[0071] The feeding module includes multiple independent feeding branches, each branch equipped with a distribution station, intelligent material selection valve, material cut-off valve and material identification sensor;
[0072] The material identification sensor includes a near-infrared spectrometer and a density detector, which are used to identify the type and physical properties of raw materials and are connected to the injection molding equipment control system to automatically set the injection molding parameters based on the raw material identification results.
[0073] Each branch in the feeding module is also equipped with:
[0074] Impurity removal unit: includes multi-stage filter screens and a washing and mixing tank, used for screening and density sorting of raw materials;
[0075] Drying unit: includes a dryer and a humidity sensor, used to dry the raw materials after impurity removal;
[0076] Weighing unit: Used to weigh the dried raw materials and adjust the feeding amount in conjunction with the AI optimization unit.
[0077] In the feeding module:
[0078] The distribution station is used to distribute the raw materials from the main feeding pipeline to each feeding branch as needed. It supports parallel switching of multiple raw materials. The distribution station combines the feedback from the material identification sensor to dynamically adjust the raw material distribution path and links with the dynamic scheduling control unit to optimize the raw material distribution priority according to the load status of the injection molding equipment. The data from the material identification sensor is fed back to the distribution station to ensure that the raw material type matches the parameters of the target injection molding equipment.
[0079] The material shut-off valve is located at the end of the feeding branch to control the flow of raw materials and prevent overfeeding. It uses double sealing gaskets and integrates a pressure sensor to monitor the valve's opening and closing status in real time.
[0080] High-pressure gas jet cleaning device is installed in the distribution station, the material shut-off valve and the material feeding branch. It automatically cleans the residue in the station, valve and material feeding branch after material change.
[0081] An optical detection device uses optical sensors to detect the cleaning effect of the high-pressure gas jet cleaning device and triggers a secondary cleaning procedure if the cleaning standard is not met.
[0082] The distribution station and the intercepting valve work together with the intelligent material selection valve to achieve rapid switching of raw materials from multiple branches. The intelligent material selection valve optimizes the distribution logic through the AI algorithm of the control module. Combined with the residual material recovery module, it simultaneously triggers the closing and cleaning procedures of the intercepting valve when switching raw materials, reducing downtime.
[0083] The feeding module employs adaptive adjustment technology for multiple independent feeding branches, including telescopic pipes and intelligent positioning devices, which support module expansion or replacement within a set time through standardized interfaces.
[0084] During the feeding process, the raw materials first enter the impurity removal unit, where multi-stage filter screens remove impurities of different particle sizes. The cleaning and mixing tank further removes impurities with abnormal density through density sorting to ensure the purity of the raw materials. Then, the raw materials enter the drying unit, where the dryer uses humidity sensors to precisely control the degree of drying and prevent the raw materials from being affected by moisture in subsequent processing.
[0085] The weighing unit weighs the dried raw materials and works in conjunction with the AI optimization unit to adjust the feeding amount based on real-time weighing data to achieve precise feeding.
[0086] This solves the problems of excessive raw material impurities, poor humidity control, and inaccurate material supply in existing technologies;
[0087] Compared with existing technologies, it improves the quality of raw materials, reduces product defects caused by impurities and moisture, and enhances product quality and production stability.
[0088] The system provides high-quality, quantitatively accurate raw materials for subsequent heating and injection molding processes, which is the foundation for ensuring the smooth operation of the entire production process.
[0089] The distribution station receives raw materials from the main feeding pipeline and, combined with the raw material information fed back by the material identification sensor and the load status of the injection molding equipment, dynamically adjusts the distribution path to allocate suitable raw materials to the corresponding feeding branches, thereby improving the efficiency and accuracy of raw material distribution.
[0090] The material shut-off valve is located at the end of the branch line. It uses double sealing gaskets to prevent raw material leakage and a pressure sensor to monitor the opening and closing status in real time, so as to accurately control the flow of raw materials and prevent overfeeding.
[0091] The high-pressure gas jet cleaning device automatically cleans up residues after material replacement, and the optical detection device detects the cleaning effect. If the cleaning standard is not met, a secondary cleaning is triggered to ensure the cleanliness of pipelines and equipment.
[0092] The intelligent material selection valve optimizes the allocation logic through AI algorithms, and when switching raw materials, it links the shut-off valve to close and the cleaning procedure to reduce downtime.
[0093] This solution addresses the problems of unreasonable raw material distribution, incomplete pipeline cleaning, and long downtime when equipment switches raw materials in existing technologies.
[0094] Compared with existing technologies, it improves production efficiency, reduces raw material waste and equipment failure rate. The system enables efficient switching and precise supply of raw materials from multiple branches, ensuring the continuity of production.
