Description

Technical Field

[0001] The invention relates to the technical field of composite pipe forming, in particular to a steel wire mesh reinforced polyethylene composite pipe forming production machine. Background Art

[0002] Wire mesh reinforced polyethylene composite pipes generally include an inner layer, a middle layer and an outer layer, wherein the inner layer is composed of high-density polyethylene, the middle layer is composed of a wire mesh skeleton and a bonding resin layer, and the outer layer is usually also made of high-density polyethylene.

[0003] When producing polyethylene composite pipes, an extruder, a wire winding machine and a traction machine are generally used to complete the pipe forming extrusion process.

[0004] After searching, a composite pipe forming device is disclosed in the patent document with patent application number CN202020420822.6. Its main structure includes a supporting base plate, a steel wire winding device, a composite pipe moving device and a water-cooled injection molding device. The steel wire winding device is arranged between the composite pipe moving device and the water-cooled injection molding device. The rotating shaft is hinged on the steel wire roller bracket, and the steel wire winding roller is arranged on the rotating shaft.

[0005] It can be seen from its working process that the steel on the steel wire winding roller is pulled out and fixed on the composite tube forming roller, and then the rotating motor and the displacement stretching rod are turned on at the same time. The rotating motor drives the composite tube forming roller to rotate, and the displacement stretching rod drives the sliding block to move in the sliding groove on the sliding support block. During the movement and rotation process, the steel wire is obliquely wound on the composite tube forming roller, and during the injection molding process, it is cooled by water injection through the cooling pipe so that the cooling pipe can be formed faster.

[0006] The above-mentioned forming device relies on the fixed-axis rotation of the steel wire winding roller and the rotating shaft to release the rope and wind it on the outer wall of the composite pipe forming roller before forming the composite pipe, waiting for injection molding in two semicircular injection molding grooves to realize the integration of the steel wire winding and the injection-molded pipe. However, this steel wire molding method is not applicable to the production of steel wire mesh reinforced polyethylene composite pipes. The main reasons are as follows: When producing wire mesh reinforced polyethylene composite pipes, it is generally necessary to first extrude the inner layer pipe and then wrap the steel wire around the outer layer of the inner layer pipe. This type of pipe cannot be formed by winding the steel wire using the above-mentioned forming device.

[0007] The above-mentioned wire winding method only relies on the fixed-axis rotation of the wire winding roller and the rotating shaft to achieve winding. The effect of the wire winding cannot be controlled, and the winding angle and tightness of the wire cannot be ensured, resulting in uneven strength of various parts of the pipe after subsequent pipe forming, affecting the quality of the pipe.

[0008] Based on this, the present invention optimizes the design for the problems existing in the composite molding production process of wire mesh reinforced polyethylene composite pipes in the prior art, and hereby proposes a wire mesh reinforced polyethylene composite pipe molding production machine to better solve the problems existing in the prior art.

[0014] Among them, the circumferential cooperation of the multiple arc-shaped silicone restraining seats can play a role in circumferential restraint and guidance for the inner layer tube, thereby preventing the inner layer tube from circumferential side swing and shaking.

[0015] The inner arc surface of the arc-shaped silicone restraining seat is spaced 0.2 mm to 0.3 mm from the surface of the inner tube passing through the center of the positioning annular tube.

[0019] When the steel wire composite forming device is working, the driving control mechanism is started to operate. When the driving control mechanism is operating, the main driving motor drives the main driving pinion to operate. When the main driving pinion operates, it can drive the large gear ring fixed axis that is meshed with it and is in the fixed axis limit state to rotate. When the large gear ring fixed axis rotates, it can cooperate with the internal fixed center gear and center guide gear tube to drive the various planetary gears and planetary gear shafts to revolve, and realize self-rotation while revolving. When the planetary gear shaft revolves, it will revolve around the center gear and the center guide gear tube, and the inner layer tube passing through the center guide gear tube is coaxial with it. Therefore, the planetary gear shaft will also revolve around the inner layer tube in the state of conveying to the right downstream, so that the rope drum fixedly connected to the right end of the planetary gear shaft with a longer length will revolve around the inner layer tube to realize winding the steel wire on the inner layer tube; during the winding process, the self-rotation of the long planetary gear shaft will drive the rope drum to rotate, thereby realizing the steel wire release, ensuring the smoothness of the steel wire winding, and controlling the steel wire release speed to be consistent with the winding speed of the steel wire on the inner layer tube.

