[0002] A laminating machine presses plastic film together with printed materials such as paper, providing protection against water, dirt, and chemical corrosion. Existing laminating machines mainly include a film feeding device, a conveyor belt, and a hot pressing device. The plastic film is fed to the inlet of the conveyor belt by the film feeding device, where it is bonded to the paper on the conveyor belt. Together, they are pressed together by rubber rollers and heated rollers in the hot pressing device, forming a laminated sheet. The laminated sheet is then cut.

[0003] In the prior art, such as Chinese Patent Publication No. CN220484777U, a high-efficiency die-cutting device for coated paper is disclosed. Through a limiting device and a support plate, the first electric push rod is activated according to the width of the paper to ensure that the roller is located above the front and rear sides of the paper. According to the thickness of the paper, the second electric push rod is activated to ensure that the outer wall of the roller is in contact with the upper surface of the paper, thus ensuring the stability of the paper. With the support of the support plate, the flatness of the paper is effectively improved.

[0004] However, existing technology is not convenient for smoothing the laminated paper in the die-cutting area. Therefore, when the laminated paper in the die-cutting area is wrinkled or uneven, it will affect the neatness of the cutting and the die-cutting effect.

[0005] To address the problems mentioned in the background, those skilled in the art have proposed a die-cutting apparatus for coated paper. Utility Model Content

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Please see Figures 1-4 A die-cutting apparatus for coated paper includes a processing table 1, a conveyor belt 2 installed inside the processing table 1, and a die-cutting machine 3 installed in the middle of the processing table 1 for die-cutting the coated paper. It also includes:

[0024] A leveling component, which is mounted on the processing table 1, is used to level the coated paper.

[0025] A follower fixing component is provided on the processing table 1 to fix the coated paper on the conveyor belt 2 and move synchronously with the conveyor belt 2.

[0026] A control component is disposed between the leveling component and the following fixed component, and is used to realize the movement of the leveling component.

[0027] This invention places the coated paper on the conveyor belt 2 and moves it towards the die-cutting machine 3. When the coated paper reaches the following fixing component, the following fixing component will squeeze and fix the coated paper. Then, it continues to move with the conveyor belt 2. While the following fixing component is moving, the control component will drive the flattening component to move. The flattening component will elastically squeeze the coated paper. In conjunction with the fixing component, the coated paper can be flattened, which makes it easier for the die-cutting machine 3 to accurately cut the coated paper and improve the cutting effect.

[0028] In one embodiment, the leveling component includes fixed rods 4 mounted on both sides of the top of the processing table 1, movable frames 6 slidably mounted on the fixed rods 4, leveling rollers 7 mounted on the bottom of the two movable frames 6 near their ends, a top plate 5 mounted on the top of the fixed rods 4, and elastic elements connected to the movable frames 6.

[0029] The elastic element includes fixed blocks 8 installed on the outer walls of both sides of the processing table 1. There are two fixed blocks 8 on each side, and a sliding rod 9 is provided between the two fixed blocks 8. The sliding rod 9 is slidably connected to the movable frame 6. A first spring 10 is provided between the fixed blocks 8 and the movable frame 6.

[0030] In the initial state, the control component limits the position of the movable frame 6, creating a certain gap between the flattening roller 7 and the conveyor belt 2 to facilitate the passage of the laminated paper. When the following fixing mechanism fixes the laminated paper conveyed by the conveyor belt 2 and moves with the conveyor belt 2, the control component releases the limit on the movable frame 6, allowing the movable frame 6 to move down along the slide bar 9 under the elastic force of the first spring 10. This allows the flattening roller 7 to elastically press onto the laminated paper on the conveyor belt 2. As the laminated paper fixed by the following fixing component moves, the laminated paper located below the die-cutting machine 3 can be straightened to achieve a flattened operation of the laminated paper, thereby facilitating the laminating machine to accurately cut the laminated paper.

[0031] In one embodiment, the following fixing component includes a movable frame 11, with sliders 12 installed on both sides of the movable frame 11. The processing table 1 has sliding grooves 13 on both sides that are slidably connected to the sliders 12. A hydraulic rod 15 is installed in the middle of the movable frame 11, and the hydraulic rod 15 is fixedly connected to a fixing plate 16.

[0032] When the laminated paper moves to the fixed plate 16, the hydraulic rod 15 is activated, which drives the fixed plate 16 to descend. This, in conjunction with the conveyor belt 2, fixes the laminated paper in a single position. As the conveyor belt 2 moves, the moving frame 11 also moves accordingly. The slider 12 moves along the slide groove 13 and compresses the second spring 14. After the laminated paper is cut, the hydraulic rod 15 drives the fixed plate 16 to move upward and reset. Under the elastic force of the second spring 14, the slider 12 resets, which in turn drives the moving frame 11 to reset.

[0033] In one embodiment, the control component includes trapezoidal blocks 17 installed at the bottom of both sides of the movable frame 11, and inclined blocks 18 are installed at the bottom of the movable frame 6. Both the inclined blocks 18 and the trapezoidal blocks 17 are provided with inclined surfaces.

[0034] After the following fixing component completes the fixing of the laminated paper, the following fixing component will move along the conveyor belt 2, thereby driving the trapezoidal block 17 to move synchronously. When the trapezoidal block 17 separates from the inclined block 18, the inclined block 18 is no longer constrained. Under the elastic force of the first spring 10, the movable frame 6 moves down along the slide bar 9, so that the flattening roller 7 can elastically press on the laminated paper of the conveyor belt 2, which is convenient for cooperating with the following fixing component to perform flattening operation on the laminated paper. When the movable frame 11 is reset, the inclined surface of the trapezoidal block 17 and the inclined surface of the inclined block 18 can make the trapezoidal block 17 push the inclined block 18 to rise and reset, thereby making the flattening roller 7 rise and reset.
