Obviously, the described embodiments are only some of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by persons skilled in the art without inventive effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed to indicate or imply relative importance or to implicitly specify the number of the technical features indicated. Therefore, features designated "first" or "second" may explicitly or implicitly include one or more of the designated features.

[0024] In some embodiments of the present application, a cutting device 100 is provided, referring to Figures 1 to 4 as well as Figures 6 to 8 The cutting device 100 includes a first cutter 10 and a second cutter 20, referring to Figure 1 and Figure 2 The first cutter 10 and the second cutter 20 are spaced apart along the first direction X. The cutting device 100 has a first direction X, a second direction Y and a third direction Z that intersect each other. Figures 1 to 8 In the illustrated embodiment, the first direction X, the second direction Y, and the third direction Z are orthogonal to each other.

[0025] Reference Figures 2 to 4 as well as Figure 7 The first cutter 10 includes a first surface 101 and a second surface 102 that are opposite to each other along the second direction Y. The first surface 101 is provided with at least one first cutting edge 11, and the second surface 102 is provided with at least one second cutting edge 12. Figures 1 and 2 as well as Figure 8 The second cutter 20 extends along the first direction X, and a blade 21 is provided at one end of the second cutter 20 adjacent to the first cutter 10 along the first direction X.

[0026] Among them, one of the first cutter 10 and the second cutter 20 can be close to the other along the first direction X, specifically as follows Figure 1 and Figure 2 In the embodiment shown, the second cutter 20 can move along the first direction X toward the first cutter 10, and the first cutting edge 11 on the first cutter 10 cooperates with the blade 21 on the second cutter 20 to cut the piece 200 to be cut. Moreover, the first cutter 10 can be flipped so that the second cutting edge 12 on the first cutter 10 cooperates with the blade to cut the piece 200 to be cut.

[0027] In the existing cutting mechanisms, most of them cut the material to be cut by the relative movement between the upper cutter and the lower cutter. The lower cutter is generally a fixed cutter and the upper cutter is a movable cutter. The upper cutter approaches the lower cutter to cooperate with the lower cutter to cut the workpiece to be cut. As the number of cutting increases, the cutting edge (or blade) of the cutter will cause wear, especially the lower cutter. In addition to the wear caused by contact with the workpiece to be cut, the lower cutter will also be impacted by the upper cutter, resulting in a higher degree of wear of the lower cutter than that of the upper cutter. In order to ensure the cutting quality and cutting efficiency, the cutter with higher wear needs to be replaced. The number of replacements of the lower cutter is more frequent than that of the upper cutter, resulting in a large number of spare parts for the lower cutter, which increases the cutting cost.

[0028] The cutting device 100 provided in the embodiment of the present application is provided with a first cutter 10 and a second cutter 20 spaced apart along a first direction X. The first cutter 10 includes a first surface 101 and a second surface 102 arranged opposite to each other along a second direction Y. The first surface 101 is provided with at least one first cutting edge 11, and the second surface 102 is provided with at least one second cutting edge 12. A cutting edge 21 is provided on the second cutter 20 adjacent to one end of the first cutter 10 along the first direction X. The second cutter 20 is close to the first cutter 10 along the first direction X. The cutting edge 21 on the second cutter 20 cooperates with the first cutting edge 11 on the first cutter 10 to form a cutting of the workpiece 200 to be cut. Since the first cutter 10 is fixed during the cutting process, the first cutting edge 11 on the first cutter 10 is fixed during the cutting process. During the cutting process, the second cutting knife 10 will rub against the workpiece 200 to be cut, causing wear, and will also be impacted by the blade 21 on the second cutting knife 20 along the first direction X. As the number of times the blade 21 cooperates with the first cutting edge 11 for cutting increases, the wear of the first cutting edge 11 is more serious, then the first cutting knife 10 can be flipped over. Specifically, the first cutting knife 10 is flipped 180° so that the second cutting edge 12 on the second surface 102 of the first cutting knife 10 cooperates with the blade 21 on the second cutting knife 20 to cut the workpiece 200. This improves the utilization rate of the first cutting knife 10 while ensuring the cutting quality and cutting efficiency, avoids the situation where the first cutting knife 10 needs to be replaced because the first cutting edge 11 is worn, reduces the number of replacements of the first cutting knife 10, and reduces the use cost of the cutting device 100.

