[0035] When the processed non-metallic pipe needs to be solidified, the staff connects the annular frame 3 with the air intake pipe, and the second connecting frame 9 with the air intake pipe. The staff places the non-metallic pipe on the pipe centering mechanism and starts the pipe centering mechanism. The pipe centering mechanism transports the non-metallic pipe to between the rotating frame 2 and the second ventilation pipe 8.

[0039] When curing the pipe, the staff adjusts the uniform air inlet mechanism according to the wall thickness of the pipe to help the pipe receive wind evenly.

[0040] Example 2

[0041] On the basis of Example 1, Figure 1 , Figure 5-Figure 8 As shown, the pipe centering mechanism includes a second fixed frame 11, the second fixed frame 11 is fixed to the side of the first fixed frame 1, a fixed seat 12 is fixed to the side of the second fixed frame 11, a first electric push rod 13 is fixed to the fixed seat 12, a support frame 14 is fixed to the telescopic end of the first electric push rod 13, the second fixed frame 11 is slidably connected to the first sliding frame 15, the first sliding frame 15 is fixed to the limiting protrusion 16, the second fixed frame 11 is slidably connected to the second sliding frame 17, the second sliding frame 17 is fixed to the first sliding frame 15, and the second sliding frame 17 is fixedly connected with a first stepper motor 18, and the output shaft of the first stepper motor 18 is fixedly connected with a first gear 19. The second fixed frame 11 is fixedly connected with a rectangular tooth plate 20 meshing with the first gear 19. The first stepper motor 18 drives the first sliding frame 15 to move to the left, so as to automatically load and unload the pipes, and seal the rotating frame 2 to prevent external airflow from affecting the solidification of the pipes. An inner wall support component for supporting the inner wall of the non-metallic pipe is arranged in the rotating frame 2, and an outer wall support component for fixing the outer wall of the non-metallic pipe is arranged in the rotating frame 2.

[0042] like Figure 1 , Figure 5-Figure 8As shown, the inner wall support assembly includes a rotating shaft 21, which is rotatably connected to the second ventilation pipe 8, a second stepper motor 22 is fixedly connected to the right side of the first fixed frame 1, the output shaft of the second stepper motor 22 is fixedly connected to the rotating shaft 21, a second gear 23 is fixedly connected to the left end of the rotating shaft 21, and three limiting support blocks 24 are rotatably connected to the left end of the second ventilation pipe 8, and the three limiting support blocks 24 are fixedly connected to a third gear 25 meshing with the second gear 23. The limiting support blocks 24 are driven to rotate by the second stepper motor 22 to fix the inner wall of the non-metallic pipe.

[0043] like Figure 1 , Figure 5-Figure 8 As shown, the outer wall support assembly includes a third stepper motor 26, the third stepper motor 26 is fixedly connected to the right side of the first fixed frame 1, the output shaft of the third stepper motor 26 is fixedly connected to the fourth gear 27, the first rotating plate 7 is circumferentially evenly spaced with first guide grooves 701, the right side of the first rotating plate 7 is provided with a second rotating plate 28 rotatably connected to the first fixed frame 1, the second rotating plate 28 is circumferentially evenly spaced with three second guide grooves 2801, the second rotating plate 28 is provided with a gear ring meshing with the fourth gear 27, the outer ring surface of the second rotating plate 28 is circumferentially evenly spaced with grooves matching with the cylindrical protrusions of the first limiting frame 32, the first guide groove 701 is slidably connected with a limiting sliding block 29, the limiting sliding block 29 is slidably matched with the adjacent second guide groove 2801, and is used to fix non The outer wall of the metal pipe is fixedly connected to the third fixing frame 30 on the right side of the first fixing frame 1, and the third fixing frame 30 is fixedly connected to two second electric push rods 31. The two second electric push rods are rotatably connected to the first limiting frame 32 at the telescopic ends through the connecting frame. The left side of the first limiting frame 32 is circumferentially evenly spaced with cylindrical protrusions. The outer ring surface of the first rotating plate 7 is circumferentially evenly spaced with through holes that cooperate with the cylindrical protrusions of the first limiting frame 32. The cylindrical protrusions of the first limiting frame 32 cooperate with the grooves of the second rotating plate 28 and the through holes of the first rotating plate 7 to fix the outer wall of the non-metallic pipe. The rotating shaft 21 is fixedly connected to the fifth gear 33 meshing with the fourth gear 27. The three limiting sliding blocks 29 are driven by the third stepping motor 26 to move toward the center of the second rotating plate 28 to fix the outer wall of the non-metallic pipe.

