A finished product conveyor belt 703 is provided on the conveying frame 702. After the finished product conveyor belt 703 conveys the finished carpet to a predetermined position on the conveying frame 702, the finished product conveyor belt 703 stops running. After the conveying frame 702 moves from the material receiving position to the stacking position, the finished product conveyor belt 703 conveys the finished carpet forward. At the same time, the conveying drive mechanism drives the conveying frame 702 to move in the direction of the material receiving position so that the finished carpet on the conveying frame 702 falls onto the stacking platform 701. The storage device 10, the conveying device 30, the punching device 40, the separating device 50, the stacking device 70, and the scrap collecting device 80 are all electrically connected to the control system 90.

[0028] In this embodiment, the carpet coming out of the storage device 10 is sent to the punching device 40 through the conveying device 30, and the carpet of a predetermined length is sent to the punching device 40 by the conveying device 30.

The conveying drive mechanism moves the conveying frame 702 to the stacking position. During the movement of the conveying frame 702, the finished product conveyor belt 703 stops transmission. When the conveying frame 702 moves to the stacking position, the finished product conveyor belt 703 starts to convey the carried finished carpet forward. At the same time, the conveying drive mechanism immediately drives the conveying frame 702 to move in the direction of the material receiving position, so that the finished carpet quickly falls on the stacking platform 701, so as to realize the stacking of the finished carpet.

[0030] In the above-mentioned embodiments, the present invention does not give a specific form of the conveying drive mechanism, but those skilled in the art will appreciate that there are a variety of options for this implementation, such as: the conveying drive mechanism is a manipulator, which drives the conveying frame 702 to move back and forth between the material receiving position and the stacking position; or the conveying drive mechanism is a screw rod plus a motor to realize the conveying frame 702 to move back and forth between the material receiving position and the stacking position, such as the conveying frame 702 is threadedly connected to the screw rod through a nut, wherein the screw rod is driven to rotate by the motor, and the rotation of the screw rod drives the conveying frame 702 to move in a straight line. Of course, other driving methods in the field that can drive the conveying frame 702 to move back and forth can also be selected to realize the conveying frame 702 to move back and forth between the material receiving position and the stacking position.

[0032] In this embodiment, the carpet from the storage device 10 is first transferred to the first conveyor belt 301, and the first conveyor belt 301 transfers the carpet to the punching device 40. After the punching device 40 completes the punching, the first conveyor belt 301 transfers the punched finished carpet. When the carpet is transferred to the input end of the first conveyor belt 301, the mobile pressing plate 302 at the first position is driven down by the first lifting assembly to press the carpet tightly on the first conveyor belt 301. After that, the mobile driving mechanism drives the mobile pressing plate 302 to move to the second position. In this way, the carpet is clamped by the mobile pressing plate 302 and transferred forward. To prevent the carpet from being displaced during the conveying process, when the carpet of a predetermined length is fed into the punching device 40, the second lifting assembly drives the fixed pressing plate 303 to descend (the mobile pressing plate 302 is reset at the same time), and the fixed pressing plate 303 presses the carpet, and then the punching device 40 performs punching.
