Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a conveyor belt correction tool and belt conveyor. Background Technology

[0002] Belt conveyors, also known as belt conveyors or rubber belt conveyors, are continuous transport devices with traction. Their working principle involves a motor or other power source driving a rotating drum, which in turn moves a conveyor belt, thus transporting materials from one location to another. Belt conveyors have a wide range of applications, primarily in industries such as coal, mining, building materials, chemicals, petroleum, and transportation.

[0003] When workers use belt conveyors to transport materials, they place the materials steadily at the feed end of the belt conveyor, then start the belt conveyor motor to make the rollers start rotating, which in turn drives the conveyor belt to move. When the materials are transported to the unloading end of the conveyor belt, they will be unloaded to the target position, thus completing one transport cycle of materials.

[0004] Due to differences in materials or issues with material placement, the load on the conveyor belt may be uneven. During operation, the conveyor belt may deviate from its designated path, causing materials to fall off the edge of the belt and resulting in material loss.

[0005] Therefore, there is an urgent need for a conveyor belt correction tool and belt conveyor to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to provide a conveyor belt correction fixture and belt conveyor, which can solve the problem that when a belt conveyor is conveying materials, the load on the conveyor belt is uneven due to different material weights or material placement issues, causing the conveyor belt to easily run off-track, resulting in materials falling off the edge of the conveyor belt and causing material loss.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] On the one hand, this utility model provides a conveyor belt correction fixture for correcting the deviation of the conveyor belt in a belt conveyor. The conveyor belt correction fixture includes:

[0009] A drive unit and a lead screw, wherein the output end of the drive unit is connected to the lead screw; the lead screw is parallel to the length direction of the conveyor belt;

[0010] A movable block and a connector, the movable block being threadedly connected to the lead screw, and the connector being connected to the movable block and one of the belt rollers of the conveyor belt;

[0011] A first induction switch and a second induction switch, the first induction switch and the second induction switch are respectively located on both sides of the conveyor belt in the width direction and both send lasers to the side surface of the conveyor belt. The first induction switch and the second induction switch are both electrically connected to the driving member. The first induction switch can control the driving member to rotate forward, and the second induction switch can control the driving member to rotate backward.

[0012] As a preferred technical solution of the conveyor belt deviation rectification tooling, the conveyor belt deviation rectification tooling further includes a fixed frame. Side plates are respectively provided on both sides of the conveyor belt in the width direction. The fixed frame is fixedly connected to the side plates. The fixed frame has an opening. The driving member is connected to the side wall of the opening. The lead screw is placed in the opening. Through holes are provided on both opposite side walls of the opening. The two through holes are arranged oppositely. Bearings are provided in both of the two through holes. The two ends of the lead screw are respectively fixedly connected to the inner rings of the two bearings.

[0013] As a preferred technical solution of the conveyor belt deviation rectification tooling, the cross-sectional shape of the fixed frame is a "C" shape.

[0014] As a preferred technical solution of the conveyor belt deviation rectification tooling, the first induction switch and the second induction switch are respectively placed on the two side plates.

[0015] As a preferred technical solution of the conveyor belt deviation rectification tooling, the connecting member includes a connecting disc and a locking member. One end of the connecting disc is locked with the moving block through the locking member. The other end of the connecting disc has a mounting hole. The belt roller is placed in the mounting hole.

[0016] As a preferred technical solution of the conveyor belt deviation rectification tooling, the moving block includes a receiving groove. One end of the connecting disc connected to the moving block has a mounting portion. The mounting portion is placed in the receiving groove. The locking member is used to lock the mounting portion in the receiving groove.

[0017] As a preferred technical solution of the conveyor belt deviation rectification tooling, the locking member includes a bolt and a nut. The bolt passes through the receiving groove and the mounting portion. The nut is locked with the bolt.

[0018] As a preferred technical solution of the conveyor belt deviation rectification tooling, the lead screw includes a driving lead screw, a coupling and a driven lead screw.

