Description

Technical Field

[0001] This utility model relates to the field of solid wood board surface treatment technology, specifically to an upper and lower surface treatment device for solid wood board processing. Background Technology

[0002] In the field of solid wood board processing, applying paint to the top, bottom, and sides of the board is a key process to improve the board's performance in terms of moisture resistance, wear resistance, and aesthetics. Currently, the solid wood board surface treatment equipment on the market still has some shortcomings in practical applications.

[0003] Existing spraying equipment often uses nozzles with fixed angles, resulting in localized accumulation or uneven distribution of paint on the surface of the board. This often requires manual re-spraying for touch-ups, which is not only inefficient but also prone to problems such as inconsistent thickness and incomplete edge coverage. Even if some equipment is equipped with side nozzles, the fixed nozzle angle still results in poor coverage, leading to paint waste and increased production costs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an upper and lower surface treatment device for solid wood board processing, which solves the problems of incomplete coverage caused by the fixed nozzle angle in traditional solid wood board surface spraying structures.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A surface treatment device for solid wood board processing includes: a conveying structure, with a spraying structure fixedly connected to the inner wall of the conveying structure; the spraying structure includes a three-way connector, with connecting pipes symmetrically fixedly connected to the outer wall of the three-way connector, a spray pipe fixedly connected to the inner wall of the connecting pipe, a first nozzle slidably connected to the outer wall of the top of the spray pipe, a branch pipe fixedly connected to the inner wall of the side of the first nozzle, a second nozzle fixedly connected to the outer wall of the branch pipe, a connecting ring fixedly connected to the inner wall of the first nozzle, a ball bearing rotatably connected to the inner wall of the connecting ring, and an annular groove formed on the outer wall of the spray pipe.

[0009] Preferably, the nozzles are arranged laterally along the inner wall of the connecting pipe, and the branch pipes are arranged in a ring array along the central point of the first nozzle, and the branch pipes are set at an angle.

[0010] Preferably, the outer wall of the connecting ring is slidably connected to the inner wall of the ring groove, and the outer wall of the ball is slidably connected to the inner wall of the ring groove. When the paint is sprayed out through the second nozzle on the branch pipe, the sprayed force will act on the first nozzle through the branch pipe. Through the cooperation of the ball and the ring groove, the applied force will push the first nozzle to rotate along the spray pipe.

[0011] Preferably, the conveying structure includes a base, a conveyor is symmetrically and fixedly connected to the outer wall of the top of the base, a protective frame is fixedly connected to the outer wall of the top of the base, a conveying roller is symmetrically and rotatably connected to the inner wall of the protective frame, a conveying wheel is fixedly connected to the outer wall of the conveying roller, and an anti-slip pad is fixedly connected to the outer wall of the conveying wheel.

[0012] Preferably, a drive motor is connected to the outer wall of the conveying roller, and the conveying wheels are arranged laterally along the outer wall of the conveying roller. The solid wood board is conveyed into the protective frame by the conveyor. The drive motor is connected to the outer wall of the conveying roller. After the motor starts, it drives the conveying roller to rotate, which in turn drives the conveying wheels fixed to the outer wall of the conveying roller to rotate synchronously, thus conveying the solid wood board.

[0013] Preferably, the outer wall of the connecting pipe is fixedly connected to the inner wall of the protective frame, and the connecting pipe is located in the middle of the symmetrical conveying rollers. The protective frame at the top of the base forms a closed processing space to prevent paint from splashing.

[0014] (III) Beneficial Effects

[0015] This utility model provides a device for treating the upper and lower surfaces of solid wood boards. It has the following beneficial effects:

[0016] (i) The spraying structure directly covers the upper and lower main surfaces of the board through the first nozzle, and the ring array of branch pipes and the second nozzle expands the treatment of the board surface, which solves the problem of uneven coating of traditional equipment and achieves full coverage of the board surface without dead corners. The reaction force of the paint spraying pushes the first nozzle to rotate along the spray pipe, so that the paint forms a dynamic coverage on the board surface, avoiding local accumulation or missed coating caused by the fixed nozzle due to the single angle, thus improving the uniformity of coating.

