Auxiliary device that accuracy is weighed adds there is controlling means, it is rotatory to drive the lead screw through the knob on the spin control device, thereby make and slide along the guide rail with the rotatory complex baffle of lead screw, change the area of contact of gear shifting board and discharging device discharge gate tip, the realization reduces the material flow near weighing the value on schedule, make the knob be in the closed condition when reaching predetermined numerical value, avoid getting the material and frequently open the shell side door too much or too little the time, the precision of weighing has been improved, the error influence of environment change has been reduced.
Description
Technical field
The utility model relates to meausring apparatus, particularly relates to a kind of servicing unit of accurate weighing.
Background technology
Weighing is very important a kind of characterization method, is widely used in the every field of the national economic development.A lot of problem is there is in current existing analytical balance for powder weighing, when the powder weighed is close to setting numerical value, often too much or very few with getting thing bale-out material, now just need frequently to open shell side door, lengthen the weighing time, if have dust or wind-force to enter, then can cause certain error.Chinese utility model patent CN2301711Y discloses a kind of meausring apparatus, this device comprises shell, be arranged on feeding device on shell, control the switch of feeding device, tipping bucket, infrared control device and weighing device, weighing process breaker in middle just for controlling the reinforced beginning of feeding device and complete, when splicing in tipping bucket quality and alleged be equal in weight time, infrared induction Received signal strength on balance, feed back to switch, switch ability rapid closing, weighed object could be translated in container by tipping bucket, complete and once weigh, received by infrared induction, the interval time that feedback signal is carried out the closed of gauge tap and opened, and then the time that control once weighs.The switch of this device only has to be opened and completely closed two states completely, in weighing process, switch closed always quality reach weigh equal time, ability feedback signal, and the switch response speed of closing and closing speed all affect the precision of weighing, comparatively high product is required for weighing precision, larger error can be produced.
Utility model content
The utility model object is to provide the servicing unit that a kind of error is little, can control the accurate weighing of powder flow.
For achieving the above object, the interconnected stationary installation of the utility model adopts following technical scheme:
The servicing unit of accurate weighing comprises shell, feeding device, weighing device, discharging opening is provided with bottom feeding device, also comprise the control device controlling discharging opening and open and close, this control device have coordinate with discharging opening for control mass flow baffle plate, for baffle plate move slide guide rail, for moving stop leading screw and be arranged on sidewall and drive baffle plate to open the knob of discharging opening for rotating threaded shaft.
Described leading screw is threaded with adopting between baffle plate.
Described feeding device is charging hopper.
Described charging hopper is conical funnel.
Charge door above described feeding device is provided with dust cap.
Described guide rails assembling is between two of shell relative sidewalls
Advantageous Effects of the present utility model is: the servicing unit of accurate weighing is added with control device, leading screw is driven to rotate by the knob on rotating control assembly, thus make with the baffle plate of leading screw rotatable engagement along slide, change the contact area of baffle plate and drawing mechanism discharging opening end, weighing thing discharging flow carries out stability contorting, realize reducing mass flow near predetermined weighing value, make knob be in closed condition when reaching predetermined value, avoid feeding too much or very few time frequently open shell side door, improve the precision of weighing, reduce the error effect of environmental turbulence.
