thus, the whole manipulator can clamp the sheet in the flanging machine 2, take it back into the round holding and seaming machine 3, and then lift it to the round holding barrel 307 through the material taking manipulator up and down movement motor 3051; the lower round holding cylinder body 306 is composed of a lower round holding cylinder up and down movement motor 3061 and a lower round holding cylinder set (a lower round holding cylinder one one 3019, a lower round holding cylinder one two 3020, a lower round holding cylinder two one 3017, and a lower round holding cylinder two two 3018); the lower round holding cylinder set is driven by the lower round holding cylinder up and down movement motor 3061 to move up and down, when the flange sheet is clamped to the round holding barrel 307, the lower round holding cylinder up and down movement motor 3061 drives the lower round holding cylinder set to rise to the round holding barrel 307, the lower round holding cylinder one one 3019, the lower round holding cylinder one two 3020, the lower round holding cylinder two one 3017, and the lower round holding cylinder two two 3018 are sequentially extended to tightly hold the sheet to the round holding barrel 307 through the inner cylinder stop seat 9;

at this time, the overlapping part of the two end flanges is located in the seaming die 309, the seaming cylinder 308 drives the seaming die 309 to press the overlapping part of the flanges into a tooth shape; thus, the two ends of the sheet are tightly clamped together; the material taking manipulator 304 is composed of a forward and backward movement cylinder 6, a turnover cylinder 7, and a clamping cylinder 8; the clamping cylinder 8 first clamps the cylinder, the forward and backward movement cylinder 6 sends the cylinder out of the round holding and seaming machine 3 to above the material taking roller 4, and the turnover cylinder 7 turns the cylinder by 90 degrees.

[0023] Working principle: When the present application is used, the inner barrel raw material enters the feeding roller 1 in the form of a flat plate, and is conveyed to the edge folding machine 2 through the roller. The edge folding machine 2 positions the plate and folds the two ends of the plate, one end by thirty degrees and the other end by negative thirty degrees. Then the material taking manipulator body 305 of the round holding and seaming machine takes out the folded plate and sends it to the round holding barrel 307 in the round holding and seaming machine 3. The lower round holding cylinder body 306 pushes the inner cylinder stop seat 9 to ascend and make the plate close to the round holding barrel 307, and the left round holding cylinder 3031 and the right round holding cylinder 3032 hold the plate round. The tensioning cylinder 3012 cooperates with the tensioning servo motor to tighten the positive thirty-degree and negative thirty-degree folded edges of the two ends of the plate. Then the seaming die 309 bites and seams the two ends of the folded edges to form a tooth-shaped tight seam. Finally, the discharging manipulator 304 puts the seamed cylinder at the discharging roller 4. When the diameter of the inner barrel of the washing machine is different, the lower round holding cylinder body 306 pushes the inner cylinder stop seat 9 to stop at different required positions, while the seaming position is fixed. In this way, the circumference of the inner barrel is different, and the diameter is also different.

[0024] The feeding roller 1 is composed of a frame 101, a roller body 102 and a drive motor body 103. The drive motor body 103 drives the chain, and the chain drives the roller body 102 to realize forward and reverse rotation.

[0027] The left flattening cylinder 2010 and the right flattening cylinder 2011 are responsible for flattening the plate to facilitate positioning.

[0028] The front positioning cylinder 2012, the left side positioning cylinder 208 and the right side positioning cylinder 204 fix the sheet material in the appropriate position to ensure the folding forming size.

[0029] The left edge folding die body 206 and the right edge folding die body 203 have edge folding dies and edge folding oil cylinders. The edge folding oil cylinder drives the edge folding die to fold and form one end of the sheet material.

[0030] The sheet material is fed from the left flanging die body 206 by the feeding roller 1 into the roller line conveyor 2013 of the flanging machine 2, which continues to convey the sheet material and feeds one end into the right flanging die body 203. The roller lifting cylinder 209 is lowered, and the left flattening cylinder 2010 and the right flattening cylinder 2011 are lowered to press the sheet material. The front positioning cylinder 2012 pushes the sheet material backward, and the left side positioning cylinder 208 and the right side positioning cylinder 204 push the sheet material to the side, so that the sheet material is completely positioned.

After the lower part of the sheet is closely held by the lower round holding cylinder body 306 and the lower part of the round holding barrel 307, the left round holding cylinder 3031 drives the close contact wheel to move right, and the right round holding cylinder 3032 drives the close contact wheel to move left, so that the sheet is also closely held on the upper part of the round holding barrel 307.

[0035] The tensioning cylinder 3012 is installed in the round holding barrel 307. After the sheet is closely held on the round holding barrel 307, the lower round holding cylinder body 306 is lowered, and the tensioning cylinder 3012 is extended, so that the sheet after being held is tensioned downward, and the two end flanges of the sheet can be buckled to each other.

[0036] At this time, the overlapping part of the two end flanges is just located in the seaming die 309, the seaming cylinder 308 drives the seaming die 309 to press the overlapping part of the flanges into a tooth shape. Thus, the two ends of the sheet are tightly buckled together.

[0037] The unloading manipulator 304 is composed of a front and rear movement cylinder 6, a turnover cylinder 7 and a clamping cylinder 8. The clamping cylinder 8 first clamps the cylinder, the front and rear movement cylinder 6 sends the cylinder out of the round holding and seaming machine 3 to the upper part of the unloading roller 4, and the turnover cylinder 7 turns the cylinder by 90 degrees.

[0038] The unloading roller 4 is composed of a frame and a non-powered roller. The unloading roller 4 is higher in front and lower in back, and the cylinder is placed on the roller line. Due to the action of gravity, the cylinder is conveyed to the end far from the equipment, which is convenient for unloading.
