Technical Field
[0001] This utility model relates to the field of wire and cable equipment technology, specifically to an auxiliary wire laying device for a cable-making machine. Background Technology
[0002] Cable forming machines are core equipment in wire and cable production. They are mainly used to combine multiple insulated cores (or conductors) into round or sector-shaped cables through a stranding process, adding filler ropes (such as PP filler ropes) during stranding to maintain cable structural stability. In wire and cable production, PP stranded filler rope (polypropylene stranded filler rope) is a commonly used auxiliary material, mainly used to improve the structural stability, safety, and performance of cables. Filler ropes are typically supplied via a wire feeding device, which feeds the coiled wire to the cable forming machine for stranding with multiple insulated cores (or conductors).
[0003] For example, Chinese Patent 202321010478.3 discloses a fan-shaped filler rope feeding device for high-voltage cable production, including a mounting frame. A main shaft is connected to the left inner wall of the mounting frame via a bearing. A motor is located on the right inner wall of the mounting frame, with its output end penetrating the right inner wall and connected to one end of the main shaft. A drive motor is located at the bottom of a sliding plate, with its output end penetrating the bottom of the sliding plate and connected to one end of a rotating shaft. A gear that meshes with teeth is sleeved on the outer wall of the rotating shaft. A limiting plate is located at the top of the sliding plate. This device employs a traditional horizontally positioned roller-type feeding frame.
[0004] Regarding the aforementioned existing technologies, traditional horizontally placed roller-type wire feeding frames have limited capacity for filling wires, requiring frequent replacements or machine shutdowns for replacement, resulting in low production efficiency and high labor intensity. Utility Model Content
[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an auxiliary wire feeding device for a cable forming machine. This device solves the technical problem that the traditional horizontal roller-type wire feeding frame in the prior art has a limited capacity for filling wire, requires constant replacement or machine shutdown for replacement, and has low production efficiency.
[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0007] This utility model provides an auxiliary cable laying device for a cable-making machine, comprising:
[0008] Base;
[0009] A support frame, mounted on the base, has multiple planes for placing coiled wire; and
[0010] A wire feeding assembly includes a frame and a wire feeding component. The frame is mounted on the base, and the wire feeding component is installed on the frame and suspended above the upright. The wire feeding component has a threading part for the wire to pass through.
[0011] In some embodiments, the frame includes a lifting mechanism and a base frame. The lifting mechanism is mounted on the base, and the movable end of the lifting mechanism is connected to the base frame to drive the base frame to rise and fall. A plurality of the wire feeding components are linearly arranged on the base frame.
[0012] In some embodiments, the wire feeding component includes a rotating bracket connected to the frame and having a rotatable rotating end, and the wire threading portion is connected to the rotating end.
[0013] In some embodiments, the threading portion includes a cylindrical body connected to the rotating end of the rotating bracket, for the wire to pass through the inner side of the cylindrical body.
[0014] In some embodiments, the support frame includes a lifting assembly, a first shelf and a second shelf, the first shelf being fixedly connected to the lifting assembly, and the movable end of the lifting assembly being connected to the second shelf, thereby driving the second shelf to rise and fall above the first shelf.
[0015] In some embodiments, the support frame includes a lifting assembly and a plurality of shelves, the lifting assembly being disposed between adjacent shelves.
[0016] In some embodiments, a first fence is connected to the lifting assembly, and a second fence is slidably connected to the first fence.
[0017] In some embodiments, both the first and second layers are provided with an open sleeve for accommodating the tail end of the wire.
[0018] In some embodiments, the second layer plate is provided with an open guide sleeve for guiding the wire direction via a bracket.
[0019] In some embodiments, both the open sleeve and the open guide sleeve are U-shaped.
