Description

Technical Field

[0001] This utility model relates to the field of metal surface powder coating, and in particular to an environmentally friendly electrostatic powder coating device for metal surfaces. Background Technology

[0002] Electrostatic powder coating is a commonly used metal surface coating technology. It uses electrostatic force to spray powdered coating onto the metal surface, and then heats it to melt and solidify it, forming a strong and uniform coating. This technology is widely used in the surface treatment of various metal products, especially in the fields of home appliances, automobiles, construction and furniture.

[0003] Most existing environmentally friendly electrostatic powder coating equipment for metal surfaces requires manual operation by holding the spray nozzle. This method is not only labor-intensive but also requires high technical skills from the operator, which can easily lead to missed spraying or inconsistent coating thickness, thus affecting the efficiency and quality of metal surface powder coating.

[0004] Therefore, it is necessary to provide an environmentally friendly electrostatic powder coating device for metal surfaces to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes an environmentally friendly electrostatic powder coating device for metal surfaces.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A base is included, with a mounting frame fixedly connected between the two sides of the base. A mounting groove is formed at the bottom of the inner wall of the mounting frame. A driving assembly is provided on one side of the mounting frame. One end of the driving assembly extends into the interior of the mounting groove and is equipped with a reciprocating screw. A moving plate is threadedly connected to the outer surface of the reciprocating screw. A swing assembly is provided at the top of the moving plate. A concentrator is provided at the bottom of the swing assembly. Several nozzles are fixedly connected to the outside of the concentrator. A flexible hose is fixedly connected to one end of the concentrator. A guide bucket is fixedly connected to one end of the flexible hose. A pushing assembly is provided at the top of the base. A material box is fixedly connected to the top of the base. An air compressor is installed on the top of the material box. A placement assembly is provided at the top of the base.

[0007] By setting up a drive component, the reciprocating screw can be rotated, causing the moving plate to move the central tube via the swing component. The central tube then moves several nozzles. At this time, the air compressor is started, so that the powder in the material box enters the guide hopper and is transported into the central tube, allowing the nozzles to spray the powder onto the metal placed in the component. At the same time, the push component allows the swing component to swing the central tube left and right, so that the several nozzles can spray the powder onto the metal more evenly.

[0008] The drive assembly includes a motor mounted on one side of the mounting bracket via a bracket, and a pulley is sleeved on the outside of the motor output end.

[0009] By starting the motor, its output end drives the reciprocating screw to rotate, which in turn causes the moving plate to move the swing assembly and the central tube.

[0010] The swing assembly includes two grooves formed at the bottom of the movable plate, and a sliding rod is fixedly connected inside each of the two grooves.

[0011] Both slide bars are slidably connected to the outside of each of the slide bars, and a spring is fixedly connected to one side of one of the slide bars.

[0012] By setting a spring, when the pushing component fails to push one of the mounting bars, the mounting bar is reset, thereby realizing the reciprocating swing of the central tube.

[0013] The pushing assembly includes two mounting plates fixedly connected to the top of the base, and a mounting rod is rotatably connected between opposite sides of the two mounting plates.

[0014] The mounting rod is externally fixedly connected with a protruding strip, and one end of the mounting rod extends through to the outside of one of the mounting plates and is fitted with a pulley.

[0015] By setting a second pulley, the motor can drive the first pulley to rotate, and the first pulley can use a belt to drive the second pulley and the mounting rod to rotate synchronously, thereby causing the mounting rod to drive the convex strip to rotate and push one of the mounting strips to move.

[0016] The placement assembly includes a placement frame fixedly connected to the top of the base. Threaded rods are threaded through both sides of the placement frame, and clamps are fixedly connected to the opposite sides of the two threaded rods.

[0017] By rotating the threaded rod, the clamping plate can be moved, thereby limiting the metal inside the placement frame.

[0018] The two sides of the clamp are slidably connected to the two sides inside the placement frame.

[0019] Compared with the prior art, the beneficial effects of this utility model include:

[0020] 1. By using a combination of drive components, reciprocating screws, moving plates, swing components, central pipes, nozzles, hoses, guide buckets, push components, material bins, and air compressors, automatic all-around powder coating of metal surfaces can be achieved. This ensures that the coating is evenly sprayed onto the metal surface, eliminating the need for manual powder coating, saving time and labor. At the same time, it solves the common problems of missed spraying or large differences in powder thickness in manual operation, improving the efficiency and effect of powder coating of metal surfaces.

[0021] 2. By setting up placement components, metals of different widths can be clamped and limited to ensure that the metal workpieces are stably fixed during the spraying process, avoiding the impact of workpiece displacement or swaying on the powder coating effect, thus improving the practicality of the environmentally friendly electrostatic powder coating device for metal surfaces.

