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.

[0023] Please see Figures 1-5This embodiment provides a technical solution: a rotary spraying mechanism for wood furniture production, including a spraying base 1, a rotating cylinder 8 rotatably connected inside the spraying base 1, a protective cover 2 fixedly connected to the upper end of the spraying base 1, a drive chamber 3 fixedly connected to the upper end of the protective cover 2, a controller 13 provided at the front end of the upper surface of the spraying base 1, the input end of the controller 13 being electrically connected to an external power source, and also includes an opening and closing component 4.

[0024] Opening and closing assembly 4: It includes a rotating shaft 43, a rotating cylinder 44, an arc plate 46, and a connecting plate 47. The arc plates 46 are symmetrically arranged inside the protective cover 2. The upper ends of two diagonally adjacent arc plates 46 are fixedly connected to the connecting plate 47. The rotating cylinder 44 is fixedly connected to the center of the upper connecting plate 47. The rotating shaft 43 is fixedly connected to the center of the upper surface of the lower connecting plate 47. The rotating shaft 43 is located inside the rotating cylinder 44 (the central axes of the protective cover 2, the rotating shaft 43, and the rotating cylinder 44 coincide, and the four arc plates 46 are evenly distributed around the central axis of the protective cover 2). The upper ends of the rotating shaft 43 and the rotating cylinder 44 extend into the interior of the drive compartment 3. The opening and closing assembly 4 also includes a drive shaft 42 and an internal gear ring 45. The drive shaft 42 is rotatably connected to the right end inside the drive chamber 3. A drive gear is fixedly connected to the upper end of the outer surface of the drive shaft 42. A driven gear is fixedly connected to the upper end of the outer surface of the rotating shaft 43. The driven gear and the drive gear are meshed. A driven gear is fixedly connected to the upper end of the outer surface of the rotating cylinder 44. A support cylinder is fixedly connected to the upper end of the protective cover 2. An internal gear ring 45 is rotatably connected to the upper end of the inner arc surface of the support cylinder. The internal gear ring 45 and the driven gear are meshed. A transmission gear is fixedly connected to the lower end of the outer surface of the drive shaft 42. The transmission gear and the internal gear ring 45 are meshed. The opening and closing assembly 4 also includes a motor 41. The motor 41 is located at the right end of the upper surface of the drive chamber 3. The lower end of the output shaft of the motor 41 is fixedly connected to the upper end of the drive shaft 42. The input end of the motor 41 is electrically connected to the output end of the controller 13. The controller 13 enables the motor 41 to operate. The output shaft of the motor 41 rotates, which drives the drive shaft 42 to rotate. The drive shaft 42 rotates, which drives the drive gear 1 to rotate, which in turn drives the driven gear 1 to rotate. The driven gear 1 rotates, which drives the rotating shaft 43 to rotate. The rotating shaft 43 rotates, which drives the lower connecting plate 47 to rotate. At the same time, the drive shaft 42 rotates, which drives the transmission gear to rotate, which in turn drives the internal gear ring 45 to rotate. The internal gear ring 45 rotates, which drives the driven gear 2 to rotate, which in turn drives the rotating drum 44 to rotate. The rotating drum 44 rotates, which drives the upper connecting plate 47 to rotate. The two connecting plates 47 rotate in opposite directions (the upper connecting plate 47 rotates clockwise, and the lower connecting plate 47 rotates counterclockwise). The rotation of the connecting plates 47 drives the adjacent arc plates 46 to rotate around the central axis of the protective cover 2. The two horizontally adjacent arc plates 46 cooperate to block the inlet and outlet of the protective cover 2, thereby achieving the closure of the protective cover 2.

[0025] The protective cover 2 has spray pipes 5 installed on both the left and right ends of its inner wall. The upper end of the protective cover 2 has symmetrically distributed supply pipes 6. The end of the supply pipe 6 closest to the center of the protective cover 2 is connected to the upper end of the adjacent spray pipe 5. The end of the supply pipe 6 furthest from the center of the protective cover 2 is connected to the outlet of the external paint tank (the external paint tank is equipped with a pressure pump to pressurize the paint so that it can enter the interior of the supply pipe 6). The end of the spray pipe 5 closest to the center of the protective cover 2 has evenly distributed nozzles 7. Under the action of the internal pressure pump, the paint in the external paint tank enters the interior of the corresponding spray pipe 5 through the supply pipe 6 and is then sprayed out through the evenly distributed nozzles 7.

