Description

Technical Field

[0001] The invention belongs to the technical field of pipe processing, in particular to a waste PTFE pipe recycling device. Background Art

[0002] PTFE, the full name of which is polytetrafluoroethylene, is a high-performance synthetic polymer material. It is known as the "King of Plastics" for its outstanding performance. It is often used as the lining of metal pipes due to its chemical stability, low friction coefficient, high temperature resistance and other characteristics. However, after long-term use, pipes lined with PTFE will still age. For this reason, they must be replaced and the replaced waste PTFE pipes must be recycled.

[0003] The PTFE pipe in the prior art is a pipe formed by extruding PTFE powder, which is then forcibly pulled into a seamless steel pipe. 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 serving as an inner lining. When the PTFE pipe serving as an inner lining grows long and ages, it is necessary to use a cutting tool to cut the longer outer steel pipe together with the inner PTFE pipe into sections, and then use the cutting tool to peel off the inner PTFE pipe.

[0004] In the prior art, during the process of stripping the waste PTFE pipe from the inside of the metal pipe, the external metal pipe is cut into sections together. Since most of the metal does not directly contact the liquid transported inside, it does not show obvious aging and can still be used. However, directly cutting the waste PTFE pipe and its external metal pipe into sections will undoubtedly destroy the reuse value of the external metal pipe.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 4As shown, a waste PTFE pipe recycling device described in an embodiment of the present invention comprises a workbench 1; a support seat 2 and a moving seat 3 are respectively arranged at the two 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 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 the bottom of the connecting frame 4 close to the two ends, and the rotating wheel 5 close to the side of the moving seat 3 is driven by a servo motor; the two rotating wheels The surface of the wheel 5 is wound with a diamond rope 6; the end of the connecting frame 4 close to the support seat 2 is fixedly connected with a docking column 7; the surface of the support seat 2 is provided with a docking groove 8 at a position corresponding to the docking column 7, and the docking groove 8 is adapted to the docking column 7; the top surface of the workbench 1 is provided with a receiving groove 10 between the support seat 2 and the moving seat 3; the receiving groove 10 is slidably connected with a support plate 9, and the support plate 9 is driven by a hydraulic system; the top surface of the support plate 9 is installed with a driving assembly; the driving assembly is used to drive the pipeline to be recovered to rotate and rise;During operation, in order to avoid damaging the metal pipe on the outside of the waste PTFE pipe during the recycling process, the embodiment of the present invention can be used. Here, the pipe that has not yet completed the separation of the metal pipe and the PTFE pipe 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, and then the moving seat 3 on one side of the workbench 1 will be driven by the servo motor to move toward the support seat 2. During this process, the moving seat 3 will insert the connecting frame 4 into the interior of the pipe to be separated, and finally insert the docking column 7 at one end of the connecting frame 4 into the docking groove 8 on the surface of the support seat 2. Then the servo motor drives the rotating wheel 5 to rotate, and then drives the diamond rope 6 to rotate around the two rotating wheels 5. At this time, the driving component drives the pipe to be separated to rise again, so that the PTFE pipe serving as the lining contacts the diamond rope 6, and the two ends of the diamond rope 6 are consistent in height with the inner wall of the bottom of the metal pipe, so that the PTFE pipe is rubbed by the diamond rope 6, thereby realizing the cutting of the PTFE pipe. Since the diamond rope 6 has a diameter, the diamond rope 6 is used for rubbing the PTFE pipe. After cutting, a cut will be cut on the surface of the PTFE pipe, and the cut surfaces on both sides are not in a fitted state. Since the two ends of the diamond rope 6 are at the same height as the inner wall of the bottom of the metal pipe, the bottom of the diamond rope 6 in the middle will stop after cutting the inner wall of the metal pipe, thereby avoiding damage to the metal pipe. Then the driving component drives the PTFE pipe away from the diamond rope 6, and then drives the pipe to be separated to rotate 180 degrees, and then repeats the previous cutting operation again. At this time, the PTFE pipe in the pipe to be separated will be cut into two unconnected parts. At the same time, since there is a cut between the two parts of the PTFE cut, the diameter of the complete pipe assembled from the two parts is smaller than the PTFE pipe that has not been cut before. Therefore, the PTFE pipe can no longer be tightly attached to the inner wall of the pipe to be separated, so that the user can pull the PTFE pipe out of the metal pipe and recycle it separately, thereby avoiding damage to the metal pipe outside during the recycling process of the PTFE pipe, thereby affecting the normal use of the metal pipe outside. ;

