Description

Technical Field

[0001] The present invention relates to the technical field of electric wire production, in particular to a wire stranding device for electric wire production. Background Art

[0002] Wires usually refer to products consisting of a single or a few conductors (such as copper or aluminum) plus a simple insulation layer (such as PVC). They have a relatively simple structure and are mainly used for short-distance, low-power power transmission or signal transmission. Stranded wire refers to a processing technology that winds multiple single-strand wires (usually conductive materials such as copper and aluminum, and may also include insulated cores) into a bundle according to certain rules (such as spiral direction and pitch).

[0003] However, the prior art still has the following problems:

[0004] In terms of structural stability and power transmission, existing wire stranding equipment for wire production lacks a suitable friction-reducing structure during shaft rotation, resulting in high rotational friction and a tendency for jamming to occur, affecting smooth rotation. Furthermore, there is a lack of effective position limits on related supporting components, which can easily cause component displacement and poor rotational stability. Furthermore, the connection between the core components and the main body of the equipment is fixed and difficult to adjust, which can easily affect power transmission and, in turn, the quality of the stranded wire.

[0005] Secondly, existing wire stranding equipment for wire production suffers from a limited adaptability due to its single adjustment mechanism. This makes it difficult to flexibly adjust the position of the limiting components based on the size of the wire reel, making it difficult to adapt to reels of varying sizes. There is also a lack of effective adjustment methods for the positions of crossbars and core rotating components, making it difficult to effectively address diverse wire stranding production requirements and resulting in low versatility.

[0006] Furthermore, existing wire stranding equipment for wire production struggles with ease of operation. Components often use fixed connections, making disassembly and adjustment difficult, and inconvenient for installation, repair, and replacement. Adjusting the height of the wire guides is complex and cumbersome, making it difficult to quickly adjust the guide height to meet production needs, impacting production efficiency.

[0007] In response to the above problems, the inventors proposed a wire stranding device for wire production to solve the above problems. Summary of the Invention

[0008] In order to solve the problems of poor structural stability and power transmission, low adaptability and insufficient operation convenience of existing wire stranding equipment for wire production, the purpose of the present invention is to provide a wire stranding equipment for wire production.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions: A stranding device for electric wire production, comprising a bottom plate, an upper plate fixedly provided on the upper side of the bottom plate, and a shell fixedly provided on the upper surface of the upper plate, a cross provided on one side of the shell, and four cross bars distributed in a ring shape provided on the inner side of the cross, a short rod provided on one side of the cross bar for damping sliding, and a support rod fixed on one side of the short rod, an L-shaped limit plate fixed on the end of the support rod, a rotating shaft provided on the upper side of the shell, a limit groove provided on one side of the cross, the rotating shaft sleeved in the limit groove, a circular ring provided on the outer surface of the rotating shaft, a cover plate fixed on one side of the circular ring, four circularly distributed plugs fixedly inserted on the outer surface of the circular ring, and two limit shafts rotatably provided on the outer end of the plug, the four circularly distributed cross bars on the inner side of the cross are important support structures for the installation of the wire reel. The cross bars and the cross are connected by means of a card slot, which makes the installation and disassembly of the cross bars very convenient. When you need to replace wire reels of different specifications or adjust the number of wire reels, you only need to remove the cross bar from the slot to quickly complete the adjustment. This design breaks the limitations of traditional fixed connections and greatly improves the flexibility of the equipment to meet different production needs. The short rod on one side of the cross bar adopts a damping sliding design, which provides the possibility of fine adjustment for the wire reel limit. The short rod can slide stably without shaking at will through the cooperation of the T-slot and the card block. When installing the wire reel, the operator can push the short rod to slide on the cross bar according to the width of the wire reel, thereby driving the support rod and the L-shaped limit plate to move until the L-shaped limit plate just fits the edge of the wire reel to achieve precise limit of the wire reel.

