[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but cannot be understood as limiting the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0032] like Figure 1 As shown, the steel wire unwinding device 1 according to the embodiment of the present invention includes a wire rack 11, on which the steel wire roll is suitable for being placed, and the wire rack 11 is suitable for releasing the steel wire 10. In other words, the steel wire 10 is suitable for being released from the steel wire outlet of the wire rack 11, that is, the steel wire roll is unwound. The unwound steel wire 10 is supplied to the spring coiling machine for the next process; in the actual production process, the demand for steel wire 10 of the spring coiling machine is not uniform, so the supply speed of the steel wire roll will change, and when the supply speed of the steel wire 10 changes, the tension of the steel wire will also change. For example, when the supply speed slows down, the tension of the steel wire 10 will decrease, causing the steel wire 10 to relax, and the relaxed steel wire 10 may cause the steel wire 10 to be kinked or twisted, and the workers need to sort out the steel wire 10 before working, which seriously affects the production efficiency.

[0033] For this reason, Figure 1 and Figure 2 As shown, the steel wire unwinding device 1 according to the present invention further comprises an anti-kink component 13, the anti-kink component 13 is arranged along the conveying direction ( Figure 1 The spring coiling machine 13 includes a spring guide plate 131 and a spring guide plate 132. The spring guide plate 131 ...

[0034] According to the steel wire unwinding device 1 of the present invention, an anti-kink component 13 is arranged downstream of the steel wire outlet of the wire rack 11, and the steel wire 10 passes through the wire guide hole 1311 of the wire guide plate 131 in the anti-kink component 13. The movable wire guide plate 131 can tighten the steel wire 10 that is relaxed due to the reduction of tension to maintain the tension of the steel wire 10. That is, the anti-kink component 13 can store the steel wire that is released from the wire rack 11 due to inertia or released during the debugging process, so as to avoid the steel wire 10 from being tangled and twisted due to being too relaxed, thereby improving the reliability of the steel wire unwinding device 1 and ensuring production efficiency.

[0035] According to one embodiment of the present invention, the steel wire unwinding device further comprises an adjusting component 12, which is arranged at the steel wire outlet of the wire rack 11 and is located upstream of the anti-kink component 13 along the conveying direction of the steel wire, so as to adjust the supply speed of the steel wire 10 released from the wire rack 11. Figure 1As shown, the wire rack 11 is provided with a turntable 111 suitable for driving the wire coil to rotate. The wire coil is unwound as the turntable 111 rotates. The unwound wire 10 can pass through the wire outlet of the wire rack 11 and enter the adjustment component 12. The adjustment component 12 adjusts the supply speed of the unwound wire 10. After passing through the adjustment component 12, the wire 10 enters the anti-kink component 13.

[0036] It is understandable that the wire rack 11 in the above manner is an active unwinding wire rack. It is understandable that the present application is not limited thereto, for example, the wire rack 11 can also be a passive unwinding wire rack, and there is no adjustment component at the wire outlet of the wire rack. In other words, the steel wire released by active unwinding and the steel wire released by passive unwinding can both be prevented from twisting or kinking by the anti-kink component 13.

[0037] According to one embodiment of the present invention, the wire guide plate 131 is movable up and down in the vertical direction. After the steel wire 10 passes through the wire guide hole 1311 on the wire guide plate 131, the steel wire 10 moves in the vertical direction to tension the steel wire 10, which can prevent the steel wire 10 from twisting or kinking to a certain extent.

[0038] According to one embodiment of the present invention, the anti-kink assembly 13 also includes a bracket 132 and a sliding rod 133, the first end of the sliding rod 133 and the second end of the sliding rod 133 are both connected to the bracket 132, and the wire guide plate 131 is arranged on the sliding rod 133 and is movable along the axial direction of the sliding rod 133.

[0039] like Figure 1 As shown, the bracket 132 can be fixed on the ground at the production site to ensure the reliability of the anti-kink assembly 13; the sliding rod 133 can be fixed to the bracket 132, and the wire guide plate 131 moves in the axial direction of the sliding rod 133. The sliding rod 133 is suitable for limiting the moving direction of the wire guide plate 131. Since the steel wire passes through the wire guide hole 1311 on the wire guide plate 131, the wire guide plate 131 moves to drive the steel wire to move to tension the steel wire 10. Therefore, the anti-kink assembly 13 can tension the steel wire 10 to prevent the steel wire 10 from twisting or kinking.

