Description

Technical Field

[0001] This invention relates to the field of anti-clogging technology for atomizing nozzles, and more specifically, to an anti-clogging cast aluminum spray gun spiral atomizing nozzle. Background Technology

[0002] Currently, in industrial production processes such as aluminum casting, the atomizing nozzle of the spray gun is a key component for achieving uniform spraying of media (such as coatings, cleaning agents, etc.). However, in the long-term use of existing spray gun atomizing nozzles, impurities and particles contained in the media often clog the nozzle channel, leading to reduced atomization effect, uneven spraying, and even affecting production efficiency and product quality.

[0003] Meanwhile, the traditional nozzle's filter structure design is inadequate, leading to easy accumulation of impurities in the filter components and making cleaning difficult. Frequent disassembly and cleaning are required, increasing maintenance costs and downtime. Furthermore, the connection structure of some nozzles lacks stability and may loosen under high-pressure injection conditions, further exacerbating clogging problems and increasing equipment failure risks. This makes it difficult to meet the demands of industrial production for efficient, stable, and low-maintenance nozzles. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a spiral atomizing nozzle for anti-clogging cast aluminum spray guns, which aims to improve the problem that the filter structure design of traditional nozzles is not reasonable, the filter components are prone to accumulating impurities and are difficult to clean.

[0005] The present invention is implemented as follows: a spiral atomizing nozzle for an anti-clogging cast aluminum spray gun includes a connecting pipe, a guide pipe, and an atomizing threaded nozzle. The threaded nozzle is fixedly installed at one end of the guide pipe, and the connecting pipe is threadedly installed at the other end of the guide pipe. A support ring is fixedly installed on the inner wall of the guide pipe, and a filter plate is snapped into the support ring. A compression ring that mates with the filter plate is installed on the inner wall of the connecting pipe. A cleaning component that mates with the filter plate is installed inside the connecting pipe. A fixing component is installed outside the connecting pipe and the guide pipe.

[0006] In a preferred embodiment of the present invention, a support plate is fixedly installed on the outside of the connecting pipe, and the four corners of the support plate are arc-shaped.

[0007] In a preferred embodiment of the present invention, the fixing component includes a first positioning ring, a second positioning ring, and insert rods. The first positioning ring and a third positioning ring are fixedly installed on the outside of the connecting pipe. An elastic telescopic rod is symmetrically fixedly installed at the bottom end of the first positioning ring. The output end of the elastic telescopic rod is fixedly connected to one side of the third positioning ring. A plurality of insert rods are fixedly installed at the bottom end of the third positioning ring. The second positioning ring is fixedly sleeved on the outside of the conduit. The second positioning ring is provided with insertion holes that match the insert rods. The plurality of insert rods correspond one-to-one with the plurality of insertion holes and are slidably connected to their inner walls.

[0008] In a preferred embodiment of the present invention, the elastic telescopic rod is composed of a sleeve rod and a pull rod. The sleeve rod is fixedly installed at the bottom end of the first positioning ring, a spring is fixedly installed on the inner wall of the sleeve rod, the pull rod is fixedly installed at the bottom end of the spring, the bottom end of the pull rod is fixedly connected to the top end of the second positioning ring, and the pull rod is slidably connected to the inner wall of the sleeve rod.

[0009] In a preferred embodiment of the present invention, a plurality of pull blocks are fixedly installed at the top of the third positioning ring. The pull blocks are L-shaped and are staggered with the elastic telescopic rod.

[0010] In a preferred embodiment of the present invention, a plurality of anti-slip strips are fixedly installed on the outside of the conduit. The two sides of the anti-slip strips are arc-shaped, and the plurality of anti-slip strips are installed circumferentially and equidistantly on the outside of the conduit.

