Description

Technical Field

[0001] This invention relates to the field of rubber pretreatment technology, specifically to a stepped adjustable self-feedback system and its corresponding structural device. Background Technology

[0002] During the process of the extruder acting on the rubber compound, the rubber compound (raw rubber) is originally in a highly elastic state. The feeding mechanism transports the rubber compound into the barrel, and the screw shears, heats, and plasticizes the rubber compound. The heating system of the extruder barrel keeps it at a certain temperature, and as the screw rotates and propels it forward, it gradually transforms into a molten state. However, in production, there are problems such as poor thermoplasticization of the raw rubber compound by the extruder, which leads to quality problems in the extrusion of semi-finished parts, affecting the product conveying efficiency, stability, and process operation control of subsequent processes.

[0003] Current technologies directly process rubber compounds using extruders without any pretreatment device. This leads to issues such as poor thermoplasticization of the raw rubber sheets by the extruder, resulting in quality problems in the extruded parts and affecting product quality stability and subsequent process control. Furthermore, traditional adjustment methods for the pretreatment heating process lack tiered adjustment and cannot self-adjust and optimize feedback signals, especially in applications requiring precise control and rapid response. Therefore, there is an urgent need to design a tiered adjustable self-feedback system and its corresponding structural device. This system, through tiered adjustment and self-feedback mechanisms, can achieve more precise and faster control, making the pretreatment heating process of rubber compounds more intelligent, accurate, and safe, and optimizing the processing performance and smoothness of the extruder.

[0067] The working principle and beneficial effects of the above technical solution are as follows:

[0068] The present invention relates to a tiered adjustable self-feedback system comprising a temperature sensing unit, a target temperature setting unit, a tiered adjustment control unit, a heating / cooling execution unit, and a self-feedback adjustment module. These units and modules work synergistically to monitor the system's output signal in real time, compare it with the desired output, generate a feedback signal, and achieve system self-adjustment and optimization. The system can flexibly adjust the parameters of the tiered adjustment control unit and the self-feedback adjustment module according to different application scenarios and requirements to adapt to different control demands. Simultaneously, the tiered adjustment control unit, based on the setting of multiple adjustment levels, achieves fine adjustment of the input signal, improving the system's adjustment accuracy and response speed. Thus, it dynamically adjusts the adjustment strategy based on the feedback signal to achieve precise water temperature control and rapid response.

It is intelligent, accurate and safe, reduces labor, saves money and is highly efficient, and has a high degree of intelligence.

[0071] Example 2

[0072] Based on Example 1, such as Figures 2-4 As shown, a structural device is applied to the stepped adjustable self-feedback system according to any one of claims 1-4. The structural device includes a rubber pretreatment device, which includes: a mounting plate 1, which is fixedly installed in the middle of a frame 2; a feeding conveyor belt 3 is provided on the top of the frame 2; a circulating water temperature control mechanism 4 is provided on the top of the mounting plate 1; a heating roller 5 is fixedly installed on the top of the frame 2 by two fixing plates 6, and both ends of the heating roller 5 are rotatably connected to the fixing plates 6; a rotary joint 7 is fixedly connected to one side of the heating roller 5; a drive motor 8 is fixedly installed on the top of the fixing plates 6; a gear 9 is fixedly installed on the output shaft of the drive motor 8, and the gear 9 meshes with the rotary joint 7; and a first temperature detection probe 10 is fixedly installed on one side of the top of the frame 2.

[0073] Preferably, the circulating water temperature control mechanism 4 includes: a tank 11, which is fixedly installed on the top of the mounting plate 1; a heating pipe 12 installed inside the tank 11; a cooling water pipe 13 with its outlet connected to the cooling water inlet of the tank 11; a water pump 14 fixedly connected to the cooling water pipe 13; and an electromagnetic proportional valve 15 fixedly connected to the cooling water pipe 13 near the tank 11; and a second temperature detection probe 16 fixedly installed on the inner wall of the tank 11.

[0074] Preferably, it also includes an inlet pipe 17 and a return pipe, wherein the outlet of the tank 11 is connected to the inlet of the heating roller 5 through the inlet pipe 17, and the inlet of the tank 11 is connected to the outlet of the heating roller 5 through the return pipe 18.

