Four crisscross channels are formed at one section of the end of the cylindrical spray nozzle base, and a circular spray nozzle and an oval spray nozzle are inlaid in two adjacent channels respectively so that the circular spray nozzle and the oval spray nozzle are in cross distribution with the angle of 90 degrees; the spray nozzle base is connected with a spray head protective cover through a left snap ring and a right snap ring. The spray nozzle of the airless spray gun integrates three types of spray nozzles such as the circular spray nozzle, the oval spray nozzle and a self-cleaning spray nozzle; under the guide action of semicircular track grooves in the left snap ring and the right snap ring, when different graph spraying widths need to be used, the spray nozzle only needs to be rotated by 90 degrees instead of being replaced, then the needed spraying widths can be obtained, back flushing and self-cleaning can be achieved through 180-degree rotation, and the spray nozzle is convenient to operate, simple and practical.
Description
Technical field
The present invention relates to a kind of nozzle, be specifically related to a kind of airless spray gun nozzle.
Background technology
Airless spraying technology is compared with brushing, aerial spraying, has following characteristics: coating efficiency is high; To dope viscosity wide accommodation; When spraying thick-film coating, once spraying can obtain thicker filming, thereby reduces spraying number of times; Painting quality is good, the disadvantage that can avoid moisture in compressed air, oil droplet, dust to cause paint film; Without air atomizing, it is few that paint film disperses, and thick-film coating solids content is high, can add less even not add diluent and get final product direct spraying, thereby reduce the pollution to environment.
In airless spraying technology, nozzle is the parts of airless spray gun most critical.Because airless spray gun does not have the governor motion of coating spray volume (flow) and spray pattern fabric width (spraying swath), so can only reach by changing nozzle the object of adjust flux and spraying swath.
Existing airless spray gun nozzle is divided into the several types such as round nozzle, oval nozzle, certainly clear type nozzle.
Round nozzle is as shown in Figure 1 a, 1 b mainly used in spraying inner-walls of duct and other narrow positions; The opening of round nozzle is rounded.
Oval nozzle as shown in Fig. 2 a, Fig. 2 b is used the most general, and the opening of oval nozzle is olive shape, spray pattern ovalize.
Certainly clear type nozzle is as shown in Figure 3 provided with a commutating structure, and when nozzle is blocked, Rotate 180 ° can wash out tamper; This nozzle has spherical and cylindrical two kinds, but with cylindrical comparatively conventional.
The function singleness of above-mentioned several nozzles, in order to obtain the spraying swath of different graphic, needs the frequent dissimilar nozzle of changing, and uses inconvenience.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of airless spray gun nozzle, and it can be suitable for different work spraying swath requirements when spraying operation.
For solving the problems of the technologies described above, the technical solution of airless spray gun nozzle of the present invention is:
Comprise cylinder nozzle carrier, end one section of cylinder nozzle carrier forms four passages of right-angled intersection, wherein in two adjacent passages, be inlaid with respectively a round nozzle and an oval nozzle, so that cross-distribution in 90 ° between round nozzle and oval nozzle; Nozzle carrier connects shower nozzle guard shield by left and right snap ring; Left and right snap ring is comprised of two semicircle snap rings, and one end of two semicircle snap rings is with button fastening, and the other end is fastening by snap ring cap; The curved portions inner side of semicircle snap ring forms semicircle rail groove; Semicircle rail groove can provide guiding for the rotation of nozzle carrier; On nozzle carrier, be provided with two salient points, two salient points are corresponding to the opening of semicircle rail groove, and insert shower nozzle guard shield.
Described round nozzle is fixedly connected with the access bore of nozzle carrier by nozzle pad, nozzle mold insert respectively with oval nozzle
The other end of described nozzle carrier is provided with cross handle, is beneficial to nozzle carrier with respect to the rotation of left and right snap ring.
