Abstract
Various embodiments of the present disclosure provide a strapping tool configured to tension metal strap around a load and, after tensioning, attach overlapping portions of the strap to one another by cutting notches into a seal element positioned around the overlapping portions of the strap and into the overlapping portions of the strap themselves.
Claims19
A strapping tool comprising:
- a support;
- a tensioning assembly mounted to the support and pivotable relative to the support between a strap-tensioning position and a strap-insertion position;
- and
- a trigger assembly comprising:
- a trigger comprising a trigger body and a trigger head extending from the trigger body, wherein the trigger head defines a curved slot, wherein the trigger is mounted to the tensioning assembly via a trigger pivot pin and is pivotable relative to the tensioning assembly and about the trigger pivot pin between a home position and an intermediate position and is pivotable relative to the support and about the tensioning-assembly pivot axis from the intermediate position to an actuated position to move the tensioning assembly from the strap-tensioning position to the strap-insertion position;
- a travel pin mounted to the tensioning assembly and extending through the slot of the trigger head to constrain pivoting of the trigger relative to the tensioning assembly between the home and intermediate positions;
- and
- a trigger gear comprising a trigger-gear head defining a stop surface, a trigger-gear arm extending from the trigger-gear head, and a trigger-gear foot connected to the trigger-gear arm and including trigger-gear teeth, wherein the trigger-gear head is rotatably mounted to the travel pin.
5 more elements
A strapping tool comprising:
- a support;
- a sealing assembly mounted to the support and comprising multiple jaws movable from respective jaw home positions to respective jaw sealing positions;
- a motor comprising a motor output shaft;
- a first freewheel mounted to the motor output shaft, wherein the first freewheel is configured to rotate with the motor output shaft when the motor output shaft rotates in a first rotational direction and not to rotate with the motor output shaft when the motor output shaft rotates in a second rotational direction opposite the first rotational direction;
- a belt pulley mounted to the first freewheel;
- a belt operably connecting the belt pulley to the sealing assembly,
- a second freewheel mounted to the support;
- and
- an anti-rotation gear mounted to the second freewheel and drivingly engaged by the belt, wherein the second freewheel is configured to enable the belt to drive the anti-rotation gear to rotate in the first rotational direction and to prevent the belt from driving the anti-rotation gear to rotate in the second rotational direction.
