Description

Technical Field

[0001] This invention relates to the field of composite pipe production and processing technology, specifically a plastic composite pipe processing device. Background Technology

[0002] Reinforced PE pipe is a type of polyethylene composite pipe. During production, a layer of spiral steel wire is wound around the inner core pipe, and then a PE outer layer is wrapped around the surface. Reinforced PE pipe has the characteristics of strong pressure resistance and is widely used in urban water supply and drainage, agricultural irrigation and other engineering projects.

[0003] Existing technologies use either hot melt adhesive applied between the inner and outer plastics or grooved processing to fix the steel wire to the pipe. Of these two methods, applying hot melt adhesive has drawbacks such as complex process, waste of hot melt adhesive, and uneven application; while the grooved processing method involves many processing steps, is complex, wastes raw materials, and reduces production efficiency.

[0009] The synchronous drive assembly is mounted on the base and is used to drive the two sets of rotating winding assemblies to rotate and control the two sets of rotating winding assemblies to rotate synchronously in opposite directions. This causes the steel wires released by the two sets of rotating winding assemblies to be interlaced and wound around the outer wall of the pipe in opposite spiral directions, thereby forming a mesh structure on the outer wall of the pipe.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0042] In one embodiment, see [reference] Figures 1 to 15 A plastic composite pipe processing device includes: a base 1, a roller pressing conveying assembly 64, a rotary winding assembly 65, a synchronous drive assembly 66, an eddy current heating assembly 67, and a roller pressing cooling assembly 68.

[0043] Two sets of roller pressing conveyor assemblies 64 are provided, and the two sets of roller pressing conveyor assemblies 64 are installed at both ends of the base 1; two sets of brackets 7 are fixedly connected to the base 1; two sets of rotating winding assemblies 65 are provided, and the two sets of rotating winding assemblies 65 are rotatably installed in the two sets of brackets 7; the synchronous drive assembly 66 is installed on the base 1 and is used to drive the two sets of rotating winding assemblies 65 to rotate; the eddy current heating assembly 67 is installed on the discharge end side of the rotating winding assembly 65 and is used to rapidly heat the steel wire wound on the outer wall through electromagnetic eddy current, and the red-hot steel wire rope synchronously heats and melts the pipe around the steel wire; the roller pressing cooling assembly 68 is installed on the discharge end side of the eddy current heating assembly 67.

[0044] This invention first uses two sets of roller conveying assemblies 64 to roller convey the pipe. The pipe first enters two sets of rotating winding assemblies 65. At this time, the invention uses a synchronous drive assembly 66 to drive the two sets of rotating winding assemblies 65 to rotate, and controls the two sets of rotating winding assemblies 65 to rotate synchronously in opposite directions. Then, the steel wires released from the two sets of rotating winding assemblies 65 are interlaced with helical lines of opposite directions and wound around the outer wall of the pipe, thereby forming a mesh structure on the outer wall of the pipe. Then, it is passed through... The electromagnetic eddy current generated by the eddy current heating component 67 rapidly heats the steel wire wound on the outer wall. The red-hot steel wire rope simultaneously heats and melts the pipe material around the steel wire. Finally, the roller pressing and cooling component 68 presses the red-hot steel wire against the molten outer wall of the pipe, thereby pressing the steel wire into the outer wall of the pipe material. The red-hot steel wire is cooled, and the molten plastic on the outer wall of the pipe material is rapidly solidified, thereby fixing the steel wire rope into the solidified outer wall of the pipe material, completing the embedded processing between the steel wire and the pipe material.

[0045] In one instance of this embodiment, please refer to Figure 4The roller pressing conveyor assembly 64 includes a first fixed frame 2 fixedly connected to the base 1. Two sets of first rotating shafts 3 are rotatably connected inside the first fixed frame 2. Roller pressing conveyor rollers 4 are fixedly connected to the two sets of first rotating shafts 3. One end of the two sets of first rotating shafts 3 passes through the first fixed frame 2 and is fixedly connected to a gear set 5. A first motor 6 is fixedly connected to the first fixed frame 2. The output shaft of the first motor 6 is fixedly connected to the drive end of the first rotating shaft 3.