[0040] In one embodiment of the present invention, Figure 2 As shown, the anti-kink component 13 also includes a slider 134, which is sleeved on the slide rod 133 and movable along the axial direction of the slide rod 133. The wire guide plate 131 is arranged on the slider 134 and can be fixedly connected with the slider 134. The slider 134 is provided with a through hole that cooperates with the slide rod 133. The slide rod 133 passes through the through hole on the slider 134 to realize the axial movement of the slider 134 on the slide rod 133, thereby driving the wire guide plate 131 to move through the slider 134.

[0041] exist Figure 2In one example shown, the slider 134 drives the wire guide plate 131 to move in the vertical direction, and the gravity of the slider 134 is applied to the steel wire 10 through the wire guide hole 1311 on the wire guide plate 131 to increase the pressing force on the steel wire 10, further ensure the tension of the steel wire 10 to prevent the steel wire from loosening, and improve the reliability of the anti-kink assembly 13. Since the tension of the steel wire 10 in the relaxed state is less than the sum of the gravity of the slider 134 and the gravity of the wire guide plate 131, the steel wire 10 inserted in the wire guide hole 1311 moves downward under the gravity of the slider 134 and the gravity of the wire guide plate 131 to tension the steel wire 10. When the tension of the steel wire 10 is large, the tension of the steel wire 10 is greater than the sum of the gravity of the slider 134 and the gravity of the wire guide plate 131, so as to drive the wire guide plate 131 and the slider 134 to move upward.

[0042] According to an embodiment of the present invention, the bracket 132 includes a first support plate 1321 and a second support plate 1322 spaced apart from each other, a first end of the slide bar 133 is connected to the first support plate 1321, and a second end of the slide bar 133 is connected to the second support plate 1322. The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0043] like Figure 1 As shown, in a specific embodiment of the present invention, the slide bar 133 extends in the vertical direction, the second support plate 1322 is located below the first support plate 1321, and the first support plate 1321 and the second support plate 1322 are opposite to each other in the vertical direction, and the slide bar 133 is arranged between the first support plate 1321 and the second support plate 1322. The second support plate 1322 can be fixed on the ground, and the second support plate 1322 can be provided with a mounting hole, and the fastener can pass through the mounting hole to fix the second support plate 1322 on the ground; a connecting plate 1323 can be arranged between the first support plate 1321 and the second support plate 1322.

[0044] Among them, the first end of the sliding rod 133 is the upper end and is fixed on the first support plate 1321, and the second end of the sliding rod 133 is the lower end fixed on the second support plate 1322. The setting of the second support plate 1322 can ensure the reliability of the bracket 132 and increase the contact area between the bracket 132 and the ground. The setting of the first support plate 1321 is suitable for fixing the first end of the sliding rod 133, so that both ends of the sliding rod 133 are fixed to the bracket 132, thereby ensuring the reliability of the connection between the sliding rod 133 and the bracket 132.

[0045] According to one embodiment of the present invention, the anti-kink assembly 13 further includes an elastic member 135, the elastic member 135 having a first end and a second end, the first end of the elastic member 135 is connected to the bracket 132, and the second end of the elastic member 135 is directly or indirectly connected to the wire guide plate 131. Specifically, Figure 1As shown, the first end of the elastic member 135 can be the upper end, the first end of the elastic member 135 can be fixed on the first support plate 1321, and the second end of the elastic member 135 can be connected to the slider 134 to be indirectly connected to the wire guide plate 131. Of course, the second end of the elastic member 135 can also be directly connected to the wire guide plate 131.

