[0032] When in use, the hydraulic rod 8 is controlled according to the diameter of the plate roller rolling workpiece 11 to adjust the height of the two support cylinders 10, the plate roller rolling workpiece 11 is placed on the support cylinder 10 and outside the plate rolling positioning mechanism 12, the motor 1 28 is controlled to operate the screw rod 29 to rotate, the screw block 30 moves left, and drives the pry bar 31 to rotate outward with the fixed movable rod 33 as the center of the circle to open, and the pry bar 31 slides outward through the movable groove 32 and the movable rod 33 to extend, so that the pry bar 31 contacts the left side of the plate roller rolling workpiece 11, and then the pry bar 31 continues to rotate, pushing the plate roller rolling workpiece 11 to move right, so that the right end of the plate roller rolling workpiece 11 pushes the push bar 18 and the gear rod 1 7 moves right, when the gear rod 17 moves right, the slide cylinder 14 slides leftward under the transmission of the gear 24, and the four support plates 36 are pushed outward by the connecting rod 38 to contact the inner surface of the plate roller rolling workpiece 11, thereby supporting and fixing the plate roller rolling workpiece 11 to prevent it from shaking left and right, front and back, and up and down during welding, thereby improving the welding quality and being able to adapt to the plate roller rolling workpiece 11 of different diameters and lengths; after use, the screw rod 29 is turned over by controlling the motor 1 28 to move the screw block 30 to the right, thereby driving the pry bar 31 to rotate and retract, so that its left end is close to the left end of the middle roller 13, and no longer blocks the left side of the plate roller rolling workpiece 11.

[0033] Reference Figure 2-3 Two support rods 21 are fixed at the bottom on the right side of the outer surface of the middle roller 13. The two support rods 21 are respectively slidably connected to the inside of the two through grooves 20 below. A support plate 22 is integrally formed at the bottom end of the support rod 21.

[0034] Reference Figure 1-9 An elastic metal plate 39 is fixed to the outer surface of the support plate 36, and the outer surface of the elastic metal plate 39 fits with the inner surface of the plate roller rolled workpiece 11. The elastic metal plate 39 has a certain elasticity on both sides. When encountering the internal curvature surface of the plate roller rolled workpiece 11 with different inner diameters, the elastic metal plate 39 is deformed under the squeezing of the support plate 36 and the inner wall of the plate roller rolled workpiece 11, so that the elastic metal plate 39 can better fit the inner wall of the plate roller rolled workpiece 11.

[0035] Reference Figure 1-2 Two motors 40 are fixed on the right side of the top plate 3. The left end of the output shaft of the motor 40 passes through the inside of the slide 4 and is fixed with a screw 7. The two screws 7 are threadedly connected to the slide 5. When the motor 40 is operated, the screw 7 rotates, so that the slide 5 drives the arc welding torch 6 to move left and right along the slide 4 to perform welding operations on the horizontal weld.

[0036] Reference Figure 8-9The outer surfaces of the two support tubes 10 are both in contact with the outer surface of the workpiece 11 below the plate roller. The support tube 10 supports the plate roller workpiece 11 and can assist the plate roller workpiece 11 to rotate when it is inserted, so that the weld is located below the arc welding torch 6 to select a better welding angle for operation.

[0037] Reference Figure 2 The left sides of the four push strips 18 are all in contact with the right side of the plate roller winding workpiece 11, and the right sides of the outer surfaces of the four pry bars 31 are all in contact with the left side of the plate roller winding workpiece 11, so that when the pry bars 31 rotate, they will push the left side of the plate roller winding workpiece 11, causing the plate roller winding workpiece 11 to move right, and the right end of the plate roller winding workpiece 11 will push the push strip 18 to move right, so that the subsequent mechanism can be transmitted and operated.

[0038] Reference Figure 2-9 A weld is provided on the top of the plate roller rolled workpiece 11, and the weld is located below the slideway 4 and above the upper elastic metal plate 39. The outer surface of the elastic metal plate 39 is provided with an anti-stick coating to reduce the welding affinity between the elastic metal plate 39 and the plate roller rolled workpiece 11; the top elastic metal plate 39 and the support plate 36 can support the bottom of the weld to prevent the metal at the weld from melting through and falling off during welding, thereby ensuring the integrity of the weld. Moreover, during welding, due to the concentration of heat, the plate roller rolled workpiece 11 may locally produce a large deformation, and the elastic metal plate 39 and the support plate 36 can play a role in supporting and reducing deformation.
