Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, specifically to a fully automatic feeding and weighing system. Background Technology

[0002] Currently, the material feeding and weighing field generally relies on manual operation or semi-automatic equipment. Manual operation suffers from low efficiency and is prone to human error, resulting in poor weighing accuracy. Deviations in material proportions directly affect product quality stability. While semi-automatic equipment improves efficiency to some extent, it still depends on manual intervention for positioning and feeding control, and its weighing accuracy is insufficient to meet the high standards required by industries such as chemical, food, and pharmaceutical. Furthermore, existing equipment has revealed deficiencies in weighing consistency during long-term operation.

[0003] Another core flaw in existing technology lies in its unreasonable equipment structural design. Traditional equipment cannot adapt to material receiving containers of different heights, and the lifting mechanism lacks precise adjustment capabilities, resulting in poor versatility when handling materials of different specifications. Furthermore, the fixed structure makes it difficult to achieve dynamic height matching during the material receiving process, easily causing material deviation or weighing errors. Such equipment cannot achieve precise feeding of minute quantities of material and lacks real-time monitoring capabilities for material accumulation height, necessitating the development of an integrated system that combines high-precision weighing, automatic lifting, and real-time control functions.

[0040] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0041] In practical use, the fully automatic feeding and weighing system according to this utility model includes a high-precision weighing unit, a micro-feeding unit, a feeding unit fixing device, an automatic lifting unit, and an intelligent control unit.

[0042] High-precision weighing unit: It adopts a built-in electromagnetic balance, which is located below the material receiving area. It is used to measure the weight of the material in real time and can realize functions such as weighing, tare, and accumulation through the communication interface. It can also transmit the weighing data to the control unit in real time.

[0043] Micro-feeding unit: This unit consists of a micro-feeding device, a motor drive unit, and a relay transfer module.

[0044] Micro-feeding unit: Utilizing a two-stage feeding design, the power chamber is powered by a motor drive unit. Power is transmitted to a relay gear, which precisely distributes and transmits the power to the hopper agitator and the bottle-neck agitator. The bottle-neck agitator first initially agitates the powder in the sample bottle, breaking up any agglomerates and allowing it to smoothly pass through the bottle neck into the hopper. The hopper agitator then further refines and mixes the powder entering the hopper, ensuring uniform dispersion of different powder types. Simultaneously, a high-precision control system precisely adjusts the output power and speed of the servo motor, enabling precise control of the feeding speed and quantity. Positioning holes are designed at the bottom and rear of the feeding unit for secure fixing.

[0045] Motor drive unit: It adopts a high-precision stepper servo motor, which can control the feeding speed and weight by adjusting the speed.

[0046] Relay transfer module: It adopts a buckle design that is compatible with robotic arms, which facilitates the transfer of weighed materials to the reaction vessel and can be adapted to various container sizes.

[0047] Micro-feeding unit fixing device: There are four positioning pins under the fixed base. The micro-feeding unit is placed on the fixed base by the robotic arm. The positioning pins on the base and the positioning holes reserved in the feeding unit are used to fix it in the horizontal direction. The control system can use the laser sensor on the side of the fixed base to determine whether the feeding unit is in place. After fixing, the dual precision push rod motor at the rear pushes the two positioning pins into the positioning holes at the rear of the feeding unit to fix the feeding unit in the vertical direction.

[0048] Automatic lifting unit: The automatic lifting unit consists of linear guides and servo steppers, and can dynamically adjust the micro-feeding unit to the appropriate position according to the specifications of the relay transfer module. A laser sensor layout is incorporated into the structure: used to monitor the height and position information of the material in real time and transmit the monitoring data to the control system.

[0049] Intelligent control system: It is electrically connected to the feeding device, weighing device, automatic lifting device and laser sensor. It is used to receive data transmitted by the weighing device and laser sensor, and control the feeding speed and feeding amount of the feeding device and the lifting action of the automatic lifting device according to the preset weight parameters and material height requirements, so as to realize the precise control of the fully automatic feeding and weighing process.

[0050] The specific implementation method of the fully automatic material feeding and weighing system according to this utility model is as follows:

[0051] System installation and commissioning: Install the material storage device, feeding device, weighing device, automatic lifting device, and laser sensor according to the design requirements, and connect and commission them through the control system. Based on actual production needs, preset parameters such as the target weight of the material, feeding speed, and lifting height in the control system.

[0052] Material feeding and weighing: After the robotic arm places the micro-feeding unit onto the fixed base, a laser sensor detects the position signal, and a pusher motor pushes the fixing pin to secure the feeding unit. The laser sensor monitors the height of the relay transfer module in real time and adjusts the automatic lifting platform to the set position before starting the system. The control system controls the motor drive unit to move and drive the micro-feeding unit to begin feeding. The material falls into the relay transfer module through the feeding device. The system's built-in balance measures the material weight in real time and transmits the weight data to the control system.

[0053] Automatic control process: The control system compares the weight data transmitted by the built-in balance with the preset target weight. When the material weight approaches the target weight, the control system controls the micro-feeding mechanism to reduce the feeding speed for precise feeding until the target weight is reached, at which point feeding stops. Simultaneously, based on the height of the relay transfer module fed back by the laser sensor and combined with preset height requirements, the control system controls the drive mechanism of the automatic lifting device. This mechanism uses linear guides to raise and lower the support frame, adjusting the system height to ensure smooth material receiving and accurate weighing.

[0054] Repeated operation: After completing one feeding and weighing operation, the material receiving container can be changed and the system restarted according to production needs to perform the next fully automatic feeding and weighing operation.

[0055] In summary, the specific beneficial effects of the above-described technical solution of this utility model are as follows:

[0056] High-precision weighing: The built-in balance enables high-precision measurement of material weight, and the micro-feeding mechanism provides precise control of the feeding amount, significantly improving weighing accuracy and consistency and meeting the needs of the high-precision weighing industry.

[0057] Full-process automation: Based on the coordinated operation of the control system and various components, the system completes the fully automatic operation from material feeding and real-time weighing to height adjustment without human intervention, effectively improving production efficiency and reducing human error.

[0058] Strong versatility and adaptability: With the adjustable height design of the automatic lifting device and the precise lifting control of the linear guide rail, it can be adapted to material receiving containers of different heights and specifications, enhancing the equipment's versatility and adaptability to different scenarios.

[0059] Real-time precise control: The system uses laser sensors to monitor the height and position of materials in real time, and dynamically adjusts the feeding parameters based on the monitoring data to ensure the accuracy and stability of the weighing process.
