Description

Technical Field

[0001] This utility model relates to the field of stranded wire winding technology, specifically a high-efficiency winding drum for copper-clad steel stranded wire. Background Technology

[0002] Copper-clad steel stranded wire is made of a certain number of copper-clad steel single wires stranded together. It is widely used in high-frequency coaxial cables, steel-network communication, electrified railways, subways and light rails, railways, airports, network communications and other places for lightning protection grounding, anti-static grounding, protective grounding, and grounding wires in power and petrochemical systems.

[0003] After copper-clad steel stranded wire is manufactured, it often needs to be wound into drums for convenient transportation and use. However, existing drums and their winding technology often involve inserting the drum into a drive shaft, which then drives the drum to rotate. This process is not only time-consuming to install, but also extremely difficult to disassemble from the drive shaft after winding, especially as the weight of the drum increases.

[0004] An existing patent discloses a textile fabric winding roller (publication number CN208648306U), which effectively solves the problem of wrinkles easily generated during current winding processes. The solution includes a frame with a first roller horizontally mounted at one end along the front-to-back direction. Two sets of extension devices are symmetrically arranged on the left side of the first roller. Each set includes two second rollers arranged vertically side-by-side. The outer walls of the two second rollers are in elastic contact and are perpendicular to the first roller. The two second rollers can rotate simultaneously in opposite directions, with the linear velocity of the contact point outwards. The technology disclosed in this patent involves inserting the roller into a drive shaft, followed by installation and transmission along with the drive shaft. This process is not only time-consuming and labor-intensive but also poses significant safety hazards. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a high-efficiency winding drum for copper-clad steel strands, solving the problems mentioned in the background section.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, a high-efficiency winding drum for copper-clad steel strand includes two side frame plates, a winding wheel, and a bottom plate installed below the side frame plates. A first rotating roller and a second rotating roller that can rotate freely are provided between the two side frame plates. An inclined plate is fixedly installed between the two side frame plates and at the right end of the second rotating roller.

[0007] Both of the side frame plates have drive wheels that can rotate freely through their outer surfaces. The drive wheels house extrusion heads that can move left and right. A central cross post is fixedly connected to the back of the extrusion head. The drive wheels have a middle partition plate inside, with the central cross post extending to the other side of the middle partition plate and fitted with an extrusion spring and a fixing disc.

[0008] Furthermore, the bottom end of the inclined plate contacts the bottom plate, and the inclined plate coincides with the tangent on the outer surface of the second rotating roller.

[0009] Furthermore, a drive motor is mounted on the surface of the bottom plate, and the output shaft of the drive motor is fitted with a first gear.

[0010] Furthermore, a drive shaft is rotatably arranged between the two side frame plates, and a second gear is sleeved on the surface of the drive shaft, wherein the second gear meshes with the first gear.

[0011] Furthermore, both ends of the drive shaft extend to the surface of the side frame plate and are fitted with small drive wheels. The drive wheel includes an inner rotating disc and an outer large drive wheel, wherein the surfaces of the large and small drive wheels on the outer side of the drive wheel are fitted with drive belts.

[0012] Furthermore, a U-shaped frame is fixedly installed on the surface of both side frame plates. A threaded push rod is threadedly connected to the center of the U-shaped frame. The inner end of the threaded push rod is conical, and four rotating rods are installed on the outer end. The conical end of the threaded push rod is in pressure contact with the outer surface of the fixed disc.

[0013] The beneficial effects of this utility model of a high-efficiency winding drum for copper-clad steel strand are as follows:

[0014] (1) This utility model uses an empty take-up wheel to be pushed above two rotating rollers by a ramp, and then the extrusion head is clamped on the take-up wheel and the drive motor drives the take-up wheel to rotate, so as to achieve the purpose of winding the twisted wire. The finished take-up wheel can be pushed down from the ramp, which can greatly improve the speed of installing and unloading the take-up wheel.

[0015] (2) By rotating the threaded push rod, the tip of the threaded push rod can be used to squeeze the fixed disc. The fixed disc will then push the extrusion head through the central cross post, so that the extrusion head can be locked in the cavity of the take-up wheel. This allows the take-up wheel to be fixed between the two drive wheels quickly and efficiently, and the rotation of the fixed disc will not affect the extrusion of the threaded push rod.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0024] like Figure 1-5 As shown, according to one aspect of this utility model, a high-efficiency winding drum for copper-clad steel strand is provided, comprising two side frame plates 1, a winding wheel 2, and a bottom plate 3 installed below the side frame plates 1. A first rotating roller 12 and a second rotating roller 13, which can rotate freely, are provided between the two side frame plates 1. An inclined plate 15 is fixedly installed between the two side frame plates 1 and at the right end of the second rotating roller 13. Figure 2 , 4 As shown), the inclined plate 15 is used to facilitate pushing the empty winding wheel 2 above the two rotating rollers, or to remove the winding wheel 2 containing the stranded wire from the rotating rollers. This design facilitates the installation and unloading of the winding wheel 2.

