[0029] 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.

[0030] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a melamine paper recoating machine, comprising a machine body 1, a solution tank 2 located at the top left of the machine body 1, and a conveying roller 3 disposed inside the solution tank 2. The machine body 1 is the main body of the melamine paper recoating machine, used to coat melamine paper. A feeding mechanism is provided on the left side of the machine body 1, including a feeding component 4. The feeding component 4 includes a buoyancy block 41 slidably connected to the inner wall of the solution tank 2 near the left side. The buoyancy block 41 floats above the coating material, used to control the outward flow of the coating material at the opening. The top of the buoyancy block 41 is tilted to the right, which allows the coating material to flow to the right into the solution tank 2, preventing it from remaining on the buoyancy block 41. A storage tank 42 for storing coating material is fixedly connected to the top left of the machine body 1. The top of the storage tank 42 is fixedly... The container is connected to a feed pipe for adding paint. Inside the storage tank 42, there is a storage tank 43 for storing paint. At the bottom right side of the storage tank 43, there is an opening for adding paint into the solution tank 2. Paint is added to the solution tank 2 from the opening to the right. A buoyancy block 41 is positioned to the right of the opening to block it. The buoyancy block 41 initially blocks the opening. When the paint in the solution tank 2 is used up, the paint level drops, causing the buoyancy block 41 to drop. At this time, the opening is opened, and the paint in the storage tank 43 flows to the right through the opening and is added to the solution tank 2 along the sloping top of the buoyancy block 41. After the liquid level in the solution tank 2 rises to the initial height, the buoyancy block 41 returns to its original position to block the opening again, thus automatically adding paint.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The feeding mechanism also includes an adjustment component 5, which is used to adjust the size of the opening on the right side of the storage tank 43 and the storage box 42. The adjustment component 5 includes a fixed block 53 fixedly connected to the right side of the storage box 42 near the top. The fixed block 53 supports a threaded rod 52. The fixed block 53 has a threaded rod 52 that drives the guide block 51 to move up and down through the middle of the fixed block 53. The bottom end of the threaded rod 52 is rotatably connected to the guide block 51 that drives the adjustment plate 54 to move up and down. The left side of the guide block 51 is fixedly connected to the adjustment plate 54. The lifting and lowering of the adjustment plate 54 can adjust the size of the opening, thereby adapting the position of the buoyancy block 41. The bottom end of the adjustment plate 54 is fixedly connected to a sealing strip to increase the sealing performance, and the sealing strip is snapped into the bottom end of the opening. The adjustment plate 54 is slidably connected to the inner wall of the right side of the storage box 42 and the opening on the right side of the storage tank 43, and is used to control the size of the opening. The guide block 51 is vertically slidably connected to the right side of the storage box 42. The top end of the threaded rod 52 is fixedly connected to a turntable 55.

[0032] Reference Figure 1 , Figure 2 and Figure 4The inner wall of the solution tank 2 is equipped with a cleaning component 6. The cleaning component 6 includes a pushing block 61 that moves a scraper 62. The pushing block 61 is L-shaped, and its bottom end, which extends downward on the left side, is fixedly connected to a scraper 62 that can scrape off residual or adhered paint from the bottom inner wall of the solution tank 2, thereby improving the effect of subsequent coating. The scraper 62 is slidably connected to the bottom inner wall of the solution tank 2. The top of the pushing block 61 extends to the right and is slidably connected to the top of the machine body 1. Both the front and rear outer walls of the machine body 1 have slots 68. Opening the slots 68 allows the paint to be scraped out for cleaning, improving the convenience of cleaning. The bottom ends of both sets of slots 68 are inclined, which allows the paint to be better cleaned along the inclined surface. The inner walls of both sets of slots 68 are fitted with locking blocks 63 to protect the slots 68. A handle is fixedly connected to the outside of the locking blocks 63. Sealing strips are fixedly connected around the outer walls of the locking blocks 63 to increase the sealing. The front and rear outer walls of the machine body 1 are close to the slots 68. Each set of fixed plates 64 is fixedly connected to the top to provide support. The top of each of the two sets of fixed plates 64 is slidably connected to two sets of limiting blocks 67 that limit the position of the locking block 63. The multiple sets of limiting blocks 67 are attached to the outer surface of the body 1. The top of the front and rear sets of limiting blocks 67 are respectively fixedly connected to moving plates 66 that drive the limiting blocks 67 to move. The bottom outer side of the limiting blocks 67 is set with a slope. The slope setting allows the locking block 63 to be pushed directly to squeeze the slope, so that the locking block 63 can be installed quickly without having to pull the limiting blocks 67 upward before installation, which improves the convenience of installation. The two sets of moving plates 66 are elastically connected to the two sets of fixed plates 64 by springs 65. The multiple sets of limiting blocks 67 are respectively locked on the outer side of the two sets of locking blocks 63. By moving the moving plates 66 upward, the limiting blocks 67 are moved upward to release the limitation of the locking block 63. At this time, the locking slot 68 can be opened for cleaning. At the same time, the elastic force of the spring 65 can make the limiting blocks 67 quickly reset.

[0033] Working principle: When the melamine paper recoating machine is in operation, the solution tank 2 initially contains a certain amount of paint. The buoyancy block 41 floats on the paint with its top tilted to the right. Its initial position blocks the opening at the bottom right side of the storage tank 43. The storage box 42 replenishes the paint through the feed pipe and stores it in the storage tank 43. As the operation progresses, the paint in the solution tank 2 is continuously consumed, and the liquid level drops. The buoyancy block 41 drops accordingly, and the opening above is opened. The paint in the storage tank 43 flows out through the opening and flows into the solution tank 2 along the inclined surface at the top of the buoyancy block 41. When the liquid level in the solution tank 2 rises back to the initial height, the buoyancy block 41 resets and blocks the opening again, thereby realizing automatic paint replenishment, maintaining a stable paint level in the solution tank 2, and ensuring that the coating operation continues stably.

[0034] By rotating the turntable 55, the threaded rod 52, which is fixedly connected to the turntable 55, rotates accordingly. Since the threaded rod 52 is threadedly connected to the fixed block 53, and the guide block 51 is vertically slidably connected to the right side of the storage box 42, when the threaded rod 52 rotates, the guide block 51 will move up and down along the right side of the storage box 42, thereby driving the adjusting plate 54 fixed thereto to rise and fall. The adjusting plate 54 slides on the right inner wall of the storage box 42 and at the right opening of the storage trough 43. By changing its position, the size of the opening can be adjusted, thereby adapting to the initial position of the buoyancy block 41, improving flexibility and adaptability. At the same time, the sealing strip at the bottom of the adjusting plate 54 ensures the sealing of the opening.

[0035] If it is necessary to clean the residual paint at the bottom of the solution tank 2 during or after the recoating operation, the moving plate 66 can be moved upward, which will drive the limiting block 67 to move upward, overcome the elastic force of the spring 65, and release the limiting of the locking block 63. At this time, the locking block 63 will no longer be stuck in the locking opening 68. Pull it outward to open it, push the L-shaped pushing block 61, and make the scraper 62 slide on the inner wall of the bottom of the solution tank 2, scraping the residual or attached paint towards the locking opening 68. Since the bottom end of the locking opening 68 is inclined, the paint can flow out more smoothly along the slope. After cleaning, release the moving plate 66. Under the elastic force of the spring 65, the limiting block 67 will quickly reset, re-lock the locking block 63, and close the locking opening 68, preparing for the next coating operation, ensuring the solution tank 2 is clean, and improving the subsequent coating effect.
