Also combination is referring to Fig. 3 referring to Fig. 1, Fig. 2, and spraying machine of the present utility model comprises recovery cover 10, bearing 20, sheath body 30 and housing 50.
Reclaim the both sides, bottom of cover 10 and extend a frame plate 12 downwards, frame plate 12 is provided with a plurality of grooves 13, and the top of reclaiming cover 10 is provided with spout 14.
The bottom of bearing 20 is provided with nozzle 11, and as shown in Figure 2, nozzle 11 is connected by pipeline and pressure mechanism 40, bearing inside is provided with the bearing guiding face 21 of inclination, reclaim cover 10 for bearing, this bearing 20 and 10 on recovery cover are formed with the gap, and the not end of bearing guiding face 21 is provided with return duct 22.
The end face of housing 50 is provided with breach 51 and an accumulator tank 52 relative with nozzle 11, as shown in Figure 3, its end face also is provided with recovery holes 54, be provided with gas port 53 in the side of housing 50, be used to adsorb the scaling powder that is vaporific, preventing that scaling powder from outwards flying away pollutes, and the bottom of accumulator tank 52 then is communicated with bearing 20 by pipeline.
Referring to Fig. 4, shown pressure mechanism 40 includes flux bath 41, pump 42 and storage and presses chamber 43.Scaling powder is installed in the flux bath 41, and under the cooperation of pipeline, the scaling powder after pump 42 will be exerted pressure is delivered to storage and presses in the chamber 43, when treating that storage presses chamber 43 internal pressures excessive, will be back to flux bath 41 by the scaling powder that pump 42 is carried by relief valve 47.Another pipeline of this storage pressure chamber 43 is delivered to nozzle 11 with the scaling powder of high pressure conditions, and makes nozzle 11 that scaling powder is vaporific outside injection.Pressing chamber 43 and 11 at nozzle to have an air to take over 44 in addition in storage stretches out, guide the clean gas of high pressure and it is delivered to nozzle 11, air is taken over 44 and is subjected to electromagnetically operated valve 45 conductings whether control, and in order to prevent that scaling powder from refluxing, press between the chamber 43 at pump 42 and storage, and nozzle 11, storage are pressed and are equipped with non-return valve 46 between chamber 43, the electromagnetically operated valve 45 and reflux to prevent scaling powder.
Above-mentioned member is after assembling, starting pressure mechanism 40, at scaling powder during from nozzle 11 ejection, flow through through the gap of 20 of sheath body 30 and bearings bearing 20 and reclaim the gap of 10 on cover and enter and reclaim in the cover 10 of outside air, scaling powder evenly and is sprayed with nebulizing, as shown in Figure 3 from spout 14
As shown in Figure 3, this spraying machine is in operating process, and the vaporific scaling powder that sprays outside reclaiming cover 10 from spout 14 is attached to outside the machine plate, and part waste gas can rebound and reclaim filtration through recovery holes 54 and gas port 53.The part scaling powder is deposited in the accumulator tank 52, and reclaims and concentrate on the scaling powder of bearing 20 inside, can be back to flux bath 41 inside via return duct 22, recycles, and can reduce the waste and the outflow of scaling powder and pollute.
Referring to Fig. 5, this spraying machine is independent with pressure mechanism 40, and be placed on control body 60 the bottom, recovery cover 10, bearing 20 are then gone ahead of the rest with sheath body 30 and housing 50 combinations, place again in traditional solder furnace, and the overall volume that can dwindle spraying machine, and can be fit to the solder furnace of various types and specification.
When nozzle 11 is hoarded even during stopped nozzles 11 because of access times too much cause scaling powder, but opens solenoid valve 45, high pressure and clean gas are cleaned nozzle under the state of high pressure high flow rate, can be referring to Fig. 4, not only can make things convenient for and promptly finish cleaning, also can save artificial and consuming time.
In sum, spraying machine of the present utility model, pressure mechanism is independent, and will reclaim cover, bearing, sheath body and shell combination in solder furnace inside, can reduce overall volume, simultaneously pressure mechanism is equipped with the gas of tracheae with the input cleaning in addition, can carry out cleaning to nozzle, and preventing that scaling powder from hoarding in nozzle influences its injection.Have improve welding quality, save artificial, save benefit such as man-hour.