[0046] When the conveying speed of the steel wire changes from slow to fast, the surface tension of the steel wire increases instantly. At this time, the surface tension of the steel wire 10 may be greater than the sum of the gravity of the wire guide plate 131 and the slider 134. The surface tension of the steel wire 10 will push the wire guide plate 131 and the slider 134 to move upward. When the surface tension of the steel wire 10 is large, the moving speed of the slider 134 and the wire guide plate 131 is very fast. The slider 134 and the wire guide plate 131 quickly move toward the first end of the slide bar 133. The slider 134 and the wire guide plate 131 may collide with the first support plate 1321. Therefore, when the wire guide plate 131 An elastic member 135 is arranged between the first support plate 1321. On the one hand, the elastic member 135 can buffer the slider 134 and the wire guide plate 131 to prevent the slider 134 and the wire guide plate 131 from directly hitting the bracket 132; on the other hand, when the supply speed of the steel wire 10 is slow, the tension of the steel wire 10 is small, and the elastic member 135 can be in a compressed state. The elastic force of the elastic member 135 can be transmitted to the steel wire 10 through the slider 134 and the wire guide plate 131 to further press the steel wire 10, increase the tension of the steel wire 10, and prevent the steel wire 10 from twisting or kinking.

[0047] According to one embodiment of the present invention, the elastic member 135 can be constructed as a spring, which can be mounted on the slide rod 133, the upper end of the spring is fixed to the first support plate 1321, and the lower end of the spring can be pressed against the slider 134, and indirectly connected to the guide wire plate 131 through the slider 134.

[0048] According to one embodiment of the present invention, the anti-kink assembly 13 further includes a buffer 136 , which is adjacent to the second end of the sliding rod 133 and opposite to the wire guide plate 131 for buffering the wire guide plate 131 .

[0049] Among them, Figure 1As shown, the buffer 136 is arranged at the lower end of the slide bar 133. When the supply speed of the steel wire 10 is slow until it stops, the tension of the steel wire 10 decreases, and the wire guide plate 131 drives the steel wire 10 to move downward to tension the steel wire 10. In order to prevent the collision between the wire guide plate 131 and / or the slider 134 and the second support plate 1322, the buffer 136 is arranged at the upper end of the second support plate 1322 and directly opposite to the wire guide plate 131. When the wire guide plate 131 moves downward, the buffer 136 is suitable for buffering the impact force of the wire guide plate 131 to prevent the wire guide plate 131 and the slider 134 from directly colliding with the second support plate 1322. Specifically, the buffer 136 is a spring, which is sleeved at the lower end of the slide bar 133.

[0050] According to one embodiment of the present invention, the adjustment assembly 12 includes a support frame 121, a guide wheel, a guide rod 123, a tensioning adjustment wheel 124 and a first sensor 101, the support frame 121 is connected to the wire rack 11, the guide wheel is arranged on the support frame 121, the guide rod 123 is arranged on the support frame 121, and the tensioning adjustment wheel 124 is arranged on the guide rod 123 and is movable along the axial direction of the guide rod 123.

[0051] The steel wire 10 enters the adjustment assembly 12 from the steel wire outlet of the wire rack 11, and the steel wire 10 can be wrapped around the outer peripheral wall of the guide wheel and the outer peripheral wall of the tensioning adjustment wheel 124. It should be noted that the steel wire 10 does not wrap around the guide wheel and then around the tensioning adjustment wheel 124, but the guide wheel and the tensioning adjustment wheel 124 are both arranged on the inner periphery of the circle formed by the steel wire 10, and the guide wheel and the tensioning adjustment wheel 124 are suitable for maintaining the size of the circle formed by the steel wire 10. The tensioning adjustment wheel 124 is arranged on the guide rod 123 and moves along the axial direction of the guide rod 123. The size of the circle formed by the steel wire 10 is adjusted by changing the position of the tensioning adjustment wheel 124 on the guide rod 123. When the steel wire 10 is relatively loose, the tensioning adjustment wheel 124 moves to tighten the circle formed by the steel wire 10.

[0052] According to one embodiment of the present invention, the steel wire 10 released by the wire rack 11 bypasses the guide wheel and the tensioning adjustment wheel 124 and enters the wire guide hole 1311 from the guide wheel. Since the tensioning adjustment wheel 124 will move, if the steel wire bypasses the tensioning adjustment wheel 124 and then enters the wire guide hole 1311, the movement of the tensioning adjustment wheel 124 will cause the height of the steel wire 10 and the position of the wire guide hole 1311 to change, which will affect the anti-kink component 13. The elastic member 135 in the anti-kink component 13 cannot ensure the stability of the clamping force on the steel wire 10; after bypassing the guide wheel, the steel wire 10 enters the wire guide hole 1311. Since the height of the guide wheel does not change, the height of the steel wire 10 when it is output from the adjustment component 12 can be made consistent, ensuring that the downstream anti-kink component 13 can adjust the tension of the steel wire 10 more reliably.

