The invention discloses a roller type tobacco leaf loosening and hemp thread removing device. The roller type tobacco leaf loosening and hemp thread removing device comprises brackets and a pluralityof rollers parallelly arranged on the brackets side by side, wherein the rollers can freely rotate on the brackets, a gap is formed between each two adjacent rollers, and nylon sticky hooks are arranged on the surfaces of the rollers; the rollers are connected with a drive mechanism used for driving the rollers. When tobacco leaves fall to the device from a discharge hole, tobacco leaves in smallblocks directly fall to a conveyer belt through the gaps, tobacco leaves in large blocks become loose through extruding, friction and tearing due to mutual rolling of the rollers, meanwhile, the nylonsticky hooks on the rollers suck the impurities including hemp threads, so that the difficulty in eliminating the hemp threads is greatly reduced, and further, the production efficiency is improved.
