Description

Technical Field

[0001] This utility model relates to the technical field of carton conveying equipment, and in particular to a carton conveying anti-deviation mechanism. Background Technology

[0002] In the field of automated carton conveying, traditional carton conveying mechanisms lack efficient lateral limiting and correction structures, which makes it easy for cartons to shift laterally during the conveying process, seriously affecting conveying efficiency and the continuity of subsequent processes. Traditional conveyor systems often rely solely on the friction of the conveyor belt to move cartons, lacking dedicated lateral limiting components. During transport, cartons are easily deviated from the preset path due to factors such as conveyor belt misalignment, equipment vibration, and external airflow interference. Especially at acceleration, deceleration, or turning points, cartons experience significant lateral displacement due to inertial impact, leading to chaotic transport. When these misaligned cartons reach the stacking station, they cannot be accurately aligned, resulting in skewed stacks. This not only reduces stacking stability but may also cause collapse due to a shift in the center of gravity, causing damage to cartons or material loss. Subsequent manual reassembly is required, increasing labor intensity. Severely misaligned cartons may detach from the conveyor belt and become stuck in equipment gaps, causing conveyor line shutdowns and disrupting production continuity. Therefore, these problems need to be addressed. Utility Model Content

[0013] 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.

[0014] Example: See Figures 1 to 5 This utility model discloses a carton conveying anti-deviation mechanism, including a base frame 1. A mounting groove is provided in the middle of the base frame 1, and two rotating shafts are rotatably mounted on the top of the mounting groove. Each rotating shaft is fixedly connected to a conveyor wheel 5, which facilitates close contact with a conveyor belt 4 to ensure effective power transmission. A conveyor belt 4 is sleeved between the two rotating shafts via the conveyor wheels 5, allowing the carton to move stably on it. A gantry frame 8 is fixedly mounted on the top of the base frame 1, providing a mounting carrier for horizontal and vertical limiting components. Sliding grooves are provided on both sides of the bottom of the gantry frame 8, and limiting components are symmetrically arranged on both sides of the gantry frame 8 via the sliding grooves. A height limiting component is provided on the inner wall of the top of the gantry frame 8, and a movable plate 13 is movably mounted at the bottom of the height limiting component, preventing the carton from tilting or shifting due to conveying vibration or wind force.

[0015] In this utility model, a connecting shaft is rotatably provided on the inner wall of the bottom of the mounting groove. A first motor 2 is coaxially fixed to one end of the connecting shaft, and a first pulley is fixed to the connecting shaft. Two second pulleys are fixed to one end of the two rotating shafts. A transmission belt 3 is sleeved between the first pulley and the two second pulleys. The belt 3 facilitates the synchronous transmission of power, making the two conveying wheels 5 rotate at the same speed, ensuring the smooth transport of the carton. The limiting component includes a connecting block 11 slidably disposed in the sliding groove. Two buffer springs 12 are installed on one side of the connecting block 11. A guide plate 9 is fixed to one end of the buffer spring 12. Three connecting grooves are opened on the guide plate 9. Multiple first rollers 10 are rotatably disposed at equal intervals in the three connecting grooves. A threaded groove is opened at the other end of the connecting block 11. The limiting component facilitates the lateral position adjustment to constrain the two sides of the carton, corrects the lateral deviation of the carton during transport, and guides the carton to move stably along the centerline of the conveyor belt 4. Screws 6 are screwed to both sides of the top of the base frame 1. A handwheel 7 is fixed to one end of the screw 6, and the other end of the screw 6 is connected to the connecting block 1 through the threaded groove. The screw-on connection allows for precise control of the screw 6's rotation amplitude via the handwheel 7, enabling fine adjustment of the guide plate 9's position. The height limiting component includes a guide rod 14 mounted on the inner wall of the top of the gantry frame 8 and a threaded rod 15 rotatably mounted on the inner wall of the top of the gantry frame 8. One end of the moving plate 13 is slidably sleeved on the guide rod 14, and the other end is sleeved on the threaded rod 15. Multiple second rollers 19 are equidistantly rotatably mounted at the bottom of the moving plate 13. The height limiting component facilitates vertical height adjustment to constrain the top of the carton. To prevent the cartons from shifting upwards during transport due to vibration, wind, or warping, a lateral limiter is used to achieve three-dimensional anti-shifting of the cartons. One end of the gantry frame 8 has an installation cavity, in which a second motor 18 is installed. The output end of the second motor 18 is coaxially fixed to a worm gear 17. A worm wheel 16 is fixed to the top of the threaded rod 15. The worm wheel 16 meshes with the worm gear 17. The worm wheel 16 facilitates smoother and more precise lifting and lowering of the moving plate 13, and also has a self-locking function to prevent the moving plate 13 from falling down on its own.

[0016] Working Principle: When using this utility model, firstly, connect each electrical component in this application to the power supply body. Then, start the first motor 2 at the bottom of the mounting slot. Its output end drives the first pulley to rotate through the connecting shaft. The first pulley transmits power synchronously to the second pulleys on the two rotating shafts through the belt 3, causing the two rotating shafts and the conveyor wheel 5 fixed thereon to rotate synchronously. The rotation of the conveyor wheel 5 drives the conveyor belt 4 on its surface to run in a fixed direction, conveying the carton placed on the conveyor belt 4 forward. Then, according to the width of the carton, rotate the handwheels 7 on both sides of the base frame 1 to drive the screw 6 to rotate, causing the threaded connecting block 11 to move laterally along the sliding groove at the bottom of the gantry frame 8. Then, through the buffer spring 12, push the guide plate 9 closer to both sides of the carton until the two guide plates 9 form a "guide channel" that matches the width of the carton. If the carton is slightly laterally offset during the conveying process, it will collide with the guide plate 9 on one side. The first roller 10 makes contact, reducing frictional resistance through rolling contact. At the same time, the buffer spring 12 undergoes elastic deformation, generating a reverse thrust to push the carton back to the centerline position of the conveyor belt 4, achieving dynamic correction. Simultaneously, based on the thickness of the carton, the second motor 18 inside the mounting cavity of the gantry 8 is activated, and its output end drives the worm gear 17 to rotate. The worm gear 17 meshes with the worm wheel 16 at the top of the threaded rod 15, driving the threaded rod 15 to rotate. The moving plate 13, sleeved on the threaded rod 15, rises and falls vertically along the guide rod 14 until the second roller 19 at the bottom makes slight contact with the top of the carton. The second roller 19 rolls on the top of the carton, preventing the carton from shifting upward due to conveying vibration, wind force, or its own warping through vertical pressure, and avoiding indentations or scratches on the top of the carton due to rolling contact. The combination of these two measures achieves "all-round, no dead angle" anti-deviation of the carton, thus concluding the use of a carton conveying anti-deviation mechanism.

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.
