Therefore, the winding film tension adjusting device can pre-stretch the winding film 5 before packing the product, ensures that the winding film 5 has enough winding force and enough retraction under any condition, and can stably and tightly wrap the product during packaging, so that the packaging appearance is more compact and transparent.
As shown in fig. 1 and 2, the wrapping film tension adjusting apparatus further includes a frame 10, and the above-mentioned drive roller 8 and driven roller are rotatably mounted on the frame 10 by a connecting shaft 9 thereon so that both the drive roller 8 and the driven roller can freely rotate on the frame 10. In addition, the driving roller 8 is driven by the motor 17 to rotate, so that the clockwise rotation can accelerate the winding film 5 to the packing machine 13, and the speed can be reduced or the reverse rotation can pull the winding film 5 to increase the tension. The tension sensing roller 7 is also rotatably mounted on the frame 10 through connection shafts at both ends, and a roll surface thereof can measure the tension of the winding film 5 wound thereon, and the tension sensing roller 7 is also electrically connected to the controller 8 to transmit detected data as a detection signal to the controller 8.