[0029] Among them, reference Figure 1 and Figure 2 The workpiece 200 to be cut includes a material strip 210 and a plurality of materials 220. The material strip 210 extends along the second direction Y. The plurality of materials 220 are arranged at intervals along the second direction Y and are respectively connected to the material strip 210. The first cutting edge 11 or the second cutting edge 12 on the first cutter 10 cooperates with the blade 21 on the second cutter 20 to form a cutting of the material strip 210 between two adjacent materials 220 along the second direction Y.

[0030] In some embodiments, reference Figure 3 and Figure 4 There are multiple first cutting edges 11, which are spaced apart along the circumferential direction of the first surface 101 and arranged at the edge of the first surface 101. The first cutter 10 can rotate so that any one of the first cutting edges 11 cooperates with the blade 21 on the second cutter 20 to cut the workpiece 200. Figures 3 and 4In the illustrated embodiment, the first cutter 10 is square in shape, the cross-sectional shape of the first surface 101 is a quadrilateral, the first surface 101 has four sides, and the number of first cutting edges 11 is four. The four first cutting edges 11 are arranged at intervals along the circumferential direction of the first surface 101, and a first cutting edge 11 is provided on each edge of the first surface 101. When the first cutter 10 cooperates with the second cutter 20 for cutting, only one first cutting edge 11 cooperates with the blade 21 at a time. Therefore, when the first cutting edge 11 is worn, the first cutter 10 can rotate 90°, 180° or 270°, so that one of the remaining three first cutting edges 11 cooperates with the blade 21 to cut the workpiece 200 to be cut, thereby ensuring cutting efficiency and cutting quality.

[0031] In some embodiments, reference Figure 3 and Figure 4 The number of the second cutting edges 12 is multiple, and the multiple second cutting edges 12 are spaced apart along the circumferential direction of the second surface 102 at the edge of the second surface 102. The first cutter 10 can rotate so that any second cutting edge 12 cooperates with the blade 21 on the second cutter 20 to cut the workpiece 200. Figures 3 and 4 In the illustrated embodiment, the second cutting edge 12 is square in shape, the cross-sectional shape of the second surface 102 is a quadrilateral, and the second surface 102 has four sides. Accordingly, the number of the second cutting edges 12 is four, and the four second cutting edges 12 are spaced apart along the circumferential direction of the second surface 102. A second cutting edge 12 is provided on each edge of the second surface 102. When the first cutter 10 cooperates with the second cutter 20 for cutting, only one second cutting edge 12 cooperates with the blade 21 at a time. Therefore, when the second cutting edge 12 is worn, the first cutter 10 can rotate 90°, 180° or 270°, so that one of the remaining three second cutting edges 12 cooperates with the blade 21 to cut the workpiece 200 to be cut, thereby ensuring cutting efficiency and cutting quality.

[0032] Moreover, combined with the design that the first cutter 10 can be flipped, the first cutter 10 can provide a total of eight cutting edges (i.e., four first cutting edges 11 and four second cutting edges 12) to cooperate with the second cutter 20 for cutting, thereby effectively improving the service life of the first cutter 10, reducing the number of times the first cutter 10 is replaced, and reducing the cost of using the cutting device 100.

[0033] In other implementations, the cross-sectional shape of the first surface 101 and the second surface 102 can be a polygon such as a triangle, a pentagon, or a hexagon, so different numbers of first cutting edges 11 and second cutting edges 12 can be selected, and the specific selection can be made according to actual usage requirements.

[0034] In some embodiments, reference Figures 1 and 2 as well as Figures 5 to 7 The cutting device 100 further includes a first knife seat 30, referring to Figures 1 and 2 The first knife seat 30 and the second cutter 20 are arranged at intervals along the first direction X, the first knife seat 30 extends along the second direction Y, the first cutter 10 and the first knife seat 30 are detachably connected along the second direction Y, the first cutting edge 11 and the blade 21 cooperate to form a cutting of the workpiece 200 to be cut, and the first cutter 10 can be separated from the first knife seat 30 and connected to the first knife seat 30 after being flipped, so that the second cutting edge 12 and the blade 21 cooperate to form a cutting of the workpiece 200 to be cut.

