Description

Technical Field

[0001] This invention relates to a stranding device, and more particularly to a stranding device for cable production used in the field of cable manufacturing. Background Technology

[0002] Stranding equipment is a key piece of equipment in cable production used to orderly strand multiple single conductors into a conductor bundle according to a certain pitch and stranding direction. Its main function is to improve the mechanical strength, flexibility, and conductivity stability of the cable, while reducing electromagnetic interference and energy loss. Depending on the structural form, stranding equipment can be divided into various types such as frame stranding machines, tube stranding machines, and cage stranding machines, which are suitable for the production of cables of different specifications and types.

[0003] Chinese patent CN119541955B discloses a cable stranding machine and its stranding method. During stranding, multiple coils of cable are set on a conductor frame, and the conductor frame drives the multiple coils of cable to rotate to complete the stranding of the cable. There are usually multiple coils of cable. In order to ensure continuous production, the multiple coils of cable set on the conductor frame are relatively heavy, which causes most of the energy consumption of the conductor frame to be used to drive the cable to rotate, resulting in energy waste. Therefore, further improvement is needed. Summary of the Invention

[0004] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that the multiple coils of cables set on the conductor frame are relatively heavy, which causes most of the energy consumption of the conductor frame to be used to drive the cables to rotate, resulting in energy waste.

[0005] To address the aforementioned problems, this invention provides a stranding device for cable production, comprising a housing, a left support sleeve and a right support sleeve fixedly connected to the middle of the housing, a winding tube rotatably connected to one end of the left support sleeve, and a unwinding tube rotatably connected to the inner wall of the right support sleeve, one end of the unwinding tube being located inside the winding tube. A left toothed ring and a right toothed ring are fixedly connected to the inner walls of both ends of the winding tube, respectively. A rotary motor is fixedly connected to the inner wall of the left support sleeve, and a drive gear is fixedly connected to one end of the rotary motor, meshing with the left toothed ring. Multiple vertical rods are fixedly connected to the end of the unwinding tube away from the winding tube, and a rocker arm is fixedly connected to one end of each vertical rod. A bundle gatherer is fixedly connected inside the housing, located on one side of the unwinding tube. Multiple outer material trays are fixedly connected inside the housing, evenly distributed around the winding tube, with strands wound on the outer material trays. One end of each strand is spirally wound around the winding tube. A raw material tray and a finished product tray are fixedly connected to both ends of the housing, with core wire wound on the raw material tray.

[0006] As a further improvement of this application, an internal gear ring is fixedly connected to one end of the unwinding tube located inside the winding tube, and multiple support rods are fixedly connected to one end of the right support sleeve. An intermediate gear is fixedly connected to one end of the support rod, and the intermediate gear meshes with the right gear ring and the internal gear ring.

[0007] As a further improvement of this application, a plurality of evenly distributed pushers are fixedly connected to the inner wall of the housing near the tube. Each pusher includes two top blocks fixedly connected to the inner wall of the housing, and a helical rod is rotatably connected between the two top blocks. A synchronous motor is fixedly connected to the side wall of one of the top blocks, and the output end of the synchronous motor is fixedly connected to one end of the helical rod.

[0008] As a further improvement of this application, the outer wall of the screw rod is in contact with the coil tube, and the strands wound in a spiral shape on the coil tube are set as a helical line, and the pitch of the screw rod matches the pitch of the helical line.

[0009] As another improvement of this application, a ring and an outer pulley are fixedly connected to both ends of the rocker arm, and both the ring and the outer pulley are connected to the wire drive.

[0010] As a further improvement to this application, a lubrication frame is fixedly connected to the inner wall of the housing near the outer material tray, and an inner pulley is fixedly connected to one end of the lubrication frame. The inner pulley is connected to the wire drive.

[0011] As a further improvement to this application, the inner wall at the top of the lubrication frame is rotatably connected to two rotating wheels, and an oil-absorbing layer is rotatably connected between the two rotating wheels, with the bottom end of the oil-absorbing layer in contact with the strand.

[0012] As another improvement of this application, an oil nozzle is fixedly connected to the middle of the top of the lubrication frame, and the bottom end of the oil nozzle is located on the upper side of the oil absorption layer.

[0013] In summary, this invention can first transfer the strands from multiple outer material reels to the winding tube, and then complete the twisting of the strands and core wires by rotating the unwinding tube. This twisting method does not require rotating multiple reels of strands for processing, which greatly reduces the power consumption during twisting and improves the overall energy-saving effect of the equipment.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-7 This diagram illustrates a stranding device for cable production, comprising a housing 1. A left support sleeve 2 and a right support sleeve 4 are fixedly connected to the middle of the housing 1. A winding tube 3 is rotatably connected to one end of the left support sleeve 2. A unwinding tube 5 is rotatably connected to the inner wall of the right support sleeve 4, with one end of the unwinding tube 5 located inside the winding tube 3. A left toothed ring 6 and a right toothed ring 7 are fixedly connected to the inner walls of both ends of the winding tube 3, respectively. A rotary motor 11 is fixedly connected to the inner wall of the left support sleeve 2. A drive gear 12 is fixedly connected to one end of the rotary motor 11, meshing with the left toothed ring 6. The unwinding tube 5 is located away from the winding tube 4. Multiple vertical rods 15 are fixedly connected to one end of the coil tube 3, and a rocker arm 16 is fixedly connected to one end of the vertical rods 15. A bundle gatherer 17 is fixedly connected inside the housing 1. The bundle gatherer 17 is located on one side of the unloading tube 5. Multiple outer material trays 13 are fixedly connected inside the housing 1. The multiple outer material trays 13 are evenly distributed around the coil tube 3. A strand of wire 14 is wound on the outer material tray 13. One end of the strand of wire 14 is spirally wound on the coil tube 3. A raw material tray 18 and a finished product tray 19 are fixedly connected to both ends of the housing 1, respectively. A core wire 20 is wound on the raw material tray 18.

