Description

Technical Field

[0001] The utility model relates to the technical field of plastic film blowing machines, in particular to a frame for an adjustable double-layer co-extrusion unfolding type single-winding plastic film blowing machine. Background Technique

[0002] The frame for producing plastic film generally has a cross-shaped structure, and the inner cavity of the frame is hollow. The blowing machine is installed on the central ground inside the frame. Through a wind disc with a certain structure, the molten material (a mixture of polyvinyl chloride, polyethylene, polypropylene, polystyrene, etc.) after heating is extruded by using wind power. When in a flowing state, it is blown into a circular film by compressed air while it is hot, and then the plastic film is obtained through air cooling and shaping. Under the action of wind power and traction force, the plastic film continuously moves upward in a cylindrical shape. The hollow structure inside the frame provides a channel for the upward movement of the plastic film cylinder, that is, the upward channel for the plastic film. The plastic film enters the herringbone plate upward and is flattened. The traction roller presses it to make the plastic film cylinder fit into a flat sheet. The plastic film is wound into a winding device through traction for winding and packaging.

[0003] Due to the action of wind power and the uneven air inside the plastic film cylinder, the plastic film shakes violently during the upward movement, resulting in difficulty in shaping the plastic film, easy scratching on the frame, and lack of support during the subsequent winding of the plastic film, resulting in uneven plastic film and wrinkles, and unevenness during subsequent clamping and pressing, affecting production and causing a decline in the quality of the plastic film, there are problems.
