Description

Technical Field

[0001] This utility model belongs to the field of coating technology, and in particular relates to a coating device for anti-corrosion wood. Background Technology

[0002] Coating is a material protection technology that uses paint to form an organic coating on the surface of a substrate material. Coating is an important part of the surface manufacturing process of engineering machinery products. The quality of rust-proof and corrosion-proof coating is one of the important aspects of the overall quality of the product. The appearance quality of the product not only reflects the protective and decorative performance of the product, but is also an important factor in the value of the product.

[0003] According to the authorized patent application CN220111443U, a fully automatic anti-corrosion wood coating device includes a main frame. A linkage component is installed on the inner wall of the main frame, and a spray pipe is installed on the inner wall of the linkage component. A slide is slidably connected to the inner wall of the main frame. A second hydraulic rod is fixedly connected to the outer wall of the slide, and a third hydraulic rod is fixedly connected to the outer wall of the slide. A scraper is fixedly connected to the outer wall of the third hydraulic rod. An auxiliary support plate is installed on the outer wall of the main frame, and a base bed assembly is installed on the outer wall of the support plate. A discharge chute is opened on the right side of the main frame. The base bed assembly includes a support rod installed on the inner wall of the main frame. A movable block is installed at one end of the support rod. A bearing plate is fixedly connected to the outer wall of the movable block. An insert plate is inserted into the inner wall of the bearing plate. A hydraulic cylinder is movably connected to the bottom of the bearing plate through the movable block. A nozzle is installed at the discharge end of the spray pipe, and a control valve is installed on the outer wall of the spray pipe. A fixing hole is opened on the bottom inner wall of the main frame, and a drainage hole is opened at the end of the bearing plate. This coating device has a good coating effect, but it still has the following problems, such as:

[0004] The current anti-corrosion wood coating device only uses a nozzle and control valve to apply the coating to the wood, and then uses a scraper to apply it. Since only one set of scrapers is set, it is impossible to coat all four sides of the wood, resulting in waste of coating. Therefore, we propose an anti-corrosion wood coating device. Utility Model Content

[0005] The purpose of this utility model is to provide a coating device for preservative-treated wood, which solves the problem of uneven coating in existing preservative-treated wood coating devices by using a coating box.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a coating device for anti-corrosion wood, comprising a coating scraper rotatably connected to the inner wall of a coating box, of which two scrapers are provided. The outer surface of each scraper contains identical parts. A connecting block is fixedly connected to the outer wall of the scraper, and a fixing rod is fixedly connected to the inner wall of the connecting block. A rotating block is rotatably connected to the outer surface of the fixing rod. A spring is fixedly connected to the end of the rotating block away from the fixing rod, and a telescopic rod is fixedly connected to the end of the rotating block away from the fixing rod. The outer surface of the telescopic rod is sleeved with the inner wall of the spring. The end of the spring away from the rotating block is fixedly connected to the rotating block. The right side of the telescopic rod is fixedly connected to the left side of the rotating block. The inner wall of the rotating block is rotatably connected to the fixing rod. The outer surface of the fixing rod is fixedly connected to the connecting block. The right side of the connecting block is fixedly connected to the inner wall of the coating box. By squeezing the spring and the telescopic rod, the spring has a rebound effect, so that the coating scraper is pressed tightly against the wooden board, thereby enabling the coating to be completed on all four sides of the wooden board. The spring and the telescopic rod will keep the coating scraper pressed tightly against the wooden board, achieving a more uniform coating effect.

[0008] Furthermore, the inner wall of the coating box is rotatably connected to four rotating columns. The outer surfaces of the rotating columns contain identical parts. A second coating scraper is fixedly connected to one side of each rotating column that is close to the other. A third connecting block is fixedly connected to the outer wall of the second coating scraper. A third rotating block is rotatably connected to the inner wall of the third connecting block. A second spring is fixedly connected to the outer wall of the third rotating block. A second telescopic rod is fixedly connected to the outer wall of the third rotating block. The inner wall of the second spring and the outer surface of the second telescopic rod are fitted together. The rotating columns, which can rotate on the coating box, allow the second coating scraper to rotate, thus facilitating the wooden board to push the second coating scraper away.

