Description

Technical Field

[0001] The present invention belongs to the technical field of pipe processing, and specifically relates to a waste PTFE pipe recycling device. Background Art

[0002] PTFE, whose full name is polytetrafluoroethylene, is a high-performance synthetic polymer material, known as the "king of plastics" due to its excellent properties. Also, due to its characteristics such as chemical stability, low friction coefficient, and high temperature resistance, it is often used as the inner lining of metal pipes. However, after long-term use, the pipes with PTFE as the inner lining will still show aging phenomena. Therefore, it is necessary to replace them and recycle the replaced waste PTFE pipes.

[0003] In the prior art, PTFE pipes are formed by extruding PTFE powder, and then they are forcibly pulled into seamless steel pipes. Since the outer diameter of the PTFE pipe is slightly larger than the inner diameter of the steel pipe, there is no gap between the steel pipe and the PTFE pipe used as the inner lining. When the inner lining PTFE pipe is long and aged, it is necessary to use cutting tools to cut the longer outer steel pipe together with the inner PTFE pipe into sections, and then use cutting tools to peel off the inner PTFE pipe.

[0004] In the prior art, during the process of peeling the waste PTFE pipe from the inside of the metal pipe, the outer metal pipe will be cut into sections together. Since most of the metal does not directly contact the liquid conveyed inside, there is no obvious aging phenomenon and it can still be used continuously. However, directly cutting the waste PTFE pipe and its outer metal pipe into sections undoubtedly destroys the reuse value of the outer metal pipe.

[0005] Therefore, the present invention provides a waste PTFE pipe recycling device. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0030] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0031] such as Figures 1 to 4As shown in the figure, a waste PTFE pipe recycling device according to an embodiment of the present invention includes a workbench 1; support seats 2 and a moving seat 3 are respectively arranged at both ends of the top surface of the workbench 1; the support seat 2 is fixedly connected to the workbench 1; the moving seat 3 is slidably connected to the workbench 1 and is driven by a servo motor; a connecting frame 4 is fixedly connected to one end of the moving seat 3 close to the support seat 2; rotating wheels 5 are installed at both ends of the bottom of the connecting frame 4 close to the ends, and the rotating wheel 5 on the side close to the moving seat 3 is driven by a servo motor; a diamond wire 6 is wound around the surfaces of the two rotating wheels 5; a docking column 7 is fixedly connected to one end of the connecting frame 4 close to the support seat 2; a docking groove 8 is formed at the corresponding position of the docking column 7 on the surface of the support seat 2, and the docking groove 8 is adapted to the docking column 7; a receiving groove 10 is formed on the top surface of the workbench 1 between the support seat 2 and the moving seat 3; a support plate 9 is slidably connected inside the receiving groove 10, and the support plate 9 is driven by a hydraulic system; a driving component is installed on the top surface of the support plate 9; the driving component is used to drive the pipe to be recycled to rotate and rise;During operation, in order to avoid damaging the external metal pipe during the recycling process of the waste PTFE pipe, the embodiments of the present invention can be used. Here, the pipe in which the metal pipe and the PTFE pipe are not yet separated is called the pipe to be separated. First, the user needs to place the pipe to be separated on the driving component at the receiving groove 10. Then, the moving seat 3 on one side of the workbench 1 will move towards the support seat 2 driven by the servo motor. During this process, the connecting frame 4 will be inserted into the interior of the pipe to be separated, and finally the docking column 7 at one end of the connecting frame 4 will be inserted into the docking groove 8 on the surface of the support seat 2. Subsequently, the servo motor drives the rotating wheel 5 to rotate, thereby driving the diamond wire 6 to rotate around the two rotating wheels 5. At this time, the driving component drives the pipe to be separated to rise, so that the PTFE pipe as the inner lining comes into contact with the diamond wire 6, and the two ends of the diamond wire 6 are at the same height as the inner wall of the bottom of the metal pipe. Thus, the diamond wire 6 rubs against the PTFE pipe, thereby realizing the cutting of the PTFE pipe. Since the diamond wire 6 has a diameter, after the diamond wire 6 cuts the PTFE pipe, a cut will be made on the surface of the PTFE pipe, and the cut surfaces on both sides are not in a fitting state. And because the two ends of the diamond wire 6 are at the same height as the inner wall of the bottom of the metal pipe, the bottom of the diamond wire 6 in the middle will stop after cutting to the inner wall of the metal pipe, thus avoiding damaging the metal pipe. Subsequently, the driving component drives the PTFE pipe away from the diamond wire 6, and then drives the pipe to be separated to rotate 180 degrees. Subsequently, the previous cutting operation is repeated. At this time, the PTFE pipe in the pipe to be separated will be cut into two non-connected parts. At the same time, because there is a cut between the two cut parts of the PTFE, the diameter of the complete pipe formed by splicing these two parts is smaller than that of the uncut PTFE pipe before. Therefore, the PTFE pipe can no longer tightly adhere to the inner wall of the pipe to be separated, so that the user can extract the PTFE pipe from the interior of the metal pipe and perform separate recycling treatment, thereby avoiding damaging the external metal pipe during the recycling process of the PTFE pipe, and thus affecting the normal use of the external metal pipe.

