Description

Technical Field

[0001] This invention belongs to the technical field of deep processing of metal wires, specifically, it relates to a metal wire drawing device for metal mesh. Background Technology

[0002] The fundamental purpose of metal wire drawing is to process metal raw materials (wires or coarse wires) into fine wire products with specific dimensions, shapes, surface conditions, and mechanical properties through plastic deformation. The drawing process is a cold (or warm) working process, which significantly alters the internal structure and properties of the metal. During drawing, the metal grains are elongated and broken, and the dislocation density increases sharply, producing a "work hardening" effect, thereby significantly improving the strength, hardness, and rigidity of the metal wire. Drawing also causes the grains to align in a specific direction, resulting in different properties in the longitudinal (drawing direction) and transverse directions, a characteristic that needs to be utilized in certain applications.

[0003] Before wire drawing, the metal wire roll needs to be unwound and then immersed in lubricating oil. Afterward, the wire is gradually thinned using a drawing device, and finally wound onto a take-up drum. During the unwinding process, the wire is generally passively unwound; that is, the wire is subjected to a continuous traction force at the point in front of the drawing device by the drawing device and the take-up drum. Under this traction force, the wire roll gradually unwinds. However, during this process, the wire roll often unwinds too slowly or too quickly, making it prone to scattering and knotting. Furthermore, when immersed in lubricating oil, the wire typically passes through the immersion tank in a single linear strand. This results in a short contact time between the lubricating oil and the wire, preventing the lubricating oil from fully adhering to the wire surface and failing to effectively remove impurities, thus affecting subsequent wire drawing processes. Moreover, lubricating oil has a cooling effect. After the metal wire is heated, the lubricating oil in the immersion bath cannot fully anneal the metal wire, which in turn affects the performance of the metal wire after subsequent drawing. Summary of the Invention

[0004] This invention provides a metal wire drawing device for metal mesh, which ensures that the unwound metal wire remains taut, avoids scattering and knotting, and increases the contact time between the metal wire and the lubricating oil, so that the lubricating oil fully adheres to the surface of the metal wire and ensures that the impurities attached to the metal wire are fully removed, thereby improving the performance of the drawn metal wire.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A wire drawing device for metal mesh includes a self-unwinding mechanism, a wire guiding mechanism, a multi-stage winding immersion mechanism, and a wire drawing and winding mechanism arranged sequentially along the processing direction of the wire. A self-weight tensioning mechanism is installed on the wire guiding mechanism, and the wire passes through the self-weight tensioning mechanism during the process of passing through the wire guiding mechanism.

[0007] Furthermore, the self-unwinding mechanism includes a mounting base on which a first power motor is detachably mounted at the upper end. A yarn spool is placed on the mounting base. A vertical rod is movably inserted into the yarn spool along its axis from the upper end of the yarn spool. The lower end of the vertical rod is coaxially connected to the output shaft of the first power motor. A radial rod is connected to the upper end of the vertical rod. The radial rod extends outward along the radial direction of the yarn spool. A guide ring is constructed at the end of the radial rod away from the vertical rod.

[0008] Furthermore, the wire guiding mechanism includes a vertical arm with its lower end mounted on the ground, a horizontal arm constructed at the upper end of the vertical arm, a wire transition assembly mounted at the end of the horizontal arm away from the vertical arm, a first wire guide wheel and a second wire guide wheel spaced apart along the length of the horizontal arm, an inclined arm and an elastic telescopic arm hinged to the vertical arm, the end of the elastic telescopic arm away from the vertical arm being hinged to the inclined arm, and a self-weight tensioning mechanism mounted at the end of the inclined arm away from the vertical arm.

[0009] Furthermore, the wire transition assembly includes a vertically arranged conical spring-shaped guide tip with its large-diameter end facing downwards. Connecting rings are coaxially fixed to the large-diameter end and the small-diameter end of the guide tip, respectively. The small-diameter end of the guide tip is fixedly connected to the lower end of the vertical guide tube, and the upper end of the vertical guide tube is detachably connected to the horizontal arm via an adapter lug.

