Description

Technical Field

[0001] The present invention relates to the technical field of composite label paper detection, and in particular to an RFID composite label paper automatic conveying detection device and a detection method. Background Art

[0002] Composite label paper is an electronic label that combines an RFID chip and an antenna with a paper substrate. Usually, the antenna and chip are laminated together, and then the prepared RFID composite label paper is pressed on a release liner. The roll of release liner is then tested. When unqualified RFID composite label paper is detected, the unqualified RFID composite label paper needs to be peeled off and replaced with qualified RFID composite label paper. This method has a complicated process and greatly reduces the manufacturing efficiency of RFID composite label paper.

[0003] In the prior art, a large number of RFID composite label paper automatic conveying detection devices are also disclosed, among which, for example, a Chinese patent application with publication number CN116374551A discloses an RFID label paper detection device and method; including a base, a slide, a conveyor belt, a mounting frame, an operating table and a paper stop; the slide includes a first slide rail and a second slide rail; the conveyor belt is connected between the first slide rail and the second slide rail; the mounting frame includes a first side panel and a second side panel, and the bottom end of the first side panel and the bottom end of the second side panel are respectively vertically arranged on the first slide rail and the second slide rail; the two ends of the operating table are respectively connected to the top end of the first side panel and the top end of the second side panel, and the upper surface of the operating table is connected to a control panel.

[0004] When it is in use, the first baffle and the second baffle move to adjust a plurality of RFID label papers to the middle position of the first channel and the middle position of the second channel respectively; the conveyor belt is driven to rotate to make a plurality of RFID label papers move towards the extension direction of the first channel and the extension direction of the second channel respectively; the information of the RFID label papers passing through the first channel and the second channel is detected respectively; if it is detected that the RFID label paper contains an RFID chip, the conveyor belt continues to convey the RFID label paper; if it is detected that there is no RFID chip on the RFID label paper, the conveyor belt stops conveying the RFID label paper, and an alarm sound is issued, and workers are reminded to deal with unqualified RFID label papers in time.

[0005] However, in the process of automatically conveying and detecting RFID label paper using the above-mentioned existing technology, there are still the following shortcomings: 1. Since the above-mentioned existing technology detects the entire roll of RFID label paper, although it can detect whether there are defective products, it is impossible to automatically remove the RFID label paper when it is detected that it is unqualified, and it is necessary to wait for manual cleaning, which increases the detection time and greatly reduces the detection efficiency.

[0006] 2. In the above-mentioned prior art, during the detection process of RFID label paper, the detection device in the first channel and the second channel cannot move synchronously with the RFID label paper on the conveyor belt, so that the detector has a short scanning time for the RFID label paper, and it cannot be ensured that the detector can scan accurately. The detection result has low accuracy and is prone to false detection.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in the prior art RFID composite label paper detection methods. Summary of the invention

[0019] S2: Conveying detection: During the rotation of the rotating shaft, the auxiliary shaft is driven to rotate synchronously and the groove wheel is driven to rotate intermittently through the toggle wheel.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-Figure 10 Embodiments of the present invention are described in detail.

[0038] The embodiment of the present application discloses an automatic conveying and detection device for RFID composite label paper. It should be noted that the automatic conveying and detection device for RFID composite label paper of the present application is mainly used in the process of automatic conveying and detection of RFID composite label paper. In terms of technical effect, it can ensure the stable transmission and accurate pasting of label paper. In particular, during the detection process, it avoids the problem of false detection caused by too short scanning time. The detector 32 and the RFID composite label paper move synchronously in a circumferential direction, which prolongs the scanning time and ensures the accuracy of the reading and writing detection of the RFID chip. Furthermore, the automatic conveying and detection device for RFID composite label paper can also automatically separate and recycle unqualified label paper, thereby improving the overall production efficiency.