[0075] The working principle and beneficial effects of the above technical solution are as follows:

[0076] The aforementioned rubber pretreatment device, through a second temperature detection probe 16, an electromagnetic proportional valve 15, a heating roller 5, and a drive motor 8, gears 9, and a circulating water temperature control mechanism 4 that drive the heating roller to rotate, completes the heating pretreatment of the rubber material. The rubber material runs along the feeding conveyor belt 3, realizing the feeding and transportation process. The circulating water temperature control mechanism 4 transports circulating heated water along the pipeline and delivers it to the heating roller 5. The heating roller 5 heats up and exchanges heat with the rubber material, thus realizing the heating pretreatment of the rubber material.

[0077] When the above-mentioned rubber pretreatment device performs heating pretreatment, the circulating water used for heating is powered by the water pump 14 and enters the tank 11 through the cooling water pipe 13. The rotary joint 7 at one end of the heating roller 5, together with the drive motor 8 and gear 9, enables the heating roller 5 to rotate along the fixed plate 6, thereby achieving heating pretreatment of the rubber. The return water pipe 18 is used to transport the circulating water in the heating roller 5 back to the tank 11. The heating pipe 12 installed inside the tank 11 can heat the circulating water in the tank 11 as needed. The cooling water pipe 13 is fixedly connected to the electromagnetic proportional valve 15 near the tank 11 to control the circulating water entering the tank 11. The second temperature detection probe 16 is fixedly installed on the inner wall of the tank 11 to facilitate the detection of the temperature of the rubber to be treated, and to facilitate feedback to the stepped adjustable self-feedback system, thereby accurately controlling the temperature of the rubber during heating pretreatment.

[0078] The aforementioned rubber pretreatment device operates under a stepped adjustable self-feedback system. First, the first temperature detection probe 10 detects the temperature of the rubber compound. This temperature is sent as input to the stepped adjustable self-feedback system to determine if it falls within the standard requirement range. If it is below the standard requirement range, the system then sends a signal to the inverter connected to the heating tube 12 within the circulating water temperature control mechanism 4. The inverter controller increases the power of the heating tube 12, heating the circulating water in the tank 11. The increased temperature of the circulating water enhances the heating effect of the heating roller 5, thereby raising the temperature of the rubber compound. The progressive increase in power of the heating tube 12 controlled by the stepped adjustable self-feedback system can be manually controlled. After a certain interval (the interval can be manually controlled, e.g., 3 minutes), once the temperature of the rubber compound (original sheet rubber) stabilizes, the first temperature detection probe 10... If the temperature of the rubber compound is still higher than the standard requirement range, the processing continues according to the above closed-loop logic. When the detected temperature is higher than the standard requirement range, the stepped adjustable self-feedback system transmits a signal to the cooling water electromagnetic proportional valve 15 controller of the circulating water temperature control mechanism 4. The opening of the electromagnetic proportional valve 15 increases, and at the same time, the water pump 14 receives the signal and starts working to provide power to the cooling water. The cooling water enters the tank 11, driving the temperature of the circulating cooling water down, thereby reducing the heating effect of the heating roller 5 and achieving the effect of lowering the temperature of the rubber compound. The step-adjustable self-feedback system controls the electromagnetic proportional valve 15 to adjust the opening degree each time, which can be manually controlled and set. Finally, after a certain interval, that is, after the temperature of the rubber compound (original sheet rubber) reaches stability (the interval control time can be manually controlled and set), the first temperature detection probe 10 detects the temperature of the rubber compound again. If it is still lower than the standard requirement range, the processing continues according to the above closed-loop logic.

[0079] The aforementioned rubber pretreatment device, in conjunction with a stepped adjustable self-feedback system, controls the temperature of the progressively circulating water, thereby controlling the heating effect of the heating roller 5 on the rubber compound. The stepped progressive control is controllable, realizing a progressively controlled process, and thus achieving a more precise preheating process for the rubber compound.

[0080] Example 3

[0081] The stepped adjustable self-feedback system described in Example 1 or 2 further includes a heating performance testing device for detecting the working state of the heating roller 5 during the pre-treatment of the rubber compound. The heating performance testing device includes:

[0082] A flow meter is used to detect the flow rate of the circulating water inside the heating roller 5;

[0083] A flow rate sensor is used to detect the flow rate of circulating water inside the heating roller 5 during operation in the rubber pretreatment unit;

[0084] Temperature sensor 1 is used to detect the ambient temperature when the rubber pretreatment unit is in operation.

[0085] Temperature sensor 2 is used to detect the temperature of the water inside heating roller 5;

[0086] The controller and the alarm are electrically connected to the flow meter, flow velocity sensor, temperature sensor one, temperature sensor two, second temperature detection probe 16 and the alarm. The controller controls the alarm to work based on the flow meter, flow velocity sensor, temperature sensor one, temperature sensor two and second temperature detection probe 16.