[0020] Rope end covers are formed on both sides of the rope drum, and a quick rope tightening and bonding device is installed on the right side of the left rope end cover. The quick rope tightening and bonding device is used to pull and press the steel wire end just wound on the surface of the inner tube toward the soft surface of the inner tube and make the steel wire be crimped and bonded to the inner tube after an indentation groove is pressed on the surface of the inner tube.

[0022] The main function of the fast rope tightening and pressing device set here is to improve the instantaneous tension and compression of the steel wire when it is wound on the surface of the inner tube, so that the steel wire can be quickly pressed into the surface of the inner tube under high temperature, and then achieve better adhesion with the steel wire in this part during the continuous cooling of the inner tube, thereby ensuring the effect of subsequent steel wire winding and avoiding the probability of loose steel wire when the subsequent product is bent and used. Reasonable control of the speed of the counter-rotating motor can control the amplitude of the downward tension and compression of the steel wire.

[0023] In any of the above schemes, preferably, the inner layer tube cooling unit includes a fixed cooling pool, a cooling hood for the inner layer tube to pass through is installed above the cooling pool, and a plurality of cooling nozzles are installed at intervals on the top of the internal space of the cooling hood, each of the cooling nozzles is used to spray cooling liquid onto the upper surface of the inner layer tube, and each of the cooling nozzles is connected to the water outlet at the bottom of the cooling pool through a pump pipeline, and the sprayed cooling liquid falls back into the cooling pool.

[0025] When each of the self-rotating front rollers drives the high temperature resistant friction belt to rotate, it can cooperate with the external traction force and rely on the friction force of the high temperature resistant friction belt to drive the inner layer pipe to move downstream. At the same time, its main function is to support the inner layer pipe.

[0026] In any of the above schemes, it is preferred that the rear supporting mechanism includes a plurality of rear drive rollers rotating on a fixed axis, the top of each rear drive roller abuts against the bottom surface of the inner layer tube and the bottom of each spirally wound steel wire, and each rear drive roller is individually configured with a drive member.

[0027] When each rear drive roller rotates, it can cooperate with the external traction force and rely on the friction force to drive the inner layer pipe to move downstream. At the same time, its main function is to support the inner layer pipe.

[0028] In any of the above solutions, it is preferred that the drying equipment adopts a pipeline drying drum.

[0029] Compared with the prior art, the present invention has the following beneficial effects: 1. Optimize the production process and improve production efficiency: The patented wire mesh reinforced polyethylene composite pipe forming machine is installed between the inner layer pipe forming machine and the outer layer pipe forming machine, making the production process more compact and reasonable. The pipe transportation link is reduced, and the inner layer pipe can be directly transported to the outer layer pipe forming machine for outer pipe laying after being processed by wire winding, which effectively improves production efficiency and reduces production costs.

[0030] 2. The protection support and restraint mechanism is highly versatile and easy to operate: The protection support and restraint mechanism includes two interval-set pipe protectors. According to the outer diameter of the inner layer pipe, the air pressure linkage restraint component can be adjusted through the air pump system to achieve the center guide restraint and surface protection of the inner layer pipes with different outer diameters. It ensures that the inner layer pipe does not have a large lateral and circumferential shaking during the transportation process, and the entire mechanism is highly versatile and easy and quick to operate.

[0031] 3. The steel wire composite forming device is cleverly designed and has multiple functions: The steel wire composite forming device realizes the revolution and rotation of the rope drum around the inner tube through the transmission of the planetary gear system, thereby completing the winding and releasing of the steel wire. It has a compact structure, high transmission efficiency, and can accurately control the position and speed of the steel wire winding. In addition, the single power of a drive control mechanism is used to realize the revolution of the rope winding mechanism around the inner tube and the self-rotation of the rope during the revolution, which simplifies the equipment structure, reduces energy consumption, improves production efficiency, and can accurately control the rope release speed to ensure the quality and stability of the steel wire winding.