[0039] Embodiment 1:

[0040] Reference Figure 1 , Figure 2 and Figure 3As shown, an automatic conveying and detecting device for RFID composite label paper comprises two bracket plates 1, two rotating shafts 11 are rotatably connected to the opposite sides of the two bracket plates 1, and the outer walls of the two rotating shafts 11 are sleeved with horizontally arranged conveyor belts 12, and a driving motor 13 is installed on any one of the bracket plates 1 through a motor seat, and a driving shaft 14 is rotatably connected to the opposite sides of the two bracket plates 1, and two circular plates 15 are rotatably sleeved on the outer wall of the driving shaft 14, and an inner sleeve ring 16 and an outer sleeve ring 17 are rotatably connected between the two circular plates 15, and the outer sleeve ring 17 is covered on the outside of the inner sleeve ring 16, and the outer sleeve ring 17 is covered on the outside of the inner sleeve ring 16. A plurality of detection components 3 are installed on the outer wall of the ring 17, a cross 18 is sleeved on the outer wall of the driving shaft 14, and the four extending ends of the cross 18 are connected to the inner wall of the inner ring 16; a negative pressure chamber 19 is formed between the outer ring 17 and the inner ring 16, an air pump 20 is installed on any one of the circular plates 15, and the air pump 20 is connected to the negative pressure chamber 19, a groove wheel 21 is sleeved on the outer wall of the driving shaft 14, an auxiliary shaft 22 is rotatably connected on the circular plate 15 close to the groove wheel 21, a toggle wheel 23 is sleeved on the outer wall of the auxiliary shaft 22, and the auxiliary shaft 22 and the rotating shaft 11 are connected by a belt drive.

[0041] In the specific implementation process, the driving motor 13 is first started, and the output shaft of the driving motor 13 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the conveyor belt 12 to convey the RFID composite label paper coated with adhesive to the bottom of the detection component 3, and then the vacuum pump 20 is started, and the vacuum pump 20 continuously extracts air in the negative pressure chamber 19, so that suction is generated at the end of the detection component 3, and the auxiliary shaft 22 is driven to rotate synchronously during the rotation of the rotating shaft 11. The auxiliary shaft 22 drives the groove wheel 21 to rotate intermittently through the toggle wheel 23, and the groove wheel 21 drives the active shaft 14, the cross 18, the detection component 3, the inner ring 16 and the outer ring 17 to move synchronously and intermittently in a circumferential direction. When the detection component 3 rotates to the bottom, the end of the detection component 3 absorbs the RFID composite label paper on the upper end of the conveyor belt 12, and then the detection component 3 detects the RFID composite label paper.

[0042] Reference Figure 3 , Figure 4 and Figure 5As shown, in order to make the detector 32 move synchronously with the RFID composite label paper and improve the scanning time, based on this, in this embodiment, a detection component 3 is provided; specifically, the detection component 3 includes a plurality of connecting tubes 31 equidistantly distributed along the circumference of the outer wall of the outer sleeve 17, and the detector 32 is installed on the side of the inner wall of the connecting tube 31 away from the axis of the outer sleeve 17 through a support frame, and the connecting tube 31 is connected to the side close to the driving shaft 14 with a linkage rod 33, and the linkage rod 33 is connected to the side close to the driving shaft 14 through the inner sleeve 16 with a trigger rod 34, and the trigger rod 34 is connected to the inner wall of the inner sleeve 16 with a reset spring 35, and the circular plate 15 close to the groove wheel 21 is installed with a controller 36 and a support plate 37 on the side opposite to the outer sleeve 17, and the support plate 37 is installed with an electric push rod 38 on the side away from the driving shaft 14, and the controller 36, the detector 32 and the electric push rod 38 are respectively electrically connected.

[0043] Furthermore, in the present embodiment, a plurality of connecting tubes 31 are provided with connecting grooves 39 on their outer walls, and an arc-shaped sealing rod 40 which is slidably docked in the connecting grooves 39 is provided on the circular plate 15 on which the supporting plate 37 is installed, and two transmission shafts 41 are rotatably connected between the two support plates 1, and the outer walls of the two transmission shafts 41 are both sleeved with bottom film rollers 42, and a receiving plate 43 is connected between the two support plates 1, and the release bottom paper which is wound together on the outer walls of the two bottom film rollers 42 can be supported toward the side close to the outer ring 17 through the receiving plate 43.

[0044] It should be noted that the detector 32 used in this embodiment is an RFID reader / writer in the prior art, which is used to read and write RFID composite label paper to ensure that the RFID composite label paper meets the detection requirements; the controller 36 used in this embodiment is a PLC controller in the prior art, which is mainly used to control the extension and retraction of the electric push rod 38. Its specific working principle will not be repeated here; the reset spring 35 always applies an elastic force to the trigger rod 34 toward the side close to the active shaft 14, so that the connecting tube 31 can be reset under the elastic force of the reset spring 35 after moving out of the negative pressure chamber 19; in addition, the length of the arc-shaped sealing rod 40 is equal to the length between two adjacent connecting grooves 39.

[0045] During the specific implementation process, the outer ring 17 and the inner ring 16 drive multiple connecting tubes 31 to move synchronously in the circumferential movement. When the connecting tube 31 rotates to the bottom, the negative pressure of the negative pressure chamber 19 causes the air in the connecting tube 31 to enter the negative pressure chamber 19 from the connecting groove 39, thereby generating suction at the bottom of the connecting tube 31. The connecting tube 31 adsorbs the RFID composite label paper at the upper end of the conveyor belt 12 to the bottom of the connecting tube 31, and then the detector 32 in the connecting tube 31 scans the RFID composite label paper to detect whether the RFID composite label paper can be read and written. At the same time, the synchronous circumferential movement of the detector 32 and the RFID composite label paper increases the scanning time of the detector 32 for the RFID composite label paper, thereby avoiding the problem of false detection or missed detection due to short scanning time, and greatly improving the accuracy of the detection result.

[0046] At the same time, the outer ring 17 and the inner ring 16 drive the connecting tube 31 and the RFID composite label paper to synchronously perform clockwise circumferential motion. When the connecting tube 31 rotates to the side close to the receiving plate 43, after the controller 36 receives the signal that the detector 32 has detected qualified, the controller 36 controls the telescopic end of the electric push rod 38 to extend and push the connecting tube 31 to move away from the active shaft 14. The connecting tube 31 drives the linkage rod 33 and the trigger rod 34 to synchronously move toward the side close to the receiving plate 43, and the reset spring 35 shrinks adaptively, so that the connecting tube 31 drives the connecting groove 39 to gradually move out of the negative pressure chamber 19. When the connecting groove 39 is completely moved out of the negative pressure chamber 19, the connecting tube 31 is no longer connected to the negative pressure chamber 19, and the connecting tube 31 is no longer connected to the negative pressure chamber 19. The connecting tube 31 no longer applies suction to the RFID composite label paper, and at the same time, the RFID composite label paper moves synchronously with the connecting tube 31 and sticks to the release base paper, thereby preventing the suction of the connecting tube 31 from peeling the RFID composite label paper off the release base paper when the RFID composite label paper is stuck to the release base paper; then the controller 36 controls the telescopic end of the electric push rod 38 to retract, the reset spring 35 adaptively rebounds and drives the trigger rod 34 to move synchronously, the trigger rod 34 drives the linkage rod 33 and the connecting tube 31 to reset, the connecting groove 39 is connected to the negative pressure chamber 19 again, and the end of the connecting tube 31 away from the active shaft 14 generates suction again, thereby facilitating the subsequent adsorption and transportation of the RFID composite label paper.

[0047] When the detector 32 cannot read or write the RFID composite label paper during scanning of the RFID composite label paper, the controller 36 receives the signal from the detector 32 that the RFID composite label paper has failed the detection, and the controller 36 no longer controls the electric push rod 38 to start, so that the connecting tube 31 no longer moves toward the side close to the receiving plate 43, and then the connecting tube 31 drives the unqualified RFID composite label paper to move circumferentially to the upper end, and moves again to the side away from the receiving plate 43. During the rotation of the connecting tube 31, the connecting groove 39 moves to the side close to the arc-shaped sealing rod 40, and the arc-shaped sealing rod 40 seals the connecting groove 39, so that the connecting tube 31 is no longer connected to the negative pressure chamber 19, and the connecting tube 31 no longer adsorbs the RFID composite label paper, thereby releasing the unqualified RFID composite label paper.

[0048] Reference Figure 6 , Figure 7 and Figure 8 As shown, in order to automatically replace and recycle the unqualified RFID composite label paper, based on this, in the present embodiment, a transmission shaft 51 is rotatably connected to any one of the bracket plates 1, and a transmission gear 52 is sleeved on the outer wall of the transmission shaft 51. A sliding groove 53 is provided on the bracket plate 1, and a sliding block 54 is slidably connected in the sliding groove 53. A toggle rod 55 corresponding to the sliding block 54 is installed on the connecting pipe 31, and a supporting spring 56 is connected between the sliding block 54 and the sliding groove 53. A rotating shaft 57 is rotatably connected to the bracket plate 1 on which the sliding block 54 is installed, and a linkage gear 58 meshing with the transmission gear 52 is sleeved on the outer wall of the rotating shaft 57. The rotating shaft 57 is connected to the transmission shaft 41 near the bottom through a belt drive, and the transmission shaft 51 is connected to the rotating shaft 11 through an elastic belt. A receiving bucket 59 is connected to the opposite sides of the two bracket plates 1, and a scraper 60 is hinged on the side of the receiving bucket 59 near the outer ring 17, and a torsion spring (not shown in the figure) is connected to the hinge between the scraper 60 and the receiving bucket 59.

