Description

Technical Field

[0001] The present invention relates to the technical field of metal wire transportation, and more specifically, it relates to a transportation device and a transportation method for alloy wire processing. Background Art

[0002] During the transportation of metal wires, the pulling force of the driving wheel often causes the wire to bear a large tension, which easily leads to the wire being broken during transportation. Once the wire breaks, if not dealt with in time, it will not only interrupt the transportation process, but may also cause the equipment to stop and affect the subsequent production progress. In addition, resuming transportation requires a large amount of time and extra labor because the broken wires must be reconnected, or the equipment state must be adjusted to adapt to the new wire length, which seriously affects production efficiency and cost control.

[0003] In the prior art, although there are some methods to reduce the risk of metal wire breakage, most of these methods are limited to improving the materials and processes of the metal wire itself, or making improvements to the transportation equipment, and have not fundamentally solved the breakage problem caused by excessive tension.

[0004] In the case of high-speed transportation, the sudden breakage of the wire will cause more serious production interruptions and increase the rejection rate. There is currently a lack of effective solutions for real-time monitoring and effective control of the tension during transportation, resulting in the problem of metal wire breakage during transportation still being widespread. In response to this problem, there is an urgent need to develop a new technical solution to ensure that the metal wire can be quickly restored after being broken, thereby improving production efficiency and reducing resource waste. Summary of the Invention

[0015] The present invention also provides a conveying method for a conveying device for alloy wire processing. According to an embodiment of the present invention, it includes the following steps: S1, threading the alloy wire into the device from the wire wheel of the wire guiding module, and the wire is wound around the wire wheel, auxiliary wheel, guiding wheel a, tensioning wheel, guiding wheel b, and driving wheel in sequence; S2, driving the threading module to move it between the auxiliary wheel and the guiding wheel a through the Y-axis truss, X-axis truss, and Z-axis truss on the three-axis walking bracket, and clamping the wire by the first one-way wheel and the second one-way wheel on the threading module; S3, driving the guiding wheels on both sides of the tensioning wheel to press the wire from above, and at the same time driving the tensioning wheel to press the wire from below to ensure that the wire maintains an appropriate tension; starting the driving module to drive the first sprocket to drive the driving wheel to rotate so as to convey the wire; S3.1, adjusting the spring force of the first spring through the nut block to set the preset value of the damping force of the clutch module, and this preset value is the minimum pulling force value obtained by testing. After adjusting the preset value: if the driving wheel pulls the wire too tightly, but the wire tension does not exceed the rated pulling force value, that is, the wire is not broken at this time, then execute S3.2; if the clutch module fails and the wire tension exceeds the rated pulling force value, and the wire is broken at this time, then execute S3.3; S3.2, the clutch module slips, that is, slipping occurs between the first felt and the second felt on the third support shaft, resulting in the power transmission from the first sprocket to the driving wheel being cut off, and the wire conveying is paused to avoid breaking the wire. When the wire tension is less than the preset value, the first felt and the second felt on the third support shaft are re-engaged, and the wire conveying is resumed; S3.3, since the first one-way wheel and the second one-way wheel on the threading module always clamp the wire, and at the same time the first one-way wheel and the second one-way wheel are one-way wheels, the wire is prevented from retracting at the threading module under the clamping of the first one-way wheel and the second one-way wheel; S3.3.1, then, start the first telescopic devices on both sides of the second telescopic device, drive the guiding wheels a and b on both sides of the tensioning wheel to rise above the wire wheel through the first telescopic devices. At the same time, start the second telescopic device to lower the tensioning wheel below the wire wheel, and then drive the X-axis slider on the three-axis walking bracket to move horizontally, so as to pull the wire to the lower part of the driving wheel through the threading module. At this time, drive the Z-axis truss on the three-axis walking bracket to move vertically, adjust the height of the threading module above the driving wheel, and move it to one side to wind the wire around the driving wheel; S3.3.2, start the first telescopic devices on both sides again to drive the guiding wheels a and b to rise, and at the same time start the second telescopic device to lower the tensioning wheel; make the guiding wheels a and b press the wire from above respectively, and the tensioning wheel presses the wire from below, complete the reset of the wire conveying, and convey the wire again; S4, complete the wire conveying.

