Description

Technical Field

[0001] The invention relates to the technical field of oil coating devices, and in particular to a wire surface oil coating device. Background Art

[0002] When using an extruder to produce the outer sheath of a wire or cable, since the outer sheath of the wire or cable is made of rubber material, talcum powder is usually used for isolation to solve the problem of adhesion between the core wire and the outer sheath.

[0003] The use of talcum powder not only generates dust during the production process of wires, which pollutes the environment, but also affects the health of operators. One of the existing technologies is to use artificial oiling to replace the process of processing the outer sheath of wires with talcum powder, but artificial oiling has the problems of uneven oiling and low oiling efficiency.

[0004] Therefore, there is a need for a wire surface oiling device that can evenly coat the protective oil on the wire surface and has a high oiling efficiency. Summary of the invention

[0007] There is protective oil in the oil tank, and electric wires are arranged below the liquid level of the protective oil, that is, the electric wires are immersed below the liquid level of the protective oil. The surface of the electric wire is stained with protective oil, and the electric wire is extended into the drying device. The airflow inside the drying device flows through the surface of the electric wire, that is, the inside of the drying device blows air toward the surface of the electric wire, so that the protective oil is evenly covered on the surface of the electric wire, and a protective film is formed on the surface of the electric wire, thereby reducing the friction between the electric wire and other structures and extending the service life of the electric wire. The protective oil is evenly coated on the surface of the electric wire, so that the surface of the electric wire is clean and bright, and easy to peel, thereby improving production efficiency. Since the present invention does not need to use talcum powder, it can reduce pollution to the environment and avoid affecting the health of operators.

[0009] Through holes and drying devices are provided on both inner side walls of the oil tank, one of the through holes is connected to the wire inlet hole of the first drying device, and the other through hole is connected to the wire outlet hole of the second drying device. The wires pass through the wire inlet hole, pass through the protective oil, the protective oil is stained on the surface of the wires, and the wires pass through the wire outlet hole.

[0010] In a preferred technical solution of the present invention, the blow-drying device includes a blow-drying chamber, and a surface of the blow-drying chamber is provided with an inlet hole and an outlet hole along a first direction; the wires enter from the inlet hole and exit from the outlet hole, and the airflow in the blow-drying chamber flows through the wires.

[0011] The surface of the blow-drying chamber is provided with an inlet hole and an outlet hole along a first direction, the first direction is the direction of the line connecting the inlet hole and the outlet hole, and the first direction is parallel to the length direction of the oil tank. When the liquid level of the protective oil in the oil tank maintains a dynamic balance, that is, when the flow rate of the protective oil flowing into the oil tank is equal to the flow rate of the protective oil flowing out of the oil tank, the first direction is parallel to the liquid level of the protective oil.

[0012] In a preferred technical solution of the present invention, the blow-drying chamber is provided with an air inlet and an air outlet along the second direction; external air flows in from the air inlet and flows out from the air outlet to form the airflow.

[0013] The first direction is the same as the direction of the connection of the through holes on the two inner side walls of the oil tank, and the second direction is the height direction, that is, the air inlet and the air outlet are arranged along the height direction. After the external air flows into the drying chamber, the air is affected by gravity, so the flow rate of the air flow can be increased, the efficiency of drying the protective oil on the surface of the wire is improved, and a uniform protective film can be formed on the surface of the wire more quickly.

[0014] In a preferred technical solution of the present invention, an exhaust fan is arranged near the air inlet, and the exhaust fan is used to form a negative pressure in the drying chamber so that the external air flows into the air inlet.

[0015] By adjusting the power of the exhaust fan, the air pressure in the drying chamber can be changed, thereby changing the flow rate of the airflow in the drying chamber.

[0020] In a preferred technical solution of the present invention, the wire surface oiling device further comprises an oil storage tank, the oil storage tank is connected to the oil transfer tank, and the oil storage tank is used to supply oil to the oil transfer tank.

[0021] The protective oil flows from the oil storage tank into the oil tank to realize the recycling of the protective oil. When the liquid level of the protective oil in the oil storage tank is low, the protective oil is added to the oil storage tank.

[0025] After the motor is started, the protective oil is first pumped from the oil storage tank into the oil supply pipe. The protective oil in the oil supply pipe flows through the switch valve and enters the oil transfer tank. The protective oil in the oil transfer tank flows into the oil return pipe through the oil return port, and finally flows back from the oil return pipe to the oil storage tank. Repeat the above process, so that the protective oil circulates between the oil storage tank and the oil transfer tank.

