Description

Technical Field

[0001] This utility model relates to the field of stranding machine technology, and in particular to an automatic cleaning device for stranding machines. Background Technology

[0002] Currently, stranding machines are core equipment in fields such as wires and cables, communication cables, and electrical equipment connection wires. Their main function is to strand multiple single-strand wires into strands or cable cores with specific mechanical strength and electrical properties according to a preset stranding process, ensuring that the final product meets the requirements for transmission stability, tensile strength, and other uses. During the stranding production process, the cleanliness of the wire surface directly affects the stranding quality and the performance of the finished product. If dust, oil, metal shavings, or other impurities remain on the wire surface, they will be trapped inside the strands during the stranding process. This can not only lead to poor contact at the stranding points and reduced insulation resistance, but also weaken the overall mechanical strength of the strands, increasing the risk of wire breakage, short circuits, and other faults during subsequent use. Therefore, cleaning the wires before stranding is a key step in ensuring product quality. However, the current stranding machines on the market still have significant shortcomings in their cleaning function design, making it difficult to meet the needs of efficient and high-quality production.

[0003] The cleaning process is disconnected from the stranding process, resulting in poor production continuity. In existing technologies, most stranding machines do not integrate a synchronous cleaning mechanism, requiring a separate offline cleaning station before the stranding process: after the wire is released from the wire roller, it needs to be transferred manually or by additional conveying equipment to cleaning equipment (such as alcohol wiping devices or high-pressure air washing devices) for processing. During the transfer process, the wire is exposed to the workshop environment and is easily contaminated with airborne dust. At the same time, offline cleaning and subsequent stranding processes need to be controlled separately, resulting in waiting gaps (such as waiting for the previous stranding process to finish before the cleaning equipment finishes cleaning a batch of wire before feeding new wire), which leads to a longer overall production cycle and reduced efficiency.

[0004] Therefore, we propose an automatic cleaning device for stranding machines to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing an automatic cleaning device for stranding machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic cleaning device for a stranding machine includes: a stranding machine with a turntable rotatably mounted on it; several fixing components are mounted on the outside of the turntable, and each fixing component is equipped with a wire assembly for guiding the wire wound on the wire rollers; it also includes several cleaning cylinders, each corresponding to a wire assembly, and each cleaning cylinder is fixedly mounted on its corresponding wire assembly; each cleaning cylinder is equipped with a rotation mechanism, which drives the cleaning cylinder to rotate around its own axis. When the turntable drives multiple wire assemblies to rotate synchronously around its central axis under the action of external force, so that the wire released from the wire rollers of each wire assembly enters the stranding process, the rotation mechanism starts synchronously and drives each cleaning cylinder to rotate independently; when the cleaning cylinder rotates, its inner wall and the wire passing through it form a relative motion, and the cleaning treatment of the outer surface of the wire is completed through this relative motion.

[0008] Preferably, the conductor assembly includes a docking cylinder fixedly installed on the side wall of the fixing member, a bracket fixedly installed on the side wall of the docking cylinder, a wire outlet hole opened on the side wall of the bracket, and a stranding frame detachably installed on the other end of the bracket, with a stranding hole opened on the side wall of the stranding frame.

[0009] Preferably, a screw is installed through one side of the stranding frame, a material roller is fixedly installed at one end of the screw, and a first nut is threaded onto both ends of the screw, with two first nuts distributed on both sides of the stranding frame.

[0010] Preferably, each of the docking cylinders has a docking hole in the middle, and the docking hole is movably inserted into the other end of the material roller.

[0011] Preferably, the bracket has a plurality of positioning holes, and the stranded wire frame has two mounting holes. Bolts are installed in the corresponding mounting holes and positioning holes, and a second nut is threaded onto the other end of the bolt.

[0012] Preferably, the rotation mechanism includes support rings rotatably mounted at both ends of the outer side of the cleaning cylinder, the support rings being fixedly mounted on the side wall of the bracket, a cleaning brush being fixedly mounted on the inner wall of the cleaning cylinder, a gear being fixedly mounted on one side of the outer wall of the cleaning cylinder, and a gear ring meshing with multiple gears, the gear ring being fixedly mounted inside the support plate, and the support plate being fixedly mounted on the stranding machine.

