[0044] In the process of coating the cable core wire, the cable core wire needs to be passed through the conveying hole 3, the coating mechanism, the clamping mechanism and the conveying mechanism in sequence. In the process of the cable core wire passing through the conveying hole 3, multiple positioning blocks 5 will squeeze and position the cable core wire, so that the cable core wire can be in the middle position of the conveying hole 3, ensuring that the position of the cable core wire can remain stable during the conveying process. The ends of multiple clamping rods 31 will fit with the surface of the cable core wire, and then the coating device is started. The driving motor 16 will drive the driving shaft 17 to rotate, and the rotation of the driving shaft 17 will drive the first bevel gear 18 to rotate together with the synchronous belt 29. The first bevel gear 18 will drive the rotating shaft 21 through the third bevel gear 22 to rotate together with the two fourth bevel gears 23, and the two fourth bevel gears 23 will act on the two The second bevel gear 19 rotates in the opposite direction, and the two second bevel gears 19 drive the two first driving wheels 10 to rotate through the two first rotating rods 9. The two first driving wheels 10 rotate in the opposite direction to transport the cable core wire in the groove 11 between the two first driving wheels 10 to the side away from the mounting plate 6. When the driving shaft 17 drives the synchronous belt 29 to rotate, the synchronous belt 29 drives the second rotating rod 26 and the second driving wheel 27 to rotate together, and the second driving wheel 27 acts on the driving ring 28 to rotate together. The rotation of the driving ring 28 drives the rotating ring 12 to rotate together, and the rotating ring 12 drives multiple winding rods 13 and the coating material 14 to rotate around the cable core wire. The coating material 14 wraps and covers the cable core wire, which controls the conveying speed and winding speed of the cable core wire. The speed correlation can make the coating material 14 better coat the cable core wire, ensure the coating effect of the coating material 14 on the cable core wire, and avoid that when the conveying speed of the cable core wire changes during the winding and coating process of the cable core wire, the coating speed of the cable core wire cannot be changed, which will cause the coating material 14 to be stacked or more scattered, thereby affecting the coating effect of the cable core wire. The blocking plate 15 can block the coating material 14 wound on the winding rod 13, and avoid that when the cable core wire is coated, the coating material 14 wrapped on the surface of the winding rod 13 will be pulled apart, thereby affecting the normal coating of the cable core wire. Subsequently, when replacing cable core wires of different thicknesses, the thickness of the cable core wire changes, and the clamping rod 31 fits the surface of the cable core wire after it is fitted The degree of inclination will change accordingly. After the degree of inclination of the clamping rod 31 changes, the telescopic plate 35 will slide on the surface of the base 1 under the action of the clamping rod 31. The movement of the telescopic plate 35 will drive the extension plate 36 and the pulling plate 37 to move together. The pulling plate 37 will act on the second driving wheel 27 to move. The movement of the second driving wheel 27 can adjust the contact position with the driving ring 28. The side of the driving ring 28 is an inclined surface. After the contact position of the second driving wheel 27 and the driving ring 28 changes, the diameter of the contact position of the second driving wheel 27 and the driving ring 28 will change. The transmission ratio of the second driving wheel 27 and the driving ring 28 will change accordingly. Subsequently, when the second driving wheel 27 acts on the driving ring 28 to rotate again at the same speed, the rotation speed of the driving ring 28 will change.The rotation speed of the rotating ring 12 can be changed according to the thickness of the cable core wire, thereby ensuring the coating effect of the coating material 14 on the cable core wire when the rotating ring 12 rotates.

[0045] In the process of coating the cable core wire, when the rotating ring 12 drives the winding rod 13 and the coating material 14 to rotate, there is no restriction on the rotation of the winding rod 13 and the coating material 14, and the coating material 14 cannot be tightly coated on the surface of the cable core wire. As a further solution of the present invention, a plurality of second fixing plates 38 are fixedly connected to the surface of the driving ring 28, and the second fixing plates 38 are located at the position of the winding rod 13. The surface of the second fixing plate 38 is elastically slidably connected to a limiting plate 39, and the limiting plate 39 is in contact with the surface of the coating material 14.

[0046] During the process of wrapping the cable core wire, the rotating ring 12 and the driving ring 28 will drive the winding rod 13 and the wrapping material 14 to rotate together, and the limiting plate 39 will squeeze and limit the wrapping material 14, so that the wrapping material 14 can be restricted by the limiting plate 39 when rotating, so that the wrapping material 14 can have a certain tensile force when wrapping the cable core wire, thereby ensuring the tightness of the wrapping material 14 when wrapping the cable core wire.

[0047] In the process of coating the cable core wire, the edge of the coated coating material 14 will be lifted up, which is easy to affect the stability of the clamping rod 31. As a further solution of the present invention, a pressure plate 40 is elastically hinged on the surface of the rotating ring 12, and the end of the pressure plate 40 is arc-shaped, and the end of the pressure plate 40 is in contact with the surface of the coated cable core wire;

[0048] During the process of coating the cable core wire, the cable core wire will pass through the pressure plate 40, and the ends of multiple pressure plates 40 will fit with the surface of the coated cable core wire. Then, during the movement of the cable core wire, the pressure plate 40 can press down and smooth the coating material 14 coated on the surface of the cable core wire, so that the coated coating material 14 can fit tightly with the cable core wire, avoiding the edge of the coating material 14 after coating the cable core wire from curling up, which will affect the stability of the clamping rod 31, thereby causing the clamping rod 31 to move and drive the second drive wheel 27 to move, affecting the stable transmission of the second drive wheel 27 and the drive ring 28.

[0049] In the process of coating the cable core wire, when the coating material 14 is gradually reduced, the blocking plate 15 will affect the extension of the coating material 14. As a further solution of the present invention, the bottom of the blocking plate 15 is bent away from the mounting plate 6;

[0050] During the process of coating the cable core wire, the coating material 14 will gradually decrease, and the diameter of the reduced coating material 14 will be smaller than the diameter of the blocking plate 15. When the coating material 14 is pulled out, it will fit with the bending position at the bottom of the blocking plate 15, so that the coating material 14 can extend along the bending position at the bottom of the blocking plate 15, thereby ensuring the coating effect of the coating material 14 on the cable core wire.

[0051] A method for coating a core wire of an electric wire and cable, the specific steps of the method are as follows:

[0052] Step 1: In the process of coating the cable core wire, the cable core wire needs to be first passed through the conveying hole 3 and installed in the coating device, and the clamping device will clamp the cable core wire to keep it stable;

[0053] Step 2: Then start the covering device, and the driving mechanism will act on the conveying mechanism to convey the cable core wire;

[0054] Step 3: The driving mechanism will act on the covering mechanism to cover the cable core wire;

[0055] Step 4: When it is necessary to coat cable cores of different thicknesses, after replacing the cable cores of different thicknesses, the adjustment mechanism will adjust the rotation speed of the coating mechanism according to the thickness of the replaced cable cores.
