Description

Technical Field

[0001] This invention relates to the field of winding mechanism technology, specifically to a wire traction winding mechanism. Background Technology

[0002] In industries such as power transmission, communication engineering, industrial automation production lines, and cable processing, the pulling and winding of conductors is a core process that runs through the entire production and construction process. Its operational quality and efficiency directly determine the qualification rate of cable products, the progress of engineering construction, and the level of safe production. As the industry's requirements for cable transmission stability, construction precision, and production scale continue to increase, traditional conductor pulling and winding mechanisms have gradually exposed many technical shortcomings and are no longer suitable for the current high-requirement application scenarios.

[0003] However, existing winding mechanisms require aligning bolt holes one by one and repeatedly tightening bolts during use, which is cumbersome and time-consuming. When bolts rust after long-term use, disassembly becomes much more difficult, and cutting tools may be needed to forcibly separate them, making it difficult to disassemble the mounting roller. Summary of the Invention

[0004] The purpose of this invention is to provide a wire traction and winding mechanism. By setting up an installation part, it solves the problem that existing winding mechanisms require aligning bolt holes one by one and repeatedly tightening bolts during use, which is cumbersome and time-consuming. When bolts rust after long-term use, the difficulty of disassembly increases significantly, and even cutting tools are needed to forcibly separate them, making it difficult to disassemble the installation roller.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a wire traction and winding mechanism, comprising a fixed plate, and further comprising: a mounting part mounted on the fixed plate; a fixing part disposed on the mounting part; a guide part mounted on the fixed plate; the mounting part including a limiting component mounted on the fixed plate; and a rotating component disposed on the fixed plate; the limiting component including a mounting roller disposed within the fixed plate, the front side of the mounting roller extending outside the fixed plate; a rotating shaft rotatably connected to the fixed plate; a connecting rod fixedly connected to the inner wall of the rotating shaft; and a semi-circular block fixedly connected to the front side of the connecting rod. A semicircular block two is slidably connected to the outer wall of the connecting rod. A fixing plate two is fixedly connected to the rear side of the semicircular block two. A spring one is sleeved on the outer wall of the connecting rod. The front side of the spring one is fixedly connected to the fixing plate two, and the rear side of the spring one is fixedly connected to the rotating shaft.

The initial state of the spring two is a compressed state.

[0006] Furthermore, the fixing part includes a winding assembly mounted on the limiting assembly; and two spreading assemblies, both of which are mounted on the winding assembly, with the fixing part located on the outer wall of the mounting roller.

[0007] Furthermore, the guide portion includes a reciprocating assembly disposed on a fixed plate; and a locking assembly mounted on the reciprocating assembly, wherein the guide portion is higher than the fixed portion.

[0008] Furthermore, the rotating assembly includes several limiting grooves formed on the rotating shaft, several limiting blocks 2 are fixedly connected to the outer wall of the mounting roller, and the several limiting blocks 2 are respectively adapted to the several limiting grooves. A motor bracket 1 is fixedly connected to the rear side of the fixing plate 1, and a motor is fixedly connected to the inner wall of the motor bracket 1. The output shaft of the motor is fixedly connected to the rotating shaft through a coupling. A rotating ring 1 is rotatably connected to the outer wall of the mounting roller, and a rotating ring 2 is slidably connected to the outer wall of the limiting groove. A spring 3 is sleeved on the outer wall of the mounting roller. The rear side of the spring 3 is fixedly connected to the rotating ring 2, and the front side of the spring 3 is fixedly connected to the rotating ring 1. The motor bracket 1 is fixed to the fixing plate 1 through the motor.

[0009] Furthermore, the winding assembly includes a rotating roller sleeved on the outer wall of the mounting roller. Two baffles are fixedly connected to the outer wall of the rotating roller. Two friction rings are provided on the inner wall of the rotating roller, and two friction rings are provided on the outer wall of the mounting roller. The side of the friction rings that contacts the rotating roller is sanded, and the side of the friction rings that contacts the mounting roller is sanded.

