Description
Technical Field
[0001] This utility model belongs to the field of steel wire production technology, and specifically relates to a steel wire feeding device for steel wire production. Background Technology
[0002] Wire unwinding equipment in steel wire production is a core pre-processing device for subsequent steps such as wire drawing and twisting. It primarily releases coiled steel wire smoothly, at a uniform speed, and without damage, ensuring precise feeding for subsequent processes. The equipment typically consists of an unwinding frame, a tension control system, guiding components, and a detection unit. Some high-end models also integrate a PLC control system, enabling automated speed adjustment and automatic shutdown in case of malfunctions when linked with downstream production lines. Its core advantages lie in ensuring stable wire speed and uniform tension during the unwinding process, reducing surface scratches and stress damage. It is compatible with steel wires of different diameters from φ0.1mm to φ20mm and is widely used in the production of prestressed steel wire, spring steel wire, and steel wire rope. It is a key piece of equipment for improving the precision and production efficiency of steel wire products.
[0003] Announcement No. "CN221987790U" discloses a wire feeding device for steel wire. It includes a main frame, on which a ceramic wire guide die is mounted. A drive motor is fixedly connected to one end of the ceramic wire guide die. A bracket is fixedly connected to the main frame, and a protective structure is provided on the main frame. A guide structure is provided on the bracket. When the device is used for wire feeding, as the wire feeds periodically across the ceramic wire guide die, an electric telescopic rod is activated to move the ceramic wire guide die, keeping the wire at the feeding point as straight as possible. This reduces friction between the wire and the device during feeding, thus reducing wear and tear on the device caused by this friction.
[0004] Although the above-mentioned utility model reduces the friction between the wire and the device during wire feeding and reduces the wear and tear on the device caused by the friction between the wire and the wire, it cannot directly replace the ceramic wire feeding die with the pre-wound wire after the wire on the ceramic wire feeding die is used up. It is necessary to stop the machine and manually rewound the wire to the empty ceramic wire feeding die, which greatly prolongs the downtime, reduces production efficiency, and easily disrupts the production rhythm. Moreover, when manually winding the wire, it is difficult to ensure the uniformity of winding force and density, which can easily lead to messy wire arrangement. This can easily cause tension fluctuations during subsequent wire feeding and affect the processing accuracy of the wire. Utility Model Content
[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a wire feeding device for steel wire production, so as to solve the problem that when the steel wire on the ceramic wire feeding die is used up, it is impossible to directly replace the ceramic wire feeding die with the pre-wound steel wire. It is necessary to stop the machine and manually rewound the steel wire to the empty ceramic wire feeding die, which greatly prolongs the downtime, reduces production efficiency, and easily disrupts the production rhythm. Moreover, when manually winding the steel wire, it is difficult to ensure the uniformity of winding force and density, which easily leads to the steel wire being arranged in a messy manner. This can easily cause tension fluctuations during subsequent wire feeding, affecting the processing accuracy of the steel wire.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A wire feeding device for steel wire production includes a main frame, a motor frame fixedly connected to one side of the main frame, a first synchronous pulley and a second synchronous pulley rotatably connected to one side of the main frame, a drive motor mounted on the top of the motor frame, the output end of the drive motor fixedly connected to the second synchronous pulley, a synchronous belt installed between the first synchronous pulley and the second synchronous pulley, a connecting shaft fixedly connected to one side of the first synchronous pulley, the other end of the connecting shaft extending into the main frame and fixedly connected to a rotating disk, an assembly block fixedly connected to one side of the rotating disk, a feeding roller provided inside the main frame, an assembly groove opened at one end of the feeding roller, the assembly block and the assembly groove being inserted into each other, positioning components installed on both sides of the assembly block, and an installation component installed on the other side of the main frame;
[0008] The mounting components include a fixed post, threaded hole, threaded rod, knob, mounting plate, and cross block. A fixed post is fixedly connected to one side of the main frame. One end of the fixed post has a threaded hole, and a threaded rod is threaded into the threaded hole. One end of the threaded rod extends into the main frame and is rotatably connected to the mounting plate. The other end of the threaded rod is fixedly connected to a knob. A cross block is fixedly connected to the other side of the mounting plate. One end of the feed roller has a cross groove. The cross block and the cross groove are interlocked. This allows for direct replacement of the feed roller with pre-wound wire, eliminating the need for manual rewinding and significantly improving production efficiency. It can significantly reduce equipment downtime and effectively improve the overall operating efficiency of the production line. Moreover, it avoids the problems that can easily occur with manual wire winding, such as uneven operating force and winding angle deviation, resulting in messy and locally stacked wires on the feed roller. This can lead to sudden tension changes during subsequent wire feeding, causing scratches and tensile deformation on the wire surface.
