Description

Technical Field

[0001] The present invention relates to the technical field of wire and cable production equipment, and in particular to an oiling process for wire and cable production. Background Art

[0002] Cables are made of one or more mutually insulated conductors surrounded by an insulating protective layer. They transmit electricity or information from one location to another. During the production process, cables need to be lubricated to improve insulation, flame resistance, and other essential properties. The oiler is the equipment for lubricating cables, which primarily consists of a guide pulley and an oil tank. During oiling, the cable passes through the oiler body, where it is guided by three guide pulleys to complete the oiling process. After oiling, the cable is reeled in by a reeling mechanism.

[0003] In the existing technology, the cables directly enter the interior of the oiler body during oiling. In order to ensure the oiling efficiency, the wires and cables are in a continuous conveying state during the contact with the oil, which cannot ensure the oiling effect of the cables, resulting in insufficient and uneven oiling of the wires and cables. On the other hand, the wires and cables after oiling are directly reeled in by the reeling mechanism, and the excess oil on the cables needs to be manually handled by the staff. The oil dripping from the cable outlet of the oiler cannot be recovered, which can easily cause pollution to the working area. Summary of the Invention

[0017] Compared with the prior art, the present invention provides an oil-passing process for the production of wires and cables, which has the following beneficial effects:

[0018] 1. This oiling process for wire and cable production uses the cooperation of the auger and the extrusion assembly. Regardless of the size of the gap between the pressing plate and the auger, the pressing plate is always pressed against the wire and cable, thereby ensuring that the wire and cable can always be in contact with the rubber particles and a certain extrusion force is generated, thereby ensuring that the cable is fully and evenly oiled during the processing process;

[0020] 3. The oil-passing process for wire and cable production provides a tensioning assembly during the cleaning process after oil discharge. Since the first guide wheel is elastically connected and slidably connected to the bottom of the cross plate by a spring, the cable can maintain a stretching and tensioning effect when it fits the bottom of the first guide wheel, which can better ensure the oil cleaning effect during cleaning.

[0021] 4.

When the oil in the oil receiving box reaches a certain volume, the pump body is started to pump the oil in the oil receiving box into the oil storage tank in time to replenish the oil.

[0022] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The present invention can ensure that the wires and cables can always be in contact with the rubber particles and generate a certain extrusion pressure, thereby ensuring that the cables are fully and evenly oiled during the processing process; automatically change the distance between two adjacent groups of rollers to perform secondary cleaning of the oil on the surface of the cable; maintain the stretching and tensioning effect, and better ensure the oil cleaning effect during cleaning; the oil received in the oil receiving box can be pumped into the oil storage tank in time to replenish the oil.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0032] Example:

[0033] Reference Figures 1-6, an oil-passing process for the production of wires and cables, including an electrical cabinet 1 and an oil tank 2 fixedly connected to the top of the electrical cabinet 1, the oil tank 2 is connected to an oil storage tank 5, the oil storage tank 5 is connected to the top of the oil tank 2 through a support rod 4, and an oil pipe 7 is connected between the oil storage tank 5 and the oil tank 2, and a flow meter is provided in the oil pipe 7.

[0034] In this embodiment, a PLC control system is provided in the electrical cabinet 1, which controls the oil storage tank 5 to supply oil to the oil tank 2. A flow meter is provided between the oil storage tank 5 and the oil pipe 7 to monitor the oil amount in the oil storage tank 5 and supply oil to the oil tank 2 in a timely manner as needed.

[0035] A cable introduction wheel 3 is provided on the outer wall of the oil tank 2 at the inlet position of the wires and cables, and the surface of the cable introduction wheel 3 is wrapped with a rubber sheet.

[0036] In this embodiment, a cable introduction wheel 3 is provided at the entrance of the outer wall of the oil tank 2 to introduce the wires and cables for transportation. The surface of the cable introduction wheel 3 includes a rubber plate, which is used to reduce the friction between the cable introduction wheel 3 and the wires and cables to avoid damage to the wires and cables during transportation.