[0049] It should be noted that the support spring 56 always applies an elastic force to the sliding block 54 away from the receiving plate 43, so that the sliding block 54 can quickly reset after losing the push of the toggle rod 55; in addition, the torsion spring always applies an upward rotational torsion force to the scraper 60, so that the scraper 60 can automatically reset after losing the squeezing of the connecting tube 31.

[0050] In the specific implementation process, the connecting pipe 31 drives the toggle rod 55 to synchronously intermittently move in the circumferential direction during its movement. When the connecting pipe 31 moves toward the side close to the receiving plate 43, the toggle rod 55 drives the sliding block 54 to synchronously move along the sliding groove 53 toward the side close to the receiving plate 43, and the support spring 56 shrinks adaptively. The sliding block 54 drives the transmission shaft 51 and the transmission gear 52 to synchronously move toward the side close to the linkage gear 58; then the transmission gear 52 and the linkage gear 58 are meshed, and the transmission shaft 51 is driven to rotate synchronously during the rotation of the rotating shaft 11, and the transmission shaft 51 drives the transmission gear 52 to rotate, and the transmission gear 52 drives the linkage gear 58 8 rotates in the opposite direction to the rotating shaft 57, the rotating shaft 57 drives the transmission shaft 41 to rotate synchronously, and the transmission shaft 41 drives the bottom film roller 42 to rotate synchronously, so that the RFID composite label paper that has been pasted on the release paper is wound on the bottom film roller 42 below, and the release paper without the RFID composite label paper is transferred to the receiving plate 43, so that when the connecting tube 31 drives the qualified RFID composite label paper to be pasted on the release paper, it is automatically wound. In addition, the bottom film roller 42 drives the release paper on its outer wall and the outer ring 17 to rotate synchronously and intermittently, ensuring that the RFID composite label paper is pasted on the release paper in sequence.

[0051] Subsequently, when the connecting tube 31 moves away from the receiving plate 43, the connecting tube 31 drives the toggle rod 55 to move synchronously, and the sliding block 54 is reset under the rebound action of the supporting spring 56. The sliding block 54 drives the transmission shaft 51 and the transmission gear 52 to move synchronously away from the linkage gear 58, and the transmission gear 52 and the linkage gear 58 no longer cooperate, thereby realizing intermittent winding of the RFID composite label paper and avoiding excessive gaps between multiple RFID composite label papers.

[0052] When the unqualified RFID composite label paper rotates with the connecting tube 31 to the side away from the receiving plate 43, the connecting tube 31 loses its suction, and then the RFID composite label falls into the receiving bucket 59 along the scraper 60. When the connecting tube 31 moves downward in a circumferential direction, the connecting tube 31 applies downward pressure to the scraper 60, and the scraper 60 adaptively rotates downward along the hinge between it and the receiving bucket 59, and the torsion spring adaptively twists. At the same time, the scraper 60 scrapes the end of the connecting tube 31 to avoid negative pressure in the connecting tube 31 after the connecting groove 39 is sealed by the arc-shaped sealing rod 40, so that the RFID composite label paper cannot fall under the action of its own gravity, thereby realizing the recycling of unqualified RFID composite label paper.

[0053] Embodiment 2:

[0054] Reference Fig. 9 and Fig.10As shown, on the basis of Example 1, in order to avoid the RFID composite label paper from tilting when being adsorbed due to the large distance between the RFID composite label paper and the connecting tube 31, based on this, in this embodiment, a telescopic tube 71 is slidably connected in the connecting tube 31, and a top spring 72 is connected between the telescopic tube 71 and the connecting tube 31. The toggle rod 55 is located on the side of the telescopic tube 71 close to the sliding block 54, and a toggle shaft 73 is rotatably connected on the bracket plate 1 close to the toggle rod 55. The outer wall of the toggle shaft 73 is sleeved with an extrusion rod 74, and the side of the extrusion rod 74 away from the toggle shaft 73 is gradually inclined toward the side away from the extrusion rod 74, and the toggle shaft 73 and the rotating shaft 11 are connected by a belt drive.

