Description

Technical Field

[0001] The present invention relates to the field of power cord production, and specifically to a device for coating an insulating layer on a power cord. Background Art

[0002] During the production 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, thus avoiding electric shock accidents, and can extend 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. After being heated and mixed by an extruder, it is transformed into a fluid state. Subsequently, these fluid insulating materials 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 fluid insulating materials are continuously extruded into the coating machine, the temperature of the newly added materials is often higher than that of the original materials in the coating machine. This temperature difference causes the fluidity of the insulating materials inside the coating machine to be inconsistent, resulting in uneven thickness of the coating layer on the surface of the core wire, and even defects such as bubbles or cracks. These problems 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. Summary of the Invention

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship 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 orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0036] 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 not only has electrical conductivity but also improves safety and durability. However, during the wrapping process of the insulating layer, defects such as uneven thickness, bubbles, and cracks may occur. To solve these problems, the present invention proposes a power cord insulating layer coating device.

[0037] As Figures 1 - 4As shown, in some embodiments, a power cord insulation layer covering device includes a covering assembly 3 and a fixing assembly 4. Specifically, the covering assembly 3 is designed to be installed inside the fixing assembly 4, and the covering assembly 3 rotates within the fixing assembly 4.

[0038] Among them, the covering assembly 3 includes an inlet covering mechanism 31, an outlet covering mechanism 32, and a transmission mechanism 33. The inlet covering mechanism 31 and the outlet covering mechanism 32 are respectively connected to the transmission mechanism 33. The function of the transmission mechanism 33 is to coordinately drive these two covering mechanisms to rotate synchronously. Such a design ensures that during the covering process of the core wire of the power cord 6, the molten insulation layer can maintain a stable uniformity, avoiding uneven thickness or incomplete covering of the insulation layer on the core wire due to inconsistent temperatures, thereby improving the covering quality.

[0039] Between the inlet covering mechanism 31 and the outlet covering mechanism 32, a mixing chamber is provided. The main function of this mixing chamber is to store and mix the insulation material. The interior of the mixing chamber is equipped with a plurality of stirring blades 35, which are evenly distributed along the side wall of the mixing chamber, enabling the insulation material to be fully mixed during the covering process, maintaining the consistency of its fluidity, and thus improving the covering effect and the quality of the insulation material.

[0040] The outlet covering mechanism 32 is particularly provided with an insulation layer shaping hole 323 and an outlet cover 324. The insulation layer shaping hole 323 penetrates the outlet cover 324, aiming to ensure that the insulation layer can evenly cover the surface of the core wire. In addition, the continuous rotation of the outlet cover 324 ensures the uniform thickness of the final insulation layer and prevents the formation of bubbles and cracks, thereby effectively improving the overall quality and safety of the power cord 6.

[0041] It should be noted that the core wire of the power cord 6 enters the mixing chamber from the inlet covering mechanism 31, where the mixing chamber is already filled with flowing insulation material. After starting the transmission mechanism 33, the inlet covering mechanism 31 and the outlet covering mechanism 32 start to rotate synchronously, driving a plurality of stirring blades 35 to rotate around the core wire to ensure that the insulation material in the mixing chamber is fully mixed. After the core wire is covered with the insulation layer in the mixing chamber, a complete power cord 6 is formed. Then, under the action of an external winding machine, the power cord 6 passes through the insulation layer shaping hole 323. During the passing process, the power cord 6 will pass through the outlet cover 324. In particular, when the outlet cover 324 rotates continuously, it can prevent the problem of uneven thickness of the insulation layer on the surface of the power cord 6 due to the action of gravity.

[0042] Such as Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown, in some embodiments, the fixing component 4 is provided with a first fixing cover 41, a second fixing cover 42, and a feeding hole 43. Specifically, the first fixing cover 41 and the second fixing cover 42 are fixedly connected by bolts, forming an installation groove between the first fixing cover 41 and the second fixing cover 42, and the mixing bin is arranged inside the installation groove.

[0043] In addition, the feeding hole 43 is arranged on one side of the second fixing cover 42, enabling smooth communication between the feeding hole 43 and the mixing bin. Such a design ensures the smooth entry of the insulating material into the mixing bin.

[0044] Particularly, the first fixing 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 fixing cover 41 by passing through the first connection hole 411, and the first limiting groove 412 closely cooperates 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.

[0045] Similarly, the second fixing cover 42 also includes a second connection hole 421 and a second limiting groove 422. The outgoing wire covering mechanism 32 is connected to the second fixing cover 42 by passing through the second connection hole 421, and the second limiting groove 422 closely cooperates with the outgoing wire covering mechanism 32, ensuring the precise position and stability of the outgoing wire covering mechanism 32 during operation.

[0046] As Figure 3 、 Figure 4 and Figure 5 shown, in some embodiments, the incoming wire covering mechanism 31 includes an incoming wire covering housing 311, a first driving wheel 312, and a core wire guiding hole 313. Specifically, the incoming wire covering housing 311 is connected to the first fixing cover 41, and the first fixing cover 41 supports the incoming wire covering housing 311, enabling it to rotate stably and smoothly during use.