[0037] This embodiment also includes a guide assembly fixedly installed inside the oil tank 2, the guide assembly includes an oil trough 11 arranged in the oil tank 2 and an auger 12 rotatably connected to the oil trough 11, the oil trough 11 contains rubber particles, and the blade height of the auger 12 is lower than the diameter of the wire and cable, and the height of the auger 12 is 3-5 mm lower than the diameter of the wire and cable.

[0038] Put the rubber particles into the oil tank 11, then start the oil storage tank 5 and pour an appropriate amount of oil into the oil tank 11 through the oil pipe 7. When the auger 12 rotates, it will stir the rubber particles to keep the oil in the rubber particles evenly distributed, and will make the rubber particles gather in the middle and be higher than the highest point of the polyethylene U-shaped liner of the auger 12; when working, the wires and cables enter the oil tank 11 and pass through the rubber particles. The wires will be evenly coated with oil when passing through the rubber particles.

[0039] An extrusion assembly is provided above the guide assembly. When the guide assembly is used to transport wires and cables, the extrusion assembly applies pressure to the center of the cable.

[0040] In this embodiment, since the rubber particles will float due to the force during the stirring process of the auger 12, the floating rubber particles will not come into contact with the wires and cables during the transportation of the wires and cables, affecting the oiling effect. Therefore, an extrusion component is provided above the auger 12 to adjust the gap between the auger 12 and the rubber particles.

[0041] Specifically, the extrusion assembly includes a pressing plate 13, the bottom surface of the pressing plate 13 is fitted with the wires and cables, a lifting plate 34 is connected to one side of the pressing plate 13, a cam 14 is fitted on the bottom surface of the lifting plate 34, an adjusting shaft 15 is fixedly connected inside the cam 14, and the adjusting shaft 15 is rotatably connected to the side wall of the oil groove 11.

[0042] According to the different diameters of wires and cables, the adjusting shaft 15 is rotated. During the rotation of the adjusting shaft 15, the cam 14 is driven to rotate in contact with the bottom surface of the lifting plate 34. Since the pressure plate 13 is elastically connected to the inner wall of the oil tank 2, no matter the size of the gap between the pressure plate 13 and the auger 12, the pressure plate 13 is always pressed against the wires and cables. In this way, the wires and cables can always be in contact with the rubber particles and generate a certain extrusion force, ensuring that the force of the rubber particles on the cable surface is sufficient, thereby ensuring that the cable is fully and evenly oiled during the processing process.

[0043] A cleaning assembly is provided at the outlet of the oil tank 2, and is used for cleaning the surface of wires and cables. The cleaning assembly includes a pipe 16, and one end of the pipe 16 is fixedly connected to the end of the oil trough 11 away from the cable introduction wheel 3. The pipe 16 has a circular array of bristles, and the bristles fit the surface of the wires and cables.

[0044] In this embodiment, after the cable comes out of the oil tank 11 , it enters the pipe 16 , and the brush provided in the pipe 16 is used to remove impurities and oil on the surface of the cable.

[0045] The cleaning assembly also includes four groups of rollers 10, and a bracket 27 is fixedly installed on the outer wall of the oil tank 2. Every two groups of rollers 10 slide symmetrically in the bracket 27. A slider 30 is fixedly installed at the bottom of the roller 10, and a slide groove 33 is provided in the bracket 27 to match the slider 30. The slider 30 is threaded with a first screw 31 and a second screw 32, respectively. One end of one group of first screws 31 is fixedly installed with a motor 26, and an encoder is provided at one end of the adjusting shaft 15. The encoder and the motor 26 are electrically connected. A synchronous pulley 29 is fixedly installed at one end of the first screw 31, and the two groups of synchronous pulleys 29 are connected by a transmission belt 28. The first screw 31 and the second screw 32 are fixedly connected, and the first screw 31 is a left-handed external thread, and the second screw 32 is a right-handed external thread.

