A drive motor is set on the transverse screw, and the drive motor drives the screening slider to move parallel to the transverse screw under the control of the controller. The feeding slider and the screening slider on the transverse lead screw do not interfere with each other.

[0044] The automatic sieving mechanism includes a sieving screw 1, a pneumatic cylinder 2, an "S"-shaped extrusion rake 3, a screening frame 4, and a pressure sensor 5. The sieving screw is mounted on a sieving platform, parallel to the Z-axis. The pneumatic cylinder is mounted on the sieving screw. The "S"-shaped extrusion rake is mounted below the pneumatic cylinder and fixedly connected to its actuating end. A vertical slide is provided on the sieving screw, allowing the "S"-shaped extrusion rake to rise and fall along this slide under the influence of the pneumatic cylinder. An explosion-proof pneumatic motor is installed on the "S"-shaped extrusion rake, enabling it to rotate 360°. The screening frame is mounted on the sieving screw and located below the "S"-shaped extrusion rake. A screen is installed inside the screening frame, and a funnel is connected below the frame, with a collection box for undersize material at the bottom of the funnel.

[0045] The automatic sieving mechanism has a sieving screw that is shorter than the feeding screw.

[0046] An automated sieving method for RDX (rhexane) includes:

[0047] The material tank 8 is embedded in the pneumatic motion platform of the automatic feeding mechanism. The medicine is put into the material tank. The controller controls the pneumatic motor to work. The pneumatic motor drives the pneumatic motion platform to slide smoothly along the feeding screw 6 to the automatic feeding mechanism.

[0048] After the movement is in place, the controller controls the feeding motor of the automatic feeding mechanism to work. The feeding motor drives the tub arc-shaped manipulator 9 to descend along the feeding screw 10 to the tub. Under the control of the controller, the tub clamping motor drives the tub arc-shaped manipulator 9 to close its claws to clamp the tub. After the tub is clamped, the feeding motor drives the feeding slider to move laterally along the transverse screw 13 to above the screening frame 4 under the control of the controller. Then, the tub flipping motor drives the tub arc-shaped manipulator to flip under the control of the controller, so that the medicine is poured into the screening frame 4 that has been placed in place in advance by the manual. Then the empty tub is sent back to the automatic feeding mechanism along the original path.

The screening frame clamping motor drives the screen frame arc-shaped robot arm to close its claws under the control of the controller to clamp the screening frame.

[0050] The controller controls the pneumatic cylinder of the automatic sieving mechanism. The "S"-shaped squeezing rake 3 rises and falls along the vertical slide on the sieving screw under the drive of the pneumatic cylinder 2. It rotates 360° under the action of the explosion-proof pneumatic motor, thereby squeezing and shearing the agent in the screening frame, so that the agent passes through the screen and falls into the undersize collection box that has been placed in advance by the operator. After the screening is completed, the "S"-shaped squeezing rake rises along the vertical slide on the sieving screw under the drive of the pneumatic cylinder and leaves the screening frame.

[0051] The controller controls the unloading motor to work, which drives the screen frame arc-shaped manipulator 11 to rise along the unloading screw 12. After rising to the position, the controller controls the unloading motor to work, which drives the unloading screw to move laterally along the transverse screw 13 to the unloading collection box 17 of the automatic discharge mechanism. Then, the controller controls the screen frame flipping motor to work, which drives the screen frame arc-shaped manipulator to flip, so that the unloading material remaining on the screen frame is poured into the unloading collection box that has been placed in place by the operator in advance.

[0052] After sieving, the motor on the automatic discharge mechanism drives the undersize collection box 15 to move along the undersize discharge screw 14 to the discharge port, and the oversize collection box 16 to move along the undersize discharge screw 17 to the discharge port. Then, the undersize and oversize are removed manually.

[0053] This invention enables the automatic extrusion and sieving of RDX (rapid-induced coronary artery disease) without generating dust, completely freeing up manual labor, reducing labor intensity, and avoiding hazards such as swollen arms and blisters on the palms of workers during operation, thus eliminating occupational safety threats to employees.