[0010] Furthermore, the self-weight tensioning mechanism includes a mounting plate rotatably connected to the inclined arm via an adapter shaft. Multiple elastic tension wire assemblies are uniformly constructed on the mounting plate along its circumference. The metal wires wrap around the mounting plate along its circumference and pass through each elastic tension wire assembly at least once.

[0011] Furthermore, a second power motor is installed on the inclined arm, and the output shaft of the second power motor is coaxially connected to the adapter shaft.

[0012] Furthermore, the elastic tensioning assembly includes a radial guide rail extending outward along the radial direction of the mounting plate, a sliding block slidably connected to the radial guide rail, a connecting shaft parallel to the axis of the adapter shaft connected to the sliding block, a tensioning wheel coaxially rotatably connected to the connecting shaft, and an externally threaded adjusting tube extending along the radial guide rail threadedly connected to the radial guide rail. The externally threaded adjusting tube is connected to the connecting shaft via a connecting rod elastically connected to it.

[0013] Furthermore, the multi-stage winding immersion mechanism includes an immersion tank with its upper end in an open state. An inlet wheel and an outlet wheel are respectively installed at the upper end of the immersion tank and at both ends along the wire conveying direction. Multiple impeller-type wire guide rollers are rotatably installed inside the immersion tank along its length direction. The multiple impeller-type wire guide rollers are driven by a drive assembly installed on the outside of the immersion tank. The wire passes through each impeller-type wire guide roller in sequence and is wound around each impeller-type wire guide roller.

[0014] Furthermore, the impeller-type guide roller includes a roller-shaped body with a liquid guiding cavity, liquid guiding holes are uniformly opened on the circumferential surface of the roller-shaped body, a plurality of impeller blades are uniformly constructed along its circumferential direction on the outer circumferential surface of the roller-shaped body, and a liquid guiding pipe and a mounting shaft are respectively constructed at both axial ends of the roller-shaped body. The liquid guiding pipe and the mounting shaft are respectively rotatably connected to the corresponding side wall of the immersion tank, and the liquid guiding pipe is rotatably connected to the liquid inlet pipe or the liquid outlet pipe, and the mounting shaft is drively connected to the drive assembly.

[0015] Furthermore, the wire drawing and winding mechanism includes a vertical base whose lower end is fixed to the ground via a fixing lug. A winding roller, a first wire wheel, and a second wire wheel are sequentially rotatably connected to the vertical base in a vertical direction. A vertically extending strip hole is provided in the upper part of the vertical base. The shaft of the second wire wheel moves through the strip hole. A third power motor is mounted on the vertical base via a fixing plate. A fourth power motor is movably connected to the vertical base via a movable base. A vertical drive component is connected between the fixing plate and the movable base. The output shaft of the third power motor is connected to the shaft of the first wire wheel, and the output shaft of the fourth power motor is connected to the shaft of the second wire wheel. The fourth power motor is connected to the insertion rod of the winding roller via a belt pulley drive.

[0016] The present invention, by employing the aforementioned structure, achieves a technological advancement compared to existing technologies in the following ways: The invention utilizes a self-unwinding mechanism to unwind the metal wire at a predetermined speed, thereby avoiding excessively slow or fast unwinding and effectively preventing the metal wire from becoming overly taut or slack. After entering the wire guide mechanism, the wire guides the wire, allowing it to smoothly enter the multi-stage winding immersion mechanism. During the wire's passage through the guide mechanism, the wire passes through a self-weight tensioning mechanism, which tensions the wire using gravity and elasticity, ensuring the wire enters the multi-stage winding immersion mechanism in a taut state. Within the multi-stage winding immersion mechanism, the wire is in a multi-stage winding configuration. Furthermore, when controlling the operation of the multi-stage winding immersion mechanism, it simultaneously winds and unwinds the wire, thus achieving a stable introduction and exit of the wire into and out of the multi-stage winding immersion mechanism. Furthermore, because the metal wires in the multi-stage winding immersion mechanism are wound in multiple stages, the metal wires are in full contact with the lubricating oil within the mechanism. After passing through the multi-stage winding immersion mechanism, the metal wires enter the drawing and winding mechanism. The drawing force of the drawing and winding mechanism is controlled to obtain metal wires of a corresponding radial length, and the drawn metal wires are then wound up. In summary, this invention effectively ensures that the unwound metal wires remain taut, preventing the wires from scattering or knotting. It also increases the contact time between the metal wires and the lubricating oil, allowing the lubricating oil to fully adhere to the surface of the metal wires and ensuring that impurities adhering to the wires are fully removed, thus improving the performance of the drawn metal wires.

