Description

Technical Field

[0001] This application relates to the technical field of composite pipe production and processing, and particularly relates to a wire lubricating device for composite pipes. Background Art

[0002] When producing composite pipes, a wire winding machine and an extruder need to be used in cooperation. The wire winding machine winds the wire on the wire reel around the side wall of the spring core. The wire is wound into a bent shape on the spring core, and then the extruder heats and melts the pipe wall material and pours it onto the wire to form a composite pipe.

[0003] When bending and winding the wire, the spring core rotates on the wire winding machine, and the wire continuously extends forward under the guidance of the spiral groove opened on the side wall of the spring core, forming the skeleton of the composite pipe. However, since the wire is wound too tightly on the spiral groove, the wire cannot continue to extend forward, and the staff needs to stop the machine to adjust the wire, which affects the processing efficiency of the composite pipe. Utility Model Content

[0004] In order to improve the processing efficiency of composite pipes, this application provides a wire lubricating device for composite pipes.

[0005] A wire lubricating device for composite pipes provided by this application adopts the following technical solutions:

[0006] A wire lubricating device for composite pipes includes an extruder, a wire winding machine, an annular heating mechanism, and a lubricating mechanism. The annular heating mechanism is fixedly arranged at the output end of the extruder, and the output end of the extruder is communicated with the inner cavity of the annular heating mechanism. The lubricating mechanism is fixedly arranged above the annular heating mechanism.

[0007] A spring core is coaxially rotatably arranged on the end face of the wire winding machine, and the spring core is arranged close to the annular heating mechanism. A spiral groove is opened on the circumferential side wall of the spring core, and a wire is wound in the spiral groove.

[0008] The lubricating mechanism is used to lubricate the spring core.

[0009] By adopting the above technical solution, the composite pipe steel wire lubrication device is set. When producing a composite pipe, the steel wire winding machine drives the spring winding core to rotate. The steel wire winding machine winds the steel wire around the side wall of the spring winding core. The steel wire bends on the spring winding core to form a spring shape. And while the steel wire winding machine rotates, the spring-shaped steel wire continuously extends forward in the spiral groove into the annular heating mechanism. At this time, the output end of the extruder extrudes the composite pipe base material. The base material is melted in the annular heating mechanism, and the melted base material is evenly poured on the spring-shaped steel wire. The steel wire and the base material are combined to form a composite pipe. While pouring, the lubrication mechanism sprays lubricating oil onto the spring winding core, reducing the friction between the steel wire and the spring winding core, facilitating the continuous forward extension of the spring-shaped steel wire, avoiding the steel wire from getting stuck in the spiral groove, and thus improving the production efficiency of the composite pipe.

[0010] In a specific feasible implementation, the lubrication mechanism includes an oil storage component, an oil injection component, an oil receiving component, and a circulation component. The oil storage component includes a lubricating oil tank and a tank support. The tank support is fixedly arranged on the side wall of the output end of the extruder, and the lubricating oil tank is fixedly connected to the tank support.

[0011] The oil injection component includes a drip tube and a flow valve. The drip tube is arranged at the bottom of the side wall of the lubricating oil tank, and one end of the drip tube communicates with the inner cavity of the lubricating oil tank. The other end of the drip tube faces the spiral groove. The flow valve is fixedly arranged at the end of the drip tube close to the lubricating oil tank.

[0012] The oil receiving component is fixedly arranged between the annular heating mechanism and the steel wire winding machine, and the circulation component is communicated with the oil receiving component.

[0013] By adopting the above technical solution, for the set lubrication device, the tank support limits and fixes the oil storage tank. During lubrication, the lubricating oil in the oil storage tube drips through the drip tube and is poured on the spiral groove, enabling lubrication to occur during the movement of the spiral groove and the steel wire, facilitating the avoidance of the steel wire getting stuck in the spiral groove, and thus improving the production efficiency of the composite pipe. At the same time, the flow valve can adjust the flow rate of the lubricating oil in the drip tube, facilitating the improvement of the lubrication quality.

[0014] In a specific feasible implementation, the drip tube is set as a universal joint tube.

[0015] By adopting the above technical solution, setting the drip tube as a universal joint tube facilitates changing the direction and angle of the drip tube, thereby facilitating the improvement of the accuracy of dripping oil from the drip tube onto the spiral groove and enhancing the lubrication effect on the steel wire in the spiral groove.

[0016] In a specific feasible implementation, the oil receiving assembly includes an oil receiving tank, and the oil receiving tank is fixedly installed on the side wall of the bracket of the wire winding spring machine. The oil receiving tank is located below the end of the drip oil pipe away from the lubricating oil tank;

[0017] A return oil hole is opened on the bottom wall of the oil receiving tank, and the circulation assembly is communicated with the return oil hole.

[0018] By adopting the above technical solution, the provided oil receiving assembly collects the lubricating oil dripped by the drip oil pipe during the process of dripping oil and lubricating the wire in the spiral groove, avoiding the pollution of the external environment by the lubricating oil.

[0019] In a specific feasible implementation, a filter screen is arranged on the return oil hole.

[0020] By adopting the above technical solution, the provided filter screen filters the lubricating oil in the oil receiving tank, avoiding the entry of sundries in the external environment into the oil receiving tank, causing the return oil hole to be blocked and resulting in poor oil flow.

[0021] In a specific feasible implementation, the circulation assembly includes a return oil pipe and a circulation pump. One end of the return oil pipe is communicated with the return oil hole, and the other end is fixedly arranged at the top of the side wall of the lubricating oil tank, and the return oil pipe is communicated with the inner cavity of the lubricating oil tank; the circulation pump is fixedly arranged on the return oil pipe.

[0022] By adopting the above technical solution, the provided circulation assembly, when the lubricating oil in the oil receiving tank accumulates to a certain amount, the lubricating oil in the oil receiving tank enters the return oil pipe, and the circulation pump pumps the lubricating oil in the return oil pipe into the lubricating oil tank for recycling and reuse of the lubricating oil, which is convenient for reducing production costs.

[0023] In a specific feasible implementation, an oil circuit control valve is arranged on the return oil pipe, and the oil circuit control valve is arranged between the circulation pump and the oil receiving tank.

[0024] By adopting the above technical solution, the provided oil circuit control valve, when the lubricating oil in the oil receiving tank accumulates to a certain quantity, the oil circuit control valve opens, the lubricating oil enters the return oil pipe, and the circulation pump pumps the lubricating oil, avoiding the continuous entry of the lubricating oil into the return oil pipe, resulting in frequent start and stop of the circulation pump, and being convenient for improving the service life of the circulation pump.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The provided composite tube wire lubrication device, the lubrication mechanism sprays lubricating oil onto the spring winding core, reducing the friction between the wire and the spring winding core, facilitating the continuous forward extension of the wire in the shape of a spring, avoiding the wire from being stuck in the spiral groove, and thus facilitating the improvement of the production efficiency of the composite tube.

[0027] 2. The provided circulation component. When the lubricating oil in the oil receiving tank accumulates to a certain amount, the lubricating oil in the oil receiving tank enters the return oil pipe, and the circulation pump pumps the lubricating oil in the return oil pipe into the lubricating oil tank for recycling and reuse of the lubricating oil, which helps to reduce production costs.

After the spring winding core 21 is lubricated, the remaining lubricating oil drips down into the oil receiving groove 431, and the oil receiving groove 431 collects the lubricating oil.
