DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-6 As shown, the painting device includes a frame 1, a primer device 3 and a topcoat device 2. The primer device 3 and the topcoat device 2 are located on the frame 1. The primer device 3 and the topcoat device 2 are located on the same horizontal line. The primer device 3 is used for spraying primer on wood, and the topcoat device 2 is used for spraying topcoat on primed wood.

[0026] A conveying component 1-1 and a roller group 4 are provided on the frame 1. The positions of the primer device 3 and the topcoat device 2 are adapted to the conveying component 1-1. The roller group 4 is located between the primer device 3 and the conveying component 1-1, and a roller group 4 is also provided between the conveying component 1-1 and the topcoat device 2; the roller group 4 includes an inclined first roller 4-1 and a second roller 4-2, and the first roller 4-1 and the second roller 4-2 are cross-arranged.

[0027] The first roller 4-1 and the second roller 4-2 are made of soft material, and the first roller 4-1 and the second roller 4-2 are coated with primer or topcoat for coating the wood surface.

[0028] A first connecting piece 4-3 is provided between the first roller 4-1 and the frame 1, the first connecting piece 4-3 is rotatably connected to the first roller 4-1, and the first connecting piece 4-3 is located above the transmission component 1-1, and a second connecting piece 4-4 is provided between the second roller 4-2 and the frame 1, the second connecting piece 4-4 is rotatably connected to the second roller 4-2, and the second connecting piece 4-4 is located below the transmission component 1-1.

[0029] The first connecting piece 4-3 and the second connecting piece 4-4 are used to support the positions of the first roller 4-1 and the second roller 4-2. The first roller 4-1, the second roller 4-2 and the conveying component 1-1 are located at the same horizontal height. When the wood moves on the conveying component 1-1, it is convenient for the first roller 4-1 and the second roller 4-2 to contact with the wood.

[0030] The first roller 4-1 and the second roller 4-2 are located at the same horizontal height. The first roller 4-1 is relative to the second roller 4-2. The first roller 4-1 is located at the front end of the conveying direction of the conveying component 1-1. The first roller 4-1 is inclined upward toward the end of the frame 1, and the second roller 4-2 is inclined downward toward the end of the frame 1.

[0031] When the wood moves on the conveying assembly 1-1, it first passes through the first roller 4-1 and then passes through the second roller 4-2. The first roller 4-1 and the second roller 4-2 form a 45-degree angle with the frame 1. The first roller 4-1 is used to paint the upper end of the wood, and the second roller 4-2 is used to paint the lower end of the wood. Since the paint has a certain fluidity, after the first roller 4-1 paints the wood, the paint flows downward under the action of gravity. When the second roller 4-2 paints the lower end of the wood, it also evenly spreads the excess paint, so that the wood has a better painting effect.

[0032] The conveying assembly 1-1 includes a base plate 1-3 and multiple transmission wheels 1-2. The multiple transmission wheels 1-2 are located above the base plate 1-3 and are located on the same horizontal line. Conveyor belts 1-4 are provided on the multiple transmission wheels 1-2. The multiple transmission wheels 1-2 are arranged in sequence. The base plate 1-3 is used to support the wood. The rotation of the transmission wheel 1-2 drives the rotation of the conveyor belt 1-4, thereby driving the wood to move along the direction of the conveyor belt 1-4. At the same time, the transmission wheel 1-2 also plays a role in pressing the wood, so that the wood has better stability on the base plate 1-3.

[0033] The primer device 3 includes a paint pool 3-1, a first base 3-2 and a second base 3-3. The first base 3-2 and the second base 3-3 are located above the paint pool 3-1, and the first base 3-2 and the second base 3-3 are located on both sides of the center of the paint pool 3-1. The paint pool 3-1 is provided with an upward opening. The paint pool 3-1 is used to store and recover paint. The paint pool 3-1 is located below the roller group 4 to recover the paint that is produced during the painting process and that drips naturally from the roller group 4.

[0034] A first telescopic rod 3-4 is provided between the first base 3-2 and the paint pool 3-1, and the first telescopic rod 3-4 extends upward along the direction of the paint pool 3-1. A second telescopic rod 3-5 is provided between the second base 3-3 and the paint pool 3-1, and the second telescopic rod 3-5 extends upward along the direction of the paint pool 3-1. A pneumatic diaphragm pump 3-12 is provided on both the first base 3-2 and the second base 3-3, and the pneumatic diaphragm pump 3-12 is connected to the paint pool 3-1 through a pipeline, and a nozzle 3-13 is provided on the pneumatic diaphragm pump 3-12, and the nozzle 3-13 faces the roller group 4.

[0035] The pneumatic diaphragm pump 3-12 is a new type of conveying machinery, which uses compressed gas as a power source. It can completely pump out various corrosive liquids, liquids with particles, high-viscosity, volatile, flammable, and highly toxic liquids. Under the action of the pneumatic diaphragm pump 3-12, the paint in the paint pool 3-1 is extracted and sprayed out from the nozzle 3-13. The first base 3-2 and the second base 3-3 are both provided with nozzles 3-13, and the two nozzles 3-13 correspond to the first roller 4-1 and the second roller 4-2 respectively.

[0036] The first base 3-2 and the second base 3-3 are used to support the pneumatic diaphragm pump 3-12. The first telescopic rod 3-4 and the second telescopic rod 3-5 are connected with a cylinder or a hydraulic cylinder. Under the action of the first telescopic rod 3-4 and the second telescopic rod 3-5, the first base 3-2 and the second base 3-3 are lifted and lowered, so that the nozzle 3-13 can better correspond to the first roller 4-1 and the second roller 4-2.

[0037] A first supporting block 3-6 is provided on the top of the first telescopic rod 3-4, a first matching seat 3-7 and a first piston rod 3-8 are provided between the first supporting block 3-6 and the first base 3-2, the first matching seat 3-7 is fixedly connected to the first base 3-2, the first piston rod 3-8 passes through the first matching seat 3-7, and the first piston rod 3-8 is fixedly connected to the first matching seat 3-7. Similarly, a second supporting block 3-9 is provided on the top of the second telescopic rod 3-5, a second matching seat 3-10 and a second piston rod 3-11 are provided between the second supporting block 3-9 and the second base 3-3, the second matching seat 3-10 is fixedly connected to the second base 3-3, the second piston rod 3-11 passes through the second matching seat 3-10, and the second piston rod 3-11 is fixedly connected to the second matching seat 3-10.

[0038] The first telescopic rod 3-4 and the second telescopic rod 3-5 drive the first base 3-2 and the second base 3-3 to move vertically, and the first piston rod 3-8 and the second piston rod 3-11 drive the first base 3-2 and the second base 3-3 to move horizontally, so that the nozzle 3-13 can better correspond to the first roller 4-1 and the second roller 4-2.

[0039] The primer device 3 also includes a drying component 5, which includes a shell 5-1 and a heating element 5-2. The heating element 5-2 is located in the shell 5-1, and the heating element 5-2 faces the conveying component 1-1. The drying component 5 is relative to the paint pool 3-1. The drying component 5 is located at the rear end of the conveying direction of the conveying component 1-1. After the roller group 4 paints the wood, the paint on the wood is dried and fixed by the drying component 5, so that the paint can better adhere to the wood.

[0040] The structure of the topcoat device 2 is the same as that of the primer device 3. After the wood is painted with primer on the primer device 3, the wood and the primer are dried and fixed by the drying component 5, and then the wood is painted with topcoat on the topcoat device 2, and then the wood and the topcoat are dried and fixed by the drying component 5.
