A self-aligning and track-correcting conveyor structure for belt conveyors

Abstract

This utility model discloses a self-aligning and corrective conveying structure for a belt conveyor, including a base and a conveyor belt for conveying materials, which is disposed above the base. A positioning seat is centrally disposed in the mounting groove above the base, and a correction mechanism for adjusting the center of gravity of the conveyor belt is disposed between the positioning seat and the inner wall of the base. This utility model has a simple structure and reasonable design. When the center of gravity of the material on the conveyor belt shifts due to uneven distribution, the correction roller drives the conveyor belt to vibrate on one side to correct the position of the material and adjust the center of gravity. This makes the wear on both sides of the belt relatively uniform, improves the service life of the belt, and reduces the risk of the conveyor system tipping over. At the same time, when the tilt critical point is reached, the correction roller is triggered by a touch switch to correct the tilt. After the tilt is restored, the vibration of the correction roller stops synchronously when the touch switch is separated, resulting in good synchronization.

Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor equipment, specifically to a belt conveyor self-aligning and correction conveying structure. Background Technology

[0002] Belt conveyors, as one of the most important continuous conveying devices in modern industrial production, are widely used in material handling systems across various industries such as mining, metallurgy, chemical, power, and building materials. They offer advantages such as long conveying distances, large carrying capacities, and continuous conveying, making them particularly suitable for transporting bulk materials such as coal, ore, and grain. With the continuous improvement of industrial automation, the requirements for the operational stability and reliability of belt conveyors are also increasing.

[0003] The shortcomings of existing technology:

[0004] Currently, belt conveyors still have significant drawbacks in practical use. Because materials are usually randomly distributed on the conveyor belt, it is difficult to ensure uniform load, which can easily cause the center of gravity of the conveying system to shift during the conveying process. This shift in the center of gravity will first cause uneven stress on one side of the belt, accelerating belt wear and shortening its service life. Secondly, if the material is heavy, a significant shift in the center of gravity may also pose a risk of the conveying system tipping to one side. Utility Model Content

[0005] The purpose of this invention is to provide a self-aligning and corrective conveying structure for belt conveyors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a belt conveyor self-aligning and correction conveying structure, including a base and a conveyor belt disposed above the base for conveying materials, a positioning seat disposed centrally in the mounting groove above the base, and a correction mechanism for adjusting the center of gravity of the conveyor belt disposed between the positioning seat and the inner wall of the base.

[0007] The correction mechanism includes:

[0008] The correction rollers are symmetrically arranged on both sides of the positioning seat, and the ends of the roller shafts of the correction rollers are movably connected to the seat body of the positioning seat.

[0009] The lifting seat is slidably connected in the vertical grooves on both sides of the base, and the roller shaft of the correction roller away from the positioning seat is rotatably connected to the lifting seat.

[0010] A vibration mechanism is disposed in the cavity on both sides of the inner wall of the base and located below the lifting seat. The vibration mechanism is used to drive the lifting seat to move up and down.

[0011] A triggering component is disposed between the inner walls of the base on the side of the straightening roller facing the material.

[0012] Preferably, the triggering component includes:

[0013] A bracket is centrally located in a mounting slot above the base. A rotating seat is rotatably connected to the bracket, and an induction roller is rotatably connected to the upper end of the rotating seat through a horizontal slot.

[0014] Card holders are symmetrically arranged on the inner wall of the base, and touch switches are provided at the ends of the card holders, which are located below the two ends of the sensing roller.

[0015] Preferably, the vibration mechanism includes:

[0016] Two eccentric discs are respectively disposed in the cavities of the inner walls on both sides of the base. The two eccentric discs are symmetrically disposed below the lifting seat. A first connecting rod is symmetrically disposed on the lower end surface of the lifting seat. The lower end of the first connecting rod is rotatably connected to a second connecting rod. The lower end of the second connecting rod is rotatably connected to the rotating shaft on the two eccentric discs.

[0017] The motor is installed in the mounting slot of the base, and the output end of the motor is connected to the shaft of either of the two eccentric discs. The shafts of the two eccentric discs are also connected to a synchronous belt.

[0018] Preferably, the number of the correction mechanism is 2-3 groups, and the number of correction rollers in each group of the correction mechanism is 4.

[0020] Preferably, the roller shaft on the side of the straightening roller furthest from the ball head is a telescopic shaft.