[0032] like Figure 3 to Figure 4 As shown, support arms 11 are provided at both ends of the connecting frame 4 near the bottom, 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 the tensioning wheels 12; the diamond rope 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 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, thereby the tensioning wheels 12 at both ends can provide downward pulling force for the diamond rope 6, so that the diamond rope 6 can be close to the surface of the PTFE pipe, thereby improving the cutting efficiency of the PTFE pipe.

[0033] like Figure 3 to Figure 4 As shown, both sides of the rotating wheel 5 are rotatably connected with connecting plates 13, and the connecting plates 13 are fixedly connected to the connecting frame 4; an annular groove 14 is provided on the surface of the connecting plate 13; the support arm 11 is slidably connected to 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 provided on both sides of the connecting frame 4; the traction plates 15 on the same side are commonly 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 groove 16, so as to pull the support arm 1 through the traction plate 15 1, so that the support arm 11 slides along the annular groove 14 on the surface of the connecting disk 13, thereby causing the tensioning wheel 12 to deflect toward the direction of the connecting frame 4, so that the tensioning disk is received into the inner side of the connecting frame 4, thereby facilitating the connecting frame 4 to pass through the pipe to be separated with a smaller diameter, and when both ends of the connecting frame 4 are located outside the pipe to be separated, the hydraulic rod 18 will drive the connecting rods 17 on both sides to move away from each other, and at this time, the connecting rods 17 drive the traction plates 15 to move away from each other, thereby causing the support arm 11 to rotate in the direction away from the connecting frame 4, and causing the tensioning wheel 12 to tighten the diamond rope 6 again, and then the user can cut the PTFE pipe normally, and through the rotation of the support arm 11, the total height between the connecting frame 4 and the support arm 11 can be shortened, thereby facilitating the connecting frame 4 to pass through the PTFE pipe with a smaller diameter, thereby improving the scope of application of the embodiment of the present invention.

[0034] like Figure 1 , Figure 5 and Figure 6As shown, a push plate 19 is provided on one side of the support seat 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 seat 2; a pair of protrusions 21 are fixedly connected to the surface of the support seat 2, and the connection line between the two protrusions 21 and the connection line between the two docking seats 20 are perpendicular to each other; a docking hole 22 is opened on the surface of the push plate 19 at a position corresponding to the protrusion 21, and the docking hole 22 is adapted to the protrusion 21; the docking seat 20 is away from A plug hole 23 is provided on one side of the push plate 19; a plug rod 24 is fixedly connected to the surface of the docking column 7 at the corresponding position of the docking seat 20; a locking component is fixedly connected to the inside of the docking seat 20; the locking component is used to fix the plug rod 24 and the docking seat 20 together; when working, when the docking column 7 is inserted into the docking groove 8 on the surface of the support seat 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 plug hole 23, and at this time, the locking component inside the docking seat 20 will lock the plug rod 24 with the docking seat 2 0 is locked together, and when the diamond rope 6 completes the cutting of the PTFE pipe, the moving seat 3 drives the connecting frame 4 to move in the direction away from the supporting seat 2, and since the push plate 19 is connected to the docking column 7 through the docking seat 20, the push plate 19 also moves in the direction away from the supporting seat 2, so that the push plate 19 passes through the interior of the pipe to be separated, and then pushes the cut PTFE pipe fragments inside the pipe to be separated out of the waste pipe, thereby further facilitating the user's recovery operation of the PTFE pipe fragments, and then after the user cleans up the waste pipe at the driving assembly, the moving seat 3 will drive the connecting frame 4 to move toward the supporting seat 2 again, and reinsert the docking seat 20 into the docking groove 8, at this time, the protrusion 21 on the surface of the supporting seat 2 will also be inserted into the docking hole 22 on the surface of the push plate 19, and then the user unlocks the docking seat 20 and the insertion rod 24, and at this time the push plate 19 can be hung on the surface of the supporting seat 2 through the cooperation of the protrusion 21 and the docking hole 22, thereby completing the reset operation of the push plate 19.

