Description

Technical Field

[0001] The invention relates to the technical field of belt conveyors, in particular to deviation correction of conveyor belts. Background Art

[0002] Belt conveyors, as the main equipment for material transportation, are widely used in various fields such as mines, ports, and factories. During operation, conveyor belts are prone to deviation. That is, during operation, the longitudinal center line of the conveyor belt deviates from the theoretical center line of the belt conveyor. If the deviation of the conveyor belt is too large, friction may occur between the conveyor belt and the roller bracket, aggravating the wear of the conveyor belt.

[0003] Chinese patent publication number CN 207390226 U discloses a conveyor belt forced deviation correction device, in particular a protection device for the upper conveyor belt and the lower return belt to deviate, including an upper roller, an upper conveyor belt, and guards on both sides of the upper roller. The guards on both sides of the upper roller are grooved pulley assemblies, which include grooved pulleys, rolling bearings, pulley shafts, U-shaped brackets A and B, support arms, and adjustment screws. This can fundamentally eliminate the occurrence of conveyor belt deviation and loss of control.

[0004] However, the correction device disclosed in the above scheme can only limit the deviation of the conveyor belt by adjusting the distance between the grooved pulley and the conveyor belt by adjusting the screw rod, and cannot effectively correct the conveyor belt and return the conveyor belt to the center line, resulting in friction loss between the conveyor belt and the grooved pulley.

[0005] Therefore, how to effectively improve the reliability of the deviation correction device, detect and adjust the deviation of the conveyor belt in time, and reduce the wear of the conveyor belt has become an urgent problem to be solved in this field. Summary of the Invention

[0008] The deviation-correcting device is installed on the roller assembly through a mounting frame. The deviation-correcting device includes vertical rollers symmetrically arranged on both sides of the conveyor belt. The vertical rollers are elastically connected to the mounting frame for sliding. A guide limit groove adapted to the side of the conveyor belt is provided on the working surface of the vertical roller. The guide limit groove forms an elastic dynamic contact fit with the conveyor belt.

[0009] The detection device is arranged on the placement frame and is configured to detect the lateral pressure value of the vertical roller in real time to issue an alarm message.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0037] Example 1

[0038] See also Figure 1 and Figure 2 , which shows an example of the belt conveyor correction device provided by the present invention.

[0039] As can be seen from the figure, the belt conveyor correction device of this example cooperates with the roller assembly 300 and the conveyor belt 400 set on the roller assembly 300, and mainly includes a correction device 100 and a detection device 200.

[0040] The correction device 100 forms an elastic dynamic contact with the conveyor belt 400, which can push the deviated conveyor belt 400 back to the center line position in time to achieve timely correction. The detection device 200 can reflect the deviation condition of the conveyor belt 400 and remind the staff in time.

[0041] Combine Figures 2 to 5 Specifically, the correcting device 100 is set on the roller assembly 300 through the mounting frame 110, and the mounting frame 110 is set on both sides of the roller assembly 300. The correcting device 100 includes vertical rollers 120 symmetrically arranged on both sides of the conveyor belt 400, so that the vertical rollers 120 can correspond to the conveyor belt 400 and cooperate with the mounting frame 110 to realize timely correction of the conveyor belt 400.

[0042] Furthermore, the working surface of the vertical roller 120 is provided with a guide limit groove 130 adapted to the side 410 of the conveyor belt 400, and the extension center line of the guide limit groove 130 is consistent with the extension center line of the side 410 of the conveyor belt 400, so that when the conveyor belt 400 deviates, the side 410 of the conveyor belt 400 can move laterally synchronously and move into the guide limit groove 130, abutting and cooperating with the bottom of the guide limit groove 130 to limit the conveyor belt 400, so that the guide limit groove 130 limits the deviation of the conveyor belt 400.

[0043] At the same time, a deviation gap is provided between the guide limit groove 130 and the side 410 of the conveyor belt 400 , allowing the conveyor belt 400 to deviate within a small range within the deviation gap, thereby ensuring stable and smooth movement of the conveyor belt 400 .

[0044] Preferably, a buffer layer is provided on the groove wall of the guide limiting groove 130 , or the vertical roller 120 is entirely composed of a rubber roller to reduce the abutment friction between the conveyor belt 400 and the guide limiting groove 130 and improve the service life of the conveyor belt 400 .

