Abstract

The marking method of the particle packing machine comprises the steps of obtaining the current position of a longitudinal sealing roller when a marking point detection device detects the current marking point of a packing material, subtracting the standard position of the longitudinal sealing roller corresponding to the current marking point from the current position to obtain a position difference value, and calculating the set rotating speed of the longitudinal sealing roller in the next operation period according to the position difference value, so that the length difference value obtained by subtracting the traction length of the longitudinal sealing roller in the next operation period from the traction length of the longitudinal sealing roller in the first operation period under the standard working rotating speed is equal to the position difference value. The method is beneficial to improving the response speed of the alignment, thereby improving the alignment precision. A label alignment system, a particle packing machine and a computer readable storage medium are also provided.
