[0002] Rattan is a natural weaving material. It is also called "rattan strips". It is a tough and long vine plant. The outer skin of rattan is shiny, smooth to the touch, and extremely elastic. It looks like rattan but is not rattan. It is also often used to weave rattan chairs, rattan boxes and other daily utensils.

[0003] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the paint into uniform and fine droplets with the help of pressure or centrifugal force, and then applies it to the surface of the object to be coated. During the furniture manufacturing process, the furniture is sprayed to protect its surface, thereby improving the user's comfort and the aesthetic appearance of the furniture.

[0004] When existing spraying equipment is used to spray rattan furniture, since rattan furniture is not an object with a regular shape and the rattan furniture or the spray gun can only rotate horizontally in one direction, it is easy to affect the uniformity of the spraying on the surface of the rattan furniture, destroy the beauty of the furniture, and greatly reduce the user experience.

[0032] Specifically, the rattan furniture is fixed above the swing mechanism 40. When the swing mechanism 40 is swinging, since the swing mechanism 40 is located at the center of the partition 12, the rattan furniture will not collide with the inner wall of the spray box 11 and the spray mechanism 50. When the rattan furniture is shaking, the spray mechanism 50 continues to spray the surface of the rattan furniture, thereby improving the uniformity of the spraying, avoiding reducing the beauty of the rattan furniture, and ensuring the user experience.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the rocking mechanism 40 includes a rocking arm 41, the outer ring of the rocking arm 41 is fixedly sleeved with a universal joint 42, the universal joint 42 is movably sleeved in the inner ring of the universal sleeve 13, the top of the rocking arm 41 is fixedly connected with a placement platform 43, and the tail end extends to the interior of the pushing mechanism 30, and a plurality of detachable fixing seats 44 are installed on the top of the placement platform 43. The rocking arm 41 is controlled by the pushing mechanism 30 to swing with the universal sleeve 13 as the axis, thereby improving the uniformity of the spraying mechanism 50 on the surface of the rattan furniture fixed on the fixing seat 44.

[0034] Specifically, the rocking arm 41 and the universal joint 42 are fixed by bolts, and the shaking amplitude of the placement platform 43 can be further adjusted by adjusting the height of the rocking arm 41 .

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the pushing mechanism 30 includes a circular frame 31 and a circular frame 35, both of which are slidably connected to the inner wall of the spray box 11, and the angle between the circular frame 31 and the circular frame 35 is 90°, and the tail end of the rocking arm 41 extends to the interior of the circular frame 31 and the circular frame 35.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the driving mechanism 20 includes a motor 21 fixed on the inner wall of the bottom of the spray box 11, the output end of the motor 21 is fixedly connected to a rotating shaft 22, and the outer ring of the rotating shaft 22 is fixedly sleeved with two cams 23, and the two cams 23 are respectively located inside the circular frame 2 34 and the circular frame 4 37.

[0039] Specifically, the starting motor 21 drives the two cams 23 to rotate simultaneously through the rotating shaft 22. The rotation of the two cams 23 will drive the circular frame 1 31 and the circular frame 3 35 to slide on the inner wall of the spray box 11 through the circular frame 2 34 and the circular frame 4 37, so that the circular frame 1 31 and the circular frame 3 35 push the tail end of the rocking arm 41 to move axially in two different directions, so that the rocking arm 41 and the placement platform 43 swing with the universal joint 42 as the axis, so that the rattan furniture shakes continuously during the spraying process, thereby improving the uniformity of the spraying.

A gear 57 is fixedly connected to the output end of the motor 2 56, and the gear 57 is meshed with the gear ring 55 for transmission.

[0046] Specifically, the starting motor 56 drives the gear 57 to rotate, and the engagement of the gear 57 with the gear ring 55 drives the turntable 51 to rotate in the top inner circle of the spray box 11. During the rotation, the paint located inside the paint box 52 is pumped into the inside of the delivery pipe 53 through the pump, and finally the surface of the rattan furniture is sprayed by the nozzle 54.

[0047] The spraying method of the rattan furniture surface spraying device comprises the following steps:

[0048] S1. Fixing of rattan furniture:

[0049] Adjust the number of fixing seats 44 and their positions on the placement platform 43 according to the positions of the rattan furniture legs, and then close the window of the spray box 11;
