DETAILED DESCRIPTION

[0018] 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.

[0019] Example: Figs. 1-3 As shown, a double-sided roll-to-roll coating machine includes a coating body 18. A feeding rack 1 is provided on one side of the coating body 18. A feeding roller 2 is rotatably connected to the outer wall of the feeding rack 1. A conveying product 3 is provided on the outer wall of the feeding roller 2. A drive roller 4, which is in contact with the outer wall of the conveying product 3, is rotatably connected to the outer wall of the coating body 18. A conveying roller 5, located on one side of the drive roller 4, is rotatably connected to the outer wall of the coating body 18. An oil tank body 6 is provided on the inner wall of the coating body 18. A connecting roller 7 is rotatably connected to the inner wall of the oil tank body 6. An exhaust hood 8 is provided on the inner wall of the coating body 18. The coating machine body 18 has a main drying chamber 9 inside, and a connecting power roller 10 is rotatably connected to the inner wall of the main drying chamber 9. An active roller 11 located on one side of the connecting power roller 10 is rotatably connected to the inner wall of the coating machine body 18. The coating machine body 18 also has a secondary drying chamber 12 inside, a cooling chamber 13 inside, and a cooling fan 14 on the inner wall of the cooling chamber 13. An adjusting roller 15 is rotatably connected to the bottom of the coating machine body 18, and a storage rack 16 is provided on the other side of the coating machine body 18. A receiving roller 17 is rotatably connected to the inner wall of the storage rack 16.

[0020] Furthermore, the oil tank body 6 is set on the transport track of the conveying product 3, and the conveying product 3 is completely immersed inside the oil tank body 6 for transport. This facilitates the effect of double-sided immersion transport of the product by setting the oil tank body 6 on the transport track of the conveying product 3.

[0021] Furthermore, the main drying chamber 9 is positioned above the exhaust hood 8. There are two sets of exhaust hoods 8, and the positions of the two sets of exhaust hoods 8 are symmetrical about the central axis of the conveying product 3. This facilitates the effect of drying the product after the main drying chamber 9 is positioned above the exhaust hood 8.

[0022] Furthermore, the auxiliary drying box 12 is located on one side of the main drying box 9. The outer wall contours of both the main drying box 9 and the auxiliary drying box 12 are U-shaped, which facilitates the multi-stage drying and conveying of products by placing the auxiliary drying box 12 on one side of the main drying box 9.

[0023] Furthermore, the cooling fan 14 is arranged in a straight line on the inner wall of the cooling chamber 13, which facilitates multi-directional cooling of the product after drying.

[0024] Furthermore, a conveying trough is provided at the connection between the bottom of the main drying chamber 9 and the exhaust hood 8. The feeding roller 2, drive roller 4, conveying roller 5, connecting power roller 10, active roller 11 and adjusting roller 15 are all powered to convey the product. This facilitates the convenient conveying of the initially air-dried product through the conveying trough at the connection between the bottom of the main drying chamber 9 and the exhaust hood 8.

[0025] Working Principle: When using this double-sided roll-to-roll coating machine, during the PCB conveying process, in order to improve the effect of complete immersion on both sides of the product, the conveying roller 5 causes the product to be conveyed through the oil tank body 6. When the product is output from the oil tank body 6, it will be conveyed in the middle of the two sets of exhaust hoods 8, so that the product will be exhausted by the exhaust. At the same time, under the action of the connecting power roller 10, the pre-dried product is conveyed to the main drying box 9 for double-sided drying. After the initial double-sided drying, the product is conveyed to the auxiliary drying box 12 for secondary drying by the rotation of the drive roller 11. After the secondary drying, the product passes through the cooling chamber 13 to achieve convenient cooling on both sides. Finally, the product is conveniently wound up by the rotation of the take-up roller 17. The viscosity of the ink forms a protective layer. After the surface drying in the main oven, the real-time coating thickness of the product can be measured.

[0026] This is the working principle of this double-sided roll-to-roll coating machine.