[0032] As Figures 3 to 4 shown, support arms 11 are provided at positions near the bottom of both ends of the connecting frame 4, and the two support arms 11 are symmetrically arranged; the ends of the support arms 11 away from the connecting frame 4 are rotatably connected to tensioning wheels 12; the diamond wire 6 is wound around the surfaces of the two rotating wheels 5 and the two tensioning wheels 12; during operation, when the driving component drives the pipe to be separated to rise, the tensioning wheels 12 at the ends of the support arms 11 will be located outside the pipe to be separated, and the bottom of the tensioning wheels 12 is lower than the bottom of the pipe to be separated. Thus, the tensioning wheels 12 at both ends can provide a downward pulling force for the diamond wire 6, so that the diamond wire 6 can closely adhere to the surface of the PTFE pipe, thereby improving the cutting efficiency of the PTFE pipe.

[0033] As Figures 3 to 4 shown, both sides of the rotating wheel 5 are rotatably connected with connecting discs 13, and the connecting discs 13 are fixedly connected with the connecting frame 4; an annular groove 14 is formed on the surface of the connecting disc 13; the support arm 11 is slidably connected with the annular groove 14; both sides of the support arm 11 are rotatably connected with traction plates 15; a pair of symmetrically arranged limiting grooves 16 are formed on both sides of the connecting frame 4; on the same side, the traction plates 15 are jointly fixedly connected with a connecting rod 17 at the limiting groove 16, and the connecting rod 17 is slidably connected in the limiting groove 16; a hydraulic rod 18 is fixedly connected between the two connecting rods 17; during operation, before the moving seat 3 drives the connecting frame 4 to extend into the pipeline to be separated, the hydraulic rod 18 in the connecting frame 4 will drive the connecting rods 17 on both sides to approach each other, and then drive the traction plates 15 on both sides to approach each other along the limiting grooves 16, so as to pull the support arm 11 through the traction plates 15, so that the support arm 11 slides along the annular groove 14 on the surface of the connecting disc 13, and then the tensioning wheel 12 deflects towards the direction of the connecting frame 4, so that the tensioning disc is retracted into the inner side of the connecting frame 4, so as to facilitate the connecting frame 4 to pass through the pipeline to be separated with a smaller diameter. When both ends of the connecting frame 4 are located outside the pipeline to be separated, the hydraulic rod 18 will drive the connecting rods 17 on both sides to move away from each other. At this time, the connecting rods 17 drive the traction plates 15 to move away from each other, so that the support arm 11 rotates in the direction away from the connecting frame 4, and the tensioning wheel 12 tightens the diamond rope 6 again. Then the user can normally cut the PTFE pipeline. By rotating the support arm 11, the total height between the connecting frame 4 and the support arm 11 can be shortened, so as to facilitate the connecting frame 4 to pass through the PTFE pipeline with a smaller diameter, and then the application range of the embodiment of the present invention is improved.

