Description

Technical Field

[0001] This utility model relates to the field of office equipment technology, specifically an automatic alignment mechanism for stacking office paper. Background Technology

[0002] In office settings and document management, aligning stacked papers is a fundamental and frequently required task. Neatly stacked papers not only facilitate storage and transportation but also improve the efficiency of subsequent processes such as binding and scanning. Currently, common paper alignment methods mainly rely on manual operation or simple mechanical aids, but both have certain limitations.

[0003] Traditional manual alignment methods typically involve operators manually adjusting the edges of the paper to align it with a fixed reference point (such as the edge of a table or a ruler). While this method is flexible, it is inefficient, especially when there is a large quantity of paper or when repeated alignment is required. This significantly increases the workload, and the alignment accuracy is easily affected by the operator's experience, making it difficult to guarantee consistency.

[0004] To improve efficiency, some mechanically assisted alignment devices have emerged on the market. In existing technology, these devices mostly employ two sets of mutually perpendicular fixed alignment plates. The alignment plates restrict the position of the paper by contacting its edge, thus achieving alignment of standard-sized paper (such as A4 and A3 paper). However, the fixed position of the alignment plates in such devices only accommodates paper with regular shapes and uniform sizes. For irregularly shaped paper (such as documents with chamfered corners, irregularly shaped brochures, etc.) or special paper with non-standard sizes, the fixed-angle alignment plates cannot properly fit the paper edge, resulting in poor alignment or even failure to complete the alignment operation.

[0005] Furthermore, the alignment process of existing mechanical alignment devices still requires manual assistance to push the paper to make it fit snugly against the alignment board, essentially remaining a model of "primarily manual intervention with mechanical assistance as a supplement." This operation method not only relies on manpower, but also increases the resistance to manual pushing when the paper is stacked thickly, further increasing the difficulty of operation and making it difficult to meet the needs of efficient and automated office work. Utility Model Content

[0006] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide an alignment mechanism that is easy to operate, saves time and effort, and can be adapted to various paper operations.

The other end of each hydraulic telescopic rod is rotatably connected to the bottom surface of the flipping plate. A sliding groove is provided on the flipping plate, and an alignment device is slidably connected in the sliding groove. One side of the alignment device is connected to the vibration component, which is located on one side of the flipping plate. In use, the hydraulic telescopic rods can drive the flipping plate to rotate. The alignment device on the flipping plate is used to place the stacked paper, and the vibration component is used to drive the alignment device to vibrate up and down along the sliding groove to align the edges of the paper.

[0009] In the above technical solution, the leveling device includes an operating plate, a leveling plate, a hinge shaft, a sliding guide block, a linkage gear, and a fixing device. Two sets of symmetrical hinge shafts are rotatably connected to the middle part of one side of the operating plate. The rotating shaft of the hinge shaft passes through the operating plate and is fixedly connected to the linkage gear. The two sets of linkage gears mesh with each other. Leveling plates are fixedly connected to the outer walls of the hinge shafts. One side of the leveling plate is slidably connected along the surface of the operating plate. Two sets of sliding guide blocks are fixedly connected to the leveling plate on one side of the operating plate. A sliding guide groove is provided on the operating plate. The sliding guide blocks are slidably connected in the sliding guide groove. A fixing device is fixedly connected to the leveling plate on the side away from the hinge shaft. A sliding groove hole is provided on the operating plate. The fixing device is fixedly connected in the sliding groove hole.

[0010] In the above technical solution, the fixing device includes a fixing block, a threaded sleeve, a threaded rod, and a locking block.

One end of the threaded sleeve passes through the fixing block and is fixedly connected to the operating handle. A threaded rod is threadedly connected inside the threaded sleeve. One end of the threaded rod passes through a sliding groove hole and is fixedly connected to the locking block. A guide groove is provided at the opening of the sliding groove hole on the bottom surface of the operating plate. The locking block is slidably connected in the guide groove.

[0011] In the above technical solution, side guide blocks are fixedly connected to both sides of the sliding groove, and side guide grooves are respectively opened on both sides of the leveling device, and the side guide blocks are slidably connected in the side guide grooves.

[0012] In the above technical solution, the vibration assembly includes a crankshaft, a crank arm, a first gear, a second gear, a drive motor, a sliding sleeve, a sliding block, a first spring, a push-pull rod, a guide rod, and a second spring.

The second gear is fixedly connected to one end of the drive motor, which is also fixedly connected to the tilting plate. The crankshaft has several evenly spaced cranks, each crank rotatably connected to a crank arm. The other end of the crank arm is rotatably connected to one end of the sliding sleeve. Several sliding sleeve holes are provided on the opposite side of the groove. The sliding sleeve is slidably connected in the sliding sleeve hole. A sliding sleeve block is slidably connected in the sliding sleeve. A push-pull rod is fixedly connected to one end of the sliding sleeve block. The other end of the push-pull rod passes through the sliding sleeve and is fixedly connected to one side of the operating plate. The inner wall of the sliding groove between the sliding sleeve holes is provided with mounting holes. A guide hole is provided in the mounting hole.

[0013] The beneficial effects of this utility model are:

[0014] 1. This application effectively solves the problem that traditional alignment devices cannot adapt to irregularly shaped paper by using an adjustable-angle alignment device design. In the alignment device, two sets of alignment plates are linked by a hinge shaft and a linkage gear, which can adjust the angle synchronously and fit with the edge of the paper. Whether it is regular paper or irregularly shaped paper with chamfered corners, close contact can be achieved by adjusting the angle of the alignment plates, which significantly improves the compatibility with different paper types.

[0015] 2. The automated vibration alignment mechanism of this application significantly reduces labor consumption. By driving the crankshaft to rotate through the drive motor, the alignment device is driven to vibrate back and forth along the sliding groove via the crank arm, sliding sleeve and push-pull rod. During the vibration, the paper automatically adjusts its edge position and adheres to the alignment plate, eliminating the need for continuous manual pushing of the paper. Especially when dealing with stacks of thick paper, it can still maintain a highly efficient and stable alignment effect, significantly reducing the labor intensity of operators.

[0016] 3. The flip-board structure design of this application enhances the flexibility and stability of use. The tilt angle of the flip-board can be flexibly adjusted via a hydraulic telescopic rod to coordinate with the vibration assembly for paper alignment, thereby saving time and effort.
