Description

Technical Field

[0001] This invention relates to the field of copper wire processing, and in particular to a flat copper wire pressing and rolling processing equipment. Background Technology

[0002] Copper wire refers to wire made by pressing or drawing copper. Copper wire has a wide range of applications, including manufacturing electrical wires, cables, brushes, and for use in compasses, aviation instruments, etc. Due to its good plasticity, copper wire is also very easy to process by hot and cold pressing. There are many varieties of copper wire. According to alloy grade, it can be divided into leaded brass wire, pure copper wire, oxygen-free copper wire, etc. According to cross-sectional shape, it can be divided into round copper wire, flat wire, shaped wire, etc.

[0003] The production process of flat copper wire requires the use of a pressing and rolling equipment. This equipment mainly consists of a feed roller, a take-up roller, and pressing rollers. During operation, the round copper wire unwound from the feed roller is flattened as it passes through the pressing rollers. The flattened copper wire is then wound up and collected by the take-up roller. However, the pressing and rolling equipment has the following problems in practical applications:

[0004] 1. In the existing technology, the pay-off roller, take-up roller, and pressing roller are all placed horizontally. Both ends of the horizontally placed pay-off roller, take-up roller, and pressing roller need to be supported by mounting brackets. This makes it inconvenient to remove the flattened copper wire from the take-up roller. Furthermore, since the flat copper wire is wound tightly on the take-up roller during the winding process, it is not convenient to remove the entire bundle of flat copper wire from the take-up roller after winding is completed.

[0005] 2. In actual production, the thickness of flat copper wire varies, so it is necessary to adjust the distance between the two sets of pressing rollers to meet the thickness requirements in actual production. However, since both ends of the two sets of pressing rollers are movably mounted on the mounting frame, the mounting frame needs to be removed if the distance between the two sets of pressing rollers is to be adjusted, which is time-consuming and laborious.

[0006] Therefore, it is necessary to invent a flat copper wire rolling processing equipment to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a flat copper wire rolling processing device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a flat copper wire pressing and rolling processing device, comprising a wire feeding roller for feeding wire, a pressing and rolling assembly for flattening round copper wire, and a winding assembly for winding the flat copper wire after pressing and rolling. The pressing and rolling assembly includes a first pressing and rolling roller and a second pressing and rolling roller placed vertically and parallel to each other. The first pressing and rolling roller and the second pressing and rolling roller rotate relative to each other. A pressing and rolling sleeve is provided on the outside of the second pressing and rolling roller. The pressing and rolling sleeve is stationary relative to the second pressing and rolling roller. Several sets of pressing and rolling sleeves are provided. The upper and lower ends of the pressing and rolling sleeve are provided with protruding edges for limiting the flat copper wire.

[0009] The winding assembly includes a vertically placed take-up roller that rotates around its own axis. The pay-off roller and the take-up roller are arranged parallel to each other. The outer periphery of the take-up roller is provided with several sets of arc-shaped plates that can move back and forth along its radial direction. The several sets of arc-shaped plates are arranged in an equidistant ring around the axis of the take-up roller. A baffle is fixedly provided at the bottom end of the take-up roller, and a baffle is detachably provided at the top end of the take-up roller.

[0010] Preferably, the outer surface of the arc plate is provided with a wire embedding groove, the inside of the wire embedding groove is embedded with a binding rope, the baffles at both ends of the take-up roller are provided with through slots for the binding rope to pass through, the through slots are positioned corresponding to the wire embedding groove, and the two sets of baffles are provided with clamping components for clamping and fixing the two ends of the binding rope.

[0011] Preferably, the top of the take-up roller has a columnar slot, and a push rod is fixedly provided on the side of the arc-shaped plate facing the take-up roller. The push rod passes through the first insertion slot on the take-up roller and enters the interior of the columnar slot. A cylindrical cylinder coaxial with the push rod is also fixedly provided inside the columnar slot. The end of the push rod away from the arc-shaped plate passes through the second insertion slot on the cylindrical cylinder and enters the interior of the cylindrical cylinder. A protrusion is fixedly provided on the push rod at the part between the take-up roller and the cylindrical cylinder. The side of the protrusion facing the cylindrical cylinder is fixedly connected to the outer surface of the cylindrical cylinder by a tension spring. A drive assembly for pushing the push rod outward of the cylindrical cylinder is provided inside the columnar slot.

