The top of the limiting edge 36 has a U-shaped groove 361, which can pass through the short side of the L-shaped plate 3 to form a slot 362. The suction cup 262 below the lifting rod 253 lifts the pipe material, reducing friction during material turning. The L-shaped plate 3 rotates around the hinge 32 to change the state of the pipe material, achieving a flipping effect. The limiting edge 36 blocks the pipe material to prevent it from tipping over. The U-shaped groove 361 and slot 362 facilitate the insertion of the arm at the next station for easy material retrieval. The lifting rod 253 has threaded tubes 261 that slide on both sides to adjust the position of the suction cup 262, thus meeting the adsorption and extraction of pipe materials of different lengths. The conveyor frame 1 is rotatably connected to the pipe material feeder. The conveyor roller 11 supports the conveyor, and the boom 253 can move above the conveyor frame 1 to drive the suction cup 262 to adsorb the pipe material. The conveyor roller 11 on the conveyor frame 1 facilitates the feeding of the pipe material. The boom 253 can move above the L-shaped plate 3 and above the conveyor frame 1 to achieve the effect of transferring the pipe material.

The tops of the two guide rods 252 are connected to the connecting block 251. The bottom of the connecting block 251 is provided with a cylinder 24 corresponding to the top of the moving block 23. The output rod 241 of the cylinder 24 is connected to the bottom of the connecting block 251. The guide rods 252 increase the stability of the cylinder 24's up and down movement. Two guide rods 252 are connected to facilitate their up-and-down movement. The moving block 23 includes four moving wheels 231 on each side. The top of the platform frame 21 is equipped with a guide rail 232, allowing the moving wheels 231 to move along the guide rail 232 in the front-back direction.

Through the cooperation of the guide rail 232 and the moving wheels 231, the movement of the moving block 23 becomes more stable.The synchronous belt 273 can drive the movable block 23 to move. Either synchronous pulley 271 or synchronous pulley 272 is a drive wheel connected to the motor.

[0021] Please see Figure 2 - Figure 5 In this embodiment, a U-shaped block 26 slides on the boom 253, with the opening of the U-shaped block 26 facing downwards. A stop plate passes through the lower side wall of the U-shaped block 26. Threaded tubes 261 pass through the front and rear sides of the top of the base plate. A vent hole 2611 is provided at the axis of the threaded tube 261, and an air pipe can be connected to the vent hole 2611. A spiral adjusting rod 263 is engaged with the top of the U-shaped block 26. The spiral adjusting rod 263 can move downwards to press against the top of the boom 253. The hanging effect is achieved by the inverted U-shaped block 26. The two sides of the U-shaped block 26 can be limited on the boom 253. The vent hole of the threaded tube 261... 2611 can perform vacuum suction and vacuum breaking of suction cup 262. The cooperation between spiral adjusting rod 263 and the abutment plate can realize the positioning of U-shaped block 26. The bottom of L-shaped plate 3 is provided with block 2 34. The side wall of block 2 34 is provided with screw 2 341. The conveyor frame 1 is provided with a fixing plate 12 below the conveyor roller 11. The top of the fixing plate 12 is provided with block 1 121. Screw 2 341 and screw 1 122 protrude in the same direction. Cylinder 2 31 is rotatably connected to screw 2 341 and screw 1 122. Cylinder 2 31 includes output rod 2 311. The top of output rod 2 311 is provided with rotating ring 1 301. The bottom of cylinder 2 31 is provided with There is a rotating ring 302. A rotating ring 301 is fitted onto the outer diameter of a screw 341. A rotating ring 302 is fitted onto the outer diameter of a screw 122. A thrust ball bearing 351 is attached to the side of the rotating ring 301 away from block 34. A baffle 352 is provided on the side of the thrust ball bearing 351 away from block 34. A nut 353 is provided on the side of the baffle 352 away from block 34. A thrust ball bearing 131 is attached to the side of the rotating ring 302 away from block 121. A baffle 132 is attached to the side of the thrust ball bearing 131 away from block 121. The baffle 132 is located away from block 121. A nut 133 is provided on one side. The L-shaped plate 3 is pushed and rotated by a cylinder 31 that can rotate at both ends, so as to flip the pipe material on the L-shaped plate 3. The side of the baffle 132 and the side of the baffle 2352 near the block 234 are respectively provided with holes that mesh with screw 122 and screw 2341. The side of the baffle 132 and the side of the baffle 2352 near the block 234 are also respectively provided with grooves corresponding to thrust ball bearing 131 and thrust ball bearing 2351. The cooperation between thrust ball bearing 131 and thrust ball bearing 2351 reduces the friction of rotation and reduces the abnormal noise when the cylinder 231 is running.

[0022] During operation, the motor-driven chain transmission inside the conveyor frame 1 drives the conveyor roller 11 on the conveyor frame 1 to roll, so that the conveyor roller 11 carries the pipe material for conveying. After reaching the appropriate position, the sensor detects it, and then the cylinder 24 retracts, driving the lifting rod 253 to move downward. At the same time, the suction cup 262 adheres to the upper surface of the pipe material, which has been cleaned in the previous process. Then the suction cup 262 creates a vacuum on the pipe material. The cylinder 24 then extends the output rod 241 to drive the lifting rod 253 to move upward, thus lifting the pipe material. The motor at the synchronous pulley 272 drives the synchronous pulley 272 to rotate, which in turn drives the synchronous belt 273 to rotate, thereby causing the moving block 23 to slide. To prevent deviation, the moving block 23 moves backward until the lifting rod 253 is above the L-shaped plate 3. Then, cylinder 24 retracts, and the lifting rod 253, together with the suction cup 262, moves downward, thereby placing the pipe material on the L-shaped plate 3. Then, the suction cup 262 breaks the vacuum and separates from the pipe material. Then, cylinder 24 and synchronous wheel 272 return to the initial position to prepare for the next round of material suction. Cylinder 31 retracts, causing the L-shaped plate 3 to flip the material. The limiting edge 36 limits and blocks the pipe material. Then, the arm of the next station inserts into the U-shaped groove 361 and slot 362 to lift the pipe material from the L-shaped plate 3 for subsequent processing. The electrical wiring, program control and corresponding air circuits here are existing technologies, and their working principle will not be described in detail here.

[0023] Through the above steps, the threaded tubes 261 on the front and rear sides of the lifting rod 253 facilitate the adjustment of the position of the suction cup 262, thereby meeting the adsorption and extraction of pipe materials of different lengths. The suction cup 262 below the lifting rod 253 lifts the pipe material, reducing the friction generated when the pipe material is turned over. The L-shaped plate 3 rotates around the hinge 32 to change the state of the pipe material and achieve the effect of turning over. This solves the problem that the existing PE pipe production turning rack uses an integrated lifting device, which cannot contact and lift short pipe materials, and the sliding turning turning rack is prone to paint scratches during long-term use.