[0010] Preferably, a bearing is provided on the outer surface of the rotating shaft, and a limiting sleeve is connected to the outer surface of the rotating shaft by bolts. A limiting cross column is fixed on one side of the cross, and an arc-shaped movable groove for cooperating with the limiting cross column is provided on one side of the circular ring. The cross and the shell are connected by bolts, and a bolt movable groove for cooperating with the bolt is symmetrically provided on one side of the cross. The rotating shaft is the core rotating component of the equipment, and its stability directly affects the quality of the stranded wire. The rotating shaft sleeve is arranged in the limiting groove of the cross, and the limiting groove plays a preliminary radial limiting role on the rotating shaft, preventing the rotating shaft from having excessive radial deviation during rotation. The circular ring sleeve is arranged on the outer surface of the rotating shaft, and the cover plate on one side of it can effectively prevent dust, debris, etc. from entering the connection part between the rotating shaft and the cross, avoiding these impurities from affecting the smoothness of rotation. The four annularly distributed plugs on the outer surface of the circular ring, and the two limiting shafts at its ends will contact the outer edge of the wire drum during operation. Since the limit shaft is set to rotate, when the wire drum rotates, the limit shaft will rotate accordingly, converting the sliding friction between the wire drum and the limit component into rolling friction, which not only reduces friction loss, but also further limits the shaking of the wire drum, making the wire drum rotate more smoothly.

[0011] Preferably, a servo motor is bolted to the upper surface of the base plate, and a drive shaft is fixedly mounted on the output terminal of the servo motor. A transmission belt is sleeved on the outer surface of the drive shaft, and a driven shaft is sleeved on the inner surface of the transmission belt. One side of the driven shaft is fixedly connected to the rotating shaft. Stoppers are symmetrically fixed to the upper surface of the housing, and the rotating shaft is sleeved within the stoppers. Both the upper plate and the housing have mating grooves for mating with the transmission belt. The efficient and stable power transmission system ensures the normal operation of the equipment. The servo motor is bolted to the base plate, providing a secure fixation that is both secure and easy to maintain and replace. When the servo motor is operating, the drive shaft rotates the driven shaft via the transmission belt, which in turn drives the rotating shaft. The transmission belt is sleeved on the outer surfaces of the drive and driven shafts. The mating grooves on the upper plate and the housing provide adequate space for the transmission belt, preventing friction and interference between the transmission belt and other components during operation. Furthermore, the stoppers on the upper surface of the housing provide auxiliary support for the rotating shaft, preventing significant deflection during high-speed rotation and ensuring stable power transmission. Compared with gear transmission, this transmission method has the advantages of low noise and easy maintenance, which can effectively reduce the operating noise and maintenance costs of the equipment.

[0012] Preferably, a vertical plate is fixedly provided on one side of the upper surface of the upper plate, and a rotating column is rotatably provided on one side of the vertical plate, a driving bevel gear is fixedly provided on the end of the rotating column, the outer surface of the driving bevel gear is meshedly connected with a driven bevel gear, a lead screw is fixedly provided on the lower surface of the driven bevel gear, and a lifting support plate is threadedly provided on the outer surface of the lead screw, and a V-shaped groove is provided on the upper surface of the lifting support plate.

[0013] Preferably, two columns are fixedly mounted on one side of the upper surface of each of the base plate and the housing, and a shaft is movably mounted on the outer surface of the columns. The design of the wire guide structure fully considers tension control during the stranding process. When the column on the base plate rotates, it drives the driving bevel gear to rotate. The driving bevel gear meshes with the driven bevel gear, converting the horizontal rotation into vertical rotation of the lead screw. When the lead screw rotates, the lifting support plate threadedly connected to it moves up and down along the lead screw, thereby adjusting the height of the V-shaped groove. During the stranding process, the operator can quickly adjust the height of the V-shaped groove by rotating the column according to the thickness of the wire and the required tightness of the strand, ensuring that the wire always maintains the appropriate tension. The V-shaped groove design effectively limits the wire, preventing it from shifting left or right during transmission and ensuring that the wire accurately enters the stranding area. The columns on the base plate and the housing cooperate with the shaft, which can slide freely on the column and flexibly adjust its position according to the wire transmission path, further assisting in wire guidance and preventing problems such as entanglement and knotting.