[0010] Furthermore, the spreading assembly includes a compression ring 1 disposed between friction ring 1 and friction ring 2. A threaded rod is rotatably connected to the front side of the compression ring 1. Two sliding rods 2 are fixedly connected to the front side of the compression ring 1. A compression ring is disposed between friction ring 1 and friction ring 2. The threaded rod passes through the compression ring and is threadedly connected to the compression ring. Both sliding rods 2 pass through the compression ring. The surfaces of compression ring 1, the compression ring, friction ring 1, and friction ring 2 that are in contact are all inclined surfaces.

[0011] Furthermore, the reciprocating assembly includes a reciprocating lead screw rotatably connected to the inner wall of a fixed plate. The front side of the reciprocating lead screw extends to the outside of the fixed plate. A motor bracket two is fixedly connected to the front side of the fixed plate. A motor two is fixedly connected to the inner wall of the motor bracket two. The output shaft of the motor two is fixedly connected to the reciprocating lead screw via a coupling. A sliding block is slidably connected to the outer wall of the reciprocating lead screw. The motor two is fixed to the fixed plate through the motor bracket two. The slider on the sliding block is slidably connected to the threaded groove on the reciprocating lead screw.

[0012] Furthermore, the positioning assembly includes two positioning plates fixedly connected to the outer wall of the sliding block, and a rope is provided on the outer wall of the rotating roller. The rope is wound around the rotating roller, and the end of the rope extends between the two positioning plates. The distance between the positioning plates is adapted to the size of the rope.

[0013] The present invention has the following beneficial effects: 1. In this invention, the mounting roller is first inserted into the fixing plate 1 for pre-positioning via the mounting part. After the fixing part is installed, the mounting roller is pushed towards the rotating shaft. During the pushing process, the limiting block 2 is precisely aligned and fitted. As the insertion action is performed, the rotating ring 2 fits against the fixing plate 1, and the spring 3 is compressed to generate a pre-tightening force. When the semicircular block 1 contacts the limiting block 1, the inclined structure of the semicircular block 1 pushes the limiting block 1 to expand to both sides, and the spring 2 is simultaneously compressed. After the semicircular block 1 has completely passed the limiting block 1, the spring 2 elastically resets, driving the limiting block 1 to engage in the limiting groove of the semicircular block 1, thus completing the locking and fixing of the mounting roller. Disassembly stage: Push the mounting roller backward, causing the limiting block 1 to move backward synchronously and contact the semicircular block 2. The inclined structure of the semicircular block 2 squeezes the limiting block 1 again, causing it to expand. After the limiting block 1 passes the semicircular block 2, pull the mounting roller forward. At this time, the spring 1 is stretched and generates a reverse pulling force, causing the fixing plate 2 and the semicircular block 2 to move closer to the semicircular block 1. The limiting block 1 contracts under the elastic action of the spring 2. It passes through the semicircular block 2 and the semicircular block 1 in sequence, realizing the unlocking and disassembly of the mounting roller. No auxiliary tools such as wrenches and screwdrivers are needed. Compared with the traditional bolt fixing or welding connection method, it is easier to disassemble and solves the pain points of the traditional mechanism being cumbersome to disassemble and relying on professional tools.

[0014] 2. This invention, through the fixing part, allows the mounting roller to be installed in place. By manually or with tools rotating the threaded rod, utilizing the threaded transmission principle, the threaded rod drives the matching extrusion ring one to move closer to each other axially. As the distance between them decreases, a bidirectional extrusion force is formed on the friction ring one and friction ring two located in the middle. Under this pressure, friction ring one expands outward, and friction ring two contracts inward. Finally, the outer surface of friction ring one is tightly fitted with the inner wall of the rotating roller, and the inner surface of friction ring two is tightly fitted with the outer wall of the mounting roller. Through the static friction force generated between the friction rings and the contact surfaces of the two rollers, the rotating roller and the mounting roller are coaxially fixed, completing a stable assembly, avoiding relative slippage between the rotating roller and the mounting roller, ensuring the synchronization and transmission accuracy of traction winding, and improving the winding quality of the conductor.