[0046] The roller pressing conveyor assembly 64 drives the first rotating shaft 3 to rotate via the first motor 6. The two sets of first rotating shafts 3 achieve synchronous reverse rotation under the drive of the gear set 5, which in turn drives the two sets of roller pressing conveyor rollers 4 to rotate synchronously in opposite directions. Finally, the pipe is conveyed at a uniform speed through the synchronously reverse rotating roller pressing conveyor rollers 4.

[0047] In one instance of this embodiment, please refer to Figures 1 to 13 The rotating winding assembly 65 includes a first rotating cylinder 8 rotatably connected within the bracket 7. One end of the first rotating cylinder 8 is fixedly connected to a mounting plate 9. A feed hole 10 is provided in the middle of the mounting plate 9. A third mounting hole 14 is provided on the mounting plate 9. A first mounting flange 16 is fixedly installed in the third mounting hole 14 by bolts. A mounting cylinder 15 is fixedly connected to the first mounting flange 16. A conical material cylinder 19 is fixedly installed in the mounting cylinder 15 through a second mounting flange 17 and a third mounting flange 18. The second mounting flange 17 and the third mounting flange 18 are connected by bolts.

[0048] The mounting plate 9 is provided with a second mounting hole 13. A first mounting bracket 20 is fixedly installed in the second mounting hole 13 by bolts. Multiple sets of first guide rollers 21 distributed in a circle are rotatably connected to the first mounting bracket 20. Multiple sets of second guide rollers 22 distributed in a circle are rotatably connected to the outer wall of the conical material cylinder 19 near the mounting cylinder 15. Multiple sets of second rotating shafts 23 distributed in a circle are rotatably connected to the outer wall of the discharge end of the conical material cylinder 19. An elastic rod 24 is fixedly connected to the second rotating shaft 23. A positioning ring 27 is fixedly connected to the end of the elastic rod 24 away from the second rotating shaft 23. A coil spring 25 is connected between the driving end of the second rotating shaft 23 and the conical material cylinder 19. A rolling contact wheel 26 is fixedly connected to the positioning ring 27 and the second rotating shaft 23 and rotatably connected to the elastic rod 24 near the pipe.

[0049] The wire rope passes between the first guide roller 21 and the first mounting bracket 20, and then enters the positioning ring 27. During this process, the wire rope is placed on the side of the second guide roller 22 away from the conical cylinder 19.

[0050] The rotary winding assembly 65 first selects conical cylinders 19 of different diameters according to the different pipes being processed, so that the conical cylinders 19 fit as closely as possible to the outer wall of the pipe. Then, when the pipe passes through the conical cylinder 19, the elastic rod 24 elastically fits against the outer wall of the pipe under the action of the coil spring 25. At this time, the steel wire enters the positioning ring 27 at a certain angle under the action of the first guide roller 21 and the second guide roller 22, thereby avoiding winding deviation caused by changes in the angle of the steel wire. Then, during the process of rotating and winding the steel wire, the smaller the distance between the conical cylinder 19 and the outer wall of the pipe, the smaller the angle between the steel wire and the outer wall of the pipe, the tighter the fit between the steel wire and the pipe, and the better the winding effect of the steel wire.

[0051] When the steel wire is wound, the first rotating drum 8 is first driven to rotate by the synchronous drive component 66, and the tube is controlled to move at a uniform speed through the feed hole 10 by the roller pressing and conveying component 64. At this time, the ratio between the feed speed of the tube and the rotation speed of the first rotating drum 8 can be controlled and adjusted by the different pitch of the steel wire spirally wound on the outside of the tube.

[0052] In one instance of this embodiment, please refer to Figures 1 to 13 The mounting plate 9 has multiple sets of circumferentially distributed first mounting holes 12 at its edge. Insert bolts 28 are installed in the first mounting holes 12, and fixing rods 29 are fixedly connected to the insert bolts 28. A telescopic hole 31 is provided inside the fixing rod 29, and a first threaded cylinder 32 is fixedly connected inside the telescopic hole 31. A mounting bolt 33 is threaded into the first threaded cylinder 32, and a mounting rod 30 is fixedly connected to the mounting bolt 33 through the telescopic hole 31. A screw head 39 is fixedly connected to the driving end of the mounting rod 30. A mounting seat 34 is fixedly connected to the outer wall of the mounting rod 30 and the fixing rod 29. A rotating seat 35 is rotatably connected to the mounting seat 34 via a damping bearing 38. A clamping plate 36 is fixedly connected to the rotating seat 35, and an insert cylinder 37 is fixedly connected to the inner side of the clamping plate 36. A wire roller 56 is provided between the clamping plates 36, and the wire roller 56 is slidably connected to the insert cylinder 37.

