Description

Technical Field

[0001] This utility model belongs to the technical field of intelligent processing equipment for composite materials, specifically relating to a quantitative packaging device for carbon fiber reinforced PP composite materials. Background Technology

[0002] Carbon fiber reinforced polypropylene (PP) composites are composite materials with polypropylene (PP) as the matrix and carbon fiber as the reinforcement. The high strength and high modulus of carbon fiber endow the material with excellent mechanical properties, while PP provides good processability and chemical resistance. The combination of these two components makes it a promising candidate for applications in the automotive, electronics, and other fields.

[0003] The production of carbon fiber reinforced PP composite materials requires the use of conical container packaging devices. However, existing conical container packaging devices lack precise metering and control structures, leading to excessive quantitative errors. Material density is easily affected by temperature, humidity, and fiber distribution; manual judgment cannot meet the demands of high-precision production, severely impacting product quality and consistency.

[0004] This invention attempts to solve or at least alleviate the problem of excessive quantitative error during packaging by providing a quantitative packaging device for carbon fiber reinforced PP composite materials. Utility Model Content

[0005] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a quantitative packaging device for carbon fiber reinforced PP composite material, which has the advantage of being able to accurately package in quantitative quantities.

[0006] To achieve the above objectives, this utility model provides a quantitative packaging device, including a conical container body, a support frame, and a control cabinet, wherein the bottom of the support frame has multiple support legs;

[0007] The support frame is equipped with a pressure weighing sensor to sense weight, and also has a signal amplification and A / D conversion module to transmit pressure signals;

[0008] The conical container body has a discharge port on its side, an electric flow regulating valve is installed at the discharge port, and a conical guide sleeve is provided at the end of the discharge port;

[0009] The control cabinet has a built-in control unit that is electrically connected to the operation panel. The control unit communicates with the signal amplification and A / D conversion module and the electric flow regulating valve.

[0010] As a further improvement of this utility model, the pressure weighing sensor is integrated into the bottom of the support leg to sense the weight change of the material inside the conical container body in real time.

[0011] As a further improvement of this utility model, the signal amplification and A / D conversion module is fixed to the top or side wall of the support leg and directly connected to the output end of the pressure weighing sensor.

[0012] As a further improvement of this utility model, the conical guide sleeve is nested at the end of the discharge port, and its conical angle structure is used to homogenize the material flow rate.

[0013] As a further improvement of this utility model, the control unit in the control cabinet is configured to execute a phased feeding logic: when the real-time weight is lower than the target preset threshold, the electric flow regulating valve is instructed to be fully opened for coarse feeding; when the real-time weight reaches the target preset threshold, the opening of the electric flow regulating valve is dynamically adjusted for fine feeding.

[0014] As a further improvement of this utility model, the preset ratio target value is 85%-95%.

[0015] As a further improvement of this utility model, the operation panel integrates a data storage module for recording packaging time, target weight, and actual weight.

[0016] As a further improvement of this utility model, the support frame is welded and fixed to the conical container body to form an integral load-bearing structure.

[0017] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0018] This invention utilizes a pressure weighing sensor integrated at the bottom of the support leg to perceive material weight changes in real time. Combined with efficient signal amplification and A / D conversion modules, it significantly improves weighing accuracy and response speed. The electric flow regulating valve, under phased commands from the control unit, first achieves high-speed "coarse" flow at full open, then dynamically adjusts the opening for precise "fine" flow, significantly reducing quantitative errors. The conical guide sleeve optimizes the uniformity of material flow at the outlet, effectively reducing residue and blockage of carbon fiber reinforced PP composite materials. The coordinated operation of the control cabinet and control panel enables fully automated control of the entire process, greatly reducing manual intervention and improving production efficiency. Data storage enhances quality traceability. Overall, it solves the shortcomings of traditional devices such as inaccurate metering, uncontrolled flow rate, and poor adaptability, and is particularly suitable for the precise packaging needs of materials with fluctuating carbon fiber content.

[0028] The support frame 2 is equipped with a pressure weighing sensor 22 for sensing weight, and also has a signal amplification and A / D conversion module 23 for transmitting pressure signals;

[0029] The conical container body 1 has a discharge port 11 on its side, an electric flow regulating valve 12 is installed on the discharge port 11, and a conical guide sleeve 111 is provided at the end of the discharge port 11;

[0030] The control cabinet 3 has a built-in control unit and is electrically connected to the operation panel 31. The control unit communicates with the signal amplification and A / D conversion module 23 and the electric flow regulating valve 12.

