Description

Technical Field

[0001] This utility model relates to the field of finishing machine technology, specifically a vibration leveling mechanism for a paper finishing machine. Background Technology

[0002] In printing, packaging, and office automation, paper sorting is a crucial process. Its purpose is to align and flatten the edges of stacked papers to meet the precision requirements of subsequent processing (such as cutting, binding, and printing). Traditional paper sorting methods mainly rely on manual adjustment or simple mechanical flattening devices. However, with the improvement of industrial automation, the market's demands for paper sorting efficiency, precision, and adaptability are increasing. Traditional technologies are no longer sufficient to meet actual production needs. For example, a paper sorting machine with patent number CN102167250A lacks paper limiting components. When the paper stack is thin, it is prone to scattering to both sides during sorting, affecting the sorting effect. Secondly, during the flattening process, only one set of springs is used, and the vibration generated directly acts on the placement surface, potentially causing equipment displacement due to vibration. Furthermore, the vibration generated during equipment operation is directly transmitted to the frame or the ground, not only producing significant noise but also accelerating fatigue wear of internal components (such as vibrators and transmission mechanisms), shortening the equipment's lifespan. Finally, during vibration flattening, the equipment has poor stability and is prone to lateral movement, further affecting the paper flattening effect.

[0003] To address the aforementioned issues, there is an urgent need for a structurally optimized and highly adaptable vibration leveling mechanism that can both adaptively limit the movement of paper of varying thicknesses and reduce the negative impact of vibration through shock absorption design, while simultaneously improving the stability of sliding and adjustment, in order to meet the demands of modern industrial production for efficient and precise paper finishing. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a vibration leveling mechanism with optimized structure, strong adaptability, and the ability to improve equipment stability and leveling effect.

[0005] The technical solution adopted by this utility model to achieve the above objectives is as follows: a vibration leveling mechanism for a paper sorting machine, comprising a mounting box, a fixed frame, a paper sorting frame, a limiting component, and a vibrator. Several shock-absorbing feet are fixedly connected to the bottom of the mounting box. The fixed frame is slidably connected inside the mounting box. The paper sorting frame is fixedly connected to the upper end of the fixed frame. The paper sorting frame includes a side baffle, a bottom plate, and a main baffle. The edge of the bottom plate is fixedly connected to the edge of the main baffle, and the bottom plate and the main baffle are perpendicular to each other. The bottom plate is tilted to one side at an angle of 15°-30°. Side baffles are fixedly connected to both sides of the bottom plate and the main baffle. A limiting component is provided on the bottom plate to adapt to leveling operations of paper of different thicknesses. A vibrator is fixedly connected to the middle of the lower end of the fixed frame. The vibration generated by the vibrator levels and aligns the edges of the paper. Several shock-absorbing components are fixedly connected to the bottom of the fixed frame on both sides of the vibrator. The lower ends of the shock-absorbing components are fixedly connected to the bottom of the mounting box. The limiting assembly includes a first movable plate, a second movable plate, a sliding block, a driving block, a limiting plate, a bidirectional lead screw, and a driving device. Two sets of limiting plates are movably connected within the paper sorting rack. The limiting plate is fixedly connected to one side of the edge of the first movable plate. The first movable plate is slidably connected to the upper end of the base plate. Sliding blocks are fixedly connected to both sides of the lower end of the first movable plate. The base plate has two sets of parallel sliding grooves, and the sliding blocks are slidably connected within these grooves. Two sets of second movable plates are slidably connected to the lower end of the base plate, and the second movable plates are fixedly connected to the sliding blocks. A [missing information - likely a design feature] is provided in the middle of each of the second movable plates. The driving block has a threaded hole in its center, through which a bidirectional lead screw is threaded. Both ends of the bidirectional lead screw are rotatably connected to a support plate, which is fixedly connected to the edge of a base plate. Both ends of the bidirectional lead screw pass through the support plate and connect to a driving device. In use, the driving device drives the bidirectional lead screw to rotate, causing the bidirectional lead screw to move towards or away from the driving block. The driving block moves the second movable plate, which in turn moves the sliding block. The sliding block moves the first movable plate, which in turn moves the limiting plate, which adapts to the thickness of the stacked papers to be processed.

