[0002] The tension adjustment mechanism for tape production is a crucial equipment in the tape production process. It is mainly used to control the tension of the tape during the conveying process to ensure the quality and production efficiency of the tape.
[0003] Although setting a tension adjustment roller and multiple guide rollers can adjust the tension of the tape and guide the tape, since the tape generally has one smooth side and the other sticky side, this setting will inevitably cause the guide roller to contact the sticky surface of the tape. Even if the glue has been cooled, the contact friction between the guide roller and the guide roller may still scrape off some of the glue, or the dust on the guide roller may contaminate the glue, resulting in affecting the adhesion effect of the glue on the tape. For this reason, the utility model provides a tension adjustment mechanism for tape production. Utility Model Content

Thus, when the tension of the adhesive tape can be adjusted, there is no need to contact the adhesive surface of the adhesive tape, thereby avoiding the situation where the guide roller scrapes off part of the glue or the dust on the guide roller contaminates the glue.
[0015] (2) The tension adjustment mechanism for the tape production drives the rotating plate to rotate with the rotating shaft as the center by starting the electric push rod. The rotating shaft drives the connecting plates on both sides to move synchronously, thereby synchronously driving the winding drum and the adjusting roller to move in opposite directions. When the tape needs to be tightened, the winding drum moves upward and the adjusting roller moves downward. When the tape needs to be loosened, the winding drum moves downward and the adjusting roller moves upward, thereby improving the efficiency of the tape tension adjustment.