[0053] The rotating winding assembly 65 first selects a certain number of wire rollers 56 according to the different amounts of steel wire wound on the outer wall of the pipe, and then installs them into the first mounting hole 12 through the insertion bolts 28. At this time, the fixing rod 29 is fixedly connected to the mounting plate 9. Then, the wire rollers 56 can be inserted into the fixing rod 29, and one end of the wire rollers 56 is inserted through a set of insertion cylinders 37. Then, holding the mounting rod 30, the mounting bolts 33 are passed through the wire rollers 56 and inserted into the first threaded cylinder 32. The screw head 39 is tightened by wrench, so that the threaded connection between the mounting bolts 33 and the first threaded cylinder 32 drives the two sets of clamping plates 36 to clamp and retract. This clamps and fixes the wire drum 56, and the rotational connection of the two sets of rotating seats 35 achieves the rotational fixation of the wire drum 56. Then, when the wire drum 56 is rotated and released under the traction of the wire, the mounting seat 34 and the rotating seat 35 rotate synchronously under the drive of the wire drum 56. At this time, the damping bearing 38 will apply a damping force in the opposite direction of rotation between the mounting seat 34 and the rotating seat 35. The damping force acts on the wire, thereby keeping the wire taut and ensuring the uniform release of the wire. At the same time, the tension force acts between the wire and the outer wall of the pipe, thereby keeping the wire tightly attached to the outer wall of the pipe and preventing the wire from scattering.

[0054] In one embodiment, referring to 3, the synchronous drive assembly 66 includes two sets of second mounting brackets 57 fixedly connected to the base 1. A connecting shaft 58 is rotatably connected inside the second mounting bracket 57. A first bevel gear 59 is fixedly connected to one end of the connecting shaft 58, and a bevel gear disk 11 is fixedly connected to the other end of the first rotating cylinder 8. The bevel gear disk 11 and the first bevel gear 59 are meshed with each other. A first gear 60 is fixedly connected to the other end of the connecting shaft 58. Two sets of meshing second gears 62 are arranged between the two sets of first gears 60. The two sets of second gears 62 mesh with the two sets of first gears 60 respectively. A third motor 61 is fixedly connected to the base 1, and one set of second gears 62 is fixedly connected to the output shaft of the third motor 61.

[0055] The synchronous drive assembly 66 drives a set of second gears 62 to rotate via a third motor 61. The second gears 62 mesh with the first gears 60 to drive the two sets of first gears 60 to rotate synchronously in opposite directions. The first gears 60 drive the first bevel gears 59 to rotate via a connecting shaft 58. The first bevel gears 59 mesh with the bevel gear disk 11 to drive the two sets of first rotating cylinders 8 to rotate synchronously in opposite directions.

[0056] In one instance of this embodiment, please refer to Figures 1-4 The eddy current heating assembly 67 includes a power supply 40 connected to the base 1, and an eddy current coil 41 is fixedly connected to the output end of the power supply 40. The tube passes through the inside of the eddy current coil 41.

[0057] The eddy current heating component 67 supplies power to the eddy current coil 41 through the power supply 40, thereby generating eddy currents inside the steel wire. Through the resistance heating effect, electrical energy is converted into heat energy inside the steel wire, thereby rapidly heating the steel wire.

[0058] In one instance of this embodiment, please refer to Figure 4 , Figure 14 and Figure 15 The roller cooling assembly 68 includes a second fixed frame 42 fixedly connected to the base 1. Multiple sets of third rotating shafts 43 arranged in a circle are rotatably connected inside the second fixed frame 42. Two sets of lifting gears 44 are fixedly connected to the third rotating shafts 43. A second rotating cylinder 45 is arranged between the lifting gears 44. External gear rings 46 are fixedly connected to both ends of the second rotating cylinder 45. The external gear rings 46 mesh with the lifting gears 44. A second motor 47 is fixedly connected to the second fixed frame 42. The output shaft of the second motor 47 is fixedly connected to the drive end of the third rotating shaft 43.

