Description

Technical Field

[0001] The present invention relates to the technical field of steel fiber tape lined stainless steel composite pipes, and more specifically, to steel fiber tape lined stainless steel composite pipes, a composite forming production line and a working method thereof. Background Art

[0002] The lined stainless steel composite pipe is a pipe made of PE material and stainless steel. Stainless steel has good corrosion resistance and can effectively resist the erosion of water, chemicals, etc., ensuring the purity of water quality. At the same time, its inner wall is smooth and the fluid resistance is small, which is conducive to the transportation of fluid. The outer layer of PE material has good flexibility, impact resistance and low temperature resistance, can adapt to different geological conditions and environmental changes, and is not easily broken by external forces.

[0003] At present, in the existing composite pipe structure, in order to further improve the strength, technicians have innovatively embedded a layer of steel wire mesh or steel wire braided belt in the middle of the PE material. When the existing steel wire braided belt is wound, the steel belt is released by rotating the material tray, and then multiple material trays are tilted and rotated to complete the winding of the steel belt, and then it is processed by injection molding. After the processing is completed, the stainless steel pipe is inserted into the pipe.

[0004] However, although the composite steel wire mesh or steel wire braided belt achieves the purpose of improving the strength of the pipeline, there are still certain gaps in the steel wire mesh or braided belt, and the expected strength cannot be achieved. Moreover, the size of the material disc that carries the braided belt is fixed. If braided belts of different widths are used, the material discs are incompatible and need to be repeatedly disassembled and replaced. During winding, because the pipeline will be bent, the steel belt will warp during the winding process, reducing the strength of the pipeline after the composite braided belt is added. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a steel fiber tape lined stainless steel composite pipe, a composite forming production line and a working method thereof.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a stainless steel composite pipe lined with a steel fiber belt, including a pipeline structure, wherein the pipeline structure includes a PE inner pipe, the outer wall of the PE inner pipe is spirally wrapped with four steel fiber belts, and the four steel fiber belts are spliced ​​with each other, and the steel fiber belts are woven into belts with steel wires and then injection molded with PE material to form a strip material.

[0007] A PE outer tube is arranged outside the steel fiber belt, the PE inner tube and the PE outer tube are integrally formed, and a stainless steel tube is inserted into the interior of the PE inner tube.

[0008] By adopting the above technical solution, the steel fiber belt is a complete strip material without gaps. Not only is the strength increased by the internal steel wires, but the gaps between the steel wires are compensated by the external injection material, thereby further improving the strength of the pipeline.

[0011] Guide holes are provided on the side walls of the box body and the side walls of the support plate, and the guide holes correspond to the hole positions in the middle of the ring body. A conveying assembly is installed on the side of the box body away from the support plate, and the conveying assembly includes two groups of first electric rollers and two groups of second electric rollers installed on the side walls of the box body, and the two groups of the first electric rollers and the two groups of the second electric rollers are staggered.

[0012] A supporting assembly and an adjusting assembly are arranged on a side of the winding assembly away from the conveying assembly, and the adjusting assembly is located above the supporting assembly.

[0013] The present invention is further configured as follows: an auxiliary wheel is rotatably connected to the upper side of the support plate close to the ring body, a transmission belt is connected to the auxiliary wheel and the outer walls of two of the pulleys, the outer wall of the transmission belt is in contact with the outer wall of the ring body, a servo motor is installed on the side of the support plate away from the ring body, and the output end of the servo motor is connected to one of the pulleys driven by the transmission belt.

[0014] The present invention is further configured as follows: each group of the material tray mechanisms includes an assembly plate installed on the side wall of the ring body and an adjustment block rotatably connected to the side wall of the assembly plate, an adjusting rotary cylinder is installed on one side of the assembly plate, the adjusting rotary cylinder is connected to the adjustment block, a first tray body is installed on the side of the adjustment block away from the assembly plate, two auxiliary cylinders are symmetrically installed on the side wall of the first tray body, and the piston rods of the two auxiliary cylinders pass through the side wall of the first tray body and are connected to the second tray body.

[0015] The present invention is further configured as follows: the repair mechanism includes a mounting plate installed on the corresponding adjustment block on the side wall close to the center of the ring body, the mounting plate is rotatably connected to two auxiliary rollers on one side close to the first disk body, a through groove is provided on the side wall of the mounting plate, a connecting rod is hingedly connected inside the through groove, an adjusting cylinder is installed on the side of the mounting plate away from the auxiliary roller, the piston rod end of the adjusting cylinder is hinged to one end of the connecting rod, and a track is connected to the outer side wall of the connecting rod.