[0022] The conveyor belt correction fixture provided by this utility model has a first inductive switch and a second inductive switch respectively set on both sides of the conveyor belt along its width direction. It can detect the direction of the conveyor belt deviation when the belt is running. When the conveyor belt deviates towards the direction of the first inductive switch, the first inductive switch sends an electrical signal to the drive component to make the lead screw rotate forward. Under the constraint of the connecting component and the belt roller, the moving block drives the belt roller connected to it to move towards the other belt roller. When the conveyor belt deviates towards the direction of the second inductive switch, the second inductive switch sends an electrical signal to the drive component to make the lead screw rotate backward. Under the constraint of the connecting component and the belt roller, the moving block drives the belt roller connected to it to move away from the other belt roller. This realizes automatic correction of the conveyor belt, avoids the problem of material falling off the conveyor belt due to belt deviation, effectively reduces material loss, and does not require manual monitoring, thus achieving a high degree of automation.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] like Figures 1 to 3 As shown in the figure, this embodiment provides a conveyor belt correction fixture for correcting the deviation of the conveyor belt 101 in the belt conveyor, so as to avoid the problem of the conveyor belt 101 running off-center during the operation of the belt conveyor, reduce the risk of material falling during the material conveying process of the belt conveyor, and reduce material loss.

[0037] The conveyor belt alignment fixture includes a drive unit 1, a lead screw 2, a moving block 3, a connector 4, a first inductive switch 5, and a second inductive switch 6. The output end of the drive unit 1 is connected to the lead screw 2, which is parallel to the length direction of the conveyor belt 101. The moving block 3 is threadedly connected to the lead screw 2. The connector 4 connects the moving block 3 to one of the belt rollers 102 in the conveyor belt. When the drive unit 1 rotates, causing the lead screw 2 to rotate, the moving block 3 moves along the lead screw 2 under the constraint of the connector 4 and the belt roller 102. That is, the moving block 3 moves along the length direction of the conveyor belt 101, which in turn causes the connector 4 to drive the belt roller 102 to swing slightly along the length direction of the conveyor belt 101. Different rotation directions of the lead screw 2 result in different movement directions of the moving block 3, and consequently, different swing directions of the belt roller 102.

[0038] The first sensor switch 5 and the second sensor switch 6 are located on opposite sides of the conveyor belt 101 along its width in the belt conveyor, and both emit laser beams toward the sides of the conveyor belt 101, thus enabling the detection of the distance between the first sensor switch 5 and the second sensor switch 6 and the sides of the conveyor belt 101. Both the first sensor switch 5 and the second sensor switch 6 are electrically connected to the drive unit 1; the first sensor switch 5 controls the drive unit 1 to rotate forward, and the second sensor switch 6 controls the drive unit 1 to rotate in reverse. Both the first sensor switch 5 and the second sensor switch 6 store standard distances. When the first sensor switch 5 or the second sensor switch 6 detects that the distance between itself and the side of the conveyor belt 101 is equal to the standard distance, the conveyor belt 101 does not deviate. When the distance detected by the first sensor switch 5 is less than the standard distance, the conveyor belt 101 deviates towards the first sensor switch 5. The first sensor switch 5 sends an electrical signal to the drive unit 1, and the drive unit 1 rotates forward. Under the constraint of the connecting member 4 and the belt roller 102, the moving block 3 moves forward along the lead screw 2, causing the belt roller 102 connected to the moving block 3 to swing slightly towards the other belt roller 102, so that the conveyor belt 101 returns to the correct position. When the distance detected by the second sensor switch 6 is less than the standard distance, the conveyor belt 101 shifts towards the direction of the second sensor switch 6. The second sensor switch 6 sends an electrical signal to the drive unit 1, causing the drive unit 1 to reverse. Under the constraint of the connector 4 and the belt roller 102, the moving block 3 moves along the direction of the lead screw 2, causing the belt roller 102 connected to the moving block 3 to swing slightly away from the other belt roller 102, so that the conveyor belt 101 returns to the correct position.

[0039] The belt deviation correction tooling provided in this embodiment respectively arranges the first induction switch 5 and the second induction switch 6 on both sides of the conveyor belt 101 along the width direction, and can detect the deviation direction of the conveyor belt 101 when the belt conveyor is running. When the conveyor belt 101 deviates towards the first induction switch 5, the first induction switch 5 sends an electrical signal to the driving member 1 to make the lead screw 2 rotate forward. Under the restriction of the connecting member 4 and the belt roller 102, the moving block 3 drives the belt roller 102 connected thereto to move towards the direction close to the other belt roller 102. When the conveyor belt 101 deviates towards the second induction switch 6, the second induction switch 6 sends an electrical signal to the driving member 1 to make the lead screw 2 rotate reversely. Under the restriction of the connecting member 4 and the belt roller 102, the moving block 3 drives the belt roller 102 connected thereto to move away from the other belt roller 102, realizing automatic deviation correction of the conveyor belt 101, avoiding the problem that the materials above it fall due to the deviation of the conveyor belt 101, effectively reducing material loss, and at the same time, there is no need for manual monitoring, and the automation degree is high.

