[0015] A method for using a wood board spray painting device for waterproof cabinet processing comprises the following steps:

[0016] S1. Place the wooden board to be painted on the wooden board placement base, adjust the spacing of the arc-shaped shell to match the front and back dimensions of the wooden board, and adjust the spacing between the rotating push frame and the T-shaped plate to the other side of the T-shaped plate to match the left and right dimensions of the wooden board;

[0017] S2, pull the meshing movable block out from the inside of the rotating clamping seat, rotate the rope fixing column to wrap the connecting ropes on both sides around its surface, reduce the distance between the front clamping block and the rear clamping block, clamp the paint spray nozzle to deform and change the paint spraying range, put the meshing movable block into the rotating clamping seat to maintain the current state, and start the spray gun body and the drive motor;

[0018] S3, the driving motor drives the threaded shaft to rotate and drives the mobile platform to move on the mobile mounting frame, driving the spray gun body to move for spraying paint, when the mobile platform approaches the T-plate on the rotating rack side, the pushing protrusion will contact the path groove to generate displacement, and push and pull the horizontal rotating shaft, the rotating gear will still be partially engaged with the rotating rack, the rotating gear rotates and drives the lifting gear at the other end to rotate, the lifting gear is partially engaged with the lifting rack at this time, and the rotation is converted into direct motion while rotating, thereby driving the entire mobile mounting frame to move, until the pushing protrusion is pushed to the limit position, the horizontal rotating shaft is completely pushed out, at this time the rotating gear will no longer be engaged with the rotating rack, when the mobile platform returns, the lifting gear will not cause the mobile mounting frame to move in the opposite direction due to reversal, when moving to the front or rear end, the T-plates on both sides are flipped at the same time, and the path grooves on the T-plates on both sides are also opposite, at this time, when the mobile platform approaches the rotating rack, the rotating gear will not contact the rotating rack, but engage when it is far away, because the direction of the rotating gear and the lifting gear is opposite to before, the entire mobile mounting frame is driven to move in the opposite direction;

[0019] S4. When the mobile mounting frame moves to both sides, the straight bracket at the front end and the arc bracket at the rear end contact the corresponding arc-shaped shell when moving forward and backward respectively, thereby driving the external rotating block and the internal rotating block to rotate synchronously. The internal rotating block and the driven rotating block are connected by a rotating connecting rod to form a parallel double crank structure, which rotates synchronously to drive the spray gun body to rotate. When the spray gun body is spraying paint obliquely on both sides, it can just spray paint on the side of the wooden board. When it is in the middle position, the center of gravity is downward, and the spray gun body is perpendicular to the wooden board again. When the mobile platform drives the fixed base and the rotating base to move to the rotating push frame, the bending of one side of the rotating push frame will push the rotating base to rotate around the connection with the fixed base, and drive the spray gun body to rotate, spray paint on the side left side of the wooden board, and when it is away from the rotating push frame, the reset spring drives the fixed base and the rotating base to reset and return to the painting state perpendicular to the wooden board;

[0020] When the front, front and rear sides and left side are painted, the paint is dried and then turned over. At this time, the device will paint the remaining sides and the back.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In the present invention, through the setting of the nozzle moving mechanism, during use, the driving motor drives the moving platform and the spray gun body to move along a predetermined path, and after one reciprocating spraying, it will drive the entire spraying part to move forward or backward for a distance, thereby increasing the operating range of the spray gun body, so that the entire wooden board surface can be evenly covered.

[0023] In the present invention, the forward and backward rotation of the spray gun body is achieved through the coordinated use of the front and rear rotation mechanism and the side rotation mechanism, which enables the spray gun to spray paint on the side of the wooden board and the left side of the wooden board, and reset after the operation is completed, which provides flexible painting angles and a wide coverage range, ensuring the efficiency and comprehensiveness of the painting operation.

[0024] In the present invention, the shape of the paint spray nozzle is changed by setting the nozzle control mechanism, thereby adjusting the paint spray range, providing precise control of the paint spray details, allowing the operator to adjust the paint coverage area as needed, and improving the flexibility and adaptability of the paint spray operation.

