It wraps up in, powder is thrown away from scoop group valence and sheath body 5 rear to be slid along the gather materials inside of cover 32 of weighing into the scale pan 33.
The course of work of the present invention：
1) powder is loaded into the vessel of scoop component：
The first drive component 1 in first feeding material component 36a drives adjusting part 3 to be rotated, adjusting part 3 by with
Relative motion between adjusting nut 27 makes adjusting part 3 that can be revolved according to the motor in the first drive component 36a along guide sleeve 35
To different ascending, descending is done respectively move.Adjusting rod 11 in scoop component 4 is connected with the attaching nut 18 in adjusting part 3, works as tune
When moving downward, the adjusting rod 11 in scoop component 4 declines section component 3, by piston rod connecting plate 6, piston rod positioning plate 7 with
The piston rod 8 that adjusting rod 11 is connected also simultaneously declines.The motor of second drive component 2 rotates, and is driven by first gear 16
Bowl 10, piston rod 8, sheath body 5 rotate integrally, and a vessel in the first feeding material component 36a is directed at sending for feed mechanism 37
Hopper 371, feed mechanism 37 start to feed to vessel 9, and when often filling a vessel 9, the motor of the second drive component 2 revolves again
Turn, so that the alignment alignment feed mechanism 37 of next vessel 9 is exported, feed to next vessel 9.During this, powder meeting
It in the presence of spilling situation, and there are powder heap protuberance or is scattered in bowl 10 after vessel 9 fills material, needs to start at this time
The motor of second drive component 2 rotates, and scoop component 4 is driven to rotate integrally, and by centrifuging force effect, heap is swelled or is scattered in
Powder in bowl 10 is thrown away, make on scoop component 4 only have vessel 9 in have powder.Spilling material in charging process and more
The powder gone out is collected into along the clout cover 381 that gathers materials in clout catch tray 382.
2) Switch of working position：
Lifting is filled the first feeding material component 36a, the second feeding material component 36b, 39 integral lifting of rotating device, rotating device 39
(spinning movement is carried out again, the position of the first feeding material component 36a, the second feeding material component 36b are switched over, so that vessel 9 is filled and waits for
The first feeding material component 36a of powder is claimed to be in weighing station, the second feeding material component 36b is in dress powder station.Lifting gear 40 is again
By the first feeding material component 36a, the second feeding material component 36b, 39 entire lowering of rotating device, the second feeding material component 36b is in be installed
First feeding material component 36a is in state to be weighed by powdery state.
3) powder is weighed quantitative automatically：
The first drive component 1 in first feeding material component 36a drives adjusting part 3 to be rotated by second gear 21,
Adjusting part 3 makes tune by the relative motion between adjusting nut 27, according to the motor rotation direction difference in the first drive component 1
Section component 3 does ascending, descending campaign respectively along guide sleeve 35.Adjusting rod 11 in scoop component 4 and the attaching nut in adjusting part 3
18 are connected, and when adjusting part 3 moves upwards, the adjusting rod 11 in scoop component 4 rises, and passes through piston rod connecting plate 6, piston
The piston rod 8 that bar positioning plate 7 is connected with adjusting rod 11 also rises along vessel 9 simultaneously, and piston rod releases powder in vessel.With
This simultaneously, the motor of the second drive component 21 drives bowl 10 and sheath body to rotate integrally by first gear 16, passes through centrifugal force
Effect, the powder for being higher by vessel 9 is thrown away, the powder that throws away is dropped into along the cover 32 that gathers materials of weighing on the scale pan 33.Weighing instrument 34
The weight and situation of change of the scale pan 33 are monitored, change promotion speed, the position of adjusting rod 11 according to required weight
Determine the speed to introduce and released amount of powder in vessel 9, it is quantitative to automatically accurately export and weigh powder.
