Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt conveyor technology, and in particular to a belt correction mechanism for a belt conveyor. Background Technology
[0002] A belt conveyor is a mechanical device for continuously transporting materials. Its working principle involves using friction to drive a circular conveyor belt in a cyclical motion, thereby carrying and transporting bulk materials or packaged goods. It features long conveying distances, large capacity, simple structure, and convenient maintenance, and is widely used in industries such as mining, ports, power, and building materials. It is suitable for conveying materials horizontally or at an angle of inclination less than 20°, and its length, width, and material can be customized according to requirements.
[0003] The main roller is an important component of the belt alignment mechanism of a belt conveyor. However, the main roller is usually threaded or fixed, which makes disassembly and installation very inconvenient, thus prolonging downtime for maintenance. In addition, the auxiliary rollers of most alignment mechanisms are fixed and difficult to adjust the angle, resulting in poor adaptability to belts of different widths. This reduces production efficiency and has an adverse effect on belt alignment.
[0004] Therefore, those skilled in the art have provided a belt correction mechanism for a belt conveyor to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of existing technologies by proposing a belt correction mechanism for a belt conveyor. The mechanism positions the chuck, connecting rod, and main roller by engaging them with a fixed base. Pulling the pull rod extends the spring extension rod and lowers the partition plate, causing the chuck plate below it to move to a suitable height and engage with the chuck. Holding the handle and rotating the chuck plate 90 degrees along the slide rail, the worm gear drives the worm wheel, which in turn drives the threaded column to rotate around the rotating part. This causes the slider to move downwards under the limit of the second guide rod, engaging the insertion rod with the chuck plate and chuck, thus completing the installation of the main roller. Disassembly is the reverse process, facilitating the maintenance and replacement of the main roller and improving the practicality of the mechanism.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A belt alignment mechanism for a belt conveyor includes a fixed base, a controller, side bases, hangers, first servo motors, first threaded rods, and sliding frames. Hangers are fixedly connected to both ends of the upper surface of the fixed base. The controller is mounted on the upper part of one side surface of each hanger. Side bases are fixedly connected to both ends of the fixed base. First servo motors are mounted on one end of the upper surface of each of the two side bases. First threaded rods are fixedly connected to the output ends of each of the two first servo motors. Sliding frames are fitted onto the outer walls of each of the two first threaded rods. A convenient disassembly and assembly mechanism is provided at the lower end of each hanger. An adjustment mechanism is provided on the upper surface of each of the two sliding frames. The convenient disassembly and assembly mechanism includes a spring telescopic rod. A partition is fixedly connected to the lower end of the spring telescopic rod. First guide rods are fixedly connected to both ends of the upper surface of the partition. A pull rod is fixedly connected to the middle of one side surface of the partition. Second guide rods are fixedly connected to both ends of the lower surface of the partition. The outer walls of the second guide rods slide on both sides. The system includes a slider with insert rods fixedly connected to both sides of its lower end face. A threaded column is rotatably connected to the middle of the lower end face of the partition. A worm gear is fixedly connected to one end of the outer wall of the threaded column. A worm is meshed with one side of the outer wall of the worm gear. A rotating part is rotatably connected to the lower end of the threaded column. A clamping plate is rotatably connected to the lower end of the rotating part. A clamping groove is provided at both ends of the upper end face of the clamping plate. A handle is fixedly connected to one end of the upper end face of the clamping plate. A chuck is engaged at both ends of the clamping plate. A slide rail is provided on one side of the upper end face of the chuck. A connecting rod is fixedly connected to one side of the outer wall of the chuck. A main roller is rotatably connected to the upper end of the connecting rod. The adjustment mechanism includes two second servo motors. A second threaded rod is fixedly connected to the output end of each of the two second servo motors. A slide block is sleeved on one side of the outer wall of each of the two second threaded rods. An auxiliary roller is rotatably connected to one end of the upper end face of each of the two sliding frames. A pulley is rotatably connected to one end of the lower end face of each of the two auxiliary rollers.