[0025] Both side frame plates 1 have drive wheels 5 that can rotate freely through their outer surfaces. Inside each drive wheel 5 is a pressing head 14 that can move left and right. A central cross post 17 is fixedly connected to the back of each pressing head 14. Inside each drive wheel 5 is a middle partition plate, with the central cross post 17 extending to the other side of the middle partition plate and fitted with a pressing spring 16 and a fixing disc 18 (e.g., ...). Figure 3 , 5As shown), the compression spring 16 can ensure that the compression head 14 has an inward tendency, so that when the threaded push rod 7 stops compressing the fixed disc 18, the compression head 14 can be withdrawn from the winding wheel 2 in time.

[0026] In this embodiment, the bottom end of the inclined plate 15 contacts the bottom plate 3, and the tangent of the inclined plate 15 coincides with the outer surface of the second rotating roller 13 (e.g., Figure 4 As shown), the tilt angle of this swashplate 15 allows the take-up roller 2 to be easily pushed above the two rotating rollers.

[0027] In this embodiment, a drive motor 10 is mounted on the surface of the bottom plate 3, and a first gear 11 is sleeved on the output shaft of the drive motor 10. A transmission shaft 20 is rotatably arranged between the two side frame plates 1, and a second gear 19 is sleeved on the surface of the transmission shaft 20, wherein the second gear 19 meshes with the first gear 11 (e.g., ...). Figure 4 As shown, the diameter of the first gear 11 is much smaller than that of the second gear 19, which increases the torque of the second gear 19.

[0028] In this embodiment, both ends of the drive shaft 20 extend to the surface of the side frame plate 1 and are fitted with small drive wheels 9. The drive wheel 5 includes an inner rotating disc and an outer large drive wheel. The large drive wheel and the small drive wheel 9 on the outer side of the drive wheel 5 are fitted with a drive belt 8.

[0029] In this embodiment, a U-shaped frame 4 is fixedly installed on the surface of both side frame plates 1. A threaded push rod 7 is threadedly connected to the center of the U-shaped frame 4. The inner end of the threaded push rod 7 is tapered, and four rotating rods 6 are installed on the outer end. The tapered end of the threaded push rod 7 is in pressure contact with the outer surface of the fixed disc 18 (e.g., Figure 3 As shown), the pointed cone end of the threaded push rod 7 can both press the fixed disk 18 and not hinder the rotation of the fixed disk 18.

[0030] The working principle of this device is as follows: the empty take-up reel 2 is pushed from the right end along the inclined plate 15 into the device (e.g., Figure 2 , 4 As shown), the empty take-up reel 2 can be placed above the first drive roller 12 and the second drive roller 13. At this time, if the take-up reel 2 rotates freely, the first drive roller 12 and the second drive roller 13 will also rotate with the take-up reel 2.

[0031] Then, rotating the rotating rod 6 drives the threaded push rod 7 to rotate, thereby causing the tip of the threaded push rod 7 to press against the fixed disc 18 (e.g., Figure 1 , 3As shown), the fixed disc 18 will cause the extrusion head 14 to extrude the middle cavity of the take-up roller 2 through the central cross post 17. In this way, the take-up roller 2 will be fixed between the two drive wheels 5. When the two drive wheels 5 rotate, they can drive the take-up roller 2 to rotate.

[0032] When the drive motor 10 is started, it drives the transmission shaft 20 to rotate through the first gear 11 and the second gear 19. The small transmission wheels 9 located at both ends of the transmission shaft 20 will then drive the two drive wheels 5 to rotate synchronously through the transmission belt 8 (e.g., Figure 1 As shown), this allows the drive motor 10 to rotate the take-up wheel 2 to achieve the purpose of winding the twisted wire. And after winding is complete, simply release the threaded push rod 7 from the fixed disc 18, and the compression head 14 will also separate from the take-up wheel 2 under the action of the compression spring 16 (as shown). Figure 3 As shown in the figure, at this time the winding wheel 2 with the twisted wire can be pushed off the inclined plate 15.

[0033] Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
