[0002] The coating mechanism is a kind of equipment specially used for the spraying dyeing treatment of solid wood board, and its working principle is to place the solid wood board on the conveying device, and enter the spraying area with the movement of the conveying device.The paint supply system delivers paint to the spray head, and the spray head atomizes and uniformly sprays the paint to the surface of the board.

[0003] On the traditional spraying line, the board is usually positioned and conveyed by manual or simple mechanical device. However, the elasticity and deformability of wood itself cause slight movement or tilting of the board during the conveying process even if it is in the correct initial position, resulting in uneven spraying.

[0036] The side close to each other of two support plates 7 is rotatably connected with three positioning shafts 9, these positioning shafts 9 can rotate freely on support plate 7, and their bottom end is slidingly connected at the top end of transmission belt one 3.The purpose of this design is to position and correct wood board during wood board transmission, ensure that wood board can accurately enter spraying area.

[0037] The left end of the transmission belt 3 is rotatably connected with the support rods 10 on both sides, which support the cleaning roller 11 to rotate above the transmission belt 3. The top ends of the two support rods 10 are rotatably connected with the cleaning roller 11, which is a roller with bristles to clean dust and impurities on the surface of the wood board to improve the spraying effect.

[0038] The left side of the inside of the spraying cover 2 is provided with a spraying assembly 12, which is a key component responsible for uniformly spraying paint onto the surface of the wood board. The spraying assembly 12 usually includes a spray gun, a nozzle, and other related control systems.

[0039] Reference Figure 3 The top end of the spraying cover 2 is provided with a feeding assembly, which includes a stirring tank 13, which is a container for storing and stirring paint. The bottom end of the outside of the stirring tank 13 is fixedly connected to the right side of the top end of the spraying cover 2, which is designed to facilitate operation and maintenance. The left side of the stirring tank 13 is fixedly connected with a flow guide pipe 14, which is a pipeline for conveying the stirred paint to the position of the spraying assembly 12. The flow guide pipe 14 is arranged on the right side of the spraying assembly 12, which can ensure the smooth flow of paint into the spraying area.

[0040] Reference Figure 4 and Figure 5 The right side of the top end of the spraying cover 2 is fixedly connected with a motor 15, which is a driving device for providing power to the entire spraying system. The driving end of the motor 15 is fixedly connected with a connecting roller 16, which is a transmission element for transmitting the power of the motor 15. The outer side of the connecting roller 16 is rotatably connected to the right side of the front end of the spraying cover 2, which is designed to save space and improve transmission efficiency. The bottom end of the connecting roller 16 is fixedly connected with a turntable 17, which is a rotatable platform for installing a warm air frame 20 and other related components. The top end of the outside of the turntable 17 is provided with a positioning hole 18, which is a hole position for fixing the T-shaped part 23.

[0041] The inside of the spraying cover 2 is rotatably connected with the rotating shaft 19 on both sides, which is two parallel shafts for supporting the warm air frame 20 and enabling it to swing left and right. The proximal side of the two rotating shafts 19 is fixedly connected with the warm air frame 20, which is a heating device for drying the wood board after spraying. The front and rear sides of the warm air frame 20 are rotatably connected to the right side of the inner wall of the spraying cover 2, which is designed to increase the stability and flexibility of the warm air frame 20. The top end of the warm air frame 20 is fixedly connected with the protruding block 21 on both sides, which is two protruding parts for installing the fixed roller 22.

[0042] The middle part of the two protrusions 21 is fixedly connected with a fixed roller 22, which is a rotatable roller for supporting the T-shaped part 23 and enabling it to slide on the warm air frame 20. The outer part of the fixed roller 22 is slidingly connected with the T-shaped part 23, which is a part shaped like a "T" for connecting the warm air frame 20 and the rotating disc 17. The bottom end of the T-shaped part 23 is slidingly connected to the inner wall of the positioning hole 18, and the purpose of this design is to enable the warm air frame 20 to swing left and right together with the rotating disc 17.

[0043] The top right side of the control box 1 is provided with a conveying belt two 24, which is a horizontal conveying device for conveying the finished wood board from the spraying area to the next work station or the outlet. The spraying cover 2 is sleeved outside the conveying belt two 24, and the purpose of this design is to protect the wood board during the conveying process from the external environment.

[0044] Working principle: in use, the solid wood board is placed on the top end of the conveying belt one 3 by passing through the gap between the cleaning roller 11 and the conveying belt one 3, and at this time, the dust particles on the surface of the wood board are removed by the cleaning brush of the cleaning roller 11, and then the wood board is driven by the activated conveying belt one 3 to the position of the spraying cover 2. During the transmission process, the wood board is conveyed to the position of the positioning shaft 9, at this time, the surface of the wood board contacts the positioning shaft 9 and drives the positioning shaft 9 to expand around the supporting block 4, and at the same time, the positioning shaft 9 drives the stop block 8 to rotate in the same direction to extrude the top roller of the torsional spring 6, causing the torsional spring 6 to twist. After the torsional spring 6 is twisted, because the bottom roller of the torsional spring 6 is fixed to the outside of the conveying belt one 3, it will reset to push the stop block 8 and the supporting plate 7 to reset, so that the supporting plate 7 drives the positioning shaft 9 to flexibly clamp the two sides of the wood board, correcting the center position of the wood board, and ensuring that the wood board is accurately conveyed by the conveying belt one 3 into the spraying cover 2.

[0045] When the wood board is conveyed into the spraying cover 2, the spraying assembly 12 is activated by pneumatic kinetic energy to make the spraying head on the spraying assembly 12 slide back and forth on the surface of the wood board repeatedly, so that the wood board can be quickly and evenly dyed.

[0046] Finally, the wood board is conveyed by the activated conveying belt two 24 to gradually move to the right side. During the movement, because the motor 15 at the top end of the wood board and the warm air frame 20 are turned on after the spraying is completed, the motor 15 drives the rotating disc 17 to rotate, so that the T-shaped part 23 in the positioning hole 18 of the rotating disc 17 rotates along the rotating disc 17, thereby sliding on the outside of the fixed roller 22. The swinging of the T-shaped part 23 makes the warm air frame 20 swing left and right around the rotating shaft 19, increasing the drying area and ensuring that the warm air blows evenly to every part of the board.

[0047] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