[0008] Through the above technical solution, the mechanism completes positioning by clamping the chuck, connecting rod, and main roller onto the upper end of the fixed base. Then, pulling the pull rod extends the spring telescopic rod and lowers the partition plate. The lowering of the partition plate causes the clamping plate below it to move down to a suitable height and engage with the chuck. Next, gripping the handle and rotating the clamping plate 90 degrees along the slide rail, and finally twisting the worm gear drives the worm wheel, which in turn drives the threaded column to rotate around the rotating part as a fulcrum. This causes the slider to move downwards under the limit of the second guide rod, and the insertion rod to engage with the clamping plate and chuck, thereby completing the positioning of the main roller. The installation and removal of the rollers are reversed, which facilitates the maintenance and replacement of the main roller and improves the practicality of the mechanism. The mechanism controls the second servo motor through the controller to drive the second threaded rod to rotate, which in turn drives the slide block sleeved on the second threaded rod to slide above the sliding frame. When sliding, the pulley set at one end of the auxiliary roller also slides upward with the slope trend of the upper surface of the slide block from gentle to steep, which in turn drives the auxiliary roller to tilt at an angle with one end of the upper surface of the sliding frame as the fulcrum of rotation. This achieves the limitation of the movement range on both sides of the belt and the adjustment of the load, thus improving the practicality of the mechanism.
[0009] Furthermore, both ends of the lower end face of the hanger are fixedly connected to limit slots, and a first guide rod is slidably connected to one side of the outer wall of each of the two limit slots;
[0010] Through the above technical solution, the limiting latch enables the partition to move stably downward as the spring telescopic rod is stretched downward without any deviation.
[0011] Furthermore, insert rods are slidably connected to both sides of the lower end of the second guide rod, and a rotating part is fixedly connected to the lower end of the second guide rod;
[0012] Through the above technical solution, the second guide rod can limit the trajectory of the insertion rod downward and fix the rotating part.
[0013] Furthermore, a slider is threadedly connected to one side of the outer wall of the threaded column, and the periphery of the outer wall of the chuck forms an engaging connection with the middle of the upper end face of the fixed seat.
[0014] Through the above technical solution, the threaded column can drive the slider to move up and down along the thread direction when rotating, and the protrusion in the middle of the upper end face of the fixed seat can provide an accurate placement position for the chuck and play an auxiliary fixing role.
[0015] Furthermore, a second threaded rod is rotatably connected to the middle of the upper end face of each of the two sliding frames, and a sliding seat is slidably connected to the middle of the upper end face of each of the two sliding frames;
[0016] Through the above technical solution, the sliding frame provides a stable rotation fulcrum for the second threaded rod, and the sliding block can improve its sliding stability by using the protruding part of the upper end face of the sliding frame as its travel trajectory.
[0017] Furthermore, both ends of the upper surface of the two side bases are rotatably connected with a first threaded rod, and the middle of the upper surface of the two side bases is slidably connected with a sliding frame.
[0018] Through the above technical solution, the side base provides a stable rotation fulcrum for the first threaded rod, and the sliding of the sliding frame is more stable and less prone to deviation from the travel trajectory. In addition, the change in roller spacing caused by the sliding of the sliding frame can also limit the lateral deviation of the belt.
[0019] Furthermore, pulleys are slidably connected to the upper end faces of both slide blocks;
[0020] Through the above technical solution, the pulley facilitates the adjustment of the tilt angle of the auxiliary roller according to the slope change of the upper end of the slide block.
[0021] Furthermore, the slope of the upper surfaces of both slides exhibits a trend from gentle to steep.
[0022] With the above technical solution, the pulley can easily slide to the highest slope of the upper surface of the slide block.
[0023] This utility model has the following beneficial effects:
[0024] 1. This utility model proposes a belt alignment mechanism for a belt conveyor. The mechanism is positioned by clamping the chuck, connecting rod, and main roller onto the upper end of a fixed base. Then, pulling the pull rod extends the spring telescopic rod and moves the partition plate downward. The downward movement of the partition plate causes the clamping plate below it to move down to a suitable height and embed into the chuck. Then, holding the handle and rotating the clamping plate along the slide rail rotates 90 degrees. Finally, twisting the worm gear drives the worm wheel, which in turn drives the threaded column to rotate around the rotating part as the fulcrum. This causes the slider to move downward under the limit of the second guide rod, and the insertion rod to form a locking connection with the clamping plate and chuck. This completes the installation of the main roller. Disassembly is the reverse process, which facilitates the maintenance and replacement of the main roller and improves the practicality of the mechanism.
