[0025] Example 1

[0026] See also Figure 1-Figure 3 In an embodiment of the utility model, a multi-blade line film cutting knife fixing device includes a knife seat 1, a limiting groove 2 is provided in the upper and middle part of the knife seat 1, a first cutting knife 3 is provided above the knife seat 1, a second cutting knife 4 is slidably connected inside the first cutting knife 3, a lifting component for adjusting the height of the second cutting knife 4 is provided on the first cutting knife 3 and the second cutting knife 4, a fixing component for fixing the first cutting knife 3 is provided at the bottom of the first cutting knife 3, and a moving component for moving the fixing component is provided inside the limiting groove 2.

[0027] In one embodiment, Figure 1 and Figure 2 As shown, the lifting assembly includes a first threaded hole 5, which is opened on one side of the first cutter 3, and a second threaded hole 6 is provided on one side of the second cutter 4. The first threaded hole 5 and the second threaded hole 6 are spirally connected with a first bolt 7. By rotating the first bolt 7, the second cutter 4 can slide up and down inside the first cutter 3. When the second cutter 4 moves to a suitable position, it is fixed by rotating the first bolt 7.

[0028] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the fixing assembly includes a tool holder 8, the top of which is fixedly connected to the bottom of the first cutting knife 3, and a third threaded hole 9 is formed around the tool holder 8. The third threaded hole 9 is spirally connected to a second bolt 10, and the tool holder 8 is fixed or released by rotating the second bolt 10.

[0029] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the moving assembly includes a motor 11, which is fixedly connected to one side of the tool holder 1, and a reciprocating screw 12 is fixedly connected to the output end of the motor 11. The two sides of the reciprocating screw 12 are rotatably connected in the limit groove 2, and a limit rod 13 is fixedly connected in the limit groove 2. The reciprocating screw 12 is threadedly connected to the inside of the slider 14, and the inside of the slider 14 is slidably connected to the limit rod 13. The top of the slider 14 is movably abutted against the tool holder 8, and a fourth threaded hole 15 is provided around the slider 14. By starting the motor 11, it drives the reciprocating screw 12 to rotate, and the reciprocating screw 12 will drive the slider 14 to rotate. Due to the existence of the limit rod 13, the slider 14 can only move horizontally, and the limit groove 2 limits the slider 14, and the slider 14 will drive the tool holder 8 to move together.

[0030] In one embodiment, Figure 2 As shown, the tool holder 1 is movably connected to the tool shaft 16, a fifth threaded hole 17 is opened on one side of the tool holder 1, and a sixth threaded hole 18 is opened on one side of the tool shaft 16.

[0034] In one embodiment, Figure 3 As shown, the fourth threaded hole 15 cooperates with the third threaded hole 9 , so that the second bolt 10 can rotate at the third threaded hole 9 and the fourth threaded hole 15 .

[0035] The working principle of the utility model is as follows: the above embodiment discloses a multi-knife line film cutting knife fixing device, wherein the locking bolt 19 is rotated to reach the fifth threaded hole 17 and the sixth threaded hole 18, so that the knife seat 1 and the knife shaft 16 are fixed together, and then the first bolt 7 is rotated to make the second cutting knife 4 slide up and down inside the first cutting knife 3. When the second cutting knife 4 moves to a suitable position, the first bolt 7 is rotated to fix it, and then the second bolt 10 is rotated to reach the third threaded hole 9 and the fourth threaded hole 15, so that the knife holder 8 can be fixed on the slider 14. After cutting one place, the motor 11 is started to drive the reciprocating screw rod 12 to rotate, and the reciprocating screw rod 12 will drive the slider 14 to rotate. Due to the existence of the limit rod 13, the slider 14 can only move horizontally, and the limit groove 2 limits the slider 14, and the slider 14 will drive the knife holder 8 to move together.

[0036] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
