Sliding-plate type compression claw unit for bundling machine

The utility model relates to a sliding-plate type compression claw unit for a bundling machine, which comprises a rack, a bundling block, a power transmission unit and a sliding-plate type compression claw shifter, wherein the power transmission device comprises a motor, a pinion on the output shaft of the motor, a dynamic gear wheel engaged with the pinion, and a plurality of rollers; the sliding-plate type compression claw shifter comprises a sliding plate and a front upper guide way, a front lower guide way, a rear upper guide way and a rear lower guide way for the sliding plate to horizontally shift on the rack; and the rollers mounted on the flange of the inner hole of the dynamic gear wheel are located in the arc-shaped long waist-shaped hole of the sliding plate. Based on the method of supporting by the outer edge of the dynamic gear wheel of the power transmission device, the utility model enables the sliding-plate type compression claw unit to share the power source with units in other procedures; and the arc-shaped long waist-shaped hole on the sliding plate is driven by the rollers mounted on the flange of the inner hole of the dynamic gear wheel to control the operations of the sliding-plate compression claw, so that the sliding-plate type compression claw unit has the advantages of compact structure and reliable operations, dispenses with electric programmed logic elements for controlling, reduces the manufacturing cost and reduce the failure rate.
