Description

Technical Field

[0001] The present invention relates to the technical field of wire and cable production, and in particular to a covering molding device based on cable production. Background Art

[0002] The overmolding device for cable production is a special equipment used to coat the conductor (such as copper wire, aluminum wire) or cable core with an insulation layer, a sheath layer or other functional layer. Its core function is to evenly and tightly adhere the coating material to the surface of the conductor by physical or chemical methods to meet the electrical performance, mechanical performance and environmental protection requirements of the cable. During use, since the traditional cable core needs to be cooled by cooling water when it is coated on the outside, the cooling water itself will rise in temperature after long-term use, and the circulation speed is low, which will slow down the temperature reduction rate of the cable core after coating, affecting the efficiency of subsequent cable core processing.

[0003] In order to overcome the above-mentioned defects, prior art one (a Chinese patent with announcement number CN220340980U and announcement date 2024-01-12) is a wire and cable core wire covering device, which relates to the field of wire and cable technology, including an equipment component, the equipment component including a support table, a cleaning component and a storage box are provided on the top of the support table, and an insulation component and a heating pipe are provided on the inner wall of the storage box. By guiding the molten cable and wire skin into the feed barrel, it is convenient to cover the wire and cable core wire, and the wire and cable are fully cooled and formed by cold air and cold respectively, so as to achieve a rapid forming effect. The exhaust gas can be introduced into the filter box in the water storage tank through the exhaust pipe, so as to facilitate the dust reduction and temperature reduction treatment of the exhaust gas when it comes into contact with water. After working for a long time, the inner walls of the feed barrel and the discharge barrel are prone to adhere to excess materials that are difficult to clean. After disassembling them, they are cleaned by the cleaning component. At the same time, the insulation component in the storage box prevents its heat from being lost during the cleaning process. The device effectively improves the efficiency; prior art two (publication number (CN112712941A, Chinese patent publication date: 2021-04-27) A wire and cable core wire coating device, comprising a coating cylinder and a material bin: the interior of the coating cylinder is provided with a coating channel with a conical structure, the outlet end of the material bin is provided with a material pipe connected to the inlet end of the coating channel, the inner wall of the coating cylinder and located on the outside of the core wire are provided with a pair of cleaning components for cleaning the core wire, and the cleaning components are circulated with liquid by a cleaning liquid circulation component, the inner wall of the coating cylinder and located on the outside of the core wire are provided with a pair of drying components for drying the core wire, and the drying components are circulated with heat by the coating cylinder. The coating device can perform cyclic cleaning and drying treatment on the outer wall of the cable core wire to be coated by the provided cleaning component and drying component, while removing the residual stains on the outer wall of the cable core wire, it also improves the dryness of the cable core wire, making it convenient for the subsequent coating material to be accurately and stably coated on the surface of the cable core wire, effectively improving the coating effect of the cable core wire.

[0004] The above-mentioned mechanism cools the cable core and then heats it through a heating device to dry the surface to facilitate subsequent processing. However, in actual use, the coating material on the outside of the cable core is mainly melted and then coated on the outside of the cable core. Using heat to dry the coating material again may cause the coating material to soften, which in turn causes gaps in the package, affecting the stability and efficiency of the coating.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The cooling water with rising temperature is transported to the inside of the circulation box through the pipe at the bottom of the cold water tank for filtering and circulation. The filtered cooling water in the circulation box is circulated to the inside of the cold water tank through the water pump to complete the circulation of the cooling water. When the cooling water is circulated, the output end of the drive motor rotates and drives the rotating rod to rotate. When the rotating rod rotates, it drives the fan blades to rotate.

[0018] Furthermore, the movement of the cleaning brush can be used to clean the surface of the filter plate, thereby quickly cleaning the impurities remaining on the surface of the filter plate, avoiding the accumulation of impurities on the surface of the filter plate and affecting the subsequent work efficiency during cooling water filtration.

[0019] 2. The extrusion plate is pushed upward by the cam, so that the elastic airbag on the top of the extrusion plate is squeezed, and the gas inside the elastic airbag is squeezed out. The gas inside the elastic airbag is transported to the nozzle through the hose. The nozzle can be used to blow air to the outside of the cable core, so that the residual water stains on the outside of the cable core are dried, reducing the residual water stains on the outside of the cable core, and facilitating better air-drying of the cable core.

