Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller technology, and in particular to a roller body for preventing deviation. Background Technology
[0002] A roller is a cylindrical part, usually divided into two types: drive roller and driven roller. Rollers play an important role in the fully automated express logistics industry, mainly used for the conveying, sorting, boxing and packaging of goods. In order to prevent the transmission belt from deviating and causing the conveying to malfunction, an anti-deviation roller body is used during the operation of the roller body.
[0003] To address this, patent CN218538217U discloses an anti-deviation roller body, comprising a roller body and a limiting anti-deviation component. The limiting anti-deviation component includes a forward and reverse motor, a worm gear, a forward and reverse screw, a worm wheel, an adjusting rod, an outer limiting ring, and a limiting protrusion. This utility model belongs to the field of roller technology, specifically a conveyor belt with grooves on the outer wall of the roller body that are adapted to the limiting protrusions. The friction between the grooves on the conveyor belt and the limiting protrusions increases the friction between the conveyor belt and the roller body, reducing the probability of deviation. This anti-deviation roller body can limit and block both sides of conveyor belts of different widths, preventing goods from falling.
[0004] While the aforementioned anti-deviation rollers can limit and block both sides of conveyor belts of different widths to prevent goods from falling, their inconvenience in limiting movement makes it easy for the conveyor belt to deviate from the rollers. Furthermore, they are not easy to reduce friction, resulting in low applicability in use. Utility Model Content
[0005] The purpose of this invention is to provide an anti-deviation roller body to solve the defect of existing roller bodies being inconvenient for positioning.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-deviation roller body, including a frame and a roller body;
[0007] Both sides of the top of the frame are provided with cylindrical bodies, and conveyor belts are sleeved on the outer side of the cylindrical bodies;
[0008] The bottom of the frame is provided with a limit structure;
[0009] The limiting structure is equipped with a lubrication structure inside.
[0010] When using this device, the setting of a limit structure enables the device to prevent deviation, thereby improving the applicability of the roller body during use; the setting of a lubrication structure enables the device to reduce friction, thereby improving the convenience of the roller body during use.
[0011] Preferably, the limiting structure includes a threaded rod, a sliding rod, a movable seat, a servo motor, a support plate, a turntable, and limiting rollers. The threaded rod is located at the bottom of the frame, and movable seats are threaded to the outer sides of both ends of the threaded rod. A sliding rod passes through the bottom of each movable seat. A servo motor is mounted on the outer wall of the frame at one end of the threaded rod. A support plate is fixed to the top of each movable seat. Limiting rollers are evenly distributed on one side of the top of the support plate, and one end of each limiting roller extends into the interior of the support plate and is fixed to a turntable. The limiting rollers prevent the conveyor belt from shifting away from the cylinder body, and the turntable reduces the friction between the limiting rollers and the conveyor belt.
[0012] Preferably, the threads at both ends of the threaded rod are in opposite directions, one end of the threaded rod extends to the outside of the frame and is fixedly connected to the output end of the servo motor, and the slide rod and the movable seat form a sliding structure, with both ends of the slide rod fixedly connected to the inner wall of the frame. When the threaded rod rotates, because the threads at both ends of the threaded rod are in opposite directions, the threaded rod drives the movable seats at both ends to move in opposite directions, while the movable seats move outside the slide rod.
[0013] Preferably, the turntable and the support plate form a rotating structure, and the outer side of the limiting roller contacts the inner side of the conveyor belt. Under the action of the slide bar, the moving seat is prevented from rotating along with the threaded rod. The moving seat drives the limiting roller to move through the support plate, so as to limit the conveyor belts of different widths.
[0014] Preferably, the lubrication structure includes a placement groove, a fixing frame, an oil injection hole, a filter screen, an elastic rope, and a sealing cap. The placement groove is located on the top of the support plate. An oil injection hole is provided inside the support plate at the bottom of the placement groove. A fixing frame is provided at the bottom of the placement groove. A filter screen is provided at the bottom of the fixing frame. A sealing cap is provided at the top of the placement groove. An elastic rope is fixed to one side of the sealing cap.
[0015] Preferably, handles are fixed to both sides of the top of the fixed frame, and the end of the elastic rope away from the sealing cover is fixedly connected to the top of the support plate. When the sealing cover and the support plate are separated, the elastic rope prevents the sealing cover from being lost, and lubricating oil is poured into the interior of the fixed frame. Under the action of the filter screen, impurities are kept inside the fixed frame.
[0016] Preferably, the sealing cap and the support plate form an engaging structure, and a handle is fixed to the top of the sealing cap. The filtered lubricating oil contacts the outer side of the turntable through the oil injection hole, thereby reducing the friction between the turntable and the support plate. By moving the fixed frame with the handle, the fixed frame moves the filter screen to the outside of the support plate, so as to clean the impurities inside the filter screen and the fixed frame.
