After the film bubble comes out of the die head, it is pulled to the vacuum sleeve 2. The vacuum sleeve 2 generates negative pressure to adsorb the film bubble on its inner wall and then continues to move upward to the sizing cylinder 3. The wind enters between the sizing cylinder 3 and the film bubble from the wind collecting hood 4 and flows along the axial direction of the sizing cylinder 3, generating a Venturi effect to generate low pressure, further adsorbing the outer wall of the film bubble on the sizing cylinder 3 and then continuing to rise through the bubble stabilizer 6 to be sent to the opening and closing roller group to clamp the film bubble. The heater 5 can heat the sizing cylinder 3 to further soften the film bubble, making it easier to shape and cool and stabilize. The film bubble shaping device of this embodiment uses a vacuum sleeve to adsorb the film bubble to preliminarily shape the film bubble, and uses the wind collecting hood and the sizing cylinder to generate the Venturi effect to further stabilize and cool, making the entire film bubble more stable, avoiding the phenomenon of concave in the film bubble, and effectively improving the quality of the film bubble when clamped into a thin film; at the same time, the heater is used to heat the sizing cylinder, thereby softening the film bubble for a second time, making the film bubble easier to shape and convenient for the herringbone plate to clamp the film.
