Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, specifically to a metal steel outer surface anti-corrosion spraying device. Background Technology

[0002] As a key component in the mechanical field, the surface anti-corrosion treatment of metal rods directly affects the service life of the components and engineering safety. Conventional single-axis spraying devices typically operate by using a fixed clamp to hold a single rod and drive it to rotate around its axis, completing the spiral spraying operation through a linearly moving spray gun. While this technology can ensure uniform coating coverage on the rod's curved surface, its limited single-station design results in a low throughput per unit time, a significant efficiency disadvantage, especially in mass production scenarios.

[0003] To improve operational efficiency, some improved equipment adopts a multi-axis synchronous spraying structure, using an array-type clamping mechanism to simultaneously clamp multiple rods. However, while this solution can increase the number of rods that can be sprayed simultaneously, in practical applications, the spraying machine often can only spray the curved surfaces of multiple rods. For rods with protrusions or depressions, especially for rods with vertical surfaces or concealed sloping surfaces, this array-type spraying device often struggles to accurately and completely spray these surfaces, resulting in spraying dead zones. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0005] A metal steel outer surface anti-corrosion spraying device includes a fixed spraying machine, with multiple metal rods arranged in a circumferential array outside the fixed spraying machine. The metal rods are connected to a planetary gear set, which drives the multiple metal rods to synchronously revolve and rotate around the fixed spraying machine.

[0006] The fixed spraying machine has multiple linear nozzles arranged in a linear fashion. These nozzles spray the curved surface of the metal rod with anti-corrosion coating in a direction perpendicular to the axis of the metal rod.

[0007] The fixed spraying machine is equipped with a transverse mechanism, on which a mobile spraying machine is mounted. The transverse mechanism drives the mobile spraying machine to move linearly along the axis of the metal rod, and the nozzle of the mobile spraying machine sprays the vertical surface of the metal rod at a spray angle inclined to the axis of the metal rod.

[0008] As a preferred embodiment of the present invention, the planetary gear set includes a drive structure, an outer gear sleeve, a sun gear disposed in the outer gear sleeve, and a plurality of planet gears meshing with the edge of the sun gear. The drive structure is disposed in the base shell, the outer gear sleeve is fixedly connected to the base shell, the planet gears are meshed with the inner side of the outer gear sleeve, a metal rod is connected to one side of the planet gear, and a sleeve rod is coaxially rotatably connected to the other side. The sleeve rod is connected to the ring sleeve through a connecting rod.

[0009] A fixed spraying machine is connected to one side of the sun gear, and a fixed shaft is connected to the other side. The fixed shaft extends outward and is fixedly installed on the base shell. A ring sleeve is coaxially sleeved outside the fixed shaft, and the ring sleeve is connected to the drive structure.

[0010] As a preferred embodiment of this utility model, the drive structure includes a gear disk coaxially and fixedly connected to the ring sleeve, the gear disk being rotatably connected to a fixed shaft, a drive gear meshing with the gear disk, an output motor coaxially connected to the drive gear, and the output motor being fixedly installed inside the base housing.

[0011] As a preferred embodiment of this utility model, the transverse movement mechanism includes a driven gear, a synchronizing screw, and a limiting rod. The driven gear is meshed with the gear plate and is axially rotatably mounted on the base shell through a connecting piece. The synchronizing screw is coaxially fixedly connected to one side of the two driven gears. A threaded collar is connected to the synchronizing screw by thread engagement. A limiting rod is provided on the outside of the synchronizing screw. The end of the limiting rod is fixedly connected to the base shell. A limiting ring is slidably sleeved on the limiting rod. Both the limiting ring and the threaded collar are fixedly connected to the mobile spraying machine.

[0012] As a preferred embodiment of this utility model, the mobile spraying machine includes a spraying machine body and an oscillating nozzle. The oscillating nozzle is connected to the spraying machine body through a guide pipe. The spraying machine body is fixedly connected to a limiting ring and a threaded collar. A strip-shaped groove is provided at the bottom of the threaded collar. The opening direction of the strip-shaped groove is parallel to the axial direction of the synchronous screw. A U-shaped bracket is provided below the strip-shaped groove. The horizontal section of the U-shaped bracket is perpendicular to the strip-shaped groove, and an insertion gap is provided between the horizontal section of the U-shaped bracket and the strip-shaped groove.

[0013] A swing arm is rotatably connected to the U-shaped bracket. One end of the swing arm extends downward and is connected to a swing nozzle, while the other end extends upward and slides through the insertion gap into the strip groove.

