Description

Technical Field

[0001] The present invention relates to the technical field of stranding, and in particular to a stranding machine for cable production. Background Art

[0002] A stranding machine is an important device in cable production, which is used to strand multiple thin wires into the core wire of a cable conductor, helping to improve the flexibility, durability and electrical conductivity of the cable, and also being able to reduce signal loss and increase the durability and flexibility of the cable.

[0003] Chinese Patent Application No. 2023113293353 discloses an adjustable stranding machine for cable production, including a bottom plate, a support seat is installed on the bottom plate, a first motor is installed above the support seat, a gear is fixedly connected to the output shaft of the first motor, a toothed ring is meshed with the side of the gear, a turntable is fixedly connected to the front end of the toothed ring, the turntable is rotatably installed inside a first bracket, a wire pay-off assembly is installed on the turntable, a hydraulic rod is fixedly installed on the bottom plate, a steel belt is fixedly connected above the hydraulic rod, and a connecting ring is connected above the steel belt, and the connecting ring is rotatably installed outside a second bracket.

[0004] As Figure 21 shown, the above-mentioned stranding machine can strand multiple branch wires 801 into a conductor 802. However, during the stranding process of the branch wires 801, it is not convenient to apply a self-rotating torsional force to the branch wires 801. As a result, when the conductor 802 is stranded, the winding force between the internal branch wires 801 is small, making the overall strength of the conductor 802 low. Therefore, we propose a stranding machine for cable production. Summary of the Invention

[0005] The purpose of the present invention is to provide a stranding machine for cable production in view of the deficiencies of the prior art. During the rotation of the rotating disk, due to the meshing of the first gear and the toothed ring, the rotating shaft is driven to rotate, driving the wire reel to rotate along the axis of the rotating shaft. When the wire reel pays off the branch wire, it drives the branch wire to rotate self, applying a self-rotating torsional force f to the branch wire. When the conductor is stranded, the self-rotating torsional force f on the branch wire enhances the winding force between multiple internal branch wires, thereby enhancing the overall strength of the conductor.

[0012] The lubricating and cooling mechanism includes: a lubricating component, which is arranged on the first rotating rod; a cooling component, which is arranged on the workbench; an erasing component, which is arranged on the workbench.

[0013] The lubricating assembly includes: a second connecting shaft disposed within the first rotating rod, and a plurality of through grooves are formed in the first rotating rod; a plurality of penetrating blocks mounted on the second connecting shaft; a rotating ring mounted on the penetrating blocks; a fixed sleeve mounted on the outer side of the rotating ring; a conical sponge mounted on the second connecting shaft, and flow grooves are formed in the second connecting shaft, the penetrating blocks, and the rotating ring; an aggregate box mounted on the fixed sleeve.

[0014] The cooling assembly includes: a support frame mounted on the workbench; a cooling box mounted on the support frame; a return box disposed on the ground; a first pipeline disposed between the cooling box and the return box; a circulation pump disposed on the first pipeline.

[0015] A linear driving member is mounted on the return box, a lifting plate is mounted on the output end of the linear driving member, a bent pipe and a collecting box are mounted on the lifting plate, and the collecting box is communicated with the aggregate box through a second pipeline.

[0016] The erasing assembly includes: a second elastic connecting member disposed on one side of the cooling box; a U-shaped plate disposed at the free end of the second elastic connecting member; a driving wheel rotatably disposed within the U-shaped plate, and the driving wheel abuts against a wire; a second rotating rod mounted on the driving wheel; an inclined plate mounted on the U-shaped plate; a second rotating shaft rotatably disposed on the inclined plate; an erasing wheel mounted on the second rotating shaft; bevel gears mounted on the second rotating rod and the second rotating shaft, and the two bevel gears are engaged with each other.

[0017] The guiding assembly includes: a first connecting shaft mounted on the rotating disc; a first disc mounted on the first connecting shaft; a plurality of first guiding wheels mounted on the first disc; a second disc mounted on the first connecting shaft; a plurality of second guiding wheels mounted on the second disc.

[0018] The beneficial effects of the present invention are as follows:

[0019] (1) During the rotation of the rotating disk in the present invention, since the first gear and the toothed ring are engaged, the rotating shaft is driven to rotate, driving the wire reel to rotate along the axis of the rotating shaft. When the wire reel pays out the branch wire, the branch wire is driven to rotate self, applying a self-rotating torsional force f to the branch wire. When twisting into a wire, the self-rotating torsional force f on the branch wire enhances the winding force between multiple internal branch wires, thereby enhancing the overall strength of the wire.

