Description

Technical Field

[0001] The present invention relates to the field of electric wire production devices, and more particularly to an oil coating device for electric wire production by oil film coating and a method for using the same. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] In the production process of cables and wires, the adhesion of the cables is an important indicator of the performance of the cables. Whether it is between the conductor and the insulation layer, or between the cable core and the outer sheath, there must be a certain adhesion. For example, between the conductor and the insulation sheath, if the adhesion is too large, peeling will occur, and the adhesive will not adhere well to the conductor. If the adhesion is too small, the conductor will be easily pulled out, and the cable has weak load-bearing capacity. In order to control the adhesion, it is necessary to apply a sticky protective oil on the surface. The current outer protective layer oiling device for wire production has the following defects: The traditional outer protective layer oiling device for wire production is to evenly apply oil to the surface of the wire through a sponge. The sponge is used for oiling. Due to the limited oil absorption of the sponge, and only the oil attached to the surface of the sponge can be applied, the protective oil that has penetrated into the sponge cannot be used, which wastes resources. After the protective oil on the sponge is consumed, it needs to be replaced and re-absorbed, which is not easy to carry out the oiling work continuously, and the production efficiency is low. Summary of the invention

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide an oiling device for electric wire production by oil film coating, which can realize the application of protective oil to the cable before the fiber protective layer is braided into the cable, thereby easily improving the bonding tightness between the cable and the fiber protective layer, and at the same time covering the surface of the cable with the protective oil to prevent cable corrosion.

[0006] 2. Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] An oiling device for producing electric wires by oiling with an oil film, comprising an oiling device, the oiling device comprising a workbench, a shell fixedly connected to the workbench, a threading hole drilled on the shell, a fixed frame fixedly connected inside the shell, a tube shell fixedly connected to the fixed frame, an inner tube rotatably connected inside the tube shell, a plurality of oil grooves drilled on the inner tube, a plurality of evenly distributed oil injection holes drilled in the oil groove, an oiler fixedly connected to the fixed frame, the oiler comprising an oil injection pipe, an oil storage tank fixedly connected to the top of the oil injection pipe, the oil injection pipe communicates with the oil tank, and the A hydraulic piston is fixedly connected to the oil storage tank, a pair of driving mechanisms are fixedly connected in the shell, the driving mechanism includes a pair of movable arms, an electric push rod matching the movable arms is fixedly connected to the inner wall of the shell, a motor is fixedly connected to the movable arm, a driving wheel is fixedly connected to the motor, and a fiber layer weaving device is fixedly connected to the outer wall of the shell, which can realize the application of protective oil to the cable before the fiber protective layer is weaved, which is easy to improve the bonding tightness between the cable and the fiber protective layer, and at the same time the surface of the cable is covered with the protective oil to prevent the cable from corrosion.

[0009] Furthermore, one end of the fixed frame close to the driving mechanism is rotatably connected to a cable cleaning ring, and the cable cleaning ring includes a fixed ring, which is fixedly connected to the inner cylinder, a pair of semicircular scrapers are fixedly connected to the inner wall of the fixed ring, and a tooth groove is cut on the outer wall of the fixed ring. A servo motor is fixedly connected to the fixed frame, and a transmission gear matching the servo motor is fixedly connected to the power output end of the servo motor. The transmission gear is meshed with the fixed ring, so that the cable can be cleaned in a surrounding manner. At the same time, the cable cleaning ring drives the inner cylinder to rotate when it rotates, so that the oil on the semi-permeable membrane in the inner cylinder can be evenly applied to the cable.

[0010] Furthermore, a semi-permeable membrane is fixedly connected to the inner wall of the inner cylinder, and a plurality of evenly distributed adsorption sheets are fixedly connected to the semi-permeable membrane. The adsorption sheets are oil-absorbing sponges, so that the surface of the semi-permeable membrane can adsorb protective oil. An oil film on the semi-permeable membrane is formed by the protective oil that permeates the semi-permeable membrane and the protective oil adsorbed on the adsorption sheets, so that the cable is in contact with the oil film on the semi-permeable membrane for comprehensive oiling.

