[0028] Specifically, the operator first puts the gypsum raw material block into the hollow box 14 of the equipment; then, the servo motor 11 is started to drive the threaded rod 13 to start rotating; through the rotation of the threaded rod 13, the movable plate 12 is driven to move; this action not only drives the slider 10 to slide in the slide groove 16, ensuring the stability of the movable plate 12 during movement, but also plans the movement trajectory of the movable plate 12; as the movable plate 12 moves, the hollow box 14 also moves; at this time, the vibration motor 9 is started to vibrate the hollow box 14; this step is crucial because it can make the gypsum block fall smoothly from the bottom and avoid clogging at the same time, during the vibration process, the spring 7 plays a buffering role, effectively reducing the impact of vibration on other parts of the equipment and ensuring the stable operation of the equipment; then, the two sets of drive motors 5 are activated to drive the crushing rollers 6 to rotate; the rotation of the crushing rollers 6 is to crush the fallen gypsum blocks; this step ensures that the gypsum raw materials can be processed evenly and carefully, providing a good foundation for the subsequent production process; it is worth mentioning that during the entire feeding process, the vibration motor 9 is always in a state of continuous vibration; this design not only effectively avoids the blockage of the discharge port, but also ensures the stability of the processing efficiency.

[0029] Reference Figure 1 and Figure 3 The screening mechanism 2 includes a bracket 201, a small motor 202 is fixedly connected to the front side of the bracket 201, the output end of the small motor 202 passes through the bracket 201 and is fixedly connected to a driving pulley 203, the left end of the rear side of the bracket 201 is rotatably connected to a driven pulley 208, the driving pulley 203 is connected to the driven pulley 208 through a connecting belt 204, and the rear sides of the driving pulley 203 and the driven pulley 208 are fixedly connected to a percussion hammer 207, a hollow box 206 is installed in the middle of the top wall of the bottom plate 1, and a screening plate 205 is installed on the inner side of the hollow box 206; the two percussion hammers 207 are designed to be staggered;

[0030] Specifically, after the gypsum fragments are crushed, they will naturally fall onto the screening plate 205; at this time, the small motor 202 is started, and it starts to drive the driving pulley 203 to rotate; this rotation action is linked to the driven pulley 208 through the connecting belt 204, thereby driving the two sets of striking hammers 207 to rotate synchronously. This design cleverly utilizes the principle of belt drive to achieve power transmission and distribution; it is worth mentioning that the two groups of percussion hammers 207 adopt a staggered design; this design enables the percussion hammers 207 to more comprehensively cover the area of ​​the screening plate 205 when rotating, thereby improving the screening efficiency; at the same time, the installation of the screening plate 205 is also carefully designed, and multiple screening plates 205 can be installed according to actual use requirements; the size and hole size of these screening plates 205 can also be customized according to specific needs to meet the screening requirements of different particle sizes; when the percussion hammers 207 rotate, they will knock and vibrate the hollow box 206; this vibration effect allows the gypsum powder to be effectively screened on the screening plate 205; during the screening process, the gypsum powder will be separated through the holes on the screening plate 205 according to its particle size, thereby realizing the screening of gypsum powder of different particle sizes.

[0031] Reference Figure 1 and Figure 3 , air bags 19 are installed at both ends of the hammer 207; legs 3 are fixedly connected to the left and right sides of the box body 4; the box body 4 is made of stainless steel;

[0032] Specifically, the airbag 19 reduces the noise during knocking, the legs 3 support the device, and the box body 4 made of stainless steel will not rust after long-term use.

[0033] Working principle: put the gypsum raw material block into the hollow box 14, turn on the servo motor 11 to drive the threaded rod 13 to rotate, and drive the movable plate 12 to move through the rotation of the threaded rod 13. When the movable plate 12 moves, the slider 10 is driven to slide in the slide groove 16, which is used for the limit work when the movable plate 12 moves. At the same time, the moving trajectory of the movable plate 12 is planned, and the hollow box 14 is moved by the movement of the movable plate 12. Turn on the vibration motor 9 to vibrate the hollow box 14, and the gypsum block falls from the bottom through vibration. During vibration, the spring 7 is used to buffer the vibration force to avoid affecting the operation of the equipment. Turn on the two sets of drive motors 5 to drive the crushing roller 6 to rotate, and the gypsum block is crushed by the rotation of the crushing roller 6. When feeding, the vibration motor 9 is in a state of continuous vibration, thereby avoiding the situation where the discharge port is blocked, and after crushing, the gypsum fragments naturally fall on the screening plate 205, and the small motor 202 is turned on to drive the active pulley 203 to rotate. The rotation of the active pulley 203 is linked to the driven pulley 208 through the connecting belt 204, thereby driving the two groups of percussion hammers 207 to rotate synchronously. The two groups of percussion hammers 207 adopt a staggered design, and the screening plate 205 is installed with multiple hammers. The size and hole size of the screening plate 205 can be determined according to actual use.
