The present invention relates to driving and braking method and device of marker, and adopts brushless DC motor for driving and one-way bearing for reverse braking in marker. The driving and braking device includes one frame, one base board, one motor on the base board, one sync driving belt wheel connected to the motor shaft and one character wheel shaft driven with the motor shaft, as well as one sync driven belt wheel driven with the sync driving belt wheel, one sync driving belt, one one-way bearing, character wheels and one electric controller. The motor is one brushless DC motor with commutation sensor, and the sync driven belt wheel is fixed through connector to the character wheel shaft. The driving and braking device may be installed onto one automatic packing machine for high speed printing, and has stable and reliable braking performance.
Description
technical field [0001] The invention relates to an ink wheel coding machine, in particular to a driving braking method and a driving braking device for the ink wheel coding machine installed on an automatic packaging machine. Background technique [0002] Most of the coding machines on the existing food and pharmaceutical automatic packaging machines do not have high-speed printing functions, and the general working speed is within 300 times / min. They use colorless printing to identify the production date and shelf life for manufacturers and consumers. bring some difficulties. [0003] The existing coding machines are mainly driven by mechanical and stepping motors. The disadvantages of mechanical coding machines are that the mechanical parts wear fast and the noise is large, and it cannot achieve the effect of high-speed operation; while the coding machine driven by stepping motors Due to the high rigidity of the stepping motor, it is difficult to achieve printing synchron...
