Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] like Figure 1 - Figure 7 As shown, the present application provides an automatic metering, feeding and stirring device 1 for plastic production, comprising:

[0035] At least two feeding mechanisms 10, each feeding mechanism 10 includes a feeding hopper 11 and a moving assembly 13 located above the feeding hopper 11, and a first valve 111 is provided at the feeding port of each feeding hopper 11 and a second valve 113 is provided at the discharging port;

[0036] A stirring mechanism 30 is provided below at least two feeding mechanisms 10 , wherein the feeding port of the stirring mechanism 30 is connected to the discharging ports of at least two feeding hoppers 11 , and the discharging port of the stirring mechanism 30 is provided with a third valve 31 ;

[0037] The granulator 50 is provided with a feed hopper 51. The granulator 50 is arranged below the stirring mechanism 30. The feed port of the feed hopper 51 is connected to the discharge port of the stirring mechanism 30.

[0038] The electric control mechanism is electrically connected to at least two feeding mechanisms 10 and the stirring mechanism 30 .

[0039] First, it includes at least two feeding mechanisms 10, each of which is composed of a feeding hopper 11 and a moving assembly 13. These feeding hoppers 11 are designed to accommodate a certain amount of raw materials, while the moving assembly 13 is responsible for controlling the release of the raw materials from the feeding hopper 11. To ensure the accurate delivery of raw materials, the feed port of each feeding hopper 11 is equipped with a first valve 111. These valves can accurately control the inflow of raw materials, thereby controlling the flow of raw materials from the bag into the feeding hopper 11. At the same time, the discharge port of each feeding hopper 11 is also equipped with a second valve 113. These valves are responsible for controlling the outflow of raw materials, ensuring that the raw materials can be accurately delivered to the next processing link when needed, thereby controlling the flow of raw materials from the feeding hopper 11 into the stirring mechanism 30.

[0040] Furthermore, the feeding system includes two independent feeding mechanisms 10, each equipped with a crane for lifting bags containing plastic pellets. A controller controls the opening and closing of valves in each feeding mechanism 10 to adjust the feeding volume for plastic pellets of varying viscosities. By adjusting controller parameters, precise control of the ratio of the two plastic pellets can be achieved, meeting various formulation requirements.

[0041] Secondly, the stirring mechanism 30 is a core component of the device. It is designed to be located below at least two feeding mechanisms 10 to receive raw materials from these mechanisms. The feeding port of the stirring mechanism 30 is connected to the discharge ports of at least two feeding hoppers 11, ensuring a continuous supply of raw materials. To further ensure the uniformity and quality of the stirring process, the discharge port of the stirring mechanism 30 is equipped with a third valve 31. This valve controls the outflow rate and amount of the stirred material, ensuring that the material reaches the ideal mixing state before entering the feed hopper 51 of the granulator 50.

[0042] Furthermore, the discharge ports of the two feeding mechanisms 10 are directly connected to a closed mixing barrel 33. An operation panel is provided on one side of the mixing barrel 33 for controlling the valve opening and closing of each feeding mechanism 10. The mixing barrel 33 is equipped with multiple rotating stirring rods, which can be driven by a motor to fully mix the plastic particles entering the barrel to ensure the uniformity of the raw materials.

[0043] Next, the granulator 50 is another key component of the apparatus. It features a dedicated feed hopper 51 for receiving material processed by the mixing mechanism 30. The granulator 50 is positioned below the mixing mechanism 30, with the feed inlet of its feed hopper 51 connected to the discharge outlet of the mixing mechanism 30. This ensures a continuous supply of material, thus maintaining a continuous and efficient production process.

[0044] Furthermore, the bottom of the mixing barrel 33 is connected to the granulator 50 through a pipe. After the mixing is completed, the valve at the bottom of the mixing barrel 33 is opened, and the material can flow into the granulator 50 for further processing into granular products. This process is also managed by the control system to ensure the continuity and stability of the entire process.

[0045] Finally, the electronic control mechanism is the control center of the entire device. It is electrically connected to at least two unloading mechanisms 10 and the stirring mechanism 30, responsible for the automated control of the entire device. Based on pre-set programs and parameters, the electronic control mechanism precisely controls the opening and closing of each valve and the movement of the moving assembly 13, thereby achieving automation and intelligent control of the entire production process.

