The unwinding roller 1 rotates around the rotation axis thereof, the needle unwinding roller 2 rotates around the rotation axis thereof, and the cloth pressing roller 3 rotates around the rotation axis thereof. The rotation axis of the unwinding roller 1, the rotation axis of the unwinding needle roller 2 and the rotation axis of the cloth pressing roller 3 are parallel, and the cloth pressing roller 3 is positioned below the unwinding roller 1 and the unwinding needle roller 2. The first lifting device 31 is used for driving the cloth pressing roller 3 to move up and down. The base fabric sequentially bypasses the top of the unreeling needle roller 2, the bottom of the cloth pressing roller 3 and the bottom of the unreeling roller 1.

According to the technical scheme, the base fabric is fed into the tufting machine through the unwinding needle roller, the cloth pressing roller and the unwinding roller, the cloth pressing roller stably presses the base fabric when the base fabric is fed, the tension for enabling the base fabric to be flat and uniform is provided, and the base fabric is enabled to be kept flat in the feeding loom. Thus, the flat base fabric fed into the tufting machine improves the quality of the fabric and the market competitiveness of the fabric.