[0045] In order to reduce the friction loss of the conveyor belt 400, the vertical roller 120 is configured to be slidably elastically connected to the mounting frame 110, so that the vertical roller 120 can be driven to rotate synchronously when the conveyor belt 400 is transported and moved, thereby reducing the friction loss of the conveyor belt 400 in the guide limit groove 130 and correcting the conveyor belt 400 at the same time.

[0046] Combine Figure 3 and Figure 4 Specifically, the vertical roller 120 is elastically connected to the mounting frame 110 through an elastic connecting member 140. The elastic connecting member 140 is provided at both ends of the vertical roller 120 and includes a spring telescopic rod 141 and a fixed support rod 142. The fixed support rod 142 is passed through the vertical roller 120, and both ends extend out of the vertical roller 120 and are connected to the spring telescopic rod 141, so that the vertical roller 120 can rotate around the fixed support rod 142. At the same time, a spring is sleeved on the spring telescopic rod 141, and one end is connected to the mounting frame 110, and the other end is connected to the fixed support rod 142, so that the spring telescopic rod 141 and the fixed support rod 142 cooperate to stably and securely connect the vertical roller 120 to the mounting frame 110.

[0047] In this way, when the conveyor belt 400 deviates and abuts the guide limit groove 130, as the conveyor belt 400 continues to move, it will drive the vertical roller 120 to rotate around the fixed support rod 142, thereby reducing the friction loss of the guide limit groove 130 on the conveyor belt 300.

[0048] Combine Figure 2 At the same time, when the conveyor belt 400 deviates and abuts against the guide limit groove 130, it will generate lateral pressure on the vertical roller 120, driving the vertical roller 120 to move toward the mounting frame 110, and synchronously compressing the spring telescopic rod 141, so that the spring telescopic rod 141 extends to its initial state under the action of its own elastic restoring force. The vertical roller 120 generates a force opposite to the lateral pressure and synchronously pushes the vertical roller 120 to move away from the mounting frame 110, thereby driving the conveyor belt 400 back to its initial center line position and correcting the deviation in time.

[0049] Combine Figure 3 and Figure 4In order to improve the connection stability between the vertical roller 120 and the mounting frame 110, the elastic connector 140 is also slidably connected to the mounting frame 110 through the guide connector 150, so that the elastic connector 140 and the guide connector 150 cooperate to ensure the stable movement of the vertical roller 120.

[0050] Specifically, the end of the guide connecting member 150 that cooperates with the vertical roller 120 is provided with a concave groove 151 adapted to the vertical roller 120, and the end that cooperates with the placement frame 110 is provided with a guide rod 152, and the placement frame 110 is provided with a guide slot hole 111 for gap fitting with the guide rod 152, so that the guide rod 152 is inserted into the guide slot hole 111, can move axially along the guide slot hole 111, and accommodate the vertical roller 120 in the concave groove 151, and the vertical roller 120 can rotate in the concave groove 151.

[0051] At the same time, both ends of the concave slot 151 extend toward the spring telescopic rod 141 and are passed through the spring telescopic rod 141 to stably connect the elastic connector 140 with the guide connector 150, so that the conveyor belt 400 deviates and drives the vertical roller 120 to move toward the placement frame 110, or when the spring telescopic rod 141 pushes the vertical roller 120 to move away from the placement frame 110, it will drive the guide connector 150 to move axially along the guide slot 111 synchronously to approach or move away from the placement frame 110, guide and limit the moving direction of the vertical roller 120, and prevent the vertical roller 120 from deviating during movement and correction, thereby ensuring the reliability of the correction of the conveyor belt 400 and stably driving the conveyor belt 400 back to the initial center line position.

[0052] In the deviation-correcting device 100 thus constructed, the vertical roller 120 is elastically connected to the mounting frame 110 through the elastic connector 140 and the guide connector 150. This not only ensures that the vertical roller 120 and the conveyor belt move synchronously and reduces the friction loss of the conveyor belt 400, but also enables the vertical roller 120 to form elastic dynamic contact with the conveyor belt 400, and timely corrects the conveyor belt 400 under the action of the elastic restoring force, thereby improving the reliability of the deviation-correcting device 100.

