[0023] The working principle of the present invention is as follows: when in use, the second motor 703 is started, so that the driving roller 7 rotates with the transmission belt 702 to realize the transportation of the steel plate raw material. When it is necessary to receive the raw materials delivered from different platforms and to adjust the height of the U-shaped plate 302, the first motor 506 of the driving mechanism 5 is started, so that the driving gear 517 rotates with the driven gear 516, so that Figure 7The driving gear 517 shown rotates counterclockwise.

When the inclination of the U-shaped plate 302 needs to be adjusted, the first motor 506 is started to reverse, so that the arc-shaped slider 515 slides with the driven gear 516 toward the other side of the arc-shaped frame 513, so that the driven gear 516 is meshed with the third gear 509 on the other side, so that the worm 508 there drives the second worm gear 505 to rotate, and then the second gear 504 rotates with the first gear 603, so that the second reciprocating screw rod 601 rotates, so that the two second screw-connected plates 602 reciprocate toward and away from each other, so that the four support rods 605 rise and fall with the sliding rod 606, so that the sliding rod 606 slides inside the bar frame 607, so as to adjust the inclination of the U-shaped plate 302. In summary, in the present invention, through the arrangement of the second lifting mechanism 6, the first lifting mechanism 4 and the driving mechanism 5, the height adjustment of the transmission belt 702 is achieved through the forward and reverse rotation of the first motor 506, which is convenient for receiving steel plate raw materials transported from different platforms.
