摘要
为提高枕式包装机的包装速度和质量,在枕包机正常封切装置前新增预热封系统,在保证热封效果的前提下,增加复合膜热封时间,提高整机运行速度。通过优化设计往复式封切装置,解决了设备高速运行时震动强、噪音大、复合膜张力变化等问题,将设备机械运行速度上限从280包/min提升到350包/min。研究结果成功应用于某型号往复式高速枕包机设计中并制造了样机,性能测试表明:设备运行噪声和震动明显降低,板式药品枕式包装速度可达300包/min。
In order to improve the packing speed and quality of the pillow packing machine,a preheating sealing system was added in front of the normal sealing and cutting device of the pillow packing machine.This system increased the heat sealing time of composite film and improves the running speed of the whole machine on the premise of ensuring the heat sealing effect.The optimization design of reciprocating sealing and cutting device solved the problems of strong vibration,high noise,the change of composite membrane tension and the like during high-speed operation of the device by reducing the rotary radius of the sealing knife,decreasing the angle of acceleration interval and replacing the unwinding device of magnetic powder braking type with servo control.Besides,the upper limit of the mechanical operation speed of the device increased from 280 packets/min to 350 packets/min.The research content was successfully applied to the design of a reciprocating high-speed pillow packing machine and a prototype was manufactured.The performance test showed that the noise and vibration of the device obviously reduced,and the packing speed surpassed 300 packets/min.
