Description

Negative friction static plastic spraying machine

The utility model is to utilize driven by motor impeller rotation, produces negative pressure, plastic powders is sucked and with friction generation static such as blade after be sprayed on a kind of device of metal surface, belong to the electrostatic plastic spraying field.

Utilize electrostatic plastic spraying, be replace that tradition is sprayed paint, a kind of advanced technology of mopping, japanning.At present; electrostatic plastic spraying mainly contains two kinds of modes; a kind of is the high-pressure electrostatic plastic-blasting; its groundwork process is that the high pressure draught that produces with air compressor is through water-oil separating; after decompressions etc. are handled; act on the powder in the powder feeder and form high-pressure powder stream; again from the muzzle ejection of dusting; when ejection; the electrostatic field corona of the 50-120KV high direct voltage that produces by high pressure generator; form charged powder stream and sprayed to the metal works of ground connection and be attracted to surface of the work, can form plastic protective layer through the drying that is heating and curing then.Another kind is the low pressure electrostatic plastic spraying; its course of work and high-pressure electrostatic plastic-blasting are similar; also need to produce high pressure draught with air compressor; after water-oil separating and decompression etc. are handled; act on the powder in the powder feeder and form high-pressure powder stream; difference only produces electrostatic field at the spout place without high pressure generator; and spray gun is made concavo-convex slot type structure; make powder under the pressure of high pressure draught; produce static with the lance body structure friction; spray to the workpiece of ground connection then with air-flow, and be attracted to surface of the work, form plastic protective layer through being heating and curing drying again.In sum, existing plastics spraying machine exists required pressure vessel more, the equipment complexity, and plastic-blasting THICKNESS CONTROL difficulty also will have the high voltage electric field of 50-120KV for the high-pressure electrostatic plastics spraying machine, makes operation increase shortcomings such as difficulty.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, provides a kind of simple in structure, easy-to-operate, and plastic-blasting thickness is the enclosed negative pressure friction-type electrostatic plastic spraying machine of control easily.

Once finish in the container that the utility model will be for powder, reclaim powder, soak powder, operation such as dust concentrates on a sealing, high voltage installations such as air compressor, oil water separator, pressure reducer, powder feeder equal pressure container and high pressure generator have been cancelled, the main frame cost is reduced greatly, both had the plastic-blasting function, have again to soak and mould function, realize closed integrated operation, improved the quality of plastic-blasting product, improved working condition.The closed box that the utility model mainly is made up of the circular hole of tubular cabinet, chassis lid, base, observation window, powder input port, machine box door and installation rubber operation gloves, by two conically shapeds up and down with at top cylinder the sandwich-type collection powder tube that some valve are formed is housed, the powder immersing device that motor is formed is moulded in soaking below electric motor with vane wheel in collection powder collet chuck layer, valve, the interlayer and interlayer, form by duster and workpiece clamp, variable-frequency power and cable that suction powder flexible pipe, support flexible pipe, plastic-blasting motor, electric motor with vane wheel and impeller chimney are formed.Wherein, workpiece clamp is contained on the chassis lid, and the workpiece clamp bottom puts in the cabinet, is used for folder and hangs workpiece, and there is a rotating disk on workpiece clamp top and is connected with ground with lead; Collection powder wound packages is in the cabinet bottom, nozzle upwards and with the cabinet inwall is connected, and a powder input port with cover is arranged on the cabinet wall above the nozzle, and top cylinder is contained in the doffing, the top cylinder nozzle is connected with the doffing middle part, top cylinder edge in the junction is equipped with the tube limit valve that several upwardly open, in top cylinder bottom centre, a tube end valve of opening downwards is housed, above the tube end valve packing ring is arranged, around the packing ring some suction powder flexible pipes are housed, on packing ring, paste a guard; Soak and mould the below that motor is contained in collection powder tube, motor shaft puts in by sealing ring in the interlayer of collection powder tube, with place tin at the bottom of the electric motor with vane wheel of valve below fixedly connected; Duster is supported on cabinet top by supporting flexible pipe, the motor that dusts is contained in the outside of cydariform impeller chimney, its motor shaft puts in the impeller chimney by sealing ring fixedlys connected with electric motor with vane wheel, the opposite side center of impeller chimney, be connected on a powder inlet being arranged and inhaling the powder flexible pipe, one nozzle arranged at the impeller chimney edge; The output that is installed in the variable-frequency governor of cabinet bottom is moulded motor and is connected with the plastic-blasting motor with soaking respectively with cable, and the fm dial of variable-frequency governor is installed on the cabinet wall, and the power line of variable-frequency governor passes the cabinet wall and is electrically connected with the city; In the cabinet all can with the plastic powders parts in contact, except that workpiece and workpiece clamp, be insulating materials and make, or use wrapped with insulation, electric motor with vane wheel is made with glass or pottery, fluoroplastics, nylon, leather, the contour insulating materials of silk.During work, mould the electric motor with vane wheel center and produce negative pressure soaking, with be contained in powder valve at the bottom of the tube in the collection powder tube suck interlayer with wheel rotation after, around upwards spraying to workpiece along interlayer from tube limit valve, simultaneously, electric motor with vane wheel center at duster also produces negative pressure, by inhaling the powder that the powder flexible pipe sucks from collection powder tube bottom, with wheel rotation after nozzle sprays to workpiece, by rubber operation gloves, can put in order the position of duster with hand adjustment, since powder at the volley with electric motor with vane wheel, insulating materials friction such as impeller chimney and collection powder collet chuck layer and produced static, these charged powders are adsorbed on surface of the work with the grounded metal workpiece because of having suction when flying to workpiece, some static content is little and fail to be adsorbed on the powder of surface of the work, falling into collection powder tube can reuse, the output frequency of adjustment variable-frequency governor can be adjusted motor speed very easily, thereby changes movement velocity and powder belt electric weight, thereby has realized the purpose of control plastic-blasting thickness.

The utlity model has simple in structure, cost only is the 10-20% of like product, and easy-to-operate is moulded electrostatic plastic spraying and soaking, all concentrate in the same closed container for Powder Recovery etc., reduce operation sequence, reduce dust and invade, prevent to pollute, help improving the quality of plastic-blasting product, plastic-blasting thickness is controlled easily, advantages such as no sag phenomenon can satisfy the requirement of different workpieces to plastic-blasting, are a kind of desirable electrostatic plastic spraying machines.