[0011] Furthermore, an oiling control system is provided, which includes a processor, the fiber layer weaving device, motor, servo motor and electric push rod are all connected to the processor signal, an infrared displacement sensor is fixedly connected to the output end of the shell, and the fiber layer weaving device is electrically connected to the processor and the infrared sensor.

[0012] Furthermore, the infrared displacement sensor records the length of the cable passing through the shell. Every time the infrared displacement sensor detects that the length of the cable passing through the shell reaches a set length, it sends a signal to the processor, so that the processor controls the hydraulic piston to replenish oil in the inner cylinder, thereby replenishing the protective oil in the hollow cylindrical cylinder in time, making it easy to carry out the oiling work continuously.

[0013] Furthermore, a distribution box is connected inside the workbench, and the processor, motor, servo motor and electric push rod are all electrically connected to the distribution box, which facilitates centralized power supply and distribution of the device.

[0014] Furthermore, the set length is: the technicians measured through experiments that, when the protective oil is not replenished, after the cable passes through the semi-permeable membrane on the inner cylinder, when a part of the cable that is not covered with protective oil appears, the length of the cable passing through the inner cylinder is the length of the cable passing through the inner cylinder. In this way, it is determined how much length of the cable can be oiled by the oil film on the semi-permeable membrane when the protective oil is not replenished, so that the processor can open the oiler in time to replenish the protective medicine of the device, which facilitates the continuous oiling work.

[0015] Furthermore, a plurality of thrust balls are connected between the tube shell and the inner tube, and annular grooves matching the thrust balls are bored on both the tube shell and the inner tube.

[0016] Further, the method of use is:

[0017] S1. The user controls the hydraulic piston to work, so that the protective oil in the oil storage tank is injected into the space between the tube shell and the inner tube through the oil injection pipe, and then flows to the semi-permeable membrane through the oil injection hole on the inner tube. The protective oil gradually passes through the semi-permeable membrane. The protective oil passing through the semi-permeable membrane is absorbed by the adsorption sheet. At this time, the cable is inserted into the shell, and the cable is driven into the tube shell by the driving mechanism;

[0018] S2, the cable is driven into the tube shell by the driving mechanism and contacts the inner cylinder in the shell, so that the surface of the cable is covered with oil attached to the semi-permeable membrane on the inner cylinder. When the cable enters the tube shell, the servo motor drives the transmission gear to rotate, so that the transmission gear drives the cable cleaning ring to clean the cable around, so that the sundries attached to the surface of the cable are scraped off;

[0019] S3, when the cable cleaning ring rotates, the inner cylinder is driven to rotate, so that the oil that penetrates the semi-permeable membrane and the protective oil adsorbed on the adsorption sheet rotate around the cable to apply oil to the cable. At the same time, during the application process, an oil film is formed on the semi-permeable membrane, so that the cable that subsequently enters the inner cylinder contacts with the oil film, so that the protective oil is applied to its surface.

[0020] 3. Beneficial effects

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] (1) This solution can apply protective oil to the cable before weaving the fiber protective layer, which is easy to improve the bonding tightness between the cable and the fiber protective layer, and at the same time, the surface of the cable is covered with the protective oil to prevent cable corrosion.

[0023] (2) This scheme passes the cable through a hollow cylinder so that the cable contacts the oil film on the semi-permeable membrane in the hollow cylinder, so that the surface of the cable is adhered to oil after passing through the hollow cylinder. This scheme also provides an oil storage tank and a hydraulic piston to inject protective oil into the hollow cylinder, and uses an infrared displacement sensor to record the length of the cable passing through the shell. Whenever the infrared displacement sensor detects that the length of the cable passing through the shell reaches a set length, it sends a signal to the processor, so that the processor controls the hydraulic piston to replenish oil in the inner cylinder, so that the protective oil in the hollow cylinder can be replenished in time, which facilitates the continuous oiling work.

[0024] (3) In this solution, a cable cleaning ring is provided on the tube shell. The cable cleaning ring rotates around the cable. The cable is cleaned by a semicircular scraper of the cable cleaning ring. At the same time, the inner tube is driven to rotate when the cable cleaning ring rotates, so that the oil on the semi-permeable membrane in the inner tube can be evenly applied to the cable.
