Description

Technical Field

[0001] The invention belongs to the technical field of aluminum foil production, and specifically relates to a baking furnace for producing negative electrode aluminum foil. Background Art

[0002] In the existing aluminum foil etching production line for aluminum electrolytic capacitors, the aluminum foil must be baked after being treated with various liquid chemicals to evaporate or react completely on the surface of the aluminum foil and form a thin oxide film. The baking temperature is usually between 400 and 600 degrees Celsius, and the baking temperature is required to be uniform.

[0003] In the prior art, the foil enters the oven from the front port and is then discharged from the rear port. Although there is an energy-saving drying device that uses a partition to separate the drying box into a preheating zone and a drying zone, in this process, the preheating zone and the drying zone cannot be separated and sealed from the external space, and heat is discharged through the front port and the rear port, resulting in uneven temperature distribution in the oven, which affects the characteristics of the foil and thus affects the quality of the final product. In addition, the hot air discharged from the non-enclosed preheating zone and the drying zone during the drying process causes heat energy loss, which increases production costs, and it is impossible to judge whether the diameter size of the aluminum foil winding meets the requirements during the continuous winding of the aluminum foil.

[0004] Therefore, a furnace for producing negative electrode aluminum foil is needed to solve the technical problems in the prior art that heat discharge leads to uneven temperature in the oven, causing heat energy loss and being unable to judge whether the winding diameter meets the requirements during the continuous winding of the aluminum foil. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a baking furnace for producing negative electrode aluminum foil. During drying, a partition is used to divide the interior of the drying shell into a drying chamber and a preheating chamber. A plurality of groups of extrusion rollers are used to extrude and guide the aluminum foils of different widths and thicknesses, so as to realize the separation and sealing of the drying chamber and the preheating chamber from the external space. The separation and sealing between the drying chamber and the preheating chamber are also realized, which solves the technical problem of uneven temperature in the baking furnace caused by heat discharge in the prior art. The high-temperature airflow during the drying of the aluminum foil is used to preheat the aluminum foil in combination with the airflow pressure difference, so as to realize the preheating and drying of the aluminum foil and improve the drying efficiency of the aluminum foil. The high-temperature airflow during the preheating of the aluminum foil is extracted into the heater through an air pump to shorten the time required for heating the air, which solves the technical problem of heat energy loss in the prior art. The high-pressure airflow can also drive the winding drum to wind the aluminum foil. The diameter size of the aluminum foil winding is determined by the transmission of a specific electrical signal, which solves the technical problem of the prior art that it is impossible to judge whether the diameter size of the winding meets the requirements during the continuous winding of the aluminum foil. The rolled aluminum foil can also be cut after the winding of the aluminum foil is completed.

[0012] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The present application uses a partition to divide the interior of a drying shell into a drying chamber and a preheating chamber, and multiple groups of extrusion rollers are used to extrude and guide the aluminum foil. The aluminum foils of different widths and thicknesses are extruded and guided, so as to realize the separation and sealing of the drying chamber and the preheating chamber from the external space, and also realize the separation and sealing of the drying chamber and the preheating chamber. In combination with the high-pressure airflow pressure difference, the airflow heated in the drying chamber is drawn into the drying chamber to preheat and dry the aluminum foil, thereby improving the drying efficiency of the aluminum foil. The gas in the preheating chamber is drawn into the heater through an air pump to shorten the time required for heating the air.

The high-pressure airflow is heated by the heater and enters the first rotating shell. The first impeller drives the first rotating plate and the first air outlet pipe to rotate. The high-pressure airflow is discharged into the drying chamber through the first air outlet pipe close to one side of the first rotating shell to dry both sides of the aluminum foil. The drying chamber is in a high-pressure state. The air pump extracts air in the preheating shell through the second connecting shell and the second connecting pipe.

The high-pressure airflow in the drying chamber passes through the first connecting shell and the first connecting pipe to enter the second connecting shell. The second impeller drives the second rotating plate and the second air outlet pipe to rotate. The high-pressure airflow is discharged into the preheating chamber through the second air outlet pipe close to one side of the second rotating shell to preheat both sides of the aluminum foil. 4. Use pneumatic telescopic means to drive the support frames on both sides to move, drive the rotating cone to fix the winding drums of different sizes, and the high-pressure airflow can also drive the rotating impeller to rotate. Use the rotating cone to drive the winding drum to rotate and wind the aluminum foil. As the diameter of the wound aluminum foil gradually increases, the aluminum foil rotates on the contact seat through the guide roller, and drives the detection guide rod to move, so that the contact seat touches the contact switch, and it is judged that the diameter of the aluminum foil wound on the winding drum reaches the requirement. At this time, the rotating impeller stops, and the pneumatic telescopic rod is cut off to start, pushing the driving seat and the cutting knife to cut the aluminum foil.