[0016] The present invention is further configured as follows: a repair rotating cylinder is installed on one side of the track, and the output end of the repair rotating cylinder is connected to a pressure plate, which is hinged to the inside of the track, and two wheel frames are symmetrically installed on the side of the pressure plate close to the track, and a hinge plate is hinged inside each of the wheel frames, one end of the hinge plate is rotatably connected to a pressure wheel, and the other end of the hinge plate is connected to a pressure rod, which passes through the wheel frame, and a spring is connected between the outer wall of the pressure rod and the side of the wheel frame away from the hinge plate, and the spring is sleeved on the outside of the pressure rod.

[0017] By adopting the above technical solution, the second disk is driven to separate from the first disk and the placement column by the auxiliary cylinder, and the spare steel fiber belt is directly put on the placement column through the gap between the second disk and the placement column, and the gap between the first disk and the second disk can be adjusted according to the different widths of the steel fiber belt, which greatly improves the functionality of the device.

[0018] After the steel fiber belt is released from between the first disk and the second disk, it first passes through the track and then fits onto the outer wall of the PE inner tube. If the steel fiber belt is warped, the adjusting cylinder pushes the connecting rod to swing, and the connecting rod drives the track to swing. The track pulls the steel fiber belt to adjust the fitting angle, so that the warped steel fiber belt is pulled back to its original position, alleviating the warping of the steel fiber belt.

[0019] By setting a pressure plate, the steel fiber belt passes through the inside of the track and under the pressure plate when released. When the steel fiber belt warps, the repair cylinder drives the pressure plate to swing, so that the pressure wheel fits the surface of the steel fiber belt. At the same time, the pressure wheel moves in the opposite direction to buffer the spring pressure, ensuring continuous squeezing rather than complete compression of the steel fiber belt, ensuring that the steel fiber belt can be continuously released while being squeezed. Then the cylinder is adjusted to push the connecting rod to swing, and the connecting rod drives the track and the pressure plate to swing. The steel fiber belt clamped by the pressure plate and the track is forcibly pulled, so that the steel fiber belt that has already warped is clamped and pulled to reset, avoiding the folding of the steel fiber belt caused by direct adjustment of the track.

[0020] The present invention is further configured as follows: the support assembly includes a fixed frame installed on the top of the base, a frame is installed on the top of the fixed frame, a limiting frame is hinged on the top of the frame, a gap is provided between the frame and the limiting frame, and an auxiliary mechanism is slidably connected to the top of the fixed frame, and the auxiliary mechanism is located between the frame and the winding assembly.

[0021] The present invention is further configured as follows: two guide rods are symmetrically installed on the top of the fixed frame, and a slider is slidably connected to the outer side wall of each guide rod, the auxiliary mechanism is installed on the top of the two sliders, and a driving cylinder is installed on the top of the fixed frame, and the piston rod end of the driving cylinder is connected to the bottom of the auxiliary mechanism, and the auxiliary mechanism includes an auxiliary tube installed on the top of the two sliders, the interior of the auxiliary tube is rotatably connected to a tube body, a driving motor is installed at the bottom of the auxiliary tube, a transmission mechanism is connected between the driving motor and the tube body, and three connecting plates are equidistantly installed on the inner wall of the tube body, a triangular plate is connected between the three connecting plates, and a tube hole is opened in the middle of the triangular plate.

[0022] The present invention is further configured as follows: the adjustment component includes two legs arranged on both sides of the fixed frame, guide rails are installed on the tops of the two legs, the side walls of the guide rails are slidably connected to an electric slide, the side walls of the electric slide are vertically installed with a lifting cylinder, and a U-shaped block is installed at the bottom of the lifting cylinder.

[0023] By adopting the above technical scheme, three auxiliary points are set on the PE inner tube before it enters the winding assembly through the cooperation of the frame, the auxiliary mechanism and the U-shaped block of the adjustment assembly. The frame is a fixed point support, and the auxiliary mechanism slides on the outer wall of the PE inner tube, so as to adjust the position of the auxiliary support to prevent the PE inner tube from sagging due to gravity. During the movement of the auxiliary mechanism, the U-shaped block is used to adjust the height at the fixed position of the PE inner tube to ensure that the PE inner tube remains horizontal before entering the auxiliary mechanism, which facilitates the auxiliary support of the auxiliary mechanism and avoids the PE inner tube being scratched when entering the triangle plate in a bent state. The adjusted PE inner tube can maintain horizontal spiral winding when entering the winding assembly to avoid the warping of the steel fiber belt due to the bending problem of the PE inner tube itself.

[0024] The steel fiber tape lined stainless steel composite pipe forming and compounding working method uses the steel fiber tape lined stainless steel composite pipe forming and compounding production line as described above, including the following steps: S1. First, the PE inner tube is injection molded through the PE tube one-time injection molding production line, and then the produced PE inner tube is sequentially passed through the support component, the adjustment component, the ring body and the guide hole opened on the side wall of the box body, and the outer wall of the PE inner tube is in contact with the two groups of first electric rollers and the second electric rollers. The two groups of first electric rollers and the two groups of second electric rollers cooperate to transport the PE inner tube horizontally. During the transportation process, the support component horizontally supports and guides the PE inner tube, and the adjustment component is used to limit and adjust the PE inner tube.

