Horizontal correction mechanism of three-dimensional list machine

The invention relates to a three-dimensional list machine, in particular to a horizontal correction mechanism of a three-dimensional list machine.

The three-dimensional lister is used for printing a three-dimensional structure, which generally has a substrate to carry the printed product, and the substrate is used as a horizontal reference when printing, so the substrate must be corrected to ensure accurate printing.

The printing mechanism of the lister is generally covered by a casing, and the cover is opened with an opening for taking out the finished product. Generally, the horizontal alignment method of the substrate is to connect three height adjustment mechanisms to three points on the substrate, and the three points need to be arranged in a triangle, and the three points on the substrate are adjusted to the same height by the height adjustment mechanism even if the substrate Horizontal configuration. However, the user can only adjust the height adjustment mechanism through the opening, so generally two of the height adjustment mechanisms are disposed adjacent to the opening for ease of operation. In order to arrange the three height adjustment mechanisms in a triangular shape, the other height adjustment mechanism must be disposed inside the list machine, which is not easily accessible through the opening, and therefore needs to be connected to an extension mechanism to extend to the opening for operation. The conventional horizontal correction mechanism has a complicated structure and is therefore expensive to manufacture and difficult to handle.
