Description

Technical Field

[0001] The invention relates to the technical field of pipeline processing and transportation, and in particular to a transportation device for polyethylene winding processing of thermal insulation pipes. Background Art

[0002] The spray-wrap polyurethane pipe insulation technology was first born in Europe and then used in the United States. In recent years, this technology has been widely used abroad. In recent years, the spray method has been greatly developed. Its process first treats the steel pipe with anti-corrosion, and then sends it to the spraying area. The foam polyurethane raw materials are mixed and sprayed on the surface of the steel pipe under high pressure. After the polyurethane foam is solidified, the polyethylene film is extruded by the polyethylene extruder in the winding area, and then the polyethylene film is multi-layered and wrapped around the outer layer of the polyurethane foam, and then cooled with water to form a composite insulation pipe. However, the polyurethane insulation pipes in the prior art are generally relatively heavy, and the manual feeding and unloading operations are not very reasonable, time-consuming and labor-intensive, and the space required for the crane to lift and transport is very large, and the cost is high. It is impossible to achieve the purpose of high cost performance and reasonable resource allocation while efficiently and conveniently processing the automatic feeding and unloading operations. At the same time, further analysis shows that in the actual polyethylene film winding operation of the polyurethane insulation pipe, most manufacturers generally use a clamp to clamp the outer end and rotate it, but this method requires a larger clamp structure for larger insulation pipes, and the corresponding cost will be very high. At the same time, external clamping requires a sufficiently large clamping force. For the insulation pipe, a large and unreasonable clamping force is also prone to deformation at the port, resulting in defects in the insulation pipe processing quality. Moreover, the external clamping method will also cause a blind spot in the polyethylene film winding, that is, the position of the clamping end of the insulation pipe cannot be wound, and this place cannot be used, resulting in a waste of insulation pipe resources. At the same time, the polyethylene winding process and the cooling process in most factory areas are separated, and the insulation pipe still needs to be transported again, which is time-consuming and labor-intensive, and the space utilization is not reasonable. In other words, it is impossible to achieve the insulation pipe processing quality and efficient resource utilization effect on the basis of reasonable and efficient insulation pipe fastening, support and rotation operations. At the same time, the insulation pipe winding process and cooling process can also be structurally upgraded and transformed, saving time and labor, and improving the insulation pipe winding operation transportation efficiency and processing quality. For this reason, we need a conveying equipment for polyethylene winding processing of insulation pipes. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] It should be noted that, in the specific implementation of the present invention, the possible terms such as "first" and "second" and other relational terms are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the possible terms such as "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of further restrictions, the possible statements "including one" and other defined elements do not exclude the existence of other identical elements in the process, method, article or equipment including the elements.

[0020] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "provided with" that may appear should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0021] Example: Figures 1 to 10 As shown: A conveying device for polyethylene winding processing of insulated pipes, comprising a support seat 1, a hoisting mechanism 2, a winding mechanism 3 and a cooling mechanism 4; the present invention has a reasonable structural design, and can complete efficient, convenient and automated loading and unloading operations, while optimizing the internal support fastening structure, ensuring the processing quality of the insulated pipe, simplifying the processing procedures, and improving the efficiency of the winding operation of the insulated pipe. Among them, the support seat 1 is distributed on the left and right; support legs can be set at the bottom for support. A movable mounting seat 5 is also provided on the support seat 1, and the mounting seat 5 itself remains extended forward and backward. The mounting seats 5 are two symmetrically distributed on the left and right, and can complete the operation of the two mounting seats 5 approaching or moving away synchronously. Specifically, if Figure 4 and Figure 5 As shown: the bottom end surface of the mounting seat 5 is provided with a slot 51, and the upper end surface of the support seat 1 is provided with a support rail 52, and the support rail 52 is matched with the slot 51. Among them, the support rail 52 is fixedly installed on the support seat 1 by screws. With this arrangement, the mounting seat 5 can move left and right along the support rail 52. Two auxiliary plates 11 distributed left and right are also provided on the support seat 1; the two can be connected and fixed by welding. A mobile motor 12 is installed on one side of the support seat 1 through a bracket. The mobile motor 12 adopts a servo control motor, and the displacement control is more accurate. The output end of the mobile motor 12 is connected to a rotating shaft 13, and the rotating shaft 13 is distributed left and right. Two threaded parts 14 with opposite left and right rotation directions are also provided on the rotating shaft 13; the rotating shaft 13 passes through the auxiliary plate 11 and the mounting seat 5, and the rotating shaft 13 and the auxiliary plate 11 are connected by a bearing; the two threaded parts 14 of the rotating shaft 13 are respectively connected and installed with the corresponding mounting seat 5. In this embodiment, the conveying equipment is connected to an external power supply through an electric wire to achieve electrical drive.

