[0046] As Figures 1 to 6 shown, the present utility model provides a cable coating device 100. This cable coating device 100 can be used to coat various coatings on the surface of a cable 200, such as talcum powder and gypsum powder, etc. For the convenience of description, this embodiment takes coating a talcum powder coating as an example for illustration. The cable coating device 100 includes a container unit 20, a stirring unit 50, a guiding unit 30, a metering unit 40, and a drying and processing unit 60. The container unit 20 is provided with an accommodating space, and the accommodating space accommodates a suspension 70. The suspension 70 is composed of talcum powder and water. The stirring unit 50 is used to stir the suspension 70 to prevent the talcum powder from precipitating at the bottom of the container unit 20 and maintain the particle uniformity of the talcum powder in the suspension 70. The guiding unit 30 is used to guide the cable 200 to be immersed through the suspension 70 so that the surface of the cable 200 adheres to the suspension 70. The metering unit 40 includes a blower 41. The blower 41 is arranged downstream of the guiding unit 30. The blower 41 is used to blow air at the cable 200 to form an air flow to control the adhesion amount and uniformity of the suspension 70 on the surface of the cable 200. The drying and processing unit 60 is located downstream of the blower 41. The drying and processing unit 60 is used to dry the suspension 70 adhered to the surface of the cable 200 to form a coating layer.

[0047] The cable coating device 100 provided by the present utility model provides an accommodating space by setting the container unit 20, and the accommodating space is internally provided with the suspension 70. The guiding unit 30 guides the cable 200 to be immersed through the suspension 70 so that the surface of the cable 200 adheres to the suspension 70. By setting the blower 41 downstream of the guiding unit 30, the blower 41 blows air to control the adhesion amount and uniformity of the suspension 70, avoid excessive residue of the suspension 70, improve the coating uniformity and control the thickness of the coating layer. Then, by setting the drying and processing unit 60 downstream of the blower 41 to perform a drying process on the surface of the cable 200, the powder adheres to the surface of the cable 200 to form a uniform and thin coating layer.

[0048] Furthermore, the container unit 20 includes a main body 21 and a detachable cover plate 22. A receiving space is provided inside the main body 21, and the cover plate 22 can selectively close the top opening of the receiving space. By providing the cover plate 22 to selectively close the top opening of the receiving space, it is convenient to open the cover plate 22 to fill the suspension 70 into the receiving space, and it is convenient to install the guiding unit 30 and the agitating unit 50. During the coating process, closing the cover plate 22 effectively prevents the suspension 70 from splashing from the top.

[0049] In this embodiment, the main body 21 is made by enclosing with plate-shaped materials. Two threading openings for the cable 200 to pass through are oppositely provided on the main body 21. The cable 200 passes through the threading openings. One side of the cover plate 22 is rotatably connected to the main body 21, and the other side of the cover plate 22 overlaps on the main body 21. A handle is provided on the cover plate 22 for easy opening or closing. In other embodiments, the cover plate 22 can also be snap-connected to the main body 21.

[0050] Furthermore, the container unit 20 further includes a partition 23. The partition 23 is connected to the main body 21. The partition 23 divides the receiving space into a coating space and a metering space. The suspension 70 is collected at the bottom of the coating space. The guiding unit 30 is at least partially disposed in the coating space, and the blower 41 is disposed in the metering space. By providing the partition 23, the guiding unit 30 and the blower 41 are respectively placed in independent spaces. The cable 200 is coated in the coating space, and the adhesion amount and uniformity of the suspension 70 are controlled in the metering space. The two can be carried out simultaneously in independent spaces to avoid mutual interference.

[0051] In this embodiment, two cover plates 22 are arranged side by side. One cover plate 22 is located at the top of the coating space, and the other cover plate 22 is located at the top of the metering space. The two cover plates 22 jointly close the top opening of the receiving space. In other embodiments, one or more cover plates 22 can also be provided. In this embodiment, the blower 41 is disposed inside the main body 21. In other embodiments, the blower 41 can also be separately disposed outside the main body 21.