[0053] Combine Figures 1 to 5 In this example, the conveyor belt 400 includes a transport conveyor belt 420 and a return conveyor belt 430, which are respectively arranged in the upper and lower areas of the roller assembly 300. In order to ensure that the conveyor belt 400 is corrected as a whole and reduce the overall friction loss of the conveyor belt 400, the correction device 100 includes a first group of vertical rollers 121 and a second group of vertical rollers 122 that cooperate with the transport conveyor belt 420 and the return conveyor belt 430, respectively, so that the first group of vertical rollers 121 and the second group of vertical rollers 122 can respectively cooperate with the placement frame 110 to synchronously correct the transport conveyor belt 420 and the return conveyor belt 430.

[0054] As an example, the transport conveyor belt 420 is distributed in a U-shape, and the first group of vertical rollers 121 is arranged in the upper area of the roller assembly 300 through the placement frame 110, and the vertical rollers 120 arranged on both sides of the transport conveyor belt 420 in the first group of vertical rollers 121 are also distributed in a U-shape accordingly. The extension center line of the guide limit groove 130 in the first group of vertical rollers 121 is consistent with the extension center line of the side of the transport conveyor belt 420, ensuring the effective cooperation between the first group of vertical rollers 121 and the transport conveyor belt 420, thereby improving the correction effect of the transport conveyor belt 420.

[0055] Correspondingly, the return conveyor belt 430 is horizontally distributed, the second group of vertical rollers 122 is arranged in the lower area of the roller assembly 300 through the mounting frame 110, and the vertical rollers 120 arranged on both sides of the return conveyor belt 430 in the second group of vertical rollers 122 are also correspondingly horizontally distributed, and the extension center line of the guide limit groove 130 in the second group of vertical rollers 122 is consistent with the extension center line of the side of the return conveyor belt 430, ensuring the effective cooperation between the second group of vertical rollers 122 and the return conveyor belt 430, thereby improving the correction effect of the return conveyor belt 430.

[0056] This ensures that the conveyor belt 400 is corrected in a timely manner as a whole, and can effectively reduce the friction loss of the conveyor belt 400.

[0057] In order to ensure the reliability of the correction, the device further includes a detection device 200, which is arranged on the mounting frame 110 and is configured to detect the lateral pressure value of the vertical roller 120 in real time to issue an alarm message and promptly remind the staff.

[0058] Combine Figure 6 Specifically, the detection device 200 can be composed of an existing pressure sensor, including a pressure sensing unit 210 and a signal processing unit 220, so that the detection device 200 is set on the mounting frame 110 and connected to the vertical roller 120. The pressure sensing unit 210 detects the lateral pressure value generated by the conveyor belt 400 on the vertical roller 120 in real time, thereby obtaining the deviation condition of the conveyor belt 400. If the lateral pressure value is larger, the deviation amount of the conveyor belt 400 is greater.

[0059] Furthermore, the pressure sensing unit 210 transmits the lateral pressure value to the signal processing unit 220 in real time. A pressure threshold is preset in the signal processing unit 220, so that the signal processing unit 220 compares the lateral pressure value with the pressure threshold for judgment. If the lateral pressure value is greater than the pressure threshold, it means that the deviation of the conveyor belt 400 is too large, and the vertical roller 120 cannot effectively push the conveyor belt 400 back to the center line position under the elastic restoring force of the elastic connector 140. At this time, the signal processing unit 220 generates an alarm instruction.

[0060] Here, the preset pressure threshold in the signal processing unit 220 is adapted to the maximum deviation of the conveyor belt 400 and the elastic restoring force of the elastic connector 140, ensuring that when the lateral pressure value applied to the vertical roller 120 reaches the pressure threshold, the vertical roller 120 cannot effectively push the conveyor belt 400 back to the centerline position.

[0061] In conjunction with this, the device also includes an alarm device, which is configured to receive an alarm instruction to issue a corresponding alarm message.

[0062] Here, the alarm device can be composed of an audible and visual alarm set on the mounting frame 110 to emit audible and visual alarm information, which can promptly and effectively remind the staff to manually intervene in the conveyor belt 400 to ensure the correction effect of the conveyor belt 400.

[0063] The detection device 200 thus constructed can detect the lateral pressure value of the vertical roller 120 in real time, and promptly reflect the deviation condition of the conveyor belt 400, thereby improving the reliability of the device.