[0009] As a preferred technical solution, the positioning component includes an internal hole, a first return spring, and a positioning post. Internal holes are provided on both sides of the assembly block. The first return spring is fixedly connected to the bottom of the internal hole, and the positioning post is fixedly connected to the other end of the first return spring. The positioning post is slidably connected to the inside of the internal hole. The other end of the positioning post extends outward from the outside of the assembly block and is arc-shaped. Positioning holes are provided on both sides of the assembly groove. The positioning post and the positioning holes are snap-fitted together, ensuring installation accuracy and guaranteeing the coaxiality of the wire feeding. This quickly limits the radial and circumferential displacement of the wire feeding roller, avoiding lateral offset. Furthermore, the cross block embedded in the cross groove further fixes the circumferential angle of the wire feeding roller, ensuring that the wire feeding roller is completely coaxial with the rotating disk and the mounting disk. Precise positioning prevents eccentric wobbling of the wire feeding roller during high-speed rotation, avoiding subsequent wire feeding tension fluctuations and ensuring the accuracy of wire processing.
[0010] As a preferred technical solution, a fixed base is fixedly connected to the top of the main frame. A wire groove is opened on the top of the fixed base. A movable base is symmetrically slidably connected inside the wire groove. A guide wheel is rotatably connected inside the movable base. A wire guide tube is embedded and fixed on one side of the wire groove. The other end of the wire guide tube extends out of the outside of the fixed base. An assembly column is embedded and fixedly connected to both sides of the wire groove. An installation hole is opened at one end of the assembly column. A second return spring is fixedly connected to the bottom of the installation hole. A movable column is fixedly connected to the other end of the second return spring. The movable column is slidably connected to the installation hole. The other end of the movable column is fixedly connected to the movable base.
[0011] In summary, the present invention has the following main advantages:
[0012] First, in this utility model, the wire feeding roller is combined with one side of the rotating disk inside the main frame, so that the assembly block on the rotating disk is inserted into the assembly groove on one side of the wire feeding roller. Then, the knob is turned to control the threaded rod to rotate. The threaded rod is threadedly connected to the threaded hole, thereby controlling the threaded rod to move forward. At the same time, the threaded rod drives the mounting disk to move forward, so that the mounting disk and one end of the wire feeding roller are combined. The cross block on one side of the mounting disk is inserted into the cross groove of the wire feeding roller. The wire feeding roller with the wire already wound can be directly replaced, eliminating the step of manual rewinding. This greatly improves production efficiency, significantly reduces equipment downtime, effectively improves the overall operating efficiency of the production line, and avoids the problem that manual winding is prone to uneven operation force and winding angle deviation, which can cause the wire to be arranged messily and locally piled on the wire feeding roller. This can easily cause sudden tension changes during subsequent wire feeding, resulting in scratches and tensile deformation on the surface of the wire.
