多刀头瓦楞纸箱打样机设计

目的针对传统型瓦楞纸箱打样机生产效率较低的问题,设计一种新型的多刀头瓦楞纸箱打样机。方法设计压-切一体式刀头,通过控制相应气缸动作实现压痕和切口功能的快速转换;使用气动互锁的固定压爪和移动压爪,配合伺服电机带动的同步带,实现一组横向刀头和多组纵向刀头的组合驱动及定位;采用伺服电机驱动送纸机构实现送纸及纵向切割的进给运动;通过基于PLC的控制系统完成加工参数输入、箱型信息解算及控制指令发送。结果样机经过测试,各部分机构运行正常,精度符合设计要求,控制系统能够完成预定控制任务,加工的纸箱产品外形尺寸误差小于1mm,相较于传统设备所需加工时间减少了25%以上。结论该设备采用并行布置的压-切一体式刀头加工,在保证加工质量的前提下,加工效率得到较大幅度提升。

Design of Multi-cutter Corrugated Box Proofing Machine

The work aims to design a new multi-cutter corrugated box proofing machine, so as to solve the problem of low production efficiency of the traditional corrugated box proofing machine. The design of creasing-cutting integrated cutter head enabled the proofing machine to switch functions between creasing and the cutting by controlling the motions of corresponding air cylinder. The pneumatically interlocking fixed jaw and mobile jaw, combined with the synchronous belt driven by servomotor, could realize the combined driving and positioning of one transverse cutter head and multiple longitudinal cutter heads. The feeding device driven by servomotor achieved paper feeding and feeding motion of longitudinal cutting. PLC-based control system was used to complete processing parameter input, box information calculation and control commands sending. In the test of the prototype, all parts of the mechanism ran normally, the accuracy met the design requirements, the control system could complete the scheduled tasks, and the outline dimension error of the box products was less than 1 mm. The processing time was reduced by more than 25% compared with the traditional device. With the creasing-cutting integrated cutter heads arranged in parallel, the processing efficiency of the proposed equipment is greatly improved on the premise of ensuring the processing quality.