[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. In this solution, by connecting the clutch module to the drive module, continuous or intermittent wire feeding is achieved, ensuring the stability and continuity of wire output, avoiding wire breakage, effectively realizing stable wire feeding and tensioning, and ensuring quality stability and efficiency improvement during the wire feeding process.

[0017] 2. In this solution, by adding a wire threading module to the wire transportation path, the broken wire is re-guided and resumed feeding by the wire threading module. In this way, the wire is re-guided back to the normal path of the conveyor belt by the wire threading module, thus avoiding production interruption caused by wire breakage, ensuring continuous wire feeding, improving production efficiency and product quality, and further avoiding the risks brought by manual wire threading.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 shown, it is a conveying device for alloy wire processing according to the first embodiment of the present invention. A machine platform 1 is provided on the conveying device. A wire guiding module 5 and a fixed bracket 7 are sequentially provided on the machine platform 1. The wire guiding module 5 includes a support frame 501 and a wire guiding wheel 502 for guiding the silk thread 13. Specifically, the support frame 501 is fixedly connected to the upper end surface of the machine platform 1 and the top end of the support frame 501 is horizontal. In this embodiment, three wire guiding wheels 502 are provided. As Figure 1As shown, the rotation axis of the wire pulley 502 is perpendicular to the support frame 501, and the three wire pulleys 502 are all arranged in the same rotation plane. The wire pulleys 502 are staggeredly installed on the support frame 501. A wire groove is provided on the wheel surface of the wire pulley 502. The silk thread 13 passes through the wire groove between the wire pulleys 502, and the wire groove provides a guiding function for the silk thread 13 to prevent the silk thread 13 from slipping up and down, affecting the conveying quality of the silk thread 13.

[0022] Next, a tensioning module 4 is provided on the fixed bracket 7, and adjusting modules 3 are provided on both sides of the tensioning module 4. As can be seen from Figure 4 it, the tensioning module 4 includes a tensioning wheel 401, and the adjusting module 3 includes guide wheels 301 located on both sides of the tensioning wheel 401. A driving wheel 10 is provided at the end of the fixed bracket 7. The silk thread 13 passes through the wire pulley 502 and is successively wound around the guide wheel 301 and the tensioning wheel 401 and then reaches the driving wheel 10. The driving wheel 10 is rotatably installed on the fixed bracket 7 through a third support shaft 901. The other end of the third support shaft 901 is power-connected to the driving module through a clutch module. Among them, the tensioning module 4 on the fixed bracket 7 ensures that the silk thread 13 maintains an appropriate tension when passing through this area through the tensioning wheel 401, preventing it from slipping or loosening. The adjusting modules 3 on both sides of the tensioning module 4 guide the path of the silk thread 13 through the guide wheels 301 to ensure that the silk thread 13 passes through the tensioning wheel 401 smoothly and orderly. The driving wheel 10 at the end of the fixed bracket 7 is installed through the third support shaft 901 and is connected to the driving module and the clutch module, responsible for finally pulling the silk thread 13. The coordinated work of this series of modules enables the silk thread 13 to smoothly pass out of the wire pulley 502, be tensioned by the tensioning wheel 401, and finally be guided to the driving wheel 10, realizing the continuous and stable pulling of the silk thread 13.

