Loop knotter system for a baler |
摘要 |
A tying mechanism comprising a bill hook, twine holding device for holding strands of twines, a cutting arm adapted for cutting twines between the bill hook and the twine holding device while moving between a rest position and an extended position, a drive adapted to make the bill hook perform at least a first full rotation and a second full rotation and to move the cutting arm from the rest position to the extended position and back during a full operation cycle to form respectively a first and a second consecutive knot wherein the tying mechanism further comprises a tension regulating mechanism able to provide and regulate the tension exerted to the twine holding device during the operation of the tying mechanism. |

1. A tying mechanism comprising
a bill hook twine holding device-for holding strands of twines; a cutting arm adapted for cutting twines between the bill hook and the twine holder whilst moving between a rest position and an extended position; a drive adapted to make the bill hook perform at least a first full rotation and a second full rotation and to move the cutting arm from the rest position to the extended position and back during a full operation cycle to form respectively a first and a second consecutive knot; wherein the tying mechanism further comprises a tension regulating mechanism which is able to provide and regulate tension exerted to the twine holding-device during operation of the tying mechanism; the twine holding device comprises a twine disk having notches for receiving the strands of twine and a twine holder able to press against the twine disk such that the notches is closeable to retain the strands in the notches and wherein the tension regulating mechanism comprises a spring mechanism pressing against the twine holder to urge the twine holder against the twine disk; and wherein the tension regulating mechanism further comprises a tension releasing mechanism comprising at least one shoulder connected to the drive and a plate, the plate moveable at a first end over the shoulder while pushing at a second end against the spring mechanism, as to release the tension exerted by the spring mechanism on the twine holder. |
