Description

Technical Field

[0001] This application relates to the field of automated production technology, and more specifically, to a control method and apparatus for an extrusion extruder. Background Technology

[0002] In the production of rubber products, especially tires, adjusting the operating parameters of the extrusion extruder is crucial to ensuring production efficiency and product quality. Traditional extrusion operations rely on the operator's experience to manually match the screw speed and linear speed. This manual method is not only inconsistent but also prone to dimensional deviations when specifications are changed or production conditions change, increasing the production of defective products and thus affecting production efficiency and cost control.

[0003] In recent years, to overcome the limitations of manual operation, the industry has begun to introduce a "one-click start" mode. This mode calculates the extruder screw speed by correlating the preset average extrusion volume with the product specifications, thereby reducing the defect rate caused by human factors. However, in related technologies, the screw speed calculation is often based on the final average extrusion volume, ignoring the non-linear impact of product size on the extrusion volume. This leads to deviations in the settings of extrusion volume and product width when producing different specifications, increasing waste and adjustment time during specification switching, and reducing production flexibility and efficiency. Furthermore, even in the "one-click start" mode, the setting of the linkage speed is difficult to adapt to the dynamic changes in the on-site production process. For example, while waiting for the tooling trolley or the supply of rubber, operators need to manually adjust the main extrusion speed and linkage speed to avoid dimensional fluctuations. This not only increases operational complexity but also makes it difficult to ensure precise speed matching, thereby increasing the risk of dimensional fluctuations in product components and further affecting production continuity and product quality.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0005] This application provides a control method and apparatus for an extrusion extruder, which at least solves the technical problem that the working parameters of the extrusion extruder need to be manually adjusted during the production of rubber products, resulting in low efficiency and difficulty in ensuring product quality.

[0007] Optionally, determining the first extruded amount of adhesive by the extruder per unit time based on the first linkage linear speed and the first processing weight per meter includes: using the product of the first linkage linear speed and the first processing weight per meter as the first extruded amount of adhesive by the extruder per unit time.

[0008] Optionally, the configuration process of the first linear relationship includes: acquiring multiple sets of first production record data corresponding to various specifications of rubber products, wherein each set of first production record data includes: the screw speed of the extruder and the amount of rubber extruded per unit time when producing a rubber product of a certain specification; using the amount of rubber extruded per unit time as the independent variable and the screw speed as the dependent variable, performing linear fitting on the multiple sets of first production record data to obtain the first linear relationship.

[0009] Optionally, the configuration process of the second linear relationship includes: acquiring multiple sets of second production record data corresponding to rubber products of various specifications with qualified widths, wherein the rubber products with qualified widths are rubber products whose width after processing by the processing equipment is the same as the preset product width, and each set of second production record data includes: the extrusion width of the extruder and the width of the rubber product processed by the processing equipment when producing a rubber product of a certain specification with qualified widths; using the width of the rubber product as the independent variable and the extrusion width as the dependent variable, performing linear fitting on the multiple sets of second production record data to obtain the second linear relationship.

[0010] Optionally, the raw material state and product state of the target rubber product are periodically acquired, wherein the raw material state includes the remaining amount of raw material, and the product state includes the second product width of the target rubber product produced; the screw speed of the extruder and the linkage linear speed of the transmission equipment are adjusted based on the raw material state and product state.

[0011] Optionally, adjusting the screw speed of the extruder and the linkage linear speed of the transmission device based on the raw material state and the product state includes: entering a first adjustment mode when the absolute difference between the second product width and the first product width is not greater than a first preset threshold, wherein in the first adjustment mode, the screw speed of the extruder and the linkage linear speed of the transmission device are increased or decreased based on a preset step size; and entering a second adjustment mode when the absolute difference between the second product width and the first product width is greater than the first preset threshold, wherein in the second adjustment mode, the screw speed of the extruder remains unchanged, and the linkage linear speed of the transmission device is increased or decreased.