[0053] The steel wire 10 emitted from the wire rack 11 is wound around the guide wheel and the tension adjustment wheel 124. The first sensor 101 is used to detect the position of the tension adjustment wheel 124 to control the supply speed of the steel wire 10. In actual production, the demand for the steel wire 10 is uneven, that is, the supply speed of the steel wire is different from the demand speed of the steel wire 10, which causes the tension of the steel wire 10 to change accordingly. As the tension of the steel wire 10 changes, the tension adjustment wheel 124 can be moved in the up and down directions. When the demand for the steel wire 10 increases, the steel wire 10 is adjusted to the desired position. The supply speed of the wire 10 remains unchanged, and the downstream end of the wire 10 will tighten the wire 10, so that the tension of the wire 10 is large, and the diameter of the circle formed by the wire 10 wound around the guide wheel and the tensioning adjustment wheel 124 will decrease, and the wire 10 drives the tensioning adjustment wheel 124 to move upward. On the contrary, when the demand speed of the wire 10 becomes smaller, the downstream of the wire 10 will no longer tighten the wire 10, and the tension of the wire 10 is small. The diameter of the circle formed by the wire 10 wound around the guide wheel and the tensioning adjustment wheel 124 will increase, and the tensioning adjustment wheel 124 falls.

[0054] In one embodiment of the present invention, the first sensor 101 is adapted to detect the position of the tension adjustment wheel 124 to control the feeding speed of the steel wire 10. The first sensor 101 is configured to detect the tension adjustment wheel 124 when the tension adjustment wheel 124 is between the upper limit position and the lower limit position. When the required speed of the steel wire 10 increases, the steel wire is tightened, and the tension of the steel wire 10 increases, thereby driving the tension adjusting wheel 124 to move upward, until the tension adjusting wheel 124 exceeds the upper limit position, the first sensor 101 will control the turntable 111 and increase the speed of the turntable 111, thereby accelerating the transmission of the steel wire 10, that is, high-speed supply to meet the multiple needs of the downstream machine, reduce the tension of the steel wire 10, and make the tension adjusting wheel 124 fall and return to between the upper limit position and the lower limit position; when the required speed of the steel wire decreases, the steel wire relaxes to reduce its tension, and the tension adjusting wheel 124 moves downward, until the tension adjusting wheel 124 exceeds the lower limit position, the first sensor 101 will control the turntable 111 and reduce the speed of the turntable 111, thereby slowing down the transmission of the steel wire 10, that is, low-speed supply to meet the small needs of the downstream machine, increase the tension of the steel wire 10, and make the tension adjusting wheel 124 rise and return to between the upper limit position and the lower limit position.

[0055] According to an embodiment of the present invention, the first sensor 101 is adapted to control the feeding speed of the steel wire 10 to increase when the tension adjustment wheel 124 is not detected.

[0056] When the tensioning adjustment wheel 124 is detected by the first sensor 101, the tension of the steel wire 10 is appropriate, the required speed of the steel wire 10 is approximately the same as the supply speed of the steel wire 10, and the turntable 111 of the wire rack 11 is at a normal speed. If the tensioning adjustment wheel 124 does not leave the detection range of the first sensor 101 within a period of time (for example, within 10 seconds), the speed of the turntable 111 will decrease to reduce the supply speed of the steel wire 10. Once the first sensor 101 cannot detect the tensioning adjustment wheel 124, that is, the supply speed of the steel wire 10 is less than the required speed of the steel wire 10, the downstream end of the steel wire 10 will tighten the steel wire 10, the tension of the steel wire 10 increases, and the tensioning adjustment wheel 124 moves up so that the first sensor 101 cannot detect the tensioning adjustment wheel 124. The turntable 111 immediately enters a high-speed operation state to increase the supply speed of the steel wire 10 so that the supply speed of the steel wire 10 can match the required speed of the steel wire 10.

[0057] According to one embodiment of the present invention, the adjustment assembly further includes a second sensor 102 , which is located above the first sensor 101 and adjacent to the guide wheel. The second sensor 102 is used to issue a wire pay-off failure alarm when the tension adjustment wheel 124 is detected.

