Description
Technical Field
[0001] This application relates to the field of metal wire processing technology, and in particular to a metal wire straightening and cutting machine. Background Technology
[0002] Metal wires are usually stored and transported in coils, which inevitably cause them to bend over time. When using metal wires, the curvature must first be eliminated by a straightening device before they are cut into smaller segments according to a set length.
[0003] Traditional straightening machines rely on multiple sets of rollers for pressure straightening and mechanical stops for positioning and cutting. However, the roller system has poor adaptability to wire diameter. When changing metal wires with large differences in wire diameter, it is necessary to manually and repeatedly adjust the roller pressure and spacing, which is cumbersome and difficult to guarantee accuracy. Summary of the Invention
[0004] To address the problem that traditional wire straightening and cutting machines require manual adjustment of roller pressure and spacing when processing wires of different diameters, which is cumbersome and difficult to guarantee accuracy, this application provides a wire straightening and cutting machine.
[0005] The metal wire straightening and cutting machine provided in this application adopts the following technical solution: A wire straightening and cutting machine, comprising: frame; The straightening device includes a probe wheel, a swing arm, a main roller, a secondary roller, a mounting plate, and a steering mechanism. The mounting plate is erected on the frame and is equipped with a support seat and a bearing seat. The steering mechanism includes a vertical guide rail and a horizontal rod fixed to the vertical guide rail. The horizontal rod is horizontally slidably connected to the mounting plate. One end of the swing arm is rotatably connected to the bearing seat. The shaft of the probe wheel is movably connected to the other end of the swing arm and the vertical guide rail, so that when the probe wheel rotates around the axis of the bearing seat, it pushes the steering mechanism to move horizontally. The support seat and the... A channel for the metal wire to pass through is formed between the detection wheels. The main roller is equipped with a transmission rod, which is slidably mounted on the mounting plate. The transmission rod is equipped with a locking block for locking its position between itself and the mounting plate. A transmission column is provided on the transmission rod. The secondary roller is fixed to the mounting plate. A channel for straightening the metal wire is formed between the main roller and the secondary roller. The horizontal rod is equipped with curved groove guide rails in the same number as the main rollers. The transmission column is embedded in the curved groove guide rails so that when the curved groove guide rails move horizontally, they drive the main rollers to move vertically. A cutting device, mounted on the frame, is used to cut metal wire; A wire feeding device, located between the straightening device and the cutting device, is used to drive the metal wire to move.
[0006] Through the above technical solution, after the metal wire is fed into the straightening device, the probe wheel first contacts the metal wire and automatically adjusts its position according to the wire's diameter, ensuring that the wire can pass smoothly through the receiving channel. At this time, the probe wheel converts its circular motion into the horizontal movement of a horizontal rod through the swing wheel and vertical guide rail. This horizontal movement is then transmitted to the transmission column via the curved groove guide rail, which in turn drives the main roller to move vertically. The transmission rod is fixed by a locking block, ensuring that the metal wire receives uniform and stable pressure during the straightening process, thereby achieving adaptive adjustment of the distance between the main roller and the secondary roller. This technical solution adaptively adjusts the distance between the main roller and the secondary roller according to the wire diameter, eliminating the need for repeated manual adjustments to the roller pressure and spacing. This avoids the problem of repeatedly manually adjusting the distance between the main roller and the secondary roller when processing multiple types of metal wires in a short period.
[0007] Optionally, the locking block includes a housing, a magnet, and a braking block. Both the housing and the braking block are U-shaped, and the braking block is embedded in the housing. The magnet is wrapped between the housing and the braking block. The locking block is detachably sleeved on the outer periphery of the transmission rod, so that the braking block abuts against the surface of the transmission rod.
[0008] With the above technical solution, the locking block can be detachably sleeved on the outer periphery of the transmission rod, and the magnetic force of the magnet presses the brake block tightly onto the transmission rod, so that the transmission rod is stably fixed to the mounting plate and prevents the transmission rod from slipping during the straightening of the metal wire.
[0009] Optionally, the frame is provided with a groove corresponding to the locking block, and the bottom surface of the groove is provided with an in-groove magnet opposite to the magnetic pole of the magnet.
[0010] With the above technical solution, the frame is provided with a groove, and a groove magnet with the opposite magnetic pole to that of the locking block magnet is installed in the groove. When the locking block presses against the transmission rod, the magnet is attracted to the groove magnet. The inner wall of the groove also provides a certain support force to the outer shell that encloses the magnet, preventing the locking block from vibrating.
