[0002] In production, die-cutting is a commonly used process, mainly used to cut paper, plastic film and other materials of various shapes and sizes. As a special self-adhesive material, special-shaped self-adhesive stickers often need to be cut using die-cutting technology because of their unique shapes and complex patterns. However, the existing die-cutting devices are often inefficient and low-precision when processing special-shaped self-adhesive stickers, and may even damage the materials.

[0027] The driving assembly 22 is arranged on the inner side of the mounting frame 1 and is used to drive the driving half wheel 214 to rotate;

[0028] The die-cutting assembly 23 is disposed on one side of the toothed disc 217 and is used for die-cutting special-shaped adhesive labels.

[0029] In this embodiment, the driving component 22 includes a driving motor 221 fixedly mounted on the inner wall of one side of the mounting frame 1, and a transmission rod 222 is fixed on one side of the driving half wheel 214, and the power output end of the driving motor 221 is connected to the power input end of the transmission rod 222; by starting the driving motor 221, the driving motor 221 drives the driving half wheel 214 to rotate through the transmission rod 222.

[0030] In this embodiment, the die-cutting assembly 23 includes several groups of columns 231 welded to the side walls of the toothed disk 217, and the groups of columns 231 have integrally formed limit rings 232 on the outside. One side of the column 231 is rotatably connected to a cylinder 233, and the inner wall of the cylinder 233 is provided with an annular groove for the limit ring 232 to cooperate with the rotation. The other side of the cylinder 233 is fixedly connected to a sleeve 234, and the inner wall of the sleeve 234 is slidably connected to a sliding column 235. A gasket 236 is fixed to the outer wall of the lower part of the sliding column 235, and a tension spring 237 is installed between the gasket 236 and the sleeve 234. A die-cutting knife block 238 is installed at the bottom end of the sliding column 235; the design of the tension spring 237 ensures that the sliding column 235 slides down stably while allowing the die-cutting knife block 238 to fall naturally.
