AI Technical Summary
In existing technologies, controlling the wire tension by constant air pressure cannot effectively guarantee the flatness of the wires on the fabric surface or avoid the risk of sparse wires in the fabric, especially when the spindle diameter is small and the angular velocity is high, the wire tension varies greatly.
A gradual wind pressure braking system is adopted. By combining the monitoring unit and the wind pressure unit, the wind pressure value and the rate of change of wind pressure are adjusted in real time. The wind pressure is dynamically adjusted according to the spindle speed. The tension and flatness of the wires in the cord layer are monitored. An ultrasonic winding measurement system is used for real-time monitoring and adjustment.
Effectively controlling the wire tension and tension difference within the standard range improves the flatness of the fabric surface, reduces the risk of sparse threads in the fabric, and enhances product quality.

Abstract
Description
Technical Field
[0001] This application relates to the field of tire manufacturing technology, and in particular to a gradual air pressure braking system for adjusting the tension of tire steel wires. Background Technology
[0002] In tire manufacturing, as people's demands for tire safety and comfort performance increase, the uniformity of cord thickness and the smoothness of the cord surface, among other intrinsic tire qualities, are receiving increasing attention. The smoothness of the cord surface is related to the consistency of the tension of the steel wires within the cord. When subjected to external force, the steel wires in the cord are taut. When the instantaneous impact force from a road obstacle exceeds the maximum strength of a particular steel wire, that wire may break, followed by the breakage of other wires, triggering a chain reaction: the carcass cord may burst, causing a zipper-like burst; the belt layer cord may burst. Therefore, controlling the tension of the steel wires is particularly important.
[0003] Steel cord fabric, as the skeleton material, is a major load-bearing component in tires, used to form the tire carcass and belt layers. For the belt layers, their rigidity significantly affects the tire's strength and performance characteristics, including its profile after inflation. The load is borne by each steel wire in the cord fabric, requiring consistent stress on each wire. Therefore, the more uniform the tension of the steel wires in the cord fabric, the better. This means controlling the tension fluctuations of individual steel wires during calendering and minimizing the tension differences between each wire, resulting in a smoother surface between the wires on the calendered cord fabric.
[0004] Currently, the tension of the wire unwinding is controlled by constant air pressure. However, as the diameter of the wire spindle decreases, the angular velocity of the spindle increases, and the tension of the wire unwinding increases. Controlling the tension solely by constant air pressure can easily lead to poor flatness between the wires on the surface of the calendered fabric, increasing the risk of sparse threads in the fabric. Summary of the Invention

[0061] like Figures 1-3 As shown in the figure, a gradual air pressure braking system for adjusting the tension of tire steel wire release according to an embodiment of this application includes:
[0062] The monitoring unit and the wind pressure unit are connected wirelessly.
[0063] The monitoring unit includes:
[0064] The spindle rotation speed acquisition module is used to collect real-time spindle rotation speed data;
[0065] Specifically, the spindle rotation speed acquisition module is preferably a rotation speed sensor;
[0066] The wind pressure unit includes:
[0067] The first control module is used to acquire real-time spindle rotation speed data and set real-time air pressure value based on the real-time spindle rotation speed data.
[0068] The second control module is used to acquire real-time spindle rotation speed data and set the wind pressure change rate based on the real-time spindle rotation speed data.
[0069] Specifically, the first control module is used for:
[0070] A preset wind pressure value matrix A is defined as A(A1,A2,A3,A4), where A1 is the preset first wind pressure value, A2 is the preset second wind pressure value, A3 is the preset third wind pressure value, and A4 is the preset fourth wind pressure value, and A1 < A2 < A3 < A4;
[0071] The first control module is also used to preset the spindle speed matrix B, setting B(B1,B2,B3,B4), where B1 is the preset first spindle speed, B2 is the preset second spindle speed, B3 is the preset third spindle speed, and B4 is the preset fourth spindle speed, and B1 < B2 < B3 < B4;
[0072] The first control module is also used to acquire the real-time spindle rotation speed b, and set the real-time wind pressure value a based on the real-time spindle rotation speed b;
[0073] When B1 < b < B2, the real-time wind pressure value a is set to be greater than the preset fourth wind pressure value A4, i.e., a > A4;
[0074] When B2 < b < B3, the real-time wind pressure value a is set to be between the preset third wind pressure value A3 and the preset fourth wind pressure value A4, i.e., A3 < a < A4;
[0075] When B3 < b < B4, the real-time wind pressure value a is set to be between the preset second wind pressure value A2 and the preset third wind pressure value A3, i.e., A2 < a < A3;
[0076] When b>B4, the real-time wind pressure value a is set to be between the preset first wind pressure value A1 and the preset second wind pressure value A2, i.e., A1<a<A2.
