Description

Technical Field

[0001] This application relates to the field of galvanized iron wire processing technology, and in particular to a galvanized iron wire feeding machine. Background Technology

[0002] Against the backdrop of rapid development in modern industry, the demand for galvanized iron wire in the metal processing industry continues to rise. From steel bar binding in construction to cable reinforcement in the power and communication fields, and even to applications in people's lives such as livestock fencing and home hardware, galvanized iron wire has become an indispensable basic material due to its excellent rust resistance and mechanical strength. This has led to higher requirements for the production efficiency and processing quality of galvanized iron wire. As a key piece of equipment at the front end of production, the performance of the wire feeding machine directly affects the stability of subsequent processes and the quality of the finished product.

[0003] A search revealed Chinese patent publication number CN213011192U, which discloses a steel strand laying mechanism, including a base, a rotating seat, and limiting components. The base includes a rotating shaft, multiple support plates, and a connecting ring. The inner and outer ends of the support plates are connected to the rotating shaft and the connecting ring, respectively. Each support plate is adjustablely equipped with a supporting wheel. The supporting wheel includes a clamping plate, vertical plates on both sides of the clamping plate, and a wheel rotatably mounted between the two vertical plates. The rotating seat includes a disc, multiple support frames, and a support cylinder. The disc is rotatably mounted on the rotating shaft and contacts the wheel. Multiple vertical plates are circumferentially arranged on the connecting ring. Each vertical plate has a rotating roller rotatably mounted on one side facing the rotating shaft, and a lead ring is bolted to the vertical plate. The limiting components are detachably mounted on the upper ends of two corresponding vertical plates. This invention achieves stable operation of the laying process, is easy to disassemble and maintain, and can be well integrated with the manufacturing of anchor cables, demonstrating good practicality.

[0004] The aforementioned patent specification mentions that "the limiting component can be detachably installed on the upper end of the two corresponding upright plates. This utility model achieves stable operation of the wire laying operation, is easy to disassemble and maintain, and can be well integrated with the processing and manufacturing of anchor cables, thus possessing good practicality." While the above content facilitates disassembly and maintenance and can be well integrated with the processing and manufacturing of anchor cables, in practice, excessive tension fluctuations can cause the wire to undergo tensile deformation or even breakage during the wire laying process. Therefore, a galvanized wire laying machine is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a galvanized iron wire feeding machine, which aims to improve the problem of unstable wire feeding in some devices.

[0006] The galvanized iron wire feeding machine provided in this application adopts the following technical solution: A galvanized iron wire feeding machine includes a support plate, a feeding mechanism inside the support plate, a limit mechanism on the top of the support plate, and a tension mechanism on the top of the support plate. The feeding mechanism includes a motor, which is fixedly connected inside the support plate. A drive wheel is fixedly connected to the drive end of the motor. A support plate is rotatably connected to the outside of the motor. Four driven wheels are rotatably connected to the top of the support plate. An internal gear ring is rotatably connected to the outside of the support plate. A placement frame is fixedly connected to the top of the internal gear ring. A limiting component for placing sliding is provided on the outside of the placement frame. The above technical solution works as follows: During operation, a motor fixed inside the support plate drives the drive wheel to rotate. The drive wheel meshes with the four driven wheels on the top of the support plate, causing them to rotate synchronously. The driven wheels then mesh with the internal gear ring on the outside of the support plate, causing the internal gear ring to rotate within the support plate. This, in turn, drives the top placement frame to rotate, thus enabling the galvanized iron wire to be laid out. During the laying process, the limiting component on the outside of the placement frame uses a connecting ring and a limiting plate to radially limit a pair of wire coils, preventing them from loosening and slipping. After the iron wire is led out from the placement frame, it passes through the tension mechanism on the top of the support plate. At the same time, the limiting mechanism on the top of the support plate limits the wire, effectively solving problems such as unstable laying and uneven tension, thus improving production efficiency and wire quality.