[0035] like Figure 7As shown, the locking assembly includes a tapered cavity 25; the tapered cavity 25 is provided inside the docking seat 20; the tapered cavity 25 is communicated with the insertion hole 23; the end of the insertion rod 24 is tapered; a metal cup 26 is provided inside the tapered cavity 25, and the metal cup 26 is adapted to the tapered cavity 25; a through hole 27 is provided at one end of the metal cup 26 close to the insertion hole 23; the metal cup 26 is made of magnetizable metal; a plurality of evenly arranged receiving grooves 28 are provided on the side of the surface of the metal cup 26 close to the through hole 27; a ball 29 is provided in the receiving groove 28; the inner wall of the metal cup 26 and the side of the ball 29 away from the through hole 27 are fixedly connected There is a connecting ring 30, and the connecting ring 30 is adapted to the through hole 27; a spring 31 is fixedly connected between the connecting ring 30 and the inner wall of the docking seat 20; the surface of the support seat 2 is inlaid with an electromagnet block 32 at the docking seat 20; when working, when the insertion rod 24 is inserted into the docking seat 20 through the socket 23, the insertion rod 24 will pass through the socket 23 and the through hole 27 at the end of the metal cup 26, and contact with the ball 29 at the accommodating groove 28. At this time, due to the friction force, the insertion rod 24 will drive the ball 29 and the metal cup 26 to move away from the socket 23. In this process, the metal cup 26 will compress the spring 31 through the connecting ring 30, and when the insertion rod 24 is fully inserted into the metal cup 26, the metal cup 26 will compress the spring 31. After the metal cup 26 is inserted into the socket 23, the spring 31 is reset and pushes the metal cup 26 toward the socket 23. At this time, the ball 29 will move toward the inside of the metal cup 26 under the pressure of the inner wall of the tapered cavity 25, thereby clamping the insertion rod 24 inside the metal cup 26. At this time, when the insertion rod 24 is pulled in the direction away from the spring 31, the friction between the insertion rod 24 and the ball 29 drives the ball 29 and the metal cup 26 to move toward the socket 23. At this time, since the inner wall of the tapered cavity 25 is closer to the through hole 27 and the diameter is smaller, the squeezing force between the ball 29 and the insertion rod 24 is greater, thereby locking the insertion rod 24 and the docking seat 20 together. When the user needs to When the insertion rod 24 is separated 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, thereby sucking the metal cup 26 toward the push plate 19 and compressing the spring 1 31. At this time, the inner wall of the cylindrical cavity can no longer squeeze the ball 29, and the ball 29 will no longer squeeze the insertion rod 24. As a result, the insertion rod 24 can be detached from between the ball 29, and the insertion rod 24 can be pulled out of the docking seat 20, thereby realizing the locking and unlocking between the insertion rod 24 and the docking seat 20, and the user does not need to perform too much operation, thereby reducing the difficulty of use for the user and improving the ease of use of the embodiment of the present invention.

