[0066] Reference Figure 2 The controlling preparation equipment to process the raw materials according to the preparation process to obtain the PVC cable material required for the order specifically includes the following steps:

[0067] A1. Raw material pretreatment: According to the process control instructions, control the pretreatment equipment to pretreat various raw materials according to the process flow to obtain qualified raw materials required for the target formula;

[0068] A2. Raw material weighing: According to the process control instructions, weigh various qualified raw materials and send them into the high-speed mixer;

[0069] A3. Raw material mixing: According to the process control instructions, the high-speed mixer is controlled to mix and react various raw materials at a specified temperature and time to obtain fully mixed raw materials;

[0070] A4. Heating extrusion: According to the process control instructions, the mixed material is fed into the extruder, the extruder is controlled to heat and soften the mixed raw material at a specified temperature, and the material strip is extruded at a specified speed;

[0071] A5. Pelletizing and cooling: According to the process control instructions, control the cooling equipment to cool the material strip to the specified temperature, and then control the cutting machine to cut the cooled material strip into small particles of specified specifications to obtain the PVC cable material required for the order.

Finally, according to the process control instructions, send the raw materials to the optimized preparation equipment in sequence to realize the automatic production of PVC cable materials, finely control the cable material preparation process, improve production efficiency and save manpower, and effectively improve the production efficiency and quality of cable materials and reduce production costs.

[0072] Reference Figure 3 , the step of determining the target formula required according to the preparation requirements specifically includes the following steps:

[0073] B1. Matching the preliminary formula: According to the preparation requirements, at least one preliminary formula that meets the performance requirements is determined by matching a preset formula matching model; the formula matching model is a machine learning model obtained by training historical data; the preliminary formula includes at least one raw material information, at least one preparation equipment, preparation process information, equipment parameter information, expected yield and formula characteristics, and the formula characteristics include raw material characteristics and process characteristics;

[0074] B2. Optimize and iterate to generate candidate recipes: The recipe matching model optimizes and iterates each primary recipe in turn to generate corresponding candidate recipes;

[0075] B3. Calculate the formula score of each candidate formula: Calculate the formula score of each candidate formula by using a preset formula score formula for the iteratively generated candidate formula;

[0076] B4. Select the alternative formula with the highest formula score as the target formula. It should be noted that the specific training steps of the machine learning model are existing technologies and will not be repeated here. Through the above steps, the preliminary formula that meets the requirements is first determined by matching the formula matching model, and then the raw material characteristics and process characteristics of each preliminary formula are identified to iteratively optimize each preliminary formula to obtain the alternative formula. Finally, the optimized and iterative alternative formula is scored from three aspects: production profit, production efficiency and product performance, and then the alternative formula with low production cost, high production efficiency and good product quality is selected as the target formula, so as to effectively improve the production efficiency and quality of cable materials and reduce production costs.

[0077] In the production process of PVC cable materials, replacing some parts of the equipment according to the formula differences can improve production efficiency and production quality. For example, when facing a high-filling formula (such as adding a large amount of fillers such as calcium carbonate), the screw of the extrusion equipment can be replaced by a bimetallic screw made of alloy material. In the production of high-filling formulas, it can better cope with the wear of fillers, maintain a stable extrusion volume and plasticizing effect, reduce impurities in the product caused by screw wear, and improve product quality. At the same time, due to the reduction of equipment maintenance and screw replacement time, production efficiency is also improved. When facing a formula with strict temperature control requirements for a certain process step (such as containing temperature-sensitive additives), it is possible to consider replacing the control elements of the heating and cooling system. During the production process, the temperature can be controlled more accurately to avoid the impact of temperature fluctuations on sensitive additives. For example, when facing a formula with sticky raw materials that is difficult to stir evenly (such as a complex formula with multiple additives and resins), it is possible to consider replacing the stirring blades of the high-speed mixer, such as replacing the traditional stirring blades with high-shear blades with serrated edges. During the mixing process, various additives and resins can be better broken up and dispersed so that they are fully mixed. For formulas containing multiple functional additives, uniform mixing can ensure that each particle has the same performance, improving the consistency and quality of the product. Therefore, for the preliminary formulas that meet the preparation requirements matched by the formula matching model, each preliminary formula is optimized and iterated in turn to generate the corresponding alternative formulas according to the actual equipment conditions of the enterprise.