[0058] When the adjustment component 12 fails, the delivery of the steel wire is interrupted, but the downstream demand end of the steel wire continues to demand the steel wire. The steel wire 10 is tightened by the downstream end, and the tension of the steel wire 10 will increase, causing the tensioning adjustment wheel 124 to move upward continuously until the tensioning adjustment wheel 124 is detected by the second sensor 102. At this time, an alarm signal will be issued to remind the staff to prevent accidents.

[0059] According to one embodiment of the present invention, the steel wire 10 wound around the guide wheel and the tensioning adjustment wheel 124 is at least 2 turns. The multiple turns of steel wire 10 are provided to store part of the steel wire 10, leaving time for the tensioning adjustment wheel 124 to slide up and down, thereby leaving time for the turntable 111 to pay out the wire at high speed.

[0060] According to one embodiment of the present invention, the guide wheel includes a first guide wheel 1221, a second guide wheel 1222 and a third guide wheel 1223, and the first guide wheel 1221, the second guide wheel 1222 and the third guide wheel 1223 are arranged in an arc shape, wherein the second guide wheel 1222 is located at the top of the arc, and the tensioning adjustment wheel 124 is opposite to the second guide wheel 1222. The first guide wheel 1221, the second guide wheel 1222 and the third guide wheel 1223 are all arranged on the inner circumference of the circle formed by the steel wire 10, and the first guide wheel 1221, the second guide wheel 1222 and the third guide wheel 1223 are suitable for supporting the upper arc part of the circle surrounded by the steel wire 10, and the second guide wheel 1222 is arranged at the top of the arc.

[0061] According to one embodiment of the present invention, the tensioning adjustment wheel 124 can be arranged directly below the second guide wheel 1222, the guide rod 123 can extend in the vertical direction, and the tensioning adjustment wheel 124 can move in the vertical direction. By changing the position of the tensioning adjustment wheel 124 in the vertical direction, the size of the circle formed by the steel wire 10 can be adjusted, thereby adjusting the tension of the steel wire 10. The tensioning adjustment wheel 124 can tension the steel wire 10 by its own gravity to prevent the steel wire 10 from being loosened, thereby improving the reliability of the steel wire unwinding device 1 and effectively preventing the steel wire 10 from being twisted or kinked.

[0062] Furthermore, the adjustment assembly 12 further includes a slider (not shown) sleeved on the guide rod 123, the slider is movable along the axial direction of the guide rod 123, and a tension adjustment wheel 124 is disposed on the slider. When the steel wire 10 is in a relaxed state, the tension of the steel wire 10 is less than the gravity of the tension adjustment wheel 124 or the sum of the gravity of the slider and the tension adjustment wheel 124, so the tension adjustment wheel 124 moves downward to tighten the circle formed by the steel wire 10.

[0063] According to one embodiment of the present invention, the adjustment assembly 12 further includes a buffer spring 125, which is sleeved on the guide rod 123 and opposite to the tension adjustment wheel 124 to buffer the tension adjustment wheel 124. In order to prevent the tension adjustment wheel 124 from directly impacting the support frame 121, the buffer spring 125 is sleeved on the lower end of the guide rod 123 to buffer the impact force of the tension adjustment wheel 124, thereby improving the reliability of the adjustment assembly 12.

[0064] Please refer to the following Figure 1 and attached Figure 2 A steel wire unwinding device 1 according to a specific embodiment of the present invention is described.

[0065] like Figure 1 and Figure 2 As shown, the steel wire unwinding device 1 according to the embodiment of the present invention comprises: a wire rack 11, an adjusting component 12 and an anti-kink component 13, the wire rack 11 is set as the starting end of the steel wire unwinding device 1, the adjusting component 12 is set downstream of the wire rack 11, and the anti-kink component 13 is set downstream of the adjusting component 12. The steel wire is wound in the wire rack 11 for unwinding, and the unwound steel wire 10 passes through the adjusting component 12 and the anti-kink component 13 in sequence, and the steel wire 10 is transported to the spring winding machine after passing through the anti-kink component 13.

