[0024] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0025] To address the problems existing in the background art, this application proposes the following technical solution: a film production winding unit, including a base frame 1, which supports all the parts in this embodiment. A long shaft 20 is rotatably connected inside the base frame 1. A pair of cross-shaped swing frames 2 located at both ends of the long shaft 20 are fixedly connected to the long shaft 20. Several horizontally placed idler rollers 19 arranged in a circular array around the central axis of the long shaft 20 are rotatably connected to the two cross-shaped swing frames 2. A rubber cylinder 4 is sleeved on the outside of the idler rollers 19. The idler rollers 19 drive the rubber cylinder 4 to rotate. The rubber cylinder 4 is used to wind up the film 3. A pair of square electric telescopic rods 5 are fixedly connected to the top surface inside the base frame 1. The telescopic ends of the two square electric telescopic rods 5 are rotatably connected to horizontally placed pressure rollers 8. The pressure rollers 8 are located above the rubber cylinder 4 to be loaded and downward. The moving contact film 3 and pressure roller 8 continue to move downwards so that the other side of film 3 contacts the glue cylinder 4 to be loaded. A pair of first electric telescopic rods 6 are fixedly connected to the inner top surface of the base frame 1. The telescopic ends of the two first electric telescopic rods 6 are fixedly connected to horizontally placed heating wires 7. The heating wires 7 are located between the pressure roller 8 and the working glue cylinder 4 and are close to the pressure roller 8. The heating wires 7 are used to cut film 3. A micro generator can be installed at the telescopic end of the first electric telescopic rods 6. The heating wires 7 are heated by the power of the micro generator. Film 3 is wound on the working glue cylinder 4. One section of film 3 is located between the pressure roller 8 and the glue cylinder 4 to be loaded. The working glue cylinder 4 is the glue cylinder 4 that is currently winding film 3. The glue cylinder 4 to be loaded is the next glue cylinder 4 that needs to be wound film 3.

[0026] In this embodiment, each swing end of the two cross swing frames 2 is fixedly connected to a lower clamping block 16. A lower semi-circular hole 23 is provided on the upper surface of the lower clamping block 16. An upper clamping block 17 is provided above the lower clamping block 16. An upper semi-circular hole 24 is provided on the lower surface of the upper clamping block 17. A rotating circular hole is formed between the upper semi-circular hole 24 and the lower semi-circular hole 23. A second electric telescopic rod 15 for driving the upper clamping block 17 to move radially along the long axis 20 is fixedly connected to the outside of the lower clamping block 16. The telescopic end of the second electric telescopic rod 15 is fixedly connected to the upper clamping block 17. The cylinder of the second electric telescopic rod 15 is fixedly connected to the swing end of the cross swing frame 2. Both ends of the roller 19 are rotatably connected in the rotating circular hole. The upper clamping block 17 and the lower clamping block 16 are the same size. After the upper clamping block 17 and the lower clamping block 16 are attached, the upper semi-circular hole 24 and the lower semi-circular hole 23 form a rotating circular hole.

[0027] In this embodiment, the roller 19 extends outward from both ends within the rotating circular hole, and a second gear 13 is fixedly connected to the extension section of one end. A first motor 14 is fixedly connected to the swing end of the cross swing frame 2. A first gear 12 is fixedly connected to the output shaft of the first motor 14. The first gear 12 meshes with the second gear 13. When the first motor 14 starts to run, the first gear 12 fixed to the output shaft of the first motor 14 rotates. The rotation of the first gear 12 drives the rotation of the second gear 13, which in turn drives the roller 19 to rotate. A third electric telescopic rod 18 is embedded near the edge of the roller 19. The telescopic end of the third electric telescopic rod 18 extends outward through the rubber tube 4. The third electric telescopic rod 18 is used to ensure the relative position of the rubber tube 4 and the roller 19. The function of the third electric telescopic rod 18 is similar to that of a positioning pin.

