[0037] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0038] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0039] At present, when the belt conveyor runs for a long time and the conveyor belt deviates, some correcting devices installed on the belt conveyor are usually used to correct the conveyor belt. However, some correcting devices are directly installed on the belt conveyor for use when their correcting effect is uncertain, resulting in poor correction effect of the correcting device on the conveyor belt deviation. In addition, since the belt conveyor may deviate only after running for a certain period of time during use, it is necessary to determine whether the correcting effect of the correcting device meets the actual needs, which has a certain impact on the actual production efficiency. Secondly, in the process of replacing the correcting device in the belt conveyor, it is necessary to move and disassemble the conveyor belt, which makes the operation process more complicated.

[0040] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a front view of a belt conveyor test bench provided in an embodiment of the present application, Figure 2 yes Figure 1 A top view of the belt conveyor test bench is shown. Figure 3 The belt conveyor test bench may include: a frame 100, a redirecting roller 200, a driving roller 300, a conveyor belt 400, a deviation adjustment device 500 and a deviation correction device 600.

[0041] The frame 100 in the belt conveyor may extend along a first direction f1.

[0042] The redirecting roller 200 and the driving roller 300 in the belt conveyor can be distributed at both ends of the frame 100 along the first direction f1, and the redirecting roller 200 and the driving roller 300 can be located on the same side of the frame 100, and the driving roller 300 can be fixedly connected to one end of the frame 100.

[0043] The conveyor belt 400 in the belt conveyor test bench can be wound around the redirecting roller 200 and the driving roller 300, and the bearing portion 401 in the conveyor belt 400 can be located on the side of the redirecting roller 200 and the driving roller 300 away from the frame 100. Here, the bearing portion 401 in the conveyor belt 400 can be used to carry materials, and the conveyor belt 400 can be driven to rotate around the redirecting roller 200 and the driving roller 300 during the rotation of the driving roller 300.

[0044] The deviation adjustment device 500 in the belt conveyor test bench can be connected to the frame 100 and the end of the redirecting roller 200, respectively, and the deviation adjustment device 500 can be configured to: drive the end of the redirecting roller 200 to move in a direction close to the driving roller 300 or in a direction away from the driving roller 300, so as to drive the conveyor belt 400 to deviate. Here, after the deviation adjustment device 500 drives the end of the redirecting roller 200 to move in a direction close to the driving roller 300 or in a direction away from the driving roller 300, the end of the redirecting roller 200 in a rotating state is offset, and the redirecting roller 200 as a whole presents a certain angle with the conveyor belt 400, so as to induce the conveyor belt 400 to deviate. It should be noted that when the deviation adjustment device 500 drives one end of the redirecting roller 200 to move, the other end of the redirecting roller 200 can rotate relative to the frame 100 but does not deviate.

[0045] The deviation correction device 600 in the belt conveyor test bench may be located between the redirection roller 200 and the driving roller 300. The deviation correction device 600 may include: a deviation correction component 601 and a driving lifting assembly 602. The driving lifting assembly 602 may be detachably connected to the frame 100 and the deviation correction component 601, respectively. The driving lifting assembly 602 may be configured to: drive the deviation correction component 601 to move in a direction close to the bearing portion 401 in the conveyor belt 400, so that the deviation correction component 601 may abut against the back of the bearing portion 401 in the conveyor belt 400 to correct the deviation of the conveyor belt 400. Alternatively, the deviation correction component 601 may be driven to move in a direction away from the bearing portion 401 in the conveyor belt 400, so that the deviation correction component 601 is separated from the back of the bearing portion 401 in the conveyor belt 400. Here, the driving lifting assembly 602 can drive the correcting component 601 to move in the direction close to the bearing part of the conveyor belt 400, that is, the correcting component 601 can be lifted to correct the deviated conveyor belt 400. The distance that the driving lifting assembly 602 drives the correcting component 601 to move in the direction close to the bearing part 401 of the conveyor belt 400 needs to be determined according to the degree of deviation of the conveyor belt 400 and the shape of the correcting component 601.

[0046] For example, the deviation-correcting component 601 may be a grooved roller. Figure 1 Two working states of the deviation adjustment device 600 are shown in FIG.