A paint spray nozzle 62 is fixedly connected to the outer surface of the paint spray nozzle 62. A nozzle control mechanism 7 is arranged on the outer surface of the paint spray device housing 1 for installing and protecting the remaining components. The wooden board placement base 11 provides a platform for placing wooden boards. The wooden boards are placed flat on the surface of the wooden board placement base 11. The movable mounting frame 21 is installed on the surface of the supporting beam 2 and can slide to drive the spray gun body 6 to move, thereby increasing the painting range of the spray gun body 6. The paint spray barrel 61 stores the paint inside, which is sprayed onto the surface of the placed wooden board through the paint spray nozzle 62.

[0040] The nozzle moving mechanism 3 includes a driving motor 31, which is fixedly connected to the inner surface of the moving mounting frame 21, and a threaded shaft 32 is fixedly connected to the output end of the driving motor 31. The outer surface of the threaded shaft 32 is slidably connected to a sliding base 322, and the top surface of the sliding base 322 is rotatably connected to a T-plate 33. The outer surface of the T-plate 33 is provided with a path groove 331, and the outer surface of the moving mounting frame 21 is magnetically connected to a magnetic card block 332. The outer surface of the threaded shaft 32 is threadedly connected to a moving platform 35, and the top surface of the moving platform 35 is provided with a convex sliding groove 351. The inner surface of the moving platform 35 is slidably connected to a transverse rotating shaft 36, and the outer surface of the transverse rotating shaft 36 is provided with a mounting groove 361. The outer surface of 361 is rotatably connected with a rotating shell 3611, and the outer surface of the rotating shell 3611 is fixedly connected with a pushing protrusion 3612, one end of the horizontal rotating shaft 36 is fixedly connected with a lifting gear 362, and the other end of the horizontal rotating shaft 36 is fixedly connected with a rotating gear 363, the outer surface of the mobile mounting frame 21 is fixedly connected with a rotating rack 37, and the inner surface of the paint spraying device shell 1 is fixedly connected with a lifting rack 38, and the outer surface of the lifting rack 38 is provided with a rack connecting groove 381. Through the setting of the nozzle moving mechanism 3, during use, the driving motor 31 drives the threaded shaft 32 to rotate inside the mobile mounting frame 21, and the rotation is converted into linear movement through the threaded connection with the mobile platform 35. By controlling the driving motor 3 1, and the forward and reverse rotation and speed of the mobile platform 35 are controlled to control the moving direction and speed of the mobile platform 35, so as to realize the long-distance movement of the subsequent spray gun body 6. A transverse rotating shaft 36 that can move laterally is installed inside the mobile platform 35. The friction generated by the close fit can overcome the influence of gravity, so that the position of the transverse rotating shaft 36 on the mobile platform 35 will not change when it is not affected by external forces. A rotating shell 3611 is installed on the surface of the transverse rotating shaft 36 through a mounting groove 361. The rotating shell 3611 can rotate on the transverse rotating shaft 36 and drag the transverse rotating shaft 36 to move. The pushing protrusion 3612 extending from the rotating shell 3611 is installed in the protrusion sliding groove 351, which limits the moving path of the pushing protrusion 3612 and makes it always extend to the mobile platform 3 5, during the movement of the mobile platform 35, if it contacts the T-shaped plates 33 on both sides, the pushing protrusion 3612 will contact the path groove 331 to generate displacement, and push and pull the horizontal shaft 36. When the mobile platform 35 moves to the side close to the rotating rack 37, since the horizontal shaft 36 is close to the inside at this time, the rotating gear 363 will mesh with the rotating rack 37, so that the rotating gear 363 rotates and drives the lifting gear 362 at the other end to rotate. The lifting gear 362 is now partially meshed with the lifting rack 38, and the rotation is converted into direct motion while rotating, thereby driving the entire mobile mounting frame 21 to move. During the movement of the mobile platform 35, the pushing protrusion 3612 will slide in the path groove 331, thereby gradually pushing the horizontal shaft 36.However, the rotating gear 363 will still be partially engaged with the rotating rack 37 until the pushing protrusion 3612 is pushed to the limit position and the horizontal shaft 36 is completely pushed out. At this time, the rotating gear 363 will no longer be engaged with the rotating rack 37. When the mobile platform 35 returns, the lifting gear 362 will not rotate. In this way, the lifting gear 362 will not cause the mobile mounting frame 21 to move in the opposite direction due to the reversal when returning. When the mobile platform 35 moves to the T-shaped plate 33 on the other side, the pushing protrusion 3612 contacts the path groove 331 on that side, and the horizontal shaft 36 is pulled back again, so that the rotating gear 363 can contact the rotating rack 37 when they approach next time, so that the entire mobile mounting frame 21 and the spray gun body 6 will move forward a certain distance every time the mobile platform 35 and the spray gun body 6 go back and forth, so that the spray gun body 6 can completely cover the entire wooden board surface.

