When the surface of the release paper 5 is evenly smoothed by the bottom of the scraper 11, the excess paint on the surface of the release paper 5 will flow along the surface of the scraper 11 to the side that has not been painted. When the scraper 11 encounters a position where the coating on the release paper 5 is less, the coating intercepted by the scraper 11 can compensate for it, thereby improving the uniformity of the coating of the release paper 5; the movable groove 12 is opened on the side surface of the scraper 11; the movable rod 13 is installed inside the movable groove 12 and is movably connected to the scraper 11. A support rod is fixed on the side of the movable rod 13 away from the conveying roller 3; the scraper 14 is sleeved on one side of the scraper 11, one end of the scraper 14 is in contact with the side wall of the scraper 11, and the other end is facing The conveying roller 3 extends; the compression spring 2 15 is sleeved on the outer surface of the movable rod 13 and is located on the side of the scraper 2 14 away from the scraper 1 11; the recovery box 16 is connected to the bottom of the scraper 11 through a support rod, and the recovery box 16 can recycle the paint collected by the scraper 2 14, and when the width of the release paper 5 changes, the movable rod 13 can be adjusted in the movable groove 12 so that the scraper 2 14 is located on both sides of the surface of the release paper 5, so that the scraper 2 14 can be scraped on the scraper 11 The excess paint cleaned is intercepted to prevent the paint from escaping along the side of the scraper 11, and after the movable rod 13 moves, the movable rod 13 is pushed toward the conveying roller 3 by the compression spring 15, and the support rod on the side of the movable rod 13 is specially in harmony with the side wall of the pad 18, and the other side of the movable rod 13 is in contact with the surface of the scraper 11 through the scraper 14, which greatly limits the movement of the movable rod 13. A hydraulic cylinder 17 is installed at the position of the scraper 11 on the surface of the bottom plate 1, and the telescopic end of the hydraulic cylinder 17 extends toward the bottom of the scraper 11.A backing plate 18 is fixed to the telescopic end of the hydraulic cylinder 17, and the backing plate 18 is arranged parallel to the scraper 11. The support rod fixed on the side of the movable rod 13 extends to the side of the backing plate 18, and the movable rod 13 is pushed toward the direction of the conveying roller 3 by the compression spring 15, so that the support rod of the movable rod 13 fits the side of the backing plate 18, and the recovery box 16 fixed at the bottom of the support rod is located below the backing plate 18. After the release paper 5 is coated by the coating box 4, the thickness of the surface coating is not uniform enough, and the release paper 5 is passed between the top of the backing plate 18 and the bottom of the scraper 11, and the distance between the backing plate 18 and the scraper 11 is controlled by the hydraulic cylinder 17, so that the distance between the release paper 5 and the bottom of the scraper 11 is The thickness of the coating of the release paper 5 is required. When the release paper 5 is conveyed, the part of the release paper 5 after coating passes through the bottom of the scraper 11, and the coating on the surface of the release paper 5 is smoothed by the scraper 11, so as to improve the uniformity of the coating thickness of the release paper 5. When the scraper 11 is smoothing, the excess coating on the surface of the release paper 5 flows to both sides along the side of the scraper 11 until it is stopped by the scraper 2 14. After a certain amount of coating is accumulated, the coating stopped by the scraper 2 14 falls into the recovery box 16 under the pad 18 for collection, thereby reducing the subsequent overflow of the coating on the surface of the release paper 5, and at the same time reducing the possibility of the coating adhering to the roller surface, reducing the difficulty of cleaning for the staff.

[0029] A first support frame 2 is fixed on the surface of the bottom plate 1, and the first support frame 2 is located on one side of the third support frame 10. A conveying roller 3 is installed inside the bottom plate 1, and a paint box 4 is arranged above the conveying roller 3. The bottom of the paint box 4 is fixed to the first support frame 2, and the paint box 4 is supported by the first support frame 2. A release paper 5 is placed between the conveying roller 3 and the paint box 4. When the release paper 5 is coated, the release paper 5 is passed between the conveying roller 3 and the release paper 5, and the surface of the release paper 5 is coated by the paint box 4, and the release paper 5 is conveyed by the conveying roller 3.

[0030] A second support frame 6 is fixed on the side of the bottom plate 1 surface away from the first support frame 2, and a group of mutually symmetrical pressure rollers 7 are fixed inside the second support frame 6. The release paper 5 is passed between the two groups of pressure rollers 7, and the release paper 5 is driven to move by the rotation of the pressure rollers 7. A waist-shaped hole 8 is provided on the surface of the second support frame 6 corresponding to the position of the transmission shaft of the upper group of pressure rollers 7, and a mounting hole is provided at the top center of the waist-shaped hole 8. A pressure rod 9 is installed in the mounting hole. An arc plate is fixed to one end of the pressure rod 9 near the transmission shaft of the pressure roller 7. A compression spring 19 is sleeved on the surface of the pressure rod 9. A limiting groove is provided inside the second support frame 6 corresponding to the position of the compression spring 19. After the release paper 5 is passed between the pressure rollers 7, the two pressure rollers 7 need to be squeezed against each other. After the release paper 5 passes between the pressure rollers 7, the upper pressure roller 7 is naturally dropped by its own weight to fit as closely as possible with the other group of pressure rollers 7. However, after the release paper 5 is coated on the surface, The friction force is small, and the upper pressure roller 7 does not have enough friction force and cannot rotate. The pressure roller 7 that cannot rotate may wrinkle the coating on the surface of the release paper 5, affecting the production quality of the release paper 5. At this time, the arc plate can be pushed by the compression spring 19 to make the arc plate push the upper group of pressure rollers 7 closer to the lower pressure roller 7, thereby increasing the clamping force between the two pressure rollers 7, and further compressing the coating on the surface of the release paper 5. After the two pressure rollers 7 clamp the release paper 5, the friction force between the upper pressure roller 7 and the release paper 5 becomes larger, thereby facilitating the synchronous rotation of the two pressure rollers 7 and avoiding wrinkles in the coating on the surface of the release paper 5.

[0031] Working principle: the release paper 5 first passes between the conveying roller 3 and the coating box 4, then passes between the scraper 11 and the pad 18, and finally passes between the two pressure rollers 7. The positions of the scraper 2 14 and the recovery box 16 are adjusted by the movable rod 13, so that the scraper 2 14 is located on both sides of the release paper 5, so that when the scraper 11 is smoothing, the scraper 2 14 intercepts the excess coating on the surface of the release paper 5 to prevent the coating from spreading. The height of the pad 18 is adjusted by the hydraulic cylinder 17, so that the distance between the release paper 5 and the bottom of the scraper 11 is the thickness of the coating required for the release paper 5. When the release paper 5 is conveyed, the coating box 4 is on the release paper 5. The surface is subjected to coating treatment so that the coating adheres to the surface of the release paper 5. When the release paper 5 passes from the bottom of the scraper 11, the excess coating on the surface of the release paper 5 is intercepted by the scraper 11, and the intercepted coating flows along the side of the scraper 11 until it is intercepted by the scraper 2 14. Guided by the scraper 2 14, the coating flows on the surface of the release paper 5 toward the side of the pad 18, and then falls from the edge of the release paper 5 into the recovery box 16 under the pad 18 to complete the collection. After the release paper 5 is smoothed by the scraper 11, it is dried for a certain period of time and passes between the two pressure rollers 7. The coating is squeezed by the pressure rollers 7 so that the coating adheres tightly to the surface of the release paper 5.
