Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production, and in particular to an integrated device for roll scanning and diameter detection. Background Technology

[0002] In the paper roll conveyor line of a corrugated cardboard production workshop, RFID (Radio Frequency Identification Chip) scanning and diameter detection of paper rolls are crucial for ensuring the efficient operation of subsequent processing. Existing technologies have operational flaws in both, resulting in paper roll processing efficiency and detection accuracy that fail to meet production demands. Specifically: when scanning the RFID chip on a paper roll, because the chip's position at the front or back of the roll cannot be determined in advance, one end of the roll must be scanned first. If the scan fails, the roll must be conveyed forward a certain distance before scanning the other end. This process requires the conveyor equipment to start and stop twice, and the scanning device to repeat the scan, severely reducing scanning efficiency. When detecting the paper roll diameter, a non-contact measurement method using a distance measurement sensor positioned directly above the center of the roll is employed. This method is highly dependent on the surface condition of the paper roll, easily affected by surface reflectivity and flatness, making it difficult to accurately obtain roll diameter data. Therefore, there is an urgent need for an integrated paper roll scanning and diameter detection device to solve the problems of low RFID chip scanning efficiency and poor paper roll diameter detection accuracy in existing technologies, achieving efficient and accurate paper roll processing to meet the needs of modern workshop production.

Detailed Implementation

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

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, top, bottom) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] In this embodiment of the invention, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0027] See Figures 1-2 This utility model provides an integrated device 10 for scanning and detecting the diameter of a roll of material. The integrated device 10 for scanning and detecting the diameter of a roll of material includes, for example, a support base 100, a lifting mechanism 200, a scanning structure 400, a contact diameter detection structure 500, and a controller (not shown).

[0028] The support base 100 is, for example, a vertical structure. In this embodiment, the support base 100 may be made of aluminum alloy, which has sufficient structural strength to stably support the operation of the lifting mechanism 200 and other components. Its height can be designed to be adapted to the height of the workshop's roll conveyor line. A guide rail may be provided on one side of the support base 100 to provide a guiding foundation for the reciprocating motion of the lifting mechanism 200.

[0029] Specifically, the lifting mechanism 200 is, for example, located on one side of the support base 100 and movably connected to the support base 100. The lifting mechanism 200 can reciprocate along the height direction of the support base 100. In this embodiment, the lifting mechanism 200 can be, for example, a synchronous belt lifting assembly, including a lifting frame, a synchronous pulley, a synchronous belt, and a drive motor. The lifting frame slides along a guide rail on the support base 100, and the drive motor drives the synchronous pulley to rotate, thereby driving the lifting frame to move along the height direction via the synchronous belt.

[0030] Specifically, the scanning structure 400 includes, for example, a crossbeam 401 and a first scanning element 410 and a second scanning element 420 movably disposed at both ends of the crossbeam 401. The crossbeam 401 is fixedly connected to the lifting mechanism 200, and the first scanning element 410 and the second scanning element 420 can move along... Figure 1 The third direction shown is the extension direction of the crossbeam 401. The first scanning element 410 and the second scanning element 420 move in opposite directions or in opposite directions along the third direction, which can adapt to the scanning requirements of rolls of different lengths. In this embodiment, the crossbeam 401 can be, for example, a rectangular metal rod, which is fixed to the lifting frame of the lifting mechanism 200 by bolts in the middle; the first scanning element 410 and the second scanning element 420 can be, for example, RFID scanning probes, both of which are slidably engaged with the crossbeam 401 through a sliding structure, and are equipped with a drive motor, which can drive the scanning probe to move along the crossbeam 401 to adapt to the scanning requirements of rolls of different lengths.

[0031] Specifically, the contact diameter detection structure 500 is, for example, fixedly connected to the lifting mechanism 200, and is located between the first scanning element 410 and the second scanning element 420. In this embodiment, the contact diameter detection structure 500 may include, for example, a fixed base and a contact detection end. The fixed base is fixed to the lifting mechanism 200 by a bracket, and the contact detection end is, for example, located on the side of the fixed base facing the roll material. When the device is in its initial state, the distance between the contact detection end and the preset detection reference plane of the roll material conveying line is the initial height, which is a known fixed value and has been precisely calibrated. Since the roll material is cylindrical, there is an angular difference between its outer circle and the conveying plane. To eliminate the measurement error caused by this difference, the controller has a built-in compensation parameter library for different roll material diameters. When the lifting mechanism 200 drives the contact diameter detection structure 500 to descend, and the contact detection end contacts the outer circle of the coil, the corresponding sensing unit triggers a contact signal and transmits it to the controller. The controller immediately records the actual descent height of the lifting mechanism 200, combines the difference between the initial height and the actual descent height, and then calls the compensation parameters of the corresponding diameter range for correction, finally accurately calculating the actual diameter of the coil to ensure detection accuracy.

