Description

Technical Field

[0001] The present invention discloses a device for stably embedding resistance wires in reinforced polyethylene electric fusion pipe fittings, which relates to an embedding device for embedding resistance wires in reinforced polyethylene pipe sections to form reinforced polyethylene electric fusion pipe fittings. The device belongs to the technical field of water supply and drainage, and particularly relates to a device for stably embedding resistance wires in reinforced polyethylene pipe sections by hot-melting reinforced polyethylene pipe sections and supplementing hot-melt polyethylene raw materials between wire embedding molds and reinforced polyethylene pipe sections, so that the resistance wires and the inner wall of the reinforced polyethylene pipe sections are fully adhered, thereby enabling the resistance wires to be more stably embedded in the pipe sections without the occurrence of wire running. Background Art

[0002] The pipe is usually made of PE material, which has the advantage of strong corrosion resistance, but its rigidity and strength are always important issues faced by R&D personnel. At present, the usual way to solve the material problem of the pipe is to start from material research and development, which has a long R&D cycle and high comprehensive cost.

[0003] In order to improve the above problems, the applicant filed a Chinese utility model patent application with publication number CN210153353U and patent name "Wire Wrapped Tube". The wrapped tube improves the structure of the row tube based on the physical level, including: an inner tube extruded by the first hot melt extrusion, an outer tube extruded by the second hot melt extrusion, and a steel wire layer sandwiched between the inner tube and the outer tube. The rigidity and strength of the tube body are enhanced by internal reinforcement ribs, so that the tube body is not easy to deform along the axial direction, greatly reducing the deflection of the tube body along the axial direction, and also has better shear resistance. In actual use of pipes, multiple wire wrapped pipes need to be laid end to end in a groove to meet the drainage distance requirements. However, wire wrapped pipes cannot be directly hot-melt welded because of the steel wire wrapped inside the pipe wall. Therefore, polyethylene expansion hot-melt connection, polyethylene electric fusion pipe connection or rubber sealing ring connection are required for end to end connection. However, in the above connection methods, the connection part is made of pure polyethylene material and has a low pressure bearing capacity. The pressure bearing capacity of the connected wire wrapped pipe is lower than the pressure bearing capacity of the wire wrapped pipe itself. If the pressure bearing capacity of the wire wrapped pipe itself is used for water supply and drainage, it is easy to cause the connection to be subjected to excessive pressure and rupture. If the pressure bearing capacity of the connection is used for water supply and drainage, it will cause a waste of drainage capacity of a large section of wire wrapped pipe.

[0004] In order to improve the above problems, the applicant filed another Chinese invention patent application entitled "A Reinforced Polyethylene Electric Fusion Pipe Fitting and Processing Method", which uses a cutting knife to open a spiral groove on the inner wall of the reinforced polyethylene pipe section, and at the same time bury the resistance wire in the groove, and bury the resistance wire by extrusion to form a reinforced polyethylene electric fusion pipe fitting. By connecting multiple steel wire winding pipes through the reinforced polyethylene electric fusion pipe fitting, the pressure bearing capacity of the connection can be effectively improved to keep it consistent with the steel wire winding pipe. However, in the processing method of cutting grooves and burying resistance wires, during the wire burying process, the resistance wire is easy to fall off or deviate from the groove, resulting in wire running, which affects the quality of the electric fusion pipe fitting. Summary of the invention

[0005] In order to improve the above situation, the present invention provides a device for stably embedding resistance wires in reinforced polyethylene electric fusion pipe fittings. The device provides a device for stably embedding resistance wires by heating the resistance wires electrically to melt the inner wall of the reinforced polyethylene pipe section, and then adding hot-melt polyethylene raw materials between the wire embedding mold and the reinforced polyethylene pipe section, so that the resistance wires and the inner wall of the reinforced polyethylene pipe section are fully adhered. The resistance wires and the inner wall of the reinforced polyethylene pipe section are adhered, and after cooling, the resistance wires can be more stably embedded in the pipe section without wire running. In the process of adding hot-melt polyethylene raw materials, the wire embedding mold and the resistance wire are driven to rotate slowly by a rotating motor, so that the added hot-melt polyethylene raw materials can be evenly distributed between the wire mold and the reinforced polyethylene pipe section, ensuring that the inner diameter of the pipe section after the resistance wires are embedded meets the requirements.

[0014] The difference between this embodiment and embodiment 2 is that: the reinforced polyethylene pipe section support ring (6) is provided with anti-slip grooves (17), the anti-slip grooves (17) are cross-twill grooves, and the anti-slip grooves (17) are located between the inner ring of the reinforced polyethylene pipe section support ring (6) and the reinforced polyethylene pipe section limit plate (7); when in use, the anti-slip grooves (17) can make the placement of the reinforced polyethylene pipe section more stable, and cooperate with the clamping force of the limit bolts (8) to effectively prevent the reinforced polyethylene pipe section from sliding with the rotation of the wire embedding mold (5), thereby affecting the quality of the wire embedding; The limiting bolt (8) is designed to limit the position of the reinforced polyethylene pipe segment in cooperation with the limiting plate (7) of the reinforced polyethylene pipe segment.

The plurality of rotation limiting columns (15) are arranged equidistantly along the circumference of the mold support plate (14) and are located at the edge of the mold support plate (14), so as to form a relatively smooth support for the edge of the mold support plate (14), thereby preventing the edge of the mold support plate (14) from deviating up and down during the uniform rotation, thereby ensuring the stable rotation of the wire embedding mold (5) and further ensuring the stability of the wire embedding; The mold support plate (14) is provided with a plurality of engaging grooves, and one end of the wire embedding mold (5) is provided with engaging columns corresponding to the plurality of engaging grooves. The wire embedding mold (5) is detachably placed on the mold support plate (14) by means of the engaging columns cooperating with the engaging grooves. The wire embedding mold (5) is detachable and can be removed together with the reinforced polyethylene pipe section after the wire is embedded and then removed from the mold after cooling. The wire embedding and cooling are performed simultaneously, which is highly efficient. The height of the reinforced polyethylene pipe section support ring (6) is higher than the height of the mold support plate (14), and the sealing bearing can prevent the hot-melt polyethylene raw material from flowing down and entering between the mold support plate (14) and the wire embedding mold (5), thereby ensuring the stability of the wire embedding; The purpose is to achieve the purpose of being able to melt the inner wall of the reinforced polyethylene pipe section by heating the resistance wire (9) with electricity, and then adding hot-melt polyethylene raw material between the wire embedding mold (5) and the reinforced polyethylene pipe section, so that the resistance wire (9) and the inner wall of the reinforced polyethylene pipe section are fully adhered, and after cooling, the resistance wire (9) can be embedded in the pipe section more stably without the occurrence of wire running.
