[0003] For example, an adjustment mechanism for an inkjet printer with the authorization announcement number "CN216268254U" is provided. By providing a base, a first stepper motor, a first transmission screw, a guide rod and a top plate, the lifting seat can be conveniently raised and lowered by the first transmission screw with the assistance of the guide sleeve, and the nozzle is raised and lowered by a screw drive, which is conducive to the precise adjustment of the nozzle height and can avoid damage to the nozzle caused by collision due to excessive movement speed. However, the adjustment mechanism for the inkjet printer has a connecting seat and a lifting seat that are in close contact. This causes friction between the connecting seat and the lifting seat when the connecting seat moves, thereby causing damage to the connecting seat and the lifting seat, increasing the maintenance cost of the adjustment structure. At the same time, when the adjustment mechanism for the inkjet printer needs to print on the inclined surface of an object, the nozzle angle of the inkjet printer cannot be adjusted, thereby increasing the working limitations of the adjustment structure.

[0026] Working principle:

[0027] When the position of the inkjet printer's print head needs to be adjusted:

[0028] Preparation stage:

[0029] First, the operator moves the base 1 to a suitable position through the threaded hole 12 so that the nozzle 10 can print the code on the equipment. Then the operator fixes the base 1 through the bolts and the threaded hole 12, and then turns on the external power supply of the first motor 2 and starts the first motor 2. The first motor 2 drives the reciprocating screw 3 to rotate, and the reciprocating screw 3 drives the cross plate 6 to move on the second slide bar 4. The cross plate 6 drives the slider 706 to move through the first slide bar 707, and the slider 706 drives the box 8 to move. The box 8 drives the nozzle 10 to move.

[0030] Horizontal movement stage of the nozzle:

[0032] Nozzle angle adjustment stage:

[0033] When it is necessary to inkjet the inclined surface of a material, the external power supply of the electric telescopic rod 901 is connected, and the electric telescopic rod 901 is started. The electric telescopic rod 901 drives the vertical rod 902 to move, and the vertical rod 902 drives the protrusion 903 to move.

The material is then inkjet-coded by the nozzle 10.
