Two sets of rotating rods 17 are rotatably installed inside the molding box 7. Pressure rollers 18 are installed on the outer walls of both sets of rotating rods 17. Multiple sets of hemispherical grooves 19 are opened on the outer walls of both sets of pressure rollers 18. Two sets of inclined guide plates 14 are installed inside the molding box 7. The lower ends of the two sets of inclined guide plates 14 are located directly above the middle of the two sets of pressure rollers 18. One end of one set of rotating rods 17 is fixed to the output end of the variable speed motor 10, and the other ends of both sets of rotating rods 17 are fixed to the two movable ends of the transmission assembly 16. The variable speed motor 10 is connected to the control panel 2 via signal.
[0019] The specific settings and functions of this embodiment are described below. The support frame 1, as the core support component of the equipment, is welded from Q345 high-strength low-alloy steel and has an overall frame structure. The bottom is fixed to the ground by expansion bolts to ensure the stability of the equipment during operation. The control panel 2 is integrated on one side of the support frame 1, and the other side is slidably connected to the movable frame 3 through a slide rail, so that the position of the movable frame 3 can be flexibly adjusted according to the space of the production site. The control panel 2 adopts an integrated design of industrial-grade touch screen and PLC controller. The panel surface is covered with scratch-resistant and wear-resistant tempered glass, which has waterproof and dustproof functions. The control panel 2 is equipped with a high-performance processor, which can receive and process the signals fed back by each mechanism in real time, and send control commands to the screw feeding mechanism 5, conveying mechanism 8, material level sensor 15, variable speed motor 10 and telescopic rod 13 to realize the fully automated operation of the equipment. Feeding module: The mobile frame 3 is made of aluminum alloy profiles, which is lightweight and high-strength. It is equipped with universal wheels with brakes at the bottom for easy movement and fixing. The storage bin 4 and the spiral feeding mechanism 5 are bolted inside the mobile frame 3. The two are distributed vertically, with a compact structure that saves equipment floor space. The storage bin 4 is made of stainless steel with a polished inner wall to prevent the lightly burned magnesium powder from sticking together. The top is equipped with a sealed cover to prevent dust from leaking out and polluting the environment. The bottom has an inverted cone-shaped structure to facilitate the concentrated falling of materials to the feed port of the screw feeding mechanism 5. A material level sensor 15 is installed on the inner wall of the storage bin 4 near the discharge port. This sensor uses the infrared sensing principle to monitor the remaining amount of material in the bin in real time. The spiral feeding mechanism 5 consists of a servo motor, spiral blades, a conveying pipe, and a bearing housing. The spiral blades are made of wear-resistant manganese steel and coated with tungsten carbide to extend their service life. The inner wall of the conveying pipe is smooth to reduce material conveying resistance. The feed inlet of the spiral feeding mechanism 5 is sealed and fixed to the discharge port of the storage bin 4 through a flange. The discharge port at the lower end is welded with a discharge pipe 6 to ensure no leakage during material conveying. The feeding pipe 6 is made of seamless stainless steel pipe. The pipe diameter is designed to match the output of the spiral feeding mechanism 5. The lower end is sealed and fixed to the upper opening of the forming box 7 through a quick-release connector, which facilitates disassembly and cleaning later. Molding module: The molding box 7 is made of welded steel plates, with an external insulation layer and an internal anti-corrosion treatment. One end of the molding box 7 is fixedly mounted with a variable speed motor 10 via a motor mount, and the other end is mounted with a transmission assembly 16 via a bracket. Inside, two sets of rotating rods 17 are mounted in parallel rotation. The variable speed motor 10 is a variable frequency speed control motor, which can flexibly adjust the speed according to the molding requirements of lightly sintered magnesium balls. The motor is also equipped with overload protection function, which automatically stops the machine when the load exceeds the set value to protect the safety of the equipment. The transmission assembly 16 consists of a driving gear, a driven gear, and a gearbox. The driving gear is fixedly connected to one end of one set of rotating rods 17, and the driven gear is fixedly connected to one end of another set of rotating rods 17. The two sets of gears mesh with each other, and the driving gear and the driven gear maintain a precise center distance inside the gearbox. Power is transmitted through tooth surface meshing. When the motor drives the driving gear to rotate, the driven gear rotates in the opposite direction due to the meshing force, which in turn drives the two sets of rotating rods 17 to move synchronously in the opposite direction, providing basic power for the pressing action and ensuring that the two sets of rotating rods 17 rotate synchronously inward, thus ensuring the stability of the pressing process. The rotating rod 17 is made of 45 steel and heat treated. Both ends are rotatably connected to the side wall of the forming box 7 through bearings. The pressure roller 18 is made of high chromium cast iron and is fixed to the rotating rod 17 through a key connection. The outer walls of both sets of pressure rollers 18 are provided with multiple sets of hemispherical grooves 19. The diameter and depth of the grooves can be customized according to the specifications of the light-burned magnesium balls. The inner walls of the grooves are polished to facilitate the removal of the formed magnesium balls. Two sets of inclined guide plates 14 are symmetrically installed inside the forming box 7. They are made of stainless steel and coated with polytetrafluoroethylene to reduce material adhesion. The upper end of the inclined guide plate 14 is fixed to the inner wall of the forming box 7, and the lower end is inclined directly above the middle of the two sets of pressure rollers 18 at an angle of 30-45° to ensure that the lightly calcined magnesium powder falling from the feed pipe 6 can be accurately collected between the two sets of pressure rollers 18. Conveying module: The conveying mechanism 8 consists of a drive motor, a conveyor belt, a drive roller, a driven roller, and a frame. The drive motor is a geared motor, which is connected to the drive roller via a chain to drive the conveyor belt to run at a constant speed. The conveyor belt is made of high-strength rubber material, and a protective pad 11 is installed on its surface. The protective pad 11 is made of silicone material, which has anti-slip and wear-resistant properties to prevent the magnesium balls from sliding and colliding during the conveying process.