[0032] 4. Rapid tightening and pressing device enhances connection strength: The set rapid tightening and pressing device can make the steel wire instantly pull and press when it is wrapped around the surface of the inner tube, press it into the surface of the high-temperature inner tube, and better adhere to it during the cooling process of the inner tube, so as to avoid the loosening of the steel wire when the subsequent product is bent and used. By controlling the speed of the counter-rotating motor, the pulling and pressing amplitude of the steel wire can be controlled to ensure the winding effect, effectively improve the connection strength between the steel wire and the inner tube, and ensure the quality of the composite pipe.

[0033] 5. Reasonable cooling and drying design, saving resources and ensuring quality: The inner tube cooling unit sprays coolant to the inner tube through the cooling nozzle to accelerate the solidification of the inner tube, so that the inner tube and the steel wire embedded in the outer wall surface are better fitted, fixed and hardened. At the same time, the coordinated design of the cooling pool and the cooling nozzle realizes the recycling of coolant, saving resources and reducing production costs. The drying equipment adopts a pipeline drying drum, which can shape the inner tube with steel wire wrapped around the cooled surface, so that the pipe can achieve better physical properties and dimensional accuracy. The pipeline drying drum has a simple structure and good drying effect, which is conducive to improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following is a detailed description of the embodiments of the technical solution of the present invention in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present invention. Figure 1-Figure 11 as shown in .

[0048] Embodiment 1: A steel wire mesh reinforced polyethylene composite pipe forming production machine comprises a protective support and restraining mechanism, wherein the protective support and restraining mechanism is arranged downstream of an upstream inner layer pipe forming machine and is used to guide, restrain and protect the inner layer pipe 39 conveyed thereby, and a steel wire composite forming device is installed at intervals downstream of the protective support and restraining mechanism, and the steel wire composite forming device is used to compositely form the steel wire 36 on the outer side wall of the inner layer pipe 39 in a downwardly pulled and conveyed state as required, and an inner layer pipe cooling unit is provided downstream of the steel wire composite forming device, and a front support mechanism and a rear support mechanism are respectively installed upstream and downstream of the inner layer pipe cooling unit, and a drying device is installed downstream of the rear support mechanism.

[0049] All components work together, from the protection of the inner layer pipe, steel wire 36 winding, cooling and shaping to drying, to form a complete set of composite pipe production process, to ensure that the produced composite pipe is of reliable quality, each part is tightly connected, and the performance is stable.

[0050] In any of the above schemes, it is preferred that the wire mesh reinforced polyethylene composite pipe forming production machine is installed between the inner layer pipe forming machine and the outer layer pipe forming machine.

[0051] The production process is made more compact and reasonable, and the inner layer tube 39 is directly transported to the outer layer tube forming machine for outer tube laying after being wound with the steel wire 36, thereby reducing the pipe transportation link, improving production efficiency and reducing production costs.

[0052] The wire mesh reinforced polyethylene composite pipe forming production machine in the present invention is mainly used for laying steel wire 36 on the surface of the inner layer pipe 39 formed by the upstream inner layer pipe forming machine. During the processing, the inner layer pipe 39 just pulled out of the inner layer pipe forming machine is guided and protected by the protective support and restraint mechanism. The traction force of the entire inner layer pipe 39 is provided by the traction equipment at the end.

[0053] When the inner tube 39 is being transported to the outer tube forming machine downstream, it needs to pass through the protective support and constraint mechanism in sequence (constraint guidance is performed inside the protective support and constraint mechanism while protecting the outer surface of the high-temperature inner tube 39 which is in a relatively soft hardness). As the inner tube 39 continues to move forward, it will naturally cool down while the surface is still in a soft state. When the inner tube passes through the steel wire composite forming device, the steel wire composite forming device relies on its own operation and the continuous downstream transportation of the inner tube 39 to continuously spirally wrap the steel wire 36 around the outer surface of the inner tube 39. During the operation of the steel wire composite forming device, not only can the steel wire 36 be wrapped around the surface of the inner tube 39, but the steel wire 36 can also be pressed inward to a certain depth along the surface of the soft inner tube 39 during the winding process as needed. At this time, during the subsequent solidification process of the inner tube 39, the steel wire 36 and the inner tube 39 will be better fused into one, thereby improving the composite effect and preventing the inner tube 39 from being separated from the steel wire 36 on the surface due to excessive bending during the bending process after the entire composite tube is formed.