[0015] 3. After the guide and fixing parts are installed, the rope is first passed through the guide channel of the clamping plate and then wound around the surface of the rotating roller that is fixed on the mounting roller. After starting the motor and motor 2, the motor drives the mounting roller to rotate synchronously through the transmission link, thereby driving the rotating roller to rotate. The friction between the rotating roller and the rope is used to complete the rope winding operation. At the same time, motor 2 drives the reciprocating screw to rotate. Since the sliding block and the reciprocating screw are threadedly engaged, and the downward pressure generated when the rope passes through the clamping plate, the tendency of the sliding block to rotate synchronously with the reciprocating screw is restricted, so that the sliding block can only make reciprocating linear motion along the axial direction of the reciprocating screw, thereby driving the clamping plate to slide synchronously back and forth. During the sliding process, the clamping plate forms a lateral guide for the rope, guiding the rope being wound evenly to different axial positions of the rotating roller, and finally realizing the orderly winding of the rope along the surface of the rotating roller, effectively reducing transportation and storage costs, while avoiding wear or structural deformation caused by interlayer compression of the rope.

The front side of the reciprocating lead screw 411 extends to the outside of fixed plate 111. A motor bracket 2 412 is fixedly connected to the front side of fixed plate 111. A motor 2 413 is fixedly connected to the inner wall of motor bracket 2 412. The output shaft of motor 2 413 is fixedly connected to the reciprocating lead screw 411 via a coupling.

[0024] It should be noted that the control of motor 224 and motor 413 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0025] In use, first insert the mounting roller 211 into the fixing plate 111. After insertion, put the fixing part 3 onto the mounting roller 211. Then, insert the mounting roller 211 into the rotating shaft 212. During insertion, align the limiting block 222 with the fixing block 222 and make them fit. As insertion proceeds, the rotating ring 226 will contact the fixing plate 111. With continued insertion, the spring 327 will be compressed to a certain extent. Then, the semicircular block 214 will contact the limiting block 219, and the semicircular block 214 will push the limiting block 219 to both sides. As it pushes, the spring 2110 will be compressed to a certain extent. With compression, the semicircular block 214 can pass through the limiting block 219 and then be stopped. Block 1 219 will lock semicircular block 1 214 to prevent it from falling off, thus achieving the effect of installing the mounting roller 211. When it needs to be removed, push the mounting roller 211 backward. At this time, the limiting block 1 219 will continue to move backward. As it moves, the limiting block 1 219 will come into contact with semicircular block 2 215. Upon contact, the limiting block 1 219 will be squeezed again. After the limiting block 1 219 passes semicircular block 2 215, it will pull the mounting roller 211 forward. At this time, the limiting block 1 219 will bring semicircular block 2 215 and fixing plate 2 216 closer to semicircular block 1 214. During the movement, spring 1 217 will be stretched to a certain extent. When semicircular block 2 215 and semicircular block 1 214 come into contact... After contact, pull the mounting roller 211. At this time, the limiting block 219 will retract again through the semicircular block 215 and the semicircular block 214, thereby achieving the effect of disassembling the mounting roller 211. After the mounting roller 211 is installed, rotate the threaded rod 322. At this time, the threaded rod 322 will bring the compression ring 321 and the compression ring 324 closer together. As they get closer, they will compress the friction ring 313 and the friction ring 314. As they are compressed, the friction ring 313 will expand, while the friction ring 314 will contract. As the friction ring 313 moves, it will contact the inner wall of the rotating roller 311, while the friction ring 314 will contact the outer wall of the mounting roller 211, thereby removing the roller. The rotating roller 311 is fixed on the mounting roller 211, thereby achieving a stable effect on the rotating roller 311. After the fixing part 3 is installed, the rope 422 is passed through the locking plate 421 and wound around the rotating roller 311. Then, the motor 224 and the second motor 413 are started. When the motor 224 rotates, the rope 422 will be wound up through the mounting roller 211 and the rotating roller 311. When the reciprocating screw 411 rotates, the sliding block 414 and the locking plate 421 will slide back and forth on the reciprocating screw 411, so that the rope 422 is evenly wound around the rotating roller 311. The downward pressure of the rope 422 on the sliding block 414 will prevent the sliding block 414 from rotating with the reciprocating screw 411.
