Description

Technical Field

[0001] This utility model relates to the field of twisting machine technology, and in particular to a twisting machine. Background Technology

[0002] A stranding machine is a specialized processing device that twists multiple monofilaments or single strands into stable strands, ropes, or cables by setting the twist pitch and direction. It can be broadly defined as an automated or semi-automated production line consisting of a transmission device, a twisting machine body (including a stranding drum), a wire pressing device, a traction device, a take-up and winding device, and a safety control device. Specifically, the core working logic of this equipment is as follows: the stranding drum, as the core wire-feeding component, contains multiple wire rollers (I-beams), each corresponding to a single monofilament or single strand to be twisted.

[0003] The core flaw of existing stranding machines lies in the integrated design of the stranding drum, resulting in poor equipment adaptability, inconvenient maintenance and transportation, and difficulty in meeting diverse production needs. Because different specifications of stranded wire products (such as stranding wires of different numbers and diameters) require corresponding capacity and number of rollers, this integrated design presents multiple problems. If a roller inside the stranding drum malfunctions (such as wire breakage or roller jamming), the entire machine must be stopped and the entire stranding drum disassembled for repair, leading to prolonged downtime and impacting production efficiency. Furthermore, the integrated stranding drum is larger and heavier, requiring more space during transportation, and is prone to deformation due to impacts, affecting subsequent accuracy. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a twisting machine to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a stranding machine, including a horizontally arranged support plate, several linearly arrayed strand drum bodies, and several linearly arrayed couplings. The strand drum bodies and couplings are staggered, with each pair of adjacent strand drum bodies connected by a coupling. Several linearly arrayed assembly plates are fixedly mounted on the support plate by bolts. The strand drum bodies and assembly plates correspond vertically. Two symmetrically arranged bearing brackets are fixedly mounted on the top of each assembly plate by bolts. The two ends of each strand drum body are rotatably connected to the two bearing brackets by bearings. A corrugated hose is fixedly connected to one side of each strand drum body, and a locking ring is fixedly connected to one end of the corrugated hose. The side of the locking ring away from the corrugated hose is in contact with the strand drum body. Several circumferentially arrayed locking bolts are rotatably connected to one side of the locking ring, and the threaded portions of the locking bolts are threadedly connected to the strand drum body.

[0007] Preferably, one side of the main body of the stranded drum has a plurality of circumferentially arranged threaded holes, and the screw portions of the plurality of locking bolts are threadedly connected to the main body of the stranded drum through the threaded holes.

[0008] Preferably, the top surface of the support plate is provided with a plurality of linearly arrayed assembly slots, and a plurality of assembly plates are respectively inserted into the plurality of assembly slots, wherein the thickness of the assembly plate is equal to that of the assembly slot.

[0009] Preferably, in any of the above solutions, a plurality of symmetrically arranged positioning pins are fixedly connected to the top surface of each assembly plate, and the plurality of positioning pins are inserted into the interior of the assembly slot.

[0010] Preferably, in any of the above embodiments, a protective frame is fixedly installed on the top surface of each assembly plate by bolts, the main body of the stranded drum is located inside the protective frame, and the protective frame is located between two bearing frames.

[0011] Preferably, in any of the above embodiments, the protective frame is fixedly connected to both the left and right ends, and a clamping plate is fixedly connected to the bottom of each support frame, with the two clamping plates respectively inserted into the top of the two bearing frames.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. When a fault occurs in the internal roller of a stranded drum body, it is not necessary to disassemble the entire structure: First, loosen the locking bolt on one side of the locking ring so that the threaded part of the locking bolt disengages from the threaded hole of the stranded drum body, and remove the locking ring and the corrugated hose; then the connection of the coupling can be inspected. If the entire stranded drum body needs to be replaced, simply remove the connecting bolts between the assembly plate and the bearing plate, remove the assembly plate along with the top bearing bracket and the stranded drum body from the assembly slot, and replace it with a new assembly unit. Other stranded drum bodies can then operate normally. This modular design avoids the problem of machine downtime when a traditional integral stranded drum fails. The inspection or replacement of a single stranded drum body does not affect the operation of other units, significantly reducing equipment downtime. At the same time, it eliminates the need to use lifting equipment to disassemble large integral stranded drums, reducing operational difficulty, maintenance labor costs, and ensuring production continuity.