[0025] S2. After the PE inner tube passes through the support assembly, the outer wall of the PE inner tube is coated with glue using an external glue coating device. Then, the four sets of material tray mechanisms are driven to rotate by the ring body. Steel fiber belts are released from each set of material tray mechanisms. The steel fiber belts are first transported to the repair mechanism. The repair mechanism adjusts the offset position of the steel fiber belts in real time. After the adjustment is completed, the steel fiber belts are attached to the glue-coated position of the outer wall of the PE inner tube.

[0026] S3. When the steel fiber tape on the tray mechanism is used up, the tray mechanism is controlled to open, and the spare steel fiber tape can be directly placed on the tray mechanism, and the tray mechanism can be adjusted according to the different widths of the steel fiber tape. After placement, continue to use the tray mechanism to release the steel fiber tape for spiral winding and compounding. After the steel fiber tape and the PE inner tube are compounded, they are put into the PE secondary injection molding production line for secondary injection molding of the PE outer tube, so that the steel fiber tape is coated inside the PE outer tube. After the secondary injection molding is completed, use the set production line to insert the stainless steel tube into the steel fiber tape, and finally form a steel fiber tape lined with stainless steel composite tube.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: (1) By setting up a steel fiber belt, which is a complete strip material without gaps, the strength of the pipeline is not only increased by the internal steel wires, but also the gaps between the steel wires are compensated by the external injection molding material, thereby further improving the strength of the pipeline.

[0028] (2) By setting up the first disk and the second disk, the second disk is driven by the auxiliary cylinder to separate from the first disk and the placement column, and the spare steel fiber belt is directly put on the placement column through the gap between the second disk and the placement column, and the gap between the first disk and the second disk can be adjusted according to the different widths of the steel fiber belt, which greatly improves the functionality of the device.

[0029] (3) Through the cooperation of the frame, auxiliary mechanism and U-shaped block of the adjustment component, three auxiliary points are set on the PE inner tube before it enters the winding component. The frame is a fixed point support, and the auxiliary mechanism slides on the outer wall of the PE inner tube, thereby adjusting the position of the auxiliary support to prevent the PE inner tube from sagging due to gravity. During the movement of the auxiliary mechanism, the U-shaped block is used to adjust the height of the fixed position of the PE inner tube to ensure that the PE inner tube remains horizontal before entering the auxiliary mechanism, which is convenient for the auxiliary support of the auxiliary mechanism and avoids the PE inner tube from being scratched when entering the triangle plate in a bent state. The adjusted PE inner tube can maintain horizontal spiral winding when entering the winding component to avoid the warping of the steel fiber belt due to the bending problem of the PE inner tube itself.

[0030] (4) By setting up a track, the steel fiber belt first passes through the track after being released from between the first disk and the second disk, and then adheres to the outer wall of the PE inner tube. If the steel fiber belt is warped, the adjusting cylinder pushes the connecting rod to swing, and the connecting rod drives the track to swing. The track pulls the steel fiber belt to adjust the fitting angle, so that the steel fiber belt that has already warped is pulled back to its original position, thereby alleviating the warping of the steel fiber belt.

[0031] (5) By setting a pressure plate, the steel fiber belt passes through the inside of the track and under the pressure plate when it is released. When the steel fiber belt is warped, the repair cylinder drives the pressure plate to swing so that the pressure wheel fits the surface of the steel fiber belt. At the same time, the pressure wheel moves in the opposite direction to buffer the spring pressure, ensuring continuous squeezing rather than complete compression of the steel fiber belt, ensuring that the steel fiber belt can be continuously released while being squeezed. Then the cylinder is adjusted to push the connecting rod to swing, and the connecting rod drives the track and the pressure plate to swing. The steel fiber belt clamped by the pressure plate and the track is forcibly pulled, and then the steel fiber belt that has already warped is clamped and pulled back to its original position, avoiding the situation where the steel fiber belt is folded by direct adjustment of the track.

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0048] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0049] See also Figure 1-Figure 14 , the present invention provides the following technical solutions: Example 1, see Fig.13The steel fiber belt lined stainless steel composite pipe includes a pipeline structure 6, which includes a PE inner tube 61. The outer wall of the PE inner tube 61 is spirally wrapped with four steel fiber belts 62, and the four steel fiber belts 62 are spliced ​​with each other. The steel fiber belts 62 are woven into belts with steel wires and then injection molded with PE materials to form a belt-shaped material. A PE outer tube 63 is arranged on the outside of the steel fiber belt 62. The PE inner tube 61 and the PE outer tube 63 are integrally formed, and a stainless steel tube 64 is inserted into the inside of the PE inner tube 61.