[0064] In this example, the detection device 200 cooperates with each of the first set of vertical rollers 121 and the second set of vertical rollers 122 to synchronously detect the lateral pressure value applied to each vertical roller, thereby effectively obtaining the deviation conditions of both sides of the transport conveyor belt 420 and the return conveyor belt 430, and can promptly reflect the overall deviation of the conveyor belt 400, thereby ensuring the operating stability of the conveyor belt 400.

[0065] Example 2

[0066] On the basis of Example 1, in order to improve the reliability of the correction device 100 on the conveyor belt 400, in this example, the correction device 100 is configured to be adjustable at multiple angles, accurately cooperate with the conveyor belt 400, and correct the conveyor belt 400 in a timely manner.

[0067] Combine Figure 7 and Figure 8 Specifically, the mounting frame 110 includes a vertical plate 112 and an adjustment plate 113. The vertical poles 111 are upright and fixed on both sides of the roller assembly 300. The adjustment plate 113 is connected to the correcting device 100 and is hinged to the top of the vertical pole 111 through the mounting frame adjustment assembly 500, so that the adjustment plate 113 can rotate relative to the vertical pole 111, thereby driving the correcting device 100 to rotate synchronously to adjust the angle of the vertical roller 120, so that the vertical roller 120 can cooperate with the conveyor belt 400 distributed at different groove angles for precise correction.

[0068] Furthermore, the mounting frame adjustment assembly 500 includes a hinge support 510 and a hydraulic telescopic rod 520. The hinge support 510 is respectively arranged on the vertical plate 112 and the adjustment plate 113. The two ends of the hydraulic telescopic rod 520 are respectively slidably connected to the hinge support 510 on the vertical plate 112 and the adjustment plate 113, so that the extension and contraction of the hydraulic telescopic rod 520 can drive the vertical plate 112 and the adjustment plate 113 to rotate relative to each other, thereby adjusting the angle between the adjustment plate 113 and the vertical plate 112.

[0069] In this way, the adjustment plate 113 can drive the vertical roller 120 to rotate synchronously to synchronously adjust the installation angle and position of the vertical roller 120, so that the extended center line of the guide limit groove 130 on the vertical roller 120 can be consistent with the extended center line of the side of the conveyor belt 400 distributed at different angles, thereby cooperating with conveyor belts with different groove angles to improve the correction effect.

[0070] Here, the specific structure of the hydraulic telescopic rod 520 is a conventional technical means in this field.

[0071] Furthermore, in addition to horizontal deviation, the conveyor belt 400 may also deviate or collapse in the vertical direction during transportation, which may cause the conveyor belt to deviate and lose control. In order to improve the deviation correction effect, the deviation correction device 100 is configured to correct the horizontal and vertical deviations of the conveyor belt 400.

[0072] Combine Figure 9 Specifically, in this example, the guide connecting member 150 also includes a guide telescopic rod 153, an elastic driving tube 154 and a concave card slot 151. The elastic driving tube 154 is arranged on the outer side of the adjustment plate 113, and the concave card slot 151 is arranged on the inner side of the adjustment plate 113 where it cooperates with the conveyor belt 400, accommodating the vertical roller 120 therein. The guide telescopic rod 153 is inserted into the guide slot 111 of the adjustment plate 113, one end extends to the outer side of the adjustment plate 113, passes through the elastic driving tube 154, and is elastically connected to the elastic driving tube 154, and the other end extends to the inner side of the adjustment plate 113, and is slidably connected to the concave card slot 151, so that the concave card slot 151 can rotate relative to the guide telescopic rod 153. At the same time, the elastic driving tube 154 can drive the guide telescopic rod 153 to extend and retract along the guide slot 111 of the adjustment plate 113.

[0073] Furthermore, a first elastic member 1541, such as a spring, is provided inside the elastic driving tube 154. One end of the first elastic member 1541 is connected to the end of the guide telescopic rod 153, and the other end is connected to the bottom end inside the elastic driving tube 154, so that the first elastic member 1541 can drive the guide telescopic rod 153 to move along the guide slot 111 of the adjustment plate 113 under the action of its own elastic force.