[0047] In the embodiment of the present application, by integrating the deviation adjustment device 500 and the correction device 600 in the belt conveyor test bench, the deviation adjustment device 500 is connected to the end of the redirection roller 200, and the end of the redirection roller 200 can be driven to deviate by the deviation adjustment device 500, thereby inducing the conveyor belt 400 to deviate. In this way, the operator can independently adjust the deviation degree of the conveyor belt 400 on the test bench in combination with the deviation phenomenon of the conveyor belt in actual production for subsequent tests. In addition, after the conveyor belt 400 deviates, the operator can operate the correction device 600, and drive the correction component 601 to move toward the direction of the load-bearing part 401 in the conveyor belt 400 through the driving lifting component 602 in the correction device 600, so as to correct the conveyor belt 400, and at the same time, the correction effect of the correction device 600 can be detected, so as to provide effective guidance for subsequent applications in actual production. Furthermore, the deviation correction component 601 can be driven to separate from the bearing part 401 in the conveyor belt 400 by driving the lifting assembly 602. In this way, the operator can replace different deviation correction components 601 installed on the driving lifting assembly 602 to test the deviation correction effect for the same degree of deviation of the conveyor belt 400 without disassembling the conveyor belt 400, and replace different deviation correction components 601 installed on the driving lifting assembly 602 to test the deviation correction effect for different degrees of deviation of the conveyor belt 400. It can be seen from the above that the conveyor belt 400 can be adjusted and corrected at the same time through the belt conveyor test bench, so that a deviation correction device with good correction effect in actual production process can be obtained with lower cost and higher efficiency.

[0048] In summary, the embodiment of the present application provides a belt conveyor test bench, which may include: a frame, a redirecting roller, a driving roller, a conveyor belt, an adjustment device and a correction device. By integrating the adjustment device and the correction device in the belt conveyor test bench, the adjustment device is connected to the end of the redirecting roller, and the end of the redirecting roller can be driven to deviate by the adjustment device, thereby inducing the conveyor belt to deviate. In this way, the operator can independently adjust the degree of deviation of the conveyor belt on the test bench in combination with the deviation phenomenon of the conveyor belt in actual production for subsequent tests. In addition, after the conveyor belt deviates, the operator can operate the correction device, and drive the correction component to move toward the direction close to the load-bearing part in the conveyor belt through the driving lifting assembly in the correction device to correct the conveyor belt, and at the same time, the correction effect of the correction device can be detected to provide guidance for subsequent applications in actual production. The deviation correction component can be separated from the load-bearing part of the conveyor belt by driving the lifting assembly. In this way, the operator can replace different deviation correction components and install them on the driving lifting assembly to test the deviation correction effect for the same degree of deviation of the conveyor belt without disassembling the conveyor belt, and replace different deviation correction components and install them on the driving lifting assembly to test the deviation correction effect for different degrees of deviation of the conveyor belt. It can be seen from the above that the conveyor belt adjustment and deviation correction tests can be carried out simultaneously through the belt conveyor test bench, so that a deviation correction device with better deviation correction effect can be obtained in the actual production process at a lower cost and higher efficiency.

[0049] For example, Figure 1 As shown, when there are multiple deflection correcting devices 600, the multiple deflection correcting devices 600 can be arranged in sequence along the first direction f1. In this way, multiple identical deflection correcting devices 600 and / or multiple different deflection correcting devices 600 can be used to perform a deflection correcting test of the conveyor belt 400 on the belt conveyor test bench. Multiple deflection correcting devices 600 can be distributed at equal intervals or at non-equal intervals. The distance between two adjacent deflection correcting devices 600 and the distance between the outermost deflection correcting device 600 and the redirecting roller 200 and the driving roller 300 can be set according to actual needs, and the embodiments of the present application do not make specific limitations on this.

