One side of the two second fixing plates 20 is fixed with an electric telescopic rod 19 by bolts. One end of the electric telescopic rod 19 passes through the second fixing plate 20 and is fixed with the second clamping plate 18 by bolts. The electric telescopic rod 19 is extended and retracted to move the second clamping plate 18, so that the distance between the first clamping plate 9 and the second clamping plate 18 is adjusted, so that the device can adapt to release film rolls of different sizes. A power component is provided at the bottom of the inner shell 6. At the same time, the inner shell 6 rotates through the power component inside it to drive the connecting shaft to rotate the first clamping plate 9, so that the clamped release film roll rotates to unwind, and the winding roller rotates to rewind, and at the same time the heating wire 14 dries the unfolded part of the release film inside the closed device.

[0024] In the present invention, it should be noted that the power assembly includes a second bevel gear 17, which is fixed to the bottom inner wall of the outer shell 2 by bolts, and a fixing block 15 is fixed to the bottom inner wall of the inner shell 6 by bolts. The internal rotation of the fixing block 15 is connected to a rotating shaft, and one end of the rotating shaft is keyed to the first bevel gear 16, and the first bevel gear 16 is meshed with the second bevel gear 17. The other end of the rotating shaft is keyed to the second sprocket 13, and the other end of the connecting shaft is keyed to the first sprocket 11. A chain 12 is provided between the two first sprockets 11, and the second sprocket 13 is meshed with the chain 12. The inner shell 6 rotates so that the first bevel gear 16 inside it moves with it. Since the second bevel gear 1 7 remains fixed, so that the first bevel gear 16 rotates, and then the rotating shaft drives the second sprocket 13 to rotate. At this time, the first sprocket 11 also rotates through the chain 12. A rubber strip is bonded to the bottom of the cover plate 1, and the rubber strip is in contact with the shell 2. The rubber strip makes the connection between the cover plate 1 and the shell 2 tighter.

The heating wire 14 is fixed to the bottom of the rotating plate 5, and the adjacent first fixed plate 10 and the second fixed plate 20 are maintained at the same horizontal plane.

[0025] Working principle: When the release film needs to be dried, the release film roll and the winding roller are first placed between the two adjacent first clamping plates 9 and the second clamping plates 18 respectively, and the electric telescopic rod 19 is started. The electric telescopic rod 19 extends to clamp the two adjacent first clamping plates 9 and the second clamping plates 18 to clamp the release film roll and the winding roller respectively, and then pull one end of the release film roll around the winding roller, and then start the motor. The motor rotates to rotate the rotating plate 5, and through the cooperation of the clamping block 7 and the clamping slot 8, the inner shell 6 rotates to follow the rotating plate 5. At the same time, the inner shell 6 rotates to make the first bevel gear 16 inside it move with it. Since the second bevel gear 17 remains fixed, the first bevel gear 16 rotates, and then the rotating shaft drives the second sprocket 13 to rotate. At this time, the first sprocket 11 also rotates through the chain 12, and then the connecting shaft drives the first clamping plate 9 to rotate. Therefore, the clamped release film roll rotates to unwind, and the winding roller rotates to rewind. At the same time, the heating wire 14 dries the unwound part of the release film inside the closed device.