[0059] A fixed cylinder 48 is fixedly connected inside the second rotating cylinder 45. A connecting rod 49 is slidably connected inside the fixed cylinder 48. One end of the connecting rod 49 is rotatably connected to a lifting frame 50 disposed inside the second rotating cylinder 45. A pressing roller 51 is rotatably connected inside the lifting frame 50. The pressing roller 51 is made of a material with high thermal conductivity. Multiple sets of heat-conducting fins 63 are fixedly connected to the inner wall of the pressing roller 51.

[0060] A second threaded cylinder 54 is fixedly connected inside the second rotating cylinder 45, and a screw 53 is threadedly connected inside the second threaded cylinder 54. A drive frame 52 is fixedly connected to the other end of the connecting rod 49. The drive frame 52 is rotatably connected to the screw 53, and a knob 55 is fixedly connected to the drive end of the screw 53.

[0061] The roller pressing and cooling assembly 68 first drives the screw 53 to rotate by turning the knob 55. The screw 53 is connected to the second threaded cylinder 54 by a thread, which converts the rotational motion of the screw 53 into the linear motion of the drive frame 52. The drive frame 52 drives the connecting rod 49 to extend and retract, the connecting rod 49 drives the lifting frame 50 to extend and retract, and the lifting frame 50 drives the pressing roller 51 to extend and retract, thereby pressing multiple sets of pressing rollers 51 tightly against the outer wall of the pipe. Thus, the relative rolling contact between the pipe and the pressing roller 51 is achieved through the rotational connection of the pressing roller 51. At the same time, the second motor 47 drives the third rotating shaft 43 to rotate, the third rotating shaft 43 drives the lifting gear 44 to rotate, and the lifting gear 44 drives the outer gear ring 46 to rotate through mutual meshing with the outer gear ring 46. The outer gear ring 46 drives the second rotating cylinder 45 to rotate, and the second rotating cylinder 45 drives the pressing roller 51 to rotate around the pipe, thereby realizing the roller pressing between the pipe and the steel wire.

[0062] At this time, with the linear movement of the pipe and the rotational movement of the pressing roller 51, the pressing roller 51 and the outer wall of the pipe undergo spiral movement. At this time, the adaptive rotational adjustment between the pressing roller 51 and the pipe can be achieved through the rotational connection between the lifting frame 50 and the connecting rod 49, thus avoiding structural damage caused by long-term sliding friction between the pressing roller 51 and the pipe.

[0063] Furthermore, while the pressing roller 51 is rolling the pipe and the steel wire, it absorbs the heat inside the steel wire and the molten pipe and discharges it through the heat-conducting fins 63, thereby rapidly cooling the steel wire and rapidly cooling and solidifying the plastic.

[0064] 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 principles of the present invention should be included within the protection scope of the present invention.

The wire rope passes between the first guide roller and the first mounting bracket, and then enters the positioning ring. During this process, the wire rope is placed on the side of the second guide roller away from the conical cylinder. The synchronous drive assembly is mounted on the base and is used to drive the two sets of rotating winding assemblies to rotate and control the two sets of rotating winding assemblies to rotate synchronously in opposite directions. This causes the steel wires released by the two sets of rotating winding assemblies to be interlaced and wound around the outer wall of the pipe in opposite spiral directions, thereby forming a mesh structure on the outer wall of the pipe. The eddy current heating component is installed on the discharge end side of the rotating winding component and is used to rapidly heat the steel wire wound on the outer wall through electromagnetic eddy current. The red-hot steel wire rope simultaneously heats and melts the pipe around the steel wire. The roller cooling component is installed on the discharge end side of the eddy current heating component. It is used to press the red-hot steel wire against the molten outer wall of the pipe, thereby pressing the steel wire into the outer wall of the pipe and cooling the red-hot steel wire, and causing the molten plastic on the outer wall of the pipe to solidify quickly, thereby fixing the steel wire rope into the solidified outer wall of the pipe.
