Abstract
Description
Technical Field
[0001] This utility model relates to the field of idler roller equipment technology, and in particular to an idler roller bracket that can correct the deviation of the idler roller. Background Technology
[0002] Idler rollers are crucial components of belt conveyors, coming in various types and in large quantities. Their function is to support the conveyor belt and the weight of the material, thereby reducing friction between the belt and the roller. They play a key role in extending the lifespan of the conveyor belt, which accounts for over 25% of the total conveyor cost. Idler roller supports are devices for placing and securing idlers, and their design directly affects the flexibility of the idlers during use.
[0003] Existing idler brackets use an integral fixed structure, with the idler directly fixed to the bracket. When an idler is damaged and needs replacement, the entire idler bracket must be removed, or two or more people must work together to lift the conveyor belt and use tools to remove the idler from the bracket and replace it with a new one. This process is complex and cumbersome, not only time-consuming and labor-intensive, but also affects work efficiency and poses certain safety hazards. In addition, the way the idler is fixed to the bracket means that its tilt angle cannot be adjusted, making it unable to adapt to the needs of different working conditions. Therefore, there is an urgent need for an idler bracket that can correct the idler's deviation to solve these problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a roller support for a roller that can correct deviations.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A roller bracket for a corrective roller includes a base. Rollers for correcting the direction of the conveyor belt are provided at the top and both ends of the base. The top of the base has a disassembly mechanism for quick disassembly of the rollers. The top and both ends of the base have adjustment mechanisms for adjusting the angle of the rollers at both ends. The disassembly mechanism includes three fixed frames. Mounting plates are fixed to the top and both ends of each fixed frame. Rotating rods are rotatably connected to both ends of the mounting plates. Limiting rings are rotatably connected to the outer walls of the rotating rods. A slot is eccentrically formed at one end of the rotating rod. A notch communicating with the slot is formed at one end of the limiting ring. A rotating shaft is fixed to the inner wall of each roller, and locking blocks adapted to the slots are fixed to both ends of the rotating shafts. The locking blocks are inserted into the slots, and then the limiting rings are rotated to offset the notch from the slots and limit the locking blocks.
[0007] Preferably, the rotating rod and the limiting ring are provided with the same rubber ring on their sides that are close to each other. The rubber ring can increase friction and prevent the limiting ring from rotating arbitrarily.
[0008] Preferably, the fixing brackets at both ends of the top of the base are respectively fixed with first connecting rods, and the two first connecting rods are respectively rotatably connected to the fixing bracket at the center of the top of the base, and the fixing bracket at the center of the top of the base is fixed to its surface.
[0009] Preferably, the adjustment mechanism includes mounting grooves at both ends of the top of the base. The inner walls of the two mounting grooves are rotatably connected to the same lead screw. The outer walls of the two lead screws are fitted with matching sliding sleeve moving blocks. The outer walls of the two sliding sleeve moving blocks are rotatably connected to second connecting rods. The other ends of the two second connecting rods are rotatably connected to the bottom of the corresponding fixed frame. The sliding sleeve moving blocks can drive the corresponding fixed frame to adjust the angle, so as to buffer the transition between the conveyor belt idler group and the belt drum, and also facilitate the belt deviation correction during the conveying process.
[0010] Preferably, worm gears are fixed to the outer walls of the two lead screws at their opposite ends, and each worm gear has a worm meshing with it on its outer wall. The worm and worm gear have a self-locking function to limit the movement of the lead screws.
[0011] Preferably, two symmetrical fixing blocks are fixed at both ends of the top of the base, and a worm gear is rotatably connected to the side of the two fixing blocks that are close to each other.
[0012] Preferably, both of the worm gear fixing rods are fixed with knobs.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. Due to the adoption of a disassembly mechanism, by rotating the limiting ring and aligning the notch with the slot, the operator can directly remove the idler roller. Then, the locking block is inserted into the slot through the notch. The limiting ring is then rotated to offset the notch from the slot. The rubber ring increases the friction between the limiting ring and the rotating rod, preventing the limiting ring from rotating arbitrarily. This achieves the effect of quick disassembly of the idler roller, making the disassembly of the idler roller simpler and more intuitive. Even novice operators can get started quickly, reducing training costs, reducing downtime, and improving production efficiency.
[0015] 2. Due to the adoption of the adjustment mechanism, the worm gear is driven to rotate by the knob, which in turn drives the worm wheel to rotate and the lead screw to rotate. Then, the sliding block lifts the second connecting rod and drives the corresponding fixed frame angle adjustment, which makes the conveyor belt idler group and belt drum buffered and transition, and also facilitates belt correction during the conveying process.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-4 A roller bracket for a corrective roller includes a base 1, with rollers 3 for correcting the belt at the top and both ends of the base 1, a disassembly mechanism for quick disassembly of the rollers 3 at the top of the base 1, and an adjustment mechanism for adjusting the angle of the rollers 3 at both ends of the top of the base 1.
