A pulse plug flow pneumatic transmission device on the injection molding machine comprises a hopper, compressed air, a conveying tank, a feed delivery pipe, an air knife, a material inlet box body of the injection molding machine and a pulse dust collector, and is characterized in that the whole transmission process is sealed, plastic raw materials are in alternative states of material plug to gas plug to material plug in a pipeline under the action of pulse air flow cutting. Pressure differences are formed at the two ends of the material plug, the materials are pushed to move forward under the action of static pressure, and compared with a pneumatic vacuum feeding machine, the pulse plug flow pneumatic transmission device saves electricity and is also characterized in that the pulse dust collector has high dust-gas ratio, and the tail gas discharging amount conforms to the discharge standard. Compared with the prior art, the pulse plug flow pneumatic transmission device on the injection molding machine has the effects of green, environmental protection, capability of not polluting air, low noise, high degree of automation and energy conservation.
Description
Technical field
The present invention relates to the injection machine technical field, relate in particular to a kind of feeding device of injection machine.
Background technology
The feeding device of existing injection machine, its structure is loose open, and using of having is artificial, and the quantity of using mechanical transfer, particularly large size plastic jetting-moulding device to feed in raw material that has is very big, if whole process just seems that by manual operation efficient is low; If use mechanical transfer, be open, structure is disperseed, volume is big, pollutes the air of production environment, and the person is also dangerous; If adopt the strength suction to move or blow, noise is big, and power consumption is many, and system and equipment are numerous and diverse, has produced installation and has keeped in repair inconvenient.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of prior art, be provided for injection machine, the injection machine feeding device of compact conformation, sealing, environmental protection, energy-conservation and high efficiency.
The technical scheme that the present invention taked is: the pulse plug flow Pneumatic conveyer comprises hopper, pressurized air, conveying pot, conveying pipeline, air knife, injection machine inlet point casing and pulse dust collector composition on the injection machine.Described hopper is used for that the feeding of preparing plastic raw material uses, and the general the same height with terrace of feed hopper bottom openning is connected to conveying pot, conveying pipeline; The air compressor delivery piping that described pressurized air is had by factory, described air knife is a kind of gas valve, valve is by solenoid control; Electromagnetic valve is controlled by pulse signal generator, and gas valve is supplied gas do pulse by required opening and closing time, and described injection machine inlet point casing comprises material storing box and is connected pedestal; Connect pedestal and be fixed on injection machine inlet point place; A pair of infrared is housed in the described material storing box receives head, whether case is full for raw material in the monitoring material storing box, in time sends signal; The control pressurized air is sent and is not bothered to see me out, and described pulse dust collector is made up of pipeline and dust-collector.Its working process is: plastic raw materials gets into conveying pot by hopper, and (a jar internal pressure is about 60～180kPa), under the pressurized air effect, gets into conveying pipeline, and (air knife pressure is about 80～200kPa) and gets into pipeline air pulse through air knife; Like this, plastic raw materials promptly is separated into discontinuous efflux of solids (plug flow) by air knife and is transferred, and the length of material plunger can be controlled by the air pulse of air knife; Air knife is bubbling air in conveying pipeline discontinuously; The cutting stock column makes it to become discontinuous plug flow (i.e. one section stock column plug, one section gas column plug); Plastic raw materials leans on gas-static to promote to be transported to injection machine inlet point casing; It is characterized in that: whole transportation process is a leak free, and plastic raw materials presents the state that material bolt-aeroembolism-the material bolt replaces in the pipeline under the effect of air pulse cutting.Form pressure reduction at material bolt two ends, under the effect of static pressure, promote material and advance, than Pneumatic Vacuum Appending Machine saves energy, its characteristic is that also pulse dust collector has the characteristics of high grey gas ratio, tail gas allow compliance with emission standards.
The present invention compared with prior art, its effect is environmental protection, foul air not, noise is low, degree of automation is high, and is energy-conservation.Because common gas delivery mode is to rely on the dynamic pressure of delivering gas to carry conveying; It then is that the differential static pressure of aeroembolism is passed conveying that bolt stream is carried what utilize; And the activity of material is a bolt shape stream, so the delivery speed that bolt stream is carried can reduce greatly, and noise is low; Air consumption also decreases a lot, just produces compressed-air actuated power consumption and can reduce a lot.In addition, bolt stream carries the ash disposal system that constitutes also to have the characteristics of low energy consumption, high grey gas ratio, and this makes that the vent gas treatment amount of carrying is few, tail gas treatment device is simplified, and can be guaranteed the tail gas allow compliance with emission standards.
