The Mx177 is a wrapping machine for tissue paper reels characterized by a rolls group positioned under the floor level and by a structure over the floor level which supports the rotating arm.
The wrapper is constituted by a single column and by the rotating arm support.
The support of the rotating arm is a heavy carpentry bracket which moves vertically on the column by means of a hydraulic piston.
Inside the bracket are installed all drives which need to move and to control the rotating arm.
The bottom part of the structure is ready for the installation of the film “cut and hold” group for the automatic management of the wrapping cycle (optional).
At the end of the rotating arm is installed the film holder threaded on the tubular structure: this solution permits easier maintenance and substitution actions.
On the film holder are located the plastic films roll supporting systems, the tension control by means of an hydraulic breaker located in correspondence of the guiding roll and the film breakage detector.
The machine basement is constituted by the rolls group which turns the reel during the wrapping action; the group is composed by a main structure which supports two oscillating flats equipped with a winding roll and a neutral roll each one. Flaps are both hinged on center line of the main structure and each flap is lifted by a couple of hydraulic pistons. Flaps are concurring to form a “V” shape which keeps the reel centered on the rolls group.
Flaps lifting system allows to vary the height of each flap independently: in this way it is possible to do following operation
• to stop the reel in arrival.
• to push out the reel from the machine at the end of the cycle.
• to vary the distance between the centres of the rolls in order to adapt the shape of rolls group to reel’s diameter.
The main structure is fixed on the floor by means of chemical bolts and supports are ready to be equipped with loading cells (optional).
