Type of folding machine

A folding machine is a machine that folds large sheets of printed paper into placards according to certain specifications. According to the folding mechanism of the folding machine, the folding machine can be divided into a knife folding machine, a fence folding machine, a grid knife mixed folding machine and a plastic line hot stamping folding machine. In addition, a special folding mechanism is also installed on the web rotary press. 1. Knife folding machine The folding mechanism of the knife folding machine uses a folding knife to press the printed sheet into the middle of a pair of folding rollers that rotate relative to each other, and is then sent out by the folding roller to complete a folding process. When the folding machine is working, the paper sheet is firstly separated by the paper feeding device, and the paper is carried forward by the conveyor belt. After the paper is longitudinally and laterally positioned, the folding knife moves downwards, and the paper is pressed into the relatively rotating folding roller. Between the gaps, the folding rollers send out the first fold. After cutting, a folded signature after punching is sent to the second fold position by the conveyor belt, and then to the third and fourth fold positions to complete the second, third, and fourth fold work. According to the needs of the different folding mechanism and the corresponding receiving device work, you can get fold, fold and format of the different signatures. 2. The folding mechanism of the fence type folding machine fence type folding machine is to use the folding fence and the relative rotating folding roller and the baffle to complete the folding work. The grid folding machine only has two varieties of open and four open, according to the different requirements of folding, changing the number of folding devices of the folding type folding machine and the mutual cooperation of the position of each other, and can fold different signatures of different folding modes. . 3. The folding mechanism of the guillotine-mixing folding machine and the guillotine-mixing folding machine is a folding-folding mechanism and a knife-folding mechanism. Its structural features are generally: one, two fold using the fence type, so the folding speed; three, four folding knife type structure, so folding good quality, stable performance, easy adjustment, easy operation and maintenance. 4. Plastic Line Hot Stamping Folding Machine This machine is equipped with a plastic line hot stamping device before the last folding of a knife or hybrid folding machine. That is, before the last fold in the folding machine, from the inside of the last folding seam of each signature, a special plastic thread is pierced outwards so that the plastic cord forms a foot at both ends and is melted by electric heat. , Adhere to the signature along the creases, and then make the final fold.