[0012] Preferably, the drive assembly includes an anti-slip plate, a rotating disk, a rotating rod, and an arc-shaped push plate. The baffle plate at the top of the take-up roller is movably covered at the port of the columnar slot, and the bottom of the baffle plate at the port of the columnar slot is fixedly provided with an anti-slip plate. The anti-slip plate is embedded at the port of the columnar slot. The bottom of the anti-slip plate is fixedly connected to the rotating rod. The rotating disk is fixedly provided on the rotating rod. The outer periphery of the rotating disk is provided with an arc-shaped push plate, which is arranged in a ring around the axis of the rotating disk.

[0013] Preferably, the clamping assembly includes a clamping plate, the clamping plate having a plurality of clamping slots, the number of clamping slots being equal to the number of wire embedding slots, and the inner wall of the clamping slots being fixedly provided with an elastic pad for elastically compressing the binding rope.

[0014] Preferably, the clamping slot is a V-shaped structure, and the port of the clamping slot faces the outside of the clamping plate, and the elastic pad is a V-shaped structure that matches the clamping slot.

[0015] Preferably, the inner wall of the elastic pad has a wavy structure with protrusions and recesses, and the protrusions on two opposite inner walls of the elastic pad are in a one-to-one correspondence.

[0016] Preferably, an annular receiving groove is provided inside the second pressing roller at a position corresponding to the pressing sleeve. Inside one set of the annular receiving grooves are several sets of electric push rods arranged in an equidistant annular pattern around the axis of the second pressing roller. The fixed end of the electric push rod is fixedly connected to the bottom of the annular receiving groove, and the free end of the electric push rod is braced in the insertion groove of the inner wall of the pressing sleeve. The electric push rods are distributed radially along the second pressing roller.

[0017] Preferably, the side of the arc-shaped plate facing the take-up roller has a hook groove, the bottom of the hook groove has a V-shaped structure, and the direction of the hook groove is parallel to the axis of the take-up roller.

[0018] Preferably, the first and second pressing rollers are both movably mounted on the mounting platform. The bottom of both the first and second pressing rollers is fixedly provided with spur gears, and the two sets of spur gears mesh with each other. The rotating shaft at the bottom of the first pressing roller is connected to the drive motor. The take-up roller and the unwinding roller are both movably mounted on the mounting platform, and the rotating shaft at the bottom of the take-up roller is connected to the drive motor.

[0019] The technical effects and advantages of this invention are as follows:

[0020] 1. In this invention, the second pressing roller is fitted with a pressing sleeve, so the gap between the first pressing roller and the second pressing roller can be changed by replacing the pressing sleeve of different sizes, thereby pressing out copper wires of different thicknesses. The convex edges at both ends of the pressing sleeve play a role in guiding and limiting the copper wires. In practical applications, multiple pressing sleeves of the same size can be fitted on the second pressing roller, so that multiple rolls of copper wire can be pressed and formed at the same time. Alternatively, multiple pressing sleeves of different sizes can be fitted on the outside of the second pressing roller, so that multiple sets of flat copper wires of different thicknesses can be pressed out at the same time.

[0021] 2. The take-up roller is provided with an arc-shaped plate that can be moved closer to or further away from it. When the arc-shaped plate is in a position away from the take-up roller, the flat copper wire is wound around the outside of the "cylindrical-like tube" formed by the arc-shaped plate. After the winding is finished, the arc-shaped plate can be controlled to move closer to the take-up roller, so that there is a gap between the wound wire bundle and the arc-shaped plate, making it easy to peel the wire bundle off the outside of the arc-shaped plate.