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] According to one embodiment of the present invention, in conjunction with Figure 1-4As shown. An environmentally friendly electrostatic powder coating device for metal surfaces includes a base 1, a mounting frame 2 fixedly connected between the two sides of the base 1, a mounting groove 3 formed at the bottom of the inner wall of the mounting frame 2, a drive assembly provided on one side of the mounting frame 2, one end of the drive assembly penetrating into the interior of the mounting groove 3 and provided with a reciprocating screw 4, a moving plate 5 threadedly connected to the outer surface of the reciprocating screw 4, a swing assembly provided on the top of the moving plate 5, a central pipe 6 provided at the bottom of the swing assembly, several nozzles 7 fixedly connected to the outside of the central pipe 6, a hose 8 fixedly connected to one end of the central pipe 6, a guide bucket 9 fixedly connected to one end of the hose 8, a pushing assembly provided on the top of the base 1, a material box 24 fixedly connected to the top of the base 1, an air compressor 10 installed on the top of the material box 24, a placement assembly provided on the top of the base 1, and the top of the moving plate 5 slidingly connected to the top of the inner wall of the mounting groove 3. Next, the movable plate 5 is convex in shape and its bottom extends to the lower part of the mounting groove 3. The bottom ends of several nozzles 7 are located directly below the central tube 6. The output end of the air compressor 10 passes through the interior of the material box 24, and one end of the hose 8 passes through the interior of the material box 24. The outside of the guide bucket 9 is fixedly connected to the bottom of the inner wall of the material box 24. By setting a drive component, the reciprocating screw 4 can be driven to rotate, so that the movable plate 5 drives the central tube 6 to move using the swing component, so that the central tube 6 drives several nozzles 7 to move. At this time, the air compressor 10 is started, so that the powder in the material box 24 enters the guide bucket 9 and is transported to the central tube 6, so that the nozzles 7 can spray the powder onto the metal in the placement component. At the same time, by using the push component, the swing component can drive the central tube 6 to swing left and right, so that several nozzles 7 can spray the powder onto the metal more evenly.

[0030] The drive assembly includes a motor 11 mounted on one side of the mounting bracket 2 via a bracket. A pulley 12 is sleeved on the outside of the output end of the motor 11. The output end of the motor 11 extends into the interior of the mounting groove 3, and one end of the reciprocating screw 4 is fixedly connected to the output end of the motor 11. By starting the motor 11, its output end drives the reciprocating screw 4 to rotate, thereby enabling the moving plate 5 to drive the swing assembly and the central tube 6 to move.

[0031] The swing assembly includes two slide grooves 13 formed at the bottom of the movable plate 5. A slide rod 14 is fixedly connected inside each of the two slide grooves 13. The two slide grooves 13 are symmetrical about the center of the movable plate 5. A mounting strip 15 is slidably connected to the outside of each of the two slide rods 14. A spring 16 is fixedly connected to one side of one of the mounting strips 15. One end of the spring 16 is slidably connected to one side of the inner wall of the slide groove 13. The central tube 6 is fixedly connected between the bottoms of the two mounting strips 15. By setting the spring 16, when the pushing assembly does not push one of the mounting strips 15, the mounting strip 15 is reset, thereby realizing the reciprocating swing of the central tube 6.

[0032] The pushing assembly includes two mounting plates 17 fixedly connected to the top of the base 1. A mounting rod 18 is rotatably connected between opposite sides of the two mounting plates 17. A protrusion 19 is fixedly connected to the outside of the mounting rod 18. One end of the mounting rod 18 extends through the outside of one of the mounting plates 17 and is fitted with a pulley 20. The length of the protrusion 19 is the same as the length of the reciprocating screw 4, and the protrusion 19 is located on one side of one of the mounting bars 15. Both sides of the protrusion 19 are arc-shaped. The pulley 12 and the pulley 20 are connected by belt drive. By setting the pulley 20, the motor 11 can drive the pulley 12 to rotate. The pulley 12 uses the belt to drive the pulley 20 and the mounting rod 18 to rotate synchronously, thereby causing the mounting rod 18 to drive the protrusion 19 to rotate and push one of the mounting bars 15 to move.

[0033] The placement assembly includes a placement frame 21 fixedly connected to the top of the base 1. Threaded rods 22 are threaded through both sides of the placement frame 21. Clamping plates 23 are fixedly connected to the opposite sides of the two threaded rods 22. The clamping plates 23 are slidably connected to the two sides inside the placement frame 21. The clamping plates 23 are made of rubber. One end of the threaded rod 22 is threaded through the inside of the placement frame 21. By rotating the threaded rod 22, the clamping plates 23 can be moved, thereby limiting and clamping the metal inside the placement frame 21.

[0034] In this embodiment, when it is necessary to perform powder coating on the metal surface, the metal is first clamped and limited. By placing the metal inside the placement frame 21, the two threaded rods 22 are rotated so that the two threaded rods 22 drive the two clamping plates 23 to move until the clamping plates 23 abut against the two sides of the metal. At this time, the threaded rods 22 are stopped, and the metal is clamped and limited.

[0035] Then, the motor 11 is started, and its output end drives the reciprocating screw 4 to rotate. At this time, the moving plate 5 on the reciprocating screw 4 will move with the rotation of the reciprocating screw 4, thereby driving the two mounting strips 15 and the central pipe 6 to move, so that several nozzles 7 move above the metal. At the same time, the air compressor 10 is started to generate high-pressure air. The high-pressure air enters the material box 24 and pushes the powdered paint into the guide hopper 9, and then from the guide hopper 9 into the inside of the hose 8. At this time, the moving nozzles 7 will spray the powdered paint onto the metal surface.

[0036] Furthermore, motor 11 drives pulley 12, which in turn drives pulley 20 via a belt. Pulley 20 then drives mounting rod 18 to rotate, causing mounting rod 18 to rotate convex strip 19 until convex strip 19 abuts against one side of one of mounting strips 15. At this point, convex strip 19 pushes one of the mounting strips 15, causing it to move the other mounting strip 15 and the central tube 6 synchronously and compress spring 16, thereby moving several nozzles 7. Afterward, when convex strip 19 no longer abuts against one of the mounting strips 15, the elastic force of spring 16 gradually moves the two mounting strips 15 and the central tube 6 back to their original positions. This process is repeated, causing several nozzles 7 to swing left and right continuously, allowing the nozzles 7 to evenly spray powder coating onto the metal surface. After the powder coating work is completed, reverse threaded rod 22 so that the two clamps 23 do not abut against the sides of the metal. At this point, the metal can be removed and heated to melt the coating on its surface.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
