One is weighed blanking device
The present invention relates to blanking technical field of weighing, be specifically related to one and weigh blanking device.
The main metering method of present package packing machine has spiral to measure, electronic scale metering etc.Conveyor screw is a kind of common device for transporting objects, and normally comprise feed pipe and be positioned at the rotating shaft of feed pipe, be distributed with helicallobe around this rotating shaft, rotating shaft can be in transmission connection by the transmission devices such as belt, gear or chain and drive motor.In macromolecule material product industry, utilize the continuous rotation of helicallobe to push the conveying machinery of material, mainly for delivery of powdery, particulate bulk materials such as carbon black, calcium carbonate, stearic acid, zinc oxide, dulphur flowers.Existing blanking device of weighing all is designed with three motors, transmission stirring device, little conveyor screw, large conveyor screw respectively, vertically arrange successively from top to bottom, mixing device, little conveyor screw, large conveyor screw two ends are all fixed in bearing mode, and helicallobe shape is identical, be uniformly distributed.Although this kind of apparatus design can realize predetermined function, meet and use, the volume of its whole device is relatively large, manufacturing cost also higher, power consumption is also larger, and be unfavorable for coordinating metering outfit to improve measuring accuracy; And this device computation weigh speed is slow.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of measuring accuracy high and metered rate is fast one is weighed blanking device.
For solving the problems of the technologies described above, one of the present invention is weighed blanking device, comprise bracing frame and gauging device, described gauging device is connected with bracing frame by LOAD CELLS, described gauging device comprises the weighing bucket be connected with LOAD CELLS and the collection bucket be located at below weighing bucket, and the discharging opening of described collection bucket is provided with the switching mechanism for controlling this discharging opening folding.
The discharge gate of described weighing bucket is provided with the switching mechanism for controlling this discharge gate folding.
Described switching mechanism comprises is located at the cylinder on weighing bucket or collection bucket sidewall, the bin gate for closed discharging opening or discharge gate, and is connected with this bin gate and is driven by cylinder it to open or close the turnover panel of bin gate; Weighing bucket immediately below cylinder or the sidewall of collection bucket are installed with a base, one end of described turnover panel is fixedly connected with bin gate, the other end of turnover panel and being connected with base rotation by rotating shaft near the inner side of weighing bucket or collection bucket sidewall, be flexibly connected with the piston rod of cylinder by dwang outside it, drive turnover panel to rotate by the motion of cylinder piston rod, and then drive opening or closing of bin gate.
Described LOAD CELLS is fixedly connected with bracing frame by sensor installation seat.
Described weighing bucket and collection bucket sidewall are equipped with dust excluding hood.
The inlet point that described discharge gate stretches into collection bucket is inner.
The invention has the beneficial effects as follows: one of the present invention is weighed blanking device, the mode adopting weighing bucket and collection bucket to combine is weighed to material and carries, and do not take time waits, improves and measures and package speed; Adopt LOAD CELLS to measure material, improve measuring accuracy.The weighing bucket of this blanking device and collection bucket are equipped with dust excluding hood, avoid dust and expose contaminated environment.Be equipped with switching mechanism at the discharging opening of collection bucket and the discharge gate of weighing bucket, controlled the folding of material mouth by switching mechanism, thus well control the turnover of material, avoid the accumulation of material or the not anxious situation of the too fast collection caused of discharge of materials to occur.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, one is weighed blanking device, comprise bracing frame 1 and gauging device 2, gauging device 2 is connected with bracing frame 1 by LOAD CELLS 3, gauging device 2 comprises the weighing bucket 31 be connected with LOAD CELLS 3 and the collection bucket 32 be located at below weighing bucket 31, and the discharging opening of collection bucket 32 and the discharge gate of weighing bucket 31 are equipped with the switching mechanism 4 for controlling this discharging opening or discharge gate folding.
Switching mechanism 4 comprises is located at the cylinder 41 on weighing bucket 31 or collection bucket 32 sidewall, the bin gate 42 for closed discharging opening or discharge gate, and is connected with this bin gate 42 and the turnover panel 43 driving it to open or close bin gate 42 by cylinder 41; Weighing bucket 31 immediately below cylinder 41 or the sidewall of collection bucket 32 are installed with a base 5, one end of turnover panel 43 is fixedly connected with bin gate 42, the other end of turnover panel 43 and being rotationally connected by rotating shaft and base 5 near the inner side of weighing bucket 31 or collection bucket 32 sidewall, be flexibly connected with the piston rod of cylinder 41 by dwang 6 outside it, drive turnover panel 43 to rotate by the motion of cylinder piston rod, the rotation of turnover panel 43 drives opening of bin gate 42 or closed.
Further, LOAD CELLS 3 is fixedly connected with bracing frame 1 by sensor installation seat 7.
Further, weighing bucket 31 and collection bucket 32 sidewall are equipped with dust excluding hood 8, avoid dust and expose contaminated environment.
Further, the inlet point that discharge gate stretches into collection bucket 32 is inner, improves weighing bucket 31 and being connected during collection bucket 32 discharge of materials, avoids dust to expose.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
