[0030] Example 1

[0031] Referring to Figure 1, this embodiment discloses a cutting device, including a cutting tool, a driving device 60, and a conveying roller 70. The output shaft of the driving device 60 is connected to a carrier for transmission. The conveying roller 70 is located below the carrier and cooperates with the carrier to form a conveying gap 71 for the material to be cut 80 to pass through. The cutting tool includes a carrier that can rotate around an axial direction. The outer surface of the carrier along the radial direction has a continuous and uninterrupted cutting edge. The projection surface of the cutting edge along the axial direction is a circular structure. The carrier is a circular roller 50, and the cutting edge is distributed at any position along the axial direction of the circular roller 50. The cutting edge includes a plurality of cutting portions 10 connected end to end. The projection surface of the cutting portion 10 along the radial direction has a concave and convex structure. When the material to be cut 80 passes through the conveying gap 71, the cutting edge cuts a slit 81 with a continuous concave and convex effect on the material to be cut. The first cut product 91 obtained by cutting is shown in Figure 2.

[0032] In this embodiment, the cutting device has the blade set on the outer side of the rotatable roller 50. The roller 50 is driven to rotate by the drive device 60. When the cutting material 80 passes through the conveying gap 71 between the conveying roller 70 and the roller 50, and the cutting part 10 has a wave-shaped structure 20, the rotating blade cuts the cutting material 80 to create a continuous wave-shaped slit 81, resulting in high cutting efficiency.

[0033] Furthermore, the dimensions and spacing of the concave-convex structure in this embodiment can be adjusted according to the cutting requirements of the product, and are not limited to a certain size and spacing.

[0034] Example 2

The circular blade 40 has a through hole 41 that runs through the center along the axis. The circular blade 40 can be directly mounted on the output shaft of the drive device 60, such as a motor, through the through hole 41. The drive device 60 drives the circular blade 40 to rotate, thereby driving the cutting part 10 to perform rotary cutting. By using the circular blade 40, it can be replaced according to the product cutting requirements, realizing quick tool replacement.

The cutting edge includes a plurality of cutting portions 10 connected end to end. The projection surface of the cutting portion 10 along the radial direction has a blade-like structure. The cutting portion 10 is a blade tip-shaped structure 30. The blade tip-shaped structure 30 includes a first bent portion 31, a second bent portion 32, a third bent portion 33, a fourth bent portion 34, a fifth bent portion 35, a sixth bent portion 36, a seventh bent portion 37, an eighth bent portion 38, a ninth bent portion 39, and a tenth bent portion 310 that are connected in sequence along the rotation direction. The fifth bent portion 35 and the sixth bent portion 36 form a V-shaped first tip protrusion, and the tenth bent portion 310 and the first bent portion 31 of another blade tip-shaped structure 30 form a V-shaped second tip protrusion. The protrusion directions of the first tip protrusion and the second tip protrusion are opposite. When the cutting material 80 is fed through the cutting section 10, the cutting section 10 of the blade tip structure 30 cuts a continuous blade tip-shaped slit 81 into the cutting material 80. The second cut product 91 obtained after two cuts is shown in Figure 10.

[0038] Furthermore, please refer to Figures 6 and 8. In this embodiment, the carrier is a circular blade 40. The circular blade 40 has a through hole 41 extending axially through the middle. The circular blade 40 can be directly mounted on the output shaft of the drive device 60, such as a motor, through the through hole 41.