[0020] Example 2: Figure 1 , Figure 2 and Figure 5 As shown, a protective pad 11 is installed on the outer wall of the conveyor belt in the conveying mechanism 8. Two sets of diagonal braces 9 are installed on both sides of the frame of the conveying mechanism 8. Two sets of baffles 12 are set on the top of the conveying mechanism 8. Telescopic rods 13 are installed through one side of each of the four sets of diagonal braces 9. The extended ends of every two sets of telescopic rods 13 are fixed to one side of a set of baffles 12. All four sets of telescopic rods 13 are connected to the control panel 2 for signal connection.
[0021] The overall effect of this embodiment is that two sets of diagonal bracing frames 9 are welded on both sides of the frame of the conveying mechanism 8. The diagonal bracing frames 9 are triangular in structure to enhance the stability of the support. Telescopic rods 13 are installed through one side of each of the four sets of diagonal bracing frames 9. The telescopic rods 13 are electric push rods. The extended ends of every two sets of telescopic rods 13 are fixed to one side of a set of baffles 12 by bolts. The baffles 12 are made of transparent acrylic sheets to facilitate the operator's observation of the magnesium ball conveying.
[0022] The operation and working principle of this device are as follows: The operator first adds the lightly calcined magnesium powder into the storage silo 4 through the sealed cover at the top. The inverted conical structure at the bottom of the storage silo 4 causes the material to naturally converge towards the discharge port. The material level sensor 15 installed on the inner wall of the storage silo 4 near the discharge port monitors the material level in the silo in real time. When the remaining material level is lower than the preset lower limit value of the control panel 2, the sensor immediately sends a signal to the control panel 2, and the touch screen on the panel pops up a "Material Insufficient" warning to remind the operator to replenish the material in time. Then, the operator sets the feeding parameters (such as feeding amount and feeding speed) through the control panel 2 and starts the equipment. The control panel 2 sends a start command to the servo motor of the screw feeding mechanism 5. The servo motor drives the screw blades to rotate at high speed in the conveying pipe. The light calcined magnesium powder in the storage bin 4 enters the feed port of the screw feeding mechanism 5 from the discharge port of the storage bin 4 under the action of gravity and the pushing force of the screw blades, and is stably conveyed forward along the inner wall of the conveying pipe. The lightly calcined magnesium powder conveyed by the spiral feeding mechanism 5 enters the feeding pipe 6 from the lower discharge port. The feeding pipe 6 is sealed to the upper opening of the molding box 7 through a quick-release connector. Under the action of gravity, the material falls vertically into the molding box 7 along the feeding pipe 6, completing the feeding stage process. The lightly calcined magnesium powder falling from the feeding pipe 6 into the forming box 7 first comes into contact with two sets of inclined guide plates 14 symmetrically installed inside the forming box 7. The inclined guide plates 14 are inclined at an angle of 30-45° and are coated with polytetrafluoroethylene (low coefficient of friction, reducing material adhesion). They can accurately guide the dispersed falling magnesium powder directly above the middle of the two sets of pressure rollers 18, avoiding material deviation that would cause uneven force on the pressure rollers 18 or insufficient material in the forming process. Through two sets of variable speed motors 10, two sets of rotating rods 17 and transmission components 16, the two sets of pressure rollers 18 can be driven to rotate. After the lightly calcined magnesium powder falls between the two sets of pressure rollers 18 that rotate inward synchronously, it is rolled into the hemispherical grooves 19 on the outer wall of the pressure rollers 18. As the pressure rollers 18 continue to rotate, the hemispherical grooves 19 of the two sets of pressure rollers 18 gradually close, applying extrusion pressure to the magnesium powder in the grooves. When the pressure roller 18 rotates to the position where the hemispherical groove 19 is completely separated, the formed lightly sintered magnesium ball will naturally fall out of the hemispherical groove 19 under the combined action of its own gravity and the polished surface of the inner wall of the hemispherical groove 19 (reducing adhesion) and fall into the conveying mechanism 8 below, completing the forming stage process. The conveying mechanism 8 drives the formed light-burned magnesium balls to be conveyed, which facilitates the feeding of the light-burned magnesium balls.
[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