[0026] The spray gun 1 has an internal cavity 11. The lower end of the rotating cylinder 8 is rotatably connected to the bottom wall of the cavity 11. An internal gear ring 10 is fixedly connected to the middle of the inner wall of the rotating cylinder 8. A motor 12 is installed at the lower end of the spray gun 1. The output shaft of the motor 12 extends into the cavity 11. A drive gear 9 is fixedly connected to the upper end of the output shaft of the motor 12. The drive gear 9 and the internal gear ring 10 are meshed. The input end of the motor 12 is electrically connected to the output end of the controller 13. A frosted plate is installed at the upper end of the rotating cylinder 8 (the frosted plate can be made of high molecular weight polyethylene (PE). High molecular weight polyethylene frosted plates have high hardness, scratch resistance, wear resistance, high and low temperature resistance, long service life, high precision, and the surface is frosted to form a textured surface). The structure effectively increases the friction between the object and the contacting object. The controller 13 enables the motor 12 to operate. The output shaft of the motor 12 rotates, which drives the drive gear 9 to rotate, which in turn drives the internal gear ring 10 to rotate. The rotation of the internal gear ring 10 drives the rotating cylinder 8 to rotate, which in turn drives the wooden furniture to rotate, thereby achieving the rotational painting of the wooden furniture. At the same time, the frosted plate at the upper end of the rotating cylinder 8 increases the friction between the rotating cylinder 8 and the wooden furniture, preventing the wooden furniture from shifting. After the painting is completed, the external pressure pump is stopped, and the controller 13 shuts off the motor 12 and enables the motor 41 to rotate in the opposite direction, so that the arc plate 46 rotates in the opposite direction, thereby opening the protective cover 2. The painted wooden furniture is then taken out through the discharge port of the protective cover 2.

[0027] The working principle of the rotary spray painting mechanism for wooden furniture production provided by this utility model is as follows: During operation, the operator first places the spray painting base 1, protective cover 2, and other mechanisms stably in a horizontal working area. After stable placement, the operator places the wooden furniture to be painted through the feed inlet on the front side of the protective cover 2 onto the upper end of the frosting plate on the upper end of the rotating cylinder 8. Then, the operator uses the controller 13 to activate motor 41. The output shaft of motor 41 rotates, driving the drive shaft 42 to rotate. The drive shaft 42 rotates, driving the drive gear 1 to rotate, thereby driving... The rotation of driven gear 1 drives shaft 43 to rotate, which in turn drives the lower connecting plate 47 to rotate. Simultaneously, the drive shaft 42 rotates, causing the transmission gear to rotate, which in turn drives internal gear ring 45 to rotate. Internal gear ring 45 rotates, which in turn drives driven gear 2 to rotate, which in turn drives rotating cylinder 44 to rotate. Rotating cylinder 44 drives upper connecting plate 47 to rotate. The two connecting plates 47 rotate in opposite directions (the upper connecting plate 47 rotates clockwise, and the lower connecting plate 47 rotates counterclockwise). The rotation of connecting plates 47 drives the adjacent arc-shaped... Plate 46 rotates around the central axis of the protective cover 2. The two adjacent arc-shaped plates 46 cooperate to block the inlet and outlet of the protective cover 2, thereby sealing the protective cover 2. Then, controller 13 shuts off motor 1 41. Under the action of the internal pressure pump, the paint in the external paint tank enters the corresponding spray pipe 5 through the feed pipe 6, and is then sprayed out through the evenly distributed nozzles 7. At the same time, controller 13 starts motor 2 12. The output shaft of motor 2 12 rotates, driving the drive gear 2 9 to rotate, which in turn drives the internal gear ring 2 10 to rotate. The rotation of ring 2 10 drives the rotating cylinder 8 to rotate, which in turn drives the wooden furniture to rotate, thereby achieving the rotational painting of the wooden furniture. At the same time, the frosted plate at the upper end of the rotating cylinder 8 increases the friction between the rotating cylinder 8 and the wooden furniture, preventing the wooden furniture from shifting. After the painting is completed, the personnel stop the operation of the external pressure pump and turn off motor 2 12 through controller 13, and realize the reverse operation of motor 1 41, so that the arc plate 46 rotates in the opposite direction, realizing the opening of the protective cover 2. The personnel take out the painted wooden furniture through the discharge port of the protective cover 2.

[0028] It is worth noting that the controller 13 disclosed in the above embodiments controls the operation of motor 41 and motor 12 using methods commonly used in the prior art.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
