The second sliding frame 6 is arranged at the end of the clamping plate 5 away from the first sliding frame 1. The second forward and reverse screw 8 and two groups of symmetrically arranged second sliders 9 are arranged in the second sliding frame 6. The auxiliary plate 10 is U-shaped. The second slider 9 is threadedly connected with the second forward and reverse screw 8. The output end of the second motor 7 passes through the second sliding frame 6 and is connected to the second forward and reverse screw 8. One end of the auxiliary plate 10 is connected to the second slider 9, and the other end of the auxiliary plate 10 is arranged between the two groups of clamping plates 5.

[0023] During actual use, the material is placed on the support assembly and further manually adjusted at a certain angle. Initially, the distance between the two groups of first sliders 4 and second sliders 9 is large. The second motor 7 is started, and the second motor 7 drives the second forward and reverse screw 8 in the second slide frame 6 to rotate. The two groups of second sliders 9 move toward each other, and the auxiliary plate 10 on the second slider 9 contacts the material to align the material front and back. The first motor 2 is started, and the first motor 2 drives the first forward and reverse screw 3 in the first slide frame 1 to rotate.
