Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a belt conveyor device with anti-deviation function. Background Technology

[0002] Belt conveyors, also known as belt conveyors or rubber belt conveyors, are friction-driven conveying systems for transporting loose materials or packaged goods. They mainly consist of a frame, conveyor belt, belt rollers, tensioning device, and transmission device, and offer advantages such as large conveying capacity, simple structure, convenient maintenance, and standardized components. Belt conveyors are widely used in mining, metallurgy, and coal industries to transport easily extractable, low-abrasive materials such as coal, gravel, sand, cement, fertilizer, and grain, with a bulk density of less than 1.67 tonnes per cubic meter.

[0003] The working principle of a belt conveyor is based on the principle of frictional transmission. When the motor drives the drive drum to rotate, the frictional force drives the conveyor belt to rotate, thereby achieving continuous material transport. Material enters the conveyor belt through the feed inlet, moves along with the conveyor belt under the action of friction, and is finally discharged from the outlet. During the conveying process, the frictional forces between the material and the conveyor belt, as well as the mutual frictional forces among the materials, enable the material to run stably on the conveyor belt, thus achieving continuous transport.

[0004] During the conveying of finished products, items are prone to deviation due to inaccurate initial placement or various factors during transport (such as belt swaying or irregular shapes). This not only affects the normal conveying of items but also easily causes them to fall off the conveyor belt, damaging them or impacting subsequent production processes, thus reducing production efficiency. Therefore, a belt conveyor device with anti-deviation function is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a belt conveyor device with anti-deviation function, which aims to improve the problem in the prior art that the objects are prone to deviation due to inaccurate initial placement or various factors during transportation, resulting in a decrease in production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A belt conveyor device with anti-deviation function includes a base, a belt conveyor fixedly connected to the top of the base, a positioning and placement mechanism provided on the front side of the base, and a guide mechanism provided on the top of the belt conveyor.

[0008] The positioning and placement mechanism includes a long strip block. The bottom end of the long strip block is fixedly connected to the top front side of the belt conveyor. A motor is fixedly connected to the inner bottom wall of the long strip block. A gear is fixedly connected to the drive end of the motor. Two guide grooves are formed on the inner bottom wall of the long strip block. Sliding plates are slidably connected to the inner walls of the guide grooves. A rack plate is fixedly connected to the adjacent side of the two sliding plates. A connecting plate is fixedly connected to the distant side of the two rack plates. A U-shaped rod is fixedly connected to the distant side of the two connecting plates. A positioning plate is fixedly connected to the adjacent top side of the two U-shaped rods.

[0009] As a further description of the above technical solution:

[0010] The guiding mechanism includes multiple square blocks, which are externally fixedly connected to the top of the belt conveyor. Cylinders are fixedly connected to the inner walls of the opposite sides of two square blocks. A transmission plate is fixedly connected to the driving end of the cylinder. Multiple transmission rods are fixedly connected to the adjacent sides of the two transmission plates. A fixed plate is fixedly connected to the side of the transmission rod closest to the belt conveyor. A sliding frame is slidably connected inside the fixed plate. A support seat is fixedly connected to the side of the sliding frame closest to the belt conveyor. A guide wheel is rotatably connected to the inner wall of the support seat.

[0011] As a further description of the above technical solution:

[0012] The outer sides of the two rack plates are meshed with the outer side of the gear, and the bottom sides of the two rack plates are slidably connected to the bottom inner wall of the long strip block;

[0013] As a further description of the above technical solution:

[0014] A square plate is fixedly connected to the outside of the U-shaped rod, and the bottom sides of the two square plates are slidably connected to the top side of the long strip.

[0015] As a further description of the above technical solution:

[0016] The top left and right sides of the long strip are provided with movable holes, and the outer wall of the U-shaped rod is slidably connected to the inner wall of the movable holes;

[0017] As a further description of the above technical solution:

[0018] The bottom sides of the two connecting plates are slidably connected to the bottom inner wall of the long strip block, and the bottom sides of the two positioning plates are in contact with the top side of the long strip block;

[0019] As a further description of the above technical solution:

[0020] The outer wall of the transmission plate is slidably connected to the inner wall of the square block, and the outer walls of the plurality of transmission rods are slidably connected to the inner wall of the square block;

[0021] As a further description of the above technical solution:

[0022] Two springs are fitted on the outside of the sliding frame. The two springs are fixedly connected to the outer wall of the support base on the side closer to the belt conveyor, and the two springs are fixedly connected to the outer wall of the fixed plate on the side away from the belt conveyor.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, after the motor in the positioning and placement mechanism is started, it drives the gear to rotate. The gear meshes with the rack plate, causing the rack plate to move. This, in turn, drives the U-shaped rod to move left and right through the connecting plate. The U-shaped rod causes the positioning plate to move closer to or further away from the object. When the object begins to be transported, the positioning plate can center the object, preventing it from deviating due to inaccurate initial placement. For objects of different widths, the positioning plate can achieve centering by moving in opposite directions, increasing the applicability of the device.

