Technical Field

[0001] The utility model relates to the technical field of mandrel processing, in particular to a mandrel feeding and positioning mechanism. Background Technique

[0002] A capacitor core refers to the dielectric part inside a capacitor for storing electric charges. It is usually made of insulating materials and can separate two conductors (electrodes) to form the basic structure of a capacitor. Using metallized paper as the dielectric, it has good stability and a relatively high dielectric constant. During the winding process of the capacitor core, the mandrel feeding link is relatively important. During feeding, it is necessary to achieve the goals of stable feeding process and accurate mandrel positioning, so as to facilitate the winding mechanism to quickly wind the capacitor core and proceed to the next working process.

The overall shape of the entire mechanism is relatively large, and the operation of the mechanism occupies a relatively large space. From the perspective of the overall equipment layout, it occupies a relatively large space. Therefore, the utility model provides a mandrel feeding and positioning mechanism.
