When the printing work is performed, the trolley 400 drives the printing spray head to reciprocate along the guide rail, the printing spray head performs ink-jet printing on the printing medium, and as one end of the drag chain 200 is connected with the trolley 400, the trolley 400 drives the drag chain 200 to perform corresponding movement when moving. In the process that the drag chain 200 moves back and forth along with the trolley 400, the drag chain 200 sags or the drag chain 200 breaks under the action of gravity of the electric wire, the electric cable, the air pipe, the liquid pipe and the drag chain 200, so that when the drag chain upper section 201 passes over the drag chain lower section 202, the drag chain support mechanism 100 supports the drag chain upper section 201, and the drag chain upper section 201 is effectively prevented from sagging or breaking.
According to the digital printing machine provided by the application, the drag chain supporting mechanism 100 is adopted, when the drag chain 200 moves through the rubber coating roller 30, the drag chain 200 drives the rubber coating roller 30 to rotate around the central axis of the mandrel 20, so that rolling friction is generated between the drag chain 200 and the rubber coating roller 30, and the flexible rubber layer 32 is coated on the peripheral surface of the roller body 31, so that the flexible rubber layer 32 is in flexible contact with the drag chain 200, abnormal sound and noise generated by the drag chain 200 and the drag chain supporting mechanism 100 are small, meanwhile, abrasion and vibration of the drag chain 200 are reduced, the service life of the drag chain 200 is prolonged, the rubber coating roller 30 is matched with the mandrel 20, deformation is not easy, and the stability of supporting the drag chain 200 is improved.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
