[0016] In this embodiment, the rotation driving device 4 includes a mounting seat 41, a gear driver 42, a first gear 43 and a second gear 44. The mounting seat 41 is located at one end of the back side of the bracket plate 1, and the gear driver 42 is installed on the mounting seat 41. The first gear 43 is connected to the output end of the gear driver 42. The second gear 44 is fixedly installed on the back side of the rotating inner disk 3, and the second gear 44 is meshed with the first gear 43. The upper and lower ends of the second gear 44 are provided with through holes that are compatible with the film rolling rod 7. This design drives the first gear 43 through the gear driver 42, and then transmits power to the second gear 44. Then the rotating inner disk 3 will rotate with the second gear 44, thereby driving the extended rotating inner disk 3 to rotate together to perform the film collection operation.

[0017] In this embodiment, the transverse driving device 5 includes a transverse bracket 51, a transverse cylinder 52, a transverse guide rail 53, a transverse slider 54 and a connecting arm 55. The transverse bracket 51 is installed at the other end of the back of the bracket plate 1, the transverse cylinder 52 is installed on the side of the bracket plate 1, the transverse guide rail 53 is fixed to the side end of the bracket plate 1, the transverse slider 54 is adapted to be installed on the transverse guide rail 53 and connected to the transverse cylinder 52, and one end of the connecting arm 55 is connected to the transverse slider 54. The middle part of the rotating arm 6 is hinged to the other end of the connecting arm 55, and the head and tail ends of the transverse guide rail 53 are provided with in-position sensors 56; this design drives the transverse slider 54 to slide through the transverse cylinder 52, and drives the entire rotating arm 6 and the two film rolling rods 7 on the rotating arm 6 to move transversely through the connecting arm 55, and because the rotating arm 6 and the connecting arm 55 are hinged by bearings, the rotating arm 6 can rotate in the connecting arm 55 under the indirect drive of the gear driver 42, and the transverse load of the transverse cylinder 52 is small, which can effectively save energy consumption.

[0018] In this embodiment, the fixed outer disk 2 is embedded and fixed in the bracket plate 1, and the fixed outer disk 2 and the rotating inner disk 3 are provided with rolling bearings.

[0019] In this embodiment, a film stripping cylindrical block 8 is also fixed on the front of the rotating inner disk 3, and the diameter of the film stripping cylindrical block 8 is less than or equal to the diameter of the rotating inner disk 3. The end of the film rolling rod 7 passes through the second gear 44, the rotating inner disk 3 and the film stripping cylindrical block 8 in sequence, and a diaphragm receiving bin is arranged directly below the film stripping cylindrical block 8; the film stripping cylindrical block 8 is designed for better demolding of the rolled diaphragm, so that when the film rolling rod 7 is recovered and reset, the rolled diaphragm can automatically fall into the diaphragm receiving bin under the blocking of the film stripping cylindrical block 8.

[0020] In this embodiment, a rotation sensor 91 is provided on the front side of the fixed outer disk 2, and a sensing sheet 92 matched with the rotation sensor 91 is provided on the front side of the rotating inner disk 3. This design is used to adjust the position of the rotating inner disk 3 through the sensing sheet 92 each time the film rolling rod 7 is recovered and reset, so that the film rolling rod 7 can restore its initial state on the vertical central axis of the rotating inner disk, which is convenient for the next diaphragm to come in. When the two film rolling rods 7 are extended, the diaphragm is just located between the two film rolling rods 7.

[0021] In the present embodiment, for further automation of the utility model, diaphragm sensors may be provided on the front side of the bracket plate 1 and at the left and right ends of the fixed outer disk 2, respectively. When the diaphragm sensor at the right end senses that the diaphragm is moved into place by the clamping claws, two film rolling rods 7 are extended to place the diaphragm between the two film rolling rods 7. When the diaphragm sensor at the left end does not sense the diaphragm, it proves that the diaphragm has been rolled up, and the two film rolling rods 7 retract into the film stripping cylindrical block 8, and the rolled diaphragm can automatically fall into the diaphragm collecting bin under the blocking of the film stripping cylindrical block 8.

[0022] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
