Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of material detection, and particularly relates to a material detection device. BACKGROUND

[0002] In online material detection, a rejection device is often needed to reject unqualified material from the line.

[0003] In the related art, when the number of materials on the feeding conveying line is large during the rejection operation of the material, qualified materials may follow unqualified materials and be clamped between the conveying plate and the feeding conveying line by the conveying plate of the rejection device, and material clamping occurs. However, during the material detection, whether the material is clamped between the conveying plate and the feeding conveying line cannot be detected in real time, so that the operator cannot easily find the material clamping phenomenon, and thus the clamped material cannot be processed in time, so that the materials are accumulated on the rejection device and the feeding conveying line, and even the entire material detection device cannot operate normally.

[0004] Therefore, in the related art, the material clamping phenomenon cannot be detected in real time, so that the operator cannot process in time. CONTENT OF THE UTILITY MODEL

[0005] The embodiment of the application provides a material detection device, which can solve the problem that the operator cannot process in time due to the fact that the material clamping phenomenon cannot be detected in real time in the related art.

[0006] The embodiment of the application provides a material detection device, which can solve the problem that the operator cannot process in time due to the fact that the material clamping phenomenon cannot be detected in real time in the related art.

[0007] The X-ray detection device comprises a feeding conveying line;

[0008] The rejection device is arranged at the output end of the feeding conveying line, and comprises a first driving mechanism and a conveying plate connected with the first driving mechanism. The first driving mechanism is used to drive the conveying plate to switch between an initial position and a rejection position. In the case that the X-ray detection device detects that the material conveyed on the feeding conveying line is unqualified material, the first driving mechanism drives the conveying plate to switch to the rejection position, so that the unqualified material falls from the conveying plate.

[0009] The material clamping detection assembly is used to detect whether the material blocks the conveying plate from returning to the initial position.

[0010] In the embodiment of the present application, the material clamping detection assembly detects whether the material blocks the conveying plate from returning to the initial position, so that the material clamping between the conveying plate and the feeding conveying line can be detected in real time and effectively. When the material clamping detection assembly detects that the material blocks the conveying plate from returning to the initial position, that is, when the material clamping between the conveying plate and the feeding conveying line is detected, the material clamping detection assembly can send a signal so that the operator can know the material clamping phenomenon in time, and then the clamped material can be processed in time, or the material detection equipment can be stopped by the material clamping detection assembly, and the like, so as to protect the material and the material detection equipment.

[0028] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0029] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a category, and are not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0030] The material detection device provided by the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments and application scenarios.

[0031] Reference Figures 1-8The material detection device provided by the embodiment of the application can include an X-ray detection device 500 and a rejection device 400, wherein the X-ray detection device 500 includes a feeding conveying line 200, the rejection device 400 can be arranged at an output end of the feeding conveying line 200, the rejection device 400 includes a first driving mechanism 420 and a conveying plate 410 connected with the first driving mechanism 420, and the first driving mechanism 420 can be used to drive the conveying plate 410 to switch between an initial position and a rejection position; wherein in the case that the X-ray detection device 500 detects that the material 100 conveyed on the feeding conveying line 200 is unqualified material 110, the first driving mechanism 420 drives the conveying plate 410 to switch to the rejection position, so that the unqualified material 110 falls off from the conveying plate 410, thereby completing the rejection of the unqualified material 110. It should be noted that when the conveying plate 410 is located at the rejection position, a falling space can be formed between the conveying plate 410 and the feeding conveying line 300, and the material 100 can fall off from the falling space.

[0032] The material detection device can further include a material clamping detection assembly, which can be used to detect whether the material 100 blocks the conveying plate 410 from returning to the initial position, that is, the material detection assembly can be used to detect whether material clamping occurs.

[0033] In this way, by detecting whether the material 100 blocks the conveying plate 410 from returning to the initial position through the material clamping detection assembly, it can be detected in real time and effectively whether the material clamping occurs between the conveying plate 410 and the feeding conveying line 300, when the material clamping detection assembly detects that the material 100 blocks the conveying plate 410 from returning to the initial position, that is, when the material clamping detection assembly detects that the material clamping occurs between the conveying plate 410 and the feeding conveying line 300, the material clamping detection assembly can send a signal, so that the operator can know in time that the material clamping occurs, thereby processing the clamped material 100 in time, or the material clamping detection assembly controls the material detection device to stop and the like, thereby protecting the material 100 and the material detection device.

