[0018] Please see Figures 1 to 5 The compatible tool structure of the embodiment of the utility model, including the tool holder 1, the tool holder 2, the tool shaft 3, the first blade 4 and the second blade 5, the guide groove 11 is formed in the tool holder 1, the tool shaft 3 is installed in the tool holder 1 through the guide groove 11, the tool holder 2 is detachably arranged in the tool holder 1, the first blade 4 is arranged in the tool holder 2, and the second blade 5 is arranged along the outer edge of the tool holder 1.

[0019] In the above embodiment, the cutter shaft 3 is installed in the cutter holder 1 through the guide groove 11, which limits the cutter shaft 3 and ensures the stability and cutting accuracy of the cutter. The cutter holder 2 is detachably arranged on the cutter holder 1, which not only simplifies the replacement process of the cutter, but also improves the safety of the operation. The first blade 4 is installed on the cutter holder 2, which is detachably arranged on the cutter holder 1, and the second blade 5 is arranged along the outer edge of the cutter holder 1.

[0020] When the second blade 5 is used, the cutter shaft 3 is fixed with the cutter holder 1 through the guide groove 11 and rotates for cutting. When the first blade 4 is used, the cutter shaft 3 is currently in a static state by being externally pressed by a cylinder, which ensures the stability of the slitting effect, rather than continuing to rotate with the cutter shaft.

[0021] In terms of safety, since the cutter holder 2 can be quickly detached, the complexity and potential risks of replacing the entire cutter of different models during traditional cutter replacement are avoided, thereby improving the safety of the operation.

[0022] In terms of cost reduction, the first blade 4 is a straight blade and the second blade 5 is a round blade. Different types of blades can be used according to different needs, and different specifications of cutter holders 1 do not need to be used due to different blade models. The parts are universal, which reduces the production cost.

[0023] In terms of flexibility, the cutter structure shows high adaptability. For example, when a round blade is needed for film cutting, the user can directly use the blade on the cutter holder 1 for cutting; when a straight blade is needed, the user can install the cutter holder 2 on the cutter holder 1 and use it with the blade. This design allows users to quickly adjust the cutter structure according to different cutting needs, thereby improving the flexibility and efficiency of the equipment.

[0024] The cutter structure is applied to paper slitting machines, plastic film slitting machines, etc. Taking a paper slitting machine as an example, the user can select the first blade 4 installed on the cutter holder 2 or directly use the second blade 5 on the cutter holder 1 according to the thickness and width of the paper. During cutting, the blade rotates at high speed under the drive of the cutter shaft 3, cutting the paper into the desired size and shape, and reducing the operation difficulty and cost.

[0025] Please refer to Figures 1 to 4 In another embodiment, the shape of the cutter holder 1 is circular.

[0026] In the above embodiment, the shape of the cutter holder 1 is circular, which makes the compatible cutter structure more efficient and stable in the slitting machine. During operation, the cutter shaft 3 is installed through the guide groove 11 inside the cutter holder 1, and the second blade 5 is arranged along the outer edge of the circular cutter holder 1 and rotates with the cutter shaft 3 for cutting.

[0028] In the above embodiment, the holder 2 is locked to the seat 1 by screw thread, which facilitates the installation and removal of the holder 2 on the seat 1, and the first blade 4 on the holder 2 can also be installed and removed in the same way.

[0029] Please refer to Figure 1 In another embodiment, the seat 1 is provided with two screw holes 7, and the two screw holes 7 are arranged along the outer edge of the blade shaft 3.

[0030] In the above embodiment, the two screw holes 7 are arranged on the seat 1 in an up-down arrangement and along the outer edge of the blade shaft 3, and the upper end and the lower end of the holder 2 are fixed, which plays a limiting role, effectively preventing the holder 2 from shaking during cutting, and ensuring the accuracy and safety of cutting.

[0031] In the above embodiment, in the tool structure, the holder 2 is locked to the seat 1 by screw thread, which ensures the stability of the installation of the holder 2; and the blade is locked to the holder 2 by screw thread, which ensures the stability of the blade during cutting. During work, the blade shaft 3 drives the blade of the support to rotate, and when the holder 2 and the first blade 4 and the second blade 5 are assembled, the seat 1 should be stationary during the operation of the equipment, so as to ensure the stability of the cutting.

[0032] Please refer to Figure 1 and Figure 2 In another embodiment, a spring 6 is arranged between the seat 1 and the second blade 5.

[0033] In the above embodiment, a spring 6 is arranged between the seat 1 and the second blade 5. During work, the blade shaft 3 drives the second blade 5 to rotate, and the second blade 5 can maintain stable and moderate pressure under the action of the spring 6, which ensures the uniformity and efficiency of cutting.

[0034] Specifically, the spring 6 plays three roles: first, it provides stable support for the second blade 5, making it less likely to shake during rotation; second, through the elastic force of the spring 6, the second blade 5 can tightly fit the cut material, improving the cutting effect; third, the buffering effect of the spring 6 can reduce the impact and vibration during cutting to some extent, protecting the tool and the cutting machine.

[0035] Please refer to Figure 1 and Figure 3 In another embodiment, the second blade 5 is locked to the side of the seat 1 by screw thread.

[0036] In the above embodiment, the cutter shaft 3 drives the cutter holder 1 to rotate, and the second cutter blade 5 performs cutting operation accordingly. The threaded locking not only ensures the stability of the second cutter blade 5 under high-speed rotation, but also facilitates quick replacement of the second cutter blade, thereby improving cutting efficiency and operation convenience.

[0037] Preferably, the cutter holder 2 is located at one side of the cutter holder 1, and the second cutter blade 5 is located at the other side of the cutter holder 1.

[0038] In the above embodiment, the cutter holder 2 is located at one side of the cutter holder 1, and the second cutter blade 5 is located at the other side of the cutter holder 1. Such a layout enables the hands of the operator to be away from the second cutter blade 5 when the cutter holder 2 is installed or dismounted, thereby effectively avoiding cutting injury.