[0012] Optionally, entering the first adjustment mode includes: when the remaining raw material amount is not less than a second preset threshold, determining a first preset multiple of the screw speed of the extruder in the previous cycle as the second screw speed, substituting the second screw speed into a first linear relationship to obtain the second extruded amount of rubber from the extruder, and determining the second linkage linear speed of the transmission equipment based on the second extruded amount of rubber and the first processed weight per meter, wherein the first preset multiple is greater than 1; when the second screw speed is not greater than a preset upper limit of screw speed, adjusting the screw speed of the extruder to the second screw speed, and adjusting the linkage linear speed of the transmission equipment to the second linkage linear speed; when the second screw speed is greater than the preset upper limit of screw speed, not adjusting the screw speed of the extruder. The linkage linear speed of the extruder and the conveying equipment; when the remaining raw material is less than the second preset threshold, the second preset multiple of the screw speed of the extruder in the previous cycle is determined as the third screw speed. The third screw speed is substituted into the first linear relationship to obtain the third extruded rubber amount of the extruder. Based on the third extruded rubber amount and the first processed weight per meter, the third linkage linear speed of the conveying equipment is determined, wherein the second preset multiple is less than 1; when the third screw speed is not less than the first screw speed, the screw speed of the extruder is adjusted to the third screw speed, and the linkage linear speed of the conveying equipment is adjusted to the third linkage linear speed; when the third screw speed is less than the first screw speed, the screw speed of the extruder and the linkage linear speed of the conveying equipment are not adjusted.

[0013] According to another aspect of the embodiments of this application, a control device for an extrusion extruder is also provided, comprising: an acquisition module, configured to acquire a first linkage linear speed preset by a transmission device, a first processing weight per meter preset by a processing device, and a first product width preset by a target rubber product when producing a target rubber product, wherein the transmission device is configured to transmit the rubber material extruded by the extrusion extruder to the processing device for processing to obtain a rubber product; a determination module, configured to determine a first extruded rubber amount per unit time by the extrusion extruder based on the first linkage linear speed and the first processing weight per meter; a first calculation module, configured to substitute the first extruded rubber amount into a first linear relationship between the screw speed of the extrusion extruder and the extruded rubber amount preset to obtain a first screw speed of the extrusion extruder; a second calculation module, configured to substitute the first product width into a second linear relationship between the extrusion width of the extrusion extruder preset to the width of the rubber product processed by the processing device preset to obtain a first extrusion width of the extrusion extruder; and a control module, configured to control the extrusion extruder to perform rubber material extrusion based on the first screw speed and the first extrusion width.

[0016] In this embodiment, by collecting relevant data from the production process of various specifications of rubber products and performing linear fitting, a linear relationship can be obtained between the screw speed and rubber output of a multi-specification universal extrusion extruder, as well as a linear relationship between the extrusion width of the extrusion extruder and the width of the rubber product processed by the processing equipment. Subsequently, during the production of rubber products, it is only necessary to substitute the parameters of the rubber product to be produced and the pre-configured parameters of the transmission equipment and processing equipment into the above linear relationship to obtain the working parameters to be set for the extrusion extruder, including the screw speed and extrusion width. During the production process, the screw speed of the extrusion extruder and the linkage linear speed of the transmission equipment can be automatically adjusted according to the actual production status, while ensuring the quality of the rubber products. The entire production process is automated and requires no manual intervention, which can greatly improve the production efficiency of rubber products. In other words, this solution effectively solves the technical problem that the working parameters of the extrusion extruder need to be manually adjusted during the production of rubber products, resulting in low efficiency and difficulty in ensuring product quality.

[0025] Example 1

[0026] According to an embodiment of this application, a control method for an extrusion extruder is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0027] Figure 1 This is a schematic flowchart of a control method for an extrusion extruder according to an embodiment of this application, as shown below. Figure 1 As shown, the method includes the following steps:

[0028] Step S102: When producing the target rubber product, the first linkage linear speed preset by the conveying equipment, the first processing weight per meter preset by the processing equipment, and the first product width preset by the target rubber product are obtained. The conveying equipment is used to convey the rubber material extruded by the extruder to the processing equipment for processing to obtain the rubber product.