[0034] The X-ray detection device 500 refers to a device for detecting materials by using X-ray scanning technology, and can further include a ray source, a detector and related hardware components, which are not limited here and can be implemented according to the existing ray detection principle.

[0035] In an optional embodiment, the material clamping detection assembly can be communicatively connected with the first driving mechanism 420, and in the case that the material clamping detection assembly detects that the material 100 blocks the conveying plate 410 from returning to the initial position, the first driving mechanism 420 drives the conveying plate 410 to switch to the ejection position. In this way, the clamped material 100 can be dropped, thereby protecting the material 100 and avoiding equipment failure of the ejection device 400 due to long-term clamping of the material, thereby protecting the ejection device 400 and prolonging the service life of the ejection device 400.

[0036] Of course, the material clamping detection assembly can also be communicatively connected with the X-ray detection device of the material detection equipment and the second driving mechanism 440 of the ejection device 400 described below, and in the case that the material clamping detection assembly detects that the material 100 blocks the conveying plate 410 from returning to the initial position, the X-ray detection device and the second driving mechanism 440 can both stop, thereby stopping the entire material detection equipment, stopping the conveying plate 410 from conveying the material 100, and stopping the feeding conveying line 200 from conveying the material 100 to the conveying plate 410. In this way, mutual abrasion between the conveying plate 410 and the clamped material 100 can be avoided, thereby protecting the clamped material 100, and since the conveying plate 410 stops running, the conveying plate 410 can be prevented from malfunctioning, thereby reducing the failure rate of the ejection device 400, and also avoiding accumulation of the material 100 on the conveying plate 410.

[0037] In an optional embodiment of the present application, the material clamping detection assembly includes a position detection element 470 for detecting the position of the conveying plate 410. In this way, by detecting the position of the conveying plate 410, it can be determined whether the material clamping occurs between the conveying plate 410 and the feeding conveying line 300.

[0038] In the embodiment of the present application, the position of the conveying plate 410 is detected by the position detection element 470 to detect whether the material clamping occurs between the conveying plate 410 and the feeding conveying line 300, which is not easily affected by other external factors and is more accurate.

[0039] Optionally, the material clamping detection assembly can also include a time detection element, which can be used to detect the time from when the conveying plate 410 leaves the initial position to when it returns to the initial position. In the case that the time detected by the time detection element is greater than a preset time and the position detection element 470 detects that the conveying plate 410 has not returned to the initial position, it indicates that the material 100 blocks the conveying plate 410 from returning to the initial position, i.e., that the material clamping occurs between the conveying plate 410 and the feeding conveying line 300.

[0040] It should be noted that the preset time can be the time for the conveying plate 410 to leave the initial position and return to the initial position under normal circumstances, i.e. the time for the conveying plate 410 to leave the initial position and return to the initial position when there is no material clamped between the conveying plate 410 and the feeding conveying line 300. Here, the preset time can be 5 seconds, for example. Alternatively, the time detection element can be a timer or a time relay, etc.

[0041] Alternatively, the rejecting device 400 further comprises a fixed frame 430, the conveying plate 410 is rotatably connected to the side of the fixed frame 430 close to the X-ray detection device 500, and the position detection element 470 is arranged at the side of the fixed frame 430 away from the X-ray detection device 500. In this way, the position detection element 470 can more easily detect the position change of the conveying plate 410, and thus more easily detect whether the material is clamped between the conveying plate 410 and the feeding conveying line 300.

[0042] In other embodiments, the position detection element 470 can also be arranged at the middle position of the fixed frame 430 or at the position of the fixed frame 430 close to the X-ray detection device 500.

[0043] Further alternatively, the conveying plate 410 can be rotatably connected to the fixed frame 430 through the rotating shaft 460, and the arrangement height of the position detection element 470 can be the same as the arrangement height of the rotating shaft 460. In this way, the position detection element 470 can be located at the initial position of the conveying plate 410 or closer to the initial position of the conveying plate 410, and thus more easily detect whether the conveying plate 410 returns to the initial position.

