The using method of the invention has the following working principle:

when the winding roller 2 needs to be arranged between two winding parts, firstly, the limiting ring 4 is movably sleeved on the outer surface of the winding roller 2, then the lower plate 21 and the upper plate 22 are separated from the clamping state, so that the winding roller 2 is placed at the top end of the lower plate 21, then the lower plate 21 and the upper plate 22 are restored to the clamping state, the limiting ring 4 and the limiting plate 3 are aligned and clamped when the winding roller 2 is placed, at the moment, the distance between the two limiting plates 3 can be adjusted through rotating the threaded rod 31, so that the size of the release film 10 is adapted, after the position adjustment of the limiting plate 3 is completed, the clamping rod 32 is pulled outwards to drive the pressing plate 33 to move upwards to the top end of the through hole, then the clamping rod 32 is pushed inwards to be clamped with the through hole, at the moment, the pressing plate 33 is stably arranged, and the pressing plate 33 extrudes the outer membrane 6 at the lower half end of the limiting ring 4, so that the gas in the outer membrane 6 is uniformly distributed in the inner gas pipe 52 along the outer gas pipe 51 and the middle gas pipe 5, and further, each inner membrane 7 is uniformly expanded until the inner membrane 7 is tightly attached to the winding roller 2, therefore, the friction force between the winding roller 2 and the limiting ring 4 is increased, the synchronous rotation of the winding roller 2 and the limiting ring 4 is realized, the long-term dynamic friction between the edge of the release film 10 and the side wall of the limiting ring 4 is effectively avoided, the edge of the release film 10 is protected from being damaged, and the quality of a finished product after winding is improved;

because the pressure plate 33, the connecting block 63 and the inner air tube 52 have the same magnetism, and the outer air tube 51 and the inner air tube 52 have different magnetism, when the winding roller 2 is driven by the motor assembly 23 to rotate the limiting ring 4, the outer membrane 6 rotates and is close to the pressure plate 33 and the outer air tube 51, the connecting block 63 is effectively pushed to move towards the limiting ring 4, the outer membrane 6 is further promoted to contract inwards, the friction force between the outer membrane 6 and the pressure plate 33 is reduced, the rotation resistance of the limiting ring 4 is further reduced, and the stability of the limiting ring 4 in rotation is effectively improved;

because the pressing plate 33 limits the lower sealing block 81 and the upper sealing block 82, the lower sealing block 81 and the upper sealing block 82 are always kept in an immovable state and do not move due to the rotation of the limiting ring 4, therefore, the space in the limiting ring 4 is divided into four parts by the lower sealing block 81, the upper sealing block 82, the outer sealing plate 9 and the inner sealing plate 91, when the limiting ring 4 rotates anticlockwise, the volume of the four spaces is changed, the air pressure in the space is changed, when the space is in a negative pressure state, air is supplemented from the outer side by the one-way air valve 41, and the edge of the release film 10 is adsorbed, so that the release film 10 is paved, and the flatness of the release film 10 is further improved.
