Description

Technical Field

[0001] This invention relates to the field of tire processing technology, specifically to a radial tire with a breathable fiber structure and its processing method. Background Technology

[0002] As the core component of a vehicle in contact with the ground, the performance of tires directly affects driving safety, comfort, and durability. Traditional tires often use a rubber matrix mixed with reinforcing fillers such as carbon black and silica for the tread and sidewall. During vehicle operation, the friction between the tread and the ground generates a large amount of heat, and the sidewall also generates heat due to internal friction during deformation.

[0003] Chinese patent CN114603817A discloses an extruder for tire rubber, including a support frame and equipment components mounted on the support frame. The equipment components are provided with a rubber extrusion box, and the feed end of the rubber extrusion box is provided with an input pipe. The equipment components are provided with a material pipe support for supporting the input pipe, and the input pipe is swingable and limited to the feed end of the rubber extrusion box.

[0004] In the prior art, since the rubber compound itself has the principle of thermal expansion and contraction, and the temperature of the rubber compound after being discharged from the extrusion nozzle is higher than the room temperature and needs to be cooled and contracted, if the temperature of the extruded rubber compound changes inside the gear pump, the amount of contraction produced after the rubber compound is cooled to room temperature after extrusion will also be different, which will result in the extruded rubber compound having cross-sectional dimensions that do not meet the requirements.

[0005] In actual use, the regulating device changes the size of the extrusion nozzle due to temperature changes, thereby adjusting the amount of rubber discharged from the nozzle. However, increasing the nozzle area will cause the gap to become larger, which will lead to air mixing into the extruded rubber and making the product unqualified. Conversely, decreasing the nozzle area will cause the gap to become smaller, which will lead to rubber accumulation at the gear pump nozzle and affect its own structure.

[0006] During the process of heating and conveying the rubber compound in the extruder, blockages can still occur inside the extruder and gear pump. However, relying solely on the temperature detection of the existing device cannot accurately determine the occurrence and location of the blockage, ultimately affecting the normal and continuous discharge of the subsequent rubber compound.

[0007] Meanwhile, the extruder or gear pump is also prone to structural damage during long-term use, which can affect the normal discharge of subsequent rubber materials. Existing technologies cannot quickly determine the location of the damage, thus increasing the difficulty of maintenance. Summary of the Invention

[0008] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a radial tire with a breathable fiber structure and a processing method thereon to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a radial tire with a breathable fiber structure, comprising a tire carcass, sidewalls fixedly bonded to both sides of the tire carcass, a tire crown fixedly bonded to the outer periphery of the tire carcass, and a breathable fiber layer disposed inside the tire crown and sidewalls.

[0010] A method for processing radial tires with a breathable fiber structure, the method being used to process radial tires with a breathable fiber structure using an extruder, the output end of the extruder being connected to a gear pump, the gear pump having two gears symmetrically rotatably connected inside, the gear pump comprising: The gear speed regulating unit is located on one side of the gear pump and is used to regulate the speed of the gears inside the gear pump and output the rubber material inside the extruder to the extrusion port; A temperature sensor is fixedly connected to the bottom of the gear pump's inner cavity and is used to detect the temperature of the rubber material inside the gear pump. A liquid level sensor is fixedly connected to the upper side wall of the inner cavity of the gear pump and is used to detect the height of the rubber material inside the gear pump. The gear pump extrusion port is equipped with an adjustment module that adjusts the cross-sectional area of ​​the gear pump extrusion port according to the temperature signal received by the temperature sensor.

[0011] Preferably, the extruder includes: The screw speed regulating unit is used to adjust the screw speed and extrude the rubber material through a spiral extrusion into the gear pump; Temperature control unit, used to adjust the temperature value inside the extruder cavity.

