[0008] Furthermore, connection grooves are provided on both sides of the top surface of the detection frame corresponding to the first door panel and the second door panel, and the inner side surfaces of the connection grooves are fixedly connected to distance sensors.

[0009] Furthermore, two fixed seats are fixedly connected to the top surface of the detection frame corresponding to the second door panel, the inner side surfaces of the fixed seats are slidably connected to the sliding rod, a damping is arranged between the inner side surfaces of the fixed seats and the side surfaces of the sliding rod, the inner side surfaces of the fixed seats are fixedly connected to two springs fixedly connected to the inner side surfaces of the sliding rod, one end of the sliding rod located outside the fixed seat is fixedly connected to a sponge cover, and the side surface of the sponge cover contacts the top of the two side surfaces of the adjacent door panel.

[0010] Furthermore, a connecting rope is fixedly connected to the inner side of the sliding rod, and the connecting rope passes through the inside of the second spring and extends to the outside of the fixing seat. One end of the connecting rope outside the fixing seat is fixedly connected to a fixing ring, and the side of the fixing ring is fixedly connected to the top of a side of an adjacent door panel.

[0011] Furthermore, the top surface of the detection frame is fixedly connected to the limit frame corresponding to the connecting rope, and the two connecting ropes pass through the inside of the limit frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. An RFID reader is fixedly connected to the detection frame, and an RFID tag can be set on the hat. In this way, after the hats with RFID tags are packed and sealed, the packaging box can be transported by a belt conveyor, so that the packaging box passes through the inside of the detection frame. When the packaging box passes through the RFID reader, the RFID tag on the hat can be read by the RFID reader, and the RFID tag information is read by the RFID reader.

At this time, the information detected by the distance sensor will change. Then the roller conveyor can be operated for a certain period of time. After most of the package boxes are conveyed to the belt conveyor, the roller conveyor stops conveying the package boxes. Then the belt conveyor can continue to convey the package boxes to the RFID reader. In this way, two package boxes can be avoided from existing in the detection frame at the same time, which affects the reading of the RFID tag by the RFID reader. At the end of the reading, the package box squeezes door panel 2, which changes the information detected by the distance sensor on door panel 2. At this time, the roller conveyor is started to continue conveying the next package box. This avoids two package boxes passing through the RFID reader closely, which is conducive to the accurate reading of the RFID reader. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 In an embodiment of the utility model, an automatic label detection mechanism includes a detection frame 2, a belt conveyor 1 is fixedly connected to the bottom surface of the detection frame 2, a support frame 11 is fixedly connected to the bottom surface of the belt conveyor 1, an RFID reader 5 is fixedly connected to the top surface and two inner side surfaces of the detection frame 2, two door panels 21 are arranged on one side of the inner side surface of the belt conveyor 1, the side of the door panel 21 located inside the detection frame 2 is rotatably connected to the inner side surface of the detection frame 2 through a hinge, two door panels 22 are arranged on the other side of the inner side surface of the belt conveyor 1, the side of the door panel 22 located outside the detection frame 2 is rotatably connected to the side surface of the detection frame 2 through a hinge, a roller conveyor 3 is arranged on one side of the belt conveyor 1 corresponding to the door panel 21, and a label printer 4 is attached to the top surface of the detection frame 2.

