Compared with prior art, technical solutions of the utility model the utility model has the advantages that
1, when weighing powder, powder pours into the utility model from feed inlet, and bag clamping device accompanies the sack of dress powder.Powder
Before pack, two opening-closing sheets are fully open at end, and bag clamping device clamps sack and discharge port is close to sack bottom, are packed into powder
During sack, bag clamping device is clamped sack under the drive of vertically movable mechanism and is moved down, make discharge port and sack it
Between remain shorter distance, reduce the dust that powder generates in bagging process, improve the precision of weighing.
In the pack that the early period of powder pack is constant volume, when vertically movable mechanism controls bag clamping device is high in certain decline
When spending, the control of powder in sack in the weight for being lower than setting value, thus, two opening-closing sheets are standard-sized sheet, accelerate powder and pour into
Speed.When bag clamping device drops to certain height, one of opening-closing sheet is closed, and Weight detecting device starts to incude bag
The weight of son, another opening-closing sheet realization is closed step by step, until finally completely closing.By the closing step by step of multistage opening-closing sheet, just
Weighing when powder in sack is close to setting value, improves the weighing accuracy of powder, improves the weighing efficiency of powder, by
No aerial material is weighed in the constant volume of leading portion, aerial material when back segment is by Weight detecting device induction weight weighing
Blanking height is minimum, causes to weigh in the process not fugitive dust.Also dust pollution is just not present.It is existing to reduce dust caused by powder etc.
As.
2, Weight detecting device, since sack is constantly in the state of decline, arrives in weighing sack when the weight of powder
When stopping up to Bottom Of Descent, the load on Weight detecting device can do the convergent oscillation of vertical direction.Resulting additional force
It is added on Weight detecting device together with the weight of material, leads to weighing-up wave serious distortion.In the present invention, pass through
Discharge port lower section be arranged buffer unit, when sack during the decline, one of opening-closing sheet close when, buffer unit
Balance out the impact force of sack, at this point, Weight detecting device can to sack carry out weight detecting, and according to detection as a result,
It can control another opening-closing sheet to be closed step by step, to accurately control the weight of powder in sack.The utility model is especially
It is suitble to carry out metal powder the quantitative weighing of without dust pollution.
3, the opening-closing sheet of the utility model passes through connecting rod and the second vertical actuator control opening and closing, the second vertical actuator tool
There is the function of vertically driving, one end of opening-closing sheet is rotatably arranged on the end of discharge port, and one end of connecting rod is hinged on opening-closing sheet
Medium position, the other end of connecting rod are connected with the second vertical actuator transmission.It is easy to control, it is easy to operate, it is wear-resistant.Preferably
Scheme is that the output end of connecting rod and the second vertical actuator is to be rotatedly connected.Second actuator, connecting rod, opening-closing sheet and funnel it
Between form a four-bar mechanism because the motion profile of the tie point of connecting rod and opening-closing sheet is not vertical straight line, and
It is a camber line centered on opening-closing sheet end, by the setting of the four-bar mechanism, opening-closing sheet opening-closing process can be improved
Middle flexibility ratio is reduced and is rigidly rubbed between part, improves service life.
4, it is additionally provided with exhaust outlet at the top of the funnel of the utility model, by the setting of exhaust outlet, makes powder in pack
The phenomenon in cavity will not be generated, in the process convenient for improving the accuracy that constant volume of the powder in early period packs.
5, the vertically movable mechanism of the utility model includes the vertical actuator of third, sprocket wheel, transmission chain, vertical by third
Actuator band movable sprocket is vertically movable, and transmission chain is made to pull sliding frame mobile, stable transmission, convenient for adjusting.For weighing
The powder of different set weight, when the constant volume of early period weighs, the height of sliding frame decline is different, Ke Yitong certainly
It overregulates the length of transmission chain and adjusts the descending stroke of sliding frame, from can accurately control powder in constant volume early period
It weighs.