[0007] Preferably, the tension mechanism includes a helical rod, the helical rod being fixedly connected to the outside of the support plate, and a limiting plate being fixedly connected to the outer top of the helical rod. By adopting the above technical solution, when the rotating disk moves to the position of the second limiting plate on the outer side of the top of the screw rod, the second limiting plate will restrict its continued movement, avoiding the rotating disk from running beyond its limit due to excessive tension, thus improving the wire feeding quality and the reliability of equipment operation.

[0008] Preferably, the external teeth of the driving wheel and the external teeth of the driven wheel are engaged, the internal teeth of the internal gear ring and the external teeth of the driven wheel are engaged, a connecting post is fixedly connected inside the driven wheel, and the external part of the connecting post is rotatably connected to the outside of the support plate. By adopting the above technical solution, when the motor starts, the driving wheel that is fixedly connected to it begins to rotate. The external teeth of the driving wheel mesh with the external teeth of the four driven wheels, transmitting power to the driven wheels and causing them to rotate around the connecting column on the top of the support plate. Since the external teeth of the driven wheels mesh with the internal teeth of the internal gear ring, the rotation of the driven wheels will further drive the internal gear ring to rotate inside the support plate.

[0009] Preferably, the limiting component includes a connecting ring, the outside of which is fixedly connected to the outside of the placement frame, and a plurality of limiting plates are rotatably connected to the outside of the connecting ring; By adopting the above technical solution, the upper inclined surface buffers the centrifugal force generated by the rotation of the wire roll during the wire feeding process, while the lower flat surface forms a radial constraint on the wire roll to prevent it from loosening or slipping during rotation. The limiting component, through the cooperation of the connecting ring and the limiting plate, realizes convenient installation and stable limiting of the wire roll, effectively improving the stability of the wire feeding process, reducing wire feeding failures caused by the displacement of the wire roll, and ensuring orderly wire feeding of galvanized iron wire.

[0010] Preferably, the upper outer end of the limiting plate is an inclined surface and the lower outer end is a flat surface, and the outer part of the internal toothed ring is rotatably connected to the inside of the support plate; By adopting the above technical solution, during the galvanized iron wire laying operation, the inner toothed ring rotates inside the support plate, driving the top placement frame to rotate to achieve wire laying. At this time, the limiting plate fixed to the outside of the placement frame comes into play. Its upper inclined surface design can guide the iron wire roll to slide into the positioning quickly when installing the iron wire roll, reducing the installation difficulty. After installation, the lower flat surface is in close contact with the side of the iron wire roll. When the placement frame rotates and generates centrifugal force, the planar structure forms a radial constraint on the iron wire roll, preventing it from loosening or slipping.

[0011] Preferably, the outer side of the spiral rod is provided with intersecting spiral grooves, and a rotating disk is slidably connected to the outside of the intersecting spiral grooves, and a sliding groove is opened inside the rotating disk; By adopting the above technical solution, during the wire feeding process of galvanized iron wire, when the iron wire passes through the hole of the wire insertion block inside the rotating disk and is stretched, the wire insertion block drives the sliding rod to slide in the groove of the rotating disk, so that the rotating disk is subjected to force. Since the rotating disk is sleeved on the outside of the spiral rod with cross spiral grooves, the rotating disk under force will move axially along the cross spiral grooves of the spiral rod, thereby changing the tension of the iron wire. As the wire feeding process progresses, the change in iron wire tension is fed back in real time as the displacement of the rotating disk on the spiral rod, realizing automatic tension adjustment.

