Description
Technical field
This utility model relates to painting field of tool, particularly relates to a kind of electrostatic powder coating powder feeder unit.
Background technology
Electrostatic powder coating be utilize high-pressure electrostatic electric field make electronegative paint particles along the contrary direction directed movement of electric field, and by paint particles absorption at a kind of spraying method of surface of the work.Generally electrostatic power spraying apparatus generally includes spray gun, and spray gun is in order to spray the air-flow of the coating powder with electrostatic.
The powdery paints generally sprayed from spray gun is supplied by powder feeder unit, and the quality of application product is had a great impact by the change of quantity delivered, therefore to ensure application outward appearance and the performance of application product, it is necessary to accurately control powder feeder unit supplies powder amount.Conventional fluidized bed type powder feeder unit, mainly include fluid bed and the ejector filling powdery paints, coating powder is blown by compressed air in fluid bed and fluidizes, fluidisation coating is sucked by ejector, powdery paints is transported to spray gun, owing to lacking volume control device, it is impossible to accurately control the flow of ejector conveying.
Utility model content
This utility model is intended to provide a kind of electrostatic powder coating powder feeder unit, when the spraying using spray gun to carry out electrostatic powder coating, accurately to control the quantity delivered of powdery paints.
Electrostatic powder coating powder feeder unit in this programme, including fluid bed and ejector, fluid bed is provided with the conveying pipe for carrying fluidisation coating, also includes carrier, carrier includes screw rod, transport tube, screw rod is rotatably connected in transport tube, and screw diameter coordinates with transport tube inner wall sealing, and screw rod one end connects buncher, charging hole is had on transport tube sidewall, charging hole connects with conveying pipe, and transport tube one end is communicated with conduit, conduit connection ejector.
The know-why of this programme and when having the beneficial effect that for powder, the fluidisation coating produced in fluid bed is in fluid bed under the blowing of compressed gas, imported in the transport tube of carrier by conveying pipe, start buncher, buncher drives screw rod to rotate, screw rod promotes the fluidisation coating in transport tube to enter in conduit, is imported in ejector by fluidisation coating by conduit；During this, the control of fluidisation coating flow is adjusted by carrier, screw speed is the biggest, the flow of carrier conveying is the biggest, and contrary screw speed is the least, and the flow of carrier conveying is the least, the rotating speed of screw rod is by buncher control, buncher is the motor utilizing methods such as changing the progression of motor, voltage, electric current, frequency to change rotating speed, and buncher can accurately control the rotating speed of screw rod, and then accurately control the quantity delivered of fluidisation coating.
Prioritization scheme one based on such scheme: be provided with valve on described conveying pipe.By Valve controlling whether for powder.
Prioritization scheme two based on prioritization scheme one: being fixed with support on described carrier, support is fixed on described fluid bed.
Prioritization scheme three based on prioritization scheme two: described buncher is fixed on described support.
Prioritization scheme four based on prioritization scheme three: described conveying pipe is fixed on described fluid bed top.Owing to the compressed air of fluid bed is generally passed through from fluidized-bed bottom, conveying pipe is fixed on fluid bed top and is conducive to being formed convection current in fluid bed, it is ensured that powdery paints fluidizes in fluid bed more fully.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment electrostatic powder coating powder feeder unit.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: fluid bed 1, ejector 2, conveying pipe 3, valve 4, support 5, transport tube 6, screw rod 7, buncher 8, charging hole 9, conduit 10.
Embodiment electrostatic powder coating powder feeder unit is the most as shown in Figure 1: include fluid bed 1 and ejector 2, fluid bed 1 top is fixed with conveying pipe 3, conveying pipe 3 connects fluid bed 1, on conveying pipe 3, valve 4 is installed, also include carrier, support 5 it is fixed with on carrier, support 5 is fixed on fluid bed 1, carrier includes screw rod 7, transport tube 6, screw rod 7 is rotatably connected in transport tube 6, screw rod 7 diameter coordinates with transport tube 6 inner wall sealing, screw rod 7 one end connects buncher 8, buncher 8 is fixed on support 5, charging hole 9 is had on transport tube 6 sidewall, charging hole 9 connects with conveying pipe 3, transport tube 6 one end is communicated with conduit 10, conduit 10 connects ejector 2.
During for powder, open valve 4, the fluidisation coating produced in fluid bed 1 imports in the transport tube 6 of carrier by conveying pipe 3, start buncher 8, buncher 8 drives screw rod 7 to rotate, screw rod 7 promotes the fluidisation coating in transport tube 6 to enter in conduit 10, is imported in ejector 2 by fluidisation coating by conduit 10；During this, the control of fluidisation coating flow is adjusted by carrier, screw rod 7 rotating speed is the biggest, the flow of carrier conveying is the biggest, contrary screw rod 7 rotating speed is the least, and the flow of carrier conveying is the least, and the rotating speed of screw rod 7 is controlled by buncher 8, buncher 8 can accurately control the rotating speed of screw rod 7, and then accurately controls the quantity delivered of fluidisation coating.
When needing to stop for powder, the rotation closing valve 4 or stopping buncher 8 can stop for powder.
Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic too much describes at this.Should be understood that; for a person skilled in the art, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