[0022] The purpose of such a setting is that when the mobile motor 12 starts to rotate forward, the rotating shaft 13 starts to rotate clockwise. Since the two threaded parts 14 of the rotating shaft 13 are respectively connected to the two mounting seats 5, the auxiliary cooperation of the supporting slide rail 52 and the card slot 51 plays a good guiding and limiting role. Therefore, the rotating shaft 13 will drive the two mounting seats 5 to approach synchronously, which corresponds to the loading-fastening operation state of the insulation pipe. When the mobile motor 12 starts to reverse, the rotating shaft 13 starts to rotate counterclockwise. Since the two threaded parts 14 of the rotating shaft 13 are respectively connected to the two mounting seats 5, the rotating shaft 13 will drive the two mounting seats 5 to start moving away synchronously, which corresponds to the unlocking-unloading operation state of the insulation pipe. The present invention can be widely used in the winding processing operations of insulation pipes of different lengths, specifications and models, and has stronger adaptability.

[0023] like Figure 5 As shown: In this embodiment, each mounting seat 5 is provided with an inner support member 6 for completing the inner support fastening and rotation operation of the insulation pipes of different diameters. Fig. 9 and Fig.10 As shown: the inner support member 6 includes a first motor 61, a first shaft 62, a limit plate 63, a second shaft 64, a second drive 65, a base plate 66, a movable sleeve 67 and an inner support structure 68. The first motor 61 is arranged on the mounting seat 5 through a bracket, and the first motor 61 also adopts a servo control motor. The first shaft 62 is rotatably arranged on the mounting seat 5, and one end is connected to the first motor 61, and the other end is fixedly installed with the limit plate 63; the purpose of such arrangement is to realize the rotation operation of the first motor 61 driving the first shaft 62. The second shaft 64 is relatively rotatably installed on the first shaft 62, and the second shaft 64 is connected to the mounting seat 5 through a bearing. The purpose of such arrangement is to ensure that the rotation of the first shaft 62 does not affect the state of the second shaft 64, and to provide a strong foundation for the subsequent automatic center positioning inner support drive of the thermal insulation pipe.

[0024] like Figure 5As shown: wherein, the second drive 65 is used to drive the second shaft 64 to rotate; in a preferred embodiment, the second drive 65 includes a driving wheel 651, a driven wheel 652 and a second motor 653. The second motor 653 is fixedly mounted on the mounting seat 5 through a bracket. The second motor 653 can be a servo-controlled motor, and the purpose of such a setting is to ensure the rotation of the second shaft 64, that is, to ensure the rotation speed of the second shaft 64 and the insulation pipe as a whole. In order to better achieve the polyethylene film winding processing quality of the insulation pipe, the rotation speed of the insulation pipe needs to be precisely controlled, and the rotation speed required for insulation pipes of different diameters and sizes is different, so the second motor 653 can also be a variable frequency motor to achieve the purpose of adjusting the rotation speed of the insulation pipe. The driving wheel 651 is sleeved and installed on the output shaft of the second motor 653; in such a setting, the second motor 653 drives the driving wheel 651 to rotate synchronously. The driven wheel 652 is fixedly mounted on the second shaft 64, and the driving wheel 651 and the driven wheel 652 are kept in meshing transmission. With such arrangement, the rotation of the second motor 653 will drive the rotation of the second shaft 64 through the cooperation between the driving wheel 651 and the driven wheel 652. Fig.10 As shown: the base plate 66 is circular and fixedly mounted on the second shaft 64 and located on the inner side of the mounting seat 5. The movable sleeve 67 is movably mounted on the second shaft 64, and one side is threadedly connected to the first shaft 62; that is, the movable sleeve 67 can move relative to the second shaft 64, and the rotation of the first shaft 62 will drive the movable sleeve 67 to move.