[0046] In this embodiment, a cleaning component is provided at the cable outlet of the oil tank 2, including four groups of rollers 10 with adjustable spacing, one of which is connected to a motor 26 at the bottom of one group of rollers 10, and the motor 26 is connected to the encoder at one end of the adjusting shaft 15 by electrical signal. After the adjusting shaft 15 adjusts the position of the pressure plate 13 according to the cable, the encoder identifies the rotation angle of the adjusting shaft 15 and transmits it to the PLC in the electrical cabinet 1. The PLC converts the data and transmits it to the motor 26. The motor 26 drives the synchronous pulley 29 at the shaft end to rotate, and transmits it to the roller 10 on the other side through the transmission belt 28. A slider 30 is provided at the bottom of 10, and the slider 30 slides in a slide groove 33 opened in the bracket 27. Therefore, the synchronous pulley 29 drives the first screw 31 to rotate, thereby causing the slider 30 to slide. At the same time, the first screw 31 and the second screw 32 are fixedly connected, and can also drive the corresponding slider 30 to move. Since the first screw 31 and the second screw 32 are left-handed external threads and right-handed external threads respectively, the synchronous rotation of the first screw 31 and the second screw 32 can adjust the distance between the two adjacent groups of rollers 10, thereby realizing secondary cleaning of the oil on the cable surface.

[0047] Sponge sheets are provided on the surfaces of the first guide wheel 8 , the second guide wheel 20 and the roller shaft 10 .

[0048] It should be noted that sponge sheets are provided on the surfaces of the first guide wheel 8, the second guide wheel 20 and the roller 10. The sponge sheets have strong adsorption force and can clean the oil on the cable surface as quickly as possible.

[0049] A tensioning assembly for conveying and stretching wires and cables is provided between the cleaning assembly and the guide assembly. The tensioning assembly comprises a first guide wheel 8 and a second guide wheel 20 rotatably mounted at the cable outlet of the fuel tank 2. A horizontal plate 35 is fixedly mounted on one side of the top of the fuel tank 2. A lifting rod 17 is slidably connected within the horizontal plate 35. The bottom end of the lifting rod 17 is fixedly connected to a support 19. The first guide wheel 8 is rotatably mounted within the support 19. A spring 18 is provided between the support 19 and the horizontal plate 35. The spring 18 is sleeved on the outside of the lifting rod 17.

[0050] The pipeline 16 is arranged at an inclination, and the connection between the pipeline 16 and the oil trough 11 is at an inclined low position. It should be noted that the pipeline 16 is arranged at an inclination, and its high end faces the second guide wheel 20 .

[0051] Since the cable is not in a fully stretched state during the oiling stage, if the cable cannot be fully stretched and tensioned during the cleaning process after the oil is discharged, the cleaning effect of the cable surface will be affected. Therefore, a first guide wheel 8 is provided between the pipe 16 and the second guide wheel 20. The first guide wheel 8 is connected to the bottom of the cross plate 35 through the support 19 and the lifting rod 17 sliding rod. Since a spring 18 is connected between the cross plate 35 and the support 19, the cable can maintain the stretching and tensioning effect when it is in contact with the bottom of the first guide wheel 8, which can better ensure the oil cleaning effect during cleaning.

[0052] A third guide wheel 21 is provided on one side of the bracket 27, and a fourth guide wheel 22 is provided on the outer wall of the oil tank 2 below the third guide wheel 21. An oil receiving box 9 is provided below the bracket 27, and a winding roller 23 is provided on one side of the oil receiving box 9. An electric slide 24 and a linear guide rail 25 are respectively connected between the winding roller 23 and the oil receiving box 9.

[0053] In this embodiment, when the cable passes through the outlet position of the oil tank 2, it has not yet been cleaned by the roller 10, and there is an inevitable possibility of oil dripping. Therefore, an oil receiving box 9 is provided under the bracket 27 to receive the dripping oil. At the same time, the third guide wheel 21 and the fourth guide wheel 22 are used to continuously tension and transport the cable, and the winding roller 23 is used to wind up the oiled and cleaned cable. It should be noted that an electric slide 24 and a linear guide rail 25 are respectively provided at the bottom of the winding roller 23. According to the conveying speed of the cable, the running speed of the electric slide 24 is set to ensure that the winding roller 23 moves during the winding process, and ensures that the cable will not overlap during the winding process, avoiding the impact of subsequent packaging and warehousing.