[0029] Step S104: Determine the first extruded amount of rubber per unit time of the extruder based on the first linkage line speed and the first processing weight per meter;

[0030] Step S106: Substitute the first extruded amount of rubber into the first linear relationship between the screw speed and the extruded amount of rubber in the pre-configured extrusion extruder to obtain the first screw speed of the extrusion extruder;

[0031] Step S108: Substitute the first product width into the second linear relationship between the pre-configured extrusion width of the extrusion extruder and the width of the rubber product processed by the processing equipment to obtain the first extrusion width of the extrusion extruder.

[0032] Step S110: The extruder is controlled to perform rubber extrusion based on the first screw speed and the first extrusion width.

[0033] The following section explains the steps of the control method for the extrusion extruder in conjunction with the specific implementation process.

[0034] As an optional implementation, determining the first linear relationship between the screw speed of the extruder and the amount of rubber extruded can be achieved as follows: Multiple sets of first production record data corresponding to various specifications of rubber products are obtained, wherein each set of first production record data includes: the screw speed of the extruder and the amount of rubber extruded per unit time when producing a rubber product of a certain specification; the amount of rubber extruded per unit time is used as the independent variable and the screw speed as the dependent variable, and a linear fit is performed on the multiple sets of first production record data to obtain the first linear relationship.

[0035] Understandably, to ensure that the fitted first linear relationship applies to rubber products of different specifications simultaneously, production record data for rubber products of various specifications (large, medium, and small) can be collected simultaneously for linear fitting. Specifically, for each specification of rubber product, the screw speed of the extruder and the amount of rubber extruded per unit time (e.g., per minute) during its production process can be obtained. Using the amount of rubber extruded per unit time as the independent variable and the screw speed as the dependent variable, multiple sets of data are linearly fitted to obtain the first linear relationship.

[0036] Considering that in some production scenarios, the screw speed of the extruders corresponding to rubber products of the same specifications is the same, we can take the average value of the extruded rubber amount per unit time for multiple rubber products of the same specifications and the screw speed of the extruder corresponding to that specification as a set of data. Figure 2 This diagram illustrates a fitting of the first linear relationship, where the horizontal axis represents the amount of rubber extruded per unit time, and the vertical axis represents the screw speed of the extruder. By performing linear fitting on three sets of data corresponding to large, medium, and small rubber products, the first linear relationship is obtained as y = 0.288x - 0.054, and the coefficient of determination R0 of the fitting result is... 2 =0.9998, indicating that the fitting result is reliable.

[0037] Optionally, when determining the second linear relationship between the extrusion width of the extruder and the width of the rubber product processed by the processing equipment, it can be achieved as follows: obtain multiple sets of second production record data corresponding to rubber products of various specifications with qualified widths, wherein the rubber product with qualified width is the rubber product whose width after processing by the processing equipment is the same as the preset product width, and each set of second production record data includes: the extrusion width of the extruder and the width of the rubber product processed by the processing equipment when producing a rubber product of a certain specification with qualified width; with the rubber product width as the independent variable and the extrusion width as the dependent variable, perform linear fitting on the multiple sets of second production record data to obtain the second linear relationship.

[0038] Similar to determining the first linear relationship, in order to ensure that the fitted second linear relationship is applicable to rubber products of different specifications, production record data of rubber products of various specifications such as large, medium and small can also be collected for linear fitting when collecting data. In addition, considering that the extrusion width of the extruder is closely related to the quality (width) of the final produced rubber product, the production record data collected here emphasizes that the rubber product as the subject of the data collection must have a qualified width. That is, after the rubber material extruded by the extruder at the set extrusion width is subjected to forced shrinkage, water cooling and winding operations by the processing equipment, the width of the final rubber product is the same as the expected width.

