Description

Technical Field

[0001] This utility model relates to a tensioning belt mechanism for a packing machine. Background Technology

[0002] Currently, the tensioning belt mechanism of packaging machines on the market includes a machine body, a drive unit, a feed roller, and a positioning roller. The packaging belt passes around the feed roller, the drive unit drives the feed roller to rotate, and the positioning roller is located next to the feed roller. During operation, when the packaging belt is finished and needs to be cut, the feed roller stops rotating, and the positioning roller moves to the side of the packaging belt to fix the packaging belt on the feed roller, ensuring that the packaging belt will not move during the cutting process. The disadvantage of the above structure is that the positioning roller and the packaging belt are only positioned at one point, the positioning force is not large, and only a small force is needed for the packaging belt to move. The tensioning belt is not fixed, resulting in poor packaging effect. Summary of the Invention