[0011] In a preferred embodiment of the present invention, the cleaning component includes a bracket, a first rotating shaft, and a scraper. The bracket is fixedly installed on the inner wall of the connecting pipe. The bracket is L-shaped. The first rotating shaft is rotatably installed at the bottom end of the bracket. The scraper is fixedly installed at the bottom end of the first rotating shaft. The scraper is in contact with the top end of the filter plate. A driving component is installed at the top end of the scraper. The inner wall of the extrusion ring is inclined. The scraper is slidably connected to the inner wall of the extrusion ring. The top end of the bracket is also inclined.

[0012] In a preferred embodiment of the present invention, the drive assembly includes a servo motor, a second rotating shaft, and a third rotating shaft. The bracket is hollow, and the second rotating shaft and the third rotating shaft are rotatably mounted between the two sides of the inner wall of the bracket. The bottom end of the second rotating shaft passes through the bracket and is fixedly connected to the first rotating shaft. A worm gear is fixedly mounted on the second rotating shaft, and a worm is fixedly mounted on the third rotating shaft. The worm gear and the worm are connected by a transmission. The servo motor is fixedly mounted on the outside of the connecting tube. The output end of the servo motor passes through the connecting tube and is fixedly connected to one end of the third rotating shaft. A protective shell is fixedly mounted on the outside of the connecting tube, and the protective shell is fitted over the outside of the servo motor.

[0013] The beneficial effects of this invention are:

[0014] Significant anti-clogging effect: By setting a filter plate inside the guide tube, impurities in the medium can be effectively intercepted, preventing impurities from directly entering the threaded nozzle and causing blockage; at the same time, the scraper in the cleaning component, driven by the drive component (servo motor, worm gear transmission, etc.), can continuously scrape and clean the surface of the filter plate, preventing impurities from accumulating, greatly reducing the probability of blockage, and extending the continuous working time of the nozzle.

[0015] High structural stability: Based on the threaded connection between the connecting pipe and the conduit, it is further reinforced with a fixing component—the elastic telescopic rod pushes the insertion rod of the third positioning ring into the insertion hole of the second positioning ring, forming a double fixation, which effectively prevents loosening under high pressure conditions and ensures the stability of the spraying process.

[0016] High ease of maintenance: The anti-slip strip on the outside of the conduit makes it easy to grip and disassemble. The L-shaped pull block on the third positioning ring can easily pull the plug rod out of the insertion hole, making it easy to quickly separate the connecting pipe and the conduit, and then replace or deeply clean the filter plate. The inclined design of the inner wall of the squeezing ring, combined with the sliding of the scraper, allows the scraped impurities to be discharged smoothly, reducing the amount of manual cleaning work.

[0017] Improved safety and practicality: The support plate on the outside of the connecting pipe enhances the overall structural strength, and its arc-shaped four corners prevent damage from sharp edges; the protective shell on the outside of the servo motor effectively protects the drive components and extends the service life of the equipment; the filter plate is snapped together by the support ring, and with the limiting of the compression ring, it ensures both filtration effect and easy installation and fixation.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-5 The present invention provides a technical solution: a spiral atomizing nozzle for an anti-clogging cast aluminum spray gun, comprising a connecting pipe 110, a guide pipe 120, and an atomizing threaded nozzle 130. The threaded nozzle 130 is fixedly installed at one end of the guide pipe 120, and the connecting pipe 110 is threadedly installed at the other end of the guide pipe 120. A support ring 121 is fixedly installed on the inner wall of the guide pipe 120, and a filter plate 122 is snapped into the support ring 121. A compression ring 111 that cooperates with the filter plate 122 is installed on the inner wall of the connecting pipe 110. A cleaning component that cooperates with the filter plate 122 is installed inside the connecting pipe 110. A fixing component is installed outside the connecting pipe 110 and the guide pipe 120.

