Research On Clamping Mechanism And Control System Of New Automatic Unloader

As the demand for tobacco in China is increasing year by year,mechanical production of tobacco has become the main way to produce tobacco.However,due to technical problems,there are still some problems in the clamping mechanism of the existing disc unloader.Therefore,this paper studies a new type of automatic disc unloader clamping mechanism and designs the control system of the new type of disc unloader.Through the design of the clamping mechanism of the new disc unloader and the research on the control system,the problems in the process of clamping the box and overturning can be avoided,the working efficiency and quality of the disc unloader can be well improved,the repeated manual labor can be reduced,and the assembly line of the work can be realized,thus having high engineering application value.The specific research contents are as follows:First of all,look up relevant documents,understand the research status of relevant contents,propose the overall working scheme and working principle of the disc unloader,design the overall structure of the disc unloader and design various schemes for the clamping mechanism part of the disc unloader,compare and analyze the various design schemes for the clamping mechanism part to select the better scheme for design,and establish a three-dimensional model of the prototype for the overall scheme structure of the disc unloader.Different clamping forces and contact areas are set for the designed clamping mechanism,statics,dynamics and kinematics analysis are carried out on the clamped full-smoke tray,the relationship among clamping forces,clamping areas and deformation variables is explored according to the analysis results,and the clamping forces and clamping areas which can meet the requirements are selected.The trajectory of the clamping action of the designed clamping mechanism is simulated,and the rationality of the clamping mechanism design is verified by the obtained simulation curve.The overall control system of the automatic disc unloader is designed.The control system is designed according to the proposed control principle.The components of the control system are selected according to the process flow of the disc unloader.The types of sensors are selected and the detection position of the sensors is set.The program is written according to the working requirements and the action requirements of each sensor on the motor and cylinder.Then the control programs of each part are debugged and the linkage program of the overall structure of the disc unloader is written.Can complete various actions of the machine,and can give corresponding signals according to various working conditions.The experiment of the physical prototype verified the stability of the whole movement process of the new disc unloader,analyzed the problems encountered in the experiment process,and put forward the corresponding solutions to finally complete the smooth stability of the whole movement of the prototype.
