[0002] Wire rod, as a core product of the steel industry, is widely used in downstream sectors such as construction and infrastructure, machinery manufacturing, hardware processing, and automotive parts. When mainstream wire rod production workshops produce wire rods of different diameters and lengths, they can only achieve limited variations in coil shape, length, and diameter through the wire-spinning and oscillating functions in the production line design. This cannot meet the personalized needs of customers, forcing downstream customers to optimize or improve the coil shape and length of the base material produced at the steel mill during production line design and manufacturing. This fails to meet the requirements of downstream customers for personalized, efficient, and low-waste production. How to meet the requirements of downstream customers for personalized, efficient, and low-waste production is a pressing technical problem that needs to be solved in this field.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0019] See Figures 1 to 3 As shown, this invention discloses an embodiment of the wire coil diameter adjustment device and method for a spinning machine.

[0020] The wire coil diameter adjustment device includes a conveyor roller 1 and two limiting units 2. The conveyor roller 1 is used to carry and drive the coil 3 produced by the spinning machine to move. The two limiting units 2 are used to limit the movement trajectory of the coil on the conveyor roller 1 along both sides of the width direction of the conveyor roller 1, so as to limit the size of the coil 3 on the conveyor roller 1 along the width direction of the conveyor roller 1. The position of each limiting unit 2 along the width direction of the conveyor roller 1 is adjustable.

[0021] Specifically, the wire coil diameter adjustment device is used to constrain and adjust the diameter of the coil after the wire is formed. It is applied downstream of the coil forming machine in a high-speed wire production line, achieving stable control of the coil diameter by limiting the lateral displacement of the coil during transport. The conveyor roller 1 carries, supports, and forward-transports the coil 3 produced by the coil forming machine. Two limiting units 2 limit the lateral movement range of the coil 3, thereby controlling the width (coil diameter) of the coil 3. The coil 3 is a ring-shaped wire product formed by the coil forming machine.

[0022] Based on the above-mentioned wire coil diameter adjustment device, a method for adjusting the wire coil diameter of a spinning machine is described below, including the following steps: S1. Set the spinning parameters of the spinning machine and adjust the position of the limiting unit 2 so that the coil diameter of the coil spun out by the spinning machine is not less than the required coil diameter, so that the positions of the two limiting units 2 can restrict the coil 3 on the conveying roller 1 to be located on their respective preset tracks along the width direction of the conveying roller 1. S2. Start the above-mentioned spinning machine. The silk spun out by the spinning machine is sent to the above-mentioned conveyor roller 1. The coil 3 moving on the above-mentioned conveyor roller 1 is deformed to the required coil diameter under the limit of the above-mentioned limiting unit 2.

[0023] Specifically, the coil diameter produced by the coil spinning machine should be greater than or equal to the required coil diameter; otherwise, the coil diameter cannot be adjusted subsequently by the limiting unit 2. During the movement of the coil on the conveyor roller 1, it is gradually limited, guided, and shaped by the limiting units 2 on both sides, and is finally constrained and stabilized at the set coil diameter.

[0024] The above technical solution, through the setting of a limiting unit whose position is adjustable along the width direction, can quickly adapt to the coil diameter requirements of different wire specifications, eliminating the need for downstream customers to adjust the coil. This reduces costs while meeting the needs of downstream customers for high-efficiency, low-cost, and low-waste production, achieving customized needs, improving resource utilization, and reducing carbon emissions.

[0025] In this embodiment, each of the aforementioned limiting units 2 includes a plurality of limiting members 21 arranged sequentially along the length direction of the aforementioned conveying roller 1. The limiting members 21 are used to contact the coil 3 on the aforementioned conveying roller 1.

[0026] Specifically, the limiting component 21 is a single limiting component constituting the limiting unit 2. It is arranged sequentially along the length of the conveying roller 1. As the coil moves with the conveying roller 1, it contacts and limits the coil 3 in segments and gradually, so that the coil 3 is continuously and smoothly constrained and shaped during the movement.

[0027] With the above technical solution, each limiting unit includes multiple limiting components, which sequentially limit the coil at multiple points, resulting in uniform force distribution and a smoother shaping process. The multiple limiting components are independent of each other, making maintenance convenient.

[0028] In this embodiment, the limiting member 21 includes a roller body 211 and a conical head 212 coaxially connected to the roller body 211. The roller body 211 of the limiting member 21 is parallelly embedded between the roller bodies of the conveying roller track 1, and the conical surface of the conical head 212 is used to contact the coil 3 on the conveying roller track 1.

[0029] Specifically, roller body 211 is parallelly embedded between the roller bodies of the conveyor roller table 1 to support and install the conical head 212. The conical head 212 is coaxially connected to the roller body 211 and has a conical surface for contacting the coil 3 and guiding and limiting the coil 3. The roller body 211 of the limiting member 21 is embedded between the roller bodies of the conveyor roller table 1 without interfering with the normal conveying of the conveyor roller table 1; the conical surface of the conical head 212 extends upward / outward, and when the coil 3 moves with the conveyor roller table 1, the conical surface makes rolling / sliding contact with the coil 3. Utilizing the guiding effect of the conical surface, the coil 3 is gradually guided and constrained within the set coil diameter range to achieve coil diameter shaping.

