[0013] The present invention provides a slurry coating device for sintered foil for aluminum electrolytic capacitors. It has the following beneficial effects: 1. The slurry coating device for sintered foil for aluminum electrolytic capacitors is designed with a composite mechanism to place the aluminum foil roll on the surface of the unwinding roller, and then place one side of the aluminum foil roll on the outside of the winding roller for fixing, and the winding roller is driven by a motor to rotate, so as to achieve the function of automatically winding the aluminum foil.

When the winding roller rotates the winding material, it rubs against the coating mechanism, and the aluminum foil is coated by the coating mechanism, thereby reducing manual coating and improving work efficiency. After the coating is completed, the slurry on the surface of the aluminum foil is dried by the processing mechanism to speed up the drying speed of the slurry and avoid leakage in the subsequent winding process, thereby affecting the coating quality. When the winding roller rotates, the equipment is driven to shake, and the buffer mechanism is used for shock absorption and buffering to keep the equipment stable and avoid affecting the coating accuracy, thereby maintaining normal operation.

[0014] Second, the slurry coating device for sintered foil for aluminum electrolytic capacitors is designed with a limiting mechanism, and the aluminum foil roll passes through the bottom of the rotating shaft. The rotating shaft limits the undulating space of the aluminum foil roll to avoid affecting the coating effect of the coating mechanism. Secondly, when the winding roller moves to rewind the aluminum foil roll, it is easy to rub against the rotating shaft, causing the spring rod to contract, thereby achieving the effect of shock absorption and buffering, reducing the friction impact between the material and the components, and improving the stability of the components. At the same time, after the coating mechanism coats the surface of the aluminum foil roll with slurry, it rubs against the rotating shaft close to the processing mechanism side, thereby further smearing the slurry on the surface of the aluminum foil roll, reducing excess slurry and improving the uniform coating quality.

[0015] 3. The slurry coating device for sintered foil for aluminum electrolytic capacitors is designed with a coating mechanism. The coating shell is controlled to rise and fall by the first electric push rod, so as to control the contact height with the material and further improve the laminating effect. The slurry enters the coating shell from the liquid inlet pipe, which reduces the operation of adding slurry manually, improves the working efficiency, and reduces the labor of personnel. The aluminum foil roll is rubbed with the coating roller to achieve the coating operation of the aluminum foil roll. The coating roller is used for coating, which has better coating uniformity and better coating effect. At the same time, the friction rotation is used to control the slurry outflow. In order to control the material flow rate, avoid the discharge of excess slurry and prevent the material surface from being coated too thickly, thereby affecting the drying speed of the slurry, several heaters are arranged and evenly distributed on both sides of the outside of the coating shell. The slurry inside the coating shell is heated by the heater to increase the activity of the slurry and avoid the slurry from cooling and drying up during the coating process, thereby affecting the discharge effect.

The second electric push rod controls the friction shell to fit on the surface of the coating roller, so as to achieve the friction effect on the surface of the component, and clean the clots on the surface of the component by friction, so as to prevent the slurry from drying up on the surface of the coating roller, and avoid multiple dryings leading to excessive coating thickness, thereby affecting the subsequent coating effect. Secondly, the second electric push rod controls the friction shell to stay away from the coating roller, so as to avoid excessive friction and increase wear between components, thereby extending the service life of the components. By opening a housing groove, the contact area is increased by opening the groove, and the friction cleaning effect is improved. At the same time, the chip removal effect is enhanced by grooving, and impurity adsorption is reduced to avoid affecting the subsequent friction effect.

[0017] 5. The slurry coating device for sintered foil for aluminum electrolytic capacitors is designed with a processing mechanism. A hot air flow is generated by a dryer and moves to the circulation pipe, and finally discharged from an external frame, so as to achieve the drying effect of the slurry, promote the slurry to dry and stabilize the coating, so as to facilitate subsequent processing and prevent the slurry from leaking during the winding process, thereby affecting the aluminum foil coating effect. The hot air flow generated by the dryer is circulated, and the rotating mechanism is driven by wind to rotate, so as to rub the inner wall of the circulation pipe, so as to achieve the effect of cleaning dust and prevent excessive accumulation of dust. The grille space on both sides is set by the first orifice plate and the second orifice plate to increase the dust flow space, avoid dust from clogging the holes, and prevent affecting the ventilation effect.

At the same time, the aluminum foil is prevented from shaking during the winding process, thereby affecting the coating effect and thus affecting the subsequent aluminum foil coating quality. When the winding roller 16 rotates the winding material, it rubs against the coating mechanism 2, and the aluminum foil is coated by the coating mechanism 2, thereby reducing manual coating and improving work efficiency. After the coating is completed, the slurry on the surface of the aluminum foil is dried by the processing mechanism 3 to speed up the drying speed of the slurry and avoid leakage in the subsequent winding process, thereby affecting the coating quality. When the winding roller 16 rotates, it drives the equipment to shake, and the buffer mechanism 17 is used for shock absorption and buffering to keep the equipment stable and avoid affecting the coating accuracy, thereby maintaining normal operation.
