Description

Technical Field

[0001] The utility model relates to the technical field of logistics and transportation, in particular to a deviation-correcting mechanism for a belt conveyor. Background Art

[0002] Belt conveyors transport materials via belts. However, due to factors such as design, installation quality, environment, belt tension, and material conveying conditions, belt deviation is common in practical applications. Existing deviation correction methods typically require human intervention, but this untimely intervention can still lead to the risk of belt damage, and stopping the machine for correction will undoubtedly reduce belt conveyor efficiency. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a belt conveyor deviation correction mechanism, which effectively solves the problem of belt deviation without stopping the machine.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a belt conveyor correction mechanism, including

[0005] Fixed seat, fixedly installed on the belt conveyor;

[0006] A deviation-correcting frame, the middle portion of which is rotatably arranged on the fixed seat;

[0007] A conveying assembly comprising two rotating rollers symmetrically arranged on the deflection correction frame along the length direction of the deflection correction frame, wherein the upper ends of the two rotating rollers support the belt;

[0008] A correction component, a correction platform symmetrically arranged on both sides of the conveying component along the length direction of the correction frame; the correction platform is fixed to the correction frame, and a correction slope for the belt to contact is provided on the side facing the conveying component, the correction slope gradually rises from close to the conveying component to the direction away from the conveying component, and the highest point of the correction slope is higher than the height of the upper end surface of the rotating drum.

[0009] When installing the belt conveyor correction mechanism on the belt conveyor, the length direction of the correction frame should be arranged perpendicular to the conveying direction of the belt, and the width of the belt supported by the two rotating rollers should be kept the same, that is, the middle of the belt should be located in the same vertical plane as the middle of the correction frame. At this time, the belt is in a state of not deviating. When the belt is conveyed, the correction frame will not rotate along the fixed seat because the forces on both sides of the correction frame are balanced. When the belt starts to deviate (that is, the belt gradually deviates to one side of the correction frame), the belt will stop running. The end of the belt will abut against the correcting inclined surface of the correcting table located on one side of the correcting frame. At this time, as the belt continues to be transmitted, the belt abutting against the correcting inclined surface will exert a force on the correcting inclined surface along its conveying direction, which will cause the forces on both sides of the correcting frame to be unbalanced (one side is under force, and the other side is not under force). At this time, the correcting frame rotates. Due to the rotation of the correcting frame, the conveying direction of the belt on the rotating drum changes immediately, and then a force can be generated on the belt on the rotating drum in the opposite direction of the deviation direction to correct the deviation of the belt.

[0010] The beneficial effects of the belt conveyor correction mechanism of the utility model are:

[0011] The correcting inclined surface can stop the belt in the process of deviation, thereby preventing it from further deviation. At the same time, the force exerted by the correcting inclined surface drives the correcting frame to rotate, thereby changing the conveying direction of the rotating drum. The rotating drum then adjusts the conveying direction of the belt to achieve automatic belt deviation correction. The belt conveyor correcting mechanism of this utility model can automatically correct the belt without the need for additional power, ensuring the timeliness and reliability of the correction operation.

[0012] Furthermore, the correction frame includes a frame body, and the frame body is provided with a first mounting seat, a middle mounting seat, and a second mounting seat in sequence along the length direction of the correction frame. A first mounting area for mounting one of the rotating rollers is formed between the first mounting seat and the middle mounting seat, and a second mounting area for mounting another rotating roller is formed between the second mounting seat and the middle mounting seat.

[0013] It should be noted that the middle mounting seat is located in the middle of the frame body, and the first mounting area and the second mounting area are at the same distance along the length of the correction frame, so as to ensure that the two rotating rollers are symmetrically arranged with the middle of the frame body as the symmetry center.

[0014] Furthermore, the upper end surface of the middle mounting seat is lower than the upper end surface of the rotating drum in order to avoid as much as possible the resistance to the belt caused by the middle mounting seat contacting the belt during the transmission process between the two rotating drums.

[0015] Furthermore, the deflection correction platform is arranged on the first mounting seat and the second mounting seat one by one; the deflection correction inclined surface is a circular arc inclined surface. The arrangement of the circular arc inclined surface can adapt to the circular arc surface of the rotating drum, thereby facilitating the transmission of the circular arc inclined surface to the belt during the deflection correction process.

[0016] Furthermore, the deflection-correcting inclined surface is provided with at least one abutting boss for the belt to contact, so as to increase the friction resistance between the deflection-correcting inclined surface and the belt.