Described cross handle is provided with the shape corresponding to round nozzle and oval nozzle, understands the state of nozzle by the shape on cross handle.
Described cylinder nozzle carrier is formed by stainless steel fine grinding.
Described round nozzle and oval nozzle adopt wearable hard alloy to make.
The technique effect that the present invention can reach is:
The present invention can either be sprayed circular and oval figure, can realize again the function from clear type nozzle, and the tamper on nozzle is washed out.
The present invention is integrated round nozzle, oval nozzle, from the nozzle of clear type nozzle three types, and by the guide effect of left and right first circular rail groove of snap ring, when being used different graphic spraying swath, needs need not change nozzle, the spraying swath that nozzle half-twist just can need only be wanted, Rotate 180 ° can be realized recoil from clear, handled easily, simple and practical.

The specific embodiment
As shown in Figure 4, airless spray gun nozzle of the present invention, comprise cylinder nozzle carrier 1, end one section of cylinder nozzle carrier 1 forms four passage a, b, c, the d of right-angled intersection, wherein in two adjacent passage a, b, be inlaid with respectively a round nozzle and an oval nozzle 2, so that cross-distribution in 90 ° between round nozzle and oval nozzle;
Round nozzle is fixedly connected with the access bore of nozzle carrier 1 by nozzle pad 21, nozzle mold insert 22 respectively with oval nozzle 2;
Nozzle carrier 1 connects shower nozzle guard shield 3 by left and right snap ring 4; Left and right snap ring 4 is comprised of two semicircle snap rings, and one end of two semicircle snap rings is with button fastening, and the other end is fastening by snap ring cap 41; Two semicircle snap rings are fixed on shower nozzle guard shield 3; The curved portions inner side of semicircle snap ring forms semicircle rail groove; Semicircle rail groove can provide guiding for the rotation of nozzle carrier 1, when nozzle carrier 1 enters shower nozzle guard shield 3, by left and right snap ring 4, is led; On nozzle carrier 1, be provided with two salient points, two salient points are corresponding to the opening of semicircle rail groove, and insert shower nozzle guard shield 3;
The other end of nozzle carrier 1 is provided with cross handle, is beneficial to nozzle carrier 1 with respect to the rotation of left and right snap ring; Cross handle is provided with the shape corresponding to round nozzle and oval nozzle, understands the state of nozzle by the shape on cross handle.
Cylinder nozzle carrier 1 is formed by high-quality stainless steel fine grinding, and sealing property is good, to be applicable to the coating of different medium.
Because round nozzle and oval nozzle very easily wear and tear, once that nozzle bore becomes is large, film super thick and inhomogeneous, not only increase paint consumption, but also can make paint vehicle be difficult to be dried, affect manufacturing schedule; As bad in nozzle material and cause wearing and tearing, spray orifice to become large and justify, ejection coating is fan-shaped and diminish, and flow increase have a strong impact on presentation quality and the thickness quality of paint film, so the quality of nozzle material is most important to the service life of nozzle and spraying swath quality.Round nozzle of the present invention and oval nozzle adopt wearable hard alloy to make, and are applicable to the spraying of high viscosity, high density and zinc-rich paint, can improve service life.
Operation principle of the present invention is as follows:
As shown in Figure 5 a to 5 c, when round nozzle makes progress, nozzle sprays circular spraying swath; Make nozzle carrier 1 Rotate 180 °, now round nozzle is downward, as shown in Fig. 7 a to Fig. 7 c, can wash out the tamper on round nozzle, reaches the object of self-cleaning;
Make nozzle carrier 1 half-twist, now oval nozzle upwards, as shown in Fig. 6 a to Fig. 6 c, can change oval spraying swath into from circular spraying swath; Make nozzle carrier 1 Rotate 180 ° again, now oval nozzle is downward, as shown in Fig. 8 a to Fig. 8 c, can wash out the tamper on oval nozzle, reaches the object of self-cleaning.
