Description
Technical Field
[0001] This utility model belongs to the technical field of powder spraying devices, and in particular relates to an electrostatic powder spraying device for furniture production. Background Technology
[0002] Electrostatic powder coating equipment, a specialized device based on the principle of electrostatic adsorption, primarily functions to uniformly spray dry solid powder coatings onto the surface of workpieces. In the furniture manufacturing industry, electrostatic powder coating technology creates an electrostatic field between the powder coating and the furniture surface, allowing the powder to adhere tightly to the surface, thus forming a coating with excellent properties such as wear resistance, corrosion resistance, and aesthetic appeal. This not only helps improve the appearance of the furniture but also significantly extends its service life.
[0003] However, existing electrostatic powder coating equipment on the market has certain limitations in nozzle design. The nozzles are typically fixed, making it difficult to flexibly adjust them to suit the specific dimensions and shapes of different furniture. In actual production, furniture comes in a wide variety of sizes and shapes, ranging from large wardrobes and sofas to small tables and chairs. Because the spraying range and angle of fixed nozzles are relatively fixed, they cannot adapt to the complex surfaces of different furniture, easily leading to situations where some areas are coated too thickly while others are under-covered. This uneven coating not only affects the appearance and texture of the furniture, causing roughness and unevenness, but may also weaken the protective performance of the coating, reduce the overall coating quality, and ultimately affect the furniture's market competitiveness.
[0004] In response to the problems existing in the above-mentioned electrostatic powder coating equipment, we have developed an electrostatic powder coating equipment for furniture production, aiming to solve the aforementioned technical defects. Utility Model Content
[0005] The purpose of this invention is to provide an electrostatic powder coating device for furniture production. By precisely adjusting the spraying angle of the nozzle from multiple angles in three-dimensional space, it solves the problem that existing powder coating devices cannot be adjusted according to the furniture, thus affecting the coating effect.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is an electrostatic powder coating device for producing furniture, including a coating chamber; a plurality of coating components for coating furniture are evenly arranged on one side of the inner wall of the coating chamber, and a material hanging component for conveying the furniture to be coated is provided at the top of the inner cavity of the coating chamber.
[0008] The spraying assembly includes a sleeve rotatably connected to one side of the inner wall of the spraying chamber. A straight groove is opened at the center of the end of the sleeve located on the outside of the spraying chamber. A first mounting seat and a second mounting seat are fixedly connected to the end of the sleeve located on the outside of the spraying chamber. A rotating seat is rotatably connected between the first mounting seat and the second mounting seat. An installation sleeve is movably sleeved inside the rotating seat. A spray tube is fixedly sleeved inside the installation sleeve. A nozzle is installed at the end of the spray tube located inside the spraying chamber. A connecting plate is fixedly connected to the outside of the installation sleeve. An electric actuator is fixedly connected between the rotating seat and the connecting plate.
[0009] The present invention is further configured such that a toothed ring is fixedly connected to the outside of the sleeve, a mounting bracket is fixedly connected to the outside of the spraying chamber, a rotating motor is fixedly connected to the outside of the mounting bracket, and a drive gear that meshes with the toothed ring is fixedly connected to the output end of the rotating motor.
[0010] The present invention is further configured such that a pitch adjustment motor is fixedly connected to the outside of the second mounting base, a worm gear is fixedly connected to the output end of the pitch adjustment motor, and a worm wheel that meshes with the worm gear is fixedly connected to the outside of the rotating shaft located inside the second mounting base.
[0011] The present invention is further configured such that a protective cover is fixedly connected to one end of the sleeve located inside the spraying chamber.
[0012] The present invention is further configured such that the material hanging assembly includes an electric suspended conveying track fixedly connected to the top of the inner cavity of the spraying chamber, and multiple sliders are installed inside the electric suspended conveying track. The bottom of the slider is rotatably connected to a hanging rod, and the bottom of the hanging rod is fixedly connected to a fixing clamp.
[0013] The present invention is further configured such that a rotating gear is fixedly connected to the outside of the hanging rod, a fixing frame is fixedly connected to the top of the inner cavity of the spraying chamber, and a rack that meshes with the rotating gear is fixedly connected to the outside of the fixing frame.
[0014] The present invention is further configured such that a controller is fixedly connected to the outside of the spraying chamber, and the electric push rod, the rotation motor and the pitch adjustment motor are all electrically connected to the controller.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model uses an electric actuator to extend and retract the connecting plate, causing the mounting sleeve to slide within the rotating seat, thereby adjusting the front and rear position of the spray head. Subsequently, by starting the rotating motor, the gear drives the gear ring, which in turn drives the sleeve to rotate circumferentially. At the same time, the pitch adjustment motor is started, and then through the worm gear and worm wheel transmission, the pitch angle of the rotating seat can be adjusted. Thus, the spraying angle of the spray head can be precisely adjusted in three-dimensional space at multiple angles according to the shape of the furniture, improving the spraying effect.
[0017] 2. This utility model suspends furniture on a hanging rod using a fixing clip. Then, an electric suspension conveyor track drives a slider to move. When the slider passes the fixing frame, the rotating gear meshes with the rack, causing the hanging rod to rotate automatically, which in turn drives the furniture to rotate at a uniform speed, allowing the furniture to be sprayed evenly from all directions.

The distance between the nozzle 209 and the furniture can be adjusted by extending and retracting the electric push rod 211, thereby improving the spraying effect.
[0028] Specifically, a protective cover 219 is fixedly connected to one end of the sleeve 201 located inside the spraying chamber 100. The protective cover 219 can prevent powder leakage and prevent environmental pollution.
[0029] The operation process of this embodiment is as follows: During the process of spraying furniture, electrostatic powder is obtained by connecting an external powder supply system through the spray pipe 208. Then, the connecting plate 210 is driven by the extension and retraction of the electric push rod 211, so that the mounting sleeve 207 slides in the rotating seat 205, thereby adjusting the front and rear position of the spray head 209 to adapt to the spraying needs of furniture of different sizes and improve the spraying effect. Example 2
[0030] Please see Figure 3 Based on the first specific embodiment, a toothed ring 212 is fixedly connected to the outside of the sleeve 201, a mounting bracket 213 is fixedly connected to the outside of the spraying chamber 100, a rotating motor 215 is fixedly connected to the outside of the mounting bracket 213, and a drive gear 214 that meshes with the toothed ring 212 is fixedly connected to the output end of the rotating motor 215.
