The feeding mechanism 6 includes a bracket, a material cylinder 18, a feeding cylinder 15, a pushing cylinder 13, and a hopper 21. The bracket includes a bottom plate 7, a pillar 8, and a top plate 9. The bottom plate 7 is fixedly installed on the platform 1.

The feeding cylinder 15 and the pushing cylinder 13 are placed perpendicular to each other. A material bin 17 is provided at the bottom of the material cylinder 18. The feeding plate 16 of the feeding cylinder 15 faces the right side opening of the material bin 17. The pushing plate 14 of the pushing cylinder 13 is located in front of the left side opening of the material bin 17. A baffle 19 extending upward to the right is installed at the left end of the top plate 9. The front end of the top plate 9 is connected to the hopper 21 fixedly installed on the platform 1 through an inverted material inclined plate 20. The feeding cylinder 15 and the pushing cylinder 13 are connected to the solenoid valve 11 through a bronchus 12. The solenoid valve 11 is connected through a main air pipe 10. In the electrical cabinet, there is a PLC controller and a terminal block 4. The terminal block 4 is connected by wiring to the PLC controller and the solenoid valve 11.

[0023] A wire groove 5, a control button 2, and a working status light 3 are also installed on the platform 1. The control button 2 and the working status light 3 are electrically connected to the PLC controller.

[0024] Handles 22 are provided on the left and right sides of the platform 1. Adjustable height support feet 23 are also provided at the four corners of the platform 1.

[0025] Both the platform 1 and the pillar 8 on the bracket are assembled from standard aluminum profiles. The main body of the platform 1 is a plate-like structure formed by splicing multiple standard aluminum profiles side by side.

[0026] The terminal block 4, the bracket, the wire groove 5, the control button 2, and the working status light 3 are all detachably installed on the platform 1 through aluminum profile fasteners and can be installed on any standard aluminum profile.

[0027] Working principle of this embodiment:

[0028] This embodiment is mainly composed of a platform 1, a feeding mechanism 6, an electrical cabinet, and supporting control components. The platform 1 serves as the foundation of the entire device, bearing and fixing all other components. The feeding mechanism 6 is the core execution unit, responsible for the feeding and control of materials, including key components such as a bracket, a material cylinder 18, a feeding cylinder 15, a pushing cylinder 13, and a hopper 21. The electrical cabinet integrates a PLC controller, which is connected to pneumatic components such as the solenoid valve 11 through the terminal block 4 to achieve the combination of electricity and pneumatics.

[0029] Material feeding process: When the PLC controller receives the material feeding instruction, it sends a signal to the solenoid valve 11 through the terminal block 4. After receiving the signal, the solenoid valve 11 controls the bronchus 12 to supply air to the material feeding cylinder 15, causing the material feeding plate 16 to move forward and pushing the material to slide out from the right side opening of the bin 17 at the bottom of the material cylinder 18. During this process, the baffle 19 at the left end of the top plate 9 plays a role in preventing the material from scattering from the side. Pushing process: Immediately afterwards, the PLC controller controls the pushing cylinder 13 to work through the solenoid valve 11 again. The pushing plate 14 of the pushing cylinder 13 is located in front of the left side opening of the bin 17. When receiving the signal, the pushing plate 14 is pushed forward to push the material that has slid out of the bin 17 towards the pouring inclined plate 20. Material collection: The material slides down along the pouring inclined plate 20 into the hopper 21 fixedly installed on the platform 1, completing the entire material feeding process.

[0030] Control signal input: The user sends operation instructions such as start and stop to the PLC controller through the control button 2. At the same time, the PLC controller monitors the state of the solenoid valve 11 in real time through the terminal block 4 to ensure the accurate transmission and execution of the control signal. Status feedback: The PLC controller controls the lighting and extinguishing of the working status lamp 3 according to the received instructions and the feedback signals that may be included in the sensors although not directly mentioned, visually showing the operating status of the device to the user, such as normal operation, fault alarm, etc. Program logic: The PLC controller internally presets a control program for material feeding and pushing. This program controls the opening and closing of the solenoid valve 11 according to the input control signal, and then drives the actions of the material feeding cylinder 15 and the pushing cylinder 13 to achieve precise material delivery.

[0031] In this embodiment, both the platform 1 and the pillar 8 of the bracket are assembled from standard aluminum profiles. The main body of the platform 1 is a plate-like structure formed by splicing multiple standard aluminum profiles side by side. The modular design makes the device more convenient during assembly, disassembly, and transportation. Due to the use of standardized components, the device can be flexibly adjusted in layout according to the needs of the teaching environment to adapt to the space limitations of different classrooms or laboratories; components such as the terminal block 4, the bracket, the wire groove 5, the control button 2, and the working status lamp 3 are all detachably installed on the platform 1 through aluminum profile fasteners and can be installed on any standard aluminum profile. According to the specific requirements of teaching experiments, functional modules can be easily added or replaced to achieve customized upgrading of the device. The handles 22 provided on both sides of the platform 1 and the adjustable height support feet 23 at the four corners improve the mobility and stability of the device. When used in the classroom, the platform 1 can be placed on the desktop, and the electrical cabinet can be placed below the desktop, which is convenient for keeping the desktop clean and conducive to classroom teaching.

[0032] This embodiment has a compact structure, strong function expandability, and is easy to manufacture and maintain, effectively solving the defects of the existing training devices such as large volume, increased weight, and single function.
