Description

Technical Field

[0001] This utility model belongs to the technical field of enameled wire production line, specifically relating to a constant temperature device for annealing cooling water in an enameled wire production line. Background Technology

[0002] In the production of enameled wire, annealing is one of the key steps. After annealing, the copper wire needs to be rapidly cooled in cooling water to ensure its mechanical and electrical properties. The temperature of the cooling water has a significant impact on the quality of the copper wire; excessively high temperatures can cause the copper wire to soften, while excessively low temperatures may induce internal stress. Therefore, maintaining the cooling water temperature within a suitable range is crucial.

[0003] Currently, the cooling methods commonly used in enameled wire production lines often rely on ambient temperature or simple cooling water circulation, making it difficult to accurately control the temperature of the cooling water, resulting in unstable copper wire quality. Secondly, when cooling the enameled wire production line, it is inconvenient to open the box cover, and when the enameled wire production line is small, opening the entire box cover directly will cause the water temperature to drop rapidly. Utility Model Content

[0023] Specifically, the chiller 41, heater 42, PLC controller 43, control switch 44, and temperature sensor 45 are all electrically connected to the power supply via wires.

[0024] By adopting the above technical solution, the structure can enable the refrigerator 41, heater 42, PLC controller 43, control switch 44 and temperature sensor 45 to function normally.

[0025] In this embodiment, when cooling the enameled wire production line, when the annealed copper wire enters the cooling box 1, the temperature sensor 45 monitors the temperature of the cooling water in real time. If the temperature is below 60 degrees, the temperature sensor 45 converts the temperature signal into an electrical signal and transmits it to the PLC controller 43. The PLC controller 43 controls the heater 42 to work through the control switch 44, heating the cooling water to 60 degrees. If the temperature is above 63 degrees, the temperature sensor 45 converts the temperature signal into an electrical signal and transmits it to the PLC controller 43. The PLC controller 43 controls the chiller 41 to work through the control switch 44, cooling the cooling water to 57 degrees. In this way, the temperature of the cooling water in the cooling box 1 can always be maintained within the range of 60±3 degrees.

[0026] Example 2

[0027] The difference between this embodiment and Embodiment 1 is that the lid fixing mechanism 5 includes a locking block 51, a fixing hole 55, a locking seat 56, a locking groove 57, and a fixing component 58. A locking block 51 is provided on the other side of the lid body 6, and a fixing hole 55 is provided on the side of the locking block 51. A locking seat 56 is provided at the upper end of the side of the cooling box 1, and a locking groove 57 is provided on the side of the locking seat 56. The fixing component 58 is provided inside the side of the locking groove 57.

[0028] By adopting the above technical solution, when fixing the box cover body 6, the card block 51 is inserted into the card slot 57 on the side of the card seat 56, and then the fixing component 58 and fixing hole 55 are used to fix the box cover body 6.

[0029] Specifically, the fixing component 58 includes a fixing rod 581 and a spring 584. The spring 584 is disposed inside the side of the slot 57, and the fixing rod 581 is disposed at the other end of the spring 584.

[0030] By adopting the above technical solution, before fixing the box cover body 6, press the fixing rod 581, the fixing rod 581 compresses the spring 584 and embeds it into the inside of the card seat 56. At this time, insert the card block 51 into the card groove 57 on the side of the card seat 56, the spring 584 rebounds, thereby driving the fixing rod 581 to be inserted into the inside of the fixing hole 55, so as to fix the box cover body 6.

[0031] Specifically, the fixing component 58 also includes an adjusting block 582 and an adjusting groove 583. The adjusting block 582 is provided on the side of the fixing rod 581, and the adjusting groove 583 corresponding to the adjusting block 582 is provided on the side of the card holder 56.

[0032] By adopting the above technical solution, when the box cover body 6 is opened, the adjusting block 582 inside the sliding adjusting groove 583 drives the fixing rod 581 to slide out from the inside of the fixing hole 55, and the box cover body 6 can be opened at this time.

[0033] Specifically, the lid fixing mechanism 5 includes a through groove 52, a sealing cover 53, and a pull ring 54. The sealing cover 53 is provided at the upper end of the lid body 6, the through groove 52 is provided inside the lid body 6, and the pull ring 54 is provided at the upper end of the sealing cover 53.

[0034] By adopting the above technical solution, when used on a smaller enameled wire production line, pulling the pull ring 54 causes the sealing cover 53 to slide out from inside the through groove 52, at which point the sealing cover 53 can be opened.

[0035] In this embodiment, before fixing the box cover body 6, press the fixing rod 581. The fixing rod 581 compresses the spring 584 and embeds into the inside of the card seat 56. Then, insert the card block 51 into the card groove 57 on the side of the card seat 56. The spring 584 rebounds, thereby driving the fixing rod 581 to be inserted into the inside of the fixing hole 55 to fix the box cover body 6. When opening the box cover body 6, slide the adjusting block 582 inside the adjusting groove 583. The adjusting block 582 drives the fixing rod 581 to slide out from the inside of the fixing hole 55. At this time, the box cover body 6 can be opened. When used on a smaller enameled wire production line, pull the pull ring 54. The pull ring 54 drives the sealing cover 53 to slide out from the inside of the through groove 52. At this time, the sealing cover 53 can be opened.

[0036] The refrigeration unit 41 in this utility model is a previously disclosed technology, and the selected model is KS-04X60Dg.

[0037] The heater 42 in this utility model is a previously disclosed technology, and the selected model is NDYC-2502.

[0038] The PLC controller 43 in this utility model is a publicly available technology, and the selected model is Siemens S7-300.

[0039] The temperature sensor 45 in this invention is a publicly available technology, and the selected model is PT100.

[0040] The working principle and usage process of this utility model are as follows: When using this utility model to cool down the enameled wire production line, when the annealed copper wire enters the cooling tank 1, the temperature sensor 45 monitors the temperature of the cooling water in real time. If the temperature is below 60 degrees Celsius, the temperature sensor 45 converts the temperature signal into an electrical signal and transmits it to the PLC controller 43. The PLC controller 43 then controls the heater 42 to work via the control switch 44, heating the cooling water to 60 degrees Celsius. If the temperature is above 63 degrees Celsius, the temperature sensor 45 converts the temperature signal into an electrical signal and transmits it to the PLC controller 43. The PLC controller 43 then controls the chiller 41 to work via the control switch 44, cooling the cooling water to 57 degrees Celsius. In this way, the temperature of the cooling water in the cooling tank 1 can be kept constant. The temperature is maintained within the range of 60±3 degrees. Before fixing the box cover body 6, press the fixing rod 581. The fixing rod 581 compresses the spring 584 and embeds into the inside of the card seat 56. Then, insert the card block 51 into the card groove 57 on the side of the card seat 56. The spring 584 rebounds, thereby driving the fixing rod 581 to be inserted into the inside of the fixing hole 55 to fix the box cover body 6. When opening the box cover body 6, slide the adjusting block 582 inside the adjusting groove 583. The adjusting block 582 drives the fixing rod 581 to slide out from the inside of the fixing hole 55. At this time, the box cover body 6 can be opened. When used on a smaller enameled wire production line, pull the pull ring 54. The pull ring 54 drives the sealing cover 53 to slide out from the inside of the through groove 52. At this time, the sealing cover 53 can be opened.