[0032] Specifically, the controller is electrically connected to, for example, the lifting mechanism 200, the first scanning element 410, the second scanning element 420, and the contact diameter detection structure 500. In this embodiment, the controller may be, for example, a PLC controller, which is electrically connected to the drive motor of the lifting mechanism 200, the drive motors of the first scanning element 410 and the second scanning element 420, and the contact detection end of the contact diameter detection structure 500, respectively. It can receive detection signals and send control commands to realize the coordinated operation of each component.

[0033] The lifting mechanism 200 has a first position and a second position relative to the support base 100. When the lifting mechanism 200 is in the first position, the contact diameter detection structure 500 is in contact with the outer circle of the coil. When the lifting mechanism 200 is in the second position, the first scanning element 410 and the second scanning element 420 scan the two ends of the coil respectively.

[0034] In this embodiment, the specific working principle of the integrated device 10 for coil scanning and diameter detection is as follows: After the coil is conveyed to the detection position, the controller first controls the lifting mechanism 200 to operate, driving the lifting frame to descend towards the coil; when the contact detection end of the contact diameter detection structure 500 contacts the outer circle of the coil, the contact detection end of the contact diameter detection structure 500 generates contact feedback and transmits the feedback signal to the controller. The controller immediately records the actual descent height of the lifting mechanism 200, and calculates the coil diameter detection by the difference between the preset initial height and the actual descent height; diameter After the inspection is completed, the controller controls the lifting mechanism 200 to continue descending to the second position, so that the first scanning element 410 and the second scanning element 420 correspond to the center position of the roll (i.e., the position for scanning and reading the chip). The contact diameter detection structure 500 remains in contact with the outer circle of the roll as the lifting frame descends. Subsequently, the controller controls the first scanning element 410 and the second scanning element 420 to move along the crossbeam 401 to the positions corresponding to both ends of the roll, and synchronously starts the scanning operation to quickly read the RFID chip information in the center of the paper core tube. After the scanning is completed, all components are reset under the control of the controller, waiting for the next roll inspection. Among them, RFID (Radio Frequency Identification Chip) is a non-contact automatic identification technology carrier that automatically identifies target objects and obtains relevant data through radio frequency signals. In this device, it is used to store roll information for the scanning element to read in order to realize the identification of the roll and other information.

[0035] Therefore, the integrated roll scanning and diameter detection device 10 provided in this embodiment, by setting up a support base 100, a lifting mechanism 200, a scanning structure 400, a contact diameter detection structure 500 and a controller, realizes the continuous operation of roll diameter detection and RFID scanning through integrated design and the coordinated cooperation of each component; it solves the problem of poor accuracy of traditional non-contact measurement by contact detection, and avoids roll movement and repeated scanning by synchronous scanning at both ends, thus solving the defect of low scanning efficiency. At the same time, it adapts to the detection needs of rolls of different lengths, significantly improving the efficiency and accuracy of roll processing, and meeting the modern production needs of corrugated cardboard workshops.

[0036] See Figure 2In this embodiment of the present invention, the scanning structure 400 further includes, for example, a first longitudinal beam 430 and a second longitudinal beam 440. Specifically, one end of the first longitudinal beam 430 is movably connected to the crossbeam 401, and the other end is connected to the first scanning element 410. The first longitudinal beam 430 can reciprocate along the crossbeam 401. In this embodiment, the first longitudinal beam 430 can be, for example, a rectangular metal rod with good structural rigidity. Its length can be set according to the installation requirements of the scanning element and the actual scanning scenario. Its end near the crossbeam 401 is, for example, movably engaged with the crossbeam 401 through a sliding structure, and its end away from the crossbeam 401 is, for example, fixed to the first scanning element 410 through bolts, ensuring a stable connection that is not easily loosened. Specifically, the second longitudinal beam 440 and the first longitudinal beam 430 are, for example, symmetrical structures with the same material and dimensions. A drive motor is provided between the sliding structure and the crossbeam 401, for example. This drive motor is electrically connected to the controller and can receive commands from the controller to drive the first longitudinal beam 430 and the second longitudinal beam 440 to move synchronously or independently along the crossbeam 401. This embodiment, by setting a first longitudinal beam 430 and a second longitudinal beam 440, can provide stable installation support for the first scanning component 410 and the second scanning component 420, avoiding positional displacement caused by vibration during scanning. Furthermore, by moving the longitudinal beam along the crossbeam 401, the scanning component can be precisely adjusted to adjust the alignment distance with both ends of the roll material, adapting to the scanning needs of roll materials of different lengths, and further improving the accuracy and efficiency of RFID chip scanning.