[0014] Preferably, a card slot is provided on the outer surface of the cross, and the cross bar is clamped in the corresponding card slot, a T-shaped slot is provided on the inner side of the cross bar, a card block is fixedly provided on the outer end of the short bar, and the card block is clamped in the corresponding T-shaped slot, a through-type through slot is provided on one side of the short bar, the support rod is inserted in the corresponding through slot, and the through slot and the support rod are fixedly connected by bolts, a mounting block is fixedly provided on one side of the L-shaped limiting plate, and the mounting block and the corresponding support rod are fixedly connected by bolts.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a bearing on the outer surface of the rotating shaft, which reduces the friction when the rotating shaft rotates and ensures the smoothness of rotation; the limit sleeve limits the bearing to prevent the bearing from being displaced on the rotating shaft; the cross is connected to the shell by bolts, and there are movable bolt grooves to adjust the position, so the connection is stable and easy to adjust; the power provided by the servo motor is stably transmitted through the transmission belt, ensuring the stability of the rotation of the core components of the entire equipment and providing a basic guarantee for the quality of the stranded wire.

[0017] 2. This invention utilizes a damped sliding fit between the crossbar and the short rod, allowing the position of the L-shaped limit plate to be flexibly adjusted according to the size of the reel. Combined with the limit shaft at the end of the plug post, it can accommodate the securing requirements of reels of varying sizes. The slots on the crossbar and the bolt slots adjust the position of the crossbar. These multiple adjustment mechanisms allow the equipment to meet diverse stranding production requirements, enhancing its versatility.

[0018] 3. The various components of the present invention mostly adopt detachable and adjustable connection methods such as bolt connection, such as the clamping connection between the cross bar and the cross, the sliding connection between the short bar and the cross bar, etc., which are convenient for the installation, disassembly and adjustment of the components; the height of the lifting support plate is adjusted by structures such as rotating columns and screws, which is simple and convenient to operate, and can quickly change the wire guide height according to production needs.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example: Figure 1-8As shown, the present invention provides a stranding device for electric wire production, comprising a bottom plate 1, an upper plate 2 is fixedly provided on the upper side of the bottom plate 1, and a shell 3 is fixedly provided on the upper surface of the upper plate 2, a cross 4 is provided on one side of the shell 3, and four cross bars 6 distributed in an annular shape are provided on the inner side of the cross 4, a short rod 61 is provided on one side of the cross bar 6 for damping sliding, and a support rod 62 is fixed on one side of the short rod 61, and an L-shaped limit plate 63 is fixed on the end of the support rod 62, a rotating shaft 5 is provided on the upper side of the shell 3, a limiting groove 41 is provided on one side of the cross 4, the rotating shaft 5 is sleeved in the limiting groove 41, a circular ring 7 is provided on the outer surface of the rotating shaft 5, a cover plate 71 is fixed on one side of the circular ring 7, four plug posts 73 distributed in an annular shape are fixedly inserted on the outer surface of the circular ring 7, and two limiting shafts 74 are rotatably provided on the outer end of the plug post 73, and the limiting shaft 74 at the end of the plug post 73 on one side of the circular ring 7 can further limit the wire drum from other directions to ensure that the wire drum will not deviate during rotation. Fixed to one side of the ring 7, it shields and protects the connection between the ring 7 and the cross 4. This prevents debris and dust generated during the twisting process from entering the retaining groove 41, the arc-shaped movable groove 72, and other mating structures, thereby preventing smooth rotation. It also reduces interference from foreign matter with the wires near the reel, thereby improving the overall safety of the equipment.

[0031] A bearing 52 is provided on the outer surface of the rotating shaft 5, and a limiting sleeve 53 is connected to the outer surface of the rotating shaft 5 by bolts. A limiting cross column 51 is fixed on one side of the cross 4, and an arc-shaped movable groove 72 is provided on one side of the ring 7 to cooperate with the limiting cross column 51. The cross 4 and the shell 3 are connected by bolts, and a bolt movable groove 42 for cooperating with the bolts is symmetrically provided on one side of the cross 4. The bearing 52 is sleeved on the outer surface of the rotating shaft 5, which greatly reduces the friction resistance between the rotating shaft 5 and the contact parts when the rotating shaft 5 rotates, ensures the stability of the rotating shaft 5 when rotating at high speed, and reduces the wear and energy consumption caused by friction; the limiting sleeve 53 is fixed to the rotating shaft 5 by bolts, which can accurately limit the axial position of the bearing 52 on the rotating shaft 5, prevent the bearing 52 from being displaced due to vibration or force, and ensure that it is always in the best support state.