[0023] To prevent the wire from breaking when the driving wheel 10 pulls the silk thread 13, a clutch module is provided on the third support shaft 901, as shown in Figure 2 and 3As shown in the figure, the clutch module includes a second rotating support seat 906 fixedly connected to the fixed bracket 7. The third support shaft 901 is rotatably installed on the fixed bracket 7 through the second rotating support seat 906. One end of the third support shaft 901 away from the driving wheel 10 is installed with a first sprocket 9 through a bearing. After the third support shaft 901 extends out of the first sprocket 9, a first felt 902 and a second felt 903 are successively arranged. The first felt 902 is sleeved on the third support shaft 901 and fixedly connected to the side of the first sprocket 9. The second felt 903 is circumferentially fixed and axially slidably connected to the third support shaft 901. In this embodiment, a spline fit can be adopted between the second felt 903 and the third support shaft 901, which will not be elaborated here. The end of the third support shaft 901 is provided with a thread and is connected with a nut block 905 through the thread. A first spring 904 is sleeved on the third support shaft 901 between the nut block 905 and the second felt 903. The first spring 904 presses the second felt 903 against the first felt 902 under the reaction force of the nut block 905. The driving module includes a driving motor 11. One end of the driving motor 11 is connected with a second sprocket 12. The first sprocket 9 and the second sprocket 12 are connected by a chain drive; wherein, the tensioning wheel 401 in the tensioning module 4 is used to ensure that the wire 13 can be stably kept in a tensioned state and prevent it from loosening during the threading process; the adjusting modules 3 on both sides of the fixed bracket 7 assist in adjusting the path of the wire 13 through the guide wheels 301 to ensure its correct winding and transmission; the driving wheel 10 is fixed at the end of the bracket, responsible for the final guiding, and generates tension through the winding process; the third support shaft 901 and the clutch module transfer the power from the driving module to the driving wheel 10 to make it rotate.

[0024] It can be seen that when the driving module is started, the power is transmitted to the driving wheel 10 through the clutch module. The driving wheel 10 then rotates through the third support shaft 901, pulling the wire 13 through the guide wheel 502, the guide wheel 301 and the tensioning wheel 401 in sequence, and finally reaching the driving wheel 10 to complete the winding and tensioning process. During this period, when the tension reaches the preset value, the clutch module cuts off the connection between the driving wheel 10 and the power source, so as to maintain a safe tension of the wire 13. When the tension returns to normal, the clutch module reconnects and continues to convey the wire 13. Through flexible and delicate control, the over-tight tension can be processed in time during the conveying process to prevent the wire 13 from breaking.

[0025] Such as Figure 4As shown in the figure, the tensioning module 4 includes a second adjusting frame 402. Inside the second adjusting frame 402, a second sliding seat 404 and an adjusting seat 406 are slidably arranged one above the other. Second sliding blocks 4021 are provided on the inner walls of both sides of the second adjusting frame 402. Sliding grooves adapted to the second sliding blocks 4021 are formed on both sides of the second sliding seat 404 and the adjusting seat 406. A second telescopic device 403 is provided above the second adjusting frame 402. The output rod of the second telescopic device 403 is arranged downward. A passing hole for the output rod of the second telescopic device 403 to pass through is formed on the second sliding seat 404. The output rod of the second telescopic device 403 passes through the passing hole and is fixedly connected to the top end of the adjusting seat 406 downward. A second spring 407 is sleeved on the output rod of the second telescopic device 403 between the second sliding seat 404 and the adjusting seat 406. The tensioning wheel 401 is rotatably installed on the side of the second sliding seat 404 through a second support shaft 405. The design of the second sliding blocks 4021 and the sliding grooves ensures the stable movement of the sliding seat. The second telescopic device 403 is used to drive the second sliding seat 404 and the adjusting seat 406 to move up and down. The second spring 407 is set as a buffer. When the tensioning wheel 401 abuts against the wire 13, a part of the second spring 407 is compressed, which can reduce the impact force during the tensioning process and can also realize the automatic adjustment of the tensioning force, making the tensioning effect more stable.

