[0029] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0030] like Figures 1 to 3 As shown, this embodiment provides a slitting knife device for cooperating with the bottom knife 4 to slit the parts to be slit.

[0031] The slitting blade assembly comprises a blade holder 1, a blade head assembly 2, and a position adjustment mechanism 3. The blade head assembly 2 is mounted on the blade holder 1 and includes a circular blade 21. The circular blade 21 is arranged in a staggered arrangement relative to the bed blade 4, enabling the circular blade 21 to cut the material in an alternating manner with the bed blade 4 to achieve slitting. Optionally, the material to be slit is thick aluminum foil. Of course, the material to be slit may also be other coiled materials, and this embodiment is not particularly limited thereto.

[0032] Among them, the position adjustment mechanism 3 includes a horizontal adjustment module 31 and a deflection adjustment module 32. The driving end of the horizontal adjustment module 31 is connected to the deflection adjustment module 32, which is used to adjust the horizontal position of the deflection adjustment module 32. The driving end of the deflection adjustment module 32 is connected to the tool holder 1, which is used to adjust the cutting angle of the circular knife 21. Therefore, through the setting of the horizontal adjustment module 31, the lateral position of the circular knife 21 relative to the bottom knife 4 and the cutting depth of the circular knife 21 can be adjusted to meet the actual working conditions. Through the setting of the deflection adjustment module 32, the deflection angle and the cutting angle of the circular knife 21 can be adjusted to reduce the difficulty of cutting the parts to be cut. It is easy to adjust and can avoid the phenomenon of warping, polygonal or ruffled edges of the parts to be cut after cutting, thereby improving the production quality of the product and reducing the production cost.

[0033] Furthermore, the deflection adjustment module 32 includes a rotation adjustment assembly 321, the driving end of which is connected to the tool holder 1 and is used to drive the tool holder 1 to rotate. The cutting surface of the circular blade 21 is parallel to the rotation axis of the rotation adjustment assembly 321, so that during the rotation of the tool holder 1, the circular blade 21 can rotate accordingly, thereby adjusting the cutting angle of the cutting surface of the circular blade 21 relative to the cutting surface of the bottom blade 4. At the same time, the deflection adjustment module 32 also includes an axial angle adjustment assembly 322, which is arranged at the driving end of the horizontal adjustment module 31. The driving end of the axial angle adjustment assembly 322 is connected to the rotation adjustment assembly 321 and is used to drive the rotation adjustment assembly 321 to deflect along the axial direction of the bottom blade 4. Therefore, during the axial deflection of the rotation adjustment assembly 321 along the axial direction of the bottom blade 4, the circular blade 21 can deflect accordingly, thereby adjusting the deflection angle of the cutting surface of the circular blade 21 relative to the cutting surface of the bottom blade 4. Optionally, the rotation adjustment component 321 is a rotation platform, and the axial angular position adjustment component 322 is an angular position table.

[0034] Furthermore, the horizontal adjustment module 31 includes an axial movement component 311 and a horizontal fine-tuning component 312. The driving end of the axial movement component 311 is connected to the horizontal fine-tuning component 312, which is used to drive the horizontal fine-tuning component 312 to move axially along the bottom knife 4. The driving end of the horizontal fine-tuning component 312 is connected to the deflection adjustment module 32, which is used to drive the deflection adjustment module 32 to move horizontally. Therefore, through the setting of the axial movement component 311, the lateral position of the circular knife 21 can be adjusted so that the circular knife 21 can cooperate with the bottom knife 4 at different positions of the knife shaft 6. At the same time, through the setting of the horizontal fine-tuning component 312, the lateral position and cutting depth of the circular knife 21 can be adjusted with high precision to meet the positional accuracy requirements between the circular knife 21 and the bottom knife 4. Optionally, the axial movement component 311 is a linear displacement platform, and the horizontal fine-tuning component 312 is a fine-tuning platform.

[0035] like Figure 2 and Figure 3As shown, the cutter head assembly 2 also includes a mounting shaft 22 and a cutter disc assembly 23. The mounting shaft 22 is detachably mounted on the cutter holder 1, the cutter disc assembly 23 is mounted on the mounting shaft 22, and the circular knife 21 is mounted on the cutter disc assembly 23. Thus, the detachable connection between the mounting shaft 22 and the cutter holder 1 facilitates the maintenance or replacement of the cutter head assembly 2, thereby extending the service life of the slitting knife device. Specifically, the cutter disc assembly 23 includes a side seat 231 and a cover plate 232. The side seat 231 is mounted on the mounting shaft 22, and the circular knife 21 is sandwiched between the side seat 231 and the cover plate 232. The side seat 231 and the cover plate 232 are detachably connected. Therefore, after the cover plate 232 is removed from the side seat 231, the easily worn circular knife 21 can be replaced separately, thereby reducing maintenance costs. Optionally, the cover plate 232 is located on the side of the side seat 231 away from the mounting shaft 22 , so that the staff can replace the circular knife 21 only by disassembling the cover plate 232 without having to disassemble the cutter head assembly 2 as a whole.

[0036] Furthermore, the tool holder 1 is provided with a waist hole 11, and a mounting shaft 22 is vertically movable in the waist hole 11. Thus, by adjusting the position of the mounting shaft 22 in the waist hole 11, the vertical height of the circular blade 21 can be adjusted. Optionally, the waist hole 11 is an arc-shaped hole, so that while adjusting the vertical height of the circular blade 21, the horizontal spacing of the circular blade 21 relative to the bed blade 4 can also be slightly adjusted to meet actual working conditions.

[0037] This embodiment also provides a slitting machine, including the slitting knife device as described above, such as Figure 1 As shown, the slitting machine also includes a frame 5, a knife shaft 6 and a bottom knife 4. The bottom knife 4 is arranged on the knife shaft 6. The knife shaft 6 and the horizontal adjustment module 31 are both arranged on the frame 5. Therefore, the slitting machine uses the slitting knife device as mentioned above. While satisfying the lateral position of the circular knife 21 relative to the bottom knife 4 and the cutting depth of the circular knife 21 can be adjusted, it can also meet the adjustment of the deflection angle and the cutting angle of the circular knife 21 to reduce the difficulty of cutting the parts to be cut. It is easy to adjust and can avoid the phenomenon of warping, polygonal or ruffled edges of the parts to be cut after cutting, thereby improving the production quality of the product and reducing the production cost.

[0038] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
