Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a non-woven fabric cutting device. Background Art

[0002] Non-woven fabric is a non-woven fabric that directly uses polymer chips, short fibers or filaments to form a web through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally undergoes post-processing to form a non-woven fabric. It has the advantages of fiber scraps, strength and durability. Non-woven fabrics generally appear in the factory in the form of rolls, and then are processed again through a cutting device.

[0003] When the existing mechanism is cutting, the cutting knife cuts the non-woven fabric from one direction. When the non-woven fabric contacts the cutting knife, the cutting part is pressed downward, causing bending on both sides of the cut, which in turn leads to uneven cuts and affects the cutting quality of the fabric. Therefore, a non-woven fabric cutting device is proposed to solve the above-mentioned problems. Utility Model Content

[0008] The beneficial effect of the utility model is that: according to the required cutting length, the first push rod pushes the pressing frame to press and fix the non-woven fabric, and then the second push rod pushes the cutter to move downward, and the non-woven fabric pressed by the pressing frame is cut through the through hole, thereby preventing the non-woven fabric of the cutter from bending on both sides during cutting, which leads to uneven cutting.

[0009] The non-woven fabric cutting device has the advantage of neat cutting.

[0012] The beneficial effect of adopting the above further solution is that the non-woven fabric can be clamped between the transmission roller and the pressing roller by pressing the pressing roller downward through the spring, thereby preventing the non-woven fabric from slipping during transmission.

[0013] Furthermore, the pressing roller is slidably connected to the inner side of the second fixed frame, and the pressing roller has the same width as the transmission roller.

[0014] The beneficial effect of adopting the above further solution is that the pressing roller is slidably connected to the second fixed frame, so that the pressing roller can slide up and down stably inside the second fixed frame. The pressing roller and the transmission roller have the same width, which facilitates the smooth transportation of the non-woven fabric.

[0015] Furthermore, a motor is fixedly installed on the front of the workbench, and the output end of the motor is fixedly connected to the transmission roller.

[0016] The beneficial effect of adopting the above further solution is that the transmission roller can be driven to rotate by the motor to transport the cloth.

[0017] Furthermore, a cutting groove is provided on the top of the workbench, and the cutting groove is located below the cutting knife.

[0018] The beneficial effect of adopting the above further solution is that the non-woven fabric can be cut easily by cooperating with the cutter through the cutting groove.

[0019] Furthermore, a through hole is fixedly installed on the bottom of the pressing frame, and the size of the through hole is adapted to the cutter.

[0020] The beneficial effect of adopting the above further solution is that the through hole facilitates the cutter to pass through the pressing frame to cut the non-woven fabric. BRIEF DESCRIPTION OF THE DRAWINGS