[0014] 2. When adapting to the production of different specifications of strands, the number of strand drum bodies can be flexibly combined using couplings: To increase the number of strands twisted, the new strand drum body is connected to the adjacent strand drum body via a coupling. Simultaneously, the corresponding assembly plate is inserted into the assembly slot of the bearing plate, positioned with locating pins, and fixed with bolts, thus expanding the equipment's twisting capacity. To reduce the number, the fixing bolts between the coupling and the assembly plate are removed, allowing the excess strand drum body unit to be removed. During transportation, modular components such as the strand drum body, assembly plate, and bearing bracket can be disassembled for transport. Compared to integral strand drums, the disassembled components are smaller and lighter, saving transportation space and reducing transportation costs. Furthermore, disassembled transportation reduces the risk of deformation due to component collisions, avoiding the damage issues common with traditional integral strand drums. In addition, companies do not need to equip themselves with multiple integral strand drums of different sizes; by replacing or combining strand drum body units, they can meet the needs of multi-specification production, reducing equipment procurement and storage costs and minimizing resource waste.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0022] like Figures 1 to 5 As shown, a stranding machine includes a horizontally arranged support plate 1, several linearly arrayed strand drum bodies 2, and several linearly arrayed couplings 3. The strand drum bodies 2 and couplings 3 are staggered, and every two adjacent strand drum bodies 2 are connected by a coupling 3. Several linearly arrayed assembly plates 4 are fixedly installed on the support plate 1 by bolts. The strand drum bodies 2 and assembly plates 4 correspond one-to-one. The top of each assembly plate 4 is fixedly installed with two symmetrically arranged bearing brackets 5 by bolts. The two ends of the strand drum bodies 2 are rotatably connected to the two bearing brackets 5 by bearings respectively. A corrugated hose 6 is fixedly connected to one side of the strand drum body 2. A locking ring 7 is fixedly connected to one end of the corrugated hose 6. The side of the locking ring 7 away from the corrugated hose 6 is in contact with the strand drum body 2. Several circumferentially arrayed locking bolts 8 are rotatably connected to one side of the locking ring 7. The screw parts of the locking bolts 8 are all threadedly connected to the strand drum body 2.

[0023] As an optional technical solution of this utility model, a plurality of circumferentially arrayed threaded holes 9 are provided on one side of the stranded drum body 2. The screw portions of a plurality of locking bolts 8 are all threadedly connected to the stranded drum body 2 through the threaded holes 9. The circumferentially arrayed threaded holes 9 on one side of the stranded drum body 2 provide a precise and stable threaded connection foundation for the locking bolts 8, ensuring that the locking bolts 8 can firmly connect the locking ring 7 and the stranded drum body 2, and preventing the locking ring 7 from loosening and causing the corrugated hose 6 to shift during the operation of the stranded drum body 2. At the same time, the circumferential array layout makes the locking bolts 8 evenly stressed and can fit tightly against the locking ring 7, ensuring a sealed connection between the corrugated hose 6 and the stranded drum body 2, and preventing the wire from getting stuck or worn during the twisting process.

[0024] As an optional technical solution of this utility model, the top surface of the support plate 1 is provided with a plurality of linear array assembly slots 10, and a plurality of assembly plates 4 are respectively inserted into the plurality of assembly slots 10. The thickness of the assembly plate 4 is equal to that of the assembly slot 10. The assembly slots 10 on the top surface of the support plate 1 can quickly position the installation position of the assembly plate 4, avoid lateral displacement of the assembly plate 4 during installation, ensure that the main body 2 of the stranded drum is perpendicular to the support plate 1 through the bearing bracket 5, and ensure twisting accuracy. The thickness of the assembly plate 4 is equal to that of the assembly slot 10, so that the top surface of the assembly plate 4 is flush with the top surface of the support plate 1, avoid the assembly plate 4 protruding and affecting the operation of other parts of the equipment, and at the same time enhance the connection stability between the assembly plate 4 and the support plate 1, and reduce the impact of equipment vibration on the assembly plate 4.

[0025] As an optional technical solution of this utility model, a number of symmetrically arranged positioning pins 11 are fixedly connected to the top surface of each assembly plate 4. The positioning pins 11 are all inserted into the assembly groove 10. The positioning pins 11 on the top surface of the assembly plate 4 are inserted into the assembly groove 10, which can further limit the displacement of the assembly plate 4 and prevent the assembly plate 4 from rotating or shifting due to vibration during equipment operation, thus ensuring that the relative position of the bearing bracket 5 and the strand drum body 2 is fixed. The positioning pins 11 can also help the assembly plate 4 to quickly align with the assembly groove 10, reduce the adjustment time during assembly, improve the installation efficiency of the assembly plate 4, and provide a positioning reference for subsequent disassembly and replacement of the assembly plate 4.