[0050] Compared with the existing lining of steel wire braided mesh or steel wire braided belt, the steel fiber belt 62 is a complete belt material without gaps. It not only increases the strength through the internal steel wires, but also uses the external injection material to compensate for the gaps between the steel wires, thereby further improving the strength of the pipeline.

[0051] See also Figure 1 and Fig.14 The steel fiber belt lined stainless steel composite pipe molding composite production line includes a base 1, a winding component 2 installed on the top of the base 1, a PE pipe primary injection molding production line, a PE pipe secondary injection molding production line and a set production line. The winding component 2 is located between the PE pipe primary injection molding production line and the PE pipe secondary injection molding production line.

[0052] First, the PE inner tube 61 is injection molded through the PE pipe primary injection molding production line, and then the produced PE inner tube 61 is wrapped with the steel fiber tape 62 using the winding component 2. After the steel fiber tape 62 and the PE inner tube 61 are composited, they are put into the PE secondary injection molding production line for secondary injection molding of the PE outer tube 63, so that the steel fiber tape 62 is coated inside the PE outer tube 63. After the secondary injection molding is completed, the stainless steel tube 64 is inserted into the steel fiber tape 62 using the set production line, and finally a steel fiber tape lined stainless steel composite tube is formed.

[0053] See also Figure 1 and Figure 6 The specific structure of the winding component 2 is as follows: The winding assembly 2 includes a box body 21 installed on the top of the base 1 and a support plate 22 arranged on one side of the box body 21, a side of the support plate 22 away from the box body 21 is rotatably connected with a ring body 23 and a plurality of pulleys 25, the ring body 23 is located between the plurality of pulleys 25, and the ring body 23 is respectively meshed with the plurality of pulleys 25, an auxiliary wheel 27 is rotatably connected to the upper side of the support plate 22 close to the ring body 23, the auxiliary wheel 27 is connected to the outer walls of two of the pulleys 25 for transmission, the outer wall of the transmission belt 28 is in contact with the outer wall of the ring body 23, a servo motor 26 is installed on the side of the support plate 22 away from the ring body 23, the output end of the servo motor 26 is connected to one of the pulleys 25 driven by the transmission belt 28, guide holes are opened on the side walls of the box body 21 and the side walls of the support plate 22, the guide holes correspond to the hole positions in the middle of the ring body 23, and four groups of material tray mechanisms 24 are equidistantly installed around the side of the ring body 23 away from the support plate 22.

[0054] The produced PE inner tube 61 passes through the ring body 23 and the guide hole in turn, and the servo motor 26 is used to drive the corresponding pulley 25 to rotate. Since the transmission belt 28 is supported by the auxiliary wheel 27 and multiple pulleys 25, when one of the pulleys 25 rotates, the transmission belt 28 is driven to transmit. The transmission belt 28 drives the ring body 23 to rotate through friction. When the ring body 23 rotates, it drives the four sets of material tray mechanisms 24 to move around, and a rolled steel fiber belt 62 is placed on the material tray mechanism 24. The material tray mechanism 24 releases the steel fiber belt 62 and wraps it around the outer wall of the PE inner tube 61.

[0055] See also Figure 7 A conveying assembly 3 is installed on the side of the box body 21 away from the support plate 22. When the PE inner tube 61 is wrapped around the steel fiber belt 62, the conveying assembly 3 continuously conveys the PE inner tube 61, thereby achieving the purpose of continuously wrapping the steel fiber belt 62.

[0056] See also Figure 7 The conveying assembly 3 includes two groups of first electric rollers 31 and two groups of second electric rollers 32 installed on the side walls of the box body 21. The two groups of first electric rollers 31 and the two groups of second electric rollers 32 are staggered. The PE inner tube 61 passes through the ring body 23 and the guide hole and extends to the staggered position of the two groups of first electric rollers 31 and the two groups of second electric rollers 32. The two groups of first electric rollers 31 and the two groups of second electric rollers 32 are started, and the rotation directions of the two groups of first electric rollers 31 are opposite, and the rotation directions of the two groups of second electric rollers 32 are opposite. The PE inner tube 61 is conveyed forward by the two groups of first electric rollers 31 and the two groups of second electric rollers 32. During the conveying process, the tray mechanism 24 continuously releases the steel fiber belt 62, thereby completing the continuous winding of the steel fiber belt 62.

[0057] See also Figure 8 and Fig. 9Each set of tray mechanisms 24 includes a mounting plate 241 mounted on the side wall of the ring body 23 and an adjusting block 242 rotatably connected to the side wall of the mounting plate 241. An adjusting rotary cylinder is mounted on one side of the mounting plate 241. The adjusting rotary cylinder is connected to the adjusting block 242. A first tray 243 is mounted on the side of the adjusting block 242 away from the mounting plate 241. A second tray 244 is arranged on one side of the first tray 243. The adjusting rotary cylinder is used to drive the adjusting block 242, the first tray 243 and the second tray 244. 44 swings, and then adjusts the release angle of the steel fiber belt 62, that is, when the steel fiber belt 62 is wound, the first disk body 243 and the second disk body 244 are in an inclined state, so that the steel fiber belt 62 can be spirally wound on the outer wall of the PE inner tube 61, and the four sets of material tray mechanisms 24 cooperate to achieve the purpose of uniform winding and compounding. After the compounding is completed, the PE outer tube 63 is secondary injection molded through the PE secondary injection molding production line, and then the stainless steel pipe 64 is inserted into the interior of the steel fiber belt 62 by using the set production line, finally forming a steel fiber belt lined with stainless steel composite pipe.

