[0024] The screw 4 is driven to rotate by the forward and reverse motor 5, and the mounting frame 6 is driven by the screw sleeve to move back and forth in the inner cavity of the coating box 1. Then, the squeezing roller 8 installed in the mounting frame 6 through the support spring 9 and the mounting block 7 can move back and forth driven by the moving mounting frame 6 to stretch and squeeze the film, and then the limiting pressure rollers 33 on both sides of the squeezing roller 8 are used to squeeze the film from different directions to remove the internal air and wrinkles, thereby ensuring that the film fits tightly to the surface of the aluminum veneer.

[0025] The conveying frame 2 includes a mounting frame 21, and both sides of the inner cavity of the mounting frame 21 are rotatably connected to a rotating shaft 22 through bearings. A roller 23 is fixed to the outer side of the rotating shaft 22, and a conveyor belt 24 is transmission-connected to the outer side of the roller 23. A driving motor 25 fixedly connected to the end of a group of rotating shafts 22 is fixed to the outer side of the mounting frame 21. The driving motor 25 drives a group of rotating shafts 22 to rotate, and then the rotating shaft 22 drives the conveyor belt 24 to rotate through the roller 23, so as to facilitate the transportation of the aluminum single plate through the coating box 1 for coating treatment.

[0026] The unwinding assembly 3 includes a fixed frame 31, the inner cavity of the fixed frame 31 is rotatably connected to a unwinding roller 32 through a bearing, the outer side of the unwinding roller 32 is wrapped with a film body, and one end of the film body passes through the coating box 1 and extends outward, the inner cavity of the coating box 1 is rotatably connected to a limiting pressure roller 33 through a bearing, the unwinding roller 32 is supported by the fixed frame 31, and then the limiting pressure roller 33 guides the film body so that the film body fits the surface of the aluminum plate transported by the conveyor belt 24.

[0027] It also includes an electric heating box 10 and a blower 11 fixed on the top of the coating box 1. The air inlet of the blower 11 is connected to the electric heating box 10, and the air outlet of the blower 11 is connected to a dispersion box 12 fixed on the top of the inner cavity of the coating box 1 through a conduit. The hot air in the electric heating box 10 is introduced into the dispersion box 12 through the conduit by the blower 11, and the hot air is used to heat the film, so that the film can better adhere to the surface of the aluminum plate.

[0028] The inner cavity of the mounting frame 21 is rotatably connected to a support roller 13 via a bearing. The support roller 13 is located below the squeezing roller 8 and the limiting pressure roller 33. The arrangement of the support roller 13 facilitates the support of the aluminum veneer, thereby preventing the conveyor belt 24 from being unable to stably support the aluminum veneer, causing the conveyor belt 24 to sag under the pressure of the squeezing roller 8, and not having sufficient force to adhere the film to the surface of the aluminum veneer.

[0029] Two groups of through holes are opened inside the installation frame 6, and the inner cavity of the through hole is slidably connected to the limiting rod 14, and both ends of the limiting rod 14 are fixed to the inner cavity of the coating box 1.

Through the setting of the driving belt, it is convenient to utilize the rotating shaft 22 to drive the unwinding roller 32 to rotate synchronously, thereby preventing the film from being unwound quickly due to inertia, resulting in the accumulation of the film and the appearance of wrinkles.

[0031] The front and back sides of the coating box 1 are both threadedly connected to the limiting bolts 17, and the facing ends of the limiting bolts 17 penetrate into the inner cavity of the coating box 1 and fit into the outer side of the mounting frame 21. Through the setting of the limiting bolts 17, it is convenient to fix the mounting frame 21, and the height of the mounting frame 21 can be adjusted at the same time, which is convenient for coating aluminum panels of different thicknesses.

[0032] During specific use, the driving motor 25 is started, and the driving motor 25 drives a group of rotating shafts 22 to rotate, and drives the conveyor belt 24 to rotate through the roller 23 to transport the aluminum veneer, so that the aluminum veneer is transferred to the inside of the coating box 1. At the same time, the rotating shaft 22 drives the unwinding roller 32 to rotate through the driving pulley 15, the driving belt and the driven pulley 16 to synchronously discharge the film. The film body penetrates into the coating box 1 and is located between the limiting pressure roller 33 and the aluminum veneer. With the movement of the conveyor belt 24, the aluminum veneer is transferred, and the limiting roller is driven to rotate to pressurize the film and the aluminum veneer. Then the forward and reverse motor 5 is started, and the forward and reverse motor 5 drives the screw 4 to move the mounting frame 6 back and forth through the screw sleeve. Then the mounting frame 6 drives the squeezing roller 8 to roll back and forth through the supporting spring 9 and the mounting block 7, and the film and the aluminum veneer are squeezed in different directions again to remove wrinkles and air. Then the blower 11 blows the hot air in the electric heating box 10 to the surface of the film through the dispersion box 12, so that the temperature of the film is increased and the adhesion of the film to the surface of the aluminum veneer is improved.