[0020] Furthermore, the cable core in the middle position inside the cold water tank will be pressed downward and immersed in the cooling water to achieve stable cooling treatment. The front and rear ends of the tensioning roller are connected to the pull rod, and the pull rod is slidably connected to the inside of the telescopic rod, so that the height of the tensioning roller can be controlled according to the elastic force of the connecting spring, so that the coated cable core can be stably tensioned and adjusted during transportation. While ensuring that the coated cable core is immersed in the cooling water, it can also avoid the situation where the cable core breaks due to excessive pressing force.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Figure 1-Figure 3 、 Figure 5-Figure 7 and Figure 9The technical solution shown is to solve the problem that the traditional cable core needs to be cooled by cooling water when it is coated on the outside. After long-term use, the cooling water itself temperature rises, and the circulation speed is low, which leads to a slow temperature reduction speed after the cable core is coated, affecting the subsequent cable core processing efficiency: the coating molding device based on cable production discloses a circulation filtering mechanism, including a fixed frame 1, a feeding drum 2 is provided at the upper end of the fixed frame 1, and a spiral feeding rod 4 is connected to the inner rotation of the feeding drum 2, a feeding port 3 is provided on the right side of the top of the feeding drum 2, and a coating group is provided below the feeding drum 2. The cable core body 7 is provided inside the covering component, and a cold water tank 8 is provided on the side of the fixing frame 1; a circulation box 14 is provided at the bottom end of the cold water tank 8, and a circulation filtering mechanism for filtering the cooling water is provided inside the circulation box 14; the covering component includes a melting box 5, and the melting box 5 is fixedly connected to the front end of the fixing frame 1, the melting box 5 is provided below the feeding cylinder 2, and a feeding box 6 is provided inside the melting box 5, and the cable core body 7 passes through the feeding box 6 and extends to the other side of the melting box 5, and one side of the cable core body 7 passes through the melting box 5 and extends to the other side of the cold water tank 8; the circulation filtering mechanism includes The drive motor 17 is provided at the upper end of the side of the circulation box 14. The output end of the drive motor 17 extends to the interior of the circulation box 14 and is installed with a rotating rod 15, and a fan blade 16 is installed on the outside of the rotating rod 15. A filter plate 23 is provided at the lower end of the interior of the circulation box 14; the output end of the drive motor 17 is installed with a threaded rod 18 through a synchronous pulley transmission mechanism, and the outer side of the threaded rod 18 is threadedly connected to a movable block 19, and a positioning box 20 is installed at the bottom end of the movable block 19, and a cleaning brush 22 is installed inside the positioning box 20 through a return spring 21. The bottom end of the cleaning brush 22 is in contact with the filter plate 23. 3; the filter plate 23 itself is tilted and arranged inside the circulation box 14, and the width of the cleaning brush 22 is equal to the width of the filter plate 23; a guide rod 24 is provided at the front end of the circulation box 14, and a slider 25 matching the guide rod 24 is provided on the side of the movable block 19, and a sliding connection is formed between the movable block 19 and the guide rod 24 through the slider 25; the top end of the return spring 21 is connected to the top end of the positioning box 20, and the bottom end of the return spring 21 is connected to the top end of the cleaning brush 22, and an elastic structure is formed between the positioning box 20 and the cleaning brush 22 through the elastic force of the return spring 21.

[0033] In this example, if Figure 2 As shown, first the material enters from the feed port 3, and at the same time the cable core body 7 is synchronously conveyed into the feed box 6. The molten material is uniformly conveyed inside the feed barrel 2 by the spiral feeding rod 4, and the molten material enters the interior of the melting box 5 through the connecting pipe. The molten coating layer is wrapped around the outside of the cable core body 7 to achieve the coating treatment of the cable core; Figure 2As shown, after the cable core is coated, the coated cable core is cooled by a cold water tank 8. After cooling, the coated cable core is reeled and transported, completing the processing of the cable core and its coating structure; Figure 2 and Figure 5 As shown, after the cable core is cooled, the cooling water with increased temperature is transported to the inside of the circulation box 14 through the pipe at the bottom of the cold water tank 8 for filtering and circulation. The filtered cooling water in the circulation box 14 is circulated to the inside of the cold water tank 8 by the water pump to complete the circulation of the cooling water. When the cooling water is circulated, the output end of the driving motor 17 rotates and drives the rotating rod 15 to rotate. When the rotating rod 15 rotates, it drives the fan blades 16 to rotate. When the fan blades 16 rotate, the contact area between the cooling water and the air is increased, thereby making the cooling water circulation process more convenient. The cooling water cooling speed is increased, which is convenient for the subsequent recycling of the cooling water. After the cooling water enters the interior of the circulation box 14, the cooling water will also be filtered through the filter plate 23. The filter plate 23 can filter out impurities generated when the cooling water circulates, reducing the blockage of the cooling water circulation pipe by impurities; and a collection box 26 is provided at the bottom end of the circulation box 14. The bottom end of the collection box 26 is inclined, so that some of the fine impurities that pass through the filter plate 23 will be deposited at the bottom end of the collection box 26. The collection box 26 can be pulled out to achieve the treatment of the fine residual impurities. Figure 5 As shown, the output end of the drive motor 17 can drive the threaded rod 18 to rotate while driving the rotating rod 15 to rotate through the synchronous pulley, wherein the synchronous pulley adopts the gear component and the steel wire synchronous belt commonly used on the market, and the two complete the synchronous drive rotation through the meshing action, so that the threaded rod 18 can realize synchronous rotation and drive its supporting mechanism to operate, and the threaded rod 18 is threadedly connected to the movable block 19. When the movable block 19 moves, it will synchronously drive the positioning box 20 to move, and when the positioning box 20 moves, the cleaning brush 22 inside the positioning box 20 will be driven and move on the surface of the filter plate 23. The movement of the cleaning brush 22 can clean the surface of the filter plate 23, thereby quickly cleaning the impurities remaining on the surface of the filter plate 23, avoiding the accumulation of impurities on the surface of the filter plate 23, affecting the subsequent working efficiency during the cooling water filtration; as shown Figure 9 As shown, a return spring 21 is provided inside the positioning box 20. The return spring 21 can provide the cleaning brush 22 with a certain elastic space, so that the bottom end of the cleaning brush 22 can always fit with the surface of the filter plate 23, so that the surface of the filter plate 23 can be cleaned more thoroughly. At the same time, the filter plate 23 itself has a certain inclination angle, so that the impurities remaining on the surface of the filter plate 23 will automatically flow to the side along with the water flow, reducing the accumulation of impurities.

