, the material in application of sample funnel 2 horn mouth is carried secretly to gear by the teeth groove in the middle of two gear teeth and is fallen in sample cup 6.Sample cup 6 correspondingly can be changed according to requirement of experiment.
Sample cup 6 is arranged below gravity sensor 7, for the quality increased in sample cup 6 is measured.By accumulator 12, whole device is powered bottom shell 11, it is possible to adopt alternating current to be powered.
Transparent removable panel is preferably stamped at application of sample funnel 2 top；When needing charging, open removable panel, it is not necessary to during charging, be turned off, it is prevented that dust falls into.
In order to realize Automated condtrol sum factually time display, shell 11 also can be provided with display 8 and control panel 9, control panel 9 is for inputting aimed quality to be weighed according to user's request to controller 4；Display 8 is for showing aimed quality to be weighed and current Quality.Gravity sensor 7 result of variations by Dynamic Announce in display 8.
The running of said apparatus is:
1) add the sample cup 6 being consistent with requirement of experiment size in the apparatus, and remove the peel on control panel 9；2) open the movable panel at shell 11 top, weighed amount sample is poured in application of sample funnel 2, then by shell 11 top seal；3) the concrete Accuracy Figure of the required sample of input on control panel 9；4) signal is sent to controller 4 by control panel 9, and controller 4 controls gear 3 and starts to rotate, and now the space in rotating along with gear 3 is entered in sample cup 6 by the sample in application of sample funnel 2；5) gravity sensor 7 is by the Gravity changer of sensing sample cup 6, and its result is shown on display 8；6) when result is close with the concrete Accuracy Figure of the required sample of input on control panel 9 on display 8, launching signal to controller 4, controller 4 controls gear 3 rotary speed makes it slowly rotate, it is ensured that the realization of weighing precision；7, when result is identical with the concrete Accuracy Figure of the required sample of input on control panel 9 on display 8, will launch signal to controller 4, and controller 4 controls gear 3 and stops the rotation, it is ensured that realize while weighing size and precision；8) dodge gate 5 is opened, take out sample cup 6, obtain satisfactory sample；9) application of sample funnel 2 and gear 3 can be cleaned, and make gear 3 rotate when n.s, reach the purpose of cleaning.
Owing to needs are often sampled, therefore sample cup 6 is designed as detachable block, and is additionally provided with dodge gate 5 on shell 11；When needing to change the sample cup 6 of correspondence along with weighing precision, dodge gate 5 can be opened sample cup 6 is replaced.
In order to realize the precision needed for weighing process, the selection standard of gear 3 is: in gear 3 rotary course, and the quality of material that the teeth groove in the middle of two gear teeth can be carried secretly is not more than weighing precision.If condition is not satisfied, in fact it could happen that weigh not enough or excessive situation.
Based on said apparatus, this utility model additionally provides a kind of automatic fine weighing technique utilizing described system, and step is as follows:
Control panel 9 sends aimed quality data to be weighed according to user's input to controller 4；Controller 4 controls gear 3 after receiving data when rotating, the material in application of sample funnel 2 horn mouth is made to be carried secretly to gear and fall into by the teeth groove in the middle of two gear teeth in sample cup 6, and sense by gravity sensor 7 whether the quality increased in sample cup 6 reaches aimed quality to be weighed in real time, when reaching wait the aimed quality weighed, stopping pinion rotation, weighing terminates.
In order to save the weighing time, when gear 3 just starts to rotate, rotate with speed faster, when gravity sensor 7 senses that the quality increased in sample cup 6 reaches wait the preset ratio of the aimed quality weighed, reducing the velocity of rotation of gear 3, terminating until weighing.And this ratio can be set by user oneself, it is possible to be arranged to the charging of many stage progressives.Namely arranging multiple weighing section, after reaching certain proportion, slow down corresponding speed.
Embodiment described above is one of the present utility model preferably scheme, so itself and be not used to restriction this utility model, all take equivalent replacement or technical scheme that the mode of equivalent transformation obtains, all fall within protection domain of the present utility model.
