Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 —3, a powder anti-misfilling system based on RFID technology, including a feeding platform 100, a transfer trolley 200, a feeding hopper 300, an information writing RFID terminal 401, an information reading RFID terminal 402, an information erasing RFID terminal 403, and a main control device 404. First, a transfer trolley 200 is provided on the feeding platform 100, so that the transfer trolley 200 can move linearly on the feeding platform 100. Multiple sets of feeding hoppers 300 are provided on one side of the feeding platform 100. Each set of feeding hoppers 300 is equipped with a powder processing device. An RFID chip 207 is fixedly connected to the transfer trolley 200.

[0026] Furthermore, an information writing RFID terminal 401 is fixedly connected to one end of the feeding platform 100. Information can be written into the RFID chip 207 through the information writing RFID terminal 401. At the same time, an information reading RFID terminal 402 is fixedly connected to each set of feeding hoppers 300 on the feeding platform 100. The information reading RFID terminal 402 can read the information stored in the RFID chip 207 through the information reading RFID terminal 402. In addition, an information erasing RFID terminal 403 is fixedly connected to the other end of the feeding hopper 300 on the feeding platform 100. The information erasing RFID terminal 403 can erase the information stored in the RFID chip 207 through the information erasing RFID terminal 403.

[0027] Furthermore, each feeding hopper 300 on the feeding platform 100 is fixedly connected to a feeding mechanism 500. The feeding mechanism 500 works in conjunction with the transfer trolley 200 to feed the powder stored in the transfer trolley 200.

[0028] To achieve automated control, the main control device 404 includes a PLC controller and a computer device. The aforementioned information writing RFID terminal 401, information reading RFID terminal 402, information erasing RFID terminal 403, and feeding mechanism 500 are all connected to the PLC controller, and the PLC controller is connected to the computer device.

[0029] In summary, the transfer trolley 200 can transfer powder. When the corresponding information of the transfer trolley 200's movement is written into the RFID terminal 401, the staff can write the powder information into the RFID chip 207 through the computer device according to the powder specifications. Then, the corresponding information of the transfer trolley 200's continued movement is read from the RFID terminal 402. After the information reading RFID terminal 402 reads the information in the RFID chip 207, if the read information matches, the feeding mechanism 500 controls the transfer trolley 200 to feed the powder into the corresponding feeding hopper 300. When the information reading RFID terminal 402 reads the information in the RFID chip 207, if the read information does not match, the transfer trolley 200 continues to move until the corresponding information matches, and the powder is fed into the corresponding feeding hopper 300. Finally, the corresponding information of the transfer trolley 200's movement is erased from the RFID terminal 403, and the information stored in the RFID chip 207 is erased by the information erasure RFID terminal 403.

[0030] In this embodiment, the transfer trolley 200 is equipped with a powder storage box 201. The top of the powder storage box 201 adopts an open structure. A discharge port 202 is provided on one side of the powder storage box 201. A closing plate 203 is slidably connected to the powder storage box 201. Specifically, sliding columns 204 are fixedly connected to both sides of the powder storage box 201 near the discharge port 202. The closing plate 203 is provided with sliding holes to cooperate with the sliding columns 204. The sliding columns 204 are slidably connected in the sliding holes. The closing plate 203 closes the discharge port 202. The feeding mechanism 500 cooperates with the closing plate 203 so that the feeding mechanism 500 can drive the closing plate 203 to slide, so that the closing plate 203 opens the discharge port 202. In this way, the powder in the powder storage box 201 can be discharged from the discharge port 202. Of course, in order to ensure that all the powder is discharged, an inclined platform 205 is provided in the powder storage box 201, and the inclined platform 205 faces the discharge port 202.

[0031] In this embodiment, the feeding mechanism 500 includes a mounting frame 501, an electric telescopic cylinder 502, and an electromagnet 503. The mounting frame 501 is fixedly connected to the feeding platform 100, and a traction frame is slidably connected to the mounting frame 501. Specifically, the traction frame includes a mounting frame 504 and a guide post 505 fixedly connected to the mounting frame 504. The electromagnet 503 is fixedly connected to the mounting frame 504. The mounting frame 501 has a guide hole through which the guide post 505 passes. The electric telescopic cylinder 502 is fixedly connected to the mounting frame 501, and the piston end of the electric telescopic cylinder 502 is connected to the mounting frame 504. A fixed connection is made, and an adsorption platform 206 is fixedly connected to the closed plate 203. The electromagnet 503 cooperates with the adsorption platform 206. In this way, the electric telescopic cylinder 502 can drive the electromagnet 503 to descend until the electromagnet 503 adsorbs the adsorption platform 206. Then, the electric telescopic cylinder 502 can drive the closed plate 203 to rise, thereby opening the discharge port 202. After the powder is discharged, the electromagnet 503 is de-energized, and then the closed plate 203 slides down under the action of gravity, closing the discharge port 202. In order to achieve automatic control, the electric telescopic cylinder 502 and the electromagnet 503 are both connected to the PLC controller signal.
