Description

Technical Field

[0001] This application relates to the technical field of spray painting equipment, and in particular to a wood spray painting equipment. Background Technology

[0002] Furniture production involves first processing wood into boards that correspond to the various parts of the furniture, and then assembling these boards into furniture. Before assembly, the boards need to be painted; the resulting paint layer enhances the boards' corrosion resistance and aesthetics.

[0003] Currently, the most common method for painting boards is manual spraying. The painting area is equipped with a spray gun and support frames to hold the boards. Before painting, the boards are placed on the spray gun, and the larger, upward-facing side of the board is sprayed. However, if the board is immediately flipped over and the opposite side painted after one side has been painted, the paint layer will come into contact with the spray gun, potentially damaging the already painted layer.

[0004] Therefore, in order to avoid damaging the painted layer when spraying the other side of the board, the board needs to be placed on a support frame and left to stand for a period of time after spraying, and then placed on the spraying rack for spraying, which is quite troublesome. Summary of the Invention

[0005] To reduce the tediousness of painting both sides of a board, this application provides a wood painting device.

[0006] This application provides a wood spray painting device, which adopts the following technical solution:

[0007] A wood spraying device includes a workbench with a mounting frame on top. A rotating shaft is rotatably connected to the mounting frame, and a mounting plate is located at the bottom of the rotating shaft. The mounting frame is equipped with a drive component for rotating the mounting plate. Multiple support columns are hinged circumferentially to the mounting plate. Support bars are rotatably connected to the support columns on the side away from the mounting plate. Clamping bars for clamping boards are symmetrically arranged on the support bars. Control components for controlling the clamping bars to move closer or further apart are provided on the support bars. The workbench has a spraying section and a painting area. The mounting plate is located between the spraying section and the painting area. The mounting plate is equipped with a drive assembly. When a support column rotates to the painting area, the drive assembly drives the support column to rotate to a vertical position. When the support column moves away from the painting area, the drive assembly drives the support column to rotate upwards to a horizontal position. A power component is located near the spraying section on the mounting frame. When the support column moves past the spraying section, the power component drives the support bars to rotate up and down.

[0008] By adopting the above technical solution, before painting, the boards are placed between two clamping strips, and the clamping strips are controlled by a control unit to hold the boards. Then, the drive unit and painting unit are activated. When the support column moves to the painting area, the drive unit drives the support column to flip downwards to a vertical position. At this time, the painting unit paints the large surface of the board. When the support column moves away from the painting area, the drive unit drives the support column to flip upwards to a horizontal position. When the support column moves away from the painting area and passes the painting unit, the power unit drives the support column to rotate, causing the large surface of the board to rotate up and down. Then, when the support column re-enters the painting area, the painting unit paints the unpainted large surface of the board. After all boards have been painted, the drive unit and painting unit can be turned off. Then, the boards are removed, dried, and the next batch of boards can be painted. The entire painting process is simple. Painting can be done on both sides of the board separately, without waiting for one side to dry before painting the other. Furthermore, the automatic flipping function during painting greatly reduces the tediousness of painting the boards.

[0009] Optionally, the drive assembly includes a drive rack and a drive bar. The drive bar is disposed on the mounting bracket and surrounds the rotation axis. The mounting plate has multiple hinge slots circumferentially. The mounting plate is rotatably connected to a hinge shaft located in the hinge slot. The support column is fixed to the hinge shaft. A drive gear is disposed on the outer periphery of the hinge shaft. The drive rack slides up and down on the mounting plate and meshes with the drive gear. The top of the drive rack slides on the bottom of the drive bar. The drive bar has a receiving groove located directly above the painting area. The drive bar forms a guide surface to guide the drive rack into and out of the receiving groove. When the drive rack slides into the receiving groove, the support column flips downward.

[0010] By adopting the above technical solution, when the drive rack slides into the receiving groove, the drive rack slides upward and the support column flips downward, so that the board is flipped to a vertical state, which is conducive to the board receiving the paint gas sprayed from the painting section on a large surface.

[0011] Optionally, the top of the drive rack is formed with an arc-shaped surface.

[0012] By adopting the above technical solution, the frictional force generated when the drive rack slides is reduced.

