Understand the "heart" knotter of a baler from four aspects

    The knotter is known as the "heart" of the baler, and its performance directly determines the quality of the baler's operation. Currently, D-type heavy-duty knotters are mainly used in the market.

    In 1858, Appleby invented the rope bundling machine, and 20 years later, manufacturer Dilin applied Appleby's bundling method to the production of bundling machines.

    In 1921, Krass Company in Germany invented one of the main components of a knotter, the knotting mouth.

Main components of the knotter:

The knotter frame is composed of components such as the worm gear, worm, worm shaft bevel gear, gear disc, knotter shaft bevel gear, rope release rod, knotter mouth, rope gripper, etc. that drive the rope gripper.

Working principle:

1. Before starting the operation, place the needle in the starting position and thread the rope through the guide, needle hole, and other links according to the specified threading route, firmly clamping it inside the rope gripper.

2. After the machine starts working, the needle swings upwards from its starting position, guiding the other end of the rope towards the gap in the knotter disc, and then the rope pulling plate pulls the rope sent by the needle towards the billhook. As the disc rotates, the rope is clamped between the disc and the disc.

3. The billhook begins to rotate and "grabs" the two strands of rope that are tightly wrapped around it to form a knot. Then, the claws on the billhook gradually open, and the rope disc is about to stop running.

4. As the billhook rotates, the claws on the billhook close and "bite" the rope, and the rope reaches the cutting position. At the same time, the needle has started to move downward from the top dead center of its travel and gradually moves to the starting position. During this process, the tying rope is introduced into the next notch of the disc.

5. As the rope release rod moves, the cutting knife cuts two ropes, and the semicircular notch of the rope release rod grasps the surface of the lower jaw of the billhook mouth, removing the knot from the billhook.

    At this point, the tying mechanism has completed a complete tying cycle.
