With the side rod 13 and the corresponding U-shaped seat 12 rotating as a fulcrum, one group of first cylinders 8 or two groups of first cylinders 8 operate in coordination to adjust the distance between the two hinge plates 1, thereby solving the problem of large-sized and heavy plates being inconvenient to assemble.

Specifically as shown in Figures 1, 2 and 3, the plate tilting support moving mechanism includes a lead screw 2, a screw hole slider 3, a pneumatic suction cup 6 and a guide wheel 7. The sliders on the two lead screws 2 are connected to each other through an L-shaped steel 4, and a plurality of guide wheels 7 are rotatably installed on the inner wall of the L-shaped steel 4;

The limiting guide bottom bracket groove formed by the wheel groove structure on the guide wheels 7 is used to place the bottom edge of the plate, ensuring the convenience and effort of adjusting the plate back and forth on the inclined surface of the hinge plate. The two screws 2 rotating in the same group drive the connected screw hole sliders 3 along the strip groove 101, so that the L-shaped steel 4 connected by the screw hole sliders 3 and the plate located at the wheel groove of the guide wheel 7 move up along the surface of the hinge plate 1, which helps to put the top edges of the two plates together, speeds up the contact and splicing speed between the edges of the plates, and improves the welding effect.

The two rollers 16 are distributed in parallel, and each of the rollers 16 is rotatably installed between the two ends of the U-shaped long plate 15. The second cylinder 17 is distributed and installed at the bottom of the U-shaped long plate 15.

The two sets of second cylinders 17 are extended to move the rollers 16 connected by the U-shaped long plates 15 upward, so that the rollers 16 roll in contact with the back of the top edge of the plate that exceeds the top of the hinge plate 1, thereby supporting the top edge of the plate, preventing the top of the plate from shaking, and ensuring the accuracy of the edges of the two plates being pasted together.