[0041] The other end of the threaded shaft 32 is rotatably connected to the inner surface of the mobile mounting frame 21, the number of T-shaped plates 33 is two, the outer surface of the mobile mounting frame 21 is rotatably connected to the T-shaped plate 33, and the magnetic card block 332 is magnetically connected to the T-shaped plate 33, the number of path grooves 331 on each T-shaped plate 33 is two, and the two path grooves 331 are symmetrically distributed with the central axis of the T-shaped plate 33 as the symmetry axis, the push protrusion 3612 is slidably connected to the inner surface of the protrusion sliding groove 351, and the push protrusion 3612 The movable platform 35 is closely attached to the horizontal rotating shaft 36, the rotating gear 363 is meshed with the rotating rack 37, the rotating gear 363 is slidably connected to the outer surface of the movable mounting frame 21, the lifting gear 362 is meshed with the lifting rack 38, the T-shaped plate 33 near the rotating rack 37 is connected to the movable mounting frame 21, and the rotating connection position between the T-shaped plate 33 and the movable mounting frame 21 remains unchanged and can only rotate, the magnetic card block 332 is magnetically attracted between the T-shaped plate 33 and the movable mounting frame 21, and the T-shaped plate 33 is connected to the movable mounting frame 21. After the movement is completed, it is stuck to prevent rotation, and the T-plate 33 on the other side is rotatably connected to the sliding base 322. The sliding base 322 can move on the threaded shaft 32 to drive the T-plate 33 on this side to move. By changing the spacing of the T-plate 33 on this side, it can adapt to the painting of wooden boards of different sizes. Since the T-plate 33 is rotatable, in the initial state, when the moving platform 35 is close to the rotating rack 37, the rotating gear 363 will contact the rotating rack 37 to drive the entire moving mounting frame 21 to move, and no longer contact when moving away to prevent reverse movement. The T-plates 33 on both sides are flipped at the same time, and the path grooves 331 on the T-plates 33 on both sides are also opposite. At this time, when the moving platform 35 is close to the rotating rack 37, the rotating gear 363 will not contact the rotating rack 37, but will mesh when moving away. Since the rotation direction of the rotating gear 363 and the lifting gear 362 is opposite to that before, the entire moving mounting frame 21 is driven to move in the opposite direction, so that the moving mounting frame 21 can move both forward and reverse, increase the coverage area and achieve the reset effect after movement.