[0009] Furthermore, a rotating block four is fixedly connected to the end of the spring two away from the rotating block three, the bottom of the telescopic rod two is fixedly connected to the top of the rotating block four, a connecting block four is rotatably connected to the bottom of the rotating block four, and the bottom of the connecting block four is fixedly connected to the inner wall of the coating box. Through the cooperation of the rotating block and the connecting block, the effect of facilitating the rotation of the coating scraper is achieved.

[0010] Furthermore, a motor is installed on the left side of the coating box, and a fixing frame is fixedly connected to the outer surface of the motor. The right side of the fixing frame is fixedly connected to the left side of the coating box. The bottom output shaft of the motor is fixedly connected to a drive rod through a coupling. The right side of the drive rod passes through the coating box and extends into its interior. A pulley is fixedly connected to the outer surface of the drive rod. A belt is drivenly connected to the outer surface of the pulley. A pulley is drivenly connected to the end of the belt away from the pulley. Through the cooperation of the belt and the pulleys, the rotating cylinder can be easily rotated, thereby feeding the wooden board into the device.

[0011] Furthermore, a rotating cylinder is fixedly connected to the inner wall of the second pulley, a connecting rod is rotatably connected to the inner wall of the first rotating cylinder, a slider is fixedly connected to the left side of the connecting rod, a groove is provided on the inner wall of the coating box, the outer surface of the slider is fixedly connected to the inner wall of the groove, a second slider is slidably connected to the inner wall of the groove, a connecting rod is fixedly connected to the right side of the second slider, and a rotating cylinder is rotatably connected to the outer surface of the connecting rod. By using the slider that slides inside the groove, the position of the first and second rotating cylinders is restricted.

[0012] Furthermore, a threaded cylinder is fixedly connected to the right side of the connecting rod one. There are two threaded cylinders in total. The right side of the connecting rod two is fixedly connected to the left side of the threaded cylinder. A threaded rod is rotatably connected to the inner wall of the top threaded cylinder. The inner wall of the bottom threaded cylinder is threadedly connected to the outer surface of the threaded rod. The top of the threaded rod is rotatably connected to the inner wall of the coating box. A bevel gear two is fixedly connected to the bottom of the threaded rod. A bevel gear one meshes with the outer surface of the bevel gear two. An adjusting rod is fixedly connected to the right side of the rotating block three. The adjusting rod passes through the coating box on the right and extends to the outside. A rotating handle is fixedly connected to the right side of the adjusting rod. A collection box is fixedly connected to the bottom of the coating box. By adjusting the bevel gear one driven by the rotating rod, the threaded rod is rotated, so that the rotating cylinder one and the rotating cylinder two can move closer or further apart. The size can be adjusted according to the thickness of the wood board. Then, the rotating cylinder one and the rotating cylinder two not only clamp the wood board, but also work with the motor to achieve the effect of slowly feeding the wood board into the coating scraper one inside the device.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, by setting up a coating box, allows the coating scraper to be pushed open by the wooden board, enabling it to coat the wood on both sides. During the process of the coating scraper being pushed open, the connecting block moves along with it. The movement of the connecting block causes the rotating block to rotate on the connecting block via the fixing rod. Simultaneously, the rotating block rotates on the connecting block via the fixing rod, thereby compressing the spring and the telescopic rod. By compressing the spring and the telescopic rod, a rebound effect is achieved, keeping the coating scraper pressed tightly against the wooden board. This ensures that all four sides of the wooden board can be coated, and the spring and the telescopic rod keep the coating scraper pressed against the wooden board, resulting in a more uniform coating effect.

