具体流程包括：

打带：通过自动化打包机，根据预设程序和参数，精确快速地完成对箱体货物的打包固定，保证运输过程中的稳定性。

护角安装：系统自动将纸护角或塑料护角准确无误地安装在箱体的棱角部位，以防止在搬运、装卸、运输过程中因碰撞而导致的货物损坏。

覆顶：采用覆顶装置为箱体顶部提供额外的保护层，防止尘土、雨水等对箱内货物的影响。

缠膜：利用全自动缠绕膜机，将拉伸膜均匀紧密地包裹在箱体外表面，形成一层紧固且防潮防尘的保护膜，进一步增强货物在运输途中的防护性能。

整个过程无需人工干预，极大地提高了生产效率，降低了劳动强度，同时也确保了包装质量的一致性和稳定性，对于提升企业物流效率和降低运营成本具有显著效果。

The online automatic packaging line for large-scale box cargo with corner protection and overlay wrapping film is a high-end automatic packaging equipment, which is mainly used in the logistics packaging link of large-scale production enterprises. The assembly line integrates automatic tape (packing), corner protection installation, roofing, and cargo wrapping, etc., which can carry out all-round and standardized packaging processing of large box goods.

The specific process includes:

Tapping: Through the automatic baler, according to the preset program and parameters, the packaging and fixing of the box goods can be completed accurately and quickly to ensure the stability of the transportation process.

Corner protection installation: The system automatically installs the paper corner protector or plastic corner protector accurately on the edges and corners of the box to prevent damage to the goods caused by collision during handling, loading and unloading, and transportation.

Roofing: The roofing device is used to provide an additional protective layer for the top of the box to prevent the impact of dust, rain, etc. on the goods in the box.

Wrapping film: The stretch film is evenly and tightly wrapped on the outer surface of the box by using the automatic stretch film to form a tight, moisture-proof and dustproof protective film, which further enhances the protective performance of the goods during transportation.

The whole process does not require manual intervention, which greatly improves the production efficiency, reduces the labor intensity, and also ensures the consistency and stability of the packaging quality, which has a significant effect on improving the logistics efficiency of the enterprise and reducing the operating cost.