[0039] Figure 3This diagram illustrates a fitting of a second linear relationship. The horizontal axis represents the width of the rubber product processed by the equipment, and the vertical axis represents the extrusion width of the extruder. By performing linear fitting on multiple sets of data corresponding to various specifications of rubber products, the second linear relationship is obtained as y = 0.9644x + 5.1787, and the coefficient of determination R0 of the fitting result is... 2 =0.9991, indicating that the fitting result is reliable.

[0040] After obtaining the first and second linear relationships, they can be stored in the MES (Manufacturing Execution System) and integrated with the existing "one-click start" mode to achieve automated setting of the extruder's operating parameters.

[0041] As an optional implementation, when producing a target rubber product of a target specification, the first linkage linear speed pre-configured for the transmission equipment and the first processing weight per meter matching the target specification pre-configured for the processing equipment can be obtained from the relevant construction configuration table in the MES. At the same time, the first product width of the target rubber product specified by the target specification is determined.

[0042] Considering that the rubber extruded by the extruder is mainly transported by the conveying equipment and then processed by the processing equipment to perform operations such as forced shrinkage, water cooling, and winding to obtain rubber products, the loss in the whole process is small. Based on the law of conservation of mass, the product of the first linkage linear speed and the first processed meter weight can be used as the first extruded rubber amount of the extruder per unit time. Then, the first extruded rubber amount is substituted into the first linear relationship mentioned above to obtain the first screw speed of the extruder.

[0043] At the same time, the width of the first product can be directly substituted into the second linear relationship mentioned above to obtain the first extrusion width of the extruder.

[0044] Then, the calculated first screw speed and first extrusion width can be sent to the PLC (Programmable Logic Controller) of the extruder to control the extruder to perform rubber extrusion according to the set parameters.

[0045] In order to ensure that the quality of the produced rubber products can be strictly controlled during the production stage, while maximizing production efficiency and avoiding resource waste, this application embodiment further provides an automated adjustment mechanism for the screw speed of the extrusion extruder and the linkage linear speed of the transmission equipment.

[0046] As an optional implementation, the state of the raw materials and the state of the finished products can be acquired periodically, and the screw speed of the extruder and the linkage linear speed of the transmission equipment can be adjusted based on the state of the raw materials and the state of the finished products.

[0047] The data collection period can be set according to requirements. For example, if the time required to produce a target rubber product is determined based on historical data, the data collection period can be set to an integer multiple of that time. No specific limit is set here.

[0048] The status of raw materials mainly includes the amount of raw materials remaining, which can reflect the production stage of the target rubber product to a certain extent. For example, if there is a large amount of raw materials remaining, it means that the production is in the early or middle stage. If there is a small amount of raw materials remaining, it may be waiting for the tooling trolley to arrive, or there may be insufficient supply of rubber material. It may also be that the production of the target rubber product has entered the final stage, and it may be necessary to change the rubber material to produce other specifications of rubber products later.

[0049] The product status mainly includes the second product width of the target rubber product produced, which can be the average width of all target rubber products produced within a cycle, used to evaluate the quality of the target rubber product produced.

[0050] Optionally, when adjusting the screw speed of the extruder and the linkage linear speed of the transmission device based on the raw material and product conditions, this can be achieved as follows: If the absolute difference between the second product width and the first product width is not greater than a first preset threshold, a first adjustment mode is entered. In this first adjustment mode, the screw speed of the extruder and the linkage linear speed of the transmission device are increased or decreased based on a preset step size. If the absolute difference between the second product width and the first product width is greater than the first preset threshold, a second adjustment mode is entered. In this second adjustment mode, the screw speed of the extruder remains constant, while the linkage linear speed of the transmission device is increased or decreased. The aforementioned first preset threshold can be set based on production experience and is not specifically limited here.

[0051] Understandably, when the absolute difference between the width of the second product and the width of the first product is not greater than the first preset threshold, it means that the width error of the target rubber product is within an acceptable range, that is, the quality of the target rubber product is qualified. At this time, the main consideration is how to further improve production efficiency and avoid resource waste caused by waiting for tooling trolleys, etc. The screw speed of the extruder and the linkage linear speed of the transmission equipment can be finely adjusted appropriately.