[0034] Example 2: Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 8 The technical solution shown is to solve the problem that during the cable core coating process, the coating layer on the outside of the cable core needs to be cooled by cooling water. After cooling, water stains will remain on the outer layer of the cable core, and the residual water stains may affect the spark detection of the cable core: the cable production-based coating molding device discloses a drying mechanism, and the upper end of the side of the circulation box 14 is provided with a drying mechanism for reducing water stains on the surface of the cable core; the drying mechanism includes a cam 30, and the cam 30 is fixedly connected to the output end of the drive motor 17, and the upper end of the circulation box 14 is provided with a limiting frame 27, and the interior of the limiting frame 27 is provided with an elastic airbag 28, the bottom end of the elastic airbag 28 is installed with an extrusion plate 29, and the front and rear ends of the elastic airbag 28 are connected to a nozzle 31 through a hose.

[0035] In this example, if Figure 8 As shown, when the output end of the driving motor 17 rotates, it can drive the two cams 30 to rotate. When the cam 30 rotates, the cam 30 pushes the extrusion plate 29 upward, thereby squeezing the elastic airbag 28 at the top of the extrusion plate 29, and the gas inside the elastic airbag 28 is squeezed out. The gas inside the elastic airbag 28 is transported to the nozzle 31 through the hose, and the nozzle 31 can be used to blow air to the outside of the cable core, so that the residual water stains on the outside of the cable core are dried, reducing the residual water stains on the outside of the cable core, facilitating better air-drying of the cable core, facilitating stable spark detection of the cable core after air-drying, and reducing the possibility of being affected during spark detection; as shown Figure 8 As shown, the extrusion plate 29 is slidably connected to the inner side of the limit frame 27. Therefore, after the extrusion plate 29 is pushed upward by the cam 30, the extrusion plate 29 is automatically lowered by its own weight after the cam 30 returns to its initial position. The extrusion plate 29 assists the elastic airbag 28 in resetting its own shape, which is convenient for the subsequent reciprocating blowing treatment on the outside of the cable core. The jet position of the nozzle 31 is facing the output direction of the cable core, so as to facilitate better air drying.

[0036] Example 3: Figure 1 、 Figure 3 、 Figure 4 and Figure 6The technical solution shown is to solve the problem that part of the cable core may not be able to be completely immersed in the cooling water when the cable core is cooled: the cable production-based overmolding device discloses a tensioning adjustment mechanism, and the interior of the cold water tank 8 is provided with a tensioning adjustment mechanism for ensuring the cooling efficiency of the cable core; the tensioning adjustment mechanism includes a fixed roller 9, which is rotatably connected to the interior of the cold water tank 8, and a telescopic rod 13 is installed at the front and rear ends of the cold water tank 8, and the interior of the telescopic rod 13 is slidably connected to a pull-out rod 12, and a tensioning roller 10 is installed at the top of the pull-out rod 12, and the tensioning roller 10 is provided at the middle position inside the cold water tank 8, and a connecting spring 11 is wound around the outside of the pull-out rod 12.

[0037] In this example, if Figure 6 As shown, during the transportation of the cable core after being coated, the cable core can pass through the fixed roller 9 and the tensioning roller 10, and the height of the tensioning roller 10 is controlled by the tensioning adjustment mechanism, so that the cable core is in the middle position inside the cold water tank 8 and will be pressed downward and immersed in the cooling water to achieve stable cooling treatment. The front and rear ends of the tensioning roller 10 are connected to the pulling rod 12, and the pulling rod 12 is slidably connected to the inside of the telescopic rod 13, so that the height of the tensioning roller 10 can be controlled according to the elastic force of the connecting spring 11, so that the coated cable core can be stably tensioned and adjusted during transportation. While ensuring that the coated cable core is immersed in the cooling water, it can also avoid the situation where the cable core is broken due to excessive pressing force. The fixed roller 9 is arranged on the left and right sides of the cold water tank 8, and cooperates with the tensioning roller 10 to press the cable core into the water.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