[0014] An L-shaped guide rod is fixedly installed on the top of the outer toothed sleeve, with one end of the L-shaped guide rod facing the insertion gap.

[0015] As a preferred embodiment of this utility model, the base shell is slidably disposed on the substrate along the axial direction of the synchronizing screw, and both the synchronizing screw and the limiting optical rod are capable of axial extension and retraction.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This invention utilizes the coordinated operation of a fixed and a mobile sprayer, along with a directional mechanism employing both vertical and inclined nozzles. As multiple rods rotate and revolve synchronously driven by a planetary gear set, the vertical nozzles of the fixed sprayer and the inclined nozzles of the mobile sprayer form a composite spraying field, simultaneously covering the arc surfaces and vertical surfaces of the rods, thereby increasing the overall spraying range. Furthermore, after the mobile sprayer reaches its linear position, the L-shaped guide rod and the swing arm automatically switch the orientation of the swing nozzles, matching the reciprocating sliding motion of the mobile sprayer to precisely cover the vertical surfaces on both sides of the rods, further expanding the spraying range and eliminating spraying dead zones.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 3 As shown, this utility model provides a metal steel outer surface anti-corrosion spraying device, including a fixed spraying machine 1. Multiple metal rods 2 are arranged circumferentially outside the fixed spraying machine 1. The metal rods 2 are connected to a planetary gear set 3, which drives the multiple metal rods 2 to synchronously revolve and rotate outside the fixed spraying machine 1. Multiple linear nozzles 4 are linearly arranged on the fixed spraying machine 1 to cover the length direction of the rods. The multiple linear nozzles 4 perform anti-corrosion spraying on the arc-shaped surface of the metal rods 2 in a direction perpendicular to the axis of the metal rods 2.

[0026] Among them, such as Figure 1 and Figure 2 As shown, the planetary gear set 3 includes a drive structure 8, an outer gear sleeve 9, a sun gear 10 disposed in the outer gear sleeve 9, and a plurality of planet gears 11 meshing with the edge of the sun gear 10. The drive structure 8 is disposed in the base shell 12. The outer gear sleeve 9 is fixedly connected to the base shell 12. The planet gears 11 are meshed with the inner side of the outer gear sleeve 9. A metal rod 2 is connected to one side of the planet gear 11, and a sleeve rod 13 is coaxially rotatably connected to the other side. The sleeve rod 13 is connected to the ring sleeve 15 through a connecting rod 14.

[0027] like Figure 1 As shown, a fixed sprayer 1 is connected to one side of the sun gear 10, and a fixed shaft 16 is connected to the other side. The fixed shaft 16 extends outward and is fixedly installed on the base shell 12. The ring sleeve 15 is coaxially sleeved outside the fixed shaft 16, and the ring sleeve 15 is connected to the drive structure 8.

[0028] When the drive structure 8 drives the planetary gear set 3 to rotate, the planetary gear 11 revolves around the sun gear 10 to change its own position, and at the same time rotates to change the orientation of the arc surface, so that multiple straight nozzles 4 can spray the arc surface of the rod at various positions.

[0029] like Figure 1As shown, a horizontal movement mechanism 6 is externally mounted on the fixed spraying machine 1, and a mobile spraying machine 7 is mounted on the horizontal movement mechanism 6. The horizontal movement mechanism 6 drives the mobile spraying machine 7 to move linearly along the axis of the metal rod 2, and the nozzle of the mobile spraying machine 7 sprays the vertical surface of the metal rod 2 at a spray angle inclined to the axis of the metal rod 2. The inclined nozzle on the mobile spraying machine 7 sprays the metal rod 2 at an angle inclined to the axis of the metal rod 2, thereby ensuring accurate spraying of the vertical surface of the metal rod 2 during the movement of the mobile spraying machine 7. Furthermore, by adjusting the moving speed or the reciprocating movement of the mobile spraying machine 7, it is ensured that the vertical surface of the continuously rotating rod is fully sprayed.