[0011] Optionally, the brake block is made of rubber.
[0012] The above technical solution utilizes the large coefficient of friction of the rubber brake block to further ensure that the transmission rod is stably fixed to the mounting plate, preventing the transmission rod from slipping during the straightening of the metal wire.
[0013] Optionally, the straightening device is further provided with a flared opening for guiding the metal wire into the detection wheel.
[0014] Through the above technical solution, the flared mouth has a certain guiding function, which can help the metal wire maintain a certain straightness during the feeding process, laying the foundation for subsequent straightening operations.
[0015] Optionally, a plurality of guide blocks are provided between the horn and the detection wheel, and the guide blocks are detachably mounted on the mounting plate.
[0016] Through the above technical solution, the guide block can play a preliminary straightening role, making the metal wire closer to a straight line before entering the probe wheel, thus preparing for the subsequent straightening work of the main roller and secondary roller. Optionally, the rotating shaft is provided with a bearing and is connected to the vertical guide rail through the bearing.
[0017] Through the above technical solution, the bearing reduces the friction between the rotating shaft and the vertical guide rail, reduces energy loss, and makes the movement between the detection wheel and the vertical guide rail smoother.
[0018] Optionally, the transmission column is fitted with a bearing and connected to the curved groove guide rail through the bearing.
[0019] Through the above technical solution, the bearing reduces the friction between the transmission column and the curved groove guide rail, reduces energy loss, and makes the movement between the probe wheel and the vertical guide rail smoother.
[0020] Optionally, the wire feeding device includes a motor, a conveyor belt, a drive gear, a first gear, a second gear, a third gear, a fourth gear, a transition gear, a first wire feeding wheel, a second wire feeding wheel, a third wire feeding wheel, and a fourth wire feeding wheel. The motor is connected to the drive gear via the conveyor belt. The first gear, the second gear, the third gear, and the fourth gear are respectively connected to the first wire feeding wheel, the second wire feeding wheel, the third wire feeding wheel, and the fourth wire feeding wheel via the same rotating shaft. The drive gear meshes externally with the first gear, the first gear meshes externally with the second gear, the drive gear also meshes externally with the transition gear, the transition gear meshes externally with the third gear, and the third gear meshes externally with the fourth gear.
[0021] Through the above technical solution, the high-speed rotation of the motor of the wire feeding mechanism is effectively transmitted to the drive gear through the conveyor belt. The drive gear is then driven by a series of external meshing gears, so that the four wire feeding wheels can rotate at a predetermined speed and direction, realizing the synchronous feeding of metal wire by the two sets of wire feeding wheels. This not only simplifies the mechanical structure, but also improves work efficiency.
[0022] Optionally, the first, second, third, and fourth wire feeding wheels are all fitted with rubber rings on their circumferential surfaces, and a V-groove is provided at the middle position of the circumferential surface of the rubber ring.
[0023] Through the above technical solution, the rubber ring has a certain buffering effect, which can reduce the hard collision between the metal wire and the wire feeding wheel, reduce noise, and extend the service life of the wire feeding wheel. The V-groove design helps to fix the metal wire and prevent the metal wire from sliding laterally, so that the wire feeding device can deliver the metal wire more stably and efficiently.
[0024] In summary, this application has at least the following beneficial technical effects: 1. The metal wire straightening and cutting machine proposed in this application has a probe wheel that adjusts its position according to the diameter of the metal wire. The circular motion of the probe wheel is converted into the horizontal movement of a horizontal rod through a swing wheel and a steering mechanism. Then, the transmission column is driven to move along the track of the curved groove guide rail on the horizontal rod, converting the horizontal movement of the curved groove guide rail on the horizontal rod into the vertical movement of the transmission column, thereby driving the main roller to move in the vertical direction. Finally, the transmission shaft is fixed by a locking block, thereby fixing the distance between the main roller and the secondary roller. The above technical solution realizes the adaptive adjustment of the distance between the main roller and the secondary roller according to the diameter of the metal wire, eliminating the need for repeated manual adjustment of roller pressure and spacing, and avoiding the problem of repeatedly manually adjusting the distance between the main roller and the secondary roller when processing multiple types of metal wires in a short period of time.
