Description
Technical field
The present invention relates to a kind of industrial coater nozzle, particularly relate to a kind of atomizer removing nozzle kiss-coating.
Background technology
In some industrial processes, it is often necessary to use high accuracy paint-on technique, such as: the fluorescent powder coating technique in white light emitting diode (white light LEDs) encapsulation process.So-called high accuracy paint-on technique, mainly requires that coated weight each time only allows to there is minimum error during extensive repeatedly coating.So-called kiss-coating, it is simply that when coating high viscosity liquid, owing to liquid viscosity is relatively big, after spraying every time, will necessarily remain a certain amount of viscous liquid in coater nozzle, if removed not in time, will necessarily under the influence of liquid coated weight once.So the kiss-coating phenomenon eliminating nozzle is the critical process link in high accuracy paint-on technique.
Summary of the invention
It is an object of the invention to provide a kind of atomizer removing nozzle kiss-coating, the problem affecting coating precision when can solve accurately to coat high-concentration colloid owing to kiss-coating occurs in atomizer nozzle.
The present invention solves the scheme that its technical problem taked:
A kind of atomizer removing nozzle kiss-coating, it includes colloid passage, atomization gas passage and removing glue passage, colloid passage is installed on the centre of atomizer, and atomization gas passage is installed on the periphery of colloid passage, and removing glue passage is installed on the periphery of atomization gas passage；Atomization gas passage, the coating colloid flowed out from colloid passage for atomization, atomization gas channel outlet is towards the central shaft of colloid passage, and atomization gas, around colloid passway and from the colloid collision that colloid passage flows out, produces atomizing effect；Described removing glue passage, hangs over colloid unnecessary on nozzle after absorbing coating every time；The suction Jiao Kou of removing glue passage is towards the central shaft of colloid passage；The suction inlet of removing glue passage is tubaeform, bore at suction inlet is more than the removing glue channel internal diameter of nozzle interior, removing glue passage is longer than the removing glue passage inwall near nozzle center away from the inwall of nozzle center, and removing glue passage is connected with vacuum generator, produces suction effect.
Above-mentioned colloid passage is positioned at the centre of atomizer, and colloid passage is column type or rounding bench-type passage.
Above-mentioned colloid channel cross-section is circular, and the cross section of atomization gas passage is annular, and the cross section of removing glue passage is circular.
Compared with prior art, there is advantages that
Present configuration is simple, but smart structural design, shape design between each passage and the design of structural relation, can remove rapidly the colloid remained in around various atomizer, the problem affecting coating precision owing to kiss-coating occurs in atomizer nozzle when solving accurate coating colloid.
Accompanying drawing explanation
Fig. 1 is the atomizer cross section structure schematic diagram that the present invention can remove nozzle kiss-coating.
Fig. 2 is that the present invention can remove the atomizer of nozzle kiss-coating and looks down structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the enforcement of the present invention is described further, but the enforcement of the present invention and protection domain are not limited to this.
As shown in Figure 1, a kind of atomizer removing nozzle kiss-coating, the problem affecting coating precision during for solving accurately to coat colloid owing to kiss-coating occurs in atomizer nozzle, structure includes colloid passage 1, atomization gas passage 2, removing glue passage 3, wherein circular colloid passage 1 is installed on the centre of atomizer, the atomization gas passage 2 of toroidal is installed on the periphery of colloid passage 1, and the removing glue passage 3 of toroidal is installed on the periphery of atomization gas passage 2.
Colloid passage 1, at the uniform velocity flowing out the colloid of coating, is arranged on Centromedian column type or the inverted cone bench-type passage of atomizer, depending on channel diameter requires according to different coated weights.
Atomization gas passage 2, the colloid of coating is at the uniform velocity flowed out for atomization, the coating colloid flowed out from colloid passage 1 for atomization, the atomization gas passage 2 of toroidal is installed on the periphery of colloid passage 1, atomization gas passage 2 exports the central shaft towards colloid passage 1, be conducive to atomization gas to collide with the colloid flowed out from colloid passage 1 around 2 mouthfuls of colloid passage, produce atomizing effect.
Removing glue passage 3, hangs over colloid unnecessary on nozzle after absorbing coating every time, and the removing glue passage 3 of toroidal is installed on the periphery of atomization gas passage 2, and the suction Jiao Kou of removing glue passage 3 is towards the central shaft of colloid passage 1；At removing glue passage 3 suction inlet, suction inlet journey is tubaeform, and the passage at suction inlet is wider than the removing glue passage 3 of nozzle interior, and removing glue passage 3 is longer than the inwall near nozzle center away from the inwall of nozzle center.When there is kiss-coating on coating rear nozzle every time, controlling the work of small size vacuum generator, removing glue passage 3 produces suction, siphons away the colloid remaining on nozzle.Also make the kiss-coating can be close to the removing glue passage horn mouth of peripheral attachments or mobile towards the atomization gas channel outlet of central shaft, it is due to removing glue channel internal diameter bigger inwall length at the nozzle inwall less more than internal diameter more cleverly, this structure acts synergistically in horn mouth, kiss-coating can be made to be easier to be sucked away, atomization gas channel outlet is towards designing also together with this structure, portion gas is made to be turned back by the inwall that removing glue channel internal diameter is bigger, atomizing effect more preferably and is conducive to vibrating kiss-coating, improves the removing glue effect of removing glue passage further.
As in figure 2 it is shown, be that the atomizer that can remove nozzle kiss-coating looks down structural representation.Including colloid passage 1, atomization gas passage 2, removing glue passage 3.
As above the technique effect described in the present invention acquirement can preferably be realized, after spraying every time, the small size vacuum generator connecting removing glue passage begins to work, produces suction, siphoned away hanging over high-concentration colloid unnecessary on nozzle by removing glue passage, thus realize the function of removing glue.
