Background

In the prior art, in the engraving process of an electronic engraving machine, an engraving head leans against a plate making roller to engrave, and a certain pressure is kept between the engraving head and the plate making roller. If the pressure is constant, the precision of the plate making roller is very high, the rotating speed of the plate making roller in the engraving process is constant, and the electric engraving needle vibrates and engraves at the inherent frequency, and ideally, the plate making roller does not engrave the transverse grains. In the actual engraving process, the vibration frequency of the electric engraving needle is constant, the printing roller is driven by the main transmission shaft to rotate, the main transmission shaft is driven by the motor and the transmission wheel, and the motor and the transmission wheel are connected by the belt. The tightness of the belt thus directly determines the speed at which the plate-making roller rotates, and this is one factor that affects the engraving of transverse striations. The other factor influencing the transverse striation is the head-leaning inertia of the engraving head, and the reduction of the rotation inertia of the engraving head relative to the plate making roller can also reduce the occurrence of the transverse striation.