[0074] In this way, when the conveyor belt 400 deviates in the horizontal direction, it will generate lateral pressure on the vertical roller 120, driving the vertical roller 120 to move toward the mounting frame 110, which will drive the concave groove 151 and the guide telescopic rod 153 to move synchronously along the guide slot 111 of the adjustment plate 113 toward the outside of the adjustment plate 113, so that the guide telescopic rod 153 generates a compression force on the first elastic member 1541 inside the elastic driving tube 154, so that the first elastic member 1541 generates a force opposite to the lateral pressure on the guide telescopic rod 153 under the action of its own elastic force and restoring force, pushing the guide telescopic rod 153 and the concave groove 151 to move synchronously laterally away from the mounting frame 100, and synchronously pushing the vertical roller 120 to move away from the mounting frame 110, thereby driving the conveyor belt 400 back to the initial center line position, and correcting the deviation in time to ensure the reliability of horizontal correction.

[0075] Combine Figure 9 and Figure 10 In order to correct the vertical deviation or collapse of the conveyor belt 400, a spherical head 1531 is formed at the end of the guide telescopic rod 153 that cooperates with the concave slot 151. Correspondingly, a universal support 1511 is provided at the end of the concave slot 151 that cooperates with the guide telescopic rod 153, and a spherical groove 1512 that matches the spherical head 1531 is provided on the universal support 1511, so that the spherical head 1531 of the guide telescopic rod 153 can be slidably set in the spherical groove 1512 of the universal support 1511 on the concave slot 151, so that the concave slot 151 can rotate relative to the guide telescopic rod 153 through the sliding cooperation between the spherical head 1531 and the spherical groove 1512.

[0076] Combine Figure 11 In this way, the vertical roller 120 rotates in the concave groove 151, and the conveyor belt 400 deviates or collapses in the vertical direction, generating vertical pressure on the vertical roller 120, causing the vertical roller 120 to move vertically. At this time, the vertical movement of the vertical roller will abut against the concave groove 151, driving the concave groove 151 to move vertically synchronously, causing the concave groove 151 to rotate relative to the guide telescopic rod 153, ensuring that the extension center line of the guide limit groove 130 on the vertical roller 120 is always consistent with the extension center line of the side of the conveyor belt 400 after deviation, so that the conveyor belt 400 can be accurately corrected.

[0077] In coordination therewith, the elastic connecting member 140 is slidably and elastically connected to the concave slot 151 , so as to adjust the deviation of the conveyor belt 400 in the vertical direction.

[0078] Recombination Figure 9 and Figure 11Specifically, the elastic connector 140 includes a first elastic connector 1401 and a second elastic connector 1402, respectively arranged at both ends of the vertical roller 120. The first elastic connector 1401 and the second elastic connector 1402 are respectively hinged to a fixed support rod 142 passing through the vertical roller 120, and the first elastic connector 1401 and the second elastic connector 1402 are arranged in a trapezoidal distribution with the fixed support rod 142.

[0079] The first elastic connector 1401 and the second elastic connector 1402 have the same structure. Taking the first elastic connector 1401 as an example, the first elastic connector 1401 includes a rotating telescopic rod 143 and a rotating elastic tube 144. The rotating elastic tube 144 is hinged to the adjustment plate 113 and can rotate around the adjustment plate 113. The two ends of the concave slot 151 are respectively provided with waist-shaped grooves 1513 (such as Figure 10 ), one end of the rotating telescopic rod 143 passes through the waist-shaped groove 1513 and is hinged to the fixed support rod 142, and the other end is passed through the rotating elastic tube 144 and is elastically connected to the second elastic member 1441 (such as a spring) built into the rotating elastic tube 144.

[0080] In this way, the conveyor belt 400 deviates from the vertical roller 120 and generates vertical pressure, causing the vertical roller 120 to move vertically. The rotating telescopic rods 143 in the first elastic connector 1401 and the second elastic connector 1402 at both ends of the vertical roller 120 will be driven by the fixed support rod 142 to rotate and telescope synchronously in the waist-shaped groove 1513 of the concave slot 151, and the telescopic states of the corresponding rotating telescopic rods 143 in the first elastic connector 1401 and the second elastic connector 1402 are opposite.

[0081] Combine Figure 11 As an example, when the vertical roller 120 moves vertically toward the bottom surface of the conveyor belt 400 driven by the vertical offset of the conveyor belt 400, it will drive the rotating telescopic rod 143 in the first elastic connecting member 1401 and the second elastic connecting member 1402 to rotate synchronously in the waist-shaped groove 1513 of the concave slot 151 toward the direction close to the placement rack 100.

