Method of switching between octavo folding and 32mo single join folding

Abstract

The invention discloses a method of switching between octavo folding and 32mo single join folding. The method comprises the steps: 1, paper placing positions of a pair of octavo clamping plates are rotated to 32mo positions through a switch C, meanwhile, a pair of 32mo hooks hook paper stickers at the paper placing positions of the pair of octavo clamping plates, and a pair of 32mo folding knivesextend out at the second 32mo folding positions; 2, a 16mo transmission clutch switch on a 16mo operation control box is pressed down to be turned on, and the 16mo folding device is made to operate along with main transmission of the folding machine; 3, the cutting action of the 16mo folding knife is made to lag through a switch B; 4, the 16mo folding knife is made to move up and down through a switch F, and meanwhile, a newspaper outlet table conveying belt is made to descend to be located at the same horizontal height as the 16mo conveying belt; and 5, a 16mo speed reduction brush descends through a 16mo brush clutch switch. According to the switching method, the octavo folding can be rapidly switched to the 32mo single join folding, convenience and flexibility are achieved, and manual operation is greatly simplified.

Description

technical field [0001] The invention relates to a method for switching from 8-fold to 32-fold. Background technique [0002] The current book folding machines can fold books in 8, 16 and 32 formats. Printing companies need to switch between these formats according to the size of the printed matter. However, due to the complex structure of the existing folding machines, there are often many steps when switching manually, and after switching, it needs to be adjusted slowly, which takes a long time and affects production efficiency. [0003] For the arrangement structure of the rollers of the existing three-cylinder type roller-folding machine, see figure 2 . When not using 32 single-folding pages, the transmission gears of the two folding cylinders 4 and 16 opening and folding devices are disengaged from the main drive and need to be closed manually. To switch back and forth between the 8-fold page and the 32-fold page, the following steps are required: [0004] 1. Open t...
