Description

Technical Field

[0001] The present invention relates to the technical field of tire production, and more particularly, to a control method, a control device, and a storage medium for a tire production device. Background Art

[0002] During the tire production process, the extrusion process is one of the key links, involving the manufacture of semi-finished products such as treads, sidewalls, and filler rubbers. To improve the adhesion within a certain area of the tire, it is often necessary to online bond a film or other semi-components with a certain width and thickness to the extruded semi-finished product, which is usually achieved through the linkage line of an external extruder and a calender.

[0003] Therefore, when using an external extruder to link with a calender for online continuous production and bonding, the matching of the rotational speeds of the extruder and the calender is crucial. In traditional operations, the matching of the rotational speeds of the extruder and the calender often relies on the experience of operators and manual adjustment, lacking an accurate control method. This manual adjustment method has the following problems:

[0004] 1. Excessive accumulated rubber: If the rotational speed of the extruder is higher than that of the calender, there will be a situation of excessive rubber material, which will cause the accumulation of rubber material on the calender, and the temperature of the rubber material far from the surface of the calender roller will decrease, resulting in quality problems such as rubber scars and holes during the calendering process.

[0005] 2. Risk of lack of rubber: On the contrary, if the rotational speed of the extruder is lower than that of the calender, it may lead to insufficient rubber material supply, causing a lack of rubber on the calender, and further resulting in a smaller width of the component and a broken film, seriously affecting production efficiency and product quality.

[0006] 3. Unstable production: Due to the lack of an accurate control method, the matching between the extruder and the calender is often unstable, resulting in fluctuations in the bonding quality of the film or other semi-components, affecting the performance and appearance of the tire.

[0053] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0054] As mentioned in the background art, when extruding semi-finished products such as the tread 400, the sidewall 500, and the filler 600, a film or other semi-component (such as a film having a certain width and thickness) is attached to increase the viscosity in a certain area. Figure 3 ), this component is generally produced and bonded online continuously using an external extruder linked to a calender. The matching of the extruder speed and the calender speed is crucial. If the extruder speed is faster than the calender speed, it will cause excessive glue accumulation on the calender, and the temperature of the rubber away from the surface of the calender roller will become lower, which will cause glue scars and holes during calendering. If the extruder speed is slower than the calender speed, it will cause glue shortage on the calender, and the width of the component will become smaller during calendering, and the rubber will break, which will ultimately affect the production quality of the tire. Therefore, in response to the above technical problems, the present application provides a control method for a tire production device, which obtains the cross-sectional area S of the half component to be bonded. 半部件 As well as the operating parameters of the calender, the weight M of the rubber material supplied by the calender per unit time t is obtained. 出压延机 , and then the running linear speed v of the conveyor belt is obtained 运输带 ; Further, obtain the glue discharge amount Q of the extruder 100 挤出机and the weight M of the rubber compound extruded by the extruder 100 per unit time t 出挤出机 ; Since it is necessary to ensure that the weight of the rubber compound extruded by the extruder 100 per unit time t is the same as the weight of the rubber compound received by the calender per unit time t, and the weight M of the rubber compound supplied by the calender 300 per unit time t 出压延机 is the same as the weight M of the rubber compound received 进压延机 is the same, therefore, based on the discharge amount Q of the extruder 100 挤出机 and the weight M of the rubber compound extruded by the extruder 100 per unit time t 出挤出机 , the operating speed N of the extruder 100 can be obtained 挤出机 ; And control the extruder 100 to operate at the speed N 挤出机 , and the conveyor belt operates at the linear speed v 运输带 . At the same time, since the operating linear speed v of the calender 300 压延机 needs to be the same as the linear speed v of the main conveyor line 主线 , the rotational speed ω of the calender can be obtained 压延机 . In this way, it can be ensured that in the actual production process, the production rhythms among the calender 300, the main conveyor line, the extruder 100, and the conveyor belt 200 are matched, enabling the calender 300 to continuously and stably provide the laminated semi-components, which are mutually matched with the amount of rubber compound extruded by the extruder 100, and avoiding the risks of excessive or insufficient rubber accumulation in the calender 300.

