Description

Technical Field

[0001] This utility model relates to the field of conveying devices, specifically a conveyor belt conveyor and its correction device. Background Technology

[0002] like Figure 1 , Figure 2 As shown, the conveyor belt device typically includes a frame 11, a drive roller 12 and a driven roller 13 respectively disposed at both ends of the frame 11, and anti-deviation rollers 14 disposed on both sides of the frame 11. The conveyor belt 15 is wrapped around the outer ring of the two drive rollers 12 and the driven rollers 13. The drive rollers 12 are driven to rotate by a motor and drive the driven rollers 13 to rotate by friction between them and the conveyor belt 15, thereby realizing the conveying of materials. The frame 11 is equipped with idler rollers 16.

[0003] During material conveying, due to the imbalance of forces on the conveyor belt 15, it is easy for the conveyor belt 15 to deviate from its normal operating track after running for a period of time. The deviated conveyor belt 15 continuously rubs against the anti-deviation roller 14, causing it to wear easily. Therefore, professional personnel are required to adjust the deviated conveyor belt 15, a very complex process that causes significant inconvenience to the user. If it is not adjusted back in time, the side of the conveyor belt 15 will directly rub against the anti-deviation roller 14 and the frame 11, causing damage to the side of the conveyor belt 15 and rendering it unusable, leading to production line shutdown and impacting capacity. Utility Model Content

[0004] To address the above problems, this utility model provides a correction device for a conveyor belt conveyor, comprising: a base; a support assembly rotatably mounted on the base with the base as the center and extending to both sides of the base; and two guide wheel assemblies arranged in pairs, the two guide wheel assemblies being fixed to both ends of the support assembly respectively, the axial direction of the guide wheel assemblies being inclined relative to the extension direction of the support assembly and approaching the center of the support assembly.

[0005] According to this technical solution, when no conveyor belt deviation occurs, the conveyor belt runs between the two guide wheel assemblies without friction. When conveyor belt deviation occurs, the deviated side of the conveyor belt (e.g., the left side of the conveyor belt) abuts against the guide wheel assembly. The conveyor belt drives the left guide wheel assembly to rotate in the conveying direction. Since the support assembly is rotatably mounted on the base with the base as the center, the support assembly also rotates, causing the support assembly to tilt relative to its position when no conveyor belt deviation occurs. The distance between the two guide wheel assemblies decreases, causing the right guide wheel assembly of the conveyor belt to abut against the right side of the conveyor belt. Since the axial direction of the guide wheel assembly is tilted relative to the extension direction of the support assembly and moves closer to the center of the support assembly, when the guide wheel assembly abuts against the conveyor belt, it will generate a reverse force on the conveyor belt (e.g., when the conveyor belt deviates to the left, the guide wheel assembly drives the conveyor belt to move to the right; when the conveyor belt deviates to the right, the guide wheel assembly drives the conveyor belt to move to the left), and drive the conveyor belt back to its initial position, achieving deviation correction. This helps reduce conveyor belt friction and extend the service life of the conveyor belt. This invention can achieve correction without the need for other special correction devices. It has a simple structure, low cost, and is suitable for widespread use.

[0006] In an optional technical solution of this utility model, the base includes a first seat body, a connecting member, and a second seat body arranged sequentially.

[0007] The first base, the connector, and the second base are each provided with mounting holes corresponding to their positions.

[0008] The base also includes a pivot that passes through mounting holes in sequence and is perpendicular to the plane of the support assembly.

[0009] The connector is fixed at the middle of the support assembly.

[0010] According to this technical solution, the base has the advantages of simple structure, easy processing and manufacturing, and readily available materials.

[0011] In the optional technical solution of this utility model, both the first base and the second base are thrust bearings, and the inner ring of the thrust bearing is fixed to the rotating shaft.

[0012] According to this technical solution, the installation of the thrust bearing improves the flexibility of the support assembly's rotation.

[0013] In an optional technical solution of this utility model, the support component includes: a first base frame; a first idler assembly, a second idler assembly, and a third idler assembly sequentially and movably connected to the first base frame, the first idler assembly and the third idler assembly being symmetrically arranged at both ends of the second idler assembly; the end of the first idler assembly away from the second idler assembly is higher than the end where the first idler assembly is connected to the second idler assembly, and the end of the third idler assembly away from the second idler assembly is higher than the end where the third idler assembly is connected to the second idler assembly; or the support component includes a second base frame and a fourth idler assembly fixed to the second base frame.

