Cotton fiber roll automatic dismounting device

The invention provides a cotton fiber roll automatic dismounting device, and belongs to the technical field of textile detection equipment. The cotton fiber roll automatic dismounting device comprisesa machine frame assembly, a cotton lifting-apart mechanism, a cotton discharging mechanism and a power mechanism, wherein the cotton shifting mechanism is used for shifting cotton fiber roll, the cotton shifting mechanism comprises a tip plate and a first execution element which is arranged on the frame assembly and is used for driving the tip plate to move in the first direction; the cotton discharging mechanism is arranged on the frame assembly and is used for allowing the cotton fiber rolls winding and used for expanding the cotton fiber rolls in second direction; and the power mechanism is used for providing power for the cotton shifting mechanism and the cotton discharging mechanism. According to the device, the cotton shifting mechanism and the cotton discharging mechanism are driven by the power mechanism to shift the cotton fiber rolls and expand the cotton fiber rolls towards the two sides, so that the expanded cotton fiber rolls fall down due to self weight, the cotton fiberrolls can be automatically disassembled, disassembling process is soft, the cotton fiber is small in damage and is not easy to lose, disassembling time is short, the efficiency is high, and convenience is provided for subsequent sample preparation and detection processes; the device relates to an instrument for textile material detection, and the device is suitable for disassembling of a small amount with 2.5-20 grams of cotton fiber rolls.