[0025] The present invention adopts the cooperation of the first motor 61, the first shaft 62, the limit plate 63, the second shaft 64, the second drive 65, the base plate 66, the movable sleeve 67 and the inner support structure 68. On the basis of realizing reasonable and efficient fixing, supporting and rotating operations of the insulation pipe, it can complete the polyethylene winding without blind spots and dead angles, and can achieve the purpose of improving the processing quality of the insulation pipe and fully utilizing the pipeline resources. The manufacturing process is simplified and the dynamic balance of the structure is improved. Compared with the clamping of the insulation pipe with the same fixing effect, on the basis of ensuring that the insulation pipe is sufficiently fixed and rotated, the uniformity of the insulation pipe support is improved, and there is no problem of end clamping deformation and the unusable blind spot of the winding processing, which can maximize the utilization rate of the insulation pipe material by 5%.

[0026] like Fig.10As shown: In this embodiment, the inner support structure 68 is used to complete the inner support and tightening operation of the insulation pipe. Specifically, the inner support structure 68 is a plurality of groups evenly distributed in an annular shape, and preferably four groups are used in this embodiment. Each group of the inner support structure 68 includes a linkage rod 681, an inner support rod 682 and a moving block 683. One end of the linkage rod 681 is rotatably connected to the movable sleeve 67, and the other end is rotatably connected to the inner support rod 682. Among them, the outer end surface of the inner support rod is arc-shaped, and the inner end surface is a planar structure. A moving groove 684 is provided on the substrate 66; the moving block 683 is adapted to be installed in the moving groove 684, and the moving block 683 is connected and fixed to the inner support rod 682, and is L-shaped as a whole. With such a configuration, the moving block 683 cooperates with the moving groove 684 to form a good guiding and limiting effect, the purpose of which is to realize the contraction and outward expansion movement of the inner support rod 682. Specifically, when the insulation pipe is transported to the designated position of the support seat 1, the insulation pipe is located at the left-right central axis of the support seat 1. In the initial state, the centers of the two mounting seats 5 and the two inner support members 6 are located on the left-right central axis of the support seat 1; the two inner support members 6 are at the maximum position away from each other. The inner diameter of the insulation pipe is large enough, and the inner support member 6 of this embodiment can be designed to be adapted.

[0027] In the initial state, the inner support rod 682 is in a fully retracted state. Then the moving motor 12 starts to rotate forward, and the two mounting seats 5 begin to approach each other until the inner support rod 682 of the inner support member 6 is completely inside the insulation pipe (specifically, this can be achieved through the auxiliary limit of the base plate 66). At this time, the left and right inner support members 6 are located at both ends of the insulation pipe. Next, the first motor 61 is turned on, and the first motor 61 will drive the first shaft 62 to rotate synchronously, and the second shaft 64 is stationary. The rotation of the first shaft 62 will drive the movement of the movable sleeve 67 threadedly connected thereto. Specifically, the first motor 61 rotates forward, and the first shaft 62 rotates clockwise. Under the cooperation of the limiting guide of the movable block 683 and the movable groove 684, the movable sleeve 67 will be driven to move along the second shaft 64 toward the direction close to the base plate 66. At this time, the inner support rod 682 on the movable sleeve 67 will be driven to expand outward, thereby realizing the support and tightening operation of the inner wall of the insulation pipe. Since multiple inner support rods 682 move synchronously, the automatic centering support operation of insulation pipes with different inner diameters can be realized, which is more stable. At the same time, the inner support rod 682 has a sufficiently large plate structure, which greatly enhances the inner support and tightening effect of the insulation pipe. The next step is to turn on the second motor 653, and the second motor 653 will drive the second shaft 64 to rotate. At this time, the second shaft 64 forms an integrated structure with the inner support structure 68 and the insulation pipe. Therefore, the rotation of the second shaft 64 will drive the inner support rod 682 and the insulation pipe as a whole to rotate at a preset speed, thereby completing the efficient winding process of the polyethylene film. Similarly, after the insulation pipe completes the winding process and the cooling process, the second motor 653 is turned off, and the first motor 61 is turned on and reversed to achieve the reverse movement of the moving sleeve 67, thereby completing the contraction movement of the inner support rod 682 and achieving the unlocking operation of the insulation pipe. Next, the moving motor 12 reverses, which will drive the mounting seat 5 and the inner support member 6 as a whole to move away from each other. At this time, the movement of the insulation pipe does not interfere, which is convenient for subsequent lifting, moving and conveying operations.