[0012] Preferably, the processing method includes the following steps: S1: Raw material processing and conveying: Rubber raw materials, breathable fiber layers, etc. enter the extruder through the feed inlet. The parameters are adjusted to the speed and temperature that meet the processing requirements by the screw speed adjustment unit and the temperature adjustment unit, and the processed mixed rubber material is conveyed to the gear pump. S2: Mixed rubber material conveying: The mixed rubber material enters the gear pump, and the gear speed adjustment unit adjusts the gear parameters to the speed that meets the processing requirements before conveying the rubber material to the gear pump extrusion port; S3: Temperature detection: The temperature of the rubber compound in the gear pump is detected by a temperature sensor; S4: Liquid level detection: The liquid level of the adhesive in the gear pump is detected by a liquid level sensor; S5: Finished rubber extrusion: The adjustment module adjusts the size of the gear pump extrusion nozzle by adjusting the rubber temperature value, so that the shrinkage of the extruded rubber after cooling to room temperature meets the usage requirements.

[0013] Preferably, if the temperature sensor detects that the temperature of the rubber compound is a predetermined value, the adjustment module does not adjust the size of the gear pump extrusion port, and the gear pump speed remains unchanged; while if the liquid level sensor detects that the liquid level of the rubber compound is higher than the predetermined value but within the predetermined range, the screw speed is reduced by the screw speed adjustment unit. If the temperature sensor detects that the temperature of the rubber compound is a predetermined value, the adjustment module will not adjust the size of the gear pump extrusion nozzle, and the speed of the gear pump will remain unchanged; if the liquid level sensor detects that the liquid level of the rubber compound is a predetermined value, the current parameters will be maintained and the machine will continue to operate. If the temperature sensor detects that the temperature of the rubber compound is a predetermined value, the adjustment module will not adjust the size of the gear pump extrusion port, and the gear pump speed will remain unchanged; however, if the level sensor detects that the level of the rubber compound is lower than the predetermined value but within the predetermined range, the screw speed will be increased by the screw speed adjustment unit.

[0014] Preferably, if the temperature sensor detects that the temperature of the rubber compound is higher than a predetermined value but within a predetermined range, the temperature inside the extruder is reduced by the temperature regulation unit, the adjustment module increases the extrusion port area of ​​the gear pump, and the gear speed of the gear pump is increased; and if the liquid level sensor detects that the liquid level of the rubber compound is a predetermined value, the screw speed of the extruder is increased, and the increase in the gear speed of the gear pump is equal to the increase in the screw speed of the extruder. If the temperature sensor detects that the rubber material temperature is higher than the predetermined value but within the predetermined range, the temperature inside the extruder is reduced by the temperature regulation unit, the adjustment module increases the extrusion port area of ​​the gear pump, and the gear speed of the gear pump is increased; if the liquid level sensor detects that the rubber material liquid level is lower than the predetermined value but within the predetermined range, the extruder screw speed is increased, and the increase in the gear speed of the gear pump is less than the increase in the extruder screw speed.

[0015] Preferably, if the temperature sensor detects that the temperature of the rubber compound is lower than a predetermined value but within a predetermined range, the temperature inside the extruder is increased by the temperature regulation unit, the gear pump extrusion port area is reduced by the adjustment module, and the gear pump speed is reduced. If the liquid level sensor detects that the liquid level of the rubber compound is a predetermined value, the extruder screw speed is reduced, and the reduction in the gear pump speed is equal to the reduction in the extruder screw speed. If the temperature sensor detects that the rubber temperature is lower than the predetermined value but within the predetermined range, the temperature inside the extruder is increased by the temperature regulation unit, the gear pump extrusion port area is reduced by the adjustment module, and the gear pump speed is reduced. If the liquid level sensor detects that the rubber liquid level is higher than the predetermined value but within the predetermined range, the extruder screw speed is reduced, and the reduction in gear pump speed is less than the reduction in extruder screw speed.

[0016] Preferably, if the temperature sensor detects that the temperature of the rubber compound is higher than a predetermined value but within a predetermined range, and the liquid level sensor detects that the liquid level of the rubber compound is higher than a predetermined value but within a predetermined range, then the machine is stopped to clear the blockage of the gear pump. If the temperature sensor detects that the rubber temperature is lower than the predetermined value but within the predetermined range, and the liquid level sensor detects that the rubber liquid level is lower than the predetermined value but within the predetermined range, then the extruder will be stopped to clear the blockage.

