[0048] Working principle:

[0049] 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 round the plate. The tensioning cylinder 3012 cooperates with the tensioning servo motor to tighten the 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.

[0050] 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. The sheet-shaped plate is placed on the roller body 102 and can advance or retreat to realize the purpose of sending the plate to the edge folding machine 2.

[0051] The edge folding machine 2 is composed of a frame 201, a roller line conveyor 2013, a left edge folding die body 206 and a right edge folding die body 203, a front positioning cylinder 2012, a left side positioning cylinder 208 and a right side positioning cylinder 204, and a left flattening cylinder 2010 and a right flattening cylinder 2011.

[0052] The roller line conveyor 2013 is composed of a conveyor drive motor 2014, a chain wheel and chain, and a conveying roller line, and is responsible for receiving and sending the sheet material.

[0053] The left flattening cylinder 2010 and the right flattening cylinder 2011 are responsible for flattening the plate to facilitate positioning.

[0054] The front positioning cylinder 2012, the left side positioning cylinder 208 and the right side positioning cylinder 204 fix the sheet material at the appropriate position to ensure the folding size.

[0055] 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 cylinders drive the edge folding dies to fold and form one end of the sheet material.

[0056] 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 and right positioning cylinders 208 and 204 push the sheet material to the side, so that the sheet material is completely positioned. The left and right flanging cylinders 207 and 205 simultaneously drive the bending dies to form flanges at both ends of the sheet material.

[0057] The round holding and seaming machine 3 is composed of a machine frame 301, a material taking manipulator body 305, a round holding barrel 307, a tensioning cylinder 3012, a lower round holding cylinder body 306, left and right round holding cylinders 3031 and 3032, a seaming die 309, a seaming cylinder 308, and a material taking manipulator 304.

[0058] The material taking manipulator body 305 is composed of left and right material taking manipulators 3023 and 3024 and a material taking manipulator up-down movement motor 3051. The material taking manipulator up-down movement motor 3051 drives the material taking manipulator body 305 to move up and down, the cylinders on the material taking manipulators 3023 and 3024 drive the material taking grippers 3021 and 3022 to move forward and backward, and the material taking grippers 3021 and 3022 are clamped under the drive of the cylinders. Thus, the whole manipulator can clamp the sheet material in the flanging machine 2, retreat into the round holding and seaming machine 3, and then be lifted to the round holding barrel 307 by the material taking manipulator up-down movement motor 3051.

[0059] The lower round holding cylinder body 306 is composed of a lower round holding cylinder up-down movement motor 3061 and a lower round holding cylinder group (lower round holding cylinders 3019, 3020, 3017, and 3018). The lower round holding cylinder group is driven by the lower round holding cylinder up-down movement motor 3061 to move up and down. After the flanged sheet material is tightly held by the round holding barrel 307, the lower round holding cylinder up-down movement motor 3061 drives the lower round holding cylinder group to rise to the round holding barrel 307, and the lower round holding cylinders 3019, 3020, 3017, and 3018 are sequentially extended to tightly hold the sheet material against the round holding barrel 307 by the inner barrel stop seat 9.

[0060] The left and right round holding device is composed of a left round holding cylinder 3031, a right round holding cylinder 3032 and a close contact wheel. The left round holding cylinder 3031 and the right round holding cylinder 3032 drive the close contact wheel to move left and right. 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.

[0061] 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.

[0062] At this time, the overlapping part of the two end flanges is just located in the seaming die 309, and 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.

[0063] 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.

[0064] 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.

[0065] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