[0034] As Figure 1 , Figure 5 and Figure 6As shown, a push plate 19 is provided on one side of the support base 2 close to the docking groove 8; the push plate 19 is arranged in an annular structure; a pair of docking seats 20 are fixedly connected to the side of the push plate 19 away from the support base 2; a pair of convex blocks 21 are fixedly connected to the surface of the support base 2, and the line connecting the two convex blocks 21 is perpendicular to the line connecting the two docking seats 20; docking holes 22 are formed in the surface of the push plate 19 at positions corresponding to the convex blocks 21, and the docking holes 22 are adapted to the convex blocks 21; insertion holes 23 are formed in the side of the docking seat 20 away from the push plate 19; a plug rod 24 is fixedly connected to the surface of the docking column 7 at a position corresponding to the docking seat 20; a locking assembly is fixedly connected to the inside of the docking seat 20; the locking assembly is used to fix the plug rod 24 and the docking seat 20 together; during operation, when the docking column 7 is inserted into the docking groove 8 on the surface of the support base 2, the plug rod 24 on the surface of the docking column 7 will also be inserted into the inside of the docking seat 20 through the insertion hole 23. At this time, the locking assembly inside the docking seat 20 will lock the plug rod 24 and the docking seat 20 together. When the diamond wire 6 finishes cutting the PTFE pipe, the moving seat 3 drives the connecting frame 4 to move away from the support base 2. Since the push plate 19 is connected to the docking column 7 through the docking seat 20, the push plate 19 also moves away from the support base 2, so that the push plate 19 passes through the inside of the pipe to be separated, and then the cut PTFE pipe fragments inside the pipe to be separated are pushed out of the waste pipe, which further facilitates the user's recycling operation of the PTFE pipe fragments. Then, after the user clears the waste pipe at the driving assembly, the moving seat 3 will drive the connecting frame 4 to move towards the support base 2 again and insert the docking seat 20 back into the docking groove 8. At this time, the convex block 21 on the surface of the support base 2 will also be inserted into the docking hole 22 on the surface of the push plate 19. Then the user unlocks the docking seat 20 and the plug rod 24. At this time, the push plate 19 can be hung on the surface of the support base 2 through the cooperation of the convex block 21 and the docking hole 22, thus completing the reset operation of the push plate 19.

[0035] As Figure 7As shown, the locking component includes a conical cavity 25; the conical cavity 25 is formed inside the docking seat 20; the conical cavity 25 communicates with the jack 23; the end of the plug rod 24 is tapered; a metal cup 26 is arranged inside the conical cavity 25, and the metal cup 26 is adapted to the conical cavity 25; a through hole 27 is formed at one end of the metal cup 26 close to the jack 23; the metal cup 26 is made of magnetizable metal; a plurality of uniformly arranged receiving grooves 28 are formed on one side of the surface of the metal cup 26 close to the through hole 27; a ball 29 is arranged in the receiving groove 28; a connecting ring 30 is fixedly connected to the inner wall of the metal cup 26 on the side where the ball 29 is away from the through hole 27, and the connecting ring 30 is adapted to the through hole 27; a first spring 31 is fixedly connected between the connecting ring 30 and the inner wall of the docking seat 20; during operation, when the plug rod 24 is inserted into the docking seat 20 through the jack 23, the plug rod 24 will pass through the jack 23 and the through hole 27 at the end of the metal cup 26 and contact the ball 29 at the receiving groove 28. At this time, due to the frictional force, the plug rod 24 will drive the ball 29 and the metal cup 26 to move away from the jack 23. During this process, the metal cup 26 will compress the first spring 31 through the connecting ring 30. When the plug rod 24 is completely inserted into the metal cup 26, the first spring 31 will reset and push the metal cup 26 towards the jack 23. At this time, the ball 29 will move towards the inside of the metal cup 26 under the extrusion of the inner wall of the conical cavity 25, thereby clamping the plug rod 24 inside the metal cup 26. When the plug rod 24 is pulled in the direction away from the first spring 31 at this time, the plug rod 24 will drive the ball 29 and the metal cup 26 to move towards the jack 23 due to the frictional force between the plug rod 24 and the ball 29. At this time, since the diameter of the inner wall of the conical cavity 25 becomes smaller closer to the through hole 27, the extrusion force between the ball 29 and the plug rod 24 becomes greater, thereby locking the plug rod 24 and the docking seat 20 together. When the user needs to separate the plug rod 24 from the docking seat 20, the push plate 19 needs to be hung back on the surface of the support seat 2 again. At this time, the electromagnet block 32 on the surface of the support seat 2 is energized and generates magnetism, thereby sucking the metal cup 26 towards the push plate 19 and compressing the first spring 31. At this time, the inner wall of the cylindrical cavity can no longer extrude the ball 29, and the ball 29 will no longer extrude the plug rod 24. Thus, the plug rod 24 can be disengaged from between the balls 29, and then the plug rod 24 can be pulled out of the docking seat 20, thereby realizing the locking and unlocking between the plug rod 24 and the docking seat 20, without the user having to perform too many operations, thereby reducing the difficulty of use for the user and improving the usability of the embodiment of the present invention.

