[0031] Reference Figures 1 to 5 A double-core winding core rod of an embodiment of the present application comprises an outer core rod 100 and an inner core rod 200.

[0032] Specifically, a plurality of first wear-resistant plates 110 are arranged at intervals along the circumference of the outer core rod 100, and the first wear-resistant plates 110 can be uniformly distributed on the outer peripheral wall of the outer core rod 100. For example, four first wear-resistant plates 110 are uniformly distributed on the outer peripheral wall of the outer core rod 100, and the first wear-resistant plates 110 can be arranged in sections along the axial direction of the outer core rod 100, for example, an upper section, a middle section and a lower section are arranged in sequence from top to bottom. In addition, a through channel (not shown in the drawings) is provided in the middle of the outer core rod 100, and a sliding groove 111 is provided on the first wear-resistant plate 110 and communicates with the through channel.

[0033] The inner core rod 200 is slidably arranged in the through channel, one end of the inner core rod 200 is provided with a lifting portion 210, the size of the lifting portion 210 is greater than the size of the through channel, and the lifting portion 210 can prevent the inner core rod 200 from falling out of the lower part of the outer core rod 100. When the high-speed wire rod is unloaded, the first wear-resistant plate 110 is completely inserted into the sliding groove 111, at this time the inner core rod 200 will not be pulled out of the outer core rod 100 when the winding trolley unloads. At the same time, when the inner core rod 200 moves upward relative to the outer core rod 100, the lifting portion 210 can be pushed below the nose cone of the winding drum, which can support the nose cone. A second wear-resistant plate 220 is arranged in the circumferential direction of the end of the inner core rod 200 close to the lifting portion 210 and is slidably connected with the sliding groove 111, so that when the inner core rod 200 moves upward relative to the outer core rod 100, the second wear-resistant plate 220 is located in the transition region between the lifting portion 210 and the outer core rod 100, which can prevent the wire rod falling in the winding drum from damaging the inner core rod. In addition, in order to prevent the inner core rod 200 from being completely pulled out of the upper part of the outer core rod 100, a limiting portion is arranged on the second wear-resistant plate 220 and matched with the sliding groove 111, and the limiting portion can prevent the second wear-resistant plate 220 from being separated from the sliding groove 111.

[0034] In some embodiments, as Figure 3As shown, at least one chute 111 penetrates the first wear plate 110 away from the side where the passage is communicated. Exemplarily, four first wear plates 110 are evenly distributed on the outer peripheral wall of the outer core rod 100, and the side wall of one of the first wear plates 110 is not covered with wear-resistant plate material, so that the height difference between the first wear plate 110 and the second wear plate 220 is reduced, avoiding affecting the smooth falling of the wire.

[0035] In order to further facilitate the smooth falling of the wire, in some embodiments, as shown in Figure 2 As shown, the closed side of the chute 111 that does not penetrate the first wear plate 110 away from the side where the passage is communicated is inclinedly arranged near one end of the jacking part 210, and the inclination direction is towards the side of the jacking part 210. Exemplarily, four first wear plates 110 are evenly distributed on the outer peripheral wall of the outer core rod 100, and the side wall of three of the first wear plates 110 is covered with wear-resistant plate material of a certain thickness. At this time, due to the inclined arrangement of the wear-resistant plate material, the height difference between the first wear plate 110 near the jacking part 210 and the second wear plate 220 is reduced, so that the wire can fall smoothly, avoiding the head or tail of the high-speed wire being stuck in this transition area.

[0036] In order to further facilitate the smooth falling of the wire, in some embodiments, as shown in Figure 2 As shown, the closed side of the chute 111 and the transition area of the jacking part 210 are provided with a wedge surface 1111. Exemplarily, four first wear plates 110 are evenly distributed on the outer peripheral wall of the outer core rod 100, and the side wall of three of the first wear plates 110 is covered with wear-resistant plate material of a certain thickness. The wedge surface 1111 is arranged near the outlet of the wear-resistant plate material of the chute 111, so that the transition between the first wear plate 110 near the jacking part 210 and the second wear plate 220 is gentle and has fewer corners, so that the wire can fall smoothly, avoiding the head or tail of the high-speed wire being stuck in this transition area.

[0037] In some embodiments, the wedge surface 1111 is consistent with the width of the closed side of the chute 111, avoiding the head or tail of the high-speed wire being stuck on the first wear plate 110 when the high-speed wire is unloaded.

[0038] In order to ensure that the first wear plate 110 has strong supporting capacity, especially when the inner core rod 200 moves upward relative to the outer core rod 100. For this purpose, in some embodiments, as shown in Figure 2 , Figure 5 As shown, the first wear plate 110 is provided with a reinforcing plate 112 near one end of the jacking part 210.

[0039] In some embodiments, as shown in Figure 4As shown, the second wear plate 220 is provided with a clamping plate 221 at one end away from the jacking portion 210, and the clamping plate 221 forms a limiting portion on the second wear plate 220 which matches the sliding groove 111. Specifically, the height of the clamping plate 221 is higher than the height of the second wear plate 220, and correspondingly, the size of the one end of the sliding groove 111 away from the jacking portion 210 matches the size of the clamping plate 221. When the inner core rod 200 moves upward relative to the outer core rod 100, the clamping plate 221 cannot continue to move upward after moving to a certain height in the sliding groove 111, so that the second wear plate 220 can be prevented from being separated from the sliding groove 111.

[0040] In some embodiments, as shown in Figure 2 , Figure 5 As shown, the first wear plate 110 protrudes from the end of the outer core rod 100 at one end close to the jacking portion 210, and when the second wear plate 220 is completely located in the sliding groove 111, the height of the protruding first wear plate 110 is greater than the height of the jacking portion 210. In this way, when the coil car unloads the coil, the high-speed wire cannot pull the inner core rod 200, so that the inner core rod is prevented from being pulled out of the outer core rod 100.

[0041] In some embodiments, as shown in Figure 2 As shown, the jacking portion 210 is circular in shape, which can reduce the generation of edges and corners and avoid being pulled by high-speed wires.

[0042] In some embodiments, as shown in Figure 2 As shown, the jacking portion 210 is circular in shape, which can reduce the generation of edges and corners and avoid being pulled by high-speed wires.

[0043] The above are only preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
