Technical Field
[0001] This utility model relates to the field of thin film processing equipment technology, and in particular to a flattening device for processing high transparency and high barrier films. Background Technology
[0002] High-transparency, high-barrier films are widely used in food packaging, pharmaceutical packaging, and electronic device packaging due to their excellent light transmittance and barrier properties. During the processing of high-transparency, high-barrier films, wrinkles and unevenness are prone to occur on the film surface, which not only affects the appearance quality of the film but also reduces its barrier performance and adaptability to subsequent processing. Therefore, a flattening device is needed to treat the film.
[0003] Existing flattening devices only use upper and lower pressure rollers to press and flatten the film during use. However, when the film is directly rolled at room temperature, the internal stress is difficult to release, and springback is likely to occur after flattening. Furthermore, if the heat generated during the rolling process cannot be dissipated in time, it will damage the barrier layer structure of the film, resulting in poor quality of the flattened film. Therefore, it is necessary to design a flattening device for processing high-transparency and high-barrier films. Summary of the Invention

The front end of the second fixed shaft and the front end of the second sealing plate are also fixedly connected to a mounting base, which is fixedly installed on the right support frame by screws.

[0017] Reference Figure 1-7 This utility model provides a flattening device for processing high-transparency and high-barrier films, including a first fixed frame 1, a second fixed frame 2 fixedly connected to the upper end of the first fixed frame 1, a plurality of lower pressure rollers 5 rotatably connected inside the second fixed frame 2, a plurality of upper pressure rollers 4 connected inside the second fixed frame 2 through a lifting mechanism 3, the plurality of upper pressure rollers 4 being located directly above the plurality of lower pressure rollers 5, two left and right distributed support frames 7 fixedly connected to the lower end of the first fixed frame 1, a preheating mechanism 9 installed inside the left support frame 7, and a cooling mechanism 10 installed inside the right support frame 7, and the preheating mechanism 9 and the cooling mechanism 10 being located at the left and right ends of the plurality of lower pressure rollers 5 respectively, and a high-transparency and high-barrier film passing through the upper pressure rollers 4, lower pressure rollers 5, cooling mechanism 10 and preheating mechanism 9.
[0018] During operation, this invention, through the action of the preheating mechanism 9 and the cooling mechanism 10, can not only preheat the film to release the internal stress of the film and prevent springback after flattening, but also cool and shape the flattened film in time to further ensure the flatness effect. At the same time, it avoids the high temperature from damaging the barrier layer structure of the film and ensures the barrier performance of the film. In this way, the quality of the final flattened high transparency and high barrier film is higher.
[0019] Furthermore, the lifting mechanism 3 includes a support frame 301, an electric push rod 302, and a sliding hole 303. The front and rear end faces of the second fixed frame 2 are provided with sliding holes 303. The support frame 301 is slidably connected inside the two sliding holes 303. The support frame 301 passes through the second fixed frame 2 upward and is slidably connected to the second fixed frame 2. Multiple upper pressure rollers 4 are rotatably connected inside the support frame 301. The electric push rod 302 is fixedly connected inside the second fixed frame 2. The output end of the electric push rod 302 is fixedly connected to the support frame 301.
[0020] During operation, the electric telescopic rod can drive the support frame 301 to rise and fall along the sliding hole 303, which in turn drives multiple upper pressure rollers 4 to rise and fall. At this time, the distance between the upper pressure rollers 4 and the lower pressure rollers 5 changes, so that subsequent pressing and flattening operations can be performed on high transparency and high barrier films of different thicknesses.
[0021] Furthermore, the preheating mechanism 9 includes a preheating roller 901, a heating wire 902, a first fixed shaft 903, and a first sealing plate 904. The first fixed shaft 903 is fixedly connected inside the left support frame 7. The preheating roller 901 is rotatably connected to the circumferential surface of the first fixed shaft 903. The heating wire 902 is wound around the circumferential surface of the first fixed shaft 903 and is located inside the preheating roller 901. The first sealing plate 904 for sealing the preheating roller 901 is placed inside the preheating roller 901. The first sealing plate 904 is located at the front end of the first rotating shaft. The front end of the first sealing plate 904 is fixedly connected to a mounting base 8, which is fixedly mounted on the left support frame 7 by screws. The rear end of the first sealing plate 904 is fixedly connected to a first temperature sensor 13, which is located inside the preheating roller 901.
[0022] During operation, the heating wire 902 gradually heats up the interior of the preheating roller 901. When the high-transparency, high-barrier film passes through the preheating roller 901, it is preheated. This preheating releases internal stress, preventing the film from springing back during subsequent flattening operations. The first temperature sensor 13 can sense the internal temperature of the preheating roller 901 in real time, ensuring that the interior of the preheating roller 901 is at a stable and suitable temperature.