[0037] See Figure 3 In this embodiment of the utility model, the lifting mechanism 200 includes, for example, a lifting bracket 201 (i.e., the aforementioned lifting frame), a first transmission member 230, and a first driving member 240.

[0038] Specifically, the lifting bracket 201 is located on one side of the support base 100 and is movably connected to the support base 100. The lifting bracket 201 can reciprocate along the height direction of the support base 100. In this embodiment, the lifting bracket 201 can be, for example, a frame structure, made of metal profiles, with high structural strength, and can stably support the scanning structure 400 and the contact diameter detection structure 500.

[0039] The first transmission component 230 is disposed on the side of the support base 100 near the lifting bracket 201, and is fixedly connected to the side of the lifting bracket 201 near the support base 100. In this embodiment, the first transmission component 230 may be, for example, a synchronous belt. One end of the synchronous belt is fixed to the side of the lifting bracket 201, and the other end passes around the synchronous pulley at the top of the support base 100 and is connected to the first drive component 240. The lifting bracket 201 is driven to rise and fall through the transmission of the synchronous belt. Of course, the first transmission component 230 may also be a chain, sprocket, or other components, which are not limited here.

[0040] The first driving component 240 is fixed on the support base 100. The driving end of the first driving component 240 is connected to the first transmission component 230, and the first driving component 240 is electrically connected to the controller. In this embodiment, the first driving component 240 can be, for example, a servo motor, which has the characteristics of stable speed and precise control. Its output shaft is connected to the synchronous pulley (or sprocket) through a coupling. It can receive signals sent by the controller and precisely control the lifting speed and stroke of the lifting bracket 201 to ensure the positioning accuracy of the first position and the second position.

[0041] In this embodiment, the lifting bracket 201, the first transmission component 230 and the first drive component 240 work together to achieve stable reciprocating motion of the lifting mechanism 200 along the height direction of the support base 100. Furthermore, with the help of the electrical connection between the first drive component 240 and the controller, the lifting stroke and position switching can be precisely controlled, providing reliable drive support for the continuous operation of contact diameter detection and scanning, and further improving the overall operational stability and control accuracy of the device.

[0042] See Figure 3 In this embodiment of the invention, the integrated device 10 for scanning and detecting the diameter of the roll material further includes, for example, a first slider (not shown) and a first guide rail 330. The first slider is fixed to the side of the lifting mechanism 200 near the support base 100. In this embodiment, the first slider may be, for example, a rectangular block structure made of metal material, with a groove on its inner side that matches the guide rail. Lubricating grease can be embedded in the groove to reduce frictional resistance during sliding. The first slider is fixed to the side of the lifting bracket 201 by bolts to ensure synchronous movement with the lifting mechanism 200. The first guide rail 330 is fixed to the side of the support base 100 near the lifting mechanism 200. The first guide rail 330 is located near the first transmission member 230 and extends along the height direction of the support base 100. The first guide rail 330 and the first slider slide in cooperation. In this embodiment, the first guide rail 330 may be, for example, a linear guide rail whose length matches the height of the support base 100. It is fixed to the side of the support base 100 corresponding to the lifting bracket 201 by screws and is arranged parallel to the first transmission member 230. In this embodiment, the sliding cooperation between the first slider and the first guide rail 330 provides precise guidance for the reciprocating motion of the lifting mechanism 200, effectively avoiding deviation or shaking caused by uneven force on the transmission components during the lifting process, and providing structural protection for contact detection and scanning operations.

