[0017] The present invention will be further described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] like Figure 1 As shown, a high-efficiency fully automatic dolomite flake weighing device includes an electrical control system 4, a conveying and feeding mechanism 5, a centrifugal turntable mechanism 3, a feeding and buffering mechanism 6, a high-precision weighing mechanism 2, and a servo material handling mechanism 1. The discharge end of the conveying and feeding mechanism 5 is connected to the feed end of the centrifugal turntable mechanism 3, and the discharge port of the centrifugal turntable mechanism 3 is connected to the feed end of the feeding and buffering mechanism 6. The discharge end of the feeding and buffering mechanism 6 is located directly above the weighing area of ​​the high-precision weighing mechanism 2. The working range of the servo material handling mechanism 1 covers the weighing area of ​​the high-precision weighing mechanism 2 and the area of ​​the preset material box 14. The electrical control system 4 is electrically connected to the conveying and feeding mechanism 5, the centrifugal turntable mechanism 3, the feeding and buffering mechanism 6, the high-precision weighing mechanism 2, and the servo material handling mechanism 1, and is used to control the various mechanisms to work together to complete the feeding, sorting, buffering, weighing, and screening of dolomite flakes.

[0019] The electrical control system 4 includes an electrical control cabinet 41, a touch panel 42, a power supply, and a PLC controller. The electrical control system 4 receives sensor detection signals, weighing data, and other signals through the PLC controller, and outputs commands to control the actions of each mechanism. The power supply provides power to each mechanism of the equipment. The PLC controller is electrically connected to the drive components of the conveying and feeding mechanism 5, the centrifugal turntable mechanism 3, the feeding buffer mechanism 6, the detection component of the high-precision weighing mechanism 2, and the drive component of the servo material handling mechanism 1. The touch panel 42 is communicatively connected to the PLC controller and is used to display equipment operating parameters. The electrical control system 4 also includes a fault alarm component, which includes a buzzer and a three-color warning light. When the equipment experiences material jamming, sensor malfunction, or motor overload, the buzzer activates and continuously sounds, and the three-color warning light emits a red light and flashes.

[0020] like Figure 2As shown, the conveying and feeding mechanism 5 is responsible for smoothly conveying the dolomite flakes to be processed from the initial position to the centrifugal turntable mechanism 3. It includes a support base 51, a conveyor belt 52, side plates 53, and a buffer plate 54. The support base 51 has a leveling adjuster at its bottom. The conveyor belt 52 is installed on top of the support base 51. The side plates 53 extend parallel to both sides of the conveyor belt 52, with their tops higher than the surface of the conveyor belt 52 to ensure that the dolomite flakes do not fall. The buffer plate 54 is inclined downwards between the discharge end of the conveyor belt 52 and the centrifugal turntable mechanism 3. Its top end connects to the discharge end of the conveyor belt 52, and its bottom end extends inwards towards the centrifugal turntable mechanism 3. The surface of the buffer plate 54 may have a rubber buffer layer to reduce impact on the dolomite flakes and ensure their integrity.

[0021] The centrifugal turntable mechanism 3 is used to disperse and organize the stacked dolomite flakes fed by the conveying and feeding mechanism 5 through centrifugal force, and then orderly guide them to the feeding buffer mechanism 6 through the spiral material channel 32, solving the problem of subsequent process jamming caused by material stacking. It includes a centrifugal turntable 33, an outer cover 31, a turntable drive device, a spiral material channel 32, and a centrifugal turntable outlet. The turntable drive device is mounted on the base box 34, and its output shaft is fixedly connected to the center of the centrifugal turntable 33, driving the centrifugal turntable to rotate horizontally. The outer cover 31 is located outside the centrifugal turntable and fixed to the base box 34. The spiral material channel 32 is provided inside the outer cover 31. The spiral material channel 32 extends upward at an angle of 5°-10° along the rotation direction of the centrifugal turntable 33, and its narrow size ensures that the dolomite flakes in the trough are in a single-layer queue. The centrifugal turntable 33 outlet is located at the end of the spiral material channel 32 and is connected to the inlet end of the feeding buffer mechanism 6.