[0066] The wire rack 11 includes a turntable, on which the wire coil is arranged, and the turntable is driven by a variable frequency motor, and the power of the variable frequency motor drives the turntable after the speed is reduced and the torque is increased through the reducer, and the turntable drives the wire coil to rotate so that the wire coil is unwound. A wire outlet is arranged on the upper side of the wire rack 11, and the unwound wire 10 passes through the wire outlet and enters the adjustment component 12.

[0067] The adjustment assembly 12 includes a support frame 121 and a first guide wheel 1221, a second guide wheel 1222 and a third guide wheel 1223 arranged on the support frame 121, and the support frame 121 is connected to the wire rack 11. The support frame 121 includes two upper beams and lower beams that are parallel to each other and spaced apart in the vertical direction, a longitudinal beam connecting the upper beam and the lower beam, and a connecting plate extending in the vertical direction and connected to the lower beam at the lower end, the upper beam is fixedly connected to the wire rack 11, the first guide wheel 1221 and the third guide wheel 1223 are arranged at both ends of the lower beam, and the second guide wheel 1222 is arranged on the connecting plate and is located directly above the midpoint of the line between the first guide wheel 1221 and the third guide wheel 1223.

[0068] The adjustment assembly 12 also includes a guide rod 123 and a tensioning adjustment wheel 124. The guide rod 123 extends in the up-down direction, and the upper end of the guide rod 123 is connected to the lower end of the longitudinal beam. A slider is sleeved on the guide rod 123, and the slider is movable along the axial direction of the guide rod 123, that is, the up-down direction. The tensioning adjustment wheel 124 is arranged on the slider and can move along the vertical direction on the guide rod 123 with the slider. A buffer spring 125 is sleeved on the lower end of the guide rod 123, and the buffer spring 125 is opposite to the tensioning adjustment wheel 124, and is used to buffer the tensioning adjustment wheel 124 to prevent the tensioning adjustment wheel 124 from directly impacting the base.

[0069] Among them, the steel wire 10 is wound around the first guide wheel 1221, the second guide wheel 1222, the third guide wheel 1223 and the tensioning adjustment wheel 124 for at least 2 turns. The multiple turns of steel wire 10 are provided to store part of the steel wire 10, leaving time for the tensioning adjustment wheel 124 to slide up and down, thereby leaving time for the turntable 111 to pay out the wire at high speed.

[0070] The adjustment assembly 12 further includes a first sensor 101 and a second sensor 102. The first sensor 101 is used to detect the position of the tension adjustment wheel 124 to control the feeding speed of the steel wire 10. Specifically, the first sensor 101 is located below the guide wheel and adjacent to the lower end of the guide rod 123. When the tension adjustment wheel 124 is detected by the first sensor 101, the tension of the steel wire 10 is appropriate, the required speed of the steel wire 10 is substantially the same as the feeding speed of the steel wire 10, and the rotating disk 111 of the wire rack 11 is at a normal speed. If the tension adjustment wheel 124 does not leave the detection range of the first sensor 101 within a period of time (for example, within 10 seconds), the rotation speed of the rotating disk 111 will also decrease to reduce the tension of the steel wire 10. The supply speed of the steel wire 10 is adjusted. Once the first sensor 101 cannot detect the tensioning adjusting wheel 124, that is, the supply speed of the steel wire 10 is less than the required speed of the steel wire 10, the downstream end of the steel wire 10 will tighten the steel wire 10, the tension of the steel wire 10 increases, and the tensioning adjusting wheel 124 moves up, so that the first sensor 101 cannot detect the tensioning adjusting wheel 124, and the turntable 111 immediately enters a high-speed operation state to increase the supply speed of the steel wire 10, so that the supply speed of the steel wire 10 can match the required speed of the steel wire 10.

[0071] The second sensor 102 is located above the first sensor 101 and adjacent to the guide wheel. The second sensor 102 is used to issue a wire-release failure alarm when the tension adjustment wheel 124 is detected.