[0095] The heating module includes a heat-melting unit and a continuous heating unit:
[0096] The hot melt unit includes a hot melt box, which is used to heat and melt the weighed raw materials;
[0097] The continuous heating unit includes a pipe heating jacket and a temperature sensor. The pipe heating jacket adjusts the heating power through a PLC controller and dynamically maintains the temperature of the liquid raw material based on the detection results of the temperature sensor.
[0098] The inner wall of the pipe heating jacket is coated with an anti-stick coating, and the pipe diameter is adjustable, making it suitable for conveying high-viscosity or easily caking raw materials.
[0099] The non-stick coating is made of polytetrafluoroethylene;
[0100] After being weighed, the raw materials enter the hot melt box and are heated and melted in the hot melt unit, turning into liquid raw materials.
[0101] The heating jacket of the continuous heating unit is monitored by a temperature sensor and the heating power is adjusted by a PLC controller to dynamically maintain the temperature of the liquid raw material and ensure that it maintains appropriate fluidity during transportation.
[0102] The anti-stick coating on the inner wall of the pipe heating jacket prevents raw materials from adhering, and the adjustable pipe diameter can be adapted to high viscosity or easily caking raw materials.
[0103] This solves the problems of uneven heating of raw materials, difficulty in stable temperature control, and difficulty in conveying high-viscosity raw materials in existing technologies;
[0104] Compared with existing technologies, this technology ensures the quality stability of raw materials during heating and transportation, and reduces production failures caused by temperature fluctuations and raw material adhesion and agglomeration.
[0105] In the system, providing a stable liquid raw material to the injection molding module is a key link connecting the feeding module and the injection molding module.
[0106] The injection molding module includes:
[0107] The injection molding unit has its input end connected to the output end of the liquid raw material conveying pipeline, and is used to make plastic products from liquid raw materials.
[0108] The discharge unit includes a conveyor for transporting the finished product to the collection area;
[0109] The emergency material discharge unit automatically directs excess raw materials into a temporary storage bin when it detects excessive material feeding, thus avoiding machine shutdown and emptying.
[0110] After receiving liquid raw materials, the injection molding unit uses a specific process to mold them into plastic products, thus achieving product molding.
[0111] The conveyor in the discharge unit promptly transports the finished product to the collection area, ensuring the continuity of the production process;
[0112] When the emergency material discharge unit detects excessive material feeding, it quickly directs the excess material into a temporary storage bin to avoid shutdown and emptying operations caused by excessive material feeding.
[0113] This solution addresses the problems of unsmooth injection molding processes, untimely collection of finished products, and downtime caused by excessive material feeding in existing technologies.
[0114] Compared to existing technologies, it improves production efficiency, reduces equipment wear and tear and production interruptions. In the system, it is the core module for completing product production and is directly related to product quality and output.
[0115] Also includes:
[0116] The control module integrates AI algorithms to dynamically optimize the feeding amount, temperature and pressure parameters, and avoids overfeeding by feeding data through real-time weighing sensors. When the system changes materials, malfunctions or adjusts the process, it supports targeted removal of residual raw materials in specific pipes or modules.
[0117] The control module includes:
[0118] The AI optimization unit dynamically optimizes the material feeding rate, temperature, and pressure parameters. Based on real-time feedback data from the weighing sensor, it adjusts the material feeding strategy to avoid overfeeding. The AI optimization unit integrates a fault prediction and self-healing module. This module analyzes the operating parameters and environmental data of a specified injection molding equipment to predict potential faults and trigger at least one of the following operations:
[0119] Automatically switch to backup device;
[0120] Adjust the material feeding parameters to reduce the risk of failure;
[0121] Generate maintenance suggestions and push them to the user interface;
[0122] The AI optimization unit solves the problems of difficulty in accurately adjusting feeding parameters and the inability to prevent and handle equipment failures in advance in existing technologies.
[0123] Compared to existing technologies, it improves production reliability and equipment lifespan, reduces production costs, and is the core of achieving intelligent manufacturing within the system.
[0124] The targeted cleaning unit controls the residual material removal process in specific pipelines or modules during material change, malfunction, or process adjustment. The material removal process works in conjunction with the high-pressure gas jet cleaning device and the negative pressure adsorption device. The material removal process is linked with the residual material recovery module to remelt the cleaned old material and return it to the raw material silo.
[0125] The targeted removal unit solves the problem of improper handling of residual raw materials in the prior art, which can easily lead to raw material contamination and waste. Compared with the prior art, it reduces raw material waste, improves resource utilization, and ensures the stability of product quality. In the system, it maintains the cleanliness of the production system and ensures that different batches of products are not affected by residual raw materials.
