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, and the film bubble sequentially enters a bubble stabilizing device, a herringbone plate device and a traction device under the action of a traction roller, then passes through a guide roller device and a coiling device, and finally is manufactured into 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 position of the existing thickness gauge is not convenient enough, so that a telescopic thickness gauge for measuring scissors by scanning the circle center of a blown film is provided.
