Technical Field

[0001] The utility model relates to the technical field of film blowing machine equipment, in particular to a novel adjustable plastic film blowing machine. Background Art

[0002] Plastic film blowing machines heat and melt plastic particles and then blow them into thin films. Plastics are derivatives of petroleum products, and most of them are synthetic resins. They contain a lot of substances that are harmful to health and are difficult to degrade. The unpleasant smells emitted by those plastics may be released by these harmful substances, including amines, phenols, thiols, peroxides, benzene, aldehydes, ketones, vinyl chloride monomers, styrene, acrylates, acrylic acid monomers and unsaturated hydrocarbons. In addition, the solvents used in the plastic processing process will also release a strong chemical odor, affecting the health of production personnel.

[0003] Existing plastic film blowing machines are not easy to flatten plastic films of different thicknesses, which helps to ensure uniform thickness and surface flatness of the film and improve the quality and appearance of the film. Therefore, a new adjustable plastic film blowing machine is proposed.

[0006] Therefore, it is necessary to invent a novel adjustable plastic film blowing machine to solve the above problems. Utility Model Content
