Description

Technical Field

[0001] This utility model relates to the technical field of surface coating spraying equipment, and more specifically, to a spraying device for metal surface treatment. Background Technology

[0002] Metal surface coating spraying is a method to protect metals from oxidation and corrosion. This method forms a continuous, complete, and well-bonded protective paint layer on the metal surface, acting as a barrier to inhibit the intrusion of corrosive media. This effectively isolates water, oxygen, electrons, stray ions, and other substances from penetrating, greatly slowing down or preventing coating corrosion of the metal.

[0003] For example, Chinese patent CN221514936U discloses a surface coating spraying device. This device places a metal tube on the top surface of a rotating shell between two clamping blocks. Through a drive assembly, two racks slide and move closer to each other in a sliding groove. The two racks then drive the two clamping blocks to slide and move closer to each other in the sliding groove, thus fixing the lower end of the metal tube. After one side of the metal tube is coated, the operator rotates a worm gear. Under the meshing action, the worm gear drives a worm wheel to rotate in the power chamber. The worm wheel drives the rotating shell to rotate, and then the rotating shell can drive the metal tube to rotate through the two clamping blocks. When the metal tube rotates to the appropriate position, the worm gear is stopped. This ensures that the metal tube does not need to be fixed while spraying, allowing it to rotate during spraying, facilitating the spraying process and speeding up the work.

[0004] The aforementioned patent has the following problems:

[0005] The patent has the following drawbacks when in use: the contact surface between the clamping block and the metal tube cannot be effectively treated, and secondary processing is required after the spraying operation. Secondly, the paint in the patent is easy to adhere to the rotating shell and the clamping block after spraying. If the paint layer is thick or unevenly distributed, it may also cause the metal workpiece to be placed unevenly, thereby affecting the spraying effect and product quality. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a spraying device for metal surface treatment. It can achieve spraying operation by optimizing the rotating shell design and using a magnetic chuck, effectively avoiding direct contact between the metal tube and the clamping block in the traditional clamping method. This eliminates the need for secondary processing of the contact surface, saving time and costs. By setting up a coating cleaning mechanism, the coating layer adhering to the magnetic chuck can be quickly cleaned after the batch of metal workpieces is sprayed, ensuring the magnetic chuck's adsorption effect on the metal workpieces.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A metal surface treatment spraying device includes a worktable, a working chamber at the upper end of the worktable, and a positioning spraying mechanism on the worktable. The positioning spraying mechanism includes a positioning box at the upper end of the worktable, a drive motor at the inner end of the positioning box, a rotating shaft fixedly connected to the output end of the drive motor, and a magnetic turntable fixedly connected to the end of the rotating shaft away from the drive motor. A metal workpiece is placed on the magnetic turntable. A sliding groove is formed on the side wall of the working chamber. An electric push rod is arranged on the worktable and located on the side of the working chamber. A paint gun is fixedly connected to the output end of the electric push rod and is positioned in the sliding groove. The spray gun is slidably connected to the inside of the positioning box. A transmission hose is connected to the tail end of the spray gun. A coating cleaning mechanism is provided on the positioning box. The coating cleaning mechanism includes an extension plate set on the side wall of the positioning box. A pair of upright plates are fixedly connected to the upper end of the extension plate. Each pair of upright plates is provided with a rotating hole. A drive motor is set on the side wall of one of the upright plates. A driven shaft is fixedly connected to the output end of the drive motor. The driven shaft passes through the pair of rotating holes. A driven plate is fixedly connected to the outer end of the driven shaft. An assembly groove is opened on the driven plate. A connecting block is movably connected in the assembly groove. A brush bristle is fixedly connected to the lower end of the connecting block.

[0011] Furthermore, the assembly groove is a "T" shaped groove, and the shape of the connecting block matches it.

[0012] Furthermore, the bristles are hard bristles, and the end of the bristles away from the connecting block is in contact with the surface of the magnetic turntable.

[0013] Furthermore, the drive motor is equipped with control parameters so that it can rotate to a preset angle when it receives a control signal. The drive motor alternates between two states: 270° forward rotation and 270° reverse rotation. In one state, the drive motor drives the driven shaft and driven plate to rotate until the driven plate is parallel to the magnetic turntable. In the other state, the drive motor drives the driven shaft and driven plate to rotate until the driven plate is parallel to the vertical plate.

