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

[0023] In practical implementation: such as Figure 1-5As shown, a wood furniture board surface spraying device includes a workbench 1, an auxiliary support frame 2, and a positioning support frame 3: the auxiliary support frame 2 is provided on the bottom outer wall of the workbench 1, the positioning support frame 3 is provided on the top outer wall of the workbench 1, the positioning support frame 3 is configured in an "n" shape, a homogenizing mixing mechanism 4 is provided above the positioning support frame 3, a spraying control mechanism 5 is provided on the side of the homogenizing mixing mechanism 4, and an abutment limiting mechanism 7 is provided above the workbench 1;

[0024] The homogenizing mixing mechanism 4 includes a paint storage tank 41, an auxiliary support base 42, a drive motor 43, a transmission shaft 44, a first stirring blade 45, and a second stirring blade 46. The top outer wall of the positioning support frame 3 is provided with a paint storage tank 41, the top outer wall of the paint storage tank 41 is provided with an auxiliary support base 42, the bottom outer wall of the auxiliary support base 42 is installed with a drive motor 43, the output end of the drive motor 43 is connected to the top outer wall of the transmission shaft 44, the first stirring blade 45 and the second stirring blade 46 are alternately installed on the outside of the transmission shaft 44 located inside the paint storage tank 41, the first stirring blade 45 is set as a spiral structure, and the second stirring blade 46 is set as a strip plate structure.

[0025] As per the instruction manual Figure 2 As shown, the top outer wall of the paint storage tank 41 is equipped with a feed pipe for replenishing paint into the paint storage tank 41. During use, paint can be injected into the paint storage tank 41 by connecting the pipe through the upper flange, or the paint can be poured directly into the paint storage tank 41 through the feed pipe, depending on the user's actual needs. However, it is necessary to ensure that the feed pipe remains closed during the subsequent paint homogenization process to prevent paint from overflowing through the feed pipe. When the paint is injected into the paint storage tank 41 through the feed pipe, the drive motor 43 is activated. The auxiliary support base 42 here provides auxiliary support to the drive motor 43. The drive motor 43 automatically drives the transmission shaft 44 to rotate when it is turned on, which in turn drives the first stirring blade 45 and the second stirring blade 46 to rotate simultaneously. Here, the first stirring blade 45 is set as a spiral structure so that when it rotates, it can automatically achieve a longitudinal mixing effect on the paint liquid inside the paint storage tank 41 through spiral rotation. The second stirring blade 46 is set as a strip plate structure so that when it rotates, it can automatically achieve a transverse mixing effect on the paint liquid inside the paint storage tank 41. Thus, the combination of the transverse and longitudinal directions can achieve a good homogeneous mixing effect on the paint liquid.

[0026] The paint spraying control mechanism 5 includes a paint pump 51, a delivery pipe 52, and an atomizing nozzle 53. The paint pump 51 is installed on the top outer wall of the positioning support frame 3. The inlet end of the paint pump 51 is connected to the paint storage tank 41 through a guide pipe, and the outlet end of the paint pump 51 is connected to the delivery pipe 52. The delivery pipe 52 is provided with multiple branch pipes, and the atomizing nozzle 53 is connected to the outlet end of the delivery pipe 52 at the branch pipe position. When it is necessary to use the paint liquid inside the paint storage tank 41 to spray the wooden furniture board, the paint pump 51 is turned on directly. When the paint pump 51 is turned on, it will automatically draw out the paint liquid from the paint storage tank 41 and deliver it into the delivery pipe 52. Then, through the delivery pipe 52, it is atomized and sprayed out through the atomizing nozzle 53. Then, through the spraying action of the atomizing nozzle 53, the paint liquid can be automatically sprayed onto the surface of the wooden furniture board to complete the painting process.

[0027] A support box 61 is provided on the top outer wall of the workbench 1. A control motor 62 is provided on the side outer wall of the support box 61. The output end of the control motor 62 is connected to one end of a reciprocating lead screw 63. The other end of the reciprocating lead screw 63 is rotatably installed on the side inner wall of the support box 61. A limit strip 64 is provided parallel to the side of the reciprocating lead screw 63. Both ends of the limit strip 64 are connected to the side inner wall of the support box 61. A support block 65 is provided through the outside of the reciprocating lead screw 63 and the limit strip 64. Connecting blocks 66 are symmetrically provided on the two outer walls of the support block 65. When it is necessary to control the movement of the placement seat 71 to achieve conveyor-type spraying of wooden furniture boards, then directly Turn on the control motor 62. When the control motor 62 is turned on, it will automatically drive the reciprocating screw 63 to rotate, which in turn drives the support block 65 to move. Due to the setting of the limit bar 64, the reciprocating screw 63 can only drive the support block 65 to achieve a horizontal sliding trajectory when it rotates. Then, the movement of the support block 65 will automatically drive the connecting block 66 to move, which in turn drives the placement seat 71 to move. When the placement seat 71 moves, it will automatically drive the wooden furniture board with internal limit to move. When the painting is finished and the material is picked up, simply turn off the control motor 62. Note that the control motor 62 has a self-locking function. After it is turned off, the placement seat 71 can still remain in the same position after the movement.

