The lifting assembly 3 is installed on the top of the top plate 103, and the bottom of the lifting assembly 3 overlaps with the top of the guide assembly 2. The flattening assembly 4 is connected to one end of the lifting assembly 3 by a shaft pin and rises and falls synchronously with the lifting assembly 3. Further, the base 101 is used to support the vertical plate 102, the vertical plate 102 is used to support the driving roller 105 and the driven roller 104, the top plate 103 is used to install the lifting assembly 3, the driving roller 105 is used to provide power, the die-cutting blade assembly 107 is used to cut the material, and the driven roller 104 is used to assist the driving roller 105 in pressurizing and conveying the material. The annular groove 108 is used to cooperate with the annular guide ring 201; this utility model designs a guide component 2, which includes two sets of annular guide rings 201 with identical structures. The annular guide rings 201 are respectively arranged on both sides of the die-cutting blade assembly 107.

[0024] Specifically, the guide assembly 2 includes two sets of annular guide rings 201 fixedly connected to the surface of the drive roller 105, and the annular guide rings 201 are located on both sides of the die-cutting blade assembly 107. The edge of the annular guide ring 201 is provided with a groove 202. Furthermore, the annular guide ring 201 is used to guide and limit the material when it enters between the drive roller 105 and the driven roller 104, so as to ensure that the material is aligned with the die-cutting blade assembly 107. The groove 202 is used to form a wave-shaped undulation on the edge of the annular guide ring 201, thereby repeatedly squeezing the lifting frame 302 during the rotation process.

[0025] The lifting assembly 3 includes guide sleeves 301 fixedly connected to both sides of the top of the top plate 103, a lifting frame 302 slidably connected inside the guide sleeves 301 and moving up and down along the guide sleeves 301, an auxiliary wheel 303 installed at the bottom of the lifting frame 302, a first return spring 304 sleeved on the surface of the lifting frame 302 and located above the auxiliary wheel 303, a first hinge frame 305 fixedly connected to one side of the lifting frame 302, a curved frame 306 fixedly connected to one side of the vertical plate 102, a second hinge frame 307 fixedly connected to the top of the curved frame 306, and a component rotatably connected to the second hinge frame 307 with one end connected to the first hinge. The connecting rod 308 is connected to the frame 305. Further, the guide sleeve 301 is used to slide and connect the lifting frame 302 and guide the movement trajectory of the lifting frame 302. The lifting frame 302 is used to drive the connecting rod 308 to swing repeatedly. The auxiliary wheel 303 is used to connect the edge of the annular guide ring 201. The first return spring 304 is used to reset the lifting frame 302. The first hinge frame 305 is used to connect the short end of the connecting rod 308. The curved frame 306 is used to support the second hinge frame 307. The second hinge frame 307 is used to rotatably connect the connecting rod 308. The connecting rod 308 is used to drive the flattening component 4 to move up and down during the swinging process.

[0026] The leveling assembly 4 includes a hinge seat 401 rotatably mounted on the end of the connecting rod 308 away from the second hinge frame 307, a movable rod 402 rotatably connected to the bottom of the hinge seat 401, a leveling wheel 403 rotatably connected to the bottom of the movable rod 402, and a second return spring 404 fixedly connected between the movable rods 402. Further, the hinge seat 401 is used to connect the long end of the connecting rod 308, and the hinge shaft is also used to rotatably connect the movable rod 402. The movable rod 402 is used to support the leveling wheel 403, the leveling wheel 403 is used to stretch the material, and the second return spring 404 is used to assist the movable rod 402 in returning to its original position.

[0027] It is worth mentioning that the die-cutting blade assembly 107 is arranged in a ring, and the cutting edge of the die-cutting blade assembly 107 is wavy, so that the cutting edge on the material surface is also wavy. The groove 202 is semi-circular, and the grooves 202 are connected to form a ring-shaped wavy shape. In this way, the lifting frame 302 can be repeatedly squeezed during the rotation of the ring guide ring 201. The distance between the two ring guide rings 201 is V-shaped from the inside to the outside, so that the material can be gradually guided and limited when it enters.

[0028] It is worth noting that the connecting rod 308 is divided into a long end and a short end at the connection point with the second hinge frame 307. The short end is connected to the first hinge frame 305, and the long end is connected to the hinge seat 401. In this way, when the connecting rod 308 swings, the short end swings a short distance, which can drive the long end to swing a long distance. The surface of the flattening wheel 403 is bonded with a rubber pad, and the surface of the rubber pad is provided with irregular ridges, which can increase the friction between the pad and the material when the material is stretched.

[0029] Working Principle: This embodiment provides a wavy line die structure for a coating die-cutting machine. In use, the motor 106 rotates, driving the active roller 105 and the driven roller 104 to rotate. During the rotation of the active roller 105, the die-cutting blade assembly 107 rotates. When the material passes between the active roller 105 and the driven roller 104, the die-cutting blade assembly 107 cuts the material. Because annular guide rings 201 are provided on both sides of the die-cutting blade assembly 107, and the spacing between the two annular guide rings 201 is arranged in a figure-eight shape from the inside out, the annular guide rings 201 can guide and limit the material when it enters the active roller 105 and the driven roller 104, preventing material slippage and ensuring neat material cutting during die-cutting. This improves product quality and reduces defect rates. Furthermore, because semi-circular grooves 202 are evenly distributed along the edge of the annular guide ring 201, the lifting frame 302 can be repeatedly compressed during the rotation of the annular guide ring 201. Under the action of the auxiliary wheel 303, the lifting frame 302 moves up and down synchronously with the rotation of the annular guide ring 201. The up-and-down movement of the lifting frame 302 drives the connecting rod 308 to move repeatedly along the second hinge frame 307. During this repeated movement, the connecting rod 308 drives the flattening component 4 to move up and down. During this up-and-down movement, the flattening wheel 403 stretches both ends of the material, preventing wrinkles on the material surface and further improving product quality.

[0030] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
