Abstract

La présente invention concerne un mécanisme de coupe de papier et un distributeur de papier. Le mécanisme de coupe de papier comprend une crémaillère, un rouleau de coupe et un cadre de dispositif de coupe ; une encoche de dispositif de coupe permettant au cadre de dispositif de coupe d'entrer et de sortir est disposée sur la périphérie du rouleau de coupe, et le rouleau de coupe est pourvu d'un appareil de liaison ; l'appareil de liaison comprend une glissière de liaison disposée sur la crémaillère, un bloc coulissant connecté de manière excentrique au cadre de dispositif de coupe, et une structure de direction ; le bloc coulissant est disposé de manière coulissante dans la glissière de liaison, et la glissière de liaison comprend une glissière de came concentrique avec un centre de rotation du rouleau de coupe, et une glissière en arc ; avec deux révolutions du rouleau de coupe, le bloc coulissant peut effectuer une révolution de mouvement de trajectoire circulaire et une révolution de mouvement de trajectoire de came dans la glissière de liaison en séquence. C'est-à-dire, deux révolutions du rouleau de coupe peuvent entraîner le cadre de dispositif de coupe à effectuer un mouvement de coupe une fois, c'est-à-dire, deux révolutions exécutent une seule coupe de papier. Avec la même longueur de décharge de papier, le diamètre externe du rouleau de coupe peut être plus petit, ce qui permet de réduire la taille globale du distributeur de papier.