[0006] In the above technical solution, sliding guide grooves are respectively provided on both sides of the fixing frame, and sliding guide blocks are slidably connected in the sliding guide grooves. The sliding guide blocks are respectively fixedly connected to the inner wall of the mounting box to improve the sliding stability of the fixing frame inside the mounting box.

[0007] In the above technical solution, the shock-absorbing support includes a damping telescopic rod, a buffer spring, and a support foot. The upper end of the damping telescopic rod is fixedly connected to the bottom of the mounting box, and the other end of the damping telescopic rod is fixedly connected to the support foot. A buffer spring is sleeved on the damping telescopic rod, and the two ends of the buffer spring are respectively connected to the mounting box and the support foot in mutual contact.

[0008] In the above technical solution, the shock absorption component includes a sliding sleeve, a sliding guide rod, and a vibration spring. The lower end of the fixed frame is provided with several guide slots. A sliding guide rod is slidably connected in the guide slots. The other end of the sliding guide rod is fixedly connected to the bottom of the mounting box. A vibration spring is sleeved on the sliding guide rod. The two ends of the vibration spring abut against the fixed frame and the mounting box, respectively.

[0009] In the above technical solution, a number of reinforcing ribs are fixedly connected between the first movable plate and the limiting plate, and two sets of roller frames are fixedly connected to the second movable plate. Rolling wheels are rotatably connected inside the roller frames, and the fixed frame is provided with a sliding groove, in which the rolling wheels are rotatably connected.

[0010] In the above technical solution, the driving device includes a first synchronous pulley, a second synchronous pulley, a first gear, a second gear, a drive motor, and a rotating shaft bracket. The two ends of the bidirectional lead screw are respectively fixedly connected to the first synchronous pulley. The first synchronous pulleys are respectively connected to the second synchronous pulleys through synchronous belts. The second synchronous pulleys are respectively fixedly connected to both ends of the rotating shaft. A plurality of rotating shaft brackets are rotatably connected to the rotating shaft. The rotating shaft brackets are fixedly connected to one side of the fixed frame. A first gear is fixedly connected to the rotating shaft. The first gear meshes with a second gear. The second gear is fixedly connected to one end of the drive motor. The drive motor is fixedly connected to one side of the paper sorting rack.

[0011] The beneficial effects of this utility model are: The limiting component enables adaptive leveling of paper of various thicknesses: through the transmission structure of bidirectional lead screw-drive block-sliding block-first movable plate, the spacing of the limiting plate can be dynamically adjusted according to the thickness of the stacked paper to adapt to the processing needs of paper of different thicknesses; at the same time, the reinforcing ribs between the first movable plate and the limiting plate enhance the connection strength, prevent thin paper from being scattered due to vibration, and significantly improve the edge alignment accuracy.

[0012] The two-stage vibration reduction design reduces the negative impact of vibration: the vibration-damping support feet (damping telescopic rod + buffer spring) at the bottom of the mounting box absorb the overall vibration of the equipment and prevent the vibration from being transmitted to the placement platform; the vibration-damping components (sliding sleeve + sliding guide rod + vibration spring) under the fixed frame isolate the rigid collision between the fixed frame and the mounting box, reduce the fatigue wear of vibration on components such as the vibrator and transmission mechanism, reduce operating noise and extend the service life of the equipment.

[0013] The sliding stability structure ensures reliable leveling process: the sliding guide grooves on both sides of the fixed frame cooperate with the sliding guide blocks on the inner wall of the mounting box to constrain the fixed frame to vibrate only in the vertical direction and prevent lateral displacement; the rolling wheels on the second movable plate are rolled to the sliding guide groove of the fixed frame, which improves the smoothness of the movement of the second movable plate, ensures the precision and stability of the limit plate adjustment process, and further improves the consistency of paper leveling effect.