[0013] Secondly, in this utility model, the pay-off roller is combined with one side of the rotating disk inside the main frame, so that the assembly block on the rotating disk is inserted into the assembly groove on one side of the pay-off roller. During the insertion process, the extrusion force is applied to the arc-shaped end of the positioning column, causing the positioning column to slide inside the built-in hole. The positioning column presses against the first return spring, and the positioning column retracts into the built-in hole. When the positioning column moves to the positioning hole, the first return spring resets, and the positioning column pops out and engages with the positioning hole. This ensures installation accuracy, guarantees the coaxiality of the pay-off, and can quickly limit the radial and circumferential displacement of the pay-off roller, avoiding lateral offset. Moreover, the cross block embedded in the cross groove further fixes the circumferential angle of the pay-off roller, ensuring that the pay-off roller, rotating disk, and mounting disk are completely coaxial. Precise positioning can prevent the pay-off roller from eccentric wobbling when rotating at high speed, avoid subsequent tension fluctuations in pay-off, and ensure the accuracy of wire processing.

[0021] Example
[0022] refer to Figures 1 to 5 The steel wire feeding device for steel wire production described in this embodiment includes a main frame 1. A motor frame 3 is fixedly connected to one side of the main frame 1. A first synchronous pulley 5 and a second synchronous pulley 6 are rotatably connected to one side of the main frame 1. A drive motor 4 is installed on the top of the motor frame 3. The output end of the drive motor 4 is fixedly connected to the second synchronous pulley 6. A synchronous belt 7 is installed between the first synchronous pulley 5 and the second synchronous pulley 6. A connecting shaft 8 is fixedly connected to one side of the first synchronous pulley 5. The other end of the connecting shaft 8 extends into the main frame 1 and is fixedly connected to a rotating disk 9. An assembly block 10 is fixedly connected to one side of the rotating disk 9. A feeding roller 2 is provided inside the main frame 1. An assembly groove 11 is opened at one end of the feeding roller 2. The assembly block 10 is inserted into the assembly groove 11. Positioning components 12 are installed on both sides of the assembly block 10. An installation component 14 is installed on the other side of the main frame 1.
[0023] Mounting assembly 14 includes a fixing post 141, a threaded hole 142, a threaded rod 143, a knob 144, a mounting plate 145, and a cross block 146. The fixing post 141 is fixedly connected to one side of the main frame 1. One end of the fixing post 141 has a threaded hole 142, and the threaded rod 143 is threaded into the threaded hole 142. One end of the threaded rod 143 extends into the main frame 1 and is rotatably connected to the mounting plate 145. The other end of the threaded rod 143 is fixedly connected to the knob 144. The other side of the mounting plate 145 is fixedly connected to the cross block 146. A cross groove 15 is formed at one end of the pay-off roller 2. The cross block 146 and the cross groove 15 are inserted together. The wire feeding roller 2 is merged with one side of the rotating disk 9 inside the main frame 1, so that the assembly block 10 on the rotating disk 9 is inserted into the assembly groove 11 on one side of the wire feeding roller 2. Then, the knob 144 is turned to control the threaded rod 143 to rotate. The threaded rod 143 is threadedly connected to the threaded hole 142, thereby controlling the threaded rod 143 to move forward. At the same time, the threaded rod 143 drives the mounting plate 145 to move forward, so that the mounting plate 145 is merged with one end of the wire feeding roller 2. The cross block 146 on one side of the mounting plate 145 is inserted into the cross groove 15 of the wire feeding roller 2.
[0024] refer to Figure 3The positioning component 12 includes an internal hole 121, a first return spring 122, and a positioning post 123. Internal holes 121 are provided on both sides of the assembly block 10. The first return spring 122 is fixedly connected to the bottom of the internal hole 121, and the positioning post 123 is fixedly connected to the other end of the first return spring 122. The positioning post 123 is slidably connected to the internal hole 121. The other end of the positioning post 123 extends outward from the outside of the assembly block 10 and is arc-shaped. Positioning holes 13 are provided on both sides of the assembly groove 11. The positioning post 123 is engaged with the positioning hole 13. The wire roller 2 merges with one side of the rotating disk 9 inside the main frame 1, so that the assembly block 10 on the rotating disk 9 is inserted into the assembly groove 11 on one side of the wire feeding roller 2. During the insertion process, the squeezing force is applied to the arc-shaped end of the positioning post 123, so that the positioning post 123 slides inside the built-in hole 121. The positioning post 123 presses against the first return spring 122, and the positioning post 123 retracts into the built-in hole 121. When the positioning post 123 moves to the positioning hole 13, the first return spring 122 resets, and the positioning post 123 pops out and engages with the positioning hole 13.