[0020] Compared with existing technologies, the cable-laying machine auxiliary wire-laying device provided by this utility model uses a stand to vertically place the rolled PP stranded filler rope wire, and pulls the end of the wire to the upper threading part to pass through, forming a high-altitude suspended auxiliary wire-laying. Then, it is pulled to the cable-laying machine's wire-separating plate to meet the cable core. The high-altitude suspended auxiliary wire-laying provides vertical stacking space, allowing for the stacking of higher wires along the direction perpendicular to the ground. Furthermore, during the wire-laying process, the end of the wire is always close to the ground. When a roll of PP stranded filler rope is about to be used up, the end of the previous roll of wire can be connected to the end of the next roll of wire in advance, and the joint can be sealed with transparent tape in advance. This allows for the replacement of filler rope without stopping the machine, achieving uninterrupted production without speed reduction. The operation is simple and applicable.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0029] To address the limitations of traditional horizontal roller-type wire feeding frames in terms of capacity for filler wire, requiring frequent or machine-stopping replacements and resulting in low production efficiency, this invention provides an auxiliary wire feeding device for cable forming machines. This device allows for the vertical placement of coiled PP stranded filler rope wire on a support frame. The end of the wire is then pulled to the upper threading section for threading, forming a high-altitude suspended auxiliary wire feeding. The wire is then pulled to the cable forming machine's splitter plate to join the cable core. This high-altitude suspended auxiliary wire feeding provides vertical stacking space, allowing for the stacking of higher wires perpendicular to the ground. Furthermore, during the feeding process, the end of the wire remains close to the ground. When a coil of PP stranded filler rope is nearly used up, the end of the previous coil can be pre-connected to the end of the next coil by sealing the joint with transparent tape. This allows for filler rope replacement without machine downtime, ensuring uninterrupted production without speed reduction. The device is simple to operate and applicable.
[0030] It should be noted that the cable-making machine auxiliary pay-off device described in this utility model is used for, but is not limited to, the auxiliary pay-off of PP stranded filler rope to the cable-making machine. For ease of explanation, this utility model will only use the application of the cable-making machine auxiliary pay-off device to the auxiliary pay-off of PP stranded filler rope to the cable-making machine as an example. The principle of the cable-making machine auxiliary pay-off device applied to other types of equipment is essentially the same as the principle applied to the auxiliary pay-off of PP stranded filler rope to the cable-making machine, and will not be described in detail here.
[0031] Please see Figure 1 , Figure 1 This is a three-dimensional view of an auxiliary cable laying device for a cable forming machine according to an embodiment of the present invention. The auxiliary cable laying device includes a base 1, a support frame 2, and a cable laying assembly 3. The support frame 2 is installed on the base 1 and has a plane for vertically placing coiled wire. The PP stranded filler rope coiled wire is placed vertically on the plane for cable laying. The cable laying assembly 3 includes a frame 31 and a cable laying component 32. The frame 31 is mounted on the base 1, and the cable laying component 32 is installed on the frame 31 and suspended above the support frame 2. The cable laying component 32 has a threading part 321 for the wire to pass through, forming a high-altitude suspended structure. The end of the PP stranded filler rope coiled wire is pulled upward and passes through the threading part 321, forming a traction to guide it to the high altitude. Then it is pulled to the cable forming machine's branch plate to meet the cable core and fill the gap between the cable cores, and is cabled and twisted together with the cable cores.
[0032] In this embodiment, each roll of long-length PP stranded filler rope is placed on a wooden pallet, and a forklift transports the PP stranded filler rope to the plane where the coiled wire is placed on the upright 2. The high-altitude suspended auxiliary wire laying provides stacking space in the vertical space, allowing for the stacking of higher wires along the direction perpendicular to the ground. During the wire laying process, the tail end of the wire is always close to the ground. When a roll of PP stranded filler rope is about to be used up, the tail end of the previous roll of wire can be connected to the end of the next roll of wire in advance, and the joint can be sealed with transparent tape in advance, allowing for the replacement of filler rope without stopping the machine.
