Description

Technical Field

[0001] The invention belongs to the technical field of wire twisting machines, in particular to a full-automatic frame-type wire twisting machine. Background Art

[0002] Wire twisting machine is a kind of mechanical equipment that can be widely used in twisting various soft / hard conductor wires. It twists multiple single wires into one strand to meet the process requirements of wires. Wire twisting machines can generally be divided into pair twisting machines, cage twisting machines, frame twisting machines and disc twisting machines according to the twisting method. Among them, the frame twisting machine is mainly used as a special equipment for twisting rubber cables, copper stranded wires and soft stranded wires produced by power cable factories.

[0003] A patent application with publication number CN215815386U discloses an existing fully automatic cage-type stranding machine. This patent uses a limit block and a fixed shaft as well as a limit spring and a limit gear in combination, so that when the stranding machine is working, the connecting shaft and the limit gear outside the connecting shaft are driven by a driving motor to rotate. When the limit gear rotates, it drives the limit block to deflect around the fixed shaft. When the limit block deflects, it drives the limit spring to twist. When the teeth outside the limit gear are separated from the baffle outside the limit block, the limit block is reset under the action of the elastic force of the limit spring. When the machine stops, the baffle can be clamped between the teeth outside the limit gear, and the elastic force of the limit spring prevents the limit gear from reversing, thereby effectively avoiding the occurrence of reverse wire.

[0004] In the above-mentioned prior art, the limit block and the fixed shaft as well as the limit spring and the limit gear are used in coordination, so that the stranding drum can be stopped urgently when the stranding machine stops working to avoid the occurrence of wire bending. However, it is inconvenient to clamp the remaining wires in actual application, and the remaining wires are still in the stranding process. This causes the remaining wires to still be bent and detached from the stranding holes, causing workers to waste a lot of time on sorting. Moreover, the existing stranding machine is inconvenient to adjust the wire drum height according to the cable model produced, resulting in contact friction between two adjacent single wires when producing thicker cables, causing wear and affecting the cable processing quality.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1.

[0021] 2. The fully automatic frame-type stranding machine described in the present invention strands the wire by pulling the wire with an external winding device. The wire will drive the wire drum and the mounting column to rotate. At the same time, the mounting column drives the cylinder to rotate outside the first fixed block, thereby driving the gear during the rotation of the cylinder, and rotating the abutment block to rotate during the rotation of the gear.

[0022] 3. The fully automatic frame-type stranding machine described in the present invention, during the stranding process of the wires, uses the tension spring in the inner cavity of the slide groove to pull the support rod, and the support rod pulls the wires close to each other through the wire arrangement hole, so as to avoid that the angle of the wire arrangement is too large during the stranding process of multiple wires, which in turn affects the density between the multiple wires when they are twisted into a main wire, resulting in unstable conductivity of the finished cable in the later stage.

[0023] 4. The fully automatic frame-type wire twisting machine described in the present invention cuts the wires after the wire twisting is completed, and then uses the spring in the inner cavity of the storage groove to push the slide bar, and the slide bar uses the through hole to cooperate with the twisting hole to squeeze and fix the remaining wires, thereby further preventing the remaining wires from falling over and avoiding a lot of manual time wasted in re-arranging the wires in the later stage.

[0024] 5. The fully automatic frame-type stranding machine described in the present invention rotates the transmission frame through the second rotating column, and makes the transmission frame expand by the rotating shaft transmission rod, and at the same time pushes the U-shaped telescopic frame to slide inside the fixed disk to drive the first fixed block, so that the first fixed block drives the installation column and the wire drum away from the fixed disk to adjust the position, and then the wire drum and the wire drum on the right side of the fixed disk are misaligned, thereby preventing friction between the wires and thus affecting the life of the finished cable in the later stage. It also solves the problem that the existing fully automatic frame-type stranding machine is inconvenient to install the wire drum according to the needs of the produced cable, and it is inconvenient to adjust the position between the wire drums, resulting in friction between the lead-out wires.

[0041] Specifically, when it is necessary to adjust the spacing between the two wire drums, the staff drives the transmission frame 16 to rotate by rotating the first rotating column 13 and the second rotating column 14 respectively, and makes the transmission frame 16 expand by using the rotating shaft to drive the pull rod 17, so that during the expansion process, the pull rod 17 uses the rotating shaft to push the U-shaped telescopic frame 18 to slide inside the fixed disk 6, driving the first fixed block 19, and then the first fixed block 19 drives the wire drum on the mounting column 25 away from or close to the fixed disk 6, so that the spacing between the two wire drums is adjusted, and the height difference is misaligned, so as to avoid friction between the wires when the external winding equipment pulls the external wire of the wire drum for twisting, thereby preventing the life of the finished cable from being affected in the later stage.

