Description

Technical Field

[0001] The utility model relates to the technical field of film blowing machines, in particular to a film blowing machine for film plastic packaging bags. Background Art

[0002] Film plastic packaging bags are packaging bags made of plastic film, which are widely used in daily life and industrial production. They have the advantages of being light, flexible, waterproof and moisture-proof, and low cost. In the existing technology, when blowing film into film plastic packaging bags, the plastic raw material is first poured into a melting barrel to melt, and then the melted raw material is input into the film blowing cylinder for film blowing. However, the plastic particles are conducted to the film blowing structure and blown out. Long-term use will cause the film blowing structure to clog, thereby affecting the final film blowing effect of the film plastic bag.

[0003] After searching, the utility model with patent announcement number CN220242392U discloses a film blowing mechanism for packaging bags. When in use, the filter element in the film blowing cylinder filters the plastic particles, so that the device will not be easily blocked during film blowing operation, and when the film blowing cylinder stops blowing, the filter element and the movable rod lose their force and move downward, causing the vibration frame to vibrate and act on the filter element, so that impurities outside the filter element can be effectively vibrated and fall off. Although it is convenient to reduce the blockage of the film blowing cylinder by plastic particles, the raw materials in the film plastic packaging bags usually contain larger particles, which are not convenient for crushing. The larger particles will still cause blockage to the film blowing cylinder, and it is not convenient for recycling, which easily leads to waste of resources. Utility Model Content