[0046] Structural layout: In order to optimize space utilization and ensure operational safety, the present invention designs the three links of feeding, stirring and granulating into a vertically distributed three-level structure. Each layer is independent of each other but closely connected, which is convenient for maintenance and overhaul and conducive to the realization of full-process automated control.

[0047] Furthermore, at least two feeding mechanisms 10, a stirring mechanism 30 and a granulator 50 are vertically distributed to form a three-level structure.

[0048] At least two feeding mechanisms 10, a stirring mechanism 30, and a granulator 50 are configured. These mechanisms are arranged vertically, forming a three-level structure. In this layout, the mechanisms on each level are independent of each other. This design not only helps optimize space efficiency but also ensures safety during operation.

[0049] Furthermore, a control panel is provided on one side of the stirring mechanism 30 , and the control panel is electrically connected to at least two first valves 111 , at least two second valves 113 and the third valve 31 .

[0050] A control panel is specially designed and installed on one side of the stirring mechanism 30. This control panel is interconnected with at least two first valves 111, at least two second valves 113, and a third valve 31 through electrical connections. These valves are precisely controlled and managed to ensure that the flow and mixing of materials during the stirring process can be carried out in accordance with established procedures and requirements. The control panel may be equipped with various indicator lights, buttons, and display screens, allowing the operator to easily monitor and adjust various parameters during the stirring process, thereby ensuring the quality and efficiency of the stirring. Through such a design, the stirring mechanism 30 can achieve independent control of different valves to adapt to the needs of different materials and process flows, ensuring the flexibility and reliability of the entire stirring process.

[0051] Furthermore, the moving component 13 is a crane.

[0052] Mobile components 13 refer to mechanical devices that can be mounted on various devices to perform specific functions. Among the numerous mobile components 13, cranes are a very important type of equipment, primarily used to lift and move heavy objects. The use of cranes can significantly improve work efficiency, reduce manpower requirements, and provide greater safety and precision when handling heavy cargo. There are many types of cranes, including but not limited to tower cranes, crawler cranes, truck cranes, and fixed cranes. Each type of crane has its own unique design and scope of application to meet different operational needs.

[0053] Furthermore, the unloading mechanism 10 further includes a frame 15 , the unloading hopper 11 is connected to the bottom of the frame 15 , and the crane is connected to the top of the frame 15 .

[0054] The frame 15 not only provides a stable support base for the entire unloading mechanism 10 but also ensures the stability and durability of the entire system. The design of the frame 15 takes into account load-bearing capacity and stability to accommodate the unloading requirements of materials of varying weights and volumes. The unloading hopper 11, a key component of the unloading mechanism 10, is meticulously designed and connected to the bottom of the frame 15. This layout enables the unloading hopper 11 to efficiently receive and process materials, ensuring smooth discharge from the system. Furthermore, the crane connected to the top of the frame 15 is another indispensable component. The addition of the crane greatly enhances the flexibility and operational range of the unloading mechanism 10, making the handling of large or heavy materials a breeze. Through the precise control of the crane, operators can easily place materials in the designated location, thereby improving the efficiency and safety of the entire unloading process. In summary, the frame 15, the unloading hopper 11, and the crane work together to form a fully functional and easy-to-operate unloading mechanism 10, providing strong support for various industrial production processes.

[0055] Furthermore, each lower hopper 11 is provided with a material sensor and a temperature sensor, and both the material sensor and the temperature sensor are electrically connected to the electric control mechanism.

[0056] Material sensors and temperature sensors are specially installed inside each hopper, and these sensors are electrically connected to the electronic control mechanism through wires.

[0057] The electronic control mechanism is responsible for real-time monitoring and regulating the state of the material in the discharge hopper 11, ensuring that the material temperature and flow rate remain within the optimal operating range. Through precise control, the electronic control mechanism can automatically adjust the material discharge speed and stirring intensity, thereby ensuring uniform mixing and stable quality of the materials. In addition, the electronic control mechanism also has a fault diagnosis function. If an abnormality is detected, it will immediately issue an alarm and take appropriate protective measures to avoid potential accidents during the production process.