[0017] Preferably, if the temperature sensor detects that the temperature of the rubber compound is within a predetermined range while the liquid level sensor detects that the liquid level of the rubber compound is not within a predetermined range, the machine is stopped for inspection and maintenance of the screw speed regulating unit and the gear speed regulating unit. If the temperature sensor detects that the temperature of the rubber compound is outside the predetermined range while the liquid level sensor detects that the liquid level of the rubber compound is within the predetermined range, the machine should be stopped and the temperature regulation unit should be inspected. If the temperature sensor detects that the temperature of the adhesive material is outside the predetermined range, and the liquid level sensor detects that the liquid level of the adhesive material is outside the predetermined range, the machine should be stopped for maintenance.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention adjusts the size of the extrusion port area synchronously by adjusting the signal received from the temperature sensor by the adjustment module, so that the shape of the rubber material processed to different temperatures can be maintained within a predetermined range after cooling to room temperature.

[0019] 2. This invention uses a combination of temperature and liquid level sensors, and through dual judgment logic, it can determine the cause of abnormal data and adjust the parameters through the control system.

[0020] 3. By setting up a gear speed adjustment unit, this invention avoids the problems of gear pump buildup or bubble generation when temperature changes cause the adjustment module to change the cross-sectional area of ​​the extrusion port. It also adjusts the speed of the gear pump and the extruder screw according to the situation, thereby avoiding the generation of blockage bubbles and matching the extrusion efficiency with the change of the extrusion port area.

[0021] 4. By using temperature and liquid level sensors in combination, this invention can quickly determine the blockage and problems with the device itself by observing parameter changes when special abnormalities are detected or the detected values ​​are outside the predetermined range, and then stop and adjust the device to avoid damage caused by the device being in a problematic operating condition for a long time.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0025] like Figures 1 to 4 As shown, a radial tire with a breathable fiber structure includes a carcass 101, which is the core skeleton of the tire and equivalent to the tire's "load-bearing support". It is mainly composed of cord and rubber composite. Sidewalls 102 are fixedly bonded to both sides of the carcass 101. The sidewalls 102 are the flexible rubber parts on both sides of the tire and are the tire's "buffer and protective layer". A crown 103 is fixedly bonded to the outer periphery of the carcass 101. The crown 103 is the part of the tire that directly contacts the ground and is also the part that wears the fastest. It is composed of tread rubber, belt layer, etc. Breathable fiber layers 104 are provided inside the crown 103 and the sidewalls 102, which are mainly used to optimize the tire's air permeability and moisture wicking performance, improve structural stability and service durability.

[0026] A method for processing radial tires with a breathable fiber structure is disclosed. The method involves processing radial tires with a breathable fiber structure using an extruder 2. The output end of the extruder 2 is connected to a gear pump 3. Two gears are symmetrically rotatably connected inside the gear pump 3. These gears rotate inside the gear pump 3 to continuously convey the internal rubber material. A gear speed adjustment unit 301, located on one side of the gear pump 3, adjusts the speed of the gears inside the gear pump 3 and outputs the internal rubber material from the extruder 2 through the extrusion port. A temperature sensor 302 is fixedly connected to the bottom of the inner cavity of the gear pump 3 to detect the temperature of the internal rubber material. A liquid level sensor 303 is fixedly connected to the upper side wall of the inner cavity of the gear pump 3 to detect the liquid level height of the internal rubber material.

[0027] An adjustment module 4 is movably installed at the extrusion port of the gear pump 3. The cross-sectional area of ​​the extrusion port of the gear pump 3 is adjusted according to the temperature signal received by the temperature sensor 302. The adjustment module 4 includes a telescopic component and an adjustment plate. The telescopic component can change its extension distance according to the temperature value received by the temperature sensor 302. When the temperature is higher than a predetermined value but within a predetermined range, the extension length of the telescopic component shortens, causing the adjustment plate to move down to increase the extrusion port area. Since the rubber material has the principle of thermal expansion and contraction, and the greater the temperature difference of the rubber material, the greater the volume reduction after cooling to room temperature, the adjustment module 4 increases the opening so that the rubber material processed to different temperatures can be extruded along the adjustment module 4 and the shape of the rubber material can be maintained within the predetermined range after cooling to room temperature.

