Description

Technical Field

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

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. The manufacturing process of power cables involves using a stranding machine to twist two insulated conductors together. Through stranding, twisted-pair cables are produced, which have better bending resistance and electronic signal interference immunity.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] Existing cable stranding machines cause significant friction when the cable raw material passes through the guide disc during cable stranding, leading to wear on the surface of the cable raw material as the guide disc rotates and strands the wire, thus reducing the cable's conductivity.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] The purpose of this invention is to provide a wire stranding machine for power cable processing, so as to solve the problems mentioned in the background art.

[0007] By adopting the above technical solution, the problem of reduced cable conductivity caused by wear on the surface of the cable raw material due to the large friction when the cable raw material passes through the guide wire disc and the guide wire disc rotates and twists the wire is solved.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A wire stranding machine for power cable processing includes a base and support frames fixed on both sides of the base. A rotating rod is rotatably mounted between the support frames via bearings. A first wire guide disc is fixedly mounted on the outer side of the rotating rod, and there are three sets of the first wire guide discs. A second wire guide disc is rotatably mounted inside the support frame on the other side. The first and second wire guide discs have wire guide holes evenly distributed axially inside, and a wire guide roller is rotatably mounted inside the wire guide holes.

[0010] Preferably, a servo motor is fixedly installed on one side of the top front end of the base, and a gear is fixedly installed on the output end of the servo motor. Tooth blocks that mesh with the gear are uniformly fixedly installed on the outer ring of the first guide wire disc on one side.

[0011] Preferably, the support frame on the other side has an arc groove inside, and rotating balls are evenly distributed and rotated on the outer side of the second guide wire disk, and the rotating balls are slidably installed inside the arc groove.

[0012] Preferably, support wheels are fixedly installed at the front and rear ends of the top of the base, and arc-shaped guide rails are fixedly installed on the outer sides of the two outer sets of the first guide wire discs, with the support wheels sliding inside the arc-shaped guide rails.

[0013] Preferably, a protective wire mesh is movably installed on the top of the base, and casters are fixedly installed on both sides of the bottom front and rear ends of the protective wire mesh, and handles are fixedly installed on both sides of the front and rear ends of the protective wire mesh.

[0014] Preferably, limit rods are movably installed at the front and rear ends of both sides of the base, and limit rings are fixedly installed at the front and rear ends of both sides of the protective wire mesh, with the ends of the limit rods that are far apart from each other extending into the interior of the limit rings.

[0015] Compared with the prior art, this utility model provides a stranding machine for power cable processing, which has the following beneficial effects: When the device performs cable stranding operation, the cable raw material is passed through the guide hole, so that the cable raw material contacts the guide roller when passing through the guide hole. When the cable raw material passes through the guide hole, the guide roller rotates to reduce the friction between the cable raw material and the cable raw material, so that the cable stranding operation is smoother. This avoids the situation where the surface of the cable raw material is easily worn by the guide roller when the guide roller rotates during stranding due to the large friction when the cable raw material passes through the guide roller, which reduces the conductivity of the cable.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a stranding machine for power cable processing.

[0024] Please see Figures 1-5 A wire stranding machine for power cable processing includes a base 1 and support frames 101 fixed on both sides of the base 1. A rotating rod 102 is rotatably mounted between the support frames 101 via bearings. A first wire guide disc 103 is fixedly mounted on the outer side of the rotating rod 102, and there are three sets of the first wire guide discs 103. A second wire guide disc 104 is rotatably mounted inside the other support frame 101. The first wire guide disc 103 and the second wire guide disc 104 are axially distributed and evenly provided with wire guide holes 105. A wire guide roller 106 is rotatably mounted inside the wire guide holes 105.

[0025] With the above-described structural configuration, the cable stranding machine first passes the cable stranding material through the guide holes 105 inside the first guide disc 103 and the second guide disc 104, thereby bringing the cable material into contact with the guide roller 106. When the device performs stranding operations, the first guide disc 103 and the second guide disc 104 rotate. At this time, the cable material is transported and stranded. The rotation of the guide roller 106 reduces the friction between the cable material and the first guide disc 103 and the second guide disc 104, thus avoiding the problem that the surface of the cable material is easily worn by the guide disc during the rotation of the guide disc due to the large friction when the cable material passes through the guide disc, which reduces the conductivity of the cable.

[0026] Furthermore, a servo motor 107 is fixedly installed on one side of the top front end of the base 1, and a gear 108 is fixedly installed on the output end of the servo motor 107. Tooth blocks 109 that mesh with the gear 108 are evenly fixedly installed on the outer ring of the first guide wire disc 103 on one side. The rotation of the output end of the servo motor 107 drives the gear 108 to rotate. Since the gear 108 and the tooth blocks 109 mesh with each other, the tooth blocks 109 drive the first guide wire disc 103. Since the second guide wire disc 104 is fixedly connected to the outside of the rotating rod 102, the second guide wire disc 104 also rotates with the rotating rod 102, thus realizing the cable stranding operation.

[0027] Furthermore, an arcuate groove 110 is formed inside the support frame 101 on the other side. Rotating balls 111 are evenly and rotatably mounted on the outer side of the second guide wire disc 104 in an axially distributed manner, and the rotating balls 111 are slidably mounted inside the arcuate groove 110. When the second guide wire disc 104 rotates inside the support frame 101, the rotating balls 111 rotate inside the arcuate groove 110, thereby reducing the friction generated when the second guide wire disc 104 rotates inside the support frame 101, making the second guide wire disc 104 rotate more smoothly and improving the service life of the device.

[0028] Furthermore, support wheels 112 are fixedly installed at the front and rear ends of the top of the base 1, and arc-shaped guide rails 113 are fixedly installed on the outer sides of the two outer sets of first guide wire discs 103, with the support wheels 112 sliding inside the arc-shaped guide rails 113. When the first guide wire discs 103 rotate, the support wheels 112 rotate inside the arc-shaped guide rails 113, and simultaneously support the bottom of the arc-shaped guide rails 113, making the first guide wire discs 103 more stable when rotating and winding the wire.

[0029] Furthermore, a protective wire mesh 2 is movably installed on the top of the base 1. Universal wheels 201 are fixedly installed on both sides of the bottom front and rear ends of the protective wire mesh 2, and handles 202 are fixedly installed on both sides of the front and rear ends of the protective wire mesh 2. The operator holds the handles 202 and uses the universal wheels 201 to push the protective wire mesh 2 to the top of the base 1 for protection, preventing external interference from interrupting the cable stranding operation.

[0030] Furthermore, limiting rods 3 are movably installed at the front and rear ends of both sides of the base 1, and limiting rings 301 are fixedly installed at the front and rear ends of both sides of the protective wire mesh 2, with the ends of the limiting rods 3 that are far apart extending into the interior of the limiting rings 301. When the protective wire mesh 2 moves to the top of the base 1, the limiting rods 3 are moved so that the ends of the limiting rods 3 that are far apart slide into the interior of the limiting rings 301, thereby limiting and fixing the protective wire mesh 2. This prevents the protective wire mesh 2 from shifting during the wire twisting operation, thus avoiding the cable raw material being exposed to the outside environment and improving the protective effect of the device.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
