When the film roll on the outer surface of the inflatable shaft 301 moves in the transverse direction, the position sensor 513 detects that the position of the film roll changes in the transverse direction, at this time, the first driving cylinder 106 is started and drives the right supporting seat 209 to move in the top transverse direction of the supporting base 101, the synchronous belt is used for driving the inflatable shaft 301 to move in the transverse direction when the right supporting seat 209 moves, and the inflatable shaft 301 is used for driving the film roll to move in the transverse direction when moving in the transverse direction, so that the position of the film roll is adjusted, the position sensor 513 detects the position of the film roll at the moment, and the stability and unreeling efficiency of the film roll in the unreeling process are further improved.
When the inflatable shaft 301 rotates and drives the film roll to rotate to vibrate, one end of the inflatable shaft 301 is in extrusion contact with the bottom of the extrusion plate 518, when the inflatable shaft 301 vibrates, the vibration damping and buffering effects on the inflatable shaft 301 are further improved by means of the elastic property of the vertical expansion pipe 517 and the extrusion contact of the extrusion plate 518 on the inflatable shaft 301, and the change of the position of the outer surface film roll caused by the overlarge vibration amplitude of the inflatable shaft 301 is avoided, so that the stability and the vibration damping performance of the inflatable shaft 301 are improved.
When the film roll on the outer surface of the air expansion shaft 301 is unreeled and needs to be subjected to a roll changing process, the second driving cylinder 212 is started and drives the bottom piston to move upwards to be separated from the upper limit groove 307, the left bearing seat 302 is separated from the limit state, the first driving motor 208 is started and drives the bottom upper connecting shaft 205 to rotate, the upper connecting shaft 205 is in limit insertion connection with the upper limit groove 303 when rotating, the right bearing seat 306 rotates outwards around the upper connecting shaft 205 and the lower support shaft 206, the synchronous driving of the air expansion shaft 301 rotates outwards when the right bearing seat 306 rotates, the other end of the air expansion shaft 301 is separated from the second winding and unwinding groove 210, the third driving motor 509 synchronously rotates and drives the screw 507 to rotate when the air expansion shaft 301 rotates to change rolls, the screw 507 is driven to transversely move by the guide support seat 510 by means of threaded fit with the screw sleeve 512, the position sensor 513 at the top is guaranteed to be over against the top position of the end of the air expansion shaft 301 at the moment, and the position sensor 513 is prevented from separating from the position detection function of the air expansion shaft 301 when the position of the air expansion shaft 301 changes, and bending damage of the subsequent air expansion shaft 301 is avoided.
And then the used film roll is separated along the left bearing seat 302 end, a new film roll sleeve is replaced to the outer surface of the inflatable shaft 301, when the new film roll sleeve is arranged on the outer surface of the inflatable shaft 301 and moves, the third driving motor 509 is started and drives the guide support seat 510 to synchronously move through the screw 507 and the screw sleeve 512, the guide support seat 510 drives the position sensor 513 to move and detect the position of the film roll, so that the accuracy of the moving position of the film roll is ensured, in the moving process, the moving distance of the film roll is matched with the moving distance of the position sensor 513 because the inflatable shaft 301 is in an inclined state, the moving distance of the position sensor 513 is related to the inclined angle of the inflatable shaft 301, and the matching relation can be obtained through multiple experiments and is not repeated.
Simultaneously, as a new film roll moves on the outer surface of the inflatable shaft 301, when the film roll applies an acting force to the inflatable shaft 301, the upper connecting shaft 205 and the lower supporting shaft 206 serve as fulcrums, the top of the other side of the inflatable shaft 301 is in extrusion contact with the bottom of the extrusion plate 518, the end part of the inflatable shaft 301 is extruded and limited by means of the vertical expansion pipe 517 and the extrusion plate 518, and the situation that when the film roll weight is overlarge, a large acting force is applied to the other end of the inflatable shaft 301 to enable the inflatable shaft 301 to incline downwards and cause sliding separation of the film roll and the inflatable shaft 301 is avoided.

Meanwhile, when the air expansion shaft 301 moves upwards at the end of the right bearing seat 306 and reaches the initial height, the position sensor 513 detects that the position of the film roll is restored to the original position, so that the accuracy of the air expansion shaft 301 in installation and reset is further improved, and the situation that the air expansion shaft 301 cannot be reinserted into the second accommodating groove 210 for use after being bent downwards in an inclined manner is avoided.