[0052] As an optional implementation, in the first adjustment mode, when the remaining raw material is not less than the second preset threshold, a first preset multiple of the screw speed of the extruder in the previous cycle is determined as the second screw speed. The second screw speed is substituted into the first linear relationship to obtain the second extruded amount of rubber from the extruder. Based on the second extruded amount of rubber and the first processed weight per meter, the second linkage linear speed of the transmission device is determined, wherein the first preset multiple is greater than 1. When the second screw speed is not greater than the preset upper limit of screw speed, the screw speed of the extruder is adjusted to the second screw speed, and the linkage linear speed of the transmission device is adjusted to the second linkage linear speed. When the second screw speed is greater than the preset upper limit of screw speed, the screw speed of the extruder and the linkage linear speed of the transmission device are not adjusted.

[0053] Understandably, if the remaining amount of raw materials is not less than the second preset threshold, it means that there are enough raw materials remaining. At this time, the production of the target rubber products may have just begun. Therefore, under the premise of ensuring that the quality of the produced target rubber products is qualified, the screw speed of the extruder and the linkage linear speed of the transmission equipment can be slightly increased.

[0054] To ensure the stability of the control, the adjustment step size needs to be limited. For example, within each cycle, the screw speed of the extruder can be adjusted to 1.1 times the screw speed of the previous cycle. To ensure stable coordination between the transmission equipment and the extruder, the linkage linear speed of the transmission equipment needs to be increased simultaneously. In specific calculations, the adjusted second screw speed can be substituted into the first linear relationship to obtain the second extruded rubber volume. Since the premise of the adjustment is that the quality of the target rubber product produced is qualified, the first processing weight per meter of the processing equipment should remain basically unchanged. At this time, the ratio of the second extruded rubber volume to the first processing weight per meter can be used as the new second linkage linear speed of the transmission equipment. It should be noted that if the calculated second screw speed exceeds the upper limit of the screw speed, the first adjustment mode is exited, and the screw speed of the extruder and the linkage linear speed of the transmission equipment are no longer adjusted.

[0055] Optionally, in the first adjustment mode, when the remaining raw material is less than the second preset threshold, a second preset multiple of the screw speed of the extruder in the previous cycle is determined as the third screw speed. The third screw speed is substituted into the first linear relationship to obtain the third extruded amount of rubber from the extruder. Based on the third extruded amount of rubber and the first processed weight per meter, the third linkage linear speed of the transmission device is determined, wherein the second preset multiple is less than 1. When the third screw speed is not less than the first screw speed, the screw speed of the extruder is adjusted to the third screw speed, and the linkage linear speed of the transmission device is adjusted to the third linkage linear speed. When the third screw speed is less than the first screw speed, the screw speed of the extruder and the linkage linear speed of the transmission device are not adjusted.

[0056] Understandably, if the remaining amount of raw materials is less than the second preset threshold, it may indicate that the material is waiting for the tooling trolley to arrive, or that there is insufficient supply of rubber material, or that the production of the target rubber product has entered the final stage and it may be necessary to change the rubber material to produce other specifications of rubber products. In any case, it is necessary to appropriately reduce the screw speed and the linkage linear speed of the transmission equipment to avoid increasing the amount of scrap due to improper equipment coordination, which would result in a waste of resources.

[0057] To ensure the stability of the control, the adjustment step size also needs to be limited. For example, within each cycle, the screw speed of the extruder can be adjusted to 0.9 times the screw speed of the previous cycle. To ensure stable coordination between the transmission equipment and the extruder, the linkage linear speed of the transmission equipment needs to be reduced simultaneously. In specific calculations, the adjusted third screw speed can be substituted into the first linear relationship to obtain the third extruded rubber volume. Since the premise of the adjustment is that the quality of the target rubber product produced is qualified, the first processing weight per meter of the processing equipment should remain basically unchanged. At this time, the ratio of the third extruded rubber volume to the first processing weight per meter can be used as the new third linkage linear speed of the transmission equipment. It should be noted that the initial first screw speed is used as the reference value of the screw speed of the extruder. If the calculated third screw speed is already less than the first screw speed, the first adjustment mode is exited, and the screw speed of the extruder and the linkage linear speed of the transmission equipment are no longer adjusted.