[0020] (2) In the present invention, the first rotating rod is driven to rotate by the rotating driving member, driving the circular sleeve to rotate. Since the abutting block abuts against the inner wall of the placement groove, the frictional force between the abutting block and the inner wall of the placement groove drives the rotating disk to rotate, thereby applying a wire twisting force F to the branch wire, twisting multiple branch wires into a wire. When the applied twisting force F is too large, it will form a certain resistance to the rotation of the rotating disk. When this resistance is greater than the frictional force between the abutting block and the inner wall of the placement groove, the abutting block will slide along the inner wall of the placement groove (idle rotation occurs), avoiding the wire from being twisted and broken due to the continuous increase of the twisting force F, and protecting the wire.

[0021] (3) In the present invention, by inserting a flat-blade screwdriver into the square groove and rotating the first rotating shaft, since the worm is engaged with the worm gear, the connecting rod is driven to rotate, driving the rotating disk to rotate. The sliding rod slides in the arc-shaped groove, driving the moving block to move outwards to squeeze the first elastic connecting member, increasing the frictional force between the abutting block and the placement groove, and thus increasing the magnitude of the twisting force F. Similarly, the magnitude of the twisting force F can be reduced. It can be seen that the twisting force F can be adjusted to an appropriate range.

[0022] (4) In the present invention, by rotating the screw rod, the tapered block is driven to move in the rotating shaft. The bottom of the elastic strip slides on the tapered surface of the tapered block, driving the elastic strip to extend into or out of the card slot, adjusting the extending length of the elastic strip inserted into the card slot. The greater the extending length, the greater the self-rotating torsional force f applied to the branch wire, and thus the adjustment of the self-rotating torsional force f can be realized.

[0023] (5) In the present invention, under the elastic force of the second elastic connecting member, the driving wheel is driven to contact the wire. The winding mechanism on one side of the workbench winds the twisted wire, driving the driving wheel to rotate, driving the second rotating rod to rotate, and driving the second rotating shaft to rotate through the bevel gear, driving the erasing wheel to rotate to erase the surface of the wire, so that the lubricating oil on the surface of the wire falls into the coolant in the cooling tank.

[0024] (6) In the present invention, the coolant in the cooling tank is pumped into the reflux tank by the circulation pump. At this time, the lubricating oil will float on the top layer of the coolant. The linear driving member drives the lifting plate to move downwards, and the lubricating oil on the upper layer of the coolant will enter the collection box along the curved pipe, thereby separating the lubricating oil from the coolant, and then transmitting the lubricating oil in the collection box to the aggregate box through the curved pipe for reuse.

[0050] Embodiment 1: As Figures 1 - 20 shown, this embodiment provides a stranding machine for cable production, including a working frame 100. A rotary driving member 101 is installed on the working frame 100. A first rotating rod 102 is installed at the output end of the rotary driving member 101. A rotating disk 103 is arranged outside the first rotating rod 102. A plurality of rotating shafts 104 are arranged on the rotating disk 103. A U-shaped frame 105 is installed on the rotating shaft 104. A wire coil 106 is arranged inside the U-shaped frame 105. A workbench 107 is arranged on one side of the working frame 100. An assembling frame 108 is installed on the workbench 107. A through hole 1081 is opened inside the assembling frame 108. A winding mechanism is arranged on one side of the workbench 107. A guiding assembly 11, an adjusting mechanism 2 and a lubricating and cooling mechanism 3 are arranged on the working frame 100. It should be noted that: the wire coil 106 pays out the branch wire 801, and there is some resistance when the wire coil 106 rotates and pays out relative to the U-shaped frame 105. Without external force, the wire coil 106 does not pay out.

[0051] The guide assembly 11 includes: a first connecting shaft 111, the first connecting shaft 111 is installed on the rotating disk 103; a first disc 112, the first disc 112 is installed on the first connecting shaft 111; a first guide wheel 113, a plurality of first guide wheels 113 are installed on the first disc 112; a second disc 114, the second disc 114 is installed on the first connecting shaft 111; a second guide wheel 115, a plurality of second guide wheels 115 are installed on the second disc 114.