[0033] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3To facilitate the pulling of the filler rope to the suspended threading part 321, the frame 31 includes a lifting mechanism 311 and a base frame 312. The lifting mechanism 311 is installed on the base 1, and the movable end of the lifting mechanism 311 is connected to the base frame 312, driving the base frame 312 to rise and fall. After the base frame 312 is lowered, the height of the threading part 321 can be reduced, making it easier for workers to perform threading operations. Several threading components 32 are linearly arranged on the base frame 312. The number of threading components 32 is determined according to the number of PP stranded filler ropes to be threaded, and the number of PP stranded filler ropes is determined by the number of filler ropes to be twisted.
[0034] In this embodiment, the number of cable release components 32 is at least three, corresponding to three strands of PP parallel-strand filler rope, which are filled into the three gaps between the cable cores one by one for cable stranding.
[0035] Understandably, the lifting mechanism 311 can employ a screw-guide pair driven by a bevel gear assembly. The bevel gear assembly consists of a pair of meshing bevel gears, one of which is connected to the screw, and the other is connected to a rotary handle. Rotation drives the screw to rotate, and a slider that slides relative to the guide rail is connected to the screw. The slider is connected to the base frame 312 for lifting. Alternatively, the lifting mechanism 311 can also employ existing equipment with lifting functions such as pneumatic push rods or hydraulic push rods; this is not a limiting factor.
[0036] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 In order to adapt the orientation of the cable-laying machine to different orientations for the cable-laying guidance, the cable-laying component 32 includes a rotating bracket 322, which is connected to the frame 31 and has a rotatable rotating end 322a. The cable threading part 321 is connected to the rotating end 322a. During the filling rope traction process, the cable threading part 321 will be pulled, guiding the rotating end 322a to rotate, so that it is adaptively adjusted to the orientation with relatively low friction, thereby improving the smoothness of the traction direction.
[0037] In this embodiment, the rotating bracket 322 is connected to the base frame 312 through the frame 31 by a rotating shaft and upper and lower limiting components, which restricts the rotation of the upper and lower positions. The limiting components can be nuts, forming a sustainable structure.
[0038] Furthermore, the threading part 321 includes a cylindrical body 321a, which is connected to the rotating end 322a of the rotating bracket 322, allowing the wire to pass through the inner side of the cylindrical body 321a. Both ends of the cylindrical body 321a are chamfered towards their inner walls to avoid excessive friction with the wire.
[0039] In feasible embodiments, the threading portion 321 may also be a semi-circular ring, and the semi-circular ring may also be covered by a flip-up cover plate to provide a structure that makes it easier to thread the wire.
[0040] Understandably, the threading section 321 only needs to be able to allow the wire to pass through and provide effective traction guidance and suspension, and is not limited to a single one.
[0041] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 In order to stack materials in at least two layers and continuously replace materials and connect cables, the support frame 2 includes a lifting assembly 21 and multiple shelves. In this embodiment, the multiple shelves include a first shelf 22 and a second shelf 23. The first shelf 22 is fixedly connected to the lifting assembly 21. The movable end of the lifting assembly 21 is connected to the second shelf 23, driving the second shelf 23 to rise and fall above the first shelf 22. The second shelf 23 has a first position state of descending to near the first shelf 22, and a second position height of raising the second shelf 23 to a position height between the first shelf 22 and the second shelf 23 where a roll of filler rope can be placed. When placing the cable, first lower the second layer plate 23, place one roll of cable on the second layer plate 23, then raise the second layer plate 23 and place another roll of cable on the first layer plate 22. Connect the end of the upper cable to the end of the lower cable, thus forming two rolls of cable stacked vertically and joined end-to-end, increasing the stock of consumables per use. Furthermore, after the upper cable is used up, the second roll of cable can be automatically used because the two rolls are joined end-to-end. At this time, when the lower cable is almost used up, the second layer plate 23 can be lowered to place new cable, and the end of the new cable can be connected to the end of the lower cable to form a continuous supply of cable.
