[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figure 1 The utility model provides a technical solution: a wooden furniture spray painting device.

[0024] Among them, a base 2 is arranged at the bottom center of the conveyor belt 1, an outer ring 3 is arranged at the center of the base 2, an inner ring 4 is installed on the inner side of the outer ring 3, a driven gear 5 is fixedly connected to the inner side of the inner ring 4, a motor 7 is arranged on one side of the base 2, a driving gear 6 is arranged on the front side of the motor 7, and a nozzle 9 is arranged near the inner side of the top of the inner ring 4.

[0025] In this embodiment, the base 2 is arranged at the center of the conveyor belt 1, and an inner ring 4 and an outer ring 3 are arranged above the base 2, both of which are circular and surround the conveyor belt 1, and the outer ring 3 and the inner ring 4 are concentric circles, and the center of the circle is located on the conveyor belt 1, wherein the outer ring 3 is fixed on the base 2 and will not move, and the thickness of the outer ring 3 is greater than that of the inner ring 4, and a groove is opened in the middle position of the outer ring 3, and the inner ring 4 is arranged in the groove, and the inner ring 4 is pressed by the driving gear 6 at the bottom engaging the driven gear 5 on the inner side of the inner ring 4, and the driving gear 6 is driven by the motor 7, and the motor 7 drives the driving gear 6 to rotate, and the driving gear 6 is driven by the motor 7. The meshing of the wheel 6 and the driven gear 5 drives the inner ring 4 to rotate, and the nozzle 9 on the inner ring 4 rotates accordingly. When the horizontal position of the nozzle 9 is close to being parallel to the conveyor belt 1, the motor 7 rotates in the opposite direction, causing the inner ring 4 to rotate in the opposite direction, and the nozzle 9 returns to move to the other side. Then, until the horizontal position of the nozzle 9 on the other side of the conveyor belt 1 is close to being parallel to the conveyor belt 1, the motor 7 switches the rotation direction again, and the nozzle 9 returns. This cycle is repeated, and the conveyor belt 1 slowly drives the furniture product forward, and the inner ring 4 drives the nozzle 9 to swing back and forth, so that paint can be sprayed on every part of the furniture.

[0026] A roller 8 is arranged on the inner side of the outer ring 3 near the bottom, and the outer surface of the inner ring 4 is in close contact with the surface of the roller 8 .

[0027] In this embodiment, rollers 8 are provided on both sides of the inner ring 4, with four rollers 8 on each side. The rollers 8 lift up the inner ring 4 and cooperate with the driving gear 6 to engage the driven gear 5 to stabilize the position of the inner ring 4 on the outer ring 3. When the inner ring 4 rotates, the sliding friction between the inner ring 4 and the outer ring 3 is converted into rolling friction, which greatly reduces the friction between the two and makes the rotation of the inner ring 4 smoother.

[0028] A storage box 12 is provided on one side of the conveyor belt 1 , a hose 10 is provided through the center of the connecting block 11 , one end of the hose 10 is connected to the nozzle 9 , and the other end of the hose 10 is connected to the storage box 12 .

[0029] In this embodiment, liquid paint is stored in the storage box 12, and the spray head 9 draws the paint in the storage box 12 through the hose 10, converts it into mist through the spray head 9 and sprays it on the surface of the furniture to achieve painting.

[0030] Among them, a connecting block 11 is fixedly connected to one side of the outer ring 3, and a winding pile 13 is arranged on the top of the storage box 12. The surface of the winding pile 13 is wound with a hose 10, and the winding pile 13 can rotate.

[0031] In this embodiment, the winding pile 13 realizes the winding and releasing of the hose 10 by rotation. The hose 10 connects the nozzle 9 and the storage box 12, and passes through the hole in the middle of the connecting block 11. When the inner ring 4 drives the nozzle 9 to move, the distance between the nozzle 9 and the storage box 12 will change with the position of the nozzle 9. This change is regular because the inner ring 4 rotates regularly. The winding pile 13 cooperates with the nozzle 9 to rotate to release part of the hose 10 when the nozzle 9 is far away from the storage box 12. At the same time, the hose 10 is elongated. The material of the hose 10 itself has a certain deformation ability. When the nozzle 9 is close to the storage box 12, the winding pile 13 rotates in the opposite direction to tighten the hose 10, thereby preventing the hose 10 from contacting the surface of the furniture product and affecting the painting effect.

[0032] Among them, only the bottom half of the inner side of the inner ring 4 is provided with driven teeth 5 .

[0033] In this embodiment, the rotation amplitude of the inner ring 4 at one time cannot exceed 180°, and it is necessary to ensure that the nozzle 9 is always above the conveyor belt 1. The driven teeth 5 only need to be arranged in half of the position in the inner ring 4 to achieve this.

[0034] Working principle: first put the furniture on the conveyor belt 1, and drive the furniture forward through the conveyor belt 1, start the motor 7 to drive the driving gear 6 to rotate, the driving gear 6 and the driven gear 5 engage to make the inner ring 4 rotate in the outer ring 3, the roller 8 lifts the inner ring 4, and the inner ring 4 rotates when cooperating with the driving gear 6, the inner ring 4 drives the nozzle 9 to rotate so as to adjust the angle between the nozzle 9 and the furniture, the nozzle 9 draws paint from the storage box 12 through the hose 10, and converts the paint into mist through the nozzle 9 to spray on the surface of the furniture to achieve painting, as the conveyor belt 1 drives the furniture forward, the motor 7 drives the inner ring 4 to rotate and constantly changes the direction of rotation, so that the nozzle 9 swings back and forth above the furniture, realizing multi-directional painting of the furniture without dead angles, greatly speeding up the painting speed.