[0012] Preferably, a sliding rod is slidably connected inside the slide groove, and a wire insertion block is fixedly connected to the outside of the sliding rod. The outside of the wire insertion block is slidably connected to the inside of the rotating disk, and a hole is opened inside the wire insertion block. By adopting the above technical solution, when the galvanized iron wire is laid out, the iron wire is led out through the hole inside the insertion block. When the iron wire is stretched and the tension changes, the insertion block slides inside the rotating disk due to the force, and at the same time drives the sliding rod fixedly connected to it to slide synchronously in the groove of the rotating disk. The sliding cooperation between the sliding rod and the groove allows the displacement of the insertion block to be accurately transmitted to the rotating disk, causing the rotating disk to move along the spiral rod to adjust the tension.

[0013] Preferably, the limiting mechanism includes a support block, the support block is fixedly connected to the outside of the support plate, a cylinder is fixedly connected to the inside of the support block, a push plate is fixedly connected to the driving end of the cylinder, a spring is sleeved on the outside of the outer protruding shaft of the push plate, and the other end of the spring is fixedly connected to the outside of the support block. By adopting the above technical solution, before the galvanized iron wire is unloaded, the cylinder in the limiting mechanism is activated. The cylinder's drive end pushes the push plate towards the wire roll until the push plate contacts the side of the wire roll. At this time, the spring sleeved on the protruding shaft outside the push plate is compressed, forming a buffer force. During the unloading process, if the wire roll undergoes axial displacement due to rotation, the elastic force of the spring can push the push plate to reset in time, maintaining continuous limiting of the wire roll.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. Through multi-stage transmission and bidirectional limiting mechanism, a highly efficient and stable wire feeding effect is achieved. The multi-stage gear transmission system makes the placement frame rotate smoothly with low power transmission loss, which can ensure uniform wire feeding speed and reduce the tensile deformation of the wire caused by speed fluctuation. The inclined and flat combination structure of the limiting plate can adaptively constrain the wire roll in the radial direction, which facilitates the quick installation of the wire roll, effectively prevents the wire from loosening and slipping, significantly improves wire feeding efficiency and wire quality, and reduces the frequency of manual adjustment and material loss. 2. When the wire is under stress, the coordinated sliding of the insertion block, sliding rod, and rotating disk converts the tension change into the axial displacement of the spiral rod. The transmission characteristics of the cross spiral groove automatically compensate for tension fluctuations, avoiding frequent manual intervention. The limit plate sets a safe stroke for the rotating disk, preventing structural damage due to sudden tension changes. This ensures the tension stability of the galvanized wire during the wire feeding process, reduces breakage and entanglement caused by uneven tension, and improves the reliability and service life of the equipment.