[0022] The feeding and buffering mechanism 6 includes a buffer slide 61 and a second conveying module. The feed end of the buffer slide 61 is connected to the discharge port of the centrifugal turntable mechanism 3, and the buffer slide 61 extends downward at an incline. In its natural state, dolomite flakes in a single-layer queue enter the buffer slide 61 from the centrifugal turntable mechanism 3 and automatically slide towards the discharge end due to gravity. A full-load infrared sensor is installed in the buffer slide 61 near the feed end, and the infrared sensor is electrically connected to the electrical control system 4. Thus, the dolomite flakes remain in a single-layer queue at this time. Therefore, when the full-load infrared sensor near the feed end detects dolomite flakes, it indicates that the buffer slide 61 is about to be full, and the electrical control system 4 controls the conveying and feeding mechanism 5 and the centrifugal turntable mechanism 3 to stop working to prevent the dolomite flakes from continuing to accumulate in the queue. The discharge end of the buffer slide 61 is located directly above the weighing mechanism, which facilitates the single dolomite flakes on the buffer slide 61 to slide down to the weighing area of ​​the high-precision weighing mechanism 2 under gravity.

[0023] Because dolomite flakes are thin, brittle, and vary in size, relying solely on gravity to slide down the inclined buffer slide 61 can easily lead to stacking, jamming, or obstructed sliding within the slide. This jamming not only interrupts the production process but also often requires manual intervention. To overcome these shortcomings, this embodiment also incorporates a mechanism for actively gripping the dolomite flakes. Specifically, this embodiment also includes a moving suction mechanism in the feeding buffer mechanism 6. This moving suction mechanism comprises a first slide rail 62, a second slide rail 63, a first drag chain 67, and a first vacuum suction component. The first slide rail 62 is arranged parallel to the buffer slide 61, and the second slide rail 63 is perpendicular to the first slide rail 62 and is slidably connected to the first slide rail 62 via a first slider 64. A first driving device drives the second slide rail 63 to move along the length of the first slide rail 62. The first vacuum suction component is slidably connected to the second slide rail 63 via a second slider 65. The first vacuum adsorption assembly is driven to move along the length of the second slide rail 63. One end of the first drag chain 67 is connected to the fixed end of the second slide rail 63 to accommodate and protect the pipeline of the moving suction mechanism. The first vacuum adsorption assembly includes a first vacuum suction cup 66 and a first lifting drive component. The output shaft of the first lifting drive component is vertically downward, and the first vacuum suction cup 66 is installed at the end of the output shaft. The first lifting drive component can drive the first suction cup to move up and down vertically to pick up the dolomite sheet on the buffer slide 61 and place it on the weighing mechanism. The first and second drive devices can be servo motors, stepper motors, etc., and the first lifting drive component can be implemented by a cylinder, electric push rod, or a lead screw mechanism driven by a servo motor.

[0024] The high-precision weighing mechanism 2 includes an electronic scale and a weighing tray 22 mounted on the electronic scale 21. The electronic scale 21 is electrically connected to the electrical control system 4. The electronic scale is equipped with a touch screen 23, which is also electrically connected to the electrical control system 4 and is used to display the current weighing value in real time. After weighing a single piece of dolomite, the high-precision weighing mechanism 2 sends a transport command to the servo material handling mechanism 1.

[0025] like Figure 3As shown, the servo material handling mechanism 1 can drive the vacuum adsorption component to move on the slide rail by driving the drive motor according to the instructions of the electrical control system 4, and accurately transport the weighed dolomite pieces to the material box 14 of the corresponding weight range to complete the final weight division. The system includes a third slide rail 15, a second vacuum adsorption assembly, and a material box 14. The third slide rail 15 is fixedly installed, with one end extending above the weighing platform. The third slider is slidably connected to the third slide rail 15 via a linear guide rail. A third drive motor drives the third slider to reciprocate along the third slide rail 15. The second vacuum adsorption assembly is fixed to the third slider. The second vacuum adsorption assembly includes a second vacuum suction cup 13 and a second lifting drive component 16. The output shaft of the second lifting drive component 16 is vertically downward, and the second vacuum suction cup 13 is installed at the end of the output shaft. A flexible silicone pad is provided at the bottom of the second vacuum suction cup 13. A second drag chain 11 is provided on the third slide rail 15, and a third drag chain 12 is provided on the third slider. The second drag chain 11 is used to protect the power and control cables connected to the slider, and the third drag chain 12 is used to protect the vacuum tube connected to the vacuum suction cup. Multiple inclined slide plates 17 are provided below the third slide rail 15 along its length, and each slide plate 17 has a material box 14 at its discharge end. Each material box 14 corresponds to a weight range. Under the control of the electrical control system 4, the servo material handling mechanism 1 drives the second vacuum adsorption component to pick up a single piece of dolomite from the weighing platform and transfer it to the slide plate 17 in front of the material box 14 of the corresponding weight range. The dolomite piece then slides down the slide plate 17 into the material box 14 of the corresponding weight range again by gravity.

[0026] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included within the protection scope of the present utility model patent application.
