The feeding scale is a new type of feeding lock equipment developed based on years of practical experience in the application of rotary feeding equipment, which addresses the defects of easy filling, easy jamming, large gaps, and high air leakage that occur during the use of existing vertical grinding feeding equipment. This equipment comes from a screw conveyor or a silo feeding device, and the relatively uniform material flow is fed into the material level hopper scale through the discharge chute. A stable material level is established in the hopper scale through the control unit, and air is locked through the stable material level. Material level control is achieved by detecting the amount of material in the hopper scale through a weighing module, controlling the speed of the Feeder operation, and stabilizing the material level within the set range of the silo. This ensures that there is no material overflow or air leakage in the empty silo. The control unit can set the upper and lower limits of the silo, and the lower limit bin is the material seal. When the material level reaches the lower limit, the dense air feeder stops running to ensure that the material seal is not lost. Once the material exceeds the lower limit, the dense air feeder immediately runs. The weighing feeder includes a raw material bin, a pneumatic butterfly valve, a hopper scale, and a screw feeding device. The lower part of the raw material bin is equipped with a pneumatic butterfly valve, which is connected to the feeding port of the hopper scale. The lower part of the hopper scale is equipped with a screw feeding device, and the lower part of the screw feeding device is equipped with a corrugated tube weighing module. The raw material bin is installed on a two-layer steel frame platform through a buffer spring and a support column. The raw material bin is equipped with a stirring blade inside, which is connected to the stirring motor. The lower part of the raw material bin is also equipped with a pneumatic vibrator. The lower part of the pneumatic butterfly valve is connected to the feeding port of the hopper scale through a rubber flexible pipe. The inner part of the hopper.

The weighing feeder includes an upper cover plate and a cone. The screw feeding device includes a spherical feeding body, a feeding cylinder, a dropping box, a feeding screw, a shaft distribution box, and a reduction motor. The feeding port of the hopper scale is set on the upper cover plate. The upper part of the cone is connected to the upper cover plate through a clamp, and the lower part of the cone is connected to the upper part of the spherical feeding body through a clamp. The lower part of the spherical feeding body is connected to the feeding cylinder through a clamp, and one end of the feeding cylinder is connected to the dropping box. The feeding screw is set inside the feeding cylinder and the spherical feeding body. The reduction motor is connected to the input shaft of the shaft distribution box through a reduction motor connecting sleeve. The two output shafts of the shaft distribution box are connected to one end of the feeding screw through a connecting sleeve, and the other end of the feeding screw extends into the. The spherical feeding body and shaft distribution box are installed on the bottom plate, and there are three corrugated tube Weighing modules below the bottom plate. The upper end of the corrugated tube weighing module is connected to the bottom plate, and the lower end of the corrugated tube weighing module is installed on the bracket through a cushion block. The feeding Electronic scale includes a Feeding machine, which is equipped with a weighing sensor. The weighing sensor includes a housing and a weighing module; There is a gravity transmission mechanism inside the shell, which includes a gravity transmission rod. The gravity transmission rod is equipped with a first deformation driving block and a second deformation driving block; One end of the first deformation driving block and the second deformation driving block are equipped with a weighing sensor, which includes a weighing module. The weighing module is equipped with an upper pressure block and a lower pressure block. The gravity transmission rod corresponds to the end of the adjacent weighing module and is equipped with a pressure block. The central area of the weighing module is equipped with symmetrically distributed tension arms, and vibration strings are arranged between the tension arms; Symmetrically distributed magnetic pole blocks are set on both sides of the vibrating string, and the vibrating string is connected to the input end of the microprocessor inside the housing.

The feeding scale adopts automated control to achieve automatic control and supervision of raw material feeding, weighing and measuring, vacuum feeding, dispersion and stirring processes. The dispersion time and cylinder number can be selected and adjusted on the computer according to production requirements. The opening and closing of motor equipment and the opening and closing of feeding valves during the process are all controlled by the computer. A feeding scale is a weighing device that intermittently feeds and continuously discharges materials. Due to the feeding control being carried out in the hopper, it can achieve high control accuracy. The discharge screw machine is controlled by the reduction rate of material weight in the hopper scale to achieve the purpose of quantitative feeding. When the material in the weighing hopper reaches the lower limit position, the discharge screw machine fixes the discharge amount according to the current speed, and controls the material in the silo to quickly drop into the hopper scale. When the loading reaches the upper limit of weighing, it stops loading. Rapid loading can shorten the feeding time, improve the accuracy and control accuracy of weighing. The weighing feeder operates by gravity through a horizontally sealed filtering chamber door, and loose materials are directly fed to the rotor (rotor blades). The rotor selects the loose materials from the storage, transports them by gravity, measures them directly, and sends them into the wind conveying pipeline with the help of the wind power of the fan. The center of gravity is located on the axis through the flexible nodes between the precision material selection, wind pipeline, and rotor. Any reaction caused by pressure fluctuations can be fully compensated, and the measurement feeding results are not affected. Any material mass that appears at any time can be measured by the measuring device on the measuring section. The weight and position parameters of the material are stored in the Weighing system of the electronic scale. Before unloading the material, the parameters of the local load at each location can be known. The angular velocity required for unloading should be calculated in advance to adapt to the given value and the weight of the material stored in the storage.