[0026] In a preferred technical solution of the present invention, filter cotton is arranged near the wire outlet hole, the filter cotton is attached to one end of the wire passing through the wire outlet hole, and the filter cotton is used to absorb impurities in the protective oil on the surface of the wire.

Finally, the wire passing through the outlet hole extends out from the through hole on the inner wall of the oil tank. After the filter cotton absorbs a certain amount of impurities, its adsorption capacity will decrease. By regularly replacing the filter cotton, the filter cotton can continue to maintain an effective adsorption effect on the oiled wire surface.

Each drying device 3 is provided with a wire inlet hole 6 and a wire outlet hole 7.

[0047] The surface of the blow-drying chamber 5 is provided with an inlet hole 6 and an outlet hole 7 along a first direction, the first direction being the direction of the line connecting the inlet hole 6 and the outlet hole 7, and the first direction being parallel to the length direction of the oil-passing tank 1. When the liquid level of the protective oil 4 in the oil-passing tank 1 maintains a dynamic balance, that is, when the flow rate of the protective oil 4 flowing into the oil-passing tank 1 is equal to the flow rate of the protective oil 4 flowing out of the oil-passing tank 1, the first direction is parallel to the liquid level of the protective oil 4.

[0048] External air enters the drying chamber 5, and forms an airflow in the drying chamber 5. The airflow in the drying chamber 5 flows through the surface of the wire 2, and the protective oil 4 on the surface of the wire 2 flows in all directions under the action of wind force. After a period of time, the protective oil 4 is evenly distributed on the surface of the wire 2, thereby forming a protective film on the surface of the wire 2.

[0049] The two inner side walls of the oil-passing box 1 of this embodiment are both provided with a drying device 3, and the drying device 3 includes a drying chamber 5, and the surface of the drying chamber 5 is provided with a wire inlet hole 6 and a wire outlet hole 7 along a first direction.

After a period of time, the protective oil 4 is evenly distributed on the surface of the wire 2, thereby forming a protective film on the surface of the wire 2.

[0050] Example 3

[0051] like Figure 1-Figure 3 As shown, this embodiment provides a wire surface oiling device, including an oil passing tank 1, wherein a wire 2 is immersed below the oil surface in the oil passing tank 1; a blow-drying device 3 is provided on the inner side of the oil passing tank 1, and the wire 2 extends into the blow-drying device 3 and passes through the blow-drying device 3; the blow-drying device 3 blows air toward the wire 2 with the protective oil 4 on the surface, so as to evenly coat the protective oil 4 on the surface of the wire 2.

[0052] The blow-drying device 3 includes a blow-drying chamber 5, and a wire inlet hole 6 and a wire outlet hole 7 are opened on the surface of the blow-drying chamber 5 along a first direction; the wire 2 enters from the wire inlet hole 6 and exits from the wire outlet hole 7, and the airflow in the blow-drying chamber 5 flows through the wire 2.

[0053] The drying chamber 5 is provided with an air inlet 8 and an air outlet 9 along the second direction; external air flows in from the air inlet 8 and flows out from the air outlet 9 to form the airflow.

[0054] The first direction is the same as the direction of the line connecting the through holes on the two inner side walls of the oil tank 1, and the second direction is the height direction, that is, the air inlet 8 and the air outlet 9 are arranged along the height direction. Preferably, the air inlet 8 is arranged above the air outlet 9, and due to the different air pressures at different positions in the drying chamber 5, the air inlet 8 and the air outlet 9 form convection.

[0055] An air inlet 8 and an air outlet 9 are opened along the height direction. After the external air flows into the drying chamber 5, the air is affected by gravity, so the flow rate of the airflow can be increased, thereby improving the efficiency of drying the protective oil 4 on the surface of the wire 2, so that a uniform protective film can be formed on the surface of the wire 2 more quickly.

[0056] The surface of the drying chamber 5 is provided with a wire inlet hole 6, a wire outlet hole 7, an air inlet 8 and an air outlet 9 along two different directions, and the first direction and the second direction are perpendicular to each other, so that the structure of the drying chamber 5 can be fully utilized to dry the wire 2 stained with the protective oil 4 and then lead it out. The wire inlet hole 6 and the wire outlet hole 7 are arranged opposite to each other, so as to prevent the wire 2 from bending.