[0077] Specifically, the monitoring unit also includes:
[0078] The first monitoring module is used to collect data on the tension of the steel wires in the fabric layer.
[0079] The second monitoring module is used to collect data on the flatness of the steel wires in the finished fabric layer.
[0080] Specifically, the first monitoring module is preferably a tension sensor;
[0081] Specifically, the second monitoring module is preferably an ultrasonic winding measurement system.
[0082] It is understandable that in the above embodiments, by presetting the spindle speed matrix and the air pressure matrix, the range of air pressure variation is dynamically adjusted according to the real-time speed of the spindle. The angular velocity of the spindle becomes faster and faster (the production line speed remains constant, and the number of steel wire meters required in the same time is fixed), and the wire unwinding tension becomes larger and larger. By dynamically adjusting the air pressure value, large differences in wire unwinding tension are avoided, thereby improving product quality.
[0083] In this embodiment of the application, the second control module is used for:
[0084] A preset wind pressure change rate matrix C is defined as C(C1,C2,C3,C4), where C1 is the preset first wind pressure change rate, C2 is the preset second wind pressure change rate, C3 is the preset third wind pressure change rate, and C4 is the preset fourth wind pressure change rate, and C1 < C2 < C3 < C4;
[0085] The second control module is also used to acquire the real-time spindle rotation speed b, and set the real-time wind pressure change rate c according to the real-time spindle rotation speed b;
[0086] When B1 < b < B2, the real-time wind pressure change rate c is set to the preset fourth wind pressure change rate C4, i.e., c = C4;
[0087] When B2 < b < B3, the real-time wind pressure change rate c is set to the preset third wind pressure change rate C3, i.e., c = C3;
[0088] When B3 < b < B4, the real-time wind pressure change rate c is set to the preset second wind pressure change rate C2, i.e., c = C2;
[0089] When b>B4, the real-time wind pressure change rate c is set to the preset first wind pressure change rate C1, that is, c=C1.
[0090] Specifically, by pre-setting a wind pressure change rate matrix, the change rate is set in different wind pressure value ranges. When the end value of the wind pressure value range is reached, the change stops. The wind pressure change rate is dynamically adjusted according to the real-time rotation speed of the spindle to ensure that the wire tension and the difference in wire tension are within the standard range. This effectively avoids the problem of large differences in wire tension, improves product quality, enhances the flatness of the fabric surface, and reduces the risk of sparse wires in the fabric.
[0091] In this embodiment of the application, the wind pressure unit further includes:
[0092] The first processing module is used to acquire the tension data of the steel wires in the fabric layer and generate the real-time tension difference d of the steel wires in the fabric layer.
[0093] The first compensation module sets the wind pressure change rate compensation coefficient based on the real-time tension difference of the steel wires in the fabric layer.
[0094] Specifically, the first compensation module is used for:
[0095] A preset tension difference matrix D for the steel wires of the fabric layer is defined as D(D1,D2,D3), where D1 is the preset tension difference for the steel wires of the first fabric layer, D2 is the preset tension difference for the steel wires of the second fabric layer, and D3 is the preset tension difference for the steel wires of the third fabric layer, and D1 < D2 < D3;
[0096] The first compensation module is also used to preset the compensation coefficient matrix N, setting N(n1,n2,n3), where n1 is the preset first compensation coefficient, n2 is the preset second compensation coefficient, n3 is the preset third compensation coefficient, and 0.8 < n1 < n2 < n3 < 1;
[0097] The wind pressure change rate compensation coefficient n is set based on the real-time tension difference d of the steel wires in the fabric layer.
