目的 为电商快递行业提供一种封装多样化、自动化的纸箱封装机，降低从业人员的劳动强度，提高纸箱封装效率。方法 封箱机主要由底座支撑装置、纸箱对正调整装置、可控连杆手指封装装置、纸箱旋转装置、胶带封装装置及控制系统组成。设计双向丝杠滑台实现不同规格尺寸纸箱的对中、找正。通过控制可控连杆手指封装装置的原动件运动参数，实现不同规格尺寸纸箱的摇盖折合、封装。胶带封装装置由直动式电磁铁、微型真空泵、吸盘等零件组成，与纸箱旋转装置协调配合，共同实现纸箱的十字封装和胶带的自动切断。结果 样机有效工作空间为550 mm×450 mm×300 mm，能够对外形尺寸在(140～550) mm×(140～450) mm×(180～300) mm的纸箱进行封装工作，每个纸箱封装时间为60 s。结论 该纸箱封箱机可完成不同型号纸箱的包装、胶带的十字封装工作，实现了封装多样化与自动化；具有占地空间小、功能柔性可控、造价低的特点，可提高电商快递从业人员的工作效率。

The work aims to provide a diversified and automated carton packaging machine in E-commerce express industry, so as to reduce the labor intensity of employees and improve the efficiency of carton packaging. The carton packaging machine was mainly composed of base support device, adjustment device for cardboard box, finger packaging device with controllable linkage mechanism, carton rotating device, adhesive tape packaging device and control system. Dual screw sliding table was designed to achieve the alignment and centering of cartons of different specifications and dimensions. The flap folding and packaging of cartons of different specifications and dimensions was realized by controlling the motion parameters of driving links of controllable finger packaging device. Adhesive tape packaging device was composed of direct-acting electromagnet, mini vacuum pump, adhesive disc and other parts. Cross packaging of carton and automatic cutting of adhesive tape were carried out with the coordination of adhesive tape packaging device and carton rotating device. Effective working space of the prototype machine was 550 mm×450 mm×300 mm. The prototype machine could package the cartons ranging from 140 mm×140 mm×180 mm to 550 mm×450 mm×300 mm. Each carton packaging time was about 60 s. The carton packaging machine can finish the packaging of cartons of different types and the cross packaging of adhesive tape, which achieves the diversification and automation of packaging. Characterized by small space occupation, flexible and controllable functions and low cost, the packaging machine can improve the working efficiency of E-commerce express employees.