[0052] In this embodiment, the rotating drive member 101 drives the rotating disk 103 to rotate, and the wire reel 106 unwinds the branch wire 801. After the branch wire 801 is wound around the first guide wheel 113 and the second guide wheel 115, multiple branch wires 801 are twisted in the through hole 1081 of the collection frame 108 to form the conductor 802, and the winding mechanism on one side of the workbench 107 winds up the twisted conductor 802.

[0053] like Figure 21 As shown, the rotating drive member 101 drives the rotating disk 103 to rotate, which will apply a twisting force F to the branch wires 801, so that multiple branch wires 801 are twisted into wires 802. If the twisting force F applied is too large, the wires 802 are easily twisted off, so twisting protection is required when twisting the wires;

[0054] like Figures 1 - 20 As shown, the adjustment mechanism 2 includes a first adjustment component 21 and a second adjustment component 22. The first adjustment component 21 adjusts the twisting force when the conductors are twisted, and the second adjustment component 22 adjusts the spin torsional force when a single branch line is twisted.

[0055] The first adjustment component 21 includes: a round sleeve 211, which is installed on the first rotating rod 102 and has a plurality of square holes 2111 therein; a first elastic connecting member 212, which is disposed in the square holes 2111; a resistance block 213, which is disposed at the free end of the first elastic connecting member 212; a placement groove 1031 is disposed in the rotating disk 103, the round sleeve 211 is disposed in the placement groove 1031, and the resistance block 213 is in resistance to the inner side of the placement groove 1031.

[0056] In this embodiment, the rotating drive member 101 drives the first rotating rod 102 to rotate, thereby driving the circular sleeve 211 to rotate. Since the resistance block 213 is in resistance with the inner wall of the placement groove 1031, the friction between the resistance block 213 and the inner wall of the placement groove 1031 drives the rotating disk 103 to rotate, thereby applying a twisting force F to the branch line 801, so that multiple branch lines 801 are twisted into wires 802. When the applied twisting force F is too large, a certain resistance will be formed to the rotation of the rotating disk 103. When the resistance is greater than the friction between the resistance block 213 and the inner wall of the placement groove 1031, the resistance block 213 will slide along the inner wall of the placement groove 1031 (idle rotation) to prevent the twisting force F from continuing to increase and possibly causing the wire 802 to break, thereby protecting the wire 802.

[0057] It should be noted that the friction between the abutment block 213 and the inner wall of the placement slot 1031 will affect the twisting force F. For wires 802 made of different metal materials, the twisting force F required for twisting is different, so the twisting force F needs to be adjustable.

[0058] A moving block 214 is slidably provided in the square hole 2111, and a sliding rod 215 is installed on the moving block 214. A rotating disk 216 is rotatably provided in the circular sleeve 211, and a plurality of arc grooves 2161 are provided in the rotating disk 216, and the sliding rod 215 slides in the arc groove 2161; a connecting rod 217 is installed on the rotating disk 216, and a worm gear 218 is installed on the connecting rod 217; a first rotating shaft 219 is rotatably provided in the first rotating rod 102, and a worm 220 is installed at one end of the first rotating shaft 219, and the worm 220 is meshed with the worm gear 218, and a square groove 2191 is provided at the other end of the first rotating shaft 219.

[0059] In this embodiment, a flat knife is inserted into the square groove 2191 to rotate the first rotating shaft 219. Since the worm 220 is meshed with the worm wheel 218, the connecting rod 217 is driven to rotate, and the rotating disk 216 is driven to rotate. The slide bar 215 slides in the arc groove 2161, and the moving block 214 is driven to move outward to squeeze the first elastic connecting member 212, thereby increasing the friction between the resistance block 213 and the placement groove 1031, and then increasing the size of the twisting force F. Similarly, the size of the twisting force F can be reduced. It can be seen that the twisting force F can be adjusted to an appropriate range.

[0060] The second adjustment assembly 22 includes: a first gear 221, the first gear 221 is mounted on the rotating shaft 104; a fixed plate 222, the fixed plate 222 is mounted on the working frame 100, a gear ring 223, the gear ring 223 is mounted on the fixed plate 222, the first gear 221 and the gear ring 223 are meshed; a receiving groove 1051 and a plurality of slots 1052 are provided in the U-shaped frame 105; a plurality of slide grooves 1041 are provided in the rotating shaft 104; a screw 224, the screw rod 224 is threadedly connected to the rotating shaft 104; the conical block 225, the conical block 225 is rotatably arranged at one end of the screw rod 224; the elastic strip 226, the elastic strip 226 is slidably arranged in the slide groove 1041, one end of the elastic strip 226 is inserted into the card groove 1052, and the other end of the elastic strip 226 is slidably connected to the conical block 225, a plurality of T-slots 2251 are opened on the conical block 225, and a T-block 227 is installed at the bottom of the elastic strip 226.

