DESCRIPCIÓNDESCRIPTION
Boquilla mejorada para pistolas pulverizadoras pensada para pinturas y derivados, basada en transferencia de fluidosImproved nozzle for spray guns designed for paints and derivatives, based on fluid transfer
Objeto de la invenciónObject of the invention
La presente boquilla mejorada para pistolas pulverizadoras pensadas para pinturas y derivados basándose en transferencia de fluidos se refiere a la canalización precisa de líneas de aire presurizado y a la formación de mezcla en el exterior de la cabeza de la boquilla.The present improved nozzle for spray guns intended for paints and derivatives based on fluid transfer refers to the precise channeling of pressurized air lines and the formation of mixture on the outside of the head of the nozzle.
Antecedentes de la invenciónBACKGROUND OF THE INVENTION
En el mercado actual hay algunas pistolas pulverizadoras para pintar superficies con aire presurizado, véase por ejemplo el documento US 5.419 491. La mayor parte de estas funcionan de manera que el producto que va a pulverizarse se forma en el interior de una cámara de la pistola pulverizadora, donde el producto se une con el catalizador, de manera que cuando se está proyectando, el aire empuja y se mezcla con esta mezcla, que se pulveriza sobre la superficie que va a tratarse.In the current market there are some spray guns for painting surfaces with pressurized air, see for example US 5,419,991. Most of these operate so that the product to be sprayed is formed inside a gun chamber spray, where the product joins with the catalyst, so that when it is projecting, the air pushes and mixes with this mixture, which is sprayed on the surface to be treated.
Este sistema implica una serie de inconvenientes como el de mezclar en el interior de la propia pistola pulverizadora, o incluso, antes de su paso a través de las pistolas pulverizadoras, la mezcla catalizada se desplaza a través de los orificios y mecanismos de las pistolas pulverizadoras, bloqueando y dañando válvulas, pasos, etc., y llevando a una proyección irregular.This system involves a series of drawbacks such as mixing inside the spray gun itself, or even, before passing through the spray guns, the catalyzed mixture moves through the holes and mechanisms of the spray guns , blocking and damaging valves, steps, etc., and leading to an irregular projection.
Esta situación implica un coste de mantenimiento mayor y una durabilidad de equipo inferior, tanto para tubos como para accesorios. Además, la mezcla ya hecha pierde propiedades con el tiempo cuando no se pulveriza inmediatamente.This situation implies a higher maintenance cost and lower equipment durability, both for pipes and accessories. In addition, the mixture already made loses properties over time when it is not sprayed immediately.
Todo esto lleva a una reducción en la calidad de la pintura, el barnizado o cualquier trabajo realizado con estas pistolas pulverizadoras, una reducción del rendimiento de la misma y un desperdicio de material en el sentido de que la mezcla no usada en el momento sufre el riesgo de perderse.All this leads to a reduction in the quality of the paint, the varnishing or any work done with these spray guns, a reduction in the performance of the same and a waste of material in the sense that the mixture not used at the time suffers the risk of getting lost.
Además, como experimenta bloqueos y acumulaciones, es necesario usar productos tales como disolventes que liberan las líneas y las limpian, con la correspondiente emisión de gases y generación de residuos tóxicos y peligrosos de los mismos.In addition, as it experiences blockages and accumulations, it is necessary to use products such as solvents that release the lines and clean them, with the corresponding emission of gases and generation of toxic and dangerous waste thereof.
Con el fin de evitar algunos de estos inconvenientes, la marca Binks comercializa una pistola de pulverización que coloca una salida de aire en la boquilla, dirigida hacia el exterior de la misma, de manera que la resina se proyecta sobre un lado, el catalizador sobre otro para mezclar e independientemente el aire, de manera que la pulverización se realiza en un espacio enfrente de la boquilla en la dirección de la proyección.In order to avoid some of these drawbacks, Binks brand sells a spray gun that places an air outlet in the nozzle, directed towards the outside of it, so that the resin is projected on one side, the catalyst on another to mix and independently air, so that the spray is performed in a space in front of the nozzle in the direction of the projection.
Aunque soluciona algunos problemas mencionados, esta boquilla tiene un solo inyector de catalizador no pulverizado desde uno de los lados del chorro de resina, por tanto la mezcla pulverizada final no garantiza una homogeneidad completa.Although it solves some of the mentioned problems, this nozzle has a single non-pulverized catalyst injector from one side of the resin jet, therefore the final pulverized mixture does not guarantee complete homogeneity.
