Detailed description of the invention
Below embodiment of the present utility model is described in detail:
As shown in Figure 1-2, be a kind of powder spray coating head, comprise nozzle body 1 and coating hood 2, one end of nozzle body 1 is the spout for powder spray, and coating hood 2 is arranged on nozzle, is provided with suction channel 18 in nozzle body 1, suction channel 18 and spout connection.Wherein, spout carries out spraying operation for spraying powder; Coating hood 2 is for covering target area workpiece (namely needing the object carrying out spraying) needing spray, the coverage of powder is made to be limited in target area, the cover mouth of coating hood 2 and the surface of target area suitable, can be different because the surface of target area is different; The recovery of powdery paints unnecessary when suction channel 18 is for completing spraying operation.
In the present embodiment, diffusion chamber 11 is provided with in spout, powder out carries out spraying operation from diffusion chamber 11, coating hood 2 comprises outer cover 21 and inner cover 22, inner cover 22 is arranged in the chamber of outer cover 21, outer cover 21 is suitable and formed with the outer wall of nozzle body 1 and be slidably connected with spout, outer cover 21 is provided with elastic component 14 (as spring) with the place of being slidably connected of the outer wall of nozzle body 1, this elastic component 14 replys slip for making outer cover 21 along the outer wall of nozzle body 1, the outer wall of nozzle body 1 is also provided with positioning retainer ring 15, positioning retainer ring 15 is suitable with elastic component 14, this outer cover 21 needs the target area of spraying (the cover mouth of outer cover 21 can be different because the surface of target area is different) for tentatively limiting, and by flexible type slip, certain extruding force is produced to target area, thus more strictly control spraying area, avoid powder to leak and relate to other regions, inner cover 22 is corresponding with diffusion chamber 11, and inner cover 22 needs the target area of spraying for limiting further, and prevents powder from leaking further.
In the present embodiment, outer cover 21 is provided with multiple first passage 23, the outer wall of nozzle body 1 and the place of being slidably connected of outer cover 21 are provided with multiple second passage 19, and when outer cover 21 slides on the outer wall of nozzle body 1, the first passage 23 can be communicated with the second passage 19, suction channel 18.Which can reclaim unnecessary powdery paints, detailed process comprises two steps: 1, after the spraying completing target area, powdery paints unnecessary in coating hood 2 is drawn back from suction channel 18 by the pumping equipment of peripheral hardware, now the inside of coating hood 2 is by the second passage 19, first passage 23 and and ft connection, the backflow direction of air-flow is: outside → first passage 23 → the second passage 19 → suction channel 18, which can suck back the powdery paints of floating state well, and the powdery paints be sticky on target area can not be sucked back, therefore play the effect of reclaiming excess powder paint, 2, when this powder spray coating head leaves that time of target area, outer cover 21 rebounds under the effect of elastic component 14, now just the second passage 19 in shutoff, because of the effect of air, the flow direction of air-flow is: outside → first passage 23 → coating hood 2 → spout → suction channel 18, which can reclaim the powdery paints of floating state further, thus prevents them from leaking.Wherein, inner cover 22 is rubber cover or PU cover, or other flexible material covers, because having good elasticity and toughness, can form an airtight good space, preventing powder from leaking when pressing to workpiece.
In the present embodiment, be also provided with and press swivel nut 12 in spout, it is suitable with diffusion chamber 11 to press swivel nut 12, and press on swivel nut 12 and be also provided with powder blocking plate 13, this powder blocking plate 13 faces the central area of diffusion chamber 11, and inner cover 22 is positioned at this and presses swivel nut 12 periphery place.Powder blocking plate 13 is not for needing the part sprayed in shelter target region, its large I is determined according to situation.Press swivel nut 12 for fixing powder blocking plate 13, make powder blocking plate 13 can face the central area of diffusion chamber 11.
In the present embodiment, nozzle body 1 comprises electric discharge device 16, and electric discharge device 16 is positioned at diffusion chamber 11, for the surface making powder belt Electro Sorb need the target area sprayed on workpiece.Nozzle body 1 also comprises air supply pipe 17, and air supply pipe 17 is communicated with electric discharge device 16, for supplying powder and air pressure.
Above-mentioned powder spray coating head is when implementing spraying to target area workpiece needing spray, the outer cover 21 of coating hood 2 covers target area, and slide backward along the outer wall of nozzle body 1, effect because of elastic component 14 makes outer cover 21 can cover target area tightly, in this process, inner cover 22 is also compressed, make the space that in target area, formation one is airtight, powder is supplied by air supply pipe 17, powder is charged when electric discharge device 16, spray from diffusion chamber 11, then be adsorbed in target area, spray complete just stopping for powder, unnecessary powder by by the pumping equipment of peripheral hardware or normal barometric pressure from the suction channel 18 of nozzle body 1 reclaim (namely above-mentioned mention 1, 2 two-step methods).In the process of spraying, powder can only cover target area, can not leak, therefore can carry out good spraying operation to workpiece needing the target area sprayed.This process is carried out repeatedly, just can realize continuous seepage operation.Dried by relevant drying plant more afterwards, just can make workpiece to need the target area sprayed obtain the protection of good anti-acidifying corruption.This powder spray coating head had both made spraying operation efficiently high-quality, saved again coating and reduced pollution, thus was beneficial to staff's health and environment.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