[0025] 2. The bell mouth and guide block ensure that the metal wire is gradually guided and calibrated before entering the detection wheel, making the wire nearly straight before entering the wheel. This prevents the wire from being excessively skewed or twisted, which could affect the detection wheel's monitoring of the wire diameter. Furthermore, the guide block also provides initial straightening, preparing for subsequent straightening operations on the main and secondary rollers.
[0026] 3. The rotating shaft is rotatably connected to the vertical guide rail via bearings, and the transmission column is rotatably connected to the curved groove guide rail via bearings. This changes sliding into rolling, reducing friction and energy loss, making the motion transmission between the probe wheel and the vertical guide rail, and between the transmission column and the curved groove guide rail, smoother. It also improves the stability and service life of the rotating shaft and the transmission column, ensuring the accuracy and reliability of the wire straightening and cutting machine during operation.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] This application discloses a wire straightening and cutting machine, including a frame 1, a straightening device 2, a cutting device 3, and a wire feeding device 4. The straightening device 2 includes a probe wheel 21, a swing arm 22, a main roller 23, a secondary roller 24, a mounting plate 25, and a steering mechanism 26. The mounting plate 25 is erected on the frame 1 and is equipped with a support seat 251 and a bearing seat 252. The steering mechanism 26 includes a vertical guide rail 261 and a horizontal rod 262 fixed to the vertical guide rail 261. The horizontal rod 262 is horizontally slidably connected to the mounting plate 25. One end of the swing arm 22 is rotatably connected to the bearing seat 252. The shaft of the probe wheel 21 is movably connected to the other end of the swing arm 22 and the vertical guide rail 261, so that when the probe wheel 21 rotates around the axis of the bearing seat 252, it pushes the steering mechanism 26 to move horizontally. The support... A receiving channel for the metal wire 5 is formed between the seat 251 and the detection wheel 21. The main roller 23 is provided with a transmission rod 27, which is slidably mounted on the mounting plate 25. The transmission rod 27 is provided with a locking block 6 for locking its position between itself and the mounting plate 25. A transmission column 271 is provided on the transmission rod 27. The secondary roller 24 is fixed to the mounting plate 25. A channel for straightening the metal wire is formed between the main roller 23 and the secondary roller 24. The horizontal rod 262 is provided with curved groove guide rails 263 in the same number as the main roller 23. The transmission column 271 is embedded in the curved groove guide rails 263 so that when the curved groove guide rails 263 move horizontally, they drive the main roller 23 to move vertically. The cutting device 3 is mounted on the frame 1 and is used to cut the metal wire 5. The wire feeding device 4 is located between the straightening device 2 and the cutting device 3 and is used to drive the metal wire 5 to move.
[0034] Specifically, refer to Figure 1 and Figure 2This embodiment proposes a wire straightening and cutting machine, including a frame 11 and a straightening device 22. The straightening device 22 includes a probe wheel 21, a swing arm 22, a main roller 23, a secondary roller 24, a mounting plate 25, and a steering mechanism 26. The mounting plate 25 is erected on the frame 11. The steering mechanism 26 includes a vertical guide rail 261 and a horizontal rod 262 fixed to the vertical guide rail 261. The horizontal rod 262 is slidably connected to the mounting plate 25. Specifically, two connecting seats 253 extend horizontally from the mounting plate 25. The connecting seats 253 have through holes for the horizontal rod 262 to pass through. The horizontal rod 262 passes through the through holes of the two connecting seats 253 in sequence and can slide horizontally along the two through holes, thus realizing the horizontal sliding connection between the horizontal rod 262 and the mounting plate 25. The mounting plate 25 is also provided with a support seat 251. The support seat 251 has a groove, and the probe wheel 21 cooperates with the support seat 251 to form a channel for the wire 5 to pass through. It should be noted that there are accommodating channels for the movement of the metal wire 5 between the main roller 23 and the secondary roller 24, the cutting device 3, and the wire feeding device 4. One end of the swing arm 22 is rotatably connected to the bearing seat 252 on the mounting plate 25, and the other end of the swing arm 22 is hinged to the shaft of the probe wheel 21. At the same time, the shaft of the probe wheel 21 is also connected to the vertical guide rail 261, and the shaft of the probe wheel 21 can slide vertically along the track of the vertical guide rail 261. When the probe wheel 21 makes a circular motion around the axis of the bearing seat 252, the shaft of the probe wheel 21 slides vertically along the track of