Existing plastic sheeting wrap-up is generally single station or double mechanism, and its use is inconvenient, efficiency ratio is lower, and the uropatagium waste material on the finished product volume is too many, need manually shut down useless film, and film gas enclosure situation is serious, is not easy to realize automated production.

The utility model content

But the technical problems to be solved in the utility model provide a kind of automatic winding and efficient higher be used for three wrap-ups on the full-automatic plastic film take-up machine.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of three wrap-ups that are used on the full-automatic plastic film take-up machine, its gordian technique is: it is positioned between left and right two wallboards of winder, it comprises two rotating disks that are installed on respectively on left and right two wallboards, be provided with the center transmission shaft and be located at axial three of center transmission between two rotating disks and be 120 ° of well-distributed Scroll A axles, B axle and C axles in twos, described A axle, B axle and C axle lay respectively at preparation station, rolling station and unload the volume station;

At the supporting first position-movable touch roll that is provided with through air cylinder driven of the A of described preparation station axle sidepiece, at the supporting second position-movable touch roll that is provided with through air cylinder driven of the B of described rolling station axle place left upper portion, the supporting position-movable protection roller that is provided with through air cylinder driven in upper lateral part position, the B of described rolling station axle place; Supporting first touch roll that is provided with of described A axle sidepiece, described B axle sidepiece is provided with second touch roll, also be provided with between left and right two wallboards and be used for deflector roll that plastic sheeting is led, described plastic sheeting is wound on the B axle behind space between deflector roll, first touch roll and the A axle; Also comprise a cutting knife that is used to cut off plastic sheeting of installing with the rotating shaft coaxle of second touch roll.

During the utility model rolling, described plastic sheeting is wound on the B axle after between deflector roll, first touch roll and the A axle, this moment second touch roll and the B axial compression is closed and protect roller also to close with the B axial compression; During change of lap, the finished product plastic sheeting that is cut off by cutting knife is wound on the B axle, the film that continues rolling is wound on the A axle, this moment described rotating disk clickwise, the B axle arrives the residing volume station that unloads of former C axle, first touch roll and the rotation of A axis clamping plastic sheeting rise to fixed position, second touch roll rotation meanwhile presses down and engages the plastic sheeting that is wound on the A axle, rotate to the residing rolling station of former B axle until the A axle, first touch roll contrarotation this moment is got back to initial position and is closed with the C axial compression that rotates to herein.

Adopt the beneficial effect that technique scheme produced to be: the utility model takes turns rolling by three Scrolls that are provided with, rotating disk rotation during change of lap, and then the position of A axle, B axle and C axle is changed, by having converted rolling and unloaded volume of three kinds of stations, work efficiency improves greatly.And the no tailing in finished product volume surface produces, and this is that the no tailing of rotating disk rotation has had tailing if rotating disk changes just to cut earlier again then owing to the finished film volume that is positioned at the B axle is to be cut off by cutting knife when normal working.Superior product quality, consumption reduce production costs less.