[0036] like Figure 6 to Figure 7As shown, a sleeve 33 is sleeved on one end of the insertion rod 24 away from the docking column 7; a spring 234 is fixedly connected between the sleeve 33 and the surface of the insertion rod 24; during operation, when the insertion rod 24 is inserted into the connecting seat, the sleeve 33 will be hindered by the connecting seat, causing it to move away from the direction toward the tip of the insertion rod 24 and compress the spring 234, so that the insertion rod 24 can be smoothly inserted into the docking seat 20. When the insertion rod 24 is pulled out from the docking seat 20, the compressed spring 234 recovers and drives the sleeve 33 to move toward the tip of the insertion rod 24, and finally the sleeve 33 covers the tip of the insertion rod 24, thereby preventing the user from accidentally bumping into it and causing accidental injury.

[0037] like Figure 5 As shown, the push plate 19 is provided with four evenly arranged extension plates 35 on the side surface away from the support seat 2; the push plate 19 surface is fixedly connected with baffles 36 on both sides of the extension plates 35; an extrusion rod 37 is threadedly connected to the surface of any one of the baffles 36, and the extrusion rod 37 passes 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 pair of baffles 36. To this end, the user needs to first screw the extrusion rod 37 so that it no longer squeezes the extension plate 35 between the pair of baffles 36, and then the user slides the extension plate 35 so that the extension plate 35 moves toward the center of the circle away from the push plate 19. After moving to a suitable position, the position of the extension plate 35 is fixed by screwing 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 push the PTFE pipe out of the interior of the pipe to be separated, thereby improving the scope of application of the embodiment of the present invention.

[0038] like Figure 5 As shown, an adjusting ring 38 is rotatably connected at the center of 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; one end of the adjusting rod 39 away 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 rotate the adjusting ring 38 on the surface of the push plate 19, and the adjusting ring 38 drives the adjusting rod 39 to deflect, thereby driving the adjusting rod 39 to push or pull the extension plate 35, thereby realizing synchronous adjustment of multiple extension plates 35, and when the user rotates one of the extrusion 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 the positions of the other extension plates 35 are also fixed together, so that the user only needs to fix any one extension plate 35 to achieve synchronous fixation of other extension plates 35, further improving the ease of use of the embodiment of the present invention.

[0039] like Figure 1 , Figure 2 and Figure 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 a servo motor; the surface of the driving roller 41 is fixedly connected with a plurality of uniformly arranged strip protrusions 42, and the strip protrusions 42 are made of rubber; during operation, when the pipeline to be separated is placed in the receiving groove 10, the support plate 9, driven by the hydraulic system, will drive the two driving seats 40 to rise, and make the driving rollers 41 on the top of the driving seats 40 and the strip protrusions 42 on the surface thereof contact with the pipeline to be separated, at this time, the servo motor drives the driving rollers 41 to rotate, so that the driving rollers 41 can be rotated, and the pipeline to be separated can be driven to rotate, and at the same time, the strip 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] like Figure 8 As shown, there is a gap between the two driving seats 40; a top plate 43 is slidably connected to the surface of the support plate 9 between the two driving seats 40, and the cross-section of the top of the top plate 43 is triangular; a guide plate 44 is fixedly connected to the top of the workbench 1 on one side of the inclined surface of the top of the top plate 43; during operation, when 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, and the pipe to be separated is pushed away from the rotating roller, and because the inclined surface of the top of the top plate 43 faces the guide plate 44, the pipe to be separated will rotate toward the guide plate 44, and under the guidance of the guide plate 44, the pipe to be separated will eventually roll out of the top surface of the workbench 1, thereby facilitating the user's unloading operation.

