The disc type indentation knife is adopted and the annular edge is arranged, so that the damage to the surface of the base cloth can be avoided by utilizing the rolling principle, and the impact of the indentation effect caused by the occurrence of folds in the indentation process is avoided. For the cylindrical surface of the drum, a smooth surface structure can be adopted, in this case, for better matching with the annular blade, an annular groove 41 corresponding to the annular blade is formed on the cylindrical surface of the drum 4. The annular groove 41 can play a role in guiding, so that the indentation cutter 8 can be prevented from slipping, and the indentation effect is further ensured.
Referring to the drawings, a plurality of guide rollers 32 are rotatably mounted on a frame 1, two limit collars 33 are respectively sleeved on each guide roller 32 and a rotary drum 4 at intervals, and fastening bolts 34 are mounted on the limit collars 33. The guide roller 32 is used for conveying cloth, and avoids the cloth wrinkling deformation. The two limiting collars 33 are used for limiting at two sides of the width direction of the cloth, so that the cloth is prevented from deflecting in the conveying process, and the indentation effect is further ensured.
In summary, the present invention is not limited to the above embodiments. Several changes or modifications may be made by one skilled in the art without departing from the spirit and scope of the invention. Such changes and modifications fall within the scope of the present invention.
