Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a pressure-resistant and corrosion-resistant coaxial cable graphite coating device, comprising an equipment body 1, a coating mechanism is arranged inside the equipment body 1, a feeding mechanism is arranged on the top of the equipment body 1, a drying box 17 is arranged on the right side of the coating mechanism, and the drying box 17 is installed on the equipment body 1.

[0025] like Figure 2 and 3As shown, the unloading mechanism includes a support frame 16, which is installed on the equipment body 1, and a stirring box 12 is installed on the top of the support frame 16. A stirring motor 14 and a feeding pipe 15 are installed on the top of the stirring box 12. A stirring blade 13 is installed on the output end of the stirring motor 14, and a unloading pipe 10 is installed at the bottom of the stirring box 12. A flow control valve 11 is installed above the outer wall of the unloading pipe 10. The lower end of the unloading pipe 10 passes through the top of the equipment body 1 and is installed with a unloading head 9. The stirring blade 13 is arranged inside the stirring box 12. By controlling the rotation of the stirring motor 14, the stirring blade 13 at the output end is driven to rotate together, and then the flow control valve 11 is controlled to control the flow of the paint, and the paint enters the interior of the unloading head 9 through the unloading pipe 10 and flows to the cable surface, waiting for the next step of coating the plate 8 to be operated.

[0026] The working principle is as follows: during the cable feeding process, the utility model controls a sufficiently long coating plate 8 to repeatedly coat the cable surface 360 ​​degrees, so that the graphite coating can be evenly coated on the cable surface. When in use, the coating is first poured into the interior of the stirring box 12 through the feeding pipe 15. Since the feeding speed needs to be controlled, in order to prevent the coating from forming particles inside the stirring box 12, the stirring motor 14 is controlled to rotate while feeding, driving the stirring blade 13 at the output end to rotate together, and then the coating flow rate is controlled by controlling the flow control valve 11, and the coating enters the interior of the feeding head 9 through the feeding pipe 10 and The paint flows to the surface of the cable, and at the same time, the driving motor 5 is controlled to rotate, driving the active wheel 6 at the output end to rotate together, and the gear ring 3 is used to drive the slider to make a circular motion along the outer wall of the annular guide rail 4, and the connecting plate 7 and the coating plate 8 are driven to make a circular motion on the cable surface, so that the paint follows the material feeding, and the coating plate 8 evenly coats the paint on the cable surface in a circular motion. At the same time, before discharging, the paint just applied on the cable surface is dried by the drying box 17, so that the paint is quickly fixed on the cable surface, so that the cable surface has a higher flatness and better quality after discharging.

At the same time, the paint stored in the storage box 19 is re-conveyed to the inside of the mixing box 12 through the feeding pipe 21 for stirring and reuse by controlling the pump body 20, thereby reducing the investment in production costs.

[0029] like Figure 2 and 4 As shown, two fixed plates 22 are installed on the left and right side surfaces of the equipment body 1, and a hollow plate 23 is installed on one side of the two fixed plates 22.
