Description

Technical Field

[0001] This utility model relates to the field of stranding machine technology, and in particular to a modular stranding machine with a quick-change strand cage. Background Technology

[0002] A stranding machine (also known as a wire bundling machine or wire harnessing machine) is a specialized industrial piece of equipment used to spirally wind two or more wires (such as metal wires, copper wires, aluminum wires, optical fibers, enameled wires, steel wires, etc.) together according to a specific pattern to form a composite cable with a stable structure and superior performance. It is widely used in fields such as wire and cable, electronics, communications, power, automotive, aerospace, and medical devices, and is one of the core pieces of equipment in the cable manufacturing process.

[0003] Patent publication number CN216623885U specifically relates to a cage-type stranding machine, which includes a frame, a stranding cage rotatably mounted on the frame, and a take-up seat. Multiple pay-off frames and spools are rotatably mounted on the stranding cage. The spools are located inside the pay-off frames, and guide wires on the spools extend from the spools and pass through the take-up seat. The spools are rotatably mounted inside the pay-off frames. A driving component for driving the spools to rotate is provided on the outer side of the sidewall of the pay-off frames. Connecting shafts are provided at both ends of the spools along their axial direction. An elastic connecting component is provided between the connecting shafts and the output end of the driving component, and the connecting component is used to connect the connecting shafts of the spools to the output end of the driving component. Although the aforementioned patents improve the consistency of strand tension and thus enhance the quality of stranded wire by reducing the difference in wire feeding speed between multiple reels, the overall structure of the winding cage is still problematic. The wire feeding frame is fixedly connected to the winding cage body, lacking modular design. Therefore, when different guide structures or wire feeding configurations need to be replaced or adjusted, the entire winding cage must be disassembled or modified. This process is complex, time-consuming, and inconvenient for quickly switching production tasks, reducing the equipment's adaptability to different stranding specifications.

[0004] Therefore, a modular stranding machine with a quick-change coil is needed. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents, which have an integral structure with the wire feeding frame fixedly connected to the wire feeding frame and lacking modular design, the entire wire feeding frame must be disassembled or modified when different specifications of guide structure or adjustments to wire feeding configuration are required. This is complicated, time-consuming, and not convenient for quick switching of production tasks, thus reducing the equipment's adaptability to different stranding specifications. This utility model provides a modular stranding machine with a quick-change wire feeding frame.

[0006] The technical solution is as follows: A modular stranding machine with a quick-change coil, comprising a base, a guide seat, a rotating frame, a motor, a feed wheel, a limit rod, and a guide plate. The guide seat is installed on the left side of the base, and the rotating frame is rotatably mounted on the right side of the base. The motor's output shaft is connected to the rotating frame via a coupling. Multiple limit rods are fixedly connected to the rotating frame, and feed wheels are sleeved on the limit rods. A guide plate is slidably mounted on the left side of the rotating frame. The machine also includes a fixed plate, a sliding rod, an insert rod, and an elastic element. Multiple fixed plates are fixedly connected to the rotating frame, and a sliding rod is slidably mounted on the fixed plate. An insert rod is fixedly connected to one end of the sliding rod near the guide plate and is inserted into a positioning hole in the rotating frame. An elastic element is sleeved on the sliding rod, and both ends of the elastic element are connected to the fixed plate and the insert rod, respectively.

[0007] Furthermore, it also includes an airbag, a connecting pipe, an air tank, and an air pump. An airbag is provided on the surface of the limiting rod. The airbag is connected to and connected to the connecting pipe near the rotating frame. Multiple air tanks are installed on the rotating frame. An air pump is installed on the left side of the air tank. The other end of the connecting pipe is connected to the air pump.

[0008] Furthermore, it also includes a guide cylinder, which is installed on the guide seat.

[0009] Furthermore, it also includes a protective pad, with a protective pad installed on the inner wall of the guide cylinder.

[0010] Furthermore, it also includes two mounting holes on both the left and right sides of the base.

[0011] Furthermore, it also includes a pull ring, with a pull ring provided on the slide bar.

[0012] Compared with the prior art, this utility model provides a modular stranding machine with quick-change winding cage, which has the following beneficial effects: 1. By pulling the slide bar outward again, the insertion rod is removed from the positioning hole of the guide plate, and the locking state is released. Then the guide plate can be slid out to the left from the rotating frame to achieve quick disassembly, thereby improving the equipment's adaptability to different stranding specifications and facilitating quick switching of production tasks.