[0044] In other embodiments, the arrangement height of the position detection element 470 can also be arranged to be lower or higher than the arrangement height of the rotating shaft 460.

[0045] In the optional embodiments, the material detection apparatus further comprises the feeding conveying line 300, which is located downstream of the rejecting device 400 and is used for conveying the qualified material 120, and the position detection element 470 can be arranged at the end of the feeding conveying line 300 close to the rejecting device 400. In this way, the space on the feeding conveying line 300 can be effectively utilized, which is conducive to simplifying the structure of the rejecting device 400.

[0046] In the optional embodiments, the position detection element 470 can comprise at least one of a proximity switch, a micro switch, a distance sensor and a travel switch. Of course, the position detection element 470 can also be other detection elements capable of detecting the position of the conveying plate 410.

[0047] In another alternative embodiment of the present application, the conveying plate 410 comprises a conveying belt 412 for conveying the material 100, and the rejecting device 400 further comprises a second driving mechanism 440 connected with the conveying belt 412 and configured to drive the conveying belt 412 to move, so as to facilitate the conveying of the qualified material 120 to the feeding conveying line 300 or the dropping of the unqualified material 110.

[0048] In addition, the material jam detection assembly can comprise a state detection element arranged on the rejecting device 400 and configured to detect the working state of the second driving mechanism 440. When the material 100 blocks the conveying plate 410 from returning to the initial position, i.e., the material jam between the conveying plate 410 and the feeding conveying line 300, the material 100 will hinder the movement of the conveying belt 412, so that the conveying belt 412 cannot move, and thus the working state of the second driving mechanism 440 changes. Therefore, by detecting the working state of the second driving mechanism 440 through the state detection element, the material jam between the conveying plate 410 and the feeding conveying line 300 can be indirectly detected.

[0049] In the embodiment of the present application, the method of detecting whether the material jam occurs by detecting the working state of the second driving mechanism 440 through the state detection element has low cost, small space occupation, and does not need to be arranged close to the output end of the conveying plate 410 or close to the input end of the feeding conveying line 300.

[0050] In other embodiments, the material jam detection assembly can comprise a camera which can be arranged on the rejecting device 400 or arranged on the end of the feeding conveying line 300 close to the rejecting device 400, so as to detect whether the material 100 blocks the conveying plate 410 from returning to the initial position. Specifically, the camera can capture the image between the conveying plate 410 and the feeding conveying line 300, and then determine whether the material jam occurs between the conveying plate 410 and the feeding conveying line 300.

[0051] Optionally, the state detection element can be in communication connection with the second driving mechanism 440. When the state detection element detects that the working state of the second driving mechanism 440 changes, the second driving mechanism 440 can be stopped, so as to stop the movement of the conveying belt 412. In this way, on the one hand, the mutual abrasion between the conveying belt 412 and the jammed material 100 can be avoided, and on the other hand, the failure of the second driving mechanism 440 can be avoided.

[0052] Further optionally, the state detection element can also be in communication connection with the first driving mechanism 420, in the case that the state detection element detects that the working state of the second driving mechanism 440 changes, the first driving mechanism 420 can drive the conveying plate 410 to switch to the ejection position, so that the clamped material 100 falls off.

[0053] In an optional embodiment, the state detection element can include a current detection element, which is used to detect the current information of the second driving mechanism 440. When the material 100 blocks the conveying plate 410 from returning to the initial position, that is, the material 100 clamps between the conveying plate 410 and the feeding conveying line 300, the material 100 will hinder the movement of the conveying belt 412, causing the conveying belt 412 to be unable to move, and thus causing the current of the second driving mechanism 440 to increase. Therefore, by detecting the current information of the second driving mechanism 440 through the current detection element, it can be indirectly detected whether the material 100 clamps between the conveying plate 410 and the feeding conveying line 300. It should be noted that the current detection element can be used to directly detect the current change of the second driving mechanism 440, or the current detection element can be used to detect the current value of the second driving mechanism 440, and then compare the current value of the second driving mechanism 440 with the initial current value of the second driving mechanism 440 (such as the current value when no clamping occurs) to determine whether the material 100 clamps between the conveying plate 410 and the feeding conveying line 300.