[0025] 2. In this invention, when an object deviates from its designated path during transport on the belt conveyor, it will contact the guide wheel of the guiding mechanism. With the assistance of the transmission rod, the guide wheel gradually guides the deviated object back to the center of the belt conveyor. Simultaneously, the square block in the guiding mechanism generates power to move the guiding mechanism towards the center of the belt conveyor, thus guiding objects of different widths and preventing further deviation. Furthermore, the spring absorbs energy when the object touches the guide wheel, protecting the object and aiding in the adjustment of the guide wheel's position, ensuring the effective implementation of the anti-deviation function.

Detailed Implementation

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

[0034] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a belt conveyor device with anti-deviation function, comprising a base 1, a belt conveyor 2 fixedly connected to the top of the base 1, a positioning and placement mechanism on the front side of the base 1, and a guiding mechanism on the top of the belt conveyor 2; the base 1 serves as the basic support structure for the entire device. It provides a stable mounting platform for the belt conveyor 2, ensuring that the belt conveyor 2 remains stable during operation and that the conveying of objects is not affected by shaking. Simultaneously, it provides a solid connection foundation for the positioning and placement mechanism and the guiding mechanism, ensuring the coordinated operation of the entire device. The belt conveyor 2 is the main component for object conveying. It transports objects from one end to the other through the cyclic rotation of the belt. In the entire device, it is the carrier of object transportation and the key part for realizing object displacement.

[0035] The positioning and placement mechanism includes a long strip block 3. The bottom end of the long strip block 3 is fixedly connected to the top front side of the belt conveyor 2. A motor 4 is fixedly connected to the inner bottom wall of the long strip block 3, and a gear 5 is fixedly connected to the drive end of the motor 4. The long strip block 3 mainly serves as a connection and support, providing installation space and structural support for components such as the motor 4 and gear 5, and is the support for other components in the positioning and placement mechanism. The motor 4 is the power source of the positioning and placement mechanism. When the motor 4 is turned on, it generates power and transmits it to the gear 5. Two guide grooves are opened on the inner bottom wall of the long strip block 3. Sliding plates 6 are slidably connected to the inner walls of the guide grooves. A rack plate 7 is fixedly connected to the adjacent side of the two sliding plates 6. The outer sides of the two rack plates 7 are meshed with the outer sides of the gear 5. The rotation of the gear 5 can be converted into the linear movement of the rack plate 7. It is a key conversion component that converts the rotational power of the motor 4 into the linear motion power of the positioning plate 12. The guide grooves provide a sliding track for the sliding plates 6. The sliding plate 6 slides within the guide groove, ensuring that the rack plate 7 maintains a stable orientation during movement, thereby accurately achieving meshing motion with the gear 5 and ensuring the accuracy of the entire positioning and placement mechanism. The bottom sides of the two rack plates 7 are slidably connected to the bottom inner wall of the elongated block 3. Connecting plates 8 are fixedly connected to the opposite sides of the two rack plates 7, and the bottom sides of the two connecting plates 8 are slidably connected to the bottom inner wall of the elongated block 3. U-shaped rods 9 are fixedly connected to the opposite sides of the two connecting plates 8. The connecting plates 8 connect the rack plates 7 and the U-shaped rods 9, and transmit the linear motion of the rack plates 7 to the U-shaped rods 9, ensuring that the U-shaped rods 9 can move in the predetermined direction.