[0058] In the second embodiment, the size of the existing material tray that carries the braided belt is fixed. If braided belts of different widths are used, the material trays are not compatible and need to be repeatedly disassembled and replaced. When winding, the pipe will bend and the edge of the steel belt will warp during the winding process, reducing the strength of the pipe after the composite braided belt is added.

[0059] To this end, two auxiliary cylinders 245 are symmetrically installed on the side wall of the first tray 243, and the piston rods of the two auxiliary cylinders 245 pass through the side wall of the first tray 243 and are connected to the second tray 244. When the steel fiber belt 62 on the tray mechanism 24 is used up, the second tray 244 is driven by the auxiliary cylinder 245 to separate from the first tray 243 and the placement column on the first tray 243, and the spare steel fiber belt 62 is directly put on the placement column through the gap between the second tray 244 and the placement column, and the gap between the first tray 243 and the second tray 244 can be adjusted according to the different widths of the steel fiber belt 62, which greatly improves the functionality of the device.

[0060] If the steel fiber belt 62 of different width is replaced, it is only necessary to use the adjusting rotary cylinder to drive the adjusting block 242, the first plate 243 and the second plate 244 to swing, so that the replaced steel fiber belt 62 can adapt to the angle and position of the spiral winding. In addition, in the winding process, once the steel fiber belt 62 warps, the subsequent warping can be prevented by adjusting the winding angle and position of the steel fiber belt 62.

[0061] In order to solve the problem that the PE inner tube 61 itself has a slight bend due to its length and the center of gravity, the steel fiber belt 62 may still warp on the outside of the PE inner tube 61, a support component 4 and an adjustment component 5 are provided on the side of the winding component 2 away from the conveying component 3, and the adjustment component 5 is located above the support component 4. Before the PE inner tube 61 is conveyed to the position of the winding component 2, the support component 4 horizontally supports and guides the PE inner tube 61, and the adjustment component 5 is used to limit the PE inner tube 61. The specific structure of the support component 4 is as follows: See also Figure 1-Figure 3 The support assembly 4 includes a fixing frame 41 installed on the top of the base 1, a frame 45 is installed on the top of the fixing frame 41, a limiting frame 46 is hinged on the top of the frame 45, and a gap is set between the frame 45 and the limiting frame 46. When the PE inner tube 61 is transported, it is first placed on the top of the frame 45, so that the PE inner tube 61 is auxiliary supported before entering the winding assembly 2, and the limiting frame 46 is swung to press on the top of the PE inner tube 61 and the frame 45, thereby limiting the PE inner tube 61.

[0062] See also Figure 1-Figure 3 The top of the fixed frame 41 is slidably connected with an auxiliary mechanism 47, which is located between the frame 45 and the winding assembly 2. The auxiliary mechanism 47 is used to perform auxiliary adjustments between the frame 45 and the winding assembly 2 to ensure that the PE inner tube 61 remains in a horizontal state before entering the winding assembly 2.

[0063] See also Figure 1-Figure 3 In this embodiment, two guide rods 42 are symmetrically installed on the top of the fixed frame 41, and a slider 43 is slidably connected to the outer wall of each guide rod 42. The auxiliary mechanism 47 is installed on the top of the two sliders 43. A driving cylinder 44 is installed on the top of the fixed frame 41. The piston rod end of the driving cylinder 44 is connected to the bottom of the auxiliary mechanism 47. The driving cylinder 44 is used to push the auxiliary mechanism 47 to slide above the fixed frame 41, and the auxiliary mechanism 47 is limited by the slider 43 and the guide rod 42. Through the movement of the auxiliary mechanism 47, the auxiliary mechanism 47 can be adjusted to assist in adjusting the position of the PE inner tube 61.