[0047] The first driving wheel 312 is fixed to the outer side of the neck of the incoming wire covering housing 311. The first driving wheel 312 is connected to one end of the driving mechanism 33, driving the incoming wire covering housing 311 to rotate. Further, a first limiting block 314 is specially designed on the outer side of the barrel part of the incoming wire covering housing 311, which is slidably connected to the first limiting groove 412. The sliding connection between the limiting block and the first limiting groove 412 ensures the stability of the position of the entire incoming wire covering mechanism 31 during operation. One end of the stirring blade 35 is fixed to the inner wall of the incoming wire covering housing 311, ensuring that the stirring blade 35 can rotate along with it.

[0048] In addition, the core wire guiding hole 313 is provided at the neck of the incoming wire covering housing 311 and communicates with the mixing chamber to ensure that the core wire can be smoothly transmitted from the incoming wire covering housing 311 to the mixing chamber. The core wire guiding hole 313 is designed as a tapered hole, and this design 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 situation of the core wire being twisted or misaligned during the covering process can be effectively avoided, thereby improving the quality and efficiency of the insulation layer covering of the power cord 6.

[0049] Similarly, in some embodiments, the structure of the outgoing wire covering mechanism 32 is the same as that of the incoming wire covering mechanism 31, and it also includes an outgoing wire covering housing 321 and a second driving wheel 322. Specifically, the outgoing wire covering housing 321 is connected to the second fixed cover 42, and the second fixed cover 42 supports the outgoing wire covering housing 321 so that it can rotate stably and smoothly during use.

[0050] The structure and position of the second driving wheel 322 are the same as those of the first driving wheel 312. It is also fixed on the outer side of the neck of the outgoing wire covering housing 321. The second driving wheel 322 is drivingly connected to the other end of the transmission mechanism 33 to drive the outgoing wire covering housing 321 to rotate. Further, a second limiting block 325 is provided on the outer side of the cylindrical part of the outgoing wire covering housing 321. The second limiting block 325 cooperates with the second limiting groove 422 in a sliding connection manner, so that during the outgoing wire covering process, the second limiting block 325 can effectively limit the moving range of the outgoing wire covering housing 321, thereby ensuring the uniformity and consistency of the insulation layer covering.

[0051] Particularly, at one end of the neck of the outgoing wire covering housing 321, an outgoing wire cover 324 is provided, which is fixedly connected to the outgoing wire covering housing 321. This connection method not only ensures the tight combination between the outgoing wire cover 324 and the outgoing wire covering housing 321, but also ensures that the outgoing wire cover 324 can effectively prevent impurities and dust from entering during the covering process, thereby ensuring the quality of the insulation layer.

[0052] Subsequently, in order to shape the insulation layer, the insulation layer shaping hole 323 is designed to pass through the outgoing wire covering housing 321 and communicate with the mixing chamber. This design enables the insulation layer to enter the insulation layer shaping hole 323 through the mixing chamber during the covering process, so that the covering is completed in the mixing chamber, and the excess insulation layer is removed through the insulation layer shaping hole 323. In this way, it can be ensured that the shape and size of the insulation layer meet the predetermined technical requirements, thereby improving the overall quality and performance of the power cord 6.

[0053] Further, in some embodiments, the covering assembly 3 further includes a driving mechanism 34. The driving mechanism 34 is connected to the transmission mechanism 33. By driving the driving mechanism 34, the transmission mechanism 33 is rotated, and further, the rotation of the incoming wire covering mechanism 31 and the outgoing wire covering mechanism 32 is driven.

[0054] Specifically, the transmission mechanism 33 includes a transmission shaft 331 and a plurality of driven wheels 332. These driven wheels 332 are arranged radially along the transmission shaft 331. Among them, the driven wheel 332 at one end is in transmission connection with the incoming wire covering mechanism 31, while the driven wheel 332 at the other end is in transmission connection with the outgoing wire covering mechanism 32.

[0055] 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. The driving wheel 341 is in transmission connection with the driven wheel 332 in the middle section of the transmission shaft 331. In this way, the driving motor 342 can drive the driving wheel 341, and further drive each driven wheel 332 through the transmission shaft 331, so as to realize the transmission of the incoming wire covering mechanism 31 and the outgoing wire covering mechanism 32, and thus complete the mixing work of the insulating material.

[0056] As Figure 1 、 Figure 6 and Figure 7 shown, the insulating layer covering device further includes an extruder 1 and a support assembly 5. An extrusion head 2 is provided between the extruder 1 and the fixing assembly 4. The extrusion head 2 is communicated with the feed hole 43 to ensure that the insulating material in the extruder 1 can enter the mixing bin through the extrusion head 2.

[0057] The fixing assembly 4 is arranged on the upper part of the support assembly 5, which plays a role in supporting the fixing assembly 4 and the covering assembly 3, and ensures the stability and accuracy of the covering process.

[0058] 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 arranged between the fixing assembly 4 and the support horizontal plate 52, which plays a role in supporting the whole device. The support vertical plate 51 is axially connected to the transmission shaft 331 to ensure that the transmission shaft 331 can rotate smoothly, so as to stably transmit power.

[0059] Particularly, the support horizontal plate 52 is provided with an avoidance groove 53. The function of the avoidance groove 53 is to allow the transmission chain to pass through. The transmission chain connects the driving wheel 341 and the driven wheels 332, so that the transmission shaft 331 can rotate smoothly. The transmission chain connecting the driving wheel 341 and the driven wheels 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 horizontal plate 52. The function of the driving motor 342 is to provide power to drive the transmission shaft 331 and the transmission chain to rotate, so as to realize the normal operation of the covering assembly 3.
