[0002] As the diameter of the film roll gradually increases, the two sides of the film roll will warp up to form flanges. When the two sides of the film roll warp up, it is inconvenient to process the warped film, and a film flange flattening device is needed to flatten the flanged film to ensure the flatness of the film roll. After searching, Chinese Patent Publication No. CN219600375U discloses a film flange flattening device, including a box body, a first motor and a second motor are installed on one side of the box body, and a first guide roller and a second guide roller are respectively arranged on the inner side of the box body corresponding to the positions of the first motor and the second motor, and a film is arranged between the first guide roller and the second guide roller, and the film passes through the box body.

[0023] Embodiment 2:

[0024] like Figures 1 to 3 As shown, a tension detection and adjustment mechanism 3 is fixedly installed on the upper surface of the base 1 and close to the unwinding mechanism 2. The tension detection and adjustment mechanism 3 includes an electric push rod 31 fixedly installed on the upper surface of the base 1, and a pressure sensor 32 is fixedly connected to the top of the electric push rod 31. A U-shaped frame 33 is fixedly connected to the top of the pressure sensor 32. The U-shaped frame 33 is internally rotatably connected to a first guide roller 34. When the film passes over the first guide roller 34, the center of the film's own tension will generate a pressure on the first guide roller 34, which is then detected by the pressure sensor 32. The tension of the film can be known according to the value of the pressure sensor 32. At this time, the electric push rod 31 can be operated according to the tension of the film to drive the first guide roller 34 to rise and fall, change the film tension, and avoid the situation where the film tension is too large or too small and the wrinkles are stretched and relaxed, thereby solving the problem that the existing device cannot detect the film tension and is inconvenient to control the film tension, and wrinkles are easily caused by excessive or too small tension.

[0025] Embodiment 3:

[0026] like Figures 1 to 4 As shown, an L-shaped plate 4 is fixedly installed on one side of the upper surface of the base 1, and a cylinder 5 is fixedly installed at the center position of the upper surface of the L-shaped plate 4.

The film flattening mechanism 7 includes a side plate 71 fixedly installed on the upper surface of the base 1, and a first motor 72 is fixedly installed on one side of the outer surface of the side plate 71. The output shaft of the first motor 72 is fixedly connected to a pressure roller 73, and two second support plates 74 are symmetrically fixedly connected to the lower surface of the top plate 6. A flattening roller 75 that cooperates with the pressure roller 73 is rotatably connected between the two second support plates 74. The rotation of the first motor 72 drives the pressure roller 73 to rotate, and the film is flattened and conveyed with the cooperation of the flattening roller 75, and the operation of the cylinder 5 can drive the flattening roller 75 to rise and fall, so that the distance between the flattening roller 75 and the pressure roller 73 can be changed according to the thickness of the film, thereby improving practicality.

[0027] Embodiment 4:

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, an adjustable guide and limit mechanism 8 is installed on the outer surface of the L-shaped plate 4 and at the positions on both sides of the film flattening mechanism 7. The adjustable guide and limit mechanism 8 includes a bidirectional screw 81 that passes through and is rotatably connected to the outer surface of the L-shaped plate 4. The outer surface of the bidirectional screw 81 is symmetrically threaded with two limit guide plates 82. A guide rod 83 that is fixedly connected to the outer surface of the L-shaped plate 4 and is slidably connected between the two limit guide plates 82. A second motor 84 connected to the bidirectional screw 81 is fixedly installed on one side of the outer surface of the L-shaped plate 4. The rotation of the second motor 84 drives the bidirectional screw 81 to rotate, and the limit guide plates 82 on both sides are driven to move relative to each other through the threads, so that films of different widths can be guided.

[0029] Embodiment 5:

[0030] like Figure 4 As shown, a vertical rod 9 is fixedly installed on the lower surface of the top plate 6 and close to the film flattening mechanism 7, and a first electric heating plate 10 is fixedly connected to the bottom end of the vertical rod 9. A second electric heating plate 11 is fixedly connected to one side of the outer surface of the L-shaped plate 4 and located below the first electric heating plate 10. The first electric heating plate 10 and the second electric heating plate 11 can heat the film to soften it, thereby facilitating flattening, and the cylinder 5 can simultaneously drive the first electric heating plate 10 to move up and down when it is running, so that films of different thicknesses can be heated, further improving practicality, thereby solving the problem that the guide rollers and the heating elements of the existing device are fixed in position and cannot be adjusted according to films of different thicknesses, thereby reducing practicality.

[0031] Embodiment 6:

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, two third support plates 12 are symmetrically fixedly connected to the lower surface of the top plate 6 and one side close to the tension detection and adjustment mechanism 3, and a second guide roller 13 is rotatably connected between the two third support plates 12, and the second guide roller 13 facilitates guiding and conveying the film.

[0033] Working principle: when in use, first start the cylinder 5 according to the thickness of the film. The operation of the cylinder 5 can drive the flattening roller 75 to rise and fall, so that the distance between the flattening roller 75 and the pressure roller 73 can be changed according to the thickness of the film, thereby improving practicality. When the cylinder 5 is running, it can also drive the first electric heating plate 10 to move up and down, so that films of different thicknesses can be heated, further improving practicality, thereby solving the problem that the positions of the guide rollers and the heating elements of the existing device are fixed and cannot be adjusted according to films of different thicknesses, thereby reducing practicality. Then, start the second motor 84 according to the width of the film. The rotation of the second motor 84 drives the bidirectional screw rod 81 to rotate, and the limit guide plates 82 on both sides are driven to move relative to each other through the threads, so that films of different widths can be guided. The film is then moved to the direction, and then the first motor 72 is started. The rotation of the first motor 72 drives the pressure roller 73 to rotate, and the film is flattened and conveyed with the cooperation of the flattening roller 75. When the film passes over the first guide roller 34, the center of the film's own tension will generate a pressure on the first guide roller 34, which is then detected by the pressure sensor 32. According to the value of the pressure sensor 32, the tension of the film can be known. At this time, the electric push rod 31 can be operated according to the tension of the film to drive the first guide roller 34 to rise and fall, so as to change the tension of the film and avoid the situation where the film tension is too large or too small and the wrinkles are stretched and relaxed, thereby solving the problem that the existing device cannot detect the film tension and is inconvenient to control the film tension, and wrinkles are easily caused by excessive or too small tension.
