[0002] In the production process of expanded raw material tape, the cutting process is a crucial step.

[0003] Traditional cutting tools typically have straight cutting edges. When cutting expanded raw material tape, the cutting force tends to fluctuate significantly due to the material properties of the raw material tape (such as softness and elasticity). This leads to an unstable cutting process and problems such as uneven cuts and rough edges, which affect the product quality of the raw material tape. Utility Model Content

[0004] In view of the technical problems mentioned in the background art, this utility model provides a cutting tool for producing expanded raw material tape.

[0005] The technical solution adopted by this utility model is: a cutting tool for producing expanded raw material tape, including a tool holder, a cutting blade detachably and fixedly connected to the bottom of the tool holder, and multiple sets of arc-shaped grooves at the bottom of the cutting blade, with breaking teeth between two adjacent arc-shaped grooves, and an annular cutting edge inside the arc-shaped grooves; in the above technical solution, the raw material tape is cut by the cutting blade, and due to the setting of multiple sets of arc-shaped grooves, the raw material tape is first pierced by the breaking teeth during the cutting process, and then fully cut by the annular cutting edge. Thus, the design of arc-shaped grooves and annular cutting edge effectively reduces the fluctuation of cutting force, making the cutting process more stable, and can accurately control the cutting position and angle, thereby ensuring the edge quality of the expanded raw material tape after cutting.

[0006] A further feature of this invention is that the cutting blade has a heat dissipation groove inside, and a heat-conducting sheet is fixedly connected inside the heat dissipation groove.

[0007] A further feature of this invention is that the heat-conducting sheet is a semiconductor refrigeration sheet.

[0008] A further feature of this invention is that the top side of the cutting blade is provided with an insertion hole, and an insertion plate is provided through the blade holder, the insertion plate being inserted into the insertion hole.

[0009] A further feature of this invention is that the top two sides of the insert plate are provided with positioning holes, and a limiting plate is inserted into the positioning holes.

[0010] A further feature of this invention is that a connecting rod is rotatably connected to the outside of the insert plate, one end of the connecting rod is threadedly connected to a positioning bolt, and a threaded hole is provided at the position of the positioning bolt corresponding to the limiting plate.

[0011] A further feature of this invention is that the cutting blade has a V-shaped structure.

[0012] The beneficial effects of this utility model are as follows: In this utility model, the raw material strip is cut by a cutting blade. Due to the setting of multiple sets of arc grooves, during the cutting process, the raw material strip is first pierced by the crushing teeth, and then fully cut by the annular cutting blade. The design of the arc groove and the annular cutting blade effectively reduces the fluctuation of the cutting force, making the cutting process more stable and enabling precise control of the cutting position and angle, thereby ensuring the edge quality of the expanded raw material strip after cutting.

[0023] In the description of this utility model, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0025] In order to solve the problems existing in the background art, this application proposes the following technical solution: a cutting knife for producing expanded raw material tape, including a knife holder 7, and a cutting knife 1 is detachably and fixedly connected to the bottom of the knife holder 7. The cutting knife 1 has a V-shaped structure.

[0026] In this embodiment, the top side of the cutting blade 1 is provided with an insertion hole 13, and an insertion plate 9 is provided through the blade holder 7. The insertion plate 9 is inserted into the insertion hole 13. Positioning ports 12 are provided on both sides of the top of the insertion plate 9. Limiting plates 8 are inserted into the positioning ports 12. A connecting rod 10 is rotatably connected to the outside of the insertion plate 9. One end of the connecting rod 10 is threadedly connected to a positioning bolt 11. The positioning bolt 11 is provided with a threaded hole at the position of the limiting plate 8. When disassembling and replacing the cutting blade 1, it is only necessary to rotate and remove the positioning bolt 11, and take out the limiting plate 8 and the insertion plate 9, thereby removing the cutting blade 1 from the blade holder 7. Pull it out and replace it with a new cutting blade 1. In this embodiment, multiple sets of arc-shaped grooves 4 are provided at the bottom of the cutting blade 1. There are breaking teeth 5 between two adjacent arc-shaped grooves 4. There is an annular cutting blade 6 in the arc-shaped groove 4. During the cutting process, the raw material strip will be pierced by the breaking teeth 5 first, and then fully cut by the annular cutting blade 6. The design of arc-shaped grooves 4 and annular cutting blade 6 effectively reduces the fluctuation of cutting force, makes the cutting process more stable, and can accurately control the cutting position and angle, ensuring the edge quality of the expanded raw material strip after cutting.

[0027] In order to dissipate heat from the cutting blade 1, a heat dissipation groove 2 is provided inside the cutting blade 1. A heat-conducting plate 3 is fixedly connected inside the heat dissipation groove 2, and the heat-conducting plate 3 can be a semiconductor cooling plate or other heat-conducting plate 3.

[0028] The usage method of this embodiment is as follows:

[0029] The cutter holder 7 is connected to the cutting equipment, which drives the cutter holder 7 and the cutting blade 1 to move up and down, thereby cutting the raw material strip. Due to the setting of multiple sets of arc grooves 4, during the cutting process, the raw material strip is first pierced by the crushing teeth 5, and then fully cut by the annular cutting blade 6. The design of the arc grooves 4 and the annular cutting blade 6 effectively reduces the fluctuation of cutting force, making the cutting process more stable, and can accurately control the cutting position and angle, ensuring the edge quality of the expanded raw material strip after cutting.

[0030] In addition, when it is necessary to disassemble and replace the cutting blade 1, simply rotate to remove the positioning bolt 11, take out the limiting plate 8 and the insert plate 9, thereby pulling the cutting blade 1 out of the blade holder 7, and then replace it with a new cutting blade 1.