[0054] The inner tube 39 in a horizontal conveying state downstream will enter the steel wire composite forming device after being supported and guided by the front supporting mechanism. Under the action of the steel wire composite forming device, the steel wire 36 can be spirally wound on the surface. When the inner tube wrapped with the steel wire 36 continues to be conveyed downstream, it will pass through the inner tube cooling unit in turn, and the solidification of the inner tube 39 will be accelerated inside the inner tube cooling unit, so that the inner tube 39 and the steel wire 36 embedded in the outer wall surface thereof can be better fitted, fixed and hardened.

[0055] After being cooled by the inner tube cooling unit, the inner tube 39 with the steel wire 36 spirally wound on the surface will continue to be transported downstream under the action of the rear supporting mechanism, the upstream front supporting mechanism and the external traction force. During the transportation, it will be shaped through the drying equipment. After shaping, the inner tube 39 with the steel wire 36 wound on the surface will be sent to the downstream outer tube forming machine for laying and forming of the outer tube, and finally the entire composite tube will be extruded into shape.

[0056] In any of the above schemes, it is preferred that the protective supporting and restraining mechanism includes two spaced-apart pipe protectors, the two pipe protectors are coaxial and relatively spaced-apart, and the inner layer pipe 39 moves through the central channels of the two pipe protectors in sequence during downward transportation; the pipe protector includes an annular positioning annular pipe 1, the positioning annular pipe 1 is vertically fixed, and lifting cylinders 2 are fixedly installed at intervals on both sides of the bottom of the positioning annular pipe 1, the two lifting cylinders 2 are in a synchronous lifting state or a synchronous locking state when working, the bottoms of the two lifting cylinders 2 are fixed to the top of a horizontal ground seat 3, the two positioning annular pipes 1 are connected by a horizontally arranged total air intake pipe 4, the total air intake pipe is connected to an external air pump system, and a pneumatic linkage restraining component is installed on each positioning annular pipe 1 along its circumference, and each pneumatic linkage restraining component cooperates to realize the restraint and guidance of the outer wall of the inner layer pipe 39 passing through the center of the positioning annular pipe 1.

[0057] It should be noted that: when the protective support and restraint mechanism is working, the two pipe protectors are installed above the ground at intervals and symmetrically, so that the upstream inner layer pipe 39 in a high-temperature state can pass through its center. In the process of the inner layer pipe 39 passing through the pipe protector, the pipe protector can achieve center guide constraint and surface guide protection.

[0058] According to the outer diameter of the current inner tube 39, the air pressure linkage restraint component is adjusted in coordination with the external air pump system. When the air pressure linkage restraint component is controlled to work, the internal working end of each pipeline protector can reach the designated position as required, so that the current inner tube 39 can pass through without causing excessive lateral and circumferential shaking, thus achieving the purpose of guidance and protection. The entire pipeline protector can be adjusted as required to match the use of inner tubes 39 of different outer diameters. The entire pipeline protector has strong versatility when used and is simple and quick to operate.

[0059] The protective support and restraint mechanism can adjust the air pressure linkage restraint component through the air pump system according to the outer diameter size of the inner layer tube 39, so as to achieve the center guide restraint and surface protection of the inner layer tube 39 with different outer diameters, and ensure that the inner layer tube 39 does not have large lateral and circumferential shaking during the transportation process. It has strong versatility and is easy and quick to operate.

[0060] In any of the above schemes, it is preferred that a connecting outer tube seat 5 is fixedly installed on the outer side wall of the main air intake duct 4, and a temperature measuring probe 6 is installed at the bottom of each connecting outer tube seat 5. The working end of each temperature measuring probe 6 is downward toward the upper surface of the inner tube 39 at its corresponding position and is used to measure the temperature of the surface of the inner tube 39.

[0061] At the same time, each temperature measuring probe 6 can monitor and measure the surface temperature of the inner tube 39 during the transportation process and promptly feed back to the control center for recording, so as to better realize the parameter control when the inner tube 39 is cooled and formed by the subsequent inner tube cooling unit, and better control the rational use of the inner tube cooling unit.

[0062] By monitoring the surface temperature of the inner tube 39 and feeding it back to the control center, data support can be provided for the subsequent cooling and shaping parameter control of the inner tube cooling unit, thereby improving the rationality of the use of the cooling unit and ensuring the quality of tube forming.