[0026] Furthermore, the adjusting modules 3 on both sides of the tensioning module 4 have the same structure. The adjusting module 3 includes a first adjusting frame 302 connected to the fixed bracket 7. First sliding blocks 3021 are provided on the inner walls of both sides of the first adjusting frame 302. A first sliding seat 304 is also slidably arranged inside the first adjusting frame 302. Sliding grooves adapted to the first sliding blocks 3021 are formed on both sides of the first sliding seat 304. A first telescopic device 303 is provided above the first adjusting frame 302. The first telescopic device 303 is fixedly connected to the fixed bracket 7. The output rod of the first telescopic device 303 extends downward and is fixedly connected to the top end of the first sliding seat 304. A bearing hole is formed on the first sliding seat 304 and a first support shaft 305 is installed in the bearing hole. The guide wheel 301 is fixedly sleeved on one end of the first support shaft 305. The first sliding seat 304 slides inside the first adjusting frame 302 through the first sliding blocks 3021 and the sliding grooves, enabling the first sliding seat 304 to move along the guide of the first adjusting frame 302. The other end of the first telescopic device 303 is connected to the fixed bracket 7, and the telescopic movement of its output rod enables the first sliding seat 304 to move up and down, thereby adjusting the position of the guide wheel 301. Therefore, by adjusting the height of the guide wheel 301, the wire 13 can be better tensioned in cooperation with the tensioning wheel 401. It can be seen that through the telescopic movements of the first telescopic device 303 and the second telescopic device 403, the sliding seat can be driven to move up and down, thereby adjusting the positions and the tensioning forces of the tensioning wheel 401 and the guide wheel 301, ensuring that the wire 13 has an appropriate tension during the transportation process.

[0027] In addition, in order to improve the stability of the wire 13 during transportation, an auxiliary wheel 8 is further provided between the fixed bracket 7 and the wire guiding wheel 502. The auxiliary wheel 8 is mounted on the fixed bracket 7 through a first rotating support base 801. The top end of the auxiliary wheel 8 is tangent to the wire 13 led out from the wire guiding wheel 502, so that the wire 13 can be better smoothly transitioned from the wire guiding wheel 502, reducing the wear and knotting of the wire 13. And when pulling the wire 13 horizontally to lead it out from the wire guiding wheel 502, it is more smooth, improving the transportation stability of the wire 13.

[0028] It should be noted that in this embodiment, the first sprocket 9 and the second sprocket 12 can be replaced by synchronous belt wheels, and the power connection between the two synchronous belt wheels is realized through a toothed synchronous belt. The synchronous belt wheel has the characteristic of precise transmission. After using the synchronous belt wheel to replace the original sprocket, the power can be transmitted more accurately, reducing the vibration and noise during operation. Compared with the chain belt, the synchronous belt reduces the wear and lubrication requirements, so the maintenance cost is lower. In order to be adapted to the clutch module, the synchronous belt wheel replacing the first sprocket 9 needs to be fixedly connected with the first felt 902 to ensure the normal operation of the clutch module.

[0029] In summary, the first embodiment of the present invention provides a conveying device for alloy wire processing, mainly composed of a wire guiding module 5, a fixed bracket 7 and an adjusting module 3. Among them, the wire guiding module 5 is provided with a support frame 501 and a wire guiding wheel 502, which are used to provide guidance for the wire 13 and ensure that the wire 13 passes through smoothly. A tensioning module 4 and an adjusting module 3 are arranged on the fixed bracket 7. The tensioning wheel 401 in the tensioning module 4 ensures that the wire 13 maintains an appropriate tension when passing through, while the adjusting module 3 guides the path of the wire 13 through the guide wheel 301 to ensure its flat transmission. The tensioning module 4 further includes a third support shaft 901 with a clutch module to ensure the safe tension of the wire 13 during tensioning and prevent breakage caused by over-tightening. In order to further improve the tension adjustment accuracy, a second spring 407 is arranged in the tensioning module 4 as a buffer to achieve uniform and stable tension. In addition, the device is also equipped with an auxiliary wheel 8 to reduce the wear and knotting of the wire 13 during the process from the wire guiding wheel 502 to the guide wheel 301, increasing the stability, so as to ensure the continuous, stable and high-quality conveying of the alloy wire 13.

[0030] As Figure 5 shown, the second embodiment of the present invention is different from the first embodiment in that in order to quickly resume production after a wire break, a three-axis walking bracket 2 and a threading module 6 for clamping the wire 13 and laying out the broken wire are provided in the second embodiment. The three-axis walking bracket 2 is equivalent to a three-axis moving platform, which is installed on the machine table 1, and in order to achieve the threading effect of the threading module 6, the three-axis walking bracket 2 also needs to span across the entire fixed bracket 7.