[0043] Specifically, personnel pull the wire outside the wire drum through the wire arrangement hole 46 and the twisting hole 36 to gather at the limit hole 9, and install and connect with the external winding device, and then, while the external winding device rotates the traction wire, start the drive motor 11 to rotate the first sprocket 3, the transmission chain 4 drives the second sprocket 5, and the second sprocket 5 rotates the connecting column 15 to drive the fixed disk 6, and then, during the rotation process, the fixed disk 6 uses the fixed column 10 to rotate the first capstan 34 and the second capstan 35, so that the first capstan 34 and the second capstan 35 drive multiple wires to twist to form a main line, thereby facilitating the twisting processing of multiple wires.

[0044] like Figure 3 and 5 As shown, the second rotating column 14 is fixedly connected to a transmission frame 16 on the outside, and the transmission frame 16 is rotatably connected to a pull rod 17 at one end away from the second rotating column 14 through a rotating shaft, and the pull rod 17 is rotatably connected to a U-shaped telescopic frame 18 at one end away from the transmission frame 16 through a rotating shaft.

[0045] Specifically, after the wire reel is installed on the outside of the mounting column, the personnel rotate the transmission frame 16 by holding the second rotating column 14, and make the transmission frame 16 expand by using the rotating shaft to drive the pull rod 17, so that during the expansion process, the pull rod 17 uses the rotating shaft to push the U-shaped telescopic frame 18 to slide inside the fixed disk 6 and drive the first fixed block 19, and then the first fixed block 19 drives the mounting column and the wire reel away from the fixed disk 6 to adjust the position, and then the wire reel is misaligned with the wire reel on the right side of the fixed disk 6, so as to facilitate the adjustment of the position between the wire reels and avoid friction between the lead-out wires.

[0046] like Figure 7 and 8 As shown, cylinders 26 are rotatably connected to the inside of the first fixed block 19 at both ends, and the cylinder 26 is located at one end of the inner cavity of the first fixed block 19 and is fixedly connected to a gear 27 on the outside. The inner cavity wall of the first fixed block 19 is fixedly connected to the second fixed block 29 and the protective box 30 respectively, and the second fixed block 29 and the protective box 30 are close to each other at one end and are rotatably connected to a stop block 28 through a connecting shaft 31, and the stop block 28 is meshed with the gear 27. The connecting shaft 31 is located at one end of the inner cavity of the protective box 30 and is fixedly connected to a rotating disk 33 on the outside. The inner cavity wall of the protective box 30 is fixedly connected to a torsion spring 32, and the torsion spring 32 is fixedly connected to the rotating disk 33 at one end away from the inner cavity wall of the protective box 30, and the end of the cylinder 26 away from the first fixed block 19 is fixedly connected to an expansion component.

[0047] Specifically, when the external winding equipment pulls the wire for twisting, the wire will drive the wire drum and the mounting column 25 to rotate, and at the same time the mounting column 25 drives the cylinder 26 to rotate outside the first fixed block 19, so that the cylinder 26 drives the gear 27 during rotation, and the gear 27 drives the block 28 to rotate during rotation. After the twisting is completed, the torsion spring 32 in the inner cavity of the protective box 30 will cooperate with the rotating disk 33 to reset the twisted connecting shaft 31, so that the connecting shaft 31 rotates the block 28 to reset and engage the gear 27, thereby stopping the gear 27 urgently, avoiding the situation where the mounting column 25 drives the cylinder 26 to rotate and the wire is reversed, which makes it inconvenient for workers to sort the wires later and affects the processing efficiency of the twisting.

[0048] like Figure 7 and 8 As shown, the expansion assembly includes a mounting column 25, the inner cavity of the mounting column 25 is rotatably connected to a bidirectional threaded rod 20 through a bearing, the outer thread of the bidirectional threaded rod 20 is connected to an H-shaped sliding plate 21, the inner cavity of the H-shaped sliding plate 21 is rotatably connected to a push rod 22 through a rotating shaft, the push rod 22 is rotatably connected to a U-shaped connecting block 24 at one end away from the inner cavity of the H-shaped sliding plate 21 through a rotating shaft, and the U-shaped connecting block 24 is fixedly connected to a semicircular pushing plate 23 at one end away from the pushing rod 22.

[0049] Specifically, after the personnel places the wire bobbin outside the mounting column 25, the bidirectional threaded rod 20 is rotated to threadably drive the H-shaped slide plate 21 to be slidably connected in the inner cavity of the mounting column 25, and the H-shaped slide plate 21 is expanded by using the rotating shaft to drive the pushing rod 22, and at the same time, the pushing rod 22 uses the rotating shaft to cooperate with the U-shaped connecting block 24 to push the semicircular pushing plate 23 to squeeze and fix the wire bobbin outside the mounting column 25, thereby realizing the ability to quickly install, disassemble and replace the wire bobbin.

[0050] like Figure 3 and 4 As shown, a tension adjustment component is arranged inside the first capstan 34, and the tension adjustment component includes a slide groove 43 evenly arranged on the outside of the first capstan 34, a tension spring 45 is fixedly connected to the bottom of the inner cavity of the slide groove 43, and the tension spring 45 is fixedly connected to a support rod 44 at one end away from the bottom of the inner cavity of the slide groove 43, and the outside of the support rod 44 is evenly provided with wire arrangement holes 46.

