[0031] Please refer to Figure 1 A slitting mechanism of composite paper, comprising a mounting frame 1, a roller 2, at least one set of slitting units 3, two sets of guide rollers 4 and a second dust suction portion 5.

[0032] The roller 2 is horizontally connected to the mounting frame 1. A plurality of annular grooves 2a are arranged on the roller surface of the roller 2.

[0033] In some embodiments, the roller surface of the roller 2 can be integral, and the plurality of annular grooves 2a are directly machined on the roller surface.

[0034] In some embodiments, the roller 2 can include a rotating shaft 2b and a plurality of roller bodies 2c. The roller bodies 2c are fixedly connected to the rotating shaft 2b and can be adjusted in the axial direction of the rotating shaft 2b at fixed positions of the rotating shaft 2b. More specifically, the roller body 2c has a stepped hole on the surface thereof, the stepped hole is connected to a through hole of the roller body 2c sleeved on the rotating shaft 2b, and the stepped hole is threadedly connected with a second bolt 2c1. When the second bolt 2c1 is loosened, the roller body 2c can move relative to the rotating shaft 2b, and when the second bolt 2c1 is tightened, the roller body 2c is fixed relative to the rotating shaft 2b. The annular groove 2a is between two adjacent roller bodies 2c.

[0035] By adjusting the fixed positions of the roller bodies 2c on the rotating shaft 2b, the annular groove 2a can be canceled by contacting the corresponding two roller bodies 2c, and the position and width of the annular groove 2a to be used can be adjusted within a certain range.

[0036] The number of slitting units 3 is set according to the number of slits of the composite paper to be slitted, and two groups of slitting units 3 are taken as examples in the drawings.

[0037] The slitting unit 3 is arranged on the mounting frame 1 and is located on the first side of the roller 2 in the horizontal direction. That is, the slitting unit 3 and the roller 2 are flush in height. More specifically, the mounting frame 1 can have a connecting strip 1a parallel to the axial direction of the roller 2 at the corresponding position, and the slitting unit 3 is mounted on the connecting strip 1a.

[0038] Referring to Figure 2 , a group of slitting units 3 includes a first mounting portion 3a, a second mounting portion 3b, a disc cutter 3c, and a first dust collection portion 3d.

[0039] The first mounting portion 3a is fixedly connected to the mounting frame 1, and more specifically, is fixedly connected to the connecting strip 1a described above. The first mounting portion 3a can also be adjusted in the axial direction of the roller 2 at the fixed position of the mounting frame 1.

[0040] In some embodiments, the first mounting portion 3a has a first sliding groove 3a1 for connecting with the mounting frame 1 to realize the sliding of the first mounting portion 3a relative to the mounting frame 1. Referring to the roller body 2c and the second bolt 2c1 described above, the first mounting portion 3a is also threadedly connected with a first threaded rod 6 capable of fixing the first mounting portion 3a to the mounting frame 1.

[0041] Referring to Figure 2 , Figure 3 and Figure 4In some embodiments, the first sliding groove 3a1 is trapezoidal in shape on the bottom surface of the first mounting portion 3a. Correspondingly, the connecting strip 1a has a matching protruding strip with a trapezoidal cross section, so that the sliding between the first mounting portion 3a and the mounting rack 1 is more stable. The end of the first threaded rod 6 is also connected to a stop block 6a, one side of which is one of the inner walls of the first sliding groove 3a1. More specifically, the bottom surface of the first mounting portion 3a has a mounting groove 3a2, and the end of the first threaded rod 6 entering the mounting groove 3a2 is stepped. The stop block 6a is located in the mounting groove 3a2 and forms the first sliding groove 3a1 in combination with the mounting groove 3a2. The stop block 6a also has a vertical first T-shaped slot for the insertion of the first threaded rod 6. The top surface of the stop block 6a is attached to the inner wall of the top of the mounting groove 3a2, and the bottom surface is attached to the connecting strip 1a.