the vertical guide rail 261, and at the same time, it will drive the vertical guide rail 261 and the horizontal rod 262 to make a horizontal motion along the line connecting the two connecting seats 253 on the mounting plate 25, thereby converting the circular motion of the probe wheel 21 into the vertical movement of the shaft of the probe wheel 21 relative to the vertical guide rail 261 and the horizontal movement of the vertical guide rail 261. The main roller 23 is equipped with a transmission rod 27, which is slidably mounted on the mounting plate 25. A transmission column 271 is mounted on the transmission rod 27. The secondary roller 24 is fixed to the mounting plate 25, and the main roller 23 and secondary roller 24 are arranged in two staggered rows. The horizontal rod 262 is equipped with a number of curved groove guide rails 263 corresponding to the number of main rollers 23. The transmission column 271 is embedded in the curved groove guide rails 263 and can slide along their tracks. When the horizontal rod 262 moves horizontally, the transmission column 271 slides along the tracks of the curved groove guide rails 263. Because the transmission rod 27 can only slide vertically, the horizontal movement of the horizontal rod 262 is converted into vertical movement of the main roller 23 via the curved groove guide rails 263. The cutting device 3 is mounted on the frame 1 and is used to cut the metal wire 5. The wire feeding device 4 is located between the straightening device 2 and the cutting device 3 and is used to drive the metal wire 5 to move.
[0035] In addition, a locking block 6 is provided between the transmission rod 27 and the mounting plate 25. The locking block 6 can be a locking bolt, a spring locking mechanism, etc., used to fix the transmission rod 27 on the mounting plate 25 after the position of the main roller 23 is adjusted, to prevent the transmission rod 27 from slipping during the straightening of the metal wire 5 and affecting the straightening effect. When it is necessary to adjust the position of the main roller 23, simply loosen the locking block 6, and then the probe wheel 21 will move horizontally based on the diameter of the metal wire 5 through the vertical guide rail 261 to drive the horizontal rod 262 to move horizontally, and then through the curved groove guide rail 263 to drive the transmission column 271 and the transmission rod 27, thereby adjusting the position of the main roller 23. After the adjustment is completed, the locking block 6 is locked again to make the transmission rod 27 stably fixed to the mounting plate 25.
[0036] The working principle of the adaptive adjustment main roller 23 of the metal straightening machine in this embodiment is as follows: When the locking block 6 between the transmission rod 27 and the mounting plate 25 is released, the metal wire 5 passes through the receiving channel under the probe wheel 21. The metal wire 5 will support the probe wheel 21 to rotate around the axis of the bearing seat 252 connected to the swing arm 22. The rotating shaft of the probe wheel 21 will move upward along the vertical guide rail 261 relative to the vertical guide rail 261, and push the vertical guide rail 261 and the horizontal rod 262 to move to the right. That is to say, the circular motion of the swing arm 22 will be converted into the vertical motion of the rotating shaft of the probe wheel 21 along the vertical guide rail 261 and the horizontal motion of the vertical guide rail 261. At this time, the curved groove guide rail 263 on the horizontal rod 262 will also move to the right. The transmission column 271 located in the curved groove of the curved groove guide rail 263 will move along the curved groove trajectory, thereby driving the main roller 23 and the transmission rod 27 to move in the vertical direction, thereby realizing the adjustment of the distance between the main roller 23 and the secondary roller 24.
[0037] Through the above technical solution, the probe wheel 21 adjusts its position according to the diameter of the metal wire 5, and the circular motion of the probe wheel 21 is converted into the horizontal movement of the horizontal rod 262 through the swing wheel and the steering mechanism 26. Then, the transmission column 271 is driven to move along the track of the curved groove guide rail 263 on the horizontal rod 262, so that the horizontal movement of the curved groove guide rail 263 on the horizontal rod 262 is converted into the vertical movement of the transmission column 271, thereby driving the main roller 23 to move in the vertical direction. Finally, the transmission shaft is fixed by the locking block 6, thereby fixing the distance between the main roller 23 and the secondary roller 24. The above technical solution realizes the adaptive adjustment of the distance between the main roller 23 and the secondary roller 24 according to the diameter of the metal wire 5, without the need for manual and repeated adjustment of the roller pressure and spacing, avoiding the problem of repeatedly manually adjusting the distance between the main roller 23 and the secondary roller 24 when processing metal wires 5 of various diameters in a short period of time.
