[0002] Non-woven fabric is a material produced from polyester fiber and polyester fiber materials and made through a needling process. Different thicknesses, hand feelings, hardnesses, etc. can be made through the production process. Due to the characteristics of non-woven fabric such as moisture-proof, sound-insulating, heat-insulating, breathable, low cost, and recyclable, most industries now use non-woven fabric as a processing material to produce non-woven fabric semi-finished products corresponding to the required needs.

[0003] The patent "A non-woven fabric production line with stable winding and precise cutting" with the authorization announcement number of CN218707918U can drive the blade to cut the non-woven fabric through a clamp. However, many existing enterprises have more than just a single size and shape requirement for non-woven fabrics. In various fields and industries, non-woven fabrics of various sizes are required for further processing. Therefore, before processing, a device that can precisely cut non-woven fabrics is needed to meet the cutting requirements of different sizes. Summary of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A precise cutting device for non-woven fabrics includes a workbench, a cutting plate fixedly connected to the workbench, a cutting tool installed on the workbench, a cutting assembly that moves along the length direction of the cutting plate on the cutting plate, and a first moving mechanism that drives the cutting tool to move along the width direction of the cutting plate inside the cutting assembly;

[0007] A moving support is installed on the workbench along the length direction of the cutting plate, at least two pressing blocks are installed on the moving support, and a second moving mechanism that drives the pressing blocks to move along the length direction of the workbench is provided on the moving support.

[0008] Further, the first moving mechanism includes a first guide rail installed on the workbench, and the first guide rail is connected to the cutting assembly.

[0009] Further, the cutting component includes a moving plate connected to the first guide rail. A third guide rail is installed on the moving plate, and a moving slider is connected to the third guide rail. The cutting tool is fixedly connected to the moving slider.

[0010] Further, the second moving mechanism includes a second lead screw rotatably connected inside the workbench, and the second lead screw is threadedly connected to the moving bracket.

[0011] Further, a fixed frame is fixedly connected to the moving bracket. A first lead screw is installed on the fixed frame, and a moving bushing is threadedly connected to the first lead screw. A second guide rail is installed below the moving bushing, and a pressing block is installed on the second guide rail.

[0012] Further, a pneumatic telescopic rod is provided inside the pressing block.

[0013] Further, pulleys for facilitating movement are installed below the workbench.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] First, through the first moving mechanism, the movement of the cutting tool can be driven, and through the third guide rail, the cutting tool can adjust its own position during the movement, so that the cutting angle can be variable, rather than simply cutting out vertical and horizontal incisions.

[0016] Second, through the second moving mechanism, the position of the pressing block can be driven to adjust to fix the non-woven fabric to be cut, ensuring the accuracy of cutting. And by adjusting the position of the pressing block, it can also better ensure that the cutting tool does not exceed the range controlled by the pressing block. BRIEF DESCRIPTION OF THE DRAWINGS
