Description

Technical Field

[0001] This utility model relates to the technical field of painting devices, specifically a wood surface painting device for wood processing. Background Technology

[0002] Timber processing refers to the process of using timber as raw material and processing raw timber (such as logs) into wood products or semi-finished products with specific shapes, sizes, properties, or uses through mechanical, physical, and chemical means. It is a crucial link in the forestry industry, connecting timber resources with downstream applications (such as construction, furniture, decoration, and papermaking). A type of timber processing wood surface painting device is used to apply paint to the surface of timber (such as planks, timber squares, and timber components) to achieve functions such as corrosion prevention, aesthetics, and protection.

[0003] In existing technologies, existing painting devices are inconvenient for cleaning waste materials on the surface of wood boards during painting. Wood chips, wood dust, and other waste materials remaining from the early processing of wood (such as sawing and sanding) will adhere to the surface. During painting, these waste materials will be coated by the paint, forming bumps, particles, or spots, resulting in a significant decrease in the smoothness of the paint surface and even the risk of local peeling. At the same time, the gaps between the waste materials and the surface of the wood board will be filled by the paint, preventing the paint from making full contact with the wood board itself, greatly weakening the adhesion of the paint film. In subsequent use, it is easy for the wood board to peel or crack due to slight collisions or friction, affecting the anti-corrosion and moisture-proof performance of the wood board and shortening the service life of the wood products. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides an embodiment of a wood surface painting device for wood processing, including a base 1, a height adjustment frame 21 disposed on the base 1, a height adjustment component disposed between the height adjustment frame 21 and the base 1, a movable frame 22 slidably connected inside the height adjustment frame 21, a drive component disposed on the height adjustment frame 21 and the movable frame 22, a painting component disposed on the movable frame 22, a drying component disposed on the movable frame 22, a rotating disk 23 rotatably connected to the movable frame 22, a smooth rod 25 fixedly connected to the rotating disk 23, a movable bracket 26 rotatably connected at one end to the smooth rod 25, a swing frame 27 rotatably connected inside the movable frame 22, and a fixed connection. The optical shaft 28 on the swing frame 27 and the cleaning brush 29 fixedly connected to the bottom of the swing frame 27 are connected to the optical shaft 28 at the other end of the movable bracket 26. The drive component is used to drive the movable frame 22 to move in the vertical direction and to drive the cleaning brush 29 to swing back and forth. When the painting component is painting the wood board, the drive component drives the rotating disk 23 to rotate, and the movable bracket 26 drives the swing frame 27 to swing back and forth on the movable frame 22. This allows the cleaning brush 29 fixed at the bottom of the swing frame 27 to clean the unpainted area of ​​the wood board, effectively removing surface impurities and preventing impurities from being covered by paint to form defects such as bumps and particles, thereby improving the smoothness of the paint surface and the adhesion of the paint film.

[0024] Please see Figure 1A further solution based on this embodiment is as follows: the height adjustment frame 21 has a sliding groove at the corresponding position of the movable frame 22, and the movable frame 22 is slidably connected inside the sliding groove of the height adjustment frame 21. Through the sliding cooperation between the sliding groove on the height adjustment frame 21 and the movable frame 22, a stable guide trajectory is provided for the vertical movement of the movable frame 22, effectively preventing the movable frame 22 from deviating or shaking during the movement, ensuring that the painting assembly, drying assembly and cleaning brush 29 and other components can always be accurately aligned with the surface of the wooden board, improving the stability and consistency of the operation.

[0025] Please see Figure 1-2 A further solution based on this embodiment is as follows: the driving component includes a second motor 210 fixedly connected to one side of the height adjustment frame 21, a threaded rod 211 rotatably connected inside the height adjustment frame 21, and a first motor 24 fixedly connected to the movable frame 22. The rotating disk 23 is fixedly connected to the output end of the first motor 24, the threaded rod 211 is fixedly connected to the output end of the second motor 210, and the movable frame 22 is threadedly connected to the outside of the threaded rod 211. The second motor 210 drives the threaded rod 211 to rotate, and the threaded transmission drives the movable frame 22 to move smoothly in the vertical direction, thereby achieving precise control of the height of the painting component and the drying component. At the same time, the first motor 24 directly drives the rotating disk 23 to rotate, providing stable power for the reciprocating oscillation of the cleaning brush 29, ensuring the continuity and efficiency of the cleaning action. The two motors have clear division of labor, which improves the overall driving accuracy and reliability of the device.

[0026] Please see Figure 2-3 A further embodiment of this design includes: a painting assembly comprising a storage frame 31 fixedly connected to a height adjustment frame 21, a feed inlet 32 ​​fixedly connected to the storage frame 31, a water pump 33 fixedly connected to the height adjustment frame 21, a draw tube 34 fixedly connected between the draw tube 34 and the storage frame 31, a rolling brush 37 rotatably connected inside the height adjustment frame 21, a paint outlet frame 35 fixedly connected to the side of the height adjustment frame 21 with the rolling brush 37, and a paint outlet frame 35 fixedly connected between the water pump 33 and the paint outlet frame 35. The conveying pipe 36 stores paint through the storage frame 31, and the inlet 32 ​​allows for timely replenishment of paint, ensuring a continuous supply of paint. The water pump 33 draws paint from the storage frame 31 through the extraction pipe 34, and then conveys it to the paint outlet frame 35 through the conveying pipe 36. Finally, the paint outlet frame 35 evenly drips the paint onto the rolling brush 37. When the rolling brush 37 rotates, it can evenly coat the wood surface with paint. The entire paint delivery and coating process is continuous and efficient, reducing paint waste and ensuring uniform paint thickness, thus improving the quality of painting.

