[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a nylon film uniform coating device, comprising: a liquid storage tank 1; a feeding rack 4 and a winding rack 5, the feeding rack 4 being fixedly connected to the outer left side of the liquid storage tank 1, and the winding rack 5 being installed on the outer right side of the liquid storage tank 1; a fixing rod 6, the fixing rod 6 being installed inside the feeding rack 4 and the winding rack 5; a bidirectional lead screw 7 and a handwheel 8, the bidirectional lead screw 7 being rotatably connected to the inside of the two fixing rods 6, and the handwheel 8 being fixedly connected to the bottom of the two bidirectional lead screws 7; two moving blocks 9 and two connecting plates 10, the two moving blocks 9 being threadedly connected to the outer sides of the bidirectional lead screw 7, and the two connecting plates 10 being rotatably connected to the outside of the two moving blocks 9; two connecting blocks 11 and two arc-shaped plates 12, the two connecting blocks 11 being rotatably connected to the top of the multiple connecting plates 10, and the two arc-shaped plates 12 being fixedly connected to the outside of the two connecting blocks 11; and a drying assembly, the drying assembly being used to dry the coated nylon film, with through holes 13 provided on both outer sides of the fixing rod 6. Multiple connecting plates 10 are slidably connected inside two through holes 13. Mounting brackets 2 are fixedly connected to both sides of the outside of the liquid storage tank 1. Guide rollers 3 are rotatably connected inside the two mounting brackets 2. A fixing bracket 25 is fixedly connected to the top of the liquid storage tank 1. A motor 23 is set on the rear side of the outside of the fixing bracket 25. A coating roller 24 is fixedly connected to the output end of the motor 23. The coating roller 24 is rotatably connected inside the fixing bracket 25. A fixing block 22 is fixedly connected to the rear side of the outside of the liquid storage tank 1. The motor 23 is fixedly connected to the upper part of the fixing block 22. A drain port 26 is fixedly connected to the rear side of the outside of the liquid storage tank 1. The drain port 26 facilitates the discharge of liquid inside the liquid storage tank 1. During coating, firstly, the nylon film is installed on the feeding rack 4. One end of the nylon film is pulled out and fixed to the winding rack 5. The nylon film on the feeding rack 4 is released by the rotation of the winding roller. During the nylon film conveying process, the motor 23 of the coating roller 24 is started, which drives the coating roller 24 to rotate, thereby coating the nylon film.

[0035] Specifically, during the feeding process, firstly, the nylon film reel is accurately fitted onto the outside of the fixed rod 6 and the two arc-shaped plates 12. At this time, by rotating the handwheel 8, the rotation of the handwheel 8 drives the internally fixed bidirectional lead screw 7 to rotate as well. The rotation of the bidirectional lead screw 7 causes the two moving blocks 9 connected to its two sides to move relative to each other. The movement of these two moving blocks 9 further drives the four connecting plates 10 connected to it to move relative to each other. When the four connecting plates 10 move relative to each other, they drive the two connecting blocks 11 to move to both sides. As the two connecting blocks 11 move, the two externally fixed... The two arc-shaped plates 12 also move synchronously, allowing them to fit against the inner sides of the nylon film reel, thus fixing the nylon film reel in place. At this point, the loading operation is complete. When disassembly is required, simply rotate the handwheel 8 in the opposite direction to the loading operation. This causes the two arc-shaped plates 12 to separate from the inside of the nylon film reel. With the separation of the two arc-shaped plates 12, the entire disassembly process is successfully completed. Through this operation, the entire loading process does not require cumbersome bolt tightening or loosening operations, simplifying the steps and making the operation more convenient, faster, and less labor-intensive, thereby improving the coating efficiency of the nylon film.

[0036] Reference Figures 4-6 The drying assembly includes a drying chamber 15, which is located at the bottom of the winding rack 5. A fan 16 is installed on the front side of the drying chamber 15. A filter plate 17 is inserted inside the drying chamber 15. A heating wire 18 is installed on the right side inside the drying chamber 15. A conveying pipe 19 is fixedly connected to the rear side of the drying chamber 15. An air outlet 20 is fixedly connected to the top of the conveying pipe 19 to facilitate the discharge of hot air. A horizontal plate 14 is fixedly connected to the bottom of the winding rack 5. The drying chamber 15 is fixedly connected to the top of the horizontal plate 14 to facilitate the fixation of the drying chamber 15. Mounting rods 21 are fixedly connected to both sides of the air outlet 20. The tops of the two mounting rods 21 are fixedly connected to the right side of the liquid storage tank 1 to facilitate the fixation of the air outlet 20.

[0037] Specifically, during the drying process, firstly, the fan 16 is started, drawing in fresh air from outside. After entering the drying chamber 15, the air first passes through the filter plate 17. The filter plate 17 filters the incoming air, removing dust, particulate impurities, and other contaminants that may affect the coating effect. The filtered air continues into the drying chamber 15, where it is heated by heating wires 18 installed inside. The heating wires 18 quickly heat the passing air. The air is rapidly heated to the set working temperature. After the air is fully heated, it is transported through the conveying pipe 19 connected to the end of the drying chamber 15. The conveying pipe 19 delivers the hot air to the inside of the air outlet 20, so that the hot air for drying can be discharged through the air outlet 20. Finally, the hot air discharged through the air outlet 20 directly acts on the surface of the coated nylon film to dry it. This ensures that the coating on the surface of the nylon film can dry quickly at a suitable temperature, avoiding common coating defects such as sagging, blistering, and wrinkles caused by uneven drying, thereby improving the surface quality and smoothness after coating.

[0038] Working principle: During loading, the nylon film reel is first placed over the fixed rod 6 and the two arc-shaped plates 12. Then, the handwheel 8 is turned, which rotates the internally fixed bidirectional screw 7. The rotation of the bidirectional screw 7 causes the two externally threaded moving blocks 9 to move relative to each other. The movement of the two moving blocks 9 causes the four externally rotatably connected connecting plates 10 to move relative to each other. The relative movement of the four connecting plates 10 causes the two top rotatably connected connecting blocks 11 to move to both sides. When the two connecting blocks 11 move, the two externally fixed arc-shaped plates 12 move synchronously, so that the two arc-shaped plates 12 fit against the internal sides of the nylon film reel. During disassembly, the handwheel 8 is turned in the opposite direction to separate the two arc-shaped plates 12 from the inside of the nylon film reel, thus completing the disassembly operation. This facilitates the loading operation of the nylon film reel. During loading, there is no need to tighten or loosen bolts, making the operation simple, time-saving, and labor-saving, thereby improving the coating efficiency of the nylon film.

[0039] During drying, the fan 16 is activated to draw in external air, which is then delivered to the interior of the drying chamber 15. The air entering the drying chamber 15 is first filtered through the filter plate 17, and then heated by the heating wire 18. The heated air is then delivered to the interior of the air outlet 20 through the conveying pipe 19, and finally discharged through the air outlet 20. This process simplifies the drying of the coated nylon film, reducing defects such as sagging, bubbling, and wrinkles, thereby improving the surface quality and smoothness of the coated film.

[0040] 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.