[0044] like Fig. 9 As shown, the air volume adjustment mechanism includes a sixth gear 34, which is fixed to the right end of the adjacent first ventilation pipe 6. The left side of the second rotating plate 28 is circumferentially evenly fixed with arc-shaped tooth plates 35 that mesh with the adjacent sixth gear 34. The second rotating plate 28 is used to rotate the first ventilation pipe 6 to adjust the angle of the ventilation hole on the first ventilation pipe 6.

[0045] When the processed non-metallic pipe needs to be solidified, the staff connects the annular frame 3 with the air intake duct, connects the second connecting frame 9 with the air intake duct, places the non-metallic pipe on the support frame 14, places the limiting protrusion 16 in the left end of the non-metallic pipe, starts the first stepper motor 18, and the output shaft of the first stepper motor 18 drives the first gear 19 to rotate. Under the action of the rectangular gear plate 20, the second sliding frame 17 drives the first sliding frame 15 to move to the left until the first sliding frame 15 seals the left end of the rotating frame 2 to prevent external air from entering the rotating frame 2 and affecting the solidification of the pipe. During this process, when the second ventilation pipe 8 enters the non-metallic pipe, the two first electric push rods 13 drive the support frame 14 to move downward.

[0046] When the first sliding frame 15 seals the left end of the rotating frame 2, the staff starts the second stepper motor 22, the second stepper motor 22 drives the second gear 23 to rotate through the movable shaft 21, and the second gear 23 drives the limit support block 24 to rotate through the three third gears 25. When the three limit support blocks 24 rotate to contact the inner wall of the non-metallic pipe, the third stepper motor 26 is started to support the left end of the non-metallic pipe through the three limit support blocks 24.

[0047] After the staff starts the third stepper motor 26, the third stepper motor 26 drives the second rotating plate 28 to rotate in the opposite direction through the fourth gear 27, and the second rotating plate 28 drives the three limit sliding blocks 29 to rotate through the second guide groove 2801. Under the limiting action of the three first guide grooves 701, the three limit sliding blocks 29 move toward the center of the second rotating plate 28 along the adjacent first guide grooves 701 respectively until the three limit sliding blocks 29 are in contact with the outer wall of the non-metallic pipe. Then, the second stepper motor 22 and the third stepper motor 26 are turned off, and the right end of the non-metallic pipe is fixed by the three limit sliding blocks 29. The pipe is supported and fixed by the cooperation of the three limit support blocks 24 and the three limit sliding blocks 29, and the wall thickness of the non-metallic pipe is determined to ensure that the non-metallic pipe gets the maximum ventilation when it is solidified, so as to avoid the inner wall of the pipe not being able to solidify evenly due to the lack of fixed pipe.

[0048] The staff starts the two second electric push rods 31, and the telescopic ends of the two second electric push rods 31 push the first limiting frame 32 to move leftward until the left end of the first limiting frame 32 completely enters the first rotating plate 7, and then stops the two second electric push rods 31. At this time, the second rotating plate 28 limits the first rotating plate 7 through the first limiting frame 32. At this time, the second stepper motor 22 and the third stepper motor 26 are started synchronously. The second stepper motor 22 transmits the rotation direction and speed of the second gear 23 through the rotating shaft 21, which are consistent with the third stepper motor 26 through the fourth gear The wheel 27 and the fifth gear 33 drive the second ventilation pipe 8 to rotate in the same direction and at the same speed, so that the rotation direction of the second rotating plate 28 is opposite to that of the second ventilation pipe 8. The second rotating plate 28 drives the three first connecting frames 5 to rotate in the opposite direction through the first limiting frame 32, the first rotating plate 7 and the rotating frame 2. The three first connecting frames 5 respectively drive the adjacent first ventilation pipes 6 to rotate in the opposite direction. The reverse rotation of the three first ventilation pipes 6 and the forward rotation of the second ventilation pipe 8 cooperate to accelerate the air flow rate on the surface of the non-metallic pipe and improve the curing efficiency of the metal pipe.

[0049] In the above process, the second rotating plate 28 rotates to transmit the sixth gear 34 to rotate through the arc-shaped tooth plate 35, and the sixth gear 34 drives the first ventilation pipe 6 to rotate, and adjusts the angle of the ventilation hole on the first ventilation pipe 6. According to the pipe diameter of different pipes, the first ventilation pipe 6 is adjusted to rotate at different angles to adjust the air outlet area of ​​the first ventilation pipe 6, change the different air flow rates in the rotating frame 2, and avoid extending the curing time of the pipe due to different wall thickness of the pipe.

