Description

Technical Field

[0001] The present invention relates to the technical field of casting machinery, in particular to a ladle feeding machine. Background Art

[0002] The ladle feeder is a mechanical device that uses a mechanical linkage to draw molten alloy from a furnace and deliver it to the die-casting machine's shot chamber along an ideal trajectory. The ladle feeder's transmission mechanism consists of a master arm and a slave arm, each driven synchronously by a separate motor. This synchronizes the movement of the master and slave arms, which in turn drive the ladle.

[0003] However, since the master arm group and the slave arm group are synchronously driven by different motion drive motors, this synchronous drive method itself has deviations, that is, there are deviations in the synchronization between the master arm group and the slave arm group. Especially as the running time increases, the deviation will become larger and larger, and the movement of the transmission mechanism will become less and less smooth and unstable, which will cause the alloy soup to overflow from the spoon.

During this period, when the soup noodle detection rod 61 with its detection end at the highest position contacts the soup surface, the three soup noodle detection rods 61 are short-circuited, the soup ladle 7 stops moving, and begins to take soup; during the soup taking process, two soup noodle detection rods 61 are short-circuited. When the soup noodle detection rod 61 with its detection end at the lowest position no longer contacts the soup surface, the two soup noodle detection rods 61 are no longer short-circuited, and the soup ladle 7 stops taking soup and begins to deliver soup.

In addition, the transmission mechanism adopts a four-bar structure, and there is only one connection between the main arm group and the slave arm group. Compared with the existing transmission mechanism using a four-bar structure, the curve range and stroke of the soup spoon movement are relatively large. In this way, the soup feeder no longer needs to be placed in an excessively high position, and it can also avoid some components, thereby making use of space.