[0013] Optionally, the power assembly includes a power gear and a power rack. The power rack is rotatably sleeved on the outer periphery of the support column. The power gear is fixedly connected to the support bar. The power rack is located at the bottom of the mounting bracket and adjacent to the painting section. The power gear meshes with the power rack.

[0014] By adopting the above technical solution, when the support column passes through the painting section, the power rack drives the support column to rotate through the power gear, so that the plate can be flipped up and down.

[0015] Optionally, the inner peripheral sidewall of the power rack is provided with a plurality of support teeth along the circumferential direction, and the outer peripheral side of the support column is provided with one-way teeth. When the power rack drives the power gear to rotate, the one-way teeth slide unidirectionally on the support teeth.

[0016] By adopting the above technical solution, the support teeth and unidirectional teeth cooperate with each other, reducing the possibility of the support seat rotating before passing the painting section.

[0017] Optionally, the control component is a bidirectional lead screw, which is rotatably connected to the support bar. The bidirectional lead screw includes a forward rotation part and a reverse rotation part, and the clamping bar is threadedly connected to the forward rotation part and the reverse rotation part respectively.

[0018] By adopting the above technical solution, the bidirectional screw rotation can drive the two clamping bars to move closer or further apart, thereby achieving the clamping and releasing of the plate.

[0019] Optionally, the workbench is provided with a mounting base, the painting section is hinged to the mounting base, the painting section is provided with a drive column, the mounting plate is provided with a mounting ring, and the top of the mounting ring is uniformly provided with arc-shaped block-shaped drive blocks along the circumference, and the bottom of the drive column slides on the arc side of the drive block.

[0020] By adopting the above technical solution, the drive column slides on the drive block, causing the paint spraying section to rotate up and down, thereby improving the spraying range and uniformity.

[0021] Optionally, the driving component is a drive motor, which is fixed to the mounting bracket, and the output shaft of the drive motor is coaxially arranged and fixedly connected to the rotation shaft.

[0022] By adopting the above technical solution, the drive motor starts and can drive the mounting plate to rotate. The drive motor has a simple structure and is easy to use.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. During spray painting, the board is clamped between two clamping strips. Then, the drive unit drives the mounting plate to rotate, and the spray painting unit paints the large surface of the board. When the support column passes through the spray painting unit, the power unit drives the support column to rotate, causing the large surface of the board to flip up and down. There is no need to wait for the painted surface to dry before painting the other side of the large surface, which greatly reduces the tediousness of spray painting.

[0025] 2. The paint spraying section rotates up and down, greatly increasing the spraying area and reducing the possibility of uneven paint application due to concentrated spraying points. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a wood spraying device. See also: Figure 1 The wood spraying equipment includes a workbench 1, and a mounting frame 2 is provided on the top of the workbench 1. The mounting frame 2 consists of mounting columns 21 and mounting plates 22. The mounting columns 21 are symmetrically fixed on the top of the workbench 1, and the mounting plates 22 are fixed on the top of the two mounting columns 21.

[0034] See Figure 2 and Figure 3 A rotating shaft 23 is rotatably connected to the bottom center of the mounting plate 22. A disc-shaped mounting plate 3 is fixedly connected to the bottom of the rotating shaft 23, and the central axis of the mounting plate 3 coincides with the central axis of the rotating shaft 23. The mounting bracket 2 is equipped with a driving component, which is a drive motor 9. The drive motor 9 is mounted and fixed to the top of the mounting plate 22 via its own bracket, and the output shaft of the drive motor 9 is fixedly connected to the rotating shaft 23. When in use, the drive motor 9 is started, and at this time the output shaft drives the rotating shaft 23 to enter the rotation state.

[0035] See Figure 3 The mounting plate 3 has multiple hinge slots 34 evenly spaced along its circumference on its outer periphery. A cylindrical hinge shaft 341 is rotatably connected to the mounting plate 3. The hinge shaft 341 corresponds to and is located within each hinge slot 34. A support column 31 is fixedly connected to the outer periphery of the hinge shaft 341. The support column 31 extends away from the mounting plate 3 and can be rotated up and down during use.