Detailed Implementation

[0036] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0037] This invention discloses a metal wire drawing device for metal mesh, such as... Figure 1-16As shown, the device includes a self-unwinding mechanism 100, a wire guide mechanism 300, a multi-stage winding immersion mechanism 500, and a wire drawing and winding mechanism 600 arranged sequentially along the processing direction of the metal wire 700. A self-weight tensioning mechanism 400 is installed on the wire guide mechanism 300, and the metal wire 700 passes through the self-weight tensioning mechanism 400 during its passage through the wire guide mechanism 300. The working principle and advantages of this invention are: the self-unwinding mechanism 100 unwinds the metal wire 700 at a predetermined speed, thereby avoiding unwinding that is too slow or too fast, and thus effectively preventing the metal wire 700 from being over-tensioned or over-slack. After the metal wire 700 enters the wire guide mechanism 300, the wire guide mechanism 300 guides the metal wire 700, allowing it to smoothly enter the multi-stage winding immersion mechanism 500. During the passage of the metal wire 700 through the wire guide mechanism 300, the metal wire 700 is tensioned by a self-weight tensioning mechanism 400 using gravity and elasticity, ensuring that the metal wire 700 enters the multi-stage winding immersion mechanism 500 in a taut state. Within the multi-stage winding immersion mechanism 500, the metal wire 700 is in a multi-stage wound state. Furthermore, when controlling the operation of the multi-stage winding immersion mechanism 500, it simultaneously winds and unwinds the metal wire 700, thereby achieving a steady introduction and exit of the metal wire 700 into and out of the multi-stage winding immersion mechanism 500. Furthermore, because the metal wire 700 within the multi-stage winding immersion mechanism 500 is in a multi-stage winding configuration, it ensures sufficient contact between the metal wire 700 and the lubricating oil within the mechanism. After passing through the multi-stage winding immersion mechanism 500, the metal wire 700 enters the drawing and winding mechanism 600. The drawing force of the drawing and winding mechanism 600 is controlled to obtain a metal wire 700 of corresponding radial length, and the drawn metal wire 700 is then wound up. In summary, this invention effectively ensures that the unwound metal wire 700 remains taut, preventing it from scattering or knotting. It also increases the contact time between the metal wire 700 and the lubricating oil, allowing the lubricating oil to fully adhere to the surface of the metal wire 700 and ensuring that impurities adhering to the metal wire 700 are fully removed, thus improving the performance of the drawn metal wire 700.

[0038] As a preferred embodiment of the present invention, such as Figure 3-5As shown, the self-unwinding mechanism 100 includes a mounting base 103, a first power motor 104, a yarn spool 101, a vertical rod 106, and a radial rod 108. The first power motor 104 is detachably mounted on the upper end of the mounting base 103, the yarn spool 101 is placed on the mounting base 103, and the first power motor 104 extends into the yarn spool 101 from its lower end. A movable hole 102 extending along its axis is provided on the spool 101. The lower end of the vertical rod 106 is movably inserted into the spool 101 through the movable hole 102 along the axis of the spool 101 from the upper end of the spool 101. A plug interface 105 is provided at the upper end of the output shaft of the first power motor 104. A plug connector 107 is fixed at the lower end of the vertical rod 106 and is inserted into the plug interface 105. The axes of the output shaft of the first power motor 104, the vertical rod 106, and the spool 101 coincide. In this embodiment, one end of the radial rod 108 is fixedly connected to the upper end of the vertical rod 106. The radial rod 108 extends outward along the radial direction of the spool 101. A guide ring 109 is constructed at the end of the radial rod 108 away from the vertical rod 106. The metal wire 700 unwound from the spool 101 passes through the guide ring 109. The working principle and advantages of this embodiment are as follows: This embodiment controls the operation of the first power motor 104 to drive the vertical rod 106 to rotate along the axis of the wire spool 101, thereby driving the radial rod 108 to rotate; during the rotation of the radial rod 108, the metal wire 700 wound on the wire spool 101 is gradually unwound, thereby effectively avoiding the situation where the metal wire 700 is unwound too slowly or too quickly, and also preventing the metal wire 700 from being unwound in a spiral shape and causing knots.

