地盖供送装置的设计

目的 以天地盖纸盒成型前纸片状物料的供送方式为研究对象，对其在纸盒成型过程中的取料供送进行方案设计，并确定方案中相关的技术参数。方法 设定4种地盖取料供送的可取方案，基于层次分析法（AHP）对影响设计结果的4种决策因素进行权重比较，得出各因素所占权重比；再利用多属性决策法（VIKOR）对4种方案进行分析，从而排定方案的优先顺序，选出最优解。利用SolidWorks进行三维建模，并建立实物模型，对其进行实验验证。结果 根据可接受门槛条件，确定负压吸附旋转式取料为最优取料方式，根据相关技术参数建立的实物模型，经验证与理论要求（120张/min）的最大误差<0.5%，满足使用要求。结论 利用AHP/VIKOR方法为地盖供送装置选取了最优方案，同时建立了适合的负压吸附旋转式取料工艺方法，对成型前地盖供送提供一定的技术借鉴作用。

Design of Bottom Cover Feeding Device

The work aims to design the reclaiming and feeding scheme of paper-like materials in the carton forming process and determine the relevant technical parameters in the scheme, with the feeding mode of paper-like materials before the forming of the top and bottom cover carton. Four feasible schemes for bottom cover reclaiming and feeding were set up. The weight of 4 decision-making factors that affected the design results were compared based on analytic hierarchy process (AHP) to obtain the weight ratio of each factor. Then, the multi-attribute decision-making method (VIKOR) was used to analyze the four schemes so as to prioritize the schemes and select the optimal solution. SolidWorks was used to carry out three-dimensional modeling, and a physical model was established to carry out experimental verification. According to the acceptable threshold conditions, the negative pressure adsorption rotary reclaiming was the optimal reclaiming method. The physical model established according to the relevant technical parameters was verified to have a maximum error <0.5% compared with the theoretically required error of 120 sheets/min, which met the requirements for use. AHP/VIKOR method is used to select the optimal scheme for the bottom cover feeding device, and a suitable method for the negative pressure adsorption rotary reclaiming process is established, which provides certain technical reference for the bottom cover feeding before forming.