[0017] Specifically, the fixed seat includes a base, to which a bearing seat located below the correction frame is connected. A bearing capable of being embedded in the bearing seat is provided at the center of the lower end of the correction frame. The rotation of the correction frame relative to the base is achieved through the cooperation between the bearing seat and the bearing.

[0018] Furthermore, the base is provided with a stopper for limiting the rotation angle of the correcting frame. The stopper comprises two stopper holes formed on the base perpendicular to the conveying direction of the belt. Positioning pins are inserted into the stopper holes to stop the correcting frame from rotating. During the correcting frame's rotation, the stopper pins prevent the correcting frame from rotating, thereby limiting its maximum rotational range.

[0019] Furthermore, the limiting portions are provided in multiple groups, and the groups are sequentially arranged on the base along the conveying direction of the belt. During use, the positioning pin is inserted into only one group of limiting portions. By providing multiple groups of limiting portions, the maximum rotation range of the correction frame can be adjusted according to actual needs.

[0020] Furthermore, the fixing seat further includes a connecting frame fixed to the belt conveyor in a direction perpendicular to the belt conveying direction; the seat body is arranged along the belt conveying direction and is provided with a through hole for the connecting frame to pass through, so as to facilitate the connection between the fixing seat and the belt conveyor.

[0021] Furthermore, the rotating drum includes a roller shaft and a roller sleeved on the roller shaft. The roller shaft is fixedly mounted on the deviation correction frame, and the roller can rotate along the roller shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0035] Example

[0036] See attached Figure 1-3 As shown, a belt conveyor correction mechanism of the present invention includes a fixed seat 1, a correction frame 2, a transmission component 3, and a correction component 4, wherein the fixed seat 1 is fixedly mounted on the belt conveyor 5. The middle part of the correction frame 2 is rotatably set on the fixed seat 1. The transmission component 3 includes two rotating rollers 31 symmetrically arranged on the correction frame 1 along the length direction of the correction frame, and the upper ends of the two rotating rollers 31 support the belt 51. The correction component 4 is symmetrically arranged on both sides of the transmission component 3 along the length direction of the correction frame. The correction platform 41 is fixedly connected to the correction frame 2, and a correction bevel 42 for the belt 51 to contact is provided on the side facing the transmission component 3. The correction bevel 42 gradually rises from close to the transmission component 4 to away from the transmission component 4, and the highest point of the correction bevel 42 is higher than the height of the upper end surface of the rotating roller 31.

[0037] When the belt conveyor correction mechanism is installed on the belt conveyor 5, the length direction of the correction frame 2 should be arranged perpendicular to the conveying direction of the belt 51, and the width of the belt 51 supported by the two rotating rollers 31 should be kept the same, that is, the middle of the belt 51 should be located in the same vertical plane as the middle of the correction frame 2. At this time, the belt 51 is in a non-deflected state. When the belt 51 is conveyed, the correction frame 2 will not rotate along the fixed seat 1 due to the balanced force on both sides of the correction frame 2. When the belt 51 starts to deviate (that is, the belt 51 gradually deviates to one side of the correction frame 2), the belt 51 The end portion will abut against the correcting inclined surface 42 of the correcting platform 41 located on one side of the correcting frame 2. At this time, as the belt 51 continues to convey, the belt 51 abutting against the correcting inclined surface 42 will generate a force on the correcting inclined surface 42 along its conveying direction, thereby causing the two sides of the correcting frame 2 to be subjected to unbalanced force (one side is subjected to force, and the other side is not subjected to force). At this time, the correcting frame 2 immediately rotates. Due to the rotation of the correcting frame 2, the conveying direction of the belt 51 by the rotating drum 31 immediately changes, thereby forming a force on the belt 51 located on the rotating drum 31 in the opposite direction of the deviation direction to correct the deviation of the belt 51.

[0038] For example, Figure 4 As shown, when the belt 51 deviates to the left, the belt 51 will exert a force on the correcting platform 41 on the left side of the correcting frame 2, thereby causing the correcting frame 2 to rotate counterclockwise. At this time, the rotating roller 31 generates a friction force tilted to the right on the belt 51 due to the rotation of the correcting frame 2, thereby driving the belt 51 to correct the deviation to the right during the transmission process.

[0039] In this embodiment, the belt 51 can be stopped during the deviation process by setting the correction bevel 42 to suppress further deviation of the belt 51. At the same time, the force exerted by the correction bevel 42 is used to drive the correction frame 2 to rotate, so that the conveying direction of the rotating drum 31 changes, and then the conveying direction of the belt 51 is adjusted by the rotating drum 31 to realize unpowered automatic correction of the belt 51.

