Description

Technical Field

[0001] This utility model belongs to the field of stranding machine technology, specifically relating to a wire and cable stranding machine. Background Technology

[0002] A stranding machine is a mechanical device that can be widely used to strand various soft and hard conductors. In the production of wires and cables, a stranding machine is used to twist multiple single conductors into a single strand to make a cable. A wire and cable stranding machine consists of three parts: a stranding device, a traction device, and a take-up device.

[0003] When using existing wire and cable stranding machines, it is necessary to place the material reel of a single conductor onto the stranding device. Due to the large weight of the material reel, additional hoisting equipment is required to lift and transport it. The additional hoisting equipment not only increases the equipment purchase cost but also increases the space occupied by the stranding machine. At the same time, when hoisting the material reel, it is necessary to lift the material reel to a high place and place it onto the stranding device from above. During the hoisting process, the material reel is at a high position, posing a safety hazard of falling and hitting the operator.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a wire and cable stranding machine.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] like Figure 1 As shown, a wire and cable stranding machine according to one embodiment of the present invention includes a stranding device, a traction device 5 and a take-up device 6. The stranding device has the functions of unwinding and stranding. The material reel 7 is placed on the stranding device for unwinding. The stranding device strands two single conductors together to form a cable. The traction device pulls the cable out at a uniform speed. The take-up device winds the stranded cable into a cable roll.

[0034] like Figure 2 As shown, the stranding device includes a base 1 and a reel support 2. The reel support 2 is mounted on the base 1, and the base 1 provides support for the reel support 2. The reel support 2 is used to place the material reel 7, and the material reel 7 completes the wire feeding on the reel support 2.

[0035] like Figure 3 , Figure 4 and Figure 6 As shown, a pair of slide rails 201 are welded to the top end face of the reel support 2. A lifting device 3 is slidably connected to the slide rails 201. The lifting device 3 is used to lift the material reel 7. When loading, the lifting device 3 is used to lift the material reel 7 to a certain height, and then the material reel 7 is placed on the reel support 2.

[0036] The lifting device 3 includes a support component, a lifting component, and a gripping component. The support component is slidably connected to the slide rail 201. The lifting component is rotatably connected to the support component. The gripping component is welded to the lifting component. The support component provides support for the lifting component and the gripping component. The gripping component is used to grip the material reel 7. The lifting component lifts the gripping component together with the material reel 7 to the required height.

[0037] like Figure 5 As shown, a support ring 203 is welded to one end face of the reel support 2. The support ring 203 has an internal thread, and a threaded rod 206 is threadedly connected to the support ring 203. A bearing 205 is welded to one end face of the threaded rod 206. The bearing 205 includes an inner ring and an outer ring. The inner ring is welded to the threaded rod 206, and a support plate 204 is welded to the outer ring. The support plate 204 is used to support the material reel 7 to complete the wire feeding operation. A first rotating wheel 207 is welded to one end face of the threaded rod 206. Rotating the first rotating wheel 207 drives the threaded rod 206 to rotate. When the threaded rod 206 rotates on the support ring 203, it achieves the extension and retraction of the threaded rod 206, which in turn drives the support plate 204 to move. This allows for the clamping and releasing of the material reel 7. Furthermore, the extension and retraction of the threaded rod 206 can be used to fix material reels 7 of different widths, thus enabling the twisting device to feed and twist material reels 7 of various widths.

[0038] like Figure 6 As shown, the support assembly includes a first sliding base 301, a second sliding base 302, and a pair of support rods 304. The first sliding base 301 and the second sliding base 302 are slidably connected to a pair of slide rails 201. The first sliding base 301 and the second sliding base 302 slide on the slide rails 201, which can move the lifting device 3 to the position corresponding to the support plate 204.

[0039] A rotating shaft 303 is welded to one end face of the support rod 304. A pair of support rods 304 are rotatably connected to the first sliding base 301 and the second sliding base 302 respectively via the rotating shaft 303. When lifting is required, the support rod 304 is rotated to the vertical direction to raise the lifting assembly, facilitating the lifting of the material reel 7. When the material reel 7 is installed in place and is being wound, the support rod 304 is rotated to the horizontal position so that the support rod 304 abuts against the slide rail 201, ensuring that the height of the support rod 304 does not affect the winding operation.

[0040] A first pin hole 314 is provided on one side end face of the first sliding base 301, and a second pin hole 315 matching the first pin hole 314 is provided on one side end face of the support rod 304. A second limiting pin 316 is inserted into the hole wall of the first pin hole 314. When the support rod 304 is rotated to the vertical direction, the second limiting pin 316 passes through the second pin hole 315, thereby keeping the support rod 304 in a direction perpendicular to the slide rail 201.

[0041] A limiting block 312 is welded to one end face of the first sliding base 301. The limiting block 312 abuts against the support rod 304, restricting the rotation of the support rod 304 and holding the support rod 304 against the other side, thereby making the support rod 304 more stable in the vertical direction.

[0042] A first limiting hole 202 is provided on one end face of the reel support 2. A fourth pin hole 318 matching the first limiting hole 202 is provided on the first sliding base 301. A first limiting pin 313 is slidably connected in the limiting block 312. The first limiting pin 313 is inserted into the side wall of the first limiting hole 202. At this time, the first limiting pin 313 can prevent the first sliding base 301 from sliding. When the first sliding base 301 needs to slide on the slide rail 201, the first limiting pin 313 is lifted so that the first limiting pin 313 slides out from the hole wall of the first limiting hole 202, and the first sliding base 301 can slide.