[0058] When the absolute difference between the width of the second product and the width of the first product is greater than the first preset threshold, it indicates that the width error of the target rubber product has exceeded the acceptable range, that is, the quality of the target rubber product is unqualified. At this time, priority should be given to ensuring the quality of the target rubber product.

[0059] Optionally, in the second adjustment mode, the screw speed of the extruder can be kept constant, while the linear speed of the conveyor can be adjusted accordingly. For example, if the width of the second part of the target rubber product is too large, it indicates that there may be too much rubber material input into the processing equipment. In this case, the linear speed of the conveyor can be appropriately reduced until the width of the second part meets the quality requirements. Conversely, if the width of the second part of the target rubber product is too small, it indicates that there may be too little rubber material input into the processing equipment. In this case, the linear speed of the conveyor can be appropriately increased until the width of the second part meets the quality requirements.

[0060] In this embodiment, by collecting relevant data from the production process of various specifications of rubber products and performing linear fitting, a linear relationship can be obtained between the screw speed and rubber output of a multi-specification universal extrusion extruder, as well as a linear relationship between the extrusion width of the extrusion extruder and the width of the rubber product processed by the processing equipment. Subsequently, during the production of rubber products, it is only necessary to substitute the parameters of the rubber product to be produced and the pre-configured parameters of the transmission equipment and processing equipment into the above linear relationship to obtain the working parameters to be set for the extrusion extruder, including the screw speed and extrusion width. During the production process, the screw speed of the extrusion extruder and the linkage linear speed of the transmission equipment can be automatically adjusted according to the actual production status, while ensuring the quality of the rubber products. The entire production process is automated and requires no manual intervention, which can greatly improve the production efficiency of rubber products. In other words, this solution effectively solves the technical problem that the working parameters of the extrusion extruder need to be manually adjusted during the production of rubber products, resulting in low efficiency and difficulty in ensuring product quality.

[0061] Example 2

[0062] According to an embodiment of this application, a control device for an extrusion extruder for implementing the control method of the extrusion extruder in Embodiment 1 is also provided, such as... Figure 4 As shown, the control device of the extrusion extruder includes at least: an acquisition module 41, a determination module 42, a first calculation module 43, a second calculation module 44, and a control module 45, wherein:

[0063] The acquisition module 41 is used to acquire the first linkage linear speed preset by the transmission device, the first processing weight per meter preset by the processing equipment, and the first product width preset by the target rubber product when producing the target rubber product. The transmission device is used to transmit the rubber material extruded by the extruder to the processing equipment for processing to obtain the rubber product.

[0064] The determination module 42 is used to determine the first extruded amount of rubber per unit time of the extrusion extruder based on the first linkage linear speed and the first processing weight per meter;

[0065] The first calculation module 43 is used to substitute the first extruded amount of rubber into the first linear relationship between the screw speed and the extruded amount of rubber in the pre-configured extrusion extruder to obtain the first screw speed of the extrusion extruder;

[0066] The second calculation module 44 is used to substitute the width of the first product into the second linear relationship between the extrusion width of the pre-configured extrusion extruder and the width of the rubber product processed by the processing equipment to obtain the first extrusion width of the extrusion extruder.

[0067] The control module 45 is used to control the extrusion extruder to perform rubber extrusion based on the first screw speed and the first extrusion width.

[0068] The following section explains the functions of each module of the control device of the extrusion extruder in conjunction with the specific implementation process.

[0069] As an optional implementation, determining the first linear relationship between the screw speed of the extruder and the amount of rubber extruded can be achieved as follows: Multiple sets of first production record data corresponding to various specifications of rubber products are obtained, wherein each set of first production record data includes: the screw speed of the extruder and the amount of rubber extruded per unit time when producing a rubber product of a certain specification; the amount of rubber extruded per unit time is used as the independent variable and the screw speed as the dependent variable, and a linear fit is performed on the multiple sets of first production record data to obtain the first linear relationship.

