The spiral feeding system has the advantages of shorter process flow, higher weighing accuracy, higher reliability, more flexible equipment layout, and significantly reduced plant height compared to traditional powder Weighing systems. According to the different positions of the weighing equipment in the powder vacuum Batching system, various addition scales and subtraction scales can be formed to meet the different requirements of customers. The vacuum weighing system consists of a feeding station or material storage bin, a vacuum Feeding machine weighing device, a PLC controller, and other components. It can complete the automatic feeding and batching of single material by weight or multiple materials with different formulas. Widely used in industries such as pharmaceuticals, food, chemicals, battery materials, building materials, metallurgy, and feed processing. Taking the application of powder vacuum weighing system in automatic weighing and batching of two types of materials as an example to illustrate the working principle of powder vacuum load-bearing system. Materials A and B are stored in two silos respectively. The powder vacuum weighing system starts working, the vacuum pump starts, and when the screw discharge valve A at the bottom of the powder silo of material A reaches a certain weight, the screw stops and the discharge valve A closes. The remaining material in the conveying pipe continues to be sucked into the weighing hopper. After suction, the weight of material A in the scale is exactly the set weight. At this time, the spiral discharge valve B at the bottom of material bin B is opened, and the spiral is started. Material B is sucked into the weighing hopper. When material B reaches a certain weight in the scale, the spiral stops and the discharge valve B is closed. The remaining material in the conveying pipe continues to be sucked into the weighing hopper. After suction, the weight of material B in the scale is exactly the set weight. The vacuum pump has stopped. The vacuum weighing system has the advantages of shorter process flow, higher weighing accuracy, higher reliability, highly flexible equipment layout, and significantly reduced plant height compared to traditional powder weighing systems. According to the different positions of the weighing device in the powder vacuum weighing system, various addition scales and subtraction scales can be formed to meet the different requirements of customers.

The weighing and feeding machine adopts a hopper scale, a mixing mechanism, a feeding device, and a spiral conveying mechanism. The hopper scale forms a longitudinally extending storage bin, and the bottom of the storage bin is equipped with a storage outlet. The mixing mechanism uses a rotating mixing part installed in the storage bin to mix and stir the materials in the storage bin. The feeding device forms a horizontally extending feeding bin, and one end of the feeding bin is equipped with a feeding inlet, which is set below the corresponding storage outlet. The other end of the feeding bin is equipped with a feeding outlet. The spiral conveying mechanism adopts a spiral conveying part installed in the feeding bin, wherein the mixing part is equipped with a scraping wall part to scrape off the materials on the inner wall of the storage bin, and the conveying part is equipped with a scraping wall part to scrape off the materials on the inner wall of the storage bin. Scraping off the material on the inner wall of the feeding bin can prevent sedimentation and blockage, and ensure more uniform feeding. The weighing hopper machine adopts a hopper, an arch breaker, a screw conveyor, a shell, and a discharge bin. An arch breaker is installed below the hopper, and a screw conveyor is installed below the arch breaker. The arch breaker and the screw conveyor are installed on the shell, and the end of the screw conveyor is equipped with a discharge bin. The front and rear sides of the hopper are respectively equipped with two legs, and each leg is equipped with a weighing module at the bottom. There is an air hammer on the left and right sides of the hopper, and each side is equipped with an air hammer, which can feed according to the required weight of the ingredients. The arch breaker can prevent powdery materials from solidifying, ensuring that the materials can be fully mixed. By adjusting the speed of the screw conveyor, the output speed of the materials can be adjusted. The feeding system inputs powdered materials into the funnel, and the weighing module below the four legs of the funnel will automatically display the weight of the input materials. The arch breaker will stir the materials to prevent them from clumping. After mixing, the materials enter the screw conveyor, and the spiral blades will move the animal materials when rotating. Adjusting the speed of the screw conveyor can adjust the output speed of the materials to control the mixing ratio. Finally, the materials flow out along the discharge port of the discharge bin and enter the next stage. The setting of the air hammer can be timed, and the air hammer will hit the hopper to prevent the materials from sticking to the surface of the hopper and causing material supply interruption, ensuring sufficient material supply.
