[0034] The bottom of the electric slider is fixedly connected to the connecting plate 11, and the cutter 12 is fixedly installed on the bottom of the connecting plate 11.

[0035] Using the aforementioned precision cutting mechanism, the left side of the nonwoven fabric 3 comes into contact with the inner wall of the left side of the hole. The hydraulic cylinder 5 is activated, and the pressure plate 8 presses and fixes the nonwoven fabric 3. Then, the electric slider is activated, and the cutting scissors 12 cut the fixed nonwoven fabric 3. This method allows for convenient and quick cutting of the nonwoven fabric 3 to a fixed length, making the operation relatively easy.

[0036] Specifically, the precision cutting mechanism also includes a cross frame 13, a positioning rod 14, and a positioning hole 15.

The positioning rod 14 and the positioning hole 15 are engaged.

[0037] With the aforementioned precision cutting mechanism, when the cutting length needs to be adjusted, the hydraulic cylinder 5 is activated, causing the pressure plate 8 to move into the fitting groove 16. At this time, the positioning rod 14 moves out of the positioning hole 15, and then the sleeve plate 9 is moved laterally to adjust the position of the cutting blade 12. After the adjustment is completed, the hydraulic cylinder 5 is activated, causing the positioning rod 14 to move upward and engage in a positioning hole 15.

[0038] Specifically, the two placement racks 2 are respectively provided with hole one and hole two. Non-woven fabric 3 is placed in hole one and hole two. The bottom of the pressure plate 8 abuts against the non-woven fabric 3. The side of the non-woven fabric 3 contacts the inner wall of the left side of hole one.

The top of the horizontal frame 13 has a square hole, and the main frame 6 is slidably installed in the square hole. It should be noted that this facilitates the stable vertical movement of the auxiliary frame 7 and the main frame 6.

[0041] Working principle:

[0042] S1: The left side of the non-woven fabric 3 is brought into contact with the inner wall of the left side of the hole body. The hydraulic cylinder 5 is activated, which causes the main frame 6 to move the auxiliary frame 7 downward. The auxiliary frame 7 moves the pressure plate 8 downward. The pressure plate 8 presses and fixes the non-woven fabric 3. Then the electric slider is activated, which causes the connecting plate 11 to move the cutting scissors 12. The cutting scissors 12 cuts the fixed non-woven fabric 3. This makes it convenient and quick to cut the non-woven fabric 3 to a fixed length, and the operation is relatively convenient.

[0043] S2: When the cutting length needs to be adjusted, start the hydraulic cylinder 5 so that the pressure plate 8 moves into the adapter groove 16. At this time, the positioning rod 14 moves out of the positioning hole 15. Then, move the sleeve plate 9 laterally to adjust the position of the cutting shears 12. After the adjustment is completed, start the hydraulic cylinder 5 so that the positioning rod 14 moves up and gets into a positioning hole 15. This makes it easy to adjust the cutting length. When cutting the non-woven fabric 3 later, the non-woven fabric 3 can be quickly cut to a fixed length.

[0044] The above provides a detailed description of the nonwoven fabric precision cutting device provided by this utility model.
