Description

    Object of the Invention
  • The present improved nozzle for spray guns intended for paints and derivatives based on fluid transfer relates to the precise channeling of pressurized air lines and formation of mixture outside the head of the nozzle.
    • Background of the Invention
  • In the current market there are some spray guns for painting surfaces with pressurized air, see e.g. document US 5,419 491 . Most of these work such that the product to be sprayed is formed inside a chamber of the spray gun, where the product meets with the catalyst, such that when being projected, the air pushes and it is mixed with this mixture, being sprayed on the surface to be treated.
  • This system involves a series of drawbacks like that of mixing inside the spray gun itself, or including, prior to its passage through the spray guns, the catalyzed mixture travels through the holes and mechanisms of the spray guns, blocking and damaging valves, passages, etc., and leading to an irregular projection.
  • This situation involves a greater maintenance cost and a lower equipment durability, both for the tubes and accessories. In addition, the already made mixture loses properties with time when not immediately sprayed.
  • All this leads to a reduction in the quality of the painting, varnishing, or any of the work performed with these spray guns, a reduction of the performance thereof and a waste of material in the sense that the mixture not used at the time suffers the risk of being lost.
  • Furthermore, as it experiences blockages and build-ups, using products such as solvents which free up the lines and cleaning them is necessary, with the corresponding emission of gases and generation of toxic and dangerous wastes thereof.
  • In order to prevent some of these drawbacks, the brand Binks markets a spray gun which places an air outlet in the nozzle, directed towards the outside thereof, such that the resin is projected on one side, the catalyst on another for mixing and independently the air, such that the spraying is performed in a space in front of the nozzle in the direction of the projection.
  • Although it solves some mentioned problems, this nozzle has a single unsprayed catalyst propeller from one of the sides of the resin jet, therefore the final sprayed mixture does not assure a complete homogeneity.
    • Description of the Invention
  • The improved nozzle for spray guns intended for paints made up of two components and derivatives based on fluid transfer, object of the present invention intends to improve the drawbacks described above, to that end, it has a head with several air crests for projecting the different components forming the sprayed cloud and several air outlets meeting the projection of the previous components at a point in front of said head, an external mixing of resin and catalyst thus being performed.
  • The exit of the catalyst, the resin, the pressurized air and any other of the components if any, is achieved by several independent holes such that all the components are injected in unison by tightening the trigger and a sprayed mixture cloud is created outside the nozzle.
  • All the pressurized air and catalyst lines are machined in the nozzle itself, with the outlets thereof in the air crests on both sides of the central outlet hole of the resin, directed towards a point where all the components converge outside of the spray gun.
  • Furthermore, each of the outlets of the nozzle is regulated in flow and pressure, which favors the regulation of the mixture and its use depending on the intended finish and the nature of the components.
  • Therefore mixing on the outside prevents mechanical damages due to the products not catalyzing inside the pumping and applying mechanisms, a greater tube and accessory durability being obtained.
  • A fresher mixture with less mixture property loss since it is mixed at the time of use is provided at all times. It also allows the use of products of 2 instant reaction components which could not be performed in otherwise non-manual manner.
  • It produces an increase in quality since the mixture does not remain in a container prior to spraying; therefore mechanical parts of the spraying system do not deteriorate nor break down.
  • The proposed nozzle involves a better performance and use of the products since there is no remaining product, i.e., only the needed amount of product is used. It further facilitates quicker color changes without solvent consumption.
  • In general this nozzle does not require cleaning since the components are never mixed inside, whereby the use of cleaning solvents and the emission of gases is prevented, not generating toxic and dangerous wastes.
    • Description of the Drawings
  • To complement the description that is being made and for the purpose of aiding to better understand the features of the invention, a set of drawings is attached as an integral part of the present specification in which the following has been depicted with an illustrative and non-limiting character:
    • Figure 1 shows an upper side perspective view of the nozzle object of the present invention.
    • Figure 2 shows a lower side perspective view of the previous nozzle.
    • Figure 3 shows a plan view of the nozzle.
