AI Technical Summary
In ordinary meter-counting thermal printers, the guide belt mechanism is prone to shaking or shifting during use, resulting in unstable printing.
The design employs a double-disc structure, which combines a connecting shaft, a stabilizing disc, a screw, and a stabilizing ring. This allows the guide pulley to be fitted onto the outside of the guide ring seat. The stabilizing ring, through the cooperation of the screw and nut, compresses the guide pulley, ensuring its stable rotation.
This effectively prevents the guide pulley from shaking and shifting, ensuring the stability and accuracy of the printing process.
