Strip tail waste cutting method of cold-rolled sheet processing line uncoiling machine

The invention discloses a strip tail waste cutting method of a cold-rolled sheet processing line uncoiling machine, which belongs to the technical field of metallurgical automation control. The striptail waste cutting method of the cold-rolled sheet processing line uncoiling machine comprises the following steps: a strip tail waste cutting length is set first according to the uncoiling machine, the strip tail waste cutting is divided into a short strip tail processing flow and a long strip tail processing flow, and grating detection is performed on the short strip tail to trigger the strip tail to stop and position to finish cutting; and for the long strip tail, a measuring roller is used for pressing and measuring the coil diameter of the uncoiling machine, the measuring roller is used for calculating the length of the strip tail of the uncoiling machine, and the length of the strip tail is calculated based on the coil diameter of the uncoiling machine, so as to trigger the strip tail to stop and position to
