Description

Technical Field

[0001] This utility model belongs to the field of conveyor equipment technology, and in particular relates to an anti-deviation mechanism for conveyor belts. Background Technology

[0002] A conveyor belt is a mechanical component that uses friction as a driving medium to transport materials continuously. It can form a material conveying process on a certain conveying line, from the initial feeding point to the final unloading point.

[0003] Traditional conveyor belts typically have a correction structure at the drive rollers at the ends, using screws to adjust the angle of the drive rollers to achieve the correction effect. However, this method requires staff to check regularly and manually adjust the position of the drive rollers, which not only makes it difficult to ensure the stable conveyor belt in real time, but also increases labor costs due to the need for staff to check regularly. Utility Model Content

[0004] The purpose of this invention is to provide an anti-deviation mechanism for conveyor belts. Specifically, when an electric push rod is activated, it drives the connecting block to move. The push shaft then slides within a straight groove on the support, pushing or pulling the support. This causes the support to rotate, which in turn drives the correction roller to rotate, thus adjusting the angle of the correction roller and correcting the conveyor belt's deviation. This method enables real-time monitoring and adjustment of the conveyor belt, eliminating the need for frequent checks by personnel and reducing labor costs. It also solves the problem of traditional conveyor belts typically using a correction structure at the end of the drive roller. This correction structure usually uses a screw to push the end of the drive roller, causing it to deviate and achieve the correction effect. However, this method requires regular checks and manual adjustment of the drive roller's position, which not only makes it difficult to ensure stable conveyor belt transport in real time but also increases labor costs due to the need for regular checks.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an anti-deviation mechanism for conveyor belts, comprising a conveyor base, wherein a conveyor belt is disposed inside the conveyor base, and a base is fixedly connected to the bottom of the conveyor base, and further comprising:

[0007] The correction mechanism is located inside the base. It includes a rotating seat at the center of the bottom of the conveyor seat, a correction roller rotatably connected to the top of the rotating seat, a photoelectric correction sensor fixedly connected to the front inner side of the conveyor seat, an electric push rod fixedly connected to the bottom inner side of the base, a bracket fixedly connected to the bottom of the rotating seat, a straight groove opened inside the bracket, a connecting block fixedly connected to the output end of the electric push rod, a push shaft fixedly connected to the bottom of the connecting block, and a fixed shaft fixedly connected to the center of the bottom of the rotating seat. A limit post is rotatably connected to the outside of the fixed shaft via a bearing.

[0008] The rotating seat rotates around the limiting column via a fixed shaft, and the outer surface of the correction roller contacts the conveyor belt.

[0009] Furthermore, the bracket has an L-shaped structure, with a gap between the bottom of the bracket and the base. The push shaft is slidably connected inside the straight groove, and a gap is left between the bottom of the connecting block and the bracket. The bottom of the limiting post is fixedly connected to the inner bottom of the base. The limiting post cooperates with the fixed shaft to support and limit the rotating seat. Since the push shaft slides inside the straight groove, the bracket can be pushed smoothly. Since the bottom of the rotating seat rotates on the limiting post through the fixed shaft, the rotating seat will drive the correction roller to move in a rotating manner, thereby adjusting the angle of the correction roller.

[0010] Furthermore, a tension adjustment mechanism is provided on the outer side of the rotating seat. The tension adjustment mechanism includes two lifting seats located on the left and right sides of the rotating seat. Tension rollers are rotatably connected to the lifting seats, and tension detectors are installed at the ends of the tension rollers. Two slide rods are fixedly connected to the bottom of each of the two lifting seats, and a base plate is fixedly connected to the bottom of the four slide rods. An electric push rod is fixedly connected to the bottom of the base. When the base plate is raised or lowered, it will drive the two lifting seats to move simultaneously through the four slide rods.

[0011] Furthermore, the bottom output end of the electric push rod two is fixedly connected to the top of the base plate via a flange. The slide rod slides through the base and extends to the outside. The slide rod is used to limit the lifting seat. The outer surface of the tension roller contacts the inner side of the conveyor belt. The two tension rollers cooperate with the correction roller to adjust the tension of the conveyor belt. The photoelectric correction sensor is set above the correction roller. The correction roller and the two tension rollers are arranged in a triangle. The correction roller and the two tension rollers cooperate with each other to make the tension roller smoothly adjust the tension of the conveyor belt. Moreover, by adjusting the tension, the adjustment of the correction roller can be more precise.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model sets up a correction mechanism. Specifically, when the electric push rod is started, it drives the connecting block to move. The push shaft will slide in the straight groove on the bracket, thereby pushing or pulling the bracket. At this time, the bracket will drive the rotating seat to rotate together. The rotating seat will drive the correction roller to rotate, thereby adjusting the angle of the correction roller and correcting the conveyor belt. This method can make the conveyor belt monitored and adjusted in real time, eliminating the need for frequent inspections by staff and reducing labor costs.