[0061] In this embodiment, during the rotation of the rotating disk 103, due to the meshing of the first gear 221 and the gear ring 223, the rotating shaft 104 is driven to rotate, and the wire reel 106 is driven to rotate along the axis of the rotating shaft 104. When the wire reel 106 unwinds the branch wire 801, it drives the branch wire 801 to rotate, and applies a spinning torsional force f to the branch wire 801. When the branch wire 801 is twisted into a conductor 802, the spinning torsional force f on the branch wire 801 enhances the winding force between the multiple branch wires 801 inside, thereby enhancing the overall strength of the conductor 802.

[0062] It should be noted that: since the elastic strip 226 is inserted into the slot 1052, when the rotating shaft 104 rotates, the U-shaped frame 105 and the wire coil 106 will be driven to rotate. The elastic strip 226 is elastic. When the self-spinning torsional force f on the branch line 801 is too large, the elastic strip 226 will be separated from the slot 1052. At this time, the rotation of the rotating shaft 104 will not drive the U-shaped frame 105 and the wire coil 106 to rotate (idle rotation), reducing the possibility of the branch line 801 being broken due to the excessive self-spinning torsional force f applied to the branch line 801.

[0063] For branch wires 801 made of different metal materials, the spin torsion force f required when twisting the wires is different, so it is necessary to adjust the spin torsion force f;

[0064] In this embodiment, by rotating the screw 224, the conical block 225 is driven to move in the rotating shaft 104, and the bottom of the elastic strip 226 slides on the conical surface of the conical block 225, driving the elastic strip 226 to extend into or leave the slot 1052, and adjusting the insertion length of the elastic strip 226 into the slot 1052. The greater the insertion length, the greater the spin torsional force f applied to the branch line 801, thereby realizing the adjustment of the spin torsional force f. It should be noted that the bottom of the elastic strip 226 has low elasticity and is not easy to deform.

[0065] Embodiment 2: Figures 1 - 20As shown, the components that are the same as or corresponding to those in the first embodiment are denoted by the corresponding reference numerals in the first embodiment.

[0068] In this embodiment, the lubricating oil in the aggregate box 316 flows into the second connecting shaft 311 along the flow grooves 310 until it reaches the conical sponge 315 at one end of the second connecting shaft 311. The conical sponge 315 contacts the branch line 801, and then the lubricating oil is applied to the branch line 801 to lubricate the wire 802 during stranding, reducing the possibility of wire breakage.

[0069] The cooling component 32 includes: a support frame 321 mounted on the workbench 107; a cooling box 322 mounted on the support frame 321; a return box 323 disposed on the ground; a first pipe 324 disposed between the cooling box 322 and the return box 323; and a circulation pump 325 disposed on the first pipe 324.

[0073] In this embodiment, under the elastic force of the second elastic connecting member 331, the driving wheel 333 is driven into contact with the wire 802. The winding mechanism on one side of the workbench 107 winds the twisted wire 802. The driving wheel 333 is driven to rotate, driving the second rotating rod 334 to rotate. Through the bevel gears 338, the second rotating shaft 336 is driven to rotate, driving the erasing wheel 337 to rotate to erase the surface of the wire 802, causing the lubricating oil on the surface of the wire 802 to fall into the coolant in the cooling box 322.

[0074] In this embodiment, the circulating pump 325 pumps the coolant in the cooling box 322 into the return box 323. At this time, the lubricating oil will float on the uppermost layer of the coolant. The linear driving member 326 drives the lifting plate 327 to move downward. The lubricating oil on the upper layer of the coolant will enter the collecting box 329 along the curved pipe 328, thereby separating the lubricating oil from the coolant. Then, the lubricating oil in the collecting box 329 is transmitted through the curved pipe 328 to the aggregate box 316 for reuse.