[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0017] Example: A galvanized iron wire feeding machine, referring to... Figures 1 to 3 The system includes a support plate 1, a wire feeding mechanism 2 inside the support plate 1, a limit mechanism 4 on the top of the support plate 1, the limit mechanism 4 is used to control the position of the wire coil in the axial direction to prevent deviation or shaking during wire feeding, and a tension mechanism 5 on the top of the support plate 1, the tension mechanism 5 is used to monitor and adjust the tension of the wire during wire feeding in real time to avoid wire breakage, deformation or tangling due to uneven tension. The support plate 1 is used to provide a stable mounting platform for the wire feeding mechanism 2, the limit mechanism 4 and the tension mechanism 5. The wire feeding mechanism 2 includes a motor 21, which is fixedly connected inside the support plate 1. The drive end of the motor 21 is fixedly connected to a drive wheel 22, which is used to drive the 22 to rotate. The motor 21 is rotatably connected to a support plate 24. Four driven wheels 23 are rotatably connected to the top of the support plate 24. An internal gear ring 25 is rotatably connected to the outside of the support plate 24. A placement frame 3 is fixedly connected to the top of the internal gear ring 25. A limiting component 27 for placing the sliding is provided on the outside of the placement frame 3. The limiting component 27 is used to prevent the wire roll from radially displacing or loosening and falling off when rotating at high speed. The external teeth of the driving wheel 22 and the external teeth of the driven wheel 23 are meshed and connected. The driving wheel 22 transmits the motor power to the driven wheel 23 through tooth meshing. The internal teeth of the internal gear ring 25 are meshed and connected to the external teeth of the driven wheel 23. The internal gear ring 25 adopts an internal tooth design to mesh with the driven wheel 23, which converts the rotational motion of the driven wheel 23 into its own circular motion. A connecting column 26 is fixedly connected inside the driven wheel 23. The driven wheel 23 forms a multi-stage transmission through gear meshing, which evenly distributes the power of the driving wheel to the internal gear ring 25, while reducing the speed and increasing the torque. The external part of the connecting column 26 is rotatably connected to the outside of the support plate 24. The limiting component 27 includes a connecting ring 271, which is externally fixedly connected to the outside of the placement frame 3. The placement frame 3 is used to carry the coiled galvanized iron wire. It adopts a hollow design to reduce weight and has a rust-proof coating on the surface to extend its service life. Multiple limiting plates 272 are rotatably connected to the outside of the connecting ring 271. The upper end of the limiting plate 272 is designed with a bevel for quick installation of the iron wire coil, and the lower end is flat and fits tightly against the side of the coil when the wire is laid out, limiting the radial movement of the iron wire coil. The upper end of the limiting plate 272 is beveled and the lower end is flat. The external end of the internal toothed ring 25 is rotatably connected to the inside of the support plate 1. Specifically, during operation, the built-in high-torque servo motor 21 drives the surface-hardened drive wheel 22 to rotate. The drive wheel 22 meshes with four driven wheels 23 through a locking tooth, transmitting power to the internal gear ring 25 made of alloy steel, which in turn drives the top of the placement frame 3, which has been perforated and treated for rust prevention, to rotate, thus releasing the galvanized iron wire. In the limiting component 27 outside the placement frame 3, the wear-resistant engineering plastic limiting plate 272 is installed on the placement frame 3 through the connecting ring 271. Its inclined and flat structure facilitates the installation of the wire coil and prevents radial displacement. During the wire laying process, the cylinder 42 fixed by the aluminum alloy support block 41 pushes the push plate 44 with a rubber buffer layer on its surface, which, together with the spring 43, axially limits and buffers the wire coil. At the same time, the wire passes through the hole of the wire insertion block 53 with a polished surface. When the tension changes, the wire insertion block 53 drives the sliding rod 54 to slide in the groove 55 of the rotating disk 52, causing the rotating disk 52 to move along the spiral rod 51 with cross spiral grooves, realizing automatic tension adjustment. The second limiting plate 56 limits the movement range of the rotating disk 52 to prevent over-limit. All components of the whole set of equipment work together to achieve a stable, efficient and accurate wire laying process for galvanized iron wire.