[0057] Preferably, a baffle is provided in the drying chamber 5, and the baffle is located between the air inlet 8 and the air outlet 9 to prevent the airflow from flowing directly out of the air outlet 9 after flowing in from the air inlet 8. The baffle is provided at a position close to the inlet hole 6, and the airflow bypasses the baffle after flowing into the air inlet 8. The airflow velocity near the baffle position is relatively slow, so as to extend the flow time of the airflow near the baffle position, so that the airflow is in full contact with the wire 2 stained with the protective oil 4, thereby improving the uniformity and consistency of the protective film formed by the protective oil 4 on the surface of the wire 2. The baffle can be provided at the midpoint of the line connecting the air inlet 8 and the air outlet 9, or it can be provided close to the air inlet 8 or the air outlet 9, which is not limited here.

An exhaust fan 10 is provided near the air inlet 8, and the exhaust fan 10 is used to form a negative pressure in the blow-drying chamber 5 so that external air flows into the air inlet 8. The air inlet 8 and the air outlet 9 are provided along the height direction, and after the external air flows into the blow-drying chamber 5, the air is affected by gravity, so the flow rate of the air flow can be increased, thereby improving the efficiency of drying the protective oil 4 on the surface of the wire 2, so that a uniform protective film can be formed on the surface of the wire 2 more quickly.

[0059] Example 4

[0060] like Figure 1-Figure 3As shown, this embodiment provides a wire surface oiling device, including an oil passing tank 1, wherein a wire 2 is immersed below the oil surface in the oil passing tank 1; a blow-drying device 3 is provided on the inner side of the oil passing tank 1, and the wire 2 extends into the blow-drying device 3 and passes through the blow-drying device 3; the blow-drying device 3 blows air toward the wire 2 with the protective oil 4 on the surface, so as to evenly coat the protective oil 4 on the surface of the wire 2.

[0061] The wire surface oiling device further comprises an oil storage tank 11 , which is connected to the oil transfer tank 1 , and is used to supply oil to the oil transfer tank 1 .

[0062] The oil storage tank 11 includes an oil outlet 12 and an oil return port 13, the oil outlet 12 is connected to a first end of an oil supply pipe 14, and a second end of the oil supply pipe 14 is connected to the oil transfer tank 1; the oil return port 13 is connected to a first end of an oil return pipe 15, and a second end of the oil return pipe 15 is connected to the oil transfer tank 1.

[0063] A switch valve 16 is provided at one end of the oil supply pipe 14 close to the oil transfer tank 1, and the switch valve 16 is used to control the opening and closing of the oil supply pipe 14; a motor 17 is provided at one end of the oil supply pipe 14 close to the oil storage tank 11, and the motor 17 is used to draw the protective oil 4 from the oil storage tank 11 into the oil transfer tank 1.

[0064] The switch valve 16 can control the oil supply speed in the oil supply pipe 14, and further control the amount of the protective oil 4 flowing from the oil storage tank 11 to the oil tank 1. Preferably, the switch valve 16 adjusts the flow rate by adjusting the throttle area between the valve core and the valve body and the local resistance generated by it, thereby controlling the flow rate of the protective oil 4. The oil supply speed can be controlled at any time by the switch valve 16. When producing 1mm 2 When producing wires 2 of smaller sizes, the valve of the switch valve 16 is opened to the middle position. When producing wires 2 of larger sizes, the valve of the switch valve 16 will be adjusted to the maximum to ensure sufficient oil volume.

[0065] Preferably, the switch valve 16 can be a speed regulating valve, which is used to control the flow rate of the protective oil 4 to adjust the working speed of the entire device. The speed regulating valve is usually composed of a valve body, a valve core and a spring. When the protective oil 4 passes through the speed regulating valve, the pressure of the protective oil 4 acts on the valve core. When the force of the spring is greater than the pressure of the protective oil 4, the valve core will be pushed in the closing direction and the flow rate will decrease; when the pressure of the protective oil 4 is greater than the force of the spring, the valve core will be pushed in the opening direction and the oil volume will increase. The speed regulating valve can maintain a stable flow rate through a built-in pressure compensation device, and is not affected by changes in the pressure difference between the oil outlet 12 and the oil return port 13, thereby accurately controlling the flow rate of the protective oil 4.