[0064] See also Figure 1-Figure 3The auxiliary mechanism 47 includes an auxiliary cylinder 471 installed on the top of the two sliders 43, the auxiliary cylinder 471 is rotatably connected to the tube body 474, a driving motor 472 is installed at the bottom of the auxiliary cylinder 471, a transmission mechanism 473 is connected between the driving motor 472 and the tube body 474, three connecting plates 475 are equidistantly installed on the inner wall of the tube body 474, a triangular plate 476 is connected between the three connecting plates 475, a tube hole is opened in the middle of the triangular plate 476, and the PE inner tube 61 passes through the tube hole in the middle of the triangular plate 476. When the auxiliary mechanism 47 moves as a whole, the triangular plate 476 76 slides on the outer wall of the PE inner tube 61 to adjust the supporting position of the PE inner tube 61, ensuring that the PE inner tube 61 is in a horizontal state when it passes through the triangular plate 476 and reaches the position of the ring body 23, and when the triangular plate 476 adjusts the PE inner tube 61, the driving motor 472 drives the tube body 474 to rotate through the transmission mechanism 473, and the tube body 474 drives the connecting plate 475 to move and drives the triangular plate 476 to rotate, so that the triangular plate 476 rotates on the outer wall of the PE inner tube 61 to prevent the triangular plate 476 from directly sliding horizontally and causing the PE inner tube 61 to be scratched.

[0065] See also Figure 4 and Figure 5 The adjustment component 5 includes two legs 51 arranged on both sides of the fixed frame 41, and guide rails 52 are installed on the top of the two legs 51. The side walls of the guide rails 52 are slidably connected to the electric slide 53. The side walls of the electric slide 53 are vertically installed with lifting cylinders 54, and the bottom of the lifting cylinders 54 is installed with U-shaped blocks 55. Before the PE inner tube 61 passes through the frame 45 and does not reach the triangular plate 476, the lifting cylinder 54 is used to drive the U-shaped block 55 to move up and down, and the U-shaped block 55 is adjusted to a position with the same height as the PE inner tube 61. Then the electric slide 53 slides on the side walls of the guide rails 52, and then the U-shaped block 55 is stuck on the outer wall of the PE inner tube 61, so that the PE inner tube 61 is assisted by the U-shaped block 55 before it reaches the triangular plate 476, so as to prevent the PE inner tube 61 from entering the triangular plate 476 in a bent state and being scratched.

[0066] Specifically, through the cooperation of the frame 45, the auxiliary mechanism 47 and the U-shaped block 55 of the adjustment component 5, three auxiliary points are set on the PE inner tube 61 before entering the winding component 2. The frame 45 is a fixed point support, and the auxiliary mechanism 47 slides on the outer wall of the PE inner tube 61, so as to adjust the position of the auxiliary support to prevent the PE inner tube 61 from sagging due to gravity. During the movement of the auxiliary mechanism 47, the U-shaped block 55 is used to adjust the height of the fixed position of the PE inner tube 61 to ensure that the PE inner tube 61 remains horizontal before entering the auxiliary mechanism 47, so as to facilitate the auxiliary support of the auxiliary mechanism 47 and prevent the PE inner tube 61 from being scratched when entering the triangle plate 476 in a bent state. The adjusted PE inner tube 61 can maintain horizontal spiral winding when entering the winding component 2 to prevent the steel fiber belt 62 from warping due to the bending problem of the PE inner tube 61 itself.

[0067] In the third embodiment, even if the fitting angle and the release angle of the steel fiber belt 62 are adjusted so that the steel fiber belt 62 does not warp on the outside of the PE inner tube 61, once warping occurs, the above method can only prevent the warping problem at the position that has not been fitted, but cannot handle the situation where the warping has already occurred.

[0068] For this purpose, a repair mechanism 29 is installed on each set of material tray mechanisms 24. Before the steel fiber belt 62 is wound onto the outer wall of the PE inner tube 61, it is first transported to the repair mechanism 29. The repair mechanism 29 adjusts the offset position of the steel fiber belt 62 in real time. After the adjustment is completed, the steel fiber belt 62 is attached to the position where the outer wall of the PE inner tube 61 has been glued. The specific structure of the repair mechanism 29 is as follows: See also Figure 9-11 The repair mechanism 29 includes a mounting plate 291 mounted on the side wall of the corresponding adjustment block 242 close to the center of the ring body 23. The mounting plate 291 is rotatably connected to two auxiliary rollers 246 on one side close to the first plate 243. A through slot 294 is provided on the side wall of the mounting plate 291. A connecting rod 293 is hingedly connected inside the through slot 294. An adjusting cylinder 292 is installed on the side of the mounting plate 291 away from the auxiliary roller 246. The piston rod end of the adjusting cylinder 292 is hingedly connected to one end of the connecting rod 293. A track 295 is connected to the outer wall of the connecting rod 293. After the steel fiber belt 62 is released from between the first disk body 243 and the second disk body 244, it first passes through the track 295 and then adheres to the outer wall of the PE inner tube 61. If the steel fiber belt 62 is warped, the adjusting cylinder 292 pushes the connecting rod 293 to swing, and the connecting rod 293 drives the track 295 to swing. The track 295 pulls the steel fiber belt 62 to adjust the fitting angle, so that the steel fiber belt 62 that has already warped is pulled back to its original position.