[0027] Specifically, during operation, the rotary motor 11 drives the winding tube 3 to rotate forward via the drive gear 12 and the left gear ring 6. During the forward rotation of the winding tube 3, the strand 14 is wound around the winding tube 3 in a spiral shape. At the same time as the winding tube 3 rotates forward, the unwinding tube 5 rotates in the opposite direction. During the reverse rotation of the unwinding tube 5, the rocker arm 16 rotates in the opposite direction. When the rocker arm 16 rotates in the opposite direction, it can unwind the strand 14 wound on the winding tube 3. One end of the strand 14 is connected to the core wire 20. At the same time as the rocker arm 16 rotates in the opposite direction, it can twist the strand 14 and the core wire 20 together under the action of the bundler 17. After twisting, the core wire 20 is processed and wound onto the finished product reel 19.

[0028] With the above setup, the strands 14 on multiple outer material trays 13 can be transferred to the winding tube 3 first, and then the strands 14 and core wires 20 can be twisted together by the rotation of the unwinding tube 5. This twisting method does not require rotating multiple coils of strands 14 for processing, which greatly reduces the power consumption during twisting and improves the overall energy-saving effect of the equipment.

[0029] The end of the unloading tube 5 located inside the winding tube 3 is fixedly connected to an internal gear ring 8. The end of the right support sleeve 4 is fixedly connected to multiple support rods 9. The end of the support rod 9 is fixedly connected to an intermediate gear 10. The intermediate gear 10 meshes with the right gear ring 7 and the internal gear ring 8.

[0030] When the coil tube 3 is rotating forward, it can drive the intermediate gear 10 to rotate forward through the right gear ring 7. When the intermediate gear 10 is rotating forward, it can drive the unwinding tube 5 to rotate in reverse through the internal gear ring 8. With the above settings, the unwinding tube 5 can be driven to rotate in reverse while the coil tube 3 is rotating forward.

[0031] The two ends of the rocker arm 16 are respectively fixedly connected to a ring 1601 and an outer pulley 1602, and both the ring 1601 and the outer pulley 1602 are connected to the strand 14 for transmission.

[0032] The above settings can guide the strand 14 that passes through the rocker arm 16.

[0033] Second implementation method:

[0034] Figures 1-8 This invention discloses a stranding device for cable production. Unlike the first embodiment, a plurality of evenly distributed pushers are fixedly connected to the inner wall of the housing 1 near the winding tube 3. Each pusher includes two top blocks 21 fixedly connected to the inner wall of the housing 1. A helical rod 2101 is rotatably connected between the two top blocks 21. A synchronous motor 2102 is fixedly connected to the side wall of one of the top blocks 21. The output end of the synchronous motor 2102 is fixedly connected to one end of the helical rod 2101. The outer wall of the helical rod 2101 is in contact with the winding tube 3. The strands 14 wound in a spiral shape on the winding tube 3 are configured as helical lines 22. The pitch of the helical rod 2101 matches the pitch of the helical line 22.

[0035] With the above settings, if the strands 14 need to be continuously wound onto the winding tube 3 and continuously unwound during the rotation of the winding tube 3, the winding tube 3 or the spiral 22 needs to move. In this invention, the synchronous motor 2102 is started to drive the spiral rod 2101 to rotate. Since the pitch of the spiral rod 2101 matches the pitch of the spiral 22, the spiral rod 2101 can push the spiral 22 to slide to the right during the rotation, so that the strands 14 are continuously wound onto the winding tube 3 and continuously unwound, enabling continuous operation.

[0036] A lubrication frame 23 is fixedly connected to the inner wall of the housing 1 near the outer material tray 13. An inner pulley 2301 is fixedly connected to one end of the lubrication frame 23. The inner pulley 2301 is connected to the strand 14 for transmission. Through the above arrangement, the inner pulley 2301 can guide the strand 14. Two rotating wheels 2302 are rotatably connected to the inner wall of the top of the lubrication frame 23. An oil-absorbing layer 2303 is rotatably connected between the two rotating wheels 2302. The bottom end of the oil-absorbing layer 2303 is in contact with the strand 14. An oil nozzle 2304 is fixedly connected to the middle of the top of the lubrication frame 23. The bottom end of the oil nozzle 2304 is located on the upper side of the oil-absorbing layer 2303.

[0037] With the above settings, the oil nozzle 2304 can spray lubricating oil onto the oil-absorbing layer 2303, and the rotating wheel 2302 can apply lubricating oil to the surface of the strand 14 when it drives the oil-absorbing layer 2303 to rotate, so that the spiral 22 can slide better on the coil tube 3.

[0038] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