[0055] Please refer to Figure 1 and Figure 2 , this application provides a control method for a tire production device. The tire production device includes an extruder 100, a calender 300, and a main conveyor line. The discharge end of the calender 300 is docked with the main conveyor line, and the feeding ends of the extruder 100 and the calender 300 are connected by a conveyor belt 200. The control method includes:

[0056] Obtain the cross-sectional area S of the semi-component to be laminated 半部件 ;

[0057] Based on the cross-sectional area S of the semi-component to be laminated 半部件 and the operating parameters of the calender 300, obtain the weight M of the rubber compound supplied by the calender 300 per unit time t 出压延机 , and the operating parameters of the calender 300 at least include: the linear speed of the calender 300: v 压延机 ;

[0058] Among them, the linear speed v of the calender 300 压延机 is the same as the linear speed v of the main conveyor line 主线 ;

[0059] Based on the linear speed v of the calender 压延机 , obtain the rotational speed ω of the calender压延机 ;

[0060] Control the calender to run at a rotational speed ω 压延机 ;

[0061] According to the weight M of the rubber compound supplied by the calender 300 within the unit time t 出压延机 being the same as the weight M of the rubber compound received, obtain the running linear speed v of the conveyor belt 进压延机 ; 运输带 ;

[0062] Control the conveyor belt to run at the linear speed v 运输带 ;

[0063] Obtain the rubber output Q of the extruder 100 挤出机 and the weight M of the rubber compound extruded by the extruder 100 within the unit time t 出挤出机 ;

[0064] The weight M of the rubber compound extruded by the extruder 100 within the unit time t 出挤出机 is the same as the weight M of the rubber compound received by the calender 300 within the unit time t 进压延机 ;

[0065] According to the rubber output Q of the extruder 100 挤出机 and the weight M of the rubber compound extruded by the extruder 100 within the unit time t 出挤出机 , obtain the running rotational speed N of the extruder 100 挤出机 ;

[0066] Control the extruder 100 to run at the rotational speed N 挤出机 ;

[0067] According to the control method of the tire production device provided by the present application, based on the "law of conservation of mass" of the rubber compound, that is, the weight of the rubber compound extruded by the extruder 100 within the unit time is equal to the weight of the rubber compound entering the calender 300 within the unit time and is equal to the weight of the rubber compound supplied to the main extrusion production line after calendering by the calender 300, the linear speed v of the conveyor belt 200 can be obtained through calculation 运输带 and the running rotational speed N of the extruder 100 挤出机 , by controlling the conveyor belt 200 to run at the linear speed v 运输带 , controlling the extruder 100 to run at the rotational speed N 挤出机 , and at the same time, by making the linear speed v of the main conveyor line 主线 the same as the linear speed v of the calender 300 压延机 , obtain that the calender needs to run at the rotational speed ω 压延机Running can ensure the precise matching of process parameters among the extruder 100, conveyor belt 200, calender 300 and the main conveyor line, thus realizing the continuous and stable supply and laminating process of the rubber compound, effectively avoiding the phenomena of rubber accumulation or lack of rubber caused by mismatched equipment speeds, and improving production efficiency and product quality.

[0068] The control method establishes the mathematical model relationship among various equipment based on the "law of conservation of mass", can reasonably plan and utilize the rubber compound resources, avoid excessive or insufficient material supply, helps to save raw material costs, and at the same time reduces the scrap rate. Whether in the production process of different types of films or semi-components (such as tread, sidewall, filler rubber), or facing different production demand changes, this control method can flexibly adjust relevant parameters, quickly adapt to the new production environment, and enhance production flexibility and reliability.

[0069] In the specific implementation process, the method for obtaining the weight M of the rubber compound supplied by the calender 300 within the unit time t 出压延机 includes:

[0070] M 出压延机 = S 半部件 × ρ 胶料 × v 压延机 × t;

[0071] where ρ 胶料 is the density of the rubber compound, and the linear speed v of the calender 压延机 is the same as the linear speed v 主线 of the main conveyor line.

