Most of the existing technologies are done manually, which has low work efficiency and high labor costs. In addition, when manually putting the bag on, the bag opening is cumbersome. Generally, water or other liquids are manually added to increase the friction between the fingers and the bag to achieve the opening. After the packaging bag is opened, the packaging bag is manually stretched open and then put on. Since human hands are thicker, in order to facilitate the putting on of the product, the opening of the packaging bag needs to be set larger, which further increases the material waste of the packaging bag. Therefore, there is a need for an automatic device for stretching the opening of the packaging bag to facilitate the loading of the product into the packaging bag. Utility Model Content