[0039] As a preferred embodiment of the present invention, such as Figure 2 , 6As shown, the wire guiding mechanism 300 includes a vertical arm 301, a horizontal arm 302, a first wire guide wheel 303, a second wire guide wheel 304, an inclined arm 305, and an elastic telescopic arm. The lower end of the vertical arm 301 is mounted on the ground, and the horizontal arm 302 is constructed at the upper end of the vertical arm 301. A wire transition assembly 200 is mounted at the end of the horizontal arm 302 away from the vertical arm 301. The first wire guide wheel 303 and the second wire guide wheel 304 are spaced apart on the horizontal arm 302 along its length. One end of the inclined arm 305 is hinged to the vertical arm 301, and one end of the elastic telescopic arm is hinged to the inclined arm 305. The end of the elastic telescopic arm away from the vertical arm 301 is also hinged to the inclined arm 305. A self-weight tensioning mechanism 400 is mounted at the end of the inclined arm 305 away from the vertical arm 301. The elastic telescopic arm of this embodiment includes an assembly tube 306 and an assembly rod 307. One end of the assembly rod 307 extends movably into the assembly tube 306. A first connecting spring is installed inside the assembly tube 306. The two ends of the first connecting spring are connected to the inner wall of the assembly tube 306 and the end of the assembly rod 307, respectively. The end of the assembly tube 306 away from the assembly rod 307 is hinged to the vertical arm 301, and the end of the assembly rod 307 away from the first connecting spring is hinged to the inclined arm 305. After being unwound by the self-unwinding mechanism 100, the metal wire 700 passes sequentially through the wire transition assembly 200, the first guide wheel 303, the self-weight tensioning mechanism 400, and the second guide wheel 304. The wire transition assembly 200 can effectively restrict the metal wire 700 and prevent the metal wire 700 from swinging. The self-weight tensioning mechanism 400 can effectively tighten the metal wire 700, so that the metal wire 700 exiting from the second guide wheel 304 is stably led out in a taut state. When the metal wire 700 is in a relaxed state at the position of the first guide wheel 303 and the second guide wheel 304, the gravity-type tensioning mechanism 400 moves downward a certain distance under the action of gravity. At the same time, the inclined arm 305 swings downward, and the elastic telescopic arm extends and retracts accordingly, thereby gradually tensioning the metal wire 700. When the metal wire 700 is in an over-tensioned state at the position of the first guide wheel 303 and the second guide wheel 304, the tension of the metal wire 700 acts on the gravity-type tensioning mechanism 400, causing the gravity-type tensioning mechanism 400 to move upward. At the same time, the inclined arm 305 swings upward, and the elastic telescopic arm extends and retracts accordingly, thereby gradually releasing the over-tensioned state of the metal wire 700 and ensuring that the metal wire 700 is stably conveyed under the predetermined tension.

[0040] As a preferred embodiment of the present invention, such as Figure 2 , 6As shown, the wire transition assembly 200 includes a guide nozzle 201, a vertical guide tube 202, and an adapter ear 203. The guide nozzle 201 is a vertically positioned conical spring-shaped structure with its large-diameter end facing downwards. Connecting rings are coaxially fixed to both the large-diameter and small-diameter ends of the guide nozzle 201, ensuring smooth operation at both ends. The small-diameter end of the guide nozzle 201 is fixedly connected to the lower end of the vertical guide tube 202, while the upper end of the vertical guide tube 202 is detachably connected to the horizontal arm 302 via the adapter ear 203. The metal wire 700 is unwound by the self-unwinding mechanism 100 and enters the vertical guide tube 202 through the guide nozzle 201. The guide nozzle 201 and the vertical guide tube 202 prevent the metal wire 700 from swaying or vibrating as it passes through the first guide wheel 303, thus preventing the metal wire 700 from detaching from the first guide wheel 303.

