As shown in fig. 3 and 4, a feeding roller unit 9 is further disposed on the right side of the suction cup 4, and the feeding roller unit 9 includes a mounting plate 901, a second cylinder 902, a connecting bracket 903, an upper roller 904, a lower roller 905, and a roller box 906. The roller box 906 is a hollow box body made of a steel plate or an aluminum alloy material, and a lower roller 905 is arranged inside the roller box 906. Lower running roller 905 is cylindrical, and both ends area axis of rotation, surface have the friction decorative pattern, lower running roller 905 is steel running roller, aluminum alloy running roller or rubber running roller, the both ends of lower running roller 905 are passed through bearing movable mounting and are passed through on the both ends curb plate around roller case 906. The top of running roller case 906 is equipped with the quad slit, the length of quad slit is greater than down the length of running roller 905, the top of running roller 905 is arranged in the quad slit at running roller case 906 top down, just the top of running roller 905 upwards exposes 5-15mm from the quad slit at running roller case 906 top down. An upper roller 904 matched with the lower roller 905 is arranged right above the lower roller, two ends of the upper roller 904 are movably mounted on a connecting support 903, the upper end of the connecting support 903 is fixedly connected with a push rod of a second cylinder 902 in a stud connection or welding mode, the second cylinder 902 is fixed on a mounting plate 901 through bolts, the mounting plate 901 is rectangular and made of stainless steel or aluminum alloy materials, and the mounting plate 901 is fixedly mounted on a guide plate 725 or a rack 1 in a bolt or welding mode.

It should be noted that the supporting plate 3 in the present invention may also be a lifting supporting plate, the bottom of the lifting supporting plate is connected to the linear motion driving mechanism 805, the linear motion driving mechanism 805 is a cylinder driving mechanism, a hydraulic cylinder driving mechanism, a linear motor driving mechanism or a motor screw driving mechanism, and the linear motion driving mechanism 805 can push the lifting supporting plate to vertically move up and down, so as to adjust the height of the supporting plate 3.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-described embodiments. It should be noted that modifications and adaptations to those skilled in the art may occur to persons skilled in the art without departing from the spirit and scope of the present invention. All the components not specified in the present embodiment can be realized by the prior art.
