Description

Technical Field

[0001] This utility model relates to the field of power cable processing technology, specifically a wire stranding machine for power cable processing. Background Technology

[0002] Power cables are cables used to transmit and distribute electrical energy. They typically consist of one or more insulated conductors, as well as their respective sheaths, overall protective layers, and outer protective layers, enabling efficient transmission and distribution of electrical energy in power systems.

[0003] In the field of power cable production, the stranding machine, as a key piece of equipment for stranding multiple single wires into cable cores, directly affects the quality and production efficiency of cables. Existing technologies, traditional stranding machines generally suffer from poor adaptability of the guiding mechanism and inconvenient axial adjustment: on the one hand, the fixed spacing of the guide rollers makes it difficult to adapt to cables of different diameters, requiring frequent equipment changes or manual adjustments, resulting in low efficiency and insufficient precision; on the other hand, the relatively fixed position of the guiding components prevents flexible adjustment of the axial distance, leading to inaccurate control of the stranding pitch and defects such as core misalignment and loosening. Furthermore, the equipment lacks coordinated adjustment functions, making it difficult to meet the production needs of diverse cable products. Utility Model Content

[0004] The purpose of this utility model is to provide a stranding machine for power cable processing, which solves the technical problem that the fixed spacing of the guide rollers makes it difficult to adapt to cables of different diameters, and achieves the purpose of adapting to cables of different diameters by adjusting the guide rollers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stranding machine for processing power cables, comprising a base, a controller disposed on the top of the base, a rotating component and a guiding component disposed on the top of the base, the rotating component being disposed on one side of the guiding component.

[0006] Preferably, the rotating assembly includes a protective shell, which is fixedly mounted on the top of the base.

[0007] Preferably, the protective shell has a circular hole inside, a motor is fixedly installed on one side of the protective shell, the output end of the motor is provided with a rotating shaft, the other end of the rotating shaft movably passes through one side of the outer wall of the protective shell, one side of the inner wall of the protective shell and extends to the other side of the inner wall of the protective shell, a gear is fixedly sleeved on the outer wall of the rotating shaft, and a connecting ring is movably sleeved inside the circular hole opened in the protective shell.

[0008] Motor 1 drives gear 1 to rotate via a shaft, and then the power is stably transmitted to the connecting ring through the meshing of gear 1 and gear 2, forming a gear transmission system.

[0009] Preferably, a second gear is fixedly sleeved on the outer wall of the connecting ring, and the second gear meshes with the first gear. A first stranding disc is fixedly sleeved on the inner wall of the connecting ring. A first connecting post is fixedly installed on both sides of the first stranding disc. A second stranding disc is fixedly installed at the other end of the first connecting post. A second connecting post is fixedly installed on the other side of the second stranding disc. A third stranding disc is fixedly installed at the other end of the second connecting post.

[0010] The first, second, and third stranding reels are rigidly connected by connecting posts, forming a three-layer coaxial rotating stranding system. Multiple cable cores pass sequentially through corresponding holes on the three layers of reels, achieving multi-stage stranding during rotation. Compared to a single-layer reel structure, this effectively reduces core sway and offset, significantly improves stranding stability, and makes the cable structure more compact and uniform.

[0011] Preferably, the guide assembly includes: an electric guide rail, fixedly installed on the top of the base; and a fixing plate, symmetrically and equidistantly fixedly installed on the top of the base.

[0012] Preferably, a slide block is slidably connected to the outer wall of the electric guide rail, and a connecting seat is fixedly sleeved on the outer wall of the slide block. Fixed plates are equidistantly arranged on both sides of the electric guide rail, and a guide rod is fixedly installed between the fixed plates. Movable plates are fixedly installed on both sides of the connecting seat, and the movable plates are slidably sleeved with the guide rods. An opening is provided inside the connecting seat, and sliding openings are provided on both sides of the connecting seat, communicating with the movable openings. A second fixed plate is symmetrically fixedly installed on one side of the outer wall of the connecting seat, and a third fixed plate is fixedly installed on the other side of the connecting seat. A second motor is fixedly installed on the top of the second fixed plate.

[0013] The guide system, consisting of the guide rod and the movable plate, forms a dual-guide structure with the electric guide rail, effectively limiting the shaking and offset of the connecting seat during movement.

[0014] Preferably, the output end of the second motor is provided with a bidirectional threaded rod, the other end of which movably passes through the top and bottom of the second fixed plate and extends to the top of another second fixed plate. The outer wall of the bidirectional threaded rod is symmetrically threaded to a movable plate. A guide rod is fixedly installed between the three fixed plates. The outer wall of the guide rod is symmetrically slidably fitted with a movable plate. A connecting shaft is fixedly installed between the two movable plates. Both ends of the connecting shaft are slidably connected to a connecting seat through sliding ports. A guide roller is rotatably fitted on the outer wall of the connecting shaft through a bearing. A connecting plate is symmetrically fixedly installed on the front of the connecting seat. A guide cylinder is fixedly installed between the connecting plates.

[0015] The second motor drives the bidirectional threaded rod to rotate. Utilizing its forward and reverse thread structure, the symmetrically connected movable plates can move synchronously towards or away from each other, thereby driving the third movable plate to slide on the guide rod, achieving precise adjustment of the guide roller spacing.

[0016] This utility model provides a stranding machine for processing power cables. It has the following advantages:

[0017] (1) This utility model drives the bidirectional threaded rod to rotate through the second motor, so that the two movable plates connected by symmetrical threads move towards each other or away from each other. The second movable plate drives the third movable plate to slide on the guide rod through the connecting shaft, and adjusts the spacing of the guide rollers in sync to achieve the effect of adapting to cables of different diameters.

[0018] (2) This utility model drives the slide block to move along the guide rail by electric guide rail, which drives the connecting seat to slide synchronously. The movable plate slides on the guide rod to ensure that the connecting seat moves smoothly and achieves the effect of adjusting the axial position of the guide component.
