Description

Technical Field

[0001] The invention relates to the field of power line production, in particular to a power line insulation layer covering device. Background Art

[0002] During the production process of power cords, in order to ensure their safety and durability, an insulating layer must be wrapped around the outer surface of the conductive core wire (usually made of copper wire). The main function of this insulating layer is to prevent current leakage, thereby avoiding electric shock accidents and extending the service life of the power cord.

[0003] In the prior art, the insulating layer is mostly made of materials such as PVC particles and polyethylene, which are heated and mixed in an extruder to transform them into a fluid state. Subsequently, these insulating materials in a fluid state are introduced into a coating machine, and the core wire passes through the coating machine to form a wire skin insulating layer on its surface. However, in actual applications, when the insulating materials in a fluid state are continuously squeezed into the coating machine, the temperature of the newly added materials is often higher than the temperature of the original materials in the coating machine. This temperature difference leads to inconsistent fluidity of the insulating materials inside the coating machine, which in turn causes uneven thickness of the coating layer on the surface of the core wire, and even defects such as bubbles or cracks. These problems will not only reduce the insulation performance and durability of the power cord, but may also cause electrical failures and increase the risk of safety accidents.

[0016] 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; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” 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.

[0018] The power cord is composed of a core wire and an insulating layer. Usually, an insulating layer is wrapped around the core wire to ensure that it has both conductive properties and improved safety and durability. However, during the wrapping process of the insulating layer, defects such as uneven thickness of the insulating layer, bubbles, and cracks may occur. In order to solve these problems, the present invention proposes a power cord insulating layer wrapping device.

[0019] like Figure 1-Figure 4 As shown, in some embodiments, a power line insulation layer covering device includes a covering component 3 and a fixing component 4. Specifically, the covering component 3 is designed to be installed inside the fixing component 4, and the covering component 3 rotates inside the fixing component 4.

[0020] The coating assembly 3 includes an incoming wire coating mechanism 31, an outgoing wire coating mechanism 32 and a transmission mechanism 33. The incoming wire coating mechanism 31 and the outgoing wire coating mechanism 32 are respectively connected to the transmission mechanism 33, and the function of the transmission mechanism 33 is to coordinately drive the two coating mechanisms to rotate synchronously. Such a design ensures that the insulation layer in the molten state can maintain a stable uniformity during the coating process of the core wire of the power cord 6, avoiding uneven thickness or incomplete coating of the insulation layer on the core wire due to inconsistent temperature, thereby improving the coating quality.

[0021] A mixing chamber is provided between the incoming wire coating mechanism 31 and the outgoing wire coating mechanism 32. The main function of the mixing chamber is to store and mix the insulating materials. A plurality of stirring blades 35 are provided inside the mixing chamber. The stirring blades 35 are evenly distributed along the side wall of the mixing chamber, so that the insulating materials can be fully mixed during the coating process and maintain the consistency of their fluidity, thereby improving the coating effect and the quality of the insulating materials.

[0022] The outlet wire covering mechanism 32 is particularly provided with an insulation layer shaping hole 323 and an outlet wire cover 324. The insulation layer shaping hole 323 passes through the outlet wire cover 324 to ensure that the insulation layer can evenly cover the surface of the core wire. In addition, the continuous rotation of the outlet wire cover 324 ensures that the thickness of the final insulation layer is uniform and prevents the formation of bubbles and cracks, thereby effectively improving the overall quality and safety of the power cord 6.

[0023] It is worth noting that the core wire of the power cord 6 enters the mixing chamber from the inlet wire coating mechanism 31, where the mixing chamber is already filled with flowing insulating material. After starting the transmission mechanism 33, the inlet wire coating mechanism 31 and the outlet wire coating mechanism 32 begin to rotate synchronously, driving multiple stirring blades 35 to rotate around the core wire to ensure that the insulating material in the mixing chamber is fully mixed. After the core wire is coated with an insulating layer in the mixing chamber, a complete power cord 6 is formed. Then, under the action of an external winder, the power cord 6 passes through the insulating layer forming hole 323. During the process of passing through, the power cord 6 will pass through the outlet wire cover 324. In particular, when the outlet wire cover 324 continues to rotate, the insulating layer on the surface of the power cord 6 can be prevented from having uneven thickness due to gravity.

