Thickness measuring temperature-controlled automatic adjustment air ring

Abstract

The invention belongs to the field of film production lines of film blowing machines, and particularly relates to a thickness measuring temperature-controlled automatic adjustment air ring. The thickness measuring temperature-controlled automatic adjustment air ring comprises a capacitance probe, a rotating track, a rotating motor, a rotating carbon brush, an automatic temperature-controlled air ring, a film bubble, heating bars, a fan, an electric control cabinet, a mold and a film bubble frame. The lower end of the capacitance probe is fixedly connected with the rotating track. The upper endof the rotating track is fixedly connected with the rotating motor. The lower end of the rotating track is fixedly connected with the rotating carbon brush. The film bubble frame is arranged on the inner side of the rotating track. The film bubble penetrates through the inner side of the film bubble frame. The rotating track is mounted, the rotating motor and the capacitance probe are mounted onthe rotating track, and the rotating carbon brush is designed below the rotating track; the electric control cabinet is further arranged, the thickness deviation coefficient is calculated, a control module achieves heating to generate heat, film deviation is adjusted through the principle that when the air temperature is high, cooling is slow, and films become thinner, and when the air temperatureis low, cooling is fast, and films become thicker, and film thickness is evener.

Description

technical field [0001] The invention relates to the technical field of a film production line of a film blowing machine, in particular to an air ring for automatic adjustment of thickness measurement and temperature control. Background technique [0002] At present, the automatic adjustment of the air ring meets the requirements of the uniformity of the thickness of the high-speed solvent-free composite film. On the film production line of the blown film machine, the raw materials are input into the mold, and the film is extruded through the mold. [0003] The existing advanced film blowing machines are mainly monopolized by Europe and the United States. Their prices are high and their structures are complex. During the production process, the detection accuracy of the film can be further improved, and the thickness uniformity of film production can be further improved. For this reason, a thickness measurement and temperature control automatic adjustment air ring is propose...