[0040] In some embodiments, see Appendix Figure 5 As shown, the deflection correction frame 2 includes a frame body 21, which is provided with a first mounting seat 22, a middle mounting seat 23, and a second mounting seat 24 in sequence along its length. A first mounting area for mounting one rotating roller 31 is formed between the first mounting seat 22 and the middle mounting seat 23, while a second mounting area for mounting another rotating roller 31 is formed between the second mounting seat 24 and the middle mounting seat 23. It is important to note that the middle mounting seat 23 is located in the middle of the frame body 21, and the first and second mounting areas are equidistant along the length of the deflection correction frame. This ensures that the two rotating rollers 31 are symmetrically arranged with the middle of the frame body 21 as the center of symmetry.

[0041] Furthermore, the upper end surface of the middle mounting seat 23 is lower than the upper end surface height of the rotating drum 31. This arrangement can minimize the contact of the belt 51 with the middle mounting seat 23 when the two rotating drums 31 support the belt 51, thereby preventing the middle mounting seat 23 from exerting resistance on the belt 51.

[0042] In some embodiments, see Appendix Figure 3 As shown, the deflection correction platform 41 is arranged one by one on the first mounting seat 22 and the second mounting seat 24, and the deflection correction platform 41 is located on the side of the first mounting seat 22 or the second mounting seat 24 facing the rotating drum 31. When the belt 51 deviates, the end of the belt 51 can directly enter the deflection correction bevel 42 of the deflection correction platform 41 from the rotating drum 31. Furthermore, the deflection correction bevel 42 is a circular arc-shaped bevel, and the curvature of the circular arc-shaped bevel is consistent with the curvature of the circular arc surface of the rotating drum 31. This arrangement ensures that when the belt 51 enters the deflection correction bevel 42 from the rotating drum 31 or enters the rotating drum 31 from the deflection correction bevel 42, the belt 51 can be stably transported along the deflection correction bevel 42 or the rotating drum 31.

[0043] Furthermore, in order to enhance the stopping effect of the correcting bevel 42 on the belt 51 from deviating, in some embodiments, at least one abutment boss for the belt 51 to contact is provided on the correcting bevel 42. The abutment boss increases the frictional resistance between the correcting bevel 42 and the belt 51 to avoid slipping of the belt 51 on the correcting bevel 42.

[0044] In some embodiments, see Appendix Figure 6 As shown, the fixed base 1 includes a base 11, to which is connected a bearing seat 12 located below the correction frame 2. A bearing is provided in the middle of the lower end of the correction frame 2, which can be embedded in the bearing seat 12. The cooperation between the bearing seat 12 and the bearing enables the correction frame 2 to rotate relative to the base 11.

[0045] In some embodiments, a limiting portion is provided on the base 11 for limiting the rotation angle of the correction frame 2. The limiting portion includes two limiting holes 13 provided on the base 11 perpendicular to the belt conveyor direction, and a positioning pin is inserted into the limiting hole 13 for stopping the rotation of the correction frame 2. During the rotation of the correction frame 2, when the correction frame 2 rotates clockwise, the correction frame 2 can abut against one positioning pin, and when the correction frame 2 rotates counterclockwise, the correction frame 2 can abut against another positioning pin. The maximum rotation range of the correction frame 2 can be limited by the positioning pins stopping the correction frame 2. It should be noted that when the correction frame 2 is not rotating (that is, the length direction of the correction frame 2 is perpendicular to the belt conveyor direction), a spacing is left between the positioning pins and the correction frame 2 for the correction frame 2 to rotate.

[0046] Furthermore, multiple sets of limiters are provided, and the multiple sets of limiters are sequentially arranged on the base along the conveying direction of the belt. During use, the positioning pin 14 is inserted into only one set of limiters, and the provision of multiple sets of limiters allows the maximum rotation range of the correcting frame 2 to be adjusted according to actual needs.

[0047] In some embodiments, the fixed base 1 further includes a connecting bracket 15 secured to the belt conveyor 5 perpendicular to the belt conveying direction. The base 11 is arranged along the belt conveying direction and has a through hole for the connecting bracket 15. The provision of the connecting bracket 15 enhances the structural strength of the fixed base 1 perpendicular to the belt conveying direction, ensuring a stable connection between the fixed base 1 and the belt conveyor 5.

[0048] In some embodiments, the rotating drum 31 adopts the unpowered correction roller in the prior art, which includes a roller shaft and a roller sleeved on the roller shaft. The roller shaft is fixedly installed on the correction frame, and the roller can rotate along the roller shaft.

[0049] The above implementation methods are only for illustrating the technical concept and features of the utility model. Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