[0027] Please see Figure 3A further solution based on this embodiment is as follows: a number of sets of paint nozzles are provided on the side of the paint outlet frame 35 near the roller brush 37, and the number of sets of paint nozzles are symmetrically distributed on the paint outlet frame 35. Through the number of sets of paint nozzles symmetrically distributed on the paint outlet frame 35, the paint can be sprayed more evenly on the surface of the roller brush 37, avoiding the situation where there is too much or too little paint in some places on the roller brush 37, ensuring that when the roller brush 37 comes into contact with the wood, each part can carry an appropriate amount of paint, thereby making the paint surface of the wood surface smoother and more even, and further improving the consistency of the painting effect.

[0028] Please see Figure 4 A further solution based on this embodiment is as follows: The drying component includes a fixed frame 41 fixedly connected to the side of the movable frame 22 and the second motor 210, a blower 42 fixedly connected to the inside of the fixed frame 41, and an electric heating tube 43 fixedly connected to the inside of the fixed frame 41. Heat is generated by the electric heating tube 43, and the blower 42 blows the heat evenly onto the surface of the freshly painted wood, forming a continuous and stable hot air drying environment. This can quickly accelerate the drying speed of the paint, avoid problems such as scratches and dust contamination caused by the paint not being dry, shorten the processing cycle, and at the same time ensure the hardness and adhesion of the paint surface after drying, reducing the risk of paint surface damage in the later stage.

[0029] Please see Figure 5 A further embodiment of this solution is as follows: The height adjustment assembly includes a placement frame 51 fixedly connected to the base 1, an anti-slip pad 52 fixedly connected to the placement frame 51, an outer frame 53 fixedly connected to the base 1, a hydraulic telescopic rod 55 fixedly connected to the base 1, and a sliding inner rod 54 slidably connected inside the outer frame 53. The height adjustment frame 21 is fixedly connected to the telescopic end of the hydraulic telescopic rod 55, and the sliding inner rod 54 is fixedly connected to the height adjustment frame 21. The hydraulic telescopic rod 55 is used to drive the height adjustment frame 21 to adjust up and down. The hydraulic telescopic rod 55 provides a strong and stable driving force to drive the height adjustment frame 21 to move up and down, realizing a wide range of adjustment of the working height of the entire device to adapt to the processing needs of different specifications of wood. The placement frame 51 and the anti-slip pad 52 provide a stable placement platform for the wood and prevent the wood from sliding during processing. The cooperation between the outer frame 53 and the sliding inner rod 54 provides guidance and support for the movement of the height adjustment frame 21, enhancing the stability and safety of the device during the height adjustment process.

[0030] Please see Figure 5A further solution based on this embodiment is as follows: the outer frame 53 has a groove at the corresponding position of the sliding inner rod 54, and the sliding inner rod 54 is slidably connected inside the groove of the outer frame 53. Through the sliding cooperation between the groove on the outer frame 53 and the sliding inner rod 54, the movement trajectory of the sliding inner rod 54 is further restricted, so that the height adjustment frame 21 can only move smoothly in the vertical direction under the drive of the hydraulic telescopic rod 55, avoiding lateral deviation or swaying, ensuring the accuracy of the height adjustment process, and reducing frictional wear between components, thus extending the service life of the device.

[0031] Working principle: First, the wooden board is placed on the placement rack 51 of the height adjustment component, and the anti-slip pad 52 prevents the board from sliding. Then, the height adjustment frame 21 is driven to move up and down by the hydraulic telescopic rod 55 of the height adjustment component. The outer frame 53 and the sliding inner rod 54 slide along the slide groove to adjust the overall working height of the device to fit the thickness of the wooden board. Next, the second motor 210 of the drive component drives the threaded rod 211 to rotate, so that the moving frame 22 moves vertically along the slide groove of the height adjustment frame 21 and moves to the left. At this time, the first motor 24 drives the rotating disk 23 to rotate, and the smooth rod 25 rotates with the rotating disk 23 and drives the smooth shaft 28 on the swing frame 27 to move through the movable bracket 26, so that the swing frame 27 moves. The frame 27 swings back and forth, allowing the cleaning brush 29 to clean the unpainted areas of the wooden board and remove surface impurities. Then, the paint in the storage box 31 is replenished through the feed port 32, and the water pump 33 draws out the paint through the extraction pipe 34 and sends it to the paint outlet frame 35 through the delivery pipe 36. The paint is then evenly dripped onto the rolling brush 37 by the symmetrically distributed paint outlets. The rolling brush 37 rotates to paint the cleaned wooden board surface. Heat is generated by the electric heating tube 43 and blown onto the paint surface by the fan 42 to achieve rapid drying and ensure the quality of the paint surface. Throughout the process, the moving frame 22 moves from right to left to perform a continuous operation of cleaning, painting and drying the wooden board surface, which efficiently improves the painting effect.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