[0013] Preferably, the stranding hole corresponds to the inner cavity of the cleaning tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a self-rotating mechanism that starts synchronously with the turntable rotation. This ensures that the cleaning process begins immediately as the wire is released from the wire roller and enters the stranding process, without requiring additional waiting or separate control. This completely prevents the wire from becoming contaminated with impurities before stranding, achieving a seamless connection between the stranding and cleaning processes and improving overall production continuity. The cleaning cylinder rotates independently around its own axis through the self-rotating mechanism, creating an active relative motion with the wire being stranded. Compared to a fixed cleaning structure, this method allows the inner wall of the cleaning cylinder to fully contact the surface of the wire. Even if the wire has slight twisting or misalignment, the self-rotation can compensate for the cleaning range, effectively removing surface dust, oil, and other impurities, and avoiding the problem of incomplete cleaning in certain areas.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6The automatic cleaning device for a stranding machine includes: a stranding machine 1, a turntable 11 rotatably mounted on the stranding machine 1, and several fixing parts 12 mounted on the outside of the turntable 11. Each fixing part 12 is equipped with a wire assembly for guiding the wire wound on the wire roller.

[0025] It also includes several cleaning cylinders 31, each corresponding to a wire assembly, and each cleaning cylinder 31 is fixedly mounted on its corresponding wire assembly. Each cleaning cylinder 31 is equipped with a rotation mechanism, which drives the cleaning cylinder 31 to rotate around its own axis. When the turntable 11 drives multiple wire assemblies to rotate synchronously around its central axis under the action of external force, so that the wires released by the wire rollers of each wire assembly enter the twisting process, the rotation mechanism starts synchronously and drives each cleaning cylinder 31 to rotate independently. When the cleaning cylinder 31 rotates, its inner wall and the wires passing through it form a relative motion, and the cleaning treatment of the outer surface of the wires is completed through this relative motion.

[0026] When the stranding machine 1 is started, power is transmitted to the turntable 11, causing it to rotate around its central axis. The fixing part 12, which is fixed on the outside of the turntable 11, rotates synchronously with the turntable 11, thereby driving the movement of each conductor assembly. The upper roller of the conductor assembly releases the wire, preparing it for the stranding process. At the same time, the power of the rotating part of the turntable 11 is transmitted to the self-rotating mechanism. The turntable 11 is equipped with a drive gear 32. The gear ring 35 in the self-rotating mechanism meshes with the drive gear 32. When the turntable 11 rotates, the drive gear 32 drives the gear ring 35 to rotate. The gear ring 35, through meshing with the gear 32 on the outer wall of the cleaning cylinder 31, drives the cleaning cylinder 31 to rotate independently around its own axis. The inner wall of the cleaning cylinder 31 forms relative motion with the wire passing through it. The inner wall is equipped with a cleaning brush 33, which rubs against the surface of the wire to remove dust, oil and other impurities, thus realizing the simultaneous operation of wire cleaning and stranding processes.

[0027] Furthermore, the conductor assembly includes a docking cylinder 13 fixedly installed on the side wall of the fixing member 12. A bracket 2 is fixedly installed on the side wall of the docking cylinder 13. A wire outlet hole 21 is opened on the side wall of the bracket 2. The position of the wire outlet hole 21 is adapted to the position of the end of the wire body wound on the outer peripheral wall of the wire roller, so that the end of the wire body can pass through the wire outlet hole 21. A stranding frame 22 is detachably installed on the other end of the bracket 2. A stranding hole 23 is opened on the side wall of the stranding frame 22.

[0028] When the wire roller releases the wire, the wire first enters the docking cylinder 13, which initially constrains the wire to ensure its stable output direction. Then, the wire is conveyed along the support 2, and the wire outlet hole 21 on the support 2 further regulates the wire's direction and limits its deviation range during transmission. When the wire reaches the stranding frame 22, the stranding hole 23 on the stranding frame 22 precisely guides the wire into the stranding process. The stranding frame 22 adopts a detachable design. When it is necessary to replace the stranding frame 22 with a different hole diameter, simply unscrew the bolts 28 and nuts that fix the stranding frame 22 to the support 2, and the original stranding frame 22 can be removed and a new suitable stranding frame 22 can be installed, achieving quick replacement to meet the production needs of different wires.

[0029] Furthermore, a screw 24 is installed through one side of the stranding frame 22, a feed roller 25 is fixedly installed at one end of the screw 24, a wire roller is sleeved on the outside of the feed roller 25, and a first nut 26 is threaded on both ends of the screw 24, with two first nuts 26 distributed on both sides of the stranding frame 22.

[0030] When installing the material roller 25, the screw 24 passes through the stranding frame 22, and the roller is fitted onto the screw 24. The first nut 26 is screwed onto both ends of the screw 24. During the tightening process, the two nuts apply pressure to the material roller 25 from both sides of the stranding frame 22, forming a bidirectional fixing effect. This effectively counteracts the vibration and impact generated during the operation of the device, ensuring the stable installation of the material roller 25 and preventing axial displacement or radial sway due to vibration. This ensures that the speed at which the roller releases the wire is uniform. When it is necessary to replace the roller with one of different materials and diameters, the operator only needs to loosen the first nut 26 at both ends to remove the material roller 25 from the stranding frame 22, replace it with a new roller, and then tighten the nut again to complete the quick material replacement operation.