[0017] (ii) The conveying structure increases the friction between the conveying wheel and the solid wood board through the anti-slip pad on the outer wall of the conveying wheel. Combined with the stable output of the drive motor, it effectively prevents the board from slipping or deviating during the conveying process, ensuring that the board always passes through the spraying area along the preset path. The protective frame forms a closed processing space, avoiding environmental pollution caused by paint splashing. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a surface treatment device for solid wood board processing, comprising: a conveying structure 1, a spraying structure 2 fixedly connected to the inner wall of the conveying structure 1; the spraying structure 2 includes a three-way connector 21, a connecting pipe 22 symmetrically fixedly connected to the outer wall of the three-way connector 21, a spray pipe 23 fixedly connected to the inner wall of the connecting pipe 22, a first nozzle 24 slidably connected to the outer wall of the top of the spray pipe 23, a branch pipe 25 fixedly connected to the inner wall of the side of the first nozzle 24, a second nozzle 26 fixedly connected to the outer wall of the branch pipe 25, a connecting ring 27 fixedly connected to the inner wall of the first nozzle 24, a ball bearing 28 rotatably connected to the inner wall of the connecting ring 27, and an annular groove 29 formed on the outer wall of the spray pipe 23.

[0026] The nozzles 23 are arranged laterally along the inner wall of the connecting pipe 22, and the branch pipes 25 are arranged in a ring along the central point of the first nozzle 24, and the branch pipes 25 are set at an angle.

[0027] The outer wall of the connecting ring 27 is slidably connected to the inner wall of the ring groove 29, and the outer wall of the ball 28 is slidably connected to the inner wall of the ring groove 29. When the paint is sprayed out through the second nozzle 26 on the branch pipe 25, the spraying force will act on the first nozzle 24 through the branch pipe 25. Through the cooperation of the ball 28 and the ring groove 29, the applied force will push the first nozzle 24 to rotate along the spray pipe 23.

[0028] The conveying structure 1 includes a base 11, a conveyor 12 is symmetrically and fixedly connected to the outer wall of the top of the base 11, a protective frame 13 is fixedly connected to the outer wall of the top of the base 11, a conveying roller 14 is symmetrically and rotatably connected to the inner wall of the protective frame 13, a conveying wheel 15 is fixedly connected to the outer wall of the conveying roller 14, and an anti-slip pad 16 is fixedly connected to the outer wall of the conveying wheel 15.

[0029] A drive motor is connected to the outer wall of the conveyor roller 14. The conveyor wheels 15 are arranged laterally along the outer wall of the conveyor roller 14. The solid wood boards are conveyed into the protective frame 13 by the conveyor 12. The drive motor is connected to the outer wall of the conveyor roller 14. After the motor starts, it drives the conveyor roller 14 to rotate, which in turn drives the conveyor wheels 15 fixed on the outer wall of the conveyor roller 14 to rotate synchronously, thus conveying the solid wood boards.

[0030] The outer wall of the connecting pipe 22 is fixedly connected to the inner wall of the protective frame 13, and the connecting pipe 22 is located in the middle of the symmetrical conveying rollers 14. The protective frame 13 at the top of the base 11 forms a closed processing space to prevent paint from splashing.

[0031] In use, the solid wood board to be processed is continuously conveyed by the conveying power of the conveying structure 1. When it passes through the processing area of ​​the spraying structure 2, the spraying structure 2 sprays paint onto the upper and lower surfaces of the board simultaneously through multi-directional nozzles.

[0032] Solid wood boards are placed on conveyor 12. The protective frame 13 on the top of the base 11 forms a closed processing space to prevent paint from splashing. The solid wood boards are conveyed into the protective frame 13 by conveyor 12. The outer wall of the conveyor roller 14 is connected to a drive motor. After the motor starts, it drives the conveyor roller 14 to rotate, which in turn drives the conveyor wheel 15 fixed on the outer wall of the conveyor roller 14 to rotate synchronously. The solid wood boards come into contact with the symmetrically distributed conveyor wheels 15. When the conveyor wheels 15 rotate, the anti-slip pads 16 on the outer wall can increase the friction with the surface of the board. The friction drives the board to move along the conveying direction, avoiding slippage and ensuring stable conveying speed.

[0033] The external paint supply system diverts paint to symmetrical connecting pipes 22 via a three-way connector 21. The connecting pipes 22 guide the paint into the horizontally arranged spray pipes 23, achieving uniform paint distribution. The first nozzle 24 on the spray pipe 23 is directly aimed at the upper and lower surfaces of the board. Paint is sprayed from the first nozzle 24, covering the main surface of the board. The branch pipes 25 on the side of the first nozzle 24 are arranged in a ring array along the axis of the first nozzle 24 and are inclined. When the paint is sprayed out through the second nozzle 26 on the branch pipe 25, the spraying force will act on the first nozzle 24 through the branch pipe 25. Since the first nozzle 24 is slidably connected to the annular groove 29 on the outer wall of the spray pipe 23 through the connecting ring 27, and the ball bearing 28 on the inner wall of the connecting ring 27 is slidably engaged with the annular groove 29, the applied force will push the first nozzle 24 to rotate along the spray pipe 23, increasing the spraying range and improving the uniform coverage of the paint, thus avoiding missed areas.
