I.e. the weld to be welded is located on the symmetry plane of the two active rollers 1231.

Referring again to fig. 2 and 3, the present embodiment provides a conveying device 200 for conveying the tank 900 after the rolling process, mainly the tank 900 of the powder tanker, to the welding device 300 during the production process of the tank 900 after the rolling on the rolling device 100.

The conveying device 200 comprises a supporting frame 210, a walking frame 220 slidably connected to the supporting frame 210, and a supporting mechanism 230 carried on the walking frame 220; the supporting mechanism 230 is used to support the inner wall of the tank 900 and can move with the walking frame 220. After the sheet material is rolled and processed into a conical cylinder on the rolling device 100, the conical cylinder is carried by the supporting mechanism 230 and moved to the downstream welding device 300 to be welded under the driving of the traveling frame 220.

Referring again to fig. 2 and 3, in the present embodiment, the supporting frame 210 is located above the rolling mechanism 120. One end of the support frame 210, which faces away from the welding device 300, is connected to the edge rolling frame 110, and the other end of the support frame 210 is suspended.

In this embodiment, the supporting side frame 211 is located above the rolling device 100, and the length direction of the supporting side frame 211 is arranged along the longitudinal direction. The support cross member 212 is connected to the bottom of the opposite face of the support side frame 211 such that a slide groove, which is open at the upper portion and is at least longitudinally adjacent to one side of the welding apparatus 300, is formed between the two support side frames 211.

The support rails 213 are fixed to the upper surface of the support beam 212 in the longitudinal direction, and the upper ends of the support rails 213 are lower than the upper ends of the support side frames 211, so that the support rails 213 are positioned in the slide grooves formed by the two support side frames 211.

In this embodiment, two support rails 213 are provided at a lateral interval for supporting the traveling frame 220. One end of the support rail 213 facing the welding device 300 is flush with the support side frame 211 to ensure that the walking frame 220 can move from the support rail 213 to the welding device 300 more smoothly, so as to move the rounded can 900 to be welded to the welding device 300 smoothly.

Referring to fig. 7, the walking frame 220 is supported on the supporting rail 213 and can move on the supporting rail 213 along the longitudinal direction to drive the supporting mechanism 230 to move.

The traveling frame 220 includes two traveling longitudinal beams 221 arranged at a lateral interval, and a traveling cross beam 222 vertically connected to the two traveling longitudinal beams 221. The traveling longitudinal beams 221 are disposed in the lateral direction and slidably connected above the support rails 213.

In this embodiment, the traveling longitudinal beam 221 is longitudinally disposed on the support rail 213 and is positioned in the sliding groove formed by the support side frame 211 to move longitudinally on the support rail 213.

In some embodiments, the walking stringers 221 are sleeved on the support rails 213 via corresponding bushings.

A walking driving mechanism (not shown) is disposed between the walking frame 220 and the supporting frame 210, and is used for driving the walking frame 220 to move relative to the supporting frame 210.

In this embodiment, the traveling driving mechanism includes a rack fixed to the support frame 210 along the longitudinal direction, a traveling motor fixed to the traveling frame 220, and a gear connected to an output shaft of the traveling motor, and the gear is engaged with the rack. The traveling motor drives the gear to rotate, and the gear moves relative to the rack, so as to drive the traveling frame 220 to move relative to the support frame 210.

In some embodiments, corresponding racks are provided on the welding device 300 to enable the walking frame 220 to move on the welding device 300 downstream.

In other embodiments, the walking frame 220 has a sufficient length such that after the walking frame 220 moves to the welding device 300, a portion of the walking frame is still on the supporting frame 210, such that the walking frame 220 can move on the welding device 300.

The length of the walking frame 220 is greater than or equal to the length of the supporting mechanism 230, and the walking frame 220 is connected to the same longitudinal end of the supporting mechanism 230, so as to prevent the walking frame 220 from tilting in the longitudinal direction after the supporting mechanism 230 supports the tank 900.

Referring to fig. 7 and 8, the supporting unit 230 is disposed in a longitudinal direction and is inclined in the longitudinal direction to support the inner wall of the can 900 upward. The inclination angle of the supporting mechanism 230 is configured to keep the welding seam at the bottom of the can body 900 horizontal after the can body 900 is supported on the supporting mechanism 230, and the supporting mechanism 230 is driven by the walking frame 220 to move longitudinally onto the welding device 300, so as to keep the welding seam at the bottom of the can body 900 horizontal, and the can body 900 does not need to be turned over after moving onto the welding device, thereby facilitating the welding of the can body 900.

In this embodiment, the supporting mechanism 230 includes a supporting beam 231 disposed above the rolling device 100, and a plurality of sets of supporting units spaced on the supporting beam 231 along the length direction of the supporting beam 231. Each set of support units comprises a plurality of rolling members 232, all of the rolling members 232 are distributed along the arc surface to support the inner wall of the can body 900.

In this embodiment, the rolling members 232 are rotatably connected to the support beam 231, the rotation axis of the rolling members 232 is parallel to the length direction of the support beam 231, and all the rolling members 232 are distributed along the arc surface to support the inner wall of the tank 900. The tank 900 after being rolled up is prevented from being deformed due to the fact that the tank 900 falls down due to self weight in the process of rolling up the plate and the process of transporting the plate.

The supporting beam 231 is obliquely arranged in the longitudinal direction, specifically, the supporting beam 231 is obliquely arranged on a vertical plane passing through the axis of the tank body 900, so that the supporting beam 231 is matched with the taper of the tank body 900 of the powder tanker, and the tank body 900 can be effectively supported by the supporting unit on the supporting beam 231 during transportation and rolling.

In this embodiment, two supporting beams 231 are arranged at intervals along the transverse direction, and the two supporting beams 231 are connected by corresponding connecting rods. In the length direction from the second mounting seat 122 to the first mounting seat 121, the angle of inclination of the support beam 231 is made to be equal to the taper of the tank 900.
