Description

Technical Field

[0001] This utility model relates to the technical field of cable production, specifically a multi-core cable laying device for electrical cable forming equipment. Background Technology

[0002] Cage-type cable forming machines are specialized equipment used in power cable factories to strand control cables, rubber cables, steel strands, steel-cored aluminum strands, copper strands, aluminum strands, and flexible strands.

[0003] Existing 6+12 / 630 cage stranding machines can only produce multi-core cables with 19 cores or less. When the cable has more than 19 cores, it needs to be produced on other cage stranding equipment, which is inconvenient during production. Therefore, the inventors have provided a multi-core cable laying device specifically for electrical cable forming equipment to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-core cable laying device for electrical cable forming equipment, so as to achieve the effect of producing cables with more than 19 cores.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A multi-core cable laying device for electrical cable forming equipment includes a main shaft, a winch is fixedly connected to the outside of the main shaft, a tension mechanism is provided inside the winch, the tension mechanism includes connecting shafts fixedly connected to the left and right sides inside the winch respectively, a cable reel frame is rotatably connected to the outside of the connecting shaft, a set of cable reel shafts is fixedly connected to the inside of the cable reel frame, and a cable reel is fixedly installed on the outside of the cable reel shafts.

[0007] As a further improvement of this utility model: a set of guide rollers is fixedly installed on the right side of the spool frame, and the guide rollers correspond one-to-one with the spool shaft.

[0008] As a further improvement of this utility model, a stop bar is provided on the outer side of the guide roller.

[0009] As a further embodiment of this utility model: a groove is formed on the right side of the connecting shaft, and a quick-locking stop is rotatably connected inside the groove via a hinge. A right tension seat is abutted on the left side of the quick-locking stop, and a right top cone seat is fixedly connected to the left side of the right tension seat. The right tension seat and the right top cone seat are slidably connected to the connecting shaft, and the left side of the right top cone seat abuts against the wire reel frame. A left tension seat for adjusting tension is slidably connected to the left end of the outer side of the connecting shaft, and a left top cone seat is fixedly connected to the right side of the left tension seat. The right side of the left top cone seat abuts against the left surface of the wire reel frame.

[0010] As a further embodiment of this utility model: a retaining ring is fixedly connected to the left outer end of the connecting shaft, a threaded groove is formed on the outer surface of the connecting shaft, a tension adjusting nut is threadedly connected to the outer side of the threaded groove, a tension spring is abutted against the right side of the tension adjusting nut, and the right side of the tension spring is fixedly connected to the left tension seat.

[0011] As a further improvement of this utility model, a nylon friction pad is provided on the right side surface of the left top cone seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This specialized multi-core cable-laying device for electrical cabling combines the initial ends of the wire cores on the reel by winding them around the guide rollers. Then, wire cores from other reels are combined in the same way, and the ends of all the wire cores are fixed to the traction device. The winch then rotates with the main shaft, and the wire cores on the reel frame begin to be released under their own weight and the cable-laying tension. This causes multiple wire cores to move in a circular motion around a central axis, twisting them into a single cable. During this cable-forming process, the number of reels on the reel shaft can be controlled according to the number of cores in the cable being produced; a single winch can simultaneously produce cables with more than 19 cores. This achieves the effect of producing cables with more than 19 cores.

[0014] Furthermore, the multi-core wire feeding device specifically designed for electrical cable forming utilizes a tension adjusting nut. When the tension adjusting nut moves to the right along the threaded groove, the tension spring is further compressed. This compressed elastic force acts on the left tension seat and the left top cone seat, increasing the contact force between the left top cone seat and the wire reel frame, thus slowing down the rotation speed of the wire reel frame. Conversely, when the tension adjusting nut moves to the left along the threaded groove, the deformed tension spring slowly unfolds to the left, relatively increasing the rotation speed of the wire reel frame. By altering the contact force between the left top cone seat and the wire reel frame, the wire reel frame rotates under appropriate resistance, achieving smooth wire feeding.

[0020] like Figure 1-3 As shown, a multi-core cable laying device for electrical cable forming equipment includes a main rotating shaft 10. A winch 11 is fixedly connected to the outside of the main rotating shaft 10. A tension mechanism 20 is provided inside the winch 11. The tension mechanism 20 includes connecting shafts 201 fixedly connected to the left and right sides inside the winch 11 respectively. A wire reel frame 12 is rotatably connected to the outside of the connecting shaft 201. A set of wire reel shafts 13 is fixedly connected to the inside of the wire reel frame 12. A wire reel is fixedly installed on the outside of the wire reel shafts 13.