[0028] like Figure 1 As shown: In this embodiment, the hoisting mechanism 2 is used to drive the insulated pipe to be processed to rotate clockwise from the preset processing area to a preset angle to complete the loading and conveying operation, and can drive the insulated pipe after winding to continue to rotate clockwise at a preset angle to complete the unloading and conveying operation of the preset finished product area. Preferably, as Figure 3 As shown in FIG. 2 , the hoisting mechanism 2 includes a hoisting base 21, a rotating base 22, a fixing column 23, a traction arm 24, a hydraulic cylinder 25 and a hoisting claw 26. The hoisting base 21 is vertically distributed, as shown in FIG. Figure 1As shown, the hanging seat includes an end face and four supporting leg structures arranged at the lower end of the end face. The rotating seat 22 is arranged on the hanging base 21 through a bearing, that is, the rotating seat 22 and the hanging base 21 can rotate relative to each other but cannot move relative to each other. A vertically distributed rotating shaft 74 is arranged at the bottom of the rotating seat 22, and the two can be fixed by welding. The hanging base 21 is also equipped with a rotating motor 71 through a bracket. The rotating motor 71 can adopt a servo control motor to facilitate precise control of the rotation angle, such as Figure 2 As shown: In this embodiment, a material loading area to be processed (the SL area in the figure) is set in front of the lifting base 21, and a finished product unloading area (the XL area in the figure) is set behind the lifting base 21. At the same time, this embodiment can use the initialization setting of the rotating motor 71 to a single clockwise turning angle of 90 degrees, that is, to drive the traction arm 24 to turn 90 degrees clockwise. Taking the traction arm 24 located in the material loading area to be processed as the reference 0 degree as an example, the rotating motor starts a 90-degree turn, which will drive the traction arm 24 to rotate 90 degrees clockwise, thereby completing the loading operation of the insulation pipe material. At the same time, the rotating motor of this embodiment can also cooperate with the position sensors distributed at the four corners of the lifting base 21 to achieve precise position rotation. Figure 3 As shown: the output shaft of the rotating motor 71 is installed with the first wheel 72, and the second wheel 73 is installed on the rotating shaft 74, and the first wheel 72 and the second wheel 73 are kept in meshing transmission; the purpose of such arrangement is that when the rotating motor 71 is started, it will drive the first wheel 72 to rotate synchronously, and then the second wheel 73 and the rotating seat 22 can be synchronously rotated under the meshing transmission action of the first wheel 72 and the second wheel 73, and the whole rotation process keeps the steering and speed stable.

[0029] like Figure 3As shown: In this embodiment, the fixed column 23 is vertically distributed and the bottom end is welded and fixed to the rotating seat 22; at the same time, in order to enhance the stability, a plurality of reinforcing ribs 27 distributed in an annular manner can be added between the two. The traction arm 24 is vertically installed on the fixed column 23, and a reinforcing rib 27 is also provided between the two; such a configuration ensures that the traction arm 24 is sufficiently stable. The hydraulic cylinder 25 is vertically distributed, and one end is connected and installed on the traction arm 24, and the other end is connected to the lifting claw 26. Such a configuration completes the lifting and lowering movement of the lifting claw 26 through the telescopic change of the hydraulic cylinder 25. In a preferred embodiment, the lifting claw 26 includes a cross arm 261, a connecting arm 262 and a hydraulic claw 263. The cross arm 261 is arranged at the lower end of the hydraulic cylinder 25, and the two are vertically distributed. The cross arm 261 and the hydraulic cylinder 25 can be connected through a connector, one end of the connector is fixed to the hydraulic cylinder 25 by welding, and the other end is connected to the cross arm 261 by bolts. Both ends of the cross arm 261 are provided with fixing grooves 264; the cross arm 261 is long enough, and the depth of the fixing groove 264 is long enough. The connecting arm 262 is an L-shaped structure, and one end is inserted into the fixing groove 264 of the cross arm 261, and the two can be connected and fixed by a fastening bolt 265; the hydraulic claw 263 is arranged on the connecting arm 262, and the hydraulic claw 263 adopts the mechanical hydraulic gripping arm at the front end of the loader equipment. The specific structure is that the two claws are hinged, and each is driven by a corresponding hydraulic cylinder to realize the opening and contracting gripping operation. It is a prior art, so it is not repeated here.

