In roller cutting, a series of rollers are usually used to convey the material to the cutting machine, and the material is cut into the required shape and size by the cutting tool. The role of the positioning device is to ensure that the material being cut maintains a stable position during the cutting process to ensure the accuracy and consistency of the cutting.

[0003] The existing patent (publication number: CN207467794U) proposes a roller positioning device, including a positioning body, a first roller shaft hole is opened at the top of the positioning body, a second roller shaft ring is arranged in the middle of the positioning body, a third roller shaft hole is arranged at the bottom end of the positioning body, a first groove is arranged on the first roller shaft hole, a third groove is arranged on the third roller shaft hole, washers are arranged on the first groove and the third groove, the second roller shaft ring is composed of an arc ring and a fastening plate, the fastening plate is provided with screw holes, which can meet the needs of rollers of different sizes, is more practical and saves costs.

[0004] However, the existing roller positioning devices usually do not firmly fix the roller during positioning and cutting. The loose fixation of the roller will cause the position of the cutting tool to be unstable, thereby reducing the cutting accuracy and causing vibration or vibration during the cutting process, which will affect the stability of the cutting tool and thus reduce the cutting quality. The loose roller will move or tilt during the cutting process, increasing the risk of accidents. Therefore, the utility model proposes a positioning device for roller cutting processing to solve the above problems. Utility Model Content