[0043] See also Figure 1In this embodiment of the invention, the integrated device 10 for scanning and detecting the diameter of rolled material further includes, for example, a second slider (not shown), a second guide rail (not shown), and a second drive member 450. The second slider is, for example, fixed to the side of each of the first and second longitudinal beams 430 and 440 near the crossbeam 401. The structure of the second slider is similar to that of the first slider, and will not be described in detail here. Specifically, the second guide rail is, for example, located on the side of the crossbeam 401 near the first and second longitudinal beams 430 and 440, extending along the length of the crossbeam 401, and slidingly engaging with the second slider; the second guide rail can be, for example, a linear guide rail to ensure guiding accuracy. The second transmission member 460 is located on the side of the crossbeam 401 near the first and second longitudinal beams 430 and 440, and is fixedly connected to the second slider. It can be, for example, a synchronous pulley or a ball screw, and will not be described in detail here. The second drive component 450 is fixed to the end of the crossbeam 401. The drive end is connected to the second transmission component 460 via a coupling or gear set. The second drive component 450 can be, for example, a servo motor. The second drive component 450 is electrically connected to the controller and can receive signals from the controller to accurately control the rotation angle. Then, the second transmission component 460 drives the first longitudinal beam 430 and the second longitudinal beam 440 to move accurately along the second guide rail, ensuring that the first scanning component 410 and the second scanning component 420 are adapted to the scanning positions at both ends of the roll material.

[0044] In this embodiment, by setting the sliding engagement between the second slider and the second guide rail, precise guidance is provided for the movement of the first longitudinal beam 430 and the second longitudinal beam 440. Combined with the linkage between the second transmission component 460 and the second driving component 450, the first longitudinal beam 430 and the second longitudinal beam 440 are able to move smoothly and controllably along the crossbeam 401, ensuring that the first scanning component 410 and the second scanning component 420 can quickly adapt to the positions of the two ends of rolls of different lengths, thereby improving the flexibility and accuracy of the scanning operation.

[0045] See also Figure 1In this embodiment of the invention, the lifting mechanism 200 has, for example, a first end 210 and a second end 220 in a first direction, wherein the first direction is the height direction of the support base 100, and the first end 210 is higher than the second end 220; the contact diameter detection structure 500 includes, for example, a connector 510, a movable rod 520, a contact 530 (i.e., the aforementioned contact detection end), and a sensor 540 (i.e., the aforementioned sensing unit). One end of the connector 510 is fixedly connected to the lifting mechanism 200, and the connector 510 is disposed close to the first end 210. The connector 510 has an extension end 511 extending along a second direction. The extension end 511 of the connector 510 of the contact diameter detection structure 500 extends along the second direction, so that the contact 530 can face the outer circle of the coil. In some embodiments, the second direction is, for example, perpendicular to the first direction, and the second direction is, for example, a direction perpendicular to a third direction on a horizontal plane. In this way, a precise spatial reference is provided for the motion control of each component of the device, further improving the reliability and adjustability of the overall operation.

[0046] In this embodiment, the connector 510 can be, for example, a straight metal rod, fixed to the side of the lifting bracket 201 by bolts. Its extension end 511 extends horizontally away from the support base 100, providing mounting support for the movable rod 520. The movable rod 520 passes through the extension end 511 of the connector 510, extends along the first direction (i.e., the height direction of the support base 100), and can move up and down relative to the connector 510. The movable rod 520 can be, for example, a cylindrical guide shaft made of high-hardness alloy steel, precisely matched with the guide hole on the extension end 511, ensuring smooth sliding without radial wobble during lifting, and its length is adapted to the stroke requirements of contact detection.

[0047] Specifically, the contact element 530 is fixed to the bottom end of the movable rod 520, and may be a disc-shaped structure. The contact element 530 can move synchronously with the movable rod 520. The sensing element 540 is disposed on the connecting member 510 and is located close to the movable rod 520. The sensing end is located corresponding to the movable rod 520. The sensing element 540 is electrically connected to the controller and is used to sense the displacement of the movable rod 520 to perform diameter detection. In this embodiment, the sensing element 540 may be, for example, a photoelectric sensor or a displacement sensor. When the lifting mechanism 200 drives the contact-type diameter detection structure 500 to descend, after the contact element 530 contacts the coil, the movable rod 520 moves upward relative to the connecting member 510. The sensing element 540 captures the displacement signal and transmits it to the controller. The controller immediately records the actual descent height of the lifting mechanism 200, combines the difference between the initial height and the actual descent height, and then calls the compensation parameter library built into the controller for different coil diameters. The compensation parameters corresponding to different coil diameter ranges are corrected, and finally the actual diameter of the coil is accurately calculated, which greatly improves the detection accuracy.