[0038] In one specific embodiment, the locking block 6 includes a housing 61, a magnet 62, and a braking block 63. Both the housing 61 and the braking block 63 are U-shaped, and the braking block 63 is embedded in the housing 61. The magnet 62 is wrapped between the housing 61 and the braking block 63. The locking block 6 is detachably sleeved on the outer periphery of the transmission rod 27, such that the braking block 63 abuts against the surface of the transmission rod 27.
[0039] The wire straightening and cutting machine proposed in this application straightens wires 5 with a diameter range of 1mm to 5mm. The wires 5 are made of common metals such as copper, aluminum, and iron. The secondary roller 24 is directly fixed to the mounting plate 25, so a certain support force needs to be provided to the main roller 23 to allow the main roller 23 and the secondary roller 24 to cooperate in straightening the wires 5. Since the diameter of the wires 5 is not large and they are all common metals that are easily deformed, it is not necessary to provide a large support force to the main roller 23. It is only necessary to use the locking block 6 to fix the transmission rod 27 to stabilize the main roller 23.
[0040] Reference Figure 2 The locking block 6 includes a housing 61, a magnet 62, and a brake block 63. The housing 61 is made of a hard material, possessing a certain strength and wear resistance, to protect the internal magnet 62. The magnet 62 has strong magnetism and can be attracted to the frame 1 to fix the locking block 6. The brake block 63 has a certain elasticity and friction. The housing 61, magnet 62, and brake block 63 are all U-shaped as a whole. The housing 61 encloses the magnet 62. The shorter U-shaped curved surface of the housing 61 connects with the longest U-shaped curved surface of the brake block 63. The shortest U-shaped curved surface of the brake block 63 will closely fit the transmission rod 27, achieving braking of the transmission rod 27 through friction.
[0041] Through the above technical solution, the magnetic force of the magnet 62 presses the brake block 63 tightly against the transmission rod 27, preventing the transmission rod 27 from slipping during the straightening process of the metal wire 5. In addition, the overall U-shaped structure of the locking block 6 fits against the surface of the transmission rod 27, so that it can evenly distribute pressure when pressing against the transmission rod 27, avoiding damage or deformation of the transmission rod 27 caused by excessive local pressure.
[0042] In one specific embodiment, the frame 1 is provided with a groove corresponding to the locking block 6, and the bottom surface of the groove is provided with an in-groove magnet opposite to the magnetic pole of the magnet 62.
[0043] To prevent the magnet 62 from vibrating and weakening its magnetic force during the operation of the straightening device 2, a groove corresponding to the locking block 6 is provided on the frame 1. The bottom surface of the groove is provided with a slot magnet with the opposite magnetic pole to that of the magnet 62. When the locking block 6 presses against the transmission rod 27, the magnet 62 is attracted to the slot magnet. The inner wall of the groove also provides a certain support force to the outer shell 61 that encloses the magnet 62, preventing the locking block 6 from vibrating. This ensures that the brake block 63 is pressed tightly against the transmission rod 27, preventing the transmission rod 27 from slipping during the straightening process of the metal wire 5.
[0044] In one specific embodiment, the brake block 63 is made of rubber.
[0045] Through the above technical solution, the large coefficient of friction of the rubber brake block 63 further ensures that the transmission rod 27 is stably fixed to the mounting plate 25, preventing the transmission rod 27 from slipping during the straightening process of the metal wire 5.
[0046] In one specific embodiment, the straightening device 2 is further provided with a flared mouth 28 for guiding the metal wire 5 into the detection wheel 21.
[0047] Reference Figure 1 The straightening device 2 is also equipped with a bell mouth 28, the opening of which faces the opposite direction to the wire feeding direction during the processing of the metal wire 5. The bell mouth 28 can ensure that the metal wire 5 can be gradually guided and calibrated before entering the probe wheel 21, so that it is close to a straight state before entering the probe wheel 21, thereby avoiding the metal wire 5 from being affected by excessive skew or twisting, which would affect the probe wheel 21's monitoring of the diameter of the metal wire 5.
[0048] In one specific embodiment, a plurality of guide blocks 29 are provided between the horn 28 and the detection wheel 21, and the guide blocks 29 are detachably mounted on the mounting plate 25.