[0041] During operation, in order to avoid damaging the metal pipe on the outside of the waste PTFE pipe during the recycling process, the embodiment of the present invention can be used. Here, the pipe that has not yet completed the separation of the metal pipe and the PTFE pipe 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, and then the moving seat 3 on one side of the workbench 1 will be driven by the servo motor to move toward the support seat 2. During this process, the moving seat 3 will insert the connecting frame 4 into the interior of the pipe to be separated, and finally insert the docking column 7 at one end of the connecting frame 4 into the docking groove 8 on the surface of the support seat 2. Then the servo motor drives the rotating wheel 5 to rotate, and then drives the diamond rope 6 to rotate around the two rotating wheels 5. At this time, the driving component drives the pipe to be separated to rise again, so that the PTFE pipe serving as the lining contacts the diamond rope 6, and the two ends of the diamond rope 6 are consistent in height with the inner wall of the bottom of the metal pipe, so that the PTFE pipe is rubbed by the diamond rope 6, thereby realizing the cutting of the PTFE pipe. Since the diamond rope 6 has a diameter, the diamond rope 6 is used for rubbing the PTFE pipe. After cutting, an incision will be cut on the surface of the PTFE pipe, and the cut surfaces on both sides are not in a fit state. Since the two ends of the diamond rope 6 are at the same height as the inner wall of the bottom of the metal pipe, the bottom of the diamond rope 6 in the middle will stop after cutting the inner wall of the metal pipe, thereby avoiding damage to the metal pipe. Then the driving component drives the PTFE pipe away from the diamond rope 6, and then drives the pipe to be separated to rotate 180 degrees, and then repeats the previous cutting operation. At this time, the PTFE pipe in the pipe to be separated will be cut into two unconnected parts. At the same time, since there is an incision between the two cut parts of the PTFE, the diameter of the complete pipe assembled from the two parts is smaller than that of the PTFE pipe that has not been cut before. Therefore, the PTFE pipe can no longer be tightly attached to the inner wall of the pipe to be separated, so that the user can pull the PTFE pipe out of the metal pipe and recycle it separately, thereby avoiding damage to the metal pipe outside the PTFE pipe during the recycling process, thereby affecting the normal use of the external metal pipe.

[0042] When the driving assembly drives the pipe to be separated to rise, the tensioning wheel 12 at the end of the support arm 11 will be located outside the pipe to be separated, and the bottom of the tensioning wheel 12 is lower than the bottom of the pipe to be separated. Therefore, the tensioning wheels 12 at both ends can provide downward pulling force for the diamond rope 6, so that the diamond rope 6 can be tightly attached to the surface of the PTFE pipe, thereby improving the cutting efficiency of the PTFE pipe.

[0043] 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 that the supporting arm 11 is pulled by the traction plate 15, so that the supporting arm 11 slides along the annular groove 14 on the surface of the connecting plate 13, and then the tensioning wheel 12 is deflected toward the direction of the connecting frame 4, so that the tensioning plate is received in 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, and when both ends of the connecting frame 4 are After being located outside the pipe to be separated, the hydraulic rod 18 will drive the connecting rods 17 on both sides 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 cut the PTFE pipe normally. By rotating the support arm 11, the total height between the connecting frame 4 and the support arm 11 can be shortened, thereby facilitating the connecting frame 4 to pass through the PTFE pipe with a smaller diameter, thereby improving the scope of application 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 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 rope 6 completes the cutting of the PTFE pipe, 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 in the direction away from the support seat 2, so that the push plate 19 passes through the inside of the pipe to be separated, and then the cut inside the pipe to be separated is The PTFE pipe fragments are pushed out of the waste pipe, thereby further facilitating the user's recycling operation of the PTFE pipe fragments. After the user cleans up the waste pipe at the driving assembly, the movable seat 3 will drive the connecting frame 4 to move toward the supporting seat 2 again, and reinsert the docking seat 20 into the docking groove 8. At this time, the protrusion 21 on the surface of the supporting 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 supporting seat 2 through the cooperation of the protrusion 21 and the docking hole 22, thereby completing the resetting operation of the push plate 19.

