Film delivery following up mechanism

The film delivery following up the rotary arm rotating, the proximity switch control the start/stop of film delivery motor to follow up the rotary arm

Film auto feeding and cutting device                          1set

When stretch wrapping finish, the film will be cut and clamped automatically.

When the film tail is released from the clamp, the air shooter will blow the film tail up, then the film tail will be wrapped by stretch film and keep it tightly with the pallet to ensure no film tail produced.

Film hot melt cutting adopts electrical heating wire to cut the film.

After film being cut, the hot sealer will seal the film tail automatically to ensure no film tail come out.
