[0021] This utility model provides, for example Figures 1-4 The diaphragm coating machine shown includes a frame 1 with a cloth cylinder 2 mounted on it. During diaphragm coating, the substrate is released from the cloth cylinder 2. A coating roller 3 is mounted on the frame 1 for coating operations, and a take-up roller and other structures are also provided. The coating machine and its working principle are common existing technologies and will not be described in detail here.

[0022] To preheat the substrate and improve coating efficiency, a preheating box 4 is provided on the frame 1, and the preheating box 4 is close to the cloth tube 2. A guide roller 7 is rotatably arranged inside the preheating box 4, and multiple guide rollers 7 can be provided. The substrate released from the cloth tube 2 is wrapped around the guide roller 7, and the guide roller 7 will rotate by friction during the movement of the substrate.

[0023] The preheating box 4 is provided with a conveying pipe 6 for conveying heating gas. A suction pipe 5 is provided at the end of the preheating box 4 away from the conveying pipe 6. The suction pipe 5 is distributed correspondingly to the conveying pipe 6. The conveying pipe 6 and the suction pipe 5 are respectively distributed on both sides of the substrate. The conveying pipe 6 is connected to the heating gas conveying pipeline of the factory, and the suction pipe 5 is connected to the gas suction and treatment pipeline of the factory, and can treat the suctioned impurities.

[0024] Heating gas is ejected from the delivery pipe 6 and acts on the upper and lower surfaces of the substrate simultaneously. At the same time, the suction pipe 5 draws in the used gas, thereby forming a heated airflow on the upper and lower surfaces of the substrate to preheat the substrate and remove impurities from the substrate.

[0025] Considering the compression after winding and the compression of the guide roller 7, some impurities will stubbornly adhere to the substrate, which is difficult to clean by heating airflow alone. To improve cleaning efficiency, a round rod 10 is fixedly connected to the inner wall of the preheating box 4. The round rod 10 is distributed parallel to the guide roller 7, and a swing plate 11 is rotatably connected to the round rod 10. The bottom end of the swing plate 11 is arc-shaped to avoid damaging the substrate. The swing plate 11 cooperates with the guide roller 7 using a first linkage assembly. The first linkage assembly includes a first round block 8, a rotating strip 9, and a second round block 12. The first round block 8 is fixedly connected to the end of the guide roller 7 and is eccentrically positioned. The second round block 12 is fixedly connected to the swing plate 11. One end of the rotating strip 9 is rotatably connected to the first round block 8, and the other end of the rotating strip 9 is rotatably connected to the second round block 12.

[0026] During the movement of the substrate, the guide roller 7 is driven to rotate by friction. When the guide roller 7 rotates, the first linkage component drives the swing plate 11 to swing up and down to beat the substrate, making the impurities loose and easy for the heated airflow to carry away the impurities. When the heated airflow is formed on the upper and lower surfaces of the substrate, it will carry away the loose impurities. Compared with the method of airflow alone, the present invention beats the substrate, which has a better effect on removing impurities.

[0027] In addition, the amplitude of the tapping is appropriate and will not affect the use of the substrate; it can be adjusted according to the specific usage.

[0028] To expand the effective range of the heating gas and improve the preheating effect, a corrugated strip 16 is provided inside the conveying pipe 6, and the corrugated strip 16 is located at the air outlet of the conveying pipe 6, that is, at the end close to the substrate. The swivel plate 11 cooperates with the corrugated strip 16 using a second linkage assembly. The second linkage assembly includes a spring 13, a slide rod 14, and a fixing block 15. The slide rod 14 is slidably mounted on the wall of the conveying pipe 6 and cooperates with the swivel plate 11. The corrugated strip 16 is fixedly connected to the end of the slide rod 14 located inside the conveying pipe 6. The fixing block 15 is fixedly connected to the end of the slide rod 14 close to the corrugated strip 16. The spring 13 is fitted on the outside of the slide rod 14. One end of the spring 13 is fixedly connected to the inner wall of the conveying pipe 6, and the other end of the spring 13 is fixedly connected to the fixing block 15.

[0029] In actual use, when the swivel plate 11 moves downward, it will squeeze the slide rod 14 and retract it into the inside of the conveying pipe 6. When the swivel plate 11 moves upward, the restoring force of the spring 13 will cause the slide rod 14 to return to its original position, thereby causing the corrugated strip 16 to swing back and forth at the air outlet of the conveying pipe 6, agitating the sprayed heating gas, expanding the range of action of the heating gas, and improving the preheating effect.

[0030] This utility model incorporates structures such as a swing plate 11 and a corrugated strip 16. The swing plate 11 swings up and down to beat the substrate, loosening impurities and making it easier for the heating airflow to carry them away. The corrugated strip 16 swings back and forth at the air outlet of the conveying pipe 6 to agitate the heating gas, expand the effective range of the heating gas, and improve the preheating effect.
