AI Technical Summary
The existing packaging machine's film feeding device is insufficient in adjusting the height of the conveyor film roller, resulting in inconvenience and inability to meet different packaging needs.
The film feeding adjustment mechanism includes a reciprocating threaded rod driven by a first motor and a rotating rod driven by a second motor. The height of the film roller is adjusted and transmitted through a sliding screw block and a support connecting rod. Combined with the use of limit blocks and fastening nuts, the stable delivery of the film is ensured.
It enables convenient adjustment and stable transmission of film roller height, improves the ease of use and adaptability of packaging machines, and ensures smooth delivery of packaging film at different heights.