[0054] Optionally, the current detection element can be a current sensor, which can detect the current value of the second driving mechanism 440, or when the second driving mechanism 440 is a three-phase asynchronous motor, the current detection element can be a motor controller, which can obtain the current change of the second driving mechanism 440; when the second driving mechanism 440 is a servo motor, the current detection element can also be a servo driver, which can detect the current value of the second driving mechanism 440.

[0055] Here, the current detection element can be in communication connection with the second driving mechanism 440, in the case that the current detection element detects that the current value of the second driving mechanism 440 is greater than a preset current (specifically according to the ejection requirement), the second driving mechanism 440 stops. And the current detection element can also be in communication connection with the first driving mechanism 420, in the case that the current detection element detects that the current value of the second driving mechanism 440 is greater than the preset current, the first driving mechanism 420 drives the conveying plate 410 to switch to the ejection position, so that the clamped material 100 falls off.

[0056] It should be noted that the preset current can be the current of the second driving mechanism 440 when it is working normally, that is, the preset current can be the working current of the second driving mechanism 440 when there is no material clamped between the conveying plate 410 and the conveying line.

[0057] In another alternative embodiment, the state detecting element can include a torque detecting element for detecting torque information of the second driving mechanism 440. When the material 100 blocks the conveying plate 410 from returning to the initial position, i.e. the material 100 is clamped between the conveying plate 410 and the feeding conveying line 300, the material 100 will hinder the movement of the conveying belt 412, causing the conveying belt 412 to be unable to move, and thus causing the output torque of the second driving mechanism 440 to increase. Therefore, by detecting the change in the output torque of the second driving mechanism 440 through the torque detecting element, it can be indirectly detected whether the material 100 is clamped between the conveying plate 410 and the feeding conveying line 300. It should be noted that the torque detecting element can be used to directly detect the change in the torque of the second driving mechanism 440, or the torque detecting element can be used to detect the torque value of the second driving mechanism 440, and then compare the torque value of the second driving mechanism 440 with the initial torque value of the second driving mechanism 440 (which can be the torque value when no clamping occurs) to determine whether the material 100 is clamped between the conveying plate 410 and the feeding conveying line 300.

[0058] Alternatively, the torque detecting element can be a torque sensor, which can directly detect the torque value of the second driving mechanism 440, or when the second driving mechanism 440 is a three-phase asynchronous motor, the torque detecting element can be a motor controller, which can obtain the torque change of the second driving mechanism 440; when the second driving mechanism 440 is a servo motor, the torque detecting element can also be a servo driver, which can detect the torque value of the second driving mechanism 440.

[0059] Here, the torque detecting element can be in communication connection with the second driving mechanism 440, and when the torque detecting element detects that the torque value of the second driving mechanism 440 is greater than a preset torque (which is determined according to the ejection requirement), the second driving mechanism 440 stops. In addition, the torque detecting element can also be in communication connection with the first driving mechanism 420, and when the torque detecting element detects that the torque value of the second driving mechanism 440 is greater than the preset torque, the first driving mechanism 420 drives the conveying plate 410 to switch to the ejection position, so that the clamped material 100 falls off.

[0060] It should be noted that the preset torque can be the output torque of the second driving mechanism 440 when it is working normally, i.e. the preset torque can be the output torque of the second driving mechanism 440 when there is no material clamped between the conveying plate 410 and the conveying line.

[0061] In yet another alternative embodiment, the state detection element can include a current detection element and a torque detection element, so that the state change of the second driving mechanism 440 can be detected in two aspects of detecting the current information of the second driving mechanism 440 by the current detection element and detecting the torque information of the second driving mechanism 440 by the torque detection element, and thus the detection accuracy of the state detection element can be improved.

[0062] In other embodiments, the state detection element can also include at least one of a rotation speed detection element, a vibration detection element and a power detection element, or can also include other detection elements capable of detecting the state of the second driving mechanism 440.

[0063] In the alternative embodiment, the material detection device further includes an alarm device, which can be in communication connection with the material blocking detection assembly, and the alarm device is used to alarm when the material blocking detection assembly detects that the material 100 blocks the recovery of the conveying plate 410 to the initial position. In this way, the operator can be informed in time that the material blocking occurs between the conveying plate 410 and the feeding conveying line 300, and thus the blocked material 100 can be taken out in time, so as to further protect the material 100 and avoid the failure of the rejection device 400 due to long-time material blocking. For example, the alarm device can include a sound alarm, a light alarm or an alarm with both sound and light alarm functions.

