Detailed description of the invention
Below in conjunction with the accompanying drawings and the present invention is described in further detail by specific embodiment.
With reference to Fig. 1, the present embodiment includes controller (not shown), storage tank 3, feeding screw 7, bucket 9, claims
Weight sensor 12 and blending bunker 14；The storage tank installing hole (not shown) that storage tank 3 is positioned on storage tank steel frame construction 1
In, it is attached by powder delivering pipe 2 between storage tank 3 and feeding screw 7, the charging aperture 8 of feeding screw 7 and powder
Conveying pipe 2 seamless link, the discharging opening of feeding screw 7 docks with the charging aperture 10 of bucket 9, the discharging opening 16 of bucket 9
Lower section is provided with conveyer belt 15, and conveyer belt 15 stretches in blending bunker 14.
Storage tank 3 is made up of charging aperture, warehouse, discharging opening 5 three part, and storage tank discharging opening 5 side is provided with pneumatic operated valve
4, control the opening and closing of the discharging opening 5 of storage tank.
Level detector 6 is installed on the outer wall of reserves tank 3, when the powder in storage tank 3 is less than level detector 6 sensed position,
Remind hand stock.Level detector 6 is connected with controller.
The charging aperture of feeding screw 7 and storage tank discharging opening 5 are by powder delivering pipe 2 vertical butt joint, the number of storage tank 3
Measuring identical with the quantity of feeding screw 7, each storage tank 3 is equipped with a feeding screw 7.The quantity of feeding screw 7 with
The quantity of bucket 9 is identical, and each feeding screw 7 is equipped with a bucket 9.
Bucket discharging opening 16 is provided with another pneumatic operated valve 13, and pneumatic operated valve 13 is for controlling the unlatching of bucket discharging opening 16
With closedown.Pneumatic operated valve 4 at storage tank 3 discharging opening 5 is all connected with controller with the pneumatic operated valve 14 of bucket 10 discharge outlet.
Bucket 9 inwall is provided with vibrator 11.Each bucket 9 inwall is equipped with a vibrator 11.By vibrator 11
It is easy to shake the formulation material on bucket 9 inwall fall on conveyer belt 15.
Described controller is existing controller.
Bucket 9 side is provided with LOAD CELLS 12.Vibrator 11 is all connected with controller with LOAD CELLS 12.
Bucket 9 is internally installed stirring mechanism so that powder can uniform rapid decrease.
Bucket 9 is located on material weighing device steel construction 16.
Feeding screw 7 is connected with servomotor, and feeding screw 7 uses servomotor to carry out high accuracy and drives control.
Servomotor is connected with controller.
Blending bunker 14 slant setting, in order to artificial from the discharging opening packaged formulation material of blending bunker.
Every kind of its formulation material composition of product is different, according to the kind of product, sets every kind of product correspondence in the controller
The kind of formulation material and weight, set force value and the drive parameter of servomotor of LOAD CELLS 12.When to start claiming
During weight, it is only necessary to select product category on the controller, controller can needed for this product of automatic identification and matching formulation material kind and
Weight, it is not necessary to manually again input.
Weighing-appliance is both placed in one layer, has the hole slot identical with storage tank 3 quantity, at two floors on two layers of bottom surface
Storage tank steel frame construction 1 is set below plate, storage tank steel frame construction 1 has the storage tank corresponding with two layers of bottom hole groove location
Installing hole, storage tank 3 is arranged in storage tank installing hole, the hole slot flush on the charging aperture of storage tank 3 and two layers of bottom surface.?
Two layers arrange a raw material silo, it is simple to manually put in storage tank 3 by material.The discharging opening 5 of each storage tank 3 is defeated by powder
Sending pipe 2 to dock with feeding screw charging aperture 8, after manually feeding intake at two layers, other flow process is all at a layer operation.
During device debugging, the powder weight that when determining feeding screw 8 every turn 0.1 circle, correspondence transmits；The most as required
Weighing the weight of powder, determine that this feeding screw 8 needs the number of turns rotated, therefore its conveying capacity of feeding screw 8 is controlled
, here we can realize the first time weighing of automatic batching system.If the pressure sensing being arranged on feeding screw
Device detects that the powder in feeding screw 8 exceedes setting value, needs manually unnecessary part to be scooped out.
Detailed process is as follows: when changing weighing product, under original state, storage tank discharging opening 5 is closed, feeding screw
7 reset, and bucket discharging opening 16 is closed, and the discharging opening of blending bunker 15 is closed.Spiral shell is come under formulation material vibration in storage tank 3
The charging aperture of rotation feed appliance 8, after feeding screw charging aperture 7 has experienced powder, feeding screw 7 is pushed away by the screw rod of self
Sending device that raw material is pushed into feeding screw discharging opening 7, the discharging opening of feeding screw docks with bucket 9 phase, and powder is from spiral shell
Rotation feed appliance discharging opening 7 enters in bucket 9, a corresponding bucket 9 of feeding screw 7.Title is entered into when there being powder
During hopper 9, the LOAD CELLS 12 of bucket side experiences signal, and each bucket configures a LOAD CELLS 12, when
When LOAD CELLS 12 senses the material reclosing nearly setting value in bucket 9, LOAD CELLS 12 can return a signal this moment
To controller, controller feeds back signal to servomotor so that feeding screw 7 slows down feeding speed, meanwhile, passes through controller
Make storage tank discharging opening pneumatic operated valve 4 close, so that the discharging opening 5 of storage tank 3 is closed, fall without powder after closedown.Work as pressure
Force transducer 12 senses when the weight in bucket 9 reaches target set point, LOAD CELLS 12 feedback signal to controller,
Controller makes feeding screw 8 stop feeding by stopping servomotor, and the bucket 9 of this feeding screw 7 correspondence is no longer
Powder is had to enter；When all kinds material weigh complete errorless after, opened the gas of all bucket 9 discharge outlet by controller
Dynamic valve 13, entirely falls in the material in bucket on conveyer belt 15, concentrates and is transported to blending bunker 14 by conveyer belt 15.Blending bunker
14 slant settings, formulation material is from the inner outflow of blending bunker 14.Artificial from blending bunker discharging opening packaged formulation material.
