Patent ID: 7399132

Claim:
A digital textile printer, comprising: a base supported by legs on the ground; a transfer belt being disposed on the base; a cartridge being transferable via the transfer belt; a head unit being fixed at one side of the cartridge; a driving panel being installed on the top of the base; a transfer motor being housed in said driving panel; a transfer axil having an elongated shape being coupled with said transfer motor; transfer rollers being disposed on the transfer axil, said transfer rollers protruding to a top of the base for moving a printing material in a forward direction; a feeding roller mechanism being installed in a rear of the base, said feeding roller mechanism being operable to send the printing material through the top of the base, said feeding roller mechanism including a rear bobbin axil; a rewinding roller mechanism operable for rewinding the printing material from the top of the base; at least one rear guiding roller mechanism being disposed at the rear of the base, said at least one rear guiding roller mechanism being coupled with the transfer axil; a rear feeding device including a rear tension mechanism which is disposed at a bottom of the rear of the legs operable to rotate eccentrically in a predetermined angle, a rear position sensor installed at a predetermined position of the rear tension mechanism to correspond to a rear eccentric axis of the rear tension mechanism winding the printing material, and a feeding motor installed on the top of the rear tension mechanism operable to drive said rear bobbin axil combined with a rear bobbin operable to feed the printing material by receiving signals from the rear position sensor; at least one front guiding roller mechanism being disposed at the front of the base, linked with the transfer axil; and a front rewinding device including a front tension mechanism which is disposed at the bottom of the front of the legs operable to rotate eccentrically in a predetermined angle, a front position sensor installed at a predetermined position of the front tension mechanism to correspond to a front eccentric axis of the front tension mechanism winding the printing material, and a rewinding motor installed on the top of the front tension mechanism to drive a front bobbin axis of the rewinding roller mechanism combined with a front bobbin rewinding the printing material by receiving signals from the front position sensor.
