Designed for high automation, this sealing system features an intelligent cap distribution control unit: when a can body enters the sealing station, a cap is correspondingly dispensed. The machine automatically stops if no can is present to avoid waste, and provides overload or cap shortage alarms to ensure continuous, safe operation. The production speed is infinitely variable via simple button operation, making adjustments and maintenance exceptionally convenient. The structure is simple and compact, ensuring easy part replacement for different can sizes.