[0042] That is, one side of the connecting strip 1a directly contacts the fixed inner wall of the first sliding groove 3a1, and the other side contacts the movable inner wall of the first sliding groove 3a1, i.e., the stop block 6a, and the stop block 6a is pressed against the connecting strip 1a by the first threaded rod 6. By adding the stop block 6a, instead of the end of the first threaded rod 6 directly pressing against the connecting strip 1a, the fixing between the first mounting portion 3a and the mounting rack 1 is more stable.

[0043] The second mounting portion 3b is fixedly connected to the first mounting portion 3a and can also be adjusted in the radial direction of the roller 2 on the first mounting portion 3a to fix the position.

[0044] The disc cutter 3c is rotationally connected to the second mounting portion 3b. That is, by adjusting the first mounting portion 3a, the disc cutter 3c can be corresponded to different annular grooves 2a, and by adjusting the second mounting portion 3b, the disc cutter 3c can be switched between entering and leaving the annular groove 2a. Of course, before adjusting the first mounting portion 3a, the disc cutter 3c needs to be in the state of leaving the annular groove 2a.

[0045] In some embodiments, the first mounting portion 3a has a second sliding groove 3a3 for connecting the second mounting portion 3b, and the second mounting portion 3b is rotationally connected to a second threaded rod 7, and the first mounting portion 3a is fixedly connected to a nut matching the second threaded rod 7. More specifically, the end of the second threaded rod 7 is stepped, and the second mounting portion 3b has a horizontal second T-shaped slot for the insertion of the end.

[0046] By rotating the second threaded rod 7, the second mounting portion 3b is driven to extend or retract relative to the first mounting portion 3a, thereby adjusting the position.

[0047] Please refer to Figure 4 In some embodiments, the bottom surface of the second mounting portion 3b has an extended stop block 3b1, which is used to limit the stop block 6a and the mounting rack 1 from loosening when the disc cutter 3c enters the annular groove 2a.

[0048] That is, the mounting groove 3a2 and the second sliding groove 3a3 are communicated, and the stopper 3b1 enters the mounting groove 3a2. After adjusting the position of the slitting unit 3 and corresponding to the corresponding annular groove 2a, rotating the first threaded rod 6, the abutting block 6a abuts against the connecting strip 1a; rotating the second threaded rod 7, the second mounting part 3b extends relative to the first mounting part 3a, and the disc cutter 3c enters the annular groove 2a until the stopper 3b1 abuts against the abutting block 6a.

[0049] Please refer to Figure 2 , the first dust collection part 3d is connected to the second mounting part 3b, and the dust collection position of the first dust collection part 3d is the edge of the disc cutter 3c. More specifically, the first dust collection part 3d can include a soft first pipe, a collection box and a fan (for convenience, only part of the first pipe is shown in the drawing); one end of the first pipe is mounted to the second connecting part, the other end is connected to the collection box, the collection box is provided with a filter element, and the fan is in the collection box for air to enter from the first pipe, pass through the filter element, and leave from the collection box.

[0050] The two groups of guide rollers 4 are rotatably connected to the mounting frame 1, and are used to make the wrapping angle of the composite paper on the roller 2 be on the half of the outer wall of the first side of the roller 2. That is, the composite paper first passes through one group of guide rollers 4, then passes through the roller 2, and then passes through the other group of guide rollers 4. Correspondingly, the number of one group of guide rollers 4 can be one or more. The positions of the two groups of guide rollers 4 relative to the roller 2 are designed to control the position of the wrapping angle of the composite paper on the roller 2, and the outer wall of the roller 2 is divided by a vertical plane, and the wrapping angle is on the half of the outer wall of the first side of the roller 2.

[0051] The second dust collection part 5 is arranged on the mounting frame 1, and the dust collection position is the composite paper below the roller 2. More specifically, the second dust collection part 5 can refer to the principle of the first dust collection part 3d, the difference is that a hard second pipe is used, provided with a plurality of air suction ports, and arranged horizontally on the mounting frame 1 at a position below the second side of the roller 2 (for convenience, only the second pipe is shown in the drawing).