[0048] In this embodiment, the connection of the connector 510, the movable rod 520, the contact element 530 and the sensing element 540 are combined to achieve accurate triggering and data acquisition of contact diameter detection. The up and down movement of the movable rod 520, combined with the displacement monitoring of the sensing element 540, ensures that the outer circle of the coil can provide an instant feedback signal when it comes into contact, providing a reliable basis for diameter calculation and further improving the sensitivity and accuracy of contact detection.

[0049] See Figure 4 In this embodiment of the utility model, a connecting through hole 512 is provided on the extension end 511 of the connector 510, and the movable rod 520 is slidably connected in the connecting through hole 512, for example.

[0050] Specifically, the connecting through hole 512 extends through the extension end 511 along the first direction, and its diameter is slightly larger than the diameter of the movable rod 520. In this embodiment, the connecting through hole 512 can be, for example, a precision-machined round hole, forming a clearance fit with the movable rod 520 to ensure that the movable rod 520 can slide smoothly up and down along the through hole. At the same time, the radial limit of the movable rod 520 by the hole wall prevents it from shifting or tilting during movement. This embodiment provides a stable mounting and guiding foundation for the movable rod 520, making the up and down movement of the movable rod 520 more precise and controllable, ensuring that the contact element 530 can act perpendicularly on the outer circle of the coil, and in conjunction with the sensing element 540 to monitor displacement, further improving the stability and data reliability of the contact diameter detection.

[0051] See also Figure 4 In this embodiment of the invention, the contact member 530 is, for example, a disc structure. The bottom of the contact member 530 has a contact surface for contacting the outer circle of the coil to perform diameter detection. The contact member 530 can be, for example, a circular metal disc or a wear-resistant plastic disc, and is not specifically limited here. The contact member 530 is fixed to the bottom end of the movable rod 520 by bolts or welding, and is coaxially arranged with the movable rod 520. The contact surface at the bottom of the contact member 530 can be, for example, smoothed and polished, or covered with a rubber anti-slip pad to avoid scratching the outer circle of the coil and to increase the contact friction with the coil, ensuring that it is not easy to slip during contact.

[0052] When the lifting mechanism 200 drives the contact diameter detection structure 500 to descend, the contact surface of the contact element 530 first contacts the outer circle of the coil. The disc structure can provide a larger contact area, making the contact signal more stable, further improving the accuracy of the sensor 540 in displacement monitoring, and ensuring the reliability of the diameter detection data.

[0053] See also Figure 4In this embodiment of the utility model, the integrated device 10 for scanning and detecting the diameter of the roll material also includes, for example, a first limiting structure 600. The first limiting structure 600 is fixed to the connector 510, located near the movable rod 520 and on the side of the connector 510 near the contact member 530.

[0054] Specifically, the first limiting structure 600 can be, for example, a limit switch, a limit block, or an elastic retaining ring; no specific limitation is made here. The first limiting structure 600 is used to limit the movement distance of the contact member 530 relative to the movable rod 520. When the movable rod 520 moves downward with the contact member 530 to its maximum stroke, the first limiting structure 600 can form a block between the bottom of the movable rod 520 and the top of the contact member 530, preventing the movable rod 520 from moving excessively upward and improving the safety and stability of the structure's operation.

[0055] See Figure 5 , Figure 6 and Figure 7 In this embodiment of the invention, the integrated device 10 for scanning and detecting the diameter of the roll material further includes, for example, a second limiting structure 700. The second limiting structure 700 is disposed on the crossbeam 401 and is used to limit the movement limit positions of the first scanning element 410 and the second scanning element 420. The second limiting structure 700 may be, for example, a travel limit switch, including two limiting elements, which are respectively fixed on the crossbeam 401 and close to the center of the crossbeam 401, and are electrically connected to the controller.