[0050] Optional, please refer to Figure 4 and Figure 5 , Figure 4 is a top view of another belt conveyor test bench provided in an embodiment of the present application, Figure 5It is a partial structural schematic diagram of another belt conveyor test bench provided by an embodiment of the present application. The redirecting roller 200 in the belt conveyor test bench may have two ends arranged opposite to each other along the second direction f2; the deviation adjustment device 500 may include: two sub-deflection adjustment devices 501 corresponding to the two ends of the redirecting roller 200, respectively, and each sub-deflection adjustment device 501 may be connected to the corresponding end of the redirecting roller 200 and the frame 100. The second direction f2 may be perpendicular to the first direction f1. Wherein, when one sub-deflection adjustment device 501 is rotationally connected to the frame 100, the other sub-deflection adjustment device 501 can move relative to the frame 100 to drive one end of the redirecting roller 200 to move in a direction close to the driving roller 300 or in a direction away from the driving roller 300, thereby driving the conveyor belt 400 to deflect. For example, by setting two sub-adjustment devices 501 relatively arranged along the second direction f2 in the adjustment device 500, each sub-adjustment device 501 can be connected to one end of the redirection roller 200. In this way, the offset of each end of the redirection roller 200 can be achieved, thereby increasing the flexibility of the adjustment setting of the conveyor belt 400 in the belt conveyor test bench.

[0051] It should be noted that, when the end of the redirecting roller 200 is not offset, the two sub-adjusting devices 501 arranged along the second direction f2 can be symmetrically arranged with respect to the central axis of the redirecting roller 200. It should also be noted that, after the end of the redirecting roller 200 is driven to deflect by the sub-adjusting devices 501, screws and nuts (not shown in the figure) can be used to fix the two sub-adjusting devices 501 and the frame 100 to ensure the stable operation of the belt conveyor test bench.

[0052] In the examples of this application, please refer to Figure 5 and Figure 6 , Figure 6 yes Figure 4The side view of the belt conveyor test bench is shown. The sub-adjustment device 501 may include: a screw 501a, a stopper 501b and a slide 501c. The length direction of the screw 501a may be parallel to the first direction f1, the outer side of the screw 501a may have an external thread, and the stopper 501b may be sleeved on the screw 501a and may have an internal thread that matches the external thread. The stopper 501b may be fixedly connected to the frame 100, and the slide 501c may be connected to the end of the redirection roller 200. The screw 501a is rotated so that the end of the screw 501a abuts against the slide 501c, and then the slide 501c is pushed to move relative to the frame 100, thereby driving the end of the redirection roller 200 to move. For example, when the deviation adjustment device 500 is used to adjust the deviation of the end of the redirecting roller 200, the operator can rotate one end of the screw 501a along the first rotation direction, and the screw 501a can move along the first direction f1 through the cooperation of the external thread and the internal thread in the limiter 501b so that the other end of the screw 501a abuts against the slide 501c; then, continue to rotate one end of the screw 501a, and the screw 501a pushes the slide 501c to move a certain distance to achieve the deviation of the end of the redirecting roller 200. At the same time, after the screw 501a moves a certain stroke, due to the self-locking characteristics between the external thread in the screw 501a and the internal thread in the limiter 501b, it can be ensured that the screw 501a always generates abutment force on the slide 501c. In addition, the sub-device for deviation adjustment has a simple structure and a low manufacturing cost. Here, when it is necessary to restore the redirecting roller 200 to the initial position (the end of the redirecting roller is not offset), the operator can rotate one end of the screw rod 501a in the second rotation direction, and the screw rod 501a can move in the first direction f1 to separate from the slide 501c through the cooperation of the external thread and the internal thread in the stopper 501b. One of the first rotation direction and the second rotation direction can be counterclockwise, and the other can be clockwise.

[0053] For example, when the screw 501a is located at the side of the carriage 501c away from the driving roller 300, the end of the driving screw 501a moves along the first direction f1, which can drive the end of the redirecting roller 200 to deviate in the direction close to the driving roller 300. When the screw 501a is located at the side of the carriage 501c close to the driving roller 300, the end of the driving screw 501a moves along the first direction f1, which can drive the end of the redirecting roller 200 to deviate in the direction away from the driving roller 300.

[0054] In this application, if Figure 6As shown, the redirecting roller 200 may include: a redirecting roller body 201, and two supporting seats 202 arranged opposite to each other along the second direction f2, and the redirecting roller body 201 may be located between the two supporting seats 202. The supporting seat 202 may be located on a side of the slide 501c away from the frame 100, and may be fixedly connected to the slide 501c. For example, the supporting seat 202 may be fixedly connected to the slide 501c by the cooperation of a screw and a nut (not shown in the figure).