[0025] 2. The present invention proposes a belt correction mechanism for a belt conveyor. The mechanism uses a controller to control a second servo motor to drive a second threaded rod to rotate, which in turn drives a slide block sleeved on the second threaded rod to slide above a sliding frame. During sliding, a pulley at one end of an auxiliary roller also slides upward with the slope of the upper surface of the slide block from gentle to steep, thereby causing the auxiliary roller to tilt at an angle with one end of the upper surface of the sliding frame as the fulcrum of rotation. This achieves the limitation of the movement range on both sides of the belt and the adjustment of the load capacity, thus improving the practicality of the mechanism. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Reference Figure 1-3 One specific embodiment provided by this utility model:
[0036] A belt correction mechanism for a belt conveyor includes a fixed base 1, a controller 2, side bases 3, hangers 4, first servo motors 5, first threaded rods 6, and sliding frames 7. Hangers 4 are fixedly connected to both ends of the upper surface of the fixed base 1. The controller 2 is mounted on the upper part of one side surface of the hangers 4. Side bases 3 are fixedly connected to both ends of the fixed base 1. First servo motors 5 are mounted on one end of the upper surface of each of the two side bases 3. First threaded rods 6 are fixedly connected to the output ends of each of the two first servo motors 5. Sliding frames 7 are fitted onto the outer walls of each of the two first threaded rods 6. A convenient disassembly and assembly mechanism 8 is provided at the lower end of the hangers 4. An adjustment mechanism 9 is provided on the upper surface of each of the two sliding frames 7. The convenient disassembly and assembly mechanism 8 includes a spring telescopic rod 81. A partition plate 82 is fixedly connected to the lower end. A first guide rod 83 is fixedly connected to both ends of the upper surface of the partition plate 82. A pull rod 84 is fixedly connected to the middle of one side end face of the partition plate 82. A second guide rod 85 is fixedly connected to both ends of the lower end face of the partition plate 82. A slider 86 is slidably connected to both sides of the outer wall of the second guide rod 85. An insert rod 87 is fixedly connected to both sides of the lower end face of the slider 86. A threaded column 88 is rotatably connected to the middle of the lower end face of the partition plate 82. A worm gear 89 is fixedly connected to one end of the outer wall of the threaded column 88. A worm 810 is meshed with one side of the outer wall of the worm gear 89. A rotating part 811 is rotatably connected to the lower end of the threaded column 88. A retaining plate 812 is rotatably connected to the lower end of the rotating part 811. A retaining groove 813 is provided at both ends of the upper end face of the retaining plate 812. A handle 814 is fixedly connected to one end of the upper surface of the chuck plate 812. A chuck 815 is engaged with both ends of the chuck plate 812. A slide rail 816 is provided on one side of the upper surface of the chuck 815. A connecting rod 817 is fixedly connected to one side of the outer wall of the chuck 815. A main roller 818 is rotatably connected to the upper end of the connecting rod 817. The adjusting mechanism 9 includes two second servo motors 91. A second threaded rod 92 is fixedly connected to the output end of each of the two second servo motors 91. A slide block 93 is fitted onto one side of the outer wall of each of the two second threaded rods 92. An auxiliary roller 94 is rotatably connected to one end of the upper surface of each of the two sliding frames 7. A pulley 95 is rotatably connected to one end of the lower surface of each of the two auxiliary rollers 94. The mechanism connects the chuck 815 with the connecting rod 817 and the main roller 818. Components 18 are snapped into place on the upper end of the fixed base 1 for positioning. Then, pulling the lever 84 extends the spring telescopic rod 81, causing the partition 82 to move downwards. The downward movement of the partition 82 causes the clamping plate 812 below it to move down to a suitable height and engage with the chuck 815. Next, gripping the handle and rotating the clamping plate 812 along the slide rail 816 by 90 degrees, and finally twisting the worm gear 810 to drive the worm wheel 89, which in turn drives the threaded column 88 to rotate around the rotating part 811. This causes the slider 86 to move downwards under the limit of the second guide rod 85, and the insertion rod 87 to engage with the clamping plate 812 and chuck 815, thus completing the installation of the main roller 818. Disassembly is the reverse process, facilitating the maintenance and replacement of the main roller 818 and improving the practicality of the mechanism.The mechanism, controlled by controller 2, drives the second servo motor 91 to rotate the second threaded rod 92, which in turn drives the slide block 93, fitted onto the second threaded rod 92, to slide above the sliding frame 7. During sliding, the pulley 95 at one end of the auxiliary roller 94 also slides upwards along the gradual slope of the upper surface of the slide block 93, causing the auxiliary roller 94 to tilt at an angle with one end of the upper surface of the sliding frame 7 as its fulcrum. This limits the range of movement on both sides of the belt and adjusts the load capacity, improving the practicality of the mechanism.