[0014] 2. This utility model, by setting a tension adjustment mechanism, specifically, when the electric push rod is activated, it drives the base plate to move up or down. The base plate will then drive the four sliding rods to move together. At this time, the two lifting seats will drive the two tension rollers to rise and fall together, thereby adjusting the tension of the conveyor belt to the set range. This not only ensures the stable conveying of materials, but also improves the correction effect of the correction rollers.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0025] See Figures 1-5 As shown, this utility model is an anti-deviation mechanism for a conveyor belt, including a conveyor seat 1, a conveyor belt 11 disposed inside the conveyor seat 1, a base 12 fixedly connected to the bottom of the conveyor seat 1, and further including:

[0026] The correction mechanism 2 is located inside the base 12. The correction mechanism 2 includes a rotating seat 21 located at the center of the bottom of the conveyor seat 1. A correction roller 22 is rotatably connected to the top of the rotating seat 21. A photoelectric correction sensor 23 is fixedly connected to the front inner side of the conveyor seat 1. An electric push rod 121 is fixedly connected to the bottom inner side of the base 12. A bracket 24 is fixedly connected to the bottom of the rotating seat 21. A straight groove 241 is opened inside the bracket 24. A connecting block 25 is fixedly connected to the output end of the electric push rod 121. A push shaft 251 is fixedly connected to the bottom of the connecting block 25. A fixed shaft 211 is fixedly connected to the center of the bottom of the rotating seat 21. A bearing passes through the outer side of the fixed shaft 211. The rotatable connection is limited by the post 212; when the electric push rod 121 is started, it drives the connecting block 25 to move, and the push shaft 251 will slide in the straight groove 241 on the bracket 24, thereby pushing or pulling the bracket 24. At this time, the bracket 24 will drive the rotating seat 21 to rotate together, and the rotating seat 21 will drive the correction roller 22 to rotate, thereby adjusting the angle of the correction roller 22 and correcting the conveyor belt 11. This method allows the conveyor belt 11 to be monitored and adjusted in real time, without the need for frequent inspection by staff, reducing labor costs; the rotating seat 21 rotates around the post 212 via the fixed shaft 211, and the outer surface of the correction roller 22 contacts the conveyor belt 11.

[0027] The bracket 24 is L-shaped, with a gap between the bottom of the bracket 24 and the base 12. The push shaft 251 is slidably connected inside the straight groove 241. There is a gap between the bottom of the connecting block 25 and the bracket 24. The bottom of the limiting post 212 is fixedly connected to the bottom of the inner side of the base 12. The limiting post 212 and the fixed shaft 211 cooperate to support and limit the rotating seat 21.

[0028] A tension adjustment mechanism 3 is provided on the outer side of the rotating seat 21. The tension adjustment mechanism 3 includes two lifting seats 31 located on the left and right sides of the rotating seat 21. Tension rollers 32 are rotatably connected to the lifting seats 31. Tension detectors 33 are installed at the ends of the tension rollers 32. Two slide rods 34 are fixedly connected to the bottom of each of the two lifting seats 31. A base plate 35 is fixedly connected to the bottom of the four slide rods 34. An electric push rod 36 is fixedly connected to the bottom of the base 12. When the electric push rod 36 is activated, it drives the base plate 35 to move up or down. The base plate 35 will then drive the four slide rods 34 to move together. At this time, the two lifting seats 31 will drive the two tension rollers 32 to rise and fall together, thereby adjusting the tension of the conveyor belt 11 to the set range. This not only ensures the stable conveying of materials, but also improves the correction effect of the correction roller 22.

[0029] The bottom output end of the electric push rod 36 is fixedly connected to the top of the base plate 35 via a flange. The slide rod 34 slides through the base 12 and extends to the outside. The slide rod 34 is used to limit the lifting seat 31. The outer surface of the tension roller 32 contacts the inner side of the conveyor belt 11. The two tension rollers 32 cooperate with the correction roller 22 to adjust the tension of the conveyor belt 11. The photoelectric correction sensor 23 is set above the correction roller 22. The correction roller 22 and the two tension rollers 32 are arranged in a triangle.

[0030] One specific application of this embodiment is:

[0031] When the conveyor belt 11 is conveying materials, the photoelectric correction sensor 23 monitors the position of the conveyor belt 11 in real time and feeds back to the controller. When the conveyor belt 11 needs to be corrected, the controller controls the electric push rod 121 to start and drive the connecting block 25 to move. The push shaft 251 will slide in the straight groove 241 on the bracket 24, thereby pushing or pulling the bracket 24. At this time, the bracket 24 will drive the rotating seat 21 to rotate together. Since the bottom of the rotating seat 21 rotates on the limit post 212 through the fixed shaft 211, the rotating seat 21 will drive the correction roller 22 to rotate, thereby adjusting the angle of the correction roller 22 and correcting the conveyor belt 11. The correction roller 22 and the two tension rollers 32 can smoothly adjust the conveyor belt 11. This method can make the conveyor belt 11 monitored and adjusted in real time, without the need for frequent inspection by the staff, reducing labor costs. The photoelectric correction sensor 23 is model PS-400S.

[0032] Meanwhile, the tension detector 33 on the lifting seat 31 will detect the tension of the conveyor belt 11. The tension detector 33 is a UNITTA U-507 / U-508. The detected tension is then fed back to the controller. When the tension needs to be adjusted, the controller controls the electric push rod 36 to start. The electric push rod 36 drives the base plate 35 to move up or down. The base plate 35 will drive the four slide rods 34 to move together. At this time, the two lifting seats 31 will drive the two tension rollers 32 to rise and fall together, thereby adjusting the tension of the conveyor belt 11 to the set range. This not only ensures the stable conveying of materials, but also improves the correction effect of the correction roller 22.

[0033] It should be noted that the control of the electric push rod 121, the photoelectric correction sensor 23, the tension detector 33 and the electric push rod 36 in this application are all achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.