[0022] 3. When replacing the roller sleeve or removing the wire harness, the present invention does not require detaching one end of the second roller or one end of the take-up roller from the mounting frame, thus saving time and effort and making the operation convenient. At the same time, it can also effectively prevent the first roller, the second roller, the pay-off roller and the take-up roller from being covered with dust.

[0023] 4. After winding is finished, the two ends of the binding rope can be directly tied together to bind the wire harness. After binding, move the arc plate closer to the take-up roller to create a gap between the arc plate and the wire harness, making it easier to remove the wire harness from the outside of the arc plate.

[0024] 5. The clamping slot is designed as a V-shaped structure. The inside of the clamping slot can clamp binding ropes of different thicknesses. Thicker binding ropes are clamped near the port of the elastic pad, while thinner binding ropes need to be embedded inside the elastic pad away from the port to be clamped. The inner wall of the elastic pad has a wavy structure, which can increase the frictional resistance between the binding rope and the inner wall of the elastic pad, thereby preventing the binding rope from detaching from the inside of the elastic pad.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] This invention provides, for example Figures 1-10The flat copper wire pressing and rolling equipment shown includes a wire feeding roller 8 for feeding the wire, a pressing and rolling assembly for flattening the round copper wire, and a winding assembly for winding the flat copper wire after pressing and rolling. The pressing and rolling assembly includes a first pressing roller 1 and a second pressing roller 2 placed vertically and parallel to each other. The first pressing roller 1 and the second pressing roller 2 rotate relative to each other. A pressing sleeve 3 is sleeved on the outside of the second pressing roller 2. The pressing sleeve 3 is stationary relative to the second pressing roller 2. Several sets of pressing sleeves 3 are provided. The upper and lower ends of the pressing sleeve 3 are provided with protruding edges 4 for limiting the flat copper wire.

[0039] The winding assembly includes a vertically placed take-up roller 9 that rotates around its own axis. The pay-off roller 8 is arranged parallel to the take-up roller 9. The take-up roller 9 has several sets of arc-shaped plates 10 that can move back and forth along its radial direction around its periphery. The several sets of arc-shaped plates 10 are arranged in an equidistant ring around the axis of the take-up roller 9. The bottom end of the take-up roller 9 is fixedly provided with a baffle plate 12, and the top end of the take-up roller 9 is detachably provided with a baffle plate 12.

[0040] In actual operation, the round copper wire released from the feed roller 8 is flattened as it passes between the first pressing roller 1 and the second pressing roller 2. The flattened copper wire is then wound around the outside of the "quasi-cylindrical tube" formed by the arc-shaped plates 10. Since a pressing sleeve 3 is fitted around the outside of the second pressing roller 2, the gap between the first pressing roller 1 and the second pressing roller 2 can be changed by replacing the pressing sleeve 3 with different sizes, thereby pressing out copper wires of different thicknesses. For example, if the outer diameter of the pressing sleeve 3 is larger, the gap formed between the first pressing roller 1 and the pressing sleeve 3 is smaller, and the thickness of the pressed copper wire is smaller. Similarly, when the outer diameter of the pressing sleeve 3 is smaller, the gap formed between the first pressing roller 1 and the pressing sleeve 3 is smaller. The gap is relatively large, and the thickness of the copper wire after being pressed by the first pressing roller 1 and the pressing sleeve 3 is relatively large. The protruding edges 4 at both ends of the pressing sleeve 3 play a role in guiding and limiting the copper wire. In practical applications, multiple pressing sleeves 3 of the same size can be fitted on the second pressing roller 2, so that multiple rolls of copper wire can be pressed and formed at the same time. Alternatively, multiple pressing sleeves 3 of different sizes can be fitted on the outside of the second pressing roller 2, so that multiple sets of flat copper wires of different thicknesses can be pressed and rolled at the same time. It should be noted that the distance between the two sets of protruding edges 4 on the pressing sleeve 3 should match the gap between the first pressing roller 1 and the pressing sleeve 3. That is, when a round copper wire of a fixed diameter is flattened to a certain thickness, its width is also fixed.