[0036] As Figures 6 to 7As shown, a sleeve 33 is sleeved on the end of the insertion rod 24 far from the docking column 7; a second spring 34 is fixedly connected between the surface of the sleeve 33 and the insertion rod 24; during operation, when the insertion rod 24 is inserted into the connection seat, the sleeve 33 will be blocked by the connection seat, causing it to move in the direction away from the tip of the insertion rod 24 and compress the second spring 34, so that the insertion rod 24 can be smoothly inserted into the inside of the docking seat 20. When the insertion rod 24 is pulled out from the inside of the docking seat 20, the compressed second spring 34 resumes and drives the sleeve 33 to move towards the tip of the insertion rod 24, finally covering the tip of the insertion rod 24 with the sleeve 33, thus preventing accidental injury caused by the user accidentally hitting it.

[0037] As Figure 5 shown, four evenly arranged extension plates 35 are provided on the surface of the push plate 19 on the side far from the support seat 2; baffles 36 are fixedly connected to both sides of the extension plates 35 on the surface of the push plate 19; a pressing rod 37 is threadedly connected to any one surface of a pair of the baffles 36, and the pressing rod 37 penetrates through the baffle 36; during operation, when the diameter of the PTFE pipe in the pipe to be separated is larger than the baffle 36, the user needs to move the extension plate 35 between the paired baffles 36. For this purpose, the user needs to first screw the pressing rod 37 so that it no longer presses the extension plate 35 between the paired baffles 36, and then the user slides the extension plate 35 so that the extension plate 35 moves away from the center of the push plate 19. After moving to a suitable position, by screwing the pressing rod 37 on the surface of the baffle 36, the position of the extension plate 35 is fixed, so that the extension plate 35 can replace the push plate 19 to contact the PTFE pipe, and then push the PTFE pipe out of the inside of the pipe to be separated, thereby improving the applicable range of the embodiment of the present invention.

[0038] As Figure 5 shown, an adjusting ring 38 is rotatably connected to the center of the circle at the middle part of the push plate 19; four evenly arranged adjusting rods 39 are rotatably connected to the side surface of the adjusting ring 38; the end of the adjusting rod 39 far from the adjusting ring 38 is rotatably connected to the extension plate 35; during operation, when the user needs to move the extension plate 35, the user can screw the adjusting ring 38 on the surface of the push plate 19. The adjusting ring 38 drives the adjusting rod 39 to deflect, and then drives the adjusting rod 39 to push or pull the extension plate 35, so as to realize the synchronous adjustment of multiple extension plates 35. When the user screws one of the pressing rods 37 to fix one of the extension plates 35, since the extension rod is connected to the adjusting ring 38 through the adjusting rod 39, the rotation of the adjusting ring 38 is also restricted, and then the positions of the other extension plates 35 are also fixed together. Thus, the user only needs to fix any one of the extension plates 35 to realize the synchronous fixation of the other extension plates 35, further improving the usability of the embodiment of the present invention.

