Description

Technical Field

[0001] This invention relates to the field of stranding machine technology, and more specifically to a stranding machine that produces uniformly stranded wire. Background Technology

[0002] A stranding machine is a type of mechanical equipment that can be widely used to strand various soft / hard conductor wires (copper wire, enameled wire, tinned wire, copper-clad steel, copper-clad aluminum, etc.) and electronic wires (such as power cords, headphone wires, telephone wires, PVC wires, network cables, etc.), turning multiple single conductors into one strand to meet the process requirements of the wire.

[0003] The wire frame of existing stranding machines is usually disc-shaped, such as the patent with publication number CN101359525. However, when a large number of wire spools need to be stranded, multiple wire spools need to be installed on the disc-shaped wire frame at the same time, which requires the wire frame to be made larger, resulting in a larger footprint for the stranding machine. Summary of the Invention

[0004] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is: when a large number of wire spools are needed for stranding, multiple wire spools need to be installed on the disc-shaped wire frame at the same time, which requires the wire frame to be made larger, resulting in a larger footprint of the stranding machine.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a uniform stranding machine, comprising: a rotating wire feeding device, including a wire frame, guide wheels, and a rotating mechanism; the wire frame includes a machine frame and multiple wire reel frames; multiple wire reel frames are mounted on the machine frame, and the multiple wire reel frames are arranged in a linear array on the machine frame; the guide wheels correspond one-to-one with the wire reel frames, and the guide wheels are mounted on the machine frame at different heights; the rotating mechanism drives the machine frame to rotate; a converging device gathers the wires to a point; and a take-up device pulls the stranded wire and rewinds the stranded wire.

[0006] In this invention, the wire spools are installed on a wire spool frame, and then the wires on the spools are wound around the guide rollers and pulled to a converging device. The converging device merges multiple wires, and then pulls the multiple wires to a take-up device. The take-up device pulls the stranded wire and winds it up. At the same time, a rotating mechanism drives the wire frame to rotate, so that the multiple wires are twisted into one strand at the converging device, thereby achieving the purpose of stranding. By arranging the wire spools in a linear array and cooperating with the guide rollers of different heights, the wire frame can effectively reduce the space occupied.

[0007] Preferably, the device further includes a guiding device, which comprises a guide post and multiple guiding mechanisms. The guide post is fixedly connected to the frame. The multiple guiding mechanisms are arranged in a circular array with the axis of the guide post as the center, and each guiding mechanism corresponds to a wire reel holder. Each guiding mechanism includes a first limiting wheel, a second limiting wheel, and a third limiting wheel. The first limiting wheel, the second limiting wheel, and the third limiting wheel are arranged in a straight line, with the first and second limiting wheels parallel to each other. The third limiting wheel is located on the side closer to the merging device, and is perpendicular to the second limiting wheel. The guiding mechanism guides the wire and simultaneously limits its movement in multiple directions.

[0008] Preferably, the guide post and the frame are fixedly connected by a connecting mechanism; the connecting mechanism includes a tapered frame, a first connecting plate, and a second connecting plate; one end of the tapered frame is equipped with the first connecting plate, which is fixedly connected to the frame, and the other end of the tapered frame is equipped with the second connecting plate, which is fixedly connected to the guide post; and the first and second connecting plates are respectively provided with multiple guide holes, each corresponding to a wire reel, and the outer diameter of the first connecting plate is larger than the outer diameter of the second connecting plate. This allows multiple wires to be pre-converged, resulting in more uniform twisting during the twisting process.

[0009] Preferably, the rotating mechanism includes two rotating frames, which are located on opposite sides of the frame along its length. The rotating frames are rotatably connected to the frame. The two rotating frames suspend the frame, facilitating its rotation.

[0010] Preferably, the merging device includes a fixed sleeve, extrusion members, and a transmission mechanism; the fixed sleeve is coaxially arranged with the rotating wire feeding device; a plurality of extrusion members are arranged in a circular array with the axis of the fixed sleeve as the center; one end of each extrusion member is planar, with the planar end of the extrusion member close to the axial direction, and the other end of the extrusion member is slidably connected to the fixed sleeve; the transmission mechanism adjusts the sliding distance of the plurality of extrusion members. By adjusting the sliding distance of the extrusion members through the transmission mechanism, it can be adapted to stranded wires of different thicknesses.

[0011] Preferably, the extrusion component includes a sliding plate, an extrusion frame, and a rotating shaft; multiple parallel rotating shafts are rotatably mounted on both sides of the extrusion frame, and the rotating shafts on both sides are staggered; the sliding plate is fixedly connected to the extrusion frame, and the sliding plate is perpendicular to the rotating shafts, and the sliding plate is slidably connected to the fixed sleeve. The rotatable arrangement of the rotating shaft can reduce the friction between the stranded wire and the rotating shaft, allowing the stranded wire to pass through the polygonal sleeve more conveniently.