[0054] Example:

[0055] like Figure 1-2 As shown, the motion platform is mounted above three feed screws 6 parallel to the X-axis. Under the control of a pneumatic motor, the pneumatic motion platform 7 can smoothly slide on the feed screws 6. The container 8 containing the medicine is placed on the pneumatic motion platform 7. The bottom outline of the container matches the platform size, allowing the container to be stably embedded in the platform, ensuring that the container does not tip over during the feeding process. The medicine is manually loaded into the raw material feed container and placed at the feeding station. After setting the motor rotation time by clicking on the operation control interface, clicking "Start Run" initiates the feeding program. The automatic feeding and dispensing mechanism begins automatic operation, and the cylinder delivers the medicine container to the feeding station. The medicine container has a size of φ240mm. 130mm, large enough to hold 4kg of RDX, hexanitrode, and other high explosives.

[0056] Table 1. Control Interface Button Description

[0057]

[0058] The human-machine interface for drug screening is as follows: Figure 3 As shown.

[0059] After the medicine container is delivered to the feeding station, the automatic feeding mechanism begins operation. The motor controls the raising and lowering, opening and closing of the gripper on the feeding screw 10, allowing the curved robotic arm 9 to precisely hold the medicine container 8 transported by the automatic feeding mechanism. After holding the medicine container 8, the curved robotic arm 9 moves along the feeding screw 10 to above the screening frame 4 on the transverse screw 13, then flips to pour the medicine from the medicine container 8 into the screening frame 4. The screening frame 4 is a custom-made mesh sieve, and the frame is replaceable. After the raw material is poured out, the curved robotic arm 9 returns the medicine container 8 to the feeding mechanism station.

[0060] At this point, the reagent reaches the screening frame. The arc-shaped manipulator 11 of the screening frame clamping mechanism, under the control of the clamping motor, clamps the screening frame, fixing it in place. Subsequently, the automatic sieving mechanism begins operation. The sieving mechanism consists of a sieving screw 1, a pneumatic cylinder 2, an "S"-shaped extrusion rake 3, a screen frame 4, and a pressure sensor 5. The pneumatic cylinder is installed above the sieving screw and can rise and fall along the screw under pneumatic conditions. The "S"-shaped extrusion rake is installed below the pneumatic cylinder, and a small pressure sensor is connected between the extrusion rake and the pneumatic cylinder. The "S"-shaped extrusion rake is raised and lowered via a vertical slide, rotating and extruding 360° on the screen. The part of the "S"-shaped extrusion rake that extrudes the reagent is made of rubber, which is fixed to metal blades. Between the screening frame and the undersize collection box is a funnel-structured collection device. The undersize enters the undersize collection box 15 through the inclined surface of the funnel, reducing the diffusion of reagent dust. The device applies pressure and shearing force to the agent, forcing it through a sieve. The undersize material enters the undersize collection box 15. An explosion-proof pneumatic motor rotates the "S"-shaped pressure rake 360° across the sieve, applying pressure and shearing force to the agent and forcing it through the sieve. The "S"-shaped pressure rake has a certain angle, ensuring the agent is compressed and preventing it from rotating with the rake. The pressure between the "S"-shaped pressure rake and the sieve can be precisely adjusted by changing the air pressure.

[0061] After the reagent is sieved, it enters the undersize collection box. The "S"-shaped extrusion rake leaves the screening frame. The screen frame clamping mechanism's arc-shaped manipulator 11, under the control of the clamping motor, clamps the screening frame 4 and rises along the screen oversize discharge screw 12. As the screen oversize discharge screw 12 moves along the transverse screw 13, it moves above the screen oversize collection box 17. The screen frame arc-shaped manipulator 11 then flips the screen oversize in the screening frame 4 and pours it into the screen oversize collection box 17.

[0062] The automatic discharge mechanism starts working. The motor drives the undersize collection box 15 to move along the undersize discharge screw 14 to the discharge port, and the oversize collection box 16 to move along the undersize discharge screw 17 to the discharge port. Then, the undersize and oversize are removed by manual labor.

