Description

Technical Field

[0001] This utility model relates to the field of automatic correction technology, specifically to an automatic correction transition device. Background Technology

[0002] A belt conveyor is a mechanical device that uses a continuously moving conveyor belt to transport materials. It consists of a conveyor belt, drive rollers, idler rollers, and idlers. Driven by a motor, the drive pulley rotates the circular conveyor belt, enabling the horizontal, inclined, and vertical transport of bulk materials or packaged goods. It features large capacity, low energy consumption, and stable operation, and is widely used in mining, ports, warehousing, chemical, and other fields.

[0003] However, when materials fall from the upstream chute of existing belt conveyors, the lateral speed can cause the materials to scatter left and right on the belt. This means that manual correction is required to align the materials with the center position during subsequent processing. In addition, traditional fixed guide chutes cannot be adjusted in real time according to changes in the width of the material flow, resulting in poor correction effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic correction transition device, including a main shell, a feeding assembly installed inside the main shell, a mounting plate fixedly connected to the top of the main shell, a servo motor fixedly mounted on the left end of the mounting plate, a positive and negative lead screw fixedly connected to the output end of the servo motor, a moving stage threadedly connected to the surface of the positive and negative lead screw, a correction plate fixedly connected to the left end of the moving stage, a limit rod fixedly connected to the end of the correction plate near the moving stage, a limit sleeve slidably connected to the surface of the limit rod, and a falling platform fixedly connected to the inner wall of the main shell.

[0005] The above technical solution involves setting up a main shell, feeding components, mounting plate, servo motor, positive and negative lead screws, moving table, correction plate, limit rod, limit sleeve and falling platform. During operation, the servo motor drives the positive and negative lead screws to rotate, driving the two moving tables to move in opposite directions. The correction plate forms an adjustable guide channel at the top of the falling platform, so that the material is automatically corrected to the center position at the moment of falling.

[0006] As a further improvement to the above solution, two mounting plates are provided, and the two mounting plates are evenly distributed on the top of the main body shell with the top center of the feeding assembly symmetrically arranged.

[0007] Through the above technical solution, the two mounting plates are fixed symmetrically around the center of the feeding assembly, ensuring that the positive and negative lead screws and the moving table are subjected to balanced forces.

[0008] As a further improvement to the above scheme, the number of the moving platforms is set to two, and the two moving platforms are symmetrically distributed around the center of the top of the positive and negative lead screws.

[0009] With the above technical solution, the two moving platforms are symmetrically distributed on both sides of the positive and negative lead screws, ensuring that the positive and negative lead screws can open and close synchronously in a single direction of rotation.

[0010] As a further improvement to the above solution, the bottom of the correction plate is fitted with the top of the falling platform, one end of the limiting sleeve near the correction plate is fixedly connected to the surface of the mounting plate, and the limiting rod passes through the mounting plate.

[0011] Through the above technical solution, the limiting rod passes through the mounting plate and slides inside the limiting sleeve, so that the bottom of the correction plate always fits the top surface of the falling platform, preventing jamming or warping.

[0012] As a further improvement to the above solution, the surface of the mobile platform is provided with a sliding hole, and a sliding strip is slidably connected inside the sliding hole.

[0013] Through the above technical solution, the moving stage slides along the slide bar through the sliding hole, providing additional guidance for the correction plate and reducing the lateral load on the positive and negative lead screws.

[0014] As a further improvement to the above solution, two sliding holes are provided, and the two sliding holes are evenly distributed on the surface with respect to the center of the right end surface of the moving stage. The two ends of the slide are fixedly connected to the two mounting plates at their close ends.

[0015] With the above technical solution, the two sliding holes are symmetrically arranged and the two ends of the slide bar are fixed to the mounting plate to form a double-sided guide, which further improves the rigidity of the moving platform.

[0016] As a further improvement to the above solution, the feeding assembly includes a mounting platform fixedly connected to the surface of the main body shell. A drive motor is fixedly installed inside the mounting platform. A pulley one is fixedly connected to the output end of the drive motor. A pulley two is driven by a transmission belt through the pulley one. A transmission roller is fixedly connected inside the pulley two. A conveyor belt is driven by the surface of the transmission roller.

[0017] Through the above technical solution, the drive motor drives the transmission roller via the pulley pair, so that the conveyor belt can transport the material after it has been corrected from the drop platform.