[0028] The extruder 2 includes a screw speed regulating unit 201 for regulating the screw speed and extruding the rubber material into the gear pump 3 by spiral extrusion; a temperature regulating unit 202 for regulating the internal temperature of the extruder 2; the extruder 2 also includes a control system, which can receive signals from the extruder 2, the gear pump 3 and the regulating module 4 and respond to control the screw speed, the internal temperature of the extruder 2 and the gear speed of the gear pump 3.

[0029] Rubber raw materials and breathable fiber layer 104 enter the feed inlet. The temperature is adjusted to a suitable temperature for the rubber compound to melt by the continuous rotation of the screw and the temperature adjustment unit 202 of the extruder 2. The rubber compound is extruded by screw extrusion. Under the action of screw extrusion and rotation and temperature heating, the rubber raw materials and breathable fiber layer 104 melt together and enter the gear pump 3 through the extrusion port of the extruder 2. Under the action of the gears of the gear pump 3, the output is stable and without pulsation.

[0030] The processing method for radial tires with a breathable fiber structure includes the following steps: S1: Raw material processing and conveying: Rubber raw materials and breathable fiber materials 104 enter the extruder 2 through the feed port. The parameters are adjusted to the speed and temperature that meet the processing requirements by the screw speed adjustment unit 201 and the temperature adjustment unit 202, and the processed mixed rubber material is conveyed to the gear pump 3.

[0031] S2: Mixed rubber material conveying: The mixed rubber material enters the gear pump 3. The gear speed adjustment unit 301 adjusts the gear parameters to a speed that meets the processing requirements and then conveys the rubber material to the extrusion port of the gear pump 3.

[0032] S3: Temperature detection: The temperature of the rubber compound in the gear pump 3 is detected by temperature sensor 302.

[0033] S4: Liquid level detection: The liquid level of the adhesive in the gear pump 3 is detected by the liquid level sensor 303.

[0034] S5: Finished rubber extrusion: Adjusting module 4 adjusts the size of the extrusion nozzle of gear pump 3 by adjusting the rubber temperature value, so that the shrinkage of the extruded rubber after cooling to room temperature meets the usage requirements.

[0035] During the radial tire manufacturing process, the breathable fiber layer 104 needs to be processed into the tread 103 and sidewall 102 of the radial tire 1. The rubber raw material and the breathable fiber layer 104 are fed into the feed port. The screw speed regulating unit 201 in the extruder 2 rotates continuously, and the temperature regulating unit 202 adjusts the temperature to a suitable temperature for the rubber compound to melt. Under the action of screw extrusion and rotation and temperature heating, the rubber raw material and the breathable fiber layer 104 will melt together. As the screw continues to rotate, the rubber compound will be carried into the gear pump 3. The gear set inside the gear pump 3 will smoothly and without pulsation extrude the rubber compound through the extrusion port of the gear pump 3. The temperature sensor 302 set at the bottom of the gear pump 3 will detect the temperature of the rubber compound inside the gear pump 3 in real time, while the liquid level sensor 303 will detect the liquid level of the rubber compound inside the gear pump 3 in real time.

[0036] When an abnormal temperature change occurs, it is fed back to the control system. The temperature inside the extruder 2 is then adjusted to ensure that subsequent processing meets the requirements. The adjustment module 4 adjusts the size of the extrusion port of the gear pump 3 based on the temperature value sensed by the temperature sensor 302. When the temperature is higher than the predetermined value but within the predetermined range, the adjustment module 4 increases the opening area, resulting in a larger cross-sectional area after the rubber is extruded. This results in a larger amount of shrinkage after cooling to room temperature, while the cross-sectional area after shrinkage still meets the requirements. When the temperature is lower than the predetermined value but within the predetermined range, the adjustment module 4 decreases the opening area, resulting in a smaller cross-sectional area after the rubber is extruded. This also results in a smaller amount of shrinkage, while the cross-sectional area after shrinkage still meets the requirements. When the temperature is at the predetermined value, the adjustment module 4 does not operate, ensuring that the cross-sectional area after the rubber is extruded is the predetermined cross-sectional area and the cross-sectional area after shrinkage is the predetermined value. Example 2

[0037] Although the above solution can adjust the size of the extrusion nozzle area by adjusting the module 4 based on the temperature of the temperature sensor 302, in actual production, there will be a situation where the temperature of the rubber material is stable but the liquid level fluctuates. At this time, the adjustment method that relies solely on the temperature signal cannot accurately match the extrusion requirements of the rubber material, which can easily lead to problems of excessive or insufficient extrusion and ultimately affect the shape quality after cooling to room temperature.

