【摘要】：随着制膜、包装和快递行业的快速发张,胶带分切设备的市场需求逐渐的扩大;但是随着原材料的不断上涨以及劳动力成本的逐渐提高,现有的自动化程度低,功能匮乏的胶带分切设备已经不能满足广阔的市场需求和良好的经济要求。就这种现象,本文对制约分切效率的关键因素进行分析,结果表明纸管不易取下、人工贴标、收废轴快速致满等问题是制约分切效率的关键原因。针对这些问题,本文首先对影响纸管不易取下的原因进行分析研究,通过分析切管轴的振动特性和挠变形规律,对切管轴进行优化设计;采用ANSYS对改进前后的切管轴进行模态分析,验证了改进后的切管轴结构有效的降低了因切管轴振动而造成的其与纸管间的摩擦力增大的问题,从而提高了取管速度。其次,通过对贴标机理分析,三维建模出一种直线贴标机构,然后对其下支撑底板进行数学建模最终确定其合理尺寸,同时对支撑底板的弯曲强度进行校核,验证其是否满足强度要求,最终设计出高效可靠的直线贴标机构。同时,通过对制约收废效率关键因素进行研究,提出采用圆柱凸轮机构来实现废边的横向移动,从而实现拓宽收废轴收废宽度;依据从动件的运动规律建立圆柱凸轮数学模型,通过MATLAB编程求解出凸轮空间啮合曲线,最终建立圆柱凸轮三维模型,并进行运动学仿真验证其从动件是否符合设计要求。最后,对改进前后的切管轴和各部分改进之后墙板的主传动部分,进行跳动测试和振动测试分析,结果显示改进后切管轴的跳动程度明显降低,并且各部分的改进设计并未对墙板的振动造成负面影响。
[Abstract]:With the rapid development of film making, packaging and express delivery, the market demand for tape cutting equipment is gradually expanding, but with the rising raw materials and rising labor costs, the existing automation level is low. Lack of functional tape cutting equipment can no longer meet the broad market demand and good economic requirements. In this paper, the key factors restricting the cutting efficiency are analyzed in this paper. The results show that the key factors that restrict the cutting efficiency are the difficult to take down the paper pipe, the manual labeling and the quick filling of the waste shaft. In order to solve these problems, this paper first analyzes the reasons that affect the paper pipe is not easy to take down, through the analysis of the vibration characteristics of the cutting tube shaft and the law of deflection deformation, the optimization design of the cutting pipe shaft is carried out. The modal analysis of the improved cutting shaft is carried out by ANSYS, which proves that the improved structure can effectively reduce the problem of increasing friction between the pipe and the paper tube caused by the vibration of the cut pipe shaft, and thus improve the speed of pipe extraction. Secondly, through the analysis of the labeling mechanism, a linear labeling mechanism is modeled in 3D, and the reasonable size of the bottom plate is determined by mathematical modeling, and the bending strength of the supporting bottom plate is checked at the same time. Finally, an efficient and reliable linear labeling mechanism is designed to verify whether it meets the requirements of strength. At the same time, through the study of the key factors restricting the efficiency of waste collection, a cylindrical cam mechanism is proposed to realize the lateral movement of the waste edge, so as to widen the waste collection width of the waste shaft, and the mathematical model of the cylindrical cam is established according to the motion law of the follower. The spatial meshing curve of cam is solved by MATLAB programming. Finally, the three-dimensional model of cylindrical cam is established, and the kinematics simulation is carried out to verify whether the follower meets the design requirements. Finally, the runout test and vibration test are carried out on the tube cutting shaft before and after the improvement and the main transmission part of the wall board after the improvement. The results show that the runout degree of the tube cutting shaft is obviously reduced after the improvement. And the improved design of each part does not have a negative impact on the vibration of the wall panel.
