[0014] 1. This utility model, through the coordinated design of the first coating roller 1 and the second coating roller 2, effectively improves the uniformity of the thermosetting PET protective film during the coating process. Utilizing the high-precision gravure roller structure of the first and second rollers and magnetic levitation tension control technology, precise leveling of the ultra-thin coating is achieved, avoiding the anti-scratch coating defects caused by uneven pressure in traditional equipment, and significantly improving the surface quality of the protective film. Simultaneously, the symmetrical layout design of the drive frame assembly and auxiliary frame assembly, driven by a servo motor and transmission screw, ensures the stable operation of the first moving platform, with the auxiliary support of the second moving platform, guaranteeing the first coating... With the cooperation of the device frame 3, roller 1 and the second coating roller 2 can maintain the set pressure and speed even when running at high speed, thus ensuring the stability and consistency of thermosetting PET protective film in continuous production, further improving product qualification rate and production efficiency. At the same time, with the cooperation of upstream equipment, tension adjustment can be achieved, thereby ensuring that constant tension is maintained during material transmission, avoiding problems such as uneven coating or material deformation caused by tension fluctuations.

Furthermore, the introduction of the electric push rod gives the device a greater advantage in automated control; through connection with the control system, the roller spacing can be adjusted remotely. Process control and real-time monitoring provide strong support for intelligent management of the production process. This enables flexible adjustment of the pressing force between the first coating roller 1 and the second coating roller 2 according to different process requirements, ensuring optimal coating effect under different production scenarios.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1 to 6As shown, a thermosetting PET protective film forming device for facilitating uniform leveling of anti-scratch coating includes a first coating roller 1 and a second coating roller 2. The second coating roller 2 is horizontally mounted above the first coating roller 1, and device frames 3 are vertically connected to both the left and right ends of the first coating roller 1 and the second coating roller 2. A drive frame assembly 4 is horizontally connected to the bottom of the device frame 3 connected to one end of the first coating roller 1, and an auxiliary frame assembly 5 is horizontally connected to the bottom of the device frame 3 connected to the other end of the first coating roller 1. The first coating roller 1 includes a first roller body 101, a first bearing seat 102, a tension sensor 103, and a fixed seat 104. The first bearing seats 102 are mounted on both the left and right ends of the first roller body 101, and the tension sensor 103 is mounted on the side of the first bearing seat 102 away from the first roller body 101. The fixed seat 104 is mounted on the side of the tension sensor 103 away from the first bearing seat 102. The second coating roller 2 includes a second roller body 201 and a second bearing seat. 202, movable seat 203, and docking seat 204. Second bearing seats 202 are installed at both ends of the second roller body 201, and movable seats 203 are located on the side of the second bearing seats 202 away from the second roller body 201. A fixed seat 104 is installed on the top of the movable seat 203. Both the first roller body 101 and the second roller body 201 use high-precision gravure rollers and are equipped with magnetic levitation tension control to ensure the uniformity of the ultra-thin coating. The second bearing seat 202, movable seat 203, and docking seat 204 are interconnected in an integrated structure. The high-precision gravure roller design ensures extremely high flatness of the roller surface during rotation, thereby ensuring a uniform distribution of the coating on the roller surface. The introduction of magnetic levitation tension control technology provides a double guarantee for the uniformity of the coating. By precisely controlling the tension between the rollers, it avoids uneven coating thickness caused by tension fluctuations, thus ensuring high-quality production of thermosetting PET protective film.

