[0051] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0052] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0053] Figure 1 A flowchart of a steel compressive tension control method provided by the present invention is shown.

[0054] like Figure 1 As shown in S101, this invention discloses a method for controlling steel compressive tension, comprising:

[0055] S101: The detection device acquires the steel tension during product processing according to a preset acquisition frequency, determines the tension detection data, and uploads the tension detection data to the computer.

[0056] S102, the computer compares the tension detection data with the preset tension range threshold interval to obtain tension comparison data, and generates a wind pressure adjustment formula based on the tension comparison data, and sends the wind pressure adjustment formula to the control device; the wind pressure adjustment formula includes the target wind pressure and the adjustment rate;

[0057] S103, the control device converts the air pressure adjustment formula into a control signal and sends the control signal to the pneumatic box;

[0058] S104, the pneumatic box adjusts the fan pressure according to the control signal, collects the steel tension under the action of the air pressure, and obtains tension feedback data;

[0059] S105, based on the analysis of tension feedback data, when the tension feedback data is not within the preset tension range threshold range, the fan pressure is readjusted based on the tension feedback data;

[0060] S106, when the tension feedback data is within the preset tension range threshold range, repeat steps S101-S105.

[0061] According to embodiments of the present invention, such as Figure 5 As shown, the detection device sends the acquired tension detection data to the control device, which then uploads it to the computer. The computer compares the received tension detection data with a preset tension range threshold. When the tension detection data is outside the preset tension range threshold, it calculates tension comparison data and generates a pressure adjustment formula containing the target air pressure and adjustment rate. This pressure adjustment formula is then sent to the control device. The control device uses a D / A converter to convert the target air pressure and adjustment rate in the pressure adjustment formula into analog electrical signals (voltage or current signals), obtaining a control signal, which is then sent to the pneumatic box. The pneumatic box adjusts the valve opening and closing size of the pneumatic valve according to the received control signal, thereby adjusting the fan pressure. This adjusts the strength of the processed product adsorbed on the suction plate connected to the fan, changing the friction between the product and the transmission surface, and stabilizing the tension of the product within a certain range during processing. For example, increasing the fan pressure increases the friction between the product and the transmission surface, increasing the product's tension and pulling force.

[0062] The detection device, typically a tension sensor, is installed on the product processing equipment to detect the steel tension during processing. The processed product can be the inner ply of a tire. Based on the product processing speed, a corresponding preset acquisition frequency is selected to control the detection device to acquire the steel tension during processing. Considering tension fluctuations during processing, a preset tension range threshold is determined based on the target tension corresponding to the product type and a preset tension fluctuation value set by a person skilled in the art for that product type. Based on the relationship between the tension detection data and the maximum and minimum values ​​within the preset tension range threshold, a wind pressure adjustment formula is generated. After converting the wind pressure adjustment formula into an analog electrical signal, the wind pressure of the blower is adjusted, thereby changing the friction between the product and the transmission surface and adjusting the steel tension of the product. Simultaneously, after the blower wind pressure adjustment is completed, the steel tension during product processing is acquired again through the detection device to determine tension feedback data. When the tension feedback data is not within the preset tension range threshold, the blower wind pressure is adjusted again to stabilize the steel tension within a certain range during product processing, thereby improving the processing quality of the product.

[0063] like Figure 6-8 The figures shown are schematic diagrams illustrating the changes in steel tension with processing time during the processing of various products under tension control off. Figure 9-12The figures shown are schematic diagrams illustrating the changes in steel tension with processing time for various processed products under tension control. Figure 13 As shown, the comparison reveals that after tension control is activated, the steel tension of the product remains stable within a certain fluctuation range during processing, with minimal tension fluctuation. C60-235BST, B60-30ST, B33-46-25HE, new C36-77-22HT, new B45-225HT 396, B45-20CH 396, and new B33-77-22CHT are product models named by those skilled in the art for different processed products.

[0064] According to an embodiment of the present invention, it further includes:

[0065] The control signal is either a voltage signal or a current signal.

[0066] It should be noted that the pneumatic box is equipped with a proportional valve. The proportional valve adjusts the valve core opening through voltage or current signals. Therefore, it is necessary to use a control device to convert the air pressure adjustment formula into a control signal composed of voltage or current signals, and then send the control signal to the pneumatic box.

[0067] According to an embodiment of the present invention, it further includes:

[0068] The control device converts the air pressure adjustment formula into a control signal via D / A conversion.