[0042] The front-to-back rotation mechanism 4 includes a front-end mounting plate 41, which is fixedly connected to the top surface of the mobile platform 35, a rotation limit block 411 is fixedly connected to the inner surface of the front-end mounting plate 41, an outer surface of the front-end mounting plate 41 is rotationally connected to an external rotation block 42, an outer surface of the external rotation block 42 is fixedly connected to a straight bracket 421, and the other side surface of the external rotation block 42 is fixedly connected to an arc bracket 422, one end of the arc bracket 422 is rotationally connected to a contact wheel 423, the inner surface of the front-end mounting plate 41 is rotationally connected to an internal rotation block 43, and the outer surface of the internal rotation block 43 is rotationally connected to a rotation The inner surface of the connecting rod 44 and the front mounting plate 41 is rotatably connected to a driven rotating block 45, and the inner surface of the paint spraying device housing 1 is slidably connected to an arc-shaped housing 46. The two ends of the arc-shaped housing 46 are fixedly connected to threaded columns 461, and the outer surface of the threaded column 461 is threadedly connected to a locking bolt 462. Through the setting of the front and rear rotating mechanism 4, during use, when the mobile mounting frame 21 moves to both sides, the front straight bracket 421 and the rear arc bracket 422 contact the corresponding arc-shaped housing 46 when moving forward and backward respectively, and the straight bracket 421 and the arc bracket 422 are fixedly connected to the external rotating block 42. The arc bracket 422 is arc-shaped to prevent contact with the mobile mounting bracket 21. When the contact wheels 423 on the straight bracket 421 and the arc bracket 422 contact the inside of the arc-shaped housing 46, the outer rotating block 42 will be driven to rotate due to the arc-shaped interior. The rotating shaft of the outer rotating block 42 penetrates into the front mounting plate 41 to drive the inner rotating block 43 to rotate synchronously. The inner rotating block 43 and the driven rotating block 45 are connected by a rotating connecting rod 44 to form a parallel double crank structure, so that the rotation of the inner rotating block 43 and the driven rotating block 45 are synchronized, and the spray gun body 6 is driven to rotate through the driven rotating block 45. The rotation limit block 411 limits The maximum rotation angle of the internal rotating block 43 is controlled, so that when the spray gun body 6 moves with the mobile mounting bracket 21, if it is in the middle position because the center of gravity is at the bottom, it will not rotate and always remain parallel to the painted wooden board. When it moves to both sides with the mobile mounting bracket 21, if the straight bracket 421 and the arc bracket 422 are in contact with the arc shell 46 at this time, it will rotate to paint the wooden board obliquely. The arc shell 46 can slide in the rack connecting groove 381 and be fixed by the threaded column 461 and the locking bolt 462. The spacing of the arc shell 46 matches the wooden board. When the spray gun body 6 is painted obliquely, the side of the wooden board can be painted.

[0043] The external rotating block 42 is fixedly connected to the internal rotating block 43 and the connection passes through the front end mounting plate 41. The internal rotating block 43 is slidably connected to the outer surface of the rotating limit block 411. One end of the straight bracket 421 is rotatably connected to the contact wheel 423. The other end of the rotating connecting rod 44 is rotatably connected to the driven rotating block 45. There are two arc-shaped outer shells 46. The threaded column 461 is slidably connected to the inner surface of the rack connecting groove 381. The internal rotating block 43 is driven to rotate by the external rotating block 42, and the rotation is transmitted to the driven rotating block 45 through the rotating connecting rod 44. The symmetrical arc-shaped outer shells 46 correspond to the front and rear sides of the wooden board respectively, so that the spray gun body 6 can spray paint on both sides and the front of the wooden board.

When the mobile platform 35 drives the fixed base 51 and the rotating base 52 to move to the rotating push frame 54, the bending of one side of the rotating push frame 54 will push the rotating base 52 to rotate around the connection with the fixed base 51, and drive the spray gun body 6 to rotate. The rotating push frame 54 can move on the movable mounting frame 21 and be fixed by bolts, and the rotating push frame 54 and the T-shaped plate 33 are also connected by bolts. The rotating push frame 54 can limit the rotation of the T-shaped plate 33 on the side without the magnetic card block 332, and adjust the position according to the size of the wooden board. In this way, when the spray gun body 6 rotates, the left side of the side of the wooden board can be sprayed with paint, and when it is away from the rotating push frame 54, the reset spring 521 drives the fixed base 51 and the rotating base 52 to reset and return to a painting state perpendicular to the wooden board.