[0012] Preferably, the transmission mechanism includes an actuator, a transmission belt, and a motor; each actuator corresponds to an extrusion piece, and each actuator includes an elliptical wheel, a connecting rod, and a transmission wheel; the connecting rod is rotatably mounted in a fixed sleeve, and the elliptical wheel and transmission wheel are mounted on the connecting rod; the elliptical wheel has an elliptical groove, and a sliding block is fixedly mounted on the extrusion piece, the sliding block being disposed within the elliptical groove and slidably connected to the elliptical groove; the transmission belt is sleeved on multiple transmission wheels; the motor drives one of the connecting rods to rotate. When the motor operates, it drives the connecting rod to rotate, and simultaneously, through the cooperation of the transmission belt and transmission wheel, it drives the other connecting rods to rotate, thereby driving the elliptical wheel to rotate, causing the sliding block on the extrusion piece to slide within the elliptical groove, thus driving the extrusion piece to slide.

[0013] Preferably, the wire reel holder is detachably connected to the frame, facilitating the replacement of the wire reel.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] 1. In this invention, the wire spool is installed on the wire spool frame, and then the wire on the spool is wound around the guide wheel and pulled to the converging device. The converging device merges multiple wires, and then pulls the multiple wires to the take-up device. The take-up device pulls the stranded wire and winds it up. At the same time, the rotating mechanism drives the wire frame to rotate, so that the multiple wires are twisted into one strand at the converging device, thereby achieving the purpose of stranding. By arranging the wire spools in a linear array and cooperating with the guide wheels of different heights, the wire frame can effectively reduce the space occupied.

[0016] 2. In this invention, the wires on multiple wire reels are passed through a fixed sleeve and installed on a take-up device. Then, the extrusion piece is driven by a transmission mechanism to move toward multiple wires to be stranded, so that the flat end of the extrusion piece is in contact with the wires, which makes it easier to gather the wires to a point. At the same time, by adjusting the sliding distance of the extrusion piece by the transmission mechanism, it can be adapted to strands of different thicknesses and can make the strands more uniform.

[0027] See Figure 1The present invention provides an embodiment of a uniform stranding machine, comprising: a rotating wire feeding device, including a wire frame 1, guide rollers 2, and a rotating mechanism; the wire frame 1 includes a machine frame 11 and multiple wire reel frames 12; multiple wire reel frames 12 are mounted on the machine frame 11, and the multiple wire reel frames 12 are arranged in a linear array on the machine frame 11; further, the wire reel frames 12 are detachably connected to the machine frame 11; facilitating the replacement of wire reels; the guide rollers 2 correspond one-to-one with the wire reel frames 12, and the guide rollers 2 are mounted on the machine frame 11 at staggered heights; the rotating mechanism drives the machine frame 11 to rotate; further, the rotating mechanism includes two rotating frames 6, which are located on both sides of the length direction of the machine frame 11, and the rotating frames 6 are rotatably connected to the machine frame 11; the two rotating frames 6 suspend the machine frame 11, facilitating the rotation of the machine frame 11; a converging device to converge the wires to a point; and a take-up device to pull the stranded wire and take it up. In practice, the wire spools are installed on the wire spool frame 12, and then the wires on the spools are wound around the guide rollers 2 and pulled to the converging device. The converging device merges multiple wires, and then pulls the multiple wires to the take-up device. The take-up device pulls the stranded wire and winds it up. At the same time, the rotating mechanism drives the wire frame 1 to rotate, so that the multiple wires are twisted into one strand at the converging device, thereby achieving the purpose of stranding. By arranging the wire spools in a linear array and cooperating with the guide rollers 2 at different heights, the wire frame 1 can effectively reduce the space occupied.

[0028] See Figures 1-2 In other embodiments, a guiding device 4 is also included. The guiding device 4 includes a guide post 41 and multiple guiding mechanisms. The guide post 41 is fixedly connected to the frame 11. The multiple guiding mechanisms are arranged in a circular array with the axis of the guide post 41 as the center, and each guiding mechanism corresponds to a wire reel holder 12. The guiding mechanism includes a first limiting wheel 42, a second limiting wheel 43, and a third limiting wheel 44. The first limiting wheel 42, the second limiting wheel 43, and the third limiting wheel 44 are arranged in a straight line in sequence. The first limiting wheel 42 and the second limiting wheel 43 are parallel to each other, and the third limiting wheel 44 is located on the side closer to the converging device, and the third limiting wheel 44 is perpendicular to the second limiting wheel 43. In specific implementation, the wire on the wire reel is wound in an S-shape around the first limiting wheel 42 and the second limiting wheel 43, then limited and guided by the third limiting wheel 44, and then enters the converging device for converging. Through the setting of the guiding mechanism, the wire can be guided and limited in multiple directions.

