SED-4MS — Four-Head Cotton Stuffing Machine

Bottles arrive on a height-adjustable conveyor and are stopped by a pneumatic blocker at the cotton-insert station with the bottle mouth aligned to the stuffing head. A stepper-motor-driven cotton feed mechanism pulls strip cotton from a vibratory bowl feeder. Two opposing pinch wheels run at differential speed, tearing the cotton plug to the correct length without a blade. A pneumatic press-down cylinder stuffs the broken plug into the bottle. The released bottle is conveyed to the next station while the next empty bottle takes its place. Photoelectric sensors monitor cotton presence and cut length; touchscreen HMI supports real-time monitoring, parameter setup, and alarm display.