[0072] During the production process, directly obtain the density ρ 胶料 of the rubber compound and the cross-sectional area S 半部件 of the semi-component to be produced. Among them, the running linear speed v 压延机 of the calender 300 is stored in the data processing module. The density of the rubber compound is determined by the type of the rubber compound and can be directly selected in the control system. Just input the cross-sectional area S 半部件 of the semi-component to be produced into the data processing module, and the weight M of the rubber compound supplied by the calender 300 within the unit time t can be obtained according to the above calculation formula 出压延机 .

[0073] When the production conditions change, such as replacing the rubber compound with different densities or adjusting the speed of the calender 300, the required rubber compound supply amount of the calender 300 can be quickly calculated using the above formula, and then the operating parameters of the calender 300 can be adjusted immediately to maintain the stability and high efficiency of the production line. Managing the supply and consumption of the rubber compound in an over-quantified manner ensures the material balance in the production process, avoids production stagnation or waste caused by insufficient or excessive rubber compound supply amount, and improves the accuracy of the production plan and the efficiency of material management.

[0074] Furthermore, obtain the rotational speed ω of the calender 压延机 The method includes:

[0075]

[0076] where d 辊筒 is the roll diameter of the calender.

[0077] where the linear velocity v of the main conveyor line 主线 can be obtained by a tachometer or photoelectric speed measurement. Based on the linear velocity v of the main conveyor line 主线 adjust the rotational speed ω of the calender 300 压延机 , the running linear velocity v of the conveyor belt 200 运输带 , and the running rotational speed N of the extruder 100 挤出机 so that the semi-components extruded by the calender 300 can be accurately attached to the tread or sidewall of the tire on the main conveyor line or semi-finished products such as filler rubber.

[0078] In this application, the method for obtaining the running linear velocity v of the conveyor belt 运输带 includes:

[0079]

[0080] where S 胶条 is the cross-sectional area of the rubber strip extruded by the extruder 100.

[0081] Since the extruder 100 is connected to the calender 300 through the conveyor belt, the rubber strip extruded by the extruder 100 is transported to the calender 300 through the conveyor belt, so that the weight M of the rubber material received by the calender 300 within the unit time t 进压延机 is the same as the weight of the rubber material extruded by the extruder 100. Therefore, based on the weight M of the rubber material received by the calender 300 within the unit time t 进压延机 and the cross-sectional area S of the rubber strip extruded by the extruder 100 胶条 , the running linear velocity v of the conveyor belt can be calculated 运输带 to ensure that the transmission rate of the rubber material matches the demand rate of the calender 300.

[0082] Furthermore, the method for obtaining the weight M of the rubber material received by the calender 300 within the unit time t 进压延机 includes:

[0083] M <00> 进压延机 = M 出压延机 = S 半部件 × ρ 胶料 × ω 压延机 × d 辊筒 × t;

[0084] Among them, ω 压延机 is the roller speed of the calender;

[0085] d 辊筒 is the roller diameter of the calender.

[0086] Calculating that the weight of the rubber compound received by the calender 300 is equal to the extruded weight realizes the precise balance of materials during the calendering process, avoids the problems of excessive or insufficient rubber compound, and ensures the continuity and stability of the production main line. Through the quantitative calculation of the roller speed and diameter of the calender 300, a more refined parameter adjustment method than traditional control is provided, which is conducive to achieving high-precision quality control. Ensuring that the calender 300 can continuously and stably receive the rubber compound reduces the number of starts and stops of the production line, improves production efficiency and the throughput of the production line. When changing the product type or adjusting the production scale, only the corresponding geometric dimension and rubber compound density parameters need to be input, and the receiving amount of the calender 300 can be quickly adjusted, simplifying the process adjustment process and improving production flexibility.

[0087] In the specific implementation process, the method for obtaining the operating speed N 挤出机 of the extruder 100 includes:

[0088]

[0089] Since the rubber discharge amount Q 挤出机 is the fixed production capacity of the extruder 100 and is independent of the speed and operating time of the extruder 100 under the condition that the feeding width, thickness are stable and the motor power is satisfied, therefore, taking the rubber discharge amount Q 挤出机 of the extruder 100 as a fixed quantity, the operating speed N 挤出机 of the extruder 100 can be obtained through calculation.

[0090] Dynamically adjusting the speed of the extruder 100 according to production requirements ensures that the output rubber compound amount is neither excessive nor insufficient, realizes a high degree of matching between material supply and demand, and ensures the smooth operation of the production process. Accurately controlling the speed of the extruder 100 reduces the time for production line pauses and readjustments caused by insufficient or excessive rubber compound supply, improves production efficiency, and shortens the product delivery cycle. Precise control of materials reduces rubber compound waste and reuse, reduces production costs, and also reduces additional energy consumption and equipment wear caused by material imbalance.

[0091] Furthermore, the method for obtaining the weight M 出挤出机 of the rubber compound extruded by the extruder 100 per unit time t includes:

[0092] M 出挤出机 = M 出压延机 = S 半部件 × ρ 胶料 × ω压延机 ×d 辊筒 ×t.

[0093] The above method directly establishes the mathematical relationship between the output of the extruder 100 and the demand of the calender 300, ensuring the precise control of the material flow, avoiding the problems of over-supply or under-supply, and improving the material management efficiency of the entire production process. By precisely matching the working parameters between the extruder 100 and the calender 300, the linkage mechanism between the two is optimized, reducing the production stagnation caused by equipment mismatch and enhancing the stability and continuity of the production line.

[0094] In specific implementation, the method for obtaining the glue output Q of the extruder 100 挤出机 includes:

[0095] Controlling the extruder 100 to run at the initial speed N 初始 for a unit time t;

[0096] Obtaining the mass M of the glue extruded by the extruder 100 within the unit time t;

[0097]

[0098] Among them, the glue output Q 挤出机 represents the inherent production capacity of the equipment, and is independent of the speed and running time of the extruder 100 when the feeding width, thickness are stable and the motor power is satisfied.

[0099] The core of the speed matching between the extruder 100 and the calender 300 is the "law of conservation of mass" of the glue, that is, the weight of the glue extruded by the extruder 100 per unit time is equal to the weight of the glue entering the calender 300 per unit time, which is equal to the weight of the glue supplied to the main extrusion production line after being calendered by the calender 300. Therefore, the measurement of the glue output Q of the extruder 100 should be carried out first:

[0100] Start the extruder 100 to run at the speed of N for the unit time t, and measure the mass of the extruded glue within the unit time t as M. Then calculate the glue output Q as:

[0101]

[0102] Q represents the glue output at the speed of N and within the unit time t respectively. The larger t is, the more accurate the measured glue output is.

[0103] Specifically, in the actual operation process, the following steps are used for calculation:

[0104] First, the relationship between the speed of the calender 300 and the speed of the main production line:

[0105] The linear speed of the pulling roll of the calender 300 should be consistent with the main line, that is:

[0106] v 压延机 = v 主线 = ω 压延机 × d 辊筒 ;

[0107]

[0108] where ω 压延机 represents the calender speed, d 辊筒 is the calender roll diameter. At this time, the weight of the rubber compound supplied by the calender 300 per unit time t to the extrusion production main line with a cross-sectional area of S 半部件 is M 出压延机 :

[0109] M 出压延机 = S 半部件 × ρ 胶料 × v 压延机 × t = S 半部件 × ρ 胶料 × ω 压延机 × d 辊筒 × t;

[0110] Secondly, the relationship between the linear speed of the rubber strip conveyor belt and the speed of the calender 300:

[0111] The cross-sectional area of the rubber strip of the extruder 100 is measured as S 胶条 , the linear speed of the conveyor belt is v 运输带 , the density of the rubber compound is ρ 胶料 , and the weight of the rubber compound entering the calender 300 per unit time by the conveyor belt is M 进压延机 , and the formula can be obtained:

[0112] M 进压延机 = S 胶条 × ρ 胶料 × v 运输带 × t

[0113] Also, due to the principle of conservation of rubber compound mass, the weight of the rubber compound entering the calender 300 per unit time t is equal to the weight of the rubber compound pressed out by the calender 300 per unit time t, that is:

[0114] M 进压延机 = M 出压延机 = S 胶条 × ρ 胶料 × v 运输带 × t = S 半部件 × ρ 胶料 × ω 压延机 × d 辊筒 × t

[0115]

[0116] Finally, the relationship between the rotational speed of the extruder 100 and that of the calender 300:

[0117] Due to the principle of conservation of rubber compound mass, the weight M of the rubber compound discharged by the extruder 100 at a rotational speed N within a unit time t 出挤出机 is equal to the weight M of the rubber compound entering the calender 300 within a unit time t 进压延机 is equal to the weight M of the rubber compound supplied to the main extrusion production line after being calendered by the calender 300 出压延机 , that is:

[0118] M 出挤出机 = Q 挤出机 × N 挤出机 × t;

[0119] = M 出压延机 = S 半部件 × ρ 胶料 × ω 压延机 × d 辊筒 × t;

[0120]

[0121] where Q is the rubber compound discharge amount of the extruder 100, obtained by measurement, and N is the rotational speed of the extruder 100.

[0122] Through this calculation, the relationship between the rotational speed of the calender and the linear speed, the relationship between the linear speed of the rubber strip conveyor belt and the rotational speed of the calender 300, and the relationship between the rotational speed of the extruder 100 and the rotational speed of the calender 300 can be established.

[0123] Measure the rubber compound discharge amount Q of the extruder 100 挤出机 , the roll diameter d of the calender 300 辊筒 , the cross-sectional area S of the rubber strip of the extruder 100 胶条 , the rubber compound density ρ 胶料 After that, the cross-sectional area of the semi-component to be laminated required for the main extrusion production line is S 半部件 Transferred to the PLC through MES construction, the main extrusion production line, the calender 300, the rubber strip conveyor belt 200, and the rotational speed of the extruder 100 can be linked and controlled, enabling the calender 300 to continuously and stably supply the semi-components for lamination, and avoiding the risk of excessive or insufficient rubber accumulation in the calender 300. Through the "law of conservation of mass" of the rubber compound, that is, the weight of the rubber compound extruded by the extruder within a unit time is equal to the weight of the rubber compound entering the calender 300 within a unit time, which is equal to the weight of the rubber compound supplied to the main extrusion production line after being calendered by the calender 300. Through this calculation, the relationship between the rotational speed of the calender 300 and the linear speed, the relationship between the linear speed of the rubber strip conveyor belt 200 and the rotational speed of the calender 300, and the relationship between the rotational speed of the extruder 100 and the rotational speed of the calender 300 are established.

[0124] Then, through the linkage between MES (Manufacturing Execution System) and PLC (Programmable Logic Controller), the four-way linkage control of the main extrusion production line, calender 300, rubber strip conveyor belt 200, and the rotation speed of extruder 100 is achieved (such as Figure 1 ).

[0125] This application also provides a control device, which is applicable to the control method of the tire production device in the above embodiment. The control device includes:

[0129] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0130] According to the control method of the tire production device provided by this application, based on the "law of conservation of mass" of the rubber compound, that is, the weight of the rubber compound extruded by extruder 100 per unit time is equal to the weight of the rubber compound entering calender 300 per unit time, which is equal to the weight of the rubber compound supplied to the main extrusion production line after being calendered by calender 300. The linear speed v 运输带 of conveyor belt 200 and the operating rotation speed N 挤出机 of extruder 100 can be obtained through calculation. By controlling conveyor belt 200 to run at the linear speed v 运输带 , controlling extruder 100 to run at the rotation speed N 挤出机 , and at the same time, by making the linear speed v 主线 of the main conveyor line the same as the linear speed v 压延机 of calender 300, it is obtained that the calender needs to run at the rotation speed ω 压延机The operation can ensure the precise matching of process parameters among the extruder 100, the conveyor belt 200, the calender 300 and the main conveyor line, thus realizing the continuous and stable supply and laminating process of the rubber compound, effectively avoiding the phenomena of accumulated rubber or lack of rubber caused by the mismatching of equipment speeds, and improving the production efficiency and product quality.