[0039] As Figure 1 、 Figure 2 andFigure 8 As shown, the driving assembly includes a pair of symmetrically arranged driving seats 40; the driving seats 40 are fixedly connected to the top surface of the support plate 9, and the support plate 9 is driven by a hydraulic system; the top surfaces of the two driving seats 40 are rotatably connected with driving rollers 41, and the driving rollers 41 are driven by servo motors; a plurality of uniformly arranged strip-shaped protrusions 42 are fixedly connected to the surface of the driving rollers 41, and the strip-shaped protrusions 42 are made of rubber; during operation, when the pipeline to be separated is placed at the receiving groove 10, the support plate 9 will drive the two driving seats 40 to rise under the drive of the hydraulic system, and make the driving rollers 41 at the top of the driving seats 40 and the strip-shaped protrusions 42 on their surfaces contact the pipeline to be separated. At this time, the servo motor drives the driving rollers 41 to rotate, so that the rotation of the driving rollers 41 can drive the pipeline to be separated to rotate. At the same time, the strip-shaped protrusions 42 on the surface of the rotating rollers can increase the friction between the rotating rollers and the pipeline to be separated, thereby reducing the probability of slipping between the two.

[0040] As Figure 8 As shown, there is a gap between the two driving seats 40; a top plate 43 is slidably connected between the two driving seats 40 on the surface of the support plate 9, and the cross-section of the top of the top plate 43 is triangular; a guide plate 44 is fixedly connected to one side of the top of the workbench 1 close to the inclined surface of the top of the top plate 43; during operation, when the PTFE pipeline inside the pipeline to be separated is taken out, the top plate 43 in the middle of the support plate 9 rises, pushing the pipeline to be separated away from the rotating roller. Since the inclined surface of the top of the top plate 43 faces the guide plate 44, the pipeline to be separated will rotate towards the guide plate 44, and under the guidance of the guide plate 44, the pipeline to be separated will finally roll out of the top surface of the workbench 1, thus facilitating the blanking operation of the user.

[0041] During operation, in order to avoid damaging the external metal pipeline during the recycling process of the waste PTFE pipeline, the embodiments of the present invention can be used. Here, the pipeline in which the metal pipeline and the PTFE pipeline have not been separated is called the pipeline to be separated. First, the user needs to place the pipeline to be separated on the driving component at the receiving groove 10. Then, the moving seat 3 on one side of the workbench 1 will drive by the servo motor and move towards the support seat 2. During this process, the connecting frame 4 will be inserted into the interior of the pipeline to be separated by the moving seat 3, and finally the docking column 7 at one end of the connecting frame 4 will be inserted into the docking groove 8 on the surface of the support seat 2. Subsequently, the servo motor drives the rotating wheel 5 to rotate, thereby driving the diamond wire 6 to rotate around the two rotating wheels 5. At this time, the driving component drives the pipeline to be separated to rise, so that the PTFE pipeline serving as the inner lining contacts the diamond wire 6, and the two ends of the diamond wire 6 are at the same height as the inner wall of the bottom of the metal pipe. Thus, the diamond wire 6 rubs against the PTFE pipeline, thereby realizing the cutting of the PTFE pipeline. Since the diamond wire 6 has a diameter, after the diamond wire 6 cuts the PTFE pipeline, a cut will be made on the surface of the PTFE pipeline, and the two cut surfaces on both sides are not in a fitting state. Since the two ends of the diamond wire 6 are at the same height as the inner wall of the bottom of the metal pipe, the bottom of the diamond wire 6 in the middle will stop after cutting to the inner wall of the metal pipe, thus avoiding damaging the metal pipeline. Subsequently, the driving component drives the PTFE pipeline away from the diamond wire 6, and then drives the pipeline to be separated to rotate 180 degrees. Subsequently, the previous cutting operation is repeated. At this time, the PTFE pipeline in the pipeline to be separated will be cut into two unconnected parts. At the same time, since there is a cut between the two cut parts of the PTFE, the diameter of the complete pipeline formed by splicing these two parts is smaller than that of the uncut PTFE pipeline before. Therefore, the PTFE pipeline can no longer closely adhere to the inner wall of the pipeline to be separated, so that the user can extract the PTFE pipeline from the interior of the metal pipeline and perform separate recycling treatment, thus avoiding damaging the external metal pipeline during the recycling process of the PTFE pipeline and affecting the normal use of its external metal pipe.

