[0008] In one embodiment, a swing motor is fixed on the support, and the cutter swings up and down on the outside of the platform through the swing motor, which has a good cutting effect on the fabric.

[0009] In one of the embodiments, the output end of the swing motor is connected to a first swing arm, a second swing arm is fixedly provided at the bottom of the first swing arm, and the cutter is fixed on the second swing arm.

[0010] In one of the embodiments, a fixed knife seat is provided on the outer side of the platform, and the cutter cooperates with the knife seat through a swing motor to perform a shearing action, so that the cutting is stable.

[0011] Compared with the prior art, the cloth trimming device of the utility model has the following advantages:

[0012] By setting a swinging cutter and a knife holder, the edge of the passing fabric can be quickly cut and trimmed. By setting a pressing belt, the fabric can be pressed tightly to improve the stability of cutting and trimming. Thicker fabrics such as curtains can be trimmed quickly with high trimming accuracy and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
