An anti-scattering device is connected between the printing heads and the aperture so as to keep the UV beams away from the nozzles of the printing heads.

Abstract: An adjusting device for adjusting printing heads of inkjet printing machine includes a base connected to a printing unit and a plurality of printing assemblies are respectively connected to the base. Each printing assembly has a printing head connected thereto and a connection board is connected to an end wall of each printing assembly. Three adjusting members extend through the end board and contact against the end wall, and the three adjusting members are located at three peaks of an imaginary right triangle on the end board so as to adjust the printing head in different directions. A fourth adjusting member extends through the end board and is fixed to the end wall. The fourth adjusting member is located at a center of weight of the imaginary right triangle.