[0064] Alternatively, the material detection device can further include a controller, which is in communication connection with the material blocking detection assembly, the first driving mechanism 420 and the alarm device, and the material blocking detection assembly can transmit the detection signal to the controller, and the controller controls the first driving mechanism 420 and / or the alarm device according to the detection signal. For example, when the material blocking detection assembly detects that the material 100 blocks the recovery of the conveying plate 410 to the initial position, the controller controls the first driving mechanism 420 to drive the conveying plate 410 to rotate to the rejection position, so that the blocked material 100 falls off, and / or the controller controls the alarm device to alarm, so that the operator can be informed in time that the material blocking occurs, and thus the blocked material 100 can be handled in time.

[0065] The controller can also be in communication connection with the second driving mechanism 440, and when the material blocking detection assembly detects that the material 100 blocks the recovery of the conveying plate 410 to the initial position, the controller controls the second driving mechanism 440 to stop, so that the conveying plate 410 stops moving.

[0066] In the embodiment, the controller can also be communicatively connected with the X-ray detection device 500, and the X-ray detection device 500 can transmit a detection signal to the controller, and the controller can control the first driving mechanism 420 to drive the conveying plate 410 to switch between the initial position and the rejection position according to the detection signal of the X-ray detection device 500, and when the material blocking detection assembly detects that the material 100 blocks the conveying plate 410 to return to the initial position, the controller can also control the feeding conveying line 200 to stop conveying the material 100, so as to avoid the material 100 from accumulating on the conveying plate 410.

[0067] Optionally, the material detection device can further include a data recording module, the data recording module can be communicatively connected with the controller, and the data recording module can be used to record the material blocking condition between the conveying plate 410 and the feeding conveying line 300. In this way, it is convenient for the operator to view the specific material blocking data, and then it is convenient to adjust the spacing between the materials 100 and the conveying speed of the feeding conveying line 200 and the conveying plate 410. Further optionally, the material detection device can further include a display, the display can be communicatively connected with the controller and the data recording module, and the display can be used to display the data recorded by the data recording module, so as to facilitate the operator to view.

[0068] Here, the data recording module can be used to record the time point at which the material blocking occurs between the conveying plate 410 and the feeding conveying line 300, and the number of times of material blocking. It should be noted that the data recording module can include a time module and a counter, the counter can be used to calculate the number of times of material blocking, when the material blocking occurs, the data recording module records the time point at this time through the time module, and then the time point at which the material blocking occurs can be recorded, when the material blocking occurs, the counter is incremented by one, and the data recording module records the number of times of material blocking through the counter. The controller can be communicatively connected with the time module and the counter, so as to obtain the time point of material blocking and the number of times of material blocking, and transmit them to the display for display.

[0069] In the optional embodiment, the conveying plate 410 can further include a frame 411, the conveying belt 412 can be arranged on the frame 411, and the first driving mechanism 420 can be connected with the frame 411, so that the movement of the conveying belt 412 can be avoided.

[0070] Of course, the conveying plate 410 can also not include the frame 411, and the first driving mechanism 420 can be connected with the driven roller 4512 described below.

[0071] Optionally, a connecting frame 413 is provided on the frame 411. The connecting frame 413 is connected to the first drive mechanism 420, so that under the drive of the first drive mechanism 420, the connecting frame 413 drives the conveyor plate 410 to switch between the initial position and the rejection position. For example, the connecting frame 413 can be a U-shaped structure, with its two side walls connected to the middle positions of the two sides of the frame 411, and the conveyor belt 412 can pass through the U-shaped groove of the connecting frame 413. The first drive mechanism 420 can be connected to the middle position of the connecting frame 413 (not shown in the figure).