[0045] The connection between the fixed base 51 and the driven rotating block 45 passes through the front mounting plate 41 and is rotatably connected to the inner wall thereof. The rotating limit frame A511 is slidably connected to the rotating limit frame B522. The two ends of the return spring 521 are respectively fixedly connected to the fixed base 51 and the rotating base 52. The spray gun body 6 is fixedly connected to the paint spray mounting seat 53. The rotating push frame 54 is bolted to the movable mounting frame 21 through the bolt connection groove 22. The rotating push frame 54 is slidably connected to the fixed base 51 and the rotating base 52. The rotating push frame 54 is bolted to the T-shaped plate 33.

The column 76 wraps the connecting ropes 73 on both sides around its surface, and the distance between the front clamping block 72 and the rear clamping block 721 will be reduced, thereby clamping the internal mounting shell 71, and finally clamping the paint spray head 62 to cause it to undergo a recoverable plastic deformation, thereby changing the range of a single painting. After the engaging movable block 75 is placed into the rotating snap seat 74, the groove on the engaging movable block 75 will engage with the protrusion of the rotating snap seat 74, preventing the engaging movable block 75 and the rope fixing column 76 from rotating to maintain the current state. The mounting shell 71 can rotate on the paint spray head 62 to freely select the shape of the deformation after clamping. After the rope fixing column 76 releases the connecting rope 73, the paint spray head 62 is reset under the action of its own elasticity.

[0047] There are two connecting ropes 73, and the two connecting ropes 73 are symmetrically distributed with the central axis of the rear end clamping block 721 as the symmetry axis. The connecting rope 73 passes through the front end clamping block 72, and the other end of the connecting rope 73 is fixedly connected to the rope fixing column 76. The front end clamping block 72 and the rear end clamping block 721 are both slidingly connected to the outer surface of the paint spray nozzle 62. The symmetrical connecting ropes 73 disperse the force, and the distance between the front end clamping block 72 and the rear end clamping block 721 is changed by the connecting rope 73, so as to achieve clamping and changing the shape of the paint spray nozzle 62.

[0050] In this embodiment, Figure 3 As shown, the push protrusion 3612 extending from the outside of the rotating housing 3611 is installed in the protrusion sliding groove 351, limiting the moving path of the push protrusion 3612 and making it always extend to the outside of the moving platform 35. During the movement of the moving platform 35, if it contacts the T-shaped plates 33 on both sides, the push protrusion 3612 will contact the path groove 331 to generate displacement, and push and pull the horizontal rotating shaft 36;

[0051] In this embodiment, Figure 4 , Fig.11 As shown, during the movement of the mobile platform 35, the pushing protrusion 3612 will slide in the path groove 331 to gradually push the horizontal shaft 36, but the rotating gear 363 will still be partially engaged with the rotating rack 37 until the pushing protrusion 3612 is pushed to the limit position and the horizontal shaft 36 is completely pushed out. At this time, the rotating gear 363 will no longer be engaged with the rotating rack 37, and the lifting gear 362 will not rotate when the mobile platform 35 returns;

[0053] In this embodiment, Figure 6 , Fig.12As shown, when the mobile mounting frame 21 moves to both sides, the straight bracket 421 at the front end and the arc bracket 422 at the rear end contact the corresponding arc-shaped housing 46 when moving forward and backward respectively, and the magnetic card block 332 is magnetically attracted between the T-shaped plate 33 and the mobile mounting frame 21, and when the T-shaped plate 33 is rotated, it is clamped to prevent rotation;

[0054] In this embodiment, Figure 7 As shown, the external rotating block 42 and the internal rotating block 43 rotate synchronously, and the internal rotating block 43 and the driven rotating block 45 are connected by a rotating connecting rod 44 to form a parallel double crank structure, which rotate synchronously to drive the spray gun body 6 to rotate;

[0055] In this embodiment, Figure 8 As shown, when the mobile platform 35 drives the fixed base 51 and the rotating base 52 to move to the rotating push frame 54, the rotating push frame 54 is bent on one side, which drives the rotating base 52 to rotate around the connection with the fixed base 51, and drives the spray gun body 6 to rotate, so as to spray paint on the left side of the side of the wooden board;

[0056] In this embodiment, Fig. 9 , Fig.10 As shown, the rope fixing column 76 is rotated to wrap the connecting ropes 73 on both sides around its surface, the distance between the front clamping block 72 and the rear clamping block 721 is reduced, and the clamping paint spray nozzle 62 is deformed to change the paint spraying range.