[0055] It should be noted that the top balance spring 72 always applies a pulling force to the telescopic tube 71 toward the side close to the driving shaft 14, so that the telescopic tube 71 can be quickly reset after absorbing the RFID composite label paper.

[0056] In the specific implementation process, when the connecting tube 31 rotates to the bottom, the transmission shaft 51 drives the toggle shaft 73 to rotate synchronously, and the toggle shaft 73 drives the extrusion rod 74 to move synchronously in the circumferential direction. When the extrusion rod 74 rotates to the side close to the connecting tube 31, the inclined surface of the extrusion rod 74 contacts the toggle rod 55, and the toggle rod 55 moves downward under the extrusion of the inclined surface of the extrusion rod 74. The toggle rod 55 drives the telescopic tube 71 to move downward synchronously along the connecting tube 31, and the top spring 72 is adaptively extended and retracted. Then the telescopic tube 71 adsorbs the RFID composite label paper at the upper end of the conveyor belt 12, and detects the RFID composite label through the detector 32. When the toggle shaft 73 drives the squeezing rod 74 to move away from the toggle rod 55, after the toggle rod 55 loses the limit of the squeezing rod 74, the toggle rod 55 moves into the connecting tube 31 under the action of the rebound of the top spring 72, so that the telescopic tube 71 is reset to avoid the RFID composite label paper from tilting when being adsorbed by the connecting tube 31 due to the large distance between the connecting tube 31 and the conveyor belt 12. By pressing down the telescopic tube 71, it can ensure that the RFID composite label paper is accurately adsorbed by the telescopic tube 71, so that the detector 32 can fully scan the RFID composite label paper, thereby increasing the accuracy of detection.

[0057] In addition, the present invention also provides an automatic conveying and detection method for RFID composite label paper, comprising the following steps: S1, automatic conveying: first start the driving motor 13, the output shaft of the driving motor 13 drives the rotating shaft 11 to rotate, the rotating shaft 11 drives the conveyor belt 12 to convey the RFID composite label paper coated with adhesive to the bottom of the detection component 3, and then start the vacuum pump 20, the vacuum pump 20 continuously evacuates the negative pressure chamber 19, so that suction is generated at the end of the detection component 3, and during the rotation of the rotating shaft 11, the auxiliary shaft 22 is driven to rotate synchronously, the auxiliary shaft 22 drives the groove wheel 21 to rotate intermittently through the toggle wheel 23, and the groove wheel 21 drives the driving shaft 14, the cross 18, the inner ring 16 and the outer ring 17 to move synchronously and intermittently circumferentially During the circumferential movement of the outer ring 17 and the inner ring 16, multiple connecting tubes 31 are driven to move synchronously. When the connecting tube 31 rotates to the bottom, the negative pressure of the negative pressure chamber 19 causes the air in the connecting tube 31 to enter the negative pressure chamber 19 from the connecting groove 39, thereby generating suction at the bottom of the connecting tube 31. The connecting tube 31 adsorbs the RFID composite label paper at the upper end of the conveyor belt 12 to the bottom of the connecting tube 31, and then the detector 32 in the connecting tube 31 scans the RFID composite label paper to detect whether the RFID composite label paper can be read and written. At the same time, the synchronous circumferential movement of the detector 32 and the RFID composite label paper increases the scanning time of the detector 32 for the RFID composite label paper, thereby avoiding false detection due to short scanning time.

[0058] S2. Conveying detection: At the same time, the outer ring 17 and the inner ring 16 drive the connecting tube 31 and the RFID composite label paper to synchronously move clockwise. When the connecting tube 31 rotates to the side close to the receiving plate 43, after the controller 36 receives the signal that the detector 32 has passed the detection, the controller 36 controls the telescopic end of the electric push rod 38 to extend and push the connecting tube 31 to move away from the active shaft 14. The connecting tube 31 drives the linkage rod 33 and the trigger rod 34 to synchronously move toward the side close to the receiving plate 43. The reset spring 35 shrinks adaptively, so that the connecting tube 31 drives the connecting groove 39 to gradually move out of the negative pressure chamber 19. When the connecting groove 39 is completely moved out of the negative pressure chamber 19, the connecting tube 31 is no longer connected to the negative pressure chamber 19. The connecting tube 31 is connected, and the connecting tube 31 no longer applies suction to the RFID composite label paper. At the same time, the RFID composite label paper moves synchronously with the connecting tube 31 and sticks to the release base paper, thereby preventing the suction of the connecting tube 31 from peeling off the RFID composite label paper from the release base paper when the RFID composite label paper is stuck to the release base paper; then the controller 36 controls the telescopic end of the electric push rod 38 to retract, the reset spring 35 adaptively rebounds and drives the trigger rod 34 to move synchronously, the trigger rod 34 drives the linkage rod 33 and the connecting tube 31 to reset, and the connecting groove 39 is connected to the negative pressure chamber 19 again, and the connecting tube 31 generates suction again at the end away from the active shaft 14, thereby facilitating the subsequent adsorption and transportation of the RFID composite label paper.