[0041] As a preferred embodiment of the present invention, such as Figure 6-10 As shown, the self-weight tensioning mechanism 400 includes a mounting plate 401, a connecting shaft 411, and multiple elastic tensioning wire assemblies. The mounting plate 401 and the connecting shaft 411 are coaxially arranged, with the connecting shaft 411 rotatably connected to the end of the inclined arm 305 away from the vertical arm 301. The multiple elastic tensioning wire assemblies are evenly constructed on the mounting plate 401 circumferentially. Metal wires 700 are wound around the mounting plate 401 circumferentially, with at least one turn, and each turn of metal wire 700 is connected to a specific elastic tensioning wire assembly. During the passage of the self-weight tensioning mechanism 400, the metal wires 700 press against the individual elastic tensioning wire assemblies. When the wire 700 is over-tensioned, the force exerted by the wire 700 on each elastic tensioning component increases, causing the elastic tensioning component to deform and store energy. At the same time, the tension force on the wire 700 is transmitted to the mounting plate 401, causing the mounting plate 401 to be driven to rotate, i.e., the mounting plate 401 rotates passively. Simultaneously, the inclined arm 305 and the elastic telescopic arm undergo corresponding position changes and elastic extension and contraction, which can effectively reduce the tension of the wire 700. Furthermore, due to the rotation of the mounting plate 401, the wire 700 can smoothly pass through the self-weight tensioning mechanism 400, avoiding the situation where the wire 700 gets stuck in the self-weight tensioning mechanism 400 due to excessive tension. In order to improve the smoothness of the metal wire 700 passing through the self-weight tensioning mechanism 400, the following measures are taken in this embodiment: a second power motor 412 is installed on the inclined arm 305, and the output shaft of the second power motor 412 is coaxially connected to the adapter shaft 411; by controlling the action of the second power motor 412, it drives the mounting plate 401 to rotate, and the mounting plate 401 drives all the elastic tensioning components to rotate along the axis of the mounting plate 401, so that the part where the metal wire 700 is wound can pass smoothly, that is, the mounting plate 401 rotates actively.

[0042] As a preferred embodiment of the present invention, such as Figure 9 , 10As shown, the elastic tensioning assembly includes a radial guide rail 402, a sliding block 403, a tensioning wheel 405, an external threaded adjusting tube 407, and a connecting rod 409. The radial guide rail 402 extends radially outward along the mounting plate 401. The sliding block 403 is slidably connected to the radial guide rail 402. A connecting shaft 404 is connected to the sliding block 403, and the axis of the connecting shaft 404 is parallel to the axis of the adapter shaft 411. The tensioning wheel 405 is coaxially mounted on the connecting shaft 404, and the tensioning wheel 405 is rotatably connected to the connecting shaft 404. In this embodiment, a mounting lug 406 is constructed at the end of the radial guide rail 402 away from the mounting plate 401. An external threaded adjusting tube 407 is threadedly connected to the mounting lug 406 and extends along the guide of the radial guide rail 402. One end of the connecting rod 409 is movably inserted into the external threaded adjusting tube 407. A second connecting spring is installed inside the external threaded adjusting tube 407. The two ends of the second connecting spring are respectively connected to the inner wall of the external threaded adjusting tube 407 and the end of the connecting rod 409. A connecting sleeve 410 is fixed at the other end of the connecting rod 409. The connecting sleeve 410 is fitted over the connecting shaft 404 and is fixedly connected to the connecting shaft 404. An operating head 408 is constructed at the end of the external threaded adjusting tube 407 away from the connecting shaft 404. Furthermore, to prevent the self-weight tensioning mechanism 400 from being too heavy and unable to change position when the tension of the wire 700 changes, or from causing the wire 700 to break, the following measures are taken: the mounting plate 401, radial guide rail 402, sliding block 403, and tensioning wheel 405 are all made of lightweight polyethylene, lightweight alloy, or carbon fiber. The working principle and advantages of this embodiment are as follows: as the coiled wire 700 passes through each elastic tensioning assembly, the second connecting spring elastically drives the connecting rod 409 to move radially outward along the mounting plate 401, causing the tensioning wheel 405 to elastically tension the wire 700, thereby ensuring that the wire 700 remains taut when passing through the self-weight tensioning mechanism 400; when the tension of the wire 700 changes, the second connecting spring will undergo corresponding elastic deformation, so that the tensioning wheel 405 always externally tensions the wire 700. Furthermore, as the metal wire 700 passes through the various elastic tensioning components, the tensioning wheel 405 rotates, reducing wear on the metal wire 700. In this embodiment, the external threaded adjusting tube 407 can be rotated to move radially along the mounting plate 401, thereby driving the sliding block 403 and the tensioning wheel 405 to move radially along the mounting plate 401 via the connecting rod 409. This adjusts the radial length of the 700 turns of the metal wire 700 wrapped around the self-weight tensioning mechanism 400, thus adapting to the tension of metal wires 700 of different thicknesses. More turns result in better tension, but also greater resistance. When the number of turns exceeds a certain limit, the metal wire 700 is prone to over-tensioning. Therefore, the optimal number of turns is 2-3.

