单张封口条离型纸剥离机理分析和机构设计

Design and Test of Stripping Device for Single Sheet Sealing Strip Release Paper Verification

摘要: 为了解决现包装企业剥离封口条上离型纸这一工序依旧是人工来完成，从而设计一套剥离装置。封口条离型纸为单张离散的，且底纸里嵌入了细铁丝，因此不能采用成卷式标签的剥离方法。故模仿人工剥离，先使用刀具对离型纸边界的粘接力进行破坏，达到初剥离的效果，后利用夹持装置进行完全剥离。由于挠性试件在剥离过程中会使得刚度下降，从而影响夹持效果，故采用comsol的粘附和剥离对离型纸剥离进行仿真，得出最佳的夹持距离为7 mm。后根据设计要求，设计刀具运动轨迹，提出一套凸轮连杆机构来实现刀具运动轨迹，在matlab中绘制凸轮，导入Solidworks进行运动仿真，来验证轨迹。

Abstract: In order to solve the problem that the process of stripping the release paper on the sealing strip of the current packaging enterprise is still manual, a set of stripping device is designed. The release paper of the sealing strip is single and discrete, and the thin iron wire is embedded in the back pa-per, so the stripping method of rolled label cannot be used. Therefore, to simulate manual stripping, first the tool is used to destroy the adhesive force of the release paper boundary to achieve the ef-fect of initial stripping, and then the clamping device is used to completely peel. Because the rigidi-ty of the flexible specimen will decrease during the stripping process, which will affect the clamping effect, the adhesion and stripping of comsol are used to simulate the stripping of the release paper, and the best clamping distance is obtained. Then, according to the design requirements, the paper designs the tool motion path, proposes a set of cam linkage mechanism to realize the tool motion path, draws the cam in matlab, and imports Solidworks for motion simulation to verify the path.