[0078] Reference Figure 4 The recipe matching model optimizes and iterates each preliminary recipe in turn to generate a corresponding candidate recipe, specifically including the following steps:

[0079] C1. Obtain basic information of the preparation equipment in the primary selected recipe, wherein the basic information of the preparation equipment includes equipment parameter information, equipment number information and replaceable component information;

[0080] C2. Optimizing the preliminary selected formula to generate multiple optimized formulas: The formula matching model optimizes the preliminary selected formula to generate multiple optimized formulas based on the replaceable component information of the preparation equipment in the preliminary selected formula and the formula characteristics; the optimized formula includes at least one raw material information, at least one preparation equipment, preparation process information, equipment parameter information, expected yield and equipment optimization information;

[0081] C3. Calculate the actual efficiency improvement value of each optimized formula through the preset efficiency calculation formula;

[0082] C4. Select alternative formulas: Compare each optimized formula with the primary formula, and select the formula with the highest actual efficiency improvement value as the alternative formula. It should be noted that the actual efficiency improvement value of the primary formula is 0.

[0083] The above efficiency calculation formula is as follows:

[0084]

[0085] Among them, X ij The actual efficiency improvement value of the jth optimized formula of the i-th preliminary formula after equipment optimization compared with the preliminary formula; C i The production time required to complete the order for the i-th primary formula; Y ij The production time required to complete the order for the jth optimized recipe of the i-th preliminary recipe, A ij is the time required to replace and debug the components of the preparation equipment according to the equipment optimization information in the jth optimized formula of the i-th preliminary formula; B is the total amount of PVC cable material required for the order, D i is the single production output of the i-th primary formula, E i is the expected yield of the i-th primary selected formula, F i is the single production time of the i-th primary formula; d ij is the single production output of the jth optimized formula of the i-th preliminary formula, e ij is the expected yield of the jth optimized recipe of the i-th preliminary recipe, f ij The single production time of the jth optimized formula of the i-th preliminary formula. According to the actual situation of the company's preparation equipment, the replaceable parts of each preparation equipment are determined, and then each preliminary formula is optimized based on its raw material characteristics and process characteristics to generate multiple optimized formulas. Then, combined with the order demand and the time required for component replacement and debugging during equipment optimization, the actual efficiency improvement value of each optimized formula is calculated, and the formula with the greatest efficiency improvement is selected as the alternative formula for the preliminary formula, which helps to match the order with the best target formula, realize the organic combination of multiple raw materials and give full play to the performance advantages of various raw materials, so as to effectively improve the preparation efficiency and preparation quality of PVC cable materials.

[0086] Reference Figure 5 The above-mentioned step of calculating the formula score of each candidate formula by using a preset formula score formula for the iteratively generated candidate formula specifically includes the following steps:

[0087] D1. Calculate production costs: Connect to the raw material supply chain platform to calculate the production cost Q of each alternative formula;

[0088] D2. Obtaining the estimated production time: Obtain the estimated production time W of each formula, which is the sum of F and A or C;

[0089] When the alternative formula is still the initially matched primary formula, the estimated production time of the alternative formula is W = C;

[0090] D3. Conduct production simulation: Conduct production simulation for each candidate formula to obtain the cable material performance parameters of each candidate formula;

[0091] D4. Calculate the formula score of each alternative formula: Calculate the formula score of each alternative formula using a preset formula score formula based on the production cost Q, estimated production time W and cable material performance parameters of each alternative formula.

[0092] The formula for scoring the above recipe is as follows:
