Description

碎纸机防卡纸保护装置
技术领域
本发明涉及碎纸机技术领域，更具体地，涉及碎纸机的保护装置技术领域，特别是指一种碎纸机防卡纸保护装置。
背景技术
目前常用的市售碎纸机的一种较科学的保护装置，是利用大量碎纸在进入切割刀片后，以大量要碎纸张的反作用力迫使工作电机因扭力不够而转速减慢时，其电机轴芯尾端的编码转盘侦测到有减速后，通过碎纸机控制电路的限定而使电机停止工作，以保护电机和传动的齿轮。
因为以上的保护装置是在电机减速时或根本转不动后才使电机停止工作，以保护电机和传动的齿轮，而此时电机已处于超负荷运行中，多次此类操作后无疑会造电机的失效，或造成传动齿轮打坏而机器完全不能工作。
市售碎纸机的另一种较科学的保护装置，是利用大量碎纸在进入切割刀片前，以量大的要碎纸张推动入纸触动杆，使触动杆尾端的光学感应组件侦测到编码转盘的形位量变化，在变位量超过机器限定时通过控制电路使电机停止工作，以保护电机和传动的齿轮。
此保护装置因为是利用光学组件侦测到编码转盘的变位量，而碎纸机工作时会产生较多灰尘，灰尘会影响光学感应组件侦测时的精度，即检测纸厚时的精度，从而会出现偏差，造成判断失误，从而导致电机超负荷运行，多次此类操作后无疑会造电机的失效，或造成传动齿轮打坏而机器完全不能工作。