[0082] Since the first elastic connection member 1401 and the second elastic connection member 1402 are arranged in a trapezoidal distribution with the fixed support rod 142, when the rotating telescopic rod 143 in the first elastic connection member 1401 rotates toward the direction close to the placement frame 100, a lateral thrust will be generated on the rotating telescopic rod 143 in the first elastic connection member 1401, driving the rotating telescopic rod 143 in the first elastic connection member 1401 to move in the rotating elastic tube 144, and generating a compression force on the second elastic member 1441 in the rotating elastic tube 144, so that the second elastic member 1441 generates a force opposite to the lateral thrust on the rotating telescopic rod 143 under the action of its own elastic force and restoring force, driving the rotating telescopic rod 143 in the first elastic connection member 1401 to rotate in the direction away from the placement frame 100, thereby generating a thrust on the fixed support rod 142, and driving the vertical roller 120 to move vertically toward the top surface of the conveyor belt 400.

[0083] On the contrary, when the rotating telescopic rod 143 in the second elastic connecting member 1402 rotates toward the direction approaching the mounting frame 100, a lateral pulling force will be generated on the rotating telescopic rod 143 in the second elastic connecting member 1402, driving the rotating telescopic rod 143 in the second elastic connecting member 1402 to move in the rotating elastic tube 144, and generating a tensile force on the second elastic member 1441 in the rotating elastic tube 144, so that the second elastic member 1441 generates a force opposite to the lateral pulling force on the rotating telescopic rod 143 under the action of its own elastic restoring force, driving the rotating telescopic rod 143 in the second elastic connecting member 1402 to rotate in the direction away from the mounting frame 100, thereby generating a pulling force on the fixed support rod 142, and driving the vertical roller 120 to move vertically toward the top surface of the conveyor belt 400.

[0084] In this way, the telescopic rods 143 in the first elastic connector 1401 and the second elastic connector 1402 have opposite telescopic directions, which respectively generate thrust and pull on the vertical roller 120, thereby cooperating with each other to enable the vertical roller 120 to drive the conveyor belt 400 to move vertically, returning the conveyor belt 400 to its initial centerline position, and correcting the deviation in time to ensure the reliability of the vertical deviation correction.

[0085] At the same time, when the conveyor belt 400 is horizontally offset and the vertical roller 120 is driven to move laterally, the first elastic connecting member 1401 and the second elastic connecting member 1402 will move laterally synchronously with the guide connecting member 150, which will not affect the horizontal deviation correction of the conveyor belt 400 by the guide connecting member 150. The first elastic member 1541 in the guide connecting member 150 and the second elastic member 1441 in the elastic connecting member 140 will be compressed synchronously, and they will cooperate with each other to push the vertical roller 120 to move, thereby driving the conveyor belt 400 to return to its initial position.

[0086] Therefore, the correction device 100 constructed in this example ensures that the vertical roller 120 can cooperate with the conveyor belt 400 with different groove angles through the adjustment of the mounting frame 110, realizes the horizontal correction of the conveyor belt 400 through the guide connecting member 150, and realizes the vertical correction of the conveyor belt 400 through the elastic connecting member 140. At the same time, the relative rotation of the concave slot 151 can ensure that the extended center line of the guide limit slot 130 is always consistent with the extended center line of the side of the conveyor belt 400 after deviation, and can accurately correct the conveyor belt 400 to improve the correction effect.

[0087] The belt conveyor correction device provided by the present invention has a correction device 100 that is in elastic and dynamic contact with the conveyor belt 400, so that when the conveyor belt 400 deviates, it abuts against the guide limit groove 130 on the vertical roller 120, and the vertical roller 120 generates lateral pressure, so that the vertical roller 120 moves toward the placement frame 110, compressing the elastic connecting member 140, so that the vertical roller 120 generates a reverse thrust under the action of the elastic restoring force, pushing the conveyor belt back to the initial center line position, thereby realizing timely correction of the conveyor belt.

[0088] At the same time, the detection device 200 detects the lateral pressure value applied by the conveyor belt 400 to the vertical roller 120 in real time to obtain the deviation condition of the conveyor belt, and issues an alarm message to promptly remind the staff to ensure the reliability of the device.
