Beschreibung
Zusammenfassung:	The invention discloses a tension mechanism of a labeling machine, relates to the technical field of labeling machines, and aims to solve the problems that a friction braking mode of a transmission mechanism of an existing labeling machine easily causes excessive particulate matters and cannot be used for a class 4 clean workshop, and ensures that the tension of a material belt is kept constant. A tension adjusting mechanism, a magnetic powder braking mechanism and a stepping transmission mechanism are arranged in the shell, the stepping transmission mechanism is located on the upper side between the tension adjusting mechanism and the magnetic powder braking mechanism, and a material belt is arranged among the magnetic powder braking mechanism, the tension adjusting mechanism and the stepping transmission mechanism in a transmission fit mode. The magnetic powder braking mechanism can brake a transmission material belt in a non-friction energy consumption mode, torque is transmitted through internal magnetic
