AI Technical Summary
In existing food printers, there is a gap between the bearing and the screw thread when the lead screw is raised and lowered. This makes it difficult to ensure the horizontality when the lead screw is rotated synchronously during installation, affecting the parallelism between the printing platform and the printhead, and thus affecting the high-precision printing effect.
The first and second adjustment mechanisms are used to make coarse and fine adjustments to the vertical direction of the adjustment platform and the printing platform, respectively. Through the cooperation of components such as brackets, lead screws, arc grooves, stop rings, elastic elements and slide rails, multi-level adjustment is achieved to ensure the parallelism between the platform and the printhead.
It achieves high-precision parallelism adjustment between the food printer platform and the printhead, ensuring high-precision graphic printing results.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of food printers, and in particular to a leveling mechanism for a food printer. Background Technology
[0002] The existing food printer requires platform lifting and forward / backward movement. This is achieved through lead screw lifting and guide rails. During installation, the four lead screw bearings for platform lifting must be at the same level to ensure that the printing platform is parallel to the printhead. The printer relies on the coordinated operation of the X and Y axes to achieve high-precision graphic printing. To achieve high-precision printing, the plane error between the printing platform and the printhead must be within 0.5mm.
[0003] However, when the existing lead screw is used for lifting, there is a gap between the bearing and the screw thread, making it difficult to ensure the levelness when the lead screw is rotated during the installation of the timing belt. Utility Model Content
