Description

Technical Field

[0001] This utility model relates to the technical field of wire and cable production equipment, specifically to an oiling device for wire and cable production. Background Technology

[0002] The core function of the oiling device in wire and cable production is to coat the surface of the conductor with a thin and uniform special lubricating oil film before the conductor enters the extruder. The oil film plays a role in lubrication and friction reduction, which can significantly reduce the friction between the conductor and the high-temperature molten plastic during the extrusion process, thereby effectively preventing the conductor from being stretched, scratched or broken.

[0003] The patent application with Chinese application number 202011343287.X discloses a device for oiling the core wire in the production of wires and cables, including a base plate, a vertical plate and a support plate. The vertical plate is fixedly connected to the left end of the base plate, and a horizontal plate is fixedly welded to the upper end of the vertical plate. The support plate is fixedly connected to the base plate, and a guide plate is fixedly connected to the upper end of the support plate. The vertical plate has a wire inlet. A main belt roller with front and rear symmetrical connection is rotatably connected to the right side of the vertical plate, and a secondary belt roller is arranged below the main belt roller.

[0004] Existing oiling devices may cause excessive oil to adhere to the cable surface. Excessive oil may vaporize at high temperatures, forming bubbles, which can lead to "pinholes" or "bubbles" in the insulation layer, severely damaging the insulation performance, causing high-voltage test breakdown, and resulting in poor cable quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an oiling device for wire and cable production, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oiling device for wire and cable production, comprising an oiling box, a first support frame fixedly connected to the top of the oiling box, a first guide wheel movably connected to the top of the first support frame, a second guide wheel movably connected inside the oiling box to the right side of the first support frame, a second support frame fixedly connected to the top of the oiling box to the right side of the second guide wheel, and a third guide wheel movably connected to the top of the second support frame.

[0007] Preferably, a scraping cylinder is fixedly connected inside the first support frame, and a scraper is fixedly connected inside the scraping cylinder, with a small gap between the scraper and the surface of the first support frame.

[0008] Preferably, a fan motor is fixedly connected inside the scraper cylinder.

[0009] Preferably, a drive motor is fixedly connected to the top of the oil box at the top of the second guide wheel, a baffle is fixedly connected to the outer wall of the drive motor, a rotating frame is provided inside the baffle, the rotating frame is fixedly connected to the output shaft of the drive motor, a push wheel is movably connected inside the rotating frame, and an impact plate is provided on the left side of the push wheel.

[0010] This utility model provides an oiling device for wire and cable production. It has the following beneficial effects:

[0011] 1. The oiling device used in the production of wires and cables pulls the cable from the bottom of the second guide wheel to the first guide wheel, causing the cable to move upward. This allows excess oil adhering to the cable surface to flow naturally downward under the action of gravity and back into the oiling box, which can reduce the amount of oil adhering to the cable surface, improve the forming quality of the cable, and facilitate the re-adhesion of oil to the cable surface.

[0012] 2. The oiling device used in the production of this wire and cable uses a scraper to scrape off the oil adhering to the surface of the cable and collect it on the scraper surface. This reduces the oil adhering to the surface of the first guide wheel and increases the amount of oil that is separated when the first guide wheel comes into contact with the cable. This can reduce the amount of oil adhering to the cable and thus improve the forming quality of the cable.

[0013] 3. The oiling device used in the production of this wire and cable uses a push wheel to push the cable to impact the impact plate, causing the cable to shake and shake off the oil adhering to the surface. This reduces the amount of oil on the cable surface and improves the forming quality of the cable. At the same time, the vibration of the scraper drum reduces the adhesion of oil inside the scraper drum and promotes the return of oil inside the scraper drum to the oiling box, thereby improving the utilization rate of oil in the cable oiling process.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an oiling device for wire and cable production, including an oiling box 1, a first support frame 2 fixedly connected to the top of the oiling box 1, a first guide wheel 3 movably connected to the top of the first support frame 2, a second guide wheel 4 movably connected inside the oiling box 1 to the right side of the first support frame 2, a second support frame 14 fixedly connected to the top of the oiling box 1 to the right side of the second guide wheel 4, and a third guide wheel 5 movably connected to the top of the second support frame 14.

