7. The automatic packaging device for a grinding head according to claim 1, characterized in that: The cloth clamping structure is provided with a clamping fixing part and a bracket. The clamping fixing part is fixedly connected to the base plate, and the clamping fixing part is provided with a guide groove. The bracket is swingably connected to the guide groove. The bracket is provided with a hook. The cloth can be fixedly connected to the hook and is swung and flattened by the bracket for the grinding head to abut.

8. A working method of a grinding head automatic packaging device, characterized in that: An automatic grinding head packaging device according to any one of claims 1 to 7, comprising the following steps: S1: After setting the zero position of the fixture drive electric cylinder, place the grinding head on the grinding head clamping structure and the fabric on the fabric clamping structure; S2: The inching fixture drives the electric cylinder to drive the grinding head clamping structure to move upward. The grinding head continues to move after it contacts the fabric. When the grinding head lifts the fabric to a suitable distance, it stops and records the distance from zero position to fabric lifting. S3: measurement is completed, return to the original position, and set the program parameters; S4: According to the setting, the grinding head clamping structure is driven. After the grinding head lifts the cloth, the feeding structure is started to extrude the rod. According to the extrusion length, the program sets the time difference to drive the bending structure. The first bending tool and the second bending tool cooperate to wrap the rod around the cloth and the grinding head. The shearing structure extends, and the first bevel part and the second bevel part on the first shearing tool and the second shearing tool cut off the rod, clamp the rod head port and tighten the rod, and wrap the cloth together at the same time.
