[0010] The lubrication and cooling mechanism comprises: a lubrication component, which is arranged on the first rotating rod; a cooling component, which is arranged on the workbench; and an erasing component, which is arranged on the workbench.

[0011] The lubrication assembly includes: a second connecting shaft, which is arranged in the first rotating rod, and a plurality of through grooves are opened in the first rotating rod; a through block, and a plurality of the through blocks are installed on the second connecting shaft; a rotating ring, which is installed on the through block; a fixed sleeve, which is installed on the outside of the rotating ring; a conical sponge, which is installed on the second connecting shaft, and the second connecting shaft, the through block and the rotating ring are provided with flow grooves; and a collection box, which is installed on the fixed sleeve.

[0012] The cooling assembly includes: a support frame, which is installed on the workbench; a cooling box, which is installed on the support frame; a return box, which is arranged on the ground; a first pipeline, which is arranged between the cooling box and the return box; and a circulating pump, which is arranged on the first pipeline.

[0013] A linear drive is installed on the reflux box, a lifting plate is installed on the output end of the linear drive, a bending pipe and a collecting box are installed on the lifting plate, and the collecting box is connected to the collecting box through a second pipeline.

[0014] The erasing assembly includes: a second elastic connecting member, which is arranged on one side of the cooling box; a U-shaped plate, which is arranged at the free end of the second elastic connecting member; a driving wheel, which is rotatably arranged in the U-shaped plate, and the driving wheel is in contact with the wire; a second rotating rod, which is mounted on the driving wheel; an inclined plate, which is mounted on the U-shaped plate; a second rotating shaft, which is rotatably arranged on the inclined plate; an erasing wheel, which is mounted on the second rotating shaft; and a bevel gear, which is mounted on the second rotating rod and the second rotating shaft, and the two bevel gears are meshed.

[0015] The guide assembly includes: a first connecting shaft, which is mounted on the rotating disk; a first disc, which is mounted on the first connecting shaft; a first guide wheel, which is mounted on the first disc; a second disc, which is mounted on the first connecting shaft; and a second guide wheel, which is mounted on the second disc.

[0016] The beneficial effects of the present invention are: (1) In the process of rotating the rotating disk of the present invention, the first gear and the gear ring are meshed with each other, driving the rotating shaft to rotate, thereby driving the wire reel to rotate along the axis of the rotating shaft. When the wire reel unwinds the branch wire, the branch wire is driven to rotate, and a self-spinning torsional force f is applied to the branch wire. When the branch wire is twisted into a conductor, the self-spinning torsional force f on the branch wire enhances the winding force between the multiple branch wires inside, thereby enhancing the overall strength of the conductor.

[0017] (2) The present invention drives the first rotating rod to rotate by a rotating driving member, thereby driving the circular sleeve to rotate. Since the abutment block abuts against the inner wall of the placement groove, the friction between the abutment block and the inner wall of the placement groove drives the rotating disk to rotate, thereby applying a twisting force F to the branch wire, so that multiple branch wires are twisted into a conductor. When the applied twisting force F is too large, a certain resistance will be formed to the rotation of the rotating disk. When the resistance is greater than the friction between the abutment block and the inner wall of the placement groove, the abutment block will slide along the inner wall of the placement groove (idling), thereby preventing the twisting force F from continuing to increase and possibly causing the wire to break, thereby protecting the wire.

[0018] (3) The present invention uses a flat knife to insert into the square groove and rotate the first rotating shaft. Due to the meshing of the worm and the worm wheel, the connecting rod is driven to rotate, the rotating disk is driven to rotate, the sliding rod slides in the arc groove, and the moving block is driven to move outward to squeeze the first elastic connecting member, thereby increasing the friction between the resistance block and the placement groove, thereby 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.

[0019] (4) The present invention drives the conical block to move within the rotating shaft by rotating the screw, and the bottom of the elastic strip slides on the conical surface of the conical block, driving the elastic strip to extend into or leave the slot, thereby adjusting the extension length of the elastic strip into the slot. The greater the extension length, the greater the spin torsional force f applied to the branch line, thereby achieving the adjustment of the spin torsional force f.

[0020] (5) The present invention drives the driving wheel to contact the wire under the elastic force of the second elastic connecting member, and the winding mechanism on one side of the workbench winds up the wire after twisting, drives the driving wheel to rotate, drives the second rotating rod to rotate, drives the second rotating shaft to rotate through the bevel gear, drives the erasing wheel to rotate to erase the surface of the wire, and makes the lubricating oil on the surface of the wire fall into the coolant in the cooling box.