[0031] Specifically, asFigure 5 , 6 As shown in FIGS. 6 and 7, the three-axis walking bracket 2 includes a Y-axis truss 201 and an X-axis truss 202. The lower end faces at both ends of the X-axis truss 202 are slidably connected to the upper end face of the Y-axis truss 201. An X-axis slider 206 is slidably mounted on the side of the X-axis truss 202. A Z-axis truss 203 is also slidably connected to the X-axis slider 206. The wire threading module 6 is installed at the bottom end of the Z-axis truss 203. A Y-axis rack 204 is provided on the upper end face of one side of the Y-axis truss 201. A first reduction gear 208 is fixedly installed on the X-axis truss 202. A driving gear meshing with the Y-axis rack 204 is further installed on the output end of the first reduction gear 208; an X-axis rack 205 is installed on the corresponding side surfaces of the X-axis truss 202 and the X-axis slider 206.

[0033] As Figure 9As shown, two one-way wheels can clamp the silk thread 13. When the silk thread 13 passes through the first and second one-way wheels 608, it can only run along the conveying direction of the device. That is, during the conveying process of the silk thread 13, the silk threads 13 on both sides of the driving wheel 10 are in two states of tension and compression. Through analysis, it can be known that the silk thread 13 between the auxiliary wheel 8 and the first sprocket 9 is always in a state of tension or tautness, that is, any part of this silk thread 13 is extremely prone to breakage. Since the silk thread 13 can smoothly enter the auxiliary wheel 8, based on this, the initial position of the threading module 6 in this embodiment can be set on one side of the auxiliary wheel 8. And considering the situation that the threading module 6 needs to re-thread the silk thread after breakage, the threading module 6 needs to be set on the side of the auxiliary wheel 8 away from the wire guiding module 5, which can be referred to Figure 10 As shown; when the silk thread 13 is broken, the first one-way wheel 605 and the second one-way wheel 608 on the threading module 6 have a backstop effect on the silk thread 13. Then, through the Y-axis truss 201, X-axis truss 202, and Z-axis truss 203 on the three-axis walking bracket 2, the whole threading module 6 is driven to displace, realizing the re-threading of the silk thread 13 after breakage, thus avoiding the problems of long-time shutdown affecting work efficiency and the risk of manual threading.

[0034] As Figure 10 and 11 As shown in S1, Thread the alloy silk thread 13 into the device from the wire guiding wheel 502 of the wire guiding module 5. The guiding wheel a 3011 and the guiding wheel b 3012 are respectively located on both sides of the tensioning wheel 401. The silk thread 13 is wound around the wire guiding wheel 502, auxiliary wheel 8, guiding wheel a 3011, tensioning wheel 401, guiding wheel b 3012, and driving wheel 10 in sequence.

[0035] S2, Drive the threading module 6 through the Y-axis truss 201, X-axis truss 202, and Z-axis truss 203 on the three-axis walking bracket 2 to move it between the auxiliary wheel 8 and the guiding wheel a 3011, and clamp the silk thread 13 with the first one-way wheel 605 and the second one-way wheel 608 on the threading module 6.

[0036] S3, Drive the guiding wheels 301 on both sides of the tensioning wheel 401 to press the silk thread 13 from above, and at the same time drive the tensioning wheel 401 to press the silk thread 13 from below to ensure that the silk thread 13 maintains an appropriate tension; start the driving module to drive the first sprocket 9 to drive the driving wheel 10 to rotate to convey the silk thread 13.

[0037] S3.1, adjust the spring force of the first spring 904 through the nut block 905 to set the preset value of the damping force of the clutch module. This preset value is the minimum pulling force value obtained by testing to break the wire 13. After adjusting the preset value: If the driving wheel 10 pulls the wire 13 too tightly, but the tension of the wire 13 does not exceed the rated pulling force value, that is, the wire 13 is not broken at this time, then execute S3.2; If the clutch module fails and the tension of the wire 13 exceeds the rated pulling force value, and the wire 13 is broken at this time, then execute S3.3.