[0055] Optional, such as Figure 6 As shown, the frame 100 may have a slide rail 101, and the slide 501c in the sub-adjustment device 501 may have a slide groove a1, at least a portion of the slide rail 101 may be located in the slide groove a1, and the slide 501c may slide relative to the slide rail 101 through the slide groove a1. The slide rail 101 may have a first side b1 and a second side b2 arranged oppositely along a second direction f2, and the slide groove a1 may have a third side b3 and a fourth side b4 arranged oppositely along the second direction f2. The first side b1 in the slide rail 101 and the third side b3 in the slide groove a1 may be arranged oppositely, the second side b2 in the slide rail 101 and the fourth side b4 in the slide groove a1 may be arranged oppositely, and a first gap k1 may be provided between the first side b1 in the slide rail 101 and the third side b3 in the slide groove a1, and a second gap k2 may be provided between the second side b2 in the slide rail 101 and the fourth side b4 in the slide groove a1. In this case, by setting the slide rail 101 in the frame 100, a slide groove a1 cooperating with the slide rail 101 is set on the slide 501c, and there is a gap between the inner side surface of the slide groove a1 and the outer side surface of the slide rail 101. In this way, in the process of pushing the slide 501c to move on the slide rail 101, the slide 501c will not be stuck with the slide rail 101.

[0056] In the present application, the width of the first gap k1 between the first side b1 in the slide rail 101 and the third side b3 in the slide groove a1 in the second direction f2 may range from 5 mm to 10 mm; the width of the second gap k2 between the second side b2 in the slide rail 101 and the fourth side b4 in the slide groove a2 in the second direction f2 may range from 5 mm to 10 mm. For example, the width of the first gap k1 between the first side b1 in the slide rail 101 and the third side b3 in the slide groove a1 may be 5 mm, 7 mm or 10 mm. The width of the second gap k2 between the second side b2 in the slide rail 101 and the fourth side b4 in the slide groove a1 may be 5 mm, 7 mm or 10 mm. Here, the width of the first gap k1 between the first side b1 in the slide rail 101 and the third side b3 in the slide groove a1 and the width of the second gap k2 between the second side b2 in the slide rail 101 and the fourth side b4 in the slide groove a1 may be equal.

The other end of the connecting rod assembly 602b may be connected to at least two roller support seats 602c, and the connecting rod assembly 602b may be rotatably connected to the frame 100. At least two roller support seats 602c may be detachably connected to the deviation correcting component 601, and the third direction f3 may be perpendicular to both the first direction f1 and the second direction f2. The hand wheel 602a can be configured to: during the process of moving in the direction away from the load-bearing part 401 in the conveyor belt 400, drive one end of the connecting rod assembly 602b to rotate, and then drive at least two roller support seats 602c and the deviation correction component 601 to move toward the back side of the load-bearing part 401 in the conveyor belt 400 through the other end of the connecting rod assembly 602b. Alternatively, the hand wheel 602a can be configured to: during the process of moving in the direction close to the load-bearing part 401 in the conveyor belt 400, drive one end of the connecting rod assembly 602b to rotate, and then drive at least two roller support seats 602c and the deviation correction component 601 to move toward the back side of the load-bearing part 401 in the conveyor belt 400 through the other end of the connecting rod assembly 602b.

[0058] For example, in the case where the connecting rod assembly 602b can be located on the side of the hand wheel 602a away from the load-bearing portion 401 in the conveyor belt 400, the operator can drive the hand wheel 602a to move downward to push one end of the connecting rod assembly 602b to rotate, and the other end of the connecting rod assembly 602b rotates at the same time to drive the roller support seat 602c and the deviation correction component 601 to move in the direction close to the load-bearing portion 401 in the conveyor belt 400. In the case where the hand wheel 602a can be located on the side of the connecting rod assembly 602b away from the load-bearing portion 401 in the conveyor belt 400, the operator can drive the hand wheel 602a to move downward to pull one end of the connecting rod assembly 602b to rotate, and the other end of the connecting rod assembly 602b rotates at the same time to drive the roller support seat 602c and the deviation correction component 601 to move in the direction close to the load-bearing portion 401 in the conveyor belt 400. It should be noted that when the roller support seat 602c and the deviation correction component 601 need to be separated from the bearing part 401 in the conveyor belt 400, it is only necessary to drive the hand wheel 602a to move in the opposite direction. As can be seen from the above, by adopting the method of setting the hand wheel 602a and the connecting rod assembly 602b to drive in combination, the manufacturing cost of the deviation correction device 600 is also low while ensuring that the operator can operate flexibly. At the same time, the operator can flexibly change the contact force between the deviation correction component 601 and the conveyor belt 400 by controlling the moving stroke of the hand wheel 602a.