[0036] See Figure 3 A support bar 32 is rotatably connected to the side of the support column 31 away from the mounting plate 3. A groove is opened on the side of the support bar 32 away from the support column 31. Two clamping bars 33 are symmetrically arranged on the support bar 32. The clamping bars 33 slide in the groove. Before painting, the board is placed between the clamping bars 33. The two clamping bars 33 cooperate with each other to clamp the board, so that when the support column 31 is flipped to the vertical position, the large surface of the board is parallel to the central axis of the rotating shaft 23.

[0037] See Figure 3 and Figure 4 The support bar 32 is equipped with a control element for controlling the clamping bars 33 to move closer or further apart, facilitating the clamping bars 33 to clamp or release the sheet material. The control element is a bidirectional lead screw 4, which is rotatably connected to the support bar 32 and located within a groove. The bidirectional lead screw 4 includes a forward rotation part 42 and a reverse rotation part 41, with the two clamping bars 33 threadedly connected to the forward rotation part 42 and the reverse rotation part 41, respectively. When the bidirectional lead screw 4 rotates, the two clamping bars 33 simultaneously move closer or further apart.

[0038] See Figure 1 A mounting base 11 is fixedly connected to the workbench 1, and a spraying section 5, which is a spray gun, is mounted on the mounting base 11. The spray gun is connected to an external paint source. During spraying, the external paint source transmits pressurized paint gas to the spray gun, which then sprays the paint gas onto the board. A painting area 6 is also provided on the workbench 1. The mounting plate 3 is located between the painting area 6 and the spray gun. The paint gas sprayed by the spray gun towards the painting area 6 paints the board between the spray gun and the painting area 6.

[0039] See Figure 1 and Figure 3The mounting plate 22 is equipped with a drive assembly 7 for controlling the vertical rotation of the support column 31. The drive assembly 7 includes a drive rack 71 and a drive bar 72. The mounting plate 3 has a drive hole that connects to the hinge slot 34, and the drive rack 71 slides up and down in the drive hole. A drive gear 342 is fixedly connected to the outer periphery of the hinge shaft 341, and the drive rack 71 meshes with the drive gear 342. In use, the drive rack 71 slides up and down to drive the hinge shaft 341 to rotate. The drive bar 72 is fixed to the bottom of the mounting plate 22 and surrounds the rotation shaft 23. The top of the drive bar 72 has an arc-shaped surface 711 with an arc structure. In the initial state, the arc-shaped surface 711 abuts against the bottom of the drive bar 72, at which time the support column 31 is rotated upward to a horizontal state. The bottom of the drive bar 72 has a receiving groove 721 located in the painting area 6. The drive bar 72 has symmetrically arranged guide surfaces 722. The drive rack 71 slides into and out of the receiving groove 721 through the two guide surfaces 722. When the drive rack 71 slides from the drive bar 72 into the receiving groove 721 through the guide surfaces 722, under the gravity of the support column 31 and the plate, the drive gear 342 drives the drive rack 71 to slide upward. At this time, the drive rack 71 gradually enters the receiving groove 721 along the guide surfaces 722, while the support column 31 begins to rotate downward until the drive rack 71 abuts against the groove wall of the receiving groove 721 near the mounting plate 3. At this time, the support column 31 is in a vertical state. With the rotating shaft 23 as the center, the support column 31 between the painting area 6 and the spray gun is in a horizontal state. Therefore, the paint sprayed from the spray gun can directly paint the large surface of the plate in the vertical state of the painting area 6. When the support column 31 leaves the painting area 6, the drive rack 71 slides out of the receiving groove 721 through the guide surface 722. At this time, the support column 31 flips to a horizontal state, so that the paint layer on the large surface of the board can be in a relatively uniform state.