[0057] A method for using a wood board spray painting device for waterproof cabinet processing comprises the following steps:

[0058] S1. Place the wooden board to be painted on the wooden board placement base 11, adjust the spacing of the arc-shaped housing 46 to match the front and rear dimensions of the wooden board, and adjust the spacing between the rotating push frame 54 and the T-shaped plate 33 to the other side of the T-shaped plate 33 to match the left and right dimensions of the wooden board;

[0059] S2, pull the meshing movable block 75 out from the inside of the rotating engaging seat 74, rotate the rope fixing column 76 to wrap the connecting ropes 73 on both sides around its surface, reduce the distance between the front clamping block 72 and the rear clamping block 721, clamp the paint spraying nozzle 62 to deform and change the paint spraying range, put the meshing movable block 75 into the rotating engaging seat 74 to maintain the current state, and start the spray gun body 6 and the driving motor 31;

[0060] S3, the driving motor 31 drives the threaded shaft 32 to rotate and drives the moving platform 35 to move on the moving mounting frame 21, driving the spray gun body 6 to move for spraying paint. When the moving platform 35 is close to the T-shaped plate 33 on the side of the rotating rack 37, the pushing protrusion 3612 will contact the path groove 331 to generate displacement, and push and pull the horizontal rotating shaft 36, the rotating gear 363 will still have partial meshing with the rotating rack 37, the rotating gear 363 rotates and drives the lifting gear 362 at the other end to rotate. The lifting gear 362 is partially meshed with the lifting rack 38 at this time, and the rotation is converted into direct motion while rotating, thereby driving the entire moving mounting frame 21 to move until the push When the protrusion 3612 is pushed to the limit position, the horizontal rotating shaft 36 is completely pushed out, and the rotating gear 363 will no longer mesh with the rotating rack 37. When the mobile platform 35 returns, the lifting gear 362 will not cause the mobile mounting frame 21 to move in the opposite direction due to the reversal. After moving to the front or rear end, the T-shaped plates 33 on both sides are flipped at the same time, and the path grooves 331 on the T-shaped plates 33 on both sides are also opposite. At this time, when the mobile platform 35 approaches the rotating rack 37, the rotating gear 363 will not contact the rotating rack 37, but will mesh with it when it is far away. Since the rotation direction of the rotating gear 363 and the lifting gear 362 is opposite to that before, the entire mobile mounting frame 21 is driven to move in the opposite direction.

[0061] S4, when the mobile mounting frame 21 moves to both sides, the straight bracket 421 at the front end and the arc bracket 422 at the rear end contact the corresponding arc-shaped shell 46 when moving forward and backward respectively, thereby driving the external rotating block 42 and the internal rotating block 43 to rotate synchronously. The internal rotating block 43 and the driven rotating block 45 are connected by a rotating connecting rod 44 to form a parallel double crank structure, which rotates synchronously to drive the spray gun body 6 to rotate. When the spray gun body 6 is sprayed at both sides at an angle, it can just spray paint on the side of the wooden board. When it is in the middle position, the center of gravity is downward, and the spray gun body 6 is perpendicular to the wooden board again. When the mobile platform 35 drives the fixed base 51 and the rotating base 52 to move to the rotating push frame 54, the rotating push frame 54 is bent on one side, which will push the rotating base 52 to rotate around the connection with the fixed base 51, and drive the spray gun body 6 to rotate, spray paint on the left side of the side of the wooden board, and when it is away from the rotating push frame 54, the reset spring 521 drives the fixed base 51 and the rotating base 52 to reset and return to the painting state perpendicular to the wooden board;

[0062] When the front, front and rear sides and left side are painted, the paint is dried and then turned over. At this time, the device will paint the remaining sides and the back.