[0058] To further enhance production efficiency and ease of operation, the automatic metering and mixing device features an advanced user interface. Operators can easily set production parameters such as temperature, mixing speed, and feed rate via the touchscreen. This intuitive interface allows operators to quickly master the device, reducing training time and the potential for operational errors.

[0059] The device also excels in safety. In addition to the protective functions of the electronic control mechanism, the entire device is also equipped with an emergency stop button and a safety shield. In any emergency, the operator can quickly press the stop button to immediately cut off the power supply and prevent accidents. The safety shield ensures that the operator stays away from the danger zone during operation, ensuring personal safety.

[0060] In summary, this automatic metering, feeding, and stirring device for plastics production, through its innovative design and advanced technology, not only improves production efficiency and product quality, but also ensures safe and convenient operation. It is suitable for plastics production of all sizes, meeting the diverse needs of different customers, and is an indispensable and efficient device in the modern plastics processing industry.

[0061] Furthermore, the stirring mechanism 30 includes a stirring barrel 33 , a stirring rod and a motor. The stirring rod is disposed in the stirring barrel 33 , and the motor drives and connects the stirring rod.

[0062] The stirring mechanism 30 is mainly composed of three core components: a stirring barrel 33, a stirring rod and a motor. Among them, the stirring barrel 33 is a container for containing stirring materials. It usually has a certain volume and shape to facilitate the mixing and stirring of materials. The stirring rod is placed inside the stirring barrel 33. It is a long rod-shaped tool, one end of which is connected to the motor, and the other end extends into the inside of the stirring barrel 33, for directly contacting and stirring the materials. The motor serves as the power source of the stirring mechanism 30. Through its internal rotation mechanism, it converts electrical energy into mechanical energy, thereby driving the stirring rod to rotate. The motor and the stirring rod are connected by an appropriate transmission device to ensure that the rotational power of the motor can be effectively transmitted to the stirring rod, so that the stirring rod can mix and stir the materials in the barrel at a certain speed and force. The design and operation of the entire stirring mechanism 30 are aimed at achieving efficient mixing of various materials and are widely used in chemical, food, pharmaceutical and other industries.

[0063] Furthermore, the stirring rod is in a spiral or blade shape.

[0064] The design of the stirring rod usually adopts a spiral or paddle-shaped structure. This design enables the stirring rod to effectively push and mix liquids or solid particles during rotation, thereby achieving the purpose of uniform mixing. Due to its unique spiral shape, the spiral stirring rod can generate downward pressure during the stirring process, which helps to push the material to the bottom of the stirring container and thus improve the mixing efficiency. The paddle-shaped stirring rod usually has a larger surface area and can provide greater shear force, which is suitable for mixing processes that require strong shear. Different stirring rod shapes are suitable for different stirring needs and material characteristics. Therefore, when selecting a stirring rod, it is necessary to decide which shape to use based on the specific stirring task and the physical and chemical properties of the material.

[0065] Furthermore, a filter screen is provided at the bottom of the mixing barrel 33 .

[0066] A specially designed filter screen is installed at the bottom of the mixing drum 33 to effectively separate and filter out unwanted impurities and particulate matter during the mixing process. This filter screen ensures a higher level of purity for the stirred liquid or mixture, while also facilitating subsequent cleaning and maintenance. This design allows users to more conveniently process and recycle the contents of the mixing drum 33, improving the efficiency and quality of the entire mixing process.

[0067] Furthermore, the granulator 50 is also provided with a dust cover, which covers the outer periphery of the feed port of the feed hopper 51 .

[0068] The structural design of the granulator 50 specifically incorporates a dust cover, an important component. This dust cover is carefully designed to tightly cover the periphery of the feed port of the feed hopper 51. This design not only effectively prevents the leakage of dust and fine particles during the process of material entering the granulator 50, thereby protecting the cleanliness of the working environment, but also ensures the health and safety of the operators. In addition, the presence of the dust cover also helps to reduce the risk of contamination of the material during transportation, ensuring the purity of the material and the stability of the granulation process. Through this design, the performance of the granulator 50 has been further improved, and it also reflects the manufacturer's careful consideration of product quality and user needs.

[0069] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