[0038] If the temperature sensor 302 detects that the temperature of the rubber compound is a predetermined value and the liquid level sensor 303 detects that the liquid level of the rubber compound is higher than the predetermined value but within the predetermined range, the screw speed is reduced by the screw speed adjustment unit 201, and the adjustment module 4 does not adjust the size of the extrusion port of the gear pump 3.

[0039] If the temperature sensor 302 detects that the temperature of the rubber material is a predetermined value, the adjustment module 4 does not adjust the size of the extrusion port of the gear pump 3, and the speed of the gear pump 3 remains unchanged; if the liquid level sensor 303 detects that the liquid level of the rubber material is higher than the predetermined value but within the predetermined range, the screw speed is reduced by the screw speed adjustment unit 201.

[0040] If the temperature sensor 302 detects that the temperature of the rubber compound is a predetermined value, the adjustment module 4 will not adjust the size of the extrusion port of the gear pump 3, and the speed of the gear pump 3 will remain unchanged; while if the liquid level sensor 303 detects that the liquid level of the rubber compound is a predetermined value, it will maintain the current parameters and continue to work.

[0041] If the temperature sensor 302 detects that the temperature of the rubber material is a predetermined value, the adjustment module 4 will not adjust the size of the extrusion port of the gear pump 3, and the speed of the gear pump 3 will remain unchanged; while if the liquid level sensor 303 detects that the liquid level of the rubber material is lower than the predetermined value but within the predetermined range, the screw speed will be increased by the screw speed adjustment unit 201.

[0042] Therefore, in actual use, when the temperature sensor 302 inside the gear pump 3 detects that the temperature of the rubber material is the predetermined value, it means that the shape of the rubber material inside the gear pump 3 meets the requirements after being discharged from the extrusion port and cooled to room temperature. In this case, there is no need to adjust the adjustment module 4. If the liquid level sensor 303 inside the gear pump 3 detects that the liquid level value is equal to the predetermined value, it means that all parameters of the device are normal at this time, and the current parameters are maintained to continue working.

[0043] When the temperature sensor 302 inside the gear pump 3 detects that the temperature of the rubber material is at a predetermined value, it means that the shape of the rubber material inside the gear pump 3 meets the requirements after being discharged from the extrusion port and cooled to room temperature. Therefore, there is no need to adjust the adjustment module 4. If the liquid level sensor 303 inside the gear pump 3 detects that the temperature is lower than the predetermined value but within the predetermined range, it can be determined that the screw speed inside the extruder 2 is slow, causing the rubber material conveyed by the extruder 2 to be quickly extruded by the gears in the gear pump 3. Then, the screw speed is increased by the screw speed adjustment unit 201 so that the screw conveying efficiency matches the extrusion efficiency of the gears to meet the subsequent processing requirements.

[0044] When the temperature sensor 302 inside the gear pump 3 detects that the temperature of the rubber material is a predetermined value, it means that the shape of the rubber material inside the gear pump 3 meets the requirements after being discharged from the extrusion port and cooled to room temperature. Therefore, there is no need to adjust the adjustment module 4. If the liquid level sensor 303 inside the gear pump 3 detects that the temperature is higher than the predetermined value but within the predetermined range, it can be determined that the screw speed inside the extruder 2 is too fast, causing the rubber material conveyed by the extruder 2 to be slowly extruded by the gear. Then, the screw speed is reduced by the screw speed adjustment unit 201 so that the screw conveying efficiency matches the extrusion efficiency of the gear to meet the subsequent processing requirements. Example 3