[0015] 2. This utility model, by setting up rotating cylinder one and rotating cylinder two, rotates the handle, which drives the adjusting rod to rotate, thereby rotating bevel gear one. The rotation of bevel gear one, in turn, causes the threaded rod to rotate through bevel gear two. Since the upper and lower threads on the threaded rod are opposite, the threaded cylinders move closer or further apart. By adjusting the bevel gear one driven by the adjusting rod, the rotation of the threaded rod is driven, thereby allowing rotating cylinder one and rotating cylinder two to move closer or further apart. The size can be adjusted according to the thickness of the wooden board. Then, rotating cylinder one and rotating cylinder two not only clamp the wooden board, but also work with the motor to achieve the effect of slowly feeding the wooden board into the coating scraper one inside the device.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The right side of the 212 extends through the coating box 2 and outwards. A rotating handle 213 is fixedly connected to the right side of the adjusting rod 212. A collection box 217 is fixedly connected to the bottom of the coating box 2. By adjusting the bevel gear 211 driven by the adjusting rod 212, the threaded rod 220 is rotated, thereby allowing the rotating cylinder 207 and the rotating cylinder 216 to move closer or further apart. The size can be adjusted according to the thickness of the wood board. The rotating cylinder 207 and the rotating cylinder 216 not only clamp the wood board, but also work with the motor 201 to slowly feed the wood board into the coating scraper 1 inside the device.

[0036] A specific application of this embodiment is as follows: When using this device, firstly, adjust the distance between rotating cylinder 1 207 and rotating cylinder 216 according to the required thickness of the wood to be coated. This can be adjusted by rotating the handle 213. Rotating the handle 213 will drive the adjusting rod 212 to rotate, thereby rotating the bevel gear 1 211. The rotation of bevel gear 1 211 will cause the threaded rod 220 to rotate through bevel gear 219. By adjusting the bevel gear 1 211 driven by the adjusting rod 212, the threaded rod 220 is driven to rotate, thereby allowing rotating cylinder 1 207 and rotating cylinder 216 to move closer or further apart. The size can be adjusted according to the thickness of the wood. Then, rotating cylinder 1 207 and rotating cylinder 216 not only coat the wood... The plate acts as a clamp and, in conjunction with motor 201, slowly feeds the wooden board into the coating scraper 1 inside the device. This allows the threaded cylinder 218 to adjust the positions of rotating cylinders 216 and 207 via connecting rods 215 and 208. When connecting rods 208 and 215 move up and down, slider 209 remains stationary within the groove 210, while slider 214 slides within the groove 210. Once rotating cylinders 207 and 216 are in the appropriate positions, motor 201 is activated. The position of motor 201 is fixed by the bracket 202, preventing it from rotating on its own. Motor 201 causes the drive rod 203 to rotate, driving pulley 204 to rotate as well. 4. Belt 205 drives pulley 206 to rotate, which in turn drives rotating cylinder 207 to rotate. Then, the wooden board is placed in the gap between rotating cylinder 207 and rotating cylinder 216. The rotation of rotating cylinder 207 slowly feeds the wooden board into the device. As the wooden board moves inside the device, it first passes the coating scraper 1. The wooden board pushes the coating scraper 1 open, allowing it to scrape paint on both sides of the board. During the process of the coating scraper 1 being pushed open, connecting block 101 moves along with the coating scraper 1. The movement of connecting block 101 causes rotating block 103 to rotate on connecting block 101 via fixing rod 102. Simultaneously, rotating block... The second 106 also rotates on the connecting block 108 via the fixing rod 107, thereby compressing the spring 104 and the telescopic rod 105. This compression of the spring 104 and the telescopic rod 105 creates a springback effect, causing the painting scraper 1 and the painting scraper 2 109 to press firmly against the wooden board. This ensures that all four sides of the board can be painted. The spring 104 and the telescopic rod 105 also keep the painting scraper 1 and the painting scraper 2 109 pressed against the board, resulting in a more even coating. After the board moves away from the painting scraper 1, the spring 104 and the telescopic rod 105's rebound will close the painting scraper 1.The wooden board then passes through the second coating scraper 109, at which point it pushes the scraper aside. During this process, the connecting block 110 moves along with the scraper. As the connecting block moves, the rotating blocks 111 and 114 rotate on the connecting blocks 110 and 115 respectively, compressing the spring 112 and the telescopic rod 113. The scraper 109 also rotates within the coating box 2 via the rotating column 116. The subsequent operation of the scraper 109 is the same as that of the first scraper. When the wooden board passes through the scraper, it needs to be held and slowly pulled out to ensure the normal operation of the device. Unused paint on the scrapers 1 and 2 will flow downwards into the collection box 217.