[0028] The contact limiting mechanism 7 includes a placement seat 71, connecting blocks 66 configured in an "L" shape, with the top outer walls of the two sets of connecting blocks 66 connected to the bottom outer wall of the placement seat 71. The placement seat 71 is configured in a "U" shape, with the bottom outer wall of the placement seat 71 slidably installed to the top outer wall of the support box 61. Limiting cylinders 72 are equally spaced embedded in the inner walls of both sides of the placement seat 71. Limiting piston rods 73 are slidably installed inside the limiting cylinders 72. A contact spring 74 is connected between the limiting piston rod 73 and the bottom inner wall of the limiting cylinder 72. The protruding end of the limiting piston rod 73 is located outside the limiting cylinder 72, and the protruding end of the limiting piston rod 73 is connected to the side outer wall of the clamping plate 75. When it is necessary to place the wood to be painted... When the furniture board is positioned inside the placement base 71, simply adjust the board to a suitable position and push it vertically to the middle position of the two sets of clamping plates 75. The clamping plates 75 will then automatically move to the side under the pressure, leaving a certain storage space for the board. At the same time, the side movement of the clamping plates 75 will simultaneously drive the limiting piston rod 73 to slide inside the limiting cylinder 72. At this time, the resisting spring 74 is in a contracted state due to the pressure of the limiting piston rod 73. Simultaneously, the resisting spring 74 generates a reaction force under the pressure, which will automatically push the limiting piston rod 73 to move in the opposite direction. The reverse movement of the limiting piston rod 73 will automatically push the clamping plate 75 to fit against the outer wall of the board, thereby achieving the effect of limiting and resisting the board.

[0029] Two sets of clamping plates 75 are provided, and the top outer wall of both sets of clamping plates 75 is set with an arc structure. The above configuration makes the resistance encountered by the plate when it is pushed into the two sets of clamping plates 75 less, making it easier to pick up and put down. It is also recommended that the clamping plates 75 should not be smooth, but have some texture, so as to increase the contact friction between the clamping plates 75 and the plate and better resist and limit the plate.

[0030] When using this utility model, the plate to be painted is first placed inside the placement seat 71 for positioning. During placement, the plate is simply adjusted to a suitable position and then pushed vertically to the middle position of the two sets of clamping plates 75. The clamping plates 75 are then automatically moved to the side under the pressure, leaving a certain storage space for the plate. At the same time, the movement of the clamping plates 75 to the side will simultaneously drive the limiting piston rod 73 to slide inside the limiting cylinder 72. At this time, the resisting spring 74 is in a contracted state due to the pressure of the limiting piston rod 73. Simultaneously, the resisting spring 74 generates a reaction force under the pressure, which will automatically push the limiting piston rod 73 to move in the opposite direction. The reverse movement of the limiting piston rod 73 will automatically push the clamping plate 75 to fit against the outer wall of the plate, thereby achieving the effect of limiting and resisting the plate.

[0031] When starting the painting process, the paint pump 51 must first be turned on. Once the paint pump 51 is turned on, it will automatically draw the paint from the paint tank 41 and deliver it into the delivery pipe 52. Then, the paint is delivered through the delivery pipe 52 and atomized by the atomizing nozzle 53. The placement seat 71 is then moved to achieve conveying painting of the wooden furniture board. At this point, the control motor 62 is turned on. When the control motor 62 is turned on, it will automatically drive the reciprocating screw 63 to rotate, thereby moving the support block 65. Due to the setting of the limit bar 64, the reciprocating screw 63 can only move the support block 65 horizontally during rotation. The sliding trajectory movement of the support block 65 will automatically drive the connecting block 66 to move, thereby driving the placement seat 71 to move. When the placement seat 71 moves, it will automatically drive the wooden furniture board with internal limit to move. When the painting is finished and the material is picked up, the control motor 62 can be turned off directly. It should be noted that the control motor 62 has a self-locking function. After it is turned off, the placement seat 71 can still remain in the same position after the movement. When the board passes through the spraying area during the movement, the paint can be automatically sprayed onto the surface of the wooden furniture board through the spraying action of the atomizing nozzle 53, thereby completing the painting process.

[0032] It should be noted that the aforementioned drive motor 43 and control motor 62 can be powered using existing operating techniques, which are conventional operating techniques and will not be described in detail here.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
