Description

Technical Field

[0001] This application belongs to the technical field of pipe production, and particularly relates to a composite pipe production device and its production process. Background Art

[0002] Plastic pipes are chemical building materials made by high-tech composites. Due to advantages such as small water flow loss, energy conservation, material conservation, environmental protection, and convenient completion, they are currently widely used in water supply and drainage and gas pipelines. The steel wire mesh skeleton plastic composite pipe is a high-end product among plastic pipes. It uses a mesh structure formed by winding high-strength copper-plated steel wires around left and right as the skeleton and high-density plastic as the matrix material.

[0003] However, during the process of forming the existing steel wire into a mesh, the resin layer is prone to falling off, which easily leads to an unstable structure of the steel wire mesh. Summary of the Invention

[0004] The purpose of this application is to address the above-mentioned existing technical problems by providing a composite pipe production device to improve the structural stability of copper-plated steel wires and ensure that the steel wires are not easily detached during the production of the outer layer of the pipe.

[0005] This application provides a composite pipe production device, including:

[0006] A first extruder, provided with an inner layer die;

[0007] A first vacuum sizing tank, used for sizing the inner layer of the pipe;

[0008] A traction device, used for pulling the inner layer of the pipe to move;

[0009] A first winding machine, used for winding copper-plated steel wires around the outer surface of the inner layer of the pipe;

[0010] A first heating device, used for heating the copper-plated steel wires. The first heating device is provided with an induction coil;

[0011] A second extruder, provided with an outer layer die;

[0012] A second vacuum sizing tank, used for sizing the outer layer of the pipe;

[0013] A cooling device, used for cooling the composite pipe;

[0014] A cutting device, used for cutting the composite pipe.

[0015] The inner layer of the pipe is formed by the first extruder and the first vacuum sizing box. The inner layer of the pipe is traction-moved by the traction device to ensure the moving speed of the pipe and make the winding of the first winding machine uniform. The copper-plated steel wire is wound on the outer surface of the inner layer of the pipe by the first winding machine, and the copper-plated steel wire is wound in a spiral shape. The inductance coil heats the copper-plated steel wire by energizing the first heating device. The copper-plated steel wire is wound on the inner layer of the pipe. When the copper-plated steel wire is heated, the positions where the inner layer of the pipe and the copper-plated steel wire are in contact are bonded to improve the connection stability between the copper-plated steel wire and the inner layer of the pipe. When the inner layer of the pipe passes through the second extruder, the high temperature of the outer layer of the pipe ensures the structural stability between the copper-plated steel wire and the inner layer of the pipe. The outer layer of the pipe is formed by the second extruder and the second vacuum sizing box, and then cooled by the cooling device and cut by the cutting device to process the composite pipe. The copper-plated steel wire is stably distributed to ensure the structural stability of the composite pipe.

[0016] Further, it further includes:

[0017] A second winding machine for winding the copper-plated steel wire on the outer surface of the inner layer of the pipe;

[0019] Among them, the second heating device has the same structure as the first heating device, and the winding direction of the second winding machine is opposite to that of the first winding machine.

[0020] The copper-plated steel wire is wound onto the outer wall surface of the inner layer of the pipe by the second winding machine. The winding direction of the second winding machine is opposite to that of the first winding machine, so that the two layers of copper-plated steel wire present a mesh structure, further improving the structural strength of the composite pipe after forming. The copper-plated steel wire with opposite winding directions is bonded at the staggered nodes by the second heating device to improve the structural strength of the copper-plated steel wire woven into a mesh.

[0021] Further, the first winding machine and the second winding machine are provided with a number of spindles, and the winding groups wound with the copper-plated steel wire are placed on the spindles.

[0022] The copper-plated steel wire coil winding group is placed on the spindle to ensure the stability of the copper-plated steel wire unwinding and can stably wind the copper-plated steel wire on the inner layer of the pipe. The spindles are distributed circumferentially around the first winding machine and the second winding machine.

[0023] Further, the traction device includes:

[0024] Traction seats placed on the upper and lower sides of the pipe;

[0025] A cylinder for driving the traction seat to move;

[0026] A conveyor chain movably installed on the traction seat;

[0028] The driving device is used to drive the conveyor chain to rotate.

[0029] The traction seat is driven to move by a cylinder, which is used to adjust the position of the traction seat to facilitate adapting to the production and processing of pipes with different diameters. The conveyor chain installed on the traction seat is driven to rotate by the driving device. The traction block is installed on the conveyor chain. When the conveyor chain rotates, the traction block moves, and the traction blocks on both the upper and lower sides of the pipe clamp the pipe, causing the pipe to move with the traction block.

[0030] Furthermore, the traction block includes:

[0031] The V-shaped surface is adapted to the outer wall surface of the pipe;

[0032] The installation groove is placed in the V-shaped surface;

[0033] The adsorbent is installed in the installation groove, and the adsorbent is provided with a telescopic structure;

[0034] The air vent switch is installed on the traction block;

[0035] Wherein, the adsorbent is provided with an adsorption cavity, the adsorption cavity is installed and connected with the air vent switch, and the adsorbent is provided with a flange.