Descripción de la invenciónDescription of the invention
La boquilla mejorada para pistolas pulverizadoras pensadas para pinturas hechas de dos componentes y derivados basadas en la transferencia de fluidos, objeto de la presente invención, pretende mejorar los inconvenientes descritos anteriormente, con ese fin, tiene una cabeza con varias crestas de aire para proyectar los diferentes componentes que forman la nube pulverizada y varias salidas de aire que unen la proyección de los componentes anteriores en un punto enfrente de dicha cabeza, formándose, por tanto, un mezclado externo de resina y catalizador.The improved nozzle for spray guns designed for paints made of two components and derivatives based on the transfer of fluids, object of the present invention, aims to improve the drawbacks described above, for this purpose, has a head with several air crests to project the different components that form the pulverized cloud and several air outlets that join the projection of the previous components in a point opposite said head, forming, therefore, an external mixing of resin and catalyst.
La salida del catalizador, la resina, el aire presurizado y otro cualquiera de los componentes si los hay, se logra mediante varios orificios independientes de manera que todos los componentes se inyectan a la vez apretando el disparador y se crea una nube de mezcla pulverizada en el exterior de la boquilla.The output of the catalyst, the resin, the pressurized air and any other component if any, is achieved through several independent holes so that all the components are injected at the same time by pressing the trigger and creating a cloud of pulverized mixture in the outside of the mouthpiece.
Todas las líneas de catalizador y aire presurizado están mecanizadas en la propia boquilla, con las salidas de las mismas en las crestas de aire en ambos lados del orificio de salida central de la resina, dirigidas hacia un punto en el que todos los componentes convergen en el exterior de la pistola pulverizadora.All the lines of catalyst and pressurized air are machined in the nozzle itself, with the exits of the same in the air crests on both sides of the central exit orifice of the resin, directed towards a point where all the components converge in the outside of the spray gun.
Además, cada una de las salidas de la boquilla se regula en cuanto a flujo y presión, lo que favorece la regulación de la mezcla y su uso dependiendo del fin pretendido y la naturaleza de los componentes.In addition, each of the nozzle outputs is regulated in terms of flow and pressure, which favors the regulation of the mixture and its use depending on the intended purpose and the nature of the components.
Por tanto, el mezclado en el exterior evita daños mecánicos debidos a los productos que no catalizan en el interior de los mecanismos de bombeo y aplicación, obteniéndose una durabilidad de tubo y accesorio mayor.Therefore, mixing on the outside prevents mechanical damage due to products that do not catalyze inside of the mechanisms of pumping and application, obtaining a durability of tube and greater accessory.
Se proporciona en todo momento una mezcla más fresca con una pérdida de propiedades de mezcla menor dado que se mezcla en el momento de uso. También permite el uso de productos de 2 componentes de reacción instantánea que no puede realizarse de otra manera no manual.A fresher mix is provided at all times with a loss of minor mixing properties since it is mixed at the time of use. It also allows the use of 2-component products of instantaneous reaction that can not be carried out other than manual.
Produce un aumento en la calidad dado que la mezcla no permanece en un recipiente antes de la pulverización; por tanto, las partes mecánicas del sistema de pulverización no se deterioran ni se estropean.It produces an increase in quality since the mixture does not remain in a container before spraying; therefore, the mechanical parts of the spray system do not deteriorate or break down.
La boquilla propuesta implica un uso y un rendimiento mejores de los productos dado que no hay producto restante, es decir, sólo se usa la cantidad necesaria de producto. Facilita, adicionalmente, cambios de color más rápidos sin consumo de disolvente.The proposed nozzle implies a better use and performance of the products since there is no remaining product, that is, only the necessary amount of product is used. It facilitates, in addition, faster color changes without solvent consumption.
En general, esta boquilla no requiere limpieza dado que los componentes nunca se mezclan en el interior, por lo cual se evita el uso de disolventes de limpieza y la emisión de gases, no generando residuos tóxicos y peligrosos.In general, this nozzle does not require cleaning since the components are never mixed inside, thus avoiding the use of cleaning solvents and the emission of gases, not generating toxic and dangerous waste.