[0028] In some specific implementation schemes, a support plate 112 is fixedly installed on the outside of the connecting pipe 110. The four corners of the support plate 112 are arc-shaped. The support plate 112 enhances the installation firmness during operation and reduces loosening of the connection due to factors such as vibration. At the same time, the arc-shaped design of the four corners of the support plate 112 can avoid the edges and corners being too sharp and causing injury to the operator, thus improving the safety of use.

[0029] In some specific implementation schemes, multiple anti-slip strips 123 are fixedly installed on the outside of the conduit 120. The two sides of the anti-slip strips 123 are arc-shaped, and the multiple anti-slip strips 123 are installed in a ring at equal intervals on the outside of the conduit 120 to prevent slippage when installing, disassembling or adjusting the conduit 120, thereby improving the stability and safety of operation. In addition, the arc-shaped design on both sides of the anti-slip strips 123 can prevent their edges from being too sharp and scratching the operator's hands, thus enhancing the comfort of use.

[0030] Please see Figure 2 and Figure 3 The fixing assembly includes a first positioning ring 140, a second positioning ring 141, and a plug rod 142. The first positioning ring 140 is fixedly installed on the outside of the connecting pipe 110, and a third positioning ring 143 is slidably installed. An elastic telescopic rod 144 is symmetrically fixedly installed at the bottom end of the first positioning ring 140. The output end of the elastic telescopic rod 144 is fixedly connected to one side of the third positioning ring 143. Multiple plug rods 142 are fixedly installed at the bottom end of the third positioning ring 143. The second positioning ring 141 is fixedly sleeved on the outside of the conduit 120. The second positioning ring 141 is provided with insertion holes that match the plug rods 142. The multiple plug rods 142 correspond one-to-one with the multiple insertion holes and are slidably connected to their inner walls. The elastic telescopic rod 144 pushes the third positioning ring 143 to insert the insertion rod 142 into the insertion hole of the second positioning ring 141, forming a double fixation, which effectively prevents the relative rotation or loosening of the connecting pipe 110 and the conduit 120 under high pressure conditions, ensuring the stability of the medium transportation and atomization process; and the insertion rod 142 and the insertion hole are slidably connected one-to-one, ensuring the precise fit of the fixed structure and the convenience of disassembly and assembly.

[0031] In some specific implementation schemes, the elastic telescopic rod 144 consists of a sleeve rod and a pull rod. The sleeve rod is fixedly installed at the bottom end of the first positioning ring 140, a spring is fixedly installed on the inner wall of the sleeve rod, and the pull rod is fixedly installed at the bottom end of the spring. The bottom end of the pull rod is fixedly connected to the top end of the second positioning ring 141, and the pull rod is slidably connected to the inner wall of the sleeve rod. The sliding connection between the pull rod and the inner wall of the sleeve rod ensures the smoothness of the extension and retraction process of the elastic telescopic rod 144. Moreover, this structure is simple, low-cost, easy to maintain, and can meet the needs of long-term, high-frequency use.

[0032] In some specific implementations, multiple pull blocks 145 are fixedly installed at the top of the third positioning ring 143. The pull blocks 145 are L-shaped and are staggered with the elastic telescopic rod 144. This allows for manual pulling of the third positioning ring 143 to compress the elastic telescopic rod 144, causing the insertion rod 142 to disengage from the insertion hole, thereby quickly separating the connecting pipe 110 and the guide pipe 120, facilitating the cleaning or replacement of components such as the filter plate 122. The staggered arrangement of the pull blocks 145 and the elastic telescopic rod 144 avoids mutual interference between them during movement, ensuring smooth operation.

