[0022] Based on the automatic control device for the water quenching process in the embodiment of the present invention, the residual torsion of the cord caused by the water quenching process can be accurately obtained and accurately corrected, so that a torsionally stable and qualified steel cord can be obtained, thereby improving product quality and making the calendering and cutting of the tire factory smooth and without warping, which can generate great economic benefits.

[0023] In a specific implementation of the embodiment of the present invention, Figure 2 As shown, the first tank driving mechanism and the second tank driving mechanism have the same structure, both comprising: a driving motor 12, a first gear 13, a second gear 14, a shaft 16, a bearing 15 and a roller 8; The driving motor 12 is connected to the controller 17, and its output shaft is connected to the first gear 13; The first gear 13 is meshed with the second gear 14; The second gear 14 is connected to the shaft 16; The shaft 16, the bearing 15 and the roller 8 are arranged in sequence and coaxially.

[0024] When the driving motor 12 receives the control signal sent by the controller 17, it drives the first gear 13 to rotate, the first gear 13 drives the second gear 14 to rotate, and the second gear 14 drives the shaft 16 and the bearing 15 to rotate, finally realizing the driving roller 8 to move along the track 3.

[0025] In a specific implementation of the embodiment of the present invention, the first slot driving mechanism is located below the first clamping plate 2. The second slot driving mechanism is located below the second clamping plate.

[0026] In a specific implementation of the embodiment of the present invention, the first retaining plate 2 is installed in the middle position of the first slot body 4 ; the second retaining plate is installed in the middle position of the second slot body 7 .

[0027] In a specific implementation of the embodiment of the present invention, the first distance measuring sensor 5 is defined to be located at the second end of the first slot body 4, and the first distance measuring sensor 5 is used to measure the distance between itself and the first end of the first slot body 4. The second distance measuring sensor 6 is defined to be located at the first end of the second slot body 7, and the third distance measuring sensor 10 is located at the second end of the second slot body 7; the second distance measuring sensor 6 is used to measure the distance between itself and the first distance measuring sensor 5; the third distance measuring sensor 10 is used to measure the distance between itself and the first end of the second slot body 7.

[0028] In a specific implementation of the embodiment of the present invention, the first distance measuring sensor 5, the second distance measuring sensor 6 and the third distance measuring sensor 10 are all laser sensors. The three laser sensors need to detect three sets of data, which are the values ​​of the WT1 process (the WT1 process refers to a specific section in the water bath quenching process in the production of steel cord, Water Treatment 1), the AIR process (Austempered Ductile Iron) and the WT2 process (the WT2 process refers to a specific section in the water bath quenching process in the production of steel cord, Water Treatment 2): 1. If Figure 1 As shown, the first laser sensor is installed on the rightmost side of the first positioning plate. It emits laser light to the leftmost side of the first slot body 4, which is reflected back and received by the first laser sensor. After the first laser sensor receives the light, the speed of the light is fixed. By calculating the time, the distance from the first laser sensor to the leftmost side of the first slot body 4 can be obtained, thereby detecting the value of the WT1 process.

[0029] 2 Such as Figure 1 As shown, the second laser sensor is installed at the leftmost side of the second slot 7. It emits laser light to illuminate the first laser sensor, which is reflected back and received by the second laser sensor.

By calculating the time, the distance from the second laser sensor to the first laser sensor can be obtained, thereby detecting the value of the AIR process.

[0030] 3. If Figure 1As shown, the third laser sensor is installed on the rightmost side of the second positioning plate. It emits laser light to the leftmost side of the second slot 7, which is reflected back and received by the third laser sensor. After the third laser sensor receives the light, the speed of the light is fixed. By calculating the time, the distance from the third laser sensor to the leftmost side of the second slot 7 can be obtained, thereby detecting the value of the WT2 process.

[0031] Usually, the WT1 value is between 110 and 130CM, the AIR value is between 350 and 400CM, and the WT2 value is between 40 and 50; The above three parameters with values ​​within the range are input into the controller 17 (in the specific implementation process, the controller 17 can be a PLC controller 17), the actual output data of the laser sensor of the PLC controller 17 generates a corresponding control signal, and drives the corresponding drive motor 12 to adjust the positions of the first slot body 4 and the second slot body 7.

[0032] In a specific implementation of the embodiment of the present invention, a first lifting pump 1 and a second lifting pump 9 are respectively provided above the first tank body 4 and the second tank body 7 for lifting the condensed water from a lower installation position to a higher position for discharge or further treatment.

Implementation

[0034] Set the WT1 value to 120cm, the AIR value to 350cm, and the WT2 value to 40cm and input them into the PLC controller respectively; The analog signal range in the PLC controller is 0 to 27648, corresponding to the laser sensor range of 0 to 5m; Therefore, the analog signal corresponding to the WT1 value is (27648 / 5)*1.2; The analog signal corresponding to the WT2 value is (27648 / 5)*3.5; The analog signal corresponding to the AIR value is (27648 / 5)*0.40; The PLC controller controls the motor to drive the first trough body and the second trough body to move according to the above analog signal and the distance detected by the laser sensor in real time, thereby automatically and accurately adjusting the process.
