Beneficial effect

The invention provides a pre-opening bag device, a film adjusting device, a film feeding device, a bag opening device, a bag making device and a bag feeding sealing device sequentially on the frame, and the device is sequentially or simultaneously completed by the control device. Pre-opening bag of bag material, correcting movement of film bag material, conveying film bag material, opening film bag mouth, cutting and sealing the back part of film bag to form film bag, and opening open film bag into liquid The inner bag is sealed and sealed, and the outer bag of the liquid package is bagged and sealed. The whole process does not require manual operation, is completely automatic, has high production efficiency, does not waste film bags, and has no manual contact in the production process, and is clean and hygienic.

The pre-opening bag device is a bag opening process for unrolling the uncut film roll, which is used for propping the film bag which is electrostatically bonded together to remove the electrostatic attraction and reduce the difficulty of subsequent bag opening. The thin bag material film after the pre-opening bag is transported backward by the film feeding device, and before moving into the film feeding device, the movement of the film bag material is corrected by the film adjusting device to prevent the film feeding device from being stuck after being moved by the film feeding device. . The purpose of the film feeding device is to transport the film bag back to the bag opening device. The bag opening device separates and separates the two layers of film bags to facilitate the next step of supporting the bag. The front end of the film bag after the bag opening is stretched backward by the bag sealing device, and the bag making device cuts the film bag which is advanced for a period of time. And at the cutting edge, the film bag is closed at the back end, and the back end of the film bag is closed to facilitate bagging in the next process. The first step in the bag sealing device is to open the opened film bag and then put it into the liquid bag to be transported to the warehouse to complete all the processes of bagging the entire liquid product.
