Abstract
The utility model relates to a spray jet of a powder sprayer, which comprises a casing body. The casing body is equipped with an air inlet, an air outlet, and an inlet channel connecting the air inlet with the air outlet. The utility model is characterized in that the air outlet has a flared shape with small inner part and large outer part, an eyelet hole is arranged on the outer wall of the flared air outlet, one end of the eyelet hole is connected with the flared air outlet, and the other end of the eyelet hole is connected with the outer space. Due to the flare shaped design of the air outlet, compressed air flows from the small outlet end to the large outlet end of the flared air outlet, and is ejected out, making the air flow mass platoid fan-shaped, meanwhile, the eyelet hole on the outer wall of the flared air outlet is connected with the outer space, and the speed of the air flow is quickened when the compressed air flows through the eyelet hole, to generate negative pressure inside the eyelet hole, and the outside air enters into the eyelet hole due to the function of the negative pressure, and then forms a certain amount of air flow level on the surface of the compressed air in the nozzle, to perform the functions of insulation, assistance and improving the ejecting effect of the main air flow (mixture air).
Description
Technical field:
The utility model relates to the chromatic printing machine system, is specifically related to a kind of nozzle that is used for the powder sprayer of chromatic printing machine system.
Background technology:
Because run up during printing machine work, the printing ink on the paper also be not superimposed under the situation of bone dry, and picture is polluted mutually, cause the quality of printing to descend.At this moment,, printing ink and other paper on the picture are separated, also play dry effect simultaneously if evenly spray the very thin fine powder of one deck on the surface of picture.But the mechanical dusting of available technology adopting exists powder to mix the shortcoming inhomogeneous, that the black amount of powder can not accurately be controlled etc. with air, can directly have influence on the quality of printing.
Summary of the invention:
The purpose of this utility model is to provide a kind of nozzle of powder sprayer, and it is more even to use this nozzle that powder and air are mixed, and improves the quality of final printing.
To achieve these goals, the technical solution of the utility model is as follows: a kind of nozzle of powder sprayer, comprise housing, this housing is provided with air inlet, and the gas outlet is communicated with the inlet channel of this air inlet and gas outlet, it is characterized in that this gas outlet is inner small and outside big tubaeform, this is tubaeform gas outlet microcephaly's outer wall is provided with aperture, and an end of aperture is communicated with this tubaeform gas outlet, and the other end of aperture is in communication with the outside.According to an embodiment of the present utility model, this gas outlet is flat sector structure, this gas outlet is an osculum by the inlet channel end, and outer boundary, this gas outlet end is big mouthful, is provided with a plurality of apertures that are in communication with the outside in the top and the bottom of this gas outlet respectively by the osculum place.
The working pressure air pump makes the mist that contains a certain amount of powder with air pressurized, is ejected to the printed article surface by this nozzle.Because the gas outlet is tubaeform design, compressed air flows to big opening end and ejection from the osculum end of tubaeform gas outlet, make the air-flow group of ejection be the fan-shaped form of flat, aperture on the outer wall of tubaeform gas outlet is in communication with the outside simultaneously, when Compressed Gas passes through osculum, air velocity is accelerated, make the inner negative pressure that produces of aperture, extraneous air is because suction function enters aperture, and Compressed Gas surface forms a certain amount of airflow layer in spout, plays isolation, assist, improve the ejection effect of primary air (mist).
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the B-B cutaway view of Fig. 1
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is elaborated.
A kind of nozzle of powder sprayer, comprise housing 1, this housing 1 is provided with air inlet 2, gas outlet 3, the inlet channel 1 that is communicated with this air inlet 2 and gas outlet 3 is characterized in that this gas outlet 3 for inner small and outside big tubaeform, and this is tubaeform gas outlet microcephaly's outer wall is provided with aperture 5, one end of aperture 5 is communicated with gas outlet 2, and the other end of aperture 5 is in communication with the outside.According to an embodiment of the present utility model, this gas outlet 3 is flat sector structure.This gas outlet 3 is an osculum by inlet channel 4 ends, and these gas outlet 3 outer boundary ends are big mouthful, promptly is respectively equipped with a plurality of apertures that are in communication with the outside by inlet channel 4 ends at the top of this gas outlet 3 and the osculum place of bottom.Preferably, these a plurality of hole diameters are 0.7mm～2mm, and quantity is 3～8.