[0022] The first support frame 2 has a scraper cylinder 6 fixedly connected inside, and the scraper 8 is fixedly connected inside the scraper cylinder 6. The scraper 8 has a small gap with the surface of the first support frame 2.

[0023] The scraper cylinder 6 is internally connected to a fan-blade motor 7.

[0024] A drive motor 10 is fixedly connected to the top of the oil passage box 1 at the top of the second guide wheel 4. A baffle 9 is fixedly connected to the outer wall of the drive motor 10. A rotating frame 11 is provided inside the baffle 9. The rotating frame 11 is fixedly connected to the output shaft of the drive motor 10. A push wheel 12 is movably connected inside the rotating frame 11. An impact plate 13 is provided on the top of the oil passage box 1 at the left side of the push wheel 12. The impact plate 13 is fixedly connected to the scraping cylinder 6.

[0025] Working principle: The cable is passed sequentially through the third guide wheel 5, the second guide wheel 4, and the first guide wheel 3, with the cable contacting the third guide wheel 5 and the first guide wheel 3 at the top and the cable contacting the second guide wheel 4 at the bottom. An appropriate amount of oil is injected into the oil-passing box 1, and the cable is pulled towards the side where the first guide wheel 3 is located. Under the pull of the first guide wheel 3, the second guide wheel 4, and the third guide wheel 5, the cable passes through the oil, completing the oil-passing process. When the cable is pulled from the bottom of the second guide wheel 4 towards the first guide wheel 3, the cable will be in an upward state. Excess oil adhering to the cable surface will naturally flow down under the action of gravity and flow back into the oil-passing box 1, which can reduce the excessive oil adhering to the cable surface. At the same time, the backflow of oil makes it easier for the oil to re-adhere to the cable surface.

[0026] The first guide wheel 3 will come into contact with the cable, causing oil from the cable surface to adhere to the first guide wheel 3. Scraping off the oil adhering to the surface of the first guide wheel 3 increases the amount of oil collected by the first guide wheel 3 when in contact with the cable, thereby reducing the amount of oil adhering to the cable surface. When the first guide wheel 3 rotates, the scraper 8 scrapes off the oil adhering to the surface of the cable and collects it on the surface of the scraper 8. At the same time, the fan motor 7 works to generate a weak airflow, which flows over the surface of the scraper 8, promoting the oil collected on the surface of the scraper 8 to fall back into the oil collection box 1. This reduces the amount of oil adhering to the cable and facilitates the recovery of excess oil.

[0027] During the process of the cable being pulled through the oil, the drive motor 10 drives the rotating frame 11 to rotate, which in turn drives the push wheel 12 to rotate. This causes the push wheel 12 to push the cable, causing it to hit the impact plate 13. The sudden push of the cable creates a shaking motion, which shakes off the oil adhering to the surface of the cable. At the same time, when the cable hits the impact plate 13, the oil on its surface also adheres to the surface of the impact plate 13. As the push wheel 12 continues to push, the impact plate 13 continues to hit, which promotes the return of the oil adhering to the surface of the impact plate 13 to the inside of the oil box 1. Meanwhile, the baffle 9 prevents oil from splashing everywhere when the push wheel 12 rotates.

[0028] In addition, the impact plate 13 is fixedly connected to the scraper cylinder 6. When the impact plate 13 is impacted, the scraper cylinder 6 is pushed and shaken, which reduces the adhesion of oil inside the scraper cylinder 6. The airflow generated by the fan motor 7 can better push the oil inside the scraper cylinder 6 downward, promoting the return of the oil inside the scraper cylinder 6 to the oil box 1.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
