[0078] As an optimization solution of the present invention, Figure 12 、 Figure 13 、 Figure 14 As shown, the guide member 7 includes a guide plate 701, a guide rod 702, a mounting plate 703, a push rod 704 and an adjusting member 706. The guide plates 701 are symmetrically arranged on both sides of the feeding and conveying roller 1, and the mounting plates 703 are symmetrically arranged on both sides of the center line of the guide plate 701, and the mounting plates 703 are fixedly installed on the side walls of the feeding and conveying roller 1. The guide rod 702 corresponds to the mounting plate 703, and the guide rod 702 is fixedly installed on the guide plate 701, and the guide rod 702 is slidingly connected to the mounting plate 703. The pushing rod 704 is fixedly installed in the middle of the guide plate 701, and a column 705 is fixedly installed at the end of the pushing rod 704. The adjusting member 706 is installed at the bottom of the feeding and conveying roller 1, and the adjusting member 706 is connected to the column 705 at the end of the pushing rod 704 on the guide plates 701 on both sides of the feeding and conveying roller 1.

[0079] The setting of the guide member 7 can guide the feeding conveying roller 1 when conveying the flange, ensuring the normal conveying of the flange. The setting of the adjusting member 706 can adjust the gap between the guide plates 701 arranged on both sides of the feeding conveying roller 1, ensuring that the guide plates 701 can guide flanges of different sizes, greatly improving the use scenarios of the device.

[0080] As an optimization solution of the present invention, Figure 13 、 Figure 14As shown, the adjusting member 706 includes a fixed plate 707, an adjusting motor 708, an adjusting rod 709 and a second pulling rod 7010 arranged at both ends of the adjusting rod 709.

The second pulling rod 7010 is arranged in the avoidance hole 101, and the two ends of the second pulling rod 7010 are respectively rotatably connected to the end of the adjusting rod 709 and the bottom of the column 705.

[0081] The setting of the adjustment member 706 can achieve the purpose of adjusting the distance between the guide plates 701 set on both sides of the feeding and conveying roller 1. The adjustment motor 708 drives the adjustment rod 709 to rotate, and the adjustment rod 709 rotates to pull one end of the second pulling rod 7010 to move. The movement of one end of the second pulling rod 7010 will pull the column 705 toward the middle of the feeding and conveying roller 1, thereby ensuring that the device can guide flanges of different sizes.

[0082] As an optimization solution of the present invention, Figure 12 As shown, a baffle 102 is provided on one end of the feeding conveying roller 1 close to the material transfer member 2 , and a limiting groove 103 for limiting the movement of the flange is opened on the baffle 102 .

[0083] The baffle 102 is set to block the flange to prevent it from falling off from the end of the loading and conveying roller 1 during transportation, thereby ensuring the safety of the flange during transportation. The setting of the limit groove 103 can limit the flange and prevent it from falling from the side wall of the loading and conveying roller 1, thereby greatly ensuring the safety of the flange.

[0084] The working process is as follows:

[0085] 1) Adjust the guide 7 according to the size of the flange;

[0086] The adjusting motor 708 drives the adjusting rod 709 to rotate, and the adjusting rod 709 rotates to pull one end of the second pulling rod 7010 to move. The movement of one end of the second pulling rod 7010 pulls the column 705 toward the middle or outer side of the feeding conveyor roller 1. The movement of the column 705 toward the feeding conveyor roller 1 drives the push rod 704 and the guide plate 701 to move toward the middle or outer side, ensuring that the flange to be polished can move along the feeding conveyor roller 1 to the baffle 102;

[0087] 2) Place the flanges to be polished on the feeding conveyor roller 1 continuously. The feeding conveyor roller 1 conveys the flanges to the baffle 102. The baffle 102 prevents the baffle 102 from falling from the other end of the feeding conveyor roller 1.

[0088] 3) Open the material transfer part 2, and the turning mechanism and the clamping mechanism 3 clamp the flange moved to the baffle 102 and transfer it;

[0089] When the regulating cylinder 207 is turned on to drive the moving block 209 to move along the guide rail 2010, the rotating column 2011 will be driven to follow the moving block 209 and move along the guide rail 2010. The movement of the rotating column 2011 will push the slider 206 to move. When the slider 206 moves, it will move along the strip hole 205 on the rotating arm 203. When the slider 206 moves, it will drive the rotating arm 203 to rotate along the rotating shaft 204. When the rotating arm 203 rotates, it will drive the flip mechanism and the clamping mechanism 3 to rotate until the clamping block 306 moves to the top of the feeding conveyor roller 1.

[0090] As the rotating arm 203 drives the clamping block 306 to continuously move above the upper conveying roller, the flip motor 601 is turned on to drive the first pulley 606 to rotate. The first pulley 606 drives the second pulley 604 to rotate through the synchronous belt 605. The rotation of the second pulley 604 drives the push-pull rod 305 to rotate. The rotation of the push-pull rod 305 drives the clamping block 306 to rotate until the clamping block 306 is parallel to the top of the upper conveying roller.

