[0002] Cast film is a non-stretched, non-directional flat extruded film produced by melt slugging and quenching. The production of cast film mainly includes material selection, extrusion pressure control, temperature control and other steps. It can be produced using a variety of plastic raw materials; cast film folding machine is a device used to process cast film materials, mainly used to fold, stack or wind cast film to meet subsequent production or packaging needs.
[0003] However, when the conventional cast film folding machine is in use, the folding plate structure used for folding is fixed and cannot effectively adapt to cast films of various sizes, which easily makes the folded cast film uneven, and ultimately causes the cast film to fail to achieve the expected folding effect. Utility Model Content

[0017] The utility model discloses a cast film folding machine which is mainly used for conventional cast film folding machines. When in use, the folding plate structure for folding is fixed and cannot effectively adapt to cast films of various sizes, which easily makes the folded cast film uneven, and ultimately leads to the scenario where the cast film cannot achieve the expected folding effect.
[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , a cast film folding machine, comprising an introduction frame 1, an export frame 3 and a mounting frame 2 installed between the introduction frame 1 and the export frame 3, a discharge roll 4 is arranged inside the introduction frame 1, a cast film body 6 is wound around the discharge roll 4, a winding roll 5 is arranged inside the export frame 3, and also comprises: an adjusting mechanism: the adjusting mechanism comprises a fixed seat and a folding plate 9, an adjusting screw 15 is arranged on the fixed seat through a bearing, a threaded sleeve 17 is arranged on the outer wall of the adjusting screw 15, a movable sleeve 16 is sleeved on the outer wall of the threaded sleeve 17, the folding plate 9 is composed of a first side plate 901 and a second side plate 902, the bottom ends of the first side plate 901 and the second side plate 902 are respectively movably connected to the outer walls of one side of the two movable sleeves 16, a motor 8 is arranged on the outer wall of one side of the fixed seat, and the output shaft of the motor 8 is connected to one end of the adjusting screw 15;
[0019] Limiting mechanism: The limiting mechanism is connected to the folding plate 9.
[0020] In this solution, the first side plate 901 and the second side plate 902 can be adjusted separately through the setting adjustment mechanism, and the cast film body 6 of different sizes can be adapted by adjusting the proximity and distance between the first side plate 901 and the second side plate 902, so that the cast film body 6 can be adapted to be wound onto the folding plate 9 after being led out from the unwinding roller 4, thereby ensuring that the cast film body 6 can be flatter during the folding process.
[0021] The folding plate 9 is a triangular structure, and the adjusting mechanism can adjust the two lower corners of the folding plate 9 to quickly adapt the folding plate 9 to the cast film bodies 6 of different sizes.
[0022] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a bottom transfer roller is installed on the inner wall of the introduction frame 1, and two top transfer rollers 7 are provided on the top of the mounting frame 2. One end of the cast film body 6 passes around the bottom transfer roller, the folding plate 9, the top transfer roller 7 and the winding roller 5 respectively.
[0023] Specifically, the cast film body 6 is assisted in being pulled through the folding plate 9 and guided out from the top of the folding plate 9 by being guided by the bottom transfer roller and the top transfer roller 7 .
[0024] Reference Figure 3 and Figure 4 In a preferred embodiment, the limiting mechanism includes a movable buckle arranged on the inner wall of the opposite side of the folding plate 9, a telescopic rod 13 is installed between the two movable buckles, a limiting frame 11 is installed on the inner wall of one side of the mounting frame 2, a transverse groove 12 is opened on the top outer wall of the limiting frame 11, a sleeve is sleeved on the outer wall of the telescopic rod 13, an adjusting rod 10 is installed on the outer wall of one side of the sleeve, and a stopper 14 distributed at equal distances is provided on the bottom outer wall of the adjusting rod 10 away from one end of the sleeve, and the stopper 14 is adapted to the transverse groove 12.
[0025] Specifically, by setting the adjustment rod 10 in cooperation with the stopper 14 installed thereon, a limit can be formed with the transverse groove 12. When the folding plate 9 is adjusted to a suitable flipping angle, the stopper 14 corresponding to the current transverse groove 12 can be inserted into the transverse groove 12. When other suitable angles need to be adjusted, the adjustment rod 10 can be pulled to pull the folding plate 9 to flip, and at the same time, the corresponding stopper 14 can be inserted into the transverse groove 12 to limit the position again, thereby facilitating the pulling of the cast film body 6 of different sizes out of the folding plate 9.
[0026] Working principle: When in use, the cast film body 6 that needs to be folded is placed on the introduction frame 1 together with the wound unwinding roller 4, and then the free end of the cast film body 6 is pulled out, and the cast film body 6 at the free end is passed through the bottom transfer roller and the folding plate 9 in sequence. When the cast film body 6 bypasses the folding plate 9, the first side plate 901 and the second side plate 902 are adjusted to be close and away to adapt to cast film bodies 6 of different sizes. The triangular structure of the folding plate 9 can fold the transported cast film body 6, and finally bypass the top transfer roller 7 and be wound up by the winding roller 5.
[0027] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