[0023] Furthermore, the cooling mechanism 10 includes a cooling roller 1001, a circulating cold water pipe 1002, a second fixed shaft 1003, a water inlet pipe 1004, a water outlet pipe 1005, a first flexible hose 1006, a second flexible hose 1007, a micro pump 1008, a cold water tank 1009, and a second sealing plate 1010. The bottom end of the first fixed frame 1 is fixedly connected to the cold water tank 1009, and the front end of the cold water tank 1009 is fixedly connected to the micro pump 1008. The second fixed shaft 1003 is fixedly connected inside the right support frame 7. The cooling roller 1001 is rotatably connected to the circumferential surface of the second fixed shaft 1003. The circulating cold water pipe 1002 is wound around the circumferential surface of the second fixed shaft 1003. The circulating cold water pipe 1002 is located inside the cooling roller 1001. The second sealing plate 1010 for sealing the cooling roller 1001 is placed inside the cooling roller 1001. The second sealing plate 1010 is located on the second fixed shaft 1007. At the front end of 003, the front end of the second sealing plate 1010 is also fixedly connected to the mounting base 8, and the mounting base 8 is fixedly installed on the right support frame 7 by screws. The inlet and outlet ends of the circulating cold water pipe 1002 are fixedly connected to the inlet pipe 1004 and the outlet pipe 1005, respectively. The inlet pipe 1004 and the outlet pipe 1005 both pass forward through the second sealing plate 1010 and are fixedly connected to the second sealing plate 1010. The front end of the inlet pipe 1004 is fixedly connected to the first hose 1006. The micro pump 1008 is fixedly connected to the first hose 1006, and the first hose 1006 extends backward into the bottom of the cold water tank 1009. The front end of the outlet pipe 1005 is fixedly connected to the second hose 1007, and the second hose 1007 extends backward into the cold water tank 1009 and is fixedly connected to the cold water tank 1009. The inner wall of the cold water tank 1009 is fixedly connected to the second temperature sensor 11.
[0024] During operation, the micro pump 1008 operates, causing cold water inside the cold water tank 1009 to flow along the first hose 1006 and the inlet pipe 1004 into the circulating cold water pipe 1002, and then return to the cold water tank 1009 through the outlet pipe 1005 and the second hose 1007. This cycle keeps the circulating cold water pipe 1002 continuously cool, and the circulating cold water pipe 1002 can transfer coolness to the surface of the cooling roller 1001. The cooling roller 1001 can then cool the flattened high-transparency, high-barrier film. This allows for timely cooling and shaping of the flattened film, further ensuring a smooth finish. The second temperature sensor 11 can monitor the temperature inside the cold water tank 1009 in a timely manner, ensuring that the cold water inside the cold water tank 1009 maintains a suitable temperature. When the temperature inside the cold water tank 1009 is too high, the water inside the cold water tank 1009 can be replaced in time, thereby maintaining the water entering the circulating cold water pipe 1002 at a suitable temperature, thus enabling the cooling roller 1001 to have a good cooling effect.
[0025] Furthermore, a feed inlet is provided on the rear end face of the cold water tank 1009, and a valve and a drain pipe are fixedly connected to the rear end of the cold water tank 1009, with the drain pipe being fixedly connected to the valve.
[0026] During operation, the presence of the feed inlet facilitates the addition of cold water or ice to the cold water tank 1009, while the presence of the drain pipe and valve facilitates the discharge of water that is no longer cold from the cold water tank 1009, thereby replacing the water inside the cold water tank 1009. When circulating the water inside the cold water tank 1009, a sealing plug can be used to block the feed inlet to prevent the cold air inside the cold water tank 1009 from escaping out through the feed inlet and thus prevent the cold water from heating up too quickly.
[0027] Furthermore, a control panel 6 is fixedly connected to the front end of the second mounting bracket 2. The control panel 6 is electrically connected to the first temperature sensor 13, the second temperature sensor 11, the electric push rod 302, the heating wire 902, and the micro pump 1008.
[0028] During operation, the control panel 6 can control the opening and closing of the electric telescopic rod, the heating wire 902 and the micro pump 1008. The temperature values sensed by the first temperature sensor 13 and the second temperature sensor 11 can also be displayed on the screen of the control panel 6, so that the operators can see them more intuitively and replace the cold water or control the heating temperature of the heating wire in a timely manner.
[0029] Furthermore, a fixing plate 12 is fixedly connected inside the first fixing frame 1, and a cooling fan 14 is fixedly installed inside the fixing plate 12. The cooling fan 14 is located at the right end of the upper pressure roller 4 and the lower pressure roller 5.
[0030] During operation, the high-transparency, high-barrier film, after being flattened, first undergoes initial heat dissipation through the cooling fan 14, and then undergoes secondary heat dissipation through the cooling mechanism 10, which can improve the heat dissipation effect. This results in better cooling and shaping of the flattened film.
[0031] Working principle: During use, the produced high-transparency, high-barrier film is first preheated by the preheating mechanism 9 during flattening. This releases the internal stress of the film and prevents it from springing back after flattening. Then, it is flattened between the upper pressure roller 4 and the lower pressure roller 5. Finally, it extends through the cooling mechanism 10. Before passing through the cooling mechanism 10, it is initially cooled by the cooling fan 14, and then cooled a second time by the cooling mechanism 10. This cooling and heat dissipation process ensures that the high-transparency, high-barrier film is cooled and shaped in a timely manner, further guaranteeing the flatness of the high-transparency, high-barrier film. This results in a higher quality high-transparency, high-barrier film.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
