Fecha de publicación: 17/07/2018 Fuente: WIPO "tobacco agriculture" The invention provides an automatic loading and unloading device for tobacco leaf curing, which is composed of a frame body, pulley rails, a novel comb tobacco leaf clamp (put forward in another scheme the same day), electric roller shutters, a lifting platform motor, a push-and-pull mechanism, a push-and-pull mechanism motor, a lifting platform, an electrical apparatus control system, a turnoverworking table, and a turnover working table linear motion mechanism. The inner walls of both sides of the frame body are provided from bottom to top with first-layer pulley rails, second-layer pulleyrails, third-layer pulley rails and fourth-layer pulley rails which are bilaterally symmetrical and are used for loading the novel comb tobacco leaf clamp to slide. The first layer, the second layer,and the third layer are tobacco leaf loading layers, and the fourth layer is a transfer layer of the novel comb tobacco leaf clamp. The electrical apparatus control system adopts a single-chip microcomputer or PLC programming to control the lifting platform motor, the push-and-pull mechanism motor, and the turnover working table linear motion mechanism to work. Automatic loading and unloading arecompleted through the cooperative work of the lifting platform, the push-and-pull mechanism, and the turnover working table under the control of the electrical apparatus control system. The automaticloading and unloading device for tobacco leaf curing has the advantages of automation, intensiveness, high efficiency, low work intensity, reasonable structure, superior performance, fastness and reliability, convenient operation, and the like, and is a great improvement of mechanical equipment of modern tobacco agriculture of China.