[0023] Specifically, a total of four RFID readers 5 are arranged inside the detection frame 2, one RFID reader 5 is arranged on each of the two inner walls of the detection frame 2, and two RFID readers 5 are arranged on the inner top surface of the detection frame 2. An RFID tag is arranged on the hat. After the hat with the RFID tag is loaded into a packaging box and sealed, the packaging box can be placed on the roller conveyor 3, and the packaging box can be conveyed to the belt conveyor 1 by the roller conveyor 3. After the packaging box moves to the belt conveyor 1, the packaging box can continue to be conveyed by the belt conveyor 1. The packaging box can squeeze the door panel 21 to make the door panel 21 rotate toward the inside of the detection frame 2, and then the packaging box can pass between the two door panels 21 to enter the inside of the detection frame 2. The packaging box is moved inside the detection frame 2 by the belt conveyor 1. When the packaging box passes through the RFID reader 5, the hat can be read by the RFID reader 5 The RFID tag on the box is read, and the information stored in the RFID tag is read by the RFID reader 5. According to the amount of information read by the RFID reader 5, the number and type of hats in the packaging box are understood, and automatic detection of hats with RFID tags is realized. There is no need for manual counting, which avoids manual counting errors, and is beneficial to reducing the burden on staff and improving the packing speed. During the detection, the tag information read by the RFID reader 5 can be received by the matching computer, and then a paper label with the number and type information of hats can be printed by the label printer 4. The paper label can be attached to the packaging box for subsequent warehousing and delivery. After the packaging box passes through the RFID reader 5, the packaging box can squeeze the door panel 22, and then pass through the two door panels 22 to move out of the interior of the detection frame 2, and then the RFID tag in the next packaging box can be read.

[0024] Embodiment 1

[0025] like Figure 3 As shown, in the present embodiment, a connecting block 23 is fixedly connected to the side of door panel 1 21 and the top of the side of door panel 22, the connecting block 23 on door panel 1 21 is outside the detection frame 2, and the connecting block 23 on door panel 22 is inside the detection frame 2, a spring 25 is fixedly connected to the side of the connecting block 23, and the ends of two adjacent springs 25 that are away from each other are fixedly connected to connecting blocks 24, the side of the connecting block 24 on one side of door panel 21 is fixedly connected to the outer side of the detection frame 2, and the side of the connecting block 24 on one side of door panel 22 is fixedly connected to the inner side of the detection frame 2.

[0026] In a specific implementation, the connecting block 1 23, the connecting block 24 and the spring 1 25 on one side of the door panel 1 21 are all located outside the detection frame 2, while the connecting block 1 23, the connecting block 24 and the spring 1 25 on one side of the door panel 22 are all located inside the detection frame 2, the connecting block 1 23 is located between two adjacent springs 1 25, and the connecting block 1 23 and the spring 1 25 are both located between two adjacent connecting blocks 2 24. When the packaging box squeezes the door panel 1 21 into the detection frame 2, the door panel 1 21 rotates to bend and stretch the adjacent springs 1 25. After the door panel 1 21 is separated from the packaging box, Under the action of the adjacent spring 1 25, the door panel 1 21 can be rotated in the opposite direction to the original angle, so that the door panel 1 21 continues to remain in a closed state. After the RFID reader 5 completes the detection of the RFID tag inside the package box, the belt conveyor 1 continues to convey the package box, so that the package box squeezes the door panel 22, and the two door panels 22 rotate toward the outside of the detection frame 2. After the package box passes between the two door panels 22 and moves to the outside of the detection frame 2, under the action of the adjacent spring 1 25, the door panel 22 can be rotated to the original position, so that the door panel 22 continues to remain in a closed state.

[0027] like Figure 4 As shown, in this embodiment, connecting grooves 26 are provided on both sides of the inner top surface of the detection frame 2 corresponding to the first door panel 21 and the second door panel 22 , and the inner side of the connecting groove 26 is fixedly connected to the distance sensor 6 .

[0028] In a specific implementation, the door panel 1 21 and the door panel 22 can block the adjacent distance sensor 6. One distance sensor 6 is located on the side where the two door panels 1 21 are close to each other, and the other distance sensor 6 is located on the side where the two door panels 22 are close to each other. In this way, when the door panel 1 21 and the door panel 2 22 rotate, the door panel 1 21 and the door panel 2 22 can quickly stagger with the adjacent distance sensor 6. When the roller conveyor 3 conveys the packaging box, so that the packaging box squeezes the door panel 1 21 and enters the detection frame 2, the door panel 1 21 will rotate toward the detection frame 2 and stagger with the adjacent distance sensor 6. At this time, the distance information detected by the distance sensor 6 will change. After the matching controller receives the change in the detection information of the distance sensor 6, the roller conveyor 3 can continue to run for a certain period of time to transport most of the packaging boxes to the belt conveyor. After the machine 1 is put on, the roller conveyor 3 is stopped, and the belt conveyor 1 can continue to convey the packaging box to the inside of the detection frame 2. By stopping the roller conveyor 3, when two packaging boxes are placed closely together, the two packaging boxes can be prevented from entering the detection frame 2 closely, so as to avoid affecting the reading of the RFID tag by the RFID reader 5. At the end of the reading, the packaging box can squeeze the door panel 22, so that the door panel 22 rotates toward the outside of the detection frame 2 and staggered with the adjacent distance sensor 6. At this time, the information detected by the distance sensor 6 at the top of the door panel 22 will change. Then the roller conveyor 3 is started to continue to convey the next packaging box, so as to avoid the situation where two packaging boxes pass through the RFID reader 5 closely. In one reading process, only one packaging box is located inside the detection frame 2, which is conducive to the accurate reading of the RFID reader 5.