[0021] Preferably, the touch switch is movably mounted in a telescopic groove at the end of the card holder via a spring.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This belt conveyor self-aligning and correction conveying structure, by setting up a correction mechanism, realizes that when the center of gravity of the material on the conveyor belt shifts due to uneven distribution, the correction roller drives the conveyor belt to vibrate on one side to correct the position of the material and adjust the center of gravity. This makes the wear on both sides of the belt relatively uniform, improves the service life of the belt, and reduces the risk of the conveyor system tipping over.

[0024] This belt conveyor self-aligning and correction conveying structure, by setting a trigger component and using an induction roller, realizes real-time feedback on the tilt of the conveyor belt. When the tilt critical point is reached, it can contact a touch switch to trigger the correction roller behind it to correct the tilt. After the tilt is restored, the induction roller separates from the touch switch and the vibration of the correction roller behind it stops synchronously. The response is rapid and timely, and the synchronization is good. Attached Figure Description

[0038] Please see Figure 1-8 As shown, this utility model provides a self-aligning and correcting conveyor structure for a belt conveyor: A self-aligning and correcting conveyor structure for a belt conveyor includes a base 1 and a conveyor belt 2 installed above the base 1 for conveying materials. The conveyor belt 2 is powered by an external power system, driving the materials above it to move horizontally. A positioning seat 3 is centrally fixedly installed in the mounting groove above the base 1, and a correction mechanism 4 for adjusting the center of gravity of the conveyor belt 2 is provided between the positioning seat 3 and the inner wall of the base 1.

[0039] The correction mechanism 4 includes correction rollers 401, lifting seats 402, vibration mechanisms 403, and triggering components 5. The correction rollers 401 are symmetrically arranged on both sides of the positioning seat 3, and the ends of the roller shafts of the correction rollers 401 are movably connected to the seat body of the positioning seat 3. Each set of correction mechanisms 4 contains four correction rollers 401, with two correction rollers 401 on each side of the positioning seat 3. The lifting seats 402 are slidably connected to the vertical grooves on the inner walls of both sides of the base 1, such as... Figure 6As shown, sliding strips are provided on both sides of the lifting seat 402. The vertical grooves on the inner walls of both sides of the base 1 are further opened to slide and connect with the sliding strips on both sides of the lifting seat 402, further ensuring the lifting trajectory of the lifting seat 402. The roller shaft of the correction roller 401 away from the positioning seat 3 is rotatably connected to the lifting seat 402. The vibration mechanism 403 is installed in the cavity of the inner wall on both sides of the base 1, located below the lifting seat 402. The vibration mechanism 403 is used to drive the lifting seat 402 to move up and down. The trigger assembly 5 is installed between the inner walls of the base 1, located on the side of the correction roller 401 facing the material.

[0040] When the conveyor belt 2 tilts to one side, the triggering component 5 is triggered, and the external controller controls the vibration mechanism 403 on that side to start. The lifting seat 402 on that side then begins to drive one side of the correction roller 401 to vibrate up and down at high frequency. The other end of the correction roller 401 is connected to the positioning seat 3 by rotating relative to it. Figure 8 As shown, when the lifting seat 402 moves to the upper end, one side of the correction roller 401 contacts and impacts one side of the conveyor belt 2, causing the material on that side of the conveyor belt 2 to vibrate and move towards the middle of the transmission belt 2, thereby adjusting the overall center of gravity of the conveyor belt 2.

[0041] By using the correction mechanism 4, when the center of gravity of the material on the conveyor belt 2 shifts due to uneven distribution, the correction roller 401 drives the conveyor belt 2 to vibrate on one side to correct the position of the material and adjust the center of gravity. This makes the wear on both sides of the belt relatively uniform, improves the service life of the belt, and reduces the risk of the conveyor system tipping over.

[0042] The trigger assembly 5 includes a bracket 501 and a mounting base 504. The bracket 501 is centrally and fixedly installed in a mounting groove above the base 1. A rotating seat 502 is rotatably connected to the bracket 501, and a sensing roller 503 is rotatably connected to the upper end of the rotating seat 502 via a transverse groove. The mounting directions of the bracket 501, rotating seat 502, and sensing roller 503 are as follows: Figure 4 and Figure 5 As shown. The card holder 504 is symmetrically fixedly installed on the inner wall of the base 1. A touch switch 505 is movably installed at the end of the card holder 504. The touch switch 505 is located below both ends of the sensing roller 503.