[0069] See also Figure 9-11In this embodiment, a repair rotary cylinder 296 is installed on one side of the track 295, and a pressure plate 297 is connected to the output end of the repair rotary cylinder 296. The pressure plate 297 is hinged to the inside of the track 295. Two wheel frames 299 are symmetrically installed on the side of the pressure plate 297 close to the track 295. A hinge plate 2901 is hinged inside each wheel frame 299. One end of the hinge plate 2901 is rotatably connected to a pressure wheel 298, and the other end of the hinge plate 2901 is connected to a pressure rod, which penetrates the wheel frame 29 9, a spring 2902 is connected between the outer wall of the pressure rod and the side of the wheel frame 299 away from the hinge plate 2901, and the spring 2902 is sleeved on the outside of the pressure rod. When the steel fiber belt 62 is released, it not only passes through the inside of the track 295, but also passes under the pressure plate 297. Before the track 295 is swung and adjusted, the pressure plate 297 is quickly driven to swing by the repair rotating cylinder 296, so that the pressure plate 297 is close to the direction of the track 295, and the two pressure wheels 298 are attached to the steel fiber belt inside the track 295. 62 surface, at this time, the pressure wheel 298 moves in the opposite direction to the direction close to the pressure plate 297, and the pressure wheel 298 drives one end of the hinge plate 2901 to move synchronously, and the other end of the hinge plate 2901 pulls the pressure rod down, at this time the spring 2902 is squeezed, at this time the pressure wheel 298 is buffered, and the pressure wheel 298 can continue to squeeze the steel fiber belt 62 instead of completely tightening it, ensuring that the steel fiber belt 62 can be continuously released while being squeezed, and then the cylinder 292 is adjusted to push the connecting rod 293 to swing, and the connecting rod 2 93 drives the track 295 and the pressure plate 297 to swing, and the steel fiber belt 62 clamped by the pressure plate 297 and the track 295 is forcibly pulled, so that the steel fiber belt 62 that has already warped is clamped and pulled to reset, avoiding the situation where the steel fiber belt 62 is folded by direct adjustment of the track 295. After the reset is completed, the pressure plate 297 is separated from the track 295, the angle of the pressure plate 297 and the track 295 is reset, and the rotation speed of the ring body 23 returns to normal, and the work of spirally encircling the composite steel fiber belt 62 continues.

[0070] Embodiment 4, a method for forming and compounding a steel fiber tape lined stainless steel composite pipe, using the above steel fiber tape lined stainless steel composite pipe forming and compounding production line, comprises the following steps: S1. First, the PE inner tube 61 is injection molded through the PE tube one-time injection molding production line, and then the produced PE inner tube 61 is sequentially passed through the support component 4, the adjustment component 5, the ring body 23 and the guide hole opened on the side wall of the box body 21, and the outer wall of the PE inner tube 61 is in contact with the two groups of first electric rollers 31 and the second electric rollers 32. The two groups of first electric rollers 31 and the two groups of second electric rollers 32 cooperate to horizontally transport the PE inner tube 61. During the transportation process, the support component 4 horizontally supports and guides the PE inner tube 61, and the adjustment component 5 is used to limit and adjust the PE inner tube 61.

[0071] The more specific steps of S1 are: S11. Place the PE inner tube 61 on the top of the frame 45, and limit the PE inner tube 61 by the limiting frame 46. The PE inner tube 61 passes through the tube hole in the middle of the triangular plate 476, and then passes through the guide holes opened in the side walls of the ring body 23 and the box body 21, and the outer wall of the PE inner tube 61 fits with the two groups of first electric rollers 31 and the second electric rollers 32. The two groups of first electric rollers 31 and the two groups of second electric rollers 32 cooperate to transport the PE inner tube 61 horizontally.

[0072] S12. During the transportation process, the PE inner tube 61 is auxiliary supported and guided by the frame 45 and the limit frame 46, and the driving cylinder 44 is used to push the auxiliary mechanism 47 to move horizontally. The triangular plate 476 slides on the outer wall of the PE inner tube 61 to adjust the supporting position of the PE inner tube 61 to ensure that the PE inner tube 61 is in a horizontal state when it passes through the triangular plate 476 and reaches the position of the ring body 23. When the triangular plate 476 adjusts the PE inner tube 61, the driving motor 472 is used to drive the tube body 474 to rotate through the transmission mechanism 473. The tube body 474 drives the connecting plate 475 to move and drives the triangular plate 476 to rotate, so that the triangular plate 476 rotates on the outer wall of the PE inner tube 61 to prevent the triangular plate 476 from directly sliding horizontally and scratching the PE inner tube 61.

[0073] S13, before the PE inner tube 61 passes through the frame 45 and reaches the triangular plate 476, the lifting cylinder 54 is used to drive the U-shaped block 55 to move up and down, and the U-shaped block 55 is adjusted to a position with the same height as the PE inner tube 61. Then the electric slide 53 slides on the side wall of the guide rail 52, and then the U-shaped block 55 is clamped on the outer wall of the PE inner tube 61, so that the PE inner tube 61 is assisted by the U-shaped block 55 before it reaches the triangular plate 476, so as to prevent the PE inner tube 61 from entering the triangular plate 476 in a bent state and being scratched.