[0035] In some implementations, reference Figures 1 and 2 as well as Figures 5 to 7 The first knife seat 30 includes a first end 301 and a second end 302 arranged opposite to each other along the second direction Y. The second cutter 20 is adjacent to the first end 301 along the second direction Y. The second cutter 20 and the first end 301 are spaced apart along the third direction Z. The first cutter 10 is detachably connected to the first end 301 along the second direction Y. The first cutting edge 11 cooperates with the blade 21 to form a cutting of the workpiece 200 to be cut. That is, when the first cutter 10 is installed at the first end 301, the second surface 102 abuts against the first end 301, and the first surface 101 is away from the first end 301. The first cutter 10 and the second cutter 20 are connected through the first cutting edge 11 on the first surface 101. The blade 21 on the first cutting edge 12 cooperates for cutting. When the first cutting edge 11 is severely worn, the first cutter 10 can be removed from the first cutter seat 30 to separate the first cutter 10 from the first cutter seat 30. Then, after the first cutter 10 is turned 180°, the first cutter 10 is connected to the first end 301 of the first cutter seat 30, so that the first surface 101 abuts the first end 301 and the second surface 102 is away from the first end 301, so that the second cutting edge 12 cooperates with the blade 21 to form a cutting of the workpiece 200 to be cut, so as to ensure the cutting quality and cutting efficiency, reduce the number of replacements of the first cutter 10, and reduce the use cost of the cutting device 100.

[0036] In some embodiments, when a first cutting edge 11 is worn due to cutting in cooperation with the blade 21, the first cutter 10 can be removed from the first knife seat 30, so that the first cutter 10 is separated from the first knife seat 30, and then the first cutter 10 is rotated 90°, 180° or 270°, and then the first cutter 10 is connected to the first end 301 of the first knife seat 30, so that the second surface 102 remains in contact with the first end 301, and the first surface 101 is away from the first end 301, so that one of the remaining three unworn first cutting edges 11 on the first surface 101 cooperates with the blade 21 to cut the workpiece 200 to be cut, thereby ensuring cutting efficiency and cutting quality.

[0037] In some embodiments, when the second cutting edge 12 and the blade 21 cooperate in cutting and become worn, the first cutter 10 can be removed from the first cutter seat 30, so that the first cutter 10 is separated from the first cutter seat 30, and then the first cutter 10 is rotated 90°, 180° or 270°, and then the first cutter 10 is connected to the first end 301 of the first cutter seat 30, so that the first surface 101 abuts against the first end 301, and the second surface 102 is away from the first end 301, so that one of the remaining three unworn second cutting edges 12 on the second surface 102 cooperates with the blade 21 to cut the workpiece 200 to be cut, thereby ensuring cutting efficiency and cutting quality.

[0038] In some embodiments, reference Figures 3 and 4 as well as Figure 7 , along the second direction Y, a first groove 1011 is provided on the first surface 101 of the first cutter 10, and a second groove 1021 is provided on the second surface 102. The first cutter 10 is detachably connected to the first knife seat 30 along the second direction Y through the second groove 1021, and the first cutting edge 11 cooperates with the blade 21 to form a cutting of the workpiece 200 to be cut. The first cutter 10 is separated from the first knife seat 30, and after the first cutter 10 is flipped, it is detachably connected to the first knife seat 30 along the second direction Y through the first groove 1011, so that the second cutting edge 12 cooperates with the blade 21 to form a cutting of the workpiece 200 to be cut. The opening of the first groove 1011 can ensure the stability and firmness of the connection between the first cutter 10 and the first end 301 of the first knife seat 30. The opening of the second groove 1021 ensures the stability and firmness of the connection between the first cutter 10 and the first end 301 of the first knife seat 30 when the first cutter 10 is separated from the first knife seat 30, turned over and then connected to the first end 301.