[0051] Specifically, during the process of twisting the wires, the tension spring 45 in the inner cavity of the slide groove 43 is used to pull the support rod 44, and the support rod 44 pulls the wires closer to each other through the wire arrangement hole 46, so as to avoid the wire arrangement angle being too large during the twisting process, thereby affecting the density between the multiple wires when they are twisted into a main line, resulting in unstable conductivity of the finished cable in the later stage.

[0052] like Fig. 9As shown, the second capstan 35 is provided with an anti-backflow assembly, which includes a receiving groove 37 evenly arranged inside the second capstan 35, a spring 38 is fixedly connected to the bottom of the inner cavity of the receiving groove 37, and a slide bar 39 is fixedly connected to one end of the spring 38 away from the bottom of the inner cavity of the receiving groove 37, a through hole 40 is provided on the outside of the slide bar 39 and is connected to the strand hole 36, a pulling groove 42 is evenly arranged on the right side of the second capstan 35, and the pulling groove 42 is connected to the receiving groove 37, a pulling block 41 is slidably connected to the inner cavity of the pulling groove 42, and the pulling block 41 is located at one end of the receiving groove 37 and is fixed to the slide bar 39.

[0053] Specifically, after the wire twisting is completed, the personnel will cut the wires, and then use the spring 38 in the inner cavity of the storage groove 37 to push the slide bar 39, and make the slide bar 39 use the through hole 40 to cooperate with the twisting hole 36 to squeeze and fix the remaining wires, thereby further preventing the remaining wires from being bent, and avoiding the trouble of wasting a lot of time manually to re-arrange the wires in the later stage.

[0054] like Figure 1 As shown, a fixing rod 7 is fixedly connected to the right side of the upper end of the base 1, and a wire reel 8 is fixedly connected to the end of the fixing rod 7 away from the base 1, and a limiting hole 9 is arranged inside the wire reel 8.

[0055] Specifically, during the process of twisting the wires, the wires are limited by using the limiting holes 9 so that the wires can pass through the limiting holes 9 smoothly for winding.

[0056] Working principle: after the staff prevents the wire spool from being outside the mounting column 25, they rotate the bidirectional threaded rod 20 to thread the H-shaped sliding plate 21 to slide and connect it in the inner cavity of the mounting column 25, and make the H-shaped sliding plate 21 expand by driving the push rod 22 through the rotating shaft, and at the same time make the push rod 22 push the semicircular push plate 23 to squeeze and fix the wire spool outside the mounting column 25 by the rotating shaft and the U-shaped connecting block 24, thereby realizing the ability to quickly install, disassemble and replace the wire spool; and after the wire spool is installed outside the mounting column 25, the staff rotates the first rotating column 13 by holding the first rotating column 13. The transmission frame 16 is used to expand the transmission frame 16 by using the rotating shaft to drive the pull rod 17, so that the pull rod 17 uses the rotating shaft to push the U-shaped telescopic frame 18 to slide inside the fixed disk 6 during the expansion process, and drives the first fixed block 19, so that the first fixed block 19 uses the cylinder 26 to cooperate with the mounting column 25 to drive the wire drum away from the fixed disk 6 to adjust the position, and then the wire drum is misaligned with the wire drum on the right side of the fixed disk 6, so as to avoid friction between the wires when the external winding device pulls the external wires of the wire drum for twisting, thereby affecting the life of the finished cable in the later stage;

[0057] Then the personnel pull the wire outside the wire drum through the wire arrangement hole 46 and the twisting wire hole 36 to gather at the limit hole 9, and install and connect with the external winding device, and then start the driving motor 11 to rotate the first sprocket 3 transmission chain 4 to drive the second sprocket 5 while the external winding device rotates the traction wire, and the second sprocket 5 rotates the connecting column 15 to drive the fixed disk 6, so that the fixed disk 6 uses the fixed column 10 to rotate the first capstan 34 and the second capstan 35 to drive multiple wires to twist to form a main line during the rotation process;

[0058] When the external winding device pulls the wire for stranding, the wire drives the wire drum and the mounting column 25 to rotate, and the mounting column 25 drives the cylinder 26 to rotate outside the first fixed block 19, so that the cylinder 26 drives the gear 27 during the rotation, and the gear 27 drives the block 28 to rotate during the rotation. After the stranding is completed, the torsion spring 32 in the inner cavity of the protection box 30 cooperates with the rotating disk 33 to reset the twisted connecting shaft 31, so that the connecting shaft 31 rotates the block 28 to reset and mesh with the gear 27, thereby stopping the gear 27 urgently, avoiding the situation that the mounting column 25 drives the cylinder 26 to rotate and reverse the wire, which makes it inconvenient for workers to sort out the wires later and affects the processing efficiency of the stranding.

[0059] After the wires are twisted, the personnel cut the wires, and then use the spring 38 in the inner cavity of the storage groove 37 to push the slide bar 39, and use the through hole 40 and the twisting hole 36 to squeeze and fix the remaining wires, thereby further preventing the remaining wires from being bent and avoiding a lot of time wasted on manually arranging the wires later.
