| 目的 为解决现有分级包装设备存在劳动强度大、效率低、易损伤果皮等问题，设计一种基于自动化水果筛选分级包装一体机。方法 将水果通过上料装置输送到果杯中，通过齿轮齿条的配合实现水果的360°旋转，筛选后通过特制的冲模分流装置进行一次分流，进入包装机后利用45DF型凸轮分割器搭配电机带动棘轮实现水果的二次单个分流，利用发泡型塑料网的物理特性，通过凸轮的急回特性来实现单个水果包装自动化。结果 基于机械原理和机械设计，对关键部件进行计算设计和仿真设计，得到传送盘与地面的安装角度为3°，传送盘工作时最大变形量为0.503 69 mm，棘轮工作时最大变形为5.763 9×10−5 mm，最大应变为4.799×10−7，最大应力为9.56×10−4 N，满足使用要求。结论 通过实现分级包装一体机的自动化，减少了劳动力，降低了人工成本，提高了经济效益。 |

| The work aims to design an integrated machine based on automatic fruit screening, grading and packaging, so as to solve the problems of high labor intensity, low efficiency and high probability of damage to the peel found in the existing grading and packaging equipment. The fruit was transported into the cup by the feeding device and rotated for 360° through the cooperation of the gear and rack. After screening, a special punching die diverting device was used for diversion. After the fruit was delivered to the packaging machine, the 45DF cam divider was used together with the motor-driven ratchet to realize the secondary single diversion, and the physical characteristics of the foamed plastic mesh were used to realize the automation of single fruit packaging through the rapid return characteristics of the cam. Based on mechanical principle and mechanical design, the calculation design and simulation design of key components were carried out. The results showed that the installation angle between the conveyor and the ground was 3°, the maximum deformation of the conveyor tray was 0.503 69 mm, the maximum deformation of the ratchet was 5.763 9×10−5 mm, the maximum strain was 4.799×10−7, and the maximum stress was 9.56×10−4 N, which met the use requirements. The realization of automation of the grading and packaging integrated machine reduces labor force, lowers the labor cost and improves the economic benefit. |
