The invention relates to the technical field of
digital printing machines, and discloses a double-cross-beam
digital printing machine, a printing trolley is slidably connected with a first cross beam and a second cross beam through mover plates on the two sides of the printing trolley, the double cross beams can provide huge lifting force, and meanwhile first sliding rails are arranged on the tops and the side faces of the cross beams; the first sliding rails are additionally arranged on the top and the side faces, so that the stress of the sliding rails is increased, and the running stability of the printing trolley can be improved under the huge weight of the printing trolley; the first sliding rail located at the top of the cross beam can increase
bearing capacity, and the first sliding rail located on the side face can improve operation precision. The printing trolley is driven through the
linear motor and the mover plates at the same time, the
linear motor is located above the cross beam, the structure is simple, the installation precision can be easily guaranteed, thrust can be easily increased, movers of the mover plates are powered on, the magnetic
induction effect is generated, thrust is also given to the printing trolley, meanwhile, the mover plates on the two sides are controlled in parallel, and therefore the printing trolley is more stable. Synchronous driving of the two mover plates can be guaranteed, driving force is kept synchronous, meanwhile, accurate control is achieved, and printing stability and precision are effectively guaranteed.