[0025] refer to Figures 5 to 6 A fixed base 16 is fixedly connected to the top of the main frame 1. A wire groove 17 is opened on the top of the fixed base 16. A movable base 22 is symmetrically slidably connected inside the wire groove 17. A guide wheel 23 is rotatably connected inside the movable base 22. A wire guide tube 24 is embedded and fixedly fixed on one side of the wire groove 17. The other end of the wire guide tube 24 extends out of the outside of the fixed base 16. An assembly column 18 is embedded and fixedly connected on both sides of the wire groove 17. An installation hole 19 is opened at one end of the assembly column 18. A second return spring 20 is fixedly connected to the bottom of the installation hole 19. A movable column 21 is fixedly connected to the other end of the second return spring 20. The movable column 21 is slidably connected to the installation hole 19. The other end of the movable column 21 is fixedly connected to the movable base 22. The steel wire first passes through the wire guide tube 24 of the fixed base 16 and enters the wire groove 17, contacts the guide wheels 23 on both sides, and pushes the movable base 22, so that the movable column 21 compresses the second return spring 20 in the installation hole 19. The second return spring 20 rebounds and applies force, causing the guide wheel 23 to adhere to the steel wire and rotate with the steel wire, thus achieving stable guidance of the steel wire.
[0026] Operating principle and advantages: First, push the wire feeding roller 2 into the main frame 1, so that the assembly block 10 on the rotating disk 9 is aligned with the assembly groove 11 of the wire feeding roller 2 and inserted. During the insertion process, the inner wall of the assembly groove 11 presses the arc-shaped end of the positioning post 123, causing it to compress the first return spring 122 in the built-in hole 121 and retract; after the assembly block 10 is fully inserted, the positioning post 123 pops out under the rebound action of the first return spring 122 and is locked into the positioning hole 13 of the assembly groove 11, completing the initial fixation. Then, rotating knob 144 drives threaded rod 143 forward along threaded hole 142 of fixed column 141, pushing mounting plate 145 closer to pay roller 2 until cross block 146 inserts into cross groove 15 of pay roller 2, achieving stable installation of pay roller 2. Then, drive motor 4 on motor frame 3 is started, its output end drives second synchronous wheel 6 to rotate, which is transmitted to first synchronous wheel 5 through synchronous belt 7, thereby causing connecting shaft 8 to drive rotating disk 9 to rotate, and finally driving pay roller 2 to rotate synchronously to release steel wire. The steel wire released by pay roller 2 first passes through wire tube 24 of fixed seat 16 and enters wire groove 17, contacts guide wheels 23 on both sides and pushes moving seat 22, causing moving column 21 to compress second return spring 20 in mounting hole 19 of mounting column 18. Second return spring 20 rebounds and applies force, allowing guide wheel 23 to fit tightly against steel wire and rotate synchronously with steel wire, maintaining stable steel wire delivery throughout the process and completing pay roller operation;
[0027] This invention allows for the direct replacement of the wire feeding roller 2 with the pre-wound steel wire, eliminating the need for manual rewinding and significantly improving production efficiency. It also reduces equipment downtime and improves the overall operating efficiency of the production line. Furthermore, it avoids the problems that arise from uneven operating force and winding angle deviations during manual wire winding, which can lead to messy and locally stacked steel wires on the wire feeding roller 2. This can cause sudden tension changes during subsequent wire feeding, resulting in scratches and tensile deformation on the steel wire surface.