[0056] When the first scanning element 410 and the second scanning element 420 move to their maximum stroke along both ends of the crossbeam 401 towards the center, the second limiting structure 700 can trigger a signal or use a physical barrier (such as a buffer block) to prevent excessive movement of the scanning elements or to prevent rigid collisions between the scanning elements and the ends of the crossbeam. Specifically, the limit switch transmits a trigger signal to the controller, which immediately stops the second driving element 450, achieving precise limiting; the buffer block absorbs impact energy, protecting the scanning elements and the crossbeam structure, extending the equipment's lifespan, and ensuring the safety and controllability of the scanning element movement process.

[0057] In summary, in a specific embodiment of this utility model, the working principle of the integrated device 10 for coil scanning and diameter detection is as follows: After the device is started, the initial reset of each mechanism is completed first. The controller controls the first drive component 240 of the lifting mechanism 200 to start, and drives the lifting bracket 201 to rise to the initial position along the first guide rail 330 of the support base 100 through the first transmission component 230. At this time, the contact component 530 of the contact diameter detection structure 500 is at the highest position. The controller has preset parameters such as compensation parameter library for different coil diameters, initial height (e.g., the distance between the contact component 530 and the reference plane of the coil conveyor line) and initial spacing of the scanning component, which provide a reference for subsequent detection and scanning.

[0058] When the external conveying mechanism delivers the roll to be inspected to the inspection position on the side of the support 100, the controller receives the roll arrival signal and starts the inspection program. First, it controls the first drive component 240 to run, driving the lifting bracket 201 to descend smoothly along the first guide rail 330. The sliding cooperation between the first slider and the first guide rail 330 ensures no deviation during the lifting process. The contact diameter detection structure 500 fixed to the lifting bracket 201 descends synchronously. At this time, the movable rod 520 hangs naturally along the connecting through hole 512 of the extension end 511 of the connector 510 under the action of gravity, and the contact component 530 faces... Towards the outer circle of the coil; after the bottom contact surface of the contact member 530 contacts the outer circle of the coil, the lifting bracket 201 continues to descend slightly, the movable rod 520 moves upward relative to the connecting member 510, the sensing member 540 captures the displacement signal of the movable rod 520 and transmits it to the controller, the controller immediately records the actual descent height of the lifting mechanism 200, combines the difference between the initial height and the actual descent height, and then calls the compensation parameter library built into the controller for different coil diameters, corrects the compensation parameters corresponding to different coil diameter ranges, and finally accurately calculates the actual diameter of the coil.

[0059] After the diameter detection is completed, the controller controls the first drive unit 240 to continue running, driving the lifting bracket 201 to descend along the first guide rail 330 to the second position, i.e., the chip scanning position. At this time, the first scanning unit 410 and the second scanning unit 420 are exactly at the center height of the paper core tube of the roll. The contact unit 530 remains in contact with the outer circle of the roll as the lifting bracket 201 descends, and the movable rod 520 maintains its displacement state. Then, the controller controls the second drive unit 450 to start again, driving the first longitudinal beam 430 and the second longitudinal beam 440 to move in opposite directions along the second guide rail through the second transmission unit 460. The cooperation between the second slider and the second guide rail ensures smooth movement. When the scanning unit approaches both ends of the roll, the controller accurately controls the moving distance according to the preset roll length parameters. After the first scanning unit 410 and the second scanning unit 420 move to the corresponding position in the center of the paper core tube, the controller sends a scanning command. The two scanning units simultaneously read the RFID chip information at both ends of the roll. After reading, the data is transmitted to the controller for storage.

[0060] After scanning is completed, the controller controls the second drive component 450 to run in reverse, driving the first longitudinal beam 430 and the second longitudinal beam 440 to move in opposite directions along the second guide rail; simultaneously, the controller controls the first drive component 240 to run in reverse, driving the lifting bracket 201 to rise along the first guide rail 330 to the initial position, the contact component 530 separates from the outer circle of the roll, and the movable rod 520 resets under gravity; then the external conveying mechanism removes the inspected roll, the equipment returns to its initial state, and waits for the next roll to enter the inspection position, repeating the above work cycle. Throughout the process, the guiding effect of the first guide rail 330 and the first slider, and the second guide rail and the second slider ensures the smooth movement of each component; the first limit structure 600 and the second limit structure 700 prevent related components from overtravel; the cooperation between the transmission component and the drive component achieves precise control; the coordination of the movable rod 520, the contact component 530 and the sensing component 540 ensures the detection accuracy; the longitudinal beam structure improves the stability of the scanned component; and all structures achieve efficient collaborative operation under the coordination of the controller.
