Embodiment Construction

[0011] The implementation of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection scope of the present invention are not limited thereto.

[0012] Such as figure 1 As shown, an atomizing nozzle that can clear the glue on the nozzle is used to solve the problem that the coating accuracy is affected by the glue on the nozzle of the atomizing nozzle when accurately coating the colloid. The structure includes a colloid channel 1 and an atomizing gas channel 2 , Glue removal channel 3, wherein the circular colloid channel 1 is installed in the center of the atomization nozzle, the ring-shaped atomizing gas channel 2 is installed on the periphery of the colloid channel 1, and the ring-shaped glue removal channel 3 is installed in the The periphery of the atomizing gas channel 2.

[0013] Colloid channel 1 is used to flow out the colloid for coating at a constant speed. It is a cylindrical or inver...

Abstract

The invention relates to an atomizing nozzle capable of cleaning nozzle hung colloid. The atomizing nozzle comprises a colloid channel, an atomizing gas channel and a colloid removing channel; the colloid channel is mounted in the center of the atomizing nozzle; the atomizing gas channel is mounted in the periphery of the colloid channel and used to atomize coating colloid flowing from the colloid channel; the colloid removing channel is mounted in the periphery of the atomizing gas channel and used to absorb to remove excessive colloid hanging on the nozzle after each coating; a colloid absorbing port of the colloid removing channel faces a central shaft of the colloid channel; an absorbing inlet of the colloid removing channel is loudspeaker-shaped; the aperture of the absorbing inlet is more than the inside diameter of the colloid removing channel in the nozzle. With the adoption of the atomizing nozzle capable of cleaning the nozzle hung colloid, the problem that hung-colloid appears at the nozzle of an atomizing spray head during accurately coating high-concentration colloid and influences the coating precision can be solved.

Description

technical field [0001] The invention relates to an industrial coating nozzle, in particular to an atomizing nozzle capable of clearing glue on the nozzle. Background technique [0002] In some industrial production processes, high-precision coating technology is often required, such as the phosphor coating process in the packaging process of white light-emitting diodes (white LEDs). The so-called high-precision coating technology mainly requires that in the process of large-scale multiple coatings, only a very small error is allowed in the amount of coating each time. The so-called hanging glue means that when coating high-viscosity liquid, due to the high viscosity of the liquid, after each spraying, a certain amount of viscous liquid will inevitably remain on the coating nozzle. If it is not removed in time, it will inevitably affect the next time. Liquid application amount. Therefore, eliminating the glue hanging phenomenon of the nozzle is a key process link in high-pr...