[0063] In any of the above schemes, it is preferred that the pneumatic linkage restraint component includes a plurality of radial restraint pistons 7 arranged on the inner ring side wall of the positioning annular tube 1, the outer end of each radial restraint piston 7 is integrally formed with the positioning annular tube 1 and the interiors of the two are interconnected, a disc 8 is fixedly installed at the end of the cylinder of each radial restraint piston 7, and an arc-shaped silicone restraint seat 9 is fixedly installed at the telescopic end of the piston rod of the radial restraint piston 7, the inner arc surface of the arc-shaped silicone restraint seat 9 is in contact with the surface of the inner layer tube 39 passing through the center of the positioning annular tube 1, and adjusting cylinders 10 are symmetrically and spaced apart on both sides of each piston rod, the outer ends of the cylinders of the two adjusting cylinders 10 are fixed on the surface of the disc 8, and the piston rod of each adjusting cylinder 10 is fixed on the outer surface of the arc-shaped silicone restraint seat 9, and the two adjusting cylinders 10 are in a synchronous telescopic state when working.

[0064] The circumferential cooperation of the plurality of arc-shaped silicone restraining seats 9 can play a role in circumferential restraint and guidance for the inner tube 39 , thereby preventing the inner tube 39 from circumferentially swinging and shaking.

[0065] The inner arc surface of the arc-shaped silicone restraining seat 9 is spaced 0.2 mm to 0.3 mm from the surface of the inner tube passing through the center of the positioning annular tube 1 .

[0066] When it is necessary to make the bending radius of the arc-shaped silicone constraint seat 9 match the outer surface radius of the current inner layer tube 39 as much as possible, an adjusting cylinder 10 is installed on both sides of each arc-shaped silicone constraint seat 9. By controlling the synchronous extension and contraction of the two adjusting cylinders 10, the degree of opening of the entire arc-shaped silicone constraint seat 9 or the retraction of both ends can be controlled, so that the current arc-shaped silicone constraint seat 9 can better match the surface of the inner layer tube 39. Since the arc-shaped silicone constraint seat 9 is made of high-temperature resistant silicone material, it can effectively play the role of protection and restraint when in contact with the inner layer tube 39. At the same time, its surface texture is soft and will not damage the surface of the inner layer tube 39.

[0067] Controlling the lifting height of the two lifting cylinders 2 in the protective support and restraint mechanism can achieve the purpose of controlling the center height of the two pipeline protectors, and effectively ensure the centering and matching of the inner layer pipes 39 under different height conveying states.

[0068] In any of the above schemes, it is preferred that the steel wire composite forming device includes a horizontally arranged center guide gear tube 11, the central tube cavity of the center guide gear tube 11 is for the inner layer tube 39 to pass through, a planetary gear system positioning mechanism is installed at the middle outer wall of the center guide gear tube 11, a rope winding mechanism is installed at the right end of the planetary gear system positioning mechanism, a drive control mechanism is installed below the planetary gear system positioning mechanism, and a ground-connected bearing seat 12 is installed on the left side of the planetary gear system positioning mechanism, the left end of the center guide gear tube 11 is cooperatedly installed in the axial hole of the ground-connected bearing seat 12, and the planetary gear system positioning mechanism is used to drive the rope winding mechanism to spirally wind the steel wire 36 around the outer wall of the inner layer tube 39.

[0069] The various components work together to achieve the spiral winding of the steel wire 36 on the outer wall of the inner tube. The structure is reasonably designed and the operation is stable and reliable, which can meet different production needs.