    • Figure 4 shows a side perspective view of the previous nozzle.
    Preferred Embodiment of the Invention
  • As can be seen in the attached drawings, first a nozzle (7) body is distinguish, where the air crests (8) having part of the air and catalyst outlet holes of the nozzle are located. Other emissions such as resin, are in turn produced from the central area which is the product outlet (9).
  • The resin fluids and the catalyst or other components are mixed outside the nozzle, right at the time of use. To that end the nozzle (7) incorporates an inlet for the catalyst (1), connecting with a series of internal channels through where the catalyst flow circulates, which internal channels end by means of catalyst outlet holes (2), on the outer surface thereof, the catalyst projecting towards the resin flow exiting through the hole (9) being mixed with the latter outside.
  • The nozzle (7) incorporates pressurized air inlet channels (4), conveying the air through the inside of the nozzle and they end in different elements at the outer surface of the nozzle, these elements are made up on one hand of outlets (5), in a first phase, for spraying the resin fan and on the other hand of outlets (3), in a second phase, for spraying the cloud of the catalyst, both phases are mixed in a synchronized manner outside the nozzle (7).
  • The element generating the cloud which sprays the catalyst (3), is formed by a plurality of holes surrounding that of the catalyst (2) outlet, spraying the catalyst. Said element (3) can also be formed by longitudinal grooves or the like.
  • The element generating this spraying cloud (3) can also be formed by holes or grooves which are directly connected with the outside of the nozzle (6), for the purpose of obtaining an extra air supply from the outside by Venturi effect, to achieve a better spraying.
  • The air crests (8) protrude from the plane of the nozzle and are arranged in the manner favoring the formation of the sprayed cloud of the component and air mixture.
  • Its use and operation is quite simple, to that end the nozzle (7) is placed on the spray gun, the resin outlet (9) and the pressurized air outlet (4) thus being connected to the spray gun, such that the pressurized air travels through the internal channel (4) to the spraying holes of the first phase (5) and the second phase (3). The catalyst is externally connected to the line (1), and it will be activated by means of an external valve by pressing the trigger, or by a electric-pneumatic signal if it is an automatic spray gun, such that the catalyst travels through the internal channel to the outlet (2) which, similar to that of the air (3), may also be formed by grooves or the like.
  • When the trigger of the spray gun is pressed, on one side the resin is projected through its outlet (9) and the air directed towards the projected resin jet through the element of the first phase (5), the spraying thereof thus being created at the outer part of the nozzle in the direction towards the surface to be treated.
  • If the use of a catalyst is further required in addition to the mentioned product, the latter is projected through the holes (2) such that its projection meets at that of the product or resin, or in the vicinity thereof. At the same time the air also flows from the element (3) towards the same meeting point, whereby the product is on one hand sprayed with the air of the element (5) and the catalyst with that of the element (3), this situation favoring a very diffused mixture cloud as a result of the amount of air received and the dispersion and incidence on the main jet obtained by arranging the spouts forming both the elements (3) and (5).
  • The nozzle (7) is provided with a series of non-pressurized holes (6) which are shown, on one hand, communicated with the outside and on the other in communication with the pressurized air supply lines to the element of the second phase (3) for supplying air to the catalyst or to the element of the first phase (5) for supplying air to the resin.
  • The objective of these outer holes (6) lies in that they enable the entrance of air from the outside, as an extra supply when the spray gun and the elements of the second phase (3) or first phase (5) are active by the Venturi effect, by pulling the outside air caused by the exit through the element (3) or (5). A better spraying due to an extra injection of air flow without additional energy consumption thus being achieved. This Venturi effect can also be applied to single-component spray guns where only product is sprayed through the outlet (9) improving the spraying.
  • In the case of using paints or resins with a single component, the holes of the second phase (3) would be void, since the catalyst outlet hole (2) would not be operational.
  • Once the nature of the present invention as well as a practical use thereof are sufficiently described, it merely remains to be added that the form and materials as well as execution thereof are susceptible to modifications, provided that they do not affect the features claimed below:
