[0063] During the production of rubber, the raw materials often include solid raw materials and liquid raw materials, and the solid raw materials and liquid raw materials are fed separately.

[0094] The liquid material mixing device is located in the fifth area. The liquid material mixing device includes a second premixing tank 9 and an independent storage tank 10. The second premixing tank 9 is used to premix liquid materials of different densities and viscosities into uniform premixed liquid materials. At the same time, it plays the role of premixed liquid material storage and accurately controls the liquid material feeding. The second premixing tank 9 is provided with a weighing component, and adopts the weight loss method for feeding. The accuracy error can be controlled within 2‰. This method of automated feeding is conducive to preserving the uniform repeatability of multiple batches of production and avoiding production errors caused by manual labor during the production process. The independent storage tank 10 can directly put liquid materials into the stirring device 8 and can be equipped with an integrated electronic scale.

[0095] The stirring device 8 is located in the sixth area. The stirring device 8 is used to mix the premixed powder fed from the fourth area according to the formula and the premixed liquid fed from the fifth area. The stirring device 8 adopts a high-power stirring and mixing device. Different types of equipment can be selected according to different production formulas, including but not limited to double planetary mixers, kneading machines, etc. The stirring device 8 can be equipped with a variety of auxiliary devices such as vacuuming, heating, cooling, etc.

[0096] The filling device is located in the seventh area. The filling device uses a high-pressure press device 16 to press the production rubber material into a filling machine 17, and the filling machine 17 performs packaging.

[0097] The glue production equipment can produce epoxy resin glue, epoxy putty, organic silica gel and polyurethane glue containing powder reinforcement phase.

[0098] After research, it was found that the relevant rubber production equipment has some shortcomings in the process of automated rubber production. For example, the production efficiency of rubber production equipment needs to be further improved, the connection and coordination between the equipment are not smooth, resulting in bottlenecks in the production process; the raw material filling is inaccurate, affecting the stability of product quality.

[0099] In view of this, an embodiment of the present application provides a control method for a rubber production equipment, which can stabilize the quality of the produced rubber while improving the production efficiency of the rubber production equipment.

[0100] The rubber production equipment of the embodiment of the present application includes a powder mixing device, a liquid material mixing device and a rubber mixing reaction device, and the powder mixing device and the liquid material mixing device are respectively connected to the rubber mixing reaction device.

[0101] Figure 3 A flow chart of a control method for a rubber production device provided in an embodiment of the present application is shown.

[0102] See also Figure 3 , the control method includes steps 100 to 400.

[0103] Step 100, obtaining first index data of the mixed powder in the powder mixing device and second index data of the liquid material in the liquid material mixing device; wherein the first index data includes one or more of the particle size, water content, fluidity parameter, loose density and first temperature of the mixed powder inside the powder mixing device; and the second index data includes one or more of the first density and first viscosity of the liquid material inside the liquid material mixing device.

[0104] In this step, the particle size of the mixed powder can be detected by using instruments such as a laser particle size analyzer and a sedimentation particle size analyzer installed in the powder mixing device, which is conducive to mixing the mixed powder evenly and meeting the standard mixing state requirements.

[0105] The moisture content of the mixed powder in the powder mixing device can be detected by microwave method, infrared method and capacitance method. For example, an online microwave moisture measurement and control instrument can be used and set in the powder mixing device to realize the detection. The sensor of the online microwave moisture measurement and control instrument transmits microwave signals and collects moisture information of the measured object. The host part is composed of an intelligent small computer and a control part, which can process the collected signals and display the moisture value on the display screen. It can also be connected to external devices through 4-20mA current signal or RS485 output to realize remote monitoring and other functions. It is suitable for installation on pipelines or tanks to fully contact with powders for measurement.

[0106] The fluidity parameters of the mixed powder in the powder mixing device can be detected by rheometer, Hall rheometer, etc. The Hall rheometer, rotational rheometer, etc. can be installed near the pipeline or the discharge port of the powder mixing device to measure its fluidity parameters in real time.

[0107] The bulk density of the mixed powder in the powder mixing device is measured by a capacitive density sensor, ultrasonic density meter, etc. The capacitive density sensor is based on the relationship between the dielectric constant and density of the powder. When the density of the powder changes, its dielectric constant will also change, resulting in a change in the capacitance value of the sensor. By calibrating the capacitance-density relationship of powders of different densities in advance, the bulk density of the powder can be inferred based on the capacitance value measured in real time. In the powder, the change in bulk density will affect the propagation characteristics of ultrasonic waves. By emitting ultrasonic waves in the powder and measuring parameters such as the propagation speed of ultrasonic waves and the intensity of reflected waves, the bulk density of the powder can be calculated using relevant physical models.

[0108] The temperature in the powder mixing device or the temperature of the mixed powder can be detected by a thermometer, such as a platinum resistance thermometer, an infrared thermometer, a thermocouple thermometer, a thermal resistance thermometer, etc.

[0109] The density and viscosity of the liquid in the liquid mixing device can be detected by using a density meter and a viscometer, respectively. For example, the probe of the rotational viscometer can be installed in the pipe or container of the liquid mixing device, so that the rotor is immersed in the liquid.

[0110] In this step, by detecting the first index data of the mixed powder in the powder mixing device and the second index data of the liquid material in the liquid material mixing device, the state and quality of the mixed powder and liquid material can be determined, which is convenient for the subsequent production of rubber.

[0111] Premixing a plurality of powder raw materials and a plurality of liquid raw materials to obtain mixed powder and liquid materials is beneficial to improving the efficiency of rubber production and to controlling the quality of the target rubber.

[0112] Step 200, when the first index data and the second index data meet the first preset condition, the mixed powder and liquid material are transported to the rubber mixing reaction device at the first conveying rate and the second conveying rate in sequence.

[0113] In this step, by judging the first index data of the mixed powder in the powder mixing device and the second index data of the liquid material in the liquid material mixing device, when their respective parameters meet the first preset conditions, it can be judged whether they are mixed evenly, and whether their respective dispersion states and qualities meet the standards, which is beneficial to the quality stability of the target rubber material.

[0114] The first conveying rate of the mixed powder and the second conveying rate of the liquid material can be determined according to the required quality and quality requirements of the target rubber material, such as solid content.

[0115] Step 300, detecting third index data of the rubber in the rubber mixing reaction device at a preset time; wherein the third index data includes one or more of a second density, a second viscosity, a mass and a solid content.

[0116] In this step, the second density of the rubber can be detected by installing a float type density meter, a vibration type density meter, a nuclear density meter and an online vibration type density meter in the rubber mixing reaction device. The viscosity and quality of the rubber can be detected by installing a viscometer and a weighing device. The solid content of the rubber can be detected by a solid content detector, such as the CSY-G3 rubber paint solid content detector of Shenfen Instruments, the Mettler Toledo Excellence Series Rapid Moisture Analyzer, etc.

[0117] Step 400, when the third indicator data meets the second preset condition, the target rubber material is produced.

[0118] In this step, the rubber mixing reaction device mixes the mixed powder and liquid material under certain conditions and makes them react to achieve the purpose of producing rubber. As the production process progresses, in order to take into account both production efficiency and rubber quality, when the rubber production meets the standards, it can enter the next packaging or filling process.

[0119] According to the method of the embodiment of the present application, the quality of the initial raw materials is judged by controlling the parameters of the powder mixture and the liquid mixture so as to quickly mix the powder mixture and the liquid mixture; the quality of the rubber is ensured while the rubber is quickly prepared.

[0120] In some optional embodiments, before step 100, that is, when the first indicator data and the second indicator data meet the first preset condition, before transporting the mixed powder and the liquid material to the rubber mixing reaction device at the first conveying rate and the second conveying rate in sequence, the method further includes:

[0121] The first preset condition is determined according to the fourth parameter value of the target rubber material and the historical production data of the target rubber material.

[0122] According to the product characteristics of the target rubber, the quality and characteristics of the raw materials for producing the target rubber can be determined respectively, and the raw materials are the mixed powder and liquid materials in the embodiment of the present application. Therefore, according to the fourth parameter value of the target rubber and the raw material characteristics in the historical production data of the target rubber, the raw material characteristics of the mixed powder and liquid materials in the embodiment of the present application are determined, which is conducive to accelerating production efficiency, reducing the situation of substandard rubber quality or low production efficiency such as uneven rubber density or too long stirring time in the rubber mixing reaction device, and can flexibly adapt to various production needs, especially suitable for the situation where one or more liquid raw materials are not suitable for direct premixing with a single powder.

[0123] In some optional embodiments, before step 100, the method further includes:

[0124] According to the first index data of the mixed powder and the third index data of the target slurry, the types of a plurality of powder raw materials, the corresponding masses and the corresponding particle sizes of the powder raw materials are obtained.

[0125] In some optional embodiments, before step 100, the method further includes:

[0126] According to the second index data of the liquid material and the third index data of the target slurry, the types of the plurality of liquid raw materials, the corresponding masses, and the corresponding densities and viscosities of the liquid raw materials are obtained.

[0127] In some optional embodiments, before step 200, the method further includes:

[0128] Step 110: determining a first conveying rate according to first indicator data of the mixed powder, first quality of the mixed powder and historical production data.

[0129] In some optional embodiments, before step 200, the method further includes:

[0130] Step 120, determining a second delivery rate according to the second indicator data of the liquid material, the quality of the second liquid material and historical production data.

[0131] The order of step 110 and step 120 can be arbitrary. The first indicator data of the mixed powder often reflects its key physical or chemical properties, such as particle size, loose density, etc. Different first indicator data correspond to different optimal first conveying rates. The second indicator data of the liquid material often reflects its key physical or chemical properties, such as viscosity, density, etc. Different second indicator data correspond to different optimal conveying rates. By accurately matching the first conveying rate with the first indicator data and matching the second conveying rate with the second indicator data, and using the above-mentioned historical production data to correct the first conveying rate and the second conveying rate respectively, the uniformity and consistency of the liquid material and the mixed powder in the rubber production process can be ensured, thereby improving the stability of product quality.

[0132] In some optional embodiments, in step 200, the first preset condition also includes that the mass of the mixed powder in the powder material mixing device is a first preset mass; and the mass of the liquid material in the liquid material mixing device is a second preset mass.

[0133] When the two raw materials, powder and liquid, have reached the predetermined quality, they will be transferred to the rubber mixing reaction device to avoid unstable quality caused by insufficient raw materials, ensure the continuity of raw material transportation, and improve production rate.

[0134] In some optional embodiments, after step 300, the method further includes:

[0135] Step 510, detecting a first real-time operating parameter of the rubber material mixing reaction device;

[0136] Step 520, under the condition that the first real-time operating parameter satisfies the first preset operating parameter, returns the third indicator data of the rubber in the rubber mixing reaction device at a preset time; the first preset operating parameter includes one or more of the pressure in the rubber mixing reaction device, the stirring speed of the stirring element in the rubber mixing reaction device, the dispersing speed of the dispersing element in the rubber mixing reaction device, the operating temperature in the rubber mixing reaction device and the operating time.

[0137] In the rubber mixing reaction device, it is detected in real time whether the first real-time operating parameter of the rubber mixing reaction device matches the preset first preset operating parameter. For example, the target rubber is epoxy glue or curing rubber, and the first preset operating parameter includes: the pressure is -120 to -90Kpa; optionally -95Kpa. The operating temperature is 0 to 50°C. The stirring rate includes 10-20 rpm in the first stage and 25 to 35 rpm in the second stage, and 30 rpm is optional. The dispersion rate includes 450-550 rpm in the first stage, and 500 rpm is optional; and 1800 to 2200 rpm in the second stage, and 2000 rpm is optional. The curing rubber may include one or more of polyethylene polyamine, polyether amine, phenolic amine and polyamide.

[0138] When the first real-time operating parameter matches the preset first preset operating parameter, the third indicator data of the material at the preset time is detected in real time to monitor the production of the rubber material. When the product meets the standard, it enters the next process, which can effectively ensure the production quality and improve the production efficiency.

[0139] In some optional embodiments, after step 300, the third indicator data includes the first current indicator data, and the method includes:

[0140] Step 610, obtaining first current index data of the rubber in the rubber mixing reaction device at a first moment;

[0141] Step 620, when the first current indicator data continuously exceeds the first rubber preset value within the preset time period, obtaining the first real-time conveying rate and the second real-time conveying rate and the second real-time operating parameter of the rubber mixing reaction device;

[0142] In this step, when the first current index data of the rubber material continuously exceeds the first preset value of the rubber material, the production of the surface rubber material is abnormal and needs to be processed. By detecting the first real-time conveying rate and the second real-time conveying rate and the second real-time operation parameter, the abnormal problem can be found so as to perform subsequent operations, realize automatic monitoring and automatic error correction, and avoid the problem of unstable rubber material quality caused by untimely human monitoring and detection.

[0143] Step 630, when one or more of the first real-time conveying rate, the second real-time conveying rate and the second real-time operating parameter are different from the corresponding first conveying rate, the second conveying rate and the first preset operating parameter, a correction alarm is issued and / or the corresponding operating parameters are adjusted until the first current indicator data meets the first rubber preset value.

[0144] In this step, when the operating parameters of the rubber mixing reaction device are normal, the first real-time delivery rate, the second real-time delivery rate and the second real-time operating parameter can be automatically detected to eliminate obstacles in the actual device or pipeline. The corresponding operating parameters can be adjusted according to the first delivery rate, the second delivery rate and the first preset operating parameter until the first current index data meets the first rubber preset value. That is, according to the preset first delivery rate, the second delivery rate and the first preset operating parameter, the deviation of the real-time operating parameter can be calibrated so that the first current index data meets the first rubber preset value and the quality of the rubber meets the standard.

[0145] According to the embodiment of the present application, the first real-time conveying rate, the second real-time conveying rate and the second real-time operating parameter can be automatically detected based on the first current indicator data of the rubber material at the first moment, and automatic calibration can be achieved or a correction alarm can be issued to ensure that the quality of the rubber material meets the standards.

[0146] In some optional embodiments, after step 300, the third indicator data includes the second current indicator data, and the method includes:

[0147] Step 710, detecting second current index data of the rubber in the rubber mixing reaction device at a second moment, the second current index data including a second density and / or a solid content;

[0148] Step 720: if the second density or solid content is less than the preset value of the second rubber material, a third real-time delivery rate of the mixed powder at different positions of the transmission pipeline and a fourth real-time delivery rate of the liquid material at different positions of the transmission pipeline are detected, and if the third real-time delivery rate and the fourth real-time delivery rate do not match the first delivery rate and the second delivery rate, a first alarm is issued and / or the actual delivery rate of the mixed powder and the liquid material is adjusted;

[0149] Step 730: If the third real-time delivery rate and the fourth real-time delivery rate match the first delivery rate and the second delivery rate, a second alarm is issued and / or a third real-time operating parameter of the rubber in the rubber mixing reaction device is detected.

[0150] According to the embodiment of the present application, when detecting the second current indicator data of the rubber material, the second density or solid content is respectively less than the second preset value of the rubber material, the third real-time conveying rate and the fourth real-time conveying rate can be detected to determine their matching with the preset first conveying rate and the second conveying rate, thereby issuing an alarm or automatically adjusting, and finding where the abnormal problem occurs so as to facilitate subsequent operations, realize automatic monitoring and automatic error correction, and avoid the problem of unstable rubber quality caused by untimely human monitoring and detection.

[0151] In some optional embodiments, after step 700, that is, after detecting the third real-time operating parameter of the rubber in the rubber mixing reaction device, the third real-time operating parameter includes one or more of an operating temperature, a stirring rate, a dispersion rate, or a pressure of the rubber in the rubber mixing reaction device; the method further includes:

[0152] Step 810: If the third real-time operating parameter matches the first preset operating parameter, one or more of the following operations are performed: increasing the operating temperature, stirring rate, dispersion rate, or reducing the pressure.

[0153] According to the embodiment of the present application, when the third real-time delivery rate and the fourth real-time delivery rate match the first delivery rate and the second delivery rate, any one or more of the operating parameters of the rubber mixing reaction device can be appropriately increased, the second density or solid content can be automatically adjusted, and automatic monitoring and automatic error correction can be achieved to avoid the problem of unstable rubber quality caused by untimely human monitoring and detection. For example, if real-time detection is not performed, some raw materials will agglomerate or stick together, which will make it difficult to achieve timely adjustment in subsequent processes, and even affect the quality stability of the rubber.

[0154] For example, the respective rates and degrees of increasing the operating temperature, stirring rate, dispersion rate or reducing the pressure can be determined based on historical production data or manually preset.

[0155] In some optional embodiments, after step 700, that is, after detecting the third real-time operating parameter of the rubber in the rubber mixing reaction device, the method further includes:

[0156] Step 820: If the third real-time operating parameter does not match the first preset operating parameter, a third alarm is issued and / or the first index data of the mixed powder in the powder mixing device and the second index data of the liquid material in the liquid mixing device are obtained.

[0157] According to an embodiment of the present application, if the third real-time operating parameter does not match the first preset operating parameter, a third alarm is issued for adjustment, or the control method is returned to the initial position for re-calibration.

[0158] In some optional embodiments, after step 300, the method further includes:

[0159] Step 910, recording multiple production times of multiple batches of target rubber produced by the rubber mixing reaction device;

[0160] Step 920, obtaining an average value of the production time according to the multiple production times;

[0161] Step 930, determining the preset production time according to the average value of the production time and the historical production data;

[0162] Step 940: If any one of the production times is greater than a preset time, the powder material in the powder material mixing device is emptied and / or the liquid material in the liquid material mixing device is emptied.

[0163] According to the embodiments of the present application, after the rubber production equipment has been running for a period of time, raw materials may agglomerate and become unevenly distributed in some areas of the powder material mixing device or the liquid material mixing device, which may also affect the production time of the rubber mixing reaction device. Therefore, emptying the powder in the powder material mixing device and / or emptying the liquid in the liquid material mixing device can improve production efficiency while achieving stable production of rubber under good quality conditions.

[0164] In some optional embodiments, the preset production time is determined according to the average value of the production time and historical production data, including: steps 931 to 933.

[0165] Step 931, the difference between the average value of the production time and the average value of the production time in the historical production data is a≤30min, and the production preset time is the average value.

[0166] Step 932, the difference a between the average value of the production time and the average value of the production time in the historical production data is 30 minutes to 1.5 hours, and the production preset time is the sum of 1 / 2a and the average value.

[0167] Step 933, the difference a between the average value of the production time and the average value of the production time in the historical production data is greater than 1.5h, and the production preset time is the average value.

[0168] According to the embodiments of the present application, the cycle for emptying the powder in the powder mixing device and / or emptying the liquid in the liquid mixing device can be determined according to the above method, which can improve production efficiency while achieving stable production of rubber under good quality conditions.