[0043] As a preferred embodiment of the present invention, such as Figure 11-14As shown, the multi-stage winding immersion mechanism 500 includes an immersion tank 501, an inlet wheel 502, an outlet wheel 503, and multiple impeller-type guide rollers 504. The upper end of the immersion tank 501 is open and filled with lubricating oil. The inlet wheel 502 and outlet wheel 503 are respectively installed at the upper end of the immersion tank 501, and are located at both ends along the conveying direction of the metal wire 700. The multiple impeller-type guide rollers 504 are rotatably installed within the immersion tank 501 along its length. A drive assembly is installed on the outside of the immersion tank 501, driving each impeller-type guide roller 504 to rotate. The metal wire 700 passes sequentially through each impeller-type guide roller 504 and is wound around each impeller-type guide roller 504. In this embodiment, a drive assembly is used to drive all impeller-type wire guide rollers 504 to rotate synchronously and in the same direction. During the rotation, each impeller-type wire guide roller 504 winds up one end of the metal wire 700 and unwinds the other end of the metal wire 700. In this process, the metal wire 700 is stably passed through the immersion tank 501, and the length of the metal wire 700 in the immersion tank 501 is increased, thereby increasing the contact time between the metal wire 700 and the lubricating oil, and ensuring that the metal wire 700 and the lubricating oil have full contact without any dead angles. The impeller-type guide roller 504 in this embodiment has the following structure: It includes a roller-shaped body 5041 with a liquid guiding cavity 5042. Limiting disks 5045 are constructed at both axial ends of the roller-shaped body 5041. The metal wire 700 is wound around the area between the two limiting disks 5045, thus preventing the metal wire 700 from detaching from the roller-shaped body 5041. Liquid guiding holes 5043 are uniformly formed on the circumferential surface of the roller-shaped body 5041, connecting the liquid guiding cavity 5042 to the immersion tank 501. In this embodiment, multiple impeller blades 5044 are constructed on the outer circumferential surface of the roller-shaped body 5041. These impeller blades 5044 are uniformly arranged along the circumference of the roller-shaped body 5041, and each impeller blade 5044 is made of an elastic metal material. A liquid guide pipe 5046 and a mounting shaft 5047 are respectively constructed at both axial ends of the roller-shaped body 5041. The liquid guide pipe 5046 is connected to the liquid guide cavity 5042, and the liquid guide pipe 5046 and the mounting shaft 5047 are respectively rotatably connected to the corresponding side wall of the immersion tank 501.In this embodiment, there are two impeller-type guide rollers 504. The liquid guide pipe 5046 of one impeller-type guide roller 504 is rotatably connected to the end of the liquid inlet pipe 505, and the liquid guide pipe 5046 of the other impeller-type guide roller 504 is rotatably connected to the end of the liquid outlet pipe 506. An intermediate tank is provided between the liquid inlet pipe 505 and the liquid outlet pipe 506. The intermediate tank is filled with lubricating oil. The oil outlet of the intermediate tank is connected to the inlet end of the pressure pump. A filter is provided between the intermediate tank and the pressure pump to filter impurities in the lubricating oil. The outlet end of the pressure pump is connected to the liquid inlet pipe 505. In this embodiment, the pressure pump is controlled to pump lubricating oil from the intermediate tank into one of the impeller-type wire guide rollers 504 through the inlet pipe 505. The oil then flows through the guide hole 5043 on the impeller-type wire guide roller 504 into the immersion tank 501. During this process, the lubricating oil impacts the metal wire 700 wound on the impeller-type wire guide roller 504, causing impurities on the metal wire 700 to detach quickly. Simultaneously, lubricating oil exits the immersion tank 501 through the guide hole 5043 on the other impeller-type wire guide roller 504. During this process, the flowing lubricating oil impacts the metal wire 700 on the impeller-type wire guide roller 504, also achieving the effect of removing impurities from the metal wire 700. Afterward, the lubricating oil enters the intermediate tank through the outlet pipe 506, thus forming a lubricating oil circulation, ensuring that the entire lubrication and impurity removal process remains continuous. In this embodiment, each mounting shaft 5047 is connected to a drive assembly. Specifically, the drive assembly includes a drive motor 507, which is coaxially connected to one of the mounting shafts 5047. A drive sprocket 508 is mounted on each mounting shaft 5047, and these two drive sprockets 508 are connected by a drive chain 509. Thus, by controlling the operation of the drive motor 507, it drives the two impeller-type guide rollers 504 to rotate synchronously and in the same direction via the sprockets, thereby achieving the simultaneous winding and unwinding of the metal wire 700. In this embodiment, because the impeller blades 5044 are made of elastic metal, during the winding and unwinding process of the metal wire 700, the elastic impeller blades 5044 elastically expand outwards, ensuring that the metal wire 700 remains taut when the tension changes. Furthermore, during the rotation of the impeller-type guide roller 504, the lubricating oil is in a turbulent state under the action of the impeller blade 5044, which prevents impurities from depositing at the bottom of the immersion tank 501, allowing the impurities to enter the filter with the lubricating oil and be filtered out, thus reducing the frequency of cleaning the immersion tank 501.

