Take rotary encoder's cross cutting machine

The utility model relates to a take rotary encoder's cross cutting machine, including organism, main shaft, main motor and control system, the main shaft is connected with main motor drive, and the main shaft drives the last mould of cross cutting machine and does the up -and -down motion, and main motor is connected with control system, be provided with the fixed rotary encoder that is provided with on the organism inner wall of main shaft one end, set up the hold -in range between rotary encoder's synchronizing wheel and the main shaft and carry out the transmission, be provided with the signal disc on the other end organism inner wall of main shaft, the fixed inductive switch that is provided with on the organism inner wall of signal disc one side, control system is connected with rotary encoder and inductive switch respectively. Through inductive switch detectable signal dish nose bar, the signal transmission who accomplishes the main shaft a week gives control system, through control system controlled en
