[0028] The embodiments of the present application are described in detail below, examples of which are shown in the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0029] As shown in the drawings, Figure 1 The belt deviation rectifying device 100 of the embodiment of the present application comprises a mounting frame 1, a clamping assembly 2 and a driving device 3. The mounting frame 1 is connected with the frame 202 of the belt conveyor 200. The clamping assembly 2 is movably connected with the mounting frame 1 along the width direction of the belt 201. The driving device 3 is connected with the mounting frame 1. The driving device 3 is used to drive the clamping assembly 2 to move along the width direction of the belt 201.

[0030] The belt deviation rectifying device 100 of the embodiment of the present application is suitable for rectifying the deviation of the belt 201 of the belt conveyor 200. When the belt 201 of the belt conveyor 200 deviates, the clamping assembly 2 is first used to clamp the belt 201, and then the driving device 3 is used to drive the clamping assembly 2 to move outward along the width direction of the belt conveyor 200. The belt 201 can be pulled to one side along the width direction, so as to rectify the deviation of the belt 201 and ensure the normal operation of the belt conveyor 200.

[0031] The belt deviation rectifying device 100 of the embodiment of the present application can quickly rectify the position of the belt 201 through the driving device 3 when rectifying the belt 201, so as to improve the rectifying efficiency and the conveying efficiency of the belt conveyor 200.

[0032] It can be understood that the outward movement refers to the movement from the center to the edge of the belt 201 along the width direction of the belt 201.

[0033] As shown in the drawings, Figure 1As shown, the belt conveyor 200 comprises a belt 201, a frame 202 and a plurality of groove-shaped roller sets 203, the groove-shaped roller sets 203 are evenly arranged along the length direction of the frame 202, the distance between two adjacent groove-shaped roller sets 203 is 4m-6m; the belt 201 is arranged on the upper side of the groove-shaped roller sets 203, the groove-shaped roller sets 203 comprise a flat roller and two side rollers, the flat roller and the two side rollers form a groove-shaped structure, which can increase the contact area of the material and the conveying belt and improve the conveying efficiency.

[0034] As an example, as shown in the drawings, Figure 1 As shown, the shape of the belt 201 matches the shape of the groove-shaped roller set 203, the belt 201 is divided into a flat belt part 2011 and two side belt parts 2012 along the width direction of the belt 201, and the two side belt parts 2012 are arranged on the two sides of the flat belt part 2011 and are inclined upward; the clamping assembly 2 is arranged at the edge of the belt 201 and can be clamped on the side belt part 2012, and the clamping assembly 2 is movable along the inclination direction of the side belt part 2012.

[0035] In some embodiments, the number of clamping assemblies 2 is multiple, at least one clamping assembly 2 is a first clamping assembly, at least one clamping assembly 2 is a second clamping assembly, and the first clamping assembly and the second clamping assembly are oppositely arranged on the two sides of the belt 201 along the width direction of the belt 201.

[0036] The first clamping assembly and the second clamping assembly are respectively used for clamping the two side belt parts 2012 of the belt 201, which can pull the belt 201 to both sides along the width direction of the belt 201, thereby realizing the deviation correction of the belt 201 in two directions.

[0037] For example, when the belt 201 deviates towards the first clamping assembly, the edge of the belt 201 close to the first clamping assembly moves upward along the side roller, and the edge of the belt 201 close to the second clamping assembly moves downward along the side roller, at this time, the edge of the side belt 201 can be pulled to the outside of the belt conveyor 200 by the second clamping assembly, so that the belt 201 is reset.

[0038] It can be understood that each clamping assembly 2 is correspondingly provided with a driving device 3, in other words, the driving device 3 can drive the clamping assembly 2 to move alone, so that the clamping assembly 2 can act alone.

[0039] Optionally, the first clamping assembly and the second clamping assembly form a deviation correction group, and the number of deviation correction groups is multiple, and the multiple deviation correction groups are arranged at intervals along the length direction of the belt 201.

[0040] Therefore, multiple correction groups can perform correction work along the entire length of belt 201. When a section of belt 201 deviates, the correction group located near that section can perform correction work on belt 201, thereby quickly correcting belt 201 and keeping belt conveyor 200 working normally.

[0041] Furthermore, when the belt 201 deviates significantly, multiple first clamping components or multiple second clamping components arranged adjacent to each other can simultaneously clamp the belt 201, thereby applying greater tension to the belt 201 and enabling the belt 201 to quickly return to its original position.

[0042] It is understood that those skilled in the art can install the belt correction assembly in a suitable area of ​​the frame 202, such as the bend of the belt 201, the head and tail rollers of the belt conveyor 200, or other areas where belt 201 is prone to deviation, depending on the application scenario of the belt conveyor 200.