[0069] It should be noted that since the wind pressure adjustment formula is stored in the storage unit of the control device in the form of a digital signal, while the actuators in the system (such as variable frequency fans, pneumatic valves, etc.) can only recognize analog signals, the signal form of the wind pressure adjustment formula needs to be converted by the D / A (digital-to-analog) conversion module of the control device. This D / A conversion module will convert the discrete values ​​in the wind pressure adjustment formula into continuously changing analog electrical signals (such as 4-20mA current signals or 0-10V voltage signals) proportionally.

[0070] According to an embodiment of the present invention, it further includes:

[0071] The preset sampling frequency is dynamically adjusted according to the product processing speed.

[0072] It should be noted that the system selects the corresponding preset sampling frequency within the set preset sampling frequency range (e.g., 10ms-1s) according to the product processing speed. Different product processing speeds have corresponding preset sampling frequencies. The faster the product processing speed, the faster the corresponding preset sampling frequency.

[0073] Figure 2 A flowchart of the wind pressure adjustment formula generation method provided by the present invention is shown.

[0074] like Figure 2 As shown, according to an embodiment of the present invention, tension detection data is compared with a preset tension range threshold interval to obtain tension comparison data, and a wind pressure adjustment formula is generated based on the tension comparison data, including:

[0075] S201, when the tension detection data is within the preset tension range threshold range, the tension comparison data is determined to be 0;

[0076] S202, when the tension detection data is less than the minimum value of the preset tension range threshold interval, calculate the data difference between the minimum value of the preset tension range threshold interval and the tension detection data, and determine the tension comparison data;

[0077] S203, when the tension detection data is greater than the maximum value of the preset tension range threshold interval, calculate the data difference between the maximum value of the preset tension range threshold interval and the tension detection data to determine the tension comparison data;

[0078] S204 generates a wind pressure adjustment formula based on tension comparison data and preset tension range threshold intervals.

[0079] It should be noted that the preset tension range threshold is set by the system based on a pre-defined target tension combined with a preset tension fluctuation value, for example, the target tension ±1N. Due to data fluctuations, when the tension detection data is within the preset tension range threshold, it falls within the data fluctuation range, and no tension adjustment is required; the output tension comparison data is 0. Conversely, when the tension detection data is not within the preset tension range threshold, the tension comparison data is calculated based on the maximum or minimum value of the preset tension range threshold.

[0080] The system pre-sets the target tension as the midpoint of a preset tension range threshold interval. It prioritizes the midpoint of this interval as the optimal adjustment parameter, generating a wind pressure adjustment formula that includes the target wind pressure and adjustment rate. Additionally, tension comparison data can be used as the minimum tension adjustment value to ensure that the actual tension change during adjustment at least meets the tension comparison value.

[0081] According to an embodiment of the present invention, it further includes:

[0082] When the tension comparison data is 0, no wind pressure adjustment formula is generated.

[0083] It should be noted that when the tension comparison data is 0, it means that the tension detection data obtained at the moment is within the tension data fluctuation range, and no tension adjustment is required, that is, no wind pressure adjustment formula needs to be generated.

[0084] Figure 3 A flowchart of the method for adjusting the wind pressure of a fan by means of a control signal provided by the present invention is shown.

[0085] like Figure 3 As shown, according to an embodiment of the present invention, adjusting the fan pressure according to a control signal includes:

[0086] S301, compare the absolute value of the tension comparison data |P| with the first preset tension deviation threshold P. a Second preset tension deviation threshold P b Compare;

[0087] S302, when |P|≥P b At that time, adjust the fan pressure according to the first-level adjustment rate;

[0088] S303, when P a <|P|≤P b At that time, the fan pressure is adjusted according to the second-level adjustment rate;

[0089] S304, when |P| < |P| a At that time, the fan pressure should be adjusted according to the three-level adjustment rate;

[0090] Wherein, the first preset tension deviation threshold P a Less than the second preset tension deviation threshold P b .

[0091] It should be noted that the first preset tension deviation threshold P a Second preset tension deviation threshold P b All settings are determined by those skilled in the art based on actual needs. The first preset tension deviation threshold P a For a smaller tension deviation value, the second preset tension deviation threshold P b This represents a relatively large tension deviation value. Based on the absolute value of the tension comparison data |P|, it is compared with the first preset tension deviation threshold P. a Second preset tension deviation threshold P b Based on the relationship between the magnitudes, the pneumatic box employs a graded adjustment strategy to regulate the fan pressure. The first-level adjustment rate is the maximum adjustment rate of the proportional valve, typically ≥0.2MPa / s; the third-level adjustment rate is the minimum adjustment rate of the proportional valve, typically ≤0.05MPa / s; and the second-level adjustment rate is determined by the system based on the absolute value |P| of the tension comparison data, selecting between the first-level and third-level adjustment rates.