[0030] Through the above technical solution, the limiting component includes a roller and a conical head. On the one hand, the limiting component has a compact structure, does not occupy extra space, and does not affect the normal conveying of the wire. On the other hand, the conical surface of the conical head contacts the coil, and the contact surface is smooth and the transition is natural, which can avoid scratching or abrading the surface of the wire. At the same time, the conical surface has a natural guiding effect, which can smoothly guide the coil back to the correct position and reduce wire jamming, wire tangling, and wire skipping.

[0031] In this embodiment, the limiting members 21 of the two limiting units 2 are offset along the width direction of the conveying roller track 1.

[0032] Specifically, the limiting members 21 of the two limiting units 2 are staggered along the width direction of the conveyor roller 1, meaning that the limiting members 21 of the left limiting unit 2 and the right limiting unit 2 of the conveyor roller 1 are not directly opposite each other in the width direction of the conveyor roller 1, but are offset to each other and arranged in an alternating manner. Along the length direction of the conveyor roller 1, multiple limiting members 21 are alternately arranged on both sides of the conveyor roller 1. When the coil 3 moves forward on the conveyor roller 1, the left limiting member 21 and the right limiting member 21 alternately and segmentally limit and guide the coil 3, so that the coil 3 is gradually and smoothly constrained to the target coil diameter during the movement, avoiding instantaneous concentrated force.

[0033] Through the above technical solution, the limiting components of the two limiting units are staggered. On the one hand, the left and right staggered limiting makes the limiting more stable. On the other hand, the staggered arrangement can prevent the coil from being "pinched" between the left and right limiting components.

[0034] In this embodiment, each of the aforementioned limiting members 21 is provided with a first driving member (not shown in the figure), which is used to drive the limiting member 21 to adjust its position along the width direction of the conveying roller 1.

[0035] Specifically, the first driving component provides power to the limiting component 21, which can drive the limiting component 21 to move along the width direction of the conveyor roller to achieve individual adjustment of the limiting position. By independently driving the corresponding limiting component 21 by the first driving component, each limiting component 21 can be individually adjusted in terms of extension amount or position along the width direction of the conveyor roller, thereby realizing segmented, refined constraint and shaping of the coil diameter at different positions and sections of the coil 3.

[0036] With the above technical solution, each limit component is equipped with a first driving component. On the one hand, the first driving component can realize the automatic adjustment of the limit component, which is convenient for online adjustment and quick specification change. On the other hand, the degree of automation is high and it can be used in conjunction with the control unit to realize the automatic adjustment of the limit position.

[0037] In this embodiment, two monitoring units 4 and a control unit 5 are also included. The two monitoring units 4 are used to monitor whether the coil 3 on the conveyor roller 1 exceeds the preset area on both sides along the width direction of the conveyor roller 1. The position of each monitoring unit 4 along the width direction of the conveyor roller 1 is adjustable. The control unit 5 is electrically connected to the limiting unit 2 and the monitoring unit 4, and is used to control the limiting unit 2 according to the data monitored by the monitoring unit 4 so that the coil 3 on the conveyor roller 1 is located on its respective preset trajectory on both sides along the width direction of the conveyor roller 1.

[0038] Specifically, the monitoring unit 4 is used to detect the position of the coil 3 in the width direction of the conveyor roller 1 in real time, and to determine whether the coil exceeds the set range. The detection position can be adjusted according to the coil diameter requirements. The control unit 5 receives the signal from the monitoring unit 4 and outputs control commands according to the detection results to automatically adjust the position of the limit unit 2.

[0039] Based on the above-mentioned wire coil diameter adjustment device, in step S1 of the above-mentioned wire coil diameter adjustment method, the position of the above-mentioned monitoring unit 4 is adjusted so that the positions of the above-mentioned two monitoring units 4 can monitor whether the coil 3 on the above-mentioned conveying roller 1 exceeds the preset area on both sides along the width direction of the above-mentioned conveying roller 1. In step S2 of the above-mentioned wire coil diameter adjustment method, the monitoring unit 4 is turned on, and the monitoring unit 4 monitors the real-time position of the coil 3 on the conveying roller 1 along the width direction of the conveying roller 1. If the real-time position exceeds the preset area, the position of the limiting unit 2 is adjusted until the real-time position does not exceed the preset area.

[0040] Specifically, the monitoring unit 4 detects the lateral position of the coil 3 in real time, and the control unit 5 automatically adjusts the limit unit 2 according to the monitoring results, forming a real-time monitoring-automatic adjustment-closed-loop control, so that the coil is always kept within the set coil diameter range, and the coil diameter is automatically, accurately and stably controlled.