[0098] When D1 < d < D2, the wind pressure change rate compensation coefficient n is set to the preset third compensation coefficient n3, and the real-time wind pressure change rate c = n3 * Ci;
[0099] When D2 < d < D3, the wind pressure change rate compensation coefficient n is set to the preset second compensation coefficient n2, and the real-time wind pressure change rate c = n2 * Ci;
[0100] When d>D3, the wind pressure change rate compensation coefficient n is set to the preset first compensation coefficient n1, and the real-time wind pressure change rate c=n1*Ci.
[0101] Specifically, by obtaining the real-time tension difference of the steel wires in the fabric layer, a wind pressure change rate compensation coefficient is set to adjust the real-time wind pressure change in a timely manner. As the tension difference increases, the wind pressure change rate is reduced in a timely manner to avoid excessive tension difference between individual filaments due to excessively rapid wind pressure changes.
[0102] In this embodiment of the application, the wind pressure unit further includes;
[0103] The first correction module is used to obtain the flatness data of the finished fabric layer steel wire and correct the production air pressure value of the next fabric layer steel wire based on the flatness data of the finished fabric layer steel wire.
[0104] Specifically, the first correction module is used for:
[0105] The pre-set finished fabric layer steel wire flatness matrix E is set as E(E1,E2,E3), where E1 is the pre-set first finished fabric layer steel wire flatness, E2 is the pre-set second finished fabric layer steel wire flatness, and E3 is the pre-set third finished fabric layer steel wire flatness.
[0106] The first correction module is also used to preset the correction coefficient matrix M, setting M(m1,m2), where m1 is the preset first correction coefficient, m2 is the preset second correction coefficient, and 1 < m1 < m2 < 1.2;
[0107] Obtain the flatness data e of the finished fabric layer steel wires, and set the correction parameter m based on the finished fabric layer steel wire flatness data e;
[0108] When E1 < e < E2, the correction parameter m is set to the preset first correction coefficient m1, and the corrected wind pressure value A0 = m1 * Ai;
[0109] When E2 < e < E3, the correction parameter m is set to the preset second correction coefficient m2, and the corrected wind pressure value A0 = m2 * Ai.
[0110] Specifically, the wind pressure unit also includes:
[0111] The early warning module is used to acquire data on the flatness of the steel wires in the finished fabric layer.
[0112] When the flatness data e of the finished fabric layer steel wire is greater than the preset third finished fabric layer steel wire flatness E3, an early warning command is generated.
[0113] Specifically, the air pressure value for the next tire's ply wire laying is set based on the flatness data of the finished ply wire. When the flatness of the finished ply wire is low, the air pressure value in the next production process is increased in time to ensure that the tension of the wires in the ply is consistent during the laying process of the next ply wire, control the tension fluctuation of a single wire during calendering, minimize the tension difference between each wire, and ensure that the ply surface wires are flat.
[0114] Specifically, when the flatness of the steel wires in the finished fabric layer exceeds the preset value, the early warning module promptly sends an early warning command, determines that the fabric layer is unqualified, and eliminates the unqualified products to ensure product quality.
[0115] According to the first concept of this application, by adding an air pressure unit, the air pressure value and the rate of change of air pressure are adjusted in real time according to the angular velocity of the spindle, so as to ensure that the wire tension and the difference in wire tension are within the standard range, effectively avoiding the problem of large differences in wire tension, improving product quality, improving the flatness of the fabric surface, and reducing the risk of sparse wires in the fabric.
[0116] According to the second concept of this application, by adding a monitoring unit and selecting an ultrasonic winding measurement system, the real-time wire tension and flatness data of the fabric layer during production are monitored. The air pressure unit adjusts the air pressure in real time based on the monitoring unit. This ensures consistent wire tension in the fabric, controls the fluctuation of individual wire tension during calendering, minimizes the tension difference between each wire, and ensures flatness of the fabric surface.
[0117] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
