Description

Technical Field

[0001] This utility model relates to a self-traction type transfer shaft for semi-finished cables, belonging to the field of cable production technology. Background Technology

[0002] Cable manufacturing workshops commonly employ continuous, assembly-line operations. Between processes such as extrusion, cutting, branching, and subsequent testing, semi-finished cables must be stably and continuously pulled from the current workstation to the next to ensure a smooth transition in production. This is especially critical in high-volume, long-distance production environments, where the reliability, ease of operation, and maintenance efficiency of the pulling device are of paramount importance.

[0003] In existing technologies, the inter-station traction of semi-finished cables mostly relies on independent traction rigging or scrap stranded wire, combined with simple rollers or turntables. The common practice is to manually tie one end of the traction line to the cable end, and the other end to the outside of the roller or turntable. Then, at the next station, the rigging is manually removed or the old wire is cut before re-tying. The rollers used typically only have basic winding functions and lack dedicated traction line storage or quick-change structures; the traction rigging is often replaced with other scrap wire, resulting in a limited lifespan and a high risk of breakage.

[0004] Therefore, it is necessary to design a cable semi-finished product traction transfer shaft to solve the problems of easy breakage of traction wires, inconvenient maintenance, and easy breakage of cables during winding in traditional technology. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cable semi-finished product traction transfer shaft, which solves the problems of easy breakage of traction wire, inconvenient maintenance, and easy breakage of cable during winding.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: a self-traction transfer shaft for semi-finished cables, comprising...

[0007] A hinge capable of accommodating cables;

[0008] Side plates, which are disposed on both sides of the pivot and provide symmetrical support.

[0009] The surface of the shaft includes a threaded groove area and a smooth glazed area, with grooves arranged around the threaded groove area.

[0010] The surface of the threaded groove area is provided with a traction line. One end of the traction line can be connected to guide the product, and the other end is connected to one end of the rotating shaft through a hook.

[0011] The threaded groove area is provided with an installation part, and the connection point of the traction line and the cable can be set in the groove.

[0012] Preferably, the traction line and the cable are connected at their ends by knotting, and the connection point can be located inside the mounting section.

[0013] Preferably, the traction line is disposed on the side of the threaded groove area away from the smooth glaze area.

[0014] Preferably, the traction line can be wound within the threaded groove area.

[0015] Preferably, when the traction wire is wound around the threaded groove area, its height is flush with the smooth glazed area.

[0016] Preferably, the connecting assembly includes a hanging ring and a hook, the hanging ring being disposed on the surface of the rotating shaft, and the hook being disposed at one end of the traction line.

[0017] Preferably, the surface of the traction line is provided with an ETFE coating.

[0018] The beneficial effects of this utility model are:

[0019] This invention connects the traction cable to the rotating shaft via a connecting assembly, which uses a hook and a hanging ring for engagement. A threaded groove is provided on the surface of the rotating shaft to accommodate the traction cable, ensuring it remains in a fixed position. The end of the traction cable is connected to the semi-finished cable via a knot, with the knot positioned within the mounting section of the rotating drum to reduce cable stretching and prevent breakage. The traction cable can be quickly assembled and disassembled using the connecting assembly, facilitating maintenance.

[0020] This invention provides a smooth glazed area on the rotating shaft, which reduces the coefficient of friction of the cable when it passes through the smooth glazed area, thereby reducing the risk of jamming and wire breakage. It is applicable to various cable outer sheaths.

[0021] In this invention, the rotating shaft and the side plate are fixed together by welding. Holes are provided on the axis of the rotating shaft and the side plate for positioning. During winding, the rotating shaft can be lifted through the holes for easy rotation. After winding, the side plate allows for rapid transfer. The traction wire is connected by a connecting assembly for quick disassembly and replacement. Furthermore, the surface of the traction wire is coated with ETFE, allowing for relatively quick detachment from the threaded groove area for easy maintenance. Attached Figure Description

[0027] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0028] like Figures 1-4 As shown, a self-traction type pivot for semi-finished cables includes a pivot 1 and side plates 2. The pivot 1 can accommodate the pivot, and there are two side plates 2, which are symmetrically arranged on both sides of the pivot 1. The side plates 2 can provide support.

[0029] In this embodiment, the rotating shaft 1 and the side plate 2 are an integral structure. A hole is provided at the center of the side plate 2 and the rotating shaft 1. The hole passes through the rotating shaft, and the position of the rotating shaft can be fixed through the hole during the production process.

[0030] The rotating shaft 1 is a hollow cylinder, and its surface is divided axially into a threaded groove area 11 and a smooth glazed area 13. A mounting part 12 is provided at the end of the threaded groove area 11 and at the dividing line of the smooth glazed area 13. The two ends of the rotating shaft 1 are connected to the side plate 2 by welding, and the rotating shaft 1 can rotate around the axis.

[0031] The threaded groove area 11 consists of several spiral grooves equidistantly arranged along the surface of the rotating shaft 1. The groove depth and pitch match the outer diameter of the traction wire 3, ensuring that the traction wire 3 can be wound around the spiral grooves.