[0041] Furthermore, the take-up roller 9 is provided with an arc-shaped plate 10 that can move closer to or further away from it. When the arc-shaped plate 10 is in a position away from the take-up roller 9, the flat copper wire is wound around the outside of the "cylindrical-like tube" formed by the arc-shaped plate 10. After the winding is finished, the arc-shaped plate 10 can be controlled to move closer to the take-up roller 9, so that there is a gap between the wound wire bundle and the arc-shaped plate 10, making it convenient to peel the wire bundle off the outside of the arc-shaped plate 10.

[0042] Meanwhile, the first pressing roller 1, the second pressing roller 2, the unloading roller 8, and the take-up roller 9 in this invention are all placed vertically. The vertical placement of the second pressing roller 2 makes it easier to replace the pressing sleeve 3 on the second pressing roller 2, while the vertical placement of the take-up roller 9 makes it easier to remove the wound wire bundle outside the arc plate 10. Therefore, compared with the traditional horizontally placed rollers, this invention does not require detaching one end of the second pressing roller 2 or one end of the take-up roller 9 from the mounting frame when replacing the pressing sleeve 3 or removing the wire bundle. This not only saves time and effort but also makes the operation convenient. At the same time, it can also effectively prevent the outside of the first pressing roller 1, the second pressing roller 2, the unloading roller 8, and the take-up roller 9 from being covered with dust.

[0043] The outer surface of the arc plate 10 is provided with a wire embedding groove 26, and a binding rope 34 is embedded inside the wire embedding groove 26. The baffles 12 at both ends of the take-up roller 9 are provided with through slots 13 for the binding rope 34 to pass through. The through slots 13 correspond to the positions of the wire embedding groove 26. The two sets of baffles 12 are provided with clamping components to clamp and fix the two ends of the binding rope 34.

[0044] In practical applications, before winding the rolled copper wire, the binding rope 34 is first embedded in the wire groove 26 on the arc plate 10, and both ends of the binding rope 34 extend out of the through slots 13 on the baffles 12 at the upper and lower ends of the take-up roller 9. The ends of the binding rope 34 are fixed by the clamping assembly to prevent the ends of the binding rope 34 from being wound inside the copper wire bundle or wrapped in other positions when the take-up roller 9 and the arc plate 10 rotate, thus affecting the rotation of the take-up roller 9. After winding is completed, the two ends of the binding rope 34 can be directly tied together to bind the wire bundle. After binding, the arc plate 10 is moved closer to the take-up roller 9 so that there is a gap between the arc plate 10 and the wire bundle, which makes it easier to remove the wire bundle from the outside of the arc plate 10.

[0045] The top of the take-up roller 9 has a columnar slot 33. A push rod 25 is fixedly provided on the side of the arc plate 10 facing the take-up roller 9. The push rod 25 passes through the first insertion slot 28 on the take-up roller 9 and enters the interior of the columnar slot 33. A cylindrical cylinder 11 coaxial with it is also fixedly provided inside the columnar slot 33. The end of the push rod 25 away from the arc plate 10 passes through the second insertion slot 29 on the cylindrical cylinder 11 and enters the interior of the cylindrical cylinder 11. A protruding rod 27 is fixedly provided on the part of the push rod 25 located between the take-up roller 9 and the cylindrical cylinder 11. The side of the protruding rod 27 facing the cylindrical cylinder 11 is fixedly connected to the outer surface of the cylindrical cylinder 11 by a tension spring. The interior of the columnar slot 33 is provided with a drive assembly that pushes the push rod 25 outward of the cylindrical cylinder 11.

[0046] In actual operation, when the drive assembly pushes the push rod 25 away from the cylindrical tube 11, the arc plate 10, which is fixedly connected to the push rod 25, will move away from the take-up roller 9. When the drive assembly releases the push force on the push rod 25, the push rod 25 will move closer to the take-up roller 9 under the action of the tension spring fixedly connected to the convex rod 27, thereby realizing the back-and-forth movement of the arc plate 10.

