Description

Technical Field

[0001] This utility model belongs to the field of copper wire annealing technology, specifically relating to a copper wire annealing box. Background Technology

[0002] In numerous industries such as electrical, electronic, and communications, copper wire, with its excellent electrical, thermal, and mechanical properties, has become an indispensable basic material. Annealing, as a key process for improving copper wire performance, effectively eliminates internal stress generated during processing, improving its toughness and ductility. Maintaining stable tension during copper wire annealing is crucial for ensuring annealing quality. Excessive tension can easily cause the copper wire to stretch and deform, even breaking; insufficient tension will lead to loosening and knotting, affecting annealing uniformity and production continuity.

[0003] However, existing copper wire annealing equipment has significant shortcomings in tension detection and feedback control. For example, the utility model patent with authorization announcement number CN221501188U relies on turning the handle to adjust the height of the adjusting wheel, thereby manually adjusting the tension of the copper wire. This structure cannot monitor changes in copper wire tension in real time, nor can it automatically adjust the winding and unwinding speed of the copper wire during production to ensure that the tension of the copper wire remains stable within a suitable range. It cannot meet the needs of high-speed production, resulting in quality defects in the copper wire due to unstable tension during annealing, reducing production efficiency and increasing scrap rate. Other equipment, although using sensor detection, has an unreasonable detection structure design, is susceptible to external interference, and has poor detection accuracy, failing to provide a reliable basis for adjusting the winding and unwinding speed. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a copper wire annealing box that solves the shortcomings of existing copper wire annealing equipment in tension detection and feedback control, as well as the problem of lagging manual adjustment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a copper wire annealing box, comprising a box body, with an inlet slot and an outlet slot respectively opened at both ends of the box body. A guide wheel is rotatably mounted inside the box body on each side of the inlet and outlet slots. A preheating wheel and an electrode wheel are rotatably mounted inside the box body between the two guide wheels. A wire take-up and release speed monitoring mechanism, a control mechanism, and a solenoid valve are mounted on the box body. The wire take-up and release speed monitoring mechanism includes a bracket fixed to the outside of the box body. An angle sensor is mounted on the bracket. The rotating shaft is connected to the main shaft via a coupling. The main shaft rotates through the housing. A first-stage guide rod holder is clamped on the main shaft on both the inner and outer sides of the housing. The two first-stage guide rod holders respectively clamp a first-stage connecting rod and a second-stage connecting rod. A second-stage guide rod holder and a third-stage guide rod holder are respectively clamped on the first-stage connecting rod and the second-stage connecting rod. One end of the second-stage guide rod holder is attached to a tension spring, and the other end of the tension spring is attached to a fixing pin. The fixing pin is fixed to the housing. A support wheel is rotatably mounted on the third-stage guide rod holder, and the support wheel is positioned between the preheating wheel and the electrode wheel.

[0006] The beneficial effects of this utility model are as follows: when the copper wire passes over the lower side of the support wheel, as the tension of the copper wire changes and the elastic pull of the tension spring works together, the support wheel moves up and down, driving the rotation shaft of the angle sensor to rotate. The tension of the copper wire can be accurately obtained by the angle change information detected by the angle sensor, so that the solenoid valve can automatically control the winding and unwinding speed of the copper wire, avoiding the copper wire from becoming loose, knotted or stretched and deformed.

[0007] To ensure the stability of the spindle when mounted on the housing;

[0008] As a further improvement to the above technical solution: the housing is provided with slots and bolt holes for mounting bearing seats, and the main shaft is rotatably mounted in the bearing seats.

[0009] The beneficial effect of this improvement is that the spindle is stably mounted on the housing with the support of the bearing housing.

[0010] To ensure the stability of the angle sensor installation;

[0011] As a further improvement to the above technical solution: the bracket is a channel steel structure, and the two flanges of the bracket are respectively connected to the housing and the angle sensor.