[0031] As a preferred embodiment of this utility model, the pressure weighing sensor 22 is integrated into the bottom of the support leg 21 and is used to sense the weight change of the material inside the conical container body 1 in real time.

[0032] As a preferred embodiment of this utility model, the signal amplification and A / D conversion module 23 is fixed to the top or side wall of the support leg 21 and directly connected to the output end of the pressure weighing sensor 22.

[0033] In a preferred embodiment of this utility model, the conical guide sleeve 111 is nested at the end of the outlet 11, and its conical angle structure is used to homogenize the material flow rate. The conical guide sleeve (111) has a conical angle of 30°-45° and a polished surface.

[0034] As a preferred embodiment of this utility model, the control unit in the control cabinet 3 is configured to execute a phased feeding logic: when the real-time weight is lower than the target preset threshold, the electric flow regulating valve 12 is instructed to be fully opened for coarse feeding; when the real-time weight reaches the target preset threshold, the opening degree of the electric flow regulating valve 12 is dynamically adjusted for fine feeding.

[0035] As a preferred embodiment of this utility model, the preset ratio target value is 85%-95%.

[0036] As a preferred embodiment of this utility model, the operation panel 31 integrates a data storage module for recording packaging time, target weight, and actual weight.

[0037] As a preferred embodiment of this utility model, the support frame 2 is welded and fixed to the conical container body 1 to form an integral load-bearing structure.

[0038] Working Principle: A support frame 2 is provided on the outer side of the conical container body 1, providing support for the conical container body 1. The support frame 2 has multiple support legs 21 at its bottom, used to stably position the conical container body 1 on the ground. Pressure weighing sensors 22 are installed at the bottom of the support legs 21, capable of weighing and sensing pressure changes on the upper support legs 21. A signal amplification and A / D conversion module 23 is installed at the top of the pressure weighing sensor 22 for processing and transmitting the pressure signal. A discharge port 11 is provided on the side of the conical container body 1, and an electric flow regulating valve 12 is installed on the discharge port 11. The electric flow regulating valve 12 controls the flow rate of the material in the discharge port 11. A conical guide sleeve 111 is provided at the end of the discharge port 11, ensuring a stable and uniform flow of material. A control cabinet 3 is located on the side of the conical container body 1, containing a control unit. An operation panel 31 is located on the top of the control cabinet 3. The control unit is electrically connected to the operation panel 31, the signal amplification and A / D conversion module 23, and the electric flow regulating valve 12, or at least their signals are interconnected.

[0039] After the material is loaded into the conical container body 1, its weight is detected in real time by the pressure weighing sensor 22 at the bottom. The generated signal is processed into a digital signal by the signal amplification and A / D conversion module 23 and transmitted to the control unit in the control cabinet 3. After the operator sets the target weight through the operation panel 31, the control unit starts phased control: when the real-time weight is lower than 85%-95% of the target value, the electric flow regulating valve 12 is fully opened to perform "coarse discharge"; when the real-time weight reaches 85%-95% of the target value, the control unit dynamically reduces the opening of the electric flow regulating valve 12 to enter the "fine discharge" mode; when the material flows through the conical guide sleeve 111, uniform discharge is achieved; when the real-time weight is equal to the target value, the control unit closes the electric flow regulating valve 12 and triggers the storage module to record data to the operation panel 31.

[0040] In summary, this invention utilizes a pressure weighing sensor integrated at the bottom of the support leg to perceive material weight changes in real time. Combined with the efficient processing of the signal amplification and A / D conversion module, it significantly improves weighing accuracy and response speed. The electric flow regulating valve, under the phased commands of the control unit, first achieves high-speed "coarse" flow in a fully open state, and then achieves precise "fine" flow through dynamic adjustment of the opening, significantly reducing quantitative errors. The conical guide sleeve optimizes the uniformity of material flow at the outlet, effectively reducing residue and blockage of carbon fiber reinforced PP composite materials. The collaboration between the control cabinet and the operation panel enables fully automated control of the entire process, greatly reducing manual intervention and improving production efficiency. The data storage function enhances quality traceability capabilities. Overall, it solves the shortcomings of traditional devices such as inaccurate metering, uncontrolled flow rate, and poor adaptability, and is particularly suitable for the precise packaging needs of materials with fluctuating carbon fiber content.
