Background
In the process of actually producing the film by the plastic film blowing machine set, a film blank is extruded by a circular die head, then the inside of the film blank is blown by high-pressure air, the outside of the film blank is shaped into a film bubble with uniform thickness by cooling air, the film bubble sequentially enters a bubble stabilizing device, a herringbone plate device and a traction device under the action of a traction roller, and then passes through a guide roller device and a coiling device to finally prepare a film roll. In the process that the thin bubble is pulled, the bubble is continuously pulled to move upwards, enters a pulling roller from a herringbone plate, and meanwhile, high-pressure air in the bubble is uniformly extruded in the bubble between a die head and the herringbone plate to form a constant high-pressure air mass, so that the constant blowing-up ratio of the bubble is ensured; the central position of the bubble needs to be controlled not to shift or swing during the drawing process to ensure that the bubble runs smoothly. The principle of the currently known bubble-shaped monitoring system is as follows: the real-time distance measuring instrument measures the actual numerical value between the bubble shape and the film blowing device by detecting the bubble shape, and feeds the detected numerical value back to the film blowing device, so that the film blowing device automatically adjusts the air quantity, and the bubble shape is stable, and the width of the film is constant. The traditional bubble shape stability monitoring system is installed on a bubble stabilizer (the distance is adjusted according to the diameter of the bubble shape, the bubble shape is stabilized without deviation), and the bubble shape stability monitoring system changes along with the change of the diameter of the bubble shape. Since the bubble shape is changed frequently, the reading of the monitoring system is changed, and a constant value cannot be formed, so that the data is unstable, and the film width is not uniform. By using the monitoring mode, the diameter of the bubble is changed within a certain range, the required diameter of the bubble can be achieved by a plurality of operations, the obvious hysteresis phenomenon is caused, the control precision is poor, and for technicians with insufficient experience, the control and operation difficulty is high, which is a disadvantage in the prior art.
