[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] This utility model provides a diaphragm coating process equipment with a folded-back four-sided coating method, the implementation of which is as follows: Figures 1 to 3 As shown, the system includes an unwinding mechanism 10, a preheating oven 20, a roller coating mechanism 30, a first suspended oven 41, a spraying mechanism 50, a second suspended oven 42, and a winding mechanism 60, arranged sequentially along the diaphragm processing conveying route. The roller coating mechanism 30 includes a first roller coating component 31 and a second roller coating component 32, which are respectively positioned opposite the two surfaces of the diaphragm and are located at different positions along the diaphragm processing path. The first roller coating component 31 and the second roller coating component 32 are respectively used to roller coat the two opposite surfaces of the diaphragm. The spraying mechanism 50 includes a first spraying component 51 and a second spraying component 52, which are respectively positioned opposite the two surfaces of the diaphragm and are located at different positions along the diaphragm processing path. The first spraying component 51 and the second spraying component 52 are respectively used to spray the two opposite surfaces of the diaphragm.

[0029] If only the diaphragm needs to be roller coated, it can be preheated in the preheating oven 20 using the unwinding mechanism 10. After preheating in the preheating oven 20, the diaphragm will be sent to the roller coating mechanism 30. The roller coating mechanism 30 will use the first roller coating component 31 and the second roller coating component 32 to roller coat both opposite surfaces of the diaphragm. After the roller coating is completed, the diaphragm will be sent to the first suspension oven 41 for drying. The dried diaphragm will then pass through the spraying mechanism 50 and the second suspension oven 42. At this time, the spraying mechanism 50 does not need to perform spraying work. Finally, the diaphragm is wound up by the winding mechanism 60.

[0030] If only the diaphragm needs to be sprayed, it can be preheated in the preheating oven 20 using the unwinding mechanism 10. After preheating in the preheating oven 20, the diaphragm will be sent to the roller coating mechanism 30. At this time, the roller coating mechanism 30 does not need to perform roller coating. The diaphragm will be sent directly to the spraying mechanism 50 through the first suspension oven 41. The spraying mechanism 50 will use the first spraying component 51 and the second spraying component 52 to spray both opposite surfaces of the diaphragm. After the spraying is completed, the diaphragm will be sent to the second suspension oven 42 for drying. Finally, the diaphragm will be wound up by the winding mechanism 60.

[0031] If only roller coating and spray coating are required for the diaphragm, the unwinding mechanism 10 can be used to send the diaphragm to the preheating oven 20 for preheating. After preheating in the preheating oven 20, the diaphragm will be sent to the roller coating mechanism 30. The roller coating mechanism 30 will use the first roller coating component 31 and the second roller coating component 32 to roller coat both opposite surfaces of the diaphragm. After the roller coating is completed, the diaphragm will be sent to the first suspension oven 41 for drying. The dried diaphragm will then pass through the spray coating mechanism 50. The spray coating mechanism 50 will use the first spray coating component 51 and the second spray coating component 52 to spray coat both opposite surfaces of the diaphragm. After the spray coating is completed, the diaphragm will be sent to the second suspension oven 42 for drying. Finally, the diaphragm will be wound up by the winding mechanism 60.

[0032] Therefore, this solution allows for double-sided roller coating, double-sided spraying, or even double-sided roller coating and spraying of the diaphragm, thus meeting the usage requirements in various situations.

[0033] It should also be noted that both the first suspended oven 41 and the second suspended oven 42 have upper and lower hulls. The wind speed of the two hulls can be adjusted independently. The hull structure is simulated by fluid dynamics to ensure that the longitudinal wind speed tends to be consistent. The design includes external eight-way air blowers, internal eight-way air blowers, and single slit air blowers, which are flexibly adapted according to the different temperature and air volume curves of each oven section to ensure the uniformity of the wind speed. This allows the diaphragm to float relatively stably in the oven. The adsorption rollers exiting the oven provide traction to ensure the stability of the diaphragm tension in the oven.

[0034] like Figure 2 As shown, this embodiment of the roller coating mechanism 30 also includes a first adsorption roller 33 and a second adsorption roller 34. Along the processing and conveying route of the diaphragm, the first adsorption roller 33, the first roller coating component 31, the second adsorption roller 34, and the second roller coating component 32 are arranged in sequence.

[0035] With this setup, the first adsorption roller 33, the first roller coating component 31, the second adsorption roller 34, and the second roller coating component 32 can be used to achieve smooth and stable conveying of the diaphragm.

[0036] like Figure 1 As shown, this embodiment of the diaphragm coating process equipment also includes a frame platform 70; the unwinding mechanism 10, the preheating oven 20, the roller coating mechanism 30, the first suspended oven 41, and the winding mechanism 60 are all located below the frame platform 70; the spraying mechanism 50 and the second suspended oven 42 are all located above the frame platform 70.

[0037] By adopting this setup, the space above the site can be fully utilized to reduce the space occupied by the diaphragm coating process equipment.

[0038] like Figure 3 As shown, this embodiment of the spraying mechanism 50 also includes a guide roller assembly 53, which is used to guide the diaphragm from the first suspension oven 41 to the second suspension oven 42.

[0039] With this configuration, the diaphragm can be guided from the first suspension oven 41 to the second suspension oven 42.

[0040] like Figure 1 As shown, this embodiment of the diaphragm coating process equipment also includes a correction mechanism 80, which is located on the path of the first suspension oven 41 to send the diaphragm to the spraying mechanism 50.

[0041] With this setup, the correction mechanism 80 can correct the misaligned diaphragm in real time to provide traction and ensure stable diaphragm belt movement.

[0042] like Figure 1 As shown, this embodiment of the diaphragm coating process equipment also includes a traction mechanism 90, which is located on the path of the second suspension oven 42 to send the diaphragm to the winding mechanism 60.

[0043] This setup provides sufficient traction for the diaphragm, ensuring stable, efficient, and smooth diaphragm transport.

[0044] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