[0087] Preferably, the controller controls the alarm based on the flow meter, flow velocity sensor, temperature sensor one, temperature sensor two, and second temperature detection probe 16, including the following steps:

[0088] Based on the following formula and the detection values ​​from the flow meter, flow velocity sensor, temperature sensor one, temperature sensor two, and the second temperature detection probe 16, the actual heat exchange capacity of the heating roller 5 in the current rubber pretreatment device during the heating pretreatment of the rubber compound is calculated. The controller compares the actual heat exchange capacity of the heating roller 5 in the current rubber pretreatment device when pre-treating the rubber compound. If the actual heat exchange capacity falls below the preset range, the controller will activate the alarm.

[0089] ;

[0090] in, The actual heat exchange capacity (in units) of the heating roller 5 in the rubber pretreatment device when pretreating the rubber compound by heating (in units) ), This is the measured value of the flow rate of the circulating water inside the heating roller 5 by the flow meter. This is the value detected by the flow rate sensor of the circulating water velocity inside the heating roller 5 during the operation of the rubber pretreatment device. To adjust the density of the circulating water inside heating roller 5, The length of heating roller 5, The temperature sensor detects the ambient temperature during operation of the rubber pretreatment unit. The temperature sensor two measures the temperature of the water inside the heating roller 5. The convective heat transfer coefficient between the circulating water and the heating roller 5 (unit: K), The coefficient of convective heat transfer between the rubber compound and the heating roller 5. The thickness of heating roller 5, The thermal conductivity of the heating roller 5 itself (in units of...) K (obtained by looking up a table), The cross-sectional area of ​​the water inlet pipe 17 is... The length of the inlet pipe 17 The temperature reading of the water inside the tank 11 is measured by the second temperature detection probe 16. Let B be the convective heat transfer coefficient between the circulating water and the inlet pipe 17, and let B be the wall thickness of the inlet pipe 17. The thermal conductivity of the inlet pipe 17 itself (unit: K is obtained by looking up a table.

[0091] The beneficial effects of the above technical solution are as follows: First, based on the formula and the detection values ​​of the flow meter, flow velocity sensor, temperature sensor one, temperature sensor two, and the second temperature detection probe 16, the actual heat exchange capacity of the heating roller 5 in the current rubber pretreatment device is calculated when it heats and pretreats the rubber compound. This is achieved by comprehensively considering the flow rate of the circulating water inside the heating roller 5, the velocity of the circulating water inside the heating roller 5 during operation of the rubber pretreatment device, the density of the circulating water inside the heating roller 5, and the length of the water in the heating roller 5, all within the pretreatment process. The calculation results are more accurate and reliable by taking into account the ambient temperature during the operation of the treatment device, the temperature of the water inside the heating roller 5, the convective heat transfer coefficient between the circulating water and the heating roller 5, the convective heat transfer coefficient between the rubber material and the heating roller 5, the thickness of the heating roller 5, the thermal conductivity of the heating roller 5 itself, the cross-sectional area of ​​the water inlet pipe 17, the length of the water inlet pipe 17, the temperature of the water inside the tank 11, the convective heat transfer coefficient between the circulating water and the water inlet pipe 17, the wall thickness of the water inlet pipe 17, and the thermal conductivity of the pipe wall itself.

[0092] The controller controls the operation of the flow meter, flow velocity sensor, temperature sensor one, temperature sensor two, second temperature detection probe 16, and alarm. If the actual heat exchange capacity of the heating roller 5 in the current rubber pretreatment device is lower than the preset heat exchange capacity range during the pretreatment of the rubber compound, the controller activates the alarm to remind the staff to promptly inspect the interior of the heating roller 5 and perform maintenance on the interior of the heating roller 5 based on the actual inspection results. This ensures the heating roller 5 meets the usage requirements during pretreatment, guarantees the stable operation of the rubber pretreatment device during pretreatment, improves the working efficiency of the rubber pretreatment device, and effectively extends the service life of the heating roller 5. This further meets the requirements of the rubber pretreatment device for overall operational reliability and stability during pretreatment of the rubber compound. By monitoring the working status of the heating roller 5 in real time, the efficiency of the heating roller 5 in the pretreatment of the rubber compound is increased, and it is also ensured that the rubber pretreatment device can be quickly detected and repaired in a timely manner after a fault occurs.
