The four-head weighing device 5 is composed of a cylinder 5.1, a bracket 5.2, a connecting rod 5.3, and a hopper 5.4. The push plate machine 6 includes a push plate device 6.1, a conveyor belt 6.2, a push block mechanism 6.3, a fourth photoelectric sensor 6.4, an L-shaped guide trough 6.5, and a push plate The machine 6 is composed of a push plate device 6.1, a conveyor belt 6.2, a push and block mechanism 6.3, a fourth photoelectric sensor 6.4, and an L-shaped material guide trough 6.5. The roller weighing machine 9 includes a three-phase asynchronous motor 9.1, a roller 9.2, a second main frame 9.3, a support leg 9.4, and a clamping mechanism 9.5.

[0021] The raw material warehouse 1 adopts different structural forms according to actual conditions, such as sunken silo, bucket elevator, climbing belt conveyor, etc. The chain plate conveyor 2 is used to buffer and convey materials. It can smoothly switch the conveying direction and convey materials to both ends as needed. The rear guide trough 3 is fixed on the chain plate conveyor 2, and the front guide trough 4 is fixed on the chain plate conveyor 2. The four-head weighing device 5 is installed on the 30KG range weighing sensor 11, and the whole is fixed to the first main frame 10. The push plate machine 6 is installed on the second range 100KG weighing sensor 16, and the whole is fixed to the first main frame 10. The guide bin 7 is fixed on the first main frame 10, the telescopic guide cylinder 8 is fixed on the guide bin 7, and the roller weighing machine 9 is installed directly below the telescopic guide cylinder 8. The first photoelectric sensor 12, the second photoelectric sensor 13, the third photoelectric sensor 14, and the first range 100KG weighing sensor 15 are installed on the roller weighing machine 9;

[0022] The chain plate machine 2, the push plate machine 6, the guide bin 7 and other devices are installed on the first main frame 10. The overall structure is compact and convenient for inspection and troubleshooting. In the structural design, the frame adopts the square steel pipe welding form to improve the structural strength and rigidity. The executive components are screwed for easy disassembly and replacement. The chain plate machine 2 realizes feeding the push plate machine 6 and the four-head weighing device 5 respectively through the forward and reverse rotation of the motor, reducing the number of motors and improving cost performance. Positioning relies on photoelectric switches, and weighing relies on weighing sensors to improve motion control and weighing accuracy. According to the signals and data fed back by various sensors, the PLC analyzes and issues instructions to control the operation of the entire system. The four-head weighing device 5 uses four independent weighing units for weighing, and then processes and analyzes these data through the PLC to finally obtain accurate weight data.

[0023] The items to be weighed are placed on the scale pan, and four independent weighing units weigh them at the same time, and the data is transmitted to the PLC control system. After processing, accurate weight data is output, and the material barrel is replenished by controlling the actuator according to the analysis results of the weight data. This device has the characteristics of high efficiency, versatility, strong flexibility and high reliability. Finally, the amount of replenishment is controlled by the result of PLC analysis to accurately replenish the push mechanism 6.3 at the end of the push plate machine 6, so that the packaging accuracy is controlled within the weight range of one material. Since there is a certain impact and noise in the packaging process, the main structure design reserves a connection hole for installing the sound insulation board, which can be installed according to customer needs. In addition, voice recognition can be installed to enhance the user experience. Taking the above factors into consideration, the utility model has a compact structure, high cost performance, accurate weighing, scalability, and greatly improves the service life.

[0024] Working principle: The discharge of raw material bin 1 is controlled by PLC. First, the material is fed to the push plate machine 6 through the chain conveyor 2 and the rear guide trough 3. At the same time, the second range 100KG weighing sensor 16 measures the feeding weight and stops when it reaches the preset threshold. The barrel passes through the roller weighing machine 9. The feedback signal detected by the first photoelectric sensor 12, the second photoelectric sensor 13, and the third photoelectric sensor 14 is given to the PLC to control the roller weighing machine 9 to stop, so that the barrel reaches the bottom of the telescopic guide cylinder 8. Then the first range 100KG weighing sensor 15 measures the weight of the empty barrel. After the measurement is completed, the clamping mechanism 9.5 fixes the barrel body, and the telescopic guide cylinder 8 extends to the barrel mouth.

[0025] Next, the PLC controls the discharge of material from raw material silo 1. Hopper 5.4 of four-head weighing device 5 opens, and material is fed through chain conveyor 2, sequentially through front guide chute 4, four-head weighing device 5, guide silo 7, and telescopic guide cylinder 8. During the feeding process, a first-range 100kg load cell 15 measures the charge weight in real time. When the charge reaches value A (95%-98% of the package weight), raw material silo 1 stops discharging, chain conveyor 2 stops conveying, and hopper 5.4 of four-head weighing device 5 closes. After this, chain conveyor 2 resumes conveying the remaining material to hopper 5 of four-head weighing device 5. 4. After a delay of 5-10 seconds, the chain conveyor 2 stops transporting materials. After transporting materials, the 30KG range load cell 11 measures the weight B values ​​of the materials in the four hoppers (respectively B1, B2, B3, and B4). The PLC calculates the required packaging weight G value minus the A value Ga and performs a logical analysis and comparison with the B value. The one or more hoppers 5.4 closest to the result Ga are opened to refill the barrel. After refilling is completed, the first range 100KG load cell 15 measures the loading weight again to obtain the result Gb. Gb is divided by the weight of each piece of material Gn to obtain the required refill quantity N.

[0026] Finally, the push plate machine 6 is started. After the push and block mechanism 6.3 repeatedly acts in conjunction with the conveyor belt 6.2 and the photoelectric sensor 6.4, the material quantity N is added to the barrel through the L-shaped material guide trough 6.5. The above PLC performs motion control and logic analysis and calculation to achieve the purpose of accurate weighing and packaging. This system is suitable for packaging large particles with similar single particle weights, especially packaging conditions that require an accuracy of 1-2 material weight deviations.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.

It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
