[0028] Discharge hopper 3 is solidly arranged at the feed end of one of the conveying belts 1, and the discharge end of the adjacent conveying belt 1 is connected with the link plate 4;

[0029] The material shifting mechanism 5 is arranged on one side of the link plate 4, and the material shifting mechanism 5 is used to guide the test paper bag to walk.

[0030] It should be noted that the device is the main structure of the intelligent sorting equipment, and the device further includes a main control board, a core of the control system, which is responsible for receiving data from the RFID reader-writer 203, and processing the data according to the preset rules, driving the control board, communicating with the main control board, controlling the movement of the conveying belt 1, the electric push rod 503 and other driving components, so as to realize the movement and sorting of test paper bag, LED display screen, display device working state and label detection result, provide intuitive operation feedback, and setting the receiving device below the discharge hopper 3.

[0031] Work flow​

[0032] Identification stage: After the test paper bag enters the sorting equipment, the test paper bag moves on the conveying belt 1 to the identification assembly 2, the RFID reader-writer 203 in the identification assembly 2 reads the RFID tag information on the test paper bag, and transmits the information to the control system (not shown in the device, mentioned in the foregoing).

[0033] Sorting stage: According to the identified information, the control system instructs the material shifting mechanism 5 to guide the test paper bag to the corresponding conveying belt 1, and each discharge hopper 3 corresponds to a kind of test paper bag with a label, when a certain kind of test paper bag conveying belt reaches its designated discharge hopper 3, the material shifting mechanism 5 will guide it to the discharge hopper 3, so that it falls from the discharge hopper 3.

[0034] The test paper bag packaging batch classification equipment adopts modular design, uses multiple short conveying belts 1 instead of one long conveying belt 1, is more simple to install and maintain, and the several-character-shaped conveying belt 1 layout significantly reduces the space occupation, is suitable for places with limited space, improves the accuracy and efficiency of sorting through accurate RFID identification and intelligent material shifting mechanism 5, and the compact equipment layout and real-time monitoring system make the equipment more easily monitored and managed.

[0035] As shown in Figure 3 In some embodiments, the identification assembly 2 includes a U-shaped plate 201 fixed on the top of the edge of the conveying belt 1, the top of the U-shaped plate 201 is fixed with mounting plates 202 on the front and rear sides, the bottom of the mounting plate 202 is provided with an RFID reader-writer 203, and the inner side wall of the edge of the conveying belt 1 is fixed below the U-shaped plate 201. A guide plate 204 is arranged below the RFID reader-writer 203 for guiding the test paper to pass below the RFID reader-writer 203, more specifically, the U-shaped plate 201 is fixed on the top of the edge of the conveying belt 1, forming a semi-enclosed structure for protecting and supporting the RFID reader-writer 203 installed inside, the RFID reader-writer is the core component of the identification assembly 2, which communicates with the RFID tag on the test paper bag through radio waves, reads the information stored in the tag, which may include the identification of the test paper bag, subject, examination room, etc. When the test paper bag passes below the RFID reader-writer 203, the reader-writer emits electromagnetic waves to activate the RFID tag and read the data therein, and the read data is then transmitted to the main control board (mentioned in the foregoing) for processing.

[0036] As shown in Figure 4As shown, in some embodiments, the two mounting plates 202 are staggered front to back. More specifically, by staggering the mounting plates 202, the identification area of ​​the RFID reader 203 can cover a wider range, thereby improving the device's identification capability and efficiency. In actual use, the test paper bags may enter the conveyor belt 1 from different directions. The staggered mounting plate 202 design ensures that the test paper bags can be captured by the RFID reader 203 regardless of whether they enter from the front or the back. At the same time, due to the staggered arrangement of the mounting plates 202, the RFID reader 203 can scan the test paper bags from multiple angles, increasing the accuracy and reliability of identification. Even if the test paper bags experience slight displacement or rotation during movement, they can still be effectively identified.

[0037] like Figure 4 As shown, in some embodiments, the guide plate 204 is zigzag-shaped, and a connecting plate 205 is fixed between its middle portion and the bottom of the U-shaped plate 201. More specifically, the zigzag-shaped guide plate 204 can effectively disperse the pressure and friction generated during the movement of the test paper bag, reducing the risk of wear and damage to the test paper bag. At the same time, it can also guide the test paper bag to move along a predetermined path, avoiding deviation from the track or jamming. The connecting plate 205 is located between the middle portion of the guide plate 204 and the bottom of the U-shaped plate 201, acting as a bridge and support. It tightly connects the guide plate 204 and the U-shaped plate 201 together with fasteners (such as screws, nuts, etc.) to form a stable overall structure.

[0038] like Figure 3 As shown, in some embodiments, the feeding mechanism 5 includes a rotating rod 501 rotatably connected to one side of the connecting plate 4. A feeding plate 502 is fixedly mounted on the surface of the rotating rod 501 above the connecting plate 4. A driving member is provided at the bottom of the discharge hopper 3. The driving member is used to drive the feeding plate 502 to swing. The driving member includes an electric push rod 503 mounted on one side of the bottom of the discharge hopper 3. A hinge plate 504 is hinged to the piston end of the electric push rod 503. A linkage plate 505 is fixedly mounted at the bottom end of the rotating rod 501. The end of the rod 501 furthest from the rotating rod 501 is hinged to the hinge plate 504. More specifically, the electric push rod 503 provides the oscillating power for the material feeding plate 502 through the reciprocating motion of the piston end. The hinge plate 504 is an intermediate transmission component, which is hinged to the piston end of the electric push rod 503. The function of the hinge plate 504 is to convert the linear motion of the electric push rod 503 into the oscillating motion of the material feeding plate 502. The linkage plate 505 is fixed to the bottom end of the rotating rod 501 and hinged to the hinge plate 504. When the electric push rod 503 pushes the hinge plate 504, the linkage plate 505 moves accordingly, thereby driving the rotating rod 501 and the material feeding plate 502 to oscillate.

[0039] like Figure 3As shown, in some embodiments, the discharge hopper 3 gradually reduces in height from its side close to the conveying belt 1 to the other side, more specifically, by gradually reducing the height of the discharge hopper 3, the test paper bags can be made to slide out more smoothly during the discharging process by the action of gravity, reducing the problem of poor discharging caused by friction or jamming, the design of gradually reducing in height helps to disperse the accumulation pressure of the test paper bags in the discharge hopper 3, reduces the risk of blockage, and ensures the continuity and efficiency of the sorting operation.