[0054] The bottom of the oil receiving box 9 is fixedly connected to a return pipe 6, a pump body 36 is provided in the return pipe 6, one end of the return pipe 6 is connected to the oil storage tank 5, and the flow meter and the pump body 36 are electrically connected.

[0055] The oil receiving box 9 and the oil storage tank 5 are connected by a return pipe 6. At the same time, a pump body 36 is provided in the return pipe 6. When the oil in the oil receiving box 9 reaches a certain volume, the pump body 36 is started to pump the oil in the oil receiving box 9 into the oil storage tank 5 in time to replenish the oil.

[0056] It should be noted that those skilled in the art know that a filtering device is provided in the oil receiving box 9 to filter the dripping oil before reusing it to ensure the quality of the cable oil treatment.

[0057] In the present invention, a PLC control system is provided in the electrical cabinet 1, which controls the oil storage tank 5 to supply oil to the oil tank 2. A flow meter is provided between the oil storage tank 5 and the oil pipe 7 to monitor the oil level in the oil storage tank 5 and supply oil to the oil tank 2 in a timely manner as needed.

[0058] A cable introduction wheel 3 is provided at the entrance of the outer wall of the oil tank 2. The cable enters the oil tank 11 through the cable introduction wheel 3. According to the different diameters of the wires and cables, the adjusting shaft 15 is rotated. During the rotation of the adjusting shaft 15, the cam 14 is driven to rotate in contact with the bottom surface of the lifting plate 34. Since the pressing plate 13 is elastically connected to the inner wall of the oil tank 2, no matter the size of the gap between the pressing plate 13 and the auger 12, the pressing plate 13 is always pressed against the wires and cables. In this way, the wires and cables can always contact with the rubber particles and generate a certain extrusion force, ensuring that the force of the rubber particles on the cable surface is sufficient, thereby ensuring that the cables are fully and evenly oiled during the processing process; at the same time, the wires and cables enter the oil tank 11 and pass through the rubber particles. The wires will be evenly coated with oil when passing through the rubber particles;

[0059] Then, the cable comes out of the oil tank 11 and enters the pipe 16. During the conveying process, the brush provided in the pipe 16 is used to remove impurities and oil on the surface of the cable.

[0060] The motor 26 is connected to the encoder electrical signal at one end of the adjusting shaft 15. After the adjusting shaft 15 adjusts the position of the pressure plate 13 according to the cable, the encoder identifies the rotation angle of the adjusting shaft 15 and transmits it to the PLC in the electrical cabinet 1. The PLC converts the data and transmits it to the motor 26. The motor 26 drives the synchronous pulley 29 at the shaft end to rotate, and transmits it to the synchronous pulley 29 at the shaft end of the roller shaft 10 on the other side through the transmission belt 28. At the same time, it drives the first screw 31 and the second screw 32 to rotate. Since the first screw 31 and the second screw 32 are left-handed and right-handed external threads respectively, the synchronous rotation of the first screw 31 and the second screw 32 can drive the slider 30 to move, thereby adjusting the distance between the two adjacent groups of roller shafts 10, thereby achieving secondary cleaning of the oil on the cable surface.

[0061] An oil receiving box 9 is provided under the bracket 27 to receive the dripping oil. At the same time, the third guide wheel 21 and the fourth guide wheel 22 are used to continuously tension and transmit the cable, and the cable after oiling and cleaning is wound up in cooperation with the winding roller 23. It should be noted that the bottom of the winding roller 23 is respectively provided with an electric slide 24 and a linear guide rail 25. According to the conveying speed of the cable, the running speed of the electric slide 24 is set to ensure that the winding roller 23 moves during the winding process, ensuring that the cable will not be overlapped and wound during the winding process, thereby avoiding the impact of subsequent packaging and storage.

[0062] When the oil in the oil receiving box 9 reaches a certain volume, the pump body 36 is started to pump the oil in the oil receiving box 9 into the oil storage tank 5 in time to replenish the oil.

[0063] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
