Description

Technical Field

[0001] This utility model relates to the technical field of aluminum foil processing equipment, and in particular to an aluminum foil surface coating device. Background Technology

[0002] Surface coating is a key technology in the production of aluminum foil, directly affecting its performance and application results. Traditional coating equipment typically uses simple spraying or roller coating methods. These methods often fail to achieve uniform coating distribution on the aluminum foil surface, leading to inconsistent coating thickness and impacting product quality. Furthermore, traditional coating equipment is prone to paint splattering or dripping during the spraying process, resulting in significant waste and increased production costs. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an aluminum foil surface coating device to solve the problems of uneven coating and paint waste in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] An aluminum foil surface coating apparatus includes an unwinding assembly, a coating box, a drying box, and a rewinding assembly for the aluminum foil to pass through sequentially. The coating box is equipped with a coating tank, and the coating tank contains a coating assembly connected to the coating tank. A collection box is located below the coating assembly, and a recycling assembly is located between the collection box and the coating tank. A uniform distribution assembly is located on the side of the coating tank near the drying box. The uniform distribution assembly includes a uniform distribution roller disposed on the upper wall of the coating tank via a buffer device, and an abutment roller disposed on the bottom wall of the coating tank and disposed opposite to the uniform distribution roller.

[0006] To achieve the above technical solution, aluminum foil enters the coating box via an unwinding assembly. The coating box contains a coating assembly for evenly coating the surface of the aluminum foil. The even distribution assembly includes an even distribution roller and an abutment roller. The even distribution roller is positioned on the upper wall of the coating box via a buffer device, and the abutment roller is positioned on the bottom wall of the coating box. The even distribution roller and the abutment roller work together to ensure uniform coating distribution on the aluminum foil. The coated aluminum foil then enters a drying oven, which provides a heat source to rapidly dry the coating and fix it to the surface of the aluminum foil. The dried aluminum foil is then collected into a roll by a winding assembly.

[0007] In one embodiment of the present invention, the coating assembly includes a spray box, a material storage box disposed in the spray box, a plurality of nozzles disposed at the lower end of the material storage box, and a liquid inlet pipe connecting the material storage box and the paint tank.

[0008] To achieve the above technical solution, the design of the spray box ensures that the nozzle can be accurately aligned with the aluminum foil while preventing paint splattering. The storage box is located inside the spray box and is used to store the paint. The nozzle is responsible for spraying the paint evenly onto the surface of the aluminum foil. The liquid inlet pipe connects the storage box and the paint tank and is responsible for transporting the paint from the paint tank to the storage box. The liquid inlet pipe is usually equipped with a valve to control the flow and flow rate of the paint.

[0009] In one embodiment of the present invention, the lower end of the spray box is provided with a concave material collection plate, and the material collection plate is provided with a plurality of material collection holes.

[0011] In one embodiment of the present invention, the buffer device includes a buffer frame, a connecting rod that is engaged in the buffer frame for mounting the uniform distribution roller, and a buffer spring disposed in the buffer frame and abutting against the connecting rod.

[0012] To achieve the above technical solution, the connecting rod is installed in the buffer frame for mounting the uniform distribution roller. The buffer spring is installed in the buffer frame and abuts against the connecting rod. The function of the buffer spring is to absorb the impact force generated by the uniform distribution roller during rotation, reduce vibration, and ensure the stability of the coating process.

[0013] In one embodiment of the present invention, the upper part of the drying box is provided with a plurality of heating rods, and the lower part of the drying box is provided with a disturbance component.

[0014] To achieve the above technical solution, the heating rod is located at the top of the drying chamber and is responsible for providing the heat source required for drying. The disturbance component is located at the bottom of the drying chamber and its function is to ensure that the coating dries evenly and prevent bubbles or uneven drying of the coating by disturbing the airflow when the aluminum foil passes through the drying chamber.

[0015] In one embodiment of the present invention, the disturbance component includes a disturbance shaft, a plurality of disturbance blades disposed on the disturbance shaft, and a drive component for driving the disturbance shaft to rotate.

[0016] To achieve the above technical solution, the disturbance shaft is responsible for supporting and fixing the disturbance blades, enabling them to perform effective disturbance operations when the aluminum foil passes through the drying box, and the drive assembly is responsible for driving the disturbance shaft to rotate.

[0017] In one embodiment of the present invention, the driving assembly includes a drive motor, a drive gear disposed on the output shaft of the drive motor, and a driven gear disposed on the disturbance shaft and meshing with the drive gear.

[0018] To achieve the above technical solution, the drive gear is mounted on the output shaft of the drive motor and rotates synchronously with the output shaft. When the drive gear rotates, the driven gear rotates accordingly, thereby driving the disturbance shaft to rotate.

[0019] In one embodiment of the present invention, the recycling component includes a recycling pipe connected to the collection box and a recycling pump disposed on the recycling pipe and connected at its output end to the paint box.

[0020] To achieve the above technical solution, the collection box is located at the lower end of the spray box and is used to collect the paint dripping during the spraying process. The recovery pump is installed on the recovery pipe to push the paint to flow in the recovery pipe, ensuring that the paint can be effectively transported from the collection box back to the paint box.

[0021] In one embodiment of the present invention, the unwinding assembly includes an unwinding roller and a guide roller disposed between the unwinding roller and the coating box; the winding assembly includes a winding roller and a reversing roller disposed between the winding roller and the drying box.

[0022] To achieve the above technical solution, the unwinding roller is used to place and unfold the aluminum foil roll; the guide roller ensures that the aluminum foil enters the coating box along a predetermined path and maintains the correct position and orientation during the coating process; the take-up roller is used to collect and wind up the coated aluminum foil; and the reversing roller is designed so that the aluminum foil can come out of the drying box and turn to the take-up roller, ensuring continuous conveying of the aluminum foil.

[0023] As described above, the aluminum foil surface coating device of this utility model has the following beneficial effects: the design of the spray box, storage box and multiple nozzles ensures that the coating can be sprayed evenly onto the surface of the aluminum foil; the combination of the uniform distribution roller and the abutment roller, through the adjustment of the buffer device, ensures that the coating is evenly distributed on the aluminum foil, avoiding the problem of uneven coating thickness; the design of the concave collection plate and collection hole at the lower end of the spray box effectively collects the coating that drips or splashes during the spraying process, reducing waste; the design of the disturbance shaft and disturbance blades generates airflow disturbance, ensuring that the coating dries evenly and preventing the formation of bubbles or uneven drying of the coating.