[0021] Preferably, a set of guide rollers 14 are fixedly installed on the right side of the wire reel frame 12, and the guide rollers 14 correspond one-to-one with the wire reel shafts 13. In use, the initial ends of the wire cores on the reels are wrapped around the surface of the guide rollers 14 and joined together. Then, the wire cores on the other wire reel shafts 13 are joined together in the same way, and the ends of all the wire cores are fixed to the traction device. Then, the winch 11 rotates with the main shaft 10, and the wire cores on the wire reel frame 12 begin to be released under their own weight and the wire release tension. To ensure smooth wire release and stable tension, the winch 11 continues to rotate, driving multiple wire cores to make circular motions around a central axis, so that the wire cores are twisted into a cable. During this cable forming process, the number of reels on the wire reel shafts 13 can be controlled according to the number of cores in the cable being produced. One winch 11 can simultaneously twist up to 36 cores into a cable. This allows for the production of cable products with 19 or more cores.

[0022] Preferably, a baffle (not shown in the figure) is provided on the outer side of the guide roller 14; this can prevent the wire core from jumping during the twisting process.

[0023] refer to Figure 3 , 4A groove is formed on the right side of the connecting shaft 201. A quick-lock stop 210 is rotatably connected inside the groove via a hinge. A right tension seat 202 abuts against the left side of the quick-lock stop 210. A right top cone seat 203 is fixedly connected to the left side of the right tension seat 202. The right tension seat 202 and the right top cone seat 203 are slidably connected to the connecting shaft 201. The left side of the right top cone seat 203 abuts against the coil frame 12. A left tension seat 205 for adjusting tension is slidably connected to the outer left end of the connecting shaft 201. A left top cone seat 204 is fixedly connected to the right side of the left tension seat 205. The right side of the left top cone seat 204 abuts against the left surface of the coil frame 12.

[0024] Specifically, a retaining ring 206 is fixedly connected to the left outer end of the connecting shaft 201, and a threaded groove is opened on the outer surface of the connecting shaft 201. A tension adjusting nut 207 is threadedly connected to the outer side of the threaded groove. A tension spring 208 is abutted against the right side of the tension adjusting nut 207, and the right side of the tension spring 208 is fixedly connected to the left tension seat 205.

[0025] In use, to adjust the rotational speed of the wire reel frame 12 as it rotates with the winch 11, the tension adjusting nut 207 can be rotated. When the tension adjusting nut 207 moves to the right along the threaded groove, the tension spring 208 is further compressed. The elastic force of the compressed tension spring 208 acts on the left tension seat 205 and the left top cone seat 204, thereby increasing the contact force between the left top cone seat 204 and the wire reel frame 12, thus slowing down the rotational speed of the wire reel frame 12. Conversely, when the tension adjusting nut 207 moves to the left along the threaded groove, the deformed tension spring 208 slowly unfolds to the left, pressing against the surface of the tension adjusting nut 207. The elastic force of the unfolded tension spring 208 decreases, reducing the contact force applied to the surface of the left top cone seat 204 against the wire reel frame 12, thus relatively increasing the rotational speed of the wire reel frame 12. By changing the contact force of the left top cone seat 204 against the wire reel frame 12, the wire reel frame 12 rotates under appropriate resistance, achieving smooth wire feeding.

[0026] Furthermore, a nylon friction pad is provided on the right side surface of the left top cone seat 204; during use, the nylon friction pad contacts the surface of the spool frame 12, which facilitates the adjustment of the rotation speed of the spool frame 12, thereby further increasing the smoothness of the spool unloading.

[0027] The working principle of this invention is as follows: the initial ends of the wire cores on the wire reel are gathered together around the surface of the guide roller 14, and the wire cores on other wire reel shafts 13 are gathered together in the same way. Then, the ends of all the wire cores are fixed to the traction device. The winch 11 then rotates with the main shaft 10, and the wire cores on the reel frame 12 begin to be released under their own weight and the tension of the wire feeding. To ensure smooth feeding and stable tension, the winch 11 continues to rotate, driving multiple wire cores to make circular motions around a central axis, thus twisting the wire cores into a cable. During this cable forming process, the number of reels on the wire reel shaft 13 can be controlled according to the number of cores in the cable being produced. One winch 11 can simultaneously twist up to 36 cores into a cable. This achieves the effect of producing cable products with 19 or more cores.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