[0066] The switch valve 16 can also be a throttle valve, and the working principle of the throttle valve is to control the flow of the protective oil 4 by changing the throttle section or throttle length. Specifically, the cross-sectional area of ​​the medium channel is reduced, so that the flow of the protective oil 4 through the throttle port is reduced, the flow rate is accelerated, and the pressure is reduced, thereby realizing oil quantity regulation. By changing the size of the throttle throat or controlling the opening of the valve, the throttle valve can not only accurately adjust the flow and flow rate of the protective oil 4, but also has a wide adjustment range, which can meet the flow and flow rate control requirements under different working conditions. The structure of the throttle valve is also relatively simple, easy to manufacture and maintain, and low in cost.

[0067] After the motor 17 is started, the protective oil 4 is first drawn from the oil storage tank 11 into the oil supply pipe 14, and the protective oil 4 in the oil supply pipe 14 flows through the switch valve 16 and enters the oil tank 1. The protective oil 4 in the oil tank 1 flows into the return oil pipe 15 through the return oil port 13, and the protective oil 4 finally flows back to the oil storage tank 11 from the return oil pipe 15. The above process is repeated, so that the protective oil 4 circulates between the oil storage tank 11 and the oil tank 1. The present invention adopts a circulating oil passing method. The employee can add the protective oil 4 from the oil tank 1. By controlling the oil level in the oil tank 1, the excess protective oil 4 will flow back to the oil storage tank 11 from the return oil pipe 15. When the equipment alarms, the employee opens the valve of the switch valve 16, and the protective oil 4 will enter the oil tank 1 from the oil supply pipe 14 under the drive of the motor 17, forming a cyclic addition, ensuring the sufficiency and uniformity of the device when applying oil to the wire 2.

[0068] The wire surface oiling device of this embodiment also includes an oil storage tank 11, which is connected to the oil passing tank 1, and the oil storage tank 11 is used to supply oil to the oil passing tank 1. The oil storage tank 11 includes an oil outlet 12 and an oil return port 13, the oil outlet 12 is connected to the first end of the oil supply pipe 14, and the second end of the oil supply pipe 14 is connected to the oil passing tank 1; the oil return port 13 is connected to the first end of the oil return pipe 15, and the second end of the oil return pipe 15 is connected to the oil passing tank 1. The end of the oil supply pipe 14 close to the oil passing tank 1 is provided with a switch valve 16, and the switch valve 16 is used to control the opening and closing of the oil supply pipe 14; the end of the oil supply pipe 14 close to the oil storage tank 11 is provided with a motor 17, and the motor 17 is used to pump the protective oil 4 from the oil storage tank 11 into the oil passing tank 1. After the motor 17 is started, the protective oil 4 is first drawn from the oil storage tank 11 into the oil supply pipe 14, and the protective oil 4 in the oil supply pipe 14 flows through the switch valve 16 and enters the oil tank 1. The protective oil 4 in the oil tank 1 flows into the return oil pipe 15 through the return oil port 13, and the protective oil 4 finally flows back to the oil storage tank 11 from the return oil pipe 15. The above process is repeated, so that the protective oil 4 circulates between the oil storage tank 11 and the oil tank 1. The protective oil 4 in the oil storage tank 11 can always be at a controlled oil level, avoiding the waste of the protective oil 4 and greatly improving the efficiency of the oil supply. At the same time, the switch valve 16 in the oil supply pipe 14 can be used to control the flow rate and flow velocity of the protective oil 4 at any time. By adjusting the amount of oil supplied, the device can apply oil to wires 2 of different specifications and sizes, greatly improving the production efficiency of the oiling of the wires 2 and reducing the labor intensity of employees.

[0070] like Figure 1-Figure 3 As shown, this embodiment provides a wire surface oiling device, including an oil passing tank 1, wherein a wire 2 is immersed below the oil surface in the oil passing tank 1; a blow-drying device 3 is provided on the inner side of the oil passing tank 1, and the wire 2 extends into the blow-drying device 3 and passes through the blow-drying device 3; the blow-drying device 3 blows air toward the wire 2 with the protective oil 4 on the surface, so as to evenly coat the protective oil 4 on the surface of the wire 2.