[0070] Optionally, when determining the second linear relationship between the extrusion width of the extruder and the width of the rubber product processed by the processing equipment, it can be achieved as follows: obtain multiple sets of second production record data corresponding to rubber products of various specifications with qualified widths, wherein the rubber product with qualified width is the rubber product whose width after processing by the processing equipment is the same as the preset product width, and each set of second production record data includes: the extrusion width of the extruder and the width of the rubber product processed by the processing equipment when producing a rubber product of a certain specification with qualified width; with the rubber product width as the independent variable and the extrusion width as the dependent variable, perform linear fitting on the multiple sets of second production record data to obtain the second linear relationship.

[0071] As an optional implementation, when producing a target rubber product of a target specification, the acquisition module can obtain the first linkage linear speed pre-configured for the transmission equipment and the first processing weight per meter pre-configured for the processing equipment that matches the target specification from the relevant construction configuration table in the MES. At the same time, it determines the first product width of the target rubber product specified by the target specification.

[0072] Considering that the rubber extruded by the extruder is mainly transported by the conveying equipment and processed by the processing equipment to perform operations such as forced shrinkage, water cooling, and winding to obtain rubber products, the loss in the whole process is small. Based on the law of conservation of mass, the determining module can use the product of the first linkage linear velocity and the first processing meter weight as the first extruded rubber amount of the extruder per unit time. Then, the first calculation module substitutes the first extruded rubber amount into the above-mentioned first linear relationship to obtain the first screw speed of the extruder.

[0073] Meanwhile, the second calculation module can directly substitute the width of the first product into the second linear relationship mentioned above to obtain the first extrusion width of the extruder.

[0074] Subsequently, the control module can control the extruder to perform rubber extrusion based on the first screw speed and the first extrusion width.

[0075] In order to ensure that the quality of the produced rubber products can be strictly controlled during the production stage, while maximizing production efficiency and avoiding resource waste, this application embodiment further provides an automated adjustment mechanism for the screw speed of the extrusion extruder and the linkage linear speed of the transmission equipment.

[0076] As an optional implementation, the control device of the extrusion extruder in this application embodiment further includes an adjustment module for periodically acquiring the raw material state and product state of the target rubber product, and adjusting the screw speed of the extrusion extruder and the linkage linear speed of the transmission equipment based on the raw material state and product state.

[0077] Optionally, when the adjustment module adjusts the screw speed of the extruder and the linkage linear speed of the transmission device based on the raw material state and the product state, it can achieve the following: When the absolute difference between the second product width and the first product width is not greater than a first preset threshold, it enters a first adjustment mode, wherein in the first adjustment mode, the screw speed of the extruder and the linkage linear speed of the transmission device are increased or decreased based on a preset step size; when the absolute difference between the second product width and the first product width is greater than the first preset threshold, it enters a second adjustment mode, wherein in the second adjustment mode, the screw speed of the extruder remains constant, while the linkage linear speed of the transmission device is increased or decreased.

[0078] In the first adjustment mode, when the remaining raw material is not less than the second preset threshold, a first preset multiple of the screw speed of the extruder in the previous cycle is determined as the second screw speed. The second screw speed is substituted into the first linear relationship to obtain the second extruded amount of rubber from the extruder. Based on the second extruded amount of rubber and the first processed weight per meter, the second linkage linear speed of the transmission equipment is determined, wherein the first preset multiple is greater than 1. When the second screw speed is not greater than the preset upper limit of screw speed, the screw speed of the extruder is adjusted to the second screw speed, and the linkage linear speed of the transmission equipment is adjusted to the second linkage linear speed. When the second screw speed is greater than the preset upper limit of screw speed, the screw speed of the extruder and the linkage linear speed of the transmission equipment are not adjusted.
