[0002] In the market, a melt flow rate meter is commonly used to measure the melt flow rate (MFR) value of various plastics and resins in the viscous flow state, so as to represent the physical properties such as fluidity and viscosity of polymer materials in the molten state; this method is widely used in industries such as plastic production, plastic products, petrochemical industry, polymer materials, as well as relevant colleges, universities, scientific research institutions and commodity inspection departments; by measuring the melt mass flow rate, enterprises can better understand the performance characteristics of plastic materials, so as to formulate more reasonable production processes and quality control standards.

[0003] At present, the measurement methods in the market are the mass method and the volume method. For different materials, when the melt index is less than 20, the mass method is used for testing, and when the melt index is greater than 20, the volume method is used for testing; however, most of the existing measuring instruments can only be tested by a single method and cannot be used in two ways, which affects the user experience and measurement cost.

[0004] In addition, for the current mass method test, a certain weight is placed on the tray, and at a certain temperature, the sample in the barrel is extruded, and it is cut every certain period of time. After calculation, the fluid rate is obtained. The existing equipment is all manually operated. Especially after the sample flows out, it is cut into sections every once in a while, and each section needs to be manually weighed and then input into the microprocessor respectively, and then operated step by step and finally printed out; the operation is very cumbersome, which affects the test efficiency and accuracy. Content of the Utility Model

[0005] The purpose of the utility model is to provide an intelligent melt flow rate meter capable of dual testing, which is proposed to solve the problems that most of the existing melt flow rate (MFR) value measuring instruments can only be tested by a single method and cannot be used in two ways, which affects the user experience and measurement cost, and the existing mass method test requires manual weighing and then inputting into the microprocessor one by one, with cumbersome operation and affecting the test efficiency and accuracy.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: an intelligent melt flow rate meter capable of dual testing, comprising:

[0007] A dual-purpose measuring instrument, on which a heating furnace is provided. The heating furnace includes a heating element and a material guiding cylinder. The material guiding cylinder is located inside the heating furnace and is used for loading and guiding a fixed volume of material. An encoder is provided at the end of the dual-purpose measuring instrument.

[0008] A suspended screen, which is rotatably connected to the side end of the dual-purpose measuring instrument, and a controller is arranged inside the suspended screen.

[0009] and a weighing module, the weighing module is connected to the bottom of the dual-purpose measuring instrument, and a sensor is arranged in the weighing module.

[0018] As a further description of the above technical solution:

[0019] The top of the material guiding cylinder extends to the heating furnace to form a feeding port.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are:

[0021] 1. In the present utility model, a heating furnace is provided on a dual-purpose measuring instrument. A material guiding cylinder is arranged inside the heating furnace. The material guiding cylinder is used to load and guide a fixed volume of materials. A feeding tool is used to put the materials into the feeding port. The heating element is responsible for heating the plastic raw materials in the material cylinder to a molten state to ensure the smooth flow of the materials. A material pressing tool is used to apply pressure to the materials. The material pressing tool moves downward inside the material guiding cylinder. The material pressing tool is connected to a rotating device, and an encoder is rotatably connected to the rotating device. The downward movement of the material pressing tool will drive the rotating tool to rotate, thereby driving the encoder to rotate. The rotation of the encoder generates a linear displacement and converts it into an electrical signal for output. This structure utilizes the cooperation of the material guiding cylinder and the encoder. For materials with a melt index greater than 20, a certain weight of materials can be selected and loaded into the material guiding cylinder, heated and melted, and then pressure is applied. The volume of the molten material flowing out of the test cylinder within a specified time is used to obtain the flow rate. For materials with a melt index less than 20, a certain weight of materials can be loaded into the material guiding cylinder, heated to melt, and then a certain pressure is applied at a certain temperature. The mass of the flowing molten material is weighed and measured. The melt mass flow rate is determined by calculating the mass of the molten material flowing out of the test cylinder within a specified time. This device realizes two measurement methods, namely volume method measurement and mass method measurement, and can be selected according to material requirements, greatly improving the user experience and reducing the measurement cost.

[0022] 2. In the present utility model, through the measurement of volume and mass, the density of the substance can also be obtained. The density can reflect the compactness and mass distribution of the material, enabling a more comprehensive understanding of the physical properties of the material, thereby more accurately evaluating its flow performance and other related properties. At the same time, it can also check the consistency of the material. If the density changes significantly, it may mean that the composition or state of the material has changed, which is of great significance for quality control and process optimization.

[0023] 3. In the present utility model, a sensor is arranged inside the weighing module, and a controller is arranged inside the suspended screen. The encoder, sensor, and controller are connected through a communication interface, forming an intelligent closed loop among the three. When the materials in the encoder are extruded within a certain time, they are placed on the weighing module for weighing. The encoder transmits the extrusion time signal to the controller, and the sensor on the weighing module transmits the weight signal to the controller. The controller can automatically calculate the melt flow rate through the existing data, optimizing the test process and improving the test efficiency and accuracy. Description of the Drawings

[0045] Working principle: By setting a heating furnace on the dual-purpose measuring instrument, a material guiding cylinder is arranged inside the heating furnace. The material guiding cylinder is used to load and guide a fixed volume of materials. The materials are put into the feeding port using a feeding tool. The heating element is responsible for heating the plastic raw materials in the cylinder to the molten state to ensure the smooth flow of the materials. A pressing tool is used to apply pressure to the materials. The pressing tool moves downward inside the material guiding cylinder. The pressing tool is connected to a rotating device, and the encoder is rotatably connected to the rotating device. The downward movement of the pressing tool will drive the rotating tool to rotate, thereby driving the encoder to rotate. The rotation of the encoder generates a linear displacement and converts it into an electrical signal for output. This structure utilizes the cooperation of the material guiding cylinder and the encoder. For materials with a melt index greater than 20, a certain weight of materials can be selected and loaded into the material guiding cylinder, heated and melted, and then pressure is applied. The volume of the molten material flowing out of the test cylinder within a specified time is used to obtain the flow rate. For materials with a melt index less than 20, a certain weight of materials can be loaded into the material guiding cylinder, heated to melt, and then a certain pressure is applied at a certain temperature. The mass of the flowing molten material is weighed and measured. The melt mass flow rate is determined by calculating the mass of the molten material flowing out of the test cylinder within a specified time. This device realizes two measurement methods: volume method measurement and mass method measurement, which can be selected according to material requirements, greatly improving the user experience and reducing the measurement cost. In addition, by setting a sensor in the weighing module and a controller in the suspended screen, the encoder, sensor, and controller are connected through a communication interface, forming an intelligent closed loop among the three. When the materials in the encoder are extruded within a certain time, they are placed on the weighing module for weighing. The encoder transmits the extrusion time signal to the controller, and the sensor on the weighing module transmits the weight signal to the controller. The controller can automatically calculate the melt flow rate through the existing data, optimizing the test process and improving the test efficiency and accuracy.
