Description
Technical field
The utility model relates to a kind of negative pressure automatic proportioning feeding device, particularly relates to the automatic proportioning feeding device of the large-scale melt extruder of Polymer, belongs to machinery and automation engineering technical field.
Background technology
Be matched in cast film line Bulk plastic extruder, because follow-up auxiliary facility has certain height, extruder just can meet the requirement of production technology process after needing erection to leave the certain height in ground, add the height of extruder self, its feeder hopper leaves the distance that ground just has several meters, owing to being large-scale plant, the demand of plastic raw materials is just larger, if employing its work capacity of hand fed and labour intensity all can be very large, add that the raw material of use is multiple compound type, hand fed is also easily made mistakes.Traditional feeding manner is the platform set up by spice facility higher than hopper, then by pipeline, the raw material mixed is adopted the mode feed hopper feeding of automatic control flow, the defect of this mode is a large amount of raw materials to be hung and is raised to after high platform spice again, not only need the construction of input spice storing platform, consume a large amount of lifting energy, also there is many inconvenience compared to ground spice.
Summary of the invention
For solving above-mentioned technological deficiency, the utility model provides a kind of negative pressure automatic proportioning feeding device, and object is to facilitate the operation of spice program, reduces platform construction investment, reduces energy resource consumption.
The technical scheme that the utility model adopts is: a kind of negative pressure automatic proportioning feeding device, is made up of controller, conveying unit, negative pressure air unit, and controller is take PLC as the control system and the interface that comprise more than at least two of core; Conveying unit comprises feed bin, suction tube way, connecting portion, charging line, feed bin is positioned in the ground of raw material silo, and one end of suction pipeline extends to the bottom of feed bin, and the other end extends to connecting portion, one end of charging line is connected to connecting portion, and the other end extends to hopper; Negative pressure air unit comprises negative-pressure air fan, negative pressure tracheae, and negative pressure tracheae is connected between connecting portion and negative-pressure air fan, and conveying unit and negative pressure air unit are supporting setting, comprises more than at least two covers, and the independence accepting control system respectively controls.
Controller is according to the formula that feeds intake pre-entered, control the running velocity of negative pressure air unit, time of run and operation interval respectively, negative pressure air unit manufactures negative pressure air at connecting portion, suction tube way draws raw material by feed bin under the effect of negative pressure air, and raw material is transported to the hopper of extruder through connecting portion, charging line.
The beneficial effects of the utility model are: adopting with PLC is the control system comprising more than at least two of core, automatically according to the formula batching of input, exempt spice program; By negative pressure air unit making negative pressure air, raw material is inhaled to deliver to by the low side being in warehouse floor is in high-end hopper, saves a large amount of raw materials and hangs transport and the configuration sending the energy, proportioning platform construction fund and facilitate raw material.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Fig. 1 is construction profile schematic diagram of the present utility model.
In figure 1, extruder, 2, hopper, 3, charging line, 4, connecting portion, 5, negative pressure tracheae, 6, suction pipeline, 7, feed bin, 8, negative-pressure air fan, 9, controller.
Detailed description of the invention
In the embodiment in figure 1, a kind of negative pressure automatic proportioning feeding device, is made up of controller 9, conveying unit, negative pressure air unit, and controller 9 is take PLC as the control system and the interface that comprise more than at least two of core; Conveying unit comprises feed bin 7, suction tube way 6, connecting portion 4, charging line 3, feed bin 7 is positioned in the ground of raw material silo, one end of suction pipeline 6 extends to the bottom of feed bin 7, the other end extends to connecting portion 4, one end of charging line 3 is connected to connecting portion 4, and the other end extends to hopper 2; Negative pressure air unit comprises negative-pressure air fan 8, negative pressure tracheae 5, and negative pressure tracheae 5 is connected between connecting portion 4 and negative-pressure air fan 8.
Embodiment: according to the recipe requirements manufactured a product, composition of raw materials is pre-entered at controller 9, controller 9 is according to the formula that feeds intake pre-entered, the raw material of PLC to formula ratio is converted into the running velocity of negative-pressure air fan 8, time of run and operation interval, negative-pressure air fan 8 manufactures negative pressure air by negative pressure tracheae 5 at connecting portion 4, suction pipeline 6 draws raw material by feed bin 7 under the effect of negative pressure air, and raw material is transported to the hopper 2 of extruder 1 through connecting portion 4, charging line 3.