[0029] See Figures 1-2In other embodiments, the guide post 41 is fixedly connected to the frame 11 via a connecting mechanism 5. The connecting mechanism 5 includes a tapered frame 51, a first connecting plate 52, and a second connecting plate 53. The first connecting plate 52 is mounted on one end of the tapered frame 51 and is fixedly connected to the frame 11. The second connecting plate 53 is mounted on the other end of the tapered frame 51 and is fixedly connected to the guide post 41. The first connecting plate 52 and the second connecting plate 53 are respectively provided with multiple guide holes 3, each corresponding to a wire reel frame 12. The outer diameter of the first connecting plate 52 is larger than the outer diameter of the second connecting plate 53. In specific implementation, the wires on the reel are sequentially passed through the guide holes 3 on the first connecting plate 52 and the second connecting plate 53, and then guided and limited by the guiding device 4. This allows multiple wires to be pre-converged, resulting in more uniform twisting during the twisting process.

[0030] See Figures 1-3 In other embodiments, the converging device includes a fixed sleeve 7, extrusion members 8, and a transmission mechanism 9; the fixed sleeve 7 is coaxially arranged with the rotating wire feeding device; multiple extrusion members 8 are arranged in a circular array with the axis of the fixed sleeve 7 as the center; one end of the extrusion member 8 is planar, and the planar end of the extrusion member 8 is close to the axial direction, while the other end of the extrusion member 8 is slidably connected to the fixed sleeve 7; the transmission mechanism 9 adjusts the sliding distance of the multiple extrusion members 8. In specific implementation, the wires on multiple wire reel holders 12 are passed through the fixed sleeve 7 and installed on the take-up device, and then the transmission mechanism 9 drives the extrusion members 8 to move toward the multiple wires to be stranded, so that the planar end of the extrusion member 8 is in contact with the wires, which facilitates the convergence of the wires to a point. At the same time, by adjusting the sliding distance of the extrusion members 8 through the transmission mechanism 9, it can be adapted to stranded wires of different thicknesses.

[0031] See Figures 1-4 In other embodiments, the extrusion member 8 includes a sliding plate 81, an extrusion frame 82, and a rotating shaft 83. Multiple parallel rotating shafts 83 are rotatably mounted on both sides of the extrusion frame 82, and the rotating shafts 83 on both sides are staggered. The sliding plate 81 is fixedly connected to the extrusion frame 82, and the sliding plate 81 is perpendicular to the rotating shafts 83. The sliding plate 81 is slidably connected to the fixed sleeve 7. In specific implementation, the staggered rotating shafts 83 on both sides of the extrusion frame 82 form a plane. The array arrangement of multiple extrusion members 8 allows the rotating shafts 83 of adjacent extrusion members 8 to also be staggered and able to insert into the gaps between them. This results in a larger contact area between the plane and the wire, forming a polygonal sleeve that effectively prevents wire leakage. Simultaneously, the rotatable arrangement of the rotating shafts 83 reduces the friction between the stranded wire and the rotating shafts 83, allowing the stranded wire to pass through the polygonal sleeve more easily.

[0032] See Figures 1-5In another embodiment, the transmission mechanism 9 includes an actuator, a transmission belt 91, and a motor. Each actuator corresponds to one of the extrusion parts 8. The actuator includes an elliptical wheel 93, a connecting rod 94, and a transmission wheel 95. The connecting rod 94 is rotatably mounted within the fixed sleeve 7, and the elliptical wheel 93 and transmission wheel 95 are mounted on the connecting rod 94. The elliptical wheel 93 has an elliptical groove 96. A sliding block 84 is fixedly mounted on the extrusion part 8, and the sliding block 84 is located within the elliptical groove 96 and slidably connected to it. The transmission belt 91 is sleeved on multiple transmission wheels 95. The motor drives one of the connecting rods 94 to rotate. In specific implementation, the motor drives the connecting rod 94 to rotate, and simultaneously, through the cooperation of the transmission belt 91 and the transmission wheel 95, it drives the other connecting rods 94 to rotate, thereby driving the elliptical wheel 93 to rotate. This causes the sliding block 84 on the extrusion part 8 to slide within the elliptical groove 96, thus driving the extrusion part 8 to slide.