[0021] (6) The present invention uses a circulating pump to pump the coolant in the cooling box into the reflux box. At this time, the lubricating oil will float on the top layer of the coolant. The linear drive member drives the lifting plate to move downward. The lubricating oil on the top layer of the coolant will enter the collecting box along the curved pipe, and then the lubricating oil will be separated from the coolant. The lubricating oil in the collecting box is then transferred to the collecting box through the curved pipe for reuse. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] Embodiment 1: Figure 1-Figure 20 As shown, the present embodiment provides a stranding machine for cable production, including a work frame 100, a rotating driving member 101 is installed on the work frame 100, a first rotating rod 102 is installed at the output end of the rotating driving member 101, a rotating disk 103 is provided on the outer side of the first rotating rod 102, a plurality of rotating shafts 104 are provided on the rotating disk 103, a U-shaped frame 105 is installed on the rotating shaft 104, a wire roll 106 is arranged in the U-shaped frame 105, a workbench 107 is provided on one side of the work frame 100, a collection frame 108 is installed on the workbench 107, a through hole 1081 is opened in the collection frame 108, a winding mechanism is provided on one side of the workbench 107, a guide assembly 11, an adjustment mechanism 2 and a lubrication and cooling mechanism 3 are provided on the work frame 100, it should be noted that: the wire roll 106 unwinds the branch line 801, and the wire roll 106 has some resistance to the rotation and unwinding relative to the U-shaped frame 105, and the wire roll 106 does not unwind without external force; 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.

[0028] 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.

[0029] like Fig.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; like Figure 1-Figure 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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. 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; 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.

[0038] Embodiment 2: Figure 1-Figure 20 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: like Figure 1-Figure 20 As shown, the lubrication and cooling mechanism 3 in this embodiment includes: a lubrication component 31, which is arranged on the first rotating rod 102; a cooling component 32, which is arranged on the workbench 107; and an erasing component 33, which is arranged on the workbench 107.

[0040] In this embodiment, the lubricating oil in the collecting box 316 flows along the flow groove 310 into the second connecting shaft 311 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.

[0041] The cooling assembly 32 includes: a support frame 321, which is installed on the workbench 107; a cooling box 322, which is installed on the support frame 321; a reflux box 323, which is arranged on the ground; a first pipe 324, which is arranged between the cooling box 322 and the reflux box 323; and a circulating pump 325, which is arranged on the first pipe 324.

[0045] In this embodiment, under the elastic force of the second elastic connecting member 331, the driving wheel 333 is driven to contact the wire 802, and the winding mechanism on one side of the workbench 107 winds up the wire 802 after twisting, driving the driving wheel 333 to rotate, driving the second rotating rod 334 to rotate, driving the second rotating shaft 336 to rotate through the bevel gear 338, and 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.

[0046] In this embodiment, the circulation pump 325 draws the coolant from 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 drive member 326 drives the lifting plate 327 to move downward. The lubricating oil on the top layer of the coolant will enter the collecting box 329 along the curved pipe 328, and then the lubricating oil will be separated from the coolant. The lubricating oil in the collecting box 329 is then transferred to the collecting box 316 through the curved pipe 328 for reuse.

[0047] Working steps Step 1, wire twisting process: 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 wire 802. The winding mechanism on one side of the workbench 107 winds up the wire 802 after twisting. 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. 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; 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; 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; 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; Step 7, cooling process: the wire 802 passes through the cooling box 322, and the coolant in the cooling box 322 cools the wire 802; Step 8, erasing process: under the elastic force of the second elastic connecting member 331, the driving wheel 333 is driven to contact the wire 802, and the winding mechanism on one side of the workbench 107 winds up the wire 802 after twisting, and the driving wheel 333 is driven to rotate, driving the second rotating rod 334 to rotate, driving the second rotating shaft 336 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; Step nine, purification process: the circulation 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 drive 326 drives the lifting plate 327 to move downward. The lubricating oil on the top layer of the coolant will enter the collecting box 329 along the curved pipe 328, and then the lubricating oil will be separated from the coolant. The lubricating oil in the collecting box 329 is then transferred to the collecting box 316 through the curved pipe 328 for reuse.