[0018] As a further improvement to the above solution, the conveyor belt is located below the drop platform.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This invention incorporates a servo motor, forward and reverse lead screws, a moving platform, and a correction plate. During operation, the servo motor drives the forward and reverse lead screws to rotate, causing the two moving platforms to move synchronously in opposite directions on the top of the drop platform. This allows for stepless adjustment of the front-to-back distance above the drop platform, achieving automatic centering and correction before the material falls and is transported. This ensures that if the material deviates during transport, it will not be accurately delivered to the next stage. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example: Please combine Figure 1-4 This embodiment of an automatic correction transition device includes a main body shell 1, a feeding assembly 2 installed inside the main body shell 1, a mounting plate 3 fixedly connected to the top of the main body shell 1, a servo motor 4 fixedly installed at the left end of the mounting plate 3, a positive and negative lead screw 5 fixedly connected to the output end of the servo motor 4, a moving table 6 threadedly connected to the surface of the positive and negative lead screw 5, a correction plate 7 fixedly connected to the left end of the moving table 6, a limit rod 8 fixedly connected to the end of the correction plate 7 near the moving table 6, a limit sleeve 9 slidably connected to the surface of the limit rod 8, and a drop platform 10 fixedly connected to the inner wall of the main body shell 1. Material is fed from the top of the drop platform 10. Since the diameter between the two correction plates 7 decreases from large to small, when the material slides down the surface of the drop platform 10, it will contact the surface of the correction plate 7 before falling, thus guiding the material to the center position of the drop platform 10. Subsequently, the material slides down from the center position of the drop platform 10 above the feeding assembly 2 for feeding.

[0024] During adjustment, the servo motor 4 is started. The output end of the servo motor 4 drives the positive and negative lead screws 5 to rotate. The rotation of the positive and negative lead screws 5 drives the two moving tables 6 to move in opposite directions. The synchronous moving table 6 drives the correction plate 7 to move, so that the distance between the two correction plates 7 increases or decreases at the center of the top of the falling platform 10.

[0025] There are two mounting plates 3, which are evenly distributed on the top of the main body shell 1 with the top center of the feeding assembly 2 symmetrically arranged.

[0026] There are two moving platforms 6, which are symmetrically distributed around the top center of the positive and negative lead screws 5.

[0027] The bottom of the correction plate 7 is in contact with the top of the drop platform 10, and the end of the limiting sleeve 9 near the correction plate 7 is fixedly connected to the surface of the mounting plate 3. The limiting rod 8 passes through the mounting plate 3.

[0028] The surface of the moving platform 6 is provided with a sliding hole 11, and a slide bar 12 is slidably connected inside the sliding hole 11.

[0029] There are two sliding holes 11. The two sliding holes 11 are evenly distributed on the surface with the center of the right end surface of the moving stage 6 symmetrically. The two ends of the slide bar 12 are fixedly connected to the two mounting plates 3 at the ends that are close to each other.

[0030] The feeding assembly 2 includes a mounting platform 21 fixedly connected to the surface of the main body shell 1. A drive motor 22 is fixedly installed inside the mounting platform 21. A pulley 23 is fixedly connected to the output end of the drive motor 22. A pulley 25 is driven by a transmission belt 24. A transmission roller 26 is fixedly connected inside the pulley 25. A conveyor belt 27 is driven by the surface of the transmission roller 26.

[0031] When in use, start the drive motor 22. The output end of the drive motor 22 drives the pulley 23 to rotate. The rotation of the pulley 23 drives the pulley 25 to rotate through the transmission belt 24. The rotation of the synchronous pulley 25 drives the transmission roller 26 to rotate, so that the conveyor belt 27 can perform the transmission work.

[0032] The conveyor belt 27 is located below the drop platform 10.

[0033] The implementation principle of the automatic correction transition device in this application embodiment is as follows: when the material is conveyed, the drive motor 22 is started first. The output end of the drive motor 22 drives the pulley 23 to rotate. The rotation of the pulley 23 drives the pulley 25 to rotate through the transmission belt 24. The rotation of the synchronous pulley 25 drives the transmission roller 26 to rotate, so that the conveyor belt 27 can carry out the conveying work.

[0034] When correcting the material path, the material is fed from the top of the drop platform 10. Since the diameter between the two correction plates 7 decreases from large to small, when the material slides off the surface of the drop platform 10, it will contact the surface of the correction plate 7 before falling, thus guiding the material to the center of the drop platform 10. Then the material slides off the center of the drop platform 10 onto the surface of the conveyor belt 27 for conveying.

[0035] Start the servo motor 4. The output of the servo motor 4 drives the positive and negative lead screws 5 to rotate. The rotation of the positive and negative lead screws 5 drives the two moving tables 6 to move in opposite directions. The synchronous moving tables 6 drive the correction plates 7 to move, so that the distance between the two correction plates 7 increases or decreases at the center of the top of the falling platform 10.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