[0040] See Figure 1 and Figure 3 To improve the uniformity of paint application on the substrate, the spray gun is hinged to the mounting base 11, allowing the spray gun to rotate up and down. A drive column 51 is fixedly connected to the bottom of the spray gun. A fixing column 35 is symmetrically fixed to the bottom of the mounting plate 3, and a fixing strip 36 is fixed to the bottom of the fixing column 35. The mounting plate 3 has a mounting ring 37, with the end of the fixing strip 36 away from the fixing column 35 fixed to the mounting ring 37. The diameter of the mounting ring 37 is larger than that of the mounting plate 3. The drive column 51 is located directly above the mounting ring 37. Multiple drive blocks 38 are evenly fixed to the top of the mounting ring 37 along its circumference. The drive blocks 38 are arc-shaped blocks with their convex sides facing upwards, and adjacent drive blocks 38 are interconnected. A hemispherical frame-shaped slider is located at the bottom of the drive column 51, sliding along the drive blocks 38. When the mounting plate 3 rotates, the slider slides along the convex side of the drive blocks 38, allowing the spray gun to rotate up and down, improving the spraying range and effect.

[0041] See Figure 4 and Figure 5 The mounting plate 3 is equipped with a power component 8. When the mounting plate 3 rotates, it drives the support column 31 to move from the painting area 6 to the spray gun and pass through the spray gun. The power component 8 drives the support bar 32 to flip up and down, so that the board flips from the bottom to the top after passing through the painting side.

[0042] See Figure 4 and Figure 5 The power assembly 8 includes a power gear 81 and a power rack 82. The power gear 81 has a support hole 821 through which the support column 31 passes, allowing the power gear 81 to rotate and be fitted onto the outer periphery of the support column 31. The rotating gear is also fixedly connected to the support bar 32. The power rack 82 extends along an arc trajectory and is fixed to the bottom of the mounting plate 22. The power rack 82 is located above the spray gun, and the power gear 81 meshes with the power rack 82. When the mounting plate 3 rotates until the support column 31 passes the spray gun, the power rack 82 and the power gear 81 engage. At this time, the power rack 82 drives the rotating shaft 23 to rotate through the power gear 81, causing the support bar 32 to flip up and down, thus completing the flipping of the plate.

[0043] See Figure 4 and Figure 5 To reduce the possibility of the support bar 32 rotating before passing the spray gun, support teeth 822 are uniformly fixedly connected circumferentially to the sidewall of the support hole 821 of the power gear 81. One-way teeth 311 are fixedly connected to the outer periphery of the support column 31. The one-way teeth 311 are located inside the support hole 821, and both the one-way teeth 311 and the support teeth 822 can be made of a material with a certain degree of elasticity, such as plastic. When the support column 31 rotates as it passes the spray gun, the one-way teeth 311 slide unidirectionally against the support teeth 822; when the mounting plate 3 rotates in the opposite direction, causing the support column 31 to move upwards from the spray gun towards the paint area 6, the support teeth 822 unidirectionally support the one-way teeth 311. In use, the one-way tooth 311 and the support tooth 822 cooperate with each other. When the force on the support column 31 is less than the force required for the one-way tooth 311 to slide in one direction on the support tooth 822, the support column 31 can maintain a state of restricted rotation. At the same time, the support tooth 822 supports the one-way tooth 311 in one direction, restricting the reverse rotation of the mounting plate 3 and reducing the possibility of excessive paint layer caused by repeated painting of the board surface.

[0044] The implementation principle of a wood spraying device according to an embodiment of this application is as follows:

[0045] Before painting, the panels are clamped between the two clamping strips 33 of each support strip 32. Then, the drive motor 9 and spray gun are started. When the support column 31 moves to the painting area 6, the support column 31 flips downward to a vertical position. At this time, the spray gun paints the large surface of the vertical panel. When the support column 31 begins to move away from the painting area 6, the support column 31 flips upward to a horizontal position. When the support column 31 passes over the spray gun, it rotates, causing the panel to flip up and down. At this time, the painted surface of the panel flips from bottom to top. Then, the mounting plate 3 continues to rotate until it moves to the painting area 6 again. The support column 31 flips downward, causing the spray gun to paint the unpainted surface of the panel. After all the panels on the mounting plate 22 have been painted, the drive motor 9 and spray gun can be turned off. The panels can then be removed and leaned against the wall to dry. The whole process is simple. There is no need to wait for the painted side to dry before painting the opposite side. The paint automatically flips and adjusts the painted surface during the painting process, which greatly reduces the tediousness of painting.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
