This equipment is manufactured by Wuhan Jinyi Plastic Machinery in 2007, with a 1400 type 3-layer co extrusion rotary mold. Double wound surface friction. The extruder is placed in a T-shaped configuration.
Nowadays, there are devices that are outdated and aging. Blown film products; Quality degradation, internal bearing damage and material leakage in the rotating mechanism.
Transformation and upgrading;
Upgrade the internal cooling IBC circulation control system. Fully automatic closed-loop control of film width+-2mm, ensuring film width stability. Fast response speed, used in conjunction with internal cooling molds.
Add 2 high-pressure fans. Air inlet and outlet follow control; The flow of air inside the membrane bubble. Alternating circulation of hot and cold air. Improve cooling speed and extrusion yield.
Replace one set of IBC inner cooling three-layer co extrusion molds, use 42CR mold forging materials, 5-axis CNC machining, mirror polishing and electroplating, increase the transparency and glossiness of the film, and improve thickness uniformity.
The cooling high-efficiency air ring adopts a fine tuned local structure and manually adjusts the film thickness deviation.
Principle of membrane bubble automatic control; Update the latest version of Siemens program, using 3 ultrasonic waves to detect the diameter of membrane bubbles. The digital quantity of ultrasonic waves is collected by the AD module and converted into an output analog quantity of 0-10V through the DA module to control the frequency converter, set the film width, and start the inlet and outlet air. PID control calculation, the outlet air discharges the hot air and odor inside the membrane bubble out of the mold body, and the inlet air inputs the natural air from the outside into the membrane bubble, achieving alternating cold and hot cycles and improving the cooling speed of the membrane bubble.
