[0023] A lead screw motor 3 is installed at one end of the drive cavity of the fixed bracket 1 along the feeding direction. The lead screw motor 3 is detachably connected to the fixed bracket 1. A ball screw 31 extends from the middle of the lead screw motor 3 in the feeding direction. One end of the ball screw 31 is rotatably connected to the lead screw motor 3, and the other end of the ball screw 31 is provided with a lead screw tailstock 32. A corresponding bearing is installed in the lead screw tailstock 32, and the ball screw 31 is rotatably connected to the bearing. The lead screw tailstock 32 is sleeved on the ball screw 31. The lead screw tailstock 32 is set on the second base plate 15 and is detachably connected to the second base plate 15.

[0024] It should be noted that the aforementioned feeding mechanism consists of two sets, each with its own control system to manage the start-up process of the lead screw motor. The two sets of feeding mechanisms operate alternately. One set starts first, feeding the fabric into the stamping area and pushing it out. Then, the other set starts and repeats the process. Once the first set has pushed the fabric out, the lead screw motor reverses, and the lead screw nut begins to retract to its initial position. At this point, the fabric from the other set has been stamped, and it pushes the fabric out, repeating the retraction process of the first set, thus achieving alternating operation between the two sets of feeding mechanisms.
[0025] Working principle:
[0026] In operation, this device first activates the control system. One lead screw motor starts working, the coupling drives the lead screw to rotate, and the lead screw nut moves linearly. This linear motion, connected to a connecting plate, pulls the slider on the slide rail. A material conveyor above the connecting plate feeds the material into the working area, and the punching machine begins punching the material. Then, the other lead screw motor starts, repeating the above workflow. After the first punching is complete, the lead screw motor starts again, pushing the fabric out. The motor then reverses, and the lead screw nut retracts until it reaches the waiting area. At this point, the other machine completes its punching and pushes the fabric out. This process repeats until the control system issues a stop command.