[0052] For the convenience of coating, the coating space has a bottom surface and two opposite inclined side surfaces. The bottom surface is located between the two inclined side surfaces. Each inclined side surface extends upward in a direction away from the other inclined side surface to converge the suspension 70. By providing the inclined side surfaces, the suspension 70 is converged towards the bottom surface of the coating space, making it easier for the suspension 70 to reach a certain depth, which provides convenience for coating.

[0053] In this embodiment, the side surface of the partition plate 23 is detachably connected to the main body 21, and there is a gap between the bottom of the partition plate 23 and the main body 21, so that the bottoms of the coating space and the metering space are communicated. Part of the suspension 70 dripping into the metering space can flow back into the coating space along the bottom of the metering space and continue to be used for coating, realizing the efficient utilization of the suspension 70. An installation hole is provided in the upper part of the partition plate 23, and the cable 200 passes through the installation hole and is located in both the coating space and the metering space. In other embodiments, the bottom of the metering space may also be set not to be communicated, and the suspension 70 dripping into the metering space is collected and reused by other means.

The preset immersion depth is greater than the diameter of the cable 200. By setting the main wheel disc 32, the cable 200 is wound around the lower edge of the main wheel disc 32 so that the cable 200 is immersed in the suspension 70. As the cable 200 is conveyed, the main wheel disc 32 is driven to rotate, so that different positions of the cable 200 are gradually attached to the lower edge of the main wheel disc 32, thereby realizing the coating of the cable 200.

[0055] Preferably, the preset immersion depth is 3 - 5 cm. By setting the suspension 70 to reach a certain preset immersion depth, it is ensured that the cable 200 can be immersed in the suspension 70 during the coating process, avoiding incomplete coating.

[0056] The guiding unit 30 further includes two sub-wheel discs 33 rotatably arranged in the coating space, and the two sub-wheel discs 33 are respectively located on both sides of the main wheel disc 32, and the cable 200 is wound around the upper edges of the sub-wheel discs 33. By setting the sub-wheel discs 33 to cooperate with the main wheel disc 32 to limit the local shape of the cable 200 to be V-shaped, the part of the cable 200 attached to the upper edges of the sub-wheel discs 33 does not contact the suspension 70, and the cable 200 can be smoothly coated and enter the metering space, which facilitates the setting of the metering unit 40.

[0057] In this embodiment, annular grooves are provided on the outer peripheral surfaces of the main wheel disc 32 and the sub-wheel discs 33 to accommodate the cable 200 to prevent the cable 200 from detaching; the cable 200 is conveyed by a traction device, and the main wheel disc 32 and the sub-wheel discs 33 are driven to rotate passively under the conveyance of the cable 200. The height of the main wheel disc 32 is lower than the heights of the two sub-wheel discs 33, and the heights of the two sub-wheel discs 33 are the same. The sizes and specific installation positions of the main wheel disc 32 and the sub-wheel discs 33 are not limited. It can be understood that the traction device can be set with reference to the prior art as long as it can realize the conveyance of the cable 200. The working principle of the traction device is the prior art and will not be elaborated here.

[0058] The cable coating device 100 further includes a bracket 10, the main body 21 is installed on the bracket 10, and the guiding unit 30 is partially installed on the bracket 10 and partially disposed in the accommodation space. Specifically, the guiding unit 30 further includes a main rotating shaft, a secondary rotating shaft, and a fixing seat 31. The fixing seat 31 is detachably connected to the bracket 10, and one or more fixing seats 31 can be provided; the main rotating shaft rotatably penetrates through the main body 21, one end of the main rotating shaft is non-detachably connected to the main wheel disc 32, and the other end of the main rotating shaft is rotatably connected to the fixing seat 31; the secondary rotating shafts are provided in one-to-one correspondence with the secondary wheel discs 33, one end of the secondary rotating shaft is connected to the secondary wheel disc 33 by a key connection or an interference fit to achieve synchronous rotation of the secondary rotating shaft and the secondary wheel disc 33, and the other end of the secondary rotating shaft is rotatably connected to the fixing seat 31.

