The invention discloses a buffering comb plate safety device which comprises a trigger mechanism, a switch mechanism and a buffering mechanism, and the comb plate safety device is arranged at the two ends of a comb plate; the trigger mechanism is connected with the comb plate through a connecting shaft, the trigger mechanism is provided with an action beating plate, and the switch mechanism is provided with a safety switch; the action striking plate is opposite to a front-end contact of the safety switch, and when the comb plate is located at an original position, a preset gap S is formed between the action striking plate and the front-end contact of the safety switch; and the buffer mechanism plays a role in buffering after the trigger mechanism is in contact with the switch mechanism. Abnormal upward and backward displacement of the comb plate is converted into single-side backward displacement, so that the function of detecting abnormal displacement in two directions by using one safety switch is achieved, the structure is simple, and maintenance is convenient; and through the action of the buffer mechanism and the limiting mechanism, the risk of damage to the safety switch is reduced.
本发明公开了一种可缓冲的梳齿板安全装置,包括触发机构、开关机构和缓冲机构,所述梳齿板安全装置设置在梳齿板的两端;所述触发机构通过连接轴与梳齿板相连接,所述触发机构具有动作打板,所述开关机构具有安全开关;所述动作打板与安全开关的前端触点相对,当梳齿板位于原始位置时,所述动作打板与安全开关的前端触点间具有预设间隙S;所述缓冲机构在所述触发机构接触开关机构后起缓冲作用。本发明将梳齿板异常的向上、向后位移转化为单侧的向后方向位移,从而实现使用一个安全开关检测两个方向异常位移的功能,结构简单,便于维护;并且通过缓冲机构与限位机构的动作,降低了安全开关损坏的风险。