[0041] Step S1 includes the following sub-steps: S11, Transmitting the contractually required tonnage, package length, and wire inner and outer diameter information to the secondary system; S12, In the secondary system, matching relevant processes according to the wire's execution standard, grade, and specifications; S13, Transmitting the wire feeding pinch roll or wire feeding signal to the secondary system; S14, According to the set rolling speed and the wire feeding pinch roll or wire feeding signal, the first and third cone tips of the intelligent centering roller device automatically move from their initial positions to their limit positions within the specified time. When the cone tip reaches the limit position, the distance between the cone tip and the end of the roller body where the cone tip is located is (roller body length - outer ring / 2 - inner ring / 2) / 2; S15, The laser positioning device is activated. S16. The alarm system is implemented, and intelligent calibration is performed based on the left and right deviation of the roll shape. If the deviation is left, the 3rd and 5th sections of the cone tip are activated for automatic adjustment; if the deviation is right, the 2nd, 4th, and 6th sections of the cone tip are activated for automatic adjustment. At the same time, the relevant information is transmitted to the secondary system. After intervention in the spinneret swing function and spinneret advance amount optimization, the process proceeds to S14. If the laser positioning device does not alarm, production is directly organized. If the laser positioning device alarms, the process proceeds to step S14 to continue optimization (roller body length - actual outer ring / 2 - actual inner ring / 2). At the same time, the process proceeds to step S11 to verify the contract requirements. If the contract requirements are met, production continues. If the contract requirements are not met, the process continues to adjust until there are no alarms.

[0042] The contract requirements regarding tonnage, packing length, and wire inner and outer diameter are automatically transmitted from the sales system to the secondary system. The furnace batch number information is collected and verified via the furnace entry signal camera to determine the billet tonnage. The ring shape can be automatically adjusted based on the cone tip of the centering roller device and optimized in conjunction with a laser centering alarm device. The arrival time is calculated as: distance from the mill exit to the wire feeding or pre-wire feeding roller / rolling speed + length of the first wire feeding section / roller speed. The secondary system automatically determines and optimizes contract requirements through data interconnection. This effectively achieves cost reduction while meeting downstream customers' needs for high-efficiency, low-cost, and low-waste production, realizing customized needs, improving resource utilization, and reducing carbon emissions.

[0043] The above technical solution also includes a monitoring unit and a control unit, realizing integrated monitoring and adjustment, eliminating the need for frequent manual adjustments, reducing human intervention, and improving the intelligence level of the production line.

[0044] In this embodiment, each of the monitoring units 4 includes a laser emitter 41 and a laser receiver 42 arranged at intervals along the length of the conveyor roller. The laser emitter 41 is used to emit laser light, and the laser receiver 42 is used to receive laser light.

[0045] Specifically, the laser emitter 41 is a transmitting component used to emit detection laser. The laser receiver 42 is a receiving component used to receive the laser emitted by the laser emitter 41. By controlling the laser's on / off state, the detection coil is used to determine whether it is blocking the laser or whether it has exceeded a preset area. The laser emitter 41 and the laser receiver 42 are arranged opposite each other along the length of the conveyor rollers, forming a laser detection light curtain. When the coil 3 exceeds the preset area during conveying, it blocks the laser, and the laser receiver 42 cannot receive the laser signal. Based on this, the control unit 5 determines the coil offset and automatically adjusts the limit unit 2 to correct the deviation.

[0046] The monitoring unit, which includes a laser transmitter and a laser receiver, achieves high accuracy and fast response through the above technical solution. On the one hand, the laser detection does not contact the wire, does not scratch or interfere with the coil transmission.

[0047] In this embodiment, each of the laser emitters 41 is provided with a second driving member (not shown in the figure), which is used to drive the laser emitter 41 to adjust its position along the width direction of the conveyor roller 1. Each of the laser receivers 42 is provided with a third driving member (not shown in the figure), which is used to drive the laser receiver 42 to adjust its position along the width direction of the conveyor roller 1.

[0048] Specifically, the second driving component drives the laser emitter 41 to move along the width direction of the conveyor roller 1 to adjust the detection position. The third driving component drives the laser receiver 42 to move along the width direction of the conveyor roller 1 to adjust the detection position. The second and third driving components independently drive the laser emitter 41 and the laser receiver 42 to move along the width direction of the conveyor roller 1, allowing the laser detection area to be precisely adjusted according to different diameter requirements and ensuring that the laser emitter 41 and the laser receiver 42 are always aligned, achieving reliable detection.

[0049] With the above scheme, the laser emitter is equipped with a second driving component and the laser receiver is equipped with a third driving component. On the one hand, the detection area can be automatically adjusted to adapt to the detection needs of different specifications of wires and different coil diameters. On the other hand, the degree of automation is high, and it can be used in conjunction with the control unit to realize automatic adjustment of the detection position.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