[0039] In some embodiments, a connecting portion is protruding from the end surface of the first end 301 , and the connecting portion is inserted into the first groove 1011 or the second groove 1021 to achieve a detachable connection between the first knife holder 30 and the first cutter 10 .

[0040] In some embodiments, reference Figure 3 and Figure 4 The first cutter 10 is provided with a through hole 13 that passes through the first cutter 10 along the second direction Y. The first groove 1011 and the second groove 1021 are connected through the through hole 13. The opening of the through hole 13 can reduce the mass of the first cutter 10 and form a stepped structure inside the first cutter 10 to ensure the stability of the connection between the first cutter 10 and the first cutter seat 30 through the first groove 1011 or the second groove 1021.

[0041] In some embodiments, reference Figures 5 to 7 The end surface of the end 301 of the first knife seat 30 is provided with a mounting groove 303, referring to Figures 6 and 7The first cutter 10 is embedded in the mounting groove 303 to be detachably connected to the first cutter holder 30. The provision of the mounting groove 303 can further improve the assembly stability and firmness between the first cutter 10 and the first cutter holder 30. When the first cutting edge 11 is worn, the first cutter 10 can be removed from the mounting groove 303, turned over, and then installed in the mounting groove 303, so that the second cutting edge 12 cooperates with the blade 21 to perform cutting.

[0042] In some embodiments, reference Figures 5 to 7 The first tool holder 30 includes a first surface 31 and a second surface 32 arranged opposite to each other along the first direction X. Figure 5 and Figure 7 The mounting groove 303 includes a groove bottom 304 and two groove walls 305 arranged opposite to each other along the third direction Z. The two groove walls 305 are respectively provided with receiving portions 306 protruding therefrom. The two sides of the mounting groove 303 arranged opposite to each other along the first direction X respectively penetrate the first surface 31 and the second surface 32. Figure 7 The first cutter 10 is embedded in the mounting groove 303, and the two receiving portions 306 form a receiving portion for the first cutter 10. The second surface 102 of the first cutter 10 abuts against the groove bottom 304. The first cutting edge 11 on the first surface 101 is exposed on the first surface 31, so that the first cutting edge 11 can cooperate with the blade 21 of the second cutter 20 for cutting. After the first cutter 10 is flipped over and installed in the mounting groove 303, the second cutting edge 12 can be exposed on the first surface 31 to cooperate with the blade 21 for cutting.

[0043] In some embodiments, reference Figure 1 as well as Figures 5 to 7 A receiving groove 310 is provided on the first surface 31 of the first knife seat 30. The receiving groove 310 is used to receive the piece 200 to be cut, thereby ensuring the stability of the piece 200 to be cut on the first knife seat 30 and ensuring smooth cutting.

[0044] In some embodiments, reference Figure 2 and Figure 8 The second cutter 20 includes a first end face 201 and a second end face 202 arranged opposite to each other along the first direction X, and the blade 21 includes a first blade 211 and a second blade 212. At least one first blade 211 is provided on the first end face 201, and at least one second blade 212 is provided on the second end face 202. The second cutter 20 can be flipped so that the first blade 211 or the second blade 212 cooperates with the first cutter 10 to form a cutting of the workpiece 200 to be cut.

[0045] In some implementations, the first end face 201 of the second cutter 20 is adjacent to the first cutter 10 along the first direction X, and the first blade 211 on the first end face 201 cooperates with the first cutting edge 11 on the first cutter 10 to perform cutting. As the number of cutting increases, when the first blade 211 wears out and affects the cutting quality and cutting efficiency, the second cutter 20 can be flipped 180° so that the second end face 202 is adjacent to the first cutter 10 along the first direction X, and cutting is performed by cooperating with the second blade 212 on the second end face 202 and the first cutting edge 11 on the first cutter 10, thereby ensuring the cutting quality and cutting efficiency, reducing the number of replacements of the second cutter 20, and reducing the use cost of the cutting device 100.