[0036] Square plates 10 are fixedly connected to the outside of the U-shaped rod 9, and the bottom sides of the two square plates 10 are slidably connected to the top side of the long strip block 3. The square plates 10 assist the U-shaped rod 9 in sliding on the top of the long strip block 3, making the movement of the U-shaped rod 9 more stable. Movable holes 11 are opened on both the left and right sides of the top of the long strip block 3, and the outer wall of the U-shaped rod 9 is slidably connected to the inner wall of the movable holes 11. The movable holes 11 provide space for the sliding of the U-shaped rod 9, limit the movement trajectory of the U-shaped rod 9, and ensure that the U-shaped rod 9 can only move in a straight line in the left and right direction, thereby ensuring the accurate movement of the positioning plate 12. Positioning plates 12 are fixedly connected to the top of the two U-shaped rods 9 on their adjacent sides. The bottom sides of the two positioning plates 12 are in contact with the top side of the long strip block 3. The positioning plates 12 move closer or further away under the drive of the U-shaped rods 9. Their function is to center the object being conveyed, prevent the object from deviating due to inaccurate initial placement, and center the object for objects of different widths, thus improving the applicability of the device.

[0037] Reference Figure 1 , Figure 4 and Figure 5The guiding mechanism includes multiple square blocks 13, which are externally fixedly connected to the top of the belt conveyor 2. Cylinders 14 are fixedly connected to the inner walls of opposite sides of two square blocks 13. A transmission plate 15 is fixedly connected to the drive end of each cylinder 14. The square blocks 13 provide mounting positions for components such as the cylinders 14 and transmission plates 15. The outer wall of the transmission plate 15 is slidably connected to the inner wall of the square blocks 13. Multiple transmission rods 16 are fixedly connected to the adjacent sides of the two transmission plates 15, and their outer walls are slidably connected to the inner walls of the square blocks 13. A fixing plate 17 is fixedly connected to the side of the transmission rod 16 closest to the belt conveyor 2. A sliding frame 18 is slidably connected inside the fixing plate 17. A support seat 20 is fixedly connected to the side of the sliding frame 18 closest to the belt conveyor 2. A guide wheel 21 is rotatably connected to the inner wall of the support seat 20. As a power component, cylinder 14, when started, drives transmission plate 15 to move, which in turn drives guide wheel 21 to move via transmission rod 16 and other components. It is the power source for adjusting the position of guide wheel 21 in the guiding mechanism. Transmission plate 15 transmits the power of cylinder 14 to transmission rod 16, serving as an intermediate component connecting cylinder 14 and transmission rod 16, ensuring effective power transmission. Transmission rod 16 connects transmission plate 15 and fixed plate 17. Its gradually increasing length, combined with the function of guide wheel 21, gradually guides the object to the center of belt conveyor 2 when it deviates from its path. Simultaneously, it transmits the power of transmission plate 15 to fixed plate 17. Two springs 19 are fitted onto the outside of sliding frame 18. The side of the two springs 19 closest to belt conveyor 2 is fixedly connected to the outer wall of support base 20, and the side of the two springs 19 furthest from belt conveyor 2 is fixedly connected to the outer wall of fixed plate 17. When an object deviates and touches the guide wheel 21, the spring 19 absorbs the energy of the collision, protecting the object and also participating in the adjustment of the guide wheel 21's position. The guide wheel 21 will contact the object when it deviates. Under the action of the transmission rod 16, the deviated object can be gradually guided to the middle position of the belt conveyor 2, preventing the object from continuing to deviate.

[0038] Working principle: The motor 4 inside the long block 3 generates power to drive the gear 5 to rotate. Since the rack plate 7 and the gear 5 are meshed, the rotation of the gear 5 drives the two rack plates 7 to move in opposite or opposite directions. The movement of the rack plates 7, in conjunction with the connection plate 8, drives the U-shaped rod 9 to move left and right. This movement of the U-shaped rod 9 drives the two positioning plates 12 to move closer or further apart, so that the object being conveyed can be centered and positioned, preventing the object from deviating due to inaccurate initial placement. At the same time, the opposite movement of the positioning plates 12 can be used to center objects of different widths, increasing the applicability of the device.

[0039] When an object is transported on the belt conveyor 2, it will touch the guide wheel 21 on the guide mechanism when it deviates from its course. The spring 19 can absorb the energy of the collision and protect the object. At the same time, the length of the transmission rod 16 gradually increases, which, together with the action of the guide wheel 21, can gradually guide the deviated object to the middle position of the belt conveyor 2, thereby preventing the object from deviating. Through the multiple sets of square blocks 13 set on the belt conveyor 2, the power generated by opening the square blocks 13 drives the guide mechanism to move towards the middle of the belt conveyor 2, realizing the guidance of objects of different widths.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