[0047] The drive assembly includes an anti-slip plate 22, a rotating disk 23, a rotating rod 24, and an arc-shaped push plate 36. The baffle plate 12 on the top of the take-up roller 9 is movably covered at the port of the columnar slot 33, and the bottom of the baffle plate 12 at the port of the columnar slot 33 is fixedly provided with an anti-slip plate 22. The anti-slip plate 22 is embedded at the port of the columnar slot 33. The bottom of the anti-slip plate 22 is fixedly connected to the rotating rod 24. The rotating disk 23 is fixedly provided on the rotating rod 24. The outer periphery of the rotating disk 23 is provided with an arc-shaped push plate 36. The arc-shaped push plate 36 is arranged in a ring around the axis of the rotating disk 23 on the outer periphery of the rotating disk 23.

[0048] In actual operation, the upper end of the cylindrical slot 33 is first sealed by the baffle 12. At this time, the anti-slip plate 22 is embedded in the end of the cylindrical slot 33, and the arc-shaped push plate 36 on the rotating disk 23 is in a position away from the push rod 25. Then, the baffle 12 is rotated at a certain angle, so that the side of the arc-shaped push plate 36 away from the rotating disk 23 pushes the push rod 25 away from the rotating rod 24, so that the arc-shaped plate 10 moves away from the take-up roller 9. When it is necessary to disassemble the wire bundle wrapped around the outside of the arc-shaped plate 10, it can be done at this time. Next, rotate the baffle 12 so that the arc-shaped push plate 36 on the rotating disk 23 rotates to a position away from the push rod 25. At this time, the push rod 25 will move towards the rotating disk 23 under the action of the tension spring fixedly connected to the protruding rod 27, thereby driving the arc-shaped plate 10 to move towards the take-up roller 9, so that there is a gap between the wire harness and the arc-shaped plate 10. At this time, pull the baffle 12 upward to release the restriction of the baffle 12 on the wire harness at the top of the take-up roller 9, so that the bundled wire harness can be directly detached from the top of the arc-shaped plate 10.

[0049] It should be noted that when the arc-shaped push plate 36 on the rotating disk 23 contacts the push rod 25, and the arc-shaped plate 10 is positioned away from the take-up roller 9, the through slot 13 on the baffle 12 corresponds to the position of the inset slot 26. When the take-up roller 9 rotates, the baffle 12 rotates synchronously with the take-up roller 9 to prevent the ends of the binding rope 34 from being pulled. To prevent relative rotation between the baffle 12 and the take-up roller 9, the anti-slip plate 22 can be made of elastic material such as rubber, so that it can be elastically supported at the upper end of the columnar slot 33. Alternatively, spring pins or other components with limiting functions can be set on the outer periphery of the anti-slip plate 22.

[0050] The clamping assembly includes a clamping plate 15, on which a plurality of clamping slots 16 are provided. The number of clamping slots 16 is equal to the number of wire embedding slots 26. An elastic pad 17 is fixedly provided on the inner wall of the clamping slot 16 to elastically compress the binding rope 34.

[0051] Specifically, the end of the binding rope 34 can be locked inside the clamping slot 16, and the elastic pad 17 can elastically press the binding rope 34 to prevent the end of the binding rope 34 from falling off and winding inside the wire harness, and also to prevent the binding rope 34 from winding on the shaft of the drive motor 18 and affecting the rotation of the drive motor 18.

[0052] The clamping slot 16 has a V-shaped structure, and the port of the clamping slot 16 faces the outside of the clamping plate 15. The elastic pad 17 has a V-shaped structure that matches the clamping slot 16.

[0053] Since the binding ropes 34 used by different factories are not of equal thickness, the clamping slot 16 is designed as a V-shaped structure. The inside of the clamping slot 16 can clamp binding ropes 34 of different thicknesses. The thicker binding ropes 34 are clamped near the port of the elastic pad 17, while the thinner binding ropes 34 need to be embedded inside the elastic pad 17 away from the port to be clamped, which makes it more versatile.