[0072] It can be understood that after unwinding, the steel wire 10 passes through the adjusting assembly 12, and the steel wire 10 successively bypasses the first guide wheel 1221, the second guide wheel 1222, the third guide wheel 1223 and the tensioning adjustment wheel 124, and the inner circumferential wall of the circular ring formed by the steel wire 10 contacts the first guide wheel 1221, the second guide wheel 1222, the third guide wheel 1223 and the tensioning adjustment wheel 124 respectively, and the tensioning adjustment wheel 124 is arranged directly below the inner circumferential wall of the circular ring, and the tensioning adjustment wheel 124 moves downward when the steel wire is relaxed, and moves upward when the steel wire is tightened, and the position of the tensioning adjustment wheel 124 is detected by the first sensor 101 to control the feeding speed of the steel wire 10; when the tensioning adjustment wheel 124 is detected by the second sensor 102, a steel wire 10 unwinding failure alarm is issued to remind the staff to prevent accidents.

[0073] An anti-kink assembly 13 is provided downstream of the adjustment assembly 12, and the anti-kink assembly 13 includes a wire guide plate 131, a bracket 132, and a slide bar 133. The bracket 132 includes a first support plate 1321 and a second support plate 1322 spaced apart in the up-down direction, a connecting plate 1323 is provided between the first support plate 1321 and the second support plate 1322, and the first support plate 1321 and the second support plate 1322 are both fixed to the connecting plate 1323, the first support plate 1321 is provided at the upper end of the connecting plate 1323, the second support plate 1322 is provided at the lower end of the connecting plate 1323, and the first support plate 1321 and the second support plate 1322 are provided at the lower end of the connecting plate 1323. A sliding rod 133 is also provided between 1322, and a slider 134 is sleeved on the sliding rod 133. The slider 134 can slide in the up and down directions of the sliding rod 133. A wire guide plate 131 is provided on the slider 134. A wire guide hole 1311 suitable for the steel wire to pass through is provided on the wire guide plate 131. The steel wire 10 passes through the wire guide hole 1311. The gravity of the slider 134 and the wire guide plate 131 is applied to the steel wire 10 to drive the steel wire 10 to move downward when the steel wire 10 is relaxed to maintain the tension of the steel wire 10.

[0074] An elastic member 135 is also provided between the slider 134 and the first support plate 1321. The elastic member 135 is suitable for buffering the impact force when the wire guide plate 131 and the slider 134 move. In the process of the steel wire 10 going from relaxation to tension, if the tensioning speed of the steel wire is fast, the steel wire 10 drives the wire guide plate 131 and the slider 134 to move quickly. The elastic member 135 is suitable for buffering the impact force generated by the rapid movement of the wire guide plate 131 and the slider 134, so as to prevent the wire guide plate 131 and the slider 134 from directly impacting the first support plate 1321.

[0075] A buffer 136 is provided at the lower end of the slide rod 133. When the steel wire 10 is in a completely relaxed state, it cannot support the wire guide plate 131 and the slider 134. The wire guide plate 131 and the slider 134 move downward. The buffer 136 is suitable for preventing the slider 134 and the wire guide plate 131 from directly hitting the second support plate 1322.

[0076] It is understandable that after the steel wire passes through the adjustment component 12, it enters the anti-kink component 13, and the steel wire 10 passes through the wire guide hole 1311 on the wire guide plate 131. The weight of the slider 134 and the wire guide plate 131 is applied to the steel wire 10 to drive the steel wire 10 to move downward, to tighten the steel wire 10, to prevent the steel wire 10 from loosening, thereby adjusting the tension of the steel wire 10 to prevent the steel wire 10 from twisting or kinking when the supply speed of the steel wire 10 changes. The elastic member 135 provided between the slider 134 and the first support plate 1321 is in a compressed state, so that the elastic force of the spring is pressed on the steel wire through the slider 134 and the wire guide plate 131, and a greater pressure is applied to the steel wire 10 to accelerate the falling of the slider 134 and the wire guide plate 131, and improve the reliability of adjusting the tension of the steel wire 10.

[0077] According to the steel wire unwinding device of the present invention, the steel wire roll can be unwound quickly and reliably. By setting the adjustment component 12 and the anti-kink component 13, the tension of the steel wire 10 can be guaranteed to be reliable. When the supply speed of the steel wire 10 changes, the steel wire 10 can be kept in a tensioned state at all times, which effectively prevents the steel wire 10 from twisting or kinking, thereby improving the reliability of the steel wire unwinding device 1, ensuring the production rhythm, and improving the production efficiency.
