In the production and preparation process of gold powder ceramics, inkjet printers are one of the key pieces of equipment, mainly used to depict patterns on the surface of gold powder ceramics. A ceramic inkjet printer is disclosed in the existing authorization announcement document CN220865045U, including a machine body and a slot. A first baffle is provided on the front side of the machine body, a support plate is provided in the middle of the slot, a sliding groove is provided at the rear end of the support plate, a knob is provided in the middle of the baffle, a worm gear is fixedly connected to the rear side of the knob, the worm gear passes through the baffle and meshes with a worm wheel, a second threaded rod is fixedly connected to both sides of the worm wheel, a fixing block is provided on each of the second threaded rods, a second support rod is fixedly connected to the top of each fixing block, and an L-shaped support frame is fixedly connected to the top of each of the second support rods.
