一种大盘打包机

Abstract

本实用新型提供一种大盘打包机，包括机架，沿打包带的输送方向，机架上依次设置有送带机构、夹持机构和切断热合机构，夹持机构的左右两侧分别设置有左进带轨道和右出带轨道。本实用新型通过上述结构，由张紧调节组件和导带块的配合下，通过张紧调节组件的张紧气缸驱动张紧摆杆的摆动，以带动张紧调节轴的转动，从而能够使得偏心块发生旋转，以调整压带链条与送带机构之间的张紧力，通过张紧摆杆与张紧气缸的配合下，能够起到与杠杆原理相通的省力效果；同时在清理组件的设置下，通过清理组件的清理刷作用下，能够将大盘送带轮表面粘附的打磨下来的打包带材料清理干净，以保证大盘送带轮表面的粗糙度，从而保持大盘送带轮对打包带的输送稳定性。