[0042] When the driving component drives the pipeline to be separated to rise, the tensioning wheel 12 at the end of the support arm 11 will be located outside the pipeline to be separated, and the bottom of the tensioning wheel 12 is lower than the bottom of the pipeline to be separated. Thus, the two tensioning wheels 12 at both ends can provide a downward pulling force for the diamond wire 6, so that the diamond wire 6 can closely adhere to the surface of the PTFE pipeline, thereby improving the cutting efficiency of the PTFE pipeline.

[0043] Before the moving seat 3 drives the connecting frame 4 to extend into the pipeline to be separated, the hydraulic rod 18 inside the connecting frame 4 will drive the connecting rods 17 on both sides to approach each other, and then drive the traction plates 15 on both sides to approach each other along the limiting grooves 16, so as to pull the support arms 11 through the traction plates 15, making the support arms 11 slide along the annular groove 14 on the surface of the connecting disk 13, and then making the tensioning wheels 12 deflect towards the direction of the connecting frame 4, so that the tensioning disks are retracted inside the connecting frame 4, thus facilitating the connecting frame 4 to pass through the pipeline to be separated with a smaller diameter. When both ends of the connecting frame 4 are located outside the pipeline to be separated, the hydraulic rod 18 will drive the connecting rods 17 on both sides to move away from each other. At this time, the connecting rods 17 drive the traction plates 15 to also move away from each other, so that the support arms 11 rotate in the direction away from the connecting frame 4, and the tensioning wheels 12 tighten the diamond wire 6 again. Subsequently, the user can normally cut the PTFE pipeline. By the rotation of the support arms 11, the total height between the connecting frame 4 and the support arms 11 can be shortened, thus facilitating the connecting frame 4 to pass through the PTFE pipeline with a smaller diameter, and then improving the applicable range of the embodiment of the present invention.

[0044] When the docking column 7 is inserted into the docking groove 8 on the surface of the support seat 2, the insertion rod 24 on the surface of the docking column 7 will also be inserted into the inside of the docking seat 20 through the insertion hole 23. At this time, the locking component inside the docking seat 20 will lock the insertion rod 24 and the docking seat 20 together. When the diamond wire 6 finishes cutting the PTFE pipeline, the moving seat 3 drives the connecting frame 4 to move away from the support seat 2. Since the push plate 19 is connected to the docking column 7 through the docking seat 20, the push plate 19 also moves away from the support seat 2, so that the push plate 19 passes through the inside of the pipeline to be separated, and then pushes out the cut PTFE pipeline fragments inside the pipeline to be separated from the waste pipe, thus further facilitating the user's recovery operation of the PTFE pipeline fragments. Then, after the user clears the waste pipe at the driving component, the moving seat 3 will drive the connecting frame 4 to move towards the support seat 2 again and insert the docking seat 20 back into the docking groove 8. At this time, the convex block 21 on the surface of the support seat 2 will also be inserted into the docking hole 22 on the surface of the push plate 19. Then the user unlocks the docking seat 20 and the insertion rod 24. At this time, the push plate 19 can be hung on the surface of the support seat 2 through the cooperation of the convex block 21 and the docking hole 22, thus completing the reset operation of the push plate 19.