[0017] The present invention provides an anti-deviation roller body, the advantages of which are:
[0018] By setting a limiting structure, the conveyor belt is prevented from deviating from the cylinder body under the limiting action of the limiting roller. Under the action of the turntable, the friction between the limiting roller and the conveyor belt is reduced. When the threaded rod rotates, since the thread directions at both ends of the threaded rod are opposite, the threaded rod drives the moving seats at both ends to move in the opposite direction. At the same time, the moving seats move outside the slide bar. Under the action of the slide bar, the moving seats are prevented from rotating with the threaded rod. The moving seats drive the limiting roller to move through the support plate so as to limit the conveyor belts of different widths. This realizes the function of the device to prevent deviation, thereby improving the applicability of the cylinder body in use.
[0019] By incorporating a lubrication structure, when the sealing cover separates from the support plate, the elastic rope prevents the sealing cover from being lost. Lubricating oil is poured into the interior of the fixed frame, where the filter screen traps impurities. The filtered lubricating oil then contacts the outer side of the turntable through the oil injection hole, reducing friction between the turntable and the support plate. Moving the fixed frame with the handle moves the filter screen to the outside of the support plate, allowing for cleaning of the filter screen and the interior of the fixed frame. This device effectively reduces friction, thus improving the ease of use of the drum. Attached Figure Description

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.
[0027] Please see Figures 1-5 This utility model provides an anti-deviation roller body, including a frame 1 and a roller body 2. Roller bodies 2 are provided on both sides of the top of the frame 1, and conveyor belts 3 are fitted onto the outer sides of the roller bodies 2. A limiting structure 4 is provided at the bottom of the frame 1. The limiting structure 4 includes a threaded rod 401, a sliding rod 402, a movable seat 403, a servo motor 404, a support plate 405, a turntable 406, and a limiting roller 407. The threaded rod 401 is located at the bottom of the frame 1, and movable seats 403 are threadedly connected to the outer sides of both ends of the threaded rod 401. Sliding rods 402 penetrate the bottom of the movable seats 403. A sliding rod 402 is installed on the outer wall of the frame 1 at one end of the threaded rod 401. The top of the servo motor 404 and the moving seat 403 are both fixed with support plates 405. Limiting rollers 407 are evenly arranged on one side of the top of the support plate 405. One end of each limiting roller 407 extends into the interior of the support plate 405 and is fixed with a turntable 406. The threads at both ends of the threaded rod 401 are opposite in direction. One end of the threaded rod 401 extends to the outside of the frame 1 and is fixedly connected to the output end of the servo motor 404. The sliding rod 402 and the moving seat 403 form a sliding structure. Both ends of the sliding rod 402 are fixedly connected to the inner wall of the frame 1. The turntable 406 and the support plate 405 form a rotating structure. The outer side of the limiting roller 407 is in contact with the inner side of the conveyor belt 3.
[0028] Reference Figure 2 and Figure 3As shown, when the cylinder body 2 drives the conveyor belt 3 to rotate, the conveyor belt 3 drives the turntable 406 to rotate inside the support plate 405 through the limiting roller 407. Under the limiting action of the limiting roller 407, the conveyor belt 3 is prevented from deviating from the cylinder body 2. Under the action of the turntable 406, the friction between the limiting roller 407 and the conveyor belt 3 is reduced. The servo motor 404 is started, and the servo motor 404 drives the threaded rod 401 to rotate. Since the thread directions at both ends of the threaded rod 401 are opposite, the threaded rod 401 drives the moving seats 403 at both ends to move in the opposite direction. At the same time, the moving seats 403 move outside the slide rod 402. Under the action of the slide rod 402, the moving seats 403 are prevented from rotating with the threaded rod 401. The moving seats 403 drive the limiting roller 407 to move through the support plate 405 so as to limit the conveyor belts 3 of different widths.
[0029] The limiting structure 4 has a lubrication structure 5 inside. The lubrication structure 5 includes a placement groove 501, a fixing frame 502, an oil injection hole 503, a filter screen 504, an elastic rope 505, and a sealing cover 506. The placement groove 501 is opened on the top of the support plate 405. The bottom of the placement groove 501 is provided with an oil injection hole 503 inside the support plate 405. The bottom of the placement groove 501 is provided with a fixing frame 502. The bottom of the fixing frame 502 is provided with a filter screen 504. The top of the placement groove 501 is provided with a sealing cover 506. An elastic rope 505 is fixed to one side of the sealing cover 506. Handles are fixed to both sides of the top of the fixing frame 502. The end of the elastic rope 505 away from the sealing cover 506 is fixedly connected to the top of the support plate 405. The sealing cover 506 and the support plate 405 form a locking structure. A handle is fixed to the top of the sealing cover 506.
[0030] Reference Figure 3 and Figure 5 As shown, the sealing cover 506 is separated from the support plate 405 by the handle. Under the action of the elastic rope 505, the sealing cover 506 is prevented from being lost. Lubricating oil is poured into the interior of the fixed frame 502. The lubricating oil is filtered through the filter screen 504, so that impurities remain inside the fixed frame 502. The filtered lubricating oil comes into contact with the outside of the turntable 406 through the oil injection hole 503, thereby reducing the friction between the turntable 406 and the support plate 405. The fixed frame 502 is moved by the handle, so that the fixed frame 502 moves the filter screen 504 to the outside of the support plate 405, so as to clean the impurities inside the filter screen 504 and the fixed frame 502.