[0031] Furthermore, each of the docking cylinders 13 has a docking hole 14 in the middle, which is movably inserted into the other end of the material roller 25.

[0032] One end of the material roller 25 is fixedly connected to the stranding frame 22 via a screw 24, and the other end is inserted into the docking hole 14 of the docking cylinder 13, forming a two-point support structure. When the material roller 25 rotates around its own axis, the support points at both ends work together to limit the radial runout of the material roller 25, control the runout within a very small range, and ensure that the material roller 25 rotates smoothly. When installing the material roller 25, the operator first aligns one end of the material roller 25 with the docking hole 14 of the docking cylinder 13 and inserts it to achieve quick positioning. Then, the screw 24 passes through the stranding frame 22 and connects to the other end of the material roller 25, and the nut is tightened to fix it. When disassembling, the nut is loosened first, and then the material roller 25 is pulled out axially. The operation process is simple and reduces the difficulty of installing and disassembling the material roller 25.

[0033] Furthermore, the bracket 2 has several positioning holes 27, and the stranded wire frame 22 has two mounting holes. Bolts 28 are installed in the corresponding mounting holes and positioning holes 27, and a second nut 29 is threaded onto the other end of the bolt 28.

[0034] The stranding frame 22 is connected to the bracket 2 by bolts 28 and nuts. The bracket 2 has multiple positioning holes 27, and the stranding frame 22 has corresponding mounting holes. When it is necessary to adjust the position of the stranding frame 22, the operator loosens the bolts 28 and nuts, removes the bolts 28 from the original positioning holes 27, inserts them into the appropriate positioning holes 27, and then tightens the nuts to change the lateral or longitudinal position of the stranding frame 22.

[0035] Furthermore, the self-rotating mechanism includes support rings 3 rotatably mounted at both ends of the outer side of the cleaning cylinder 31. The inner wall of the support rings 3 is fixedly connected to the outer shaft of the bearing, and the outer wall of the cleaning cylinder 31 is fixedly connected to the inner shaft of the bearing. The support rings 3 are fixedly mounted on the side wall of the bracket 2. A cleaning brush 33 is fixedly mounted on the inner wall of the cleaning cylinder 31. A gear 32 is fixedly mounted on one side of the outer wall of the cleaning cylinder 31. A toothed ring 35 meshes with multiple gears 32. The toothed ring 35 is fixedly mounted inside the support plate 34. The support plate 34 is fixedly mounted on the stranding machine 1.

[0036] The support rings 3 at both ends of the outer side of the cleaning cylinder 31 are fixed to the bracket 2, providing stable rotational support for the cleaning cylinder 31 and ensuring that its axial position is stable when the cleaning cylinder 31 rotates, reducing radial offset. The cleaning brush 33 fixed on the inner wall of the cleaning cylinder 31 is made of flexible and wear-resistant material. When the cleaning cylinder 31 rotates, the cleaning brush 33 contacts and rubs against the surface of the wire to remove impurities from the surface of the wire. The gear 32 installed on one side of the outer wall of the cleaning cylinder 31 meshes with the toothed ring 35 fixed on the support plate 34. When the turntable 11 drives the wire assembly to rotate around the central axis, the cleaning cylinder 31 moves accordingly, and the gear 32 on its outer wall rolls along the toothed ring 35. Through the transmission relationship of the meshing gear 32, the cleaning cylinder 31 is automatically driven to rotate. No additional power source is required. The original power of the turntable 11 is used to realize the synchronous rotation of the cleaning cylinder 31, saving energy and simplifying the structure of the device.

[0037] Furthermore, the twisted wire hole 23 corresponds to the inner cavity of the cleaning tube 31.

[0038] After the wire is led out from the stranding hole 23 of the stranding frame 22, it can enter the inner cavity of the cleaning tube 31 straight and smoothly due to the corresponding positions of the two. No additional posture adjustment is required, which avoids jamming and wire breakage caused by deviation and friction with the edge of the cleaning tube 31. After entering the cleaning tube 31, the wire is in the center of the inner cavity. The cleaning brush 33 on the inner wall of the cleaning tube 31 can wrap the surface of the wire in all directions. No matter how the wire is transmitted, the cleaning brush 33 can fully contact all parts of the wire, thoroughly eliminate cleaning dead corners, and efficiently remove impurities, providing high-quality cleaned wire for the subsequent stranding process.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
