FIELD: packaging industry.
SUBSTANCE: packaging machine mechanism contains the mechanisms for cutting and bonding the packing tape with smoothing, the sliding plate for bonding with smoothing and control mechanism, and also contains the tape supply and return and tensioning device, including the drive roller, the first driven and the second driven rollers, at that the first roller is located after the second tape in the direction of the tape inlet. The first and the second driven rollers disposed eccentrically relatively to each other, the first roller and the drive roller are in constant contact and react with each other to supply and return the belt, the second roller is movable roller and controlled by the control mechanism for moving into the first combined state with the drive roller and moving from the first combined state with the drive roller. The first combined state is the state in which the second roller and the drive roller are in contact and interacted with each other in order to tension the belt. The control mechanism includes the spindle of the machine internal mechanism and the spindle motor, at that the spindle is provided with several cams for controlling the tape cutting mechanism and bonding with smoothing and the sliding plate mechanism for bonding with smoothing, and the tape tension cam to control the second driven roller for moving. Wherein the spindle motor is adapted to drive the machine internal mechanism spindle by means of the speed reduction mechanism, and the tape tensioning cam is configured to control the second driven roller through the rotary system, having the return and the adjustment spring.
EFFECT: simplification, improvement of quality and reliability.
