AI Technical Summary

⚠Technical Problem

Existing thermal transfer printers' tensioning mechanisms can only adjust the tension on one side of the driven wheel, making it difficult to prevent the timing belt from tilting and ensuring the parallelism between the timing belt and the printing plane, thus affecting the printing effect.

⚗Method used

A synchronous belt tension adjustment mechanism including a drive mechanism and a driven mechanism was designed. The drive motor drives the drive gear, and the position of the main rotating shaft and the driven gear is adjusted by the screw principle to achieve dual-sided adjustment of the synchronous belt and ensure the stability of the horizontal position of the synchronous belt.

🎯Benefits of technology

It improves the stability of synchronous belt tension adjustment, ensures that the synchronous belt is parallel to the printing plane, and enhances printing results.