An automatic sieving device for RDX (rhexane) according to claim 2, characterized in that: The automatic discharge mechanism includes an undersize discharge screw, an undersize discharge motion platform, an oversize discharge screw and an oversize discharge motion platform, an oversize pneumatic motor, and an undersize pneumatic motor. The undersize discharge screw is parallel to the X-axis. The undersize pneumatic motor is mounted on the undersize discharge screw. The undersize discharge motion platform is mounted on the actuating end of the undersize pneumatic motor. Under the control of the controller, the undersize pneumatic motor drives the undersize discharge motion platform to slide smoothly along the undersize discharge screw. The undersize discharge motion platform has a slot for embedding an undersize collection box. The oversize discharge screw is parallel to the X-axis. The oversize pneumatic motor is installed on the oversize discharge screw. The oversize discharge motion platform is installed on the actuating end of the oversize pneumatic motor. Under the control of the controller, the oversize pneumatic motor drives the oversize discharge motion platform to slide smoothly along the oversize discharge screw. The oversize discharge motion platform has a slot for embedding the oversize collection box.

8. The automatic sieving method for RDX (rDX) using the automatic sieving device for RDX as described in claim 7, characterized in that, include: The material tank is embedded in the pneumatic motion platform of the automatic feeding mechanism. The medicine is put into the material tank. The controller controls the pneumatic motor to work. The pneumatic motor drives the pneumatic motion platform to slide smoothly along the feeding screw to the automatic feeding mechanism. Once the movement is in place, the controller activates the feeding motor of the automatic feeding mechanism. The feeding motor drives the curved robotic arm of the material tank down along the feeding screw to the material tank. Under the control of the controller, the material tank clamping motor drives the curved robotic arm of the material tank to close its claws to clamp the material tank. After the material tank is firmly clamped, the feeding motor drives the feeding slider to move laterally along the transverse screw to the sieving position under the control of the controller. Then, the material tank tilting motor drives the curved robotic arm of the material tank to tilt under the control of the controller, so that the medicine is poured into the screening frame that has been placed in advance by the operator. The controller controls the unloading motor to work, which drives the screen frame arc-shaped robotic arm to descend along the unloading screw of the material on the screen to the screening frame. Under the control of the controller, the screening frame clamping motor drives the screen frame arc-shaped robotic arm to close its claws to clamp the screening frame. The controller controls the pneumatic cylinder of the automatic sieving mechanism. The "S"-shaped squeezing rake rises and falls along the vertical slide on the sieving screw under the drive of the pneumatic cylinder. It rotates 360° under the action of the explosion-proof pneumatic motor, thereby squeezing and shearing the agent in the screening frame, so that the agent passes through the screen and falls into the undersize collection box that has been placed in advance by the operator. After the screening is completed, the "S"-shaped squeezing rake rises along the vertical slide on the sieving screw under the drive of the pneumatic cylinder and leaves the screening frame. The controller controls the unloading motor to work, which drives the arc-shaped robotic arm of the screen frame to rise along the unloading screw of the screen material. After rising to the position, the controller controls the unloading motor to work, which drives the unloading screw of the screen material to move laterally along the transverse screw to the screen material collection box of the automatic discharge mechanism. Then, the controller controls the screen frame flipping motor to work, which drives the arc-shaped robotic arm of the screen frame to flip, so that the screen material remaining on the screen frame is poured into the screen material collection box that has been placed in place in advance by the operator. The undersize collection box is manually inserted into the undersize discharge platform. Under the control of the undersize pneumatic motor, the undersize discharge platform slides smoothly along the undersize discharge screw, transporting the embedded undersize collection box to the discharge port. The oversize discharge platform is controlled by the oversize pneumatic motor, and slides smoothly along the oversize discharge screw, transporting the embedded oversize collection box to the discharge port. The undersize collection box and oversize collection box are then manually removed.