[0043] During transport, conveyor belt 2 passes over the front sensing roller 503 before contacting the correction roller 401. When conveyor belt 2 tilts to one side and passes the sensing roller 503, it causes the sensing roller 503 to tilt synchronously. After the lowest point of the tilted sensing roller 503 contacts the touch switch 505, the external controller receives the electrical signal from the touch switch 505 and can then activate the corresponding vibration mechanism 403 at the rear end to drive the correction roller 401 to vibrate up and down. After the end of the sensing roller 503 separates from the touch switch 505, the external controller can then control the vibration mechanism 403 to shut down. The external control system activates the vibration mechanism 403 behind the corresponding touch switch 505 through a preset program.

[0044] By using the trigger component 5 and the sensing roller 503, real-time feedback on the tilt of the conveyor belt 2 is achieved. When the tilt critical point is reached, the sensing roller 503 can contact the touch switch 505 to trigger the correction roller 401 behind it to correct the tilt. After the tilt is restored, the sensing roller 503 separates from the touch switch 505 and the vibration of the correction roller 401 behind it stops synchronously. The response is rapid and timely and the synchronization is good.

[0045] The vibration mechanism 403 includes two eccentric discs 4031 and a motor 4034. The two eccentric discs 4031 are respectively installed in the cavities on the inner walls of both sides of the base 1. The two eccentric discs 4031 are symmetrically installed below the lifting seat 402. A first connecting rod 4032 is symmetrically installed on the lower end surface of the lifting seat 402. The lower end of the first connecting rod 4032 is rotatably connected to a second connecting rod 4033. The lower end of the second connecting rod 4033 is rotatably connected to the rotating shafts on the two eccentric discs 4031. The motor 4034 is fixedly installed in the mounting slot of the base 1 by a bracket, and the output end of the motor 4034 is connected to the shaft of any one of the two eccentric discs 4031. A synchronous belt 4035 is also connected to the shafts of the two eccentric discs 4031.

[0046] When the vibration mechanism 403 is running, the motor 4034 starts and drives the two eccentric discs 4031 to rotate synchronously through the synchronous belt 4035. During the rotation of the two eccentric discs 4031, the first connecting rod 4032 is driven to move up and down through the second connecting rod 4033, thereby driving the lifting seat 402 to vibrate up and down. The higher the speed of the motor 4034, the more obvious the vibration effect.

[0047] There are 2-3 sets of correction mechanisms 4. If the first set of correction mechanisms 4 does not complete the correction, the subsequent correction mechanisms 4 can continue to perform correction operations to ensure the correction effect.

[0048] A ball head 4011 is provided on one end of the straightening roller 401. The two sides of the positioning seat 3 are movably connected to the ball head 4011 by opening ball grooves. Balls are also installed in the ball grooves on both sides of the positioning seat 3. The ball head 4011 and the ball groove have good mobility, which can ensure the rotation of the straightening roller 401 and also meet the mobility when one end of the straightening roller 401 vibrates. The ball also effectively reduces the friction between the two.

[0049] The side of the correction roller 401 furthest from the ball head 4011 is a telescopic shaft. When the vibration mechanism 403 drives the correction roller 401 to vibrate, the telescopic nature of one end can avoid interference and ensure the motion effect.

[0050] The touch switch 505 is movably mounted in the telescopic groove at the end of the card holder 504 by a spring. After the sensing roller 503 triggers the touch switch 505, the touch switch 505 will retract into the telescopic groove to avoid damage.

[0051] The working principle of this utility model is as follows:

[0052] During transport, conveyor belt 2 first passes over the front sensing roller 503. When conveyor belt 2 tilts to one side, it causes sensing roller 503 to tilt synchronously as it passes over it. After the lowest point of the tilted sensing roller 503 contacts the touch switch 505, the external controller receives the electrical signal from the touch switch 505 and can then activate the corresponding rear motor 4034. Motor 4034 drives the lifting seat 402 and the correction roller 401 to vibrate up and down. One side of the correction roller 401 contacts the tilted side of conveyor belt 2, causing the material on that side of conveyor belt 2 to vibrate and move towards the center of the conveyor belt 2, thereby adjusting the overall center of gravity of conveyor belt 2. After the end of sensing roller 503 separates from touch switch 505, the external controller can then control motor 4034 to shut down.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