[0126] The multi-module collaborative unit connects with the waste material recycling module, dynamic scheduling control unit, and life prediction unit to achieve data sharing and command coordination. The multi-module collaborative interface is linked with the dynamic scheduling control unit to dynamically adjust the material supply path and injection molding equipment task allocation according to the real-time status of the equipment and the priority of production tasks. The scheduling decision log and equipment health status are stored through the blockchain data recording unit.
[0127] The multi-module collaborative unit solves the problems of poor coordination between modules and unreasonable production scheduling in the existing technology. Compared with the existing technology, it improves the overall operating efficiency and traceability of the production system. In the system, resource allocation is optimized to ensure efficient production.
[0128] The real-time data acquisition unit acquires the operating parameters of the injection molding equipment, the status of raw materials, and the health information of the equipment through a sensor network, and transmits them to the AI optimization unit for dynamic optimization.
[0129] The real-time data acquisition unit solves the problems of opaque system operation status and inconvenient user operation in existing technologies. Compared with existing technologies, it improves the user experience, makes it easier for users to monitor and intervene in the production process, and establishes an interactive bridge between users and the system, making the production process more in line with actual needs.
[0130] The user interaction unit provides a visual interface to display real-time feeding parameters, equipment status, and fault warning information, and supports users to manually adjust optimization strategies or input production priority commands.
[0131] The waste material recovery module includes a negative pressure adsorption device, a melting and reprocessing unit, and a residual amount detection sensor. It is used to selectively remove residual raw materials in specific pipes or modules. The recovered waste material is melted and returned to the raw material silo, and the material traceability label is updated.
[0132] The workflow of the residual amount detection sensor begins with its deployment at key locations, including the outlet of the distribution station, the end of the feeding branch, the raw material inlet of the injection molding equipment, and the negative pressure adsorption port of the residual material recovery module, to ensure full coverage of the easily residual areas in the raw material flow path.
[0133] The sensor employs a multi-mode fusion technology combining weight sensors, optical sensors, and ultrasonic sensors. It monitors the weight of raw materials, reflected light intensity, or material height within the pipeline in real time, and calculates the residual amount by combining this with the pipeline's cross-sectional area. In complex scenarios such as those involving high-viscosity raw materials, it enhances reliability through dual-mode weight and optical detection. Data is acquired at a frequency of once per second and transmitted to the control module via an industrial bus, formatted into a standard data packet containing the sensor ID, timestamp, and residual amount value. Simultaneously, an edge computing preprocessing algorithm is used to filter vibration noise.
[0134] The dynamic threshold setting is based on the preset value of raw material type retrieved from the material matching database, and is dynamically optimized by combining AI algorithm with historical data. When the residual amount is detected to exceed the standard, the system immediately triggers the targeted cleaning procedure and records the fault code.
[0135] After cleaning, a second test is conducted to check the residual amount. If it meets the standard, the material traceability label is updated and new material supply is enabled. If it exceeds the standard three times in a row, the material supply path is locked and an alarm is pushed to the user interface.
[0136] Sensor data is further deeply integrated with AI algorithms to train the life prediction unit to predict pipeline blockage risks and dynamically adjust the detection interval and feeding strategy in frequent material change scenarios, prioritizing the clearing of paths corresponding to high-value orders.
[0137] In addition, the system performs zero-point calibration of the sensors daily. When the deviation exceeds 5%, a fault is marked and the system switches to a backup sensor. Meanwhile, the optical sensors are equipped with dust covers, the ultrasonic sensors have built-in temperature compensation modules, and high-temperature areas are encapsulated with high-temperature resistant ceramics to ensure environmental adaptability.
[0138] The waste material recycling module solves the problems of environmentally unfriendly waste material handling and chaotic material management in existing technologies.

[0141] The status recognition unit also includes pressure sensors and displacement sensors. The status recognition unit collects the operating parameters of the injection molding equipment in real time through multi-sensor fusion technology, including mold closing pressure and screw displacement parameters.
[0142] The multi-sensor fusion technology in the status recognition unit performs in-depth analysis and cross-validation of the data collected by each sensor, providing data support for the lifetime prediction unit and the dynamic scheduling control unit.
[0143] The life prediction unit is built based on deep learning algorithms. The input data covers multiple sources of information such as equipment operating parameters, environmental factors and historical maintenance records. Through continuous learning and training, it can accurately predict the remaining service life of key equipment components and formulate personalized maintenance plans.
[0144] The life prediction unit generates detailed maintenance recommendations based on the life prediction results of key components of different equipment, including maintenance time, maintenance content, and information on the parts that need to be replaced.
[0145] The dynamic scheduling control unit introduces a real-time order priority algorithm to determine the priority of production tasks based on factors such as order delivery time, product complexity, and customer importance.
