[0016] 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.

[0017] Please see Figs. 1-3This utility model provides a technical solution including a preheating oven 1, a leveling box 2, and a material rack 3. An oven door 11 is installed on the front side of the preheating oven 1. Leveling boxes 2 are fixed at the inlet and outlet on both sides of the preheating oven 1. A pair of material trays 31 are installed on the material rack 3. A set of heating rollers 21 are rotatably connected inside the leveling box 2, and a pressure roller 22 is installed on the outer side of each heating roller 21. The pressure roller 22 abuts against the outer surface of the heating roller 21. A mounting bracket 2 is rotatably connected inside the leveling box 2 at a position corresponding to the pressure roller 22 via a mounting shaft 28. 3. The pressure roller 22 is rotatably connected to the end of the mounting frame 23. A telescopic cylinder 24 is installed inside the leveling box 2 at the end of the mounting frame 23 away from the pressure roller 22. The end of the telescopic cylinder 24 is rotatably connected to the end of the mounting frame 23 away from the pressure roller 22. There are five pressure rollers 22, which are arranged in two staggered rows. An infrared thermometer 25 is fixed on the inner side wall of the leveling box 2 at the position corresponding to the heating roller 21. A pressure sensor 27 is installed inside the pressure roller 22. An observation window 26 is opened at the upper end of the leveling box 2, and a transparent glass is fixed inside the observation window 26.

[0018] A buffer frame 4 is fixed on the side of the leveling box 2 near the material rack 3. A fixed guide roller 41 is installed on the lower side of the outer wall of the buffer frame 4. A movable guide roller 42 is installed inside the buffer frame 4. Lifting blocks 43 are installed at both ends of the movable guide roller 42. A lifting groove is opened on the side wall of the buffer frame 4. The lifting block 43 is slidably connected in the lifting groove. A guide rod 44 is fixed in the lifting groove. The guide rod 44 passes through the lifting block 43 and is fixedly connected to the lifting block 43. A buffer spring 45 is fixed between the bottom of the lifting groove and the lifting block 43.

[0019] Working principle: First, connect the entire device to an external power source. Then, pull the diaphragm end out of the material tray 31 and pass it through the buffer frame 4, the front leveling box 2, the preheating oven 1, and the rear leveling box 2. Before preheating, the diaphragm can be heated using the heating roller 21 inside the leveling box 2, while the pressure roller 22 applies pressure to flatten its surface, achieving surface repair. Preheating is then performed, followed by a second leveling process to ensure a highly flat diaphragm surface during subsequent coating. Throughout the process, an infrared thermometer 25 monitors the surface temperature of the heating roller 21, and a pressure sensor is used to... Device 27 detects the applied pressure of pressure roller 22 to ensure that the temperature and pressure are within the preset range. The output end of telescopic cylinder 24 drives the end of mounting frame 23 to rotate around mounting shaft 28. When the two are in contact, the output thrust of telescopic cylinder 24 is increased, which increases the pressure of pressure roller 22 on diaphragm and achieves the purpose of pressure control. Secondly, when the diaphragm is conveyed, since the movable guide roller 42 can move downward under the compression of buffer spring 45, if the diaphragm tension is too high, the movable guide roller 42 can be pulled downward, and conversely, the movable guide roller 42 can be pushed upward, reducing the risk of the diaphragm being pulled and damaged during the roller conveying process.