[0014] According to this technical solution, the support components can be linear or U-shaped. Linear support components have the advantages of simple structure and ease of manufacturing. U-shaped support components, which are low in the middle and high at both ends, improve the ease of installation and allow the corresponding conveyor belt to accommodate more material. Technicians can choose the appropriate shape of the support component according to their needs.

[0015] In the optional technical solution of this utility model, the first base frame and / or the second base frame are made of round tubes.

[0016] According to the technical solution, the use of round tubes for the first and / or second base frames can reduce dust accumulation and facilitate cleaning.

[0017] This utility model also provides a conveyor belt conveyor, including a frame, a drive roller, a driven roller, and a conveyor belt. The drive roller and the driven roller are rotatably mounted at both ends of the frame. The conveyor belt is closely attached to the surfaces of the drive roller and the driven roller. The continuous movement of the conveyor belt is achieved by the rotation of the drive roller and the driven roller. It also includes the above-mentioned conveyor belt conveyor correction device, and the base is fixed to the frame.

[0018] In an optional technical solution of this utility model, multiple pairs of guide wheel assemblies are provided along the extension direction of the frame.

[0019] According to this technical solution, the extension direction of the frame is the conveying direction of the conveyor belt. Multiple pairs of guide wheel assemblies are set along the extension direction of the frame, which can correct the different positions of the conveyor belt, improve the correction effect, and reduce the risk of the conveyor belt deviating and failing to return to the correct position.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 3 , Figure 4 and Figure 5As shown, this utility model provides a belt conveyor correction device, including: a base 2; a support component 3 and two guide wheel assemblies 4 arranged in pairs. The support component 3 is rotatably mounted on the base 2 with the base 2 as the center and extends to both sides of the base 2. The two guide wheel assemblies 4 are respectively fixed to both ends of the support component 3. The axial direction of the guide wheel assembly 4 is inclined relative to the extension direction of the support component 3 and approaches the middle of the support component 3.

[0035] Through the above methods, such as Figure 4 As shown, when no conveyor belt 5 deviates, the conveyor belt 5 runs between the two guide wheel assemblies 4 and does not rub against the guide wheel assemblies 4; as Figure 8 As shown, when conveyor belt 5 deviates, the deviated side of conveyor belt 5 (such as the left side of conveyor belt 5) abuts against guide wheel assembly 4. Conveyor belt 5 drives the left guide wheel assembly 4 to rotate in the conveying direction. Since support assembly 3 is rotatably mounted on base 2 with base 2 as the center, support assembly 3 also rotates, causing support assembly 3 to tilt relative to its position when conveyor belt 5 is not deviating. The distance between the two guide wheel assemblies 4 decreases, causing the right guide wheel assembly 4 of conveyor belt 5 to abut against the right side of conveyor belt 5. Since the axial direction of guide wheel assembly 4 is tilted relative to the extension direction of support assembly 3 and moves closer to the middle of support assembly 3, when guide wheel assembly 4 abuts against conveyor belt 5, it will generate a reverse force on conveyor belt 5 (e.g., when conveyor belt 5 deviates to the left, guide wheel assembly 4 drives conveyor belt 5 to move to the right; when conveyor belt 5 deviates to the right, guide wheel assembly 4 drives conveyor belt 5 to move to the left), and drive conveyor belt 5 to return to its initial position, thus correcting the deviation. This helps reduce friction of conveyor belt 5 and extend its service life. This invention can achieve correction without the need for other special correction devices. It has a simple structure, low cost, and is suitable for widespread use.

[0036] Specifically, such as Figure 3 , Figure 5 and Figure 7 As shown, the conveyor belt conveyor includes a frame 6, a drive roller 7, a driven roller 8, and a conveyor belt 5. The drive roller 7 and the driven roller 8 are rotatably mounted at both ends of the frame 6. The conveyor belt 5 is closely attached to the surfaces of the drive roller 7 and the driven roller 8. The continuous movement of the conveyor belt 5 is achieved by the rotation of the drive roller 7 and the driven roller 8. The base 2 is fixed to the frame 6.

