Description

Technical Field

[0001] This utility model relates to the field of product packaging technology, specifically a sheet stacking mechanism. Background Technology

[0002] In modern industrial production, to meet multiple requirements during product transportation, such as pressure resistance, scratch protection, and visual labeling, multi-layered composite packaging structures made of dissimilar materials are often used for shipment. For example, in packaging solutions for precision mechanical parts, electronic equipment, and metal products, a sandwich-style stacking structure of bottom corrugated paper → middle steel sheet → top kraft paper is commonly used. This structure balances functionality and economy and has been widely adopted.

[0003] Currently, the stacking of such multi-layered, dissimilar sheet packaging structures still largely relies on manual labor. Operators must manually handle and align sheets of different materials and thicknesses, which is not only labor-intensive, dangerous due to the thin steel sheets, slow in pace, and inefficient overall, but also highly dependent on the operator's skill and focus in terms of stacking quality. In actual production, misalignment between layers, skewed angles, and uneven edges occur frequently, seriously affecting the consistency of packaging appearance and the stability of the stacking structure. It may even cause loose packages or product damage during transportation, resulting in quality risks and economic losses. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Example: Reference Figures 1-4 A sheet stacking mechanism includes a machine base 1, with multiple locking casters 7 fixedly mounted on the bottom of the machine base 1. The multiple locking casters 7 are arranged at the four corners of the bottom of the machine base 1, and preferably four casters 7 are used to improve the flexibility and mobility of the mechanism and facilitate positional movement. It also includes a belt conveyor 2 fixedly mounted on the machine base 1, which can be a Dematic DM-LB series or a New Horse SM-PB01. The machine base 1 is equipped with multiple storage racks 3 for placing dissimilar sheet materials. The number of material racks 3 is 3-4, and they are arranged linearly and equidistantly on the machine base 1. Here, the storage racks 3 are preferably 3. Multiple limiting rods 31 are fixedly connected to the top edge of the storage racks 3 for positioning the thin sheets. Here, the number of limiting rods 31 is 6-10. This mechanism takes 8 as an example. The top of the limiting rods 31 is conical to facilitate material feeding. The machine base 1 is equipped with a stacking assembly, which is used to stack the thin sheets on multiple storage racks 3 sequentially onto the conveyor 2.

[0021] Of course, in other embodiments, the stacking assembly includes a gantry frame 51 fixedly connected to the machine base 1. An electric cross slide 5 is fixedly installed on the gantry frame 51. The model can be Linglong Technology-NS2W360 or Ward Machine Tool-WD1719. The electric cross slide 5 is provided with a negative pressure component for adsorbing the sheet. The negative pressure component includes a support plate 43 fixedly connected to the table surface of the electric cross slide 5. The support plate 43 is provided with multiple negative pressure suction cups 4 and negative pressure pipes 41. The number of negative pressure suction cups 4 is 4 to 6, and they are arranged in a rectangular shape on the support plate 43. The negative pressure suction cups 4 are fixedly connected to the negative pressure pipes 41. A negative pressure device 42 is fixedly installed on the machine base 1.

[0022] Specifically, during use, by activating the electric cross slide 5 and the negative pressure device 42, the negative pressure suction cup 4 is driven to move longitudinally and laterally along the system's preset path. In conjunction with the negative pressure suction cup 4, the dissimilar thin sheets of corrugated paper → middle layer steel sheet → kraft paper on multiple storage racks 3 are sequentially transferred and precisely stacked on the conveyor 2. After a set of dissimilar thin sheets is stacked, the conveyor 2 will move the stacked sheet structure one body length towards the discharge end according to the system's preset instructions. With the continuous stacking of thin sheets by the electric cross slide 5 and the negative pressure suction cup 4 and the continuous transportation by the conveyor 2, the continuous feeding of the thin sheet composite packaging structure is realized, thereby achieving continuous automatic production of the production line, which greatly improves the operating efficiency, the stability of the sheet stacking, and the packaging quality.