[0059] In this embodiment, the bracket 10 is formed by splicing long strip-shaped materials with a rectangular cross-section. The bracket 10 can be made of wood or metal materials, such as steel; one main rotating shaft is provided, two secondary rotating shafts are provided, and three fixing seats 31 are arranged side by side. In other embodiments, one fixing seat 31 can also be provided, and the main rotating shaft and the secondary rotating shafts are separately rotatably connected to the same fixing seat 31.

[0060] Optionally, the stirring unit 50 includes a coil pipe 51, an air charging pipe 53, and a stirring throttle valve 52. The coil pipe 51 is disposed at the bottom of the coating space and immersed in the suspension 70. The coil pipe 51 is provided with air holes 511; one end of the air charging pipe 53 is communicated with the coil pipe 51 and the other end can be communicated with the second air charging system; the stirring throttle valve 52 is disposed on the air charging pipe 53 for adjusting the air flow rate of the air charging pipe 53. By setting the coil pipe 51 immersed in the suspension 70 and blowing air through the air holes 511 for disturbance, the uniformly distributed suspended powder can be ensured; by setting the stirring throttle valve 52 to adjust the air flow rate, it is beneficial to adjust to an appropriate stirring force, which is applicable to suspensions 70 with different powder contents. Of course, the stirring unit 50 can also be other implementation manners, such as stirring by a stirring rod, impact by a water pump, and vibration components.

[0061] In this embodiment, the air charging pipe 53 penetrates into the coating space from the side of the main body 21, and the stirring throttle valve 52 is disposed outside the coating space. In other embodiments, the stirring unit 50 can be a vibration component disposed outside the main body 21 for causing the main body 21 to vibrate so as to disturb the suspension 70, so as to avoid a large amount of deposition of talcum powder particles and affect the coating effect.

[0062] Specifically, both ends of the coil pipe 51 are communicated with the air charging pipe 53 through a three-way valve. The coil pipe 51 is located below the main wheel disc 32, and a plurality of air holes 511 are provided at intervals.

One end of the blowing pipe 43 is connected to the blower 41 and the other end can be connected to the first inflation system. The metering throttle valve 42 is arranged on the blowing pipe 43 for adjusting the air flow rate of the blower 41. By arranging the air flow to blow obliquely in the circumferential direction of the cable 200, the air flow is controlled to blow the suspension 70, so that the suspension 70 is evenly distributed along the surface of the cable 200 and the excess suspension 70 is blown off, realizing thin and light coating and ensuring the uniformity of coating.

[0064] In this embodiment, the cable 200 is sequentially conveyed through the guiding unit 30 and the blower 41. The part of the cable 200 between the guiding unit 30 and the blower 41 is an uneven coating section, and the part of the cable 200 between the blower 41 and the drying unit 60 is an even coating section. The air flow of the blower 41 blows the suspension 70 towards the uneven coating section. The cross-sectional area of the mounting hole of the partition plate 23 is larger than the cross-sectional area of the cable 200. Under the action of the blower 41, part of the suspension 70 passes through the mounting hole along the surface of the cable 200 and is blown into the coating space, and part of the suspension 70 is blocked by the partition plate 23 and thus remains in the metering space, and then flows back to the coating space through the gap between the bottom of the partition plate 23 and the body 21, which is beneficial to saving the amount of the suspension 70 used and reducing the coating cost.

[0065] In this embodiment, the first inflation system and the second inflation system work independently without interference, so as to facilitate the independent work of the metering unit 40 and the stirring unit 50.

The metering throttle valve 42 is arranged outside the metering space. A support plate is arranged in the body 21. The blower 41 is detachably arranged on the support plate to adapt to the height of the cable 200. Optionally, one or more blowers 41 can be arranged side by side along the extending direction of the cable 200. The cable 200 passes through the inside of all the blowers 41, and the cable 200 is conveyed through multiple blowers 41 for multiple air blowing to achieve a thinner and lighter coating effect.

[0066] The blower 41 is mainly used for air supply and can be set with reference to the prior art. The working principle of the blower 41 is the prior art. The drying unit 60 is used to dry the moisture of the suspension 70. The cable 200 passes through the inside of the drying unit 60. The drying unit 60 can be a drying heater. The drying unit 60 can also be set with reference to the prior art. The setting position of the cable 200 and the drying unit 60 can be selected according to the actual situation.