[0054] Furthermore, the inner wall of the elastic pad 17 has a wave-like structure with protrusions and recesses, and the protrusions on the two opposite inner walls of the elastic pad 17 are in a one-to-one correspondence.

[0055] The wavy structure of the inner wall of the elastic pad 17 increases the frictional resistance between the binding rope 34 and the inner wall of the elastic pad 17, thereby preventing the binding rope 34 from detaching from the interior of the elastic pad 17. At the same time, the recessed part on the clamping slot 16 has a larger contact area with the binding rope 34. Compared with the contact with the planar structure of the elastic pad 17, the increased contact area increases the frictional resistance between the inner wall of the elastic pad 17 and the binding rope 34, further preventing the binding rope 34 from falling out of the interior of the elastic pad 17.

[0056] To facilitate the fitting of the pressing sleeve 3 onto the outside of the second pressing roller 2, a slight gap will inevitably exist between the pressing sleeve 3 and the second pressing roller 2. Consequently, when the pressing sleeve 3 shakes, the central axes of the pressing sleeve 3 and the second pressing roller 2 will not coincide. As a result, the gap between the first pressing roller 1 and the pressing sleeve 3 will change during the rotation of the second pressing roller 2, leading to uneven thickness of the flat copper wire. To avoid this problem, an annular receiving groove 30 is provided inside the second pressing roller 2 at a position corresponding to the pressing sleeve 3. Inside one set of the annular receiving groove 30, there are several sets of electric push rods 31 arranged in an equidistant annular pattern around the axis of the second pressing roller 2. The fixed end of the electric push rod 31 is fixedly connected to the bottom of the annular receiving groove 30, and the free end of the electric push rod 31 is braced in the insertion groove 35 on the inner wall of the pressing sleeve 3. The electric push rods 31 are distributed radially along the second pressing roller 2.

[0057] In actual operation, when the pressing sleeve 3 is fitted outside the second pressing roller 2, the electric push rod 31 inside the annular receiving groove 30 can be started simultaneously. The electric push rod 31 will be simultaneously braced against the inner wall of the pressing sleeve 3, thereby making the central axis of the pressing sleeve 3 coincide with the central axis of the second pressing roller 2. This ensures that the gap between the first pressing roller 1 and the pressing sleeve 3 remains consistent during the rotation of the first pressing roller 1 and the second pressing roller 2, avoiding uneven thickness of the flat copper wire. At the same time, since the free end of the electric push rod 31 is located in the insertion groove 35 on the inner wall of the pressing sleeve 3, it can prevent the pressing sleeve 3 from rotating relative to the second pressing roller 2, thus avoiding affecting the transmission of copper wire by the first pressing roller 1 and the pressing sleeve 3.

[0058] The arc plate 10 has a hook groove 32 on the side facing the take-up roller 9. The bottom of the hook groove 32 has a V-shaped structure, and the direction of the hook groove 32 is parallel to the axis of the take-up roller 9.

[0059] Specifically, when it is necessary to fix the flattened copper wire end to the arc plate 10, the end of the copper wire can be bent, and then the bent part of the copper wire can be inserted into the hook groove 32. The operation is convenient and solves the problem of fixing the end of the round copper wire to the arc plate 10.

[0060] The first pressing roller 1 and the second pressing roller 2 are both movably mounted on the mounting platform 6. The bottom of the first pressing roller 1 and the second pressing roller 2 are both fixedly provided with spur gears 5, and the two sets of spur gears 5 mesh with each other. The rotating shaft at the bottom of the first pressing roller 1 is connected to the drive motor 18. The take-up roller 9 and the unwinding roller 8 are both movably mounted on the mounting platform 6, and the rotating shaft at the bottom of the take-up roller 9 is connected to the drive motor 18.

[0061] Meanwhile, in order to prevent the clamping plate 15 on the baffle 12 at the bottom of the take-up roller 9 from affecting the rotation of the baffle 12, a recessed area 14 is provided on the mounting platform 6.