[0014] Furthermore, when the driven plate is adjusted to be parallel to the magnetic turntable, the end of the driven plate away from the driven shaft coincides with the center of the magnetic turntable. Beneficial effects

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0027] Please see Figure 1-4A metal surface treatment spraying device includes a workbench 1, a working chamber 2 at the upper end of the workbench 1, and a positioning spraying mechanism on the workbench 1. The positioning spraying mechanism includes a positioning box 3 at the upper end of the workbench 1, a drive motor 4 at the inner end of the positioning box 3, the speed of the drive motor 4 being controllable by a program, a rotating shaft 5 fixedly connected to the output end of the drive motor 4, and a magnetic turntable 6 fixedly connected to the end of the rotating shaft 5 away from the drive motor 4. Metal workpieces are placed on the magnetic turntable 6, and the magnetic force of the magnetic turntable 6 is set to parameters that can stably attract metal workpieces placed on its surface, and that allow an adult to easily remove the metal workpieces. A sliding groove 201 is provided on the side wall of the working chamber 2, and an electric push rod 9 is provided on the workbench 1 and located on the side of the working chamber 2. A paint gun 7 is fixedly connected to the output end of the electric push rod 9. The spray gun 7 is placed in and slidably connected to the slide 201. The nozzle of the spray gun 7 is set in the working chamber 2. The electric push rod 9 can drive the spray gun 7 to slide up and down along the slide 201 to process metal workpieces of different heights and specifications. During use, some paint will inevitably flow along the metal workpiece to the surface of the magnetic turntable 6. The paint adhering to the magnetic turntable 6 will form a layer of obstacles, which will hinder the penetration of magnetic lines of force, thereby reducing the attraction force of the magnetic turntable 6 on the metal workpiece. At the same time, if a metal workpiece larger than the size being processed is placed on the magnetic turntable 6, the lower surface of the metal workpiece will come into contact with the unevenly distributed and different thicknesses of the paint layer. At this time, the large-sized metal workpiece on the magnetic turntable 6 is prone to imbalance during rotation, which will affect the spraying effect. The tail end of the spray gun 7 is connected to the transmission hose 8, and the positioning box 3 is equipped with a coating cleaning mechanism.

[0028] The coating cleaning mechanism includes an extension plate 10 mounted on the side wall of the positioning box 3. A pair of upright plates 11 are fixedly connected to the upper end of the extension plate 10. Each upright plate 11 has a rotating hole. A drive motor 12 is mounted on the side wall of one of the upright plates 11. A driven shaft 13 is fixedly connected to the output end of the drive motor 12. The driven shaft 13 passes through the pair of rotating holes. A driven plate 14 is fixedly connected to the outer end of the driven shaft 13. An assembly groove is provided on the driven plate 14, and a connecting block 15 is movably connected within the assembly groove. The assembly groove is a "T"-shaped groove, and the shape of the connecting block 15 matches it. Brush bristles 16 are fixedly connected to the lower end of the connecting block 15. The brush bristles 16 are hard bristles, and the end of the brush bristles 16 furthest from the connecting block 15 is magnetically attracted. The surfaces of the turntable 6 are closely fitted to ensure effective cleaning of the coating layer adhering to the surface of the magnetic turntable 6. After the bristles 16 wear down over a period of use, they can be quickly replaced. The drive motor 12 is equipped with control parameters so that it can rotate to a preset angle upon receiving a control signal. The drive motor 12 alternates between two states: forward rotation of 270° and reverse rotation of 270°. In one state, the drive motor 12 drives the driven shaft 13 and the driven plate 14 to rotate until the driven plate 14 is parallel to the magnetic turntable 6. When the driven plate 14 is adjusted to be parallel to the magnetic turntable 6, the end of the driven plate 14 furthest from the driven shaft 13 coincides with the center of the magnetic turntable 6. Figure 1 As shown, after removing the coated metal workpiece, the driven plate 14 is adjusted to this state, and the drive motor 4 is restarted to drive the magnetic turntable 6 to rotate at high speed. This can clean the coating layer adhering to the surface of the magnetic turntable 6. Another state is that the drive motor 12 drives the driven shaft 13 and the driven plate 14 to rotate until the driven plate 14 is parallel to the vertical plate 11. Figure 3 As shown, this state is the state of the metal workpiece during the spraying process.

[0029] When processing metal workpieces using this device, the metal workpiece is first placed on the magnetic turntable 6. Then, the drive motor 4 is started, causing the magnetic turntable 6 and the metal workpiece to rotate at a low speed. Next, the electric push rod 9 drives the paint gun 7 to slide up and down, spraying the surface of the metal workpiece. After the batch of metal workpieces is processed, the drive motor 4 is paused, and the metal workpiece is removed. Then, the drive motor 12 is started and rotated 270°, causing the driven shaft 13 and driven plate 14 to rotate until the driven plate 14 is parallel to the magnetic turntable 6. At this point, the brush bristles 16 are in contact with the surface of the magnetic turntable 6. The magnetic turntable 6 is restarted and rotated at high speed. As it rotates, the brush 16 cleans the coating layer on the surface. Compared with the prior art, this utility model optimizes the design of the rotating shell and uses the magnetic turntable 6 for spraying, which effectively avoids the direct contact between the metal tube and the clamping block in the traditional clamping method. This eliminates the need for secondary processing of the contact surface, saving time and costs. At the same time, the coating cleaning mechanism can quickly clean the coating layer adhering to the magnetic turntable 6 after the batch of metal workpieces has been sprayed, ensuring the adsorption effect of the magnetic turntable 6 on the metal workpieces.

[0030] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