[0037] Reference Figure 3-6 Both ends of the lower end face of the hanger 4 are fixedly connected to limit slots 819. One guide rod 83 is slidably connected to one side of the outer wall of the two limit slots 819. The limit slots 819 enable the partition 82 to move stably downward as the spring telescopic rod 81 is stretched downward without deviation.
[0038] The lower end of the second guide rod 85 is slidably connected to both sides of the insertion rod 87, and the lower end of the second guide rod 85 is fixedly connected to the rotating part 811. The second guide rod 85 can limit the downward trajectory of the insertion rod 87 and fix the rotating part 811.
[0039] One side of the outer wall of the threaded column 88 is threaded with a slider 86. The outer wall of the chuck 815 is engaged with the middle of the upper end face of the fixed seat 1. The threaded column 88 can drive the slider 86 to move up and down along the thread direction when rotating. The protrusion in the middle of the upper end face of the fixed seat 1 can provide an accurate placement position for the chuck 815 and play an auxiliary fixing role.
[0040] The upper end face of each of the two sliding frames 7 is rotatably connected to a second threaded rod 92, and the upper end face of each of the two sliding frames 7 is slidably connected to a slide block 93. The sliding frame 7 provides a stable rotation fulcrum for the second threaded rod 92, and the slide block 93 can improve its sliding stability by using the protruding part of the upper end face of the sliding frame 7 as its travel trajectory.
[0041] Both ends of the upper surface of the two side bases 3 are rotatably connected to the first threaded rods 6, and the middle of the upper surface of the two side bases 3 is slidably connected to the sliding frame 7. The side bases 3 provide a stable rotation fulcrum for the first threaded rods 6, and the sliding of the sliding frame 7 is more stable and less likely to deviate from the travel trajectory. In addition, the change in the roller spacing caused by the sliding of the sliding frame 7 can also limit the lateral deviation of the belt.
[0042] Both slide blocks 93 have pulleys 95 slidably connected to their upper surfaces. The pulleys 95 facilitate the adjustment of the tilt angle of the auxiliary rollers 94 according to the slope of the upper surface of the slide blocks 93.
[0043] The slope of the upper surface of both slides 93 is gradually increasing, and the pulley 95 can easily slide to the highest point of the upper surface slope of the slide 93.
[0044] Working principle: The mechanism completes positioning by engaging the chuck 815, connecting rod 817, and main roller 818 onto the upper end of the fixed base 1. Then, pulling the pull rod 84 extends the spring telescopic rod 81, causing the partition 82 to move downwards. The downward movement of the partition 82 causes the clamping plate 812 below it to move down to a suitable height and engage with the chuck 815. Next, gripping the handle and rotating the clamping plate 812 along the slide rail 816 rotates 90 degrees. Finally, twisting the worm gear 810 drives the worm wheel 89, which in turn drives the threaded column 88 to rotate around the rotating part 811 as a fulcrum, causing the slider 86 to move along the second guide rod 817. 5. The mechanism moves downward under the limit and makes the insertion rod 87 engage with the card plate 812 and the chuck 815, thereby completing the installation of the main roller 818. Disassembly is the opposite. The mechanism controls the second servo motor 91 through the controller 2 to drive the second threaded rod 92 to rotate, which in turn drives the slide block 93 sleeved on the second threaded rod 92 to slide above the sliding frame 7. When sliding, the pulley 95 set at one end of the auxiliary roller 94 also slides upward with the slope trend of the upper end surface of the slide block 93 from gentle to steep, which in turn drives the auxiliary roller 94 to tilt at an angle with one end of the upper end surface of the sliding frame 7 as the rotation fulcrum.
[0045] 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 specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