[0024] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, the fixing assembly 4 is provided with a first fixing cover 41, a second fixing cover 42 and a feed hole 43. Specifically, the first fixing cover 41 and the second fixing cover 42 are fixedly connected by bolts, so that a mounting groove is formed between the first fixing cover 41 and the second fixing cover 42, and the mixing bin is arranged inside the mounting groove.

[0025] In addition, the feed hole 43 is arranged on one side of the second fixed cover 42, so that the feed hole 43 and the mixing bin can be smoothly connected. Such a design can ensure that the insulating material can smoothly enter the mixing bin.

[0026] In particular, the first fixed cover 41 is also specially designed with a first connection hole 411 and a first limiting groove 412. The incoming wire covering mechanism 31 is connected to the first fixed cover 41 by passing through the first connection hole 411, and the first limiting groove 412 is closely matched with the incoming wire covering mechanism 31, ensuring the precise position and stability of the incoming wire covering mechanism 31 during operation. This design improves the reliability of the device.

[0027] Similarly, the second fixed cover 42 also includes a second connection hole 421 and a second limiting groove 422. The outlet wire covering mechanism 32 is connected to the second fixed cover 42 by passing through the second connection hole 421, and the second limiting groove 422 is closely matched with the outlet wire covering mechanism 32, ensuring the precise position and stability of the outlet wire covering mechanism 32 during operation.

[0028] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the incoming wire covering mechanism 31 includes an incoming wire covering housing 311, a first transmission wheel 312 and a core wire guide hole 313. Specifically, the incoming wire covering housing 311 is connected to the first fixed cover 41, and the incoming wire covering housing 311 is supported by the first fixed cover 41 so that it can rotate stably and smoothly during use.

[0029] The first transmission wheel 312 is fixed to the outside of the neck of the incoming wire covering shell 311. The first transmission wheel 312 is connected to one end of the transmission mechanism 33, driving the incoming wire covering shell 311 to rotate. Furthermore, a first limit block 314 is specially designed on the outside of the barrel of the incoming wire covering shell 311, which is slidably connected to the first limit groove 412. The limit block is slidably connected to the first limit groove 412, so that the entire incoming wire covering mechanism 31 can maintain a stable position during operation. One end of the stirring blade 35 is fixed to the inner wall of the incoming wire covering shell 311 to ensure that the stirring blade 35 can rotate with it.

[0030] In addition, the core wire guide hole 313 is arranged at the neck of the incoming wire sheathing shell 311, and is connected to the mixing chamber, so as to ensure that the core wire can be smoothly transferred from the incoming wire sheathing shell 311 to the mixing chamber. The core wire guide hole 313 is designed as a tapered hole, which helps to correct the position of the core wire so that it can maintain the correct direction and position before entering the mixing chamber. Through this design, the core wire can be effectively prevented from being twisted or misaligned during the sheathing process, thereby improving the quality and efficiency of the insulation layer sheathing of the power cord 6.

[0031] Similarly, in some embodiments, the outgoing wire covering mechanism 32 has the same structure as the incoming wire covering mechanism 31, and also includes an outgoing wire covering shell 321 and a second transmission wheel 322. Specifically, the outgoing wire covering shell 321 is connected to the second fixed cover 42, and the outgoing wire covering shell 321 is supported by the second fixed cover 42, so that it can rotate stably and smoothly during use.

[0032] The structure and position of the second transmission wheel 322 are the same as those of the first transmission wheel 312, and it is also fixed on the outside of the neck of the outlet wire covering shell 321. The second transmission wheel 322 is connected to the other end of the transmission mechanism 33, driving the outlet wire covering shell 321 to rotate. Furthermore, a second limit block 325 is provided on the outside of the barrel of the outlet wire covering shell 321. The second limit block 325 cooperates with the second limit groove 422 in a sliding connection, so that during the outlet wire covering process, the second limit block 325 can effectively limit the movement range of the outlet wire covering shell 321, thereby ensuring the uniformity and consistency of the insulation layer covering.