[0012] The beneficial effect of this improvement is that the bracket can be stably installed on the housing, ensuring stable support for the angle sensor.

[0013] In order to enable the tension spring to provide effective elastic tension to the support wheel;

[0014] As a further improvement to the above technical solution: the axis of the support wheel is parallel to the axis of the main shaft, and the connecting rod one and the connecting rod two are respectively arranged on both sides of the main shaft.

[0015] The beneficial effect of this improvement is that the upward elastic tension provided by the tension spring can cause the support wheel to press down tightly against copper wires with different tensions.

[0016] To ensure the heating effect of the preheating wheel and electrode wheel on the copper wire;

[0017] As a further improvement to the above technical solution: two guide wheels are horizontally and rotatably installed in the housing between the preheating wheel and the electrode wheel, and both the guide wheels are positioned above the preheating wheel and the electrode wheel.

[0018] The beneficial effects of this improvement are: the setting of the second guide wheel can effectively increase the contact area between the copper wire and the preheating wheel and the electrode wheel, thereby ensuring the heating effect of the preheating wheel and the electrode wheel on the copper wire.

[0019] To ensure the stability of the contact between the support wheel and the copper wire;

[0020] As a further improvement to the above technical solution: the support wheel is located between the two guide wheels, and the support wheel is located below the guide wheels.

[0021] The beneficial effect of this improvement is that the copper wire, supported by the two guide wheels, can pass around the underside of the support wheel and make stable contact with the support wheel.

[0022] In order to achieve automatic control of copper wire tension;

[0023] As a further improvement to the above technical solution: the control mechanism includes a transmitter, a PLC, and two motor controllers. The transmitter in the control mechanism is electrically connected to an angle sensor, and the two motor controllers in the control mechanism are electrically connected to a wire-laying motor and a wire-retrieving motor, respectively.

[0024] The beneficial effects of this improvement are as follows: the transmitter in the control mechanism processes the electrical signal from the angle sensor and sends it to the PLC, which then controls the winding and unwinding speed of the copper wire through the motor controller according to the preset program.