[0013] 2. By starting the air pump, the compressed gas in the air tank is pumped directly into the air bag through the connecting pipe. After the air bag is filled with gas, it expands rapidly and tightly adheres to and presses against the inner wall of the pay-off reel from the radial direction. The huge static friction force generated effectively prevents the pay-off reel from axial movement or circumferential loosening during high-speed operation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: A modular stranding machine with a quick-change coil, please refer to [link / reference]. Figures 1-5The system includes a base 1, a guide seat 2, a rotating frame 3, a motor 4, a wire feeding wheel 5, a limiting rod 6, and a guide plate 7. The guide seat 2 is installed on the left side of the base 1, and the rotating frame 3 is rotatably mounted on the right side of the base 1. The motor 4 is installed on the right side of the base 1, and the output shaft of the motor 4 is connected to the rotating frame 3 via a coupling. Several limiting rods 6 are fixedly connected to the rotating frame 3, and the wire feeding wheel 5 is sleeved on the limiting rods 6. The guide plate 7 is slidably mounted on the left side of the rotating frame 3. The system also includes a fixed plate 8, a sliding rod 9, an insert rod 10, and an elastic element 11. Several fixed plates 8 are fixedly connected to the rotating frame 3, and sliding rods 9 are slidably mounted on the fixed plates 8. The end of the sliding rod 9 near the guide plate 7 is fixed. A fixed connection is provided with a plug rod 10, which is inserted into the positioning hole of the rotating frame 3. An elastic element 11 is sleeved on the slide rod 9, and the two ends of the elastic element 11 are connected to the fixed plate 8 and the plug rod 10 respectively. A guide cylinder 16 is installed on the guide seat 2 to guide the twisted wire. A protective pad 17 is provided on the inner wall of the guide cylinder 16 to effectively prevent the surface of the wire from being scratched when it is led out. Two mounting holes 18 are opened on the left and right sides of the base 1 to securely install the whole machine on the ground or platform with bolts to ensure the stability and vibration reduction effect of the equipment under high-speed operation. A pull ring 19 is provided on the slide rod 9 to increase the force point between the hand and the slide rod 9, thereby making it easier to pull the slide rod 9.

[0022] When using a modular stranding machine, first, place the wire-loaded reel 5 onto the limiting rod 6 on the rotating frame 3, ensuring it can rotate freely on the limiting rod 6 for smooth wire feeding. Then, install the guide plate 7. First, pull the sliding rod 9 outwards, causing the insertion rod 10 to move outwards against the elastic force of the elastic element 11, reserving space for the installation of the guide plate 7. Next, slide the guide plate 7 from the left side to the corresponding position on the left side of the rotating frame 3 until it is fully in place. At this point, release the sliding rod 9; the insertion rod 10 will automatically pop inwards under the restoring force of the elastic element 11, inserting into the positioning hole on the side wall of the guide plate 7, thus achieving quick locking and axial fixation of the guide plate 7. After installation, the wire ends from each pay-off wheel 5 are passed through the guide plate 7 and enter the twisting area. The motor 4 is started, and the motor 4 drives the rotating frame 3 to rotate at high speed through the coupling, which drives the pay-off wheel 5 and the guide plate 7 to rotate synchronously. This allows multiple wires to be evenly twisted along a predetermined trajectory under the guidance of the guide plate 7, completing the cable twisting process. When it is necessary to replace or disassemble the guide plate 7, simply pull the slide bar 9 outward again to make the insertion rod 10 exit from the positioning hole of the guide plate 7 and release the locking state. Then, the guide plate 7 can be slid off the rotating frame 3 to the left to achieve quick disassembly, thereby improving the equipment's adaptability to different twisting specifications and facilitating quick switching of production tasks.

[0023] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 4It also includes an airbag 12, a connecting pipe 13, an air tank 14 and an air pump 15. An airbag 12 is provided on the surface of the limiting rod 6. The airbag 12 is connected to and communicates with the connecting pipe 13 near the rotating frame 3. Multiple air tanks 14 are installed on the rotating frame 3. An air pump 15 is installed on the left side of the air tank 14. The other end of the connecting pipe 13 is connected to the air pump 15.

[0024] After the pay-off reel 5 is fitted onto the limiting rod 6, the air pump 15 is started. The air pump 15 pumps the compressed gas in the air tank 14 directly into the air bag 12 through the connecting pipe 13. After the air bag 12 is filled with gas, it expands rapidly and tightly adheres to and presses against the inner wall of the pay-off reel 5 from the radial direction. The huge static friction generated effectively prevents the pay-off reel 5 from axial movement or circumferential loosening during high-speed operation. When the pay-off reel 5 needs to be replaced, the air pump 15 is turned off and the air bag 12 is vented. After the air bag 12 contracts, it separates from the inner wall of the pay-off reel 5 and loses its constraint. At this time, the pay-off reel 5 can be easily removed from the limiting rod 6 or replaced.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