[0023] The disassembly mechanism includes three fixed frames 2. Mounting plates 201 are fixed at both ends of the top of the fixed frames 2. Rotating rods 202 are rotatably connected through both ends of the mounting plates 201. Limiting rings 203 are rotatably connected to the outer wall of the rotating rods 202. A slot 205 is eccentrically opened at one end of the rotating rod 202. A notch 206 communicating with the slot 205 is opened at one end of the limiting ring 203. A rotating shaft 301 is fixed to the inner wall of the multiple idler rollers 3. Both ends of the rotating shaft 301 are fixed with a locking block 302 that matches the slot 205. The locking block 302 is inserted into the inside of the slot 205. Then, by rotating the limiting ring 203, the notch 206 is misaligned with the slot 205 and the locking block 302 is limited.
[0024] In this invention, the rotating rod 202 and the limiting ring 203 are provided with the same rubber ring 204 on their sides that are close to each other. The rubber ring 204 can increase friction and prevent the limiting ring 203 from rotating arbitrarily.
[0025] In this utility model, the fixing brackets 2 located at both ends of the top of the base 1 are respectively fixed with first connecting rods 4, and the two first connecting rods 4 are respectively rotatably connected to the fixing bracket 2 at the center of the top of the base 1, and the fixing bracket 2 located at the center of the top of the base 1 is fixed to its surface.
[0026] In this utility model, the adjustment mechanism includes mounting grooves 101 at both ends of the top of the base 1. The inner walls of the two mounting grooves 101 are rotatably connected to the same lead screw 5. The outer walls of the two lead screws 5 are fitted with matching sliding sleeve moving blocks 501. The outer walls of the two sliding sleeve moving blocks 501 are rotatably connected to the two outer walls of the two sliding sleeve moving blocks 501. The other ends of the two second connecting rods 502 are rotatably connected to the bottom of the corresponding fixed frame 2. The sliding sleeve moving blocks 501 can drive the corresponding fixed frame 2 to adjust the angle, so as to buffer the transition between the conveyor belt idler group and the belt drum, and also facilitate the belt deviation correction during the conveying process.
[0027] In this utility model, worm gears 503 are fixed to the outer walls of the two lead screws 5 at their far ends. The outer walls of the worm gears 503 are provided with worms 505 that mesh with them. The worms 505 and worm gears 503 have a self-locking function, which can limit the position of the lead screws 5.
[0028] In this utility model, two symmetrical fixing blocks 504 are fixed at both ends of the top of the base 1, and a worm gear 505 is rotatably connected to the side of the two fixing blocks 504 that is close to each other.
[0029] In this utility model, both worm gears 505 fixing rods are fixed with knobs 506.
[0030] Working principle: In use, first turn knob 506, which will drive worm 505 to rotate. Worm 505 will mesh with worm wheel 503, driving worm wheel 503 to rotate. Then worm wheel 503 will drive lead screw 5 to rotate. Lead screw 5 will drive sliding block 501 to move on its outer wall, which will push second connecting rod 502 and lift one end of one of the fixed frames 2. Through the rotation of first connecting rod 4 with the fixed frame 2 located at the center, the angle of one of the idler rollers 3 can be adjusted, so that the angle of one of the idler rollers 3 can be tilted, so as to buffer the transition between the conveyor belt idler group and the belt drum, and also facilitate the belt correction during the conveying process. By setting worm wheel 503 and worm 505, lead screw 5 can be limited and the angle of fixed frame 2 can be adjusted. Adjustments are made, and then the angle adjustment mechanism of the fixing frame 2 at the other end of the base 1 is adjusted using the same method. When the idler roller 3 needs to be disassembled, the limiting ring 203 is rotated and the notch 206 is connected to the slot 205. Then the user can directly remove the idler roller 3 and remove the locking block 302 from the inside of the slot 205, thus achieving the effect of quick disassembly of the idler roller 3. When replacing the new idler roller 3, the corresponding locking block 302 is passed through the notch 206 and locked into the inside of the slot 205. Then, by rotating the limiting ring 203, the notch 206 and the slot 205 are misaligned, thus achieving the effect of limiting the locking block 302. By setting the rubber ring 204, the operation of the machine is prevented from causing the limiting ring 203 to rotate arbitrarily, which can increase the friction between the limiting ring 203 and the rotating rod 202.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