[0045] When the insertion rod 24 is inserted into the docking seat 20 through the socket 23, the insertion rod 24 will pass through the socket 23 and the through hole 27 at the end of the metal cup 26, and contact the ball 29 at the accommodating groove 28. At this time, due to the friction force, the insertion rod 24 will drive the ball 29 and the metal cup 26 to move in the direction away from the socket 23. In this process, the metal cup 26 will compress the spring 1 31 through the connecting ring 30. When the insertion rod 24 is fully inserted into the metal cup 26, the spring 1 31 is reset to push the metal cup 26 toward the socket 23. At this time, the ball 29 will move toward the inside of the metal cup 26 under the pressure of the inner wall of the tapered cavity 25, thereby clamping the insertion rod 24 inside the metal cup 26. At this time, when the insertion rod 24 is pulled in the direction away from the spring 1 31, the insertion rod 24 will drive the ball 29 and the metal cup 26 to move toward the socket 23 due to the friction between the ball 29. At this time, The closer the inner wall of the tapered cavity 25 is to the through hole 27, the smaller the diameter is, so the squeezing force between the ball 29 and the rod 24 is greater, thereby locking the rod 24 and the docking seat 20 together. When the user needs to separate the 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, thereby sucking the metal cup 26 toward the push plate 19 and compressing the spring 1 31. At this time, the inner wall of the cylindrical cavity can no longer squeeze the ball 29, and the ball 29 will no longer squeeze the rod 24, so that the rod 24 can be separated from between the ball 29, and the rod 24 can be pulled out of the docking seat 20, thereby realizing the locking and unlocking between the rod 24 and the docking seat 20, and the user does not need to perform too much operation, thereby reducing the difficulty of use for the user and improving the ease of use of the embodiment of the present invention.

[0046] During the process of inserting the insertion rod 24 into the connecting seat, the sleeve 33 will be hindered by the connecting seat, causing it to move away from the direction toward the tip of the insertion rod 24 and compress the spring 2 34 so that the insertion rod 24 can be smoothly inserted into the docking seat 20. When the insertion rod 24 is pulled out from the docking seat 20, the compressed spring 2 34 recovers and drives the sleeve 33 to move toward the tip of the insertion rod 24, and finally the sleeve 33 covers the tip of the insertion rod 24, thereby preventing the user from accidentally bumping into it and causing accidental injury.

[0047] 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 pair of baffles 36. To this end, the user needs to first screw the extrusion rod 37 so that it no longer squeezes the extension plate 35 between the pair of baffles 36, and then the user slides the extension plate 35 so that the extension plate 35 moves toward the center of the circle away from the push plate 19. After moving to a suitable position, the position of the extension plate 35 is fixed by screwing the extrusion rod 37 on the surface of the baffle 36, so that the extension plate 35 can contact the PTFE pipe instead of the push plate 19, and then push the PTFE pipe out of the interior of the pipe to be separated, thereby improving the scope of application of the embodiment of the present invention.

[0048] When the user needs to move the extension plate 35, the user can rotate the adjustment ring 38 on the surface of the push plate 19, and the adjustment ring 38 drives the adjustment rod 39 to deflect, thereby driving the adjustment rod 39 to push or pull the extension plate 35, thereby realizing synchronous adjustment of multiple extension plates 35. When the user rotates one of the extrusion rods 37 to fix one of the extension plates 35, since the extension rod is connected to the adjustment ring 38 through the adjustment rod 39, the rotation of the adjustment ring 38 is also restricted, and the positions of the other extension plates 35 are also fixed together. Therefore, the user only needs to fix any one extension plate 35 to achieve 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 in the receiving groove 10, the support plate 9, driven by the hydraulic system, will drive the two driving seats 40 to rise, and make the driving roller 41 on the top of the driving seat 40 and the strip protrusion 42 on its surface contact with the pipe to be separated. At this time, the servo motor drives the driving roller 41 to rotate, so that the driving roller 41 can rotate and drive the pipe to be separated to rotate. At the same time, the strip protrusion 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] When 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 push the pipe 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 pipe to be separated will rotate toward the guide plate 44. Under the guidance of the guide plate 44, the pipe to be separated will eventually roll out of the top surface of the workbench 1, thereby facilitating the user's unloading operation.
