3rd, sealed using Glais ring between rotary sleeve and transition piece and rotary sleeve base, can at any time to relative rotation
Abrasion between contact surface carries out backlash compensation, and material leaks outside from the contact surface for relatively rotating in preventing blanking operation；
4th, the setting in the gap between first annular boss, the second annular boss and rotary sleeve, and the second annular boss
Side wall on through hole setting, in the blanking operation of system, can be by through hole to first annular boss, the second annular boss
Compressed air is passed through in gap between rotary sleeve, so as to right between rotary sleeve and transition piece and rotary sleeve base
The place of connecing forms hermetic seal, and material will not leak outside from joint in being further ensured that blanking operation；
5th, the setting of the gap of the arc on blowing baffle plate, even if making the small unlatching of tapping hole, the gap and blowing of arc
Can also be formed between the inwall in hole similar to oval material channel, a small amount of, micro material blanking be realized, so as to be conducive to
Accurate dispensing, compared to the blowing baffle plate of other edge shapes, can be prevented effectively from the small unlatching of tapping hole not blanking, open big
Uncontrollable situation blanking amount occurs again；
6th, the setting of connecting cylinder and telescopic cylinder, covers by the expanding-contracting action of telescopic cylinder, the upper end of connecting cylinder
In the outside of discharge barrel, the inner side of the material inlet of turnover charging basket is stretched into the bottom of connecting cylinder, is conducive to material successfully to fall into
Turnover charging basket；
7th, material is blown out from the material inlet of turnover charging basket during the setting of closure can tentatively avoid blanking operation, annular
The setting of aerofoil, annular chamber and exhaust tube is crossed, in blanking operation, negative pressure source can be connected by exhaust tube, made in annular chamber
In negative pressure state, annular chamber is inwardly evacuated by the through hole that annular is crossed on aerofoil, so as in the import of turnover charging basket and sealing
Air-flow from the outside to the core is formed at gap at gap between lid and between discharge barrel and connecting cylinder, is further ensured that and
During material, material will not blow out to external working environment from the two gaps.

Side, and make the upper wall of the one-level step of the upper end of the material inlet of turnover charging basket and closure and annular cross aerofoil between leave between
Gap, being acted by the action control blowing baffle plate of the piston rod of multipoint positioning cylinder fully opens tapping hole, and quick blowing is treated
When blowing amount is close to required dosage, controlling multipoint positioning cylinder to act by the feedback signal of electronic scale makes tapping hole
Close, then carry out blowing compensating movement, each blowing compensating movement makes tapping hole small area open and close once, and blowing amount is fixed,
By multiple blowing compensating movement, blowing amount is set to reach required dosage, blowing compensating movement terminates, it is generally the case that
In once blending process is weighed, using two-stage blowing compensating movement, the blowing amount of two grades of blowing compensating movements is very small, remote low
In the blowing amount of one-level blowing compensating movement, when making overall blowing amount further approach weighing by one-level blowing compensating movement
It is required that when, using two grades of blowing compensating movements, blowing amount is reached required dosage.During whole blowing, by electricity
Machine control rotary sleeve drives broken bridge bar to rotate material toggling, prevents material from being lumpd in blanking operation, put up a bridge.During whole blowing,
The compressed air source that the through hole on the side wall with the second annular boss is connected and the negative pressure source connected with exhaust tube are opened, is existed respectively
Between rotary sleeve and transition piece and rotary sleeve base and turnover charging basket import and closure between gap at and go out
Hermetic seal is formed at gap between barrel and connecting cylinder, material leaks outside or blow out everywhere more than during preventing blowing.
The present invention, can be using a turnover charging basket and multiple proportioners with the use of (every in actual application
The material held in the storage vat of individual proportioner is different), so as to rapidly realize that the mixing of various materials weighs dispensing, turnover
Transfer of the charging basket between each proportioner can be realized by moving cart.
