The feeding assembly is used to drive the cloth forward, and the cutting assembly is used to cut off part of the cloth. In this application, the shape of the movable knife part is cut through the matching movable knife 33 and the stationary knife 31. It can be various shapes such as round, oval, rectangular, etc. One end of the ball head connector is connected to the second power source, and the other end is matched with the spherical surface of the movable knife and installed together, which greatly reduces the installation accuracy requirements. Furthermore, the stationary knife 31 is provided with a cutting hole that matches the movable knife 33, and the movable knife and the stationary knife are provided with blades on the opposite surfaces to cut the cloth when the two are in contact.

[0022] In this embodiment, as shown in the figure, the frame is further provided with a cutter guide seat 4. Within the cutter guide seat is a guide slot 41 disposed opposite the stationary cutter, within which the movable cutter is disposed. A cutting hole in the stationary cutter is coaxial with the guide slot for guidance, and the movable cutter moves up and down within the guide slot.

[0023] In this embodiment, as shown in the figure, the outer wall of the cutter guide seat is provided with a sink 42 for placing the cloth. The cloth can move along the sink, which plays a certain guiding role.

[0024] In this embodiment, as shown in the figure, the movable blade is provided with a groove 331, and the ball connector includes a spherical surface 321 and a flat surface 322. The bottom of the groove is a second spherical surface that matches the spherical surface. A retaining spring 332 is also installed in the groove. The retaining spring cooperates with the flat surface to prevent the ball connector from falling out. One end of the ball connector extends into the groove, and its spherical surface cooperates with the arcuate surface (preferably a spherical surface) at the bottom of the groove to allow for a certain angle of rotation. The flat surface at its lower end is blocked by the retaining spring, preventing the ball connector from falling out of the groove. The second power source can be a cylinder, and its drive rod and the ball connector rod can be connected by a coupling. Alternatively, a mounting hole can be provided at the bottom of the ball connector for mounting the drive rod.

[0025] In this embodiment, as shown in the figure, the static knife is detachably mounted on the upper end surface of the cutter guide seat and can be fixedly mounted by screws or the like.

[0026] In this embodiment, as shown in the figure, the first power source is a motor.

[0027] In this embodiment, as shown in the figure, the second power source is a cylinder.

[0028] In this embodiment, as shown in the figure, the cutting assembly is provided with two in the horizontal direction. Both sides can be operated simultaneously, which is more efficient.

[0029] In this embodiment, as shown in the figure, the frame is provided with a guide rail 11, the guide rail is provided with a sliding mounting plate 12, the second power source is mounted on the mounting plate, and the cutter guide seat is mounted on the second power source or the mounting plate. The position of the cutter seat can be adjusted.

[0030] In this embodiment, as shown in the figure, the mounting plate is provided with an adjustment seat 13, which is provided with a threaded hole and an adjustment screw 14. The middle end of the adjustment screw engages with the threaded hole, and one end of the adjustment screw is provided with a handwheel 15 for manual operation. When the adjustment screw on the adjustment seat is rotated, it drives the adjustment seat to move laterally, which in turn drives the mounting plate to move, causing the components mounted on the mounting plate to move accordingly. The handwheel is used to manually rotate the adjustment screw to achieve adjustment.