[0032] The upper surface of the base plate 1 is bolted to the servo motor 11, and the output short of the servo motor 11 is fixed with a drive shaft 12, the outer surface of the drive shaft 12 is sleeved with a transmission belt 13, and the inner surface of the transmission belt 13 is sleeved with a driven shaft 15, one side of the driven shaft 15 is fixedly connected to the rotating shaft 5, and a limit piece 16 is symmetrically fixed on the upper surface of the shell 3. The rotating shaft 5 is sleeved in the limit piece 16, and one side of the upper plate 2 and the shell 3 is provided with a matching groove 14 for matching with the transmission belt 13. After the servo motor 11 is started, the drive shaft 12 at its output end starts to rotate, and the drive shaft 12 drives the driven shaft 15 to rotate through the transmission belt 13 on the outer surface. Since the driven shaft 15 is fixedly connected to the rotating shaft 5, the rotating shaft 5 rotates accordingly. During the rotation process, the rotating shaft 5 is limited by the limit piece 16 to ensure the stability of the rotation. At the same time, the cross 4 sleeved on the outer surface of the rotating shaft 5 rotates synchronously under the drive of the rotating shaft 5, providing a rotational power basis for the subsequent twisting operation.

[0033] A vertical plate 21 is fixed on one side of the upper surface of the upper plate 2, and a rotating column 22 is rotatably provided on one side of the vertical plate 21. A driving bevel gear 23 is fixed on the end of the rotating column 22. The outer surface of the driving bevel gear 23 is meshed with a driven bevel gear 24. A screw 25 is fixed on the lower surface of the driven bevel gear 24, and a lifting support plate 8 is provided on the outer surface of the screw 25. A V-shaped groove 81 is provided on the upper surface of the lifting support plate 8. When the cross 4 rotates with the rotating shaft 5, the wire drum rotates accordingly, and the wire is drawn out from the wire drum. In this process, the rotating shaft 5 drives the ring 7 to rotate, and the arc on one side of the ring 7 The V-shaped movable groove 72 cooperates with the limiting horizontal column 51 on the cross 4 to ensure the stability of the rotation of the ring 7. At the same time, after the wire is led out, it will pass through the V-shaped groove 81 on the lifting support plate 8. The V-shaped groove 81 guides the wire. By rotating the rotating column 22, the driving bevel gear 23 is driven to rotate, and the driving bevel gear 23 engages to drive the driven bevel gear 24 to rotate, thereby rotating the lead screw 25, and the lead screw 25 drives the lifting support plate 8 to rise and fall. The guide height of the wire can be adjusted according to actual needs to ensure that the wire maintains appropriate tension and direction during the stranding process, and finally completes the stranding operation.

[0034] Two columns 9 are fixedly mounted on one side of the upper surface of each of the base plate 1 and the housing 3. A shaft 91 is movably mounted on the outer surface of each column 9. The columns 9 on the upper surface of the base plate 1 and the housing 3 provide a mounting support for the shaft 91. The shaft 91 is movably mounted on the outer surface of the columns 9 and can be adjusted along the axial direction of the columns 9. Its main function is to assist in guiding the wires drawn out during the stranding process, preventing them from excessively sagging or deflecting due to lack of support during the transmission path. In conjunction with the V-grooves 81 of the lifting support plate 8, the transmission stability of the wires is further optimized. This is particularly suitable for diverting and limiting the flow of multiple wires during the synchronous stranding process.

