Technical Field

[0001] This application is a division of patent application number: 202011007744.8, application date September 23, 2020: Invention name: "A cigarette frame side automatic separation device and separation method".

[0002] The invention relates to the technical field of tobacco manufacturing, in particular to an automatic folding method for a cigarette frame. Background Art

[0003] At present, in the cigarette frame recycling process of the tobacco processing industry, the unused cigarette frame sides are generally lifted and laid flat manually to complete the folding of the cigarette frames. The folded cigarette frames are then stacked with a forklift and stored in a warehouse to reduce the floor space.

[0004] The tobacco frames after leaf beating and re-roasting are recycled and stored. The current folding method is: when the empty tobacco frames are in place, two workers first lift up the side panels on one side of the tobacco frame to disengage the pin on the side panel from the U-shaped slot on the base, and then another worker holds up the upper part of the side panel to lay it down to a horizontal level, and then lifts up the side panel on the other side to disengage the pin on the side panel from the U-shaped slot on the base, and then holds up the upper part of the side panel to lay it down to a horizontal level, completing the folding of the steel tobacco frame.
