Description

Technical Field

[0001] The utility model relates to a material discharging mechanism, in particular to a material discharging mechanism of a sealing machine. Background Technique

[0002] A capacitor mainly comprises an electrolyte and a housing covering the electrolyte. The housing of the existing capacitor is mainly formed by an aluminum shell. During the processing of the capacitor, when the electrolyte is placed into the aluminum shell, in order to prevent the electrolyte from sliding out of the aluminum shell and better protect the electrolyte, it is necessary to perform waist shrinking and sealing operations on both ends of the aluminum shell. The waist shrinking and sealing operations of the capacitor are realized by a capacitor sealing machine. The traditional capacitor sealing machine adopts a vertical structure, that is, the capacitor is in a standing state during the processing. The traditional vertical capacitor sealing machine mainly comprises a main shaft sleeved with one end of the capacitor to make the capacitor stand upright, a sealing mechanism located above the main shaft, and a waist shrinking mechanism located on one side of the capacitor. In order to liberate manual labor, the existing vertical capacitor sealing machine is also equipped with an automatic detection mechanism and a material discharging mechanism. The automatic detection mechanism is used to detect good products and defective products, and the material discharging mechanism clamps and places the good products and defective products after detection in the NO material tank and the OK material tank.
