AI Technical Summary

Technical Problem

During the foil tape deposition process, the crystals of the foil liquid are easily attached to the rollers, resulting in unevenness and defects in the oxide film on the surface of the foil tape, affecting the insulation performance and capacitance of the capacitor.

Method used

A roll for merging is designed, using a combination of spoiler holes, overflow channels and water inlet channels to reduce crystallization adhesion through the spoiler of liquid, combined with the design of grooves and spoiler holes, increase the friction of the foil belt and make up for insufficient support in the groove depressions.

Benefits of technology

It effectively reduces the adhesion of crystals on the rollers, reduces the adverse effects of crystals on the surface of the foil tape, improves the quality of the foil tape, and improves the insulation performance and capacitance of the capacitor.

Abstract

The present application provides a forming roller and a forming tank including the forming roller. The forming roller provided by the present application comprises a main cylinder and end covers arranged at both ends of the main cylinder, a plurality of flow disturbance holes are inwardly penetrated on the surface of the main cylinder, a flow passage is arranged inside the main cylinder, the flow disturbance holes are connected to the flow passage, the main cylinder is also provided with a water inlet channel, one end of the water inlet channel is connected to the flow passage, and the other end of the water inlet channel is connected to an external water inlet pipeline. The provided forming tank comprises a tank body, an upper roller and a lower roller, and the lower roller comprises at least one forming roller. The present application arranges flow disturbance holes on the forming roller, and cooperates with the water inlet of the flow passage and the water inlet channel, so that the flow disturbance holes can spray liquid outward, thereby forming a flow disturbance in the forming liquid at the roller, greatly reducing the area of ​​crystals attached to the roller and preventing falling crystalline objects from adhering to the surface of the roller, so as to reduce the occurrence of defects caused by the crystals imprinting the surface of the foil.
