Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a rotary winding turntable device for POF film production, including a mounting frame 1, a motor 2 is fixedly connected to one side of the outer wall of the mounting frame 1, a gear 3 is fixedly connected to the output end of the motor 2, a mounting shell 4 is fixedly connected to one side of the inner wall of the mounting frame 1, a fixed shaft 6 is slidably connected inside the mounting shell 4, one end of the fixed shaft 6 is fixedly connected to a rack plate 5, the rack plate 5 is meshed with the gear 3, a tensioning roller 7 is rotatably connected to the outer wall of the fixed shaft 6, a limiting roller 8 is rotatably connected to one side of the inner wall of the mounting frame 1, an electric push rod 9 is rotatably connected to one side of the outer wall of the mounting frame 1, and the electric push rod 9 The output end is fixedly connected with an articulated block 10, a material placement assembly 11 is arranged inside the articulated block 10, the other side of the inner wall of the mounting frame 1 is rotatably connected with a limiting roller 2 13, and one side of the outer wall of the material placement assembly 11 is fixedly connected with an L-shaped ejector plate 12; the material placement assembly 11 includes a rotating rod 1102, the rotating rod 1102 is fixedly connected to the inside of the articulated block 10, the outer wall of the rotating rod 1102 is rotatably connected with a rotating plate 1103, the rotating plate 1103 is rotatably connected with a fixed rod 1101 inside, both ends of the fixed rod 1101 are fixedly connected to the inside of the mounting frame 1, and the L-shaped ejector plate 12 is fixedly connected to the lower surface of the rotating plate 1103;

[0024] Specifically, the POF film is first passed through the tensioning roller 7, the limiting roller 1 8 and the limiting roller 2 13, and finally wound on the winding roller 20; next, by starting the motor 2 15, the belt 17 on the inner wall of the tensioning roller 7 can be driven to rotate; this rotation process realizes the winding effect of the POF film; at the same time, by starting the motor 1 2, the gear 1 3 and the rack plate 1 5 can be driven to mesh and rotate; this action further drives the tensioning roller 7 on the outer wall of the fixed shaft 6 to slide inside the mounting shell 4; this sliding movement enables the tensioning roller 7 to adjust its position as needed, thereby achieving precise adjustment of the tension of the POF film; in addition, in order to further improve the adjustment effect of the tension of the POF film, by starting the electric push rod 9, the rotating rod 1102 inside the hinge block 10 can be pushed to move; this movement process enables the rotating plate 1103 to perform limited rotation on the outer wall of the fixed rod 1101; this rotation movement further enhances the adjustment ability of the tension of the POF film, so that the entire system can more accurately meet production needs.

[0025] Reference Figure 1 , Figure 3 and Figure 4A support frame 14 is fixedly connected to one side of the upper surface of the mounting frame 1, and a motor 2 15 is fixedly connected inside the support frame 14; a rotating shaft 16 is rotatably connected inside the support frame 14, and a belt 17 is transmission-connected between the rotating shaft 16 and the output end of the motor 2 15; a fixed box 18 is fixedly connected to one side of the outer wall of the rotating shaft 16, and a block 19 is slidably connected inside the fixed box 18, and a winding roller 20 is fixedly connected to the outer wall of the block 19; a left-right symmetrical rotating shaft 21 is slidably connected inside the fixed box 18, and a gear 22 is fixedly connected to the outer wall of the rotating shaft 21; a stabilizing block 23 is fixedly connected to the outer wall of the rotating shaft 21, a sliding rod 24 is slidably connected inside the fixed box 18, and a connecting plate 25 is fixedly connected to the upper surface of the sliding rod 24; two sides of the outer wall of the connecting plate 25 are fixedly connected to left-right symmetrical rack plates 26, and the rack plates 26 are meshedly connected with the gear 22, and a spring 27 is sleeved on the outer wall of the sliding rod 24, and one end of the spring 27 is fixedly connected to the lower surface of the connecting plate 25;

[0026] Specifically, with the movement of the rotating plate 1103, the L-shaped ejector plate 12 begins to push the sliding rod 24 to slide inside the fixed box 18; during this process, the movement trajectory of the sliding rod 24 is precise and stable, ensuring the stability and reliability of the entire mechanism; during the movement of the sliding rod 24, its outer wall rack plate 26 meshes and rotates with the gear 22; this design cleverly utilizes the principle of gear transmission, so that the movement of the sliding rod 24 can be converted into the rotational movement of the gear 22; with the movement of the gear 22, the stabilizing block 23 on its outer wall begins to gradually separate from the inside of the block 19; this process requires precise control to ensure that the stabilizing block 23 can smoothly separate from the block 19. When the stabilizing block 23 is completely separated from the block 19, the movement of the rotating plate 1103 further promotes the lifting of the winding roller 20; this action not only allows the winding roller 20 to be easily lifted, but also provides a convenient way for the staff to take it.

[0027] Working principle: when the POF film needs to be rolled up, the POF film is passed through the tensioning roller 7, the limiting roller 18 and the limiting roller 2 13 and wound around the winding roller 20, and the motor 2 15 is started to drive the belt 17 on the inner wall of the tensioning roller 7 to rotate through the motor 2 15 to achieve the effect of rolling up. At this time, by starting the motor 12, the motor 12 drives the gear 13 to mesh and rotate with the rack plate 15, thereby achieving the effect of driving the tensioning roller 7 on the outer wall of the fixed shaft 6 to slide inside the mounting shell 4. Through the movement of the tensioning roller 7, the effect of facilitating the adjustment of the tension of the POF film is achieved. Then, by starting the electric push rod 9, the electric push rod 9 pushes the rotating rod 1102 inside the hinge block 10 to move, thereby achieving the effect of facilitating the rotation of the rotating plate 1103 on the outer wall of the fixed rod 1101 to rotate. Through the movement of the rotating plate 1103, the effect of further adjusting the tension of the POF film is achieved.

[0028] Secondly, when the POF film is rolled up, the movement of the rotating plate 1103 facilitates the L-shaped ejection plate 12 to push the sliding rod 24 to slide in the fixed box 18, thereby pushing the spring 27 to move. The movement of the sliding rod 24 pushes the outer wall rack plate 26 of the connecting plate 25 to engage and rotate with the gear 22. The movement of the gear 22 drives the outer wall stabilizing block 23 of the rotating shaft 21 to disengage from the inside of the card block 19. The movement of the rotating plate 1103 facilitates the lifting of the winding roller 20, thereby achieving the effect of facilitating the staff to take it.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