[0043] In some embodiments, the belt alignment device 100 further includes a slide 4, which is movably connected to the mounting frame 1 along the width direction of the belt 201, and the clamping assembly 2 is movably connected to the slide 4 along the length direction of the belt 201.

[0044] With the above settings, the clamping assembly 2 can move in both the width and length directions of the belt 201. When the belt 201 deviates from its original direction, the clamping assembly 2 clamps the belt 201, and the drive device 3 moves the slide 4 to the outside of the belt conveyor 200, thereby pulling the belt 201 outward in the opposite direction of its width to correct the belt 201's deviation. At the same time, the belt 201 continues to convey, and the clamping assembly 2 can move relative to the slide 4 as the belt 201 is conveyed, thereby achieving non-stop deviation correction of the belt 201, further reducing the impact of the deviation correction action on the belt 201, and improving the conveying efficiency of the belt conveyor 200.

[0045] As an example, such as Figure 1 As shown, the mounting frame 1 includes a base frame 11 and a guide frame 12. The base frame 11 is fixedly connected to the frame 202 of the belt conveyor 200 by means of threaded connection or welding. The guide frame 12 is located on the upper side of the base frame 11. The guide frame 12 includes two guide rails. The two guide rails are arranged at intervals along the length direction of the belt 201. The guide rails extend along the inclined direction of the side belt 2012. The two guide rails are connected to each other to ensure the stability of the guide frame 12.

[0046] The slide 4 is long and extends along the length of the belt 201. The clamping assembly 2 is slidably connected to the slide 4 along the length of the belt 201. Two guide blocks 41 are fixedly connected to the slide 4. The two guide blocks 41 are slidably engaged with the two guide rails respectively, so as to realize the sliding connection between the slide 4 and the mounting bracket 1. The driving device 3 is located between the two guide rails. The driving device 3 can drive the slide 4 to move outward along the inclined direction of the side belt 2012, thereby pulling the belt 201 outward, so as to realize the belt 201 correction work.

[0047] In some embodiments, the carriage 4 has a first sliding structure, the clamping assembly 2 has a second sliding structure, and the first sliding structure and the second sliding structure are slidably engaged.

[0048] With the above settings, a stable connection between the clamping component 2 and the slide 4 can be achieved, so that when the clamping component 2 clamps the belt 201, it can move along with the belt 201 during conveying.

[0049] As an example, such as Figure 1 As shown, the carriage 4 has a sliding groove 42, and the clamping assembly 2 has a slider 21. The slider 21 is slidably engaged with the sliding groove 42, thereby achieving a stable sliding connection between the clamping assembly 2 and the carriage 4. The sliding groove 42 forms the first sliding structure described above, and the slider 21 forms the second sliding structure described above.

[0050] In some embodiments, a spring member 43 is provided between the clamping assembly 2 and the slide 4. The spring member 43 is used to apply a spring force to the clamping assembly 2 along the length direction of the belt 201 so that the relative position of the clamping assembly 2 and the slide 4 tends to remain unchanged.

[0051] During the belt 201 correction process, the clamping component 2 moves along the length of the belt 201 as the belt 201 is conveyed. When the belt 201 correction work is completed, the clamping component 2 releases the belt 201. At this time, under the action of the elastic element 43, the clamping component 2 moves in the opposite direction of the belt 201 and resets, so that the next correction work can be carried out.

[0052] Optionally, the elastic element 43 is a spring.

[0053] As an example, such as Figure 1 As shown, the spring is located in the slide groove 42, and the two ends of the spring are respectively connected to the slider 21 and the groove wall of the slide groove 42. The spring is telescopic along the length of the belt 201. When the clamping assembly 2 moves with the belt 201, the slider 21 moves away from the spring and the spring is stretched. When the clamping assembly 2 releases the belt 201, the spring applies a spring force to the slider 21, causing the clamping assembly 2 to move closer to the spring, so as to realize the reset of the clamping assembly 2.

[0054] In some embodiments, the clamping component 2 is an electric gripper.

[0055] Electric grippers have advantages such as small size, which can reduce the space occupied by the correction device, thereby reducing the impact of the correction device on the belt conveyor 200.

[0056] Of course, in other embodiments, the clamping component 2 may also be a pneumatic gripper.

[0057] As an example, such as Figure 1 As shown, the clamping component 2 is used to clamp the side belt portion 2012. The distance between the edge of the clamping component 2 near the flat belt portion 2011 and the edge of the side belt portion 2012 away from the flat belt portion 2011 is d, and the width of the side belt portion 2012 is L, where d ≥ 1 / 2L. Therefore, it can be ensured that the clamping component 2 can still clamp the belt 201 when the belt 201 deviates by a large distance.