[0025] like Figures 1 to 6As shown, the device frame 3 includes a stabilizing frame 301, a support frame 302, an electric push rod 303, and a stabilizing guide rail 304. The support frame 302 is mounted on the top of the stabilizing frame 301, and the electric push rod 303 is vertically mounted on the end of the support frame 302 away from the stabilizing frame 301. The stabilizing guide rail 304 is vertically mounted on the upper end of the side of the stabilizing frame 301 closest to the second coating roller 2. The moving seat 203 and the stabilizing guide rail 304 are connected to each other by a slotted embedded structure. Holes for bolt installation are provided at the top of the stabilizing frame 301 and the bottom of the support frame 302 at four opposite corners. Holes for bolt installation are also provided at the four opposite corners of the fixed seat 104 and the connection point between the fixed seat 104 and the lower end of the stabilizing frame 301. The hole structure for bolt installation, the drive frame assembly 4 includes a first base 401, a servo motor 402, a transmission screw 403, a first moving platform 404, a first guide rail 405, and a first fixed bracket 406. The servo motor 402 is horizontally mounted on one end of the top of the first base 401, and the power output end of the servo motor 402 is horizontally connected to the transmission screw 403 via a coupling. The first moving platform 404 is threaded onto the surface of the transmission screw 403, and the bottom of the first moving platform 404 is connected to the first guide rail 405 via a slotted embedded structure. First fixed brackets 406 are provided at both ends of the first base 401. The auxiliary frame assembly 5 includes a second... The system comprises a base 501, a second fixed bracket 502, a second guide rail 503, and a second movable stage 504. The second base 501 has second fixed brackets 502 at both ends, and a second guide rail 503 is horizontally mounted on the top of the base 501. The second guide rail 503 is connected to the second movable stage 504 via a slotted, embedded structure. Holes for bolt mounting are provided at the top of the first movable stage 404 and the second movable stage 504, and at the four opposite corners of the bottom of the stabilizer 301. Holes for bolt mounting are also provided at the four opposite corners of the bottom of the second fixed bracket 502 and the first fixed bracket 406. The system utilizes a servo motor in the drive frame assembly 4. The machine 402 drives the transmission screw 403 to rotate, which in turn drives the first moving table 404 to make linear motion on the first guide rail 405. This precise linear motion control ensures the stability and accuracy of the first coating roller 1 during the driving process, effectively avoiding coating deviation caused by unstable driving. At the same time, the sliding engagement of the second moving table 504 in the auxiliary frame group 5 on the second guide rail 503 provides stable auxiliary support for the second coating roller 2, enabling the entire coating system to maintain excellent synchronization and coordination when operating at high speed. This dual-drive and auxiliary support design not only improves the stability of the coating process, but also greatly enhances the equipment's adaptability to different production needs.

[0026] In summary, as Figures 1 to 6As shown, the thermosetting PET protective film forming device that facilitates uniform leveling of anti-scratch coating is used by first placing the PET material to be processed between the first coating roller 1 and the second coating roller 2. The height of the support frame 302 is adjusted by the electric push rod 303, so that the moving seat 203 moves precisely along the stable guide rail 304, thereby adjusting the roller spacing between the first coating roller 1 and the second coating roller 2 to accommodate PET materials of different thicknesses.

[0027] Subsequently, the servo motor 402 is started, and its power is transmitted to the transmission screw 403 through the coupling, driving the first moving table 404 to move stably along the first guide rail 405. At the same time, the second moving table 504 is synchronously assisted by sliding support on the second guide rail 503 to ensure that the first coating roller 1 and the second coating roller 2 operate at high speed with the set pressure and speed under the cooperation of the device frame 3.

[0028] The drive frame assembly 4 and the auxiliary frame assembly 5 are firmly fixed to the production platform using the first fixed corner bracket 406 and the second fixed corner bracket 502. The hole structure at the bottom facilitates the secure installation with bolts. This design not only enhances the overall stability of the device, but also ensures that the drive frame assembly 4 and the auxiliary frame assembly 5 will not be displaced due to vibration during long-term operation, thereby ensuring the accuracy and reliability of the operation of the first coating roller 1 and the second coating roller 2.

[0029] During the coating process, the high-precision gravure roller structure of the first roller 101 and the second roller 201 and the magnetic levitation tension control technology play a role in achieving precise leveling of the ultra-thin coating and avoiding defects in the anti-scratch coating caused by uneven pressure. At the same time, the tension sensor 103 monitors and feeds back tension data in real time to ensure that the material maintains constant tension during the transmission process and avoids uneven coating or material deformation caused by tension fluctuations.

[0030] When the pressing force needs to be adjusted, the height of the electric push rod 303 can be remotely controlled through the control system to flexibly adjust the pressing force between the first coating roller 1 and the second coating roller 2 to meet different process requirements. During long-term, high-intensity production operations, this device, thanks to its robust perforated structure design between components, maintains stable performance output, reducing production interruptions and maintenance costs caused by equipment failures, and significantly improving the production efficiency and product quality of thermosetting PET protective films.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