[0070] In any of the above schemes, it is preferred that the rope winding mechanism includes a central gear 13 integrally formed on the middle outer wall of the central guide gear tube 11, a large ring gear 14 is arranged on the periphery of the central gear 13, and a plurality of ring gear outer gears 15 are arranged on the outer wall of the large ring gear 14, the ring gear outer gear 15 is connected and matched with the driving control mechanism thereunder, and a plurality of planetary gears 16 are arranged in the space between the central gear 13 and the large ring gear 14, each of the planetary gears 16 is respectively meshed with the inner gear teeth of the central gear 13 and the large ring gear 14, and the two ends of the planetary wheel shaft 17 of each of the planetary gears 16 are respectively plugged into and matched with the insertion holes on the corresponding left and right sides of the planetary carrier 18, and the middle part of each of the planetary carriers 18 is respectively sleeved on the outer wall of the central guide gear tube 11 On the side wall, a frame support tube 19 is fixedly connected to the middle through hole of the left side wall of the planetary frame 18 on the left side, and the outer wall of the left end of the frame support tube 19 is inserted in a vertical shaft seat 20, and the vertical shaft seat 20 is fixedly arranged. A swing arm 21 is arranged on the right side of the planetary frame 18 on the right side, and one end of the swing arm 21 is movably sleeved on the outer wall of the right end of the center guide gear tube 11, and the other end of the swing arm 21 is movably sleeved on the outer wall of one of the longer planetary axles 17. The right end of the planetary axle 17 with a longer length currently extends to the right and is coaxially connected with the rope drum 22, and the rope drum 22 is wound with a steel wire 36 for winding an inner layer tube 39. When the planetary axle 17 with a longer length currently rotates, it can drive the rope drum 22 to rotate on a fixed axis to realize the retraction and release of the steel wire 36.

[0071] Through the transmission of the planetary gear system 16, the rope drum 22 can revolve and rotate around the inner tube 39, thereby completing the winding and unwinding operations of the steel wire 36. It has a compact structure and high transmission efficiency, and can accurately control the winding position and speed of the steel wire 36.

[0072] Embodiment 2: Compared with Embodiment 1, this embodiment is different in that it also includes the following technical features: In any of the above schemes, it is preferred that the drive control mechanism includes a total drive pinion 23 arranged below the ring gear outer gear 15, the total drive pinion 23 is meshed with the ring gear outer gear 15, and a total drive motor 24 is arranged on the right side of the ring gear outer gear 15, the total drive motor 24 is used to drive the total drive pinion 23 to operate and drive the ring gear outer gear 15 and the large ring gear 14 inside it to rotate. When the large ring gear 14 rotates, it will drive each planetary gear to rotate and revolve, and the planet carrier 18 will follow to rotate.

[0073] When the planetary gear rotates, it will drive the planetary gear 16 coaxially connected to it to rotate. When the planetary gear 16 revolves around the central gear 13, it will drive the rope drum 22 connected to one of the longer planetary gear shafts 17 to revolve around the periphery of the inner tube 39, thereby driving the winding of the steel wire 36 on the rope drum 22, and cooperating with the axial movement of the inner tube 39 itself to realize the spiral winding of the steel wire 36 on the outer wall of the inner tube 39. During the winding process of the steel wire 36, considering that the steel wire 36 needs to be effectively released, the self-rotation of the planetary gear shaft 17 with a longer length is relied upon to drive the fixed-axis rotation of the rope drum 22 connected to it, thereby realizing rapid rope release. When designing the rope release, the transmission ratio between the inner teeth of the current planetary gear 16, the central gear 13 and the large gear ring 14 is pre-controlled, so as to achieve the purpose of controlling the rope release speed as needed.

[0074] The steel wire composite forming device provided here can rely on the single power of a driving control mechanism below to drive the entire rope winding mechanism to revolve around the inner layer tube 39 and rotate to release the rope during the revolution, and the single power can complete the double-step operation of rope winding and rope releasing.

[0075] The rope winding mechanism is driven by a single power of a driving control mechanism to realize the revolution of the rope winding mechanism around the inner layer tube 39 and the self-rotation of the rope during the revolution, which simplifies the equipment structure, reduces energy consumption, improves production efficiency, and can accurately control the rope releasing speed to ensure the quality and stability of the winding of the steel wire 36.

[0076] When the steel wire composite forming device is working, the driving control mechanism is started to operate. When the driving control mechanism is operating, the main drive motor 24 drives the main drive pinion 23 to operate. When the main drive pinion 23 operates, it can drive the large ring gear 14 that is meshed with it and is in a fixed axis limit state to rotate on a fixed axis. When the large ring gear 14 rotates on a fixed axis, it can drive the various planetary gears 16 and the planetary wheel shaft 17 to revolve in coordination with the internally fixed central gear 13 and the central guide gear tube 11, and realize self-rotation while revolving. When the planetary wheel shaft 17 revolves, it will revolve around the central gear 13 and the central guide gear tube 11. , and the inner tube 39 passing through the center guide gear tube 11 is coaxial therewith, so the planetary shaft 17 will also revolve around the inner tube 39 in the state of conveying to the right downstream, so that the rope drum 22 fixedly connected to the right end of the planetary shaft 17 with a longer length will revolve around the inner tube 39 to achieve winding the steel wire 36 around the inner tube 39; during the winding process, the rotation of the longer planetary shaft 17 will drive the rope drum 22 to rotate, thereby realizing the release of the steel wire 36, ensuring the smoothness of the winding of the steel wire 36, and controlling the release speed of the steel wire 36 to be consistent with the winding speed of the steel wire 36 onto the inner tube 39.

