Description

Technical Field

[0001] This invention relates to a device for stabilizing the embedding of resistance wire into reinforced polyethylene electrofusion pipe fittings. It is a device for embedding resistance wire into reinforced polyethylene pipe sections to form reinforced polyethylene electrofusion pipe fittings, belonging to the field of water supply and drainage technology. Specifically, it relates to a device that uses hot-melt reinforced polyethylene pipe sections and supplements the embedding mold and reinforced polyethylene pipe sections with hot-melt polyethylene material, ensuring sufficient adhesion between the resistance wire and the inner wall of the reinforced polyethylene pipe section. This allows the resistance wire to be more stably embedded in the pipe section without wire slippage. Background Technology

[0002] Piping systems are typically made of PE material, which offers advantages such as strong corrosion resistance. However, its rigidity and strength remain significant challenges for researchers. Currently, the common approach to addressing the material requirements of piping systems is to focus on material development, which involves long development cycles and high overall costs.

[0003] To address the aforementioned issues, the applicant filed a Chinese utility model patent application with publication number CN210153353U, entitled "Steel Wire Winding Pipe." This winding pipe improves the structure of the pipe arrangement at a physical level, comprising: an inner tube formed by initial hot-melt extrusion, an outer tube formed by secondary hot-melt extrusion, and a steel wire layer sandwiched between the inner and outer tubes. The internal reinforcing ribs enhance the rigidity and strength of the pipe body, making it less prone to axial deformation, greatly reducing the axial deflection of the pipe body, and also providing better shear resistance. In practical applications, multiple wire-wound pipes need to be laid end-to-end in a trench to meet drainage distance requirements. However, because the wire-wound pipes have steel wires wrapped inside their walls, they cannot be directly heat-fused and welded. Therefore, methods such as polyethylene flared heat fusion connection, polyethylene electrofusion fitting connection, or rubber sealing ring connection are required for end-to-end connection. However, with these connection methods, the joint is made of pure polyethylene material, which has low pressure resistance. The pressure resistance of the joint after connection is lower than that of the wire-wound pipe itself. If the water supply is based on the pressure resistance of the wire-wound pipe itself, it is easy to cause the joint to be subjected to excessive pressure and break. If the water supply is based on the pressure resistance of the joint, it will result in a waste of the drainage capacity of a large section of wire-wound pipe.

[0004] To address the aforementioned issues, the applicant filed a separate Chinese invention patent application entitled "A Reinforced Polyethylene Electrofusion Fitting and Processing Method." This method involves creating spiral grooves on the inner wall of a reinforced polyethylene pipe section using a cutter, embedding resistance wires within the grooves, and then pressing the resistance wires to form a reinforced polyethylene electrofusion fitting. Connecting multiple wire-wound pipes with this fitting effectively improves the pressure-bearing capacity at the connection point, ensuring consistency with the wire-wound pipes. However, this groove-cutting and wire-embedding processing method is prone to the resistance wires detaching or shifting from the grooves during the embedding process, resulting in wire slippage and affecting the quality of the electrofusion fitting. Summary of the Invention

[0005] To improve upon the above situation, the present invention provides a device for the stable embedding of resistance wire in reinforced polyethylene electrofusion pipe fittings. This device involves heating the resistance wire with electricity to melt the inner wall of the reinforced polyethylene pipe section, then adding hot-melt polyethylene material between the embedding mold and the reinforced polyethylene pipe section, ensuring a thorough adhesion between the resistance wire and the inner wall of the reinforced polyethylene pipe section. This adhesion allows the resistance wire to be more stably embedded in the pipe section after cooling, preventing wire slippage. During the addition of hot-melt polyethylene material, a rotary motor drives the embedding mold and resistance wire to rotate slowly, ensuring uniform distribution of the added hot-melt polyethylene material between the mold and the reinforced polyethylene pipe section, guaranteeing that the inner diameter of the pipe section after embedding the resistance wire meets the requirements.

[0060] Preferably, a sealed bearing is provided between the motor shaft of the rotary motor (12) and the wall of the wire embedding worktable (4).

[0061] The mold support plate (14) is placed on the motor shaft of the rotary motor (12), and there is a distance between it and the wire embedding worktable (4).

[0062] Multiple rotating limiting posts (15) are placed between the mold support plate (14) and the wire embedding worktable (4). One end of each rotating limiting post (15) is connected to the wire embedding worktable (4), and the other end of each rotating limiting post (15) is provided with a rotating ball. The rotating ball is in contact with the mold support plate (14).

[0063] Preferably, the plurality of rotation limiting posts (15) are arranged at equal intervals along the circumference of the mold support plate (14) and are located at the edge of the mold support plate (14).

[0074] The reinforced polyethylene pipe section limiting plate (7) has threaded holes, and the limiting bolt (8) is threadedly connected to the reinforced polyethylene pipe section limiting plate (7) through the threaded holes.