[0059] When the detector 32 cannot read or write the RFID composite label paper during scanning of the RFID composite label paper, the controller 36 receives the signal from the detector 32 that the RFID composite label paper has failed the detection, and the controller 36 no longer controls the electric push rod 38 to start, so that the connecting tube 31 no longer moves toward the side close to the receiving plate 43, and then the connecting tube 31 drives the unqualified RFID composite label paper to move circumferentially to the upper end, and moves again to the side away from the receiving plate 43. During the rotation of the connecting tube 31, the connecting groove 39 moves to the side close to the arc-shaped sealing rod 40, and the arc-shaped sealing rod 40 seals the connecting groove 39, so that the connecting tube 31 is no longer connected to the negative pressure chamber 19, and the connecting tube 31 no longer adsorbs the RFID composite label paper, thereby releasing the unqualified RFID composite label paper.

[0060] S3, automatic replacement: During the movement of the connecting tube 31, the toggle rod 55 is driven to synchronously intermittently move in the circumferential direction. When the connecting tube 31 moves toward the side close to the receiving plate 43, the toggle rod 55 drives the sliding block 54 to synchronously move along the sliding groove 53 toward the side close to the receiving plate 43, and the support spring 56 shrinks adaptively. The sliding block 54 drives the transmission shaft 51 and the transmission gear 52 to synchronously move toward the side close to the linkage gear 58; then the transmission gear 52 and the linkage gear 58 are meshed, and the rotation shaft 11 drives the transmission shaft 51 to rotate synchronously during rotation, the transmission shaft 51 drives the transmission gear 52 to rotate, and the transmission gear 52 drives the linkage gear 58 The rotating shaft 57 rotates in the opposite direction to the rotating shaft 57, and the rotating shaft 57 drives the transmission shaft 41 to rotate synchronously, and the transmission shaft 41 drives the bottom film roller 42 to rotate synchronously, so that the RFID composite label paper that has been pasted on the release paper is wound on the bottom film roller 42 below, and the release paper without the RFID composite label paper is transferred to the receiving plate 43, so that when the connecting tube 31 drives the qualified RFID composite label paper to be pasted on the release paper, it is automatically wound. In addition, the bottom film roller 42 drives the release paper on its outer wall and the outer ring 17 to rotate synchronously and intermittently, ensuring that the RFID composite label paper is pasted on the release paper in sequence.

[0061] Subsequently, when the connecting tube 31 moves away from the receiving plate 43, the connecting tube 31 drives the toggle rod 55 to move synchronously, and the sliding block 54 is reset under the rebound action of the supporting spring 56. The sliding block 54 drives the transmission shaft 51 and the transmission gear 52 to move synchronously away from the linkage gear 58, and the transmission gear 52 and the linkage gear 58 no longer cooperate, thereby realizing intermittent winding of the RFID composite label paper and avoiding excessive gaps between multiple RFID composite label papers.

[0062] When the unqualified RFID composite label paper rotates with the connecting tube 31 to the side away from the receiving plate 43, the connecting tube 31 loses its suction, and then the RFID composite label falls into the receiving bucket 59 along the scraper 60. When the connecting tube 31 moves downward in a circumferential direction, the connecting tube 31 applies downward pressure to the scraper 60, and the scraper 60 adaptively rotates downward along the hinge between it and the receiving bucket 59, and the torsion spring adaptively twists. At the same time, the scraper 60 scrapes the end of the connecting tube 31 to avoid negative pressure in the connecting tube 31 after the connecting groove 39 is sealed by the arc-shaped sealing rod 40, so that the RFID composite label paper cannot fall under the action of its own gravity, thereby realizing the recycling of unqualified RFID composite label paper.

[0063] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
