The working principle and the beneficial effects of the technical scheme are as follows:
for the winding mechanism 3, an even number of winding rollers are generally provided to perform an alternate winding in consideration of the stress balance.
Referring to fig. 2 and 3, the winding mechanism 3 provided in this embodiment is provided with two rotating winding rollers 34 for alternate winding, that is, one rotating winding roller 34 rotates 180 degrees after winding is completed, and the positions of the two rotating winding rollers 34 are interchanged. When two common alternate winding rollers 34 rotate alternately, the two alternate winding rollers 34 are generally fixedly mounted on the same circular frame, and then the circular frame is driven to rotate by a motor and a transmission device, so that the position exchange of the two alternate winding rollers 34 is realized. However, the interchangeable structure has a certain hidden trouble in rotation. Firstly, during rotation, accurate exchange of positions cannot be ensured, that is, when the previous rotating take-up roll 34 is wound, the position is matched with the pre-finishing mechanism 1 to be in an optimal position (the tension of the intermediate film led out by the pre-finishing mechanism 1 when the intermediate film is wound on the previous rotating take-up roll 34 is optimal). Secondly, during rotation, the circular frame may also deviate to a certain extent in the axial direction, so that the intermediate film cannot be aligned when being wound on the second alternate winding roller 34, and the winding effect is not uniform.
Referring to fig. 3, the rolling frame 33 of the winding mechanism 3 provided in this embodiment is formed by two opposite disk-shaped mounting frames, and the rotating winding roller 34 and the adjusting guide roller 35 are rotatably disposed between the two disk-shaped mounting frames.
The rolling frame 33 is mounted in a position-limited mounting structure. The common installation mode is a central rotating shaft type, that is, a central rotating shaft is fixedly arranged on the central axis of the rolling frame 33, the central rotating shaft is rotatably connected to the bearing frame, and then the central rotating shaft is driven by a motor to rotate, so that the rolling frame 33 is driven to rotate around the axis of the rolling frame. The limiting type mounting structure adopted in this embodiment is to set two symmetrical receiving rollers 32 at the bottom of two ends of the rolling frame 33, respectively, and set a limiting wheel 36 on the end surface of the rolling frame 33, and this limiting type mounting structure can avoid the rolling frame 33 from shifting in the gravity direction and the axial direction when rolling.
In the winding mechanism 3 provided in this embodiment, the power source of rotation is not a central rotating shaft type transmission, but a bottom progressive type transmission is adopted to realize 180-degree rotation of the rolling frame 33. Referring to fig. 3 and 4, two driving ring pieces 51 are respectively fixed at two ends of the rolling frame 33, a circle of progressive short shafts 52 are uniformly distributed and mounted between the two driving ring pieces 51, and progressive tooth surfaces of a progressive wheel 53 are matched with the progressive short shafts 52. That is, the two progressive wheels 53 alternately carry out progressive short shafts 52 one by one, and finally the rolling frame 33 rotates by 180 degrees, and the progressive mode can ensure a rotation angle of 180 degrees, and ensure that the positions of the front and rear two alternate winding rollers 34 are accurately exchanged, thereby ensuring the best tension.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
