[0029] The embodiment of the present invention provides a welding device for the frame support ring of a bag-type dust collector. As Figures 1-6 shown, it includes a base 1. A fixed seat 2 is fixedly connected to the top of the base 1. A driven roller 6 and a driving roller 7 are rotatably connected to one side of the fixed seat 2. A positioning roller 8 is arranged above the driven roller 6 and the driving roller 7. The driven roller 6, the driving roller 7 and the positioning roller 8 are parallel to each other. A lifting mechanism for controlling the height of the positioning roller 8 is arranged on the fixed seat 2. A stepping motor 12 is installed on the base 1. The stepping motor 12 is linked with the driving roller 7. A support ring body 3 is sleeved outside the driven roller 6, the driving roller 7 and the positioning roller 8. A side rib 4 is arranged on one side of the support ring body 3. A fixing mechanism 5 for fixing the position of the side rib 4 is arranged on the base 1.

[0030] During use, first, a plurality of support ring bodies 3 are sleeved on the outer sides of the driven roller 6, the driving roller 7, and the positioning roller 8 at equal intervals. Then, the lifting mechanism is activated. The lifting mechanism drives the positioning roller 8 to rise, and the positioning roller 8 drives the plurality of support ring bodies 3 to rise synchronously until the inner sides of the support ring bodies 3 are in mutual contact with both the driving roller 7 and the driven roller 6. At this time, the driven roller 6, the driving roller 7, and the positioning roller 8 completely support the support ring bodies 3, preventing the support ring bodies 3 from shaking. Then, the side ribs 4 are horizontally placed on the fixing mechanism 5, and the position of the side ribs 4 is adjusted by the fixing mechanism 5 until the side ribs 4 are in contact with the sides of the support ring bodies 3. Then, a welding machine is used to weld the side ribs 4 to the support ring bodies 3. After welding one side rib 4 is completed, the stepping motor 12 is activated. The stepping motor 12 drives the driving roller 7 to rotate, and the driving roller 7 drives the support ring body 3 to rotate by a certain angle. The next side rib 4 is placed on the fixing mechanism 5 and then welded. The rotation and welding operations are repeated until all the side ribs 4 are welded. After welding is completed, the lifting mechanism drives the positioning roller 8 to descend, and then the entire frame can be taken out. It can be used for welding support ring bodies 3 with different diameters. Compared with the traditional process, there is no need to repeatedly replace the tooling, which is convenient to use.

[0031] Anti-slip layers are fixedly connected to the outsides of both the driven roller 6 and the driving roller 7.

[0033] Through the arrangement of the first screw rod 14, the screw sleeves 15, and the rotating block 16 of the positioning roller 8, it is only necessary to adjust the distance between the rotating blocks 16 by rotating the screw sleeves 15 in advance. When placing the support ring body 3, it is only necessary to place the support ring body 3 in the arc-shaped groove of the rotating block 16, and the installation of the support ring body 3 can be quickly positioned, thus greatly improving the work efficiency, and the distance between the support ring bodies 3 can be conveniently adjusted as needed.

The guide rod 10 is vertically arranged, and the bottom end of the guide rod 10 is fixedly connected to the fixed seat 2. The top end of the guide rod 10 is fixedly connected with the limit plate 13. The lifting seat 9 is slidably fitted on the guide rod 10. One side of the fixed seat 2 is fixedly connected with a vertically arranged telescopic cylinder 11, and the output end of the telescopic cylinder 11 is fixedly connected to the lifting seat 9.

[0036] The horizontal heights of the driven roller 6 and the driving roller 7 are the same.

[0037] Two fixing mechanisms 5 are provided, and the two fixing mechanisms 5 are symmetrically arranged on both sides of the driving roller 7 in the length direction.

[0038] The fixing mechanism 5 includes a second screw 18, a mounting seat 17, a knob 20, an adjusting block 19, an outer tube 21, an inner tube 23, a fastening bolt 22, and a bracket 24. Two mounting seats 17 are provided, and the two mounting seats 17 are fixedly connected to the base 1. A second screw 18 is rotatably connected between the two mounting seats 17. One end of the second screw 18 penetrates through the mounting seat 17 and is fixedly connected to the knob 20. A screw hole matching the second screw 18 is formed in the adjusting block 19, and the adjusting block 19 is in threaded fit with the second screw 18. The top of the adjusting block 19 is fixedly connected with a vertically arranged outer tube 21. The inside of the outer tube 21 is hollow, and the inner tube 23 is slidably fitted inside the outer tube 21. A fastening bolt 22 for fixing the height of the inner tube 23 is installed at the top of the outer tube 21. The top of the inner tube 23 is fixedly connected with a bracket 24, and the bracket 24 is J-shaped.

[0039] Through the arrangement of the second screw 18, the knob 20, and the adjusting block 19 of the fixing mechanism 5, by rotating the knob 20, the knob 20 can drive the second screw 18 to rotate, and the rotation of the second screw 18 drives the adjusting block 19 to move back and forth. Through the arrangement of the outer tube 21 and the inner tube 23, the height can be adjusted, and then the height is fixed by the fastening bolt 22, so that it can be conveniently applied to the support ring body 3 with different diameters.

[0040] Working principle: When in use, first, a plurality of support ring bodies 3 are sleeved on the outer sides of the driven roller 6, the driving roller 7, and the positioning roller 8 at equal intervals. Then, the lifting mechanism is started. The lifting mechanism drives the positioning roller 8 to rise. The positioning roller 8 drives the plurality of support ring bodies 3 to rise synchronously until the inner sides of the support ring bodies 3 are in mutual contact with both the driving roller 7 and the driven roller 6. At this time, the driven roller 6, the driving roller 7, and the positioning roller 8 completely support the support ring bodies 3, so that the support ring bodies 3 will not shake. Then, the side rib 4 is horizontally placed on the fixing mechanism 5. The position of the side rib 4 is adjusted by the fixing mechanism 5 until the side rib 4 is in contact with the side surface of the support ring body 3. Then, the side rib 4 and the support ring body 3 are welded using a welding machine. After one side rib 4 is welded, the stepping motor 12 is started. The stepping motor 12 drives the driving roller 7 to rotate. The driving roller 7 drives the support ring body 3 to rotate by a certain angle. The next side rib 4 is placed on the fixing mechanism 5 and then welded. The rotation and welding operations are repeated until all the side ribs 4 are welded. After welding is completed, the lifting mechanism drives the positioning roller 8 to descend, and then the entire frame can be taken out. It can be used for welding support ring bodies 3 with different diameters. Compared with the traditional process, there is no need to repeatedly replace the tooling, which is convenient to use.