[0035] A card slot 64 is provided on the outer surface of the cross 4, and the cross bar 6 is clamped in the corresponding card slot 64, a T-shaped slot 611 is provided on the inner side of the cross bar 6, and a card block 612 is fixed on the outer end of the short rod 61, and the card block 612 is clamped in the corresponding T-shaped slot 611. A through-type through slot 621 is provided on one side of the short rod 61, and the support rod 62 is inserted in the corresponding through slot 621, and the through slot 621 and the support rod 62 are fixedly connected by bolts. A mounting block 631 is fixed on one side of the L-shaped limiting plate 63, and the mounting block 631 and the corresponding support rod 62 are fixedly connected by bolts. Before stranding, the relevant components are adjusted according to the specifications of the wire drum to be stranded. By sliding the short rod in the T-shaped slot 611 of the cross bar 6 The clamping block 612 of 61 can adjust the position of the short rod 61, and then change the position of the support rod 62 and the L-shaped limiting plate 63, so that the L-shaped limiting plate 63 can adapt to wire reels of different sizes and perform preliminary limiting on them. The through groove 621 on one side of the short rod 61 provides installation and adjustment space for the support rod 62, and the support rod 62 is fixed to the through groove 621 by bolts, and the extension length of the support rod 62 can be fine-tuned according to the radial size of the wire reel; the L-shaped limiting plate 63 is bolted to the support rod 62 by the mounting block 631, which is not only convenient for disassembly and replacement of the L-shaped limiting plate 63 (such as replacing the adaptive limiting plate according to different wire reel edge shapes), but also can further optimize the limiting accuracy of the L-shaped limiting plate 63 on the reel by adjusting the fixed position of the mounting block 631.

[0036] Among them, the servo motor 11 is a prior art and will not be described in detail. At the same time, the present invention also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0037] Working principle: After the servo motor 11 is started, the drive shaft 12 at its output end begins to rotate. The drive shaft 12 drives the driven shaft 15 to rotate through the transmission belt 13 on the outer surface. Since the driven shaft 15 is fixedly connected to the rotating shaft 5, the rotating shaft 5 rotates accordingly. During the rotation process, the rotating shaft 5 is limited by the limiter 16 to ensure the stability of the rotation. At the same time, the cross 4 mounted on the outer surface of the rotating shaft 5 rotates synchronously under the drive of the rotating shaft 5, providing the rotational power basis for the subsequent stranding operation.

[0038] Before stranding, the relevant components are adjusted according to the specifications of the reel of the wire to be stranded. The position of the short rod 61 can be adjusted by sliding the block 612 of the short rod 61 in the T-slot 611 of the crossbar 6, thereby changing the position of the support rod 62 and the L-shaped limiting plate 63, so that the L-shaped limiting plate 63 can adapt to reels of different sizes and perform preliminary positioning. In addition, the limiting shaft 74 at the end of the plug post 73 on one side of the ring 7 can further limit the reel in other directions to ensure that the reel will not deviate during the rotation process;

[0039] When the cross 4 rotates with the rotating shaft 5, the wire drum rotates accordingly, and the wire is drawn out from the wire drum. During this process, the rotating shaft 5 drives the ring 7 to rotate, and the arc-shaped movable groove 72 on one side of the ring 7 cooperates with the limiting horizontal column 51 on the cross 4 to ensure the stability of the rotation of the ring 7. At the same time, after being drawn out, the wire will pass through the V-shaped groove 81 on the lifting support plate 8. The V-shaped groove 81 guides the wire and drives the driving bevel gear 23 to rotate by rotating the rotating column 22. The driving bevel gear 23 engages and drives the driven bevel gear 24 to rotate, thereby rotating the lead screw 25. The lead screw 25 drives the lifting support plate 8 to rise and fall. The guide height of the wire can be adjusted according to actual needs to ensure that the wire maintains appropriate tension and direction during the stranding process, and finally completes the stranding operation;

[0040] If it is necessary to adapt to different stranded wire requirements, it can be adjusted through relevant structures. The cross 4 and the shell 3 are connected by bolts, and a bolt movable groove 42 is provided on the cross 4. The position of the cross 4 can be adjusted after loosening the bolt. In addition, the cross bar 6 is clamped in the clamping groove 64 of the cross 4, and the position of the cross bar 6 can also be adjusted as needed to adapt to different wire reel installation requirements.

[0041] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