[0045] Although the above solution can adjust the size of the extrusion port area according to the temperature of the temperature sensor 302 using the adjustment module 4, so that the shape of the rubber material processed to different temperatures can be maintained within a predetermined range after being extruded along the adjustment module 4 and cooled to room temperature, during the process of adjusting the extrusion port area of ​​the gear pump 3, if the gear speed of the gear pump 3 itself does not change due to the change in the volume of the extrusion port, the amount of rubber material discharged inside the gear pump 3 will not match the change in the volume of the extrusion port, resulting in problems such as rubber material accumulation or air bubbles in the extrusion port. Furthermore, if the amount of rubber material entering the gear pump 3 along the extruder 2 and the conveying speed cannot be adjusted, the amount of rubber material inside the gear pump 3 will change and affect the subsequent normal conveying effect.

[0046] To solve the above technical problems, the following improvements are made based on Embodiment 1: If the temperature sensor 302 detects that the temperature of the rubber compound is higher than the predetermined value but within the predetermined range, the temperature inside the extruder 2 is reduced by the temperature regulating unit 202, the regulating module 4 increases the extrusion port area of ​​the gear pump 3, and the gear speed of the gear pump 3 is increased; while if the liquid level sensor 303 detects that the liquid level of the rubber compound is the predetermined value, the screw speed of the extruder 2 is increased, and the increase in the gear speed of the gear pump 3 is equal to the increase in the screw speed of the extruder 2. If the temperature sensor 302 detects that the temperature of the rubber compound is higher than the predetermined value but within the predetermined range, the temperature adjustment unit 202 reduces the temperature inside the extruder 2, the adjustment module 4 increases the extrusion port area of ​​the gear pump 3, and increases the gear speed of the gear pump 3; while if the liquid level sensor 303 detects that the liquid level of the rubber compound is lower than the predetermined value but within the predetermined range, the screw speed of the extruder 2 is increased, and the increase in the gear speed of the gear pump 3 is less than the increase in the screw speed of the extruder 2.

[0047] If the temperature sensor 302 detects that the temperature of the rubber compound is lower than the predetermined value but within the predetermined range, the temperature adjustment unit 202 increases the temperature inside the extruder 2, the adjustment module 4 reduces the extrusion port area of ​​the gear pump 3, and the gear speed of the gear pump 3 decreases. If the liquid level sensor 303 detects that the liquid level of the rubber compound is the predetermined value, the screw speed of the extruder 2 is reduced, and the reduction in the gear speed of the gear pump 3 is equal to the reduction in the screw speed of the extruder 2. If the temperature sensor 302 detects that the temperature of the rubber compound is lower than the predetermined value but within the predetermined range, the temperature adjustment unit 202 increases the temperature inside the extruder 2, the adjustment module 4 reduces the extrusion port area of ​​the gear pump 3, and the gear speed of the gear pump 3 decreases. If the liquid level sensor 303 detects that the liquid level of the rubber compound is higher than the predetermined value but within the predetermined range, the screw speed of the extruder 2 decreases, and the decrease in the gear speed of the gear pump 3 is less than the decrease in the screw speed of the extruder 2.

[0048] During the processing of radial tires with breathable fiber structure, the adjustment module 4 adjusts the extrusion port area of ​​the gear pump 3, which will change the volume of the extrusion port. The control system adjusts the front-end step parameters to ensure that the subsequent operation meets the requirements, and the gear speed adjustment unit 301 adjusts the gear speed to keep the current processing process within a controllable range and ensure that the subsequent processing parameters meet the processing requirements.

[0049] When the temperature value detected by the temperature sensor 302 is higher than the predetermined value but within the predetermined range, the adjustment module 4 increases the extrusion port area of ​​the gear pump 3, so that the cross-sectional area of ​​the extruded rubber is larger. This results in a larger amount of shrinkage after cooling to room temperature, while the cross-sectional area after shrinkage still meets the requirements. At the same time, the temperature inside the extruder 2 is reduced by the temperature adjustment unit 202 to ensure the stability of the subsequent rubber temperature. The gear speed adjustment unit 301 correspondingly increases the rotation of the gear inside the gear pump 3, so that the discharge volume of the rubber inside the gear pump 3 matches the increase in the extrusion port area of ​​the gear pump 3, effectively ensuring the continuous and stable discharge of the rubber inside the gear pump 3.

[0050] If the liquid level sensor 303 detects a value lower than the predetermined value but within the predetermined range, it can be determined that the screw speed inside the extruder 2 is slow. Therefore, the screw speed adjustment unit 201 increases the screw speed of the extruder 2 accordingly, and the increase in the gear speed of the gear pump 3 is less than the increase in the screw speed of the extruder 2. This ensures that the rubber extrusion efficiency meets the requirements of the increased extrusion orifice area while also allowing the liquid level to rise, thereby satisfying the actual rubber extrusion effect.

[0051] If the liquid level sensor 303 detects that the liquid level is within the predetermined range, it can be determined that the screw speed inside the extruder 2 is stable. Therefore, the screw speed adjustment unit 201 increases the screw speed of the extruder 2 accordingly, and the increase in the gear speed of the gear pump 3 is equal to the increase in the screw speed of the extruder 2. This ensures that the extrusion efficiency meets the increased extrusion orifice area and avoids the formation of air bubbles at the extrusion orifice due to the sudden increase in the extrusion orifice area.

[0052] When the temperature sensor 302 detects that the temperature of the extruded material is lower than a predetermined value but within a predetermined range, the regulating module 4 reduces the opening area, resulting in a smaller cross-sectional area after extrusion. This minimizes shrinkage upon cooling to room temperature, while maintaining the required cross-sectional area. Simultaneously, the temperature regulating unit 202 raises the temperature inside the extruder 2 to ensure the stability of the subsequent extruded material temperature. The gear speed regulating unit 301 correspondingly reduces the rotation of the gears inside the gear pump 3, ensuring that the discharge rate of the extruded material from the gear pump 3 matches the reduction in the extrusion opening area, effectively guaranteeing a continuous and stable discharge of the extruded material from the gear pump 3. If the liquid level sensor 303 detects a value higher than the predetermined value but within the predetermined range, it can be determined that the screw speed inside the extruder 2 is too fast. Therefore, the screw speed adjustment unit 201 reduces the screw speed of the extruder 2 accordingly, and the reduction in the gear speed of the gear pump 3 is less than the reduction in the screw speed of the extruder 2. This makes the rubber extrusion efficiency of the gear pump 3 greater than the transmission efficiency from the extruder 2 to the gear pump 3, thus avoiding blockage inside the gear pump 3 due to the accumulation of rubber.

[0053] If the liquid level sensor 303 detects that the liquid level is within the predetermined range, it can be determined that the screw speed inside the extruder 2 is stable. Therefore, the screw speed adjustment unit 201 reduces the screw speed of the extruder 2 accordingly, and the reduction in the gear speed of the gear pump 3 is equal to the reduction in the screw speed of the extruder 2, so that the extrusion efficiency of the gear pump 3 matches the size of the extrusion port, thereby making the rubber material inside the gear pump 3 extruded at a uniform speed. Example 4

[0054] During the heating and conveying of the rubber compound by the extruder 2, blockages may still occur inside the extruder 2 or gear pump 3. However, relying solely on the single temperature detection of the existing device cannot accurately determine the occurrence of blockages, ultimately affecting the normal and continuous discharge of subsequent rubber compounds. At the same time, the extruder 2 or gear pump 3 is also prone to structural damage during prolonged use. These damaged units include the gear speed adjustment unit 301, the screw speed adjustment unit 201, and the temperature adjustment unit 202, which in turn affect the normal discharge of subsequent rubber compounds. Existing technologies cannot quickly determine the location of the damage, thus increasing the difficulty of maintenance.

[0055] If the temperature sensor 302 detects that the temperature of the rubber compound is higher than the predetermined value but within the predetermined range, and the liquid level sensor 303 detects that the liquid level of the rubber compound is higher than the predetermined value but within the predetermined range, then the machine will be stopped to clear the blockage of the gear pump 3.

[0056] If the temperature sensor 302 detects that the temperature of the rubber compound is lower than the predetermined value but within the predetermined range, and the liquid level sensor 303 detects that the liquid level of the rubber compound is lower than the predetermined value but within the predetermined range, then the extruder 2 will be stopped to clear the blockage.