[0026] As an optional technical solution of this utility model, a protective frame 12 is fixedly installed on the top surface of each assembly plate 4 by bolts. The main body 2 of the stranded drum is located inside the protective frame 12, which is located between two bearing frames 5. The protective frame 12 on the top surface of the assembly plate 4 encloses the main body 2 of the stranded drum, which can prevent the wire from breaking and popping out or foreign objects from entering the main body 2 of the stranded drum during twisting, thus ensuring the safety of operators and the stable operation of equipment. The protective frame 12 is located between two bearing frames 5, which does not affect the rotation of the main body 2 of the stranded drum or the supporting function of the bearing frames 5. At the same time, it can also be used as an auxiliary gripper during maintenance, which facilitates the maintenance operation of the main body 2 of the stranded drum.

[0027] As an optional technical solution of this utility model, the left and right ends of the protective frame 12 are fixedly connected to the support frame 13, and the bottom of each support frame 13 is fixedly connected to a clamping plate 14. The two clamping plates 14 are respectively inserted into the top of the two bearing frames 5. The clamping plates 14 at the bottom of the support frames 13 at both ends of the protective frame 12 are inserted into the top of the bearing frames 5, which can enhance the installation stability of the protective frame 12 and prevent the protective frame 12 from shaking or tipping over when the equipment vibrates. The clamping structure does not require additional fasteners. When it is necessary to disassemble the protective frame 12, it is only necessary to pull the protective frame 12 upward to make the clamping plate 14 detach from the bearing frame 5, which takes into account both the fixing effect and the convenience of disassembly and assembly, and does not affect the maintenance efficiency of the strand drum body 2.

[0028] A twisting machine, the working principle of which is as follows:

[0029] 1): First, loosen the locking bolt 8 on one side of the locking ring 7 so that the screw part of the locking bolt 8 is disengaged from the threaded hole 9 of the coil drum body 2, and remove the locking ring 7 and the corrugated hose 6.

[0030] 2): Remove the connecting bolts between the assembly plate 4 and the bearing plate 1, and take the assembly plate 4, along with the bearing bracket 5 on top and the main body 2 of the stranded drum, out of the assembly slot 10.

[0031] 3): This modular design avoids the problem of the entire machine stopping when the traditional integral strand drum fails. The maintenance or replacement of a single strand drum body 2 does not affect the operation of other units.

[0032] In summary, when a malfunction occurs in the internal roller of a stranding drum body 2, the entire structure does not need to be disassembled: First, loosen the locking bolt 8 on one side of the locking ring 7, disengaging the threaded part of the locking bolt 8 from the threaded hole 9 of the stranding drum body 2, and remove the locking ring 7 and the corrugated hose 6; then, the connection of the coupling can be inspected. If the entire stranding drum body 2 needs to be replaced, simply remove the connecting bolts between the assembly plate 4 and the bearing plate 1, remove the assembly plate 4 along with the top bearing bracket 5 and the stranding drum body 2 from the assembly slot 10, and replace it with a new assembly unit; the other stranding drum bodies 2 can then operate normally. This modular design avoids the problem of machine downtime when a traditional integral stranded drum fails. The maintenance or replacement of a single stranded drum body 2 does not affect the operation of other units, significantly reducing equipment downtime. At the same time, it eliminates the need to use lifting equipment to disassemble large integral stranded drums, reducing operational difficulty, maintenance labor costs, and ensuring production continuity. When adapting to the production of different specifications of strands, the number of stranded drum bodies 2 can be flexibly combined through the coupling 3: when it is necessary to increase the number of strands to be twisted, the new stranded drum body 2 is connected to the adjacent stranded drum body 2 through the coupling 3, and the corresponding assembly plate 4 is inserted into the assembly slot 10 of the bearing plate 1, positioned by the positioning pin 11 and fixed with bolts, thus expanding the twisting capacity of the equipment; when it is necessary to reduce the number, the fixing bolts of the coupling 3 and the assembly plate 4 can be removed to remove the excess stranded drum body 2 unit. During transportation, modular components such as the main body 2 of the stranded drum, the assembly plate 4, and the bearing bracket 5 can be transported separately. Compared to a single-piece stranded drum, the disassembled components are smaller and lighter, saving transportation space and reducing transportation costs. Simultaneously, disassembled transportation reduces the risk of deformation due to component collisions, avoiding the damage issues common in traditional single-piece stranded drum transportation. Furthermore, companies do not need to equip themselves with multiple single-piece stranded drums of different sizes; by replacing or combining the main body 2 unit, they can meet multi-specification production needs, reducing equipment procurement and storage costs and minimizing resource waste.
