[0001] This application relates to the field of cutting technology, and more particularly to a fabric cutting device. Background Technology

[0002] Fabrics used in clothing or other applications need to be cut into the required shapes, such as circles or squares, or slit during the production process. Among these shapes, circles are the most difficult to cut. If they are slit manually by workers, errors and irregular shapes are likely to occur. Utility Model Content

[0003] The purpose of this application is to provide a fabric cutting device to solve the technical problems of errors and irregular shapes that easily occur during manual cutting in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a fabric cutting device is provided, including a fixed disc; a fixed shaft assembly is provided in the middle of the fixed disc; a movable part is provided on the fixed disc for movable positioning; the movable part cooperates with the cutting part; the movable part is limited by the fixed shaft assembly; a transverse notch is provided on the fixed disc, the transverse notch divides the fixed disc into two independent semicircular blocks; a transverse plate is provided below one end of the transverse notch; the fixed shaft assembly connects the two semicircular blocks.

[0005] With the above technical solution, the fabric to be cut is laid flat on the table, and then the entire cutting device is placed on top of the fabric. By rotating the fixed disc around the fixed axis, the blade on the cutting part cuts the fabric, thus cutting out a regular circular piece of fabric.

[0007] With the above technical solution, the top plate is used to connect two semicircular blocks and raise them upwards. The fixed shaft and the fixed tube are sleeved together. The fixed shaft is located inside the fixed tube, and the fixed tube rotates relative to the fixed shaft. By setting an annular protrusion on the fixed shaft and an annular groove inside the fixed tube, the relative rotation and axial limit of both can be achieved.

[0013] With the above technical solution, the scale is used to display and calculate the distance from the center of the fixed axis, that is, the radius of the circular fabric to be cut. The cutter head is a blade structure, and the rollers on the mounting bracket facilitate the rotation of the entire fixed disc and reduce friction.

[0014] Optionally, the upper end of the mounting base is provided with a disk; the disk is provided with a pointer; the pointer is opposite to the scale; the diameter of the disk is greater than the width of the upper end of the mounting base; the upper end of the disk is located in the strip-shaped through hole.