[0018] Reference Figure 1 , Figure 4 and Figure 5 The tension mechanism 5 includes a spiral rod 51, which is fixedly connected to the outside of the support plate 1. A limit plate 56 is fixedly connected to the top outer side of the spiral rod 51. The limit plate 56 is used to limit the maximum range of movement of the rotating plate 52 and prevent it from detaching from the spiral rod 51. The spiral rod 51 has a cross spiral groove on its outer side. The spiral rod 51 has a cross spiral groove on its surface, which serves as a guide track for the movement of the rotating plate 52. The change in wire tension is converted into the axial displacement of the rotating plate 52 through the spiral transmission principle. The rotating plate 52 is slidably connected to the outside of the cross spiral groove. The rotating plate 52 slides along the axial direction of the spiral rod 51 when the wire tension changes through the cooperation of the slider and the spiral groove. The rotating plate 52 has a sliding groove 55 inside, which provides sliding space for the sliding rod 54 to ensure that the displacement of the plug block 53 can be accurately transmitted to the rotating plate 52. The sliding rod 54 is slidably connected inside the slide groove 55. The sliding rod 54 is used to connect the wire plug block 53 and the rotating disk 52. The wire plug block 53 is fixedly connected to the outside of the sliding rod 54. The wire plug block 53 has a wire hole in the middle for guiding the wire through. The outside of the wire plug block 53 is slidably connected to the inside of the rotating disk 52. The inside of the wire plug block 53 has a hole. The limiting mechanism 4 includes a support block 41, which provides mounting support for the cylinder 42 and the push plate 44. The support block 41 is externally fixedly connected to the outside of the support plate 1, and the cylinder 42 is internally fixedly connected to the support block 41. The cylinder 42 is used to drive the push plate 44 to achieve axial limiting of the wire roll. The drive end of the cylinder 42 is fixedly connected to the push plate 44. The push plate 44 is the part that directly contacts the wire roll. The surface is covered with a rubber buffer layer, which can provide sufficient limiting force and avoid damage to the wire roll. A spring 43 is sleeved on the outside of the protruding shaft of the push plate 44. The other end of the spring 43 is fixedly connected to the outside of the support block 41. When the wire roll undergoes axial displacement, the spring 43 is compressed to generate a reverse force to return it to its original position. Specifically, during the wire feeding process of galvanized iron wire, the spiral rod 51, forged from high-quality alloy steel and surface-hardened, provides a guide track for the rotating disk 52, which is also made of high-strength alloy, through its external intersecting spiral grooves. When the iron wire passes through the wear-resistant copper alloy insertion block 53 with a polished surface, the tension change causes the stainless steel sliding rod 54 to slide within the groove 55 of the rotating disk 52, causing the rotating disk 52 to move axially along the spiral rod 51, thus achieving automatic tension adjustment. Meanwhile, the limiting plate 56, made of high-hardness engineering plastic, on the outer top of the spiral rod 51 restricts the rotation. The movement range of the moving plate 52 is designed to prevent it from detaching from the spiral rod 51. At the same time, the lightweight, high-strength aluminum alloy support block 41 is fixed to the outside of the support plate 1, providing an installation base for the cylinder 42, whose cylinder body is made of wear-resistant cast iron. The cylinder 42 drives the push plate 44, whose surface is covered with a natural rubber buffer layer, to axially limit the wire roll. When the wire roll is axially displaced, the high-elasticity spring 43 sleeved on the protruding shaft of the push plate 44 is compressed to generate a reverse force, which makes it quickly return to its position. Ultimately, this ensures that the wire maintains stable tension and position during the wire feeding process, achieving precise and efficient wire feeding operations.

[0019] The implementation principle of this application embodiment is as follows: The coiled galvanized iron wire is placed on the placement frame 3 of the wire feeding mechanism 2. The push plate 44 is driven by the cylinder 42, and the spring 43 is used to buffer the axial movement of the wire coil to prevent shaking or deviation during the wire feeding process. The motor 21 drives the drive wheel 22 to rotate, and the drive wheel 22 drives the driven wheel 23 to rotate synchronously. The driven wheel 23 drives the internal toothed ring 25 to rotate inside the support plate 1. The placement frame 3 on the top of the internal toothed ring 25 rotates accordingly to realize the wire feeding operation of the galvanized iron wire. The connecting ring 271 outside the placement frame 3 rotates synchronously with the placement frame 3. The multiple limiting plates 272 on the connecting ring 271 limit the radial movement of the wire coil through their special inclined surfaces and planes to prevent the iron wire from becoming loose or slipping during the wire feeding process.

[0020] After the wire is led out from the placement rack 3, it passes through the hole inside the insertion block 53 of the tension mechanism 5. When the wire is stretched, the insertion block 53 slides inside the rotating disk 52, while the sliding rod 54 moves in the sliding groove 55. The rotating disk 52 cooperates with the spiral rod 51 through the intersecting spiral grooves to achieve axial movement along the spiral rod 51, thereby adjusting the tension of the wire. The limiting plate 56 restricts the movement range of the rotating disk 52 to prevent it from moving excessively.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
