[0002] The design of an automatic tension adjustment device for a high sheet resistance composite metallized film slitting machine is mainly to ensure that the film material can maintain stable tension during the slitting process, avoiding material stretching, damage, or uneven cutting. Tension sensors are usually installed in the tension control system of the film material to monitor the tension changes of the film material in real time. The sensors feed back the measured tension data to the control system, providing data support for automatic adjustment.

[0014] (III) Beneficial Effects

[0015] This utility model provides an automatic tension adjustment device for a high sheet resistance composite metallized film slitting machine, which has the following beneficial effects:

[0016] 1. The automatic tension adjustment device of this high square resistance composite metallized film slitting machine, through the setting of the support components, uses a tension sensor to detect the surface tension of the film during use. When it exceeds the set value, the controller controls the telescopic cylinder to push the connecting joint and push rod to rotate, so that the push rod drives the support box to rise and fall. Then, the pressure generated by the tension roller squeezing the film surface causes the rotating shaft to drive the limit rod to press down, the support spring is forced to contract and generate elastic force, thereby offsetting part of the impact generated by tension fluctuations, ensuring the stability and accuracy of tension adjustment.

[0017] The automatic tension adjustment device of this high square resistance composite metallized film slitting machine, through the setting of the limiting component, when the film deviates on both sides during use, the film squeezes the rotating ring, which in turn pushes the limiting plate to squeeze the telescopic spring. At the same time, the positioning rod slides on one side of the positioning ring to keep the movement stable, so that the telescopic spring is compressed by force, which in turn pushes the limiting plate in the opposite direction, thereby offsetting the film's deviation force, realizing dynamic correction, and avoiding material damage caused by film deviation.