[0062] The bottom of the spherical gear 5, the bottom of the feed roller 8, and the bottom of the baffle 12 at the bottom of the take-up roller 9 are all fixedly provided with limiting rings 19. The limiting rings 19 are slidably connected to the annular guide groove 20 on the upper surface of the mounting platform 6, and the bottom of the limiting rings 19 is provided with ball bearings 21.

[0063] Specifically, the sliding connection between the limiting ring 19 and the annular guide groove 20 can limit the rotation of the first pressing roller 1, the second pressing roller 2, the unloading roller 8, and the take-up roller 9, making their rotation more stable. At the same time, the ball bearing 21 can greatly reduce the frictional resistance between the limiting ring 19 and the annular guide groove 20, thereby reducing the energy consumption of the drive motor 18.

[0064] Working Principle: In actual operation, the round copper wire released from the feed roller 8 is flattened as it passes between the first pressing roller 1 and the second pressing roller 2. The flattened copper wire is then wound around the outside of the "quasi-cylindrical tube" formed by the arc-shaped plates 10. Since the second pressing roller 2 is fitted with a pressing sleeve 3, the gap between the first pressing roller 1 and the second pressing roller 2 can be changed by replacing the pressing sleeve 3 with different sizes, thereby pressing out copper wires of different thicknesses. For example, if the outer diameter of the pressing sleeve 3 is larger, the gap between the first pressing roller 1 and the pressing sleeve 3 is smaller, and the thickness of the pressed copper wire is smaller. Similarly, when the outer diameter of the pressing sleeve 3 is smaller, the gap between the first pressing roller 1 and the pressing sleeve 3 is smaller. The gap formed between them is relatively large, and the thickness of the copper wire after being rolled by the first rolling roller 1 and the rolling sleeve 3 is relatively large. The protruding edges 4 at both ends of the rolling sleeve 3 play a role in guiding and limiting the copper wire. In practical applications, multiple rolling sleeves 3 of the same size can be fitted on the second rolling roller 2, so that multiple rolls of copper wire can be rolled and formed at the same time. Alternatively, multiple rolling sleeves 3 of different sizes can be fitted on the outside of the second rolling roller 2, so that multiple sets of flat copper wires of different thicknesses can be rolled at the same time. It should be noted that the distance between the two sets of protruding edges 4 on the rolling sleeve 3 should match the gap between the first rolling roller 1 and the rolling sleeve 3. That is, when a round copper wire of a fixed diameter is flattened to a certain thickness, its width is also fixed.

[0065] Furthermore, the take-up roller 9 is provided with an arc-shaped plate 10 that can move closer to or further away from it. When the arc-shaped plate 10 is in a position away from the take-up roller 9, the flat copper wire is wound around the outside of the "cylindrical-like tube" formed by the arc-shaped plate 10. After the winding is finished, the arc-shaped plate 10 can be controlled to move closer to the take-up roller 9, so that there is a gap between the wound wire bundle and the arc-shaped plate 10, making it convenient to peel the wire bundle off the outside of the arc-shaped plate 10.

[0066] Meanwhile, the first pressing roller 1, the second pressing roller 2, the unloading roller 8, and the take-up roller 9 in this invention are all placed vertically. The vertical placement of the second pressing roller 2 makes it easier to replace the pressing sleeve 3 on the second pressing roller 2, while the vertical placement of the take-up roller 9 makes it easier to remove the wound wire bundle outside the arc plate 10. Therefore, compared with the traditional horizontally placed rollers, this invention does not require detaching one end of the second pressing roller 2 or one end of the take-up roller 9 from the mounting frame when replacing the pressing sleeve 3 or removing the wire bundle. This not only saves time and effort but also makes the operation convenient. At the same time, it can also effectively prevent the outside of the first pressing roller 1, the second pressing roller 2, the unloading roller 8, and the take-up roller 9 from being covered with dust.
