技术介绍
现有的固版机在进行固版的过程中都是靠机械机构进行控制的,即靠大量的凸轮与行程开关的接触达到控制的目的。但由于凸轮和行程开关间是相互摩擦接触的,因而,在使用的过程中由于磨损而出现误差,造成固版状态的不稳定,且设备一工作即开始固版,开始时温度低,版头固版不牢固。而且,机械接触出现故障的概率很高。专利技术目的本技术的目的是提供一种无机械接触、固版状态稳定、固版头尾效果一致的固版机控制器。技术解决方案这种固版机控制器,包括电源电路,接在电源电路上的开关电路,与开关电路并联的延时电路,与延时电路并联的稳速调速电路;接在电源输入端上的温度控制电路;开关电路包括串联后接在电源输出端上的发光二极管LED和电阻R1,串联后与发光二极管LED和电阻R1并联的受光二极管D1、电阻R2和电阻R3,基极接在电阻R2和电阻R3间的三极管V1,接在三极管V1集电极上的继电器J1;温调控电路包括接在电源电路输入端的继电器J1长开触点J1-2,与常开触点J1-2串联的电位器RP3,与电位器RP3串联的电容C6,与长开触点J1-2、电位器RP3和电容C6并联的双向可控硅VS,接在电位器RP3和电容C6间与双向可控硅VS控制端连接的双向阀值二极管VT。由于有开关电路和温度控制电路,当遮光片离开发光二极管LED时,二极管D1受光导通,三极管V1导通,继电器J1得电工作,温度控制电路的继电器J1长开触点J1-2闭合,使双向阀值二极管VT控制可控硅处于间断导通状态,固版灯工作于预热状态,当延迟电路延迟完毕进行固版工作时,固版温度已经升高、版头版 ...