[0046] In some embodiments, reference Figure 8 The number of the first blades 211 is multiple, and the multiple first blades 211 are spaced apart along the circumferential direction of the first end surface 201 at the edge of the first end surface 201. The second cutter 20 can rotate so that any one of the first blades 211 cooperates with the first cutter 10 to cut the workpiece 200. Figure 8 In the illustrated embodiment, the second cutter 20 is square in shape, the first end face 201 has four sides, and the number of first blades 211 is four. The four first blades 211 are arranged at intervals along the circumferential direction of the first end face 201, and a first blade 211 is provided on each side of the first end face 201. When the second cutter 20 cooperates with the first cutter 10 for cutting, only one first blade 211 cooperates with the first cutter 10 (for example, cooperates with the first cutting edge 11) at a time. Therefore, when the first blade 211 is worn, the second cutter 20 can rotate 90°, 180° or 270°, so that one of the remaining three first blades 211 cooperates with the first cutter 10 to cut the workpiece 200 to be cut, thereby ensuring cutting efficiency and cutting quality.

[0047] In some embodiments, reference Figure 8 The number of the second blades 212 is multiple, and the multiple second blades 212 are spaced apart along the circumferential direction of the second end surface 202 at the edge of the second end surface 202. The second cutter 20 can rotate so that any second blade 212 cooperates with the first cutter 10 to cut the workpiece 200. Figure 8In the illustrated embodiment, the second cutter 20 is square in shape, the cross-sectional shape of the second end face 202 is a quadrilateral, and the second end face 202 has four sides. Accordingly, the number of the second blades 212 is four, and the four second blades 212 are spaced apart along the circumferential direction of the second end face 202. A second blade 212 is provided on each side of the second end face 202. When the second cutter 20 cooperates with the first cutter 10 for cutting, only one second blade 212 cooperates with the first cutter 10 (for example, with the first cutting edge 11) at a time. Therefore, when the second blade 212 is worn, the second cutter 20 can be rotated 90°, 180° or 270°, so that one of the remaining three second blades 212 cooperates with the first cutter 10 to cut the workpiece 200 to be cut, thereby ensuring cutting efficiency and cutting quality.

[0048] Moreover, combined with the design that the second cutter 20 can be flipped, the second cutter 20 can provide a total of eight blades 21 (i.e., four first blades 211 and four second blades 212) to cooperate with the first cutter 10 for cutting, thereby effectively improving the service life of the second cutter 20, reducing the number of times the second cutter 20 is replaced, and reducing the cost of using the cutting device 100.

[0049] In other implementations, the cross-sectional shape of the first end face 201 and the second end face 202 can be a polygon such as a triangle, a pentagon, or a hexagon, so different numbers of first blades 211 and second blades 212 can be selected, and the specific selection can be made according to actual usage requirements.

[0050] In some embodiments, reference Figure 1 and Figure 2 The cutting device 100 further includes a second blade holder 40, which is spaced apart from the first cutter 10 along the first direction X. The second cutter 20 is disposed at one end of the second blade holder 40 along the second direction Y. The second cutter 20 is detachably connected to the second blade holder 40. The second blade holder 40 can drive the second cutter 20 toward or away from the first cutter 10 along the first direction X. The second cutter 20 can be separated from the second blade holder 40 and then connected to the second blade holder 40 after flipping, so that the first blade 211 or the second blade 212 cooperates with the first cutter 10 to cut the workpiece 200. The provision of the second blade holder 40 can ensure the installation stability of the second cutter 20, thereby ensuring cutting stability.

[0051] In some embodiments, the first blade 211 cooperates with the first cutter 10 for cutting, and the second cutter 20 can rotate 90°, 180° or 270° after being separated from the second blade holder 40, so that one of the remaining three first blades 211 cooperates with the first cutter 10 to cut the piece 200 to be cut, thereby ensuring cutting efficiency and cutting quality.

[0052] In some embodiments, the second blade 212 cooperates with the first cutter 10 for cutting. After being separated from the second cutter holder 40, the second cutter 20 can rotate 90°, 180° or 270°, so that one of the remaining three second blades 212 cooperates with the first cutter 10 to cut the piece 200 to be cut, thereby ensuring cutting efficiency and cutting quality.

[0053] In some embodiments, reference Figure 1 and Figure 2 The cutting device 100 also includes a driving member 41 and a pressing block 42.