[0030] In the initial state, the traction arm 24 is located directly above the material loading area to be processed, and the relative lengths of the cross arm 261 and the connecting arm 262 are adjusted to meet the requirements of conveying and loading insulation pipes of different lengths. In the initial state, the hydraulic claw 263 remains open. The staff starts the hydraulic cylinder 25 to extend, so that the hydraulic claw 263 is close to the insulation pipe, and then starts the hydraulic claw 263 to complete the gripping operation of the insulation pipe. In the next step, the hydraulic cylinder 25 is started to contract, thereby driving the hydraulic claw 263 and the insulation pipe to rise to a preset height as a whole. In the next step, the rotating motor is turned on, and the traction arm 24 is located in the material loading area to be processed as a reference 0 degree. When the rotating motor is started once and turns 90 degrees, it will drive the traction arm 24 to rotate 90 degrees clockwise, that is, the insulation pipe is conveyed directly above the support seat 1. In the next step, the hydraulic cylinder 25 descends to complete the unloading of the insulation pipe and then rises to the initial height, which does not affect the winding process of the polyethylene film, and then completes the loading process of the insulation pipe material, providing a strong foundation for the subsequent polyethylene film winding process and cooling process. After the polyethylene film winding and cooling processing of the insulation pipe is completed, the hydraulic cylinder 25 starts to extend, completes the gripping operation of the insulation pipe and then rises and resets. The next step is to start the rotating motor to drive the traction arm 24 to continue to turn 90 degrees clockwise to the unloading finished product area, and then move down to complete the unloading and conveying operation of the insulation pipe. The present invention further adopts the cooperation of the lifting base 21, the rotating seat 22, the fixed column 23, the traction arm 24, the hydraulic cylinder 25 and the lifting claw 26 to achieve efficient and convenient automated loading and unloading operations while achieving the purpose of high cost performance and reasonable resource allocation, thereby improving the winding and conveying efficiency of the insulation pipe.

[0031] like Figure 1 As shown: In this embodiment, the winding mechanism 3 includes a moving seat 31, a side wing plate 32, a lead screw 33, a guide rod 34, a drive motor 35 and a base 36. The moving seat 31 is arranged on the support seat 1 so as to be movable forward and backward; in a preferred technical solution, as Figure 6As shown: a fixed block 311 and a protrusion 312 are provided at the lower end of the movable seat 31, wherein the protrusion 312 is located at the center of the movable seat 31, and the fixed block 311 is located outside the protrusion 312. A fixed slide rail 38 is provided on the support seat 1, and the two are connected and fixed by screws, and the fixed slide rail 38 keeps extending forward and backward. The fixed block 311 is installed in a matching manner with the fixed slide rail 38; the purpose of such an arrangement is to play a good guiding and moving role. A support plate 15 is also provided on the support seat 1, and the support plate 15 is two distributed front and back, and the purpose is to provide a support carrier for the rotating rod 17. A fixed motor 16 is also provided on the support seat 1, and the fixed motor 16 is installed on the support seat 1 through a bracket, and a rotating rod 17 is also connected to one end, and the rotating rod 17 is connected to the support plate 15 through a bearing, and is threadedly connected to the protrusion 312. The purpose of such a setting is to adapt to the polyethylene winding processing of insulation pipes of different outer diameters, so as to avoid the problem that the insulation pipe with a larger diameter is closer to the polyethylene film and the insulation pipe with a smaller diameter is farther away from the polyethylene film in the prior art, which causes pulling and affects the unreasonable spraying of the coolant. That is, by adjusting the front and rear positions of the movable seat 31, the distance between the polyethylene film and the insulation pipe is adjusted. Specifically, the forward rotation of the fixed motor 16 will drive the rotating rod 17 to rotate clockwise. Under the cooperation between the fixed slide rail 38 and the fixed block 311, the rotating rod 17 will drive the movable seat 31 to move toward the front side of the support seat 1. At this time, the corresponding adjustment is close to the insulation pipe, which corresponds to the winding processing and cooling processing operations for the insulation pipe with a smaller outer diameter. On the contrary, the reverse rotation of the fixed motor 16 will drive the movable seat 31 to move backward. At this time, the corresponding adjustment is far away from the insulation pipe, which corresponds to the winding processing and cooling processing operations for the insulation pipe with a larger outer diameter, thereby realizing the rational use of resources and improving the processing quality and operation efficiency of the insulation pipe.

