It can effectively wrap, protect and fix various types of goods, thereby ensuring the integrity and stability of the goods during transportation and storage. In order to improve packaging efficiency and quality, a packaging stretch film stretching device has come into being. It is designed to stretch the stretch film through a mechanical device so that the stretch film can fit the surface of the goods more tightly and evenly when wrapping the goods. The existing packaging film stretching device is usually composed of structures such as guide rollers and stretching rollers. However, different goods may require stretch films of different sizes for wrapping, and the length of the existing guide rollers is mostly fixed. Therefore, when the stretch film is in use, due to insufficient stretching force, the stretch film may be offset or folded on the surface of the guide roller, thereby affecting the packaging quality of the goods and greatly reducing the packaging efficiency of the goods. In order to solve the shortcomings of the existing technology, we propose a packaging stretch film stretching device. Utility Model Content