[0072] like Figure 7 As shown, the first drive mechanism 420 can be a telescopic structure. One end of the first drive mechanism 420 can be rotatably connected to the fixed frame 430, and the other end can be rotatably connected to the conveyor plate 410. The telescopic movement of the first drive mechanism 420 can drive the conveyor plate 410 to rotate, allowing the conveyor plate 410 to switch between an initial position and a rejection position. Specifically, when the clamping detection component detects that material 100 is blocking the conveyor plate 410 from returning to its initial position, the first drive mechanism 420 can retract to drive the conveyor plate 410 to rotate to the rejection position, causing the material 100 clamped between the conveyor plate 410 and the feeding conveyor line 300 to fall off. When the clamping detection component detects that no material 100 is blocking the conveyor plate 410 from returning to its initial position, the first drive mechanism 420 can extend to drive the conveyor plate 410 to rotate to its initial position. Here, the first drive mechanism 420 can be a cylinder, a hydraulic cylinder, an electric cylinder, or other telescopic structures. Of course, the first drive mechanism 420 can also be a motor. The output shaft of the motor can be connected to the rotating shaft 460, and the conveyor plate 410 is fixedly connected to the rotating shaft 460. The motor can drive the rotating shaft 460 to rotate, thereby driving the conveyor plate 410 to rotate.

[0073] Optionally, the mounting bracket 430 may include two vertical supports 431 and a horizontal support 432. The horizontal support 432 may be located between the two vertical supports 431, and both sides of the horizontal support 432 are respectively connected to the two vertical supports 431. The rotating shaft 460 may be connected to the side of the vertical support 431 near the X-ray detection device 500. One end of the first driving mechanism 420 may be rotatably connected to the horizontal support 432, and the other end of the first driving mechanism 420 may be connected to the part of the conveyor plate 410 near the vertical support 431 away from the X-ray detection device 500, thus facilitating the rotation of the conveyor plate 410.

[0074] In an optional embodiment, the second drive mechanism 440 may include a drive motor, which can be connected to the conveyor belt 412 via a transmission assembly 450 and can be used to drive the conveyor belt 412 to move so that the conveyor belt 412 can transport the material 100.

[0075] As shown in Figure 7 FIG. 4, the transmission assembly 450 can include a first transmission assembly 451 and a second transmission assembly 452, and the second transmission assembly 452 can be in transmission connection with the first transmission assembly 451 and the second driving mechanism 440 respectively.

[0076] Specifically, the first transmission assembly 451 can include a driving roller 4511 and a driven roller 4512, and the driving roller 4511 and the driven roller 4512 can be located on both sides of the frame 411 in the conveying direction of the material 100, and the driving roller 4511 and the driven roller 4512 can be rotatably connected with the frame 411, and the conveying belt 412 can be sleeved outside the driving roller 4511 and the driven roller 4512, and the second transmission assembly 452 can be connected with the second driving mechanism 440 and the driving roller 4511 respectively, so that the second driving mechanism 440 can drive the driving roller 4511 to rotate through the second transmission assembly 452, and the driving roller 4511 drives the conveying belt 412 to move through the friction between them, and in turn can convey the material 100 on the conveying belt 412 to the feeding conveying line 300.

[0077] Optionally, the driving roller 4511 can be sleeved outside the rotating shaft 460, so that on the one hand, it is not necessary to additionally reserve installation space for the driving roller 4511, thereby facilitating the reduction of the space occupied by the conveying plate 410, and it is not necessary to additionally set a connecting shaft to connect the driving roller 4511 and the frame 411, and on the other hand, the integration of the driving roller 4511 and the rotating shaft 460 can avoid the complete exposure of the rotating shaft 460 outside the conveying belt 412, thereby facilitating the improvement of the aesthetic appearance of the conveying plate 410.

[0078] Of course, the driving roller 4511 can also not be sleeved outside the rotating shaft 460, and specifically, the driving roller 4511 and the rotating shaft 460 can be arranged side by side, and the driving roller 4511 can be rotatably connected with the frame 411 through a connecting shaft.

[0079] Optionally, the second transmission assembly 452 can include a driving wheel 4521, a driven wheel 4522 and a transmission belt 4523, the driving wheel 4521 can be arranged on the output shaft of the second driving mechanism 440, the driven wheel 4522 can be rotatably arranged on the rotating shaft 460, and specifically, the driven wheel 4522 is connected with the rotating shaft 460 through a bearing, and the driven wheel 4522 can be connected with the driving roller 4511, and the driving wheel 4521 and the driven wheel 4522 can be in transmission connection through the transmission belt 4523, so that the second driving mechanism 440 can drive the driving wheel 4521 to rotate and in turn drive the driven wheel 4522 to rotate, thereby driving the driving roller 4511 to rotate, so as to realize the movement of the conveying belt 412.

