近几年来,全国许多单位都在研究解决木工平刨机的安全防护问题,在综合研制成功的几种方案的基础上,国家建委推广了郴县晶体管电子控制双层护罩安全平刨机,保护全面,灵敏度高,不受木料大小,形状、干湿等因素影响,具有多方面的优点。但在实践中感到还存在以下几个问题。 1.摆触头工作不可靠。有时,在它动作后不回复到中间位置,触点继续保持在接通状态,木料刨完后,内罩不关闭。此后,有时还会自动地又动作一次,外罩将所有的刀口外露区盖起来,致使第
In recent years, many units in the country are studying and solving the problems of the safety protection of woodworking planer. On the basis of several schemes that have been successfully developed, the State Construction Commission has promoted the safe control of double-layer safety shield planer of Chenxian transistor electronic control, Protection of comprehensive, high sensitivity, free from the size of wood, shape, wet and dry and other factors, with many advantages. But in practice, there are still the following questions. 1. Touching head work is not reliable. Sometimes, it does not return to the middle position after the action, the contact remains in the on state, after the wood planing, the inner cover does not close. Since then, and sometimes automatically once again, the cover will cover all the exposed areas, resulting in the first