[0032] Once the traction line 3 is connected to the end of the cable that needs to be pulled, the cable can be quickly and smoothly released or wound from the spool through spiral guidance.

[0033] The edge of the threaded groove area 11 is located on one side of the rotating shaft 1, extending one end distance towards the center of the rotating shaft 1. A mounting part 12 is provided at the end of the threaded groove area 11. The mounting part 12 is an elliptical groove provided on the surface of the rotating shaft 1. The edge of the groove is rounded. The wire diameter is larger at the connection point of the traction wire 3 and the cable. The connection point can be placed in the mounting part 12 to ensure that the connection point of the traction wire 3 and the cable can be fixed in the spiral groove of the rotating shaft. This prevents displacement when the cable is wound in the rotating shaft 1 and provides storage space for the connection point of the traction wire 3 and the cable after winding, reducing the impact of the connection point on the cable wound subsequently.

[0034] The area on the spindle 1, excluding the mounting section 12 and the threaded groove area 11, is a smooth glazed surface area 13. This smooth glazed surface area 13 is a smooth cylindrical surface with a glaze layer. The top surface of the smooth glazed surface area 13 is flush with the peak of the threaded groove area 11, without any protrusion. When the spindle 1 winds a cable into this smooth glazed surface area 13, the coefficient of friction between the cable and the spindle is low, reducing frictional loss during cable unwinding.

[0035] Side plate 2 is a disc coaxially symmetrical with shaft 1. The inner diameter of side plate 2 matches the outer diameter of shaft 1. Side plate 2 and shaft 1 are connected and fixed by welding. Side plate 2 ensures that when shaft 1 is on the ground, it only contacts the ground through side plate 2, and shaft 1 and the cable it carries do not come into contact with the ground.

[0036] The hole provided at the center of the side plate 2 and the rotating shaft 1 can fix the entire rotating shaft to the bracket or frame of the production equipment 1.

[0037] In this embodiment, a traction line 3 is provided in the threaded groove area 11 on the rotating shaft 1, and the traction line 3 is connected to the rotating shaft 1 through a connecting assembly. In this embodiment, the connecting assembly includes a hook 31 and a hanging ring 14. The diameter of the traction line 3 is slightly smaller than the groove depth of the threaded groove area 11, and an ETFE coating is provided on the surface of the traction line 3.

[0038] A hook 31 is provided at one end of the traction line 3. The hook 31 is fixed to the traction line 3 by welding. The other end of the traction line 3 can be knotted and wrapped with the cable. The knot can be set inside the mounting part 12.

[0039] A hanging ring 14 is located on the side of the threaded groove area 11 of the rotating shaft 1, near the side plate 2. The hanging ring 14 is welded to the beginning of the thread in the threaded groove area 11. The traction line 3 is connected to the surface of the rotating shaft 1 by engaging with the hanging ring 14 via a hook 31. The traction line 3 can be wound around the threaded groove area 11, and its end is knotted with a cable. The knot can be located within the mounting part 12 to reduce the increase in wire diameter at the knot and minimize its impact on subsequent cable winding.

[0040] The traction line 3 can be quickly disconnected from the rotating shaft 1 via the hook 31, facilitating subsequent operations. At the start of production, the end of the traction line 3 without the hook 31 is connected to the cable by a knot. Subsequently, the traction line 3 can be quickly connected to the rotating shaft 1 via the hook 31, placing the traction line 3 within the threaded groove area 11 and guiding the cable to wind onto the turntable 1.

[0041] In this embodiment, the rotating shaft 1 is connected to the side plate 2 by welding; the traction line 3 is connected to one end of the rotating shaft 1 through a connecting component, and the traction line 3 can be wound and disposed in the threaded groove area 11.

[0042] When production begins, the entire assembly can be secured through the holes on the axis of the side plate 2. The semi-finished cable can be fixed to the end of the traction line 3 without the hook 31 by knotting. Rotating the shaft 1 allows the traction line 3 to be positioned within the threaded groove area 11. The knot between the traction line 3 and the cable is located at the mounting part 12, after which the cable continues to wind around the reel 1. The semi-finished cable is then positioned on the shaft 1.

[0043] When the semi-finished cable mounted on the rotating shaft 1 needs further processing, rotating the rotating shaft 1 can disconnect the semi-finished cable from the rotating shaft 1, and the knot between the semi-finished cable and the traction line 3 can be removed, thus completing the disconnection of the semi-finished cable. Furthermore, the surface of the traction line 3 is coated with ETFE, allowing it to be quickly detached from the threaded groove area 11. By adjusting the hook 31, the traction line 3 can be disconnected from the rotating shaft 1.

[0044] The semi-finished cables experience less friction on the smooth glazed area 13, preventing cable breakage and jamming, thus improving the yield rate. When the semi-finished cables are placed on the reel 1, the side plate 2 supports the reel 1, improving storage flexibility and storage time.

[0045] Reference Figure 4 The traction wire and the semi-finished cable are connected by knotting. The knot can be located inside the mounting part 12 without affecting the subsequent winding of the semi-finished cable.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