[0058] In some embodiments, the clamping assembly 2 includes a first gripper 22 and a second gripper 23 that are movably positioned relative to each other, and both the first gripper 22 and the second gripper 23 are provided with rubber pads 221 on their relatively close sides.

[0059] The rubber pad 221 can increase the friction between the first gripper 22 and the second gripper 23 and the belt 201, so that the first gripper 22 and the second gripper 23 can clamp the belt 201 tightly without damaging the belt 201.

[0060] In some embodiments, the drive device 3 is a telescopic drive member.

[0061] By setting the drive device 3 as a telescopic drive component, such as a cylinder, hydraulic cylinder, electric push rod, etc., the clamping assembly 2 can move rapidly along the width direction of the belt 201, thereby achieving rapid correction of the belt 201 and improving the correction efficiency.

[0062] As an example, such as Figure 1 As shown, the cylinder of the telescopic drive is connected to the base frame 11, and the telescopic rod of the telescopic drive is connected to the slide 4; thus, the reciprocating movement of the clamping assembly 2 can be realized through the telescopic drive.

[0063] In some embodiments, the belt correction device 100 further includes a sensor 5 for monitoring whether the belt 201 is misaligned, and the telescopic drive and the electric gripper are both electrically connected to the sensor 5.

[0064] When sensor 5 detects that belt 201 is misaligned, it can send a signal to the electric gripper and telescopic drive component at the corresponding position. After receiving the signal, the electric gripper starts to move and clamps belt 201. After receiving the signal, the electric gripper starts to move outward, thereby pulling the edge of belt 201 outward, thus realizing the belt 201 misalignment correction.

[0065] Optionally, all 5 sensors are laser sensors. The laser sensors are located on the lower side of the side belt portion 2012 of the belt 201, and are arranged near the edge of the side belt portion 2012 away from the flat belt portion 2011. The emitting end of the laser sensor is arranged facing the belt 201.

[0066] Therefore, the laser sensor can emit light towards the belt 201. After the light is reflected by the belt 201, it is received by the laser sensor, which can monitor the position of the edge of the belt 201 and thus determine whether the belt 201 is running off track.

[0067] When belt 201 does not deviate, the projection of belt 201 on the horizontal plane can cover the laser sensor. At this time, belt 201 can reflect the light emitted by the laser sensor. The laser sensor can receive the light reflected by belt 201, so it is determined that belt 201 has not deviated and clamping component 2 does not work.

[0068] When belt 201 deviates from its designated path, the edge of belt 201 shifts to one side along the width direction of belt 201, causing the projection of belt 201 on the horizontal plane to not cover the laser sensor. At this time, the laser sensor cannot receive the emitted light, and it is determined that belt 201 has deviated from its designated path. The sensor then sends a signal to the electric gripper and telescopic drive component at the corresponding position, and the clamping assembly 2 operates to correct the deviation of belt 201.

[0069] As an example, such as Figure 1 As shown, sensor 5 is set vertically upward, meaning that sensor 5 can emit light vertically upward; there are multiple sensors 5, at least one sensor 5 is a first sensor 5, and at least one sensor 5 is a second sensor 5. The first sensor 5 is set in correspondence with the first clamping assembly, and the second sensor 5 is set in correspondence with the second clamping assembly; the first sensor 5 and the first clamping assembly are located on one side of the belt 201, and the second sensor 5 and the second clamping assembly are located on the other side of the belt 201.

[0070] Of course, in other embodiments, those skilled in the art can make adaptive adjustments to the installation position of the sensor 5 and the direction of the light emitted by the sensor 5 according to the structure of the belt conveyor 200, so as to improve the accuracy of detecting belt misalignment.

[0071] In some embodiments, both sensor 5 and clamping assembly 2 are connected to the mounting bracket 1.

[0072] With the above settings, the sensor 5 and the clamping assembly 2 can be pre-connected to the mounting frame 1, and then the mounting frame 1 can be connected to the frame 202 of the belt conveyor 200, thereby improving the ease of installation of the belt correction device 100.

[0073] As an example, such as Figure 1 As shown, sensor 5 is connected to base frame 11 via sensor 5 bracket 51. Two sensors 5 are correspondingly set in clamping component 2. The two sensors 5 are arranged on both sides of clamping component 2 along the length of belt 201. The sensor 5 and clamping component 2 are staggered to prevent clamping component 2 from blocking sensor 5, so that the light emitted by sensor 5 can reach the height of belt 201, and at the same time improve the monitoring accuracy of sensor 5.