[0075] Working steps

[0076] Step 1, the wire twisting process: The rotary driving member 101 drives the rotary disk 103 to rotate. The wire coil 106 unwinds the branch wires 801. After the branch wires 801 pass around the first guide wheel 113 and the second guide wheel 115, multiple branch wires 801 are twisted within the through holes 1081 of the collecting frame 108 to form the wire 802. The winding mechanism on one side of the workbench 107 winds the twisted wire 802.

[0077] Step 2, twisted wire protection process: the rotating driving member 101 drives the first rotating rod 102 to rotate, and drives the circular sleeve 211 to rotate. Since the abutment block 213 abuts against the inner wall of the placement groove 1031, the friction between the abutment block 213 and the inner wall of the placement groove 1031 drives the rotating disk 103 to rotate, thereby applying a twisting force F to the branch line 801, so that multiple branch lines 801 are twisted into conductors 802. When the applied twisting force F is too large, a certain resistance will be formed to the rotation of the rotating disk 103. When the resistance is greater than the friction between the abutment block 213 and the inner wall of the placement groove 1031, the abutment block 213 will slide along the inner wall of the placement groove 1031 (idle rotation) to prevent the twisting force F from continuing to increase and possibly causing the conductor 802 to be twisted off, thereby protecting the conductor 802.

[0078] Step 3, twisting force adjustment process: by inserting a flat knife into the square groove 2191, rotating the first rotating shaft 219, the worm 220 is meshed with the worm wheel 218, driving the connecting rod 217 to rotate, driving the rotating disk 216 to rotate, and the sliding rod 215 slides in the arc groove 2161, driving the moving block 214 to move outward to squeeze the first elastic connecting member 212, increasing the friction between the resistance block 213 and the placement groove 1031, and then increasing the twisting force F. Similarly, the twisting force F can be reduced. It can be seen that the twisting force F can be adjusted to a suitable range;

[0079] Step 4, twisting and stranding process: during the rotation of the rotating disk 103, the first gear 221 and the gear ring 223 are meshed, driving the rotating shaft 104 to rotate, driving the wire reel 106 to rotate along the axis of the rotating shaft 104, and the wire reel 106 drives the branch wire 801 to rotate when unwinding the branch wire 801, applying a spin twisting force f to the branch wire 801, and when the branch wire 801 is twisted into the conductor 802, the spin twisting force f on the branch wire 801 enhances the winding force between the multiple branch wires 801 inside, thereby enhancing the overall strength of the conductor 802;

[0080] Step 5, twisting and adjusting the stranding process: by rotating the screw 224, the conical block 225 is driven to move in the rotating shaft 104, and the bottom of the elastic strip 226 slides on the conical surface of the conical block 225, driving the elastic strip 226 to extend into or leave the slot 1052, and adjusting the extension length of the elastic strip 226 into the slot 1052. The greater the extension length, the greater the spin torsion force f applied to the branch line 801, and the spin torsion force f can be adjusted;

[0081] Step 6, lubrication process: the lubricating oil in the collecting box 316 flows into the second connecting shaft 311 along the flow groove 310 until it flows to the conical sponge 315 at one end of the second connecting shaft 311. The conical sponge 315 contacts the branch line 801, and then the lubricating oil is applied to the branch line 801 to lubricate the wire 802 when twisting the wire, thereby reducing the possibility of wire breakage;

[0082] Step Seven, Cooling Process: The wire 802 passes through the cooling box 322, and the coolant in the cooling box 322 cools the wire 802.

[0083] Step Eight, Erasing Process: Under the elastic force of the second elastic connecting piece 331, the driving wheel 333 is driven to contact the wire 802. The winding mechanism on one side of the workbench 107 winds the twisted wire 802. The driving wheel 333 rotates, driving the second rotating rod 334 to rotate. The second rotating shaft 336 is driven to rotate through the bevel gear 338, driving the erasing wheel 337 to rotate to erase the surface of the wire 802, so that the lubricating oil on the surface of the wire 802 falls into the coolant in the cooling box 322.

[0084] Step Nine, Purifying Process: The circulating pump 325 pumps the coolant in the cooling box 322 into the reflux box 323. At this time, the lubricating oil will float on the top layer of the coolant. The linear driving member 326 drives the lifting plate 327 to move downward, and the lubricating oil on the upper layer of the coolant will enter the collecting box 329 along the curved pipe 328, thereby separating the lubricating oil from the coolant. Then, the lubricating oil in the collecting box 329 is transmitted to the aggregate box 316 through the curved pipe 328 for reuse.

[0085] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