[0038] S3.2, the clutch module slips, that is, slipping occurs between the first felt 902 and the second felt 903 on the third support shaft 901, resulting in the power transmission between the first sprocket 9 and the driving wheel 10 being cut off, and the feeding of the wire 13 is paused to avoid breaking the wire 13. When the tension of the wire 13 is less than the preset value, the first felt 902 and the second felt 903 on the third support shaft 901 are re-engaged, and the feeding of the wire 13 is resumed.

[0039] S3.3, refer to Figure 10 As shown, since the first one-way wheel 605 and the second one-way wheel 608 on the wire threading module 6 always clamp the wire 13, and at the same time the first one-way wheel 605 and the second one-way wheel 608 are one-way wheels, the wire 13 is prevented from retracting at the wire threading module 6 under the clamping of the first one-way wheel 605 and the second one-way wheel 608.

[0040] S3.3.1, then, refer to Figure 11 As shown, start the first telescopic devices 303 on both sides of the second telescopic device 403, drive the guide wheel a 3011 and the guide wheel b 3012 on both sides of the tension wheel 401 to rise above the wire guide wheel 502 through the first telescopic devices 303. At the same time, start the second telescopic device 403 to lower the tension wheel 401 below the wire guide wheel 502, and then drive the X-axis slider 206 on the three-axis walking bracket 2 to move horizontally, so as to pull the wire 13 to the lower part of the driving wheel 10 through the wire threading module 6. At this time, drive the Z-axis truss 203 on the three-axis walking bracket 2 to move vertically, adjust the height of the wire threading module 6 above the driving wheel 10, and move to one side to wind the wire 13 around the driving wheel 10.

[0041] S3.3.2, start the first telescopic devices 303 on both sides again to drive the guide wheel a 3011 and the guide wheel b 3012 to rise, and at the same time start the second telescopic device 403 to lower the tension wheel 401; so that the guide wheel a 3011 and the guide wheel b 3012 press the wire 13 from above respectively, and the tension wheel 401 presses the wire 13 from below, complete the reset of the wire 13 feeding, and resume the feeding of the wire 13.

[0042] S4, complete the feeding of the wire 13.

[0043] In summary, the wire module 5 feeds the alloy wire 13 into the device and moves and positions itself through the Y-axis truss 201, X-axis truss 202, and Z-axis truss 203 to accurately guide the wire 13 to the required area; the Y-axis truss 201, X-axis truss 202, and Z-axis truss 203 on the three-axis walking bracket 2 are used to finely adjust the position of the wire threading module 6 so that it can accurately reach the key points on the transfer path of the alloy wire 13; the first one-way wheel 605 and the second one-way wheel 608 clamp the wire 13 during the main transmission process to prevent it from retracting; the tensioning wheel 401 presses the wire 13 up and down to ensure that it maintains an appropriate tension; there is a certain damping force between the first felt 902 and the second felt 903 in the clutch module to prevent the wire 13 from being broken due to excessive tension; the first spring 904 can adjust the preset value of this damping force to ensure that the wire 13 is not broken during the tensioning process; the nut block 905 is used to adjust the tensioning degree of the first spring 904, thereby ensuring an appropriate damping force for the clutch module; the telescopic device is responsible for resetting the wire threading module 6 by lifting the guide wheel 301 and lowering the tensioning wheel 401 when the wire 13 breaks, so as to convey the wire 13 again.

[0044] Its working principle is as follows: After the alloy wire 13 is threaded, the three-axis walking bracket 2 and its trusses drive the wire threading module 6 to accurately move to the key positions where the alloy wire 13 passes through. The first one-way wheel 605 and the second one-way wheel 608 clamp the wire 13, and the tension is adjusted in cooperation with the tensioning wheel 401 to maintain the stable transmission of the alloy wire 13; through the damping force adjustment of the clutch module, it is ensured that the tensioning of the wire 13 will not cause breakage; in the case of a sudden over-tight pulling force, the structural design of the clutch module causes the first felt 902 and the second felt 903 to slip, thereby cutting off the power transmission and protecting the wire 13 from excessive damage; if the wire 13 finally breaks, the system resets through the action of the telescopic device, readjusts the positions of the clamping mechanism and the tensioning wheel 401, and cooperates with the wire threading module 6 to start the conveying process again to ensure the efficient operation of the entire wire transmission system.