A fixing lug 611 is constructed at the lower end of the vertical base 601, which is fixed to the ground. An assembly shaft 610 is rotatably connected to the lower part of the vertical base 601, and an insertion rod 612 is fixed to one end of the assembly shaft 610. The winding roller 613, the first wire wheel 602, and the second wire wheel 603 are arranged vertically upwards at intervals. An insertion hole 614 is opened on the winding roller 613 along its axis, and the insertion rod 612 is movably inserted into the winding roller 613 through the insertion hole 614. Both the first wire wheel 602 and the second wire wheel 603 are rotatably connected to the vertical base 601. In this embodiment, a vertically extending strip-shaped hole 608 is provided on the upper part of the vertical base 601. The shaft of the second wire wheel 603 movably passes through the strip-shaped hole 608. The third power motor 604 is mounted on the vertical base 601 via a fixing plate 606. The fourth power motor 605 is movably connected to the vertical base 601 via a movable base 607. A vertical drive component 609 is connected between the fixing plate 606 and the movable base 607. The vertical drive component 609 is generally an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. A pressure sensor is installed on the cylinder rod of the vertical drive component 609. The output shaft of the third power motor 604 is connected to the shaft of the first wire wheel 602, and the output shaft of the fourth power motor 605 is connected to the shaft of the second wire wheel 603. The fourth power motor 605 is connected to the insertion rod 612 of the take-up roller 613 via a belt pulley drive. Specifically, transmission wheels 615 are respectively mounted on the shaft of the first wire wheel 602 and the mounting shaft 610, and these two transmission wheels 615 are connected by a transmission belt 616. The working principle and advantages of this embodiment are as follows: the metal wire 700 is wound around the first wire wheel 602 and the second wire wheel 603 multiple times and then wound onto the take-up roller 613. By controlling the third power motor 604 and the fourth power motor 605 to operate synchronously, the first wire wheel 602, the second wire wheel 603 and the take-up roller 613 rotate synchronously and in the same direction, so that the metal wire 700 is wound onto the take-up roller 613 after passing through the first wire wheel 602 and the second wire wheel 603; and by controlling the vertical drive component 609 to drive the second wire wheel 603 to move closer to or away from the first wire wheel 602, the data of the pressure sensor on the vertical drive component 609 is changed, thereby adjusting the fineness of the drawn metal wire 700.