[0059] Optional, such as Figure 7 and Figure 8 As shown, the connecting rod assembly 602b in the driving lifting assembly 602 may include: at least two connecting rods A1 and a connecting shaft A2, one end of the at least two connecting rods A1 may be connected to at least two roller support seats 602c in a one-to-one correspondence, and at least two connecting rods A1 may be sleeved on the connecting shaft A2 and fastened to the connecting shaft A2, and the connecting shaft A2 may be rotatably connected to the frame 100. Among them, the end of the connecting rod A1 located at the outermost side away from the roller support seat 602c may also be connected to the hand wheel 602a. In this case, the operator drives the outermost connecting rod A1 to rotate through the hand wheel 602a, and then drives the other connecting rods to rotate synchronously through the connecting shaft A2, thereby driving the roller support seat 602c and the deviation correction component 601 to rise and fall.

[0060] In the embodiments of the present application, Figure 7As shown, the driving lifting assembly 602 in the deviation correction device 600 may also include: at least two guide positioning seats 602d, and the at least two guide positioning seats 602d may correspond to at least two roller support seats 602c one by one. The guide positioning seat 602d may be fixedly connected to the frame 100, and the guide positioning seat 602d may have a guide hole c1, and the extension direction of the guide hole c1 may be parallel to the moving direction of the roller support seat 602c. Among them, at least part of the roller support seat 602c may be located in the guide hole c1 in the corresponding guide positioning seat 602d, and can slide in the guide hole c1. In this case, by setting the guide positioning seat 602d, the roller support seat 602c can slide in the guide hole c1 of the guide positioning seat 602d, ensuring that the sliding stability of the roller support seat 602c is good.

[0061] Optionally, the outer side of the redirecting roller 200 in the belt conveyor test bench can be coated with a friction-reducing layer. In this case, the friction force between the conveyor belt 400 and the redirecting roller 200 can be effectively reduced, ensuring that the deviation correction device 600 can smoothly perform the deviation correction test on the conveyor belt. For example, the redirecting roller 200 can be a smooth roller without rubber coating.

[0062] In summary, the embodiment of the present application provides a belt conveyor test bench, which may include: a frame, a redirecting roller, a driving roller, a conveyor belt, an adjustment device and a correction device. By integrating the adjustment device and the correction device in the belt conveyor test bench, the adjustment device is connected to the end of the redirecting roller, and the end of the redirecting roller can be driven to deviate by the adjustment device, thereby inducing the conveyor belt to deviate. In this way, the operator can independently adjust the degree of deviation of the conveyor belt on the test bench in combination with the deviation phenomenon of the conveyor belt in actual production for subsequent tests. In addition, after the conveyor belt deviates, the operator can operate the correction device, and drive the correction component to move toward the direction close to the load-bearing part in the conveyor belt through the driving lifting assembly in the correction device to correct the conveyor belt, and at the same time, the correction effect of the correction device can be detected to provide guidance for subsequent applications in actual production. The deviation correction component can be separated from the load-bearing part of the conveyor belt by driving the lifting assembly. In this way, the operator can replace different deviation correction components and install them on the driving lifting assembly to test the deviation correction effect for the same degree of deviation of the conveyor belt without disassembling the conveyor belt, and replace different deviation correction components and install them on the driving lifting assembly to test the deviation correction effect for different degrees of deviation of the conveyor belt. It can be seen from the above that the conveyor belt adjustment and deviation correction tests can be carried out simultaneously through the belt conveyor test bench, so that a deviation correction device with better deviation correction effect can be obtained in the actual production process at a lower cost and higher efficiency.