[0029] Embodiment 2

[0030] Based on the first embodiment, Figure 5 As shown, in the present embodiment, the inner top surface of the detection frame 2 is fixedly connected to the door panel 22 with two fixing seats 7, the inner side surface of the fixing seat 7 is slidably connected to the sliding rod 71, a damping is arranged between the inner side surface of the fixing seat 7 and the side surface of the sliding rod 71, the inner side surface of the fixing seat 7 is fixedly connected to the spring 2 72 fixedly connected to the inner side surface of the sliding rod 71, the end of the sliding rod 71 located outside the fixing seat 7 is fixedly connected to the sponge cover 73, and the side surface of the sponge cover 73 contacts the top of the side surface of the adjacent door panel 22, the inner side surface of the sliding rod 71 is fixedly connected to the connecting rope 74, the connecting rope 74 passes through the inside of the spring 2 72 and extends to the outside of the fixing seat 7, the end of the connecting rope 74 located outside the fixing seat 7 is fixedly connected to the fixing ring 9, and the side surface of the fixing ring 9 is fixedly connected to the top of the side surface of the adjacent door panel 21, the inner top surface of the detection frame 2 is fixedly connected to the limiting frame 8 with the connecting rope 74, and the two connecting ropes 74 pass through the inside of the limiting frame 8.

[0031] When the packing box passes through the two door panels 22 and moves out of the detection frame 2, under the action of the adjacent spring 1 25, the door panel 22 is rotated in the opposite direction to its original position, and the door panel 22 will contact the sponge sleeve 73 at the end of the sliding rod 71, and the sponge sleeve 73 can buffer the door panel 22. At the same time, the spring 272 and the damping can provide resistance to the movement of the sliding rod 71, thereby providing buffering for the door panel 22 through the sliding rod 71, so that the door panel 22 can be quickly stabilized, and the door panel 22 can be prevented from swinging back and forth and causing great interference to the detection of the distance sensor 6. When the packing box passes through the two door panels 21 and enters the detection frame 2, under the action of the adjacent spring 1 25, the door panel 21 is rotated in the opposite direction to its original position. The door panel 21 can pull the sliding rod 71 to move through the connecting rope 74, and the spring 272 and the damping can provide resistance to the movement of the sliding rod 71, thereby providing buffering for the door panel 21 through the sliding rod 71, so that the door panel 21 can be quickly stabilized.

[0032] After the distance information detected by the distance sensor 6 at the top of the door panel 21 changes once, the controller stops receiving the detection information of the distance sensor 6 at the top of the door panel 21 until the distance information detected by the distance sensor 6 at the top of the door panel 22 changes once, and then the controller starts receiving the detection information of the distance sensor 6 at the top of the door panel 21 again. After the distance information detected by the distance sensor 6 at the top of the door panel 22 changes once, the controller stops receiving the detection information of the distance sensor 6 at the top of the door panel 22 until the distance information detected by the distance sensor 6 at the top of the door panel 21 changes once, and then the controller starts receiving the detection information of the distance sensor 6 at the top of the door panel 22 again. This can prevent the door panel 1 21 and the door panel 22 from rotating in the opposite direction to their original positions. When the door panel 1 21 and the door panel 22 swing, it will cause great interference to the controller in controlling the start and stop of the roller conveyor 3.