[0075] Preferably, a rubber pad is provided at the end of the limiting bolt (8);

[0076] In use, connect the hot melt polyethylene conveying pipe (1) and the hot melt high-pressure conveyor. Place the reinforced polyethylene pipe section on the reinforced polyethylene pipe section support ring (6). The outer wall of the reinforced polyethylene pipe section is tightly attached to the reinforced polyethylene pipe section limiting plate (7), and the inner wall is tightly attached to the resistance wire (9). Rotate the limiting bolt (8) to support and clamp the reinforced polyethylene pipe section. Turn on the resistance wire (9) to heat it up, which heats the embedded wire mold (5) and the inner wall of the reinforced polyethylene pipe section, causing the inner wall of the reinforced polyethylene pipe section to melt. Turn off the power and start the rotary motor (12). The rotary motor (12) drives the mold support plate (14) to rotate slowly and uniformly through the motor shaft, which in turn drives the embedded wire mold (5) and the resistance wire (9) to rotate slowly. Rotate at a constant speed, and at the same time, hot melt polyethylene raw material is added between the embedded wire mold (5) and the reinforced polyethylene pipe section through the hot melt polyethylene conveying pipe (1). During the rotation, the hot melt polyethylene raw material is evenly distributed between the embedded wire mold (5) and the inner wall of the pipe section, and fully adheres to the molten layer of the inner wall of the pipe section to avoid delamination. At the same time, the resistance wire (9) is also gradually embedded into the molten layer of the inner wall of the reinforced polyethylene pipe section. After the raw material is added, control the rotating motor (12) to stop, loosen the limit bolt (8), and take down the reinforced polyethylene pipe section and the embedded wire mold (5) together and place them in the cooling area to wait for cooling. After the cooling is completed, take down the embedded wire mold (5), and the resistance wire (9) is stably embedded in the reinforced polyethylene pipe section. Example 2

[0077] The difference between this embodiment and embodiment 1 is that: the reinforced polyethylene pipe section support ring (6) has a resistance wire routing groove (16), there are multiple resistance wire routing grooves (16), the multiple resistance wire routing grooves (16) are arranged at equal intervals along the circumference of the reinforced polyethylene pipe section support ring (6), one end of the resistance wire routing groove (16) is flush with the inner ring surface of the reinforced polyethylene pipe section support ring (6), and the other end of the resistance wire routing groove (16) is flush with the outer ring surface of the reinforced polyethylene pipe section support ring (6); in use, the resistance wire routing groove (16) enables the resistance wire (9) to run smoothly and stably on the reinforced polyethylene pipe section support ring (6) for heating, while ensuring that the placement stability of the reinforced polyethylene pipe section is not affected when the resistance wire (9) is running; Example 3

[0078] The difference between this embodiment and embodiment 2 is that: the reinforced polyethylene pipe section support ring (6) has anti-slip texture (17), the anti-slip texture (17) is a cross diagonal texture, and the anti-slip texture (17) is located between the inner ring of the reinforced polyethylene pipe section support ring (6) and the reinforced polyethylene pipe section limiting plate (7); when in use, the anti-slip texture (17) can make the placement of the reinforced polyethylene pipe section more stable, and with the clamping force of the limiting bolt (8), it can effectively prevent the reinforced polyethylene pipe section from sliding with the rotation of the wire embedding mold (5) and affecting the wire embedding quality;

[0079] The limiting bolt (8) is designed to limit the reinforced polyethylene pipe section in conjunction with the reinforcing polyethylene pipe section limiting plate (7). By accurately positioning the reinforced polyethylene pipe section, the uniform distance between each part of the pipe section and the embedded wire mold (5) is achieved, avoiding the thickness difference between different parts of the pipe section when hot melt polyethylene raw material is added, which affects the embedding quality of the resistance wire (9).

[0080] The design of the rubber pad at the end of the limiting bolt (8) can prevent the limiting bolt (8) from causing hard extrusion and scratches on the reinforced polyethylene pipe section during the process of supporting and clamping the reinforced polyethylene pipe section, thus affecting the overall strength of the reinforced polyethylene electrofusion pipe fitting after molding.

[0081] The design of the conveying pipe support rod (10) and the conveying pipe limiter (11) to support the hot melt polyethylene conveying pipe (1) is as follows: the hot melt polyethylene will vibrate during the high pressure conveying process. The limiter fixes the hot melt polyethylene conveying pipe (1) on the conveying pipe support rod (10), which can provide stable support for the conveying pipe and ensure stable and uniform injection of hot melt polyethylene.

[0082] The multiple rotating limit pins (15) are arranged at equal intervals along the circumference of the mold support plate (14) and are located at the edge of the mold support plate (14). This design can provide relatively smooth support to the edge of the mold support plate (14), prevent the edge of the mold support plate (14) from deviating vertically during uniform rotation, ensure the stable rotation of the embedded wire mold (5), and thus ensure the stability of the embedded wire.

[0083] The mold support plate (14) has multiple locking grooves. One end of the wire embedding mold (5) is provided with a locking post corresponding to the multiple locking grooves. The wire embedding mold (5) is designed to be detachably placed on the mold support plate (14) through the locking post and locking groove. The wire embedding mold (5) is detachable and can be removed together with the reinforced polyethylene pipe section after wire embedding, and then removed after cooling. Wire embedding and cooling are carried out at the same time, which is highly efficient.

[0084] The design of the height of the reinforced polyethylene pipe section support ring (6) being higher than the height of the mold support plate (14) can prevent the hot melt polyethylene raw material from flowing down into the space between the mold support plate (14) and the embedded wire mold (5) through the sealed bearing, thus ensuring the stability of the embedded wire.

[0085] The goal is to achieve the following: after heating the resistance wire (9) with electricity to melt the inner wall of the reinforced polyethylene pipe section, hot melt polyethylene raw material is added between the embedded wire 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 bonded. After cooling, the resistance wire (9) can be more stably embedded in the pipe section without the phenomenon of wire running away.

[0086] It should be noted that, unless otherwise explicitly specified and limited, the terms "placed," "connected," and "linked" should be interpreted broadly. For example, they can refer to fixed connections such as folded edges, rivets, pins, adhesives, and welds; detachable connections such as threaded connections, snap-fit ​​connections, and hinges; integral connections; electrical connections; direct connections; or indirect connections via an intermediate medium; or internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0087] It should be further noted that, in order to keep the description simple and clear, the above specific embodiments only describe the differences between them and other embodiments. However, those skilled in the art should know that the above specific embodiments are also independent technical solutions.