[0045] When the insertion rod 24 is inserted into the inside of the docking seat 20 through the insertion hole 23, the insertion rod 24 will pass through the insertion hole 23 and the through hole 27 at the end of the metal cup 26, and come into contact with the ball 29 at the receiving groove 28. At this time, due to the frictional force, the insertion rod 24 will drive the ball 29 and the metal cup 26 to move away from the insertion hole 23. During this process, the metal cup 26 will compress the first spring 31 through the connecting ring 30. And when the insertion rod 24 is completely inserted into the inside of the metal cup 26, the first spring 31 resets and pushes the metal cup 26 towards the insertion hole 23. At this time, the ball 29 will move towards the inside of the metal cup 26 under the extrusion of the inner wall of the conical cavity 25, so as to clamp the insertion rod 24 inside the metal cup 26. When the insertion rod 24 is then pulled in the direction away from the first spring 31, the insertion rod 24 will drive the ball 29 and the metal cup 26 to move towards the insertion hole 23 due to the frictional force between the insertion rod 24 and the ball 29. At this time, since the inner wall of the conical cavity 25 has a smaller diameter closer to the through hole 27, the extrusion force between the ball 29 and the insertion rod 24 is greater. Thus, the insertion rod 24 and the docking seat 20 are locked together. And when the user needs to separate the insertion rod 24 from the docking seat 20, the push plate 19 needs to be hung back on the surface of the support seat 2. At this time, the electromagnet block 32 on the surface of the support seat 2 is energized and generates magnetism, so as to suck the metal cup 26 towards the push plate 19 and compress the first spring 31. At this time, the inner wall of the cylindrical cavity can no longer extrude the ball 29, and the ball 29 will no longer extrude the insertion rod 24. Thus, the insertion rod 24 can be separated from between the balls 29, and then the insertion rod 24 can be pulled out of the docking seat 20. Thus, the locking and unlocking between the insertion rod 24 and the docking seat 20 are realized, and the user does not need to perform too many operations, thereby reducing the usage difficulty of the user and improving the usability of the embodiment of the present invention.

[0046] During the process of the insertion rod 24 being inserted into the connection seat, the sleeve 33 will be blocked by the connection seat, causing it to move away from the tip of the insertion rod 24 and compress the second spring 34, so that the insertion rod 24 can be smoothly inserted into the inside of the docking seat 20. After the insertion rod 24 is pulled out of the inside of the docking seat 20, the compressed second spring 34 resumes and drives the sleeve 33 towards the tip of the insertion rod 24, finally covering the tip of the insertion rod 24 with the sleeve 33, thus preventing the user from accidentally hitting and causing injury.

[0047] When the diameter of the PTFE pipe in the pipe to be separated is greater than that of the baffle 36, the user needs to move the extension plate 35 between the paired baffles 36. For this purpose, the user needs to first turn the extrusion rod 37 so that it no longer extrudes the extension plate 35 between the paired baffles 36. Then, the user slides the extension plate 35 so that the extension plate 35 moves away from the center of the push plate 19. After moving to the appropriate position, the position of the extension plate 35 is fixed by turning the extrusion rod 37 on the surface of the baffle 36, so that the extension plate 35 can replace the push plate 19 to contact the PTFE pipe, and then the PTFE pipe is pushed out of the interior of the pipe to be separated, thereby improving the applicable range of the embodiment of the present invention.

[0048] When the user needs to move the extension plate 35, the user can turn the adjusting ring 38 on the surface of the push plate 19. The adjusting ring 38 drives the adjusting rod 39 to deflect, and then drives the adjusting rod 39 to push or pull the extension plate 35, so as to realize the synchronous adjustment of multiple extension plates 35. When the user turns one of the extrusion rods 37 and fixes one of the extension plates 35, since the extension rod is connected to the adjusting ring 38 through the adjusting rod 39, the rotation of the adjusting ring 38 is also restricted, and then the positions of the other extension plates 35 are also fixed together. Thus, the user only needs to fix any one of the extension plates 35 to realize the synchronous fixation of the other extension plates 35, further improving the usability of the embodiment of the present invention.

[0049] When the pipe to be separated is placed at the receiving groove 10, the support plate 9 is driven by the hydraulic system to drive the two driving seats 40 to rise, and the driving rollers 41 on the tops of the driving seats 40 and the strip-shaped protrusions 42 on their surfaces are in contact with the pipe to be separated. At this time, the servo motor drives the driving rollers 41 to rotate, and the rotation of the driving rollers 41 can drive the pipe to be separated to rotate. At the same time, the strip-shaped protrusions 42 on the surface of the rotating roller can increase the friction between the rotating roller and the pipe to be separated, thereby reducing the probability of slipping between the two.

[0050] After the PTFE pipe inside the pipe to be separated is taken out, the top plate 43 in the middle of the support plate 9 rises to lift the pipe to be separated away from the rotating roller. Since the inclined surface on the top of the top plate 43 faces the guide plate 44, the pipe to be separated will rotate towards the guide plate 44, and under the guidance of the guide plate 44, the pipe to be separated will finally roll out of the top surface of the workbench 1, thus facilitating the user's blanking operation.