[0028] In this embodiment, a horizontally placed second roller 11 is rotatably connected inside the base frame 1. The second roller 11 guides the film 3. The second roller 11 is close to the discharge end of the film 3 and away from the working glue cylinder 4. The second roller 11 is higher than the glue cylinder 4 to be loaded and lower than the working glue cylinder 4. A horizontally placed first roller 9 is rotatably connected inside the base frame 1. The first roller 9 guides the film 3. The first roller 9 is away from the second roller 11 and close to the discharge end of the film 3. The first roller 9 is lower than the second roller 11. A fourth electric telescopic rod 22 is provided below the second roller 11. The telescopic end of the fourth electric telescopic rod 22 is horizontally pointed to the discharge end of the film 3. The telescopic end of the fourth electric telescopic rod 22 is rotatably connected to a horizontally placed push roller 10. The push roller 10 is lower than the second roller 11 and higher than the first roller 9. When the fourth electric telescopic rod 22 extends, the push roller 10 increases the distance of the film 3 conveying stage, providing time for changing the glue cylinder 4. The film 3 comes out from the discharge end, passes under the first roller 9, above the push roller 10, above the second roller 11, between the pressure roller 8 and the glue cylinder 4 to be loaded, and is finally wound up by the working glue cylinder 4. The film 3 is a continuous planar strip.

[0029] In this embodiment, the long shaft 20 extends outward through the base frame 1, and a second motor 21 is fixedly connected to one side of the base frame 1. The output shaft of the second motor 21 is fixedly connected to the long shaft 20. The second motor 21 is used to drive the glue tube 4 that is currently winding the film 3 to rotate to the position of the previous working glue tube 4.

[0030] To ensure that those skilled in the art can fully understand the technical solution, the usage method of this embodiment is as follows: When a preset amount of film 3 is wound onto the working glue cylinder 4, the square electric telescopic rod 5 extends, driving the pressure roller 8 to move downwards. After the pressure roller 8 touches the film 3, it continues to move downwards. When the pressure roller 8 approaches the glue cylinder 4 to be loaded, the telescopic end of the fourth electric telescopic rod 22 extends, driving the push roller 10 to move towards the film 3 discharge end. The film 3 contacted by the pressure roller 8 contacts the glue cylinder 4 to be loaded, and the first motor 14 at the working glue cylinder 4 stops operating. The telescopic extension of the first electric telescopic rod 6... The first electric telescopic rod 6 extends, causing the heating wire 7 to move downwards and cut the film 3. After the film 3 is cut, the first electric telescopic rod 6 retracts, causing the heating wire 7 to move away from the film 3. After the film 3 is cut, the first motor 14 at the working rubber tube 4 starts, and stops rotating after winding up the excess film 3. The second electric telescopic rod 15 extends, causing the upper clamping block 17 to move away from the lower clamping block 16. The telescopic end of the third electric telescopic rod 18 retracts into the idler roller 19. The worker uses tools to remove the idler roller 19, takes out the wound rubber tube 4, and replaces it with a new rubber tube 4, which is then fitted onto the outside of the idler roller 19. The third electric telescopic rod 18 extends through the pre-drilled hole on the rubber cylinder 4. Workers use tools to install the replaced idler roller 19 between the upper clamping block 17 and the lower clamping block 16. The second electric telescopic rod 15 retracts, causing the upper clamping block 17 and the lower clamping block 16 to clamp the idler roller 19. The second gear 13 on the idler roller 19 needs to mesh with the corresponding first gear 12. When the film 3 is cut, the square electric telescopic rod 5 retracts, moving the pressure roller 8 away from the film 3. At this time, the first motor 14 at the rubber cylinder 4 to be installed starts, and through the meshing of the first gear 12 and the second gear 13... Power is transmitted to the idler roller 19, and the third electric telescopic rod 18 inside the idler roller 19 drives the roller 4 to rotate and wind up the film 3. At this time, the second motor 21 starts and rotates the roller 4 that is winding up the film 3 to the position of the previous working roller 4. During the process of the roller 4 rotating to the position of the previous working roller 4, the fourth electric telescopic rod 22 slowly retracts to avoid causing the film 3 to suddenly loosen. At the same time, the speed of the first motor 14 increases to keep the film 3 in a taut state that does not loosen or break. This completes the roller replacement without stopping the machine in the blow molding production process, and the above process is repeated.