[0030] Among them, such as Figure 2 As shown, the drive structure 8 includes a geared disc 17 coaxially fixedly connected to the ring sleeve 15. The geared disc 17 is coaxially rotatably connected to the fixed shaft 16. The geared disc 17 is meshed with a drive gear 18, and the drive gear 18 is coaxially connected to an output motor 19, which is fixedly installed inside the base housing 12. The output motor 19 drives the drive gear 18 to rotate, which in turn drives the geared disc 17 to rotate. The geared disc 17 drives the ring sleeve 15 to rotate, thereby driving multiple planetary gears 11 to rotate synchronously on their own axis and revolve around the sun via the connecting rod 14 and the sleeve rod 13. The output motor 19 drives two geared discs 17 to rotate in the same direction. Furthermore, the sun gear 10 is fixedly mounted on the base housing 12 via the fixed shaft 16, which improves the stability of the sun gear 10 and the overall structure.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the transverse mechanism 6 includes a driven gear 20, a synchronous screw 21, and a limiting rod 22. The driven gear 20 is meshed with the gear disk 17 and is axially rotatably mounted on the base shell 12 through a connecting piece. The synchronous screw 21 is coaxially fixedly connected to one side of the two driven gears 20. A threaded collar 23 is connected to the synchronous screw 21 by thread engagement. A limiting rod 22 is provided on the outer side of the synchronous screw 21. The end of the limiting rod 22 is fixedly connected to the base shell 12. A limiting ring 24 is slidably sleeved on the limiting rod 22. Both the limiting ring 24 and the threaded collar 23 are fixedly connected to the mobile spraying machine 7.

[0032] like Figure 3As shown, the mobile spraying machine 7 includes a spraying machine body 25 and an oscillating nozzle 26. The oscillating nozzle 26 is connected to the spraying machine body 25 through a guide pipe. The spraying machine body 25 is fixedly connected to a limiting ring 24 and a threaded collar 23. A strip-shaped groove 27 is provided at the bottom of the threaded collar 23. The opening direction of the strip-shaped groove 27 is parallel to the axial direction of the synchronous screw 21. A U-shaped bracket 28 is provided below the strip-shaped groove 27. The horizontal section of the U-shaped bracket 28 is perpendicular to the strip-shaped groove 27, and an insertion gap is provided between the horizontal section of the U-shaped bracket 28 and the strip-shaped groove 27.

[0033] like Figure 3 As shown, a swing rod 29 is rotatably connected to the U-shaped bracket 28. One end of the swing rod 29 extends downward and is connected to the swing nozzle 26, while the other end extends upward and slides through the insertion gap into the strip groove 27. An L-shaped guide rod 5 is fixedly installed on the top of the outer toothed sleeve 9, with one end of the L-shaped guide rod 5 facing the insertion gap.

[0034] When the gear 17 rotates, it synchronously drives the driven gear 20 to rotate, which in turn drives the synchronous screw 21 to rotate. The threaded collar 23 on the synchronous screw 21 forms a limiting connection with the limiting rod 22 through the spraying machine body 25 and the limiting ring 24. Therefore, when the driven gear 20 rotates, the threaded collar 23 can drive the spraying machine body 25 to move linearly, thereby enabling the oscillating nozzle 26 to perform moving spraying.

[0035] Furthermore, the swing nozzle 26 is mounted on the swing arm 29, which is slidably positioned within the strip groove 27 and rotatably connected to the horizontal end of the U-shaped bracket (a conduit can be arranged within the swing arm 29, the entire conduit being embedded inside the threaded collar 23 and connected to the spraying machine body 25). Therefore, when the top of the swing arm 29 is squeezed, causing it to slide within the strip groove, its bottom end (i.e., the swing nozzle 26) can be driven to swing, thus changing its orientation. An L-shaped guide rod 5 is fixedly mounted on the outer toothed sleeve 9, allowing the spraying machine body 25 to be aligned with the insertion gap and inserted when it moves to this position, thereby pushing the swing arm 29 to move and changing the orientation of the swing nozzle 26. This enables the mobile spraying machine 7 to automatically change the nozzle position under linkage control, and then, in conjunction with the reverse sliding of the spraying machine body 25, spraying is performed on the other side of the vertical surface.

[0036] Furthermore, such as Figure 1As shown, to facilitate the loading and unloading of the rods, the base shell 12 is slidably mounted on the substrate along the axial direction of the synchronous screw 21. Specifically, one side of the base shell 12 is mounted on the base surface via a ground rail. Both the synchronous screw 21 and the limiting rod 22 are axially extendable, allowing the base shell 12 on one side to drive the planetary gear set 3 and other structures to slide outwards, increasing the spacing and facilitating the loading and unloading of the rods. The extension and retraction of the synchronous screw 21 and the limiting rod 22 can be achieved at the position covered by the L-shaped guide rod 5 (i.e., the position where the mobile spraying machine 7 will not move). A sleeve is installed at this position to achieve the extension and retraction of the synchronous screw 21 and the limiting rod 22. The sleeve uses circumferential limiting to avoid restricting the axial rotation of the synchronous screw 21.

[0037] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
