Features of semi-automatic multifunctional bottle blowing machine: The newly designed front opening mold closing mechanism makes product retrieval more convenient, smooth, and fast; The sliding part between the template and the shaft adopts a three-layer composite self-lubricating sleeve, which is wear-resistant, has a long service life, and greatly reduces the pollution caused by lubricating oil; The air circuit design separates the action and blowing, and operates low-pressure machinery (locking, sealing, and releasing the rod) to ensure smooth and energy-saving mechanical action. Especially for low-pressure mold locking, protecting the mold, and high-pressure blowing to ensure product molding, to meet the needs of blowing various bottles; The sealing and rod placement adopt a dual cylinder joint design, combining into one and forming a group on each side without interfering with each other. The pole adopts infinite adjustment, which is conducive to product molding and ensures product quality; There are two operation modes: manual and automatic; The infrared heater is equipped with a dedicated water-cooled and air-cooled device to ensure that the bottle mouth does not deform due to heating. This device is made of special aluminum profiles, which are rust free and leak free, and easy to use.
