The invention discloses an improved cloth cutting machine for garment production, which comprises a cutting device, an unwinding device, a frame body, a front conveying mechanism, a rear conveying mechanism and a motor. An unwinding device is arranged at the rear of the frame body. The front and rear ends of the frame body are respectively provided with a front conveying mechanism and a rear conveying mechanism, and a motor for driving the front conveying mechanism and the rear conveying mechanism is provided on the frame body, and the frame body is between the front conveying mechanism and the rear conveying mechanism A cutting device is provided, and the cutting device includes an upper mounting seat, a cylinder, an upper template, a lower template, a lower mounting seat and two positioning rods, and a support column is provided on the frame, and the upper end of the support column There is an upper mounting seat, and a slidable positioning rod is pierced on the upper mounting seat. Compared with the prior art, it can improve work efficiency, reduce labor intensity, good uniformity, easy to fix and disassemble the cloth roll, and reliable Well, avoid the situation where the cloth roll continues to rotate and unwind under the action of inertia, causing the cloth to fall to the ground.