[0033] In particular, at one end of the neck of the wire sheathing shell 321, there is a wire cover 324 which is fixedly connected to the wire sheathing shell 321. This connection method not only ensures the tight connection between the wire cover 324 and the wire sheathing shell 321, but also ensures that during the sheathing process, the wire cover 324 can effectively prevent impurities and dust from entering, thereby ensuring the quality of the insulation layer.

[0034] Subsequently, in order to achieve the shaping of the insulating layer, the insulating layer shaping hole 323 is designed to pass through the outlet wire coating shell 321 and communicate with the mixing chamber. This design enables the insulating layer to enter the insulating layer shaping hole 323 through the mixing chamber during the coating process, so that the coating is completed in the mixing chamber, and the excess insulating layer is removed through the insulating layer shaping hole 323. In this way, it can be ensured that the shape and size of the insulating layer meet the predetermined technical requirements, thereby improving the overall quality and performance of the power cord 6.

[0035] Furthermore, in some embodiments, the covering assembly 3 further includes a driving mechanism 34 , which is connected to the transmission mechanism 33 , and the transmission mechanism 33 is driven to rotate by the driving mechanism 34 , thereby driving the rotation of the incoming wire covering mechanism 31 and the outgoing wire covering mechanism 32 .

[0036] Specifically, the transmission mechanism 33 includes a transmission shaft 331 and a plurality of driven wheels 332, which are arranged radially along the transmission shaft 331. The driven wheel 332 at one end is transmission-connected to the incoming wire covering mechanism 31, and the driven wheel 332 at the other end is transmission-connected to the outgoing wire covering mechanism 32.

[0037] In addition, the driving mechanism 34 is provided with a driving motor 342 and a driving wheel 341, the driving wheel 341 is fixedly connected to the output end of the driving motor 342, and the driving wheel 341 is drivingly connected to a driven wheel 332 located in the middle section of the transmission shaft 331. In this way, the driving motor 342 can drive the driving wheel 341, and then drive each driven wheel 332 through the transmission shaft 331, so as to realize the transmission of the incoming wire coating mechanism 31 and the outgoing wire coating mechanism 32, thereby completing the mixing of the insulating materials.

[0038] like Figure 1 , Figure 6 and Figure 7 As shown, the insulation layer coating device also includes an extruder 1 and a supporting assembly 5. An extrusion head 2 is provided between the extruder 1 and the fixing assembly 4. The extrusion head 2 is connected to the feed hole 43 to ensure that the insulation material in the extruder 1 can enter the mixing chamber through the extrusion head 2.

[0039] The fixing assembly 4 is arranged on the upper part of the supporting assembly 5, and plays the role of supporting the fixing assembly 4 and the covering assembly 3, so as to ensure the stability and accuracy of the covering process.

[0040] Further, in some embodiments, the support assembly 5 includes a support vertical plate 51 and a support horizontal plate 52. The support vertical plate 51 is disposed between the fixed assembly 4 and the support horizontal plate 52 to support the entire device. The support vertical plate 51 is axially connected to the transmission shaft 331 to ensure that the transmission shaft 331 can rotate smoothly, thereby stably transmitting power.

[0041] In particular, the support cross plate 52 is provided with an avoidance groove 53, and the function of the avoidance groove 53 is to allow the transmission chain to pass through, and the transmission chain connects the driving wheel 341 and the driven wheel 332, so that the transmission shaft 331 can rotate smoothly. The transmission chain connecting the driving wheel 341 and the driven wheel 332 passes through the avoidance groove 53, ensuring the smooth operation of the transmission chain. The driving motor 342 is fixedly connected to the lower part of the support cross plate 52, and the function of the driving motor 342 is to provide power to drive the transmission shaft 331 and the transmission chain to rotate, thereby realizing the normal operation of the covering component 3.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0043] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