[0080] In some alternative embodiments, the material detection device may also include two clamping detection components, wherein one clamping detection component may include a position detection element 470, and the other clamping detection component may include a status detection element. Thus, using two clamping detection components to detect whether material 100 is blocking the conveyor plate 410 from returning to its initial position can improve detection accuracy and precision. Furthermore, when one clamping detection component is affected by external factors, the other clamping detection component can still detect the problem.

[0081] Optionally, the two ends of the rotating shaft 460 can be connected to the sides of the two vertical supports 431 of the fixing frame 430 near the X-ray detection device 500, as in this embodiment. Figure 7 and Figure 8 As shown, the vertical support 431 may include a first support rod 4311 and a second support rod 4312. The first support rod 4311 is positioned close to the X-ray detection device 500, and the second support rod 4312 is positioned away from the X-ray detection device 500. The two ends of the rotating shaft 460 can be connected to the top ends of the first support rods 4311 of the two vertical supports 431 respectively. Furthermore, the top end of the second support rod 4312 may be lower than the top end of the first support rod 4311 to provide installation space for the position detection element 470. Here, the position detection element 470 can be mounted on the top end of the second support rod 4312 via a fixing plate 471.

[0082] In an optional embodiment of this application, the X-ray detection device 500 may further include a material detection component and a support frame for supporting the material detection component. The support frame may be disposed on the side of the feed conveyor line 200, and the material detection component may be disposed above the feed conveyor line 200 for detecting the material 100 on the feed conveyor line 200. In this embodiment, the material detection component may include an X-ray detection element.

[0083] Optionally, the material detection equipment may also include a collection box 600, which may be located below the falling space formed between the conveyor plate 410 and the feeding conveyor line 300, so as to collect the falling material 100.

[0084] When the material detection assembly of the X-ray detection device 500 detects that the material 100 on the feeding conveying line 200 is unqualified material 110, the material detection assembly sends a signal to the controller, and the controller calculates a set time for the unqualified material 110 to move to the conveying plate 410 according to the conveying speed of the feeding conveying line 200 and the distance between the material detection assembly and the conveying plate 410, and then controls the first driving mechanism 420 to drive the conveying plate 410 to rotate to the rejection position after the set time, so that the unqualified material 110 on the conveying plate 410 falls into the collecting box 600 through the falling space, and then the conveying plate 410 returns to the initial position.

[0085] When the material detection assembly detects that the material 100 blocks the conveying plate 410 from returning to the initial position, i.e., the material 100 is clamped between the conveying plate 410 and the feeding conveying line 300, the material detection assembly sends a clamping signal to the controller, and the controller controls the first driving mechanism 420 to drive the conveying plate 410 to rotate to the rejection position, so that the clamped qualified material 120 falls into the collecting box 600 through the falling space, thereby preventing the clamping of the material 100 and avoiding the damage of the qualified material 120 caused by the conveying plate 410 and the feeding conveying line 300. Of course, when the material detection assembly detects that the material 100 blocks the conveying plate 410 from returning to the initial position, the controller can also control the conveying plate 410 to stop conveying the material 100, i.e., control the conveying plate 410 to stop running, thereby avoiding the abrasion of the material 100 caused by the conveying plate 410, and at the same time, the controller can control the alarm device to alarm, so that the operator can know the clamping of the material 100 in time, thereby the clamped material 100 can be quickly removed, and the damage of the material 100 and the failure of the rejection device 400 caused by long-time clamping can be further avoided.

[0086] In order to avoid the qualified material 120 being treated as unqualified material 110, the material 100 in the collecting box 600 can be placed on the feeding conveying line 200 again, so that the material detection assembly of the X-ray detection device 500 detects the material 100 again. In this way, on the one hand, the qualified material 120 can be screened from the unqualified material 110, and on the other hand, the detection accuracy of the material 100 can be improved.

[0087] The embodiments of the present application are described above in combination with the drawings, but the present application is not limited to the specific embodiments described above, and the specific embodiments described above are only illustrative but not limiting, and those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the scope protected by the claims.
