Description

Quick separator for stem and leaf of tobacco with stem Technical Field The utility model belongs to the technical field of tobacco leaf processing, and particularly relates to a rapid separation device for stems and leaves of tobacco leaves with stems. Background In the tobacco leaf harvesting process, 4-6 fully mature leaves at the upper part of the tobacco plant usually adopt a harvesting mode with stems, namely, the connection part of stems and tobacco leaves is reserved for whole-section harvesting. Compared with the traditional single-piece harvesting mode, the harvesting mode with the stems can effectively reduce mechanical damage of the leaves, and the tobacco leaf baking quality is improved through a nutrient reflux mechanism of the stems. The tobacco leaves with stems are required to be separated from tobacco leaves after being baked, so that the tobacco leaves are subjected to further grading treatment, the existing stem and leaf separation mainly relies on manual picking, a large amount of labor is consumed, the working efficiency is low, the large-scale production requirement is difficult to meet, burrs and sharp parts of the stems are extremely easy to scratch the hands of operators in the frequent operation process, and great potential safety hazards exist. Disclosure of utility model In order to solve the technical problems, the utility model designs the quick separation device for the stems and leaves of the tobacco leaves with stems, so as to realize quick stem and leaf separation of the cured tobacco leaves with stems, improve the separation efficiency and reduce the manual loss. The quick stem leaf separating device for the tobacco leaves with stems comprises a supporting platform, wherein the center of the supporting platform is transversely connected with a conical cylinder leftwards, the left end of the conical cylinder is fixedly connected with a separating cylinder, the inner side of the separating cylinder is provided with a plurality of groups of stem leaf separating assemblies in a circumferential array, each stem leaf separating assembly comprises a fixed block fixedly connected to the outer side of the separating cylinder, a movable rod is inserted on each fixed block, one end of each movable rod inserted in the separating cylinder is fixedly connected with a cutter, the right side of the supporting platform is provided with a clamping frame, one side of each clamping frame is provided with a first screw rod, two sections of threads with opposite rotation directions are symmetrically arranged on each first screw rod, one end of each first screw rod penetrates through the clamping frame and is connected with a first servo motor, two symmetrical clamping blocks are connected with each first screw rod in a threaded mode, one side of each clamping frame is fixedly connected with a first optical axis, one side of each clamping block is connected with a second screw rod in a threaded mode, the other side of each clamping frame is sleeved on the second optical axis in a sliding mode, one side of each second screw rod is connected with the right side of the supporting platform through a bracket, and one side of each second screw rod penetrates out of the bracket.