Realización preferida de la invenciónPreferred embodiment of the invention
Tal como puede observarse en los dibujos adjuntos, en primer lugar, se distingue un cuerpo (7) de boquilla, donde están ubicadas las crestas (8) de aire que tienen parte de los orificios de salida de aire y catalizador de la boquilla. Otras emisiones, tales como resina, se producen, a su vez, desde la zona central que es la salida (9) de producto. Los fluidos de resina y el catalizador u otros componentes se mezclan en el exterior de la boquilla, justo en el momento de uso. Con ese fin, la boquilla (7) incorpora una entrada para el catalizador (1), que se conecta con una serie de canales internos a través de los cuales circula el flujo de catalizador, terminando los canales internos por medio de orificios (2) de salida de catalizador, en la superficie externa de la misma, proyectándose el catalizador hacia el flujo de resina que sale a través del orificio (9) mezclándose con el último en el exterior.As can be seen in the attached drawings, first of all, a nozzle body (7) is distinguished, where the air crests (8) having part of the air outlet and catalyst ports of the nozzle are located. Other emissions, such as resin, are produced, in turn, from the central area, which is the output (9) of the product. Resin fluids and catalyst or other components are mixed on the outside of the nozzle, just at the time of use. For this purpose, the nozzle (7) incorporates an inlet for the catalyst (1), which is connected to a series of internal channels through which the catalyst flow circulates, terminating the internal channels by means of holes (2) of catalyst outlet, on the external surface thereof, the catalyst projecting towards the flow of resin leaving through the hole (9) mixing with the latter outside.
La boquilla (7) incorpora canales (4) de entrada de aire presurizado, que transportan el aire a través del interior de la boquilla y terminan en diferentes elementos en la superficie exterior de la boquilla, estos elementos están compuestos, por un lado, de salidas (5), en una primera fase, para pulverizar el abanico de resina y, por otro lado, de salidas (3), en una segunda fase, para pulverizar la nube del catalizador, ambas fases se mezclan de manera sincronizada en el exterior de la boquilla (7).The nozzle (7) incorporates channels (4) of pressurized air inlet, which transport air through the interior of the nozzle and end in different elements on the outer surface of the nozzle, these elements are composed, on the one hand, of outlets (5), in a first phase, to spray the resin fan and, on the other hand, outlets (3), in a second phase, to spray the catalyst cloud, both phases are mixed in a synchronized manner on the outside of the mouthpiece (7).
El elemento que genera la nube que pulveriza el catalizador (3) está formado por una pluralidad de orificios que rodean el de la salida (2) de catalizador, que pulverizan el catalizador. Dicho elemento (3) también puede estar formado por ranuras longitudinales o similares.The element that generates the cloud that pulverizes the catalyst (3) is formed by a plurality of holes that surround the one of the catalyst outlet (2), which pulverizes the catalyst. Said element (3) can also be formed by longitudinal grooves or the like.
El elemento que genera esta nube (3) de pulverización también puede estar formado por orificios o ranuras que están conectados directamente con el exterior de la boquilla (6), con el propósito de obtener un suministro de aire extra desde el exterior mediante el efecto Venturi, para lograr una pulverización mejor.The element that generates this spray cloud (3) can also be formed by holes or slots that are directly connected to the outside of the nozzle (6), with the purpose of obtaining an extra air supply from the outside through the Venturi effect. , to achieve a better spray.
Las crestas (8) de aire sobresalen desde el plano de la boquilla y están dispuestas de manera que favorecen la formación de la nube pulverizada de la mezcla de componente y aire.The air ridges (8) protrude from the plane of the nozzle and are arranged so as to favor the formation of the pulverized cloud of the component and air mixture.
Su uso y funcionamiento es bastante sencillo, con ese fin la boquilla (7) se coloca en la pistola pulverizadora, estando conectadas la salida (9) de resina y la salida (4) de aire presurizado, por tanto, a la pistola pulverizadora, de manera que el aire presurizado se desplaza a través del canal (4) interno a los orificios de pulverización de la primera fase (5) y la segunda fase (3). El catalizador está conectado externamente a la línea (1), y se activará por medio de una válvula externa presionando el disparador, o mediante una señal electroneumática si es una pistola de pulverización automática, de manera que el catalizador se desplaza a través del canal interno hasta la salida (2) que, de manera similar al del aire (3), también puede estar formado por ranuras o similares. Its use and operation is quite simple, for that purpose the nozzle (7) is placed in the spray gun, the resin outlet (9) and the outlet (4) of pressurized air being connected, therefore, to the spray gun, so that the pressurized air moves through the internal channel (4) to the spray orifices of the first phase (5) and the second phase (3). The catalyst is connected externally to the line (1), and will be activated by means of an external valve pressing the trigger, or by an electropneumatic signal if it is an automatic spray gun, so that the catalyst moves through the internal channel to the outlet (2) which, similarly to the air (3), can also be formed by grooves or the like.