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way. Example

[0031] like Figure 1As shown in Figure 3: A copper wire annealing box includes a box body 1. An inlet groove 2 and an outlet groove 3 are respectively opened at both ends of the box body 1. A wire guide wheel 4 is rotatably installed inside the box body 1 on each side of the inlet groove 2 and outlet groove 3. A preheating wheel 6 and an electrode wheel 22 are rotatably installed inside the box body 1 between the two wire guide wheels 4. A winding / unwinding speed monitoring mechanism 7, a control mechanism 8, and a solenoid valve 9 are installed on the box body 1. The winding / unwinding speed monitoring mechanism 7 includes a bracket 10, which is fixed to the outside of the box body 1. An angle sensor 11 is installed on the bracket 10. The rotating shaft of the angle sensor 11 is connected to a main shaft 13 via a coupling 12. The main shaft 13 rotates through the box body 1. The main shafts 13 on both the inner and outer sides of the box body 1... Each of the two optical rod clamping seats 14 is clamped together. Connecting rod 15 and connecting rod 29 are clamped together respectively. Optical rod clamping seat 26 and optical rod clamping seat 3 20 are clamped together on connecting rod 15 and connecting rod 29 respectively. One end of a connecting spring 17 is attached to optical rod clamping seat 26, and the other end of the spring 17 is attached to a fixing pin 18, which is fixed to the housing 1. A support wheel 21 is rotatably mounted on optical rod clamping seat 3 20. The support wheel 21 is positioned between the preheating wheel 6 and the electrode wheel 22. When the copper wire passes over the underside of the support wheel 21, the support wheel 21 moves up and down, causing the angle sensor 11 to rotate, due to changes in the tension of the copper wire and the elastic pull of the spring 17. The rotation of the shaft, along with the angle change information detected by the angle sensor 11, accurately determines the tension of the copper wire. This allows the solenoid valve 9 to automatically control the winding and unwinding speed of the copper wire, preventing slack, knotting, or stretching deformation. The housing 1 has slots and bolt holes for mounting bearing seats. The main shaft 13 is rotatably mounted in the bearing seats and stably mounted on the housing 1 with the support of the bearing seats. The bracket 10 is a channel steel structure, with its two flanges connected to the housing 1 and the angle sensor 11 respectively. The bracket 10 can be stably mounted on the housing 1, ensuring stable support for the angle sensor 11. The axis of the support wheel 21 is parallel to the axis of the main shaft 13. The connecting rod 15 and connecting rod 19... The support wheel 21 is positioned on both sides of the main shaft 13. The upward elastic force provided by the tension spring 17 allows the support wheel 21 to press down firmly onto copper wires with different tensions. Two guide wheels 5 are horizontally spaced and rotatably installed inside the housing 1 between the preheating wheel 6 and the electrode wheel 22. Both guide wheels 5 and guide wheels 4 are positioned above the preheating wheel 6 and the electrode wheel 22. The placement of guide wheels 5 effectively increases the contact area between the copper wire and the preheating wheel 6 and the electrode wheel 22, thereby ensuring the heating effect of the preheating wheel 6 and the electrode wheel 22 on the copper wire. The support wheel 21 is located between the two guide wheels 5 and below them. Supported by the two guide wheels 5, the copper wire can pass under the support wheel 21 and maintain stable contact with it.The control mechanism 8 includes a transmitter, a PLC, and two motor controllers. The transmitter in the control mechanism 8 is electrically connected to the angle sensor 11. The two motor controllers in the control mechanism 8 are electrically connected to the wire feeding motor and the wire take-up motor, respectively. The transmitter in the control mechanism 8 processes the electrical signal from the angle sensor 11 and sends it to the PLC. The PLC then controls the wire feeding and take-up speeds of the copper wire through the motor controllers according to a preset program.

[0032] The working principle of this technical solution is as follows: The copper wire to be annealed is inserted into the wire inlet groove 2 at one end of the housing 1, and then wound downwards from the upper side of the first guide wheel 4 on one side of the wire inlet groove 2 to the lower side of the preheating wheel 6. Then it is wound upwards to the upper side of the first guide wheel 5, and then wrapped around the support wheel 21 from below. Next, it is wound upwards to the second guide wheel 5, then downwards to the electrode wheel 22, and then wrapped around the second guide wheel 4 from the upper side of the first guide wheel 4. Finally, it is passed out from the wire outlet groove 3, and the end of the copper wire is fixed on the take-up device of the take-up motor. During the wire threading process, it is ensured that the copper wire is in close contact with each guide wheel, the preheating wheel 6, the electrode wheel 22 and the support wheel 21, and that the running trajectory of the copper wire is smooth without twisting or knotting.

[0033] The pay-off and take-up motors are started to allow the copper wire to begin being fed and wound at a set initial speed. Simultaneously, the heating devices of the preheating wheel 6 and electrode wheel 22 are activated to anneal and heat the copper wire. During equipment operation, the pay-off and take-up speed monitoring mechanism 7 monitors the tension of the copper wire in real time. When the tension of the copper wire changes, the support wheel 21 moves up and down under the elastic pull of the tension spring 17, driving the main shaft 13 to rotate. This causes the rotation axis of the angle sensor 11 to change angle. The angle sensor 11 converts the detected angle change information into an electrical signal, which is transmitted to the PLC in the control mechanism 8 through a transmitter. The PLC analyzes and processes the electrical signal according to a preset program to determine whether the tension of the copper wire is within the set threshold range. If the tension exceeds the threshold, the PLC automatically adjusts the speed of the pay-off and take-up motors through the motor controller to balance the pay-off and take-up speeds of the copper wire, thereby ensuring that the tension of the copper wire remains stable within a suitable range.