[0074] S2. After the PE inner tube 61 passes through the support assembly 4, the outer wall of the PE inner tube 61 is coated with glue using an external glue coating device, and then the four groups of material tray mechanisms 24 are driven to rotate through the ring body 23. The steel fiber belt 62 is released from each group of material tray mechanisms 24. The steel fiber belt 62 is first transported to the repair mechanism 29. The repair mechanism 29 adjusts the offset position of the steel fiber belt 62 in real time. After the adjustment is completed, the steel fiber belt 62 is attached to the position where the outer wall of the PE inner tube 61 has been coated with glue.

[0075] The more specific steps of S2 are: S21, after the PE inner tube 61 passes through the triangular plate 476, the outer wall of the PE inner tube 61 is coated with glue using an external gluing device. The steel fiber belt 62 first passes through two auxiliary rollers 246 for conveying and guiding, and then passes between the pressing plate 297 and the track 295, and finally sticks to the outer wall of the PE inner tube 61. The four groups of material tray mechanisms 24 are driven to rotate through the ring body 23, and the steel fiber belt 62 on each group of material tray mechanisms 24 is pulled and released to complete the bonding.

[0076] S22. During the bonding process, in order to achieve the purpose of bonding the four steel fiber bands 62 at the same time, the release direction of the steel fiber bands 62 is adjusted to an inclined direction, and the four steel fiber bands 62 are spirally wrapped and bonded.

[0077] S23. If one of the steel fiber bands 62 is warped during bonding, the overall rotation speed of the ring body 23 is controlled to slow down, and the corresponding adjustment block 242 is driven to swing by the corresponding adjustment rotating cylinder. The adjustment block 242 drives the corresponding first disk body 243 and the second disk body 244 to swing, and then the release direction of the corresponding steel fiber band 62 is adjusted to stop the continued occurrence of warping.

[0078] S24. Since the steel fiber belt 62 first passes between the pressure plate 297 and the track 295 when it is released, the pressure plate 297 is quickly driven to swing by the repair rotating cylinder 296, so that the pressure plate 297 approaches the track 295, and the two pressure wheels 298 are attached to the surface of the steel fiber belt 62 inside the track 295, ensuring that the steel fiber belt 62 can be continuously released while being squeezed. Then the adjustment cylinder 292 pushes the connecting rod 293 to swing, and the connecting rod 293 drives the track 295 and the pressure plate 297 to swing. The steel fiber belt 62 clamped by the pressure plate 297 and the track 295 is forcibly pulled, and then the steel fiber belt 62 that has warped edges is pulled and reset. After the reset is completed, the pressure plate 297 is separated from the track 295, the angle of the pressure plate 297 and the track 295 is reset, and the rotation speed of the ring body 23 returns to normal, and the work of spirally wrapping the composite steel fiber belt 62 continues.

[0079] S3. When the steel fiber tape 62 on the tray mechanism 24 is used up, the tray mechanism 24 is controlled to open, and the spare steel fiber tape 62 can be directly placed on the tray mechanism 24, and the tray mechanism 24 can be adjusted according to the different widths of the steel fiber tape 62. After placement, continue to use the tray mechanism 24 to release the steel fiber tape 62 for spiral winding and compounding. After the steel fiber tape 62 and the PE inner tube 61 are compounded, they are put into the PE secondary injection molding production line for secondary injection molding of the PE outer tube 63, so that the steel fiber tape 62 is coated inside the PE outer tube 63. After the secondary injection molding is completed, the stainless steel tube 64 is inserted into the interior of the steel fiber tape 62 using the set production line, and finally a steel fiber tape lined with stainless steel composite tube is formed.

[0080] The more specific steps of S3 are: S31. When the steel fiber belt 62 on the tray mechanism 24 is used up, the auxiliary cylinder 245 is used to drive the second tray body 244 to separate from the first tray body 243 and the placement column on the first tray body 243, and the spare steel fiber belt 62 is directly sleeved onto the placement column through the gap between the second tray body 244 and the placement column, and the gap between the first tray body 243 and the second tray body 244 can be adjusted according to the different widths of the steel fiber belt 62. After placement is completed, the tray mechanism 24 is continued to be used to release the steel fiber belt 62 for spiral winding and compounding.

[0081] After S32, the steel fiber belt 62 and the PE inner tube 61 are composited, they are put into the PE secondary injection molding production line for secondary injection molding of the PE outer tube 63, so that the steel fiber belt 62 is covered inside the PE outer tube 63. After the secondary injection molding is completed, the stainless steel tube 64 is inserted into the interior of the steel fiber belt 62 using the set production line, and finally a steel fiber belt lined stainless steel composite tube is formed.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