[0033] Please see Figure 6The cleaning assembly includes a bracket 150, a first rotating shaft 151, and a scraper 152. The bracket 150 is fixedly installed on the inner wall of the connecting pipe 110. The bracket 150 is L-shaped, and the first rotating shaft 151 is rotatably installed at the bottom of the bracket 150. The scraper 152 is fixedly installed at the bottom of the first rotating shaft 151. The scraper 152 is in contact with the top of the filter plate 122, and a drive assembly is installed at the top of the scraper 152. The inner wall of the squeezing ring 111 is inclined, and the scraper 152 is slidably connected to the inner wall of the squeezing ring 111. The top of the bracket 150 is also inclined. This effectively removes impurities from the filter plate 122, preventing impurities from accumulating and clogging. At the same time, the inclined inner wall of the squeezing ring 111 and its slidable connection with the scraper 152 facilitates the discharge of impurities scraped by the scraper 152 along the inclined surface, avoiding secondary clogging caused by residual impurities and ensuring the continuous filtration effect of the filter plate 122.

[0034] In some specific implementations, the drive assembly includes a servo motor 153, a second rotating shaft 154, and a third rotating shaft 155. The bracket 150 is hollow. The second rotating shaft 154 and the third rotating shaft 155 are rotatably mounted between the two sides of the inner wall of the bracket 150, respectively. The bottom end of the second rotating shaft 154 passes through the bracket 150 and is fixedly connected to the first rotating shaft 151. A worm gear is fixedly mounted on the second rotating shaft 154, and a worm is fixedly mounted on the third rotating shaft 155. The worm gear and the worm are connected by a transmission. The servo motor 153 is fixedly mounted on the outside of the connecting pipe 110. The output end of the servo motor 153 passes through the connecting pipe 110 and is fixedly connected to one end of the third rotating shaft 155. A protective shell is fixedly mounted on the outside of the connecting pipe 110, and the protective shell is fitted over the outside of the servo motor 153. Worm gear transmission features precise transmission ratio and good self-locking properties, ensuring accurate control of the scraper 152's rotation angle and improving cleaning performance. The hollow bracket 150 provides installation space for the second shaft 154 and the third shaft 155, making the structure more compact. The protective shell on the outside of the connecting pipe 110 covers the outside of the servo motor 153, effectively protecting the servo motor 153 from external dust, media, and other corrosion, extending its service life, and ensuring the long-term stable operation of the drive components.

[0035] Working principle: Liquid enters through connecting pipe 110 and, before entering conduit 120, is filtered by a filter plate 122 engaged within a support ring 121 on the inner wall of conduit 120. The filter plate 122 intercepts impurities in the medium, preventing them from entering subsequent structures and causing blockages. A compression ring 111 on the inner wall of connecting pipe 110 cooperates with the filter plate 122, providing a certain degree of fixation and limiting for the filter plate 122. Simultaneously, after the servo motor 153 starts, its output drives the third rotating shaft 155 to rotate. The worm gear on the third rotating shaft 155 is connected to the worm wheel on the second rotating shaft 154, causing the second rotating shaft 154 to rotate. The second rotating shaft 154 drives the first rotating shaft 151 to rotate, thereby causing the scraper 152 to rotate at the top of the filter plate 122, scraping away impurities adhering to the filter plate 122. The scraper 152 is slidably connected to the inner wall of the inclined compression ring 111. This ensures that the scraped impurities are discharged smoothly; the filtered medium is transported to the atomizing threaded nozzle 130 through the conduit 120, and sprayed out after atomization by the threaded nozzle 130; during the operation of the entire device, the connecting pipe 110 and the conduit 120 are further fixed by the fixing assembly. The elastic telescopic rod 144 in the fixing assembly (composed of a sleeve rod, a pull rod and a spring) pushes the third positioning ring 143 downward under the elastic force of the spring, so that the insertion rod 142 at the bottom of the third positioning ring 143 is inserted into the insertion hole on the second positioning ring 141, thereby strengthening the stability of the connection between the connecting pipe 110 and the conduit 120. The support plate 112 can support the connecting pipe 110. The anti-slip strip 123 on the outside of the conduit 120 makes it easy for the operator to hold the conduit 120. The pull block 145 makes it easy for the operator to pull the third positioning ring 143 to disassemble the connecting pipe 110 and the conduit 120.

Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