Cuando se presiona el disparador de la pistola pulverizadora, por un lado se proyecta la resina a través de su salida (9) y el aire dirigido hacia el chorro de resina proyectado a través del elemento de la primera fase (5), creándose, por tanto, la pulverización del mismo en la parte externa de la boquilla en la dirección hacia la superficie que va a tratarse.When the trigger of the spray gun is pressed, on the one hand the resin is projected through its outlet (9) and the air directed towards the jet of resin projected through the element of the first phase (5), being created, by both, spraying it on the outside of the nozzle in the direction towards the surface to be treated.
Si se requiere adicionalmente el uso de un catalizador además del producto mencionado, el último se proyecta a través de los orificios (2) de manera que su proyección se une en la del producto o resina, o en las inmediaciones de la misma. Al mismo tiempo, el aire también fluye desde el elemento (3) hacia el mismo punto de unión, por lo cual el producto se pulveriza, por un lado, con el aire del elemento (5) y el catalizador con el del elemento (3), favoreciendo esta situación una nube de mezcla muy difundida como resultado de la cantidad de aire recibido y la dispersión e incidencia en el chorro principal obtenido mediante la disposición de las bocas que forman ambos de los elementos (3) y (5).If the use of a catalyst in addition to the aforementioned product is additionally required, the latter is projected through the holes (2) so that its projection is joined to that of the product or resin, or in the vicinity thereof. At the same time, air also flows from the element (3) to the same point of attachment, whereby the product is sprayed, on the one hand, with the air of the element (5) and the catalyst with that of the element (3). ), favoring this situation a cloud of very widespread mixture as a result of the amount of air received and the dispersion and incidence in the main jet obtained by the arrangement of the mouths that form both of the elements (3) and (5).
La boquilla (7) está dotada de una serie de orificios (6) no presurizados que se muestran, por un lado, comunicados con el exterior y, por otro, en comunicación con las líneas de suministro de aire presurizado hasta el elemento de la segunda fase (3) para suministrar aire al catalizador o al elemento de la primera fase (5) para suministrar aire a la resina.The nozzle (7) is provided with a series of non-pressurized holes (6) that are shown, on the one hand, communicated with the outside and, on the other, in communication with the supply lines of pressurized air to the element of the second phase (3) to supply air to the catalyst or to the element of the first phase (5) to supply air to the resin.
El objetivo de estos orificios (6) externos se encuentra en que permitan el acceso de aire desde el exterior, como un suministro extra cuando la pistola pulverizadora y los elementos de la segunda fase (3) o primera fase (5) se activan mediante el efecto Venturi, tirando del aire del exterior provocado por la salida a través del elemento (3) o (5). Por tanto, se logra una mejor pulverización debido a una inyección extra de flujo de aire sin consumo de energía adicional. Este efecto Venturi también puede aplicarse a pistolas pulverizadoras de un solo componente donde sólo se pulveriza un producto a través de la salida (9), mejorando la pulverización.The aim of these external holes (6) is that they allow access 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 activated by the Venturi effect, pulling the air from the outside caused by the exit through the element (3) or (5). Therefore, better spraying is achieved due to an extra injection of air flow without additional energy consumption. This Venturi effect can also be applied to single component spray guns where only one product is sprayed through the outlet (9), improving spraying.
En el caso de usar pinturas o resinas con un solo componente, los orificios de la segunda fase (3) estarán vacíos, dado que el orificio de salida (2) de catalizador no estará operativo.In the case of using paints or resins with a single component, the holes of the second phase (3) will be empty, since the catalyst exit orifice (2) will not be operative.
Una vez que la naturaleza de la presente invención además de un uso práctico de la misma están suficientemente descritas, simplemente queda añadir que la forma y los materiales además de la ejecución de la misma son susceptibles a modificaciones, dado que no afectan a las características reivindicadas a continuación: Once the nature of the present invention in addition to a practical use thereof is sufficiently described, it simply remains to add that the form and the materials in addition to the execution thereof are susceptible to modifications, since they do not affect the claimed characteristics then:
