The high-speed film blowing machine relates to the technical field of film blowing machines. A transmission mechanism and a guardrail are installed at the upper end of the support frame, an extrusion mechanism is installed at the lower end of the support frame, a feeding mechanism is installed at the upper end of one end of the extrusion mechanism, an extrusion screw is installed horizontally inside the extrusion mechanism, the left end of the extrusion mechanism is connected to the reduction motor, a die head is arranged at the right end of the extrusion mechanism, a high-speed air ring is installed at the upper part of the die head, a fixed core rod is coaxially installed in the middle part of the die head, a cooling fan is installed on the right side of the extrusion mechanism, the cooling fan is connected to the die head and the high-speed air ring, a receiving mechanism is arranged on the right side of the support frame, a sliding guide rail is arranged longitudinally on the support frame, and a control device is slidably installed between the sliding guide rails.
The high-speed air ring used in high-speed film blowing machines includes an upper air ring set, a wind protection ring, a ventilation plate, a second wind protection ring and a wind ring bottom plate in sequence. The bottom of the wind ring bottom plate is provided with an air inlet pipe group in a ring shape, wherein an air outlet is provided in the center of the air ring body, a wind protection ring of the product is provided around the air outlet and has air holes, the ventilation plate of the product is set on the outer bottom of the wind protection ring, and the ventilation plate has air holes, the second wind protection ring of the product is set on the outer side of the ventilation plate, and the second wind protection ring has air holes, an annular wind groove is formed between the upper air ring set and the second wind protection ring of the product, the annular wind groove of the product is connected with the air inlet pipe group of the product, and a ventilation gap is left between the ventilation plate and the wind ring bottom plate of the product; the high-speed air ring is cleverly designed to pass through the air in the main body through reasonable structural transformation, so that the wind blown out from the air outlet is very uniform, and the film of the film blowing machine tube after cooling is evenly cooled, and the quality is improved.
The high-speed film blowing machine saves floor space and is easy to place. The extrusion screw and cooling equipment share a cooling fan to take away the heat of the extrusion screw and ensure product quality.