[0032] like Figure 6 As shown: In this embodiment, there are two side wing plates 32 that are symmetrically distributed on the left and right, and both are arranged on the movable seat 31; the two can be fixed by welding. The lead screw 33 is rotatably installed on the two side wing plates 32 distributed on the left and right; a bearing can be provided at the connection between the two. The driving motor 35 is installed on one side of the side wing plate 32 through a bracket and is connected to the lead screw 33; the driving motor 35 also adopts a servo control motor, the purpose of which is to accurately and smoothly control the rotation speed, and then adapt the rotation speed requirement of the insulation pipe through the moving speed of the polyethylene film to ensure the winding processing quality of the polyethylene film. The guide rod 34 is arranged between the two side wing plates 32 and is arranged parallel to the lead screw 33; the base 36 is arranged on the lead screw 33 and the guide rod 34, and is threadedly connected to the lead screw 33 and slidably connected to the guide rod 34; as shown Figure 7As shown: A winding rod 37 of an L-shaped structure is also provided on one side of the base 36 for installing a roll of polyethylene film. With such a configuration, the guide rod 34 plays a guiding role. When the polyethylene winding process is performed on the insulation pipe, the drive motor 35 starts to rotate forward, thereby driving the screw 33 to rotate clockwise. Under the limiting guiding action of the guide rod 34, the screw 33 will drive the base 36 to move smoothly to the right until the entire winding process of the insulation pipe is completed, without dead angles or residues, and the entire length of the insulation pipe can be utilized. In a preferred embodiment, Figure 8 As shown, a baffle 361 is hingedly installed on one side of the base 36, and a compression spring 362 is provided on the side of the baffle 361 away from the winding rod 37, and the baffle 361 is kept in the initial state to press the rolled polyethylene film on the winding rod 37. The purpose of such a setting is to facilitate the conveying and feeding of the polyethylene film, and at the same time ensure the compression of the polyethylene film to prevent it from being dislocated or slipping.

[0033] like Figure 8 As shown: In this embodiment, the cooling mechanism 4 includes a cooling chamber 41, a liquid pump 42 and a cooling nozzle 43. The cooling chamber 41 is opened inside the base 36 and is connected to an infusion tube, which leads to the outside. There is enough coolant in the cooling chamber 41. The liquid pump 42 is fixedly installed in the cooling chamber 41 by a bracket, and the cooling nozzle 43 is arranged on the base 36, and one end is connected to the liquid pump 42 and the other end is facing the insulation pipe. The cooling nozzle 43 and the winding rod 37 are both located in the middle of the base 36, and can be sprayed corresponding to the insulation pipe to ensure sufficient uniformity and rationality of resource utilization. In a preferred technical solution, the side wing plate 32 can be set as a structure that can be raised and lowered to ensure that the cooling nozzle 43 is always located in the middle of the insulation pipe. The present invention has a reasonable structural design, and the coolant spraying cooling process is integrated into the polyethylene film installation position, which simplifies the process, saves space, and has a compact structure. Compared with the winding and cooling processes with the same effect, the space is saved by more than 50%, the material is saved by about 25%, and the manufacturing cost is effectively reduced; at the same time, since the cooling is carried out next to the winding, there is no need to transport the insulation pipe, and efficient cooling can be quickly completed after the polyethylene winding, which greatly improves the efficiency and processing quality of the polyethylene winding process.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
