Preferably, a spacer bush is sleeved on the supporting rod between the film and the rolling bearing, and a fastening ring is sleeved on the outer side of the rolling bearing.

Compared with the prior art, the utility model, following positive effect has:

1. the film roll supporting device consists of two sets of rolling supporting structures which are respectively supported at two ends of the film extending out of the film supporting pipe, and the end part of the film supporting pipe extending out of the film is supported in an inner hole of an inner ring of the rolling bearing; on the other hand, the end part of the film supporting pipe extending out of the film is supported in the inner hole of the inner ring of the rolling bearing, so that the radial limiting of the film roll is realized, and the film rolling and unwinding quality is obviously improved.

2. The fixed cover of antifriction bearing outer lane outer wall lower extreme fixed connection, fixed cover threaded connection fixed connection are in the upper end of supporting rod, like this, can adjust change antifriction bearing according to the use needs, satisfy the different diameter's of tip that the film supporting tube stretches out the film demand.

3. The upper end of the supporting rod is provided with a clamping nut and is tightly fixed on the lower end surface of the fixed sleeve. Thus, the fixing sleeve is combined with the supporting rod more firmly.

4. The supporting rod is sleeved with a spacer bush between the film and the rolling bearing, and the outer side of the rolling bearing is sleeved with a fastening ring. Therefore, the film roll is axially positioned on the film roll supporting device, and the film roll unwinding quality is further improved.
