technical field

The invention belongs to the technical field of cigarette equipment, and in particular relates to a device and a control method for saving cigarette paper.

Background technique

At present, the production speed of hoods used in the tobacco industry is relatively high, and various downtime phenomena such as "blocking tobacco shreds", "running strips", and "paper breaks" often occur during production. These failures stop every time and waste cigarette paper. Taking the ZJ17 model of the PROTOS series as an example, under normal production conditions, it is normal for a group of equipment to have 5 to 10 "running bars" in a production shift of 8 hours. To slow down to 0, 8 to 11 meters of cigarette paper need to be wasted. This deceleration process has just caused a lot of waste of cigarette paper raw materials. Similarly, manual shutdowns and various small shutdowns that occur during high-speed production can cause varying degrees of waste of cigarette paper.