[0037] refer to Figure 6 When the conveyor belt 5 is working normally, it is perpendicular to the frame 6. At this time, there is a certain distance between the guide wheel assembly 4 and the conveyor belt 5, and the distance B between the guide wheel assemblies on both sides is greater than the width of the conveyor belt 5. When the conveyor belt 5 deviates to the left (see...), Figure 8The guide wheel assembly 4 on the left side comes into contact with the guide wheel assembly 4 on the left side. The conveyor belt 5 drives the guide wheel assembly 4 on the left side to rotate in the direction of the conveyor belt movement. The support assembly 3 is at a certain angle to the frame 6. The vertical distance B1 between the guide wheel assemblies on both sides gradually decreases. The correction device adjusts the conveyor belt 5 to the center of the frame. As the distance B1 between the guide wheels on both sides gradually decreases, the guide wheel assemblies on the other side also come into contact with the other side of the conveyor belt 5. The correction device reverses and the vertical distance B1 between the guide wheel assemblies gradually increases. The conveyor belt 5 no longer comes into contact with the guide wheel assembly 4. The support assembly 3 returns to its original position, and the conveyor correction is completed.

[0038] In a preferred embodiment of this utility model, the base 2 includes a first seat 21, a connector 22, and a second seat 23 arranged sequentially. The first seat 21, connector 22, and second seat 23 each have corresponding mounting holes. The base 2 also includes a rotating shaft 24, which passes through the mounting holes sequentially and is perpendicular to the plane of the support assembly 3. The connector 22 is fixed to the middle of the support assembly 3. In this embodiment, the base 2 has the advantages of simple structure, ease of processing and manufacturing, and readily available materials. Specifically, the rotating shaft 24 can be a bolt, and the base 2 also includes a fixing member 25, which is screwed and positioned to the rotating shaft 24.

[0039] In a preferred embodiment of this invention, both the first base 21 and the second base 23 are thrust bearings, and the inner ring of the thrust bearing is fixed to the rotating shaft 24. This method improves the flexibility of the support assembly 3's rotation by providing thrust bearings.

[0040] It should be noted that the form of the base 2 is not limited to the example given in this embodiment. Any form that can be connected to the support component 3 and drive the support component 3 to rotate in the plane where the conveyor belt 5 is located can be applied to this utility model.

[0041] In a preferred embodiment of this utility model, the support assembly 3 includes: a first base frame 30; a first idler assembly 31, a second idler assembly 32, and a third idler assembly 33 sequentially and movably connected to the first base frame 30, wherein the first idler assembly 31 and the third idler assembly 33 are symmetrically arranged at both ends of the second idler assembly 32; the end of the first idler assembly 31 away from the second idler assembly 32 is higher than the end where the first idler assembly 31 is connected to the second idler assembly 32, and the end of the third idler assembly 33 away from the second idler assembly 32 is higher than the end where the third idler assembly 33 is connected to the second idler assembly 32; or the support assembly 3 includes a second base frame (not shown) and a fourth idler assembly (not shown) fixed to the second base frame.

[0042] Through the above methods, the support component 3 can be linear or U-shaped. The linear support component 3 has the advantages of simple structure and easy manufacturing. The U-shaped support component 3, which is low in the middle and high at both ends, improves the convenience of installation and allows the corresponding conveyor belt 5 to accommodate more material. Technicians can choose the appropriate shape of the support component 3 as needed. In this embodiment, the first base frame 30 is U-shaped, the second base frame is linear, and the first idler assembly 31, the second idler assembly 32, and the third idler assembly 33 are rotatably distributed along the axial direction of the first base frame 30. The fourth idler assembly is rotatably mounted on the second base frame along its axial direction. In this embodiment, the idler assembly includes an idler bracket and an idler body. The idler body is rotatably mounted on the idler bracket. The form of the idler bracket is not limited in this embodiment.

[0043] In a preferred embodiment of this invention, the first base frame and / or the second base frame are made of round tubing. Using round tubing for the first base frame and / or the second base frame reduces dust accumulation and facilitates cleaning.

[0044] In this embodiment of the invention, the guide wheel assembly 4 includes a guide wheel and a guide wheel bracket. The guide wheel bracket enables the guide wheel to rotate in the manner described in this embodiment and drive the conveyor belt to correct its deviation. This embodiment does not limit the specific form of the guide wheel bracket.

[0045] In a preferred embodiment of this invention, multiple pairs of guide wheel assemblies 4 are arranged along the extension direction of the frame 6. The extension direction of the frame 6 is the conveying direction of the conveyor belt 5. The multiple pairs of guide wheel assemblies 4 arranged along the extension direction of the frame can correct the deviation of the conveyor belt 5 at different positions, improve the correction effect, and reduce the risk that the conveyor belt 5 will deviate and fail to return to its correct position.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