[0042] Understandably, two-layer stacking can provide uninterrupted and alternating replenishment of cables. If space permits, three-layer stacking or more can also be used, but neither is as practical as two-layer stacking in terms of safety and operability.
[0043] Furthermore, in order to provide basic lifting and lowering functions, the lifting assembly 21 includes a connecting frame 211 and a hydraulic push rod 212. The hydraulic push rod 212 is mounted on the base 1, and the telescopic end of the hydraulic push rod 212 is connected to the connecting frame 211. The connecting frame 211 is fixedly connected to the second layer plate 23. By extending and retracting the hydraulic push rod 212, the connecting frame 211 and the second layer plate 23 are driven to rise and fall.
[0044] Understandably, there are at least two hydraulic push rods 212. The connecting frame 211 can be connected to all the second-layer plates 23. Since multiple sets of wires are consumed synchronously, the extension and retraction of the hydraulic push rods 212 can drive the connecting frame 211 and all the second-layer plates 23 to lift and lower simultaneously, and place the wires synchronously.
[0045] For further details, please refer to Figure 1 In order to place the tail ends of the wires in each layer on the outside of the layer plate, the outer sides of the first layer plate 22 and the second layer plate 23 are provided with open sleeves 24 to accommodate the tail ends of the wires. By pulling out the tail ends of the wires and inserting them into the open sleeves 24, it is convenient to connect the head and tail of the two rolls of wires later.
[0046] For further details, please refer to Figure 1 In order to guide the wire above the second layer plate 23 to the suspension point, i.e. to the wire threading part 321, the second layer plate 23 is provided with an open guide sleeve 25 for guiding the wire direction by means of a bracket. Its height is at least higher than the height of the coiled wire. Together with the open sleeve 24 on the second layer plate 23, it can guide the wire direction.
[0047] Understandably, when the upper wire and lower wire blocks are used up, if the upward pulling route of the wire blocks the space for the upper wire to be placed, the wire needs to be manually pushed aside before feeding. Therefore, by setting the open guide sleeve 25 on the side of the second layer plate 23, together with the open sleeve 24 on the second layer plate 23, a feeding route can be formed to guide the lower wire to extend upward from the side, avoiding obstruction of the front feeding space of the second layer plate 23.
[0048] Furthermore, both the open sleeve 24 and the open guide sleeve 25 are U-shaped and have an opening, which facilitates the insertion and extraction of wires.
[0049] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 In order to form a barrier around the wires and prevent them from falling over and causing safety hazards, a first fence 213 is connected to the lifting assembly 21. A second fence 214 is slidably connected to the first fence 213. When the second fence 214 slides and overlaps with the first fence 213, it provides at least space for loading and unloading the wires. When the second fence 214 slides and overlaps with the first fence 213 to form a barrier around the shelf, it provides protection for at least half of the area and prevents the wires from falling over.
[0050] In this embodiment, the first fence 213 is divided into two parts, located on both sides of the second layer plate 23 respectively, and the first fence 213 is slidably connected to the first fence 213 on the opposite side of the open sleeve 24.
[0051] Understandably, depending on the actual situation, the enclosure area can be increased to provide more comprehensive protection, which will not be elaborated here.
[0052] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail as follows: In initial use, a roll of filler rope is placed vertically on the second layer plate 23, and the wire feeding component 32 is lowered simultaneously by the lifting mechanism 311. The end of the rope is passed through the inner side of the cylinder 321a of the wire threading part 321, forming a high-altitude suspended auxiliary wire feeding. Then, the second layer plate 23 is lifted by the lifting component 21, and the second roll of filler rope is placed vertically on the first layer plate 22, and the end of the second roll is connected to the end of the first roll. When the second roll is about to be used up, the second layer plate 23 is lowered, a third roll is placed on it, and the end of the third roll is connected to the end of the second roll. This process is repeated to continuously feed and feed the rope, allowing for the replacement of filler rope without stopping the machine, achieving uninterrupted production without speed reduction. The operation is simple and applicable.
[0053] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