[0091] The contraction of the clamping cylinder 301 drives the lower rack 3012 to move, and the lower rack 3012 and the first gear 3014 rotate. The rotation of the first gear 3014 drives the upper rack 304 to move simultaneously toward the middle of the rotating arms 203 provided on both sides of the support plate 201. The upper rack 304 and the lower rack 3012 move toward the middle, driving the sliding rod 3010, the vertical rod 309, the push-pull rod 305 and the clamping block 306 to move toward the middle at the same time. Under the action of the clamping blocks 306 on the rotating arms 203 on both sides of the support plate 201, the flange is fixed;

[0092] 4) Reset the material transfer member 2, and complete the clamping of the flange under the action of the clamping mechanism 3. Then adjust the cylinder 207 to move in the opposite direction, driving the moving block 209 to rotate in the opposite direction along the guide rail 2010 until the rotating arm 203 is perpendicular to the support plate 201. While the rotating arm 203 rotates in the opposite direction, the flip mechanism 6 also drives the clamping mechanism 3 to rotate, ensuring that the surface of the flange to be polished is parallel to the polishing belt 504 on the polishing mechanism 5.

[0093] 5) Polish one side of the flange;

[0094] The extended lifting cylinder 503 drives the lifting frame 508 to move downward. The downward movement of the lifting frame 508 drives the first rotating roller 507, the second rotating roller 505, the third rotating roller 506 and the polishing belt 504 to move downward until the polishing belt 504 is in close contact with the surface of the flange. The driving motor 5011 is turned on to drive the rotating rod 5012 to rotate. The rotation of the rotating rod 5012 drives one end of the first pulling rod 5013 to move back and forth. The other end of the first pulling rod 5013 drives the half gear 5015 to rotate back and forth around the middle of the half gear 5015. The reciprocating rotation of the half gear 5015 drives the second gear 5014 to rotate back and forth. The reciprocating rotation of the second gear 5014 drives the first rotating roller 507 to rotate back and forth. The reciprocating movement of the first rotating roller 507 drives the polishing belt 504 to rotate back and forth. The reciprocating movement of the polishing belt 504 improves the purpose of polishing the flange surface.

[0095] 6) Replace the flange and polish the other side of the flange;

[0096] The lifting cylinder 503 drives the lifting frame 508 to move upward, and the upward movement of the lifting frame 508 drives the first rotating roller 507, the second rotating roller 505, the third rotating roller 506 and the polishing belt 504 to move upward, thereby driving the polishing belt 504 away from the flange to prevent interference between the flange and the polishing belt 504 when the flange is resurfaced;

[0097] Turn on the flip motor 601 to drive the first pulley 606 to rotate, and the first pulley 606 drives the second pulley 604 to rotate through the synchronous belt 605. The rotation of the second pulley 604 drives the push-pull rod 305 to rotate, and the rotation of the push-pull rod 305 drives the clamping block 306 to rotate until the clamping block 306 flips 180 degrees, achieving the purpose of changing the face of the flange;

[0098] The extended lifting cylinder 503 drives the lifting frame 508 to move downward. The downward movement of the lifting frame 508 drives the first rotating roller 507, the second rotating roller 505, the third rotating roller 506 and the polishing belt 504 to move downward until the polishing belt 504 is in close contact with the surface of the flange. The driving motor 5011 is turned on to drive the rotating rod 5012 to rotate. The rotation of the rotating rod 5012 drives one end of the first pulling rod 5013 to move back and forth up and down. The other end of the first pulling rod 5013 will drive the half gear 5015 to rotate back and forth around the middle of the half gear 5015. The reciprocating rotation of the half gear 5015 will drive the second gear 5014 to rotate back and forth. The reciprocating rotation of the second gear 5014 will drive the first rotating roller 507 to rotate back and forth. The reciprocating motion of the first rotating roller 507 will drive the polishing belt 504 to rotate back and forth. The reciprocating motion of the polishing belt 504 improves the purpose of polishing the flange surface.

[0099] 7) Place the polished flange on the unloading conveyor roller 4 and send it to the next process;

[0100] When the regulating cylinder 207 is turned on to drive the moving block 209 to move along the guide rail 2010, the rotating column 2011 will be driven to follow the moving block 209 and move along the guide rail 2010. The movement of the rotating column 2011 will push the slider 206 to move. When the slider 206 moves, it will move along the strip hole 205 on the rotating arm 203. When the slider 206 moves, it will drive the rotating arm 203 to rotate along the rotating shaft 204. When the rotating arm 203 rotates, it will drive the turning mechanism 6 and the clamping mechanism 3 to rotate until the clamping block 306 moves to the top of the feeding conveyor roller 1.

[0101] As the rotating arm 203 drives the clamping block 306 to continuously move above the upper conveying roller, the flip motor 601 is turned on to drive the first pulley 606 to rotate. The first pulley 606 drives the second pulley 604 to rotate through the synchronous belt 605. The rotation of the second pulley 604 drives the push-pull rod 305 to rotate. The rotation of the push-pull rod 305 drives the clamping block 306 to rotate until the clamping block 306 is parallel to the top of the unloading conveying roller 4.

[0102] The extension of the clamping cylinder 301 drives the lower rack 3012 to move, and the lower rack 3012 and the first gear 3014 rotate. The rotation of the first gear 3014 drives the upper rack 304 to move outward at the same time. The movement of the upper rack 304 and the lower rack 3012 will drive the sliding rod 3010, the vertical rod 309, the push-pull rod 305 and the clamping block 306 to move outward at the same time, releasing the clamping blocks 306 on the rotating arms 203 on both sides of the support plate 201 from clamping the flange, and placing the flange on the unloading conveying roller 4; so that the polished flange can be transported to the next process under the action of the unloading conveying pipe;

[0103] 8) Repeat the above steps to continuously polish the flange, which greatly improves the efficiency and quality of flange polishing.

[0104] The above content is merely an example and explanation of the structure of the present invention. Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner. As long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the scope of protection of the present invention.
