[0040] As a technical solution of this embodiment, further, Figure 7 As shown, the well-type feeding unit 500 includes a mounting platform 510, a loading pipe 520 arranged on the mounting platform 510, a feeding device 530 arranged on one side of the loading pipe 520, and a positioning block 540 arranged on the other side of the loading pipe 520 and opposite to the feeding device 530.

[0041] The well feeding unit 500 is a component of the material feeding and sorting system, which is used to deliver raw materials or semi-finished products into production in a certain order and quantity. The well feeding unit 500 is the starting unit of the equipment. It plays the role of warehousing and providing raw materials to other units in the entire system. It automatically pushes out materials of different colors in the silo as needed and passes them to the next working unit, namely the stepping slide unit 600.

[0043] The stepper slide unit 600 is mainly responsible for material transportation throughout the entire system, transporting materials of different colors from the silo area to the area to be grasped, that is, below the rotary suction unit 700. This function is often used in industrial production lines for more precise material transportation. It uses a servo motor or stepper motor with a screw drive structure, and the pneumatic gripper 633 clamps the material. It is sturdy and durable, and has good operating stability.

[0045] The main function of the rotary suction unit 700 is to absorb, lift and transport the material to the head end of the belt conveyor unit 800 for subsequent sorting tasks. The rotary suction unit 700 mainly uses pneumatic components such as lifting cylinders, rotating cylinders, and suction cups to complete the work tasks of this process. When the stepping slide unit 600 transports the material to the area to be grasped, the cylinder of the rotary suction unit 700 descends and absorbs the material, and then the lifting cylinder is lifted, and the rotating cylinder drives the connecting frame 730 to rotate to the feeding end of the belt conveyor unit 800. Finally, the lifting cylinder descends and places the material on the belt line, thereby completing the grasping and transporting work of the material by the rotary suction unit 700.

[0048] As a technical solution of this embodiment, further, Figure 11 The sorting unit 900 shown includes a sorting bracket 910 arranged on the training platform 100, a pushing device 920 horizontally arranged on the sorting bracket 910, and a color mark sensor 930 arranged above the pushing device 920.

The pushing cylinder 940 is connected to the pneumatic valve group 200 through an air guide pipe.

[0049] The main function of the sorting unit 900 is to sort incoming materials of different colors into storage. When the belt conveyor line transports materials of different colors, the color mark sensor 930 identifies them in advance and transmits the color information of the materials to the main control module 310. The sorting mechanism then performs sorting actions for materials of different colors. Specifically, the main control module 310 sends instructions to the pneumatic valve group 200, and the pneumatic valve group 200 supplies air to the pushing cylinder 940 corresponding to the color mark sensor 930. The telescopic rod of the pushing cylinder 940 pushes the pushing block 950, and then sorts the materials of the same color into the corresponding sub-bin 120, thereby completing the sorting task of materials of different colors.

[0052] The fountain simulation unit 410 contains 20 LED lights and uses the same operating logic as a musical fountain. The LED indicators are programmed using a Siemens S7-200smart controller to create a fountain effect. A control switch 413 and a first signal interface 414 are located on the first teaching board 411, allowing participants to understand the principles of logical control while also developing their wiring skills. This unit utilizes a quick-change design. During the experiment, remove the fountain simulation unit 410 and place it on the pull-out control cabinet 300. Wires are then used to connect the PLC I / O points to the buttons and indicator lights, and the simulation begins. Once completed, the fountain simulation unit 410 is returned to the bottom of the pull-out control cabinet 300 to conserve space.

[0053] Example 2:

[0054] like Figure 6 The traffic signal simulation unit 420 shown includes a second teaching board 421, a second countdown device 422, a traffic signal simulation light group 423 and a second signal interface 424.

[0055] The traffic signal simulation unit 420 simulates the operating logic of traffic lights in real-life intersections. It uses yellow, green, and red LED indicators to simulate traffic lights in the four directions of east, west, south, and north, and uses digital tubes to simulate the time display of traffic lights. During the experiment, the traffic signal simulation unit 420 is taken out and placed on the pull-out control cabinet 300. After the trainees complete the connection of the traffic light circuit through the PLC, they download the program into the PLC and press the start button to verify their program. The control of the traffic light is achieved through program modification and testing. After completing the training, the traffic signal simulation unit 420 is placed back on the bottom of the pull-out control cabinet 300.
