Description of drawings
Fig. 1 is existing optic fiber polishing machine circuit diagram;
Fig. 2 is the utility model grinder circuit diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
As shown in Figure 2, a kind of optic fiber polishing machine comprises drive motors 1M, break-in motor 2M and the air exhauster 3M that is used to dispel the heat; And starting or stopping control circuit; The main circuit power supply of drive motors 1M is provided with speed regulator, and the speed regulator power end connects working bus bar, and load end connects drive motors 1M.
Said starting or stopping control circuit connects and is located on the working bus bar; Comprise the main branch road of control; Main route start of this control with normal open switch SB2, shut down and be in series with a contact 1A of normally closed switch SB1, a timer and the coil KM of an auxiliary reclay, start shooting with normal open switch SB2 and said auxiliary reclay often to open main contact KM1 parallelly connected.The first auxiliary contact KM2 string of often opening of said auxiliary reclay is located in the main circuit power supply of drive motors, on the power end of said speed regulator.
As other embodiments, timer contact 1A can also be timer-operated probe of contactor.Its reset mode can adopt manually or by timer and set, and concrete mode is relevant with the timer of selection, repeats no more.
Use switch S B2 when pressing start, auxiliary reclay coil KM gets electric, the first auxiliary contact KM2 adhesive, and drive motors 1M running, main contact KM1 adhesive simultaneously guarantees the main branch road conducting of control.When the timer setting-up time arrives, 1A breaks off, auxiliary reclay coil KM dead electricity, and the first auxiliary contact KM2 breaks off, and drive motors 1M shuts down, and main contact KM1 breaks off simultaneously, cuts off the main branch road power supply of control, guarantees that 1A resets.