[0050] After curing is completed, the staff turns off the second stepper motor 22 and the third stepper motor 26, and starts the first stepper motor 18. At this time, the output shaft of the first stepper motor 18 drives the first gear 19 to reverse. Under the action of the rectangular gear plate 20, the second sliding frame 17 drives the first sliding frame 15 to move to the left and reset to the initial state. During this process, the two first electric push rods 13 drive the support frame 14 to move upward and reset to the initial state.

[0051] After the support frame 14 is reset to the initial state, the staff starts the two second electric push rods 31, and the telescopic ends of the two second electric push rods 31 push the first limit frame 32 to move to the right until the first limit frame 32 is reset to the initial state, and the two second electric push rods 31 are stopped. At this time, the first limit frame 32 releases the limit on the second rotating plate 28, and the staff starts the second stepper motor 22 and the third stepper motor 26. At this time, the second stepper motor 22 and the third stepper motor 26 rotate in opposite directions, and the third stepper motor 26 drives the second rotating plate 28 to rotate through the fourth gear 27. The second rotating plate 28 drives the three limit sliding blocks 29 to rotate through the second guide groove 2801. Under the limiting action of the three first guide grooves 701, the three limit sliding blocks 29 are respectively reset to the initial state along the adjacent first guide grooves 701, and the fixation on the outer wall of the non-metallic pipe is released.

[0052] In the above process, the second rotating plate 28 rotates and drives the first ventilation pipe 6 to return to the initial state through the arc-shaped gear plate 35 and the sixth gear 34.

[0053] When the three limit sliding blocks 29 release the fixation on the outer wall of the non-metallic pipe, the staff turns off the third stepper motor 26. At this time, the second stepper motor 22 drives the limit support block 24 to rotate and reset to the initial state through the second gear 23 and the third gear 25, and releases the fixation on the inner wall of the non-metallic pipe. The staff takes out the solidified non-metallic pipe and repeats the above steps until all the non-metallic pipes are solidified. In the above process, the gas in the rotating frame 2 is discharged through the third connecting frame 10.

[0054] Example 3

[0055] On the basis of Example 2, Fig.10 and Fig.11 As shown, the uniform air intake mechanism includes symmetrically distributed sliding plates 36, which are rotatably connected to the first connecting frame 5, the first connecting frame 5 is fixedly connected to the fourth fixed frame 37, the fourth fixed frame 37 is slidably connected to the third sliding frame 38, the third sliding frame 38 and the adjacent sliding plates 36 are slidably connected, the third sliding frame 38 is fixedly connected to the elastic squeezing switch 39, the fourth fixed frame 37 is slidably connected to the second limit frame 40, the second limit frame 40 and the elastic squeezing switch 39 are limitedly slidably connected, the third sliding frame 38 is provided with a circular through hole, the second limit frame 40 is provided with a cylindrical protrusion, the circular through hole of the third sliding frame 38 cooperates with the cylindrical protrusion of the second limit frame 40 to limit the movement of the third sliding frame 38, and the third sliding frame 38 is used to drive the movement of the two sliding plates 36 to adjust the size of the air outlet in the middle and left and right parts of the first connecting frame 5.

[0056] Before curing the pipe, the staff presses the third sliding frame 38 according to the wall thickness of the pipe. The third sliding frame 38 drives the two adjacent sliding plates 36 to move, and adjusts the size of the air outlets in the middle and left and right parts of the first connecting frame 5. When the third sliding frame 38 moves to the specified position, the staff presses the elastic squeezing switch 39, which triggers the second limiting frame 40 to limit the third sliding frame 38, so as to help the pipe to be cured to be evenly exposed to the wind.

[0057] When curing the pipe, the exhaust device that conveys gas into the rotating frame 2 through the annular frame 3 and the second connecting frame 9 adjusts the speed of conveying gas into the rotating frame 2 according to the wall thickness of the non-metallic pipe determined by the cooperation of the three limit support blocks 24 and the three limit sliding blocks 29, and uniformly cures the metal pipes with different wall thicknesses by adjusting the size of the air outlets in the middle and the left and right parts of the first connecting frame 5, thereby avoiding prolonged curing time of the pipes due to different wall thicknesses.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
