Item is connect with the gear of driving motor output end.
The rotary drum folding device further includes folding rotating mechanism corresponding with every group of mandrel 4, the folding rotating mechanism
It can make two mandrels of outside first opposed, inwardly directed overturning in every group of mandrel when wheel hub rotates and retract, then keep two mandrels of inside opposite
Inwardly overturns and retract.
When this rotary drum folding device is run, for driving motor by chain-driving rotary drum around middle shaft rotation, cutter will
Junction cut-out of the Gauze between different mandrel groups, folds rotating mechanism and drives one group of core when rotating to certain position
Blade in axis on two mandrels of outside is rolled on the both sides of the Gauze to centre, later two blade inward against overturning
Reverse flip resets.After the blade on two mandrels resets on the outside, the folding rotating mechanism drives inside two in this group of mandrel
Blade on mandrel is inward against overturning, by the Gauze doubling after once folding, when Gauze comes drawing mechanism position
Two blade reverse flips described in when setting reset.
So, convex by using the multigroup mandrel cooperation for being uniformly arranged four one group of mandrels on wheel hub circumferencial direction
Mechanism is taken turns successively to be folded inward with two operations of doubling to complete the folding to the Gauze after cutting, to realization pair
The auto-folder of Gauze is saved manually, and structure is relatively simple, and folding rate is efficient soon.