[0077] Rope end covers 25 are formed on both sides of the rope drum 22, and a quick rope tightening and bonding device is installed on the right side of the left rope end cover 25. The quick rope tightening and bonding device is used to pull and press the end of the steel wire 36 just wound on the surface of the inner layer tube 39 toward the soft surface of the inner layer tube 39 and make the steel wire 36 be crimped and bonded to the inner layer tube after an indentation groove is pressed on the surface of the inner layer tube 39.

[0078] The fast rope tightening and pressing device can instantly pull and press the steel wire 36 when it is wound on the surface of the inner tube 39, press it into the surface of the high-temperature inner tube 39, and better adhere it during the cooling process of the inner tube 39 to prevent the steel wire 36 from loosening when the subsequent product is bent and used. By controlling the speed of the counter-rotating motor 27, the pulling and pressing amplitude of the steel wire 36 can be controlled to ensure the winding effect.

[0079] The rope clamp 25 is provided with a locating bracket 26 on the right side wall of the rope stopper end cover 25 on the left side of the outer side of the rope winding drum 22, and the locating bracket 26 on the right side wall, the left and right ends of the locating bracket 26 are both movable through the guide through hole 40 on the rope stopper end cover 25 at the corresponding position through the guide long shaft 37, and a limit plate 38 is fixed at the end of each of the guide long shafts 37, and two counter-rotating motors 27 are fixed at intervals on the rear side wall of the locating bracket 26, and a friction rope tightening roller 28 is fixedly installed on the motor shaft of each of the counter-rotating motors 27, and a space for the steel wire 36 to pass through is provided between the two friction rope tightening rollers 28. When the two friction rope tightening rollers 28 rotate in opposite directions, the steel wire 36 at the current position is driven to be quickly pulled and tightened, and the steel wire 36 section on the surface of the inner layer tube that has just been wound around the outer surface and is still in a soft state will be quickly pulled downward and pressed into the outer surface of the inner layer tube 39 to form a rope pressing groove and then adhere.

[0080] The structure is simple, and the friction rope tightening roller 28 is driven to rotate counter-rotating by the counter-rotating motor 27 to achieve rapid tension, compression and adhesion of the steel wire 36, effectively improving the connection strength between the steel wire 36 and the inner layer pipe 39, and ensuring the quality of the composite pipe.

[0081] The main function of the fast rope tightening and pressing device set here is to improve the instantaneous tension and compression of the steel wire 36 when it is wound on the surface of the inner layer tube 39, so that the steel wire 36 can be quickly pressed into the surface of the inner layer tube in a high temperature state, and then achieve better adhesion with the steel wire 36 in this position during the continued cooling of the inner layer tube 39, thereby ensuring the effect of subsequent winding of the steel wire 36 and avoiding the probability of loosening of the steel wire 36 when the subsequent product is bent and used. Reasonable control of the rotation speed of the counter-rotating motor 27 can control the amplitude of the downward pulling and pressing of the steel wire 36.

[0082] When the steel wire 36 wound on the rope drum 22 is continuously wound down, there is a square tension on the steel wire 36 along the length of the rope drum. At this time, the corresponding guide shaft 37 will move axially along the guide through hole 40 on the guide shaft 37 to ensure that the entire positioning bracket 26 and the components thereon follow to achieve reciprocating swing, and ensure that the steel wire 36 and the two friction rope tightening rollers 28 maintain a suitable angle to avoid friction locking.

[0083] In any of the above schemes, it is preferred that the inner layer tube cooling unit includes a fixed cooling pool 29, a cooling hood 30 for the inner layer tube 39 to pass through is installed above the cooling pool 29, and a plurality of cooling nozzles 31 are installed at intervals on the top of the internal space of the cooling hood 30, each of the cooling nozzles 31 is used to spray cooling liquid onto the upper surface of the inner layer tube 39, and each of the cooling nozzles 31 is connected to the water outlet at the bottom of the cooling pool 29 through a pump pipeline, and the sprayed cooling liquid falls back into the cooling pool 29.