[0043] The lifting assembly includes a connecting rod 305, a take-up reel 306, and a wire rope 307. The connecting rod 305 is rotatably connected to the support rod 304, the take-up reel 306 is fixedly mounted on the connecting rod 305, and the wire rope 307 is wound around the take-up reel 306. A second rotating wheel 311 is welded to one end face of the connecting rod 305. Rotating the second rotating wheel 311 easily drives the connecting rod 305 to rotate, at which time the take-up reel 306 rotates synchronously, thereby causing the wire rope 307 to wind around the take-up reel 306, achieving the lifting of the gripping assembly.

[0044] The gripping assembly includes a lifting rod 308 and a pair of clamping arms 309. The lifting rod 308 is welded to a wire rope 307, which drives the lifting rod 308 upward. The pair of clamping arms 309 are slidably connected to the opposite end faces of the lifting rod 308, and a support block 310 is welded to one end face of each clamping arm 309. Multiple pairs of lifting holes 701 are provided on the opposite end faces of the material reel 7. The support block 310 is engaged within the lifting holes 701. The pair of clamping arms 309 grips the material reel 7, thereby gripping it. As the wire rope 307 pulls the lifting rod 308, the material reel 7 is lifted. Furthermore, because the clamping arms 309 are slidably connected to the lifting rod 308, it can grip material reels 7 of different widths.

[0045] A third pin hole 317 is provided on one end face of the support rod 304. The second limiting pin 316 includes a cylindrical rod and a handle. The size of the third pin hole 317 matches the handle of the second limiting pin 316, and the handle of the second limiting pin 316 can be locked into the side wall of the third pin hole 317. After the material reel 7 is installed in place, the second limiting pin 316 is pulled out, and the support rod 304 is rotated to a horizontal position without affecting the winding operation of the winding device. The handle of the second limiting pin 316 is then inserted into the third pin hole 317. The cylindrical rod of the second limiting pin 316 locks the second rotating wheel 311, thereby preventing the second rotating wheel 311 from rotating arbitrarily, thus fixing the gripping component in a specific position and not affecting the winding operation.

[0046] like Figure 5 and Figure 7 As shown, a sliding groove 101 is provided on one side of the base 1. A pallet assembly 4 is slidably connected in the groove wall of the sliding groove 101. The pallet assembly 4 includes a sliding pallet 401. A limiting groove 402 is provided on one side of the sliding pallet 401. The bottom wall of the limiting groove 402 is an arc-shaped surface that is high on both sides and low in the middle. When loading, first pull out the sliding pallet 401 and roll the material reel 7 onto the sliding pallet 401. Because the bottom wall of the limiting groove 402 is high on both sides and low in the middle, the material reel 7 will roll to the middle of the bottom surface under the action of gravity, thereby preventing the material reel 7 from rolling. Then push the sliding pallet 401 under the reel support 2. At this time, the gripping component can be used to grab the material reel 7 and then lift it to the position of the support plate 204.

[0047] Furthermore, a number of rotating rollers 102 are rotatably connected inside the side wall of the slide groove 101. The rotating rollers 102 rotate inside the side wall of the slide groove 101. When the sliding plate 401 is slidable, the bottom surface of the sliding plate 401 slides against the rotating rollers 102, thereby making it easier to slide the sliding plate 401.

[0048] Furthermore, multiple casters 404 are welded to the bottom end face of the sliding pallet 401. When the sliding pallet 401 slides out, the casters 404 provide support for the sliding pallet 401. When the material reel 7 rolls onto the sliding pallet 401, the casters 404 can prevent the part of the sliding pallet 401 that slides out of the slide groove 101 from tilting, thereby making the sliding of the sliding pallet 401 smoother.

[0049] Furthermore, a limiting plate 403 is welded to the bottom end face of the sliding tray 401. When the sliding tray 401 slides out, the limiting plate 403 abuts against one side end face of the base 1. At this time, the limiting plate 403 can prevent the sliding tray 401 from slipping out of the slide groove 101.

[0050] When using, such as Figure 1As shown, pull out the sliding tray 401 so that the material reel 7 can be rolled directly onto the sliding tray 401. The material reel 7 is locked in the limiting groove 402. Then slide the sliding tray 401 back below the reel bracket 2. Slide the first sliding base 301 to the position that matches the support plate 204. Insert the first limiting pin 313 into the wall of the first limiting hole 202. Rotate the support rod 304 to the vertical position and insert the second limiting pin 316 into the second pin hole. Within 315, the support rod 304 is fixed in a vertical position. The second rotating wheel 311 is rotated, lowering the clamping arm 309. The position of the clamping arm 309 is adjusted so that the support block 310 is engaged in the lifting hole 701. The pair of clamping arms 309 clamp the wire rope 307. At this time, rotating the second rotating wheel 311 drives the take-up reel 306 to rotate, thus winding the wire rope 307 onto the take-up reel 306. The wire rope 307 pulls the lifting rod 308 upward, driving the material reel 7 upward. When the material... After the material reel 7 rises to the designated position, the first rotating wheel 207 is rotated, and the threaded rod 206 retracts, causing the support plate 204 to abut against the material reel 7. At this time, the support plate 204 provides support for the material reel 7, and the sliding clamp arm 309 can be detached from the material reel 7. After the material reel 7 is installed in place, the first limiting pin 313 is pulled out from the first limiting hole 202, the first sliding base 301 and the second sliding base 302 are slid to a certain position, and the second limiting pin is pulled out. By rotating the support rod 304 through the positioning pin 316, the support rod 304 is rotated to a position parallel to the slide rail 201. The second rotating wheel 311 is rotated to raise the lifting rod 308 to a position that does not affect the winding operation. The handle of the second limiting pin 316 is inserted into the third pin hole 317, so that the cylindrical rod of the second limiting pin 316 locks the second rotating wheel 311, thereby restricting the rotation of the second rotating wheel 311, and thus fixing the lifting rod 308 and the clamp arm 309 in a position that does not affect the winding.