[0057] If the temperature sensor 302 detects that the temperature of the rubber compound is within the predetermined range, while the liquid level sensor 303 detects that the liquid level of the rubber compound is not within the predetermined range, the machine will be stopped for maintenance of the screw speed regulating unit 201 and the gear speed regulating unit 301.

[0058] If the temperature sensor 302 detects that the temperature of the adhesive material is not within the predetermined range, while the liquid level sensor 303 detects that the liquid level of the adhesive material is within the predetermined range, the machine will be stopped for maintenance of the temperature regulation unit 202.

[0059] If the temperature sensor 302 detects that the temperature of the rubber compound is not within the predetermined range and the liquid level sensor 303 detects that the liquid level of the rubber compound is not within the predetermined range, the machine will be stopped for maintenance.

[0060] In actual use, when the temperature value detected by the temperature sensor 302 is higher than the predetermined value but within the predetermined range, the adjustment module 4 increases the extrusion port area of ​​the gear pump 3, and the temperature inside the extruder 2 is reduced by the temperature adjustment unit 202. The gear speed adjustment unit 301 correspondingly increases the rotation of the gear inside the gear pump 3. Therefore, under normal circumstances, the amount of rubber inside the gear pump 3 will continuously decrease. However, if the liquid level sensor 303 detects that it is also higher than the predetermined value but within the predetermined range, it can be determined that there is a blockage inside the gear pump 3. The rubber inside the gear pump 3 cannot be discharged normally through the extrusion port, and the rubber inside the extruder 2 continuously enters the gear pump 3, causing its liquid level to rise continuously. This results in the rubber not being discharged normally inside the gear pump 3 and affecting subsequent work. In this case, the problem cannot be solved and the device can continue to work by changing the device parameters. Therefore, it is necessary to stop the machine immediately to clear the blockage of the gear pump 3 to prevent the rubber from continuing to accumulate inside the gear pump 3 and affecting its own structure, or even hindering the normal operation of the gear inside the gear pump 3. After solving the problem, the machine is restarted to resume operation.

[0061] When the temperature value detected by the temperature sensor 302 is lower than the predetermined value but within the predetermined range, the adjustment module 4 reduces the extrusion port area of ​​the gear pump 3, and the temperature inside the extruder 2 is increased by the temperature adjustment unit 202. The gear speed adjustment unit 301 correspondingly reduces the rotation of the gear inside the gear pump 3. Therefore, under normal circumstances, the rubber material inside the gear pump 3 will continuously increase. If the liquid level sensor 303 detects that the temperature is lower than the predetermined value but within the predetermined range, it can be determined that there is a blockage inside the extruder 2. Therefore, the amount of rubber material entering the gear pump 3 inside the extruder 2 decreases, causing the liquid level of the rubber material inside the gear pump 3 to drop. In this case, the device cannot be fixed by changing the device parameters and can continue to work. Therefore, it is necessary to stop the machine immediately to clear the blockage in the extruder 2 to prevent the rubber material from being continuously heated inside the extruder 2 and unable to be extruded, which would damage the device. After the problem is solved, the machine can be restarted to resume operation.

[0062] When temperature sensor 302 detects that the rubber compound temperature is outside the predetermined range, it indicates that the temperature inside extruder 2 is also outside the predetermined range, meaning that temperature regulation unit 202 has failed and cannot accurately regulate the processing temperature inside extruder 2 to meet the working requirements. Therefore, the machine should be stopped for maintenance of temperature regulation unit 202. Similarly, when level sensor 303 detects that the rubber compound level is outside the predetermined range, it indicates that the screw speed inside extruder 2 or the gear speed inside gear pump 3 is also outside the predetermined range, meaning that screw speed regulation unit 201 or gear speed regulation unit 301 has failed and cannot accurately regulate the screw speed to meet the working requirements. Therefore, the machine should be stopped for maintenance of screw speed regulation unit 201 or gear speed regulation unit 301. When both temperature sensor 302 and level sensor 303 detect that the rubber compound temperature and level are outside the predetermined range, the entire machine is considered to be malfunctioning. Therefore, the machine needs to be stopped for maintenance, and after resolving the problem, it should be restarted for operation.