[0040] Both the first induction switch 5 and the second induction switch 6 can be placed on the support frame, so that the laser emitted by the first induction switch 5 and the second induction switch 6 can shoot to the side surface of the conveyor belt 101.

[0041] In this embodiment, the belt deviation correction tooling further includes a fixed frame 7. Side plates 104 are respectively arranged on both sides of the conveyor belt 101 along the width direction. The fixed frame 7 is connected to the side plates 104. The fixed frame 7 is provided with an opening 71. The driving member 1 is connected to the side wall of the opening 71. The lead screw 2 is placed in the opening 71. Through holes 72 are respectively arranged on two opposite side walls of the opening 71. The two through holes 72 are arranged oppositely, and bearings 73 are arranged in both of the two through holes 72. The two ends of the lead screw 2 are respectively fixed to the inner rings of the two bearings 73. In this way, the rotation of the lead screw 2 can be made more stable, the process of the moving block 3 moving along the lead screw 2 is relatively stable, and further the swing of the belt roller 102 is more stable. Among them, the cross-sectional shape of the fixed frame 7 is in a "C" shape, which is convenient for processing the fixed frame 7. Of course, the cross-sectional shape of the fixed frame 7 can also be a "U" shape, and no specific limitation is made here. Further, the first induction switch 5 and the second induction switch 6 are respectively placed on the two side plates 104, which makes the installation positions of the first induction switch 5 and the second induction switch 6 more reasonable compared with placing the first induction switch 5 and the second induction switch 6 on both sides of the belt conveyor through the support frame respectively.

[0042] For example, the connector 4 includes a connecting plate 41 and a locking member 42. One end of the connecting plate 41 is connected to the moving block 3 via the locking member 42, and the other end of the connecting plate 41 is provided with a mounting hole 412, in which the belt roller 102 is placed. By adjusting the locking member 42, the connecting plate 41 and the moving block 3 can be selectively fixed. When the connecting plate 41 is disassembled from the moving block 3, the connecting plate 41 can be separated from the belt roller 102 by moving the connecting plate 41. This allows for the replacement and maintenance of the connecting plate 41, improving the rationality of the conveyor belt correction fixture design.

[0043] The movable block 3 includes a receiving groove, and one end of the connecting plate 41 connected to the movable block 3 is located in the mounting part 411. The mounting part 411 is placed in the receiving groove, and the locking member 42 is used to lock the mounting part 411 in the receiving groove. By providing the receiving groove and the mounting part 411, the installation of the movable block 3 and the connecting plate 41 is made easier, allowing workers to quickly complete the installation of the movable block 3 and the connecting plate 41.

[0044] For example, the locking element 42 includes a bolt and a nut. The bolt passes through the receiving groove and the mounting portion 411, and the nut locks with the bolt to fix the connecting plate 41 to the movable block 3. By tightening the nut, the connecting plate 41 and the movable block 3 can be disassembled and locked.

[0045] In this embodiment, the lead screw 2 includes a driving lead screw, a coupling, and a driven lead screw. One end of the driving lead screw is connected to the driving component 1, and the other end is connected to the driven lead screw via the coupling. This not only improves the service life of the lead screw 2, but also increases the response speed of the moving block 3 when the driving component 1 drives the lead screw 2 to rotate. This allows for rapid adjustment of the belt roller 102 to correct the conveyor belt 101 after it deviates from its designated path, reducing material loss.

[0046] In this embodiment, the driving component 1 is a servo motor.

[0047] This embodiment provides a belt conveyor, including the aforementioned conveyor belt correction fixture. The belt conveyor also includes a drive motor 103, two belt rollers 102, a conveyor belt 101, and a support (not shown in the figure). The two belt rollers 102 are spaced apart on the support, and the conveyor belt 101 is driven by the two belt rollers 102. The drive motor 103 is connected to one of the belt rollers 102. The conveyor belt correction fixture can adjust one of the belt rollers 102 to correct the deviation of the conveyor belt 101. Thus, when the conveyor belt 101 deviates from its designated path while conveying material, the conveyor belt correction fixture can adjust one of the belt rollers 102 to correct the deviation of the conveyor belt 101, bringing it back to the correct position and preventing material from falling off the conveyor belt 101, effectively reducing material loss.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