[0049] Reference Figure 1 To further guide and support the metal wire 5, ensuring it remains in a relatively stable feeding position before entering the detector wheel 21 without excessive deviation, several guide blocks 29 are installed between the flared opening 28 and the detector wheel 21. Each guide block 29 has a circular channel for the metal wire 5 to pass through. The diameter of the circular channel between any two adjacent guide blocks 29 gradually decreases along the wire 5's feeding direction, thus gradually guiding the metal wire 5 into the receiving channel formed between the detector wheel 21 and the support base 251, ensuring the metal wire 5 is nearly straight before entering the detector wheel 21. The guide blocks 29 are detachably mounted to the mounting plate 25 using bolts, clips, pins, etc. When the diameter of the metal wire 5 is small, the corresponding guide block 29 can be replaced at any time to accommodate metal wires of different diameters.
[0050] Through the above technical solution, the guide block 29 can perform a preliminary straightening function, making the metal wire 5 closer to a straight state before entering the probe wheel 21, thus preparing for the subsequent straightening work of the main roller 23 and the secondary roller 24. In addition, the guide block 29 can also be disassembled and replaced to accommodate metal wires 5 of different diameters.
[0051] In one specific embodiment, the rotating shaft is provided with a bearing 7 and is connected to the vertical guide rail 261 through the bearing 7.
[0052] Specifically, refer to Figure 1 The rotating shaft is rotatably connected to the vertical guide rail 261 through the bearing 7. The bearing 7 reduces the friction between the rotating shaft and the vertical guide rail 261, reduces energy loss, makes the movement between the probe wheel 21 and the vertical guide rail 261 smoother, and can improve the stability and service life of the rotating shaft, ensuring the accuracy and reliability of the wire straightening and cutting machine during operation.
[0053] In one specific embodiment, the transmission column 271 is fitted with a bearing 7 and connected to the curved groove guide rail 263 through the bearing 7.
[0054] Specifically, refer to Figure 3 The transmission column 271 is rotatably connected to the curved groove guide rail 263 through the bearing 7, which changes the sliding between the transmission column 271 and the curved groove guide rail 263 into rolling, reducing the friction between the transmission column 271 and the curved groove guide rail 263, thus making the transmission smoother, and improving the stability and service life of the transmission column 271, ensuring the accuracy and reliability of the wire straightening and cutting machine during operation.
[0055] In one specific embodiment, the wire feeding device 4 includes a motor 41, a conveyor belt 42, a drive gear 43, a first gear 44, a second gear 45, a third gear 46, a fourth gear 47, a transition gear 48, a first wire feeding wheel 49, a second wire feeding wheel 410, a third wire feeding wheel 411, and a fourth wire feeding wheel 412. The motor 41 is connected to the drive gear 43 via the conveyor belt 42. The first gear 44, the second gear 45, the third gear 46, and the fourth gear 47 are respectively connected to the first wire feeding wheel 49, the second wire feeding wheel 410, the third wire feeding wheel 411, and the fourth wire feeding wheel 412 via the same rotating shaft. The drive gear 43 meshes externally with the first gear 44, the first gear 44 meshes externally with the second gear 45, the drive gear 43 also meshes externally with the transition gear 48, the transition gear 48 meshes externally with the third gear 46, and the third gear 46 meshes externally with the fourth gear 47.
[0056] Reference Figure 3 and Figure 4The wire feeding device 4 includes a motor 41, a conveyor belt 42, a drive gear 43, a first gear 44, a second gear 45, a third gear 46, a fourth gear 47, a connecting gear 48, a first wire feeding wheel 49, a second wire feeding wheel 410, a third wire feeding wheel 411, and a fourth wire feeding wheel 412. The motor 41 is indirectly connected to the drive gear 43 via the conveyor belt 42. Specifically, a drive wheel is mounted on the drive shaft of the motor 41. The motor 41 drives the drive shaft to rotate, which in turn drives the drive wheel to rotate. The drive wheel then drives the drive gear 43 to rotate via the conveyor belt 42. The first gear 44, the second gear 45, the third gear 46, and the fourth gear 47 are respectively connected to the first wire feeding wheel 49, the second wire feeding wheel 410, the third wire feeding wheel 411, and the fourth wire feeding wheel 412 via the same rotating shaft. That is, the rotation of the first gear 44 will drive the first wire feeding wheel 49 to rotate, and the same applies to the second wire feeding wheel 410, the third wire feeding wheel 411, and the fourth wire feeding wheel 412. The wire feeding wheels are divided into two groups. The first group consists of the first wire feeding wheel 49 and the second wire feeding wheel 410, and the second group consists of the first wire feeding wheel 49 and the fourth wire feeding wheel 412. The metal wire 5 is fed synchronously through the two groups of wire feeding wheels.
