The second driving wheel 27 is in contact with the side of the driving ring 28. The second rotating rod 26 and the surface of the drive shaft 17 are jointly connected by a synchronous belt 29.

[0042] The clamping mechanism includes a plurality of fixing rods 30, which are fixedly connected to the surface of the mounting plate 6 on one side close to the rotating ring 12. The plurality of fixing rods 30 are arranged at equal angles around the mounting opening 7. The ends of the fixing rods 30 are elastically hinged with clamping rods 31. The ends of the clamping rods 31 are arc-shaped, and the ends of the clamping rods 31 are in contact with the surface of the cable core wire.

[0043] The adjusting mechanism includes a sliding groove 32, a plurality of sliding grooves 32 are all provided on the surface of the second rotating rod 26, the second driving wheel 27 slides in the sliding groove 32, and the left and right surfaces of the second driving wheel 27 are rotatably connected with a stop plate 33, and a spring 34 is connected between the stop plate 33 close to the side of the support plate 25 and the support plate 25, and the surface of the clamping rod 31 at the bottom is hinged with a telescopic plate 35, and the bottom of the telescopic plate 35 slides on the surface of the base 1, and one side of the telescopic plate 35 is fixedly connected to an extension plate 36, and the end of the extension plate 36 extends to the bottom of the rotating ring 12, and the surface of the extension plate 36 is fixedly connected to a pulling plate 37, which extends into the expansion groove 24, and the pulling plate 37 is located on the outer side of the expansion groove 24 and is retractable. One end of the pulling plate 37 is located in the expansion groove 24 and is located on the side of the second driving wheel 27 away from the support plate 25, and the pulling plate 37 is used to act on the second driving wheel 27 to move;

[0044] In the process of wrapping the cable core wire, the cable core wire needs to be passed through the conveying hole 3, the wrapping 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 wrapping device will be 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 and the synchronous belt 29 to rotate together. The first bevel gear 18 will rotate together with the two fourth bevel gears 23 through the third bevel gear 22. 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 will 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 will drive the second rotating rod 26 and the second driving wheel 27 to rotate together, and the second driving wheel 27 will act on the driving ring 28 to rotate together. The rotation of the driving ring 28 will drive the rotating ring 12 to rotate together, and the rotating ring 12 will drive multiple winding rods 13 and the coating material 14 to rotate around the cable core wire. The coating material 14 will wrap and cover the cable core wire, which will control 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 in the process of winding and coating the cable core wire, when the conveying speed of the cable core wire changes, the coating speed of the cable core wire cannot be changed, which will cause the coating material 14 to be stacked or more dispersed, 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 in the process of coating the cable core wire, the coating material 14 wound 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, after the thickness of the cable core wire changes, the clamping rod 31 is in contact with the surface of the cable core wire. The degree of inclination will change as the inclination of the clamping rod 31 changes, the telescopic plate 35 will slide on the surface of the download base 1 under the action of the clamping rod 31, and the movement of the telescopic plate 35 will drive the extension plate 36 and the pulling plate 37 to move together, and 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, and the transmission ratio of the second driving wheel 27 and the driving ring 28 will change together. 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 and the rotation 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 covering effect of the covering 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, the winding rod 13 and the coating material 14 are not restricted in rotation, 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. The second fixing plates 38 are located at the position of the winding rod 13. The surface of the second fixing plates 38 is elastically and slidably connected to the limiting plates 39. The limiting plates 39 are 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, ensuring the tightness of the wrapping material 14 when wrapping the cable core wire.

[0047] During the process of coating the cable core, the edges of the coating material 14 will warp, which may easily 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;

[0048] During the process of wrapping 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 cable core wire after wrapping. Then, during the movement of the cable core wire, the pressure plate 40 can press down and smooth the wrapping material 14 after wrapping the surface of the cable core wire, so that the wrapping material 14 can fit tightly with the cable core wire, avoiding the edge of the wrapping material 14 after wrapping 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] During the process of coating the cable core, 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 wrapping the cable core wire, the wrapping material 14 will gradually decrease, and the diameter of the reduced wrapping material 14 will be smaller than the diameter of the blocking plate 15. When the wrapping material 14 is pulled out, it will fit with the bending position at the bottom of the blocking plate 15, so that the wrapping material 14 can extend along the bending position at the bottom of the blocking plate 15, thereby ensuring the wrapping effect of the wrapping 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: During the process of sheathing the cable core wire, the cable core wire needs to be passed through the conveying hole 3 and installed in the sheathing device. 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 cover cable cores of different thicknesses, after replacing the cable cores of different thicknesses, the adjustment mechanism will adjust the rotation speed of the covering mechanism according to the thickness of the replaced cable cores.
