A feeding device for a carpet printer, which relates to the technical field of printers. It comprises: a fixed frame; a movable frame assembled on fixed frame; a slide rail mounted on fixed frame; a slider provided on the lower side of movable frame, which can be slid relative to slide rail; a pneumatic uplift shaft rotationally assembled on movable frame for placing carpet rolls; a magnetic powder brake assembled on movable frame, and with one end assembled on one end of said pneumatic uplift shaft, which is used to play the role of controlling the tension when unwinding a roll; and, a magnetic powder brake assembled on fixed frame, and with one end connected to movable frame, for receiving a signal from a sensor detecting the offset of a carpet. a magnetic particle brake; and, a deflection correction device assembled on fixed frame and connected at one end to movable frame for driving movable frame to deflect relative to fixed frame when receiving a signal of deflection of the carpet detected by a sensor so as to realize deflection correction of the carpet.
With the above technical solution, the position of the carpet can be corrected in a timely manner, the stable tension of the carpet can be maintained, and the printing effect can be good.
