AI Technical Summary
Existing packaging machines lack automated traction mechanisms, which means that the introduction and extraction of packaging film require manual operation, which is time-consuming and labor-intensive, and the tension cannot be precisely controlled.
A packaging machine film tension control device was designed, which includes a drive traction mechanism and a lifting adjustment mechanism. The device utilizes a drive motor and a rotary gear system to achieve mechanized traction of the packaging film, and adjusts the tension through the cooperation of a lifting plate and a threaded groove.
It enables mechanized introduction and extraction of packaging film, reduces manual operation, improves work efficiency, and allows for precise tension control, thus enhancing the time and labor saving of the operation.