[0036] When the traction block pulls the pipe, the pipe is adsorbed by the adsorbent, improving the stability between the traction block and the pipe, making it not easy for the traction block to slip with the pipe when moving. The V-shaped surface is adapted to the pipe, the adsorbent is installed in the installation groove, and the seal between the adsorbent and the pipe is increased through the flange. The adsorbent discharges the gas inside the adsorption cavity through the telescopic structure to realize the adsorption of the adsorbent to the pipe. The air inlet and outlet in the adsorbent are controlled by the air vent switch, and the air vent switch controls the release of the adsorption effect between the adsorbent and the pipe.

[0037] Furthermore, the telescopic structure includes:

[0038] The corrugated pipe;

[0039] The installation ring is installed at the peak of the corrugated pipe;

[0040] The installation block is installed at the trough of the corrugated pipe;

[0042] Wherein, the connecting rod is hinged with the installation ring and the installation block.

[0043] The telescopic performance of the adsorbing part is realized through the corrugated pipe. The telescopic structure can only be telescoped along the axial direction through the mounting ring, mounting block, and connecting rod. There are at least 3 or more connecting rods. Connect the mounting ring to the second mounting. When the adsorbing part adsorbs on the pipeline, the axis of the telescopic structure is perpendicular to the outer surface of the pipeline.

[0044] Furthermore, the ventilation switch includes:

[0045] A switch seat provided with a sliding part;

[0046] A ball joint seat adapted to the switch seat and provided with a first through hole communicating with the adsorption cavity;

[0047] A button placed on the traction block and abutted against the switch seat;

[0048] A first spring placed between the sliding part and the traction block;

[0052] The convex block is installed at one end of the traction block where the pipeline is just clamped. When the traction block moves to the position of the convex block, the convex block acts on the button, presses the button into the traction block, makes the switch seat move, and the movement of the switch seat compresses the telescopic structure to discharge the air in the adsorption cavity through the first through hole and the one-way valve plate. When the button is separated from the convex block, the switch seat makes the telescopic structure extend under the action of the second spring, making the air pressure in the adsorption cavity less than the atmospheric pressure, realizing the adsorption of the adsorbing part on the pipeline. When the traction block is separated from the pipeline, the adsorbing part rotates between the ball joint seat and the switch seat, making the first through hole correspond to the second through hole, releasing the adsorption between the adsorbing part and the pipeline. The sliding of the switch seat is facilitated through the sliding part and the chute, and the adsorbing part is telescoped into the installation groove through the first spring.

[0053] This application also provides a production process for a composite pipeline production device, including the following process steps:

[0054] S1, Prepare materials, including polyethylene particles, black masterbatch particles, and copper-plated steel wires;

[0055] S2, Add polyethylene particles to the first extruder. After melting and extruding the polyethylene particles, pass them through the inner layer die, and then cool and form in the first vacuum shaping box to obtain a white pipeline inner layer;

[0056] S3, the inner layer of the pipeline is pulled to move by a pulling device, and then the copper-plated steel wire is wound on the inner layer of the pipeline by a first winding machine, and the first heating device is energized so that the inductance coil heats the copper-plated steel wire, and the heated copper-plated steel wire is bonded to the position where it abuts against the outer wall surface of the inner layer of the pipeline;

[0057] S4, then winding the copper-plated steel wire on the inner layer of the pipe through the second winding machine, so that the two layers of copper-plated steel wire are wound into a mesh shape, and the second heating device is energized so that the inductor coil heats the copper-plated steel wire, and the heated copper-plated steel wires are bonded to each other at the staggered nodes;

[0058] S5, adding polyethylene particles and black masterbatch particles in the second extruder, passing through an outer layer mold after melt extrusion, and then cooling and molding in a second vacuum setting box to obtain a black outer layer of the pipeline;

[0059] S6, after being cooled by the cooling device, the cutting device cuts the composite pipe into a specified length.

[0060] The beneficial effects of this application are:

[0061] 1. The inner layer of the pipeline is pulled and moved by a traction device to ensure the moving speed of the pipeline, so that the winding of the first winding machine is uniform. The copper-plated steel wire is wound on the outer surface of the inner layer of the pipeline by the first winding machine, so that the copper-plated steel wire is wound in a spiral shape. The copper-plated steel wire is wound on the outer wall surface of the inner layer of the pipeline by the second winding machine. The winding direction of the second winding machine is opposite to that of the first winding machine, so that the two layers of copper-plated steel wire present a mesh structure.

[0062] 2. The traction seat is driven to move by a cylinder to adjust the position of the traction seat to adapt to the production and processing of pipes with different diameters. The conveyor chain is driven to rotate by the driving device, and the traction block moves. The adsorption piece is adsorbed on the pipe to improve the stability between the traction block and the pipe, so that the traction block is not easy to slip on the pipe when moving.

[0063] 3. The telescopic performance of the adsorbent is achieved through the bellows. The telescopic structure is controlled to be able to telescope only along the axial direction through the mounting ring, mounting block and connecting rod. When the adsorbent is adsorbed to the pipe, the axis of the telescopic structure is perpendicular to the outer surface of the pipe.

[0064] 4. After the protruding block acts on the button, it separates from the button, and discharges the air in the adsorption chamber through the first through hole and the one-way valve plate, so that the air pressure in the adsorption chamber is less than the atmospheric pressure, so that the adsorption member adsorbs the pipeline. When the traction block is separated from the pipeline, the adsorption member rotates between the ball joint seat and the switch seat, so that the first through hole corresponds to the second through hole, and the adsorption between the adsorption member and the pipeline is released.