[0057] The drive gear 43 meshes externally with the first gear 44, and the first gear 44 meshes externally with the second gear 45. When the drive gear 43 rotates, it drives the first gear 44 to rotate, and the first gear 44 then drives the second gear 45 to rotate. The rotation directions of the first gear 44 and the second gear 45 are opposite, so the rotation directions of the first wire feeding wheel 49 and the second wire feeding wheel 410 are also opposite, thereby realizing the feeding of the metal wire 5 by the first set of wire feeding wheels. The drive gear 43 also meshes externally with the adapter gear 48, the adapter gear 48 meshes externally with the third gear 46, and the third gear 46 meshes externally with the fourth gear 47. The drive gear 43 drives the adapter gear 48 to rotate, the adapter gear 48 drives the third gear 46 to rotate, and the third gear 46 then drives the fourth gear 47 to rotate. Compared to the first gear 44 and the second gear 45, an adapter gear 48 is added before the drive gear 43 drives the third gear 46 and the fourth gear 47 to rotate, so the first gear 44 and the fourth gear 47 in the same row, and the second gear 45 and the third gear 46 in the same row rotate in the same direction. This makes the first wire feeding wheel 49 and the fourth wire feeding wheel 412 in the same row, and the second wire feeding wheel 410 and the third wire feeding wheel 411 in the same row rotate in the same direction, thereby ensuring that the first set of wire feeding wheels and the second set of wire feeding wheels convey the metal wire 5 in the same direction, thereby increasing the conveying force on the metal wire 5.
[0058] In addition, the wire feeding device 4 is also designed with a fine-tuning mechanism, which can precisely adjust the spacing between each wire feeding wheel to accommodate metal wires 5 of different diameters.
[0059] Through the above technical solution, the high-speed rotation of the motor 41 of the wire feeding mechanism is effectively transmitted to the drive gear 43 through the conveyor belt 42. The drive gear 43 then transmits power through a series of external meshing gears, enabling the four wire feeding wheels to rotate at a predetermined speed and direction, thereby achieving synchronous feeding of the metal wire 5 by the two sets of wire feeding wheels. This not only simplifies the mechanical structure but also improves work efficiency.
[0060] In one specific embodiment, the first wire feeding wheel 49, the second wire feeding wheel 410, the third wire feeding wheel 411 and the fourth wire feeding wheel 412 are all fitted with rubber rings on their circumferential surfaces, and a V-shaped groove is provided at the middle position of the circumferential surface of the rubber ring.
[0061] Reference Figure 3 To further enhance the friction between the wire feeding wheels and the metal wire 5, ensuring that the metal wire 5 does not slip or get stuck during conveying, rubber rings are fitted onto the circumferential surfaces of the first wire feeding wheel 49, the second wire feeding wheel 410, the third wire feeding wheel 411, and the fourth wire feeding wheel 412. The rubber rings are typically fixed to the wire feeding wheels using an interference fit or adhesive to ensure synchronous rotation. A V-groove is provided in the middle of the circumferential surface of the rubber ring, and the V-groove of the rubber ring in each set of wire feeding wheels forms a receiving channel for conveying the metal wire 5. The rubber ring can produce moderate elastic deformation when in contact with the metal wire 5, thereby increasing the contact area and friction. Simultaneously, the V-groove design helps to fix the metal wire 5 and prevent lateral slippage. Furthermore, the rubber rings can be adjusted according to different metal wire materials and specifications to adapt to the processing requirements of different types of metal wire 5.
[0062] Through the above technical solution, the rubber ring has a certain buffering effect, which can reduce the hard collision between the metal wire 5 and the wire feeding wheel. The rubber ring can be adjusted according to different metal wire 5 materials and specifications to adapt to the processing needs of different types of metal wire 5, reduce noise, and extend the service life of the wire feeding wheel. At the same time, the V-groove design of the rubber ring helps to fix the metal wire 5 and prevent the metal wire 5 from sliding laterally, so that the wire feeding device 4 can convey the metal wire 5 more stably and efficiently.
[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