[0084] Cooling liquid is sprayed onto the inner tube 39 through the cooling nozzle 31 to accelerate the solidification of the inner tube 39, so that the inner tube 39 and the steel wire 36 embedded in the outer wall surface thereof can be better fitted, fixed and hardened. The coordinated design of the cooling pool 29 and the cooling nozzle 31 realizes the recycling of the cooling liquid, saves resources and reduces production costs.

[0085] In any of the above schemes, it is preferred that the front supporting mechanism includes a plurality of fixed-axis driven front rollers 32, and a high-temperature resistant friction belt 33 is wrapped around the periphery of each of the front rollers 32, and the top of the high-temperature resistant friction belt 33 is in contact with the surface of the inner layer tube 39 and the bottom of each spirally wound steel wire 36.

[0086] When each self-rotating front roller 32 drives the high temperature resistant friction belt 33 to rotate, it can cooperate with the external traction force and rely on the friction force of the high temperature resistant friction belt 33 to drive the inner layer pipe 39 to move downstream. At the same time, its main function is to support the inner layer pipe.

[0087] In any of the above schemes, it is preferred that the rear supporting mechanism includes a plurality of rear drive rollers 34 rotating on a fixed axis, the top of each rear drive roller 34 abuts against the bottom surface of the inner layer tube 39 and the bottom of each spirally wound steel wire 36, and each rear drive roller 34 is individually configured with a drive member.

[0088] When each rear driving roller 34 rotates, it can cooperate with the external traction force and rely on the friction force to drive the inner layer pipe to move downstream. At the same time, its main function is to support the inner layer pipe.

[0089] In any of the above schemes, it is preferred that the drying equipment uses a pipe drying drum 35. The pipe drying drum 35 can shape the inner layer pipe 39 with the steel wire 36 wound around the surface after cooling, so that the pipe material can achieve better physical properties and dimensional accuracy, and the pipe drying drum 35 has a simple structure and good drying effect, which is conducive to improving production efficiency.

[0090] Specific working principle: First, the inner tube 39 with high temperature and relatively soft texture is produced by the upstream inner tube forming machine. Under the traction force of the terminal traction device, the inner tube 39 passes through the protective support constraint mechanism in sequence. The two pipe protectors in the protective support constraint mechanism provide central guidance constraint and surface protection. By adjusting the air pressure linkage constraint component and the arc-shaped silicone constraint seat 9, the inner tube 39 is ensured to be transported stably. At the same time, the temperature measuring probe 6 monitors the surface temperature of the inner tube 39.

[0091] The inner tube cools naturally during the transportation process but the surface is still soft, and then enters the steel wire composite forming device. The main drive motor 24 in the drive control mechanism drives the main drive pinion 23 to operate, so that the large gear ring 14 rotates, and then drives the planetary gear 16 and the planetary wheel shaft 17 to revolve and rotate, so that the rope drum 22 revolves around the inner tube 39 to wind the steel wire 36. At the same time, the longer planetary wheel shaft 17 rotates to drive the rope drum 22 to release the rope, and the fast rope tightening press and adhesive presses the end of the newly wound steel wire 36 into the surface of the inner tube 39 and adheres it.

[0092] The inner tube 39 wrapped with the steel wire 36 continues to be transported downstream, passing through the front supporting mechanism, and the front roller 32 drives the high temperature friction belt 33, and cooperates with the external traction force to send the inner tube 39 into the inner tube cooling unit. The cooling nozzle 31 in the cooling unit sprays the cooling liquid to the inner tube 39 to accelerate its solidification and shape, so that the steel wire 36 and the inner tube are better fitted.

[0093] The cooled inner tube 39 is continuously transported under the action of the rear supporting mechanism, and the rear driving roller 34 cooperates with the external traction force to drive the inner tube 39 to move, and finally enters the drying equipment, and is shaped by the pipeline drying drum 35. The shaped inner tube 39 with the steel wire 36 wound on the surface is sent to the downstream outer tube forming machine for laying and forming of the outer tube, and finally the entire composite tube is extruded.