[0071] The blow-drying device 3 includes a blow-drying chamber 5, and a wire inlet hole 6 and a wire outlet hole 7 are opened on the surface of the blow-drying chamber 5 along a first direction; the wire 2 enters from the wire inlet hole 6 and exits from the wire outlet hole 7, and the airflow in the blow-drying chamber 5 flows through the wire 2.

[0072] A filter cotton 18 is provided near the wire outlet hole 7 , and the filter cotton 18 is attached to one end of the wire 2 passing through the wire outlet hole 7 . The filter cotton 18 is used to absorb impurities in the protective oil 4 on the surface of the wire 2 .

[0073] According to the size of the wire 2, the wire inlet holes 6 and the wire outlet holes 7 of corresponding sizes are set, and the wire inlet holes 6 and the wire outlet holes 7 of the same sizes are arranged relatively to each other. Each group of wire inlet holes 6 and the wire outlet holes 7 of the same size can adapt to a specification of the wire 2, so that the wire 2 passes through the wire inlet holes 6 and the wire outlet holes 7 at the same time, ensuring that the wire 2 will not rub back and forth with the inner wall of the wire inlet hole 6 or the wire outlet hole 7 to cause the wire 2 to be scratched, so that the wire 2 can pass through the wire inlet hole 6 and the wire outlet hole 7 smoothly.

[0074] When the surface of the wire 2 is oiled, the wire 2 is first passed through the wire inlet hole 6, passed through the blow-drying chamber 5, and then passed through the wire outlet hole 7. The airflow in the blow-drying chamber 5 flows through the surface of the wire 2. Under the action of wind force, the protective oil 4 on the surface of the wire 2 flows in all directions until the protective oil 4 is evenly distributed on the surface of the wire 2, forming a protective film on the surface of the wire 2. The protective film protects the wire 2 and prevents it from sticking. When the wire 2 passes through the wire outlet hole 7, since there is a filter cotton 18 near the wire outlet hole 7, the filter cotton 18 can absorb impurities in the protective oil 4 on the surface of the wire 2, ensure the cleanliness of the surface of the wire 2, and further improve the oiling quality of the wire 2. Finally, the wire 2 passing through the wire outlet hole 7 extends out from the through hole on the inner wall of the oil tank 1. After the filter cotton 18 absorbs a certain amount of impurities, its adsorption capacity will decrease. By regularly replacing the filter cotton 18, the filter cotton 18 can continue to maintain an effective adsorption effect on the surface of the wire 2 after oiling.

[0075] The blow-drying device 3 of this embodiment includes a blow-drying chamber 5, and a wire inlet hole 6 and a wire outlet hole 7 are opened on the surface of the blow-drying chamber 5 along a first direction; the wire 2 passes through the wire inlet hole 6 and passes through the wire outlet hole 7, and the airflow in the blow-drying chamber 5 flows through the wire 2. A filter cotton 18 is arranged near the wire outlet hole 7, and the filter cotton 18 is attached to the end of the wire 2 passing through the wire outlet hole 7, and the filter cotton 18 is used to absorb impurities in the protective oil 4 on the surface of the wire 2. According to the size of the wire 2, the wire inlet hole 6 and the wire outlet hole 7 of corresponding size are arranged, and the wire inlet holes 6 and the wire outlet holes 7 of the same size are arranged relatively, and each group of wire inlet holes 6 and the wire outlet holes 7 of the same size can adapt to a specification of the wire 2, so that the wire 2 passes through the wire inlet hole 6 and the wire outlet hole 7 at the same time, ensuring that the wire 2 will not rub back and forth with the inner wall of the wire inlet hole 6 or the wire outlet hole 7 to cause the wire 2 to be scratched, so that the wire 2 can pass through the wire inlet hole 6 and the wire outlet hole 7 smoothly. After the protective oil 4 is applied, the wire 2 passes through the outlet hole 7 after the impurities are absorbed by the filter cotton 18, and then passes through the through hole on the side wall of the oil tank 1. The filter cotton 18 can absorb the impurities of the protective oil 4 on the surface of the wire 2, making the oiling effect better. Through the cooperation of the blow-drying chamber 5 and the filter cotton 18, the wire 2 can ensure the sufficiency and uniformity of the oiling during the oiling process, and can also ensure the quality of the oiling, which greatly improves the level of automatic oiling of the wire 2.
